Description

Technical Field

[0001] This utility model relates to the field of kitchenware, and in particular to a door assembly and a steam oven containing the same. Background Technology

[0002] Current steam ovens mostly use drawer-type water tanks, which are placed at the bottom, top, or side of the oven cavity, taking up space. Before cooking, users need to remove the water tank to add water, lacking a visual water level indicator. In summary, the water tanks in existing steam ovens have the following drawbacks:

[0003] 1. Space occupation: The water box will occupy the cavity space, reduce the effective volume of the cooking cavity, and affect the overall compactness of the steam oven;

[0004] 2. Inconvenient to operate: The water tank is not visible, making it impossible to directly observe the remaining water level, which may lead to cooking interruptions due to water shortage;

[0005] 3. Heat loss: The oven door inevitably absorbs heat during cooking, which leads to heat loss inside the cavity and causes the door temperature to rise, posing a safety hazard. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of existing steam ovens, such as the water tank being invisible, occupying a large space, and the door of the steam oven being hot, and to provide a door assembly and a steam oven containing the assembly.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] A door assembly for a steam oven, the door assembly including a door and a water tank, the door for opening or closing the steam oven, the water tank being mounted on the door and located inside the steam oven;

[0009] The door is made of a heat-resistant transparent material so that users can observe the water level in the water tank from the outside of the steam oven.

[0010] In this design, the door is made of a high-temperature resistant transparent material, making the water tank visible and reminding the user to add water before cooking, effectively preventing cooking interruptions due to lack of water. The integrated design of the door and water tank utilizes the heat that would otherwise be lost at the door, acting as a preheater and improving energy efficiency. At the same time, water's high specific heat capacity provides insulation, reducing the temperature of the door's outer surface. Furthermore, the water tank's installation method does not occupy the cooking cavity space of the steam oven, increasing the effective volume of the cooking cavity and making the entire unit more compact.

[0011] Preferably, a water level warning line is provided on the panel facing the outside of the steam oven or on the surface of the water tank facing the outside of the steam oven;

[0012] When the water level in the water tank is below the water level warning line, the water tank is in a state where it needs to be replenished.

[0013] In this solution, the aforementioned water level warning line facilitates observation of whether the water tank needs to be replenished, and allows for timely replenishment of the water tank.

[0014] Preferably, the water tank forms a viewing window, allowing the user to observe the interior of the steam oven through the door and the viewing window.

[0015] In this solution, the visualization window allows users to easily observe the water level in the water tank and the steaming / baking process of the food in the steam oven.

[0016] Preferably, the water box is U-shaped, and the opening of the water box forms a viewing window.

[0017] In this design, the U-shaped water tank lowers the center of gravity, enhancing structural stability. Furthermore, the U-shaped design allows for increased water tank volume while maintaining a viewing window, thus maximizing the amount of water it can hold.

[0018] Preferably, in the vertical direction, the cross-sectional area S of the water box is equal to the area of ​​the door panel. satisfy: S≤ .

[0019] In this design, the above-mentioned configuration maximizes the water tank volume, thereby maximizing the amount of water the water tank can hold. Preferably, the door assembly further includes a water replenishment component, which is installed on the door body. The water tank includes a water inlet component and a water tank body, with the water inlet component installed on the water tank body.

[0020] The water replenishment component can be connected to the water inlet component to replenish the water box.

[0021] In this solution, the water replenishment component is more securely installed on the door. If it were installed on the water box, it would increase the burden on the water box. In addition, the way the water replenishment component and the water inlet component are set up makes it easy to remove the water box and connect the water replenishment component to the water inlet component. When installing the water box, the water replenishment component can be connected to the water inlet component.

[0022] Preferably, the water replenishment component includes a pump and a water replenishment pipe connected together, and the water inlet component includes a water box cover and a water inlet pipe connected together. The water box cover is used to seal the water inlet of the water box body. The first end of the water inlet pipe is connected to the water box cover and extends toward the water replenishment pipe, and the second end of the water inlet pipe extends into the interior of the water box body.

[0023] When the water replenishment component is connected to the water inlet component, the water inlet at the first end of the water inlet pipe is connected to the water replenishment pipe, so that the water in the water replenishment pipe enters the water box body through the water outlet at the second end of the water inlet pipe.

