Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a cooking appliance. Background Art

[0002] Some cooking appliances (such as rice cookers, electric pressure cookers, etc.) are provided with cooling fans on the pot body. By controlling the cooling fans to blow cold air into the inner part of the pot body and outside the inner liner at different cooking stages, effects such as accelerating the cooling of the inner liner, reducing pressure by air cooling, or achieving non-sticking of the inner liner can be achieved.

[0003] The air source of the cooling fan comes from the outside. Therefore, the pot body usually has an air inlet at the position corresponding to the cooling fan on the outer shell. And in order to improve the aesthetics and prevent foreign impurities from entering the inner part of the pot body, an air inlet cover is fixed at the air inlet.

[0004] The common fixing methods of the air inlet cover and the pot body generally include screw fixing and snap fixing. Among them, the screw fixing method not only requires the assembler to manually tighten multiple screws, resulting in relatively low assembly efficiency, but also the screw heads will be exposed on the outer surface of the pot body, causing appearance defects and affecting the overall aesthetics of the machine. The snap fixing method requires processing snap joints for clamping on the pot body and the air inlet cover respectively. On the one hand, it increases the processing and manufacturing difficulty and cost. On the other hand, affected by the processing error, there will be a deviation in the relative position between the snap of the air inlet cover and the snap of the pot body, and then it may occur that the two cannot be snap-fitted, or the snap is not tight and the air inlet cover is prone to shaking. Content of the Utility Model

[0005] The utility model provides a cooking appliance to solve the problems of complex assembly of the air inlet cover and the pot body, low assembly efficiency, and easy shaking of the air inlet cover after assembly.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A cooking appliance includes a pot body and a cooling fan arranged inside the pot body. The pot body includes an outer cover, and the outer cover is provided with an installation opening. The cooking appliance further includes an air inlet cover arranged at the installation opening. The air inlet cover has an air inlet to enable outside air flow to reach the cooling fan through the air inlet. At least two sides of the installation opening are provided with fixing ribs, and the fixing ribs extend towards the inside of the outer cover to form a guiding part. The guiding part extends obliquely towards the inside of the installation opening to form a clamping part, and the clamping part clamps and fixes the air inlet cover.

[0008] The cooking appliance of the utility model further has the following additional technical features:

[0009] The edge of the installation opening bends towards the inside of the outer cover to form a flanging, and the flanging constitutes the fixing rib.

[0010] The fixing rib positions are arranged on two opposite sides of the installation opening; alternatively, the fixing rib positions are in multiple segments and are arranged along the circumferential direction of the installation opening, and there is a clearance groove between adjacent two segments of the fixing rib positions.

[0011] The outer wall of the outer cover is provided with an installation sunk platform that recesses inward, and the installation opening is located within the installation sunk platform, so that at least part of the air inlet cover is accommodated within the installation sunk platform.

[0012] The air inlet cover includes a cover body and an installation rib that extends towards the inside of the pot body. There is a step surface between the cover body and the installation rib. The step surface can abut against the bottom wall of the installation sunk platform so that the cover body is located within the installation sunk platform. The installation rib passes through the installation opening to abut and cooperate with the fixing rib position. The length of the installation rib is greater than the length of the clamping portion in the radial direction of the pot body.

[0013] The fixing rib position has a fixed end connected to the outer cover and a free end extending into the installation opening. The free end can swing around the fixed end under the pushing action of the air inlet cover and clamp the air inlet cover under its own elastic force.

[0014] The thickness of the free end is less than the thickness of the fixed end.

[0015] A transition curved surface is provided on the side of the free end facing the air inlet cover.

[0016] The air inlet cover is provided with a shielding rib that protrudes radially outward along the installation opening. The shielding rib is located outside the outer cover to shield the gap between the air inlet cover and the outer cover.

[0017] The outer cover includes a housing that surrounds the side of the pot body and a base that is located at the bottom of the pot body. The installation opening and the air inlet cover are provided on the housing and / or the base, and the cooling fan is provided corresponding to the air inlet cover.

