Description

Technical Field

[0001] This application belongs to the field of kitchen appliance technology, specifically relating to a cooking appliance that can automatically fill and drain water. Background Technology

[0002] Current cooking appliances, such as rice cookers, typically require manually placing the ingredients into the inner pot before cooking. Taking rice as an example, this manual method can lead to variations in the cooked rice due to inaccurate rice-to-water ratios. To achieve a more precise rice-to-water ratio, an automatic water-filling system can be selected. This system usually involves connecting a water tank to the cooking chamber via a water pipe to meet diverse cooking needs, such as making low-sugar rice.

[0003] However, there are certain technical obstacles to injecting water into the cooking cavity via a pipe. The cooking cavity is generally formed by an inner pot and an inner lid; one method involves pipes passing through the inner pot, while the other involves pipes passing through the inner lid. Piping through the inner pot requires perforating the side wall of the inner pot, which significantly impacts the manufacturing process and product reliability. Piping through the inner lid may affect the opening and closing of the lid, and after water is injected into the cooking cavity through the inner lid, the injected water may not undergo sufficient heat exchange before draining out, affecting the cooking effect. Therefore, this method needs improvement. Utility Model Content

[0004] This application provides a cooking appliance that can automatically fill and drain water, which can meet diverse cooking needs and ensure sufficient heat exchange after water supply.

[0005] The technical solution adopted in this application is as follows:

[0006] An automatic water filling and draining cooking appliance includes a pot body, a pot lid, and a water tank. The pot lid and the pot body are hinged together. The pot body has an inner liner. The pot lid covers the inner liner to form a cooking cavity. The pot lid has a water inlet. The bottom of the inner liner has a drain valve. The water inlet and the drain valve are offset in the vertical direction.

[0007] Furthermore, the water supply outlet is located on the side near the hinge.

[0008] Furthermore, the drain valve is located at the center of the inner liner.

[0009] Furthermore, the pot lid is also equipped with a temperature measuring rod, which is located at the center of the pot lid.

[0010] Furthermore, the pot lid includes an inner lid, on which a water inlet is provided, and a water supply end is provided at the water inlet, through which a water pipe passes to form a water supply end; or the pot lid is provided with a water pipe connector for connecting a water pipe, through which the water pipe connector passes to form a water supply end.

[0011] Furthermore, the pot lid is equipped with a steam valve, and the water tank is connected to the steam valve through a water pipe to supply water to the cooking chamber.

[0012] Furthermore, the pot lid includes an inner lid and a liner, with a water-filling buffer cavity provided between the inner lid and the liner. The inner lid has a through hole that connects to the cooking cavity. The water tank supplies water to the water-filling buffer cavity through a water pipe, and the liquid in the water-filling buffer cavity is supplied to the cooking cavity through the through hole.

[0013] Furthermore, the horizontal distance between the water supply port and the drain valve is greater than 10 millimeters.

[0014] Furthermore, the pot is equipped with a water pump, one end of which is connected to a water tank and the other end is connected to a water pipe to automatically inject water into the cooking cavity.

[0015] Furthermore, a water receiving box is provided below the inner liner, and the water receiving box is configured corresponding to the drain valve.

[0016] This application has the following beneficial effects:

[0017] 1. Water is automatically supplied to the cooking cavity via a water tank, allowing for water replenishment during cooking to meet diverse cooking needs. A drain valve at the bottom of the inner pot allows water to be drained when necessary. The automatic water filling and draining system enables multiple rinses of food within the cooking cavity. The water inlet and drain valve are vertically offset, ensuring that the injected water undergoes sufficient heat exchange within the cooking cavity before being discharged.

[0018] 2. The water inlet is located on the side near the hinge. This reduces the length of the water pipe extending onto the pot lid, avoiding taking up too much space on the lid.

