Description

Technical Field

[0001] The embodiments of the present application relate to household appliance technology, and more particularly to a steam oven. Background Art

[0002] With the development of people's economic level, more and more household appliances are used in ordinary families. As a commonly used kitchen appliance, steam ovens are becoming more and more popular.

[0003] In the related art, a steam oven includes a water tank, a steam generator, a return pump and an inner pot. The steam generator is connected to the water tank and the return pump, and the steam generator is connected to the inner pot. The liquid in the water tank flows into the steam generator. The steam generated by the operation of the steam generator enters the inner pot to heat the food. The residual water after the operation of the steam generator ends is transported to the water tank through the return pump.

[0004] However, the return pump makes a lot of noise when running and there is a lot of condensed water in the inner tank. Summary of the invention

[0005] The embodiment of the present application provides a steam oven with lower noise and less liquid in the inner pot.

[0006] In some embodiments, a steam oven is provided, comprising:

[0007] A housing, wherein the housing is provided with a receiving cavity;

[0008] An inner pot, the inner pot is located in the accommodating cavity, the inner pot is configured with a cooking cavity, the inner pot is configured with a first opening communicating with the cooking cavity, and the inner pot is configured with a first steam port communicating with the cooking cavity;

[0009] Steam system, the steam system is located in the containing cavity, and the steam system includes:

[0010] An evaporation plate, the evaporation plate is embedded in the inner bottom of the cooking cavity;

[0011] A steam generator, the steam generator is located in the accommodating cavity, and the steam generator includes:

[0012] The body is configured to heat the liquid into steam;

[0013] A steam pipe, the steam pipe is connected to the body, the steam pipe is provided with a second steam port, and the second steam port is connected to the first steam port;

[0014] A water pipe is connected with the main body, and the water pipe is structured with a water inlet, which is located above the first opening. When the water inlet is connected with the first opening, the liquid in the main body flows into the cooking cavity through the water pipe, the water inlet and the first opening, and the evaporation plate is configured to heat the liquid in the cooking cavity into steam.

[0015] In this way, based on the principle that liquid will flow downward under the action of gravity, the water inlet is located above the first opening. When the water inlet is connected to the first opening, the residual liquid in the body will flow into the cooking cavity through the water pipe, the water inlet and the first opening in sequence under the action of gravity. The residual liquid will gather at the bottom of the inner pot. Moreover, based on the principle that steam forms water when it is cooled, and water will flow downward under the action of gravity, the condensed water in the inner pot will gather at the bottom of the inner pot. The evaporation plate is located at the bottom, which can evaporate the residual liquid and condensed water to a large extent. The technical problems of high noise during the operation of the return pump and high condensed water in the inner pot are effectively solved, and the purpose of low noise and low condensed water in the inner pot is achieved.

[0016] In some embodiments, a steam oven is provided, wherein the water inlet is located on a side of the water pipe that is away from the body along the extension direction, and the extension direction of the water pipe forms an angle with the ground;

[0017] The water inlet is communicated with the first opening through the inner cavity of the first pipe, and the main body is located above the first pipe.

[0018] In this way, under the action of gravity, the residual liquid in the body can be drained to a greater extent.

[0019] In some embodiments, a steam oven is provided, wherein 1 degree < included angle < 5 degrees.

[0020] Thus, when the angle b is less than 1 degree, the inclination angle is small, which is not conducive to the outflow of the residual liquid in the body.

[0021] When the angle b is greater than 5 degrees, the inclination angle is relatively large. When improvements are made on the basis of the zero angle in the steam generator in the related art, the changes are relatively large, and the mold needs to be reprocessed, which is costly.

[0022] In some embodiments, a steam oven is provided, wherein a first control valve is disposed on the first pipeline, and the first control valve is configured to control the connection or disconnection between the water port and the first opening.

[0023] In this way, it is convenient to control whether the water outlet is connected or not connected with the first opening.

[0024] In some embodiments, a steam oven is provided, wherein the evaporation tray is located in the middle area of ​​the bottom wall of the inner container, and the height of the bottom wall of the inner container increases along the direction from the evaporation tray to the side wall of the inner container.

[0025] In this way, based on the principle that water will flow downwards under the action of gravity, the liquid will gather along the bottom wall of the inner tank to the position of the evaporation plate, which is conducive to evaporating the liquid to a greater extent.

[0026] In some embodiments, a steam oven is provided, further comprising a controller, the steam generator is electrically connected to the controller, and the evaporation plate is electrically connected to the controller;

[0027] The controller configuration is:

[0028] After the steam generator finishes working, the water outlet is controlled to be connected with the first opening.

[0029] This is conducive to improving the degree of automation and convenience.

[0030] In some embodiments, a steam oven is provided, wherein the controller is configured as follows:

[0031] Receive the steam mode operating time;

[0032] Determining whether the running time is not greater than a second preset time;

[0033] If yes, the steam generator is controlled to start working;

[0034] The steam generator stops working after the running time;

[0035] If not, the steam generator is controlled to start working;

[0036] The steam generator stops working after working for the first period of time;

[0037] The control water outlet is communicated with the first opening;

[0038] The evaporation disk is controlled to start working, and the evaporation disk stops working after working for a second time period; wherein the sum of the first time period and the second time period is equal to the operating time.

