Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a cooking device. Background Technology

[0002] Traditional steam ovens and other steam cooking equipment are mostly open-loop systems, typically equipped with steam vents. During cooking, a large amount of steam is used once and then directly released into the external environment through these vents. This not only leads to a significant waste of heat energy but also increases the temperature and humidity of the external environment, negatively impacting the user experience. Although some steam ovens vent steam directly into the water tank for heat exchange with the water, insufficient condensation still results in some steam being released into the external environment. Utility Model Content

[0003] Therefore, it is necessary to provide a cooking device to reduce steam exhaust in order to address the above problems.

[0004] This utility model provides a cooking device, including: an inner pot having a cooking cavity and a steam inlet and a steam outlet communicating with the cooking cavity; a steam generating assembly for generating steam, the outlet of the steam generating assembly communicating with the steam inlet; a water tank assembly having a water storage cavity; and a condensing assembly including a condenser tube disposed in the water storage cavity, the inlet and outlet of the condenser tube communicating with the steam outlet and the water storage cavity, respectively.

[0005] In the aforementioned cooking equipment, the steam generated by the steam generating component enters the cooking chamber through the outlet and inlet of the steam generating component. After the cooking chamber is filled with steam, excess steam can be discharged into the condenser tube through the outlet and the inlet of the condenser tube. The condenser tube can fully condense the steam inside, allowing the steam to condense into liquid inside the condenser tube, and then flow into the water storage chamber through the outlet of the condenser tube. This reduces steam discharge, reduces heat energy waste, and avoids increasing the temperature and humidity of the external environment. Furthermore, since the condenser tube is located in the water storage chamber, when there is liquid in the water storage chamber, it can cool the steam inside the condenser tube, thereby improving the condensation rate and condensation effect.

[0006] In one embodiment, the water tank assembly includes a clean water tank and a return water tank, the inlet of the steam generating assembly is connected to the clean water tank, and the return water tank has the water storage chamber.

[0007] With this setup, the fresh water tank supplies cooking water to the steam generating unit, while the return water tank is used to recycle the condensate formed by the steam condensation.

[0008] In one embodiment, the water tank assembly includes a clean water tank and a water quality processor. The clean water tank has the water storage cavity, the inlet of the steam generating assembly is connected to the water storage cavity, and the water quality processor is disposed inside the water storage cavity.

[0009] With this setup, the clean water tank serves to both supply cooking water to the steam generating unit and recycle the condensate formed by steam condensation. After the condensate flows to the clean water tank, the water purifier can purify and soften the condensate, ensuring that the condensate meets the needs of cooking water and enabling the recycling of cooking water.

[0010] In one embodiment, the bottom wall of the water tank is provided with an outlet that communicates with the inlet of the steam generating assembly. The water tank assembly also includes a stop valve located at the outlet, which is used to control the opening and closing of the outlet.

[0011] This design prevents the cooking water in the fresh water tank from leaking out of the outlet when the fresh water tank is disassembled.

[0012] In one embodiment, the condenser tube includes a spiral section.

[0013] This design increases the overall length of the condenser tube and the contact area between the condenser tube and the liquid in the water storage chamber, thereby improving the condensation effect.

[0014] In one embodiment, the bottom wall of the water storage chamber is provided with a return water port communicating with the steam outlet, the inlet of the condenser tube is located in the return water port, and the condenser tube extends along the height direction of the water storage chamber.

[0015] This design prevents liquid in the water storage chamber from flowing back into the condenser tube through the outlet, allowing the water storage chamber to hold a sufficient amount of liquid. Furthermore, extending the condenser tube along the height of the water storage chamber increases the overall length of the condenser tube.

[0016] In one embodiment, the condensation assembly further includes a check valve located at the outlet of the condenser tube, the check valve being used to restrict the flow of liquid in the water storage chamber through the outlet of the condenser tube to the condenser tube.

[0017] With this design, the check valve can prevent liquid in the water storage chamber from flowing back into the condenser tube through the outlet of the condenser tube, ensuring the normal operation of the condenser assembly.

[0018] In one embodiment, the number of inner liner is at least two, the steam inlet of each inner liner is individually connected to the outlet of the steam generating component, and the steam outlet of each inner liner is connected to the inlet of the condenser pipe.

[0019] This setup allows users to select whether or not to use steam cooking for each inner pot as needed.

[0020] In one embodiment, the inner liner further includes a steam inlet valve disposed at the steam inlet, the steam inlet valve being used to restrict the flow of gas in the cooking cavity through the steam inlet to the steam generating assembly.

