Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a support ring, a housing, a manufacturing process for the housing, and household appliances. Background Technology

[0002] An induction cooker or electric hot pot uses a support ring fixed to the base. The support ring has a hollow structure and stepped mounting cavities. The lower first mounting cavity houses the bottom heating device, and its surface has a glass panel for user operation. The upper second mounting cavity houses the side heating device and is used to hold the pot. When the pot is placed in the second mounting cavity, it can cook rice. This type of cooker is also known as a split-type rice cooker, which expands the functionality of induction cookers or electric hot pots and is becoming increasingly popular.

[0003] Since the first and second mounting cavities on the support ring are both quite deep, and the support ring as a whole has a ring-shaped stepped structure, in actual production, a glass panel needs to be installed on the surface of the first mounting cavity. Usually, the glass panel is fixed to the surface of the first mounting cavity by applying glue. After the glass panel is glued to the surface of the first mounting cavity, a heavy object needs to be used to press down on the glass panel and leave it for at least 24 hours to ensure the reliability of the glue adhesion.

[0004] The surface area for mounting the glass panel on the first mounting cavity is not large, and there is also a second mounting cavity above it. It is not easy to place the ballast weights on the glass panel. When the weights do not match the size of the mounting surface, it is even necessary to manufacture matching ballast weights separately, which is costly. At the same time, since the first and second mounting cavities of the support ring are both deep, it is inconvenient to store and transfer a large number of support rings when mass-producing them. Summary of the Invention

[0005] In view of this, the present invention provides a support ring, a housing, a manufacturing process for the housing, and a household appliance to solve the problems of difficulty in placing heavy loads on the support ring when the glass panel is glued on during production, and the inconvenience of storing and transferring the support ring during mass production.

[0006] In a first aspect, the present invention provides a support ring, comprising:

[0007] First mounting cavity;

[0008] A second mounting cavity is located below the first mounting cavity. A mounting surface is connected between the top of the second mounting cavity and the outer bottom of the first mounting cavity. The mounting surface is suitable for adhesive bonding of panels.

[0009] A support structure is disposed within the second mounting cavity, wherein at least the projection of the bottom of the support structure is on the mounting surface, and the height of the support structure is greater than the height of the first mounting cavity.

[0010] Beneficial effects: By setting a support structure in the second mounting cavity, and the height of the support structure being greater than the height of the first mounting cavity, multiple support rings can be stacked together during mass production, making it convenient to store and transfer them during production. Simultaneously, since at least the bottom projection of the support structure is on the mounting surface, when multiple support rings are stacked, the support structure of the upper support ring can press down on the panel of the lower support ring. This allows the support ring's own weight to hold the panel in place when it is glued to the mounting surface, ensuring reliable adhesion without the need for separate ballast weights, saving costs. Furthermore, since the support rings are generally the same size during production, there is no need to worry about mismatched ballast weights. This also ensures that the stacked support rings are placed stably and are not easily tipped over, facilitating packaging, batch transport, and storage during production.

[0011] In one alternative implementation, the height of the support structure is greater than the height of the second mounting cavity in the vertical direction.

[0012] Beneficial effects: By setting the height of the support structure to be greater than the height of the first mounting cavity and the second mounting cavity, the stacking of multiple support rings is more stable and will not interfere with each other. This solves the problem of possible interference between adjacent support rings when multiple support rings are stacked, which affects the stacking.

[0013] In one alternative implementation, the support structure is a screw post or a support post.

[0014] Beneficial effects: By setting the support structure as a screw post, the support ring can be directly fixed and assembled with other structures through the support structure, saving on the number of parts required.

[0015] In one alternative implementation, the entire projection of the support structure lies on the mounting surface.

[0016] Beneficial effects: By placing the entire projection of the support structure on the mounting surface, when multiple support rings are stacked, the entire weight of the support structure can be pressed on the top of the panel, ensuring the ballast force. At the same time, it makes the stacked support rings more stable and less prone to tipping over.

[0017] In one alternative embodiment, the sidewalls of the first mounting cavity are inclined.

[0018] Beneficial effects: By setting the sidewall of the first mounting cavity as an inclined structure, it can play a certain guiding and positioning role for the panel during the assembly process of the panel to the mounting surface, thereby improving assembly efficiency. Moreover, when multiple support rings are stacked, the inclined sidewall of the first mounting cavity can facilitate nesting into the second mounting cavity of the adjacent support ring.

[0019] In one alternative embodiment, the support structure is provided in multiple circumferential directions;

[0020] And / or, the support structure includes at least a two-stage stepped structure.