[0039] In this way, when the cooking time is short, the steam condensation water generated is less and does not affect the user's use, and the cooking needs can be met by using the steam generator. When the cooking time is long, the steam generator is used to generate steam to steam the food at the beginning. At the end of the steaming, the evaporation plate uses the residual water in the inner pot to steam the food, which can reduce the residual water in the inner pot.

[0040] In some embodiments, a steam oven is provided, wherein the ratio of the first time period to the second time period is a first ratio, the ratio of the rated power of the steam generator to the rated power of the evaporation plate is a second ratio, and the first ratio is 0.8-1.2 times the second ratio.

[0041] When the first ratio is less than 0.8 times of the second ratio, the first time period is shorter, the steam generator runs for a shorter time, the condensed water in the inner tank is less, and the evaporation plate requires more water from the water tank.

[0042] When the first ratio is 1.2 times greater than the second ratio, the first time period is longer, the steam generator runs for a longer time, there is more condensed water in the inner tank, and the condensed water is easy to remain after the evaporating disk works.

[0043] In some embodiments, a steam oven is provided, further comprising a water tank, the water tank being located above the steam generator;

[0044] The inner cavity of the water tank is connected to the water outlet through the inner cavity of the second pipe. A second control valve is arranged on the second pipe. The second control valve is configured to control the connection or disconnection between the water outlet and the water tank.

[0045] In this way, the liquid in the water tank can enter the steam generation under the action of gravity, thus eliminating the need for a water pump, which is beneficial to reducing noise and improving energy efficiency.

[0046] In some embodiments, a steam oven is provided, wherein the water tank comprises:

[0047] a housing connected to the shell;

[0048] The water box is slidably connected to the outer shell, and the water box is constructed as follows:

[0049] water-holding chamber;

[0050] A water inlet is connected to the water storage cavity.

[0051] A water outlet, the water outlet is connected to the water storage cavity, and the water outlet is connected to the second pipeline;

[0052] From a direction away from the water outlet to a direction close to the water outlet, the height of the inner bottom wall of the water holding cavity decreases.

[0053] In this way, under the action of gravity, the water in the water chamber can be drained.

[0054] In some embodiments, a steam oven is provided, wherein the water outlet is located at one end of the water box along the extension direction;

[0055] At least two baffles are arranged in the water storage cavity, and the at least two baffles are arranged at intervals along the extension direction of the water box. Each baffle is structured with a flow opening, and at least two flow openings are staggered.

[0056] In this way, when the user fills water into the water box, water can be poured into an area of ​​the baffle away from the water outlet, and the water flows slowly toward the water outlet through the flow port after being blocked by the baffle, thereby effectively avoiding the water filling speed being too fast, the water flow forming a surge in the water box, and the water splashing out of the water box.

[0057] In some embodiments, a steam oven is provided, further comprising a sealing structure, the sealing structure being located in the water storage cavity, close to the water outlet, and movably connected to the water box;

[0058] The outer shell is constructed with a communication structure, and the inner cavity of the communication structure is communicated with the water outlet;

[0059] When the communication structure is inserted into the water outlet, the communication structure pushes the blocking structure to move relative to the water box, a distance is provided between the blocking structure and the water outlet, and the water storage cavity is connected with the inner cavity of the communication structure;

[0060] When the connecting structure is separated from the water outlet, the sealing structure moves relative to the water box, and the sealing structure closes the water outlet.

[0061] In this way, the water outlet can be closed by providing a blocking structure, thereby effectively preventing the liquid in the water box from flowing out of the water outlet when the water box slides outward or inward.

[0062] In some embodiments, a steam oven is provided, further comprising:

[0063] An air duct assembly, the air duct assembly is located in the accommodating cavity;

[0064] The third pipe, the first opening is connected to the air duct cavity of the air duct assembly through the inner cavity of the third pipe, and a third control valve is arranged on the third pipe, and the third control valve is configured to control whether the first opening is connected to the air duct cavity of the air duct assembly or not.

[0065] In this way, when the pressure in the cooking chamber is too high, the inner pot is depressurized through the third pipe, thereby effectively avoiding vibration or whistling of the door when opening the door. BRIEF DESCRIPTION OF THE DRAWINGS

[0089] As described in the background art, the return pump makes a lot of noise when in operation. Moreover, the steam generated by the steam generator enters the inner tank and is pre-cooled and condensed into condensed water on the inner wall of the inner tank.

[0090] Based on the principle that liquid will flow to a lower place under the action of gravity, the present invention sets the water inlet of the steam generator above the first opening of the inner tank. When the water inlet is connected to the first opening, the residual liquid in the steam generator will flow into the inner tank under the action of gravity. In other words, the present invention directly discharges the residual water in the steam generator into the inner tank by eliminating the return water pump. Since steam forms water when it is cooled, and water can form steam by heating, an evaporation plate is set, and the evaporation plate uses the condensed water and residual water in the inner tank to heat and form steam, thereby effectively solving the technical problems of high noise during the operation of the return water pump and high condensed water in the inner tank, and achieving the purpose of low noise and low condensed water in the inner tank.

