Description

[Technical field]

[0001] The utility model relates to the technical field of electric steamers, in particular to an electric steamer with an external water tank. [Background technology]

[0002] An electric steamer in the prior art includes a base, a steamer assembly arranged on the base, and an outer water tank. A steam generating chamber is arranged in the base, a water outlet and a connecting pipe integrally formed with the outer water tank are arranged on the wall of the outer water tank, the connecting pipe is connected to the water outlet, and a water inlet is arranged on the wall of the steam generating chamber. One end of the connecting pipe is inserted into the water inlet so that the outer water tank supplies water to the steam generating chamber through the connecting pipe. In order to prevent water leakage at the connection between the connecting pipe and the wall of the steam generating chamber, a sealing ring is also arranged between the connecting pipe and the hole wall of the water inlet. During assembly, since the connecting pipe of the side water tank is a long hard pipe, in order to facilitate its passage through the outer shell of the base and connection with the water inlet in the base, a larger installation window needs to be opened in the outer shell. The larger the installation window, the easier it is for the water between the outer shell and the outer water tank to enter the base through the installation window, thereby increasing the probability of damage to the internal electrical components. In addition, when the electric steamer is in use, the steam in the steam generating chamber will also enter the connecting pipe, and the connecting pipe will be deformed after being heated, which will affect the coaxiality of the connecting pipe and the water inlet, making it more difficult to disassemble and assemble the connecting pipe and the water inlet, and also reduce the sealing of the connecting pipe and the water inlet.

[0015] Beneficial effects of the utility model:

[0016] 1. The connecting pipe in the utility model is a flexible sealing pipe. Since the flexible sealing pipe is elastic, it can be adaptively deformed to a certain extent according to the installation requirements to reduce the coaxiality and parallelism requirements of the water inlet and the water outlet, that is, the tolerance rate of the processing errors of the water inlet and the water outlet and the installation errors of the outer water tank is high, thereby reducing the processing accuracy requirements of the water inlet and the water outlet and the installation accuracy requirements of the outer water tank, and also reducing the difficulty of disassembly and assembly of the connecting pipe; in addition, since one end of the flexible sealing pipe is sealed and connected to the wall of the outer water tank, and the other end is sealed and connected to the steam The wall of the generating chamber is sealed and connected, so the wall of the outer water tank and the wall of the steam generating chamber can be used to achieve a sealed connection, which can ensure the sealing reliability and also save the sealing ring; furthermore, the outer shell part between the wall of the steam generating chamber and the outer water tank only needs to open a through hole that is compatible with the connecting pipe, so as to reduce the aperture of the through hole and thus reduce the probability of water entering the base; finally, since the flexible sealing tube is processed and formed separately, there is no need to process a long straight connecting tube on the outer water tank, thereby reducing the processing difficulty of the outer water tank and thus reducing the manufacturing cost of the product.

[0017] 2. The inner side of the wall of the outer water tank is also provided with a first convex ring arranged around the water outlet, and one end of the flexible sealing tube has a first sealing section inserted into the water outlet, and the end surface of the first sealing section is provided with a first folded edge buckled on the first convex ring. With such a design, the cooperation between the first folded edge and the first convex ring can prevent the first sealing section from moving to the outside of the outer water tank and detaching from the water inlet, thereby ensuring the installation reliability of the first sealing section and the wall of the outer water tank. In addition, the first folded edge can also form a double seal with the first convex ring, thereby improving the sealing reliability.

[0018] 3. A second convex ring arranged around the water inlet is also provided on the inner side of the wall of the steam generating chamber, and the other end of the flexible sealing tube has a second sealing section inserted into the water inlet, and the end surface of the second sealing section is provided with a second folded edge buckled on the second convex ring.

[0019] 4. The flexible sealing tube includes a large diameter section and a small diameter section. The large diameter section is sealed and connected to the wall of the steam generating chamber, and the small diameter section is sealed and connected to the wall of the outer water tank. With this design, the steam can be blocked to a certain extent by the small diameter section to prevent it from entering the outer water tank too much or too quickly, thereby reducing the impact of high-temperature steam on the outer water tank and preventing the outer water tank from deformation.

[0020] 5. The water outlet is arranged on the side wall of the outer water tank and close to the bottom wall of the outer water tank, and the water inlet is arranged on the side wall of the steam generating chamber. Such a design can make the flexible sealing tube straight, so as to effectively shorten the length of the flexible sealing tube, that is, shorten the water flow path, so that the outer water tank can supply water to the steam generating chamber in time, and at the same time reduce the material cost of the flexible sealing tube.