[0018] Due to the adoption of the above technical solution, the beneficial effects obtained by the present utility model are as follows:

[0019] 1. In the present utility model, the outer cover is provided with an installation opening for installing the air inlet cover. At least two sides of the installation opening are provided with fixing rib positions. The fixing rib positions extend obliquely so that part of their areas are within the projection of the installation opening. When part of the structure of the air inlet cover extends into the installation opening, it forms a pushing force on the fixing rib positions, causing the fixing rib positions to expand outward under the extrusion force and clamp the air inlet cover under their own elastic force, realizing the clamping and fixing of the air inlet cover. Such a fixing method can not only save the use of additional fixing parts such as screws, simplify the structure and save costs, but also make the fixing of the air inlet cover not limited by the setting position of the fixing structure. Therefore, the influence of processing errors on the fixing stability of the air inlet cover can be eliminated. In addition, when installing the air inlet cover, only need to align the air inlet cover with the installation opening and push the air inlet cover towards the inside of the pot body. Once the air inlet cover forms an extrusion on the fixing rib positions, the fixing rib positions can clamp the air inlet cover, thus greatly reducing the assembly difficulty and improving the assembly efficiency.

[0020] Moreover, the fixed rib extends towards the inside of the installation opening, so that in the direction of the air inlet cover moving towards the inside of the pot body, the fixed rib can be pushed to expand outwards, thus enabling the fixed rib to play a certain role in avoiding the installation of the air inlet cover. The resistance during assembly is small, and the feel of the operator during operation is smoother. When the air inlet cover moves in the opposite direction, the inward contraction of the fixed rib will hinder the movement of the air inlet cover, thus firmly clamping the air inlet cover and preventing it from coming out of the installation opening, thereby ensuring the fixing stability of the air inlet cover.

[0021] 2. As a preferred embodiment of the present utility model, the edge of the installation opening is bent towards the inside of the outer cover to form a flanging, and the flanging constitutes the fixed rib. The edge of the installation opening is bent to form the fixed rib. On the one hand, it can improve the structural strength at the edge of the installation opening and prevent the installation opening from deforming. On the other hand, the operator can directly see the position where the fixed rib is located, playing a role in assembly reminder. At the same time, it can reduce the position error between the air inlet cover and the fixed rib, ensuring that after the air inlet cover extends from the installation opening, it can form extrusion and pushing against the fixed rib, avoiding the problem that the distance between the two is too large to effectively cooperate.

[0022] 3. As a preferred embodiment of the present utility model, the fixed rib is in multiple segments and is arranged along the circumference of the installation opening, and there is a clearance groove between adjacent two segments of the fixed rib. The fixed rib surrounds the installation opening, and can form clamping and fixing in multiple circumferential areas of the air inlet cover, thus not only further improving the fixing stability of the air inlet cover, but also being able to limit the air inlet cover to prevent it from shifting under the extrusion effect. At the same time, the clearance groove between the fixed ribs improves the ability of the fixed rib to elastically deform, enabling it to more easily elastically deform when pushed by the air inlet cover, thereby reducing the frictional resistance between the two during the assembly process, making the installation of the air inlet cover more labor-saving and improving the assembly experience.

[0023] 4. As a preferred embodiment of the present utility model, an installation sink is arranged on the outer wall of the outer cover and is recessed inward, and the installation opening is located in the installation sink, so that at least part of the area of the air inlet cover is accommodated in the installation sink. The installation sink can play a role in receiving and accommodating at least part of the area of the air inlet cover, enabling at least part of the area of the air inlet cover to be accommodated in the installation sink, and further enabling the outer surface of the air inlet cover to be as flush as possible with the outer surface of the outer cover, reducing the step difference between the two, avoiding the air inlet cover protruding too much from the surface of the outer cover, and ensuring the appearance quality and feel of the cooking appliance. At the same time, the installation sink can limit the air inlet cover and confine the air inlet cover in the installation sink, making the position of the air inlet cover more stable.

[0024] 5. As a preferred embodiment of the present utility model, the thickness of the free end is less than that of the fixed end. The smaller thickness of the fixed end can improve the structural strength on the basis of ensuring elastic deformation, avoid fracture when subjected to a large extrusion force from the air inlet cover, and can provide a large clamping force to the air inlet cover, improving the fixing stability of the air inlet cover. The free end contacts the air inlet cover and has a smaller thickness, which can ensure a stable clamping force on the air inlet cover and reduce the frictional force when the air inlet cover moves relative to the free end, making the assembly operation smoother and improving the assembly efficiency.

