Between the heat shield plate 3 and the main body case 7 and between the heat shield plate 3 and the heater 2, there are heatproof spaces 52 and 53 for preventing the heat of the heater 2 from reaching the lower surface of the cooker. It is provided.

In particular, the fastener 4 includes a spacer 54 which defines the heat insulating space 52, and the spacer 54 is provided with a ventilation hole 55 so that the space from the heat shield plate 3 to the bottom of the main body case 7 is provided. The heat conduction through the rotor 54 is suppressed.

The body case 7 is made of synthetic resin, and the receiving portion 8 of the cooking plate 1 is opened on the upper surface together with the rim of the heat shield plate 3.

An operation member 27 for turning on and off the heater 2 and setting the temperature is provided on a portion of the main body case 7 that projects to one side of the opening of the receiving portion 8, and a thermostat for controlling the heater, for example, a thermostat. An electric device 31, a set temperature indicator 56, and an operation panel unit 11 equipped with a lighting display unit (not shown) are provided, and a display surface 11a is provided upward.

The operation portion 27a of the operation member 27 is projected laterally through a lateral slit portion 71 formed between the main body case 7 and a cover 70 forming a part of the bottom side of the main body case 7, so that the operation portion 27a can be slid laterally. It is provided in. Legs 57 are attached to the lower surface of the bottom of the body case 7 with screws.

A synthetic resin main body cover 61 as shown in FIGS . 3, 5 and 6 is detachably covered from above on the upper surface of the main body case 7 including the operation panel portion 11.

In the main body cover 61, a claw 62 provided on the lower edge of the operation panel 11 is elastically engaged with a locking portion 63 provided on the lower edge of the main body case 7 so that it can be temporarily fixed to the mounted state. I have to.

An engaging projection 64 as shown in FIGS. 1 and 8 is provided with a screw 68 on the side of the body cover 61 opposite to the operation panel 11.
Installed by.

As shown in FIG. 8, the engaging protrusion 64 has a substantially downward arrow shape, and when the main body cover 61 is properly covered with the main body case 7, the main body case 7 has the shape shown in FIG. The tip end head portion elastically engages with the engagement spring 65 screwed to the stab and is locked in the mounting posture.

A guide 60 is integrally formed on the bottom of the main body case 7 so that this elastic engagement can be achieved easily and surely without the engagement protrusion 64 escaping.

The engaging spring 65 has a free end as an operating portion 66, which projects laterally through a lateral slit 72 formed between the main body case 7 and the main body cover 61, and is provided so as to be slidable laterally. Has been.

A body cover pushing-up spring 73 is attached to the side of the engagement spring 65 of the body case 7 together with the engagement spring 65, and when the engagement protrusion 64 elastically engages with the engagement spring 65 as described above. The engagement protrusion 64 presses the main body cover push-up spring 73 downward to charge it.

As a result, the body cover pushing-up spring 73
Attaches the main body cover 61 to the main body case 7 via the engaging protrusions 64.

However, the engaging spring 65 that elastically engages with the engaging protrusion 64 and elastically locks the main body cover 61 to the proper mounting state on the main body case 7 includes the slit 72 of the main body case 7.
Since the vertical movement of the main body cover is restricted by the action of the main body cover push-up spring 73, the engagement protrusion 64 remains locked at the main body cover push-up spring pressing position. Therefore, the body cover 61 can be stabilized at the proper mounting position.

When the engaging spring 65 is laterally moved by the operating portion 66, the engagement with the tip head portion of the engaging protrusion 64 is released, so that the engaging portion side of the main body cover 61 is moved to the main body. Due to the restoring force of the cover lifting spring 73, the engaging protrusion 65
It is pushed upwards through and is lifted a little from the main body case 7.

In this state, the main body cover 61 is temporarily fixed and the main body cover 61 is separated from the main body case 7 by removing the engagement between the claw 62 and the engaging portion 63 while lifting the part which is slightly floated. Removable.

The main body cover 61 detachably covers the portion of the main body case 7 except the receiving portion 8 for removably receiving the cooking plate 1 and the operation panel portion 11 of the main body case 7, and dust and dust spattered thereon. Spilled juice, fats and cooking juices scattered from the cooking plate 1 attached to the receiving part,
The main body cover itself can receive the material and the like and prevent it from reaching other parts.

