Description

Technical Field

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

[0002] The cooking utensil comprises an outer shell assembly, a pot body and a cover body covered on the pot body. The pot body comprises a heat preservation cover and an inner pot, wherein the heat preservation cover is fixedly arranged in the outer shell assembly, and the inner pot is removably arranged in the heat preservation cover. The heat preservation cover is provided with pot teeth, and the cover body is provided with cover teeth. The cover body comprises a cover body and a sealing ring arranged on the cover body. When the cover teeth are engaged with the pot teeth, the cover body is in a closed cover position, and the sealing ring is sealed with the inner pot. When the cover teeth are staggered with the pot teeth, the cover body is in an open cover position, and the cover body can be separated from the pot body.

[0003] In the related art, in order to improve the sealing between the lid and the pot body, when the lid is in the closed position, the weight of the lid is completely borne by the inner pot, and the sealing ring is pressed between the lid body and the inner pot, so that the friction between the sealing ring and the inner pot is relatively large.

[0004] In this way, when the lid needs to be switched from the closed position to the open position, due to the large friction between the lid and the pot body, the lid will drive the inner pot to move, so that the inner pot rotates when the lid rotates, or the inner pot is lifted when the lid is lifted, which easily causes the pot to be sucked. Utility Model Content

[0005] The main purpose of the utility model is to provide a cooking utensil to solve the problem in the related art that when the cover is opened, the friction between the cover and the pot body is large, which easily causes the pot to be sucked.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a cooking utensil, comprising: a shell assembly, comprising a shell and a middle plate arranged on the top of the shell, on which a load-bearing protrusion is arranged; a pot body, arranged in the shell assembly, on which a pot tooth is arranged; a cover body, on which a cover tooth and an abutting protrusion capable of abutting and cooperating with the load-bearing protrusion are arranged, and the cover body can be rotatably arranged on the pot body to have a closed cover position in which the pot tooth and the cover tooth are engaged, and a cover open position in which the pot tooth and the cover tooth are staggered; wherein there are multiple load-bearing protrusions and multiple abutting protrusions, and the multiple load-bearing protrusions correspond to the multiple abutting protrusions one by one, and when the cover body is switched from the closed cover position to the open cover position, the abutting protrusion abuts and cooperates with the load-bearing protrusion.

[0007] By applying the technical solution of the utility model, when the cover body switches from the closed position to the open position, the load-bearing protrusion can cooperate with the abutting protrusion so that the weight of the cover body can be transferred to the middle plate through the load-bearing protrusion and the abutting protrusion. In this way, when the cover is opened, the middle plate can bear part of the weight of the cover body to reduce the weight of the cover body borne by the pot body. In addition, due to the cooperation between the load-bearing protrusion and the abutting protrusion, the distance between the cover body and the pot body in the vertical direction can be increased when the cover is opened, and the cover body can partially leave the pot body, reducing the contact area between the cover body and the pot body. Due to the reduction in the weight of the cover body borne by the pot body and the reduction in the contact area between the cover body and the pot body, the friction between the cover body and the pot body is reduced, reducing the possibility of the cover body driving the pot body to move when the cover is opened, thereby reducing the occurrence of the pot suction phenomenon. Therefore, the technical solution of the present application effectively solves the problem in the related art that the friction between the cover body and the pot body is large when the cover is opened, which is easy to cause the pot suction phenomenon.

[0008] Furthermore, a plurality of load-bearing protrusions are arranged at equal intervals on the middle plate, and a plurality of abutting protrusions are arranged at equal intervals on the cover body. The above arrangement enables the cover body to evenly distribute the weight of the cover body on the middle plate when the cover is opened, so that the force on the middle plate is more even.

[0009] Furthermore, the load-bearing protrusion includes a lid-opening inclined surface extending along the circumference of the pot body. The above arrangement enables the abutting protrusion to rotate along the lid-opening inclined surface during the process of the lid body rotating from the lid-closing position to the lid-opening position, and the lid body can be slowly lifted up by the lid-opening inclined surface, so that the distance between the lid body and the pot body in the vertical direction can be increased when the lid is opened, the contact area between the lid body and the pot body is gradually reduced, and the cooperation between the load-bearing protrusion and the abutting protrusion in the process is smoother.