[0021] Beneficial effects: Since the support ring is a ring structure, by setting multiple support structures along the circumference, when multiple support rings are stacked, the panel has multiple support structures in the circumference. The overall downward ballast force of the upper support ring can be distributed through multiple support structures, preventing the ballast force from being too concentrated and causing damage to the panel. Since the height of the support structure needs to be set relatively high, higher than the height of the second mounting cavity and the first mounting cavity, in order to ensure the strength of the support structure, the support structure is set as a stepped structure with at least two sections, which can increase the height and strengthen the support structure.

[0022] Secondly, the present invention also provides a housing, comprising:

[0023] The aforementioned support ring;

[0024] The panel is glued to the mounting surface.

[0025] The base is fixedly connected to the lower part of the support ring.

[0026] Beneficial effects: Since the housing includes the aforementioned support ring, it has the same effect as the aforementioned support ring, which will not be repeated here.

[0027] In one alternative embodiment, the bottom of the support structure protrudes from the second mounting cavity, and the base has a clearance space corresponding to the support structure.

[0028] Beneficial effects: Due to the protrusion of the second mounting cavity at the bottom of the support structure, the support structure is relatively high. By setting a clearance space on the base at the corresponding position, the assembly of the base and the support ring can be facilitated, and the overall space of the shell can be prevented from being set too high.

[0029] Thirdly, the present invention also provides a manufacturing process for a housing, applicable to the aforementioned housing, comprising:

[0030] Adhesive is placed on the mounting surface of one of the support rings;

[0031] The panel is placed above the mounting surface to complete the assembly of multiple housings;

[0032] One of the completed housings is stacked on top of the other completed housing, such that the support structure of the upper housing presses onto the panel of the lower housing.

[0033] Fourthly, the present invention also provides a household appliance, comprising:

[0034] The aforementioned casing.

[0035] Beneficial effects: Since household appliances include the aforementioned support rings and have the same effects as the aforementioned support rings, they will not be described in detail here.

[0036] In one alternative implementation, the household appliance is a separate rice cooker. Attached Figure Description

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] During the production of the split-type rice cooker, the applicant discovered that the mounting cavities for the pot body and heating element on the support ring are quite deep and have a stepped structure. The glass panel of the rice cooker is glued to the surface of the first mounting cavity below the support ring. To ensure reliable adhesion, the glass panel requires additional weights to be placed on it for at least 24 hours. However, the surface area for the glass panel on the first mounting cavity is not large, and there is also a second mounting cavity above it. Placing weights on the glass panel is difficult, and when the weights do not match the dimensions of the mounting surface, it is even necessary to manufacture matching weights separately, increasing costs. Furthermore, because both the first and second mounting cavities of the support ring are deep, mass production of support rings makes storage and relocation inconvenient.

[0051] To address this problem, the applicant proposed a support ring and a household appliance incorporating it.

[0052] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0053] According to an embodiment of the present invention, in a first aspect, a support ring is provided, comprising: a first mounting cavity 1; a second mounting cavity 2 disposed below the first mounting cavity 1, wherein a mounting surface 3 is connected between the top of the second mounting cavity 2 and the outer side of the bottom of the first mounting cavity 1, and the mounting surface 3 is adapted to adhesively attach a panel 4; and a support structure disposed within the second mounting cavity 2, wherein at least the projection of the bottom of the support structure is on the mounting surface 3, and the height of the support structure is greater than the height of the first mounting cavity 1.

[0054] By setting a support structure in the second mounting cavity 2, and the height of the support structure is greater than the height of the first mounting cavity 1, it is convenient to stack multiple support rings together when mass-producing a large number of support rings. This makes it easy to store and transfer multiple support rings during production. Since the dimensions of the support rings are basically the same during production, there is no need to worry about the mismatch of the weight of the ballast panel. At the same time, it ensures that the stacked support rings can be placed stably and are not easy to tip over, which facilitates packaging, batch transfer and storage during production.

[0055] Meanwhile, since the projection of the support structure at least at the bottom is on the mounting surface 3, when multiple support rings are stacked, the support structure of the upper support ring can press down on the panel 4 of the lower support ring. In this way, when the panel 4 is glued to the mounting surface 3, the weight of the support ring itself can be used to press down the panel 4, ensuring the reliability of the glue, without the need to set up a separate ballast weight to hold the panel 4, thus saving costs.

[0056] The height direction defined here refers to the actual height direction of the support ring during use, which is also the up-down direction in the attached diagram. The horizontal direction defined here refers to the actual horizontal direction of the support ring during use, which is also the left-right direction in the attached diagram. The "above" and "below" defined here also refer to the actual above and below of the support ring during use.

