Referring to fig. 1 to 5, a pressure cooking appliance according to an embodiment of the present invention includes a pot body 100 and a pot cover 200, wherein a heat-insulating cover 300, an inner container 400 and a wire coil assembly are disposed in the pot body 100, the inner container 400 is accommodated in the heat-insulating cover 300, and the wire coil assembly is mounted at the bottom of the heat-insulating cover 300 for heating the inner container 400.
The wire coil assembly of the embodiment comprises an electromagnetic wire coil 500 and a liner support member 600, wherein a sleeve 521 nested in the liner support member 600 is arranged on the electromagnetic wire coil 500, and the liner support member 600 is inserted into the sleeve 521. The liner support 600 is used to support the liner 400 as the name implies, and more particularly: when the pressure cooking appliance is in a pressure cooking state, the liner 400 is pressed to move downwards to act on the liner supporting piece 600 and then is transferred to the heat preservation cover 300 through the liner supporting piece 600, so that the electromagnetic wire coil 500 is prevented from being directly pressed and damaged. The following are exemplary: the electromagnetic wire coil 500 comprises a wire coil support 510 and a wire coil seat 520 which are assembled in a split mode, an electromagnetic induction coil is wound on the wire coil seat 520, a sleeve 521 which penetrates through the wire coil seat 520 from top to bottom is arranged on the periphery of the wire coil seat 520, a through hole 511 is correspondingly arranged on the wire coil support 510, and the liner support 600 is inserted into the sleeve 521 through the through hole 511 and is fixedly connected with the wire coil seat 520 or the heat preservation cover 300.
In order to install the above-mentioned wire coil assembly, the bottom of the heat-insulating cover 300 is provided with an opening 320, and a plurality of wire coil holders 310 are arranged at intervals along the edge of the opening 320, and a specific number of wire coil holders 310 is usually arranged according to the fixing requirement of the wire coil assembly. The bottom of the heat-insulating cover 300 is provided with the opening 320, so that the inner space of the heat-insulating cover 300 is communicated with the space below the pot body 100, the heat dissipation space of the wire coil assembly in the pot body 100 is increased, the heat dissipation of the wire coil assembly is facilitated, the heat dissipation system can directly conduct forced heat dissipation on the wire coil assembly under the condition that the pot body 100 is provided with the heat dissipation system, more favorable heat dissipation conditions are provided, the working reliability of the wire coil assembly is ensured, and the service life of devices is prolonged; in addition, the arrangement of the opening 320 also saves the material of the heat-preserving cover 300, thereby reducing the manufacturing cost of the heat-preserving cover 300.
For better heat dissipation, after the wire coil assembly is installed in the heat-insulating cover 300, a certain gap is kept between the electromagnetic wire coil 500 and the bottom of the heat-insulating cover 300 by the support of the sleeve 521 or the liner support 600, so as to provide a heat dissipation space for the electromagnetic wire coil 500, for example, in the present embodiment, a gap of at least 20mm is kept between the wire coil seat 520 (except the sleeve 521) and the wire coil fixing seat 310,
the electromagnetic wire coil 500 of this embodiment is circular, and in order to ensure the uniqueness of the installation position of the electromagnetic wire coil 500 in the heat-insulating cover 300, the electromagnetic wire coil 500 is further provided with a fool-proof column 522, one of the wire coil fixing seats 310 at the bottom of the heat-insulating cover 300 is provided with a fool-proof hole 311, and the electromagnetic wire coil 500 is installed in the heat-insulating cover 300 at the position where the fool-proof column 522 is inserted into the fool-proof hole 311 and is fixed. In the prior art, the fool-proof column is independently arranged on the outer peripheral side of the wire coil seat (refer to the position of the screw column 523 on the outer peripheral side of the wire coil seat 520 in fig. 5), and in consideration of the requirement of the heat dissipation space, the fool-proof column can be inserted into the fool-proof hole only when being at least larger than 20mm to realize fool-proof installation of the electromagnetic wire coil, but the fool-proof column is generally of a long and thin structure, and the longer the length is, the easier the bending or the breakage degree is weakened, so that the electromagnetic wire coil loses the fool-proof function.
For solving above-mentioned problem, this embodiment will prevent slow-witted post 522 and set up on sleeve 521, prevent slow-witted post 522 and sleeve 521 as a holistic fool-proof structure, because sleeve 521 intensity will be greater than prevents slow-witted post 522 for whole prevent slow-witted structural stability is better, has reduced bending, the fracture risk of preventing slow-witted post 522. Referring to fig. 3-5, exemplary: the fool-proof post 522 is integrally formed on the outer side surface of the sleeve 521, as can be seen from fig. 4 and 5, the fool-proof post 522 and the sleeve 521 both extend downwards from the bottom surface of the wire coil seat 520, one side of the fool-proof post 522 is connected to the outer side surface of the sleeve 521, the bottom surface of the fool-proof post 522 is lower than the bottom surface of the sleeve 521, and the portion of the fool-proof post 522 extending out of the bottom surface of the sleeve 521 is inserted into the fool-proof hole 311 to achieve fool-proof. The sleeve 521 increases the bending strength of the fool-proof column 522 in the length direction of the fool-proof column 522, and particularly, stress concentration at the root of the fool-proof column 522 can be avoided, so that the bending and breaking risks of the fool-proof column 522 are reduced, the fool-proof column 522 can also increase the strength of the sleeve 521, and a more stable fool-proof and supporting structure is formed.
Preferred as the above examples are: fool-proof post 522 is disposed on the outer side of sleeve 521 facing away from the center of electromagnetic wire coil 500. In combination with the wire coil fixing seat 310, the fool-proof hole 311 is disposed on the wire coil fixing seat 310, and if the fool-proof post 522 is disposed on the outer side surface of the sleeve 521 close to the center of the electromagnetic wire coil 500, a sufficient space needs to be reserved at a corresponding position on the wire coil fixing seat 310 to dispose the fool-proof hole 311, which results in an increase in the radial width of the wire coil fixing seat 310, a reduction in the size of the opening 320, and a disadvantage of heat dissipation; and will prevent slow-witted post 522 and set up the lateral surface that deviates from electromagnetic wire coil 500 center at sleeve 521, can solve above-mentioned problem, under the circumstances that guarantees that drum fixing base 310 can stable support and fixed electromagnetic wire coil 500, reduce drum fixing base 310's radial width as far as possible, not only do benefit to the heat dissipation, can also enlarge electromagnetic wire coil 500's radial dimension, obtain better electromagnetic induction heating effect.
Preferred as the above examples are: the fool-proof post 522 is a hollow structure, and a larger diameter than a solid post can be obtained by using the same material, so that a larger bending strength can be obtained.
In one embodiment of the present invention, a pressure cooking appliance according to the above embodiment: the fool-proof column is arranged on the bottom surface of the sleeve. From the foregoing embodiments, it can be seen that: after the heat preservation cover bottom is installed to the electromagnetism drum, support through the sleeve and make the electromagnetism drum and keep the clearance between the heat preservation cover bottom, the clearance size is decided by sleeve length, compare prior art and set up the slow-witted post of preventing on the drum alone, will prevent that slow-witted post setting is when the sleeve bottom surface, sleeve length compensation above-mentioned clearance, prevent that slow-witted post only need satisfy with heat preservation cover bottom prevent slow-witted cooperation length can, for example prevent that slow-witted post length only need satisfy with prevent that the grafting in slow-witted hole can, thereby can shorten greatly and prevent slow-witted post length, improve its bending strength, thereby reduce and prevent bending of slow-witted post, the fracture risk.
