[0027] Reference below Figure 1-Figure 3 The cooking device 100 according to an embodiment of the present invention is described. By setting a negative pressure valve assembly 31, the water pump 32 can supply water to the steam generating element 2 normally and stably, thereby improving the working stability of the steam generating element 2. The water pump 32 can automatically draw water, thereby reducing the workload of manual water replenishment. The water pump 32 has the function of drawing water as needed, thereby avoiding the problem of water quality degradation caused by long-term water storage and unused water, thereby improving the safety of water use, thereby improving the cooking quality, and the water pump 32 has a simple structure and good use effect.

[0028] like Figure 1-Figure 3 As shown, a cooking device 100 according to an embodiment of the present invention includes: a device body 1, a steam generating element 2 and a water supply pipeline 3.

[0029] A cooking cavity 14 and an installation cavity 11 are formed in the device body 1. Specifically, the cooking device 100 can be other types such as an air fryer, a steam oven, and a baking oven. The device body 1 is a shell structure of the cooking device 100, which includes a cooking cavity 14 and an installation cavity 11. The cooking cavity 14 is used to place food to be cooked, and the installation cavity 11 is used to install other structures of the cooking device 100. The installation cavity 11 and the cooking cavity 14 are distributed separately, and the structure in the installation cavity 11 can be separated from the cooking cavity 14.

[0030] The steam generating element 2 is installed in the installation cavity 11, and is provided with a water inlet 21 and a steam outlet 22. The steam outlet 22 is connected to the cooking cavity 14. One end of the water supply pipe 3 is connected to an external water source and the other end is connected to the water inlet 21. The water supply pipe 3 is provided with a negative pressure valve assembly 31 and a water pump 32 distributed in sequence along the water flow direction. The water pump 32 is suitable for pumping water from the negative pressure valve assembly 31 to the water inlet 21.

[0031] Specifically, a heating element is provided in the steam generating part 2, which is used to heat the water in the steam generating part 2 to form steam. The steam generating part 2 is detachably connected to the installation cavity 11. A water inlet 21 and a steam outlet 22 are provided at the end of the steam generating part 2. The water inlet 21 is connected to the outlet end of the water supply pipeline 3. The steam outlet 22 can be connected to the cooking cavity 14 through a delivery pipe or a delivery pipe, and the inlet end of the water supply pipeline 3 is connected to an external water source. Among them, the water supply pipeline 3 is provided with a negative pressure valve assembly 31 and a water pump 32. The negative pressure valve assembly 31 is used to generate a local negative pressure area in the water supply pipeline 3. The water pump 32 is used to pump water flow, and the water pump 32 is located downstream of the negative pressure valve assembly 31. The downstream of the water pump 32 is connected to the steam generating part 2. In this way, the water supply pipeline 3, the negative pressure valve assembly 31 and the water pump 32 can be connected to the steam generating part 2. The external water source can be a water supply device such as a water purifier, which can provide clean and safe water quality for the cooking device 100.

[0032] In this embodiment, the cooking device 100 can be used for baking food or steaming food. In the steaming food mode, the water flow direction is as follows: Figure 1 and Figure 2 As shown by the middle arrow, the external water source flows to the steam generating element 2 through the negative pressure valve assembly 31 and the water pump 32 in sequence, and the steam generated by the steam generating element 2 flows to the cooking cavity 14 to steam the food.

[0033] Therefore, by setting one end of the water supply pipeline 3 to be connected to the external water source and the other end to be connected to the steam generating element 2, and the water supply pipeline 3 is provided with a negative pressure valve assembly 31 and a water pump 32, automatic water extraction can be realized, the setting of the water storage box is reduced, and the work of manual water adding can also be reduced. The structure is simple and the cost is low. The setting of the negative pressure valve assembly 31 can flexibly and effectively reduce the pressure in the area, which can avoid leakage or greater damage due to excessive pressure, and improve the safety performance of the cooking device 100. After the water pressure in the water supply pipeline 3 remains stable, it is beneficial for the water pump 32 to stably pump water from the negative pressure valve assembly 31, which can ensure that the steam generating element 2 stably generates steam to ensure the continuity and cooking effect of cooking. When food needs to be steamed, the structure in the water supply pipeline 3 can be started. After steaming, the structure in the water supply pipeline 3 stops working, so that there will be no water accumulation, which can reduce the situation of water deterioration and improve the quality of water use.

