Abstract
Description
Technical Field
[0001] This application relates to the technical field of steaming and baking equipment, and more particularly to a steam oven. Background Technology
[0002] A steam oven is a kitchen appliance that combines steaming and baking functions. It uses a steaming box inside the cavity, which typically consists of a lid and a body. The lid usually fits snugly onto the body, creating a space for steaming and cooking inside the steaming box, while the space outside is used for baking.
[0003] When steam is injected into the steam oven, it can easily escape into the cavity through the gap between the lid and the body. Related technologies typically use a sealing strip at the joint between the lid and body to seal the gap and prevent steam escape. This method is effective for moderate steam volumes, but when the steam volume is large, the resulting pressure can push the lid upwards, creating a larger gap between the lid and body, leading to significant steam overflow. Steam overflow not only affects the cooking performance of the steam oven and reduces energy efficiency, but can also damage other internal components, shortening the oven's lifespan. It also causes inconvenience and safety hazards for users. Utility Model Content
[0004] To address the shortcomings of related technologies, this application provides a steam oven that provides a skirt around the outer periphery of the lid, which is positioned within a limiting portion on the shelf. This utilizes the shelf to limit and constrain the lid, preventing it from being lifted by steam and avoiding steam from escaping through the gap between the lid and the oven body, thus reducing the steaming and cooking effect of the oven.
[0005] This application provides a steam oven, comprising:
[0006] The housing has a first heating chamber defined inside it, and a first opening communicating with the first heating chamber is formed on the housing; the first opening is positioned facing the front of the housing.
[0007] A door, which is openable and closable at the first opening, is used to open or close the first heating chamber;
[0008] A steaming box, disposed within the first heating chamber; the steaming box includes:
[0009] The box body is defined by having a second heating chamber with an opening facing the top of the box body;
[0010] The lid is snapped onto the opening of the second heating chamber; a sealing element is provided at the joint between the lid and the box body; and a skirt is provided on the outer edge of the lid.
[0011] A shelf is located inside the first heating chamber, and a limiting part is formed on the shelf for inserting the skirt; the limiting part is used to prevent the lid from moving along the height direction of the box body.
[0012] This technical solution involves setting a skirt around the outer periphery of the lid, with the skirt positioned within the limiting part on the shelf. This utilizes the shelf to limit and constrain the lid, preventing it from being lifted by steam and avoiding steam from escaping from the gap between the lid and the body, thus reducing the steaming and cooking effect of the steamer.
[0013] In some embodiments, the outer periphery of the box body is provided with an extension portion, which is located near the opening of the second heating chamber; at least a portion of the extension portion is provided corresponding to the skirt along the height direction of the box body, and the portion of the extension portion corresponding to the skirt is located within the limiting portion.
[0014] This technical solution provides an extension on the outer periphery of the box body, with part of the extension located within a limiting part, so that the limiting part can be used to position the steaming box within the first heating chamber.
[0015] In some embodiments, the dimension of the limiting part along the height direction of the box is X, and the distance from the skirt to the extension along the height direction of the box is Z. X and Z satisfy the relationship: X≤Z.
[0016] This technical solution ensures that the skirt and the extension can be simultaneously located within the limiting part by making the dimension X of the limiting part along the height direction of the box body smaller than the distance Z of the skirt along the height direction of the box body to the extension part.
[0017] In some embodiments, the inner wall of the box is inclined toward the center of the box along the height direction of the box, and the outer edges of the seal and the box cover are located in the second heating chamber.
[0018] This technical solution involves tilting the inner wall of the box along its height, so that the gap between the lid and the box becomes smaller as the lid moves downwards, thus providing a better sealing effect.
[0019] In some embodiments, the limiting portion has an upper edge and a lower edge along the height direction of the box body, and the skirt is located below the upper edge and above the lower edge.
[0020] This technical solution positions the skirt edge between the upper and lower edges of the limiting part, thereby using the limiting part to constrain the skirt edge.