[0040] Such as Figure 1 , Figure 2 , Figure 3As shown in the figure, a cooking appliance includes a pot body 1 and a cooling fan disposed inside the pot body 1. The pot body 1 includes an outer cover 11, and the outer cover 11 is provided with an installation opening 12. The cooking appliance further includes an air inlet cover 2 disposed at the installation opening 12. The air inlet cover 2 has an air inlet 21 to enable external air flow to reach the cooling fan through the air inlet 21. At least two sides of the installation opening 12 are provided with fixing ribs 121. The fixing ribs 121 extend toward the inside of the outer cover 11 to form a guiding portion, and the guiding portion extends obliquely toward the inside of the installation opening 12 to form a clamping portion. The clamping portion clamps and fixes the air inlet cover 2.

[0041] In the present utility model, the outer cover 11 is provided with an installation opening 12 for installing the air inlet cover 2. At least two sides of the installation opening 12 are provided with fixing ribs 121. The fixing ribs 121 extend obliquely so that a partial area thereof is located within the projection of the installation opening 12. When a partial structure of the air inlet cover 2 extends into the installation opening 12, it pushes against the fixing ribs 121, causing the fixing ribs 121 to expand outward under the extrusion force and clamp the air inlet cover 2 under the action of its own elastic force, thereby realizing the clamping and fixing of the air inlet cover 2. Such a fixing method can not only save the use of additional fixing parts such as screws, simplify the structure and save costs, but also make the fixing of the air inlet cover 2 not limited by the setting position of the fixing structure, so as to eliminate the influence of processing errors on the fixing stability of the air inlet cover 2. In addition, when installing the air inlet cover 2, only need to align the air inlet cover 2 with the installation opening 12 and push the air inlet cover 2 into the pot body 1. Once the air inlet cover 2 exerts extrusion on the fixing ribs 121, the fixing ribs 121 can clamp the air inlet cover 2, thus greatly reducing the assembly difficulty and improving the assembly efficiency.

[0042] Moreover, the fixing ribs 121 extend toward the inside of the installation opening 12, so that in the direction of the air inlet cover 2 moving toward the inside of the pot body 1, it can push the fixing ribs 121 to expand outward, so that the fixing ribs 121 play a certain role in avoiding the installation of the air inlet cover 2, and the resistance during assembly is small, and the feel of the operator during operation is also smoother. When the air inlet cover 2 moves in the opposite direction, the fixing ribs 121 contract inward to hinder the movement of the air inlet cover 2, thereby firmly clamping the air inlet cover 2 so that it cannot be disengaged from the installation opening 12, thus ensuring the fixing stability of the air inlet cover 2.

[0043] It can be understood that the fixing ribs 121 can elastically deform, deform when pushed by the air inlet cover 2, and clamp the air inlet cover 2 under the action of its own elastic force. Specifically, as Figure 4 shown, the fixing ribs 121 have a fixed end 1211 connected to the outer cover 11 and a free end 1212 extending into the installation opening 12. The free end 1212 can swing around the fixed end 1211 under the pushing action of the air inlet cover 2 and clamp the air inlet cover 2 under the action of its own elastic force.

[0044] Since the free end 1212 is located inside the installation opening 12, when the air inlet cover 2 extends into the installation opening 12, it will inevitably interfere with the free end 1212, thereby pushing the fixed rib 121 to deform.

[0045] Specifically, during assembly, first align the air inlet cover 2 with the installation opening 12, and then push the air inlet cover 2 radially inward along the pot body 1 so that a partial area of the air inlet cover 2 is inserted into the installation opening 12. During this process, the air inlet cover 2 abuts against the free end 1212 of the fixed rib 121 and pushes the fixed rib 121 to deform outward, and clamps the air inlet cover 2 under the action of its own elastic force.

[0046] Furthermore, the thickness of the free end 1212 is less than the thickness of the fixed end 1211.

[0047] The thickness of the fixed end 1211 is small. On the basis of ensuring elastic deformation, the structural strength is improved to avoid fracture when receiving a large extrusion force from the air inlet cover 2, and it can provide a large clamping force for the air inlet cover 2 to improve the fixing stability of the air inlet cover 2. The free end 1212 contacts the air inlet cover 2 and has a small thickness, which can ensure a stable clamping force for the air inlet cover 2, and the frictional force received when the air inlet cover 2 and the free end 1212 move relative to each other makes the assembly operation smoother and improves the assembly efficiency.

[0048] Specifically, the thickness of the fixed rib 121 gradually decreases from the fixed end 1211 to the free end 1212.

[0049] Preferably, a transition curve surface is provided on the side of the free end 1212 facing the air inlet cover 2.