[0103] It should be noted that, in order to illustrate the internal structure of the steam oven, part of the shell 110 of the steam oven is removed in the figure.

[0104] In some embodiments, the cabinet 100 includes an inner container 120. The inner container 120 is configured to provide a cooking environment.

[0105] The inner liner 120 is located in the housing 110. Specifically, the inner liner 120 is located in the accommodating cavity.

[0106] In some embodiments, the inner pot 120 is configured with a cooking cavity.

[0107] In some embodiments, the inner pot 120 is configured with a first opening 121 communicating with the cooking cavity. Steam in the inner pot 120 can flow to the outside of the inner pot 120 through the first opening 121. Alternatively, external liquid can flow into the inner pot 120 through the first opening 121.

[0108] In some embodiments, the inner pot 120 is configured with a first steam port 122 communicating with the cooking cavity. External steam can flow into the inner pot 120 through the first steam port 122 .

[0109] See also Figure 1 As shown, in some embodiments, the steam oven includes a door body 300 .

[0110] The door body 300 is rotatably connected to the cabinet 100, and the door body 300 rotates relative to the cabinet 100 to open or close the cooking cavity.

[0111] Specifically, the door body 300 may be rotatably connected to the box body 100 at a position close to the bottom.

[0112] In some embodiments, the door body 300 includes an operating handle, which is disposed at the front side of the door body 300. In this way, it is convenient for the user to open and close the door body 300.

[0118] See also Figures 3 to 5 As shown, in some embodiments, the steam oven includes a steam system 200. The steam system 200 is configured to generate steam and deliver the steam to the cooking cavity to heat food.

[0119] In some embodiments, the steam system 200 includes a steam generator 220. The steam generator 220 is configured to heat liquid into steam.

[0120] It should be noted that the steam generator 220 may be a boiler-type steam generator, an electrically heated steam generator, or an electrode-type steam generator, etc., which is not specifically limited in this embodiment.

[0121] Figure 6 This is a schematic diagram of the structure of the steam oven provided in an embodiment of the present application with the door body removed.

[0122] See also Figure 6 As shown, in some embodiments, the steam system 200 includes an evaporation plate 210. After the liquid in the liner 120 contacts the evaporation plate 210, the liquid is heated by the evaporation plate 210 to become steam.

[0123] In some embodiments, the evaporation plate 210 is located near the bottom of the inner pot 120 and is at least partially located in the cooking cavity.

[0124] In some embodiments, the evaporation plate 210 is embedded in the inner bottom of the cooking cavity.

[0125] It is understandable that based on the principle that steam forms water when it cools and water flows downward under the action of gravity, the condensed water in the inner tank 120 will gather at the bottom of the inner tank 120, and the evaporation plate 210 is located at the bottom, which is conducive to evaporating the condensed water to a greater extent.

[0126] The evaporation plate 210 may be an evaporation plate commonly used in the related art, and will not be described in detail in the embodiment of the present application.

[0127] See also Figure 3 and Figure 5 As shown, in some embodiments, the steam system 200 includes a water tank 230 configured to hold liquid.

[0134] Figure 7 A schematic diagram of the structure of a steam generator in a steam oven provided in an embodiment of the present application, Figure 8 Another structural schematic diagram of the steam generator in the steam oven provided in an embodiment of the present application.

[0135] See also Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, the steam generator 220 includes a body 221. The body 221 is configured to heat liquid into steam.

[0136] Specifically, the body 221 may include a coil, and the coil is configured to flow liquid and steam.

[0137] The body 221 may include a second heating element. The second heating element is disposed on the outer wall of the coil to heat the coil.

[0138] The second heating element may be a heating wire or a heating plate.

[0139] In some embodiments, the body 221 includes a container configured to flow liquid and vapor.

[0140] The body 221 includes a heating electrode. The heating electrode is located in the container and is configured to heat the liquid in the container.

[0141] In some embodiments, the steam generator 220 includes a steam pipe 222 .

[0142] It is understandable that by providing the steam pipe 222, it is convenient for the steam generator 220 to communicate with the inner pot 120 through the pipe. The steam generated by the steam generator 220 enters the inner pot 120 through the pipe to heat the food.

[0143] The steam pipe 222 is in communication with the body 221. The steam in the body 221 flows to the outside of the steam generator 220 through the steam pipe.

[0144] In some embodiments, the steam pipe 222 is configured with a second steam port 2221, and the second steam port 2221 is in communication with the first steam port 122. The steam in the body 221 flows into the cooking cavity through the steam pipe 222, the second steam port 2221, and the first steam port 122.

[0145] In some embodiments, the steam generator 220 includes a water pipe 223 .

[0146] It is understandable that the water pipe 223 is provided to facilitate communication with the inner container 120 through a pipeline, and to facilitate communication with the water tank 230 through a pipeline.

[0147] The water pipe 223 is in communication with the body 221 . The liquid in the body 221 flows to the outside of the steam generator 220 through the water pipe 223 . The liquid outside flows to the body 221 through the water pipe 223 .

[0148] In some embodiments, the water pipe 223 is configured with a water inlet 2231 .

