Description

[Detailed description of the invention] The present invention relates to storages such as refrigerators, freezers, and temperature storages that control the internal temperature within a predetermined temperature range. The purpose is to configure the device to perform temperature detection operations.

Next, embodiments of the present invention will be described in detail based on the drawings.

1 is the storage body, and the front opening has a door 2 that opens and closes this opening.
is pivotally supported on the main body 1.

3 is a recess formed in the earthen wall of the main body 1 with an opening toward the front;
A printed circuit board 4 on which necessary control circuit components such as a storage temperature control circuit are mounted is housed inside.

Reference numeral 5 denotes a control box mounted on the front end of the earthen wall of the main body 1 so as to be located above the door 2 and cover the front surface of the recess 3. The control box 5 includes a switch device for operating the control circuit mounted on the board 4, and an adjustment knob. , a temperature indicator 6, and other parts are attached.

The control box 5 is a box body 5 with a U-shaped cross section.
It has a box shape with caps 5A, 5A fitted on the left and right ends of B and opening at the rear.

Reference numeral 7 denotes an ambient temperature detection element electrically connected to the control circuit device 8 or the control circuit device 8 attached to the control box 5.

To install it, the element 7 is held against the inner surface of the cap 5A by covering it with a heat insulating material 9 such as styrofoam, and the heat insulating material 9 houses the recess 10 for holding the element 7 and the lead wires 12 and 12 of the element 7. The heat insulating material 9 is inserted and held in the control box 5 by utilizing the elasticity of the heat insulating material 9 so as to press and hold the element 7 against the cap 5A.

By means of this insulation material 9, the element 7 is substantially shielded from the heat generating elements of the components of the control circuit through the walls of the control box 5 or through the through holes drilled in the control box 5 opposite the element 7 to the ambient temperature of the storage. to sense.

By holding the element 7 with the heat insulating material 9, no special mounting parts are required.

Further, by elastically holding the heat insulating material 9 inside the control box 5, no holding parts are required.

If the cap 5A is fitted to the box body 5B by inserting the heat insulating material 9 into the cap 5A as shown in FIG. By making the thickness so that it is almost tightly housed between the front wall of 5 and the front end of main body 1, it is possible to prevent movement in the front and back direction, and also to shield heat from the heat generating element, eliminating the need for a special holder. .

The ambient temperature detected by element 7 is displayed on display 6 through the control circuit.
will be displayed.

As described above, in the present invention, the ambient temperature detecting element in the control box is provided between the element and the heat generating element of the control circuit component, and if the element operates to sense the ambient temperature, it is insulated from the heat generating element. Since the structure is equipped with a heat insulating material to ensure that the temperature is high, it is possible to accurately detect the ambient temperature of the storage.

Therefore, accurate display can be achieved when detecting the ambient temperature and displaying the temperature, or accurate operation can be achieved when controlling a predetermined device in the storage depending on the ambient temperature.

Furthermore, since a recess is formed in the heat insulating material to hold the element, there is no need for a special holder for the element, thereby reducing the number of parts and simplifying the assembly process.

In addition, the control box consists of a box body and caps on the left and right ends of the box, and the elements and the heat insulating material are housed in the cap, and the elements are pressed against the cap by the heat insulating material. The installation work is easy, and the device has good ambient temperature detection performance.

Furthermore, since a recess is formed in the heat insulating material to hold the element, there is no need for a special holder for the element, thereby reducing the number of parts and simplifying the assembly process.
