This combustion gas pump 10 is known technology just, therefore omits the description to its detail operations.
Yet traditional heat pump 10 of structure needs independent connection flexible pipe 26 as mentioned above, the combustion gas of leaking from gas valve 20 in order to suction, and described combustion gas sent in the air intake filter 14, therefore be difficult to save buying and the cost that is connected flexible pipe 26 is installed.In addition, damage if connect flexible pipe 26, even also can there be the danger of gas explosion owing to gas leakage in small damage.
And, be used in gas valve 20 in the heat pump 10 in operating process usually by coil heats.At this moment, if gas valve 20 ambient air temperature height, because there is not cooling unit, the heat that gas valve 20 self produces will make gas valve 20 be further heated, and this may cause catching fire.
Summary of the invention
Therefore, the present invention is intended to solve the problems referred to above that take place in the prior art.The purpose of this invention is to provide a kind of gas-engine-driven heat pump, even in gas valve, take place under the situation of gas leakage, this heat pump is drawn into via air intake filter and guarantees in the gas engine gas explosion can not take place or catch fire by all being leaked combustion gas, and by outside air continued when the operation to import to gas valve around prevent that the temperature of gas valve from sharply raising.
In order to realize the above and other purpose, according to technological scheme of the present invention, provide a kind of gas-engine-driven heat pump, this heat pump comprises: gas engine 12; Engine agitator 16, it will wait that combustion gas and the outside air of supplying with gas engine 12 mix mutually; Air intake filter 14, it is connected with impurity screening with engine agitator 16; And combustion gas clack box 30, wherein having gas valve 20, this combustion gas clack box is connected with air intake filter 14, and can aspirate outside air.Wherein, operate this combustion gas clack box 30, even so that combustion gas is leaked from gas valve 20, all leakage combustion gas also can be sucked in the gas engine 12, and outside air can be imported to constantly gas valve 20 around.
Combustion gas clack box 30 can also comprise aspirator 32, this aspirator be positioned at the outside air that is sucked on the surface of process.
This engine agitator is positioned at combustion gas clack box outside, and this heat pump can also comprise supply hose 24, and this supply hose is connected between the outside and gas valve of engine agitator 16.
This heat pump can also comprise supply hose 25, and this supply hose is connected on the gas valve 20 in the combustion gas clack box 30, to supply with combustion gas to engine agitator 16.
Description of drawings
From the detailed description below in conjunction with accompanying drawing, above-mentioned his purpose, the feature and advantage with it of the present invention will be more distinct.In the accompanying drawings:
Fig. 1 is the view that traditional gas-engine-driven heat pump is shown;
Fig. 2 illustrates the view of gas-engine-driven heat pump according to an embodiment of the invention; And
Fig. 3 illustrates the view of gas-engine-driven heat pump according to another embodiment of the present invention.
Embodiment
Describe exemplary embodiments of the present invention in detail hereinafter with reference to accompanying drawing.
Fig. 2 illustrates the view of gas-engine-driven heat pump according to an embodiment of the invention, wherein, identical reference character be added in Fig. 1 on the components identical, Therefore, omited repeat specification wherein.
With reference to figure 2, gas-engine-driven heat pump 10 comprises: gas engine 12, and it is by gas driven; Air intake filter 14, its end that is connected to gas engine 12 is blended in the impurity in the outside air of supplying with gas engine 12 with filtration; And engine agitator 16, it is arranged between gas engine 12 and the air intake filter 14.