[0021] 6. The flexible sealing tube includes two sub-sealing tubes formed separately, one end of the two sub-sealing tubes is sealed and connected to the wall of the outer water tank and the wall of the steam generating chamber respectively, and the other ends of the two sub-sealing tubes are sealed and sleeved. With such a design, during assembly, the two sub-sealing tubes can be installed to the wall of the steam generating chamber and the wall of the outer water tank respectively, and then when the outer water tank is installed on the base, the other ends of the two sub-sealing tubes can be sealed and sleeved.

The base also includes an inner shell defining a steam generating chamber and an outer shell disposed outside the inner shell, the outer shell defining a platform for placing an outer water tank, a portion of the outer shell between the steam generating chamber and the outer water tank being provided with a through hole for the connecting pipe to pass through, and an outer wall of the flexible sealing tube being provided with a sealing sheet extending radially outward, the sealing sheet being tightly sealed with the outer shell. Such a design can prevent the water between the outer shell and the outer water tank from entering the base through the through hole, thereby reducing the probability of damage to the internal electrical components, increasing the service life of the electric steamer, and eliminating the drainage channel structure corresponding to the through hole on the existing base, thereby simplifying the structure of the base and greatly improving the sealing of the whole machine.

[0023] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0034] Embodiment 1

[0035] like Figures 1 to 4 As shown, the electric steamer with an external water tank in this embodiment includes a base 100, a steamer assembly 200 arranged on the base 100, and an external water tank 300. A steam generating chamber 110 is provided in the base 100, a water outlet 301 is provided on the wall of the external water tank 300, a water inlet 111 is provided on the wall of the steam generating chamber 110, a connecting pipe 400 is provided between the water outlet 301 and the water inlet 111, so that the external water tank 300 supplies water to the steam generating chamber 110 through the connecting pipe 400, and the connecting pipe 400 is a flexible sealing tube, one end of the flexible sealing tube is sealed and connected to the wall of the external water tank 300, and the other end is sealed and connected to the wall of the steam generating chamber 110.

[0036] The connecting tube 400 in the present embodiment is a flexible sealing tube. Since the flexible sealing tube is elastic, it can be adaptively deformed to a certain extent according to the installation requirements to reduce the coaxiality and parallelism requirements of the water inlet 111 and the water outlet 301, that is, the tolerance rate for the processing errors of the water inlet 111 and the water outlet 301 and the installation errors of the outer water tank 300 is high, thereby reducing the processing accuracy requirements of the water inlet 111 and the water outlet 301 and the installation accuracy requirements of the outer water tank 300, and also reducing the difficulty of disassembly and assembly of the connecting tube 400; in addition, since one end of the flexible sealing tube is sealedly connected to the wall of the outer water tank 300 and the other end is sealed to the steam tank 300, the water inlet 111 and the water outlet 301 are sealed to the steam tank 300. The wall of the steam generating chamber 110 is sealed and connected, so the wall of the outer water tank 300 and the wall of the steam generating chamber 110 can be sealed and connected by itself, so that the sealing reliability can be ensured and the sealing ring can be omitted; furthermore, the outer shell part between the wall of the steam generating chamber 110 and the outer water tank 300 only needs to have a through hole that is compatible with the connecting pipe 400, so as to reduce the aperture of the through hole, thereby reducing the probability of water entering the base 100; finally, since the flexible sealing tube is processed and formed separately, there is no need to process a long straight connecting tube on the outer water tank 300, thereby reducing the processing difficulty of the outer water tank 300 and reducing the manufacturing cost of the product.

[0037] Better, reference Figure 1 The base 100 in this embodiment includes a shell 120 and a bottom cover 130 detachably mounted on the bottom of the shell 120. The lower end of the shell 120 is open, and the bottom cover 130 is connected to the shell 120 to form a cavity for accommodating electronic components such as a main control board and a heating element; the shell 120 includes an inner shell 121 and an outer shell 122. The inner shell 121 is partially sunken to define the above-mentioned steam generating chamber 110, that is, the inner shell 121 forms the wall of the steam generating chamber 110; the outer shell 122 surrounds the outer side of the inner shell 121, and a part of the outer shell 122 is bent to form a platform 1220 located on one side of the inner shell 121. The outer water tank 300 is placed on the platform 1220, and the heating element is arranged on the bottom wall of the inner shell 121 to heat the water in the steam generating chamber 110. The water is heated to form steam, and the steam enters the steamer assembly 200 to heat the food.

