Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation that is used to not have the Teat pump boiler of the present invention under the special hot water return pipe situation; And
Fig. 2 is the structural representation that is used to have the Teat pump boiler of the present invention under the special hot water return pipe situation.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the present invention.
According to embodiments of the invention, a kind of Teat pump boiler is provided, as shown in Figure 1, comprising: water tank 10; Cold water inlet 30; This cold water inlet 30 has the cold water water inlet end that is connected with outside water inlet pipe; This cold water water inlet end is provided with check valve 31, and the other end of cold water inlet 30 is the cold water water side of stretching into water tank 10 inside, and the shunting end that is arranged on check valve 31 downstream parts; Water pump 50; Has the pump water inlet 51 that is connected with the shunting end of cold water inlet 30; This pump water inlet 51 is provided with first magnetic valve 53; Between the cold water water inlet end of cold water inlet 30 and pump water inlet 51, be connected with first return pipe 70, this first return pipe 70 is provided with second magnetic valve 71.
Teat pump boiler according to the embodiment of the invention; Through being connected first return pipe 70 between the cold water water inlet end of cold water inlet 30 and the pump water inlet 51; And second magnetic valve 71 is set on first return pipe 70, make the user can stop using hot water after a period of time can through water pump 50 with pipeline in the water that reduced of temperature draw back condenser and heat once more, guaranteed that the user can use hot water at any time; Eliminate the stand-by period of discharging cold water, practiced thrift water resource simultaneously.
The Teat pump boiler of the embodiment of the invention shown in Figure 1 can be used for the user is not provided with special hot water return pipe when finishing situation; When the user stops using hot water after a period of time; The temperature of original hot water can reduce, and all wants when the user opens hot water tap or shower nozzle once more earlier cold water to be bled off, and the user has to wait for a period of time; The cold water of emitting is also wasted; And the Teat pump boiler of the embodiment of the invention can be drawn back the cold water of low temperature through starting water pump 50, and on the one hand, cold water flows into water pump 50 and is delivered to heat pump portion 80 through pumping line 55 through first return pipe 70; On the other hand, heat pump portion 80 is responsible for providing thermal source that cold water is heated.Particularly; Evaporimeter 81 flows to compressor 83 with inhaled air,, and the HTHP air is delivered in the condenser 85 air boil down to HTHP air by compressor 83; Refrigerant in the condenser 85 absorbs the airborne heat temperature of HTHP and raises; Cold water to water pump 50 pumpbacks heats, and heated hot water is entered in the water tank 10 by the condenser outlet pipe 851 of condenser 85, uses in order to the user; And discharge by condenser 85 after the heat release of HTHP air, get back in the evaporimeter 81 through cut-off equipment 87.
As can be seen from Figure 1; Contact place at first return pipe 70 and pump water inlet 51 is provided with inflow temperature sensor 90; Condenser outlet pipe 851 is provided with leaving water temperature sensor 853; These two temperature sensors all are connected with water heater controller 40 signals, make water heater controller 40 can detect the temperature of the water inlet of 50 suction of water pump in real time, and pass through the leaving water temperature that discharge condenser 85 heating backs.
It can also be seen that from Fig. 1 pump water inlet 51 is provided with first magnetic valve 53, this first magnetic valve 53 is arranged on the upstream end of the contact of first return pipe 70 and pump water inlet 51, and this first magnetic valve 53 is preferably open type; First return pipe 70 is provided with second magnetic valve 71, and this second magnetic valve 71 is preferably closed type.In the process of above-mentioned cold water pumpback, first magnetic valve 53 cuts out, with prevent water pump 50 when drawing water with the water suction in the water tank 10, and second magnetic valve 71 is opened, and flows into water pump 50 swimmingly with the cold water that guarantees pumpback.
Along with the development of present finishing level, the user tends to reserve special hot water return pipe when finishing, and Teat pump boiler shown in Figure 2 is exactly the Teat pump boiler that the embodiment of the invention is applicable to the situation with special hot water return pipe.
As can be seen from Figure 2; The Teat pump boiler that the embodiment of the invention is used to have the situation of special hot water return pipe also comprises second return pipe 20; It is provided with second check valve 21; One end of this second return pipe 20 is connected with outside hot water return pipe, and the other end is connected to the contact place of the cold water inlet 30 and first return pipe 70.In this case; When startup water pump 50 carried out the cold water pumpback, first magnetic valve 53 cut out, and second magnetic valve 71 is opened; Cold water flows into water pump 50 from the hot water return pipe of outside through second return pipe 20, delivers to heat pump portion 80 by pumping line 55 again and heats once more.
See figures.1.and.2; The Teat pump boiler of the embodiment of the invention also has outer cover of water heater 60; In order to save the Teat pump boiler occupation space; Can water tank 10, cold water inlet 30, water pump 50, first return pipe 70, inflow temperature sensor 90, second return pipe 20, water heater controller 40 and whole heat pump portion 80 all be arranged on outer cover of water heater 60 inside, also can whole heat pump portion 80 be arranged on outer cover of water heater 60 outsides separately.
From above description, can find out that the above embodiments of the present invention have realized following technique effect:
In an embodiment of the present invention; Through being connected first return pipe 70 between the cold water water inlet end of cold water inlet 30 and the pump water inlet 51; And second magnetic valve 71 is set on first return pipe 70, make the user can stop using hot water after a period of time can through water pump 50 with pipeline in the water that reduced of temperature draw back condenser and heat once more, guaranteed that the user can use hot water at any time; Eliminate the stand-by period of discharging cold water, practiced thrift water resource simultaneously.
And, in an embodiment of the present invention,, can make Teat pump boiler be applicable to situation with special hot water return pipe through second return pipe 20 is set, increased the use flexibility of Teat pump boiler.
