Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an electric steamer.

Background Art

[0002] The electric steamer in the prior art includes a base, a juice receiving tray carried on the base, and a plurality of steaming chambers provided above the juice receiving tray. The juice receiving tray and the base define a steam generating chamber capable of accommodating water. A heating plate for heating the steam generating chamber is provided in the base. The heating plate heats the water in the steam generating chamber to evaporate it to form steam. A heating element, a gas guiding cover and a water isolating cover sleeved outside the heating element in sequence from inside to outside are further provided in the steam generating chamber. A steam inlet and a steam outlet are provided on the water isolating cover. The gas guiding cover is hermetically connected to the water isolating cover, and a steam inlet channel communicating with the steam inlet is formed therebetween. An outlet channel is formed between the gas guiding cover and the heating element. The outlet channel communicates the inlet channel with the steam outlet. In this way, steam can enter the water isolating cover through the steam inlet and then flow through the inlet channel and the outlet channel in sequence. The steam will be reheated by the heating element again during the process of flowing through the outlet channel to form superheated steam. The superheated steam is discharged through the steam outlet and flows to the steaming chamber above the juice receiving tray to heat the food in the steaming chamber.

[0003] In order to reduce the leakage of superheated steam and make the superheated steam enter the steaming chamber as much as possible, a sealing member needs to be provided between the steam outlet of the water isolating cover and the juice receiving tray to seal the gap therebetween. The sealing member can guide the superheated steam through the juice receiving tray to the steaming chamber above. The water isolating cover and the sealing member need to be assembled to achieve their sealed connection. In this way, not only the assembly steps are increased, but also the problem of sealing failure at the connection between the two is likely to occur due to improper assembly, resulting in steam leakage and reducing the cooking efficiency.

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an electric steamer, which not only reduces the assembly steps and improves the assembly efficiency, but also can effectively prevent steam leakage, thereby ensuring the cooking efficiency.

[0005] To solve the above technical problem, the utility model adopts the following technical scheme:

[0006] An electric steam cooker, comprising a base and a juice receiving tray carried on the base. The juice receiving tray and the base define a steam generating cavity for generating steam. A heating element, a gas guiding cover and a water separating cover which are sleeved on the outside of the heating element in sequence from inside to outside are arranged in the steam generating cavity. The water separating cover comprises an integrally formed cover body and a sealing sleeve. A steam inlet and a steam outlet are arranged on the cover body. The gas guiding cover is hermetically connected to the cover body and an air inlet channel communicating with the steam inlet is formed therebetween. An air outlet channel is formed between the gas guiding cover and the heating element. The air outlet channel communicates the air inlet channel with the steam outlet. The sealing sleeve is arranged around the steam outlet and hermetically connected to the juice receiving tray to guide the steam discharged from the steam outlet above the juice receiving tray.

[0007] In the above-mentioned electric steam cooker, the cover body comprises a sealing connection part arranged between the steam inlet and the steam outlet. The gas guiding cover is independently processed and formed. The gas guiding cover and the sealing connection part are cooperatively fixed to separate the steam inlet and the steam outlet.

[0008] In the above-mentioned electric steam cooker, both the steam inlet and the steam outlet are arranged on the top wall of the cover body. The steam inlet is located on the outer periphery of the steam outlet. The sealing connection part is a flanging formed by bending the edge of the steam outlet inward. A slot is formed between the sealing connection part and the top wall of the cover body. An opening corresponding to the steam outlet is arranged on the top wall of the gas guiding cover. The edge of the opening is inserted into the slot.

[0009] In the above-mentioned electric steam cooker, the water separating cover is made of a soft material, and at least one reinforcing rib is convexly provided on the inner side wall of the cover body.

