Example 1

The present embodiment provides a dishwasher, including: a housing 1; the cleaning cavity 2 is arranged inside the shell 1, and a spraying device 3 is arranged inside the cleaning cavity; the water collecting tank 4 is arranged below the cleaning cavity 2 and used for receiving the cleaning water sprayed out by the spraying equipment 3; the water inlet pipe 5 is connected to the water collecting tank 4; the water level acquisition device is arranged in the water collecting tank 4 or the shell 1; a first valve 6 and at least one second valve 7 provided on the inlet pipe 5, one of the first valve 6 and the second valve 7 being a normally open valve, the other of the first valve 6 and the second valve 7 being a shut-off valve.

In this embodiment, the cleaning liquid may be delivered into the water collecting tank 4 through the water inlet pipe 5, and the cleaning liquid may be a mixed liquid of water and a detergent such as a detergent, or may be pure water.

When water delivery is needed, the first valve 6 and the second valve 7 are controlled to be kept in an open state, once the first valve 6 is damaged, the second valve 7 can be controlled to be closed because the second valve 7 is a closable valve, and at the moment, even if the first valve 6 cannot be closed, water or cleaning liquid in the water inlet pipe 5 can be prevented from continuously flowing into the water collecting tank 4, so that water or cleaning liquid can be prevented from overflowing from the water collecting tank 4 or causing waste of water.

In the present embodiment, at least one of the first valve 6 and the second valve 7 is a solenoid valve. In this embodiment, the number of the second valves 7 may be one or more. When a plurality of second valves 7 are used, it is possible to effectively prevent the failure of the shut-off of the water feed pipe 5 when one of the second valves 7 is damaged.

In the dishwasher provided in the present embodiment, as shown in fig. 1, the water level obtaining device is a float 8, and the float 8 is disposed in the housing 1.

As shown in fig. 1, the buoy 8 is disposed at the bottom of the housing 1, and is electrically connected to the outside through a connector, and by disposing the buoy 8 in the housing 1, when the first valve 6 is damaged, water is continuously injected into the water collection tank 4, and after the water overflows from the water collection tank 4, the buoy 8 can monitor the water level, and when the water level rises to the position of the buoy 8, the buoy 8 can control the second valve 7 to turn off, thereby preventing the water from continuously flowing into the water collection tank 4 through the water inlet pipe 5.

Meanwhile, in order to further improve the monitoring precision of the water amount entering the water collecting tank 4, the present embodiment further includes a flow meter 9 disposed on the water inlet pipe 5, and the flow meter 9 is used for monitoring the water amount entering the water collecting tank 4. The flowmeter 9 is arranged, water flowing into the water collecting tank 4 can be counted, and under the condition that the water in the water collecting tank 4 does not flow out, the amount of water which can be contained in the water collecting tank 4 is constant, so that if the water flowing through the flowmeter 9 exceeds a preset amount and is still injected into the water collecting tank 4, the first valve 6 is damaged, and at the moment, the flowmeter 9 can control the second valve 7 to be closed, so that the water is prevented from being continuously injected into the water collecting tank 4.

In this embodiment, the water inlet pipe 5 is supported by a flexible pipe, the flow meter 9 is disposed on the flexible pipe, and meanwhile, the second valve 7 is controlled by the flow meter 9, and the flow meter 9 is provided with a controller, which is electrically connected with the second valve 7.

In the dishwasher of the present embodiment, as shown in fig. 1, in order to prevent the water in the water collecting tank 4 from flowing out from the four walls of the water collecting tank 4 due to the excessive amount of water after the first valve 6 is damaged, a water leakage hole 10 is formed at the upper edge of the water collecting tank 4. Specifically, the water leakage holes 10 themselves are provided at the top position of the water collecting sump 4, one in number. Meanwhile, as shown in fig. 1, the water leakage hole 10 is provided at a position above the float 8, so that the overflow of water can be detected at the first time.

The dishwasher provided by the embodiment further comprises an alarm device, and the alarm device is connected with the water level obtaining device.

Specifically, the alarm device may be a buzzer or a lighting device. As long as it can play a role of reminding the user.

The dishwasher provided by the embodiment is characterized in that a water return pipe 11 is arranged on the water collecting tank 4, the water return pipe 11 is connected with the spraying equipment 3, and a water pump is arranged on the water return pipe 11.

In this embodiment, as shown in fig. 1, a drain pipe 13 is provided on the water collection tank 4, and a water pump is provided on the drain pipe 13, so that water in the water collection tank 4 can be discharged to the outside by the water pump. When the dish washing work is advanced to a later stage, in order to improve the utilization efficiency of water, the drain pipe 13 may be closed at this time while the return pipe 11 is started. The water return pipe 11 pumps relatively clear water into the water collecting tank 4 again, so that water is recycled.

In the dishwasher provided by the embodiment, as shown in fig. 1, the spraying device 3 is a spraying arm, and the spraying arm is provided with a spraying hole.

In particular, a bowl basket is provided in the washing chamber 2, in which the dishes 12 are arranged, and the spray holes themselves are arranged below the bowl basket and spray the washing liquid in the direction of the bowl basket.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