[0021] In some embodiments, the distance from the upper edge of the skirt along the height direction of the box body is A, and the effective working range of the seal along the height direction of the box body is B. A and B satisfy the relationship: A≤B.
[0022] This technical solution ensures that the distance A from the upper edge of the skirt along the height direction of the box body is less than or equal to the effective working range B of the seal along the height direction of the box body, so that the seal still has a good sealing effect when the box cover moves within a small range.
[0023] In some embodiments, the skirt is located outside the second heating chamber and above the seal.
[0024] This technical solution positions the skirt outside the second heating chamber and above the seal, so that when the limiting part restricts the movement of the skirt, it can indirectly limit the movement of the seal.
[0025] In some embodiments, the seal has an insertion portion that is disposed along the length of the seal; the cover has a fixing portion that is disposed at the outer edge of the cover and is inserted into the insertion portion so that the seal is installed on the cover.
[0026] This technical solution involves providing an insertion part in the sealing element and a fixing part in the box cover, with the fixing part inserted into the insertion part to install the sealing element onto the box cover.
[0027] In some embodiments, two shelves are provided, which are correspondingly located on opposite sides of the steaming box, and two skirts are provided, which correspond one-to-one with the two shelves.
[0028] This technical solution increases the constraint effect of the shelves on the lid by setting two shelves, which are positioned on opposite sides of the steaming box, and by setting two skirts, which are positioned one-to-one with the two shelves.
[0029] In addition, this application also provides a steam oven, comprising:
[0030] The housing has a first heating chamber defined inside it, and a first opening communicating with the first heating chamber is formed on the housing; the first opening is positioned facing the front of the housing.
[0031] A door, which is openable and closable at the first opening, is used to open or close the first heating chamber;
[0032] A steaming box, disposed within the first heating chamber; the steaming box includes:
[0033] The box body has a second heating chamber; a second opening is formed on the box body and is positioned facing the top of the box body.
[0034] The lid is snapped onto the second opening to open or close the second heating chamber; when the lid is snapped onto the box body, there is a fitting gap between the lids; the outer periphery of the lid is provided with a skirt, which is located above the fitting gap.
[0035] A sealing element, which is installed on the box cover, is located at the mating gap and is used to seal the mating gap;
[0036] A shelf is located inside the first heating chamber, and a limiting part is formed on the shelf for inserting the skirt; the limiting part is used to prevent the lid from moving along the height direction of the box body.
[0037] This technical solution involves setting a skirt around the outer periphery of the lid, with the skirt positioned within the limiting part on the shelf. This utilizes the shelf to limit and constrain the lid, preventing it from being lifted by steam and avoiding steam from escaping from the gap between the lid and the body, thus reducing the steaming and cooking effect of the steamer.
[0038] In the above embodiments, a steam oven has a good steaming and cooking effect, and the steam is not easy to leak. Moreover, the overall structure is simple and easy to arrange. By setting a skirt on the outer periphery of the lid, the skirt is located in the limiting part on the shelf, so as to use the shelf to limit and constrain the lid, prevent the lid from being pushed up by the steam, and avoid the steam from escaping from the gap between the lid and the body, thereby reducing the steaming and cooking effect of the steam oven.

[0060] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.
[0061] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.
[0062] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.
[0063] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.
[0064] The steam oven provided in this application can have various implementation forms. Figure 1 This is one specific embodiment of the steam oven of this application.
[0065] like Figure 1 As shown, the steam oven includes a housing 100, which forms the overall appearance of the steam oven. The housing 100 has a top and a bottom. The top and bottom of the housing 100 are opposite ends. The length of the housing 100 is from the top to the bottom. The left and right sides of the housing 100 are opposite sides. The length of the housing 100 is from the left to the right. The front and rear sides of the housing 100 are opposite sides. The thickness of the housing 100 is from the front to the rear.
[0066] like Figure 2 As shown, the box 100 has a first heating cavity 101 defined inside. The first heating cavity 101 serves as a storage space for placing components such as the shelf 300 and the steam box 200, and also serves for baking and cooking food.