[0038] For further reference, Figure 1 The outer water tank 300 includes a box body and a box cover. The box body can be detachably connected to the platform 1220 so that the user can disassemble it for cleaning, or it can be fixedly connected to the platform 1220 by screws, etc., which is not limited here. The box cover is set on the box body, and it can be taken down during cooking to add water to the box body without taking out the steamer assembly, which is convenient to use.

[0039] In order to shorten the length of the connecting pipe 400, refer to Figure 1In this embodiment, the water outlet 301 is arranged on the side wall of the outer water box 300 and close to the bottom wall of the outer water box 300, and the water inlet 111 is arranged on the side wall of the steam generating chamber 110 (i.e., the side wall of the inner shell 121). Such a design can make the flexible sealing tube in a straight tube shape, which is convenient for processing and manufacturing on the one hand, and can also effectively shorten the length of the flexible sealing tube on the other hand, that is, shorten the flow path of water, so that the outer water box 300 can supply water to the steam generating chamber 110 in time, and also reduce the material cost of the connecting pipe 400.

[0040] In order to enhance the connection reliability and sealing reliability between the connecting pipe 400 and the side wall of the outer water tank 300, refer to Figure 3 and Figure 4 In this embodiment, a first convex ring 302 is further provided on the inner side of the side wall of the outer water tank 300 around the water outlet 301, and one end of the flexible sealing tube has a first sealing section 410 inserted into the water outlet 301, and the end face of the first sealing section 410 is provided with a first folded edge 411 which is extended radially outward and bent toward the other end of the flexible sealing tube, and the first folded edge 411 is buckled on the first convex ring 302 and contacts and seals with the first convex ring 302. With such a design, the cooperation between the first folded edge 411 and the first convex ring 302 can prevent the first sealing section 410 from moving to the outside of the outer water tank 300 and detaching from the water outlet 301, thereby ensuring the installation reliability of the first sealing section 410 and the side wall of the outer water tank; in addition, the first folded edge 411 can also form a double seal with the first convex ring 302, thereby improving the sealing reliability.

[0041] In addition, in order to enhance the connection reliability and sealing reliability between the connecting pipe 400 and the side wall of the steam generating chamber 110, reference Figure 3 and Figure 4 In this embodiment, the inner side of the side wall of the steam generating chamber 110 (the side wall of the inner shell 121) is also provided with a second convex ring 112 arranged around the water inlet 111, and the other end of the flexible sealing tube has a second sealing section 420 inserted into the water inlet 111, and the end surface of the second sealing section 420 is provided with a second folded edge 421 formed by extending radially outward and bending toward the end of the first sealing section 410, and the second folded edge 421 is buckled on the second convex ring 112. With such a design, the cooperation between the second folded edge 421 and the second convex ring 112 can prevent the second sealing section 420 from moving toward the steam generating chamber 110 and separating from the water inlet 111, thereby ensuring the installation reliability of the second sealing section 420 and the side wall of the inner shell 121; in addition, the second folded edge 421 can also form a double seal with the second convex ring 112, thereby improving the sealing reliability.

[0042] In order to further enhance the sealing reliability between the second folded folded edge 421 and the second convex ring 112, a plurality of second convex ribs are further provided on the inner side surface of the second folded folded edge 421, and the second convex ribs are in sealing contact with the surface of the second convex ring 112. More preferably, a plurality of second convex ribs are also provided on the outer peripheral side of the second sealing section 420, and the second convex ribs are in sealing contact with the wall of the water inlet 111.

[0043] Optional, reference Figure 3 and Figure 4 The flexible sealing tube in this embodiment includes a large diameter section and a small diameter section. The large diameter section is sealed and connected to the wall of the steam generating chamber 110, and the small diameter section is sealed and connected to the wall of the outer water tank 300. The first sealing section 410 in this embodiment is a small diameter section, and the second sealing section 420 is a large diameter section, so that the flexible sealing tube forms a stepped tube. With such a design, the steam can be blocked to a certain extent by the small diameter section to prevent it from entering the outer water tank 300 too much or too quickly, so as to reduce the influence of high-temperature steam on the outer water tank 300 and prevent the outer water tank 300 from deformation.

[0044] Preferably, the flexible sealing tube is an integrally formed part. Such a design can ensure the sealing performance of the entire water passage inside the flexible sealing tube to prevent water leakage in the water passage.

[0045] Preferably, the flexible sealing tube is a food-grade silicone member or a food-grade rubber member to improve the hygiene and safety of the electric steamer.

