Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and more specifically, to a water tank, a water supply device, and a cooking utensil. Background Technology

[0002] A steam oven is a multi-functional cooking appliance that combines steaming, air frying, and baking. However, when steaming takes a long time and requires a lot of water, the water tank needs to be refilled repeatedly to complete the process. The water tank is usually located behind the door assembly at the bottom of the machine. Before use, you need to open the door or pull out the water tank assembly to check if there is enough water for cooking. If the water tank indicates that it is low on water, you need to open the door or pull out the water tank to add water, which will stop the cooking process.

[0003] CN120052751A discloses an oven and a steam oven. The steam oven includes an oven, a steam generator, and a water tank. The water tank is detachably mounted on the side wall of the oven body. The steam generator is located in a second cavity and has a water inlet communicating with the water tank and a steam outlet communicating with the first cavity. Because the water tank is externally mounted, water can be added to the tank at any time when the water level is low, without stopping cooking or removing the water tank. However, in the above solution, water from the steam generator may flow back into the water tank, causing contamination of the water in the tank. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where water in a steam generator may flow back into the water tank, causing contamination of the water in the tank. This invention provides a water tank, a water supply device, and a cooking appliance that can prevent water outside the water tank from flowing back into the water tank.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A water tank is provided, including a tank body and a cover. The tank body has an inlet at the top and an outlet at the bottom. The cover is installed on the inlet, and a one-way valve is installed in the outlet.

[0006] The water tank of this utility model is installed on cooking appliances or other equipment that requires water supply. The water outlet is connected to the water supply device of the equipment. The cover is removed, and water is injected into the water tank through the water inlet. The cover is then installed to prevent dust, debris, and other external objects from entering the water tank. Under the action of gravity, the water in the water tank flows into the water supply device through the one-way valve and the water outlet. The one-way valve can prevent water outside the water tank from flowing back into the water tank through the water outlet.

[0007] Furthermore, the one-way valve includes a valve core, an elastic element, and a first sealing ring. The valve core is slidably disposed within the one-way valve, and the first sealing ring is fixed to the valve core. The first sealing ring is located above the water outlet and abuts against the bottom of the inner wall of the water tank body. The valve core is provided with a limiting part. One end of the elastic element abuts against the bottom of the water tank body, and the other end abuts against the limiting part. When water needs to be released from the tank, the valve core moves upward, causing the first sealing ring and the limiting part to move upward. The distance between the limiting part and the bottom of the water tank body shortens, and the limiting part presses against the elastic element at the bottom of the water tank body. When the first sealing ring moves upward, it disengages from the water tank body, the seal fails, and water in the water tank body flows out of the tank through the water outlet.

[0008] Furthermore, a guide tube is provided at the bottom of the water tank body, and the valve core and the elastic element are inserted into the guide tube. The guide tube can make the relative movement between the valve core and the water tank more stable.

[0009] Furthermore, a first grip is provided on the side wall of the water tank body. The first grip is a groove formed by the side wall of the water tank body recessing into the interior of the water tank body. The first grip allows the user to grasp it, making it convenient for the user to lift or move the water tank. The design of the first grip makes the handling and operation of the water tank more convenient and labor-saving, improving the user experience. The first grip is a groove integrally formed with the water tank, which not only meets the user's gripping needs but also prevents the first grip from breaking due to the excessive weight of the water tank after filling with water, while also making the appearance of the water tank more concise.

[0010] Furthermore, the outer wall of the water tank body is provided with a downward-facing hook groove, and the inner side wall of the hook groove is provided with multiple first locking ribs. When installing the water tank, align the hook groove on the water tank body with the hook on a cooking appliance or other device that requires water supply, and insert the hook into the hook groove. The first locking ribs reduce the gap between the two inner side walls of the hook groove. The first locking ribs and the inner side wall of the hook groove opposite to the first locking ribs together restrict the position of the hook, reduce the wobbling space of the hook, and prevent the water tank from falling off. The connection method of the hook groove and the hook is simple and reliable, which makes it easy for users to quickly install and remove the water tank, while ensuring that the water tank will not easily fall off during use.