[0149] The water inlet 2231 is located above the first opening 121. When the water inlet 2231 is connected to the first opening 121, the liquid in the body 221 flows into the cooking cavity through the water pipe 223, the water inlet 2231 and the first opening 121.

[0150] It can be understood that based on the principle that liquid will flow downward under the action of gravity, the water outlet 2231 is located above the first opening 121. When the water outlet 2231 is connected to the first opening 121, the residual liquid in the main body 221 will flow into the cooking cavity through the water pipe 223, the water outlet 2231 and the first opening 121 in sequence under the action of gravity.

[0151] Moreover, based on the principle that water flows downward under the action of gravity, the residual liquid will gather at the bottom of the inner tank 120, and the evaporation plate 210 is located at the bottom, which is conducive to evaporating the residual liquid to a greater extent.

[0152] See also Figure 7 and Figure 8As shown, when the body 221 includes a coil, in order to increase the overall length of the coil and increase the area of ​​heat transfer between the liquid and the second heating element, the water pipe 223 and the steam pipe 222 are arranged on opposite sides of the body 221.

[0153] See also Figure 7 As shown, the water pipe 223 and the steam pipe 222 are arranged on opposite sides of the body 221 along the height direction (the direction shown by the Y axis).

[0154] See also Figure 8 As shown, the water pipe 223 and the steam pipe 222 are arranged on opposite sides of the body 221 along the width direction (the direction shown by the X-axis).

[0155] In some embodiments, the water pipe 223 may be a straight pipe to facilitate the flow of liquid.

[0156] In some embodiments, the water inlet 2231 is located at a side of the water pipe 223 that is away from the body 221 along the extension direction. The water inlet 2231 is connected to the first opening 121 through the first pipe 240 .

[0157] It is understandable that the first pipe 240 can be sleeved on the outer wall of the water pipe 223 , or the first pipe 240 can be inserted into the water outlet 2231 .

[0158] In some embodiments, the extension direction of the water pipe 223 is at an angle to the ground. The body 221 is located above the first pipe 240. In this way, under the action of gravity, the residual liquid in the body 221 can be drained to a greater extent.

[0159] It should be noted that the straight line where line a is located in the figure represents the ground. When the water pipe 223 is a round pipe, the extension direction of the water pipe 223 can be the axial direction of the water pipe 223. When the water pipe 223 is a square pipe, the extension direction of the water pipe 223 can be the length direction of the water pipe 223.

[0160] In some embodiments, see Figure 7 As shown, the water pipe 223 can be located at the bottom of the body 221.

[0161] In some embodiments, the angle between the extension direction of the water pipe 223 and the ground is greater than 0 degrees.

[0162] In some embodiments, the angle between the extension direction of the water pipe 223 and the ground is 90 degrees. In this way, the space around the water pipe 223 is large, which is convenient for connecting the first pipeline 240 with the water pipe 223.

[0163] In some embodiments, see Figure 8 As shown, the water pipe 223 may be located at one side of the body 221 along the width direction and close to the bottom of the body 221 .

[0164] It is understandable that in the related art, the water pipe 223 can be located on one side of the body 221 along the width direction. There are more types and applications of the steam generator 220. On this basis, the water pipe 223 is modified with minor changes, which is conducive to lower costs.

[0165] See also Figure 8 As shown, in some embodiments, 1 degree < angle b < 5 degrees.

[0166] In some embodiments, the angle b is 1 to 5 degrees.

[0167] The angle b may be 2 degrees, or the angle b may be 4 degrees.

[0168] It can be understood that when the angle b is less than 1 degree, the inclination angle is small, which is not conducive to the outflow of residual liquid in the body 221.

[0169] When the angle b is greater than 5 degrees, the inclination angle is relatively large. When improvements are made on the basis of the zero angle in the steam generator 220 in the related art, the changes are relatively large, and the mold needs to be reprocessed, which is costly.

[0170] Also, see Figure 3 As shown, in some embodiments, the water pipe 223 connects the first pipe 240 and the second pipe 250 through a tee pipe. When the inclination angle of the water pipe 223 is greater than 5 degrees, the first pipe 240 and the second pipe 250 occupy a large space along the direction shown by the Y axis in the figure without changing the tee pipe structure. And it is not conducive to the liquid in the second pipe 250 to flow into the steam generator 220 under the action of gravity.

[0171] In some embodiments, a first control valve 260 is disposed on the first pipe 240. The first control valve 260 is configured to control the connection or disconnection between the water port 2231 and the first opening 121. In this way, it is convenient to control the connection or disconnection between the water port 2231 and the first opening 121.

[0172] The first control valve 260 may be a solenoid valve.

[0173] See also Figure 6 As shown, in some embodiments, the evaporation tray 210 is located in the middle area of ​​the bottom wall of the inner container 120 , and the height of the bottom wall of the inner container 120 increases along the direction from the evaporation tray 210 to the side wall of the inner container 120 .

[0174] Based on the principle that water will flow downwards under the action of gravity, the liquid gathers along the bottom wall of the inner tank 120 to the position of the evaporation plate 210, which is conducive to evaporating the liquid to a greater extent.

