Description

[Technical field]

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a cooking utensil. [Background technology]

[0002] The existing cooking utensil includes an inner pot 01, an outer pot 02 for accommodating the inner pot, and an outer shell 03 arranged on the outside of the outer pot 02. The outer shell 03 is provided with an outer air inlet and an outer air outlet. The side wall of the outer pot is provided with an inner air inlet corresponding to the outer air inlet and an inner air outlet corresponding to the outer air outlet. Cold air from the outside can enter between the outer pot and the inner pot through the outer air inlet and the inner air inlet. After the cold air exchanges heat with the inner pot and absorbs heat, it is discharged from the inner air outlet and the outer air outlet to cool the inner pot and ensure the effect of the water-moistening film technology. The existing outer pot 02 is also provided with a protective frame 04 for allowing air to pass through at the inner air inlet and the inner air outlet. The protective frame 04 can prevent foreign objects such as reptiles from entering the outer pot. Both sides of the existing protective frame 04 are fixed to the side wall of the outer pot by screws. The side wall of the outer pot is provided with a countersunk hole 020, such as Figure 1 and 2 As shown, since the locking directions of the screws on both sides are set in parallel, the countersunk hole 020 on the outer pot 02 is a larger elliptical cone, and the size defect rate of the countersunk hole 020 is high during stamping; at the same time, when the screws are locked, the guiding of the elliptical cone countersunk hole is poor, and the locking screws are easily skewed, causing them to exceed the inner side of the outer pot, which not only affects the assembly efficiency, but also affects the appearance and interferes with the removal and placement of the inner pot.

[0009] In the above cooking utensil, the protective frame is provided with a positioning groove, and the wall portion of the countersunk hole is at least partially located in the positioning groove.

[0010] In the above cooking appliance, the portion of the fastener located inside the outer pot is located in the countersunk hole.

[0011] In the above-mentioned cooking appliance, two external vents are provided on the outer shell, one of which forms an external air inlet and the other forms an external air outlet. The side wall of the outer pot is provided with two internal vents, which correspond to the two external vents respectively. The fan is installed on at least one of the protective frames.

[0012] In the above cooking appliance, the fan is installed on a protective frame corresponding to the external air inlet, and an air inlet net is provided between the protective frame and the side wall of the outer pot.

[0013] In the above cooking appliance, the fan is fixed to the protective frame through a shock-absorbing pad, one of the shock-absorbing pad and the protective frame is provided with a fixing column, and the other of the two is provided with a fixing hole, and the fixing column passes through the fixing hole and is fixed.

[0014] In the above cooking appliance, the two inner vents are arranged on opposite sides of the outer pot.

[0015] Beneficial effects of the utility model:

[0016] 1. In the utility model, the side wall of the outer pot is provided with a countersunk hole that is recessed outward, and the center line of the countersunk hole extends along the radial direction of the outer pot. The fastener passes through the countersunk hole and is locked and fixed with the protective frame. With such a design, the portion where the countersunk hole and the head of the fastener are adapted can be a standard circle, thereby making the punched countersunk hole smaller, the material flow is uniform during punching and forming, the processing and forming is simple, and the product yield is high; in addition, when the fastener is locked, the guiding effect and stability of the countersunk hole on the head of the fastener can be improved, so that the fastener is not easily skewed when connected, and the assembly efficiency is high while ensuring a beautiful appearance.

[0017] 2. The countersunk hole is a conical countersunk hole, and the fastener is a countersunk screw. This design can improve the fit between the countersunk hole and the countersunk screw, thereby improving the guiding effect of the fastener and improving assembly efficiency; in addition, it can also reduce the difficulty of stamping processing of the countersunk hole to further improve the yield rate.

[0018] 3. Two countersunk holes are symmetrically arranged on both sides of the inner vent, and the two countersunk holes are spaced along the circumference of the outer pot. Such a design can not only improve the connection reliability of the protective frame, but also provide operating space for the assembly of fasteners, thereby reducing the difficulty of fastener assembly.