[0011] Furthermore, the first locking rib is provided with a first guide slope facing the hook groove. When installing the water tank, the hook is inserted into the hook groove, and the first guide slope of the first locking rib acts as a guide, making it easier for the hook to be inserted deep into the hook groove. Therefore, while maintaining the ease of installation of the water tank body, the minimum distance between the first locking rib and the side wall of the hook groove opposite it can be reduced, thus improving the stability of the installation. The setting of the first guide slope makes the installation of the water tank smoother, and the stability after installation is higher, making it less likely to shake or fall off.

[0012] A water supply device is provided, including a connecting seat, a water supply pipe, and a water tank as described above. The connecting seat has a water receiving groove, and the bottom of the water receiving groove has a boss and a water inlet. The boss abuts against the bottom of the valve core, and the water inlet communicates with the water supply pipe. The water tank body is installed above the connecting seat. By reasonably designing the distance between the water tank body and the connecting seat, the boss of the connecting seat can lift the valve core, causing the valve core to move upward against the elastic force of the elastic element. The first sealing ring moves upward with the valve core, disengaging from the bottom surface of the inner wall of the water tank body. The one-way valve opens, and water in the water tank body flows out of the water tank body through the outlet under gravity, enters the water receiving groove, and then flows into the water supply pipe through the water inlet. When the water tank body is removed, the elastic element pushes the limiting part downward. The valve core moves downwards, causing the first sealing ring to move downwards as well. This allows the first sealing ring to come into contact with the bottom surface of the inner wall of the water tank body, blocking the outlet and achieving a seal. The one-way valve closes, preventing water from flowing out of the outlet. When the water tank body is installed and removed, the one-way valve can automatically close and open, preventing leakage. The operation is simple and convenient. The water collection tank can collect water that overflows or spills during the installation or removal of the water tank. The overflowing or spilled water can flow into the water supply pipe through the water collection port, preventing it from flowing around and facilitating cleaning.

[0013] Furthermore, it also includes a water storage base and a second sealing ring. The water storage base has an upward-opening water tank, the top opening of which is located below the water inlet and connected to the water supply pipe. One end of the second sealing ring abuts against the water storage base, and the other end abuts against the connecting seat. The water storage tank acts as a buffer, allowing water flowing from the outlet of the water tank body to first flow into the water storage tank for temporary storage. When subsequent components (such as a steam generator) need water, the water in the storage tank flows into the water supply pipe, preventing water supply interruptions caused by unstable water output from the water tank body and avoiding disruption to the normal operation of subsequent components due to unstable water supply. The second sealing ring fills the gap between the connecting seat and the water storage base to prevent leakage.

[0014] Furthermore, it also includes an upward-opening water receiving base. The connecting seat, the water storage base, and the water supply pipe are installed in the water receiving base. A downward-extending baffle is provided on the bottom edge of the water tank body. The top of the water receiving base abuts against the baffle. The water receiving base and the baffle isolate the one-way valve and the water inlet from the outside. The baffle cooperates with the water receiving base to prevent external debris and dust from entering the water storage tank through the water inlet, avoiding water pollution or blockage of the water supply pipe.