[0024] In this design, the water tank cover is designed to prevent water from leaking out of the water tank. In addition, the first end of the water inlet pipe is connected to the water tank cover and extends toward the water supply pipe, while the second end of the water inlet pipe extends into the interior of the water tank body. This design not only utilizes the internal space of the water tank to save space occupied by the water inlet pipe, but also ensures that water enters the water tank through the water inlet pipe without causing a large impact on the water tank.

[0025] Preferably, a fixing device is provided on the side of the door facing the water box, and the fixing device is used to fix the water box to the door;

[0026] The fixing device includes a limiting plate and a fixing bracket; the limiting plate is located above the water box and forms a receiving space with the fixing bracket and the door, the receiving space being used to accommodate the water box;

[0027] Alternatively, the water box is U-shaped, and the fixing device includes a limiting plate and a fixing bracket; the limiting plate includes a first limiting plate and a second limiting plate, which are respectively set above the two ends of the opening of the water box, and form a receiving space with the fixing bracket and the door, the receiving space being used to receive the water box.

[0028] In this design, the limiting plate is located above the water box and forms a receiving space with the fixed bracket and the door. The receiving space is used to accommodate the water box, which can stably fix the water box to the door. The first limiting plate and the second limiting plate are respectively set above the two ends of the opening of the water box and form a receiving space with the fixed bracket and the door. The receiving space is used to accommodate the water box. The above arrangement makes the two ends of the water box well fixed and not easy to tilt.

[0029] Preferably, the fixing bracket includes a fixing bracket body and a rotating frame. The fixing bracket has a rotating frame at one end of the water box in the left-right direction. The rotating frame is used to fix the water box on the left or right side of the water box.

[0030] The first end of the rotating frame is rotatably mounted on the bottom of the fixed support body, and the second end of the rotating frame is detachably connected to the fixed support body via a connector.

[0031] When the second end of the rotating frame is in the detached state, the rotating frame can be rotated to release the fixing of the rotating frame to the water box;

[0032] When the second end of the rotating frame is in the installation state, the rotating frame, the main body of the fixed support, and the limiting plate form a receiving space.

[0033] In this solution, the fixed support body and the rotating frame are designed to allow for the disassembly and installation of the water box without completely disassembling the fixed support, making the operation simple and convenient.

[0034] This utility model also provides a steam oven, which includes a cabinet and the aforementioned door assembly, with the door assembly mounted on the cabinet.

[0035] The positive and progressive effects of this utility model are as follows: the door is made of a high-temperature resistant transparent material, making the water tank visible and reminding the user to add water before cooking, effectively avoiding cooking interruptions due to lack of water; the integrated design of the door and water tank utilizes the heat that would otherwise be lost at the door, serving as preheating water and improving energy efficiency; at the same time, water has a high specific heat capacity, which can act as insulation, reducing the temperature of the outer surface of the door; in addition, the installation method of the water tank does not occupy the cooking cavity space of the steam oven, increasing the effective volume of the cooking cavity and making the whole machine more compact.

[0060] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.

[0061] like Figure 1-5 As shown, this embodiment provides a door assembly 100 for a steam oven. The door assembly 100 includes a door 1 and a water tank 2. The door 1 is used to open or close the steam oven. The water tank 2 is installed on the door 1 and located inside the steam oven. The door 1 is made of a high-temperature resistant transparent material so that the user can observe the water level of the water tank 2 from the outside of the steam oven.

[0062] In this embodiment, the door 1 is made of a high-temperature resistant transparent material, making the water tank 2 visible and reminding the user to add water before cooking, effectively preventing cooking interruptions due to lack of water. The integrated design of the door 1 and the water tank 2 utilizes the heat that would otherwise be lost at the door 1, serving as preheating water and improving energy efficiency. At the same time, water has a high specific heat capacity, which can act as insulation, reducing the temperature of the outer surface of the door 1. In addition, the installation method of the water tank 2 does not occupy the cooking cavity space of the steam oven, increasing the effective volume of the cooking cavity and making the whole machine more compact.

