Description

Technical Field

[0001] This utility model relates to the field of water heaters, and in particular to a compact water heater with a water storage compartment. Background Technology

[0002] Chinese patent application CN109297180A discloses an intelligent preheating circulating gas water heater, a preheating circulating system, and a control method. The system comprises an inlet pipe, a water pump, a heat exchanger, an outlet pipe, a three-way valve, a bypass pipe, and a storage tank, forming an internal circulation system. When the water outlet temperature T2 in the storage tank is less than a preset circulation temperature Tx, the water pump circulates the water within the internal circulation system, and the gas water heater further heats the water within the internal circulation system. The hot water temperature is heated to a level not less than the circulating temperature Tx. "The end of the hot water outlet pipe is connected to a return water pipe, which is connected to the cold water inlet pipe. A second one-way valve is installed on the return water pipe, leading to the cold water inlet pipe. The cold water inlet pipe, storage tank, inlet pipe, outlet pipe, three-way valve, hot water outlet pipe, and return water pipe constitute an external circulation pipeline system." Because of the internal and external circulation systems, users can enjoy instant hot water without uneven water temperature.

[0003] The problem with existing technology is that installing water pumps and storage tanks in water heaters increases their size. Therefore, dual-circulation water heaters are relatively large, especially when viewed from the front, as they occupy a large area of ​​wall space after installation. Utility Model Content

[0006] As a further improvement to the above technical solution, the long axis of both the inlet solenoid valve and the water flow switch solenoid valve is arranged in the front-to-back direction.

[0007] As a further improvement to the above technical solution, the water inlet solenoid valve, water pump, water flow switch solenoid valve and water storage container are arranged in sequence from bottom to top, and the heat exchanger is located on the left or right side of the water storage container.

[0008] As a further improvement to the above technical solution, the inlet tee and the inlet solenoid valve are arranged in the left-right direction, and the front end of the water pump is connected to the top of the inlet tee.

[0009] As a further improvement to the above technical solution, the top and bottom of the water storage container are both welded with fixing plates, the rear end of the fixing plate is provided with a bending part, the bending part is provided with a connecting hole, the connecting hole is used to connect the back plate of the water heater; the rear end of the water pump is also provided with a fixing plate.

[0010] As a further improvement to the above technical solution, a temperature sensor is installed on the water outlet tee.

[0011] The beneficial effects of this utility model are: because the long shaft of the water pump is arranged along the front-to-back direction, the water heater of this application has a smaller left-to-right dimension, a more compact structure, and a smaller water heater area when viewed from the front.