[0034] According to the cooking device 100 of the embodiment of the present invention, by providing the negative pressure valve assembly 31, the water pump 32 can supply water to the steam generating element 2 normally and stably, thereby improving the working stability of the steam generating element 2. The water pump 32 can automatically take water, thereby reducing the workload of manual water replenishment. The water pump 32 has the function of taking water as needed, thereby avoiding the problem of water quality degradation caused by long-term water storage and unused water, thereby improving the safety of water use, thereby improving the cooking quality, and has a simple structure and good use effect.

[0035] In some embodiments, the water supply pipeline 3 runs through the equipment body 1, and the water supply pipeline 3 includes an internal water channel 33 and an external water channel 34. The internal water channel 33 is located in the installation cavity 11 and is connected to the water inlet 21, and the external water channel 34 is located outside the equipment body 1 and is connected to an external water source.

[0036] Specifically, the external waterway 34 and the internal waterway 33 can be configured as a connecting water pipe, one end of which can be directly connected to the external water source, and the other end of which is connected to the inlet end of the internal waterway 33. Figure 2 As shown, the external water circuit 34 is located on the outside of the equipment body 1, and the internal water circuit 33 is located in the installation cavity 11 of the equipment body 1. In this way, the water supply pipe 3 can pass through the equipment body 1, and the outlet end of the internal water circuit 33 is connected to the water inlet 21. Therefore, the cooking device 100 can be connected to the external water source through the external water circuit 34, and the internal water circuit 33 is responsible for guiding the water transported by the external water circuit 34 to the water inlet 21 of the steam generating part 2, ensuring that water is provided to the steam generating part 2, thereby generating steam.

[0037] Therefore, the installation cavity 11 provides an installation space for the internal water channel 33 and can hide and protect the structure of the internal water channel 33 , and is provided with two parts, the internal water channel 33 and the external water channel 34 , for easy installation and maintenance.

[0038] In some embodiments, the negative pressure valve assembly 31 and the water pump 32 are both disposed in the internal water channel 33 , and the negative pressure valve assembly 31 and the water pump 32 are fixed in the installation cavity 11 .

[0039] Specifically, the negative pressure valve assembly 31 and the water pump 32 are connected to the internal water channel 33 in sequence along the water flow direction. In this way, the negative pressure valve assembly 31 and the water pump 32 work at the same time, and the water in the external water channel 34 can be sucked to the steam generating element 2 through the internal water channel 33, and the suction process is safe and effective. The negative pressure valve assembly 31 and the water pump 32 are both located in the installation cavity 11, wherein the negative pressure valve assembly 31 and the water pump 32 can be detachably connected to the installation cavity 11, and can be connected and fixed by fasteners such as bolts, and the connection method is simple and easy to install.

[0040] Therefore, the negative pressure valve assembly 31 and the water pump 32 are both arranged in the installation cavity 11, which can protect the negative pressure valve assembly 31 and the water pump 32, prevent dust, humidity and other factors from damaging them, extend the service life of the negative pressure valve assembly 31 and the water pump 32, and keep the exterior of the equipment body 1 neat and clean.

[0041] In some embodiments, the internal water circuit 33 includes a first water pipe 331, a second water pipe 332 and a third water pipe 333 distributed in sequence along the water flow direction, the first water pipe 331 is connected to the external water circuit 34, the negative pressure valve assembly 31 is arranged between the first water pipe 331 and the second water pipe 332, the water pump 32 is arranged between the second water pipe 332 and the third water pipe 333, and the water outlet end of the third water pipe 333 is connected to the water inlet 21.