[0021] This design prevents the gas inside the cooking cavity from escaping through the steam inlet, which would reduce the amount of steam or lower the temperature inside the cooking cavity.

[0022] In one embodiment, the steam inlet and the steam outlet are respectively located on two opposite side walls of the inner liner in the horizontal direction, and the projection of the steam inlet on the side wall where the steam outlet is located is arranged at an interval from the steam outlet.

[0023] This design prevents steam from entering the cooking chamber through the steam inlet and then being directly discharged through the steam outlet, which would result in insufficient steam in the cooking chamber. Attached Figure Description

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application's specification are for illustrative purposes only and do not represent the only possible implementation.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0042] Traditional steam ovens and other steam cooking equipment are mostly open-loop systems, typically equipped with steam vents. During cooking, a large amount of steam is used once and then directly released into the external environment through these vents. This not only leads to a significant waste of heat energy but also increases the temperature and humidity of the external environment, negatively impacting the user experience. Although some steam ovens vent steam directly into the water tank for heat exchange with the water, insufficient condensation still results in some steam being released into the external environment.

[0043] To solve the above problems, such as Figures 1 to 11 As shown, this utility model provides a cooking device to reduce steam exhaust.

[0044] like Figure 1 and Figure 10 As shown, specifically, the cooking equipment includes an inner pot 10, a steam generating assembly 20, a water tank assembly 30, and a condensing assembly 40, wherein: the inner pot 10 has a cooking cavity 11 and a steam inlet 12 and a steam outlet 13 communicating with the cooking cavity 11; the steam generating assembly 20 is used to generate steam, and the outlet of the steam generating assembly 20 is communicating with the steam inlet 12; the water tank assembly 30 has a water storage cavity 31; the condensing assembly 40 includes a condenser pipe 41 disposed in the water storage cavity 31, and the inlet and outlet of the condenser pipe 41 are respectively communicating with the steam outlet 13 and the water storage cavity 31.

[0045] In the cooking device provided in this embodiment of the utility model, the steam generated by the steam generating component 20 enters the cooking chamber 11 through the outlet and inlet 12 of the steam generating component 20. After the cooking chamber 11 is filled with steam, the excess steam can be discharged into the condenser tube 41 through the outlet 13 and the inlet of the condenser tube 41. The condenser tube 41 can fully condense the steam inside, so that the steam can be condensed into liquid in the condenser tube 41 and then flow into the water storage chamber 31 through the outlet of the condenser tube 41. This can reduce steam discharge, reduce heat energy waste, and avoid causing the external ambient temperature and humidity to rise. Furthermore, since the condenser tube 41 is located in the water storage chamber 31, when there is liquid in the water storage chamber 31, it can play a water cooling role for the steam in the condenser tube 41, thereby improving the condensation rate and condensation effect.

[0046] It is worth mentioning that the cooking device includes a housing 16 and a door 15 that is rotatably connected to the housing 16 to close or open the housing 16, and the space inside the housing 16 forms a cooking cavity 11; or when the door is closed, the door 15 and the housing 16 enclose the cooking cavity 11.

[0047] like Figure 5 As shown, in one embodiment, the water tank assembly 30 includes a fresh water tank 32 and a return water tank 33. The inlet of the steam generating assembly 20 is connected to the fresh water tank 32, and the return water tank 33 has a water storage chamber 31. The fresh water tank 32 is used to provide cooking water to the steam generating assembly 20, and the return water tank 33 is used to recover the condensate formed by steam condensation. At this time, the liquid or steam flows sequentially along the fresh water tank 32, the steam generating assembly 20, the cooking chamber 11, the condensing assembly 40, and the return water tank 33. Specifically, both the fresh water tank 32 and the return water tank 33 include a detachable tank body 35 and a cover 36 to facilitate the user adding cooking water to the fresh water tank 32 and emptying the condensate in the return water tank 33. The fresh water tank 32 and the return water tank 33 may also be equipped with structures such as a water level gauge and a water level alarm to remind the user to add or empty water.

