The sound-absorbing box 300 includes a box base 310, a box cover 320, and a sound-absorbing layer 330. Box base 310 is disposed close to pot body 100, and box cover 320 is covered on box base 310 and is far away from pot body 100. The sound absorbing layer 330 is disposed between the cabinet base 310 and the cabinet cover 320 and is made of a flexible sound absorbing material. The sound absorbing layer 330 includes a bottom wall 331 and a partition wall 332 disposed on the bottom wall 331, the bottom wall 331 is attached to the box cover 320, and the bottom wall 331, the partition wall 332 and the box holder 310 of the sound absorbing layer 330 together define the steam channel 400.

By applying the technical scheme of the embodiment, the cooking appliance comprises a pot body 100, a pot cover 200 and a sound absorption box 300. The sound-absorbing box 300 includes a box base 310, a box cover 320, and a sound-absorbing layer 330 disposed between the box base 310 and the box cover 320. The sound absorption layer 330 includes a bottom wall 331 attached to the box cover 320, and the bottom wall 331 is disposed in a manner that not only can the sound insulation and noise reduction effect be more effectively achieved, but also the heat insulation and temperature reduction effects can be achieved. Meanwhile, the sound absorption layer 330 is made of a flexible sound absorption material, so that all corners of the sound absorption layer 330 can be cleaned more easily, and food is prevented from being polluted by residual bacteria in the sound absorption layer 330. Therefore, the technical scheme of the embodiment solves the problems that the noise reduction device of the electric pressure cooker in the prior art is difficult to clean and the noise reduction effect is not good. The flexible sound absorbing material is a flexible material capable of absorbing sound.

Of course, as a practical implementation, the bottom wall 331 may also be attached to the box holder 310, and the steam channel 400 is defined by the partition wall 332, the bottom wall 331 and the box cover 320. Or the partition wall 332 and the cabinet base 310 and the cabinet cover 320 together enclose the steam passage 400.

The air inlet 311 and the air outlet 312 enable the steam to circulate between the sound absorption layer 330 and the pan body 100, thereby realizing the noise reduction function.

In order to prevent steam condensate from flowing back through the inlet 311, as shown in fig. 4, in the present embodiment, an inlet structure 313 communicating with the steam channel 400 is provided on the tank holder 310, and the inlet 311 is formed on the inlet structure 313. The air inlet structure 313 is a tubular structure with an opening, and specifically, the air inlet structure 313 comprises a top wall 313-1 and a side wall 313-2 connected with the top wall 313-1, and the side wall 313-2 is provided with air inlet holes 313-3. When the cooking appliance works, steam enters the steam channel 400 from the air inlets 313-3 on the side wall 313-2, and condensed water is blocked by the top wall 313-1 and cannot flow back due to the fact that the top wall 313-1 is arranged at the end part of the side wall 313-2.

Preferably, as shown in FIG. 4, the air intake holes 313-3 are located at the upper portion of the side wall 313-2. Thereby preventing the condensed water from flowing back through the air intake holes 313-3 when excessive accumulation occurs in the steam channel 400.

As shown in FIG. 4, in the solution of the present embodiment, there are a plurality of air intake holes 313-3, and the plurality of air intake holes 313-3 are evenly distributed on the side wall 313-2 along the circumferential direction. The steam is discharged into the steam channel through the plurality of air inlet holes 313-3, so that a certain noise reduction function can be realized, and the high-pressure steam can be buffered, so that the impact of the steam on the sound absorption layer 330 is relieved, and the service life of the sound absorption layer 330 is prolonged.

Preferably, the sound absorption layer 330 is made of silica gel. Adopt silica gel can fully cushion the pressure of steam, and then guarantee the noise reduction effect, silica gel is comparatively soft simultaneously can the person of facilitating the use wash to sound absorbing layer 330. Besides the silicone rubber as the flexible sound-absorbing material, the sound-absorbing layer 330 can also be made of other flexible sound-absorbing materials, such as sound-absorbing cotton.

As shown in fig. 9, in the solution of the present embodiment, the box base 310 and the box cover 320 are detachably connected together. Specifically, the base 310 and the lid 320 are connected together by a snap and a buckle. The connection between the box base 310 and the box cover 320 is not limited to this, and other connection methods such as a threaded connection may be used, and the specific connection method may be selected according to the actual structure.

The base 310 and cover 320 are removably coupled together to facilitate easy removal of the sound-absorbing layer 330, thereby facilitating cleaning of the sound-absorbing layer by a user.

As shown in fig. 10 and 12, in the present embodiment, the partition wall 332 includes a first partition wall 332-1. The sound absorbing layer 330 is partitioned into a first noise reduction region 333 and a second noise reduction region 334 at least partially surrounding the outside of the first noise reduction region 333 by a first partition wall 332-1, and a notch 332-11 communicating the first noise reduction region 333 and the second noise reduction region 334 is provided in the first partition wall 332-1. In the solution of the present embodiment, the air inlet 311 is communicated with the first noise reduction region 333, and the air outlet 312 is communicated with the second noise reduction region 334.