Although the main body cover 61 is easily soiled, it can be detached from the main body case 7 and handled independently, and can be washed as a whole because it has no electrical equipment.

The body cover 61 has a see-through cover 74 made of a transparent synthetic resin that allows a predetermined range of the operation panel section 11 to be seen through. The body cover 61 covers the operation panel section 11, but the see-through cover 74 is used. It is possible to allow the user or the like to check various displays on the operation panel unit 11 through the display.

The opening edge 75 of the main body cover 61 facing the opening of the receiving portion 8 of the main body case 7 extends over the opening of the receiving portion 8 as shown by the phantom line in FIG. A cover flange 77, which is located immediately below the outward flange 3a of the plate 3, and which is provided at the opening of the cooking plate 1 and projects outward and extends a little downward, covers the outside of the outward flange 3a of the heat shield plate 3, Further, it can be made to approach close to the upper surface of the main body cover 61.

This makes it difficult for dust, cooking juice, materials, etc. to enter the gap between the cooking plate 1 and the heat shield plate 3 and the gap between the heat shield plate 3 and the main body case 7. be able to.

Further, even when the cooking plate 1 is removed for washing, etc., dust or the like can be prevented from easily entering the gap between the heat shield plate 3 and the main body case 7.

As shown in FIGS. 5 and 6, the see-through cover 74, which is a resin molded product of the main body cover 61, is fitted to the opening window 81 provided in the main body cover 61 from the back side and has its own upper portion. The retaining claws 82 are brought into contact with the rear surface of the rim of the opening window 81 to prevent the upper portion from coming off. In this state, the outer periphery of the transparent cover 74 itself is locked on the rim of the opening window 81. The hook 83 is elastically engaged to prevent the hook 83 from falling off, and the hook window 83 can be fitted to the opening window 81 by a simple operation of only fitting from below.

The electric device 31 has a heat-sensitive rod 84 extending below the bottom of the cooking plate 1, and controls energization of the heater 2 so as to detect the temperature of the cooking plate 1 and maintain the cooking temperature set by the operating member 27. It is supposed to do.

As shown in FIGS. 3, 6 and 7, the heat sensitive rod 84 has a concave groove 87 of an aluminum pressing member 86 housed in a concave portion 85 formed in a part of the heat shield plate 3, Cooking plate 1
Is press-fitted into the groove 88 formed on the lower surface of the bottom of the
The dimensional error and the assembly error are absorbed and brought into close contact with each other so that the temperature of the cooking plate 1 can be accurately and stably sensed.

A pair of left and right legs 86a integrally formed on the lower surface of the pusher 86 are vertically movably fitted to the bottom of the recessed portion 85, and are held upward by a spring 99 while being prevented from being pulled upward by a screw 89. The bias is applied so that the concave grooves 87, 88 come close to each other so that the heat-sensitive rod 84 is press-fitted between them.

As shown in detail in FIG. 4 by disassembling the heater 2, the heater 2 formed by winding the heater wire 92 around the square mica plates 90 and 91 and sandwiching them between the mica plates 93 and 94 is sandwiched. It is a flat so-called surface heater, made of metal
A metal which is housed in a radiator plate 95 which forms a heater case with an open bottom, and which is attached to the radiator plate 95 by fastening a screw 96 as a fastener, a spring washer 101, and a nut 102 at one central point and four peripheral points. It is sandwiched between a back plate 98 made of metal and the heater 2 is pressure-bonded to the heat dissipation plate 95.
I am making it.

This protects the heater 2 and
In addition, the heat of the heater 2 is absorbed by the heat dissipation plate 95
It is easy to reach the cooking plate 1 and the back plate 9 is placed under the main case 7.
8 and the heat shield of the heat shield 3 and the presence of space
It becomes difficult to resonate.