[0010] In the above-mentioned electric steam cooker, the reinforcing rib abuts against the outer side surface of the gas guiding cover. An avoidance groove is arranged on the reinforcing rib. The avoidance groove communicates the air inlet channels on both sides of the reinforcing rib. An air inlet hole communicating the air inlet channel with the air outlet channel is arranged on the side wall of the gas guiding cover. The height position where the air inlet hole is located corresponds to the height position of at least one of the avoidance grooves.

[0011] In the above-mentioned electric steam cooker, the number of the reinforcing ribs is at least two. The reinforcing ribs are rib structures extending vertically. The reinforcing ribs abut against the outer side surface of the gas guiding cover, and the air inlet channels are formed between adjacent two of the reinforcing ribs.

[0012] In the above-mentioned electric steam cooker, at least one sealing rib is convexly provided on the inner side surface of the cover body. The gas guiding cover is provided with an air inlet part communicating the air inlet channel with the air outlet channel. The sealing rib is located below the air inlet part and abuts against and seals the outer side surface of the gas guiding cover.

[0013] In the above-mentioned electric steam cooker, heating protrusions protruding radially outward are arranged at intervals along the circumference of the heating element, and the air outlet channels are formed between adjacent two of the heating protrusions.

[0014] In the above-mentioned electric steamer, an installation boss is provided in the steam generation cavity, the heating element is arranged on the installation boss, a clamping groove is arranged on the periphery of the installation boss, a curled edge formed by inward winding is arranged at the bottom of the air guide cover, and the curled edge is clamped into the clamping groove.

[0015] In the above-mentioned electric steamer, the water separation cover is a silica gel part or a rubber part, and the air guide cover is a metal part.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The water separation cover in the present utility model includes an integrally formed cover body and a sealing sleeve. The cover body is provided with a steam inlet and a steam outlet. The air guide cover is hermetically connected to the cover body, and a steam inlet channel communicating with the steam inlet is formed therebetween. An air outlet channel is formed between the air guide cover and the heating element. The air outlet channel communicates the air inlet channel with the steam outlet. The sealing sleeve is arranged around the steam outlet and is hermetically connected to the juice receiving tray to guide the steam discharged from the steam outlet above the juice receiving tray. With such a design, by integrally processing and forming the cover body and the sealing sleeve, not only can the assembly steps of the cover body and the sealing sleeve be omitted to improve the assembly efficiency, but also the sealing performance at the connection between the cover body and the sealing sleeve can be ensured to prevent steam from leaking through this place. As a result, all the steam discharged from the steam outlet can flow above the juice receiving tray, thereby ensuring the cooking efficiency.

[0018] 2. The cover body includes a sealing connection part arranged between the steam inlet and the steam outlet. The air guide cover is independently processed and formed. The air guide cover is fixedly matched with the sealing connection part to separate the steam inlet and the steam outlet. With such a design, the water separation cover and the air guide cover can be separately processed and formed, so as to reduce the processing difficulty of the water separation cover and the air guide cover. At the same time, the two can be prepared from different materials according to needs to increase the diversity of products. Finally, by fixedly matching the sealing connection part with the air guide cover to separate the steam inlet and the steam outlet, it can also prevent the steam entering the cover body from the steam inlet from flowing to the steam outlet, so that the steam can flow along the preset flow path and be discharged from the steam outlet.

[0019] 3. Both the steam inlet and the steam outlet are provided on the top wall of the cover body. The steam inlet is located on the outer periphery of the steam outlet. The sealing connection part is a flanging formed by bending the edge of the steam outlet inward. A slot is formed between the sealing connection part and the top wall of the cover body. The top wall of the air guide cover is provided with an opening corresponding to the steam outlet, and the edge of the opening is inserted into the slot. By arranging the steam inlet on the top wall of the cover body, the installation height of the steam inlet can be increased to prevent the water in the steam generation cavity from entering the cover body through the steam inlet, resulting in the heating element heating the water in the cover body to boil and generate relatively large noise. In addition, when assembling the air guide cover and the cover body, the cooperation and fixation of the air guide cover and the sealing connection part can be realized by inserting the edge of the opening into the slot. This fixation method not only makes the fixation of the two relatively simple and convenient, but also has a high fixation strength, and can also achieve multiple seals at the fixation part to improve the sealing performance between the cover body and the air guide cover.

