freezer

technical field

The utility model relates to a freezer-refrigerator with a freezer compartment.

Background technique

In recent years, due to the increase of double-career families and the development of frozen food, there are more opportunities to freeze food at home. Therefore, as for the household freezer-refrigerator, the freezer-refrigerator focusing on the capacity of the freezer compartment and the convenience of use has become the mainstream. In addition, not only increasing the capacity of the freezer compartment, but also reducing the installation space of the freezer-refrigerator and saving energy in the cooling operation have become important demands of the society.

As a freezer-refrigerator emphasizing the usability of the freezer compartment, for example, there are freezer-refrigerators in which a plurality of containers having different heights are stacked in the freezer compartment (for example, refer to Patent Documents 1 and 2). In Patent Documents 1 and 2, the container is also pulled out along with the drawing out of the freezer door. Furthermore, in Patent Document 2, a lid is provided on the upper container.

Patent Document 1: Japanese Unexamined Patent Application Publication No. 2005-83681 (Abstract, FIG. 2 )

Patent Document 2: Japanese Unexamined Patent Publication No. 2007-271243 (page 4, FIG. 3 )

Generally, since the temperature difference between the ambient air temperature of the freezer and the internal temperature of the freezer is large, dew may condense on the surface of the freezer main body. In order to prevent condensation, for domestic refrigerators, tube heaters are distributed throughout the main body of the refrigerator. The temperature of the tube heater is about 30°C to 40°C. Usually, the tube heater is installed close to the top, back, side, and outer box sheet metal of the front flange of the freezer.

For the top, back, and sides of the freezer-refrigerator, polyurethane foam insulation materials and vacuum insulation materials can be mounted between the tubular heater and the inner panel of the freezer-refrigerator. The effect of the interior of the box is almost negligible. However, heat insulating materials cannot be placed in the front flange, and due to structural reasons, the heat of the tube heater is transferred to the sheet metal constituting the front flange and easily penetrates into the freezer-refrigerator. In particular, since the temperature inside the freezer is low, more heat from the tube heater enters the freezer than other rooms, which may adversely affect food preservation quality and energy saving.

In Patent Documents 1 and 2, although the effect of improving the usability of the freezer compartment and suppressing the leakage of cold air when the freezer compartment door is closed is obtained, no research has been conducted on the intrusion of heat from the tube heater. Technology to suppress invasion of heat from tube heater is desired.

In addition, in Patent Document 2, a cover is provided on the upper opening of the upper container to prevent leakage of cold air when the door is opened, thereby making it difficult to increase the temperature of the freezer compartment and achieving energy saving. However, there is a problem that the lid is often present with the upper container, and therefore, the user has to open the lid every time, resulting in poor usability.

Utility model content

This invention was made in view of such a problem, and it aims at providing the freezer-refrigerator which can suppress the intrusion of the heat from a tube heater into a freezer compartment. Another object of the present invention is to provide a freezer-refrigerator with good usability, in which it is not necessary to open the lid of the upper container every time in a freezer in which a plurality of containers are stacked.

The freezer-refrigerator related to the utility model includes: a freezer-refrigerator main body, the freezer-refrigerator body having a freezer compartment; a plurality of containers arranged in the vertical direction, when the drawer-type door provided on the front surface of the freezer compartment is pulled out , these containers are pulled out from the freezer together with the drawer type door; The pull-out of the drawer-type door is pulled out together with the upper container, and the top part of the freezer is equipped with a tube heater in the front, and the top part is provided with a tube heater protruding toward the cover side at a position behind the tube heater and extending along the width. The freezer compartment side protrusion extending in the direction, the cover has a cover side protrusion protruding toward the top surface side and extending in the width direction. The space between the cover and the top surface portion of the freezer is partitioned into a front space and a rear space on the side of the tube heater.

According to the present invention, it is possible to obtain a freezer-refrigerator capable of suppressing intrusion of heat from the tube heater into the freezer compartment.

FIG. 9 is an enlarged cross-sectional view of a portion surrounded by a dotted line in FIG. 8 .