[0063] It should be noted that in this embodiment, the door 1 can be made of transparent glass, and the water box 2 is also transparent to facilitate observation of the water level in the water box 2.

[0064] In other embodiments, the high-temperature resistant transparent material can be polycarbonate (PC), polyimide (PI), polyetheretherketone (PEEK), transparent ceramic, etc.; in addition, the water box 2 can also be opaque, in which case the water level of the water box 2 can be observed through the water inlet of the water box body 22.

[0065] A water level warning line is provided on the panel of the door 1 facing the outside of the steam oven or on the surface of the water tank 2 facing the outside of the steam oven; when the water level in the water tank 2 is below the water level warning line, the water tank 2 is in a state where water needs to be added.

[0066] In this embodiment, the water level warning line makes it easy to observe whether the water box 2 needs to be replenished, and thus replenish the water box 2 in a timely manner.

[0067] like Figure 2-4 As shown, the water tank 2 forms a visualization window 21, allowing the user to observe the interior of the steam oven through the door 1 and the visualization window 21.

[0068] In this embodiment, the visualization window 21 is designed to allow users to observe the water level in the water tank 2 and the steaming and baking status of the food in the steam oven.

[0069] It should be noted that the visualization window 21 is preferably located in the middle of the door body 1.

[0070] like Figure 4 As shown, water box 2 is U-shaped, and the opening of water box 2 forms a visualization window 21.

[0071] In this embodiment, the U-shaped water box 2 lowers the center of gravity of the water box 2, enhancing structural stability. In addition, the U-shaped water box 2 increases the volume of the water box 2 while retaining the visualization window 21, thereby increasing the amount of water it can hold.

[0072] It should be noted that the visualization window 21 allows the water level of water tank 2 to be observed from above.

[0073] like Figure 5 As shown, in the vertical direction, the cross-sectional area S of water box 2 and the area of ​​the panel of door 1 are... satisfy: S≤ .

[0074] In this embodiment, the above-mentioned arrangement can maximize the volume of water box 2, so as to maximize the amount of water that water box 2 can hold.

[0075] It should be noted that the total width of door 1 is... The total height is ,like Figure 4 As shown, the dimensions of water box 2 satisfy the following: in width, w≤ , ≤w, ≤ In terms of thickness, d≤ In terms of altitude, h≤ , ≤ , ≤ Wherein, w represents the overall width of the water box body 22. To visualize the width of window 21, The width of the water tank body 22 on one side of the visualization window 21. d represents the width of the water tank body 22 on the other side of the visualization window 21, d represents the thickness of the water tank body 22, and h represents the overall height of the water tank body 22. This is the distance between the bottom of the visualization window 21 and the bottom of the water tank body 22. The height of the visualization window 21.

[0076] Preferably, the door assembly 100 further includes a water replenishment component 11, which is installed on the door 1. The water box 2 includes a water inlet component 23 and a water box body 22, with the water inlet component 23 installed on the water box body 22. The water replenishment component 11 can be connected to the water inlet component 23 to replenish water to the water box 2.

[0077] In this embodiment, the water replenishment component 11 is more securely installed on the door 1. If it is installed on the water box 2, it will increase the burden on the water box 2. In addition, the arrangement of the water replenishment component 11 and the water inlet component 23 makes it convenient to remove the water box 2 and disconnect the water replenishment component 11 from the water inlet component 23. When installing the water box 2, the water replenishment component 11 can be connected to the water inlet component 23.

[0078] like Figure 2-5 As shown, the water replenishment component 11 includes a connected pump 111 and a water replenishment pipe 112, and the water inlet component 23 includes a connected water tank cover 231 and a water inlet pipe 232. The water tank cover 231 is used to seal the water inlet of the water tank body 22. The first end of the water inlet pipe 232 is connected to the water tank cover 231 and extends toward the water replenishment pipe 112, and the second end of the water inlet pipe 232 extends into the interior of the water tank body 22. When the water replenishment component 11 can be connected to the water inlet component 23, the water inlet at the first end of the water inlet pipe 232 communicates with the water replenishment pipe 112, so that water in the water replenishment pipe 112 enters the water tank body 22 through the water outlet at the second end of the water inlet pipe 232. It should be noted that the pump 111 serves as the power source for water distribution in the water replenishment component 11, and the pump 111 can also be replaced by other components that can provide water replenishment power, such as a motor.

