Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to a drainage structure for a cooking device and a cooking device. Background Technology

[0002] Cooking appliances, such as ovens, steam ovens, or steam ovens, are convenient and efficient kitchen appliances that contain food in a closed space for cooking. During use, grease can easily accumulate on the inner walls of cooking appliances. If this grease is not cleaned regularly, it can produce unpleasant odors or cross-contamination of flavors, significantly impacting the user experience.

[0003] Currently, most cooking appliances are cleaned manually, which is time-consuming and labor-intensive. This is especially true for built-in or commercial cooking appliances with relatively large inner pot spaces, because the inner pot also contains heating elements for heating food, which can hinder manual cleaning, making manual cleaning of the cavity more difficult and prone to blind spots.

[0004] With the continuous optimization of cooking appliances, some now feature automatic cleaning functions. These appliances use a motor-driven fan to disperse water flow and splash it into the cavity for washing, or use a spray method to rinse the cavity. After automatic cleaning, residual wastewater needs to be drained from the inner pot. Therefore, a drain outlet is installed on the inner pot, with a filter screen inside. During cooking, the filter screen needs to be closed to prevent the loss of hot air from the inner pot or the backflow of odors from the drain pipe. Existing cooking appliances typically use a sealing cap to seal the filter screen when drainage is not needed, and remove the cap when drainage is required. This solution involves many drainage components, and if the sealing cap is lost or damaged due to improper storage, it needs to be replaced, increasing operating costs. Utility Model Content

[0005] Based on the aforementioned deficiencies in the prior art, the purpose of this utility model is to provide a drainage structure for a cooking device. The drainage structure includes an inner pot and an auxiliary cover detachably installed on the inner pot. The auxiliary cover has two installation methods, and by switching the installation method, it can achieve both sealing and filtering functions, which can reduce the number of parts. Furthermore, the auxiliary cover does not need to be removed during the switching between the two functions, and there is no risk of loss or accidental damage to the auxiliary cover due to removal, which is beneficial for cost control.

[0006] Therefore, the present invention provides the following technical solution.

[0007] This utility model provides a drainage structure for a cooking device, the drainage structure comprising:

[0008] The inner liner has a drain outlet and a cavity for holding food.

[0009] An auxiliary cover includes a sealing part and a filtering part, the filtering part having a plurality of filter holes; the auxiliary cover is detachably installed on the inner liner, and the auxiliary cover has a first installation method and a second installation method;

[0010] A drain pipe is connected to the inner liner, and the cavity can be connected to the cavity of the drain pipe through the drain outlet;

[0011] When the auxiliary cover is installed in the first installation method, the sealing part closes the drain outlet so that the pipe cavity is not in communication with the container cavity;

[0012] When the auxiliary cover is installed in the second installation method, the auxiliary cover is positioned above the drain outlet, and the cavity can communicate with the pipe cavity through the filter hole and the drain outlet.

[0013] Optionally, the filter section has a concave surface;

[0014] The inner liner is provided with a bottom plate, and the drain outlet is opened on the bottom plate. When the auxiliary cover is installed in the second installation method, at least part of the concave surface is spaced apart from the bottom plate so that a drain cavity is formed between the auxiliary cover and the bottom plate.

[0015] Optionally, the base plate is recessed downward at the drain outlet to form a drain groove, and the auxiliary cover covers the drain groove; when the auxiliary cover is installed in the second installation method, the drain cavity is formed between the auxiliary cover and the inner wall of the drain groove.

[0016] Optionally, the filter section also has an outwardly convex surface; when the auxiliary cover is installed in the first mounting manner, at least a portion of the outwardly convex surface can fit against the inner wall of the drainage groove.

[0017] Optionally, when the auxiliary cover is installed in the first installation method, the highest point of the auxiliary cover is lower than the highest point of the drainage channel;

[0018] When the auxiliary cover is installed in the second mounting manner, the highest point of the auxiliary cover is lower than the highest point of the base plate.

[0019] Optionally, the inner wall of the drainage channel is further recessed to form an installation groove, and an installation hole is provided on the bottom wall of the installation groove, and the part of the bottom wall of the installation groove other than the installation hole is defined as an annular abutment part.