Between the freezer ceiling part 12 and the freezer floor part 16 of the freezer 4, the upper container 6 and the lower container 7 are accommodated so that it may overlap in an up-down direction. The lower container 7 is configured to be drawn out in conjunction with the forward drawing of the drawer door 4a. The upper container 6 is disposed on the upper portion of the lower container 7 so as to be movable in the front-rear direction relative to the lower container 7 , and the upper container 6 is pulled out together with the lower container 7 in conjunction with the frontward pulling of the drawer door 4 a.

When in the closed state where the drawer door 4a is closed, the upper opening of the lower container 7 is covered by the upper container 6, and only the rear is opened as the cold air outlet 7a for blowing out cold air from a cooler (not shown). In addition, the lower container 7 is provided with a hole 8b (not shown) on the side, so that the cold air blown into the lower container 7 from the cold air outlet 7a at the rear is formed to flow out of the lower container 7 through the hole 8b on the side. (figure 2).

When the door is closed, the upper opening of the upper container 6 is covered by the cover 8, and only the rear side is opened as the cool air outlet 11. The cover 8 is configured to move in a sliding manner on flanges (not shown) provided on the left and right side walls of the upper container 6, and in order to improve the closeness with respect to the front edge of the upper container 6, a front edge of the cover 8 is provided. liner15. In addition, the lid 8 is made of a transparent material so as not to interfere with the ability to take out and store food.

Because cover 8 is set at upper container 6, airtightness is improved, and can prevent cold air from leaking, but, on the other hand, when cold air is blown in the upper container 6 from the cold air outlet 11 of rear, the airtightness of upper container 6 The internal pressure rises, making it difficult for cold air to enter the upper container 6 . In addition, cold air that has not entered the upper container 6 does not cool the inside of the freezer compartment 4, but enters the return air passage 40, which may cause cooling failure. Therefore, in Embodiment 1, a plurality of holes for passing cold air are provided at a portion of the lid 8 on the front side of half the depth of the freezer compartment 4 at intervals in the left-right direction. 8b. Thus, a flow path is formed in which cold air blown out from the rear cool air outlet 7a into the upper container 6 to cool the upper container 6 flows into the return air path 40 through the front holes 8b. As a result, an increase in the internal pressure in the upper container 6 can be suppressed, and the inside of the upper container 6 can be sufficiently cooled.

Freezer compartment 4 is provided with stopper 14 that restricts the forward movement position of cover 8 on freezer compartment ceiling surface portion 12 . In addition, the lid 8 is provided with a protrusion 8c that is in contact with the stopper 14, and as shown in FIG. Moving forward together, both stop when the protrusion 8c comes into contact with the stopper 14 without further moving forward. Specifically, the positional relationship between the protrusion 8c and the stopper 14 is set so that the cover 8 can move forward to a position where the user can visually confirm the presence of the cover 8, specifically, For example, the cover 8 is moved forward to a position where the user can see the end portion (handle portion 8a) of the cover 8 from above, and the cover 8 is restrained so as not to move forward from this position. The position moves.

In addition, in this Embodiment 1, the structure which suppresses the intrusion of the heat from the tube heater 9 into the freezer compartment 4 is employ|adopted. Specifically, as shown in FIG. 3, a cover-side convex portion 8d is provided on the front side of the cover 8. The cover-side convex portion 8d protrudes toward the top surface portion 12 of the freezer compartment and extends in the entire width direction. In the state where the type door 4a is closed, the cover-side convex portion 8d is in contact with the stopper 14 protruding downward from the top surface portion 12 of the freezer in the front-rear direction (the depth direction of the freezer), thereby physically closing the cover side. The front and back spaces of the convex portion 8d are partitioned (FIG. 2, FIG. 3). Thus, even if the heat generated by the tube heater 9 is transferred to the front flange 10 and enters the inside of the freezer-refrigerator, it only heats the air in the space 13 on the front side of the cover-side convex portion 8d, and does not heat up the air in the space 13 on the front side of the cover-side convex portion 8d. The cover-side convex portion 8 d is heated by the rear air, that is, the air in the return air passage 40 . In this Embodiment 1, the stopper 14 functions as the freezing compartment side convex part which isolates the space 13 from the return air path 40 together with the cover side convex part 8d. In addition, in the first embodiment, the lid-side convex portion 8 d also functions as the handle portion 8 a of the lid 8 .