[0020] 4. The water isolation cover is made of a soft material, and at least one reinforcing rib is convexly provided on the inner side wall of the cover body. Designed in this way, the processing technology of the water isolation cover can be simplified, thereby reducing the processing difficulty of the water isolation cover. In addition, by arranging the reinforcing ribs, the structural strength of the cover body can be increased to ensure the stability of the shape of the cover body, and thus ensure the smoothness of the steam inlet channel.

[0021] 5. The reinforcing rib abuts against the outer side surface of the air guide cover. An avoidance groove is provided on the reinforcing rib, and the avoidance groove communicates with the steam inlet channels on both sides of the reinforcing rib. An air inlet hole communicating the steam inlet channel and the steam outlet channel is provided on the side wall of the air guide cover, and the height position where the air inlet hole is located corresponds to the height position of at least one avoidance groove. By the abutment of the reinforcing rib against the outer side surface of the air guide cover, the support of the cover body can be realized to ensure the stability of the shape of the cover body. In addition, by arranging the avoidance groove to communicate with the steam inlet channels on both sides of the reinforcing rib, and the height position where the air inlet hole is located corresponds to the height position of at least one avoidance groove, the air intake efficiency can be improved to enhance the cooking efficiency.

[0022] 6. The number of the reinforcing ribs is at least two. The reinforcing ribs are vertically extending rib structures. The reinforcing ribs abut against the outer side surface of the air guide cover, and a steam inlet channel is formed between adjacent two reinforcing ribs. Designed in this way, by arranging multiple reinforcing ribs, the structural strength of the cover body can be further enhanced to ensure the stability of the shape of the cover body, and thus ensure the smoothness of each steam inlet channel.

[0023] 7. At least one sealing rib is convexly provided on the inner side surface of the cover body. The air guide cover is provided with an air inlet part communicating the steam inlet channel and the steam outlet channel. The sealing rib is located below the air inlet part and abuts and seals against the outer side surface of the air guide cover. Designed in this way, the sealing performance between the cover body and the outer side surface of the air guide cover can be improved to prevent the steam in the steam inlet channel from leaking to the outside of the cover body. At the same time, the sealing rib can be sealed against the air guide cover only by sleeving the cover body outside the air guide cover, thereby reducing the assembly difficulty between the air guide cover and the water isolation cover.

[0024] 8. The heating element is provided with radially protruding heating protrusions at intervals along its circumferential direction, and a steam outlet channel is formed between two adjacent heating protrusions. With such a design, the contact area between the heating element and the steam can be increased to enhance the heating rate of the steam.

[0025] 9. An installation boss is provided in the steam generation cavity. The heating element is arranged on the installation boss. A clamping groove is provided on the circumferential side of the installation boss, and a curled edge formed by inward winding is provided at the bottom of the air guide cover. The curled edge is clamped into the clamping groove. With such a design, the heating element can be lifted by a certain height through the installation boss, so that it cannot contact the water at the bottom of the steam generation cavity, thereby avoiding directly heating the water by the heating element and ensuring that the heating element is only used for heating steam. In addition, the installation boss can also be used to fix the air guide cover, and the air guide cover is fixed by the curled edge being clamped into the clamping groove, which is simple and convenient for assembly.

[0026] 10. The water separation cover is made of silica gel or rubber, and the air guide cover is made of metal hardware. With such a design, the air guide cover can support the water separation cover to ensure the smoothness of the steam inlet channel. In addition, it can also prevent the air guide cover from deforming after being heated by the heating element, thus ensuring the structural stability of the air guide cover. Secondly, the heat conduction performance of the water separation cover is much lower than that of the metal hardware, so the temperature of the water separation cover is lower than that of the metal hardware, that is, the water separation cover has a heat insulation effect, avoiding scalding when the user takes the water separation cover from the base and improving the user experience. Finally, it can also make the sealing sleeve and the juice receiving tray achieve soft contact sealing to improve the sealing reliability between the sealing sleeve and the juice receiving tray.