[0010] Furthermore, the load-bearing protrusion also includes a protrusion, the cover opening inclined surface is connected to one side of the protrusion, and in the cover opening direction of the cover body, the cover opening inclined surface and the protrusion are arranged in sequence. The above arrangement can prevent the abutting protrusion from automatically sliding onto the cover opening inclined surface, and prevent the cover body from accidentally rotating to the closed position.

[0011] Furthermore, the load-bearing protrusion also includes a lid closing inclined surface, and the lid closing inclined surface, the protrusion and the lid opening inclined surface are arranged in sequence along the closing direction of the lid body, and the lid closing inclined surface extends along the circumferential direction of the pot body. The above-mentioned lid closing inclined surface can play a role of guiding and smooth transition in the process of opening and closing the lid, and also has the functions of being beautiful and easy to clean.

[0012] Furthermore, the slope of the lid closing slope is greater than the slope of the lid opening slope; and / or the inclination angle of the lid opening slope is within the range of 1° to 5°. The above arrangement facilitates the lid to be slowly lifted up. It also enables the pot teeth and the lid teeth to be staggered first, avoiding interference between the pot teeth and the lid teeth, so as to ensure that the lid can be fully opened.

[0013] Furthermore, the abutting protrusion has a first height in the vertical direction, the bearing protrusion has a second height in the vertical direction, and the sum of the first height and the second height is in the range of 1 mm to 3 mm. The above arrangement reduces the contact area and pressure between the lid and the pot body, thereby reducing the occurrence of pot suction phenomenon.

[0014] Furthermore, the load-bearing protrusion further includes a first transition arc surface connected between the protrusion and the lid closing inclined surface; and / or, the load-bearing protrusion further includes a second transition arc surface connected between the protrusion and the lid opening inclined surface. The above arrangement enables the abutting protrusion to abut and cooperate with the load-bearing protrusion more smoothly when the cover body drives the abutting protrusion to move together.

[0015] Furthermore, the cover teeth are arranged at intervals along the circumference of the cover body, the pot teeth are arranged at intervals along the circumference of the pot body, the cover teeth correspond to the pot teeth one by one, and the bearing protrusion is arranged at the interval between two adjacent pot teeth. The above arrangement facilitates the assembly of the housing assembly and the pot body, and also enables the bearing protrusion to be staggered with the pot teeth.

[0016] Furthermore, there are a plurality of cover teeth arranged at intervals along the circumference of the cover body, and a plurality of pot teeth arranged at intervals along the circumference of the pot body, and the plurality of cover teeth correspond to the plurality of pot teeth one by one, and the length of each cover tooth along the circumference of the cover body is greater than the length of the corresponding pot tooth along the circumference of the pot body; a cover tooth gap is formed between each two adjacent cover teeth, and a pot tooth gap is formed between each two adjacent pot teeth, and the plurality of cover tooth gaps correspond to the plurality of pot tooth gaps one by one, and the length of each cover tooth gap along the circumference of the cover body is less than the length of the corresponding pot tooth gap along the circumference of the pot body. Such an arrangement enables the cover teeth to enter the longer pot tooth gap when the cover body is buckled on the pot body, thereby reducing the possibility of collision between the cover teeth and the pot teeth and extending the service life.

[0017] Furthermore, the abutting protrusion is located outside the cover teeth, and the bearing protrusion is located on the upstream side of the pot teeth in the cover closing direction and is arranged adjacent to the pot teeth. In this way, when opening the cover, the bearing protrusion can cooperate with the abutting protrusion more timely.

