[0069] As described in the background technology, in the related art, the steam oven only takes in water, and the water discharged into the steam generator by the water pump will not be pumped back after the work is completed, resulting in water always being in the steam generator. If it is not used for a long time, the residual water will easily deteriorate and affect health.

[0070] Moreover, when descaling, it is necessary to add citric acid descaling agent into the water tank, and then pump it into the steam generator through a water pump, and remove the scale in the steam generator by heating and soaking. However, in the related art, since there is no water return device, after descaling is completed, the descaling agent in the steam generator cannot be withdrawn and collected, and can only be diluted and flushed out into the inner tank by injecting clean water again. The water capacity that the inner tank can hold is limited, and the steam generator cannot be flushed multiple times. Multiple water injections will cause the inner tank to overflow onto the table, and the user needs to manually wipe the citric acid descaling agent discharged into the inner tank, which is less convenient. For smaller coil steam generators, due to their thin diameter, they are sensitive to scale and need to be descaled frequently, otherwise the steam generator is prone to clogging. Frequent descaling undoubtedly increases the burden on users.

[0071] In order to solve the above-mentioned technical problems, the present application provides a steam oven. When in operation, a water tank is provided to hold liquid, and the liquid is transported to the steam generator through a water inlet pump. The steam generated by the steam generator enters the inner tank through the air inlet pipe. A drain pump is provided to transport the residual liquid in the steam generator to the water tank through the drain pump. When descaling, a prepared descaling agent is placed in the water tank, and the descaling mode is started. The descaling agent is pumped into the steam generator by the water inlet pump. The descaling agent fills the entire steam generator pipeline for soaking and descaling. After descaling is completed, the drain pump is started to pump the descaling agent back into the water tank for collection, making it convenient for the user to clean. Among them, at least a part of the air inlet pipe is located above the steam generator's air outlet. In this way, the descaling agent can be soaked into the steam generator's air outlet, effectively removing scale from the steam generator's air outlet.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0079] Figure 1 This is a schematic diagram of the structure of the steam oven provided in the embodiment of the present application. Figure 2 This is a schematic structural diagram of the steam oven provided in an embodiment of the present application from another angle.

[0080] An embodiment of the present application provides a steam oven, which may be a stand-alone steam oven or a built-in steam oven.

[0081] See also Figure 1 and Figure 2 As shown, the steam oven provided in the embodiment of the present application includes: a shell 100.

[0082] The housing 100 can provide both aesthetics and protection.

[0083] The housing 100 is configured with an inner cavity, which is used to provide installation space for other components of the steam oven.

[0084] In some embodiments, the steam oven includes: an inner container 200 .

[0085] The inner liner 200 is located in the shell 100 , that is, the inner liner 200 is located in the inner cavity of the shell 100 .

[0086] The inner pot 200 is configured with a cooking cavity for placing food.

[0087] The front side of the cooking cavity is opened, and the user places the food into the cooking cavity through the opening.

[0088] It should be noted that the front side is the side of the steam oven facing the user.

[0089] In some embodiments, the steam oven includes: a door body 300 .

[0090] The door body 300 is rotatably connected to the housing 100 , and the door body 300 rotates relative to the housing 100 to open or close the opening of the cooking cavity.

[0091] In some embodiments, the steam oven includes: a control panel 400 .

[0092] The control panel 400 may be provided on the housing 100 , and the control panel 400 may be located above the door 300 .

[0093] Figure 3 This is a schematic diagram of the structure of the steam oven provided in an embodiment of the present application after removing part of the shell. Figure 4 for Figure 3 The main view, Figure 5 This is a schematic diagram of the water channel structure and inner pot structure of the steam oven provided in the embodiment of the present application. Figure 6 for Figure 5 A partial enlarged view of point D in the middle.

[0094] See also Figures 3 to 6 As shown, in some embodiments, the steam oven includes a water channel structure 500 .

[0095] The water channel structure 500 can be used to provide steam to the cooking cavity. The water channel structure 500 is located in the inner cavity of the housing 100 .

[0096] In some embodiments, the waterway structure 500 includes a water tank 510 .

[0097] The water tank 510 is located in the inner cavity. Specifically, the water tank 510 has a water storage cavity for storing liquid.

[0098] In some embodiments, the waterway structure 500 includes a water intake pump 520 .

[0099] The water inlet pump 520 is configured to transport the liquid in the water tank 510 to the steam generator 530 .

[0100] The water inlet pump 520 is located in the inner cavity, and the water inlet pump 520 is connected to the water tank 510 and the steam generator 530 .

[0101] Specifically, the water inlet pump 520 may be in communication with the water tank 510 through a pipeline, and the water inlet pump 520 may be in communication with the steam generator 530 through a pipeline.