[0027] These features and advantages of the present utility model will be detailedly disclosed in the following specific embodiments and drawings.

Specific Embodiment

[0040] The present utility model provides an electric steamer, including a base and a juice receiving tray carried on the base. The juice receiving tray and the base define a steam generating cavity for generating steam. A heating element, an air guide cover and a water isolation cover which are sequentially sleeved outside the heating element from inside to outside are arranged in the steam generating cavity. The water isolation cover includes an integrally formed cover body and a sealing sleeve. A steam inlet and a steam outlet are arranged on the cover body. The air guide cover is hermetically connected to the cover body and an air inlet channel communicating with the steam inlet is formed therebetween. An air outlet channel is formed between the air guide cover and the heating element. The air outlet channel communicates the air inlet channel with the steam outlet. The sealing sleeve is arranged around the steam outlet and is hermetically connected to the juice receiving tray to guide the steam discharged from the steam outlet above the juice receiving tray. With such a design, by integrally processing and forming the cover body and the sealing sleeve, not only can the assembly steps of the cover body and the sealing sleeve be omitted to improve the assembly efficiency, but also the sealing performance at the connection between the cover body and the sealing sleeve can be ensured to prevent steam from leaking through this place. Thus, all the steam discharged from the steam outlet can flow above the juice receiving tray, thereby ensuring the cooking efficiency.

[0042] Embodiment 1

[0043] As Figures 1 to 9 shown, the electric steam cooker in this embodiment includes a base 100, a juice receiving tray 200, and a steamer assembly 300. The base 100 has a concave cavity 110. The juice receiving tray 200 is placed on the base 100 to cover the concave cavity 110, and the steamer assembly 300 is placed on the juice receiving tray 200. The steamer assembly 300 includes a plurality of steaming cavities 310. An annular partition rib 120 is provided between the bottom wall of the concave cavity 110 and the juice receiving tray 200. The partition rib 120 divides the space between the bottom wall of the concave cavity 110 and the juice receiving tray 200 into a water replenishing cavity 111 and a steam generating cavity 112. The steam generating cavity 112 is located inside the partition rib 120, and the water replenishing cavity 111 is located outside the partition rib 120 and stores water. A water passing hole communicating the steam generating cavity 112 and the water replenishing cavity 111 is provided at the bottom of the partition rib 120, so that the water in the water replenishing cavity 111 flows into the steam generating cavity 112 through the water passing hole. The base 100 further includes a heating plate 400 provided on the bottom wall of the concave cavity 110 and corresponding to the steam generating cavity 112. The heating plate 400 heats the water in the steam generating cavity 112 to make it form steam when heated.

[0044] In the steam generation chamber 112 of this embodiment, a heating element 130 is further provided, as well as a gas guide cover 140 and a water isolation cover 150 that are sequentially sleeved outside the heating element 130 from the inside to the outside. The water isolation cover 150 includes an integrally formed cover body 151 and a sealing sleeve 152. The cover body 151 is provided with a steam inlet 1511 and a steam outlet 1512. The gas guide cover 140 is hermetically connected to the cover body 151, and a steam inlet channel 160 communicating with the steam inlet 1511 is formed therebetween. An outlet steam channel 170 is formed between the gas guide cover 140 and the heating element 130. The outlet steam channel 170 communicates the inlet steam channel 160 with the steam outlet 1512. The sealing sleeve 152 is disposed around the steam outlet 1512 and is hermetically connected to the juice receiving tray 200 to guide the steam discharged from the steam outlet 1512 above the juice receiving tray 200 and flow into each steaming chamber 310 to heat the food in the steaming chamber 310. With such a design, the steam in the steam generation chamber 112 sequentially flows through the inlet steam channel 160 and the outlet steam channel 170 through the steam inlet 1511. During the process of flowing through the outlet steam channel 170, the heating element 130 heats the steam to form superheated steam. The superheated steam is discharged through the steam outlet 1512 and flows above the juice receiving tray 200 under the guidance of the sealing sleeve 152. By integrally processing and forming the cover body 151 and the sealing sleeve 152, not only can the assembly steps of the cover body 151 and the sealing sleeve 152 be omitted to improve the assembly efficiency, but also the sealing performance at the connection between the cover body 151 and the sealing sleeve 152 can be ensured to prevent steam from leaking through this place. As a result, all the steam discharged from the steam outlet 1512 can flow above the juice receiving tray 200, thereby ensuring the cooking efficiency.