[0018] Further, the abutting protrusion is a convex rib arranged on the cover body, and the convex rib extends along the circumference of the cover body; and / or, the cover body includes a surface cover and an inner cover arranged inside the surface cover, the cover teeth are arranged on the inner cover, and the abutting protrusion is arranged on the side of the surface cover facing the pot body.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0034] like Figures 1 to 4As shown, the cooking utensil of this embodiment includes: a housing assembly 10, a pot body 20 and a cover body 30. The housing assembly 10 includes a housing 11 and a middle plate 12 arranged on the top of the housing 11, and a load-bearing protrusion 13 is arranged on the middle plate 12. The pot body 20 is arranged in the housing assembly 10, and a pot tooth 211 is arranged on the pot body 20. The cover body 30 is provided with a cover tooth 321 and an abutting protrusion 311 that can abut against the load-bearing protrusion 13. The cover body 30 is rotatably arranged on the pot body 20 to have a closed cover position in which the pot tooth 211 is buckled with the cover tooth 321 and an open cover position in which the pot tooth 211 is staggered with the cover tooth 321. Among them, the load-bearing protrusion 13 and the abutting protrusion 311 are both multiple, and the multiple load-bearing protrusions 13 correspond to the multiple abutting protrusions 311 one by one. When the cover body 30 is switched from the closed cover position to the open cover position, the abutting protrusion 311 abuts against the load-bearing protrusion 13.

[0035] By applying the technical solution of this embodiment, when the cover 30 is switched from the cover-closed position to the cover-opened position, the load-bearing protrusion 13 can cooperate with the abutting protrusion 311, so that the weight of the cover 30 can be transferred to the middle plate 12 through the load-bearing protrusion 13 and the abutting protrusion 311. In this way, when the cover is opened, the middle plate 12 can bear part of the weight of the cover 30 to reduce the weight of the cover 30 borne by the pot body 20, so that the friction between the cover 30 and the pot body 20 is reduced, and the possibility of the cover 30 driving the pot body 20 to move when the cover is opened is reduced, thereby reducing the occurrence of the pot suction phenomenon. Therefore, the technical solution of the present application effectively solves the problem in the related art that the friction between the cover and the pot body is large when the cover is opened, and the pot suction phenomenon is easy to occur. In addition, through the arrangement of multiple load-bearing protrusions 13 and multiple abutting protrusions 311, the weight distribution of the cover 30 on the middle plate 12 when the cover is opened is more uniform, so that the middle plate 12 can better bear the weight of the cover 30, and the operation of opening the cover is smoother.

[0036] In this embodiment, the pot body 20 includes a heat preservation cover 21 and an inner pot 22, the heat preservation cover 21 is fixedly arranged in the outer shell assembly 10, and the inner pot 22 is removably arranged in the heat preservation cover 21. The cover body 30 includes a cover body and a sealing ring 33 arranged on the cover body. When the cover body 30 is in the closed position, the sealing ring 33 is sealed with the inner pot 22. The arrangement of the load-bearing protrusion 13 and the abutting protrusion 311 can not only transfer the weight of the cover body 30 to the middle plate 12. When the lid is opened, the cooperation of the bearing protrusion 13 and the abutting protrusion 311 can also push the lid 30 upward relative to the middle plate 12, so that the sealing ring 33 on the lid body can move upward, and the inner pot 22 has space to move downward relative to the lid 30. Under the action of its own gravity, the pot 20 can overcome the friction between the pot 20 and the sealing ring 33 of the lid 30, so that the friction between the sealing ring of the lid 30 and the inner pot 22 of the pot 20 is reduced, and the contact area between the sealing ring of the lid 30 and the inner pot 22 of the pot 20 is reduced, thereby further reducing the occurrence of pot suction. When the bearing protrusion 13 and the abutting protrusion 311 are in abutment, the lid 30 is pushed up by 1mm to 3mm relative to the middle plate 12.

