Description

[Detailed description of the invention] This invention relates to an underfloor storage lid with a temperature display.
More specifically, it relates to an underfloor storage lid with a temperature display, which includes a heating element 4 built into the lid body 3 for the underfloor storage 2 and a temperature display section 6 provided on the top surface 5 of the lid body 3. be.

Conventional underfloor storage lids simply have a heating element built into the lid body, and it is impossible to tell whether the lid body has risen in temperature unless you touch it directly with your hands or feet, and it is difficult to tell with the naked eye. There are disadvantages in that the state of temperature rise cannot be confirmed visually, and in the case of an electrical failure such as a disconnection, it is not possible to visually confirm the state of temperature rise, so electrical failures cannot be detected just by looking.

The present invention was developed in view of such examples, and the purpose of the present invention is to provide a temperature display section on the top surface of the lid body so that it is possible to know whether or not the temperature of the lid body has risen just by looking at it. To provide a lid for an underfloor storage with a temperature display that can be used to detect electrical failure of the lid body at a glance.

The present invention will be described in detail below according to illustrated embodiments.

A square hole is bored in the floor 1 along the joist 12, and a picture frame 7 is fitted into the edge of the square hole.

The underfloor storage 2 is a square box with an upward opening and an outer flange 8 protruding from the outer periphery of the opening edge.

This underfloor storage 2 is fitted into a square hole in the floor 1 and has an outer flange 8 secured to the frame 7.

The heating element 4 is disposed in the surface portion 11, and a foam 9 is formed on the lower surface of the surface portion 11, and a protective layer 10 such as a protective sheet, a plastic board, or plywood is formed on the entire surface of the lower surface of the foam 9. Furthermore, a temperature display section 6 is provided on the upper surface of the surface section 11, and these form the lid body 3.

The foam 9 serves to prevent heat transfer to the underfloor storage 2.

A frame 13 is attached around the surface portion 11.

Further, the surface portion 11 is made of, for example, a heat insulating material.

The temperature display section 6 includes, for example, liquid crystal ink 6a or temperature-indicating paint 6b (
That is, thermo paint) is printed or applied on the entire surface or a portion of the lid body 3.

The temperature indicating paint 6b is made of, for example, methacrylic acid/vinyl acetate (1:
1) AgHgL (
It is a product in which mercury(II) iodide complex salt (plastic thermostatic pigment) such as mercury(II) iodide (color change temperature: 45°C) is dispersed.

Thus, in winter, the lid body 3 is fitted into the underfloor storage 2 on the kitchen floor 1, the plug 15 led out from the lid body 3 is inserted into an outlet (not shown), and the heating element 4 is energized.

When the heating element 4 generates heat and raises the temperature of the lid body 3, the temperature display section 6 changes color at a constant temperature (approximately 45° C. in the case of the temperature-indicating paint 6b) to notify that the temperature of the lid body 3 has increased.

This temperature display section 6 is reversible and returns to its original color when the temperature of the lid body 3 falls.

In this way, in the present invention, the temperature display section is provided on the top surface of the lid body in which the heating element is incorporated, so that it is possible to tell whether or not the temperature of the lid body has risen to the predetermined temperature just by looking at the lid body. This has the advantage of being able to identify whether the temperature has risen to the specified temperature or not just by looking at the lid body, so the temperature display part will not change color forever even if the electricity is on. If it does not, it is obvious that there is an electrical failure in the lid body, and there is an advantage that the electrical failure in the lid body can be easily confirmed.

In addition, 14 is a ventilation hole provided in the underfloor storage compartment, and it is connected to the underfloor storage compartment 2.
It is designed to constantly supply fresh cold air inside.