[0057] like Figure 1 As shown, the support structure in this embodiment is a screw post 5. By setting the support structure as a screw post 5, it is convenient for the support ring to be directly fixed and assembled with other structures through the support structure, saving on the number of components.

[0058] As an alternative implementation, the support structure may not be a screw post, but rather a support post 11 specifically designed to support the stacked support rings, such as... Figure 9 As shown, specifically, four support columns 11 can be arranged at circumferential intervals in the second mounting cavity 2. At this time, the screw column 5 can be set at a lower position, with the bottom of the screw column 5 located inside the second mounting cavity 2, while the support column 11 is set at a higher position, with the bottom of the support column 11 protruding from the second mounting cavity 2.

[0059] The projection of the support structure is on the mounting surface 3, meaning that the screw post 5 is installed inside the second mounting cavity 2, located below the mounting surface 3. This ensures that when multiple support rings are stacked, the screw post 5 can fall outside the ring on the side wall 101 of the first mounting cavity, allowing the bottom of the screw post 5 to rest stably on the upper surface of the panel 4, thus guaranteeing a pressure load on the panel 4.

[0060] Specifically, in this embodiment, the entire projection of the screw post 5 lies on the mounting surface 3, i.e., as shown in the figure. Figure 5As shown, the projections 501 of the screw posts are all on the panel 4 on the mounting surface 3. By placing all the projections of the screw posts 5 on the mounting surface 3, when multiple support rings are stacked, the entire weight of the screw posts 5 can be pressed on the panel 4, ensuring the ballast force. At the same time, it makes the stacked support rings more stable and less prone to tipping over.

[0061] As an alternative implementation, the projection of the bottom of the screw post 5 may be on the mounting surface 3, while the projections of the rest of the structure may be outside the mounting surface 3.

[0062] Specifically, in the height direction, the height of the screw post 5 is greater than the height of the first mounting cavity 1 and the second mounting cavity 2, respectively. By setting the height of the screw post 5 to be greater than the height of the first mounting cavity 1 and the second mounting cavity 2, the stacking of multiple support rings is more stable, and there is no interference between the mounting cavities and support structures of adjacent support rings when multiple support rings are stacked. This solves the problem of potential interference between adjacent support rings when multiple support rings are stacked, which affects the stacking.

[0063] Here, the height of the screw post 5 refers to the height from the bottom surface of the mounting surface 3 of the support ring to the bottom surface of the screw post 5. Figure 3 As shown, the bottom of the screw post 5 protrudes from the second mounting cavity 2, meaning that the height of the screw post 5 is greater than the height of the second mounting cavity 2, which means that H1 is greater than 0.

[0064] like Figure 7 As shown, the height of the second mounting cavity 2 refers to the height H2 from the bottom surface of the mounting surface 3 of the support ring to the bottom surface of the side wall of the second mounting cavity 2; the height of the first mounting cavity 1 refers to the height H3 between the top surface of the mounting boss 6 and the top surface of the panel 4.

[0065] like Figure 1 As shown, the overall structure of the support ring is a ring-shaped stepped structure, with the first mounting cavity 1 located at the top and the second mounting cavity 2 located at the bottom.

[0066] The middle part of the first mounting cavity 1 is suitable for placing the pot body of the household appliance, and the side part is suitable for placing a side heating device to heat the side of the pot body when the household appliance is working; the second mounting cavity 2 is suitable for placing a bottom heating device of the household appliance to heat the bottom of the pot body when the household appliance is working.

[0067] like Figure 1 As shown, in this embodiment, the top of the first mounting cavity 1 is provided with a mounting boss 6. The annular cavity of the mounting boss 6 is suitable for placing the pot body. The bottom of the first mounting cavity 1 is connected to the top of the second mounting cavity 2 through the mounting surface 3. The panel 4 is glued to the mounting surface 3.

[0068] Panel 4 is the control panel for household appliances, and can be made of glass. Of course, panel 4 can also be made of other materials depending on actual needs; there are no major restrictions here.

[0069] To facilitate the application of adhesive, a glue-applying groove is provided on the mounting surface 3. By providing a glue-applying groove on the mounting surface 3, it is easy to add glue to the mounting surface 3 to achieve adhesive bonding between the panel 4 and the mounting surface 3.