[0020] The inlet end of the drain pipe is provided with an abutment boss and a threaded structure.

The threaded structure is screwed to a fastener located below the annular abutment part to install the drain pipe onto the base plate.

[0021] Optionally, the auxiliary cover has a plurality of notches in its circumferential direction for inserting tools or hands to pick up or put down the auxiliary cover.

[0022] Optionally, the auxiliary cover has a protrusion at the notch;

[0024] Optionally, the filter section is connected to the periphery of the closed section, and the plurality of filter holes are arranged in a ring array.

[0025] This utility model also provides a cooking device, including a heating component and a drainage structure as described above, wherein the heating component is used to heat food in the cavity.

[0026] This utility model has the following technical effects:

[0027] This utility model provides a drainage structure, which includes an inner liner and an auxiliary cover detachably mounted on the inner liner. The auxiliary cover has two installation methods, and by switching between the installation methods, it can achieve both sealing and filtering functions. When the auxiliary cover is installed in the first installation method, it can close the drain outlet, thus acting as a sealing cover and preventing the drain pipe cavity from communicating with the inner liner. When the auxiliary cover is installed in the second installation method, it covers the drain outlet, allowing the inner liner to communicate with the drain pipe cavity through the filter hole, allowing water in the inner liner to be discharged through the drain pipe, thus acting as a filtering cover. In this solution, the auxiliary cover can switch between sealing and filtering functions. Compared to the existing technology that uses a sealing cover for sealing and a filter screen for filtering, this solution only requires one cover (auxiliary cover), reducing the number of parts. Furthermore, regardless of whether it is in cooking mode or drainage mode, the auxiliary cover does not need to be removed, preventing loss or accidental damage to the auxiliary cover, which is beneficial for cost control.

[0049] In this utility model, "upper" and "lower" refer to... Figure 1 and Figure 5 The markings in the text shall prevail.

[0050] The following is based on Figures 1 to 8 This invention provides a detailed description of the cooking apparatus.

[0051] In this embodiment, the cooking apparatus includes a heating element (not shown in the figure), a cleaning system (not shown in the figure), and a drainage structure 100. The cooking apparatus includes, but is not limited to, ovens, steam ovens, and steam ovens, etc., devices that require heating and processing food in a sealed environment. Figure 1 and Figure 3 As shown, the drainage structure 100 includes an inner liner 1, an auxiliary cover 2, and a drain pipe 5. The inner liner 1 has a drain outlet 111 and a cavity 12 for containing food. The drain outlet 111 is located on the bottom plate 11 of the inner liner 1. During the cleaning process, the water from the cleaning system falls onto the bottom plate 11, facilitating rapid drainage from the drain outlet 111. Preferably, the drain outlet 111 is located at the center of the bottom plate 11, further accelerating the drainage speed. The drain pipe 5 is connected to the inner liner 1, and the cavity 12 can be connected to the cavity of the drain pipe 5 through the drain outlet 111.

[0052] When food needs to be cooked, it is placed in the cavity 12 of the inner pot 1. During or after the cleaning system washes the inner wall of the inner pot 1, the water in the cavity 12 is discharged through the drain outlet 111. It should be understood that the inner pot 1 can be a single component (such as a sheet metal part) or assembled from multiple components. Preferably, to facilitate the installation of the heating element in the inner pot 1, the inner pot 1 is composed of multiple component assemblies. For example, the inner pot 1 is assembled from a U-shaped plate and an L-shaped plate. The front of the inner pot 1 has an open structure, which can be closed by the door of the cooking device. Figure 3 and Figure 5 The partial structure of inner liner 1 is shown.