[0067] A first opening is formed on the housing 100, and the first opening is positioned facing the front of the housing 100; the first opening is connected to the first heating chamber 101 so that the user can place an item into the first heating chamber 101 or take an item out of the first heating chamber 101 through the first opening.
[0068] The steam oven includes a door, which is provided at the first opening in an openable manner for opening or closing the first heating chamber 101.
[0069] In practical applications, the cabinet door is usually rotatably connected to the cabinet body 100 to facilitate opening and closing. The rotation axis of the cabinet door can be set along the height of the cabinet body 100, allowing the door to rotate vertically. Alternatively, the rotation axis can be set along the length of the cabinet body 100, allowing the door to rotate horizontally.
[0070] like Figure 1 , Figure 3 and Figure 4As shown, the steam oven includes a steam box 200, which is disposed within the first heating chamber 101 and is used for steaming cooking. The heat source for the steam box 200 can come from the first heating chamber 101 or from a heating component connected to the steam box 200.
[0071] It should be noted that the steam box 200 can be separated from the first heating chamber 101.
[0072] When the heat source for the steam oven 200 comes from the first heating chamber 101, the steam oven 200 itself is not connected to the heating element. The heating element is connected to the oven body 100. The heating element heats the first heating chamber 101, and the steam oven 200 absorbs the heat from the first heating chamber 101, thus raising the internal temperature of the steam oven 200 and performing steaming cooking. This can also be understood as the heating element indirectly heating the steam oven 200 through the first heating chamber 101. It should be noted that in this case, the steam oven cannot perform steaming cooking alone.
[0073] When the heat source of the steam box 200 comes from the heating component connected to the steam box 200, the steam box 200 and the cabinet 100 are respectively connected to the heating component. The heating component connected to the steam box 200 is used to heat the steam box 200, and the heating component connected to the cabinet 100 is used to heat the first heating chamber 101. The two heating components can work at the same time or work separately. That is, the steam oven can only perform steaming cooking, only perform baking cooking, or perform both steaming cooking and baking cooking at the same time.
[0074] The heating method of the steam box 200 is existing technology in this field and will not be described in detail here.
[0075] In this embodiment, the height direction of the steaming box 200 is the same as the height direction of the steam oven, the front-to-back direction of the steaming box 200 is the same as the front-to-back direction of the steam oven, and the left-to-right direction of the steaming box 200 is the same as the left-to-right direction of the steam oven.
[0076] like Figure 3 , Figure 4 and Figure 6 As shown, the steam box 200 includes a box body 220, which defines a second heating chamber 223 for steaming and cooking. A second opening is formed on the box body 220, which faces the top of the box body 100 and communicates with the second heating chamber 223 so that items inside the second heating chamber 223 can be placed or removed through the second opening.
[0077] like Figure 4As shown, the second heating chamber 223 is provided with a partition 240, which divides the second heating chamber 223 into a storage area and a water holding area. The storage area is located above the partition 240 and is used to hold food and items that need to be steamed or cooked. The water holding area is located below the partition 240 and is used to hold water. Items in the second heating chamber 223 are placed on the partition 240.
[0078] The partition 240 is provided with several ventilation holes, which are set along the height of the steaming box 200. The ventilation holes are used to connect the storage area and the water holding area so that the steam generated in the water holding area can enter the storage area through the ventilation holes to heat the food.
[0079] like Figure 4 and Figure 6 As shown, the box body 220 is provided with an operation part 222. The operation part 222 is located outside the extension 221. The operation part 222 is provided at least on the side of the box body 220 facing the first opening, so that the user can place the box body 220 into the first heating chamber 101 or remove the box body 220 from the first heating chamber 101 through the operation part 222.
[0080] In some embodiments, the operating part 222 is part of the extension 221 to simplify the structure of the box 220 and facilitate the manufacture of the box 220.
