[0029] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0031] In the description of the present application, terms such as "first", "second", "third", "fourth", etc. (if any) in the specification, claims and the above - mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order different from those illustrated or described herein.

[0032] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0033] In addition, the terms "arranged", "connected", and "fixed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0034] Unless otherwise specified, the term "plurality" means two or more.

[0035] As can be seen from the background art, after cooking, the condensed water accumulated on the bottom wall of the inner container of the steaming and baking device, as well as the remaining water accumulated in the steam generator, need to be cleaned by the user in a timely manner. Otherwise, the long-term retention of this remaining water and condensed water will cause bacterial growth, affect the sanitation effect of the steaming and baking device, and may also rust the inner wall of the steam generator and the inner container, affecting the user experience.

[0036] The existing cleaning of the remaining water and condensed water needs to wait until the device is completely cooled before proceeding to avoid the situation of high-temperature scalding. Among them, the user needs to use tools such as a rag or a paper towel to manually wipe the inner container to remove the condensed water on the inner container, and also needs to manually open the drain valve of the steam generator to drain the remaining water, and use a container to receive the drained remaining water. This manual cleaning method is relatively cumbersome.

[0037] There are also some steam generators of steaming and baking devices that do not have a drainage function, and the user cannot operate by themselves to drain the remaining water inside the steam generator, and professional maintenance is required regularly to clean it. Therefore, it is more difficult to ensure the cleaning effect inside the steam generator.

[0038] Thus, it can be seen that the condensed water and the remaining water in the existing steaming and baking devices need to be manually cleaned by the user, which is easy to be forgotten and there is a problem of inconvenient cleaning.

[0039] To solve the above problems, the present application provides a steaming and baking device, which includes a water storage box, a steam generator, an inner container, and a pump body; the water storage box includes a first water storage box body and a second water storage box body; the steam generator is communicated with the inner container; the steam generator has a water inlet and a first drain port, and the inner container has a second drain port; the pump body is communicated with the first water storage box body, the second water storage box body, the water inlet, the first drain port, and the second drain port. In the cooking state, the pump body communicates the first water storage box body and the water inlet, and conveys the water in the first water storage box body into the steam generator; in the non-cooking state, the pump body communicates the first drain port and the second water storage box body to convey the remaining water in the steam generator to the second water storage box body, and at the same time the pump body also communicates the second drain port and the second water storage box body to convey the condensed water in the inner container to the second water storage box body, achieving the recycling effect of the remaining water and the condensed water, without the need for the user to manually clean, and solving the problem of inconvenient cleaning of the steaming and baking device.

[0040] The following uses specific embodiments to detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. These several specific embodiments below can exist independently or be combined with each other. For the same or similar concepts or processes, they may not be repeated in some embodiments. The following will describe the embodiments of the present application with reference to the drawings.

[0041] Figure 1 It is a schematic connection structure diagram of the steaming and baking device provided by the embodiment of the present application. Combining Figure 1 As shown, the present application provides a steaming and baking device, which includes a water storage box 100, a steam generator 200, an inner container 300, and a pump body 400; the water storage box 100 includes a first water storage box body 110 and a second water storage box body 120; the steam generator 200 is communicated with the inner container 300; the steam generator 200 has a water inlet 220 and a first drain port 230, and the inner container 300 has a second drain port 320; the pump body 400 is communicated with the first water storage box body 110, the second water storage box body 120, the water inlet 220, the first drain port 230, and the second drain port 320; the pump body 400 is configured to communicate the first water storage box body 110 and the water inlet 220 in the cooking state, and convey the water in the first water storage box body 110 into the steam generator 200; in the non-cooking state, it communicates the first drain port 230 and the second water storage box body 120 and the second drain port 320 and the second water storage box body 120, and conveys the remaining water in the steam generator 200 and the condensed water in the inner container 300 to the second water storage box body 120.

[0042] It should be noted that the steaming and baking device can be a commercial or household cooking device such as a steam oven or a steamer that can realize the steaming function of food; it can be an embedded device installed in a cabinet or a movable tabletop device.

[0043] The steaming and baking device also has a housing, and the inner container 300 is arranged inside the housing. A hanging rack for placing a steaming tray can be arranged on the side wall of the inner container 300, and the food to be cooked is placed on the steaming tray, or the food to be cooked can also be directly placed on the bottom wall of the inner container 300. There is an installation space between the inner container 300 and the housing for accommodating the water storage box 100, the steam generator 200, the inner container 300, the pump body 400, as well as water pipes, air pipes, and circuits, etc.

[0044] Among them, the first water storage box body 110 and the second water storage box body 120 can be integrated or separated. The first water storage box body 110 is used to accommodate cooking water, and the second water storage box body 120 is used to accommodate the recycled residual water and condensed water.