[0042] Specifically, Figure 2 and Figure 3 As shown, the first water pipe 331, the second water pipe 332 and the third water pipe 333 are connected in sequence along the water flow direction, and the water inlet end of the first water pipe 331 is connected to the external water channel 34, and the connection between the two passes through the equipment body 1, wherein the water outlet end of the first water pipe 331 and the water inlet end of the second water pipe 332 are connected with the negative pressure valve assembly 31, and the water outlet end of the second water pipe 332 and the water inlet end of the third water pipe 333 are connected with the water pump 32, and the water outlet end of the third water pipe 333 is connected with the water inlet 21, so that the distribution of the negative pressure valve assembly 31 and the water pump 32 can be realized, and the two ends of the internal water channel 33 can be respectively connected to the external water channel 34 and the steam generating element 2, and the overall structure is simple and convenient to connect.

[0043] Furthermore, in the steaming mode, the water flow direction is as follows: Figure 2 In the direction indicated by the middle arrow, after the water pump 32 and the negative pressure valve assembly 31 are working, the external water source sequentially enters the external water circuit 34, the first water pipe 331, the negative pressure valve assembly 31, the second water pipe 332, the water pump 32, the third water pipe 333 and the steam generating element 2, thereby realizing water supply to the steam generating element 2.

[0044] Therefore, through the above arrangement, the water can flow in sequence and in an orderly manner, and through the negative pressure effect of the negative pressure valve assembly 31, conditions can be provided for the water pump 32 to pump water, ensuring that the pumping process is carried out stably, and the pressure and flow rate of the water flow can be controlled to meet the needs of the steam generating element 2, and the negative pressure valve assembly 31 and the water pump 32 are arranged in sequence along the water flow direction, which helps to prevent safety problems caused by excessive water pressure.

[0045] In some embodiments, the length of the second water pipe 332 and the length of the third water pipe 333 are both less than the length of the first water pipe 331. Figure 3As shown, the first water pipe 331 is the longest, the second water pipe 332 and the third water pipe 333 are shorter, and the lengths of the two can be the same or different. This arrangement can provide greater flexibility and can adapt to the installation requirements and layout requirements of the first water pipe 331 at the front end. The longer pipeline can serve as a buffer, which can reduce a certain amount of water pressure during the flow of water. The second water pipe 332 and the third water pipe 333 are shorter, which can shorten the time for the water flow to reach the water pump 32 and the water inlet 21, so that the steam generating element 2 can respond to the change in the demand for water more quickly, and can reduce the pressure loss of the water flow in the pipeline, which is conducive to delivering high-pressure water to the steam generating element 2. The shorter pipeline can reduce the friction resistance of the water flow, thereby reducing energy consumption, and the overall structural layout is simpler and more compact, which is suitable for the integrated setting of more than 100 functions of the cooking device. And by setting pipelines of different lengths, its layout is reasonable, cost-saving, and easier to install and maintain.

[0046] Among them, Figure 3 As shown, the first water pipe 331 is a bent pipeline, which can meet the length requirement of the first water pipe 331 and realize the layout of the first water pipe 331 in a limited space, and the second water pipe 332 and the third water pipe 333 can be constructed as straight segment pipelines or as bent pipelines, so as to facilitate the connection with the pipelines between the negative pressure valve assembly 31, the water pump 32 and the steam generating element 2. This arrangement makes the layout of the water supply pipeline 3 more compact, saves more layout space of the water supply pipeline 3, and has various layout methods and high flexibility.

[0047] In some embodiments, the negative pressure valve assembly 31 includes a negative pressure valve 311 and a mounting bracket 312, the mounting bracket 312 is connected to the inner wall of the mounting cavity 11, the negative pressure valve 311 is installed on the mounting bracket 312 and is separated from the inner wall of the mounting cavity 11, and the negative pressure valve 311 is connected to the internal water channel 33.