[0019] 3. The drain valve is located in the center of the inner tank. This allows for the rapid drainage of water from the inner tank when drainage is needed, preventing localized dampness. Attached Figure Description

[0040] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0041] This application discloses a cooking appliance with automatic water filling and drainage, comprising a pot body, a lid, and a water tank. The lid and pot body are hinged together, and the pot body has an inner liner. The lid closes the inner liner to form a cooking cavity. The key feature is that the lid has a water inlet, and the bottom of the inner liner has a drain valve, with the water inlet and drain valve being offset. This offset arrangement of the water inlet and drain valve allows for sufficient heat exchange before water is drained after filling. Specific embodiments will be described below.

[0042] Example 1

[0043] Reference Figures 1-5 The cooking appliance of this embodiment includes a pot body 1 and a lid 2. The pot body 1 has an inner pot 3, and the lid 2 covers the inner pot 3 to form a cooking cavity. The cooking appliance also includes a water tank 4, which supplies water to the cooking cavity via a water pipe 5. During operation, food is placed inside the cooking cavity. When water is needed for cooking, water from the water tank 4 is supplied to the cooking cavity via the water pipe 5. Specific usage scenarios include cooking rice or low-sugar rice, providing water at specific stages to meet diverse cooking needs.

[0044] To achieve automatic water supply, a water pump 41 can be installed inside the pot. One end of the water pump is connected to the water tank 4, and the other end is connected to a water pipe to automatically inject water into the cooking cavity.

[0045] As a cooking appliance in this embodiment, during cooking, the ingredients to be cooked can be placed in the inner pot 3 first. The water tank 4 stores purified water for cooking. Taking the cooking of low-sugar rice as an example, an appropriate amount of rice and water can be placed in the inner pot first (water can also be omitted if necessary). When cooking reaches a certain stage, water can be supplied to the cooking chamber through the water tank 4. For example, during the cooking process, the water containing dissolved sugar in the inner pot can be drained, and then water can be supplied again to achieve the final goal of forming low-sugar rice. The draining method can be through a one-way valve set at the bottom of the inner pot, or it can be sucked out through a pipe. A water collection box 6 can also be set up to collect the drained wastewater as needed. Since automatic water supply can be realized, water can be supplied and drained multiple times as needed to reduce the sugar content of the rice. If a one-way valve is set, the one-way valve has a filter structure to prevent rice from being discharged during drainage.

[0046] In this embodiment, refer to Figure 4 The pot lid 2 includes an inner lid 21 and a liner 22. The inner lid 21 is provided with a water inlet 211 and a water supply end 212. The pot lid 2 is provided with a temperature measuring rod 23 that extends into the cooking cavity. The downward extension distance of the temperature measuring rod 23 is greater than the downward extension distance of the water supply end 212.

[0047] With this configuration, the temperature measuring rod 23 can sense the temperature inside the cooking cavity more promptly. For example, when boiling, the foam will first come into contact with the temperature measuring rod 23 and then with the water supply end 212. After sensing that the temperature inside the cooking cavity has reached the boiling temperature threshold, the temperature measuring rod 23 can reduce or even stop heating in time to reduce the continuous rise of foam during boiling and its entry into the water supply end, which would cause the water supply end 212 to be contaminated by foam.

[0048] Furthermore, this design facilitates the removal and installation of the inner cover 21. Because the outer diameter of the temperature measuring rod 23 is significantly smaller than the outer diameter of the water supply end 212, the inner cover 21 is provided with mounting ports for the temperature measuring rod 23 and for the water supply end 212 to pass through. By combining the slender temperature measuring rod 23 with the short and thick water supply end, the inner cover 21 can be removed and installed without interference, which would affect the efficiency of removing and installing the inner cover. It also has a certain positioning function when installing the inner cover 21.

[0049] In this embodiment, refer to Figure 3 and Figure 4 The pot lid 2 is equipped with a water pipe connector, which passes through the water supply port 211 to form a water supply end 212. A water pipe connector is also provided on the liner 22; the upper end of the connector is used to connect to the water pipe 5, and the lower end passes through the water supply port 211 of the inner cover 21 to form a water supply end, supplying water to the cooking cavity. An inverted buckle structure can be provided at the upper end of the water pipe connector to facilitate water pipe installation and prevent the water pipe from coming loose. The water pipe can also be secured with cable ties after connection. In other embodiments, the water pipe may pass through the water supply port 211 to form the water supply end.