[0045] In the cooking state of the steaming and baking device provided by the embodiment of the present application, the pump body 400 can communicate with the water inlet 220 of the first water storage box body 110 and the steam generator 200, and the operation of the pump body 400 can transport the cooking water in the first water storage box body 110 into the steam generator 200, so as to facilitate the steam generator 200 to generate steam; an exhaust port 210 is provided on the steam generator 200, and an air inlet 310 is provided on the inner container 300. The exhaust port 210 and the air inlet 310 are connected through a steam pipe, and the steam generated by the steam generator 200 can enter the inner container 300 through the steam pipe to cook the food placed in the inner container 300.

[0046] After cooking is completed, there is still some unused residual water in the steam generator 200, and the steam will cool and condense on the inner wall of the inner container 300 after contacting the inner wall of the inner container 300. In order to handle these residual water and condensed water, in the non-cooking state, the pump body 400 can communicate with the first drain port 230 and the second water storage box body 120, as well as the second drain port 320 and the second water storage box body 120, and the operation of the pump body 400 can transport the residual water in the steam generator 200 and the condensed water in the inner container 300 to the second water storage box body 120, achieving the effect of recycling the residual water and condensed water, without the need for the user to manually clean after use, and solving the problem of inconvenient cleaning of the steaming and baking device.

[0047] Further, a fifth valve body 231 is also provided at the first drain port 230, and the fifth valve body 231 is preferably an electromagnetic valve. The first drain port 230 is communicated with the input end of the fifth valve body 231, and the output end of the fifth valve body 231 is communicated with the pump body 400; the fifth valve body 231 is used to control the opening and closing of the first drain port 230, thereby controlling the discharge of the remaining water in the steam generator 200. In the cooking state, the fifth valve body 231 is closed, which is equivalent to closing the first drain port 230. Under the action of the pump body 400, water can be stored in the steam generator 200. The steam generator 200 can heat the water inside to generate steam and transport it to the inner tank 300 to cook food; in the non-cooking state, the steam generator 200 no longer needs to generate steam. At this time, the fifth valve body 231 is opened, which is equivalent to opening the first drain port 230. The remaining water in the steam generator 200 can be discharged through the first drain port 230 to prevent it from accumulating in the steam generator 200.

[0048] Among them, the first drain port 230 is preferably arranged at the bottom of the steam generator 200, so that when the fifth valve body 231 is opened, the remaining water inside the steam generator 200 flows downward under the action of gravity and is discharged from the steam generator 200 through the first drain port 230.

[0049] In some embodiments, the pump body 400 is a two-way pump.

[0050] It should be noted that a two-way pump is a pump body with two-way conveying ability. The specific structure of the two-way pump is a known structural design method in the art and will not be elaborated here.

[0051] Specifically, in the cooking state, the two-way pump is in the forward working state, which can connect the first water storage box body 110 and the water inlet 220, and transport the water in the first water storage box body 110 to the steam generator 200; in the non-cooking state, the two-way pump is in the reverse working state, which can connect the first drain port 230 and the second water storage box body 120 as well as the second drain port 320 and the second water storage box body 120, and transport the remaining water in the steam generator 200 and the condensed water in the inner tank 300 to the second water storage box body 120.

[0052] In the non-cooking state, the two-way pump can be set to be periodically turned on, that is, it runs once every first preset time period, and the running time each time is the second preset time period. In this way, not only can the remaining water and condensed water be discharged, but the two-way pump does not have to run all the time, which has the effect of energy saving while ensuring the drainage process. The specific first preset time period and second preset time period can be set according to actual needs, and the present application does not limit this.

[0053] By setting the pump body 400 as a two-way pump, only one pump body 400 is needed to achieve the water inlet of the steam generator 200 and the drainage effect of the remaining water and condensate, which helps to save the installation space inside the oven device and simplify the layout of the control circuit.

[0054] In some other embodiments, the two-way pump includes a motor and two pump heads connected to the motor. One pump head is communicated with both the first water storage box body 110 and the water inlet 220, and the other pump head is communicated with the second water storage box body 120, the first drain port 230 and the second drain port 320. When in the cooking state, the motor rotates forward to drive the pump head communicated with the first water storage box body 110 and the water inlet 220 to operate, so as to supply water to the steam generator 200. When in the non-cooking state, the motor rotates reversely to drive the pump head communicated with the second water storage box body 120, the first drain port 230 and the second drain port 320 to operate, so as to transport the remaining water recovered from the steam generator 200 and the condensate recovered from the inner container 300 to the second water storage box body 120.

[0055] Exemplarily, both of the two pump heads can be diaphragm pump heads, or both can be impeller pump heads, or one is a diaphragm pump head and the other is an impeller pump head.

