Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a thermostat mounting device in a cooking appliance having a heating chamber.

2. Description of the Related Art Conventional Structures and Problems Generally, cooking appliances with heating chambers, such as electric ovens and gas ovens, are equipped with a thermostat to sense the temperature inside the chamber and control the temperature. The mounting structure of the thermostat is as shown in FIG.
is screwed to the inner surface of the side plate 2 of the heating chamber, and the thermostat 3 is attached to the other piece 1b of the temperature-sensitive metal fitting 1 led out of the chamber.
It has a fixed structure.

With this configuration, the temperature of the refrigerator wall is detected rather than the temperature inside the refrigerator, and accurate temperature control cannot be expected.

For this reason, the configurations shown in FIGS. 2 and 3 have been considered. That is, an L-shaped mounting bracket 5 is installed inside the almost L-shaped temperature-sensitive bracket 4.
, with a gap 6 between the internal piece 4a of the temperature-sensitive metal fitting 4 and the mounting piece 5a of the mounting metal fitting 5, and the external piece 4b of the temperature-sensitive metal fitting 4 and the external piece 5 of the mounting metal fitting 5.
By overlapping the thermostats 7 and attaching the thermostat 7 to this part, and attaching the mounting piece 5a of the mounting bracket 5 to the side plate 8 of the heating chamber, the inner piece 4a of the temperature-sensing bracket 4 can be placed inside the side plate 8. , the side plate 8
It makes it more floating. In the figure, numeral 9 indicates a lead-out hole for the temperature-sensitive metal fitting 4 formed in the side plate 8, numeral 10 indicates a positioning hole, and numeral 11 indicates a mounting screw.

With this configuration, the inner piece 4a of the temperature-sensitive metal fitting 4 is floated above the side plate 8, increasing the contact area with the internal convection, and the heat of the temperature-sensitive metal fitting 4 is difficult to escape to the side plate 8, so it is relatively It is possible to accurately detect the temperature inside the refrigerator. However, since the temperature of the convection flowing through the gap 6 between the inner piece 4a of the heat-sensitive metal fitting 4 and the side plate 8 changes depending on the temperature of the surface of the side plate 8, temperature changes in the central part of the refrigerator cannot be directly transmitted. Moreover, since the inner part 4a protrudes into the inner part of the refrigerator, there is a problem that the inner part 4a deforms when food comes into contact with it.

OBJECTS OF THE INVENTION The present invention takes into account the above-mentioned problems and aims to provide a thermostat mounting device that accurately detects the temperature inside the refrigerator.

Structure of the Invention In order to achieve the above-mentioned object, the present invention mounts an internal piece of a temperature-sensitive metal fitting in a floating manner by a mounting fitting inside a heating refrigerator, and also attaches both to one of the internal piece and the mounting fitting. The structure includes a convection blocking piece that closes the gap between the heating chamber and the temperature-sensitive metal fittings to detect the temperature inside the heating chamber without affecting the side panels of the heating chamber. It is something that exists.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

In the figure, reference numeral 12 denotes a temperature-sensitive metal fitting having a substantially L-shape, and has an inner chamber piece 12a and an outer chamber piece 12b. 13 is a nearly L-shaped mounting bracket,
It has a handle piece 13a and an outside piece 13b. The mounting piece 13a of the mounting bracket 13 has convection blocking pieces 14 bent at its upper and lower edges. This mounting bracket 13 is in a state in which its outside piece 13b is stacked on the inside of the outside piece 12b of the temperature-sensing metal fitting 12, and the convection blocking piece 14 of the mounting piece 13a is in contact with the inside of the inside piece 12a of the temperature-sensing metal fitting 12. Then, the outside pieces 12b and 13
b and the thermostat 15 are connected with a screw 16 and are integrated. The interior piece 12a and the mounting piece 13a
is arranged inside the side plate 17 of the heating chamber, and the outside section 1
2b, 13b are guided out of the refrigerator through holes 18 in the side plate 17, and the mounting piece 13a is fixed to the side plate 17 with screws 19. Note that 20 in the figure is a positioning hole provided in the side plate 17.

According to the above configuration, the inner piece 12 of the temperature-sensitive metal fitting 12
Since part a is floating inward of the side plate 17, the heat of the temperature-sensitive metal fitting 12 does not diffuse to the side plate 17, and the gap between the inner piece 12a and the mounting piece 13a is closed by the convection blocking piece 14. As a result, no convection occurs in this gap, so that the internal chamber piece 12a can detect the internal temperature of the refrigerator without being influenced by the temperature of the side plate 17, and transmit this to the thermostat 15. Furthermore, even if a force is applied to the interior piece 12a by food to be cooked, a cooking plate, etc. as shown by arrow F in FIG. 5, the convection blocking piece 14 functions as a stopper and
to prevent deformation.

In the embodiment described above, the convection blocking piece 14 was provided on the mounting fitting 13, but it may be provided on the temperature sensitive fitting, or the number of this convection blocking piece may be one.

Effects of the Invention As is clear from the description of the above embodiments, in the thermostat mounting device of the present invention, the temperature-sensitive metal fitting to which the thermostat is attached in a thermally conductive manner is effectively attached to the heating chamber, and the temperature inside the heating chamber can be controlled. It is possible to accurately sense the temperature and activate the thermostat, and the inner piece of the temperature-sensing metal fitting is difficult to deform due to external force, so its value is great.