[0037] like Figures 1 to 4 As shown, a plurality of load-bearing protrusions 13 are arranged at equal intervals on the middle plate 12, and a plurality of abutting protrusions 311 are arranged at equal intervals on the cover body 30. In this way, when the cover is opened, the weight of the cover body 30 can be evenly distributed on the middle plate 12 through the load-bearing protrusions 13 and abutting protrusions 311 arranged at equal intervals, so that the force on the middle plate 12 is more uniform, and the cover can be opened more smoothly.

[0038] It should be noted that "plurality" refers to two, three or more than three. In this embodiment, there are three load-bearing protrusions 13 arranged at equal angles with the axis of the pot body 20 as the center, and there are three abutting protrusions 311 arranged at equal angles with the axis of the pot body 20 as the center. When the lid body 30 is in the open position, the three load-bearing protrusions 13 abut against the three abutting protrusions 311 in a one-to-one corresponding manner.

[0039] like Figures 1 to 5 As shown, the bearing projection 13 includes a cover opening inclined surface 133 extending along the circumference of the pot body 20. In this way, when the cover body 30 rotates from the cover closing position to the cover opening position, the abutting projection 311 rotates along the cover opening inclined surface 133, and the cover body 30 can be slowly lifted up by the cover opening inclined surface 133, so that when the cover is opened, the distance between the cover body 30 and the pot body 20 in the vertical direction can be increased, the contact area between the cover body 30 and the pot body 20 is gradually reduced, and the matching of the bearing projection 13 and the abutting projection 311 in the process is smoother.

[0040] like Figures 1 to 5As shown, the load-bearing protrusion 13 includes a protrusion 131, and a cover-opening inclined surface 133 is connected to one side of the protrusion 131, and in the cover-opening direction N1 of the cover body 30, the cover-opening inclined surface 133 and the protrusion 131 are sequentially arranged. In this way, during the cover-opening process, when the abutting protrusion 311 abuts against the protrusion 131, the cover body stays there, playing a supporting role, preventing the abutting protrusion 311 from automatically sliding onto the cover-opening inclined surface 133, and preventing the cover body from mistakenly rotating to the closed position. Specifically, the protrusion has a load-bearing plane that supports the cover body.

[0041] like Figures 1 to 5 As shown, the load-bearing protrusion 13 further includes a lid closing inclined surface 132. The lid closing inclined surface 132, the protrusion 131 and the lid opening inclined surface 133 are arranged in sequence along the lid opening and closing direction N2 of the lid body 30. The lid closing inclined surface 132 extends along the circumferential direction of the pot body 20. The lid closing inclined surface 132 can play a role of guiding and smooth transition in the process of opening and closing the lid, and also has the functions of being beautiful and easy to clean.

[0042] like Figures 1 to 5 As shown, the slope of the lid closing slope 132 is greater than the slope of the lid opening slope 133, so that the lid body 30 can be slowly lifted up, so that the pot body 20 can be better separated from the lid body 30. The inclination angle of the lid opening slope 133 is within the range of 1° to 5°. In this way, the pot teeth 211 and the cover teeth 321 can be staggered first, avoiding interference between the pot teeth 211 and the cover teeth 321, so as to ensure that the lid can be fully opened.

[0043] It should be noted that the inclination angle of the cover opening slope 133 refers to the angle of the inclination between the axis of the cover opening slope 133 along the inclination direction and the middle plate 12. The inclination angle of the cover opening slope 133 is 1°, 2°, 3°, 4° or 5°.

[0044] like Figures 1 to 5 As shown, the abutting protrusion has a first height in the vertical direction, the bearing protrusion has a second height in the vertical direction, and the sum of the first height and the second height is in the range of 1 mm to 3 mm. The above arrangement reduces the contact area and pressure between the lid and the pot body, thereby reducing the occurrence of pot suction.

[0045] like Figures 1 to 5 As shown, the load-bearing protrusion 13 also includes a first transition arc surface 134 connected between the protrusion 131 and the cover closing inclined surface 132. The load-bearing protrusion 13 also includes a second transition arc surface 135 connected between the protrusion 131 and the cover opening inclined surface 133. The arrangement of the first transition arc surface 134 and the second transition arc surface 135 enables the abutting protrusion 311 to abut against the load-bearing protrusion 13 more smoothly when the cover body 30 drives the abutting protrusion 311 to move together, so that the movement of the cover body 30 is smoother, and the cover opening and closing operations are smoother.

