Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to an electric steamer. BACKGROUND

[0002] Steam cooking can make food retain nutrients fully, and is one of the common cooking methods in daily life. Electric steamers are very common cooking appliances that use steam cooking. In the electric steamer with a water tank and a steam generating cavity arranged in a split type, a float valve is usually used to control the opening and closing of the water outlet of the water tank, so as to control the water level in the steam generating cavity at a low water level, which can realize rapid steam generation. However, when the water in the water tank is exhausted and the water level in the steam generating cavity is low, the steam in the steam generating cavity may flow back to the float cavity accommodating the float valve, and the float valve in the float cavity is easily deformed by high-temperature steam, resulting in water control failure. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide an electric steamer capable of avoiding steam flowing back to the float cavity to affect the effectiveness of the float valve.

[0004] An electric steamer includes a base, a cooking main body, a heating piece and a water tank assembly. The cooking main body is provided with a cooking cavity, and the cooking main body is arranged on the base. The base is provided with a steam generating cavity. The heating piece is used to heat water in the steam generating cavity to generate steam that can be delivered to the cooking cavity. The water tank assembly includes a water storage tank, a water control tank and a float valve. The water control tank is arranged below the water storage tank. A partition plate is arranged in the water control tank. The partition plate divides the inner cavity of the water control tank into a float cavity and a water outlet cavity. The water storage tank and the float cavity of the water control tank are communicated through a first outlet. The float valve is arranged in the float cavity. The float valve can rise and fall with the rise and fall of the water level in the float cavity and is used to control the opening and closing of the first outlet. The side wall of the water control tank is provided with a second outlet communicated with the water outlet cavity. The steam generating cavity is provided with a water inlet. The water inlet and the second outlet are communicated through a pipeline. The lower end of the partition plate is provided with a communication port. The communication port communicates the float cavity and the water outlet cavity. The lowest part of the inner wall of the second outlet is not lower than the highest part of the communication port.

[0005] The present application sets the partition plate in the inner cavity of the water control tank, and sets the communication port at the lower end of the partition plate, so as to ensure that the water level in the float cavity and the water level in the water outlet cavity rise and fall synchronously. Since the lowest part of the inner wall of the second outlet is not lower than the highest part of the inner wall of the communication port, when the steam in the steam generating cavity enters the water outlet cavity through the pipeline, the water levels of the water outlet cavity and the float cavity can still submerge the communication port, so that the steam cannot enter the float cavity through the communication port, and the float valve is not affected, thereby ensuring the effectiveness of the function of the float valve itself.

[0006] In one of the embodiments, the lower end of the partition plate is connected to the bottom wall of the inner cavity of the water control tank, and the communication port penetrates the lower end surface of the partition plate.

[0007] In this way, the structure is very simple, and the height of the communication port is larger in the case of being determined at the highest point of the communication port, thereby ensuring that the water in the float chamber can flow smoothly into the water outlet chamber.

[0008] In one of the embodiments, the lower end of the partition plate is not in contact with the bottom wall of the inner cavity of the water control tank to form the communication port.

[0009] In this way, the structure is more simple, and the size of the communication port is larger in the case of being determined at the highest point of the communication port, thereby ensuring that the water in the float chamber can flow smoothly into the water outlet chamber.

[0010] In one of the embodiments, the partition plate is integrally formed with the water control tank.

[0011] In this way, the structure is simple and easy to process.

[0012] In one of the embodiments, a limiting protrusion is arranged in the float chamber, and the limiting protrusion can abut against the bottom wall of the float valve when the float valve falls, so that there is a gap between the bottom wall of the float valve and the bottom wall of the float chamber.

[0013] In this way, the bottom wall of the float valve and the bottom wall of the float chamber are avoided from being attached together when the water level in the float chamber is low, thereby causing the float chamber to be unable to float after water is added and affecting the control function.

[0014] In one of the embodiments, the limiting protrusion is formed by protruding upward from the bottom wall of the float chamber.

[0015] In this way, the structure is very simple and easy to process.

[0016] In one of the embodiments, the water inlet is arranged on the side wall of the steam generating chamber, and the pipeline has a descending portion, the inner top wall at the lowest point of the descending portion is lower than the central axis of the water inlet, and the inner bottom wall at the lowest point of the descending portion is lower than the lowest point of the inner wall of the water inlet.