[0175] It is understandable that the bottom wall of the inner container 120 gradually increases in height from the evaporation tray 210 to the side wall of the inner container 120. Alternatively, the bottom wall of the inner container 120 increases in height in a step-like manner from the evaporation tray 210 to the side wall of the inner container 120.

[0176] In some embodiments, along the radial direction of the evaporation tray 210 , the height of the bottom wall of the liner 120 decreases from the side wall of the liner 120 to the edge of the evaporation tray 210 .

[0177] In some embodiments, the inner cavity of the water tank 230 is connected to the water inlet 2231 through the second pipe 250 .

[0178] In some embodiments, the water tank 230 is located above the steam generator 220. In this way, based on the principle of communicating vessels, the liquid in the water tank 230 can flow into the steam generator 220 under the action of gravity, without the need to set up a water inlet pump, which is conducive to reducing noise and energy consumption.

[0179] In some embodiments, a second control valve 270 is provided on the second pipe 250, and the second control valve 270 is configured to control the connection or disconnection between the water inlet 2231 and the water tank 230. In this way, when there is no need to supply water to the steam generator 220, the water inlet 2231 can be disconnected from the inner cavity of the water tank 230, thereby effectively preventing the liquid from entering the steam generator 220 under the action of gravity.

[0180] In some embodiments, a water inlet pump is further included, and the water inlet pump is connected to the second pipe 250. The water inlet pump is used to transport the liquid in the water tank 230 to the steam generator 220 through the second pipe 250.

[0181] Fig. 9 This is a schematic diagram of the structure of a water tank in a steam oven provided in an embodiment of the present application. Fig.10 An exploded view of a water tank in a steam oven provided in an embodiment of the present application.

[0182] See also Fig. 9 and Fig.10 As shown, in some embodiments, the water tank 230 includes a housing 231 , wherein the housing 231 is connected to the housing 110 .

[0183] Specifically, the housing 231 is connected to the housing 110, for example, by means of screws or buckles.

[0184] In some embodiments, the housing 231 includes a first base 2311 , and the first base 2311 is connected to the housing 110 .

[0185] In some embodiments, the housing 231 includes a first cover plate 2312 , wherein the first cover plate 2312 is disposed on the top of the first base 2311 .

[0186] The first cover plate 2312 and the first base 2311 may be detachably connected, for example, by means of screws or buckles.

[0187] In some embodiments, the water tank 230 includes a water box 232. The water box 232 is slidably connected to the housing 231.

[0188] Specifically, the water box 232 can slide relative to the housing 231 so as to be located inside the housing 231 or detached from the housing 231, thereby facilitating water addition and cleaning by the user.

[0189] Fig.11 This is a schematic diagram of the structure of the water box in the steam oven provided in an embodiment of the present application. Fig.12 This is a schematic structural diagram of another angle of the water box in the steam oven provided in an embodiment of the present application.

[0190] See also Fig.11 As shown, in some embodiments, the water box 232 is configured with: a water holding chamber 2322. The water holding chamber 2322 is configured to hold liquid.

[0191] In some embodiments, the water box 232 is configured with a water inlet. The water inlet is in communication with the water holding chamber 2322. The water inlet is configured to add liquid to the water holding chamber 2322 through the water inlet.

[0192] In some embodiments, the water box 232 includes a second base that is slidably connected to the housing 231 .

[0193] In some embodiments, the top of the second base is opened, and the opening is a water inlet.

[0194] In some embodiments, the water box 232 includes a second cover plate, wherein the second cover plate is disposed on the top of the second base, and a water inlet is configured on the second cover plate.

[0195] The second cover plate is detachably connected to the second base, so that it is convenient for the user to clean the inside of the second cover plate and the second base.

[0196] In some embodiments, the water box 232 is configured with a water outlet 2321. The water outlet 2321 is in communication with the water storage chamber 2322. The water outlet 2321 is in communication with the second pipe 250. The liquid in the water storage chamber 2322 enters the inner cavity of the steam generator 220 through the water outlet 2321 and the inner cavity of the second pipe 250.

[0197] See also Fig.11 and Fig.12 As shown, in some embodiments, the height of the inner bottom wall of the water holding chamber 2322 decreases from the direction away from the water outlet 2321 to the direction close to the water outlet 2321. In this way, the water in the water holding chamber 2322 can be drained.

[0198] In some embodiments, the water inlet is close to one end of the water box 232 along the extension direction, and the water outlet 2321 is close to the other end of the water box 232 along the extension direction.

[0199] In some embodiments, at least two baffles 233 are disposed in the water chamber 2322 , and the at least two baffles 233 are spaced apart along the extension direction of the water box 232 to divide the water chamber 2322 into different areas.

[0200] The baffle 233 is configured with flow openings 2331, and a line connecting at least two flow openings 2331 forms an angle with the extension direction of the water box 232. That is, at least two flow openings 2331 are staggered.

[0201] It is understandable that the flow path of the liquid can be changed by providing the baffle 233 and the staggered flow openings 2331. In this way, when a user fills water into the water box 232, water can be poured into a region of a baffle 233 away from the water outlet 2321, and the water flows slowly toward the water outlet 2321 through the flow openings 2331 after being blocked by the baffle 233, thereby effectively preventing the water from being filled too quickly, causing the water to form a surge in the water box 232 and splashing out of the water box 232.