Particularly in this embodiment, the heat dissipation plate 95 and the back plate 98 are provided.
Of the heater 2 and the mica plates 93 and 94 equivalent thereto.
Between the contour and the surface of the heater 2 as shown in FIGS. 2 and 4.
It is arranged with play in the direction. Therefore, the heater 2
Even if the thermal expansion occurs in the surface direction due to the temperature rise, the heat dissipation plate 95 and the back plate
The screws 96 and the like that fasten 98 with the outline portion of the heater 2 and the like.
This is due to the play in the surface direction of the heater 2 held between
It is said that the heater 2 stretches and undulates with others.
So that there is a gap between it and the heat sink 95
It can be solved, and heating of the cooking plate 1 will be insufficient
Such a thing can be prevented.

To attach the heater 2 to the heat shield plate 3 with the screw 51, a cut-and-raised piece 105 formed downward on the back plate 98 is used.

Both the heat radiating plate 95 and the lid 98 are curved in one direction, and the heater 2 to be sandwiched is also forcibly curved.

Corresponding to this, a similar curved surface 97 is formed on the mounting surface received by the heater 2 of the cooking plate 1 so as to be in close contact with the heater 2 via the heat radiating plate 95.

In this way, the heater 2 together with the heat dissipation plate 95
The curved shape as described above improves the deformation rigidity
However, when it comes into contact with another person and receives external force, or when the temperature rises
It is even more difficult for deformation like that to occur, and it has a similar curved shape.
Guarantees surface contact with the surface of the cooking plate 1 that is formed
It will be easy to do .

Further, the heater 2 provided on the heat shield plate 3 fixed along the receiving portion 8 which detachably receives the cooking plate 1 of the main body case 7 has the ceiling wall contacting surface with the cooking plate 1. 95
The heat dissipation plate 95 defined as a is accommodated through the downward opening 95b, and the cooking plate 1 detachably mounted on the contact surface 95a of the heater case 95 has a large contact area through the heat dissipation plate 95. Since the heat is transferred, the heating efficiency is improved.

Further, the heater 2 is thin as a whole and has a small heat capacity, so that even in a high temperature setting state, the heat is sufficiently dissipated and is easily consumed by the cooking plate 1. Therefore, the heating efficiency is improved and the overheating state is less likely to occur. As a result, the temperature can be smoothly lowered from the overheated state or the high temperature setting state, and wasteful temperature maintenance and heat consumption can be eliminated.

Moreover, between the heat radiation plate 95 and the heat shield plate,
A superheated closed space 151 that surrounds the heater 2 and extends under the heater 2 is formed without requiring any special member. The superheated closed space 151 is formed from the heater 2
The amount of heat that is not consumed is trapped, and the heat capacity around the heater 2 is artificially increased, so that it is less affected by the environmental temperature and the temperature of the cooked food without causing the problem of the conventional heating plate. Moreover, since the heat radiation from the heater 2 to the outside is suppressed, it is possible to further improve the heating efficiency while maintaining the set temperature stable, and to sufficiently prevent the thermal influence on the outside.

Insulation under the bottom of the electric cooker is
In addition to the heat-closed space 151 forming one heat-insulating space, the heat-insulating space 42 formed between the heat-shielding plate 3 and the bottom of the body case 7 also works, so that sufficient heat-insulating should be achieved. You can

The outward flange 3a of the mouth edge, the opening edge 75 of the receiving portion 8 of the main body case 7, and the cover flange 77 provided outside the mouth edge of the cooking plate 1 are the same as those in the first embodiment. It is located at the relative position, and prevents dust, spattering oil during cooking, and cooking juice from entering between the parts.

An electric device 31 provided in the operation panel section 11 has a frame 111 supporting a thermostat 112 capable of adjusting temperature and a temperature controller 113. The heat sensitive section 114 of the thermostat 112 is a heat shield plate. 3 is penetrated from the lower side to the upper side to face the upper surface of the heat shield plate 3, and the bottom portion of the cooking plate 1 placed on the heater 2 is brought into contact with the heat shield plate 3.

In order to ensure this contact, the heat-sensitive portion 11
The elastic pad 115 normally projects slightly above the contact position with the cooking plate 1 so that the cooking plate 1 mounted on the heater 2 pushes down the heat-sensitive portion 114 by its own weight and moves onto the heater 2. Closely.