[0019] 4. The protective frame is provided with a positioning groove, and the wall of the countersunk hole is at least partially located in the positioning groove. With such a design, the protective frame can be pre-positioned through the cooperation between the wall of the countersunk hole and the positioning groove, so as to facilitate the subsequent locking of the fastener and the protective frame, thereby reducing the difficulty of assembling the protective frame.

[0020] 5. The part of the fastener located on the inner side of the outer pot is located in the countersunk hole. This design can prevent the fastener from exceeding the inner circumference of the outer pot and interfering with the inner pot, causing the inner pot to be unable to be placed in the outer pot. At the same time, this design also improves the appearance of the inner circumference of the outer pot.

[0021] 6. The outer shell is provided with two external vents, one of which forms an external air inlet and the other forms an external air outlet. The side wall of the outer pot is provided with two internal vents, which correspond to the two external vents respectively, and the fan is installed on at least one of the protective frames. With such a design, the protective frame can provide a mounting position for the fan, and there is no need to set an additional mounting position on the outer pot or the outer shell to fix the fan, thereby simplifying the structural difficulty of the outer pot and the outer shell.

[0022] 7. The fan is installed on the protective frame at the corresponding external air inlet. An air inlet net is also provided between the protective frame and the side wall of the outer pot. The air inlet net covers the internal vents. The fasteners penetrate the countersunk holes and the air inlet net and the protective frame to lock and fix them. With this design, the air inlet net can prevent foreign objects from entering. At this time, the air holes on the protective frame can be set larger so that the air discharged by the fan can quickly pass through the protective frame to the air inlet net, thereby improving the cooling efficiency.

[0023] 8. The fan is fixed to the protective frame through a shock-absorbing pad. One of the shock-absorbing pad and the protective frame is provided with a fixing column, and the other is provided with a fixing hole. The fixing column passes through the fixing hole and is fixed. This design avoids any hard contact between the fan and the protective frame. When the fan is working, the vibration of the fan will be absorbed by the shock-absorbing pad, thereby preventing the vibration of the fan from being transmitted to the protective frame, and thus avoiding the resonance of the protective frame, thereby greatly reducing noise; in addition, the shock-absorbing pad and the protective frame are connected and fixed by the fixing column and the fixing hole, which not only saves the screw fixation, reduces the difficulty of assembling the shock-absorbing pad and the protective frame, but also ensures the firmness of the connection between the shock-absorbing pad and the protective frame, thereby preventing the shock-absorbing pad from falling off the protective frame.

[0024] 9. Two inner vents are arranged on opposite sides of the outer pot. This design can extend the flow path of the wind between the outer pot and the inner pot to improve the heat dissipation effect of the inner pot.

[0025] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0038] Embodiment 1

[0039] like Figures 3 to 6 As shown, the cooking utensil in this embodiment includes a pot body and a pot cover, wherein the pot body includes an inner pot 100, an outer pot 200 and an outer shell 300, wherein the inner pot 100 is accommodated in the outer pot 200, and the outer shell 300 is arranged on the outer side of the outer pot 200, an outer vent 310 is provided on the outer shell 300, and an inner vent 210 and a protective frame 220 covering the inner vent 210 and allowing wind to pass through are provided on the side wall of the outer pot 200, a fan 400 is provided between the outer pot 200 and the outer shell 300 for promoting external cold air to flow to the inner pot 100 through the outer vent 310, the protective frame 220 and the inner vent 210, and the side wall of the outer pot 200 is provided with an outwardly recessed countersunk hole 230, the center line O of the countersunk hole 230 extends along the radial direction of the outer pot 200, and the fastener 500 passes through the countersunk hole 230 and is locked and fixed with the protective frame 220. Such a design can make the portion where the countersunk hole 230 and the head of the fastener 500 fit into a standard circle, thereby making the stamped countersunk hole smaller, the material flow being even during stamping, the processing being simple, and the product yield being high; in addition, when the fastener 500 is locked, the guiding effect and stability of the countersunk hole 230 on the head of the fastener 500 can also be improved, making it less likely for the fastener 500 to tilt when connected, thereby ensuring high assembly efficiency and beautiful appearance.