[0050] During the assembly process, once the air inlet cover 2 abuts against the fixed rib 121, the fixed rib 121 will form an inward clamping force on the air inlet cover 2. At this time, the air inlet cover 2 may not be installed in place yet, and the assembler needs to continue to push the air inlet cover 2 into the pot body 1. During this process, since the fixed rib 121 abuts against the air inlet cover 2, the assembler will receive a large frictional resistance when pushing the air inlet cover 2 inward. By providing a transition curve surface on the free end 1212, the contact between the fixed rib 121 and the air inlet cover 2 becomes softer. On the one hand, the frictional resistance between the two is reduced, making the assembler's operation smoother and more labor-saving. On the other hand, the wear between the two can be slowed down, and damage to the fixed rib 121 and the air inlet cover 2 can be avoided.

[0051] As a preferred embodiment of the present invention, as Figure 4 shown, the edge of the installation opening 12 bends inward toward the inside of the outer cover 11 to form a flanging, and the flanging constitutes the fixed rib 121.

[0052] The edge of the installation opening 12 is bent to form a fixed rib position 121. On the one hand, it can improve the structural strength at the edge of the installation opening 12 and prevent the installation opening 12 from deforming. On the other hand, the assembler can directly see the position where the fixed rib position 121 is located, which plays a role in assembly prompting. At the same time, it can reduce the positional error between the air inlet cover 2 and the fixed rib position 121, ensuring that after the air inlet cover 2 extends from the installation opening 12, it can form extrusion and pushing against the fixed rib position 121, avoiding the problem that the distance between the two is too large to effectively cooperate.

[0053] In other embodiments, the fixed rib position 121 can also be arranged on the outside of the installation opening 12, as long as the end of the fixed rib position 121 extends into the installation opening 12 so that the air inlet cover 2 can form extrusion against the fixed rib position 121 after it extends in, which is not limited here.

[0054] It should be noted that the present utility model does not limit the setting position of the fixed rib position 121, and it can be one of the following embodiments:

[0055] Embodiment 1: In this embodiment, the fixed rib positions 121 are arranged on opposite sides of the installation opening 12. After the air inlet cover 2 is installed, the fixed rib positions 121 on both sides clamp the air inlet cover 2 inward at the same time, firmly fixing the air inlet cover 2. Specifically, the fixed rib positions 121 can be located on the upper and lower sides of the installation opening 12, or on the left and right sides of the installation opening 12, which is not limited here.

[0056] Embodiment 2: In this embodiment, as Figure 5 , Figure 6 shown, the fixed rib position 121 is in multiple segments and is arranged along the circumferential direction of the installation opening 12, and there is a clearance groove 122 between adjacent two segments of the fixed rib position 121.

[0057] The fixed rib position 121 surrounds the installation opening 12 and can form clamping and fixing on multiple circumferential regions of the air inlet cover 2, thus not only further improving the fixing stability of the air inlet cover 2, but also being able to limit the air inlet cover 2 to prevent it from shifting under the extrusion effect. At the same time, the clearance groove 122 between the fixed rib positions 121 improves the elastic deformation ability of the fixed rib position 121, making it more easily elastically deform when being pushed by the air inlet cover 2, thereby reducing the frictional resistance between the two during the assembly process, making the installation of the air inlet cover 2 more labor-saving and improving the assembly experience.

[0058] Among them, the clearance groove 122 can completely separate two segments of the fixed rib position 121, or can reduce the strength of the region between two segments of the fixed rib position 121 by reducing the thickness of the region between two segments of the fixed rib position 121, reducing the height of the region between two segments of the fixed rib position 121, etc., so as to achieve the effect that the fixed rib position 121 is more easily deformed.

[0059] In a preferred embodiment of the present utility model, asFigure 4 As shown, an installation sunk platform 13 that is recessed inward is provided on the outer wall of the outer cover 11, and the installation opening 12 is located within the installation sunk platform 13, so that at least a part of the air inlet cover 2 is accommodated within the installation sunk platform 13.

[0060] The installation sunk platform 13 can accommodate at least a part of the air inlet cover 2, so that at least a part of the air inlet cover 2 is accommodated within the installation sunk platform 13. Furthermore, the outer surface of the air inlet cover 2 can be made as flush as possible with the outer surface of the outer cover 11, reducing the step difference between the two and preventing the air inlet cover 2 from protruding too much from the surface of the outer cover 11, thus ensuring the appearance quality and feel of the cooking appliance. At the same time, the installation sunk platform 13 can limit the air inlet cover 2, restricting the air inlet cover 2 within the installation sunk platform 13 and making the position of the air inlet cover 2 more stable.