[0048] Specifically, Figure 2 and Figure 3 As shown, the mounting bracket 312 can be made by bending sheet metal, and the mounting bracket 312 is formed with a mounting surface for installing the negative pressure valve 311, wherein the mounting bracket 312 is provided with a mounting hole, and the mounting bracket 312 can be detachably connected to the inner wall of the mounting cavity 11 by bolts and other connecting parts, and the negative pressure valve 311 is provided with a mounting hole, and correspondingly, the mounting surface is provided with a connecting hole, which is threadedly connected to the connecting hole at the mounting hole by bolts and other connecting parts, so that the negative pressure valve 311 and the mounting bracket 312 can be detachably connected, that is, the negative pressure valve 311 can be connected and fixed in the mounting cavity 11, and the connection method is simple and easy to disassemble and assemble.

[0049] Furthermore, by installing the bracket 312, the negative pressure valve 311 can be separated from the inner wall of the installation cavity 11, thereby avoiding direct contact between the negative pressure valve 311 and the inner wall of the installation cavity 11, and avoiding contact between the pipeline and the inner wall of the installation cavity 11, thereby avoiding water flow impacting the inner wall, reducing impact and noise, and the negative pressure valve 311 is connected to the internal water channel 33, which can achieve a pressure relief effect on the internal water channel 33 to stably maintain the water pressure.

[0050] Therefore, by arranging the negative pressure valve 311 to be installed on the mounting bracket 312, it can be ensured that the negative pressure valve 311 will not shift when the water pressure changes, and the installation stability of the negative pressure valve 311 can be guaranteed, thereby improving the working stability of the negative pressure valve 311 and maintaining the safe operation of the system. The mounting bracket 312 and the negative pressure valve 311 are integrated into one, which can be easily integrated into the system and is also convenient for disassembly and replacement.

[0051] In some embodiments, the water supply pipeline 3 further includes a pipe joint 35 , which is passed through the side wall of the equipment body 1 , and the internal water channel 33 and the external water channel 34 are respectively connected to the pipe joint 35 .

[0052] Specifically, the pipe joint 35 is a connecting element, which can be passed through the side wall of the equipment body 1. The two can be connected by means of threads, clamping, etc. The connection is reliable and stable, which prevents the pipe joint 35 from shaking and improves the reliability of the water connection. Among them, the pipe joint 35 can be constructed as a right-angle pipe joint 35 to adapt to different pipeline layout requirements, and the two ends of the pipe joint 35 are provided with an inlet end and a water outlet end. The internal waterway 33 and the external waterway 34 are both constructed to connect water pipes. During installation, the external waterway 34 is plugged and connected to the water inlet end, and the internal waterway 33 is plugged and connected to the water outlet end, so that the internal waterway 33 and the external waterway 34 can be connected to achieve water inflow.

[0053] Therefore, by setting the pipe joint 35, the internal water channel 33 and the external water channel 34 can be connected to the equipment body 1 through the pipe joint 35, and the pipe joint 35 has good sealing performance, which can prevent water leakage or external pollutants from entering the water supply pipeline 3, thereby ensuring the stability and safety of the water supply pipeline 3. The installation and maintenance of the pipe joint 35 are simpler and more convenient, and the operation flexibility is high. There are many types of pipe joints 35, and the adaptability is stronger.

[0054] In some embodiments, the steam outlet 22 is connected to a steam pipe, wherein the water supply pipeline 3 and the steam generating element 2 are located in the upper area of ​​the device body 1 , and the steam pipe extends downward to connect to the bottom of the cooking cavity 14 .