[0048] In another embodiment, the water tank assembly 30 includes a clean water tank 32 and a water quality processor. The clean water tank 32 has a water storage chamber 31, and the inlet of the steam generating assembly 20 is connected to the water storage chamber 31. The water quality processor is located inside the water storage chamber 31. The clean water tank 32 is used to supply cooking water to the steam generating assembly 20 and to recover condensate formed by steam condensation. Since the steam may be contaminated after passing through the cooking chamber 11 and the condenser pipe 41, the water quality processor can purify and soften the condensate after it flows to the clean water tank 32, so that the condensate meets the needs of cooking water and realizes the recycling of cooking water. At this time, the liquid or steam circulates sequentially along the clean water tank 32, the steam generating assembly 20, the cooking chamber 11, the condenser assembly 40, and the clean water tank 32. Furthermore, while the liquid in the clear water tank 32 cools the steam in the condenser tube 41, the steam in the condenser tube 41 also preheats the liquid in the clear water tank 32. This raises the temperature of the liquid in the clear water tank 32 before it enters the steam generating assembly 20, thereby improving the efficiency of steam generation by the steam generating assembly 20 and further reducing heat energy waste. Compared to the existing method of directly introducing the steam to be discharged into the water tank, which may contain impurities such as oil stains and easily contaminate the water quality in the tank, this method is much more effective.

[0049] Of course, in other embodiments, the water tank assembly 30 may only include a return water tank 33, which has a water storage chamber 31 and is used to recover condensate formed by steam condensation. The inlet of the steam generating assembly 20 is connected to an external water source to provide cooking water to the steam generating assembly 20 through the external water source.

[0050] like Figures 3 to 4 As shown, the bottom wall of the clean water tank 32 is provided with an outlet 321 that communicates with the inlet of the steam generating assembly 20. The water tank assembly 30 also includes a stop valve 34 located at the outlet 321, which controls the opening and closing of the outlet 321. When the clean water tank 32 is installed, the stop valve 34 opens, allowing the outlet 321 to open and communicate with the steam generating assembly 20, so that the cooking water in the clean water tank 32 can flow to the steam generating assembly 20 through the outlet 321. When the clean water tank 32 is disassembled, the stop valve 34 closes, closing the outlet 321 to prevent leakage of the cooking water in the clean water tank 32.

[0051] like Figure 4As shown, in one embodiment, the bottom wall of the clean water tank 32 is provided with a groove 322 communicating with the water outlet 321. The stop valve 34 includes a hollow valve body 341, a first sealing element 342, and a first elastic element 343. The valve body 341 is vertically and flexibly disposed in the groove 322. The first sealing element 342 is disposed at the top of the valve body 341 and is used to seal the water outlet 321. The side wall of the valve body 341 is provided with a water outlet hole 344. The first elastic element 343 is disposed between the end wall of the valve body 341 and the groove 322. When the valve body 341 rises, the first elastic element 343 is compressed. The cooking equipment also includes a water tank mounting bracket 50. The water tank mounting bracket 50 includes a hollow protrusion 51 and a second sealing element 52. The protrusion 51 is arranged correspondingly to the valve body 341. The second sealing element 52 covers the outer periphery of the protrusion 51. The bottom of the protrusion 51 is connected to the inlet of the steam generating assembly 20 through a pipe. When the clean water tank 32 is installed on the water tank mounting bracket 50, the protrusion 51 pushes the valve body 341 upward. The second seal 52 seals the gap between the protrusion 51 and the valve body 341, and the first seal 342 separates from the outlet 321. The cooking water in the clean water tank 32 can flow to the steam generating assembly 20 through the outlet 344, the valve body 341, the protrusion 51, and the pipeline. When the clean water tank 32 is disassembled, the valve body 341 descends under the elastic force of the first elastic member 343, causing the first seal 342 to seal the outlet 321. Of course, in other embodiments, the stop valve 34 can also be other mechanical valves or electronic control valves that can control the opening and closing of the outlet 321. This embodiment of the present invention does not impose specific limitations here.

[0052] like Figure 7 , Figure 8 and Figure 10 As shown, in one embodiment, there are at least two inner liner 10s. The steam inlet 12 of each inner liner 10 is individually connected to the outlet of the steam generating assembly 20, and the steam outlet 13 of each inner liner 10 is connected to the inlet of the condenser pipe 41. Thus, since the steam inlet 12 of each inner liner 10 and the outlet of the steam generating assembly 20 are independent and do not interfere with each other, it is possible to select whether each inner liner 10 uses steam cooking as needed. Of course, in other embodiments, the number of inner liner 10 can also be one.