[0053] like Figure 4 As shown, the auxiliary cover 2 has a sealing part 21 and a filtering part 22, and the filtering part 22 has a plurality of filter holes 221. The auxiliary cover 2 is detachably installed on the inner liner 1, and the auxiliary cover 2 has a first installation method and a second installation method. Figures 1 to 4 As shown, when the auxiliary cover 2 is installed in the first installation method, the sealing part 21 seals the drain outlet 111, so that the pipe cavity and the container cavity 12 are not connected. The sealing method of the sealing part 21 on the drain outlet 111 includes, but is not limited to, covering or blocking. In this case, after the cooking device door is closed, the container cavity 12 can be in a sealed environment, and the cooking device can perform cooking. During the cooking process, the high-temperature air in the container cavity 12 will not escape from the drain outlet 111, thus avoiding heat loss and prolonging the cooking time. Furthermore, it also prevents odors from the drain pipe from entering the container cavity 12 from the drain outlet 111, causing backflow or cross-contamination of flavors. Figures 4 to 8As shown, when the auxiliary cover 2 is installed in the second installation method, the auxiliary cover 2 covers the drain outlet 111. The cavity 12 can communicate with the pipe cavity through the filter hole 221 and the drain outlet 111. In this case, during or after the water cleaning process of the cleaning system, the water in the cavity 12 can pass through the filter hole 221, be filtered, and enter the pipe cavity of the drain pipe 5 through the drain outlet 111 to realize drainage.

[0054] In the above technical solution, the auxiliary cover 2 is configured with two installation methods, and by switching the installation methods, it can achieve both sealing and filtering functions. When the auxiliary cover 2 is installed in the first installation method, the auxiliary cover 2 can close the drain outlet 111. In this case, the auxiliary cover 2 acts as a sealing cover, so that the cavity of the drain pipe 5 is not connected to the cavity 12. When the auxiliary cover 2 is installed in the second installation method, the auxiliary cover 2 covers the drain outlet 111, so that the cavity 12 can be connected to the cavity through the filter hole 221 and the drain outlet 111. The water in the cavity 12 can be discharged through the drain pipe 5. In this case, the auxiliary cover 2 acts as a filtering cover. In this solution, the auxiliary cover 2 can switch between sealing and filtering functions. Compared with the existing technology that uses a sealing cover for sealing and a filter screen for filtering, this solution only requires one cover (auxiliary cover 2), which reduces the number of parts. Furthermore, regardless of whether it is in cooking mode or drainage mode, that is, when switching between sealing and filtering functions, the auxiliary cover 2 does not need to be removed, which reduces the likelihood of loss or accidental damage to the auxiliary cover 2 and helps control costs.

[0055] In one embodiment, the filter section 22 has a concave surface 222, the inner liner 1 is provided with a bottom plate 11, and the drain outlet 111 is opened on the bottom plate 11. When the auxiliary cover 2 is installed in the second installation method, the concave surface 222 covers the drain outlet 111, and at least part of the concave surface 222 is spaced apart from the bottom plate 11, so that a drain cavity 3 is formed between the auxiliary cover 2 and the bottom plate 11. The cavity 12, the filter hole 221, the drain outlet 111 and the cavity of the drain pipe 5 are connected in sequence. In this way, during the drainage process of the inner liner 1, the water in the cavity 12 passes through the filter section 22 and enters the drain cavity 3, and then enters the cavity of the drain pipe 5 through the drain outlet 111 to realize drainage.

[0056] In one implementation, such as Figure 4As shown, the sealing part 21 and the filter part 22 are integrally formed, making the auxiliary cover 2 easy to process. The filter part 22 surrounds the outside of the sealing part 21, making full use of the space on the outer periphery of the sealing part 21 to arrange the filter part 22. The reasonable distribution of the filter part 22 and the sealing part 21 is conducive to the miniaturization design of the auxiliary cover 2. Of course, the positional relationship between the filter part 22 and the sealing part 21 is not limited to this. It is also possible that the filter part 22 is entirely located on one side of the sealing part 21. In this case, when the auxiliary cover 2 is installed in the first installation method, the filter part 22 may protrude more obviously from the inner wall of the inner liner 1, occupying the space of the cavity 12 and being unsightly. When the auxiliary cover 2 is installed in the second installation method, the sealing part 21 may also protrude more obviously from the inner wall of the inner liner 1, occupying the space of the cavity 12 and being unsightly.