[0050] In this embodiment, a sealing ring is provided at the water supply port 211 to seal the gap between the water supply port 211 and the water supply end 212. The sealing ring may be provided on the outer periphery of the water supply port 211 to seal the gap between the two when the water supply end passes through the water supply port 211.

[0051] In this embodiment, refer to Figure 2 and Figure 3 The lid 2 is hinged to the pot body 1, and the water inlet 211 is located on the inner lid near the hinge. Because the lid 2 is hinged to the pot body 1, the water pipe can extend from the pot body to the lid 2 through the rear hinge. The location of the water inlet 211 on the inner lid near the hinge reduces the extension length of the water pipe on the lid, avoiding excessive space occupation. The lid 2 is rotatably connected to the pot body 1 via the hinge. During the opening and closing of the lid, the lid 2 rotates continuously, and the water pipe 5 rotates along with the lid 2. The water inlet 211 is located on the lid near the hinge, and the water pipe 5 is also mainly distributed on the lid 2 near the hinge, reducing the impact on the lifespan of the water pipe during opening and closing.

[0052] In this embodiment, refer to Figure 5The temperature measuring rod 23 is located at the center of the inner cover, and the horizontal distance between the water inlet 211 and the temperature measuring rod is greater than 10 mm. The center location of the temperature measuring rod 23 allows for more accurate measurement of the temperature inside the cooking cavity, while the greater than 10 mm horizontal distance between the water inlet 211 and the temperature measuring rod 23 reduces the impact of the water inlet 211 on the accuracy of the temperature measurement. Because the water inlet is inevitably at a lower temperature during the process of cold water entering, the distance between it and the temperature measuring rod 23 allows the temperature measuring rod 23 to more objectively detect the temperature inside the cooking cavity.

[0053] In other embodiments, the inner cover 21 is provided with a steam inlet 24, and the steam inlet 24, the temperature measuring rod, and the water supply port 211 are located on the same straight line. Therefore, the inner cover has three through holes on the same straight line, which is more aesthetically pleasing.

[0054] In this embodiment, refer to Figure 2 and Figure 3 The inner cover 21 is equipped with a steam valve 25, which has a steam outlet 28. Steam generated in the cooking cavity enters the steam valve through the steam inlet 24 and is discharged to the outside through the steam outlet 28. By setting the steam valve 25, foam overflow can be reduced, steam can flow in an orderly manner, and a certain amount of condensate can be formed and flow back into the cooking cavity.

[0055] In this embodiment, a spray structure is provided on the water supply end to spray water into the cooking cavity. Spraying water into the cooking cavity through the spray structure makes the water intake more even and reduces impact on the food. Taking cooking rice as an example, the spray structure prevents water from affecting the flatness of the rice surface. The spray structure can be composed of multiple angled holes at the water supply end, forming a spray pattern of water.

[0056] In other embodiments, the temperature measuring rod is also equipped with an anti-overflow probe, which extends downward a greater distance than the water pipe extends downward. During cooking, when foam is generated, it will first come into contact with the anti-overflow probe, thereby reducing the power or even stopping heating to prevent the foam from continuing to rise and entering the water pipe, causing contamination or blockage.

[0057] In this embodiment, a drain outlet is provided at the bottom of the inner pot, and a drain valve 31 is provided on the drain outlet. By providing the drain valve 31, the drain valve 31 can be opened when drainage is needed to drain the water in the inner pot. Because the cooking appliance of this embodiment can automatically fill water into the cooking cavity, the water in the cooking cavity will increase. By providing the drain valve, some water can be drained as needed to achieve a specific cooking purpose, such as draining rice water containing sugar. Specifically, the drain valve 31 can be opened or blocked by a movable seal, or by a movable push rod or magnetic drive.

