Abstract
The utility model discloses a rice cooker with protection circuit, including the pot body with install heat retainer (1), generate heat set (2), fuse (3), kick temperature limiter (4) on the pot body, the heat retainer, generate heat set, fuse, kick temperature limiter establish ties, the metal inner bag bottom at the pot body is installed to the kick temperature limiter. The utility model discloses increased a kick temperature limiter in the circuit of rice cooker, when rice cooker during at improper work or erroneous operation, the temperature of rice cooker reaches certain critical temperature, and kick temperature limiter work disconnection power supply makes the rice cooker bulk temperature can not continue to rise, can not lead to that the scorification is generated heat set, scorification base etc. Plays the guard action. When the rice cooker bulk temperature reduced to a certain setting value, the kick temperature limiter resetd, and the rice cooker can normally be worked. The utility model discloses when improper work of rice cooker or erroneous operation, can play good guard action to the circuit to need just not enable the rice cooker and normally work again through disassembling the maintenance.
Description
Technical field
The utility model belongs to the technical field of household electrical appliance and in particular to a kind of electric cooker with protection circuit.
Background technology
At present, the circuit of electric cooker is typically connected with fuse, when electric cooker internal temperature is too high, can fuse
Device, deenergization, reach the purpose preventing leaking electricity or fire occurs.But, the temperature due to being transmitted on fuse is mainly
By air transmitted, and fuse appearance also matcoveredn, add the factors such as manufacturing process, make fuse fine
Sense temperature within electric cooker, particularly lead to electric cooker internal temperature too high in non-normal working or faulty operation
When, fuse can not be protected electric cooker well and prevent from leaking electricity, and now too high temperature is understood scorification aluminum heat-generating disc and moulded
Material base, thus leading to leak electricity or fire occurring.
Additionally, when electric cooker internal temperature is too high, even if fuse can blow in time, then want to allow electric cooker to recover
Normally, also fuse can only again be installed by disassembling method for maintaining, maintenance cost is higher.
Above-mentioned discussion content purpose is may be with the utility model being described below and/or advocate to reader's introduction
The related technology of various aspects various aspects it is believed that this discussion content contributes to as reader with background's information, with favourable
In more fully understanding various aspects of the present utility model, it is therefore to be understood that being that these discussions are read with this angle, rather than
Recognize prior art.
Utility model content
The purpose of this utility model is to avoid of the prior art not enough and provides a kind of electric meal with protection circuit
Pot, it, in electric cooker non-normal working or faulty operation, can play a good protection to circuit.
The purpose of this utility model is achieved through the following technical solutions：
There is provided a kind of electric cooker with protection circuit, include pot and be arranged in pot warmer, heat-generating disc, melt
Disconnected device, also includes kick temperature limiter, described warmer, heat-generating disc, fuse, the series connection of kick temperature limiter, described kick temperature limiter
It is arranged on the metal inner tube bottom of pot.
Wherein, metal inner tube is close in the temperature-sensitive portion of described kick temperature limiter.
Due to employing above-mentioned structure, the utility model increased a kick temperature limiter in the circuit of electric cooker,
When electric cooker is in non-normal working or faulty operation, the temperature of electric cooker reaches certain critical-temperature, and the work of kick temperature limiter is disconnected
Open power supply, make electric cooker bulk temperature will not continue to rise, be not result in scorification heat-generating disc, scorification base etc., play protection and make
With.When electric cooker bulk temperature is reduced to a certain setting value, kick temperature limiter resets, and electric cooker can normal work.This practicality
New circuit can be played a good protection in electric cooker non-normal working or faulty operation, and do not need to pass through
Disassembling maintenance just can make electric cooker normal work again.
Brief description
Using accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not constituted to of the present utility model
Any restriction, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to following attached
Figure obtains other accompanying drawings.
Fig. 1 is the circuit diagram of the electric cooker with protection circuit.
Specific embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and tool
Body embodiment is described in further detail to the utility model, it should be noted that in the case of not conflicting, the application's
Feature in embodiment and embodiment can be mutually combined.
As shown in figure 1, the electric cooker with protection circuit described in the utility model, including pot be arranged in pot
Warmer 1, heat-generating disc 2, fuse 3, kick temperature limiter 4, the pot of electric cooker is also equipped with the parts such as controlling switch, its
Middle heat-generating disc 2 is arranged on the inner bottom part of the metal inner tube of pot.Described warmer 1, heat-generating disc 2, fuse 3, kick temperature limiter 4
Series connection, described kick temperature limiter 4 is arranged on the metal inner tube bottom of pot it is preferred that the temperature-sensitive portion of described kick temperature limiter 4 is tight
Metal inner bag.
The utility model increases a kick temperature limiter on the custom circuit of electric cooker, and this kick temperature limiter is installed on electricity
Pot for cooking rice metal inner tube bottom, and it is close to metal inner tube.Warmer is temperature in sensing normal range of operation, plays insulation effect；Prominent
Jump temperature limiter is sensing non-normal working or faulty operation leads to too high temperature；The temperature of fuse sensing is unstable, typically
All high than temperature limiter.
During utility model works, when electric cooker is in non-normal working or faulty operation, the temperature of electric cooker reaches certain
Critical-temperature, the temperature now by air transmitted is also not enough to blow fuse, but the temperature conducted by metal inner tube
It is sufficiently great to initiate kick temperature limiter, allows kick temperature limiter to disconnect, thus disconnecting circuit, no longer allow temperature continue to rise, be not result in
Scorification heat-generating disc, scorification base etc., play a protective role.When electric cooker bulk temperature is reduced to a certain setting value, kick limits
Warm device resets, and electric cooker can normal work.
A lot of details are elaborated in order to fully understand the utility model in above description, but, this practicality is new
Type can also be different from other modes described here to implement using other, it is thus impossible to be interpreted as the utility model is protected
The restriction of shield scope.
In a word, although the utility model lists above-mentioned preferred embodiment, it should be mentioned that although the skill of this area
Art personnel can carry out various change and remodeling, unless such change and remodeling deviate from scope of the present utility model, otherwise
Should be construed as being included in protection domain of the present utility model.