[0081] like Figure 3 and Figure 4 As shown, the steaming box 200 includes a lid 210, which is snap-fitted onto the second opening for opening or closing the second heating chamber 223. The lid 210 and the box body 220 are positioned opposite each other along the height direction of the steaming box 200, with the lid 210 located above the box body 220.
[0082] like Figure 3 , Figure 4 and Figure 7 As shown, a handle 211 is installed on the lid 210 to facilitate operation of the lid 210 by the user. The handle 211 is located above the lid 210. The user can use the handle 211 to fasten the lid 210 onto the box body 220, or to separate the lid 210 from the box body 220.
[0083] In some embodiments, two handles 211 are provided, with the two handles 211 corresponding to the left and right sides of the steam oven. This not only increases the user's flexibility in operating the lid 210, but also enhances the aesthetics of the lid 210.
[0084] like Figure 1 and Figure 9As shown, a shelf 300 is provided in the first heating chamber 101, and a limiting part 320 is formed on the shelf 300. The limiting part 320 is used to constrain the box body 220 to position the steam box 200 in the first heating chamber 101.
[0085] like Figure 4 and Figure 6 As shown, the box body 220 is provided with an extension 221, which is located at the outer edge of the second opening. At least a portion of the extension 221 is located within the limiting portion 320 so that the shelf 300 limits and constrains the box body 220.
[0086] In some embodiments, such as Figure 9 and Figure 11 As shown, there are two shelves 300, which are arranged opposite each other along the length of the steam oven. The steam box 200 is arranged between the two shelves 300 along the length of the steam oven, so that the two shelves 300 limit and constrain the two sides of the steam box 200 along the length of the steam oven.
[0087] The distance between the two shelves 300 along the length of the steam oven is L1, the distance between the left and right side walls of the first heating cavity 101 is L2, and the distance between the steam box 200 along the length of the steam oven is L3. L3, L2 and L1 satisfy the following relationship: L3>L1, L3≤L2, L1≤L2.
[0088] If L1>L2, then the two shelves 300 cannot be placed in the first heating chamber 101 at the same time.
[0089] If L3 > L2, then the steam box 200 cannot be placed in the first heating chamber 101.
[0090] If L3≤L1, then the limiting part 320 on the shelf 300 cannot limit the steam box 200.
[0091] In some embodiments, the extension 221 extends along the outer edge of the second opening, and the two extension ends of the extension 221 overlap each other to increase the firmness of the connection between the extension 221 and the box body 220, facilitate the manufacture of the extension 221, and also increase the aesthetics of the box body 220.
[0092] like Figure 11 As shown, the shelf 300 is provided with multiple limiting parts 320, which are distributed along the height direction of the steam box 200 so that the extension part 221 can cooperate with the limiting parts 320 of different heights according to the position of the steam box 200 in the height direction of the steam box 200, thereby realizing the adjustment of the position of the steam box 200 in the height direction of the steam box 200.
[0093] The limiting part 320 can also limit the height of the steam box 200 in the box body 220. The shelf 300 is used to limit the position of the steam box 200 in the first heating cavity 101 to increase the firmness and reliability of the steam box 200 in the first heating cavity 101.
[0094] In some embodiments, the shelf 300 is provided with a plurality of storage portions 310, which are distributed along the height direction of the steam box 200, and two adjacent storage portions 310 together define a limiting portion 320 along the height direction of the steam box 200.
[0095] When the lid 210 is fastened to the second opening, a gap will inevitably be generated at the joint between the box body 220 and the lid 210. Steam in the second heating chamber 223 can easily escape from the gap, reducing the steaming effect of the steam box 200.
[0096] In some embodiments of this application, a sealing element 230 is provided at the fitting gap to seal the fitting gap formed by the box body 220 and the box cover 210, so as to prevent the steam in the second heating chamber 223 from escaping from the gap between the box body 220 and the box cover 210 and thus reducing the steaming and cooking effect of the steam box 200.
[0097] like Figure 10 As shown, when the lid 210 is fastened to the body 220, the outer edge of the lid 210 is located inside the second heating chamber 223, and the sealing member 230 is also located inside the second heating chamber 223. The sealing member 230 abuts against the inner wall of the second heating chamber 223 to seal the mating gap.