[0053] like Figure 7As shown, specifically, the steam generating assembly 20 includes a steam generator 21, a water pump 22, and solenoid valves 23. The number of solenoid valves 23 is the same as the number of inner tanks 10, and they are arranged one-to-one with each inner tank 10. The inlet of the water pump 22 is connected to the outlet 321 of the clean water tank 32 via a pipeline, and the outlet of the water pump 22 is connected to the inlet of the steam generator 21 via a pipeline. The inlet of each solenoid valve 23 is connected to the outlet of the steam generator 21 via a pipeline, and the outlet of each solenoid valve 23 is connected to the steam inlet 12 of the corresponding inner tank 10 via a pipeline. When one of the inner tanks 10 needs to be steam-cooked, the water pump 22, the steam generator 21, and the corresponding solenoid valve 23 operate to introduce the steam generated by the steam generator 21 into the corresponding cooking chamber 11. The steam outlet 13 of each inner tank 10 is connected to the inlet of the condenser pipe 41 via a pipeline. The steam generator 21 can be a heating element such as a disc generator, an instantaneous generator, or a membrane generator, and over-temperature protectors are provided at both ends of the circuit of the steam generator 21. In addition, the water pump 22 can regulate the amount of water entering the steam generator 21, the solenoid valve 23 can regulate the amount of steam entering the cooking chamber 11, and the steam generating assembly 20 may also include other steam regulating elements such as control valves and steam-water separators.

[0054] like Figure 1 , Figure 3 and Figure 7 As shown, the X-axis is defined as the front-to-back direction of the cooking equipment, where the +X direction is the rear of the cooking equipment; the Y-axis is the width direction of the cooking equipment; and the Z-axis is the height direction of the cooking equipment. The steam generating assembly 20 and the water tank assembly 30 are both located at the rear of the inner liner 10. This fully utilizes the space at the rear of the cooking equipment. Especially when there are two or more inner liners 10, which are typically stacked along the height of the cooking equipment, placing the steam generating assembly 20 and the water tank assembly 30 at the rear of the inner liner 10 avoids increasing the dimensions of the cooking equipment along the height or width directions. It also ensures that the steam inlet 12 and steam outlet 13 of each inner liner 10 can easily connect to the steam generating assembly 20 and the condenser pipe 41.

[0055] like Figures 8 to 9 As shown, the inner liner 10 also includes a steam inlet valve 14 located at the steam inlet 12. The steam inlet valve 14 is used to restrict the flow of gas in the cooking chamber 11 through the steam inlet 12 to the steam generating assembly 20. The steam inlet valve 14 can prevent the gas in the cooking chamber 11 from being discharged through the steam inlet 12, which would reduce the amount of steam or lower the temperature in the cooking chamber 11, thereby ensuring the normal operation of the cooking equipment.

[0056] like Figure 9As shown, in one embodiment, the steam inlet valve 14 includes a first valve seat 141, a first valve body 142, a valve core 143, a second elastic element 144 and a third sealing element 145. The side wall of the first valve body 142 is provided with a steam inlet hole 146 communicating with the cooking chamber 11. The first valve seat 141 passes through the steam inlet 12 from the outside of the inner liner 10 and is fixedly connected to the first valve body 142 in the cooking chamber 11. The valve core 143 is slidably disposed in the first valve body 142 and can open or block the communication port between the first valve seat 141 and the first valve body 142. The second elastic member 144 is disposed between the valve core 143 and the first valve body 142. When the valve core 143 slides to open the communication port between the first valve seat 141 and the first valve body 142, the second elastic member 144 is compressed. The end of the first valve seat 141 located outside the inner liner 10 is connected to the outlet of the corresponding solenoid valve 23. The third sealing member 145 is disposed between the edge of the first valve seat 141 and the steam inlet 12 to prevent steam leakage. When the steam in the first valve seat 141 reaches a certain pressure, it can push open the valve core 143, causing the valve core 143 to slide open the communication port between the first valve seat 141 and the first valve body 142. Steam can then enter the cooking chamber 11 through the communication port between the first valve seat 141 and the first valve body 142 and the steam inlet 146. When the gas pressure in the first valve seat 141 decreases, the valve core 143 can slide and seal the communication port between the first valve seat 141 and the first valve body 142 under the elastic force of the second elastic element 144. Of course, in other embodiments, the steam inlet valve 14 can also be other mechanical valves or electronic control valves that can control the opening and closing of the steam inlet 12. This embodiment of the present invention does not impose specific limitations here.

[0057] like Figures 10 to 11 As shown, the inner liner 10 also includes a steam outlet valve 17 located at the steam outlet 13. The steam outlet valve 17 includes a second valve seat 171, a second valve body 172, and a fourth sealing element 173. The second valve seat 171 passes through the steam outlet 13 from the outside of the inner liner 10 and is fixedly connected to the second valve body 172 within the cooking chamber 11. One end of the second valve seat 171 located outside the inner liner 10 is connected to the inlet of the corresponding condenser pipe 41 via a pipeline. The second valve body 172 is connected to the cooking chamber 11. The fourth sealing element 173 is located between the edge of the second valve seat 171 and the steam outlet 13 to prevent steam leakage. Here, the steam outlet valve 17 is only used to connect the pipeline to the steam outlet 13. Of course, the steam outlet valve 17 can also be a mechanical valve or an electronically controlled valve, etc., capable of controlling the opening and closing of the steam outlet 13. This embodiment of the present invention does not impose specific limitations here.

