Pump is installed in end cap, and the water inlet adapter of water pump is connected with running water pipe, the ladle body bottom Jiang Shui that water outlet pipe is covered from end cap
Import in ladle body, the side of end cap is provided with service ports, the lateral wall insulation layer covering of end cap.
In a kind of embodiment of above-mentioned technical proposal, the end cap is connected with the bottom of the ladle body using manner
It is integrated, in the upper end port of the bottom insertion end cap of ladle body.
In a kind of embodiment of above-mentioned technical proposal, the insulating layer uses the foaming layer of at least 50mm thickness.
In a kind of embodiment of above-mentioned technical proposal, the outer side bottom surface of the end cap is provided with support rim.
In a kind of embodiment of above-mentioned technical proposal, the hot water exit of the water tank is connected with pressure sensor, pressure
The data of collection are transmitted to host by force snesor.
In a kind of embodiment of above-mentioned technical proposal, the side wall of the ladle body is connected with water tank temperature sensor and refrigerant
The data of collection are transmitted to host by connecting tube, water tank temperature sensor, and refrigerant is by coolant connecting tube between host and ladle body
Circulation.
In a kind of embodiment of above-mentioned technical proposal, temperature sensor, temperature sensor are connected with the return pipe
The data of collection are transmitted to host.
In a kind of embodiment of above-mentioned technical proposal, the connecting pin of the running water pipe and the booster pump is sequentially connected
There are gate valve and one-way relief valves, the end of return pipe is connected on the running water pipe between gate valve and one-way relief valves, unidirectional peace
Full valve is located at outside the end cap, and the outlet of one-way relief valves is connected with the water inlet adapter of water pump in end cap.
Water pump is integrated in the end cap of water tank bottom by the utility model, and the water outlet of water pump and the water inlet of water tank connect
Also it is hidden in end cap.Water tank routinely is only needed to take over operation during installation, it is not only beautiful, also eliminate the prior art and exist
The operation of booster pump is installed on the outlet pipe of water tank.The running water pipe of return pipe access at the same time, makes water pump also be returned with the prior art
The function of water pump, eliminating the prior art needs the operation of separately installed back water pump.That is the utility model one is integrated in
The water pump of water tank bottom has had the function of the booster pump and back water pump on prior art peripheral hardware pipeline concurrently, simplifies configuration, improves
Comfort, simplifies field-mounted process, only needs connecting line.The existing heat insulation effect of insulating layer of end cap outer wall, again
Play the role of sunshade, can not only prevent it is freezing, but also be avoided that be exposed to the sun caused by high temperature damage, extend the service life of water pump.Do not having
When having bathing, water pump is used as back water pump, the water temperature in pipeline is kept setting value, ensures the using effect of instant-heating；When washing
When bath pressure is inadequate, water pump is used as booster pump, increases hot water effluent's pressure, makes user's body-sensing more comfortable.In addition, this practicality is new
The low installation site of type water pump is also avoided that because the gas in pipeline causes the idle running of water pump.