[0046] In other embodiments, the load-bearing protrusion 13 further includes a first transition arc surface 134 connected between the protrusion 131 and the cover closing slope 132. Alternatively, the load-bearing protrusion 13 further includes a second transition arc surface 135 connected between the protrusion 131 and the cover opening slope 133.

[0047] like Figures 1 to 4 As shown, the cover teeth 321 are arranged at intervals along the circumference of the cover body 30, and the pot teeth 211 are arranged at intervals along the circumference of the pot body 20. The multiple cover teeth 321 correspond to the multiple pot teeth 211. The load-bearing protrusion 13 is arranged corresponding to the interval between two adjacent pot teeth 211. Such an arrangement facilitates the processing of the load-bearing protrusion 13. In addition, the load-bearing protrusion 13 is arranged at the interval between the two pot teeth 211, which facilitates the assembly of the housing assembly 10 and the pot body 20, and also enables the load-bearing protrusion 13 to be staggered with the pot teeth 211.

[0048] In this embodiment, since the bearing protrusion 13 is arranged correspondingly to the interval between two adjacent pot teeth 211, when the cover body 30 rotates from the cover-closed position to the cover-opened position, that is, during the rising process of the cover body 30, in order to avoid the interference between the cover teeth 321 and the pot teeth 211, the cover teeth 321 can move from the position where they cooperate with the pot teeth 211 to the interval between the two pot teeth 211, and at this time, the cover teeth 321 and the pot teeth 211 are staggered. That is, when the cover body 30 switches to the cover-opened position, the bearing protrusion 13 can abut against the abutting protrusion 311, so that the sealing ring 33 moves upward, and the contact area between the sealing ring 33 and the inner pot 22 is reduced. In this way, when the bearing protrusion 13 abuts against the abutting protrusion 311, the possibility of interference between the cover teeth 321 and the pot teeth 211 can be effectively avoided.

[0049] In this embodiment, the projection of the load-bearing protrusion 13 on the middle plate 12 is located outside the projection of the pot teeth 211 on the middle plate 12 .

[0050] like Figures 1 to 4As shown, there are a plurality of cover teeth 321 arranged at intervals along the circumference of the cover body 30, and a plurality of pot teeth 211 arranged at intervals along the circumference of the pot body 20, and the plurality of cover teeth 321 correspond to the plurality of pot teeth 211 one by one. The length of each cover tooth 321 along the circumference of the cover body 30 is greater than the length of the corresponding pot tooth 211 along the circumference of the pot body 20. A cover tooth gap 322 is formed between each two adjacent cover teeth 321, and a pot tooth gap 212 is formed between each two adjacent pot teeth 211. The plurality of cover tooth gaps 322 correspond to the plurality of pot tooth gaps 212 one by one, and the length of each cover tooth gap 322 along the circumference of the cover body 30 is less than the length of the corresponding pot tooth gap 212 along the circumference of the pot body 20. Such an arrangement enables the cover teeth 321 to enter the gap of the pot tooth 211 with a longer length when the cover body 30 is buckled on the pot body 20, thereby reducing the possibility of collision between the cover teeth 321 and the pot teeth 211, and extending the service life. Furthermore, since the length of the cover teeth 321 is greater than the length of the pot teeth 211 , the locking fit between the cover teeth 321 and the pot teeth 211 is tighter and more reliable.

[0051] In this embodiment, “corresponding thereto” means that when the cover body 30 is in the closed position, the cover teeth 321 and the corresponding pot teeth 211 are engaged with each other, and the cover tooth gaps 322 and the corresponding pot tooth gaps 211 are connected.

