Detailed Description

Referring to fig. 1 to 3, a dehumidifier according to an embodiment of the present application includes a housing 1 and a water absorbent member 2 in the housing for absorbing water, the water absorbent member being configured as absorbent foam, for example. An opening and a plug 3 are arranged below the shell, the plug is used for sealing the opening, and the water absorbing piece can be taken out of the opening under the condition that the opening is opened. For example, the plug is designed as a screw, the external thread of which cooperates with an internal thread designed in the opening, so that the plug can be screwed into the opening and seals the opening, and the water-absorbing element can be removed and placed by unscrewing the plug.

A duct is arranged above the housing, an upper inlet 41 and an upper outlet 42 are arranged on the duct, the gas to be dehumidified enters the duct through the upper inlet and exits the duct through the upper outlet, and the water absorbing member is used for absorbing water in the gas. The guide pipe is a condensation pipe or comprises the condensation pipe, and the water absorbing piece is used for absorbing water condensed by the condensation pipe.

In the embodiment shown in the figures, a condenser tube 4 is provided above the housing, and the water absorbing member is used for absorbing water condensed by the condenser tube. The water-absorbing member fills the space in the condenser tube, for example, and the stopper is pressed into the water-absorbing member, for example, partially, so that the filling degree of the water-absorbing member is increased. And heat insulation foam 45 is arranged on the outermost side of the condensation pipe and used for isolating heat exchange between the condensation pipe and the surrounding environment. By refrigerating the condensation duct, the gas flowing through the condensation duct is cooled by the condensation duct, and moisture contained in the gas is condensed into a liquid state, and then absorbed by the water absorbing member and stored therein.

In the dehumidifier, a water absorbing member is provided in a case to absorb and store moisture removed from gas, and an opening and a stopper to seal the opening are provided below the case, and after the dehumidifier is used for a certain period of time, for example, before the water absorbing member is saturated, the old water absorbing member can be taken out through the opening and a new water absorbing member can be put in through the opening in case of opening the stopper, thereby facilitating maintenance of the dehumidifier and securing a dehumidifying effect of the dehumidifier. Furthermore, in the case of a water-absorbing member in which liquid water is stored, the partially water-soluble components in the gas are absorbed by the water in the water-absorbing member and are thus stored in the water-absorbing member, which is particularly advantageous in the case where these water-soluble components are not required. For example, in the case where the dehumidifier is used in a gas detection apparatus, water-soluble components may interfere with the detection result, and on the one hand, absorption and storage of these water-soluble components by the water absorbing member can eliminate interference of them with the detection result, and on the other hand, interference of the gas detected last time with subsequent detection can be eliminated by timely replacement of the water absorbing member.

In the embodiment shown in the figures, a semiconductor refrigeration plate 6 is arranged outside the condensation pipe. The semiconductor refrigerating sheet utilizes the Peltier effect, and under the condition of power-on, the heating end of the semiconductor refrigerating sheet emits heat and the refrigerating end of the semiconductor refrigerating sheet absorbs the heat. The refrigerating end (right side in the figure) of the semiconductor refrigerating piece is connected with the condensing pipe, for example, the refrigerating end of the semiconductor refrigerating piece is in direct contact with the condensing pipe, so that the condensing pipe is cooled and condensed water can be condensed by the condensing pipe. The heating end (left side in the figure) of the semiconductor refrigerating sheet is connected with the heat conducting piece 7 to dissipate heat, so that the refrigerating efficiency of the semiconductor refrigerating sheet is improved. The heat conducting element is, for example, plate-shaped and made of copper.

In the embodiment shown in the figures, an upper inlet 41 and an upper outlet 42 are provided on the condenser tube, through which inlet the gas to be dehumidified enters the condenser tube and exits the condenser tube through the upper outlet. Furthermore, a lower gas inlet 43 and a lower gas outlet 44 are provided on the housing, through which the dehumidified gas enters the housing and exits the housing through the lower gas outlet, thereby at least partially carrying away the moisture in the water-absorbing member. The dehumidified gas, for example, passes through the gaps in the water absorbing member to take moisture in the water absorbing member and is discharged from the lower air outlet.

The dehumidified gas may originate from the gas flowing out of the upper gas outlet, exit the upper gas outlet, flow into other equipment, such as a gas detector, exit the equipment and flow into the lower gas inlet; or the dehumidified gas may be derived from gas generated or exhausted from other equipment to specifically dry the absorbent member.

Furthermore, the heat generated by the heating end of the semiconductor refrigerating sheet is conducted through the heat conducting piece to heat the water absorbing piece, so that the evaporation of water in the water absorbing piece is accelerated, more water can be discharged through the lower air outlet, the saturation of the water absorbing piece is delayed, and the frequency of replacing the water absorbing piece is reduced as much as possible. In the figure, the heat conducting piece is connected with the plug, and the heat conducting piece heats the plug firstly and then heats the water absorbing piece through the plug, so that the structure is compact. In an embodiment not shown, the heat conducting member may directly heat the water absorbing member. The plug can be fixedly connected with the water absorbing piece, for example, the water absorbing piece is clamped into the plug through a buckle on the plug. When the plug is removed, the water absorbing piece is taken out together, and the step of taking out the water absorbing piece separately is omitted.

A seal 51 is provided between the housing 1 and the condenser tube 4 and a seal 52 is provided between the housing 1 and the stopper 3, the

seals

51,52 sealing off the interior formed by the stopper, the housing and the condenser tube from the surroundings. In addition, the condensation pipe is not in direct contact with the plugs, and the

sealing elements

51 and 52 can also play a role in heat insulation, so that heat exchange among the condensation pipe, the shell and the plugs is prevented, particularly heat exchange among the condensation pipe and the plugs is prevented, and respective functions of the cooler condensation pipe and the hotter plugs are not affected. The housing 1 is made of a material with good heat insulation performance, such as heat insulation plastic.
