Example Embodiment

[0026] The present invention heats the water in the clean water tank through the coolant in the engine's return water pipeline flowing through the clean water tank system. The present invention will be further described below with reference to the accompanying drawings:

[0027] Such as figure 1 The shown water purification tank system for passenger car toilets in cold areas includes a water purification tank 1, a water filling pipe 5, a water outlet pipe 10, a heating pipe, a normally open solenoid valve 2, a normally closed solenoid valve 3, and a first three-way 13 and the second tee 9. The water filling pipe 5 is located at the top of the water purification tank, which can effectively prevent the water in the water purification tank 1 from flowing back to the water filling pipe 5, thereby avoiding the inability to add water due to the freezing of water in the water filling pipe 5. The water outlet pipe 10 is located at the bottom of the clean water tank, and is connected to t...

Abstract

The invention relates to a clean water tank system for a coach toilet in a cold area and a control method of the clean water tank system. The clean water tank system comprises a clean water tank, a water adding pipe, a water outlet pipe, a heating pipe, a normally open solenoid valve and a normally closed solenoid valve, wherein the water adding pipe is positioned on the top of the clean water tank; the water outlet pipe is positioned at the bottom of the clean water tank and is connected with a water inlet of a water pump of the coach toilet through a pipeline; the heating pipe is arranged in the clean water tank; the water inlet of the heating pipe is connected with a water outlet of an engine water return pipeline through a first tee joint, and the water outlet of the heating pipe is connected with a water inlet of the engine water return pipeline through the normally open solenoid valve and a second tee joint; the normally closed solenoid valve is arranged between the first tee joint and the second tee joint. According to the technical scheme, the clean water tank system can effectively solve the problem of difficulty in water usage in the coach toilet in the cold area, meets the requirements of users and ensures that the coach toilet under the low temperature environment is more humanized.

Description

technical field [0001] The invention relates to the technical field of passenger cars, in particular to a clean water tank system and control method for passenger car toilets used in cold regions. [0002] Background technique [0003] In my country, there is currently no toilet system that is really suitable for winter use in cold areas, especially the toilet clean water tank system. The conditions in cold regions are extremely harsh, and dripping water turns into ice, which is very prone to problems with water use in passenger car toilets. If the passenger car is in a cold environment with continuous low temperature, the water in the clean water tank and the water pipe of the passenger car will freeze, which will affect the normal use of the passenger car toilet. Even if the water in the passenger car clean water tank and the water pipe in the cold area does not freeze, the water used by passengers to wash their hands will be ice-piercingly iced, which will cause damage ...