[0045] Specifically, the cover body 151 in this embodiment includes a sealing connection portion 1513. The sealing connection portion 1513 is disposed between the steam inlet 1511 and the steam outlet 1512. The gas guide cover 140 is independently processed and formed. The gas guide cover 140 is fixedly fitted with the sealing connection portion 1513 to separate the steam inlet 1511 and the steam outlet 1512. With such a design, the water isolation cover 150 and the gas guide cover 140 can be separately processed and formed to reduce the processing difficulty of the water isolation cover 150 and the gas guide cover 140. At the same time, the two can be prepared from different materials according to needs to increase the diversity of the product. Finally, by fixedly fitting the sealing connection portion 1513 with the gas guide cover 140 to separate the steam inlet 1511 and the steam outlet 1512, it can also prevent the steam entering the cover body 151 from the steam inlet 1511 from flowing to the steam outlet 1512. As a result, the steam can flow along the preset flow path and be discharged through the steam outlet 1512.

[0046] Preferably, the water isolation cover 150 is made of silica gel or rubber, that is, both the cover body 151 and the sealing sleeve 152 are made of silica gel or rubber. With such a design, the processing technology of the water isolation cover 150 can be simplified, and thus the processing difficulty of the water isolation cover 150 can be reduced; while the air guide cover 140 is made of hardware, preferably stainless steel. With such a design, the water isolation cover 150 can be supported by the air guide cover 140 to ensure the smoothness of the steam inlet channel 160; in addition, it can also prevent the air guide cover 140 from deforming after being heated by the heating element 130, thereby ensuring the structural stability of the air guide cover 140; secondly, the heat conduction performance of the water isolation cover 150 is much lower than that of the hardware, so the temperature of the water isolation cover 150 is lower than that of the hardware, that is, the water isolation cover 150 has a heat insulation effect, avoiding scalding when the user takes the water isolation cover 150 from the base 100, and improving the user experience; finally, it can also make the sealing sleeve 152 and the juice receiving tray 200 achieve soft contact sealing to improve the sealing reliability between the sealing sleeve 152 and the juice receiving tray 200.

[0047] The sealing sleeve 152 in this embodiment includes a sealing body 1521 and a sealing skirt 1522. The sealing body 1521 is arranged around the steam outlet 1512. The bottom end of the sealing skirt 1522 is connected to the top of the sealing body 1521. The outer diameter of the sealing skirt 1522 gradually decreases upward. The sealing skirt 1522 can expand and contract relative to the sealing body 1521. A through hole 210 corresponding to the steam outlet 1512 is provided on the juice receiving tray 200. The sealing skirt 1522 abuts against the juice receiving tray 200 for sealing and surrounds the outside of the through hole 210. In this way, the steam discharged from the steam outlet 1512 can be guided above the juice receiving tray 200 through the sealing sleeve 152, avoiding leakage of overheated steam.

[0048] It can be understood that in other embodiments of the present invention, the sealing sleeve can also penetrate through the through hole and be in interference fit with the through hole. With such a design, the steam discharged from the steam outlet can also be guided above the juice receiving tray through the sealing sleeve, avoiding leakage of overheated steam.