[0056] Figure 2 Another connection structure schematic diagram of the steaming and baking device provided by the embodiment of the present application;

[0057] Figure 3 For Figure 2 the enlarged view of part A in. Combining Figure 2 and Figure 3 As shown, in some embodiments, the pump body 400 has a first interface 410 and a second interface 420. The first interface 410 is communicated with the first water storage box body 110, and the second interface 420 is communicated with the water inlet 220. A first valve body 411 is connected to the first interface 410, and a second valve body 421 is connected to the second interface 420. The first valve body 411 and the second valve body 421 are used to limit the unidirectional flow of the water in the first water storage box body 110 through the pump body 400 to the steam generator 200 when the first water storage box body 110 and the water inlet 220 are communicated.

[0058] When specifically implemented, when the pump body 400 stores water in the steam generator 200, the cooking water flows from the first interface 410 of the pump body 400 to the second interface 420 when passing through the pump body 400.

[0059] In some embodiments, the first interface 410 communicates with the second water storage box body 120; the second interface 420 communicates with both the first drain port 230 and the second drain port 320; a third valve body 412 is connected to the first interface 410, and a fourth valve body 422 is connected to the second interface 420. The third valve body 412 and the fourth valve body 422 are configured to restrict the one-way flow of the remaining water in the steam generator 200 and the condensed water in the inner tank 300 through the pump body 400 to the second water storage box body 120 when both the first drain port 230 and the second drain port 320 communicate with the second water storage box body 120.

[0060] During specific implementation, when the pump body 400 recovers the remaining water and the condensed water to the second water storage box body 120, the remaining water and the condensed water flow from the second interface 420 of the pump body 400 to the first interface 410 when passing through the pump body 400.

[0061] Since the second interface 420 of the pump body 400 communicates with the water inlet 220, the first drain port 230, and the second drain port 320, the cooking water may flow to the first drain port 230 and the second drain port 320 after flowing out through the second interface 420. In the embodiments of the present application, by arranging the first valve body 411 and the second valve body 421 on the flow path of the cooking water, the flow of the cooking water to the water inlet 220 of the steam generator 200 after passing through the pump body 400 can be restricted, and it will not flow to the first drain port 230 of the steam generator 200 or the second drain port 320 of the inner tank 300, thereby ensuring the effectiveness of water inlet to the steam generator 200.

[0062] Since the first interface 410 of the pump body 400 communicates with both the first water storage box body 110 and the second water storage box body 120, the remaining water and the condensed water may flow to the first water storage box body 110 after flowing out through the first interface 410. In the embodiments of the present application, by arranging the third valve body 412 and the fourth valve body 422 on the recovery path of the remaining water and the condensed water, the flow of the remaining water and the condensed water to the second water storage box body 120 after passing through the pump body 400 can be restricted, and it will not flow to the first water storage box body 110 to prevent the remaining water and the condensed water from mixing with the cooking water.

[0063] In some embodiments, the first interface 410 is respectively connected to the first water storage box body 110 and the second water storage box body 120 through a first joint 413, and the first valve body 411 and the third valve body 412 are connected to the first joint 413.

[0064] Exemplarily, the first joint 413 is a three-way joint. The first valve body 411 is arranged at the connection port of the three-way joint corresponding to the first water storage box 100, and the second valve body 421 is arranged at the connection port of the three-way joint corresponding to the second water storage box 100.

[0065] By arranging the first valve body 411 and the third valve body 412 on the first joint 413, when the pump body 400 sucks the cooking water in the first water storage box 100, it is possible to avoid sucking the condensed water and residual water remaining in the water pipe between the second water storage box body 120 and the first interface 410, and avoid the mixing of the cooking water with the residual water and the condensed water.

[0066] In some embodiments, the second interface 420 is connected to the first drain port 230, the second drain port 320, and the water inlet 220 through the second joint 423, and the third valve body 412 and the fourth valve body 422 are connected to the second joint 423.

[0067] Exemplarily, the second joint 423 is a three-way joint, and the third valve body 412 is arranged at the connection port of the three-way joint corresponding to the water inlet 220; the water paths at the first drain port 230 and the second drain port 320 are merged into one path through the third joint, and the fourth valve body 422 is arranged at the connection port of the three-way joint corresponding to the third joint. Among them, the third joint is also a three-way joint.

[0068] In some other embodiments, the second joint 423 is a four-way joint, and the third valve body 412 is arranged at the connection port of the four-way joint corresponding to the water inlet 220; there are two fourth valve bodies 422, one fourth valve body 422 is arranged at the connection port of the four-way joint corresponding to the first drain port 230, and the other fourth valve body 422 is arranged at the connection port of the four-way joint corresponding to the second drain port 320.

[0069] By arranging the third valve body 412 and the fourth valve body 422 on the second joint 423, when the pump body 400 sucks the residual water and the condensed water, it is possible to avoid sucking the cooking water remaining in the water pipe between the steam generator 200 and the second interface 420.

