Description of drawings

Fig. 1 is the longitudinal profile schematic diagram of thermal balance type water heater of the present utility model.

The specific embodiment

As shown in Figure 1, thermal balance type water heater of the present utility model comprises: water tank 3, heater 4, heat collector 10, compressor 12, expansion valve 15, cabinet 14 and fan 8, water tank 3 is in the upper end of cabinet 14, water tank 3 and cabinet 14 are an integral body, separate with dividing plate 5 between the two, heat-insulation layer 2 is equipped with in the outside of water tank 3.Heater 4 is housed in the water tank 3, and outlet valve 1 is equipped with on the top of water tank 3, and water intaking valve 6 is equipped with in the bottom.Have air outlet 7 on the sidewall of cabinet 14, have air inlet 13 on the diapire 11 of cabinet 14, supporting leg 9 also is equipped with in the bottom of cabinet 14, makes diapire 11 built on stilts of cabinet 14.So that air enters in the cabinet 14 from indoor.Air outlet 7 evenly distributes on the sidewall of cabinet 14, and air inlet 13 evenly distributes on diapire 11.Fan 8, heat collector 10, compressor 12 and expansion valve 15 are housed in the cabinet 14, fan 8 is contained in the anterior of heat collector 10 and faces air outlet 7, one end of heat collector 10 links to each other with the liquid outlet of the heater 4 of water tank 3 by expansion valve 15, the other end of heat collector 10 links to each other with the inlet of the heater 4 of water tank 3 by compressor 12, heat collector 10, compressor 12 heaters 4 and expansion valve 15 are formed a closed circuit, and cold-producing medium is flowing in this loop.
