[0001] The utility model relates to the field of steamers, in particular to a water storage tank and a multifunctional steamer. Background Art

[0002] At present, the structure of a steamer mainly includes a steam generator, a water pump, and a water storage tank. The water outlet end of the water pump is connected to the steam generator, and the water inlet end of the water pump extends into the water storage tank through a pipeline and is communicated with the bottom of the inner cavity of the water storage tank. Through the operation of the water pump, the clear water in the inner cavity of the water storage tank is conveyed into the steam generator for heating to form steam and discharged into the steaming cavity of the steamer to steam food. During actual use, to avoid the pipe orifice adsorbing the bottom surface of the water storage tank and causing blockage, there is a certain distance between the pipe orifice and the bottom surface of the water storage tank. Therefore, it is inevitable that the water in the water storage tank cannot be completely sucked out, resulting in waste, and the accumulated water will cause scale problems in the water storage tank. Therefore, the water storage tank of some steamers is connected to the steam generator by the principle of a communicating vessel to ensure that the clear water can be fully utilized. However, this method limits the water outlet of the water storage tank to its bottom surface, restricting the relative position of the water storage tank during the design of the steamer and making it unable to be freely arranged better, which will affect the appearance design of the steamer. Therefore, the applicant provides a new steamer solution through the improvement and perfection of the existing technology for consumers to choose and use. Summary of the Invention

[0027] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] As Figures 1 to 8 shown, a water storage tank includes a tank main body 1. A water storage cavity 101 is provided inside the tank main body 1. A water inlet suction cup 2 is provided inside the tank main body 1 and abuts against the bottom of the water storage cavity 101. A straw 3 is provided on the water inlet suction cup 2 and extends outside the tank main body 1. A plurality of water inlet channels 201 that converge into the straw 3 are formed on the bottom surface of the water inlet suction cup 2. A water absorption channel 4 is formed by surrounding between the water inlet channels 201 and the bottom of the water storage cavity 101.

[0029] In a traditional water storage tank, in order to make the most of the water in the water storage tank, the pipeline can only be infinitely close to the inner bottom surface of the water storage tank, and the clear water is sucked away by negative pressure. However, the closer the pipeline is to the inner bottom surface of the water storage tank, the smaller the water absorption gap between the two, which affects the water absorption flow rate and reduces the water absorption efficiency.

[0030] Therefore, the water suction cup 2 in this water storage tank can reduce the flow cross-sectional area through the water absorption channel 4, increasing the negative pressure in the water absorption channel 4. And the water absorption channel 4 is composed of the inner bottom surface of the water storage tank 4, ensuring that even when there is a very small amount of water left in the water storage tank, the water can still flow into the water absorption channel 4 and the water in the water storage tank can be sucked clean through a relatively large negative pressure, improving the utilization efficiency.

[0031] The bottom of the water storage cavity 101 is inclined downward from its edge towards the central position, and the water inlet suction cup 2 is abutted against the central position of the bottom of the water storage cavity 101; this structure ensures that the water in the water storage tank converges towards the central position, facilitating the water inlet suction cup to suck the water in the water storage tank.

[0032] The suction pipe 3 extends upward from the central position of the water inlet suction cup 2, and several water inlet through grooves 201 are evenly distributed along the radial direction on the bottom surface of the water inlet suction cup 2; it can suck the water in the surrounding directions of the water storage cavity 101, improving the water suction efficiency, and reducing mutual interference during convergence.

[0033] The water tank main body 1 includes a box body 11 and a box cover 12. Several sucker pressing columns 121 extend downward from the bottom surface of the box cover 12. After the box cover 12 is connected to the box body 11, the several sucker pressing columns 121 press against the top surface of the water inlet suction cup 2.

[0034] In this embodiment, positioning sleeves 202 are provided on the top surface of the water inlet suction cup 2 corresponding to the sucker pressing columns 121. By inserting the sucker pressing columns 121 into the positioning sleeves 202 and pressing against the top surface of the water inlet suction cup 2, the water inlet suction cup 2 is positioned and abutted against the inner bottom surface of the box body 11;

[0035] This structure ensures that the water inlet suction cup 2 can be tightly pressed against the inner bottom surface of the box body 11, ensuring that a water suction channel 4 with a relatively small flow cross-sectional area can be formed between the water inlet through grooves 201 and the inner bottom surface of the box body 11, improving the water suction efficiency and water utilization efficiency; the cooperation of the sucker pressing columns 121 and the positioning sleeves 202 fixes the position of the water inlet suction cup 2, preventing the water inlet suction cup 2 from sliding horizontally on the inner bottom surface of the box body 11.