[0015] A cooking appliance is provided, comprising a housing, a steam generator, and a water supply device. The steam generator is installed inside the housing, and the water tank body is detachably installed on the outer wall of the housing. The side wall of the housing has mounting holes, and a water receiving base and a connecting seat are inserted into these mounting holes. A water supply pipe is connected to the steam generator. During installation, the connecting seat and water storage base are installed in the water receiving base, the water supply pipe is installed on the water storage base, and the water receiving base is inserted into the mounting holes on the side wall of the housing, connecting the water supply pipe to the steam generator. The water tank body is moved to align the one-way valve with the boss, and the water tank is installed on the side wall of the housing, completing the installation of the water supply device. At this time, the boss pushes the valve core of the one-way valve upwards, the limiting part moves upwards to compress the elastic element, the first sealing ring moves upwards and disengages from the water tank body, the seal fails, and water in the water tank body flows out through the outlet. Water flows into the water tank through the inlet. When the steam generator is working, the water stored in the water tank is fed into the steam generator through the water pipe to generate steam. If the water level in the tank is low during the steam generation process, the tank can be opened at any time and water can be added through the inlet since it is located outside the main unit. This does not require stopping the cooking process or removing the tank, making the operation simple and quick. At the same time, the tank is not limited by the internal space of the main unit, allowing for a larger capacity and reducing the frequency of water addition.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The water tank of this utility model has the following features: 1. A one-way valve is provided at the bottom of the water tank to prevent water outside the tank from flowing back into the tank body through the outlet; 2.

[0021] Example 1 like Figures 1 to 6 The first embodiment of the water tank of this utility model is shown, which includes a water tank body 2 and a cover 27. The top of the water tank body 2 is provided with a water inlet 25, and the bottom of the water tank body 2 is provided with a water outlet 26. The cover 27 is installed on the water inlet 25, and a one-way valve 28 is installed in the water outlet 26.

[0022] The water tank of this utility model is installed on cooking appliances or other equipment that requires water supply. The outlet 26 is connected to the water supply device of the equipment. The cover 27 is removed, and water is injected into the water tank body 2 through the inlet 25. Under the action of gravity, the water in the water tank body 2 flows into the water supply device through the one-way valve 28 and the outlet 26. The one-way valve 28 can prevent the water in the water supply device from flowing back into the water tank body 2 through the outlet 26.

[0023] like Figure 2 As shown, the one-way valve 28 includes a valve core 281, an elastic element 282, and a first sealing ring 283. The valve core 281 is slidably disposed in the one-way valve 28, and the first sealing ring 283 is fixed on the valve core 281. The first sealing ring 283 is located above the outlet 26 and abuts against the bottom of the inner wall of the water tank body 2. The valve core 281 is provided with a limiting part 2811. One end of the elastic element 282 abuts against the bottom of the water tank body 2, and the other end abuts against the limiting part 2811. When water needs to be discharged from the water tank, the valve core 281 moves upward, causing the first sealing ring 283 and the limiting part 2811 to move upward. The distance between the limiting part 2811 and the bottom of the water tank body 2 shortens, and the limiting part 2811 and the bottom of the water tank body 2 press against the elastic element 282. When the first sealing ring 283 moves upward, it loses contact with the water tank body 2, the seal fails, and the water in the water tank body 2 flows out of the water tank through the outlet 26. In this embodiment, the elastic element 282 is a spring.

[0024] like Figure 2As shown, a guide tube 2110 is provided at the bottom of the water tank body 2, and the valve core 281 and the elastic element 282 are inserted into the guide tube 2110. The guide tube 2110 can make the relative movement between the valve core 281 and the water tank more stable.

[0025] In this embodiment, as Figure 6 As shown, the outer periphery of the cover 27 is provided with multiple vertically arranged second locking ribs 273. The bottom of each second locking rib 273 has a second guide slope. The multiple second locking ribs 273 on the outer periphery of the cover 27 are interference-fitted with the water inlet 25 of the water tank. When installing the cover 27, the second locking ribs 273 are pressed into the water inlet 25 by the guiding action of the second guide slope. The second locking ribs 273 press against the inner wall of the water inlet 25, achieving locking and completing the fixed installation of the cover 27. Eight locking ribs 273 are provided; the cover body 27 includes an upper cover 271 and a lower cover 272. The lower cover 272 is fixedly installed on the bottom surface of the upper cover 271. The second locking rib 273 is installed on the outer periphery of the lower cover 272. The bottom surface of the upper cover 271 abuts against the top of the water tank; four upwardly extending sub-rings 29 are provided on the bottom surface of the inner wall of the water tank body 2 to limit the position of the first sealing ring 283. The four sub-rings 29 are symmetrically distributed with respect to the axis of the water outlet 26. The first sealing ring 283 is located between the four sub-rings 29.

