[0001] The present application relates to the technical field of dishwashers, and in particular to a water tank structure of a dishwasher and a dishwasher. Background Art

[0002] With the development of society, consumers have higher and higher requirements for dishwashers. In order to meet consumers' higher and higher performance requirements for dishwashers, more and more manufacturers use water tank technology on dishwashers to improve the performance parameters of dishwashers. The water tanks on the market now have two functions: 1. Clean water tanks, which use the principle of heat absorption to increase the water temperature of the water discharged into the inner tank of the dishwasher and reduce the energy consumption required for heating; 2. Waste water tanks, which use the hot waste water to be discharged after the dishwasher is heated to release heat to the inside of the dishwasher, and reduce energy consumption by recycling heat. Utility Model Content

[0003] The object of the present invention is to provide a water tank structure of a dishwasher and the dishwasher, wherein the structure can combine the functions of a clean water tank and a waste water tank to improve the performance parameters of the dishwasher.

[0004] In a first aspect, a water tank structure of a dishwasher of the present application comprises:

[0005] A water tank, wherein a water storage cavity is formed inside the water tank; a water inlet channel, a drainage channel and a water purification channel are provided on the water tank; wherein the water inlet channel is connected to an external water source, and the drainage channel is selectively connected to the washing cavity; the water inlet channel, the water purification channel, the water storage cavity and the drainage channel are connected in sequence to form a transmission path for purified water.

[0006] The water tank structure of the dishwasher disclosed in the present application is provided with a water inlet channel and a drainage channel on the water tank, and a water storage cavity is formed inside the water tank, and the water inlet channel, the water purification channel, the water storage cavity and the drainage channel are connected in sequence; the drainage channel can be selectively connected with the washing cavity of the inner tank of the dishwasher, and optionally, the drainage channel can be selectively connected with the washing cavity through a control valve; when the control valve is in a closed state, the external water source passes through the water purification channel and the water storage cavity in sequence, and is finally stored in the water storage cavity, and the water tank is used as a purification water storage tank at this time ... After opening, the clean water in the water storage chamber enters the washing chamber through the drainage channel as washing water; in addition, when the dishwasher completes washing, the waste water in the washing chamber can be transported to the water storage chamber through the drainage channel after the control valve is opened. At this time, the water storage tank is used as a waste water storage tank after the control valve is closed. At this time, the heat of the waste water can be transferred to the inside of the dishwasher, and energy consumption is reduced by recycling heat. Through the above structure, the water storage tank of the present application can have both clean water storage and waste water storage functions to meet the increasingly high performance requirements of dishwashers.

[0007] In one of the embodiments, an overflow channel and a first mounting port are further provided on the water tank, the first mounting port is connected to the washing chamber, and the water storage chamber is connected to the first mounting port through the overflow channel; wherein the height of the overflow channel on the water tank is higher than the height of the first mounting port on the water tank.

[0008] The water tank structure of the dishwasher in the above embodiment further defines that an overflow channel and a first installation port are provided in the water tank, wherein the water storage chamber, the overflow channel, the first installation port and the washing chamber of the inner tank of the dishwasher are connected in sequence; the height of the overflow channel on the water tank is higher than the height of the first installation port on the water tank, when the clean water or waste water in the water storage chamber exceeds the warning line, that is, the liquid overflowing the overflow channel is transported to the washing chamber through the overflow channel and the first installation port in sequence, thereby avoiding an explosion in the water tank due to excessive water pressure.

[0009] In one of the embodiments, at least a portion of the height of the clean water channel on the water tank is higher than the height of the overflow channel on the water tank.

[0010] The water tank structure of the dishwasher in the above embodiment further defines that the height of at least part of the water inlet channel on the water tank is higher than the height of the overflow channel on the water tank. When the liquid in the water storage chamber is too high, the liquid overflowing the overflow channel is first transmitted to the washing chamber of the inner tank of the dishwasher through the overflow channel and the first mounting port in sequence, thereby avoiding the problem of backflow caused by the liquid entering the clean water channel before reaching the overflow channel due to the fact that the clean water channel is entirely lower than the height of the overflow channel in the water tank.

[0011] In one of the embodiments, a common channel and an air pressure balance channel are also provided on the water tank, the overflow channel is connected with the first installation port through the common channel, one end of the air pressure balance channel is connected with the common channel, and the other end of the air pressure balance channel is connected with the outside atmosphere.

[0012] The water tank structure of the dishwasher in the above embodiment further defines that a common channel and an air pressure balance channel are provided in the water tank, wherein the overflow channel, the common channel and the first installation port are connected in sequence, and the common channel is also connected to the air pressure balance channel connected to the external atmosphere; by providing the air pressure balance channel, the washing chamber can be connected to the external atmosphere through the first installation port, the common channel and the air pressure balance channel in sequence, thereby preventing the washing chamber and / or the water tank from bursting due to excessive internal pressure. At the same time, in the process of the water tank outputting liquid to the washing chamber, the internal pressure of the water tank is lower than the external atmosphere. The pressure of the water storage chamber can be adjusted in time by connecting the air pressure balance channel to the water storage chamber, thereby ensuring the pressure balance in the water storage chamber and allowing liquid transportation to proceed normally.