The steam enters the first noise reduction region 333 through the air inlet 311 and then is subjected to primary buffering and noise reduction, and then enters the second noise reduction region 334 through the notches 332-11. The second noise reduction region 334 at least partially surrounds the first noise reduction region 333 and is bent, so that the flow distance of steam can be prolonged, the energy of steam can be reduced, and a better steam noise reduction function can be realized. The steam finally flows back into the pot body 100 from the air outlet 312. It should be noted that the first noise reduction region 333 and the second noise reduction region 334 together form the steam channel 400. In the solution of the present embodiment, the flow direction of the steam is as shown by the arrow in fig. 11, the steam enters the first noise reduction region 333 through the air inlet 311, and then enters the second noise reduction region 334 through the notches 332-11, and finally exits through the air outlet 312.

Preferably, a noise reduction channel 334-1 is disposed in the second noise reduction region 334, the noise reduction channel 334-1 is bent, and the flow distance of steam is further extended by disposing the noise reduction channel 334-1, so as to enhance the noise reduction effect of the sound absorption box 300.

As shown in fig. 11, the notch 332-11 is located between the air inlet 311 and the air outlet 312, and preferably, the notch 332-11, the air inlet 311 and the air outlet 312 are located on a straight line, thereby increasing the flow distance of the steam and increasing the noise reduction effect.

As shown in fig. 12 and 13, the sound absorbing layer 330 further includes an annular side wall 335 provided on the peripheral edge of the bottom wall 331. The first partition wall 332-1 includes two first plates 332-12 and a second plate 332-13, the two first plates 332-12 being disposed opposite to each other, and a first end of each first plate 332-12 being coupled to the annular side wall 335. The second plate 332-13 is connected between the second ends of the two first plates 332-12. The first noise reduction region 333 is defined by the first plate body 332-12, the second plate body 332-13 and the annular side wall 335 as a wider square region (compared to the noise reduction passage 334-1), and pressure is released when high-pressure steam enters the first noise reduction region 333, so that preliminary noise reduction is realized.

Preferably, the notch 332-11 is provided on the second plate 332-13, and the notch 332-11 is located at the middle of the second plate 332-13. The structure enables the sound absorption box to be stressed uniformly.

As shown in fig. 12 and 13, the partition wall 332 further includes a second partition wall 332-2. The second partition wall 332-2 includes two third plate bodies 332-21 and one fourth plate body 332-22. Wherein the two third plates 332-21 are respectively disposed at a side of the two first plates 332-12 away from the first noise reduction region 333, and the fourth plates 332-22 are connected between first ends of the two third plates 332-21. Wherein a flow passage 337 is formed between the second end of each third plate body 332-21 and the annular side wall 335. The second noise reduction area 334 is divided into two bent noise reduction channels 334-1 by the arrangement mode of the third plate body 332-21 and the fourth plate body 332-22, the flow distance of steam in the second noise reduction area 334 is greatly prolonged, and a better noise reduction effect is achieved.

As shown in fig. 14 and 15, in the solution of the present embodiment, a spoiler 500 is disposed inside the noise reduction channel 334-1. When the steam flows into the baffle 500, the baffle 500 can absorb the energy of the steam and slow down the flow velocity of the steam. Therefore, the noise reduction effect of the sound absorption box can be greatly improved by the spoiler 500.

In order to facilitate manufacturing and ensure a noise reduction effect, in the technical solution of this embodiment, the spoiler 500 and the sound absorbing layer 330 are an integral structure.

As shown in FIG. 14, the spoiler 500 is attached to both the bottom wall 331 and the side walls of the noise reduction channel 334-1, thereby allowing the spoiler 500 to support the side walls of the noise reduction channel 334-1. Gaps are formed between the spoiler 500 and the side walls of the noise reduction passage 334-1 at positions close to the cabinet base 310, and part of the steam can flow through the spoiler 500 along the gaps, thereby preventing the sound absorbing layer 330 from being damaged by excessive impact force of the high-pressure steam on the spoiler 500.

As shown in fig. 16-18, a gap is formed between the substructure and the sidewall of noise reduction channel 334-1. When steam flows through the lower structure, the lower structure inclines towards one side and absorbs the energy of the steam, and then the noise reduction effect is achieved.

As shown in fig. 16 to 18, the spoiler includes a support part 520 and a spoiler 530. The support portion 520 is disposed on the bottom wall 331, both ends of the support portion 520 are connected to the side walls of the noise reduction duct 334-1, and the support portion 520 has a first blocking surface 521. The choke portion 530 is connected to an end of the support portion 520 away from the bottom wall 331, and the choke portion 530 forms a lower structure. The choke portion 530 has a second choke surface 531, and the width of the second choke surface 531 is smaller than the width of the first choke surface 521.

As shown in fig. 17 and 18, in the solution of the present embodiment, in order to facilitate the mold manufacturing, the thickness of the flow resisting portion 530 is smaller than that of the supporting portion 520.

As shown in fig. 12 and 13, in the solution of the present embodiment, there are a plurality of spoilers 500. The high-pressure steam sequentially passes through the plurality of spoilers 500 to achieve the effect of continuously reducing pressure and speed, and further the noise reduction effect of the sound absorption box 300 is greatly improved.

Preferably, the spoiler 500 is made of silica gel, so that the noise reduction effect is guaranteed and the spoiler is easy to clean.