[0070] In this embodiment, both the second mounting cavity 2 and the first mounting cavity 1 are annular cavity structures, therefore the mounting surface 3 is also annular, and the glue-applying groove is a recessed structure, that is, an annular recess. Alternatively, the glue-applying groove can be a plurality of separately arranged glue-applying grooves spaced apart along the circumference of the mounting surface 3, each glue-applying groove being a short recessed section. Alternatively, the mounting surface 3 can be a semi-annular structure, or only a partially arc-shaped structure; no further restrictions are imposed here.

[0071] In this embodiment, the glue applicator groove is provided with at least one partition structure 7. One side of the partition structure 7 forms an overflow space 9, and the other side forms a glue applicator space 8. By providing the partition structure 7 in the glue applicator groove, with one side forming an overflow space 9 and the other side forming a glue applicator space 8, when glue is added to the glue applicator space 8 of the mounting surface 3, if there is too much glue, the glue can flow into the overflow space 9, preventing excess glue from lifting the panel 4 and affecting the aesthetics of the panel 4 assembled on the mounting surface 3.

[0072] Specifically, such as Figure 2 As shown, the partition structure 7 is a raised rib, and there are two of them, dividing the glue applicator groove into three spaces: the two outer spaces are glue overflow spaces 9, and the middle space is the glue applicator space 8. For the overall structure, the partition structure 7 is a ring-shaped rib. Alternatively, in a different implementation, only one partition structure 7 can be provided, with one side of the partition structure 7 being the glue applicator space 8 and the other side being the glue overflow space 9. In this case, the glue overflow space 9 can be made smaller.

[0073] In the horizontal direction, the size of the glue overflow space 9 is smaller than the size of the glue application space 8. For example... Figure 2 As shown, the cross-sections of the glue overflow space 9 and the glue application space 8 are square, and the length of the glue overflow space 9 is less than the length of the glue application space 8.

[0074] Since the glue is mainly applied into the glue application space 8 during assembly, there will not be excessive glue. Setting the size of the overflow space 9 to be smaller than the size of the glue application space 8 ensures the correct amount of glue applied. Alternatively, the size of the overflow space 9 can be the same as the size of the glue application space 8. Another alternative implementation is that the size of the overflow space 9 is smaller than the size of the glue application space in both the horizontal and vertical directions.

[0075] like Figure 2 As shown, the top of the partition structure 7 is lower than the mounting surface 3. By setting the top of the partition structure 7 to be lower than the mounting surface 3, excess glue can overflow from the glue application space 8 through the top of the partition structure 7 into the overflow space 9 during glue application. Furthermore, when the panel 4 is assembled onto the mounting surface 3, there is still a certain distance between the bottom of the panel 4 and the top of the partition structure 7. When the panel 4 is assembled onto the mounting surface 3, excess glue can be evenly distributed to the bottom of the panel 4, further preventing excess glue from lifting the panel 4.

[0076] The top of the partition structure 7 can be 0.1mm-0.3mm below the mounting surface. Specifically, the top of the partition structure 7 is 0.2mm below the mounting surface. As an alternative implementation, the top of the partition structure 7 may also be 0.1mm, 0.3mm, 0.4mm, or other specific values ​​below the mounting surface 3.

[0077] In this embodiment, the sidewall 101 of the first mounting cavity is inclined. For example... Figure 3 As shown, the sidewall 101 of the first mounting cavity slopes outward from top to bottom. By setting the sidewall 101 of the first mounting cavity as an inclined structure, it can provide a certain guiding and positioning function for the panel 4 during the assembly process of the panel 4 onto the mounting surface 3, thereby improving assembly efficiency. At the same time, since the sidewall 101 of the first mounting cavity is inclined, when multiple support rings are stacked, it is easier to nest the first mounting cavity 1 of the lower support ring into the second mounting cavity 2 of the upper support ring, thus reducing the volume occupied when multiple support rings are stacked. As an alternative implementation, the sidewall 101 of the first mounting cavity can also be set vertically.

[0078] like Figure 1 As shown, in this embodiment, multiple screw posts 5 are provided circumferentially, such as four. In actual installation, the multiple screw posts 5 are evenly distributed circumferentially, which allows the load-bearing force to be released more evenly on the panel 4. Alternatively, the multiple screw posts 5 can be arranged at non-uniform intervals.

[0079] By arranging multiple screw posts 5 circumferentially, when multiple support rings are stacked, the panel 4 has multiple screw posts 5 circumferentially. The downward ballast force of the upper support ring can be distributed through multiple screw posts 5, preventing the ballast force from being too concentrated and causing damage to the panel 4. As an alternative implementation, six or more screw posts 5 can be arranged circumferentially along the bottom of the mounting surface 3.