[0017] In this way, when the water in the water storage tank is exhausted and the water level in the steam generating chamber is lower than the water inlet, a part of water is retained in the descending portion of the pipeline, so that the steam in the steam generating chamber is not easy to flow into the water control tank through the pipeline, and at the same time, the part of water retained in the descending portion can cool the steam passing from above, so that the temperature of the steam entering the water control tank is reduced, thereby reducing the influence on the float valve.

[0018] In one of the embodiments, the inner top wall at the lowest point of the descending portion is lower than the lowest point of the inner wall of the water inlet.

[0019] Thus, the water in the descending part can play a partitioning role, preventing the steam in the steam generating cavity from entering the water control tank, so that the descending part and the partitioning plate play a double protection role, further ensuring that the steam does not enter the float cavity, thereby ensuring the effectiveness of the float valve.

[0020] In one embodiment, the descending part is U-shaped or V-shaped.

[0021] Thus, both ends of the descending part are higher than the middle part, the middle part of the descending part forms a lowest point, and the water inlet and the second outlet are both higher than the lowest point of the descending part, so that the water in the water control tank is more likely to flow into the steam generating cavity.

[0022] In one embodiment, the descending part gradually decreases in height from the end connected to the water inlet to the end connected to the second outlet.

[0023] Thus, when the water in the water storage tank is depleted, there is water in the water control tank that can submerge the second outlet, so that the water at the second outlet can partition the steam, preventing the steam from entering the water control tank through the second outlet. Moreover, the pipeline does not accumulate water, making it easy to clean. BRIEF DESCRIPTION OF DRAWINGS

The terminology used in the specification of the present application is only for the purpose of describing the specific embodiments of the present application, and is not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more relevant listed items.

[0039] Please refer to Figures 1 to 5The application provides an electric steamer, which comprises a base 10, a cooking main body 20, a heating piece 30 and a water tank assembly 40. The cooking main body 20 is provided with a cooking cavity 21, and the cooking main body 20 is arranged on the base 10. The base 10 is provided with a steam generating cavity 11. The heating piece 30 is used for heating water in the steam generating cavity 11 to generate steam which can be delivered to the cooking cavity 21, so as to cook food in the cooking cavity 21. The water tank assembly 40 comprises a storage water tank 41, a water control tank 42 and a float valve 43. The water control tank 42 is arranged below the storage water tank 41. The water control tank 42 is provided with a partition plate 421. The partition plate 421 divides the inner cavity of the water control tank 42 into a float cavity 422 and a water outlet cavity 423. The float cavity 422 of the storage water tank 41 and the water control tank 42 is communicated through a first outlet 411. The float valve 43 is arranged in the float cavity 422. The float valve 43 can rise and fall with the water level in the float cavity 422 and is used for controlling the opening and closing of the first outlet 411. The side wall of the water control tank 42 is provided with a second outlet 424 which is communicated with the water outlet cavity 423. The side wall of the steam generating cavity 11 is provided with a water inlet 111. The water inlet 111 and the second outlet 424 are communicated through a pipeline 50. The lower end of the partition plate 421 is provided with a communication port 4211 which communicates the float cavity 422 and the water outlet cavity 423. The lowest position of the inner wall of the second outlet 424 is not lower than the highest position of the inner wall of the communication port 4211. It is worth mentioning that the part of the partition plate 421 which is outside the communication port 4211 is not communicated, that is, the float cavity 422 and the water outlet cavity 423 are only communicated through the communication port 4211. When the first outlet 411 is opened, the water in the storage water tank 41 can pass through the first outlet 411, the float cavity 422, the communication port 4211, the water outlet cavity 423, the second outlet 424, the pipeline 50 and the water inlet 111 in sequence and finally enter the steam generating cavity 11. When the first outlet 411 is closed, the storage water tank 41 stops delivering water to the steam generating cavity 11. The application controls the opening and closing of the first outlet 411 through the float valve 43, so that the water level in the steam generating cavity 11 can be controlled, thereby only a small amount of water needs to be heated to generate steam, so that the function of quickly generating steam is realized. Meanwhile, when the water level in the steam generating cavity 11 decreases, the float valve 43 opens the first outlet 411, so that the water in the storage water tank 41 can be automatically supplemented into the steam generating cavity 11, so that the steam generating cavity 11 can continuously generate steam.The application sets the partition plate 421 in the inner cavity of the water control tank 42, and sets the communication port 4211 at the lower end of the partition plate 421, so as to ensure that the water level in the float chamber 422 and the water level in the water outlet chamber 423 are synchronous. Since the lowest part of the inner wall of the second outlet 424 is not lower than the highest part of the inner wall of the communication port 4211, when the steam in the steam generation chamber 11 enters the water outlet chamber 423 through the pipeline 50, the water level of the water outlet chamber 423 and the float chamber 422 can still submerge the communication port 4211, so that the steam cannot enter the float chamber 422 through the communication port 4211, and the float valve 43 will not be affected, so as to ensure the effectiveness of the function of the float valve 43.

