The bottom wall of the installation cavity is provided with a first ventilation hole. The wind blown out by the first fan component flows to the cooling cavity through the first ventilation hole and is then discharged to the outside. A shock-absorbing gap is provided between the first fan component and the side wall of the installation cavity. The first sealing ring is provided between the first fan component and the bottom wall of the installation cavity to prevent the cold wind at the air outlet end of the first fan component from flowing to the shock-absorbing gap. The setting of the shock-absorbing gap can prevent the vibration generated by the operation of the first fan assembly from being directly transmitted to the side wall of the installation cavity, thereby reducing the noise generated by the vibration of the first fan assembly; in addition, the first sealing ring can also be used to block the cold air at the air outlet end of the first fan assembly from flowing to the shock-absorbing gap, thereby avoiding the loss of part of the cold air flowing to the air inlet side of the first fan assembly through the shock-absorbing gap and being discharged, that is, avoiding diversion and turbulence when the first fan assembly is working, thereby improving the air cooling efficiency; finally, since no cold air is discharged from the shock-absorbing gap, the wind noise is also reduced. It is measured by experiment: 1 cup of rice and 7 cups of water are cooked in the quick porridge cooking mode, from 45kPa to 0kPa, the pressure reduction time of the cooking utensil of the utility model is 6 minutes and 12 seconds, and the pressure reduction time is 8 minutes and 36 seconds without the first sealing ring, the noise is reduced from 63db to 60db, the sound quality is improved, and the wind noise is changed from sharp to soft, thereby improving the user experience.

[0018] 2. The first sealing ring surrounds the outside of the area where the first ventilation hole is provided on the bottom wall of the installation cavity, and the side wall is provided with a first air inlet hole located on the air inlet side of the first fan assembly. With this design, most of the cold air discharged by the first fan assembly can flow directly to the first ventilation hole and enter the cooling cavity, thereby reducing the flow path of most of the cold air and improving the cooling efficiency; in addition, it can also make the air intake of the entire air duct smoother.

[0022] 6. The first sealing ring is a flexible part. Such a design can not only improve the sealing effect of the damping gap and reduce the processing and assembly accuracy of each component, but also buffer the vibration of the first fan assembly when it is working, so that the vibration generated by the first fan assembly when it is running will not be directly transmitted to the wall of the installation cavity, thereby reducing mechanical noise.

[0023] 7.

With such a design, during the cooking process, the supporting cantilever will not directly contact the cooking environment in the pot body, so the oil smoke, water vapor and food residues in the pot will not reach the installation cavity and the first air inlet on the supporting cantilever, thereby ensuring the cleanliness of each component and reducing the cleaning pressure of the user.

[0024] 8.

[0025] 9. A fan bracket for fixing the second fan assembly is provided on the outside of the outer pot. The fan bracket has a side plate surrounding the outside of the second fan assembly.

This design can prevent the cold air discharged from the second fan assembly from leaking through the gap after diversion, thereby improving the air cooling efficiency and also avoiding the noise generated by leaking through the gap.

[0026] 10. The outer side of the outer pot is provided with a fan bracket for fixing the second fan assembly, and the inner side of the outer shell is provided with a wind shielding rib surrounding the outer side of the second air inlet and abutting against the fan bracket.

A shock-absorbing gap 340 is provided between the first fan assembly 330 and the side wall 324 of the installation cavity. The first sealing ring 310 is provided between the first fan assembly 330 and the bottom wall 323 of the installation cavity to prevent the cold wind at the air outlet end of the first fan assembly 330 from flowing to the shock-absorbing gap 340.

It is measured by experiment: 1 cup of rice and 7 cups of water are cooked in the fast porridge cooking mode, from 45kPa to 0kPa, the pressure reduction time of the cooking utensil of this embodiment is 6 minutes and 12 seconds, and the pressure reduction time is 8 minutes and 36 seconds without the first sealing ring, the noise is reduced from 63db to 60db, the sound quality is improved, and the wind noise is softened from sharp, thereby improving the user experience.

