Embodiment
The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explain the present invention, and is not intended to limit the invention.
Shown in reference picture 1, according to a kind of microwave rice cooker of preferred embodiment of the invention, including pass through hinge support portion 3
The cover assembly 1 and cooker body component 2 being hinged.Thus, cover assembly 1 can around hinge supporting part 3 exist with respect to cooker body component 2
Rotated between open position and capping position.Cooker body component 2 is filled including shell 21, interior pot 22, heating chamber 23 and microwave
24 etc. are put, interior pot 22 can be built in heating chamber 23, microwave generating apparatus 24 is by producing the food in microwave heating in pot 22
Thing.Typically, microwave generating apparatus 24 can be magnetron.Normally, when cover assembly 1 is in capping position, by such as
Then the control of described snap close piece 8 is that microwave generating apparatus 24 is activated；When cover assembly 1 is in an open position
When, then microwave generating apparatus 24 is stopped.Thus, it is possible to avoid unreasonably opening under the non-closing lid state of cover assembly 1
Dynamic microwave generating apparatus 24, prevents microwave radiation caused by user's operating mistake.
However, being difficult to ensure that safety in utilization under some particular conditions merely with the grade conventional control element of snap close piece 8.Example
Such as, when hinge support portion 3 is broken, cover assembly 1 can not reach capping position fully according to initial designs, and in upper lid group
Produce relatively large gap between part 1 and cooker body component 2, the microwave that microwave generating apparatus 24 is produced may by the gap to
It is outer to propagate, it is unfavorable for user security.Therefore, the present invention is extraly provided with the component of control microwave generating apparatus 24, to carry
Safety in utilization under the different situations of high microwave rice cooker.Specifically, in illustrated preferred embodiment, pacify on cover assembly 1
Equipped with magnetic part 5, proximity switch 4 corresponding with the magnetic part 5 is installed on cooker body component 2.When magnetic part 5 and the proximity switch
The distance between 4 be less than predetermined value when, microwave generating apparatus 24 can be activated；When between magnetic part 5 and the proximity switch 4
When distance exceeds the predetermined value, microwave generating apparatus 24 is stopped.Thus, it is broken or hinge when due to hinge support portion 3
When the failure such as departing from and causing the cover assembly 1 not cover normally on cooker body component 2, magnetic part 5 and the distance between 4 of proximity switch
Beyond preset range, cause microwave generating apparatus 24 not start, thus avoid consumer from being encroached on by microwave, with higher
Security.Above-mentioned magnetic part 5 and proximity switch 4 is set to prevent microwave generating apparatus under other improper closing lid states
24 start, and are equally beneficial for improving the security of microwave rice cooker.
It is understood that magnetic part 5 of the present invention can trigger the element of proximity switch 4, such as magnetic to be various
Iron etc..Proximity switch 4 can control microwave generating apparatus 24 with a variety of appropriate formats, and for example it can access proximity switch 4
Start in control circuit, or the signal that is stopped of microwave generating apparatus 24 will be forced to send to control unit etc..
In another preferred embodiment, magnetic part 5 can pacify proximity switch 4 with the transposition of proximity switch 4
Loaded on cover assembly 1, magnetic part 5 is installed on cooker body component 2.Comparatively speaking, proximity switch 4 is installed on the energy of cooker body component 2
It is enough to be more easily set to control microwave generating apparatus 24.
With reference to shown in Fig. 1 to Fig. 4, magnetic part 5 can be installed on cover assembly 1 by fixed block 6, be thus easy to pass through
Fixed block 6 is set to have necessarily elasticity or specific materials and cover assembly 1 is advantageously mounted on., can by this set
So that magnetic block 5 is filled into fixed block 6 in advance first, then pass through the location fit between fixed block 6 and cover assembly 1 so that magnetic
Property block 5 be located at precalculated position, be conducive to improve installation accuracy and accurately triggering proximity switch 4.
Specifically, fixed block 6 could be formed with embeded slot, and magnetic part 5 is accommodated into the embeded slot and towards cooker body component
2.Wherein, cover assembly 1 (door body) can have the tapered annular groove in section, and the circumferential profile of fixed block 6 is stewed along direction
The tapered extension (being such as formed as taper type) in direction of body component 2, is installed in annular groove with can easily stablize.
Accordingly, proximity switch 4 can be installed on the appropriate location in cooker body component 2.With reference to shown in Fig. 5 and Fig. 6, shell
The heating chamber 23 of pot 22 in accommodating is provided with 21, proximity switch 4 can be installed in the heating chamber 23.Wherein, heating chamber 23
Upper end periphery be conventionally formed with the edge 23a radially extended, proximity switch 4 is preferably attached to edge 23a downside.Due to
The edge 23a of heating chamber 23 is relatively close to cover assembly 1 and the sealing fit portion of cooker body component 2, therefore proximity switch 4 is connected
In this can more accurately in response to cover assembly 1 closing lid state.
The edge 23a of heating chamber 23 is usually provided with fixed support 7, for being fixed with the associated components in cooker body component 2.
Proximity switch 4 can be installed on by clamping to the fixed support 7 on the downside of the edge 23a of heating chamber 23.Due to fixed support 7
Can be the legacy device for fixing heating chamber 23, therefore without additionally setting the retaining element of fixed proximity switch 4, can
Proximity switch 4 is connected with better simply stabilized structure.
As above-mentioned, the snap close piece 8 being fitted to each other generally is correspondingly formed on cover assembly 1 and cooker body component 2, for inciting somebody to action
Cover assembly 1 is locked in capping position.It is close to improve because snap close piece 8 is typically provided with hinge support portion 8 relatively
The control accuracy of switch 4, it can be respectively arranged at the side closer to hinge support portion 3 with magnetic part 5.
By taking the situation of the fracture failure of hinge support portion 3 as an example, when the snap close piece 8 on cover assembly 1 and cooker body component 2 coordinates
When, cooker body component 2 lock position downward restraining force is produced to cover assembly 1, this cause its opposite side part slightly to
It is upper to tilt, cause cover assembly 1 slightly larger under normal circumstances compared with the spacing between cooker body component 2, be thus easier to cause connecing
Spacing change between nearly switch 4 and magnetic part 5.Compared to the side for being positioned in close snap close piece 8, this setup
With higher reliability.
Wherein, proximity switch 4, magnetic part 5 and snap close piece 8 can be in same plane with the central axis of cooker body component 2
On, thus the spacing between proximity switch 4 and magnetic part 5 can preferably react the state (whether failing) in hinge support portion 3.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, still, the present invention is not limited thereto.At this
In the range of the technology design of invention, a variety of simple variants, including each particular technique can be carried out to technical scheme
Feature is combined in any suitable manner.In order to avoid unnecessary repetition, the present invention is to various possible combinations
No longer separately illustrate.But these simple variants and combination should equally be considered as content disclosed in this invention, belong to the present invention
Protection domain.