[0026] like Figure 3 As shown, a first grip portion 21 is provided on the side wall of the water tank body 2. The first grip portion 21 is a groove formed by the side wall of the water tank body 2 recessed into the interior of the water tank body 2. The first grip portion 21 can be gripped by the user, making it convenient for the user to lift or move the water tank. The design of the first grip portion 21 makes the handling and operation of the water tank more convenient and labor-saving, improving the user experience. The first grip portion 21 is a groove integrally formed with the water tank, which not only meets the user's gripping needs, but also prevents the first grip portion 21 from breaking due to the excessive weight of the water tank after filling with water, and at the same time makes the appearance of the water tank more concise.

[0027] like Figure 3 and Figure 4 As shown, a second gripping part 22 is provided on the side wall adjacent to the side wall of the water tank body 2 where the first gripping part 21 is located. The second gripping part 22 is a groove formed by the side wall of the water tank body 2 recessed into the water tank body 2. When the user grips the water tank body 2, he can put his thumb into the second gripping part 22 and put the other four fingers into the first gripping part 21. The five fingers work together to grip the water tank, which conforms to the gripping habits of human hands and makes the grip on the water tank more stable.

[0028] like Figure 4 and Figure 5As shown, the outer wall of the water tank body 2 is provided with a downward-facing hook groove 24, and the inner side wall of the hook groove 24 is provided with multiple first locking ribs 241. When installing the water tank, align the hook groove 24 on the water tank body 2 with the hook 111 on the cooking appliance or other equipment that requires water supply, and insert the hook 111 into the hook groove 24. The first locking ribs 241 reduce the gap between the two inner side walls of the hook groove 24. The first locking ribs 241 and the inner side wall of the hook groove 24 opposite to the first locking ribs 241 together restrict the position of the hook 111, reduce the wobbling space of the hook 111, and prevent the water tank from falling off. The connection method between the hook groove 24 and the hook 111 is simple and reliable, which makes it easy for users to quickly install and remove the water tank, while ensuring that the water tank will not easily fall off during use.

[0029] like Figure 5 As shown, the first locking rib 241 has a first guide slope with an opening facing the hook groove 24. When installing the water tank, the hook 111 is inserted into the hook groove 24. The first guide slope of the first locking rib 241 acts as a guide, making it easier for the hook 111 to be inserted into the depth of the hook groove 24. Therefore, while maintaining the ease of installation of the water tank body 2, the minimum distance between the first locking rib 241 and the side wall of the hook groove 24 directly opposite it can be reduced, thus improving the stability of the installation. The setting of the first guide slope makes the installation of the water tank smoother and the stability after installation higher, making it less likely to shake or fall off.

[0030] The working principle of the water tank in this embodiment is as follows: When in use, remove the cover 27, inject sufficient water into the water tank body 2 through the water inlet 25 according to water demand, install the cover 27 to prevent external dust, debris, etc. from entering the water tank body 2, hold the first grip part 21 and the second grip part 22 by hand, move the water tank body 2 so that the hook groove 24 of the water tank body 2 is aligned with the hook 111 of cooking utensils or other equipment that requires water supply, press down the water tank body 2 so that the hook groove 24 is hooked on the hook 111, and after the hook 111 contacts the first locking rib 241, it moves along the first guide slope. The hook groove 24 moves deeper, causing the hook 111 to engage with the hook groove 24; this connects the outlet 26 to the water supply device of the equipment. When water needs to be drained from the tank, the valve core 281 moves upward along the guide tube 2110, causing the first sealing ring 283 and the limiting part 2811 to move upward. The distance between the limiting part 2811 and the bottom of the tank body 2 is shortened, and the limiting part 2811 and the bottom of the tank body 2 press against the elastic element 282. When the first sealing ring 283 moves upward, it loses contact with the tank body 2, the seal fails, and the water in the tank body 2 flows out of the tank through the outlet 26 under the action of gravity.

