[0038] Embodiment 1

[0039] like Figures 1 to 6 As shown, the electric steamer in this embodiment includes a base 100 and a water tank 200, the base 100 includes a water pump (not shown in the figure), a steam generating tank 110, and a heating element 120, wherein the base 100 includes a bottom plate 130 and an upper cover 140 connected with the bottom plate 130 to form a cavity 300, the top wall of the upper cover 140 forms the top wall of the base, the top wall of the upper cover 140 is provided with the above-mentioned steam generating tank 110, and the water pump and the heating element 120 are both installed in the cavity 300, wherein the heating element 120 is used to heat The water in the steam generating tank 110 and the bottom wall of the steam generating tank 110 corresponding to the position of the heating element 120 form a heating zone 111. The side wall of the steam generating tank is provided with a water outlet 112. The water pump connects the water tank 200 and the water outlet 112. In addition, the electric steamer also includes a water retaining rib 400 at least provided between the water outlet 112 and the heating zone 111. The water retaining rib 400 is used to prevent the water from the water outlet 112 from being directly sprayed into the heating zone 111, and the area between the water retaining rib 400 and the water outlet 112 is connected to the heating zone 111.

[0040] In this way, after the water pump draws out the water in the water tank 200 and sprays it out through the water outlet 112, the sprayed water can fall into the bottom wall of the steam generating groove and into the area between the water outlet 112 and the heating zone 111 under the obstruction of the water retaining rib 400. Since the area between the water retaining rib 400 and the water outlet 112 is connected to the heating zone 111, the water in the area between the water outlet 112 and the heating zone 111 will flow into the heating zone 111. Compared with the prior art of directly spraying cold water into the heating zone, the technical solution of this embodiment can reduce the problem of suspension of steam generation in the heating zone 111 due to the instantaneous spraying of cold water, that is, the heating zone 111 can continuously generate steam, thereby ensuring the heating efficiency of the electric steamer.

[0041] Specifically, in this embodiment, a sink 141 is provided at the center of the top wall of the upper cover 140, and a mounting opening 142 and a metal plate 143 for shielding the mounting opening 142 are provided at the bottom wall of the sink. The diameter of the mounting opening 142 is smaller than the outer diameter of the bottom wall of the sink. The metal plate 143 and the sink 141 surround the steam generating tank 110, that is, the portion of the metal plate 143 corresponding to the mounting opening 142 and the portion of the bottom wall of the sink where the mounting opening is not provided together form the bottom wall of the steam generating tank 110, and the side wall of the sink forms the side wall of the steam generating tank. The heating element 120 includes a disk 121 and a heating pipe 122 provided on the bottom surface of the disk 121. The top surface of the disk 121 contacts the metal plate 143, so that the heat generated by the heating pipe 122 is transferred to the metal plate 143 through the disk 121, thereby heating the steam generating tank 110. It can be seen that the portion of the metal plate 143 corresponding to the installation opening 142 is the portion of the bottom wall of the steam generating tank corresponding to the heating element 120 , that is, the area of ​​the metal plate 143 corresponding to the installation opening 142 forms the above-mentioned heating zone 111 .

[0042] The water retaining rib 400 in this embodiment surrounds the outside of the heating zone 111, that is, the water retaining rib 400 is an annular rib, and a cold water transition zone 113 is formed between the water retaining rib 400 and the side wall of the steam generating groove. The water retaining rib 400 is provided with a notch 410 connecting the heating zone 111 and the cold water transition zone 113. The notch 410 extends from the upper end of the water retaining rib 400 to the bottom end of the water retaining rib 400. The notch 410 and the water outlet 112 are staggered, that is, the projection of the notch 410 along the radial direction of the bottom wall of the sink and projected onto the side wall of the steam generating groove does not overlap with the water outlet 112. Such a design can improve the blocking effect of the water retaining rib 400 on the water in the cold water transition zone 113, so that the water in the cold water transition zone 113 can only enter the heating zone 111 through the gap 410, thereby further reducing the amount of water flowing into the heating zone 111 per unit time, thereby reducing the impact of cold water on the water temperature in the heating zone 111, and ensuring that the heating zone 111 can continue to generate steam; in addition, the annular water retaining rib 400 can also effectively block the steam to prevent it from diffusing outward, thereby allowing a large amount of steam to enter the steamer assembly above, thereby further improving the heating efficiency.

[0043] In order to avoid the situation that the steam generation is temporarily stopped due to the lack of water in the heating zone 111, a plurality of notches 410 are provided at intervals in the circumferential direction on the water retaining rib 400 in this embodiment. Such a design enables the water in the cold water transition zone 113 to flow into the heating zone 111 in time to replenish the water in the heating zone 111, thereby avoiding the situation that the steam generation is temporarily stopped due to the lack of water in the heating zone 111; at the same time, the plurality of notches 410 can also disperse the cold water entering the heating zone 111, so as to further reduce the influence of the cold water on the water temperature in the heating zone 111.

[0044] The water retaining rib 400 in this embodiment is arranged on the bottom wall of the steam generating tank 110. Preferably, the water retaining rib 400 and the top wall of the upper cover are integrally formed, and the inner side surface of the water retaining rib 400 is flush with the hole wall of the installation opening 142, and the top of the water retaining rib 400 is higher than the highest point of the water outlet 112. With such a design, the assembly of the water retaining rib 400 and the upper cover 140 can be omitted, thereby improving the assembly efficiency of the base 100.