[0046] During the use of the electric steamer, when water is added to the side water tank or the side water tank is cleaned, it is inevitable that water will spill into the gap between the outer water tank and the shell, enter the base through the installation window, and then cause damage to the internal electrical components. For this reason, there is a solution in the prior art to set a drainage channel corresponding to the installation window to drain the water entering from the installation window to the outside of the electric steamer. However, half of this drainage channel is set on the shell, and the other half is set on the bottom cover. The two are simply plugged in without sealing, and there is still a hidden danger of water ingress. This increases the structural complexity of the electric steamer and increases the production cost.

[0047] Therefore, reference Figure 1 , Figure 3 and Figure 4The base 100 includes an inner shell 121 defining a steam generating chamber 110 and an outer shell 122 disposed outside the inner shell 121. The outer shell 122 defines a platform 1220 for placing an external water tank. The portion of the outer shell 122 located between the steam generating chamber 110 and the external water tank 300 in this embodiment is provided with a perforation 1221. The connecting pipe 400 can be provided through the perforation 1221. The outer peripheral side of the connecting pipe 400 is interference-fitted with the hole wall of the perforation 1221. The outer wall of the flexible sealing tube is provided with a sealing sheet 430 extending radially outward. The sealing sheet 430 is tightly sealed with the outer shell 122. Such a design can prevent the water between the outer shell 122 and the external water tank 300 from entering the perforation 1221, thereby eliminating the drainage channel structure corresponding to the perforation on the existing base, thereby simplifying the structure of the base and greatly improving the sealing performance of the whole machine.

[0048] Better, reference Figure 4 The sealing sheet 430 includes an annular sheet body 431 and a plurality of annular sealing ribs 432 convexly provided on the annular sheet body 431. The sealing ribs 432 surround the outside of the through hole 1221 and are closely attached to the outer side of the housing 122. With such a design, when the outer side of the housing 122 is uneven, the sealing ribs 432 can be adapted to deform to closely attach to the outer side of the housing 122 to form a seal, thereby ensuring the sealing performance between the sealing sheet 430 and the outer side of the housing 122.

[0049] When assembling the connecting pipe 400 of the electric steamer in this embodiment, first, pass the connecting pipe 400 through the water inlet 111 and the through hole 1221 in sequence, so that the second folded edge 421 is buckled on the second convex ring 112 and the first sealing section 410 is exposed, and then after the water outlet 301 and the first sealing section 410 are aligned, the outer water tank 300 is placed on the platform 1220, and the first folded edge 411 is buckled on the first convex ring 302 by pulling it with hands or tools, and finally the bottom cover 130 is assembled.

[0050] It is understandable that in other embodiments of the present invention, a first positioning sleeve penetrating through a hole in the outer shell is provided on the outer side of the side wall of the outer water tank, and one end of the connecting pipe is sealed and sleeved on the first positioning sleeve in an interference fit manner.

[0051] Embodiment 2

[0052] Compared with Example 1, the difference of this embodiment is that: the water inlet is arranged on the bottom wall of the outer water tank, and the water outlet is arranged on the bottom wall of the steam generating chamber. The connecting pipe is a U-shaped pipe. One end of the connecting pipe is sealedly connected to the bottom wall of the steam generating chamber, and the other end is sealedly connected to the bottom wall of the through-platform and the outer water tank. The specific sealing connection method can be referred to the description in Example 1 and will not be described in detail here.

[0053] Embodiment 3

[0054] Compared with the first and second embodiments, the difference of this embodiment is that the flexible sealing tube includes two sub-sealing tubes formed separately, one end of the two sub-sealing tubes is respectively sealed and connected to the wall of the outer water box and the wall of the steam generating chamber, and the specific sealing connection method can be referred to the first embodiment, which will not be described in detail here, and the other ends of the two sub-sealing tubes are sealed and sleeved. With such a design, during assembly, the two sub-sealing tubes can be installed on the wall of the steam generating chamber and the wall of the outer water box respectively, and then when the outer water box is installed on the base, the other ends of the two sub-sealing tubes can be sealed and sleeved.

[0055] In order to facilitate the sealing connection of the other ends of the two sub-sealing tubes, the wall thickness of the other ends of the two sub-sealing tubes in this embodiment is thickened to reduce the flexibility of the other ends of the two sub-sealing tubes and make them have a certain structural strength to facilitate the sealing connection of the other ends of the two sub-sealing tubes.

[0056] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