[0058] In this embodiment, combined with Figure 2 and Figure 5 The water inlet 211 and drain valve 31 are vertically offset. That is, the water inlet 211 and drain valve 31 are not on the same vertical line. This arrangement allows for sufficient heat exchange after the water tank 4 supplies water to the cooking cavity before it is discharged through the drain valve 31. A more obvious and easily conceivable arrangement would be to center both the water inlet 211 and drain valve 31, placing them on the same vertical line. The problem with this is insufficient heat exchange between the water and the cooking cavity. The injected water does not have sufficient heat exchange with all the ingredients in the cooking cavity. For example, when cooking low-sugar rice, the water does not fully contact the rice in the cooking cavity before flowing away, resulting in poor low-sugar rice cooking.

[0059] Specifically, the horizontal distance between the water inlet 211 and the drain valve 31 is greater than 10 mm. That is, when one is centered, the other will be slightly off-center, with a certain horizontal distance, and this distance is greater than 10 mm, to ensure that there is as much heat exchange as possible after water is supplied.

[0060] In this embodiment, refer to Figure 2 The drain valve 31 is located in the center of the inner tank. The water inlet 211 is slightly off-center. The centrally located drain valve 31 allows water to be drained from the inner tank as quickly as possible when drainage is needed, preventing localized dampness.

[0061] In this embodiment, refer to Figure 2 A water collection box 6 is located below the inner pot 3, and the water collection box 6 is corresponding to the drain valve. When the inner pot 3 needs to drain, the water discharge from the inner pot can be collected through the water collection box 6. The water collection box 6 can be set by pulling it out, and the user can pour out the wastewater in the water collection box 6 after cooking.

[0062] In this embodiment, the water inlet is provided through a water inlet 211 on the inner cover 21, with a water supply end 212 at the water inlet 211 supplying water to the cooking cavity. The water supply end can be formed by a water pipe connector passing through the water inlet, or by a water pipe passing through the water inlet of the inner cover 21. Alternatively, the water pipe can be sealed to the water inlet 211 without extending through the inner cover 21 into the cooking cavity; in this case, the downward extension distance of the water supply end should be considered zero. Furthermore, the water pipe can supply water to the cooking cavity via other components; please refer to the embodiments described later.

[0063] Low-sugar rice cooking is just one example in this embodiment. Depending on actual cooking needs, other diverse cooking requirements can also be met by adding water. For example, adding a certain amount of water during the cooking of porridge or soup can prevent overflow.

[0064] Example 2

[0065] The main difference between this embodiment and Embodiment 1 lies in the water inlet method. In Embodiment 1, water is injected into the cooking cavity through the water supply end, while in this embodiment, water is mainly supplied into the cooking cavity through the water injection buffer chamber. For details, please refer to... Figures 6-8 A water-filling buffer chamber 213 is provided between the inner cover 21 and the liner 22. The inner cover 21 has a through hole that connects to the cooking chamber. The water tank 4 supplies water to the water-filling buffer chamber 213 through a water pipe, and the liquid in the water-filling buffer chamber 213 is supplied to the cooking chamber through the through hole.

[0066] By incorporating a water-filling buffer chamber 213, the flow rate of water supplied to the cooking chamber is slowed down, preventing direct water injection from impacting the food (such as rice) inside the pot and affecting the final cooking result. The water-filling buffer chamber 213 also cools the inner lid 21, preventing overflow. Overflow is a common problem during cooking, primarily due to excessively high temperatures and vigorous boiling. Injecting water into the water-filling buffer chamber 213 cools the upper part of the cooking chamber, lowering the temperature and preventing overflow.

[0067] In this embodiment, there are multiple through holes, and the diameter of each through hole is smaller than the inner diameter of the water pipe. Water is introduced into the cooking chamber through a buffer chamber and then distributed through multiple through holes, significantly reducing the impact on the food inside the pot. Generally, for water supply, the inner diameter of the water pipe is larger, while the diameter of the through holes is smaller, thus minimizing the impact on the food.

