A desktop dishwasher dual water source control method and the desktop dishwasher

Abstract

The invention provides a double water source control method for a desktop dishwasher and a desktop dishwasher. The desktop dishwasher includes an inner container, a spray arm located in the inner container, a water tank connected to the inner container, and a drain pipe. The water tank is provided with a manual The water inlet, the automatic water inlet and the water outlet of the water tank, the automatic water inlet is connected to the tap water source through the first solenoid valve, the water filling pump is installed between the water outlet of the water tank and the inner tank, and the drain pump is arranged between the inner tank and the drain pipe, and the water tank It is equipped with a float valve to detect the full water level, and the dishwasher is also equipped with a circulating pump connecting the inner tank and the spray arm. The control methods include: water storage stage of the water tank, washing stage, and draining stage. The automatic water inlet is connected to the external water source through the first solenoid valve, so that the dishwasher water tank has the function of automatic water inlet, and the water enters the water tank first, and then the water in the water tank is pumped into the inner tank through the cooperation of the water filling pump and the circulation pump to realize the tableware. Washing, and finally realize the discharge of washing water, the control method of this desktop dishwasher is stable in water intake, and the detection of water source is accurate.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a desktop dishwasher. Background technique [0002] Existing dishwashers are of various types, and general dishwashers only have one of the two water inlet methods: automatic water inlet or manual water inlet. A dishwasher with a manual water inlet method has a manual water inlet on its top, and a high water level sensor detects the high water level in the water tank to determine whether there is water in the water tank. Dishwashers with an automatic water inlet method take water by directly connecting tap water to inject water into the inner tank, or by first feeding water into the water tank and then injecting water from the water tank into the inner tank. The automatic water inlet dishwasher adopting the latter method generally has an automatic water inlet at the bottom of the water tank, and water enters the water tank from the automatic water inlet. [0003] However, the ...

Problems solved by technology

[0003] However, the manual water-intake dishwasher needs to be manually filled with water, which is inconvenient to use; the automatic water-intake dishwasher that is directly connected to tap water to fill the inner tank takes a long time to fill the inner tank with water when the tap water flow is small during the washing process. , the washing efficiency of water inlet is low; manual water inlet and automatic water inlet cannot be selected according to needs, and user experience needs to be improved

[0004] In order to improve the product, there are product designs in the industry that combine manual and automatic water intake, but usually the water is manually added to the water tank, but the automatic water intake channel controls the on and off of the solenoid valve, and the water source directly enters the inner tank. The method can only rely on the time of water intake to control the on-off of the solenoid valve. In the case of unstable water pressure, the amount of water entering the inner tank through the automatic water supply channel is extremely unstable, and there is a large deviation in the water intake. At the same time, the automatic water supply channel cannot When the water source is cut off, when the automatic water supply is cut off, the water inlet process cannot be cut off in time through the opening and closing of the water inlet solenoid valve, and the water shortage can only be judged through the back-end washing stage, and the back-end judgment makes it impossible to distinguish It is not possible to give the user the most direct alarm prompt due to the water shortage caused by the water supply interruption, or the water shortage caused by the water leakage of the equipment
