Abstract

The invention relates to an improved heat pump water heater. The improved heat pump water heater adopts a dual-gate hydrant to ensure that water tanks do not bear pressure, so the two water tanks of big and small can be made of ceramics or plastics and arranged below a wash trough of a toilet, thereby utilizing waste space, ensuring no cold water stored in pipe and realizing immediately heating after opening. The amount of the prepared hot water can be changed due to reasons of seasonal changes and etc., to achieve energy conservation and the improved heat pump water heater can also be respectively matched with heat pumps of air sources and wastewater sources, thereby facilitating the adoption of the different heating modes in the regions with the different temperatures. The improved heat pump water heater can obtain adequate living hot water for troops, factories and enterprises, school dormitories, hotels and families, thereby providing energy-saving water heating devices.

Description

Adopt the Teat pump boiler of double-gate tap, two water tanks

Affiliated field: Teat pump boiler

Technical background: electric heater will be accomplished plug and play, and two approach are arranged, the one, and with the directly-heating type water heater of big electric current, advantage is without water tank, shortcoming is that the too big waste of electric current is not little.The 2nd, leave in the water tank standby after electricity consumption is directly heated.This method can be used with daytime after the paddy electrical heating at night, but two ways all are to exchange heat energy for the high-grade energy, can't compare with the heat-pump-type heating.Pump formula water heater is that the heat in air and the waste water " pump " is advanced boiler, but pump advanced 2-5 used heat doubly when a electricity generated heat, efficient is best undoubtedly, but the intrinsic shortcoming of water tank (commercially available heat pump water box is huge and take up an area of, and the standby water yield is uncontrollable etc.) is failed solution.

1, owing to will lean on the pressure of running water to promote water outlet, water tank is pressure-bearing all the time, has to metal material and does the circular hydraulic pressure that tackles.But metal easily loses, and the constantly soaring trend of the shortcoming of leakiness, price just can't overcome

2, bearing type water tank will keep a full case all the time, and it is unnecessary to seem during winter, can not lack " burning " again, on the market about 20 liters the little water heater out of stock fact expressed the consumer and wished the hope that has the adjustable water heater of capacity to occur, be badly in need of design and change to some extent.

Summary of the invention:

1, improving at present, commercially available valve (being commonly called as tap) makes water intaking valve switch and outlet valve interlock (being the double-gate tap), (Fig. 2) allow the user when opening discharging valve, in fact also opened water intaking valve (12.3 among Fig. 1) simultaneously when closing this discharging valve, in fact also the connection band has been closed water intaking valve.Like this, be installed in the closing of water intaking valve servo-actuated discharging valve before the water tank and close, just blocked the transmission of hydraulic pressure, make water tank no longer be in artesian condition.Open simultaneously with outlet valve because of inlet valve again, hydraulic pressure is released by water outlet and is significantly reduced, and the material of water tank just can no longer be limited to metal like this, pottery is all alternative with plastics, and shape also no longer is limited to circle, and the space can make full use of, but two water tank squarelys are installed in below the kitchen sink.

2, two water tanks make small one and large one and can constitute three kinds of outputs and change to answer adaption demand, and accomplish the heating of an another when using.Method is the pipe-line that triple valve and check valve are formed, and triple valve is connected left and right or when connecting entirely, is respectively the left and right and full heating of heating.Satisfy the output of Various Seasonal with this, as being summer all-pass, then use a wherein case winter, check valve has guaranteed not allow the direct inlet water tank of cold water.

Description of drawings:

It in Fig. 1 frame of broken lines four big parts of heat pump: compressor (5), capillary (4), double-tube heat exchanger (3) as the condenser heat release, waste water tank (6) as the evaporimeter heat absorption, perhaps with the air heat exchanger heat absorption (7) that fin is arranged, water inlet pipe is (1) among Fig. 1, water pump is (2), water tank is respectively that 8.1 and 8.2 corresponding taps are 12.1 and 12.2, triple valve is (11), check valve is 10.1 and 10.2, temperature probe is respectively 9.1 and 9.2, the exhaust insurance is 13.1 and 13.2, Fig. 2 adds a valve 12.3 on a common condensed water tap, this tap upwards is that state A connects 12.3, close to next, be to the right state B, 12.2 connect, then connect 12.1 left

The specific embodiment:

The present invention is actually the modified water tank of Teat pump boiler, guarantee the feasible of non-press-bearing water tank by a special tap, control by triple valve and to be heated water tank, thereby accomplish that output can select, such as 8.1 water tanks is 30 liters, 8.2 water tank is 70 liters, then can be by the determining positions heating load of triple valve: state is 30 liters to turn over 90 degree clockwise is 100 liters among Fig. 1, and turning 90 degrees then is 70 liters again.

Claims

1, a kind of Teat pump boiler, it is characterized in that adopting double-gate tap and unpressurized pair of cisten mechanism, the pipeline of being made up of triple valve and check valve is big by connecting, connection is little, connect the heat supply water mode that three State Selection can obtain middle or small, greatly little three kinds of different amounts entirely.Two water tanks can be made by pottery and plastics, are installed under the kitchen sink side by side.

2, the used double-gate tap of the described Teat pump boiler of claim 1 is characterized in that Duoing a valve than general tap, allows this tap in the break-make discharging valve, and also the water intaking valve before the break-make water tank guarantees two valves break-make simultaneously, makes no longer pressure-bearing of water tank.