[0052] like Figures 1 to 4 As shown, the abutting protrusion 311 is located on the outside of the cover teeth 321, and the bearing protrusion 13 is located on the upstream side of the pot teeth 211 in the cover closing direction N2 and is arranged adjacent to the pot teeth 211. In this way, when opening the cover, the bearing protrusion 13 can cooperate with the abutting protrusion 311 more timely, further reducing the occurrence of the pot suction phenomenon.

[0053] In this embodiment, the first pot teeth and the second pot teeth are arranged at intervals on the pot body 20. When the lid is closed, the cover teeth 321 are away from the second pot teeth to rotate below the first pot teeth. When the lid is opened, the cover teeth 321 leave the first pot teeth and rotate toward the second pot teeth.

[0054] It should be noted that “adjacent arrangement” means that there is a certain distance between the load-bearing protrusion 13 and the first pot teeth 211, and the distance between the first pot teeth 211 is smaller than the distance between the load-bearing protrusion 13 and the second pot teeth 211. “Outer side of the cover teeth 321” means that the direction of the cover teeth 321 toward the axis of the cover body 30 is the inner side, and the direction of the cover teeth 321 away from the axis of the cover body 30 is the outer side.

[0055] Specifically, with the axis of the cooking utensil as the center, the angle between the cover teeth 321 and the pot teeth 211 in the cover closing direction N2 is more than 10 degrees. This ensures that the cover teeth 321 can begin to overlap with the pot teeth 211 only after the cover body 30 rotates more than 10 degrees. The abutting protrusion 311 is a convex rib provided on the cover body 30, and the convex rib extends along the circumference of the cover body 30. Accordingly, the length of the convex rib extending along the circumference of the cover body 30 is less than 10 degrees, so as to avoid the cover body 30 switching between the open cover position and the closed cover position not being smooth.

[0056] like Figure 6 As shown, the abutting protrusion 311 is a convex rib provided on the cover body 30, and the convex rib extends along the circumference of the cover body 30. The convex rib has a simple structure and is easy to process. The cover body 30 includes a surface cover 31 and an inner cover 32 provided inside the surface cover 31, the cover teeth 321 are provided on the inner cover 32, and the abutting protrusion 311 is provided on the side of the surface cover 31 facing the pot body 20. Providing the abutting protrusion 311 on the surface cover 31 facilitates the processing of the abutting protrusion 311.

[0057] In this embodiment, the abutting protrusion 311 is located on the outer side of the covering tooth 321 .

[0058] In other embodiments, the abutting protrusion 311 is a convex rib provided on the cover body 30, and the convex rib extends along the circumference of the cover body 30. Alternatively, the cover body 30 includes a surface cover 31 and an inner cover 32 provided inside the surface cover 31, the cover teeth 321 are provided on the inner cover 32, and the abutting protrusion 311 is provided on a side of the surface cover 31 facing the pot body 20.

The cover body 30 is detachably arranged on the pot body 20, and the cover body 30 includes a cover body and a sealing ring 33 arranged on the cover body. When the cover body 30 is in the closed position, the sealing ring 33 is sealed with the inner pot 22. The arrangement of the sealing ring 33 makes the sealing performance of the cover body 30 and the pot body 20 better.

[0060] like Figures 1 to 4 As shown, the sum of the height of the abutting protrusion 311 in the vertical direction and the height of the load-bearing protrusion 13 in the vertical direction is in the range of 1mm to 3mm. In this way, when the load-bearing protrusion 13 and the abutting protrusion 311 are in abutment with each other, the cover body 30 is lifted upward by 1mm to 3mm relative to the middle plate 12, so that the contact area and pressure between the cover body 30 and the pot body 20 are reduced, thereby reducing the occurrence of the pot suction phenomenon.

[0061] It should be noted that the sum of the height of the abutting protrusion 311 in the vertical direction and the height of the load-bearing protrusion 13 in the vertical direction is 1 mm, 2 mm or 3 mm.

[0062] In this embodiment, the cover body comprises a surface cover 31 and an inner cover 32. The cooking appliance is an electric pressure cooker.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0064] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0065] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0066] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model.
