Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dishwashers, in particular, to a water storage device for a dishwasher, a dishwasher and a control method thereof. BACKGROUND

[0002] With the improvement of living standards, consumers have higher and higher requirements for the quality of life, and thus have higher and higher requirements for the quality, performance, humanization of use, and intelligentization of operation of products. As an excellent product, dishwashers have gradually entered people's lives.

[0003] In the working process of the dishwasher, water needs to be heated to meet the cleaning degree of the tableware. However, the heated washing water is directly discharged after the washing is completed, and the heat is not recycled, causing waste of energy. Moreover, the heating process of the washing water needs to be performed in the subsequent washing process, increasing the energy consumption. Therefore, some existing dishwashers propose a scheme of absorbing the heat in the previously heated water to heat the water for the subsequent washing process, so as to realize the recycling of energy and achieve the purpose of energy saving.

[0004] In order to realize the purpose of recycling the heat of the washing water of the dishwasher, an existing dishwasher uses a water storage container on the side of the inner tank, and an electromagnetic valve is used to selectively inject water into the inner tank or the water storage container. In the first stage of washing, tap water passes through a softener, and a switching valve controls the water to directly enter the inner tank. When the required water inflow is reached, the switching valve controls the water to be injected into the water storage container. The water in the water storage container can absorb the heat emitted by the inner tank in the first heating and washing stage of the dishwasher. In the second stage of washing, tap water is directly injected into the inner tank through a valve to rinse the tableware. In the third stage of washing, because the rinsing water needs to be heated, the valve controls part or all of the water in the water storage container to be injected into the inner tank, which has been heated by the heat emitted by the inner tank, so as to save the energy consumption of the dishwasher.

[0005] Although the above scheme solves the recycling of the heat of the dishwasher and achieves the purpose of energy saving, because the water inflow mode is different in each stage, the corresponding water inflow path and the corresponding control valve need to be designed for each washing stage. Therefore, the design of the water inflow path is complex, more control valves are used, the assembly is complex, and the cost is high.

DETAILED DESCRIPTION

[0043] The following describes in detail a dishwasher water storage device, a dishwasher and a control method thereof according to the present invention with reference to the accompanying drawings:

[0044] like Figs. 1-3 As shown, this embodiment provides a water storage device for a dishwasher, including a shell 1, wherein the shell 1 has a first chamber 14 and a second chamber 15; the shell 1 has a water inlet 2 and a first water outlet 3 connected to the first chamber 14, and a second water outlet 4 connected to the second chamber 15, the first chamber 14 has an overflow port, and the second chamber 15 is connected to the overflow port of the first chamber.

[0045] The dishwasher water storage device of this embodiment has a first chamber 14 and a second chamber 15 that are interconnected.

[0046] When water needs to be directly fed into the inner tank of the dishwasher, the first water outlet 3 is opened, and the water in the water inlet pipe enters the first chamber 14 through the water inlet 2, and then is directly discharged into the inner tank of the dishwasher through the first water outlet 3 of the first chamber 14.

[0047] When water needs to be stored to absorb heat during the washing process, the first water outlet 3 and the second water outlet 4 are both closed, and the water in the water inlet pipe enters the first chamber 14 through the water inlet 2 and is stored.

[0048] When water heated by recovered heat is stored in the first chamber 14, when the stored water needs to be discharged into the inner tank, the first water outlet 3 can be opened. When cold water needs to be added to the inner tank, the first water outlet 3 remains closed and the second water outlet 4 is opened. The water inlet 2 of the water inlet pipe enters the first chamber 14 and overflows into the second chamber 15 through the overflow port, and is discharged into the inner tank through the second water outlet 4 of the second chamber.

[0049] In summary, the dishwasher water storage device of this embodiment has the following beneficial effects:

[0050] (1) The dishwasher water storage device of this embodiment allows for direct water intake into the inner tank, storing water for heat recovery. It can also control the discharge of heat recovery water into the inner tank, or continue to discharge cold water into the inner tank, depending on the needs of the washing process. This dishwasher water storage device can meet various water inlet requirements for dishwashers. Furthermore, the dishwasher water storage device incorporates a single-inlet, two-outlet water circuit, greatly simplifying waterway connections. Furthermore, a control valve only needs to be installed at the first water outlet 3, eliminating the need for a control valve at the water inlet 2. This reduces the number of control valves, simplifies assembly, and reduces manufacturing costs.

[0051] (2) The water storage device for the dishwasher of this embodiment can store water in the first chamber 14, absorb the heat emitted by the inner tank during the heating and washing process, and be heated, and then used to heat water for the subsequent washing process, thereby realizing heat recovery and utilization, reducing the energy consumption of the dishwasher, reducing the power consumption of the dishwasher, and reducing the user's usage cost.

[0052] In order to separate the first chamber 14 and the second chamber 15 that are interconnected inside the shell 1, the shell described in this embodiment has a hollow chamber inside, and a first partition plate 10 is arranged in the hollow chamber; the lower end of the first partition plate 10 is connected to the bottom wall of the hollow chamber, and the upper end is spaced apart from the top wall of the hollow chamber, dividing the hollow chamber into the first chamber 14 and the second chamber 15 that are interconnected at the upper part; the first water outlet 3 is arranged at the bottom of the first chamber 14, and the second water outlet 4 is arranged at the bottom of the second chamber 15.

[0053] In this embodiment, a first partition plate 10 is used to separate a first chamber 14 and a second chamber 15, which are interconnected at the top. The upper opening of the first chamber 14 serves as an overflow port. When the first chamber 14 is filled with water, further water flowing into the first chamber 14 will overflow through the upper opening into the second chamber 15. The first partition plate 10 of this embodiment can be integrally formed with the housing, resulting in a simple overall structure for the dishwasher water storage device, making it easy to manufacture and extremely cost-effective.