[0040] Specifically, the countersunk hole 230 in this embodiment is a conical countersunk hole, and the fastener 500 is a countersunk screw. The center line O of the countersunk hole 230 extends along the radial direction of the outer pot 200, which means that the center line of the conical countersunk hole extends horizontally and intersects with the center line of the outer pot 200. Such a design can improve the fit between the countersunk hole 230 and the countersunk screw, thereby improving the guiding effect of the fastener 500 and improving the assembly efficiency; in addition, it can also reduce the difficulty of the stamping process of the countersunk hole 230 to further improve the yield rate.

[0041] In this embodiment, two countersunk holes 230 are respectively provided on the sides of each inner vent 210, and the two countersunk holes 230 are symmetrically arranged on both sides of the inner vent 210, and the two countersunk holes 230 are spaced apart along the circumference of the outer pot 200. Such a design can not only improve the connection reliability of the protection frame 220, but also provide an operating space for the assembly of the fastener 500, so as to reduce the difficulty of assembling the fastener 500.

[0042] In order to reduce the difficulty of assembling the protection frame 220, in this embodiment, the protection frame 220 is provided with a positioning groove 221, and the wall of the countersunk hole 230 is at least partially located in the positioning groove 221. With such a design, the protection frame 220 can be pre-positioned through the cooperation between the wall of the countersunk hole 230 and the positioning groove 221, so as to facilitate the subsequent locking of the fastener 500 and the protection frame 220, thereby reducing the difficulty of assembling the protection frame 220.

[0043] In addition, the portion of the fastener 500 located on the inner side of the outer pot (i.e., the head of the fastener 500) in this embodiment is completely located in the countersunk hole 230. This design can prevent the fastener 500 from exceeding the inner circumference of the outer pot 200 and interfering with the inner pot 100, so that the inner pot 100 cannot be placed in the outer pot 200. At the same time, this design also improves the appearance of the inner circumference of the outer pot 200.

[0044] In addition, in this embodiment, two outer vents 310 are provided at intervals in the circumferential direction on the side wall of the shell 300, one of which forms an outer air inlet and the other forms an outer air outlet. Two inner vents 210 are provided on the side wall of the outer pot 200, and the two inner vents 210 correspond to the two outer vents 310 respectively. Protective frames 220 are installed at the two inner vents 210 through fasteners 500, respectively. The fan 400 is installed on the protective frame 220 corresponding to the outer air inlet, that is, the fan 400 is installed on the protective frame 220 at the inner vent 210 corresponding to the outer air inlet, and the protective frame 220 at the other inner vent 210 is an air outlet net. With such a design, the protective frame 220 can provide a mounting position for the fan 400, and there is no need to set an additional mounting position on the outer pot 200 or the shell 300 to fix the fan 400, thereby simplifying the structural difficulty of the outer pot 200 and the shell 300. When the fan 400 is working, it draws in cold air from the outside and discharges it toward the protective frame 220, and then enters between the inner pot 100 and the outer pot 200 through the external air inlet and the internal ventilation port 210. After the cold air from the outside absorbs the heat of the inner pot 100, it is discharged from the pot body through another internal ventilation port 210 and the external air port to achieve cooling of the inner pot 100. In addition, setting up a fan 400 can also reduce the manufacturing cost of the pot body.

[0045] In addition, in this embodiment, an air inlet net 240 is provided between the protective frame 220 and the side wall of the outer pot 200. The air inlet net 240 covers the inner vent, and the fastener 500 penetrates the countersunk hole 230 and the air inlet net 240 and is locked and fixed to the protective frame 220. With such a design, the air inlet net 240 can prevent foreign matter from entering. At this time, the air holes on the protective frame 220 can be set larger so that the wind discharged by the fan 400 can quickly pass through the protective frame 220 and flow to the air inlet net 240, thereby improving the cooling efficiency.

[0046] In order to extend the flow path of the wind between the outer pot 200 and the inner pot 100, the two inner vents 210 in this embodiment are arranged on opposite sides of the outer pot 200. With such a design, the flow path of the wind between the outer pot 200 and the inner pot 100 can be extended by increasing the distance between the two inner vents 210, thereby increasing the contact time between the wind and the inner pot 100, thereby improving the heat dissipation effect of the inner pot 100.