[0044] Specifically, Figure 2 , Figure 3 and Figure 7As shown, the cooking utensil in this embodiment also includes a supporting cantilever 400, which includes an upper cantilever shell 410 and a lower cantilever shell 420. The upper cantilever shell 410 and the lower cantilever shell 420 are connected so that the supporting cantilever 400 has an inner cavity. The upper cantilever shell 410 and the lower cantilever shell 420 both have a supporting end located on the outer peripheral side of the pot cover 200, and an operating end extending to the center of the pot cover 200. The supporting end can move relative to the pot body 100 so that the supporting cantilever 400 can move relative to the pot body 100 to be located above the pot cover 200 or moved away from above the pot cover 200 to leave a space for taking and placing the pot cover 200. The specific structure can refer to the prior art and will not be described in detail here. The end of the lower cantilever shell 420 corresponding to the center of the pot cover 200 and the end of the upper cantilever shell 410 corresponding to the center of the pot cover 200 cooperate to enclose the installation cavity 320, that is, the installation cavity 320 is located in the operating end, the first ventilation hole 322 is provided on the lower cantilever shell 420, and the inner cavity of the support cantilever 400 can facilitate the wiring of the wires of the first fan assembly 330. With such a design, during the cooking process, the support cantilever 400 will not directly contact the cooking environment in the pot body 100, so the oil smoke, water vapor and food residues in the pot will not reach the installation cavity 320 and the first air inlet 321 on the support cantilever 400, ensuring the cleanliness of each component and reducing the cleaning pressure of the user.

[0045] The surface cover 210 in this embodiment includes a main body 211 and a cover body 212 detachably mounted on the main body 211. The main body 211 is covered on the outside of the inner cover 220. An opening 2110 is provided at the center of the main body 211. The area of ​​the inner cover 220 corresponding to the opening 2110 is recessed toward the pot body 100 to form a positioning platform 221. The edge of the opening 2110 has a folded edge bent toward the inner cover 220. The inner cover 220 has a contact plane 222 surrounding the positioning platform 221, and the folded edge abuts against the contact plane 222. In addition, the edge of the opening 2110 is also provided with an installation position for installing the cover body 212. The outer peripheral side of the cover body 212 is provided with a sealing member. The cover body 212 is inserted into the opening 2110 by means of interference fit, so that the cover body 212 and the edge of the opening 2110 abut against the sealing member from both sides, thereby completing the detachable installation of the cover body 212 on the main body 211. At this time, the surface cover 210 cooperates with the inner cover 220 to form the cooling cavity 001. The cover body 212 is provided with a first air outlet 2120, so that the wind in the cooling cavity 001 flows to the outside through the first air outlet 2120. The installation method of the cover body 212 in this embodiment, on the one hand, reduces the difficulty of disassembly and assembly of the cover body 212. On the other hand, the two sides of the sealing member are squeezed by the edge of the opening 2110 and the peripheral side of the cover body 212 and deformed, forming a seal on the gap between the two, thereby ensuring the sealing performance of the connection.

[0046] The cover 212 is provided with a positioning opening 2121, and the portion of the lower cantilever shell 420 corresponding to the positioning opening 2121 is arched outward to form a positioning boss 421, and the positioning boss 421 forms a part of the wall of the installation cavity.

The first air inlet holes 321 are located above the cover 210. With such a design, most of the cold air discharged from the first fan assembly 330 can flow directly to the first ventilation holes 322 and enter the cooling cavity 001, thereby reducing the flow path of most of the cold air and improving the cooling efficiency; in addition, it can also make the air intake of the entire air duct smoother.

[0048] The bottom wall 323 in this embodiment is provided with a screw column, and the first fan assembly 330 is supported on the screw column and fixed to the screw column by fasteners (screws, bolts, etc.). At this time, the lower side of the first fan assembly 330 is the air outlet side, and the upper side of the first fan assembly 330 is the air inlet side. The first sealing ring 310 surrounds the outside of the area where the first ventilation hole 322 is provided on the bottom wall 323, and the first sealing ring 310 is clamped and fixed between the bottom wall 323 and the first fan assembly 330. Such a design allows the first sealing ring 310 to be set close to the first ventilation hole 322 to guide cold air to quickly enter the cooling chamber 001, thereby improving the cooling efficiency. In addition, the first fan assembly 330 can be fixed to the bottom wall 323 by fasteners, and the first sealing ring 310 can be assembled and fixed at the same time, thereby reducing the steps of the first heat dissipation assembly 300 and improving the assembly efficiency of the first heat dissipation assembly 300.

[0049] Preferably, the first sealing ring 310 in the present embodiment is provided with a through hole 312, and a fastener is arranged through the through hole 312, that is, the fastener sequentially passes through the first fan assembly 330 and the first sealing ring 310 and is locked with the screw column. With such a design, the first sealing ring 310 is fixed by the fastener, thereby further improving the installation reliability of the first sealing ring 310.