[0036] A convex stop 111 is provided along the top edge of the box body 11, and a concave stop 122 is provided at the edge of the box cover 12 that mates with the convex stop 111. The box body 11 and the box cover 12 are connected into one body by ultrasonic welding between the concave stop 122 and the convex stop 111, and a pull cloth 13 is clamped at the front end of the box cover 12;

[0037] The convex stop 111 and the concave stop 122 are engaged with each other, which can improve the sealing performance between the box body 11 and the box cover 12. Then, using ultrasonic welding, the box cover 12 is fixed on the box body 11, forming a relatively enclosed water storage cavity 101 in the water tank main body 1, reducing the leakage condition, and the pull cloth 13 facilitates pulling out the water tank main body 1.

[0038] When the pull cloth 13 is installed, it is mainly fastened by screws, such as Figure 10As shown, an upper connection hole 131 is provided at the rear end of the cloth 13, and a lower connection hole 121 corresponding to the upper connection hole 131 is provided on the box cover 12. The cloth 13 is fastened to the box cover 12 by screws passing through the upper connection hole 131 and the lower connection hole 121. Moreover, the water tank main body 1 further includes a water tank cover 14. The water tank cover 14 is attached to the front side of the box body 11. A pressing plate 141 extends from the rear side of the water tank cover 14, and the rear end of the cloth 13 is clamped between the pressing plate 141 and the box cover 12. The front end of the cloth 13 extends out in front of the water tank cover 14, and finally the pressing plate 141 is fixedly connected to the box cover 12 by ultrasonic welding.

[0039] A water filling port 102 is provided on the water tank main body 1, and a sealing plug 5 for opening or sealing the water filling port 102 is installed on the water tank main body 1; since the box cover 12 is encapsulated on the box body 11, it is necessary to additionally provide a water filling port 102 to facilitate the user to fill the water storage tank with water, and then use the sealing plug 5 to seal the water filling port 102 after filling the water.

[0040] An assembly port is provided on the rear wall of the box body 11, and a water outlet valve 15 is installed in the assembly port. The water inlet end of the water outlet valve 15 is connected to the suction pipe 3 through a pipe 7; since the water storage tank does not need to use the principle of communicating vessels to drain the water in the water storage tank, the position of the water outlet valve 15 does not need to be close to the bottom. After the water storage tank is installed in place, the water outlet valve 15 can be opened by a pushing structure, so that the water pump 85 can pump water from the water storage cavity 101.

[0041] A multifunctional steamer includes a steamer main body 8. An installation cavity 801 is provided in the steamer main body 8, and the above-structured water storage tank is installed in the installation cavity 801 in a push-pull manner.

[0042] An induction member 9 is provided on the rear wall of the water tank main body 1, and a position sensor 10 connected in series to the pumping circuit is provided on the steamer main body 8. After the water tank main body 1 is installed in place, the induction member 9 and the position sensor 10 are inductively matched to connect the pumping circuit;

[0043] In this embodiment, the induction member 9 is the rear wall of the water tank main body 1, and the position sensor 10 is a microswitch. The microswitch cooperates with the rear wall of the water tank main body 1 to ensure that the pumping circuit or other working circuits can be connected only after the water storage tank is installed in place;

[0044] In other embodiments, the induction member 9 can also be a ferromagnetic block, and the position sensor 10 is a magnetic control switch.

[0045] The steamer main body 8 includes a main body housing 81. Three side wall plates 811 extend from the main body housing 81. A top plate 82 is assembled and connected between the three side wall plates 811. The top plate 82 and the three side wall plates 811 jointly enclose an installation cavity 801;

[0046] On the rear side of the bottom surface of the top plate 82, there extends an upper and lower limiting rib 821 that gradually rises from front to back, and on the left and right sides of the top plate 82, there extend left and right limiting plates 822 with inclined guiding surfaces 823;

[0047] The upper and lower limiting rib 821 and the left and right limiting plates 822 can clamp the water storage tank vertically and horizontally.

[0048] In addition, a steam cooking cavity 802 that can be opened or closed and a steam nozzle 83 communicating with the steam cooking cavity 802 are further provided in the steamer main body 8. A steam generator 84 and a water pump 85 are also installed in the steamer main body 8. The water inlet end of the water pump 85 is connected to the water outlet valve 15, the water outlet end of the water pump 85 is connected to the water inlet end of the steam generator 84, and the steam outlet end of the steam generator 84 is connected to the steam nozzle 83.

[0049] The steam nozzle 83 is detachably connected to the steamer main body 8 and is disposed in the steam cooking cavity 802. As Figure 9 shown, it mainly includes a jet straight pipe 831. Two or more jet ports 832 are provided in the jet straight pipe 831 along the height direction, and the jet ports 832 face the direction of the steam cooking cavity 802. The steam nozzle 83 with this structure can play a role in preventing scale.