[0031] Example 2 This embodiment is the first embodiment of the water supply device of this utility model, such as... Figure 7As shown, the system includes a connecting seat 3, a water supply pipe 6, and the water tank described in Embodiment 1. The connecting seat 3 has a water receiving groove 31, and the bottom of the water receiving groove 31 has a boss 32 and a water inlet 33. The boss 32 abuts against the bottom of the valve core 281, and the water inlet 33 is connected to the water supply pipe 6. The water tank body 2 is installed above the connecting seat 3. By reasonably designing the distance between the water tank body 2 and the connecting seat 3, the boss 32 of the connecting seat 3 can lift the valve core 281, causing the valve core 281 to move upward against the elastic force of the elastic element 282. The first sealing ring 283 moves upward with the valve core 281, and the first sealing ring 283 disengages from the bottom surface of the inner wall of the water tank body 2. The one-way valve 28 opens, and the water in the water tank body 2 flows out of the water tank body 2 through the outlet 26 under the action of gravity, enters the water receiving groove 31, and then flows into the water supply pipe 6 through the water inlet 33. When the water tank body 2 is removed, the elastic element 282 pushes the limit The position part 2811 moves downward, driving the entire valve core 281 downward, which in turn drives the first sealing ring 283 downward, so that the first sealing ring 283 abuts against the bottom surface of the inner wall of the water tank body 2, blocking the outlet 26 and achieving a seal. The one-way valve 28 closes to prevent water from flowing out of the outlet 26. When the water tank body 2 is installed and removed, the one-way valve 28 can automatically close and open, avoiding water leakage. The operation is simple and convenient. The water receiving tank 31 can collect water that overflows or spills during the installation or removal of the water tank. The overflowing or spilled water can flow into the water supply pipe 6 through the water receiving port 33, preventing it from flowing around and facilitating cleaning.

[0032] like Figure 7 As shown, it also includes a water storage base 4 and a second sealing ring 5. The water storage base 4 has a water storage tank 41 with an upward opening. The top opening of the water storage tank 41 is located below the water inlet 33 and is connected to the water supply pipe 6. One end of the second sealing ring 5 abuts against the water storage base 4, and the other end abuts against the connecting seat 3. The water storage tank 41 can play a buffering role. The water flowing out of the water outlet 26 of the water tank body 2 first flows into the water storage tank 41 for temporary storage. When subsequent components (such as the steam generator 16) need to supply water, the water in the water storage tank 41 flows into the water supply pipe 6, avoiding the problem of water supply interruption caused by the instantaneous fluctuation of the water supply of the water tank body 2, and avoiding the impact of unstable water supply on the normal operation of subsequent components. The second sealing ring 5 fills the gap between the connecting seat 3 and the water storage base 4 to prevent water leakage.

[0033] It also includes an upward-opening water receiving base 7. The connecting seat 3, water storage seat 4, and water supply pipe 6 are installed in the water receiving base 7. A downward-extending baffle 210 is provided on the bottom edge of the water tank body 2. The top of the water receiving base 7 abuts against the baffle 210. The water receiving base 7 and the baffle 210 isolate the one-way valve 28 and the water inlet 33 from the outside. The baffle 210 cooperates with the water receiving base 7 to prevent external debris and dust from entering the water storage tank 41 through the water inlet 33, thus avoiding water pollution or blockage of the water supply pipe 6.

