Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with accompanying drawing and embodiment, also described the technical problem and beneficial effect that the technical solution of the present invention solves simultaneously, it should be pointed out that described embodiment is only intended to facilitate the understanding of the present invention, and It has no limiting effect on it.

[0038] Such as figure 1 As shown, the piston type water tank proposed by the present invention is composed of a water tank, a piston 2, a valve connecting rod 3, 2 automatic reversing valves 4, 2 energy storage springs 5, 2 energy storage spring supports 6 and 2 special water inlet and drainage The two automatic reversing valves 4 are symmetrically installed in the center of both sides of the water tank. The two are connected by the valve connecting rod 3 in the water tank. The piston 2 is set on the valve connecting rod 3 and can be moved along the valve connectin...

Abstract

The invention relates to a piston type water tank and belongs to the technical field of household appliances. The water tank is partitioned into two isolated spaces through a piston, heated hot water is isolated with and not mixed with newly fed cold water, and relative stability of water temperature is guaranteed. When the piston type water tank is used, a water inlet valve on one side (end A) of the heated hot water is closed, and a water outlet valve is opened; a water inlet valve of the other side (end B) of the heated hot water is opened, the water outlet valve is closed, the B-end inlet water pressure pushes the piston to move towards the A-end hot water (water outlet) side, and the hot water is pressed out. After the hot water is emptied, the A-end water inlet valve is opened, the water outlet valve is closed, cold water enters the tank, the hot water is pushed by the piston to be discharged out of the water outlet valve, the operation is conducted repeatedly, and constant water temperature is achieved. Compared with the prior art, no external power is needed, energy is saved, the size is small, and the cost is lower due to the pure mechanical structure.

Description

technical field [0001] The invention relates to a water tank, in particular to a piston type water tank, which belongs to the technical field of household appliances. Background technique [0002] At present, the domestic water heaters on sale in the household appliance market often experience the phenomenon of "heating first and then cooling down" during use. The reason for this phenomenon is that the water temperature in the water tank drops due to the cold water entering the water tank during the use of the heated hot water. [0003] Although some water heaters also claim to be able to maintain a constant temperature, the method to solve the problem: one is to adjust the heating time by the temperature control switch, if the water consumption is large and the water intensity is high, the stability of the water temperature cannot be guaranteed; the other is to use Double water tank system, that is to say, the two water tanks are connected by pipelines, and they are heated...