[0098] The inner wall of the box body 220 is generally inclined towards the center of the box body 220 along the height direction of the box body 220, that is, the inner wall of the box body 220 increases from bottom to top along the height direction of the lid 210. The further the lid 210 moves downward along the height direction of the box body 220, the smaller the gap between the lid 210 and the box body 220, and the better the sealing effect of the seal 230.
[0099] It should be noted that when the seal 230 is in operation, it is typically deformed by compression to fill the mating gap. Theoretically, the closer the lid 210 is to the bottom of the box body 220, the better the sealing effect of the seal 230. However, in practice, if the seal 230 is excessively deformed by compression, it may lose its elasticity, which will reduce the sealing effect. This is common knowledge in the field and will not be elaborated further.
[0100] like Figure 5As shown, a fixing part 213 is provided at the outer edge of the box cover 210. The fixing part 213 protrudes from the outer edge of the box cover 210 and extends along the outer edge of the box cover 210. The fixing part 213 is connected to the sealing member 230 so that the sealing member 230 is installed on the box cover 210.
[0101] like Figure 12 As shown, the sealing member 230 is provided with an insertion part 232, which is used for the insertion of the fixing part 213. The fixing part 213 is inserted into the insertion part 232 so that the sealing member 230 and the cover 210 are connected to each other.
[0102] In some embodiments, the insertion portion 232 is a mounting groove that extends along the length of the seal 230 to increase the firmness of the connection between the seal 230 and the cover 210.
[0103] like Figure 5 As shown, the cover 210 is provided with a receiving portion 214, which is located above the fixing portion 213. The receiving portion 214 is used to receive the sealing member 230, so that part of the sealing member 230 is provided in the receiving portion 214. This not only increases the firmness of the connection between the sealing member 230 and the cover 210, but also increases the sealing effect of the sealing member 230.
[0104] like Figure 12 As shown, the seal 230 is provided with a mounting part 233, which is inserted into the receiving part 214. The mounting part 233 is located above the insertion part 232. When the fixing part 213 is inserted into the insertion part 232, the mounting part 233 is inserted into the receiving part 214.
[0105] The seal 230 is made of a relatively soft material such as rubber or silicone.
[0106] like Figure 12 As shown, the sealing element 230 is provided with a sealing part 231, which is in contact with the peripheral wall of the second heating chamber 223 to seal the fitting gap between the cover 210 and the box body 220.
[0107] like Figure 6 As shown, the box body 220 is provided with a shelf 224, which is located inside the second heating chamber 223. The shelf 224 is located near the second opening and is used to limit the matching position of the lid 210 with the box body 220 in the height direction. The shelf 224 prevents the lid 210 from moving towards the bottom of the box body 220.
[0108] It should be noted that the shelf 224 also limits and constrains the seal 230 in the height direction of the box 220 to a certain extent, preventing the seal 230 from continuing to move towards the bottom of the box 220.
[0109] Although the sealing element 230 at the mating point between the lid 210 and the body 220 can seal the gap between them, when there is a lot of steam in the second heating chamber 223, the steam can easily exert an upward force on the lid 210, causing it to be lifted up. This reduces the sealing effect of the sealing element 230, leading to steam leakage and reducing the steaming and cooking effect of the steam box 200.
[0110] Based on this, in this application, if Figure 5 and Figure 8 As shown, a skirt 212 is provided at the outer edge of the lid 210, so that the skirt 212 is located inside the limiting part 320, so that the shelf 300 can limit and constrain the lid 210, preventing the lid 210 from moving significantly along the height direction of the steam box 200, avoiding the lid 210 from separating from the box body 220, which would increase the gap between the parts and reduce the sealing effect of the sealing element 230.
[0111] When the lid 210 moves upward under the action of steam, the skirt 212 is located inside the limiting part 320, which prevents the skirt 212 from moving upward, thereby preventing the lid 210 from moving upward.