[0049] To facilitate the fixed cooperation between the sealing connection part 1513 and the air guide cover 140, in this embodiment, the steam outlet 1512 is arranged at the center position of the top wall of the cover body 151, and the steam inlet 1511 is arranged on the top wall of the cover body 151 and is located on the outer periphery of the steam outlet 1512. By arranging the steam inlet 1511 on the top wall of the cover body 151, the installation height of the steam inlet 1511 can be increased to prevent the water in the steam generation cavity 112 from entering the cover body 151 through the steam inlet 1511, which may cause the heating element 130 to heat the water in the cover body 151 to boil and generate relatively large noise. The sealing connection part 1513 is a flange formed by bending the edge of the steam outlet 1512 inward. A slot 1514 is formed between the sealing connection part 1513 and the top wall of the cover body 151. An opening 141 corresponding to the steam outlet 1512 is arranged on the top wall of the air guide cover 140, and the edge of the opening 141 is inserted into the slot 1514. With such a design, when the air guide cover 140 and the cover body 151 are assembled, the cooperation and fixation between the air guide cover 140 and the sealing connection part 1513 can be realized by inserting the edge of the opening 141 into the slot 1514. Since the sealing connection part 1513 is a flexible part, the fixation of the two is facilitated and the fixation strength is relatively high. In addition, multiple seals can be achieved at the fixation part to improve the sealing performance between the cover body 151 and the air guide cover 140.

[0050] Since the cover body 151 is made of a flexible material such as silica gel or rubber, its structural strength is relatively weak. To enhance the structural strength of the cover body 151, at least one reinforcing rib 1515 is convexly provided on the inner side wall of the cover body 151. With such a design, the structural strength of the cover body 151 can be increased by arranging the reinforcing rib 1515 to ensure the stability of the shape of the cover body 151, and further ensure the smoothness of the steam inlet channel 160.

[0051] In this embodiment, the number of the reinforcing ribs 1515 is at least two. The reinforcing ribs 1515 are rib structures extending vertically. The multiple reinforcing ribs 1515 are circumferentially and spacedly distributed on the inner side wall of the cover body 151. The reinforcing ribs 1515 abut against the outer side surface of the air guide cover 140. The above-mentioned steam inlet channels 160 are formed between two adjacent reinforcing ribs 1515, and the steam inlet 1511 is arranged at a position on the top wall of the cover body between two adjacent reinforcing ribs 1515. With such a design, by the abutment of the reinforcing ribs 1515 against the outer side surface of the air guide cover 140, the support for the cover body 151 can be realized to ensure the stability of the shape of the cover body 151. In addition, by arranging multiple reinforcing ribs 1515, the structural strength of the cover body 151 can be further enhanced to ensure the stability of the shape of the cover body 151, and further ensure the smoothness of each steam inlet channel 160.

[0052] In this embodiment, a plurality of steam inlet holes 142 are provided on the side wall of the air guide cover 140. The steam inlet holes 142 communicate with the steam inlet channel 160 and the steam outlet channel 170. The steam inlet holes 142 are arranged near the bottom of the heating element 130. In this way, the flow path of the steam from entering the cover body 151 to discharging from the steam outlet 1512 can be made more tortuous, thereby extending the flow path, increasing the contact time between the steam and the heating element 130, improving the heating effect of the steam in the steam outlet channel 170, and further ensuring the generation of superheated steam.

[0053] Since two adjacent steam inlet channels 160 are separated by the reinforcing rib 1515, in order to improve the steam inlet efficiency, an air clearance groove 1516 is provided on the reinforcing rib 1515 in this embodiment. The air clearance groove 1516 communicates with the steam inlet channels 160 on both sides of the reinforcing rib 1515. The height position where the steam inlet holes 142 are located corresponds to the height position of at least one air clearance groove 1516, that is, a part of the steam inlet holes 142 are arranged corresponding to the steam inlet channels 160, and another part of the steam inlet holes 142 are arranged corresponding to the air clearance groove 1516 and communicate with it. In this way, the steam inlet volume per unit time of the steam inlet holes 142 can be increased, thereby improving the air intake efficiency and further enhancing the cooking efficiency.