[0040] Please refer to Figure 2 In an embodiment, the cooking main body 20 includes the pot cover 22, and the inner side of the pot cover 22 forms the cooking cavity 21. The cooking cavity 21 can be provided with the steamer 23 for supporting the food to be steamed. In addition, in other embodiments, the cooking main body 20 can also include the steamer 24, and the inner side of the steamer 24 forms the cooking cavity 21, or the steamer 24 and the pot cover 22 enclose the cooking cavity 21. The application does not limit this, as long as the cooking main body 20 is provided with the cooking cavity 21 capable of accommodating food.

[0041] The heating element 30 is arranged on the bottom wall of the steam generation chamber 11, so that the heating element 30 heats the water in the steam generation chamber 11 to generate steam. Of course, in other embodiments, the heating element 30 can also be arranged in the steam generation chamber 11, or the heating element 30 extends into the steam generation chamber 11. The application does not limit this, as long as the heating element 30 can heat the water in the steam generation chamber 11 to generate steam. In addition, the heating element 30 can also heat the steam to form high-temperature steam, so as to improve the cooking efficiency.

[0042] The water storage tank 41 and the water control tank 42 can be an integrated structure or a split structure, and the application does not limit this. As long as the water storage tank 41 can supply water to the water control tank 42 through the first outlet 411. In an embodiment, the water control tank 42 is fixed to the base 10, and the water storage tank 41 is detachably connected to the base 10, so as to facilitate the replacement and cleaning of the water storage tank 41.

[0043] Please refer to Figure 3The float valve 43 is arranged in the float cavity 422, and the float valve 43 can be directly matched with the first outlet 411 to open and close the first outlet 411, or the float valve 43 can be matched with the first outlet 411 through a lever structure, the float valve 43 drives the lever structure to rotate through the lifting of the float valve 43, and the first outlet 411 is opened and closed through the blocking component on the lever structure. The cooperation structure of the float valve 43 and the first outlet 411 is not limited in the application, as long as the lifting of the float valve 43 can control the opening and closing of the first outlet 411. In the embodiment, the communication port 4211 is one, but is not limited to this, and in other embodiments, the communication port 4211 can also be provided as multiple.

[0044] Please refer to Figure 4 and Figure 5 In an embodiment, the lower end of the partition plate 421 is connected to the inner cavity bottom wall of the water control tank 42, and the communication port 4211 penetrates the lower end surface of the partition plate 421. In this way, the structure is very simple, and the height dimension of the communication port 4211 is larger in the case of being determined at the highest point of the communication port 4211, thereby ensuring that the water in the float cavity 422 can flow smoothly into the water outlet cavity 423.

[0045] Please refer to Figure 6 In another embodiment, the lower end of the partition plate 421 is not in contact with the inner cavity bottom wall of the water control tank 42 to form the communication port 4211. In this way, the structure is simpler, and the size of the communication port 4211 is larger in the case of being determined at the highest point of the communication port 4211, thereby ensuring that the water in the float cavity 422 can flow smoothly into the water outlet cavity 423.

[0046] Further, the communication port 4211 is provided as a square through hole, but is not limited to this, and in other embodiments, the communication port 4211 can be provided as a circular, semicircular, trapezoidal or other shape through hole, as long as the communication port 4211 can realize the communication between the float cavity 422 and the water outlet cavity 423.