[0034] The working principle of the water supply device in this embodiment is as follows: The water storage base 4 and the water supply pipe 6 are installed in the water receiving base 7. The second sealing ring 5 is placed on top of the water storage base 4. The connecting seat 3 is installed in the water receiving base 7, so that the bottom of the connecting seat 3 abuts against the second sealing ring 5, achieving a seal at the junction of the connecting seat 3 and the water storage base 4. The water supply pipe 6 is connected to the component requiring water supply. The water tank body 2 is installed above the connecting seat 3, so that the protrusion 32 of the connecting seat 3 can push up the valve core 281, causing the valve core 281 to move upward against the elastic force of the elastic element 282. The first sealing ring 283 moves upward with the valve core 281, and the first sealing ring 283 disengages from the bottom surface of the inner wall of the water tank body 2, opening the one-way valve 28. When the water tank body 2 is opened, the water in the water tank body 2 flows out of the water tank body 2 through the outlet 26 under the action of gravity, enters the water receiving tank 31, and then flows into the water storage tank 41 on the water storage base 4 through the water receiving port 33. When the subsequent components (such as the steam generator 16) need to supply water, the water in the water storage tank 41 flows into the water supply pipe 6, and then enters the subsequent components through the water supply pipe 6. When the water tank body 2 is removed, the elastic element 282 pushes the limiting part 2811 to move downward, which drives the entire valve core 281 to move downward, and drives the first sealing ring 283 to move downward, so that the first sealing ring 283 abuts against the bottom surface of the inner wall of the water tank body 2, blocking the outlet 26 and achieving a seal. The one-way valve 28 closes to prevent water from flowing out of the outlet 26.

[0035] Example 3 This embodiment is the first embodiment of the cooking appliance of this utility model, such as... Figures 8 to 10As shown, a cooking appliance is provided, including a housing 1, a steam generator 16, and a water supply device as described in Embodiment 2. The steam generator 16 is installed inside the housing 1, and the water tank body 2 is detachably installed on the outer wall of the housing 1. The side wall of the housing 1 is provided with mounting holes, and the water receiving base 7 and the connecting seat 3 are inserted into the mounting holes. The water supply pipe 6 is connected to the steam generator 16. During installation, the connecting seat 3 and the water storage seat 4 are installed in the water receiving base 7, the water supply pipe 6 is installed on the water storage seat 4, and the water receiving base 7 is inserted into the mounting hole located on the side wall of the tank body 1, so that the water supply pipe 6 is connected to the steam generator 16. The water tank body 2 is moved so that the one-way valve 28 is aligned with the boss 32, and the water tank is installed on the side wall of the tank body 1, completing the installation of the water supply device. At this time, the boss 32 pushes the valve core 281 of the one-way valve 28 upward, the limiting part 2811 moves upward to compress the elastic element 282, the first sealing ring 283 moves upward and disengages from the water tank body 2, the seal fails, and the water tank body 2... Water flows out through outlet 26 and into water tank 31 through inlet 33. When steam generator 16 is working, water stored in water tank 31 is fed into steam generator 16 through water pipe 6 to generate steam. If the water level in the tank is low during steam generation, the tank can be opened at any time through inlet 25 to add water since the tank is located outside the body 1. This does not require stopping cooking or removing the tank, making the operation simple and quick. At the same time, the tank is not limited by the internal space of body 1, allowing for a larger capacity and reducing the frequency of water addition.

[0036] In this embodiment, as Figure 10 As shown, it also includes a door 12, which is rotatably connected to the box body 1. Specifically, the door 12 is rotatably connected to the box body 1 via a hinge, and when the door 12 is closed, it separates the interior and exterior of the box body 1; as shown Figure 8 As shown, mounting racks 13 are provided on two opposite inner side walls of the box 1, and steaming trays 14 for holding food are installed on the mounting racks 13.