[0068] In this embodiment, the through-hole includes multiple oblique holes, forming a dispersed spray water injection. By adjusting the distribution of the through-holes, a dispersed spray water injection method can be formed; the distribution of the through-holes can be referenced from the water outlet of a shower head. This can expand the water injection coverage area, allowing all the food in the pot to come into contact with the injected water immediately.

[0069] The through hole can be formed directly on the inner cover, or it can be formed on other components installed at the water supply port of the inner cover.

[0070] One possible implementation is that the through hole is a strip-shaped hole, the width of which is smaller than the inner diameter of the water pipe.

[0071] In one possible implementation, the liner 22 is provided with a retaining rib, and the liner, inner cover, and retaining rib form a water-filling buffer cavity. The retaining rib is formed on the lower surface of the liner. After installation, the inner cover, together with the liner and retaining rib, forms a water-filling buffer cavity to accommodate water injected from the water tank, which then flows into the cooking cavity through a through-hole on the inner cover. Alternatively, a water pipe connector can be provided on the liner, with a water pipe connected to the connector, and the connector communicating with the water-filling buffer cavity.

[0072] In this embodiment, refer to Figure 7 and Figure 8The inner cover 21 is provided with a sealing ring 26, and the liner 22, the inner cover 21 and the sealing ring 26 form a water injection buffer cavity. Because of the sealing ring 26, it can serve as the side wall of the water injection buffer cavity.

[0073] Of course, the retaining ribs and sealing rings can also serve as the sidewalls of the water injection buffer chamber, which together with the liner and inner cover to form the water injection buffer chamber.

[0074] Furthermore, the sealing ring 26 has a bottom surface with a drain hole 261 forming thereon, which connects to the cooking cavity. Because of the sealing ring 26 and the drain hole 261 formed on its bottom surface, the shape of the drain hole can be customized on the bottom surface of the sealing ring to create various water inlet methods. As an example, the drain hole 261 shown in the figure of this embodiment is a cross shape composed of strip-shaped holes; however, it can also be multiple small through holes, multiple strip-shaped holes, square holes, or combinations thereof. Multiple oblique holes can also be provided on the bottom surface of the sealing ring to create a dispersed spray water inlet.

[0075] Regarding the water inlet method, it can be that the water pipe passes through the liner and enters the water injection buffer chamber, or it can be as follows: Figure 7 As shown, the liner 22 is equipped with a connector, and the water pipe 5 is connected to the connector to inject water into the water injection buffer chamber.

[0076] Alternatively, a steam valve can be installed on the pot lid, forming the water injection buffer chamber.

[0077] For other structures, the same principle can be applied as in Embodiment 1. For example, a drain outlet can be provided at the bottom of the inner liner, and a drain valve can be provided on the drain outlet.

[0078] Example 3

[0079] The main difference between this embodiment and Embodiment 1 lies in the water inlet method. Embodiment 1 involves injecting water into the cooking cavity through the water supply end, Embodiment 2 involves supplying water through a water inlet buffer chamber, and this embodiment involves supplying water through a steam valve. Of course, to a certain extent, the steam valve can also be understood as a water inlet buffer chamber. This embodiment will describe the steam valve water supply method.

[0080] In this embodiment, refer to Figures 9-12The pot lid 2 is equipped with a steam valve 25, and the water tank 4 is connected to the steam valve 25 via a water pipe to supply water to the cooking chamber. The steam valve 25 is a space for steam flow on the pot lid. The steam valve 25 has a steam inlet 24 and a steam outlet 28. The steam generated in the cooking chamber enters the steam valve through the steam inlet 24 and is discharged to the outside through the steam outlet 28. The water tank 4 is connected to the steam valve 25 via a water pipe 5, allowing water to be injected into the steam valve 25. This application cleverly utilizes the feature of the steam valve connecting to the cooking chamber, supplying water to the steam valve 25 and then into the cooking chamber. During the water supply process, the steam valve 25 is also cleaned and defoamed. Moreover, the opening connecting the steam valve to the cooking chamber can be used, eliminating the need for other openings on the inner lid, simplifying the structure of the inner lid, and still achieving the purpose of water supply. From the outside, there are no extra openings, as the openings are integrated into the steam valve structure.