[0057] In one embodiment, such as Figure 3 and Figure 6 As shown, the base plate 11 has a downwardly recessed drainage groove 112 at the drain outlet 111. When the auxiliary cover 2 is installed in the second installation method, the drainage cavity 3 is formed between the auxiliary cover 2 and the inner wall of the drainage groove 112. The drainage groove 112 is used to guide water to flow towards the drain outlet 111, thereby accelerating the drainage speed. Figure 2 and Figure 6 As shown, when the auxiliary cover 2 is installed on the base plate 11, the auxiliary cover 2 is embedded in the drainage groove 112. The position of the auxiliary cover 2 is inconspicuous, reducing the presence of the auxiliary cover 2 and improving the aesthetics of the inner liner 1.

[0058] Furthermore, such as Figure 2 , Figure 4 and Figure 8 As shown, one side of the filter section 22 forms a convex surface 223. (As indicated...) Figure 2 As shown, when the auxiliary cover 2 is installed in the first installation method, at least part of the convex surface 223 is in contact with the drain groove 112, and the end of the filter hole 221 facing the drain groove 112 is blocked by the surface wall of the drain groove 112. This prevents water droplets formed by the cooling steam during cooking from easily entering the filter hole 221 after falling onto the base plate 11. Furthermore, it prevents water from accumulating in the filter hole 221 and spreading everywhere, thus reducing the user's cleaning burden, during subsequent changes to the installation method of the auxiliary cover 2. Figures 4 to 8 As shown, when the auxiliary cover 2 is installed in the second installation method, the auxiliary cover 2 covers the drainage groove 112, and a drainage cavity 3 is formed between the auxiliary cover 2 and the inner wall of the drainage groove 112. Preferably, the outer convex surface 223 extends along the groove wall of the drainage groove 112 so that the outer convex surface 223 fits against the groove wall of the drainage groove 112 as much as possible.

[0059] In one specific embodiment, the other side of the filter section 22 is a concave surface 222, which surrounds the outside of the sealing section 21. The concave surface 222 and the convex surface 223 are opposite to each other. Thus, the auxiliary cover 2 has a roughly shell-like structure, which is simple and compact. Of course, the structure of the filter section 22 is not limited to this. The other side of the filter section 22 opposite to the convex surface 223 can also be a flat surface, an irregular surface, or other shapes. Preferably, both sides of the auxiliary cover 2 are roughly curved, so that there are no dead corners on the surface of the auxiliary cover 2, avoiding the accumulation of dirt.

[0060] In one implementation, such as Figure 4 As shown, the auxiliary cover 2 has several notches 24 on its circumference. The notches 24 are for inserting tools or hands to remove or place the auxiliary cover 2. When it is necessary to remove or place the auxiliary cover 2, the user can use a tool or directly insert their fingers into the notches 24 to remove or place the auxiliary cover 2.

[0061] Specifically, there are two, three or more notches 24. Users can use tools or their fingers to hook at least two of the notches 24 to clamp the auxiliary cover 2 and take it out.

[0062] Furthermore, such as Figure 4 , Figure 6 and Figure 8 As shown, the auxiliary cover 2 has a protrusion 25 at the notch 24, and the protrusion 25 is set one-to-one with the notch 24. When the auxiliary cover 2 is installed in the second installation method, the protrusion 25 abuts against the inner wall of the drain groove 112, and a water passage hole 4 is formed between the notch 24 and the inner wall of the inner liner 1. The protrusion 25 is used to prevent solids in the cavity 12 from entering the drain cavity 3 through the water passage hole 4. Specifically, since the circumferential sidewall of the auxiliary cover 2 has a notch 24, during the drainage process, solids (such as food residue) will flow into the water passage hole 4 formed between the notch 24 and the inner liner 1 with the water flow. In order to prevent solids from entering the drain outlet 111 and being discharged, and thus causing the drain outlet 111 to be blocked, this solution provides a protrusion 25 for each notch 24. The protrusion 25 is used to block solids from entering the drain cavity 3 through the water passage hole 4, blocking the solids outside the drain cavity 3, playing a filtering role, thereby preventing the drain outlet 111 from being blocked and increasing the cleaning difficulty for users.

[0063] Furthermore, such as Figure 4 As shown, all the notches 24 are evenly spaced along the circumference of the auxiliary cover 2, and the number of protrusions 25 is the same as the number of notches 24 and the two are set in a one-to-one correspondence.