[0202] See also Fig.12 As shown, an operating portion 234 is provided at the bottom of the water box 232 on the side away from the water outlet 2321. The operating portion 234 facilitates the user to pull the water box 232 to slide relative to the housing 231.

[0203] The operating portion 234 may be a recessed handle or a groove.

[0204] Fig.13 This is a schematic diagram of the structure of the water box and the sealing structure in the steam oven provided in the embodiment of the present application. Fig.14 for Fig.13 A partial enlarged view of point C in the middle. Fig.15 This is a schematic diagram of the structure of the shell of the steam oven provided in the embodiment of the present application. Fig.16 for Fig.15 A partial enlarged view of point D in the middle. Fig.17 for Fig.11 A partial enlarged view of point E in the middle.

[0205] See also Figures 13 to 17 As shown, in some embodiments, the water tank 230 includes a blocking structure 235 .

[0206] The sealing structure 235 is located in the water storage cavity 2322 , and is close to the water outlet 2321 . The sealing structure 235 is movably connected to the water box 232 .

[0207] The outer shell 231 is configured with a communication structure 2313 , and the inner cavity of the communication structure 2313 is communicated with the water inlet 2231 .

[0208] When the connecting structure 2313 is inserted into the water outlet 2321 , the connecting structure 2313 pushes the blocking structure 235 to move relative to the water box 232 . There is a distance between the blocking structure 235 and the water outlet 2321 , and the water chamber 2322 is connected to the inner chamber of the connecting structure 2313 .

[0209] When the connecting structure 2313 is separated from the water outlet 2321 , the blocking structure 235 moves relative to the water box 232 , and the blocking structure 235 closes the water outlet 2321 .

[0210] In some embodiments, the blocking structure 235 is rotatably connected to the water box 232 .

[0211] Specifically, the blocking structure 235 includes an elastic member and a sealing plate, and the sealing plate is rotatably connected to the water box 232. The elastic member is connected to the sealing plate and to the water box 232.

[0212] When the connecting structure 2313 is inserted into the water outlet 2321 , the connecting structure 2313 contacts the sealing plate and pushes the sealing plate to rotate relative to the water box 232 . There is a distance between the sealing plate and the water outlet 2321 , and the water chamber 2322 is connected to the connecting structure 2313 .

[0213] When the connecting structure 2313 is separated from the water outlet 2321, for example, when the water box 232 is pulled out to add water, the connecting structure 2313 is separated from the sealing plate, and the sealing plate rotates relative to the water box 232 under the action of the elastic member, and the sealing plate covers the water outlet 2321, thereby closing the water outlet 2321.

[0214] In some embodiments, the blocking structure 235 is slidably connected to the water box 232 .

[0215] In some embodiments, the blocking structure 235 includes a fixing seat 2351 .

[0216] The fixing seat 2351 is connected to the inner wall of the water box 232 .

[0217] The fixing seat 2351 is opened toward one side of the water outlet 2321 .

[0218] In some embodiments, the blocking structure 235 includes a push rod 2352 .

[0219] The push rod 2352 is slidably connected to the fixing seat 2351. The push rod 2352 is located on a side of the fixing seat 2351 facing the water outlet 2321.

[0220] The push rod 2352 slides relative to the fixing seat 2351 to move closer to or away from the water outlet 2321 .

[0221] The push rod 2352 can be inserted into the water outlet 2321 to block the water outlet 2321 .

[0222] In some embodiments, the retaining structure 235 includes a sealing plate 2353 .

[0223] The sealing plate 2353 is connected to the push rod 2352 , and the sealing plate 2353 is located on a side of the push rod 2352 away from the fixing seat 2351 .

[0224] The sealing plate 2353 may cover the water outlet 2321 , thereby blocking the water outlet 2321 .

[0225] The orthographic projection of the push rod 2352 toward the side wall where the water outlet 2321 is located is located within the orthographic projection of the sealing plate 2353 toward the side wall where the water outlet 2321 is located, that is, the end surface area of ​​the push rod 2352 is smaller than the end surface area of ​​the sealing plate 2353. In this way, the contact area between the sealing plate 2353 and the side wall is larger, which is conducive to improving the sealing effect.

[0226] In some embodiments, the blocking structure 235 includes an elastic member.

[0227] One end of the elastic member along the elastic force direction is connected to the fixing seat 2351 , and the other end is connected to the push rod 2352 .

[0228] The elastic member is arranged in the fixing seat 2351 , so that the elastic member can be separated from the liquid, thereby increasing the service life of the elastic member and effectively preventing the elastic member from contaminating the liquid.

[0229] Alternatively, one end of the elastic member along the elastic force direction is connected to the fixing seat 2351 , and the other end is connected to the sealing plate 2353 .

[0230] Exemplarily, the elastic member may be a spring or elastic rubber.

[0231] When the connecting structure 2313 is inserted into the water outlet 2321 , the connecting structure 2313 contacts the sealing plate 2353 and pushes the sealing plate 2353 to move relative to the water box 232 . There is a distance between the sealing plate 2353 and the water outlet 2321 , and the water chamber 2322 is connected to the inner chamber of the connecting structure 2313 .