[0045] In addition, in this embodiment, the top surface of the metal plate 143 is lower than the portion of the bottom wall of the sink where the mounting opening 142 is not provided, so that the heating zone 111 is lower than the cold water transition zone 113. Such a design can prevent the water in the heating zone 111 from flowing out to the cold water transition zone 113, thereby ensuring the amount of water in the heating zone 111, so that the heating zone 111 can continuously generate steam.

[0046] Furthermore, the electric steamer in this embodiment further comprises a juice receiving tray 500 mounted on the base 100, the portion of the juice receiving tray 500 corresponding to the steam generating groove 110 is arched upward to form a boss 510, the boss 510 cooperates with the steam generating groove 110 to form a steam generating chamber, and a steam outlet 511 is provided at the top of the boss 510. With such a design, a juice receiving groove 520 can be formed between the boss 510 and the side wall of the juice receiving tray, and since the steam outlet 511 is provided at the top of the boss 510, water in the juice receiving groove 520 can be prevented from dripping into the steam generating groove 110 through the steam outlet 511.

[0047] Finally, in this embodiment, the top wall of the upper cover is also provided with a mounting groove 144, the bottom of the water tank 200 is inserted into the mounting groove 144, a water inlet joint connected to the water pump is provided on the bottom wall of the mounting groove 144, and a drain port is provided at the bottom of the water tank 200. After the bottom of the water tank 200 is inserted into the mounting groove 144, the drain port is connected to the water inlet joint. Such a design can facilitate the disassembly and assembly of the water tank 200, and further facilitate the water tank 200 to be replenished with water or cleaned separately.

[0048] It is understandable that in other embodiments of the present invention, the water retaining rib can also be an arc-shaped rib, the center of which is the center of the bottom wall of the sink, and the water retaining rib is radially along the bottom wall of the sink and projected onto the side wall of the steam generator groove to cover the water outlet, thereby preventing the water from the water outlet from being directly sprayed into the heating area. Therefore, the water retaining rib is an arc-shaped rib, which can not only reduce the material cost of the water retaining rib, thereby reducing the manufacturing cost of the product; it can also naturally realize that the area between the water retaining rib and the water outlet is connected to the heating area, and the overall structure is relatively simple.

[0049] Embodiment 2

[0050] Compared with the first embodiment, the present embodiment is different in that the water retaining rib is arranged on the juice receiving tray and extends downward, and the bottom end of the water retaining rib is lower than the water outlet, so that the water retaining rib prevents the water from the water outlet from spraying directly into the heating zone.

[0051] Specifically, the water retaining rib is an annular rib that surrounds the outside of the heating zone and is integrally formed with the juice receiving tray. The bottom end of the annular rib is lower than the water outlet, and the bottom end of the annular rib abuts against a portion of the bottom wall of the sink where no mounting opening is provided. A cold water transition zone is formed between the water retaining rib and the side wall of the steam generating groove. A plurality of notches are circumferentially spaced at the bottom end of the water retaining rib, and the notches connect the cold water transition zone and the heating zone, and the notches are staggered from the water outlet. Such a design can also enable the water retaining rib to prevent water from the water outlet from being directly sprayed into the heating zone, and at the same time, can also enable water in the area between the water outlet and the heating zone to flow into the heating zone, so as to reduce the problem of suspension of steam generation in the heating zone due to the instantaneous spraying of cold water, so that the heating zone can continuously generate steam, thereby ensuring the heating efficiency of the electric steamer.

[0052] It can be understood that in other embodiments of the present invention, when the bottom end of the annular rib is lower than the water outlet, the bottom end of the annular rib and the portion of the bottom wall of the sump where no installation opening is provided can also be spaced apart to form a flow gap, and the flow gap connects the cold water transition zone and the heating zone. Such a design can also enable the water retaining rib to achieve the purpose of preventing water from the water outlet from being sprayed directly into the heating zone.

[0053] It can be understood that in other embodiments of the present invention, the water retaining rib can also be an arc-shaped rib integrally formed with the juice collecting plate, the bottom end of the arc-shaped rib is against the portion of the bottom wall of the sink where no installation opening is provided, the center of the arc-shaped rib is the center of the bottom wall of the sink, and the water retaining rib is radially along the bottom wall of the sink and projected onto the side wall of the steam generating groove to cover the water outlet, thereby preventing the water from the water outlet from being directly sprayed into the heating zone.

[0054] Embodiment 3

[0055] Compared with the first and second embodiments, the difference of this embodiment is that: the water retaining bar includes a first water retaining bar and a second water retaining bar sleeved outside the first water retaining bar, the second water retaining bar is arranged on the juice receiving plate and extends downward, a flow gap is arranged between the bottom end of the second water retaining bar and the bottom wall of the steam generating tank, the first water retaining bar is arranged on the bottom wall of the steam generating tank and extends upward, the top end of the first water retaining bar is higher than the bottom end of the second water retaining bar, and a notch is arranged at the bottom end of the first water retaining bar, and the projection of the notch along the radial direction of the bottom wall of the sink and projected onto the side wall of the steam generating tank does not overlap with the water outlet. Such a design can enhance the blocking effect of the water retaining bar on the water sprayed out of the water outlet, and at the same time, the area between the second water retaining bar and the water outlet can be connected with the heating area through the flow gap and the notch; in addition, it is only necessary to meet the requirement that the top end of the first water retaining bar is higher than the bottom end of the second water retaining bar, and there is no need to set the height of the first water retaining bar and the second water retaining bar with reference to the water outlet, thereby reducing the height dimension requirements of the first water retaining bar and the second water retaining bar.