[0055] Specifically, Figure 1As shown, the water supply pipeline 3 and the steam generating element 2 are both arranged in the upper area of ​​the equipment body 1, the water supply pipeline 3 is connected with the water inlet 21 of the steam generating element 2, and the steam outlet 22 of the steam generating element 2 is connected with a steam transmission pipe, the steam transmission pipe is used to transmit steam, the steam transmission pipe extends from top to bottom, and the end of the steam transmission pipe away from the steam generating element 2 is connected with the bottom of the cooking cavity 14, so that an external water source can be introduced into the water supply pipeline 3 and the steam generating element 2 from above, after being heated in the steam generating element 2 to generate steam, the steam flows downward along the steam transmission pipe to the bottom area of ​​the cooking cavity 14, and the steam generating element 2 continuously transmits steam toward the cooking cavity 14, so as to continuously steam the food in the cooking cavity 14, thereby ensuring the continuity and cooking effect of cooking.

[0056] Therefore, by setting a steam supply pipe extending to the bottom of the cooking cavity 14, the steam can be evenly distributed at the bottom of the cooking cavity 14, thereby achieving a more consistent heating effect, and the overall structure of the water supply pipeline 3 and the steam generating element 2 occupies a smaller space and has a more compact layout, and will not occupy too much space in the installation cavity 11, which is conducive to the integrated setting of multiple functions of the cooking device 100.

[0057] In some embodiments, the device body 1 includes a rear shell 12 and a front door panel 13 , the front door panel 13 can be installed on the front side of the rear shell 12 to open or close the cooking cavity 14 , and the steam generating element 2 and the water supply pipe 3 are both fixed to the rear shell 12 .

[0058] Specifically, Figure 1 and Figure 2 As shown, the device body 1 includes a front door panel 13 and a rear shell body 12, the front door panel 13 is located at the front side of the rear shell body 12, and the front door panel 13 can be installed on the device body 1 in an openable and closable manner. The user can open or close the cooking cavity 14 by operating the opening and closing of the front door panel 13, which is convenient for the user to access the cooking cavity 14 and put in and take out food, and the steam generating element 2 and the water supply pipeline 3 are detachably connected to the side of the rear shell body 12 close to the front door panel 13. When steaming food, the user opens the front door panel 13 and puts the food to be cooked into the cooking cavity 14, and the external water source enters the water supply pipeline 3 and the steam generating element 2 from one side of the rear shell body 12 to realize steam production, and then the steam is transported to the cooking cavity 14 to steam the food. After cooking, the front door panel 13 is opened again to take out the food.

[0059] Therefore, the steam generator 2 and the water supply pipe 3 are arranged at the rear shell 12, which can occupy a smaller space, and the steam generator 2 and the water supply pipe 3 are away from the user's operation area, which can reduce the risk of the user directly contacting these high-temperature or water-containing components during the cooking process, and the use is safer. In addition, hiding the steam generator 2 and the water supply pipe 3 in the rear shell 12 can make the external structure of the device body 1 simpler and neater.

[0060] In some embodiments, the cooking device 100 further includes a control module, which is electrically connected to the water pump 32 and the steam generating element 2 , and controls the water pump 32 and the steam generating element 2 to selectively turn on or off.

[0061] Specifically, the control module is electrically connected to the water pump 32 and the steam generator 2, and can control the working status of the water pump 32 and the steam generator 2. Different cooking requirements and corresponding preset programs are set in the control module. When food needs to be steamed, the control module will control the water pump 32 and the steam generator 2 to turn on, that is, water can be supplied to the steam generator 2 through the water supply pipe 3, and the steam generator 2 converts water into steam and transports steam toward the cooking chamber 14 to achieve steaming of food. After the food is steamed, the control module controls the water pump 32 and the steam generator 2 to turn off, and in other cooking modes, the control module controls the water pump 32 and the steam generator 2 to turn off, so that the cooking device 100 can selectively turn on different cooking modes, making the cooking device 100 more convenient to use.

[0062] Therefore, by setting up a control module, the water flow of the water pump 32 and the heating intensity of the steam generator 2 can be accurately adjusted to adapt to different cooking processes to improve cooking efficiency, and automatic operation can be achieved. By controlling the water pump 32 and the steam generator 2 to work selectively, energy waste can be reduced and energy efficiency can be improved.
