Abstract

The utility model provides an electric cooker with an automatic regulating device for an under pan clearance. The electric cooker comprises a pan body, a heating plate, an electric heating pipe, a power supply input device, an under pan, the automatic regulating devices, a base and bolts. Each automatic regulating device consists of an upper cover, a lower cover and springs clamped between an upper cover and the lower cover. The base, the regulating devices and the under pan are penetrated with positioning columns arranged on the bottom of the pan body and are locked onto the bottom of the pan body via bolts, and the regulating devices are pressed and fixed onto the under pan and can support the under pan elastically. When the bottom of the electric cooker deforms under high-temperature thermal strain, the pan body is elastically abutted by the automatic regulating devices, and then the under pan can not move relative to the bottom of the pan body, thereby avoiding generating a clearance between the under pan and the pan body and realizing automatic regulation.

Description

Electric food warmer with gap, chassis self-checking device

[technical field]

The utility model relates to a kind of electric food warmer, refers to a kind of electric food warmer with gap, chassis self-checking device especially.

[background technology]

Electric food warmer has easy to use, and therefore the advantage of easy operating is widely used at civil area.And present electric food warmer structure, as shown in Figure 5, electric food warmer mostly 100 is in pot body 101 bottoms chassis 102 to be set, and between the chassis 101 and the bottom of a pan, being provided with heat-generating disc, heat-generating disc is welded in bottom of pot body, and on heat-generating disc, be welded with heat-generating pipe, described chassis is normally held by bolt is fixed in pot bottom, and electric food warmer bottom heating part (heat-generating disc, electrothermal tube) is coated, and is isolated from the outside.But, after power supply input unit 99 is opened, pot body 101 bottoms are subjected to elevated temperature heat stress to do easily generation deformation of time spent, use easily with the bolt displacement of fixed underpan 102 in the bottom of a pan, make 102 relative pots of bodies in chassis 101 loosening or displacement occur, thereby make chassis 102 and pot body 101 contacts site produce gap 103, thereby potential safety hazard occurs, influence the normal use of electric food warmer.

From the above mentioned, be necessary to design a kind of electric food warmer in fact, address the above problem.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric food warmer with gap, chassis self-checking device, be provided with a self-checking device in the electric food warmer chassis, automatically regulate by set adjusting device when being heated, just can prevent from the gap to occur between chassis and the pot body, to guarantee safe, the normal use of electric food warmer.

For achieving the above object, be achieved through the following technical solutions:

The utility model provides a kind of electric food warmer with gap, chassis self-checking device, comprising: pot body, heat-generating disc, electrothermal tube, power supply input unit, chassis, self-checking device, base and bolt.Heat-generating disc is welded in bottom of pot body, and electrothermal tube is welded on the heat-generating disc, controls to adjust the power supply input by supply unit, is coated by the chassis again, is isolated from the outside.Described adjusting device is made up of loam cake, lower cover, spring, spring clip is located between loam cake and the lower cover, be arranged in base, adjusting device, chassis by the set reference column of bottom of pot body, hold by set bolt again and be fixed on the reference column, thereby adjusting device is fixed suppress between chassis and the base time, because the set spring of adjusting device has the restoring force effect, can carry out resiliency supported to the chassis.Like this, the chassis combines with the pot body, and when the electric food warmer bottom was subjected to the effect of elevated temperature heat stress to produce deformation, the chassis was subjected to the elasticity of adjusting device to replace effect, can prevent when displacement appears in reference column that the relative bottom of pot body in chassis is subjected to displacement, becomes flexible, thereby avoid the gap occurring between pot body and the chassis.

For making above-mentioned technology of the present utility model and architectural feature can further allow the person skilled in the art understand, accompanying drawing under cooperating is further described the utility model with a specific embodiment.

[specific embodiment]

As shown in Figure 1, 2, have the electric food warmer 7 of gap, chassis self-checking device, comprising: pot body 1, heat-generating disc 12, electrothermal tube 13, power supply input unit 70, chassis 2, self-checking device 4, base 5 and bolt 6.

Heat-generating disc 12 is welded in low 11 of pot, and electrothermal tube 13 is welded on the heat-generating disc 12, and electrothermal tube 13 carries out the power supply input by set power supply input unit 70 to be regulated, and heat-generating disc 12 is heated, and by heat-generating disc 12 heat is evenly transmitted and gives pot body 1.Simultaneously 11 be provided with plural reference column 14 in the bottom of a pan.And be provided with plurality of through holes 21 in described chassis 2, when this perforation 21 wears for the set reference column 14 in the bottom of a pan, described self-checking device 4 can be fixed thus and elasticity is resisted against on the chassis 2, by bolt 6 base 5, adjusting device 4, chassis 2 is held and is fixed on the set reference column 14 in pot body 1 bottom.This self-checking device 4 is made up of loam cake 41, lower cover 43, spring 42, described loam cake 41, lower cover 43 all are the hollow cup-shaped, and be provided with the through hole 411,431 (as shown in Figure 4) that runs through, wear for reference column 14, spring 42 is located between loam cake 41 and the lower cover 43.Described chassis 2 is covered on the bottom of a pan 11, the bottom of a pan can be coated, and heat-generating disc 12 that is welded in the bottom of a pan and the electrothermal tube 13 that is welded is isolated from the outside, to form complete electric food warmer.

As Fig. 3, shown in 4, be partial enlarged drawing in A-A cutaway view and the cutaway view among Fig. 2, set chassis 2, self-checking device 4, base 5 are worn by reference column 14, hold by bolt 6 to be fixed thereon.This adjusting device 4 is pressed between chassis 2 and base 5, its loam cake 41 is sunken in the set perforation in chassis 2, fixed in the edge of perforation by set lip limit 410 clips, lower cover 43 is sheathed in the loam cake 41 simultaneously, and set spring 42 is compressed between loam cake 41 and the lower cover 43.Like this, by electrothermal tube 13 when heat-generating disc 12 conducts heat, when electric food warmer bottom 11 produces deformation because of being subjected to the effect of elevated temperature heat stress, sinking displacement takes place even hold the reference column 14 relative thes bottom of a pan 11 of bolt 6, chassis 2 is subjected to adjusting device spring 42 to replace effect because of the restoring force that is produced after compressing, just can prevent chassis pot body 1 loosening and generation displacement relatively, guarantee that the chassis still is coated on the bottom of a pan 11, thereby avoid

pot body

1 and 2 contacts site, chassis the gap to occur.

For embodiment and accompanying drawing only be that this utility model is illustrated, not any restriction in addition, the utility model also can still have other variation embodiment, so allly be familiar with this operator and carry out other pattern under this case invention spirit and implement not breaking away from, the equivalence that all should be considered as this case claim is implemented.