[0058] like Figure 1 and Figure 6As shown, in one embodiment, the condenser tube 41 includes a spiral section 411. The spiral section 411 can increase the overall length of the condenser tube 41 and increase the contact area between the condenser tube 41 and the liquid in the water storage chamber 31, thereby further improving the condensation effect. In another embodiment, the condenser tube 41 includes a spiral section 411 and an extension section 412 at the end of the spiral section 411 away from the inlet of the condenser tube 41. The extension section 412 extends along the height direction of the water storage chamber 31, thereby further extending the overall length of the condenser tube 41. Of course, in other embodiments, the condenser tube 41 can also be in other shapes such as straight or serpentine, as long as it can condense the vapor in the condenser tube 41. This embodiment of the present invention does not impose specific limitations. The condenser tube 41 can be a metal tube made of a high thermal conductivity material, and the condensation assembly 40 can also include other auxiliary heat dissipation structures such as metal fins to improve condensation efficiency and condensation effect.

[0059] like Figures 1 to 2 As shown, the bottom wall of the water storage chamber 31 is provided with a return water port 311 communicating with the steam outlet 13. The inlet of the condenser tube 41 is located inside the return water port 311, and the condenser tube 41 extends along the height direction of the water storage chamber 31. In this way, the outlet of the condenser tube 41 is located above the inlet, which can prevent the liquid in the water storage chamber 31 from flowing back into the condenser tube 41 through the outlet of the condenser tube 41. This allows the water storage chamber 31 to hold a sufficient amount of liquid to ensure the normal operation of the condenser assembly 40. Furthermore, the extension of the condenser tube 41 along the height direction of the water storage chamber 31 can also increase the overall length of the condenser tube 41.

[0060] like Figure 2 As shown, the condenser assembly 40 also includes a bushing 44 located at the return water port 311, with the inlet of the condenser pipe 41 inserted into the bushing 44. A sheet metal part 60 is provided on the rear side of the inner liner 10 to isolate the inner liner 10 from the steam generating assembly 20 and the water tank assembly 30. The condenser assembly 40 also includes a connecting valve 43, which includes a third valve seat 431, a third valve body 432, and a fifth seal 433. The third valve seat 431 passes through the sheet metal part 60 and is fixedly connected to the third valve body 432. The steam outlet 13 of each inner liner 10 is connected to the third valve seat 431 via a pipe, and the third valve body 432 is connected to the return water port 311 via a pipe. The fifth seal 433 is located between the third valve body 432 and the sheet metal part 60 to prevent steam leakage. The connecting valve 43 here is only used to connect the steam outlet 13 and the return water port 311 of each inner liner 10.

[0061] like Figure 1 and Figure 6As shown, the condenser assembly 40 also includes a check valve 42 located at the outlet of the condenser tube 41. The check valve 42 is used to restrict the flow of liquid in the water storage chamber 31 through the outlet of the condenser tube 41 to the condenser tube 41. The check valve 42 can also prevent the liquid in the water storage chamber 31 from flowing back into the condenser tube 41 through the outlet of the condenser tube 41, ensuring the normal operation of the condenser assembly 40.

[0062] like Figure 10 As shown, the steam inlet 12 and the steam outlet 13 are respectively located on opposite side walls of the inner liner 10 in the horizontal direction, preferably... Figure 10 As shown in the Y-axis direction, the projection of the steam inlet 12 onto the side wall where the steam outlet 13 is located is spaced apart from the steam outlet 13. That is, the projection of the steam inlet 12 onto the side wall where the steam outlet 13 is located does not coincide with the steam outlet 13 at all. This is to prevent steam from entering the cooking chamber 11 through the steam inlet 12 and then being directly discharged through the steam outlet 13, resulting in insufficient steam in the cooking chamber 11. This ensures that the steam entering the cooking chamber 11 through the steam inlet 12 can fill the cooking chamber 11 before being discharged through the steam outlet 13.

[0063] The cooking equipment may also include a temperature control component located inside the cooking cavity 11 or outside the inner pot 10. The temperature control component may include structures such as heating tubes, heating films, fans, and temperature measuring elements, so as to accurately control the temperature inside the cooking cavity 11 and realize multiple cooking modes such as steaming, baking, or steam-baking fusion of the cooking equipment to meet the cooking needs of different ingredients.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