[0232] When the connecting structure 2313 is separated from the water outlet 2321 , for example, when the water box 232 is pulled out to add water, the connecting structure 2313 is separated from the sealing plate 2353 , and the sealing plate 2353 moves relative to the water box 232 under the action of the elastic member, and the sealing plate 2353 covers the water outlet 2321 .

[0233] See also Fig.17 As shown, the inner wall of the water box 232 is configured with a connection structure 2323. The fixing seat 2351 is connected to the connection structure 2323.

[0234] The connection structure 2323 may surround a portion of the side wall of the fixing seat 2351 .

[0235] Specifically, the fixing seat 2351 can be engaged with the connecting structure 2323. In this way, the blocking structure 235 can be easily disassembled and installed.

[0236] See also Fig.17 As shown, the inner wall of the water box 232 is constructed with a limiting structure 2324. The limiting structure 2324 is used to limit the moving direction of the sealing plate 2353.

[0237] The limiting structure 2324 includes a first limiting portion and a second limiting portion, and the first limiting portion and the second limiting portion are spaced apart and arranged opposite to each other. The first limiting portion and the second limiting portion are located at two opposite sides of the sealing plate 2353 .

[0238] See also Fig.15 and Fig.16 As shown, in some embodiments, the communication structure 2313 is disposed on the inner wall of the housing 231 and is opposite to the side of the water box 232 having the water outlet 2321 .

[0239] In some embodiments, the communication structure 2313 includes a communication protrusion.

[0240] The connecting protrusion can be cylindrical or rectangular. The connecting structure 2313 is hollow.

[0241] In some embodiments, the extending direction of the connecting structure 2313 is parallel to the axial direction of the water outlet 2321. Along the axial direction of the connecting structure 2313, the cross-sectional size of the connecting structure 2313 increases from the end close to the water box 232 to the end far from the water box 232. In this way, the connecting structure 2313 is inserted into the water outlet 2321 to push the blocking structure 235.

[0242] For example, along the axial direction of the connecting structure 2313 , from an end close to the water box 232 to an end far away from the water box 232 , the cross-sectional size of the connecting structure 2313 gradually increases.

[0243] In some embodiments, the outer wall of the communication structure 2313 has a taper.

[0244] It is understandable that during high-temperature steaming and high-temperature baking, the pressure in the cooking cavity will increase sharply due to the strong movement of molecules in the cooking cavity due to the good sealing of the cooking cavity of the inner pot 120. During the process of opening and closing the door, the door body is prone to vibration and whistling due to air vortex and other reasons.

[0245] In order to solve the above technical problem, a third pipe 290 is added between the inner tank 120 and the air duct assembly 280 .

[0246] See also Figure 5 As shown, in some embodiments, the steam oven further includes a third pipe 290 .

[0247] The first opening 121 is connected to the air duct cavity of the air duct assembly 280 through the inner cavity of the third pipe 290 .

[0248] That is to say, the cooking cavity of the inner pot 120 and the air duct cavity are connected through the inner cavity of the third pipe 290. When the pressure in the cooking cavity is too high, the inner pot 120 is depressurized through the third pipe 290, thereby effectively avoiding vibration or howling of the door when opening the door.

[0249] In some embodiments, a third control valve 2100 is disposed on the third pipeline 290 , and the third control valve 2100 is configured to control the communication or non-communication between the first opening 121 and the air duct cavity of the air duct assembly 280 .

[0250] Specifically, the third control valve 2100 may be a pressure valve.

[0251] It can be understood that the third pipe 290 is provided with a pressure valve. When the pressure in the inner tank 120 exceeds the pressure value at which vibration and howling may occur, the pressure valve opens, and the hot air in the inner tank 120 is discharged into the air duct assembly 280 for pressure relief until the pressure valve value is lower than the set value and the pressure valve closes.

[0252] Alternatively, in some embodiments, the third control valve 2100 may be a solenoid valve. The pressure in the inner cavity is detected by a pressure sensor.

[0253] In some embodiments, the control system includes a control panel, which is configured to receive user instructions, and the steam oven operates according to the user instructions.

[0254] The control panel is arranged on the front side of the box body 100. In this way, it is convenient for the user to operate the control panel.

[0255] Wherein, the control panel can be located above the door body.

[0256] In some embodiments, the control system includes a controller. The controller may be located in the receiving cavity.

[0257] In some embodiments, the control panel is electrically connected to the controller.

[0258] In some embodiments, the steam generator 220 is electrically connected to the controller, and the evaporation pan 210 is electrically connected to the controller.

[0259] In some embodiments, the controller is configured to control the water inlet 2231 to communicate with the first opening 121 after the steam generator 220 finishes working.

[0260] After the steam generator 220 finishes working, the water port 2231 is controlled to communicate with the first opening 121, so as to discharge the residual water into the cooking cavity.

[0261] Specifically, the first control valve 260 is electrically connected to the controller, and the controller can control the communication or disconnection between the water port 2231 and the first opening 121 through the first control valve 260 .