[0081] Reference Figure 11 and Figure 12 The steam valve 25 has an inlet 251 and an outlet. The water pipe 5 is connected to the inlet 251 and the outlet is connected to the cooking chamber. Water enters the steam valve 25 through the inlet 251 and then flows into the cooking chamber through the outlet, thus supplying water to the cooking chamber through the steam valve 25.

[0082] The water outlet can be formed by the steam inlet 24, which connects to the cooking cavity. Since the steam inlet 24 connects to the cooking cavity, and this embodiment requires a water outlet to connect to the cooking cavity, the water outlet and the steam inlet can be shared.

[0083] Alternatively, refer to Figure 8 and Figure 11 The steam valve 25 is also provided with a return port 252, which forms the outlet connecting the cooking chamber. The steam valve 25 is generally provided with a return port 252 for the return of condensate formed by steam condensation, so the return port 252 can also be used as the outlet connecting the cooking chamber.

[0084] Reference Figure 11The return port 252 is equipped with an anti-overflow seal 27, which includes a base 271, a locking element 272, and a connecting post 273 connecting the base and the locking element. The base 271 is used to block the return port, and the locking element 272 can cooperate with the peripheral stop of the return port 252. With this structure, when steam is generated in the cooking chamber, the steam can enter the steam valve space through the steam inlet. In the steam valve space, due to the extension of the steam channel path, some of the steam will condense to form condensate, which flows back into the cooking chamber through the return port 252. The anti-overflow seal 27 has a certain vertical movement, so that when steam is generated in the cooking chamber, as the steam rises, because the base 271 blocks the return port, the steam will basically not directly enter the steam valve 25 from the return port. After the steam forms condensate in the steam valve, the condensate will flow out from the return port 252 due to gravity and eventually flow back into the cooking chamber. The return port 252 may be provided with multiple small through holes, the distribution area of ​​which is covered by the base 271. However, because the base 271 is located below the return port 252, the condensate can still flow back into the cooking cavity through the return port 252.

[0085] In this embodiment, the steam valve 25 has a steam passage, the inlet 251 is connected to the steam passage, and the steam outlet 28 of the steam passage is higher than the inlet 251. This arrangement can prevent water entering the steam valve 25 through the inlet 251 from being discharged from the steam outlet 28.

[0086] In this embodiment, the pot lid includes an inner lid 21 and a liner 22. A steam valve is located between the inner lid 21 and the liner 22, and a water pipe 5 passes through the liner 22 and connects to the steam valve. Specifically, the liner may have a perforation through which the water pipe passes to connect to the steam valve, or the liner may have a connecting joint on which the water pipe is fixed, and the connecting joint connects to the steam valve. The steam valve can be a separate component or a cavity with a steam passage formed between the inner lid and the liner, with a portion of the cavity formed by utilizing either the inner lid or the liner.

[0087] In this embodiment, the inner cover 21 is detachably mounted on the pot lid 2, and the steam valve 25 is detachably mounted on the inner cover. This allows for easy disassembly and cleaning of the inner cover 21 and the steam valve 25.

[0088] In this embodiment, a one-way valve is provided on the water pipe 5 to allow water to be supplied to the cooking cavity in one direction. Since the water pipe 5 supplies water to the cooking cavity, a one-way valve can be installed as needed to prevent liquid backflow in the cooking cavity.

[0089] This embodiment cleverly utilizes the feature of the steam valve connecting to the cooking chamber, using the space of the steam valve for water supply, which can clean the internal space of the steam valve, and there is no need to make additional openings on the inner cover. By using the opening of the steam valve to connect to the cooking chamber, the structure of the inner cover is simplified.