[0102] In some embodiments, the water inlet pump 520 may be a diaphragm pump. Diaphragm pumps offer advantages such as precise flow control, low cost, and low noise. However, some diaphragm pumps lack a seal after power failure. When a water tank 510 is located above the diaphragm pump, water in the tank 510 continues to flow into the diaphragm pump under gravity, causing water to drip slowly from the pump's outlet.

[0103] To address the aforementioned technical issues, a check valve is typically added downstream of the diaphragm pump to stop water flow when the pump is not operating. However, the check valve's force must be matched to the pump's intended function. If the force is too low, water can still flow through without stopping the flow, while if the force is too high, the pump will not be able to open the check valve.

[0104] Based on this, in some embodiments, the water inlet pump 520 is a diaphragm pump with an integrated one-way valve. In this way, there is no need to separately set up a one-way valve, and there is no need to match the one-way valve with a suitable type.

[0105] In some embodiments, the waterway structure 500 includes a drain pump configured to transport liquid in the steam generator 530 to the water tank 510 .

[0106] The drain pump is located in the inner cavity and is in communication with the water tank 510 and the steam generator 530 .

[0107] Specifically, the drain pump may be in communication with the water tank 510 through a pipeline, and the drain pump may be in communication with the steam generator 530 through a pipeline.

[0108] In some embodiments, the steam generator 530 is configured with a water inlet 531 , and the drain pump and the water inlet pump 520 can be connected to the water inlet 531 of the steam generator 530 through a tee pipe.

[0109] In some embodiments, the drainage pump 540 may be a diaphragm pump, which has the advantages of precise flow control, low cost, and low noise.

[0110] In some embodiments, the drain pump 540 may be an electromagnetic pump. The water discharged by the drain pump 540 contains scale particles, and the electromagnetic pump is less likely to clog than a diaphragm pump.

[0111] In some embodiments, the waterway structure 500 includes a steam generator 530 .

[0112] The steam generator 530 is used to generate steam and deliver the steam to the cooking cavity.

[0113] The steam generator 530 is located in the inner cavity, the steam generator 530 is connected to the water inlet pump 520 , and the steam generator 530 is connected to the drainage pump 540 .

[0114] Figure 7 A schematic structural diagram of a steam generator in a steam oven provided in an embodiment of the present application.

[0115] See also Figure 7 As shown, the steam generator 530 is configured with an air outlet 532 .

[0116] In the related art, the steam generator 530 is a straight tube steam generator used in conjunction with a silicone rubber water vapor separator. However, the silicone rubber water vapor separator is relatively expensive, and the straight tube water vapor separator evaporates quickly, requiring frequent water replenishment, making it difficult to achieve uniform and stable steam output.

[0117] Based on this, in some embodiments, the steam generator 530 may be a coil-and-tube steam generator. The steam generator 530 may be a coil-and-tube steam generator with a relatively small volume.

[0118] It is understandable that the coil-type steam generator is small in size, does not require other components, and can achieve stable steam output by injecting water through a water pump with a stable flow rate.

[0119] In some embodiments, water can enter the steam generator 530 through the water inlet 531 of the steam generator 530, enter the inlet of the spiral water pipe, and then rise along the spiral water pipe. During this process, the heating pipe is energized to heat the water in the surrounding spiral water pipe. Before reaching the outlet of the spiral water pipe, the water is heated to a boil, generating steam. By the time it reaches the outlet 532 of the steam generator 530, it has completely turned into steam. The steam then flows through the air inlet pipe into the cooking chamber, completing the cooking process.

[0120] Specifically, by controlling the duty cycle of the water inlet pump 520 and cooperating with the heating pipe, the water in the spiral water pipe can reach a balance between water replenishment and evaporation, and the water level is stabilized at an appropriate position, which will not cause water spraying from the air outlet 532.

[0121] When the water level is too low and the steam generator 530 is dry-burning, the temperature sensor on the steam generator 530 will sense the temperature rise and notify you to add water to avoid dry-burning.

[0122] It should be noted that this embodiment only exemplarily provides a steam generator structure. In other embodiments, the spiral distribution of the water pipes and the distribution of the heating pipes may be different.

[0123] See also Figures 3 to 6 As shown, in some embodiments, the waterway structure 500 includes an air inlet pipe 550 .

[0124] The air inlet pipe 550 is used to transport the steam generated by the steam generator 530 into the cooking cavity.

[0125] The air inlet pipe 550 is located in the inner cavity and is communicated with the air outlet 532 and the cooking cavity.

[0126] In some embodiments, the material of the air inlet pipe 550 can be metal, rubber, silicone, etc. For example, the air inlet pipe 550 can be a silicone rubber hose.

[0127] During operation, the liquid is transported to the steam generator 530 through the water inlet pump 520 , and the steam generated by the steam generator 530 enters the inner container 200 through the air inlet pipe 550 .