[0061] In one embodiment, the guiding portion of the fixing rib 121 forms the installation sunk platform 13, and the clamping portion is located inside the installation sunk platform 121 for clamping the air inlet cover 2. Of course, the guiding portion of the fixing rib 121 can also extend towards the inside of the pot body 1 in other ways, as long as the clamping portion is within the projection of the installation opening 12.

[0062] Preferably, as Figure 4 shown, the air inlet cover 2 includes a cover body 23 and an installation rib 22 that extends towards the inside of the pot body 1. There is a stepped surface 24 between the cover body 23 and the installation rib 22. The stepped surface 24 can abut against the bottom wall of the installation sunk platform 13 so that the cover body 23 is located within the installation sunk platform 13. The installation rib 22 passes through the installation opening 12 to abut and cooperate with the fixing rib 121. As Figure 4 shown, the length L1 of the installation rib 22 is greater than the length L2 of the clamping portion in the radial direction of the pot body 1.

[0063] The abutting cooperation between the stepped surface 24 and the installation sunk platform 13 can serve as a positioning indication for the installation of the air inlet cover 2. When they abut, it indicates that the air inlet cover 2 has been installed in place. The length of the installation rib 22 being greater than the length of the clamping portion in the radial direction of the pot body 1 means that after the air inlet cover 2 is installed in place, the fixing rib 121 clamps the side wall of the installation rib 22, preventing the air inlet cover 2 from moving axially along the installation opening 12. The fixing rib 121 will not act on the inner end of the installation rib 22, avoiding the air inlet cover 2 moving axially outward along the installation opening 12 under the clamping force of the fixing rib 121 and causing the air inlet cover 2 to slip out of the installation opening 12.

[0064] In one embodiment, barbs can also be provided at the inner end of the installation rib 22 to engage with the fixing rib 121, thereby further restricting the air inlet cover 2 from slipping out.

[0065] As a preferred embodiment of the present utility model, the air inlet cover 2 is provided with a shielding rib protruding radially outward along the mounting opening 12, and the shielding rib is located outside the outer cover 11 to shield the gap between the air inlet cover 2 and the outer cover 11.

[0066] After the air inlet cover 2 is installed, the shielding rib is located outside the mounting opening 12, shielding the gap between the air inlet cover 2 and the outer cover 11, so that the user cannot see the gap between the air inlet cover 2 and the outer cover 11 from the perspective of directly facing the air inlet cover 2. On the one hand, the appearance quality of the cooking appliance is improved, and on the other hand, it can prevent external dust, oil stains, etc. from entering the gap between the two, ensuring the cleanliness of the installation position of the air inlet cover 2 and reducing the user's cleaning pressure.

[0067] It should be noted that the present utility model does not limit the installation position of the cooling fan. In one embodiment, as Figure 1 shown, the outer cover 11 includes a housing 111 surrounding the side of the pot body 1 and a base 112 located at the bottom of the pot body 1. The cooling fan is arranged on the side of the pot body 1, the mounting opening 12 is opened on the housing 111 and corresponds to the cooling fan, and the air inlet cover 2 is fixed to the mounting opening 12. In this embodiment, the cooking appliance takes in air from the side, and the cooling fan blows the air flow towards the inner wall of the inner pot.

[0068] In another embodiment, the outer cover 11 includes a housing 111 surrounding the side of the pot body 1 and a base 112 located at the bottom of the pot body 1. The cooling fan is arranged at the bottom of the pot body 1, the mounting opening 12 is opened on the base 112 and corresponds to the cooling fan, and the air inlet cover 2 is fixed to the mounting opening 12.

[0069] In this embodiment, the cooking appliance takes in air from the bottom, and the cooling fan blows the air flow towards the bottom of the inner pot. Compared with the air intake from the side, the air inlet cover 2 is located at the bottom of the cooking appliance, which can achieve a hidden design and improve the appearance quality of the cooking appliance. Specifically, the base 112 is further provided with a plurality of support feet to provide an air intake gap between the air inlet cover 2 and the tabletop.

[0070] In the present utility model, the parts not described can be realized by adopting or referring to the existing technologies.

[0071] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0072] The above are only the embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