[0037] The cooking appliance can be a steam oven, steam oven, or other appliance that requires the steam generator 16 to produce steam. In this embodiment, the cooking appliance is a steam oven. Figure 9As shown, the cooking appliance also includes a fan 17 and a first heating device 18. A partition 15 is installed inside the housing 1, dividing the inner cavity of the housing 1 into a first cavity and a second cavity. A mounting rack 13 and a steaming tray 14 are disposed in the first cavity. A steam generator 16, the first heating device 18, and the fan 17 are disposed in the second cavity. The first cavity has an air outlet and an air inlet. The fan 17 blows air through the first heating device 18, generating hot air, which enters the first cavity through the air outlet to bake the food on the steaming tray 14, and then flows back to the second cavity through the air inlet. The steam generator 16 has a water supply port connected to the water pipe 6 and a steam outlet connected to the first cavity. A water pump is installed on the device 16 to prevent insufficient water level in the water tank from preventing steam from being delivered to the steam outlet. Hot air, together with the steam generated by the steam generator 16, cooks the food and enhances the cooking effect. An evaporation plate 19 is located at the center of the bottom surface of the inner wall of the box 1. The height of the bottom surface of the inner wall of the box 1 gradually decreases from the edge to the evaporation plate 19, so that the water after steam condensation flows into the evaporation plate 19 under the action of gravity. A second heating device is installed at the bottom of the evaporation plate 19. The second heating device can make the condensate in the evaporation plate 19 evaporate into high-temperature steam again, realize the recycling of internal steam, increase the amount of steam during the baking process, and facilitate cleaning. Both the first heating device 18 and the second heating device are heating tubes.

[0038] In this embodiment, as Figure 10 As shown, a fastener 11 is provided on the outer wall of the tank body 1. The fastener 11 is connected to the outer wall of the tank body 1 by screws. The fastener 11 has an upwardly extending hook 111, which is inserted into the hook groove 24 on the outer wall of the water tank body 2. When installing the water tank, the fastener 11 is installed on the side wall of the tank body 1 by screws, and the hook 111 on the fastener 11 is inserted into the hook groove 24. The outer wall of the water tank body 2 is provided with an installation groove 23 for accommodating the fastener 11 and the hook 111, so that the water tank is closer to the tank body 1 after installation, improving space utilization. The hook groove 24 is located at the top of the inner wall of the installation groove 23.

[0039] The working principle of the cooking appliance in this embodiment is as follows: During installation, the connecting seat 3 and the water storage seat 4 are installed in the water receiving base 7, the water supply pipe 6 is installed on the water storage seat 4, and the water receiving base 7 is inserted into the mounting hole located on the side wall of the tank body 1, so that the water supply pipe 6 is connected to the steam generator 16. The water tank body 2 is moved so that the one-way valve 28 is aligned with the boss 32, and the hook groove 24 of the water tank is engaged with the hook 111 on the side wall of the tank body 1, thus completing the installation of the water supply device. At this time, the boss 32 pushes the valve core 281 of the one-way valve 28 upward, the limiting part 2811 moves upward to compress the elastic member 282, the first sealing ring 283 moves upward and disengages from the water tank body 2, the seal fails, the one-way valve 28 opens, and the water in the water tank body 2 flows out through the water outlet 26 and into the water receiving trough 3 through the water inlet 33. In step 1, the steam generator 16, the first heating device 18, and the fan 17 start working. Water stored in the water tank 31 is input into the steam generator 16 through the water pipe 6 to generate steam. The fan 17 blows air through the first heating device 18 to generate hot air. The steam and hot air pass through the partition 15 and enter the first chamber to cook the food on the steaming tray 14. After the steam condenses into water, it is collected in the evaporation tray 19 by gravity. The second heating device evaporates the condensate into high-temperature steam, increasing the amount of steam and improving the cooking effect. When the water in the water tank is found to be insufficient during the steam generator's steam generation process, since the water tank is located outside the body 1, the cover 27 can be opened at any time to add water to the water tank through the water inlet 25 without stopping the cooking process or removing the water tank.