According to the above structure, the upper container 6 is drawn out together with the lower container 7 by pulling out the drawer-type door 4a forward. Although the lid 8 is pulled forward together with the upper container 6, when the lid 8 moves to a position where the user can visually confirm the lid 8, the protrusion 8c of the lid 8 comes into contact with the stopper 14. , thereby preventing the cover 8 from moving further forward. Thereby, the parts other than the handle part 8a of the cover 8 are located in the position which a user cannot visually confirm within the range of the user's field of view. Therefore, the user's field of view is not blocked by the cover 8, and the visibility of food is not hindered. In addition, when storing or taking out food in the upper container 6 , it is not necessary to open the lid 8 , so that the burden of opening and closing the lid 8 is not imposed on the user.

In addition, when the lid 8 is provided on the upper container 6, the user can seal the upper container 6 by pulling out the lid 8, thereby preventing leakage of cold air. In addition, when taking out food from the lower container 7, what is necessary is just to slide the upper container 6 backward. And, when the drawer type door 4a is closed, the lower container 7 moves backward and toward a predetermined storage position in the freezer compartment 4, and when the lower container 7 is in the storage position ( FIG. 2 ), the lower container 7 is formed. The upper opening of the upper layer container 6 is covered, and the upper opening of the upper layer container 6 is covered by the lid 8 .

According to the first embodiment described above, the space between the cover 8 and the freezer compartment top surface 12 can be blocked in the front-rear direction by the cover-side convex portion 8d provided on the cover 8 and the stopper 14 provided on the freezer compartment 4. Therefore, when the door is closed, the air heated by the heat transferred from the tube heater 9 can be retained in the space 13 on the front side of the lid-side convex portion 8d. Thereby, the air in the return air duct 40 is not heated, and the load increase of the cooler (not shown) can be suppressed, and energy saving can be realized.

In addition, the space 13 functions as an air heat insulating layer, and has an effect of preventing the heat from the tube heater 9 and the outside air from intruding into the box. Accordingly, a reduction in the amount of heat intrusion into the box from the tube heater 9 and the heat from the outside air can be expected. As a result, temperature rise inside the freezer can be avoided, and power consumption can be reduced.

In addition, the cover 8 covering the upper container 6 is formed in such a structure that the cover 8 can be pulled out to a position where the user can visually confirm when the door is opened, and the cover 8 cannot be moved further forward, so that the In the conventional structure, the burden of opening and closing the cover 8 is required every time the drawer door 4a is opened. Moreover, since the part other than the handle part 8a of the cover 8 is located in the position which cannot be recognized visually, it does not block a user's field of vision, and does not hinder the visibility of foodstuffs.

In addition, since the cover 8 is provided with a plurality of holes 8b on the front side than the half of the depth dimension of the upper container 6, it is formed in a structure such that the air is blown into the upper container 6 from the rear of the upper container 6 of the freezer compartment 4. The cold air passes through the upper container 6 and flows out of the upper container 6 through the plurality of holes 8b provided in the front. This prevents poor cooling of the upper container 6 due to an increase in the internal pressure of the upper container 6 and enables efficient cooling. In addition, since the hole 8b is located behind the lid-side convex portion 8d, the heated air in the space 13 does not mix with the cold air in the upper container 6, so that the temperature rise in the upper container 6 can be suppressed, and energy saving can be achieved. .

In addition, in this Embodiment 1, the case where two containers, the upper layer container 6 and the lower layer container 7, are stored in an overlapping manner in the freezer compartment 4 was exemplified, but it may be formed so that three or more containers are stacked and stored The structure of the container may be such that the upper opening of the uppermost container among the plurality of containers pulled out together with the drawer door is provided with a cover for performing the above-mentioned operation.
