Description

An electric heating dual-purpose wall-hung boiler for heating and bathing

technical field

The invention relates to an electric wall-hung furnace, in particular to an electric wall-hung furnace heated by a nano-semiconductor electric heating tube.

Background technique

Existing equipment for family heating is mainly a gas wall-mounted heating furnace, which is divided into two kinds of gas boilers, natural gas and coal gas. The biggest disadvantage of the gas wall-hung boiler is that it is easy to leak gas and cause gas poisoning, especially in winter, in order to keep warm and save energy, the doors and windows are sealed, and the ventilation is not smooth, which is more prone to safety hazards; and the electric heat conversion rate of the gas wall-hung boiler is relatively low, resulting in waste of energy. During operation, a large amount of smoke will be generated, polluting the environment. Electric wall-hung boilers are just quite popular among the masses like this, but most existing electric wall-hung boilers have a single function and cannot satisfy people's needs for heating and daily life water at the same time.

Contents of the invention

The object of the present invention is to provide a dual-purpose wall-hung boiler for heating and bathing that is heated by a nano-semiconductor electric heating tube.

In order to achieve the above object, the technical scheme adopted in the present invention is as follows:

An electric wall-hung boiler for heating and bathing, characterized in that: the electric wall-hung boiler includes a heating mechanism and a domestic hot water mechanism, wherein the heating mechanism mainly includes a nano-semiconductor electric heating tube, a circulating water pump, a heating temperature probe, a heating safety valve, The water inlet control solenoid valve, the water outlet control solenoid valve, the three-way steering valve and the central controller are all coordinated and controlled by the central controller; the domestic hot water mechanism of the present invention mainly includes a water flow sensor, a plate heat exchanger, The hot water temperature probe, water filling valve, sealed expansion tank and central controller, etc., are all coordinated and controlled through the central controller.

In the electric-heating dual-purpose wall-hung boiler for heating and bathing, the hot water heating device is a nano-semiconductor electric heating tube.

In the electric heating dual-purpose wall-hung boiler for heating and bathing, the water flow at the hot water heating device has two heating modes: series connection and parallel connection.

In the electric heating dual-purpose wall-hung boiler for heating and bathing, the heat exchange between heating water and bathing water is completed through a plate heat exchanger.

The water flow at the heating device of the present invention has two heating modes: series connection and parallel connection. Combining the domestic hot water mechanism and the heating mechanism can meet people’s dual needs for heating and bathing at the same time, and the heating hot water outlet pipe is separated from the bathing water outlet pipe. Set to ensure that the bathing water is clean and free from pollution from the long-term heating cycle scaling water.

detailed description

As shown in the figure, the electric wall-hung boiler of the present invention includes a heating mechanism and a domestic hot water mechanism. The heating mechanism mainly includes nano-semiconductor electric heating tube 11, circulating water pump 5, heating temperature probe 1, heating safety valve 2, water inlet control solenoid valve 13, water inlet control solenoid valve 2 15, water outlet electric valve 12, water outlet electric valve Two 16, three-way steering valve 10 and central controller etc., they all carry out unified coordinated control by central controller. The domestic hot water mechanism of the present invention mainly includes a water flow sensor 7, a plate heat exchanger 9, a hot water temperature probe 8, a water filling valve 4, a sealed expansion water tank 6, a bathing valve 20 and a central controller, etc. Carry out unified coordination and control.

When the user needs to heat, set the temperature in the central controller, select the heating mode (series or parallel), and press the button of the central controller to control the circulating water pump 5, and the cold water will flow in from the heating inlet pipe 3. When the heating mode When connected in series, the water inlet control solenoid valve 13 and the water inlet control solenoid valve 2 15 are closed, the upper ends of the water outlet electric valve 12 and the water outlet electric valve 2 16 are closed, and the lower ends are opened, and the water flows through three nanometer semiconductors in series. The electric heating tube 11 and the heating temperature probe 1 measure the temperature of the flowing water and send the signal to the central controller. When the temperature reaches the set temperature, the three-way steering valve 10 is controlled to make the water flow out through the heating outlet pipe 18. When the temperature does not reach the set temperature When the temperature is high, control the three-way steering valve 10 to make the water flow through the upper end of the plate heat exchanger 9, and then return to the nano-semiconductor electric heating tube 11 through the circulating water pump 5 to continue heating, and so forth until the temperature reaches the set temperature; when the heating mode is parallel , the water inlet control solenoid valve 13 and the water inlet control solenoid valve 2 15 are opened, the upper ends of the water outlet electric valve 12 and the water outlet electric valve 2 16 are both opened, and the lower ends are closed, and the water flows through three nanometer semiconductor electric heating tubes 11 in parallel. , and then the water flow direction is the same as that in series. When the user takes a bath, the temperature of the bath water is set in the central controller, and the bath clean water flows in from the bath inlet pipe 19, flows through the lower end of the plate heat exchanger 9, and the hot water temperature probe 8 measures the temperature of the water flow and transmits the signal For the central controller, when the temperature reaches the set temperature, the bath valve 20 is opened, and the water flows out through the bath outlet pipe 17 for domestic water; when the temperature does not reach the set temperature, the bath valve 20 is closed, and heating is continued until the temperature reaches set temperature.

The upper end and the lower end of the plate heat exchanger 9 are not connected, but heat can be exchanged. Therefore, the heating water and domestic water of this invention are separated from each other, and are not polluted by the long-term heating cycle scaling water.
