Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for attaching a heat shield case for the purpose of shielding the timer, etc. from heat in a cooking appliance controlled by a timer, etc. used in general households. .

Conventional structure and its problems Conventionally, as shown in FIG. 3 is attached to the bottom of the main body, and the inside of the heat shield plate 3 is a separate space from the heating element 1 side, and the heat shield case 4 and the heat shielded object 5 are attached.With this configuration, other heat insulating materials 2
is required, and a large heat shield plate 3 is also required.
Space was also a big problem.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a heat shielding case mounting device that achieves a heat shielding effect using an efficient heat shield plate and reduces the number of parts.

Composition of the Invention The heat shielding case mounting device of the present invention includes a heat shielding object, a heat shielding case, and a heat conduction plate, and a part of the heat conduction plate connects a space on the side of the heating element and a space on the side of the heat shielding case. In addition, the other part of the heat conductive plate is placed in a space with a lower temperature than the space of the heating element 1411. With this structure, the temperature inside the heat shield case can be lowered by using the heat shielded object. It attempts to lower the temperature to the limit.

DESCRIPTION OF EMBODIMENTS A timer case mounting device that is an embodiment of the present invention will be described below with reference to the accompanying drawings.

In Figures 2 and 3, 6 is a main body with a double structure equipped with a heating element 7 inside, 8 is a heat insulating material sandwiched between the double structure parts of the main body, and is mainly used for cooking food after cooking. It is an insulating material for keeping warm. Reference numeral 9 denotes a heat conductive plate, which is fixed integrally with the timer case 10 and the timer 11, and this heat conductive plate 9 is fixed to the bottom of the main body 6 with screws or the like.

The heat 12 radiated from the heating element 7 is transferred to the space 13 on the heating element side.
, and is also sub-radiated to the side surface 9a of the heating element of the heat conduction plate 9. To explain with reference to an enlarged view of a main part showing the flow of heat in FIG. 3, a part of the heat sub-radiated to the side surface 9a of the heat generating element of the heat conduction plate 9 is converted into heat 14 flowing inside the heat conduction plate 9. The space 15 inside the heat conduction plate 9 has little air convection, and the timer 1
1 and the timer cover 10, the heat 18 radiated to the space 17, which is at a lower temperature than the heating element side, is greater than the heat 16 radiated to the heat conduction plate 9. That is, in the space surrounded by the heat conduction plate 9, the heat from the heat generation element 7 is received by the heat conduction plate 9 on the surface 9a on the side of the heat generation element, and is radiated on the surface 9b on the opposite side, so that the temperature does not rise. be.

The above embodiment shows an example regarding heat shielding of the timer 11, but it may also be subject to temperature restrictions such as a board, and in short, the heat conductive plate and the heat insulating material create two spaces. 9. The heat conductive plate may have heat receiving and heat dissipating functions.

Effects of the Invention As is clear from the above embodiments, the case mounting device of the present invention is capable of lowering the internal temperature by providing the heat conduction plate with both heat shielding and heat dissipation effects. This aims to improve reliability and improve product quality.