[0013] In one of the embodiments, the common channel is distributed from top to bottom in the height direction of the water tank, the upper end of the common channel is connected to the overflow channel, the lower end of the common channel is connected to the first installation port, and a plurality of baffles are arranged in the common channel, and the plurality of baffles are staggered on both sides of the common channel.

[0014] The water tank structure of the dishwasher in the above embodiment further defines that the common channel is located between the overflow channel and the first installation port, and the liquid in the water storage chamber that overflows the overflow channel enters the first installation port through the common channel, and a plurality of baffles are arranged in the common channel. Specifically, the plurality of baffles are staggered on both sides of the common channel, and the baffles are arranged at an angle and the inclination direction is toward the first installation port. The liquid entering the common channel is slowed down by the plurality of baffles, so that the liquid enters the first installation port smoothly, thereby avoiding the large impact force caused by the fast water flow speed, which causes part of the liquid to enter the air pressure balance channel.

[0015] In one embodiment, an opening is provided at the upper end of the common channel, and the common channel is connected with the air pressure balance channel through the opening. An air inlet is formed at one end of the air pressure balance channel away from the opening and toward the first mounting port. The air inlet, the air pressure balance channel and the opening are connected in sequence, and the air pressure balance channel is connected with the external atmosphere through the air inlet. The height of the air pressure balance channel on the water tank is higher than the height of the first mounting port on the water tank.

[0016] The water tank structure of the dishwasher in the above embodiment further defines that the height of the air pressure balance channel on the water tank is higher than the height of the first installation port on the water tank. Specifically, the upper end of the air pressure balance channel is connected to the opening on the common channel, and the lower end of the air pressure balance channel is formed with the air inlet for communicating with the outside atmosphere. Based on the above structure, the pressure in the water tank can be effectively balanced to ensure normal water flow and drainage operation and prevent backflow. Specifically, setting the air pressure balance channel at a position higher than the first installation port can effectively prevent air from entering the overflow channel or the first installation port. When water flows from the first installation port or the drainage channel below, the air will be squeezed and discharged. However, if the air pressure balance channel is at the same height as the first installation port, when the water in the water tank flows out, the air may be sucked into the overflow channel or the first installation port to form an air bag, thereby affecting the smooth flow of water.

[0017] In one of the embodiments, a condensation channel is further provided on the water storage tank, one end of the condensation channel is connected to the air pressure balance channel, and the other end of the condensation channel is connected to the first installation port.

[0018] The water tank structure of the dishwasher in the above embodiment further defines that the water tank is provided with a condensation channel, and the water vapor generated in the washing chamber can condense in the condensation channel to prevent the water vapor from being discharged from the air inlet and burning the user.

[0019] In one of the embodiments, the drainage channel is selectively connected to the washing chamber through a control valve.

[0020] The water tank structure of the dishwasher in the above-mentioned embodiment further defines that the drainage channel is selectively connected to the washing chamber through a control valve; the control valve may be a solenoid valve or a manual valve. Preferably, the control valve in this embodiment is a solenoid valve, which can automatically control the opening or closing of the solenoid valve according to the user's command signal or the dishwasher executing a washing program. Through the coordination of the water inlet channel, the drainage channel, the water storage chamber and the solenoid valve, a common water inlet and outlet channel that can be controlled by the solenoid valve is formed, thereby enabling a single water tank to realize two functional modes: clean water storage and waste water storage.

[0021] In one embodiment, the water storage tank includes a front shell and a rear shell, the front shell and the rear shell enclose the water storage cavity, and the front shell and the rear shell are detachably connected.

[0022] In one embodiment, the water tank is flat.

[0023] In a second aspect, the present application provides a dishwasher, comprising:

[0024] A water tank structure as in any of the above;

[0025] The inner liner, the water storage tank is arranged on the side of the inner liner, the inner liner is connected to the water storage tank through a fixing nut, the fixing nut is provided with a plurality of through holes, and the water storage cavity is connected with the washing cavity formed by the inner liner through the plurality of through holes.

[0026] The present application provides a dishwasher, wherein the water tank is fixed on the side of the inner tank by a fixing nut. Specifically, the inner tank is provided with a second mounting port connected to the washing chamber, and a thread matching the fixing nut is formed on the first mounting port of the water storage bottle. The fixing nut partially passes through the second mounting port and is threadedly connected to the first mounting port. At the same time, since a plurality of through holes are provided on the fixing nut, the washing chamber can be connected to the first mounting port through these through holes. Based on the above-mentioned water tank structure, it can have two functional modes of clean water storage and waste water storage, so that the hot waste water to be discharged after being heated by the dishwasher is stored in the water tank to release heat to the inside of the dishwasher, and energy consumption is reduced by heat recovery to meet the increasingly high performance requirements for dishwashers.

At the same time, in the process of the water tank 10 outputting liquid to the washing chamber 201, the internal pressure of the water tank 10 is lower than the external atmosphere. The pressure of the water storage chamber 101 can be adjusted in time by connecting with the water storage chamber 101 through the air pressure balance channel 70, ensuring the pressure balance in the water storage chamber 101, thereby allowing the liquid to be transported normally.

[0054] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: the common channel 60 is distributed from top to bottom in the height direction of the water tank 10, the upper end of the common channel 60 is connected to the overflow channel 50, the lower end of the common channel 60 is connected to the first installation port 102, and a plurality of baffle plates 61 are arranged in the common channel 60, and the plurality of baffle plates 61 are staggered on both sides of the common channel 60.
