Description

Technical Field

[0001] The utility model relates to the technical field of hot water supply for dishwashers, in particular to a hot water supply device for dishwashers that utilizes the waste heat of a stove. Background Technique

[0002] A hot water supply device for a dishwasher that utilizes the waste heat of a stove mainly supplies hot water to the dishwasher by using the hot water generated from the recovery of the waste heat of the stove, which can not only help save energy but also reduce the consumption of conventional energy.

[0003] For this reason, a hot water supply device for a dishwasher that utilizes the waste heat of a stove disclosed in Chinese Patent Publication No. "CN110419995A" has a storage hot water tank connected to the rinsing tank of the cleaning tank through a pipeline, and a spray head is provided at the top of the rinsing tank. A hot water supply pump is installed in the pipeline. The hot water in the storage hot water tank comes from a hot water device for recovering the waste heat of stove flue gas. The hot water device for recovering the waste heat of stove flue gas has a surplus hot water tank. The storage hot water tank is connected to the surplus hot water tank. A cold water inlet pipeline is connected to the storage hot water tank, and an external tap water source is connected. A hot water bag is installed in the dishwasher for storing hot water, which is installed in the pipeline between the storage hot water tank and the rinsing tank of the cleaning tank. After the stove flue gas is concentrated through a flue gas pipe, the flue gas pipe is installed in the surplus hot water tank for heat exchange to heat the hot water in the surplus hot water tank. In this process, the water in the surplus hot water tank directly enters the storage hot water tank and is used for dishwashing. The stove flue gas may not be able to fully heat the cold water at one time, resulting in the water temperature not reaching the temperature of the dishwashing water, making the subsequent dishwashing not clean. And the water in the storage hot water tank may become a large amount of cold water if there is no timely hot water supply. At this time, when hot water enters again, the water temperature cannot be quickly and evenly distributed, thus affecting dishwashing. Therefore, this application proposes a more efficient hot water supply device for dishwashers that utilizes the waste heat of a stove. Summary of the Utility Model

When the striking block 16 rotates to not contact the block to be struck 13, the water pressure flowing into the piston cylinder 6 through the second water pipe 14 is used to make the piston 15 return to its original position. Repeating this operation can make the water in each pipe in the pipe box 1 and the water storage tank 3 continuously circulate to absorb the heat emitted by the cooking range, thereby uniformly heating the cold water. After reaching the temperature of the water for dishwashing, the water valve controlling the dishwashing water pipe 5 is opened, and the qualified hot water flows into the dishwashing device, saving energy and enabling better dishwashing at the same time.