[0047] Further, the partition plate 421 is integrally formed on the water control tank 42. In this way, the structure is simple and easy to process.

[0048] Please refer to Figure 4 and Figure 5 In an embodiment, the float cavity 422 is provided with a limiting protrusion 4221, and the limiting protrusion 4221 can abut against the bottom wall of the float valve 43 when the float valve 43 falls down, so that there is a gap between the bottom wall of the float valve 43 and the bottom wall of the float cavity 422. In this way, it is avoided that the bottom wall of the float valve 43 and the bottom wall of the float cavity 422 are attached together when the water level in the float cavity 422 is low, thereby causing the float cavity 422 to be unable to float after adding water and affecting the control function.

[0049] In an embodiment, the limiting protrusion 4221 is formed on the bottom wall of the float cavity 422, so that the structure is very simple and easy to process. Of course, in other embodiments, the limiting protrusion 4221 can also be arranged on the side wall of the float cavity 422, as long as the limiting protrusion 4221 can support the float valve 43, so that there is a gap between the bottom wall of the float valve 43 and the bottom wall of the float cavity 422.

[0050] In the embodiment, the limiting protrusion 4221 is a spherical protrusion, and when the limiting protrusion 4221 and the bottom wall of the float valve 43 are in contact, the contact area is small, so that the float valve 43 will not be unable to float up because of being attached to the limiting protrusion 4221. Of course, in other embodiments, the limiting protrusion 4221 can also be a cylindrical protrusion, a prismatic protrusion, a circular truncated cone protrusion or any other shape of protrusion, as long as the limiting protrusion 4221 does not affect the normal floating of the float valve 43 after being in contact with the bottom wall of the float valve 43.

[0051] Please refer to Figure 2 In an embodiment, the lowest position of the inner wall of the water inlet 111 and the lowest position of the inner wall of the second outlet 424 are at the same height, and the pipeline 50 is a straight pipe, so that the structure is very simple.

[0052] Please refer to Figure 7 and Figure 8 In another embodiment, the water inlet 111 is arranged on the side wall of the steam generating cavity 11, and the pipeline 50 has a descending portion 51, the inner top wall of the lowest position of the descending portion 51 is lower than the central axis of the water inlet 111, and the inner bottom wall of the lowest position of the descending portion 51 is lower than the lowest position of the inner wall of the water inlet 111. In this way, when the water in the water storage tank 41 is exhausted and the water level in the steam generating cavity 11 is lower than the water inlet 111, a part of water will be retained in the descending portion 51 of the pipeline 50, so that the steam in the steam generating cavity 11 is not easy to flow into the water control tank 42 through the pipeline 50. At the same time, since the descending portion 51 retains a part of water, the part of water can cool the steam passing from above, so that the temperature of the steam entering the water control tank 42 is reduced, thereby reducing the influence on the float valve 43.

[0053] Further, the inner top wall of the lowest position of the descending portion 51 is lower than the lowest position of the inner wall of the water inlet 111. In this way, the water in the descending portion 51 can play a blocking role to prevent the steam in the steam generating cavity 11 from entering the water control tank 42, so that the setting of the descending portion 51 and the setting of the partition plate 421 play a double protection role, further ensuring that the steam will not enter the float cavity 422, thereby ensuring the effectiveness of the float valve 43.

[0054] Please refer to Figure 7In one embodiment, the descending portion 51 is in a U shape or a V shape, so that both ends of the descending portion 51 are higher than the middle portion, that is, the middle portion of the descending portion 51 forms the lowest point, and correspondingly, the water inlet 111 and the second outlet 424 are both higher than the lowest point of the descending portion 51, so that the water in the control water tank 42 is more easily flowed into the steam generating cavity 11.

[0055] Please refer to Figure 8 In another embodiment, the descending portion 51 gradually decreases in height from the end connected to the water inlet 111 to the end connected to the second outlet 424. In this way, when the water in the water storage tank 41 is exhausted, there is water in the control water tank 42 that can submerge the second outlet 424, so that the water at the second outlet 424 can block the steam, avoiding the steam from the second outlet 424 into the control water tank 42. In addition, such a structure makes it possible that the pipeline 50 does not accumulate water, and is easy to clean.

[0056] The technical features of the above embodiments can be combined in any way. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present disclosure.

[0057] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