[0128] After the steam cooking is finished, the liquid remaining in the steam generator 530 is transported to the water tank 510 through the drain pump 540. The user can then pour out the water in the water box to complete the cleaning.

[0129] After the steam generator 530 has been used for a period of time, scale will form on the inner wall of the steam generator 530. If the scale is not removed, it will become more and more, blocking the steam generator 530 pipeline and affecting normal use. At this time, a descaling agent needs to be used for descaling. The descaling agent needs to be dissolved in water and then soaked to achieve descaling.

[0130] To descaling, the prepared descaling agent is placed in the water tank 510, and the descaling mode is activated. The descaling agent is pumped into the steam generator 530 by the water inlet pump 520, and the descaling agent fills the entire steam generator 530 pipeline to soak and descaling. After descaling is completed, the drain pump 540 is activated to pump the descaling agent back into the water tank 510 for collection, making it easier for the user to clean. If there is no drain pump 540, fresh water must be pumped in again to flush the descaling agent into the cooking pot 200, and then the user must clean the pot 200, which is less convenient.

[0131] In some embodiments, at least a portion of the air inlet pipe 550 is located above the air outlet 532 .

[0132] It is understandable that if the air inlet pipe 550 is lower than the outlet of the steam generator 530 as a whole, the descaling agent water level will reach the air outlet 532 of the steam generator 530 and will flow away through the air inlet pipe 550, and will not be able to soak into the air outlet 532 of the steam generator 530, and the scale at the air outlet 532 of the steam generator 530 cannot be removed.

[0133] Therefore, the air inlet pipe 550 has a section higher than the air outlet 532 of the steam generator 530 , so that the descaling agent can soak into the air outlet 532 of the steam generator 530 and effectively remove the scale at the air outlet 532 of the steam generator 530 .

[0134] See also Figures 3 to 6 As shown, in some embodiments of the present application, part of the air inlet pipe 550 is located above the air outlet 532. Along the first direction, the distance between the part of the air inlet pipe 550 located above the air outlet 532 and the air outlet 532 is not less than the diameter of the air inlet pipe 550.

[0135] The first direction is the height direction of the housing 100 .

[0136] Specifically, the distance from the air outlet 532 along the first direction may be the distance between a top tangent line of the air outlet 532 and a top tangent line of the uppermost portion of the air inlet pipe 550 along the first direction.

[0137] It is understandable that when the maximum distance between the air inlet pipe 550 and the air outlet 532 along the first direction is smaller than the diameter of the air inlet pipe 550 , the retention effect of the descaling agent is poor and the air outlet 532 may not be fully soaked.

[0138] See also Figures 3 to 6 As shown, in some embodiments of the present application, the water tank 510 is located above the water inlet pump 520. In this way, the water inlet pump 520 can use the gravity of the water flow during the water pumping process, which is beneficial to energy saving.

[0139] In some embodiments, the steam generator 530 is located below the water inlet pump 520. In this way, the water inlet pump 520 can use the gravity of the water flow to transport water to the steam generator 530, which is conducive to energy saving.

[0140] In some embodiments, the water tank 510 is located above the drain pump 540 .

[0141] In some embodiments, the steam generator 530 is located below the drain pump 540 .

[0142] See also Figures 3 to 6 As shown, in some embodiments of the present application, the inner liner 200 is configured with an air inlet 210 , which is close to the bottom of the inner liner 200 and is connected to the air inlet pipe 550 .

[0143] It is understandable that the temperature of the steam is relatively high and it flows upward after entering the inner liner 200 . Setting the air inlet 210 near the bottom of the inner liner 200 is beneficial to improving the temperature uniformity in the inner liner 200 .

[0144] See also Figures 3 to 6 As shown, in some embodiments of the present application, the water tank 510 is located on the top of the inner tank 200, and the water inlet pump 520, the drain pump 540, the steam generator 530 and the air inlet pipe 550 are located on the back of the inner tank 200.

[0145] In this way, compared with setting the water tank 510, the water inlet pump 520, the drainage pump 540, the steam generator 530 and the air inlet pipe 550 on the top of the inner tank 200, the flexibility of the position setting is higher.

[0146] See also Figures 3 to 6 As shown, in some embodiments of the present application, a back plate 600 is further included, and the back plate 600 is arranged on the back of the inner liner 200.

[0147] The back plate 600 can be used to install components located at the back of the inner liner 200 .

[0148] The water inlet pump 520 , the water outlet pump 540 , the steam generator 530 and the air inlet pipe 550 are located on a side of the rear plate 600 away from the inner tank 200 .

[0149] The water inlet pump 520 , the water outlet pump 540 , the steam generator 530 , and the air inlet pipe 550 may be connected and positioned with the rear panel 600 .

[0150] In some embodiments, the back plate 600 is configured with a relief area 610 for avoiding the air inlet 210 , so as to facilitate the connection between the air inlet duct 550 and the air inlet 210 of the liner 200 .