[0112] like Figure 4 As shown, the skirt 212 is provided on the outer periphery of the box cover 210 so that the skirt 212 is located within the limiting portion 320; as Figure 8 As shown, the skirt 212 is located above the receiving portion 214, so that the skirt 212 is above the seal 230, thereby placing the skirt 212 above the mating gap and ensuring the sealing effect of the seal 230.
[0113] Two skirts 212 are provided, and the two skirts 212 are provided on both sides of the lid 210 along the length of the steam oven. The two skirts 212 are provided one-to-one with the two shelves 300. The two skirts 212 are provided within the limiting part 320 of the two shelves 300 to increase the blocking effect of the shelves 300 on the lid 210.
[0114] It should be noted that the skirt 212 and the portion of the extension 221 provided in the limiting part 320 are provided correspondingly along the height direction of the steam box 200, so that the limiting part 320 can simultaneously limit the lid 210 and the box body 220. This not only restricts the placement position of the steam box 200 in the first heating chamber 101, but also restricts the lid 210 from moving too much along the vertical direction of the steam oven.
[0115] It should be noted that the limiting part 320 is provided with an insertion part, which is positioned facing the first opening. The skirt 212 and the extension 221 are located inside the limiting part 320 along the thickness direction of the steam oven.
[0116] In this application, the limiting part 320 can not only position the steam box 200 in the first heating chamber 101, but also constrain the lid 210 to prevent the lid 210 from moving upward.
[0117] like Figure 13 As shown, the height of the limiting part 320 along the vertical direction of the steam oven is X, and the distance from the skirt 212 to the extension 221 is Z. X and Z satisfy the relationship: X≤Z, so that the skirt 212 and the extension 221 can be provided in the same limiting part 320 at the same time.
[0118] If X>Z, then the skirt 212 and the extension 221 cannot be provided in the same limiting part 320 at the same time.
[0119] The limiting part 320 has an upper edge and a lower edge along the height direction of the steam oven. The skirt 212 is located below the upper edge and above the lower edge, so that the skirt 212 is located within the limiting part 320. Similarly, the extension part 221 is located below the upper edge and above the lower edge, so that the extension part 221 is located within the limiting part 320.
[0120] In practical applications, in order to ensure the smoothness of the skirt 212 and the extension 221 within the limiting part 320, the skirt 212 is usually a certain distance away from the upper edge of the limiting part 320. The distance from the skirt 212 to the upper edge of the limiting part 320 is A. The lid 210 can move slightly within a distance of A along the height direction of the steaming box 200.
[0121] The effective working range of the seal 230 is B, where A and B satisfy the relationship: A≤B, so that the seal 230 can still have a good sealing effect when the lid 210 moves slightly along the height direction of the steam box 200.
[0122] It should be noted that the effective working range of the seal 230 refers to the distance that the seal 230 can move along the height direction of the steam box 200 while ensuring the sealing effect. That is, within the range of height B, the seal 230 has a good sealing effect on the mating gap.
[0123] In some embodiments, the bottom of the extension 221 is placed at the lower edge of the limiting part 320 so that the limiting part 320 supports the box body 220, which can reduce the pressure of the steam box 200 on the bottom wall of the first heating chamber 101, and also increase the firmness of the steam box 200 in the first heating chamber 101, preventing the steam box 200 from moving randomly in the first heating chamber 101 under the action of steam.
[0124] In the aforementioned steam oven, a skirt 212 is provided on the outer periphery of the lid 210, and the skirt 212 is located within the limiting part 320 on the shelf 300. The shelf 300 is used to limit and constrain the lid 210 in the height direction of the steam oven, preventing the lid 210 from displacing significantly along the height direction of the steam box 200 under the action of steam. This also prevents steam from escaping from the gap between the lid 210 and the box body 220, thus reducing the steaming and cooking effect of the steam box 200.
[0125] The steam oven described above has good steaming and cooking effects, and steam is not easy to leak. Moreover, the steam box 200 has high reliability in the first heating chamber 101.