[0047] In order to reduce the noise of the fan 400 when it is working, the fan 400 in this embodiment is fixed to the protective frame 220 through a shock-absorbing pad 600. The shock-absorbing pad 600 is made of a flexible material such as silicone or rubber. The shock-absorbing pad 600 includes a body 610 and a fixing column 620. The body 610 is sleeved on the outside of the fan 400, and part of the body 610 is clamped between the protective frame 220 and the fan 400. The fixing column 620 is arranged on the body 610 and extends toward the protective frame 220. The protective frame 220 is provided with a fixing hole, and the fixing column 620 passes through the fixing hole and is fixed. Such a design avoids the fan 400 and the protective frame 220 from vibrating. Any hard contact is produced. When the fan 400 is working, the vibration of the fan 400 will be absorbed by the shock-absorbing pad 600, thereby preventing the vibration of the fan 400 from being transmitted to the protective frame 220, and also avoiding the resonance of the protective frame 220, thereby greatly reducing the noise; in addition, the shock-absorbing pad 600 and the protective frame 220 are connected and fixed by the fixing column 620 and the fixing hole, which not only eliminates the need for screw fixation and reduces the difficulty of assembling the shock-absorbing pad 600 and the protective frame 220, but also ensures the firmness of the connection between the shock-absorbing pad 600 and the protective frame 220, thereby preventing the shock-absorbing pad 600 from falling off the protective frame 220.

[0048] In order to enable the fixing column 620 to pass through the fixing hole and be fixed, the fixing column 620 in this embodiment includes an anti-slip section 621 and a matching section 622 that passes through the fixing hole, the matching section 622 is connected between the anti-slip section 621 and the main body 610, the outer diameter of the matching section 622 is smaller than the aperture of the fixing hole, and the outer peripheral surface of the anti-slip section 621 is a conical surface that gradually shrinks away from the matching section, the maximum outer diameter of the conical surface is larger than the aperture of the fixing hole, and the minimum outer diameter of the conical surface is smaller than the aperture of the fixing hole. With such a design, the fixing column 620 can pass through the fixing hole smoothly through the guidance of the outer peripheral surface of the anti-slip section 621, and after the matching section 622 is matched with the fixing hole, the fixing column 620 can be fixed to the protective frame 220 through the anti-slip section 621, and the assembly is simple and convenient.

[0049] It is understandable that in other embodiments of the utility model, the fixing column can also be integrally formed on the protective frame, and the shock-absorbing pad is provided with a fixing hole. The structure of the fixing column can be set with reference to the above embodiment. Such a design can realize that the fixing column passes through the fixing hole and is fixed to the shock-absorbing pad.

[0050] It can be understood that in other embodiments of the present invention, there are two external vents and one internal vent, and one external vent corresponds to the internal vent, so that the outside cold air enters the outer pot through the external vent, the protective frame and the internal vent under the action of the fan and flows to the inner pot. At this time, an air outlet gap is formed between the edge of the outer pot and the edge of the inner pot, so that the heat-absorbing wind is discharged to the outside of the outer pot and discharged to the outside of the pot body through another external vent.

[0051] It can be understood that in other embodiments of the present invention, the number of external vents and internal vents is one, and the external vents correspond to the internal vents. Under the action of the fan, cold air from the outside enters the outer pot through the external vents, the protective frame and the internal vents and flows toward the inner pot. At this time, an air outlet gap is formed between the edge of the outer pot and the edge of the inner pot, so that the heat-absorbing air is discharged to the outside of the outer pot, and then discharged through the gap between the pot cover and the pot body.

[0052] It is understandable that in other embodiments of the present invention, the fan may also be installed on a protective frame corresponding to the external air outlet, and in this case, the protective frame corresponding to the external air inlet is an air inlet net.

[0053] It can be understood that in other embodiments of the present invention, the number of fans is two, one is installed on the protective frame corresponding to the external air inlet, and the other is installed on the protective frame corresponding to the external air outlet.

[0054] It can be understood that in other embodiments of the present invention, the countersunk hole is a cylindrical countersunk hole, and the fastener is a flat head screw.

[0055] 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.