[0054] Furthermore, the water inlet 2 described in this embodiment is arranged at the bottom of the hollow chamber, and the hollow chamber has a water inlet channel connecting the water inlet 2 and the first chamber 14. The water inlet channel is used to guide the water from the bottom water inlet 2 to the upper opening of the first chamber 14 and enter the interior of the first chamber 14.

[0055] As an implementation of this embodiment, a second partition plate 13 is arranged in the hollow chamber described in this embodiment, and the second partition plate 13 is located between the first partition plate 10 and the inner wall of the hollow chamber; the first partition plate 10 and the inner wall of the hollow chamber together form a first chamber 14, the first partition plate 10, the second partition plate 13 and the inner wall of the hollow chamber together form a second chamber 15, and the second partition plate 13 and the inner wall of the hollow chamber together form a water inlet channel extending from the bottom water inlet 2 to the upper open end of the first chamber 14.

[0056] Specifically, the shell 1 described in this embodiment includes a bottom wall, a top wall, and a side wall whose two ends are respectively connected to the bottom wall and the top wall and surround the periphery. The bottom wall, top wall and side walls together form the hollow chamber; the second partition plate 13 includes a first plate section 11 extending along the side wall direction and a second plate section 12 extending along the top wall direction. The first plate section 11 and the side wall form a first water inlet channel that guides water entering from the bottom water inlet to the top, and the second plate section 12 and the top wall and side wall form a second water inlet channel that guides water horizontally to the open upper end of the first chamber.

[0057] The first partition plate 10 described in this embodiment includes a third plate segment 9 extending along the side wall direction and a fourth plate segment 8 extending along the top wall direction. The third plate segment 9 divides the hollow chamber into two first chambers 14 and second chambers 15 with closed bottoms and open tops. The fourth plate segment 8 extends toward the upper opening of the first chamber 14. The end of the fourth plate segment 8 exceeds the end of the second plate segment 12. A vertical water retaining plate 7 is provided at the connection between the third plate segment 9 and the fourth plate segment 8.

[0058] The end of the fourth plate segment 8 of this embodiment exceeds the end of the second plate segment 12. In this way, when water is stored in the first chamber 14 and cold water needs to be introduced into the inner tank through the second chamber 15, the water entering through the water inlet 2 is guided to the upper opening of the first chamber 14 through the water inlet channel, and is blocked by the longer extended fourth plate segment 8 and guided into the second chamber 15, thereby preventing the entering cold water from directly entering the first chamber 14 and performing heat exchange with the stored water heated by the recovered heat, causing the stored water temperature to drop, thereby affecting the efficiency of heat recovery.

[0059] At the same time, a vertical water baffle 7 is provided at the connection between the third plate segment 9 and the fourth plate segment 8 . When water needs to flow into the first chamber 14 , the vertical water baffle 7 blocks the water from directly entering the second chamber 15 .

[0060] Furthermore, preferably, the fourth plate segment 8 is arranged to be inclined downward from one end connected to the third plate segment 9 to one end extending into the upper opening of the first chamber, so as to better guide the incoming water into the interior of the first chamber 14 .

[0061] In order to maintain the air pressure inside the dishwasher water storage device balanced with the external environment, the shell 1 described in this embodiment is provided with an air pressure balance port 6 connecting the first chamber 14, the second chamber 15 and the external environment. The position of the air pressure balance port 6 is higher than the highest water level of the second chamber 15.

[0062] Preferably, the air pressure balance port 6 of this embodiment is arranged inside the second chamber 15 .

[0063] Furthermore, the outer wall of the housing 1 has a recessed structure 5 at the position corresponding to the air pressure balance port. One end of the recessed structure 5 is flush with the outer wall of the housing to ensure that the dishwasher water storage device can be fully connected to the outside even if it is installed close to the dishwasher.

[0064] This embodiment also provides a dishwasher having the dishwasher water storage device, comprising a water inlet pipe and an inner tank having a washing chamber therein. The water inlet of the dishwasher water storage device is connected to the water inlet pipe, and the first water outlet and the second water outlet of the dishwasher water storage device are respectively connected to the washing chamber of the inner tank. The water inlet is provided with a water inlet control valve for controlling its on-off, and the first water outlet is provided with a first water outlet control valve for controlling its on-off.

[0065] It should be noted that the water inlet pipe of this embodiment needs to control whether the water inlet pipe is connected to the household tap water pipe. A second water outlet control valve can also be set on the second water outlet of this embodiment to control its on and off.

[0066] The dishwasher of this embodiment can store water in the first chamber by adopting a dishwasher water storage device, and absorb the heat emitted by the inner tank during the heating and washing process to be heated, and then used to heat water for subsequent washing processes, thereby realizing heat recovery and utilization, reducing the energy consumption of the dishwasher, reducing the power consumption of the dishwasher, and reducing the user's usage costs.

[0067] The dishwasher of this embodiment adopts a dishwasher water storage device to directly fill water into the inner tank, store heat recovery water, and control the heat recovery water to be discharged into the inner tank or continue to discharge cold water into the inner tank according to the needs of the washing process. The dishwasher water storage device is combined with a one-inlet and two-outlet water channel, which greatly simplifies the connection of the water channel. At the same time, only a control valve needs to be set on the first water outlet, and a control valve is not required on the water inlet, which reduces the use of control valves, simplifies assembly, and reduces the manufacturing cost of the dishwasher.

[0068] The embodiment also provides a control method of the dishwasher, the dishwasher controls the first water outlet control valve to be opened, and water in the water inlet pipeline directly enters the inner container after passing through the water storage device for the dishwasher.