[0262] In some embodiments, the second control valve 270 is electrically connected to the controller, and the controller can control the connection or disconnection between the water inlet 2231 and the water storage chamber 2322 of the water tank 230 through the second control valve 270 .

[0263] In some embodiments, the third control valve 2100 is electrically connected to the controller, and the controller can control the connection or disconnection between the air duct cavity of the air duct assembly 280 and the first opening 121 through the third control valve 2100 .

[0264] In some embodiments, the third control valve 2100 is electrically connected to the controller, and the pressure sensor is electrically connected to the controller. The controller can control the connection or disconnection between the air duct cavity of the air duct assembly 280 and the first opening 121 through the third control valve 2100 and the pressure sensor.

[0265] In some embodiments, the controller is configured to:

[0266] After the water inlet 2231 is connected to the first opening 121 for a first preset time, the evaporation plate 210 is controlled to operate.

[0267] This helps to drain the residual water in the steam generator 220 and prevent the evaporation pan 210 from drying out.

[0268] Exemplarily, the first preset time may be 6-20 seconds, for example, 10 seconds or 15 seconds.

[0269] In some embodiments, the controller is configured to:

[0270] When the water inlet 2231 is connected to the first opening 121 , the evaporation plate 210 is controlled to operate.

[0271] In some embodiments, the controller is configured to:

[0272] After the water port 2231 is connected to the first opening 121 for a first preset time, the water port 2231 is controlled to be disconnected from the first opening 121 .

[0273] In some embodiments, the controller is configured to:

[0274] Receives the operating time of the steam mode.

[0275] Specifically, the running time may be a time set by a user or a time requirement in an electronic recipe.

[0276] It is determined whether the running time is not greater than a second preset time.

[0277] It should be noted that the second preset time can be set according to the test result. Exemplarily, the second preset time can be 0 to 10 minutes, such as 5 minutes or 8 minutes.

[0278] If yes, the steam generator 220 is controlled to start working. The steam generator 220 stops working after the working time.

[0279] It is understandable that when the cooking time is short, the steam condensate generated is less and does not affect user use, and the cooking needs can be met by using the steam generator 220.

[0280] Specifically, the controller can control the water inlet 2231 to communicate with the water storage chamber 2322 of the water tank 230 through the second control valve 270, so that the water in the water tank 230 enters the steam generator.

[0281] If not, the steam generator 220 is controlled to start working. The steam generator 220 stops working after working for a first period of time.

[0282] The control water port 2231 is communicated with the first opening 121 .

[0283] The evaporation disk 210 is controlled to start working, and the evaporation disk 210 stops working after working for a second period of time.

[0284] The sum of the first time period and the second time period is equal to the running time.

[0285] In this way, the steam generator 220 and the evaporation plate 210 take turns to work, that is, at the beginning of work, the steam generator 220 is used to generate steam to steam food, and at the end of steaming food, the evaporation plate 210 works to use the residual water in the inner pot 120 to steam the food, which can reduce the amount of residual water in the inner pot 120.

[0286] It should be noted that when the evaporation pan 210 is dry-burned during cooking, that is, when it is unable to generate steam, the water tank 230 provides liquid to the evaporation pan 210 .

[0287] Specifically, the first control valve 260 and the second control valve 270 are opened at the same time.

[0288] For example, the first control valve 260 and the second control valve 270 are opened simultaneously for 5 seconds to replenish water to the evaporation disk 210, and after 5 seconds, the second control valve 270 is closed first, and after an interval of 2 seconds, the first control valve 260 is closed. The opening and closing time needs to be determined according to actual conditions.

[0289] In some embodiments, the ratio of the first time period to the second time period is a first ratio. The ratio of the rated power of the steam generator 220 to the rated power of the evaporation pan 210 is a second ratio. The first ratio is 0.8-1.2 times the second ratio.

[0290] In some embodiments, the ratio of the first time period to the second time period is 1 times the rated power of the steam generator 220 and the rated power of the evaporation pan 210 .

[0291] In some embodiments, the ratio of the first time period to the second time period is 0.9 times the rated power of the steam generator 220 and the rated power of the evaporation pan 210 .

[0292] Exemplarily, the steam generator 220 is selected to have a relatively large power, such as 1500W. The evaporation tray 210 is selected to have a power of 800W. During long cooking, the steam generator 220 generates excess condensed water in the inner pot 120, and the working time of the steam generator 220 and the evaporation tray 210 can be allocated in a ratio of 2:1. Thus, the evaporation tray 210 can be effectively used to evaporate the water in the inner pot 120. Exemplarily, the steam generator 220 runs for 20 minutes, and the evaporation tray 210 runs for 10 minutes.

[0293] It is understandable that when the first ratio is less than 0.8 times the second ratio, the first time period is shorter, the steam generator 220 runs for a shorter time, the condensed water in the inner tank 120 is less, and the evaporation plate 210 requires more water from the water tank 230.

[0294] When the first ratio is 1.2 times greater than the second ratio, the first time period is longer, the steam generator 220 runs for a longer time, there is more condensed water in the inner tank 120, and the condensed water is easy to remain after the evaporation plate 210 works.