[0079] In this embodiment, the water box cover 231 is designed to prevent water from flowing out of the water box 2. In addition, the first end of the water inlet pipe 232 is connected to the water box cover 231 and extends toward the water supply pipe 112, and the second end of the water inlet pipe 232 extends into the interior of the water box body 22. This design not only utilizes the internal space of the water box 2 to save the space occupied by the water inlet pipe 232, but also ensures that water enters the water box 2 through the water inlet pipe 232 without causing a large impact on the water box 2.

[0080] It should be noted that most of the water inlet pipe 232 is located inside the water box body 22.

[0081] like Figure 3-4 As shown, a fixing device 3 is provided on the side of the door 1 facing the water box 2. The fixing device 3 is used to fix the water box 2 to the door 1.

[0082] The fixing device 3 includes a limiting plate and a fixing bracket 33; the limiting plate is located above the water box 2 and forms a receiving space with the fixing bracket 33 and the door 1, the receiving space being used to receive the water box 2;

[0083] Alternatively, the limiting plate includes a first limiting plate 31 and a second limiting plate 32. The first limiting plate 31 and the second limiting plate 32 are respectively disposed above the two ends of the opening of the water box 2, and form a receiving space with the fixed bracket 33 and the door 1. The receiving space is used to receive the water box 2. In this embodiment, the limiting plate is located above the water box 2 and forms a receiving space with the fixed bracket 33 and the door 1. This arrangement can stably fix the water box 2 to the door 1. The first limiting plate 31 and the second limiting plate 32 are respectively disposed above the two ends of the opening of the water box 2 and form a receiving space with the fixed bracket 33 and the door 1. This arrangement ensures that the two ends of the water box 2 are well fixed and are not prone to tilting.

[0084] It should be noted that the first limiting plate 31 and the second limiting plate 32 are tightly fitted to both ends of the opening of the water box 2; a preset gap may also be left between the first limiting plate 31 and the second limiting plate 32 and both ends of the opening of the water box 2 to facilitate the installation and disassembly of the water box 2. Figure 3-5 As shown, the fixed bracket 33 includes a fixed bracket body 331 and a rotating frame 332. The fixed bracket 33 has a rotating frame 332 at one end in the left-right direction of the water box 2. The rotating frame 332 is used to fix the water box 2 on the left or right side of the water box 2.

[0085] The first end of the rotating frame 332 is rotatably mounted on the bottom of the fixed support body 331, and the second end of the rotating frame 332 is detachably connected to the fixed support body 331 via the connector 333.

[0086] When the second end of the rotating frame 332 is in the disassembled state, the rotating frame 332 can rotate to release the fixing of the rotating frame 332 to the water box 2;

[0087] When the second end of the rotating frame 332 is in the installation state, the rotating frame 332, the fixed support body 331 and the limiting plate form a receiving space.

[0088] In this embodiment, the fixed bracket body 331 and the rotating frame 332 are provided so that the water box 2 can be disassembled and installed without completely disassembling the fixed bracket 33, making the operation simple and convenient.

[0089] It should be noted that in other embodiments, the water box 2 is disassembled and installed from the end where the rotating frame 332 is located. In addition, if the rotating frame 332 is located on the right side of the water box 2, when the water box 2 needs to be pulled out, the connector 333 is removed, the rotating frame 332 can be rotated downwards, the water box 2 can be pulled out to the right, and when the water box 2 is returned to the left, the water inlet pipe 232 and the water supply pipe 112 are connected to achieve water pipe connection, and under the limitation of the fixing device 3, water overflow is prevented. After the water box 2 is placed, the rotatable plate is rotated to the vertical direction and the connector 333 is fastened to fix the water box 2.

[0090] In this embodiment, the rotating frame 332 is located at the end away from the fixed support 33 that fixes the water box cover 231.

[0091] This utility model also provides a steam oven, which includes a cabinet and the aforementioned door assembly 100, with the door assembly 100 mounted on the cabinet.

[0092] The steam oven can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the steam oven to perform corresponding operations, thereby realizing intelligent control of the steam oven and improving the user experience.