[0050] Preferably, the bottom wall 323 in the present embodiment has a positioning protrusion 3231 surrounding the outside of an area where the first ventilation hole 322 is provided on the bottom wall 323, and the positioning protrusion 3231 extends toward the first fan assembly 330, and the first sealing ring 310 is provided with a positioning groove 311, and the positioning groove 311 is plugged into and matched with the positioning protrusion 3231. With such a design, the first sealing ring 310 can be positioned through the cooperation between the positioning groove 311 and the positioning protrusion 3231 to prevent the first sealing ring 310 from shifting and causing the sealing of the shock-absorbing gap 340 to fail, thereby ensuring the sealing effect of the first sealing ring 310 on the shock-absorbing gap 340.

[0051] Preferably, the first sealing ring 310 in this embodiment is a flexible member, such as a silicone member or a rubber member. Such a design can not only improve the sealing effect of the damping gap 340 and reduce the processing and assembly accuracy of each component, but also buffer the vibration of the first fan assembly 330 when it is working, so that the vibration generated by the first fan assembly 330 when it is running will not be directly transmitted to the wall of the installation cavity, thereby reducing mechanical noise.

[0053] It can be understood that in other embodiments of the present invention, the first sealing ring can also be arranged between the side wall and the outer peripheral side of the first fan assembly, that is, the first sealing ring is clamped and fixed between the outer peripheral side of the first fan assembly and the side wall of the installation cavity. Such a design can achieve that the first sealing ring blocks the shock-absorbing gap to cut off the connection between the first ventilation hole and the first air inlet hole, avoid cold air leakage loss, thereby improving the cooling efficiency and reducing wind noise.

A second fan assembly 140 is provided between the outer pot 120 and the outer shell 130. The second fan assembly 140 is activated to inhale external air from the second air inlet hole 131 and blow it toward the second ventilation hole 121. With such a design, when the second fan assembly 140 is working, cold air from the outside enters the cooling air duct 101 through the second air inlet 131 and the second ventilation hole 121 to cool down the inner pot 110, thereby reducing the air pressure in the inner pot 110. Combined with the first heat dissipation assembly 300, the inner cover 220 is cooled, thereby making the pressure reduction speed faster to reduce the risk of steam scalding the user.

[0058] In order to improve the cooling and pressure reduction effect of the inner pot 110, a fan bracket 150 is provided on the outer side of the outer pot 120 in this embodiment, and the second fan assembly 140 is fixed to the side of the fan bracket 150 away from the outer pot 120 by fasteners. The fan bracket 150 has a bottom plate 151 located on the air outlet side of the second fan assembly 140 and a side plate 152 surrounding the outer side of the second fan assembly 140. The bottom plate 151 is provided with ventilation holes, and a second sealing ring 160 for sealing the gap between the side plate 152 and the side wall of the second fan assembly 140 is provided. The second sealing ring 160 includes a mounting ring 161 and a rib 162 which is arranged at one end of the mounting ring 161 and extends outwardly. The mounting ring 161 is mounted on the outside of the second fan assembly 140. The edge of the rib 162 extends to the outside of the side plate 152 and is sealed against the end surface of the side plate 152, so that the second sealing ring 160 blocks the gap between the second fan assembly 140 and the side plate 152, thereby preventing the cold air discharged from the second fan assembly from leaking through the gap after diversion, thereby improving the air cooling efficiency and also avoiding the noise generated by leakage through the gap.

[0059] Preferably, the shell 130 includes a shell body 1301 and an air inlet cover 132 clamped on the shell body, the air inlet cover 132 is provided with a plurality of the second air inlet holes 131, the air inlet cover 132 includes inwardly extending wind shielding ribs 1321, the wind shielding ribs 1321 surround all the second air inlet holes 131, and the wind shielding ribs 1321 are mounted on the outside of the mounting ring 161 to prevent cold air from leaking from the air inlet side of the second fan assembly 140.

[0060] Embodiment 2

[0061] like Fig. 9 As shown, compared with the first embodiment, the difference of this embodiment is that the wind shielding rib 1321 abuts against the end surface of the side plate 152, and the air outlet side of the second fan assembly 140 is closer to the outer pot 120 than the assembly gap between the wind shielding rib 1321 and the fan bracket 150 (i.e., the matching place between the end surface of the fan bracket 150 and the wind shielding rib 1321), that is, the distance between the air outlet side of the second fan assembly 140 and the bottom plate 151 is less than the height of the side plate 152. Such a design can prevent the cold air discharged from the second fan assembly 140 from leaking through the gap after diversion, thereby improving the air cooling efficiency, and also avoiding the noise generated by leaking through the gap; in addition, the second sealing ring can be omitted, thereby reducing the cost.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