[0064] In one implementation, such as Figure 4As shown, the filter section 22 is connected and disposed around the periphery of the closed section 21, and multiple filter holes 221 are arranged in a ring array, with multiple concentric ring arrays distributed sequentially in a direction away from the closed section 21. Figure 6 and Figure 8 As shown, when the auxiliary cover 2 is installed in the second installation method, the sealing part 21 is located above the drainage groove 112, and multiple concentric annular arrays are distributed sequentially from top to bottom. Some filter holes 221 are located above the drainage groove 112 so that some filter holes 221 do not come into contact with the water in the drainage chamber 3 when the drainage structure 100 drains water. Specifically, the cooking device also includes a water pump (not shown in the figure). The water pump provides power to the water circuit in the cooking device. For example, during drainage, the water pump provides power for drainage. In this solution, since some of the filter holes 221 do not contact the water in the drainage chamber 3 when the drainage structure 100 drains, as the water in the drainage chamber 3 flows into the drain pipe 5 through the drain outlet 111, the space occupied by the water in the drain pipe 5 increases, forcing the air in the drain pipe 5 to the surface of the water in the drainage chamber 3. Under the action of the air pressure on the surface of the water in the drainage chamber 3, the air is discharged from the filter holes 221 that do not contact the water in the drainage chamber 3 into the cavity 12. This helps to reduce the air content in the drain pipe 5, and ultimately reduces the amount of air entering the water pump, so as to avoid the water pump's efficiency being affected by a large amount of air in the water pump, or even causing the water pump to malfunction. In addition, when water droplets on the surface of the inner liner 1 fall onto the auxiliary cover 2, the air carried in the water droplets will be intercepted by the filter holes 221, further reducing the amount of air in the water entering the drain pipe 5.

[0065] In one implementation, such as Figure 2 As shown, when the auxiliary cover 2 is installed in the first installation method, the highest point of the auxiliary cover 2 is lower than the highest point of the drainage groove 112, so that the auxiliary cover 2 is completely hidden inside the drainage groove 112, making it difficult for the user to see the auxiliary cover 2 and improving the aesthetics of the inner liner 1. In a specific embodiment, the drainage groove 112 includes a first funnel section 1121 and a second funnel section 1122 connected sequentially from top to bottom. The slope of the circumferential sidewall of the first funnel section 1121 is less than the slope of the second funnel section 1122, and the highest point of the auxiliary cover 2 is lower than the highest point of the first funnel section 1121. In this scheme, the slope of the circumferential sidewall of the first funnel section 1121 is smaller, which is beneficial for better hiding the auxiliary cover 2.

[0066] like Figure 5 and Figure 6 As shown, when the auxiliary cover 2 is installed in the second installation method, the highest point of the auxiliary cover 2 is lower than the highest point of the base plate 11, so as to minimize the presence of the auxiliary cover 2 while meeting the space size requirements of the drainage cavity 3.

[0067] In one implementation, such as Figure 2 , Figure 3 and Figure 6 As shown, the inner wall of the drainage groove 112 is also recessed to form an installation groove 113. An installation hole 1132 is provided on the bottom wall of the installation groove 113, and the part of the bottom wall of the installation groove 113 other than the installation hole 1132 is defined as an annular abutment part 1131. That is, the bottom wall of the installation groove 113 is provided with an annular abutment part 1131, and an installation hole 1132 is formed in the middle of the annular abutment part 1131. The drainage structure 100 also includes a fastener 6; the inlet end of the drain pipe 5 is provided with an abutment boss 51 and a threaded structure 52, the drain pipe 5 passes through the mounting hole 1132, the abutment boss 51 is set in the mounting groove 113, and the bottom surface of the abutment boss 51 abuts against the annular abutment portion 1131; the threaded structure 52 is screwed to the fastener 6 located below the annular abutment portion 1131, the abutment boss 51 and the fastener 6 together clamp the annular abutment portion 1131 to install the drain pipe 5 on the base plate 11, making it easy to install and remove the drain pipe 5. Figure 2 As shown, when the auxiliary cover 2 is installed in the first installation method, the sealing part 21 seals the inlet 53 of the drain pipe 5 so that the cavity 12 is not connected to the drain pipe 5.

[0068] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described.