[0070] In some embodiments, the first valve body 411, the second valve body 421, the third valve body 412, and the fourth valve body 422 are all one-way valves.

[0071] It should be noted that the liquid passing through the one-way valve can only flow in from the inlet end of the one-way valve and flow out from the outlet end of the one-way valve, and cannot flow in the reverse direction. Therefore, the one-way valve is also called a check valve or a non-return valve. The one-way valve in the embodiments of the present application can adopt various ordinary micro one-way valves to reduce the occupation of the internal installation space of the steaming and baking equipment and also reduce the cost.

[0072] Figure 4 For Figure 1 is a schematic structural diagram of the inner container 300. Combining Figure 4 As shown, in some embodiments, the bottom wall of the inner container 300 has at least one inclined surface, the inclined surface forms a diversion part 330, and the second drain port 320 is opened at the lowest part of the diversion part 330.

[0073] By providing a guide portion 330 on the bottom wall of the inner tank 300 , the condensed water can be guided so that the condensed water flows along the guide portion 330 to the lowest point of the guide portion 330 and then is discharged from the second drain port 320 provided at the lowest point.

[0074] Combination Figure 4 As shown, when the bottom wall of the inner tank has multiple inclined surfaces, the inclined surfaces are arranged to form a prism-shaped structure, the side length of the lower bottom surface of the prism-shaped structure is smaller than the side length of the upper bottom surface, and the second drain outlet 320 is arranged on the lower bottom surface of the prism-shaped structure. The side of the prism-shaped structure can provide guidance for the flow of condensed water.

Figure 5 As shown, when the bottom wall of the inner tank 300 has only one inclined surface, the inclined surface is an arc-shaped surface, which is arranged to form a truncated cone structure. The diameter of the lower bottom surface of the truncated cone structure is smaller than the diameter of the upper bottom surface. The second drain outlet 320 is arranged on the lower bottom surface of the truncated cone structure, and the side of the truncated cone structure can provide guidance for the flow of condensed water.

[0076] Specifically, the guide portion 330 in the embodiment of the present application may also be other structures as long as it can guide the condensed water to the second drain port 320 .

[0077] In some embodiments, a transfer box 500 is also included. The transfer box 500 is arranged below the bottom wall of the inner tank 300. The transfer box 500 has a first water inlet 510, a second water inlet 520 and a water outlet 530; the first water inlet 510 is connected to the first drain port 230; the second water inlet 520 is connected to the second drain port 320; the water outlet 530 is connected to the pump body 400.

[0078] The transfer box 500 can be set below the bottom wall of the inner tank 300, and the second water inlet 520 is set on the side wall of the transfer box 500, and the position of the second water inlet 520 is lower than the position of the second drain port 320. A recovery pipe is connected to the second water inlet 520, and the end of the recovery pipe away from the second water inlet 520 is connected to the second drain port 320. The recovery pipe is also set below the bottom wall of the inner tank 300, so as to utilize gravity to promote condensed water to flow into the transfer box 500 through the drain pipe.

[0079] In other embodiments, the transfer box 500 may also be directly disposed below the bottom wall of the inner tank 300 , and the second water inlet 520 is opened at the top of the transfer box 500 and corresponds to the second drain port 320 to receive condensed water flowing out through the second drain port 320 .

[0080] Further, the position of the first water inlet 510 is also lower than the position of the first drain outlet 230, so that when the steam generator 200 discharges the remaining water, the remaining water can flow into the transfer box 500 under the action of gravity.

[0081] By providing the transfer box 500, the remaining water discharged from the steam generator 200 and the condensed water discharged from the inner tank 300 can be collected, and then uniformly discharged into the second water storage box body 120 under the action of the pump body 400, improving the effectiveness and efficiency of drainage.

[0082] The remaining water and the condensed water are stored in the transfer box 500. The pump body 400 is communicated with the transfer box 500. The pump body 400 can also be periodically turned on in the cooking state of the steaming and baking device to perform reverse work to discharge the remaining water and the condensed water in the transfer box 500. The periodic turning-on manner of the pump body 400 has been described in detail in the above embodiments and will not be elaborated here.

[0083] In some embodiments, a water level detection member and a controller are further included. The water level detection member is arranged in the transfer box 500. Both the water level detection member and the pump body 400 are electrically connected to the controller; the water level detection member is used to transmit the water level information in the transfer box 500 to the controller, so that when the water level information is higher than the preset water level, the controller controls the pump body 400 to operate to communicate the first drain outlet 230, the second drain outlet 320 and the second water storage box body 120.

[0084] By arranging the water level detection member in the transfer box 500, the water level in the transfer box 500 can be monitored in real time, so as to timely discharge the remaining water and the condensed water collected in the transfer box 500. Exemplarily, the water level detection member is a liquid level sensor.
