Gas water heater with bathroom heating and control method of gas water heater

Abstract

The invention discloses a gas water heater with bathroom heating. The gas water heater comprises a gas water heater body, a main controller arranged on the gas water heater body, a cold water inlet pipe, a hot water outlet pipe, a water use site arranged on the hot water outlet pipe, a water outlet temperature sensor and cold water branch pipes connected between the water use site and the cold water inlet pipe, wherein the cold water inlet pipe and the hot water outlet pipe are connected with the gas water heater body; the hot water outlet pipe and the cold water inlet pipe are connected through a pipeline or one-way valve to form a circulation loop, and a circulation pump is arranged on the circulation loop; the circulation pump and the water outlet temperature sensor are connected with the main controller; a heat sink arranged in a bathroom is in parallel connection to the hot water outlet pipe, the water inlet end and the water outlet end of the heat sink are communicated with the hot water outlet pipe through a reversing valve and a check valve, and an environment temperature sensor connected with the main controller is further arranged in the bathroom. A special heating water returning pipe does not need to be arranged, an electric switching valve is not needed, the structure is simple, mounting and use are convenient, and the invention further provides a control method of the gas water heater.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a gas water heater with bathroom heating and a control method thereof. Background technique [0002] At present, the bathroom heating mainly has the following methods: 1) floor heating, 2) radiator heating, and 3) electric heater heating. However, the winter time in southern my country is short, the temperature is low but not cold, and the central heating conditions cannot be met. Houses are generally not laid heating pipelines during decoration, so the floor heating method is not suitable. Although the radiator can be arranged after the decoration is completed, the heating pipeline leaks on the wall, which affects the appearance of the decoration. The radiator consumes a lot of materials, and the heating time in the south is short. A comprehensive comparison of this heating method is not ideal. Electric heater heating is currently the most used method in southern fa...

Problems solved by technology

Air heaters and oil heaters heat up slowly, resulting in long waiting times and poor heating experience

[0003] In the prior art, it is also proposed to use a gas water heater to heat the bathroom. However, due to the large difference between the heating water temperature and the bathing water temperature, it is usually necessary to lay two return water pipes for heating and bathing. There is a defect that the water temperature fluctuates greatly, and the use effect is not ideal