[0080] Because the height of the screw post 5 needs to be relatively high, exceeding the heights of both the second mounting cavity 2 and the first mounting cavity 1, to ensure the strength of the screw post 5, it can be configured as a two-stage stepped structure, such as... Figure 8 As shown.

[0081] The upper section 502 of the screw post 5 is larger in size, while the lower section 503 is smaller in size, which can increase the height and strength of the screw post 5. As an alternative implementation, the screw post 5 can also be a single-section column, or to meet greater support strength, the screw post 5 can be set as a three-section or more-section stepped structure.

[0082] In some embodiments, when the screw post 5 is a tall two-stage stepped structure, and the size of the upper structure 502 is larger than the size of the lower structure 503, the projection of the bottom of the lower structure 503 of the screw post 5 may be on the mounting surface 3, while the projection of the upper structure 502 of the screw post 5 may be outside the mounting surface 3. Of course, it is also possible that the projections of the entire structure of the screw post 5 are on the mounting surface 3; no further restrictions are imposed here.

[0083] In this embodiment, multiple support rings after adhesive application can be stacked together. The weight of the upper support ring after stacking presses the panel 4 and the mounting surface 3 together. Figure 6 As shown.

[0084] Taking two stacked support rings as an example, the screw posts 5 on the upper support ring of the two adjacent support rings press against the panel 4 of the lower support ring, making the adhesive between the panel 4 and the mounting surface 3 more secure. At the same time, the stacked support rings are placed stably and are not easy to tip over, which facilitates packaging, batch transportation and storage during production. Moreover, there is no need to set up additional weights to weigh down the panel 4, saving costs.

[0085] According to an embodiment of the present invention, in a second aspect, a housing is also provided, including the aforementioned support ring; a panel 4, which is adhesively attached to the mounting surface 3; and a base 10, which is fixedly connected to the underside of the support ring.

[0086] In this embodiment, the bottom of the support structure protrudes from the second mounting cavity 2, and the base 10 has a clearance space 1001 corresponding to the support structure. Specifically, as shown... Figure 9As shown, the clearance space 1001 is a recessed clearance groove, which facilitates the assembly of the base 10 and the support ring, and allows the height of the position corresponding to the base 10 and the support structure to be set higher, without increasing the overall height of the base 10, thereby preventing the overall space of the shell from being set too high.

[0087] According to an embodiment of the present invention, a third aspect provides a manufacturing process for a housing, applied to the aforementioned housing, comprising:

[0088] Adhesive is placed on the mounting surface 3 of a support ring;

[0089] A panel 4 is placed above the mounting surface 3 to complete the fabrication of multiple housings;

[0090] One of the completed shells is stacked on top of another completed shell, so that the support structure of the upper shell is pressed onto the panel 4 of the lower shell.

[0091] The housing produced by this manufacturing process can be stacked on top of another housing during production, with the weight of the housing itself pressing down on the panel 4 of the lower housing to ensure the reliability of the panel 4 being glued to the support ring, without the need to set up a separate ballast weight to hold the panel 4 down, thus saving costs.

[0092] According to an embodiment of the present invention, in a fourth aspect, a household appliance is also provided, comprising: the aforementioned housing.

[0093] Specifically, the household appliance is a split-type rice cooker. The support ring of the split-type rice cooker has two stepped mounting cavities. The lower second mounting cavity 2 houses the bottom heating device, and the upper surface of the second mounting cavity 2 is equipped with a panel 4 for user operation. For example, the user can select various functions of the split-type rice cooker and control the heating temperature and heating time through the panel 4. The upper first mounting cavity 1 houses the side heating device, and the middle is used to place the pot body. In this way, when the pot body is placed in the first mounting cavity 1, the side heating device and the bottom heating device can heat the food in the pot body at the same time, so that the split-type rice cooker can realize the function of cooking rice.

[0094] As an alternative implementation, the household appliance can be an induction cooker or electric hot pot with a standalone function. In this case, the pot body is housed within the first mounting cavity 1 of the support ring of the induction cooker or electric hot pot, without including a side heating device. As an alternative implementation, the household appliance can be any other household appliance that requires both a support ring and a panel.

[0095] Specifically, the base of the split-type rice cooker is fixedly connected to the support ring via the aforementioned screw posts 5. By using the screw posts 5 on the support ring to fix the base and support ring together, without the need for additional separate screw posts 5, the overall structure of the household appliance becomes more compact, with fewer components.

[0096] As an alternative implementation, the base can be fixedly connected to the support ring by screws through additional screw posts, which would increase the number of screw posts. Alternatively, the base can be fixedly connected to the support ring by other fixing methods, such as welding or snap-fitting.

[0097] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
