Hot water machine and its control method

Abstract

The invention discloses a water heater, wherein, the large water tank and the small water tank are connected through a connecting pipe, and a first electromagnetic valve is arranged on the connecting pipe; the first end of the first electric three-way valve is connected to the large water tank through the connecting pipe. The water inlet of the water tank is connected, the second end is connected with the water inlet of the small water tank through the connecting pipe, and the third end is respectively connected with the water outlet of the air energy heating device and the water outlet of the solar heating device through the connecting pipe; The first end communicates with the water return port of the large water tank through the connecting pipe, the second end communicates with the water return port of the small water tank through the connecting pipe, and the third end connects the water inlet of the air heating device and the water inlet of the solar heating device respectively through the connecting pipe connected. The invention ensures sufficient supply of hot water for users when they use temporary water, and also avoids waste caused by non-stop heating of water in a large water tank during off-peak periods.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water heater and a control method thereof. Background technique [0002] In order to meet the water demand of centralized water use units such as schools, hotels, factories, etc., water heaters are generally heated by a combination of air energy water heaters and solar water heaters, that is, combined water heaters. By combining the characteristics of air-energy water heaters and solar water heaters, the hot water needs of users can be met. [0003] Due to the lack of water resources and the large water consumption, the combined hot water machine will be equipped with a large water tank to fully supply users with water throughout the day. And to ensure that the large water tank of the combined water heater can meet the temperature required by the user, the user must heat the water in the large water tank to the required water temperature. However, when the water consumption is no...