[0054] In order to prevent the steam in the steam inlet channel 160 from leaking out from the bottom of the cover body 151, at least one sealing rib 1517 is convexly provided on the inner side surface of the cover body 151 in this embodiment. The axis of the sealing rib 1517 is coaxially arranged with the axis of the cover body 151. The air guide cover 140 is provided with a steam inlet part communicating with the steam inlet channel 160 and the steam outlet channel 170. The steam inlet holes 142 form the steam inlet part. The sealing rib 1517 is located below the steam inlet part and is in sealing contact with the outer side surface of the air guide cover 140. With such a design, the sealing performance between the cover body 151 and the outer side surface of the air guide cover 140 can be improved to prevent the steam in the steam inlet channel 160 from leaking to the outside of the cover body 151; at the same time, only by sleeving the cover body 151 on the outside of the air guide cover 140 can the sealing rib 1517 be in sealing contact with the air guide cover 140, thereby reducing the assembly difficulty between the air guide cover 140 and the water isolation cover 150.

[0055] In this embodiment, a plurality of radially protruding heating protrusions 131 are arranged at intervals along the circumferential direction of the heating element 130. An outlet channel 170 is formed between two adjacent heating protrusions 131. With such a design, the contact area between the heating element 130 and the steam can be increased to improve the heating rate of the steam.

[0056] Finally, an installation boss 180 is provided in the steam generation chamber 112 in this embodiment. The heating element 130 is arranged on the installation boss 180. An annular card slot 181 is provided on the circumferential side of the installation boss 180. The bottom of the air guide cover 140 is provided with a curled edge 143 formed by inward winding, and the curled edge 143 is snapped into the card slot 181. With such a design, the heating element 130 can be lifted by a certain height through the installation boss 180, so that it cannot contact the water at the bottom of the steam generation chamber 112, thereby avoiding directly heating the water by the heating element 130 and ensuring that the heating element 130 is only used for heating steam. In addition, the installation boss 180 can also be used to fix the air guide cover 140, and the air guide cover 140 is fixed by snapping the curled edge 143 into the card slot 181, which is simple and convenient to assemble.

[0057] It can be understood that in other embodiments of the present invention, the bottom of the water isolation cover abuts and seals against the circumferential side of the installation boss. At this time, the air guide cover can be suspended under the action of the sealing connection part, that is, there is a flow gap between the bottom of the air guide cover and the top surface of the installation boss, and the flow gap communicates with the steam inlet channel and the steam outlet channel; or, the bottom of the air guide cover is provided with a steam inlet hole, and the steam inlet channel and the steam outlet channel are communicated through the steam inlet hole.

[0058] It can be understood that in other embodiments of the present invention, the steam inlet can also be arranged on the side wall of the cover body and close to the top of the cover body.

[0059] It can be understood that in other embodiments of the present invention, the sealing connection part may further include two circles of limiting ribs arranged on the top wall of the cover body and extending downward. The side wall of the air guide cover encloses an opening corresponding to the steam outlet, and the side wall of the air guide cover is inserted between the two circles of limiting ribs. With such a design, the purpose of separating the steam inlet and the steam outlet can also be achieved through the cooperation and fixation of the sealing connection part and the air guide cover.

[0060] It can be understood that in other embodiments of the present invention, the air guide cover is a silica gel part or a rubber part made of the same material as the water isolation cover, and the air guide cover and the water isolation cover are integrally processed.

[0061] In the present invention, those not described can be implemented by adopting or referring to the existing technologies.

[0062] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
