Embodiment
As depicted in figs. 1 and 2, a kind of defrosting mechanism 100 is present embodiments provided, low-temperature air source heat is mainly used in Pump.
As shown in Figure 1, defrosting mechanism 100 is including water receiving part 110 and for warmware 130.Water receiving part 110 includes opposite first Face 111 and the second face 112.In the present embodiment, term " first ", " second " are used for description purposes only, and should not be understood as referring to Show or imply relative importance or implicitly indicates the quantity of indicated technical characteristic.
Specifically, the first face 111 is used for water receiving, in the present embodiment, it can be understood as, the second face 112 is water receiving part 110 Bottom surface.It should be noted that the form and dimension of water receiving part 110 is unlimited, in the art, it is preferable that water receiving part 110 For plate-like.
Include tube body 131 for warmware 130.Tube body 131 is connect with the second face 112, that is, tube body 131 is set to water receiving part 110 bottom surface.It is emphasized that the connection type in tube body 131 and the second face 112 is unlimited, in order to improve stability, this implementation In example, tube body 131 is fixedly connected with the second face 112 of water receiving part 110.Or in other embodiments, being easily installed to be It is detachably connected.
As shown in Fig. 2, tube body 131 includes entrance 132, outlet 133 and the fluid passage (unmarked in figure) of connection.It changes Yan Zhi, tube body 131 can accommodate liquid, and liquid can flow in or out tube body 131.It in the present embodiment, can be in tube body 131 It is inside passed through high pressure low temperature liquid refrigerant, directly to 110 heat supply of water receiving part, ensures at low ambient temperatures, to prevent water receiving part 110 It freezes, and reduces energy loss.
Further, tube body 131 includes sequentially connected first segment 141, second segment 142 and third section 143.First segment 141 and third section 143 along 110 length direction of water receiving part be arranged, third section 143 along 110 width direction of water receiving part be arranged.At this point, It can ensure that each position of water receiving part 110 can obtain heat.It should be noted that in the description of the present embodiment, term " length ", " width " instruction are orientation based on ... shown in the drawings or relative position relation, are not indicated or implied the indicated Equipment or element must have a particular orientation, with specific azimuth configuration and operation.
In conjunction with shown in Fig. 1 and Fig. 2, in the preferable embodiment of the present embodiment, water receiving part 110 includes 113 He of placement section Water-accepting part 114 positioned at 113 both sides of placement section.Wherein, first segment 141 and third section 143 are located at water-accepting part 114.Directly by One section 141 and third section 143, which are set to water-accepting part 114, can significantly improve the efficiency of defrosting.
Preferably, water-accepting part 114 extends from placement section 113, to improve water receiving effect.Or in other embodiments, Water-accepting part 114 is different with the relative altitude of placement section 113.Further, first segment 141, second segment 142 and third section 143 Positioned at same level, the advantages of this arrangement are as follows, facilitate liquid followed by first segment 141, second segment 142 and third Section 143.
It should be noted that in the present embodiment, the shape size and material of tube body 131 are unlimited, it is preferable that first segment 141 and third section 143 be " S " type, second segment 142 be linear type.Since first segment 141 and third section 143 are located at water-accepting part 114 namely first segment 141 and third section 143 be mainly 114 heat supply of water-accepting part, second segment 142 is mainly used for connecting first segment 141 and third section 143.Therefore first segment 141 and third section 143, which are " S " type, can make the flow rate of liquid being located in tube body 131 not As for too fast, retain the heat in tube body 131, improve the efficiency of heat supply.It can ensure liquid when second segment 142 is linear type It smoothly flow to third section 143 from first segment 141.
Preferably, tube body 131 is copper pipe.Copper pipe lighter in weight, thermal conductivity is good, and low temperature intensity is high.And copper pipe have it is firm, Corrosion-resistant equal characteristic, is easily installed simultaneously.
It should be noted that in other embodiments, tube body 131 can be directly of a straight line type set on the second face 112.Or pipe Body 131 is set to the second face 112 in " S " type.That is, tube body 131, which can directly be in " S " type, is set to the second face 112, what is be arranged in this way is good It is on the one hand capable of ensureing that each position of water receiving part 110 can obtain heat;On the other hand can make to be located in tube body 131 Flow rate of liquid be unlikely to too fast, retain tube body 131 in heat, improve defrosting efficiency.
The present embodiment additionally provides a kind of air source heat pump (not shown), including above-mentioned defrosting mechanism 100.Air source heat pump Further include liquid pipe and expansion valve.Entrance 132 is connected to liquid pipe, and outlet 133 is connected to expansion valve.Wherein liquid pipe is mainly high temperature height The liquid pipe of pressure, to provide suitable liquid for warmware 130.
Air source heat pump further includes drainage element 150, and drainage element 150 is connect with water receiving part 110, and drainage element 150 and heat supply The setting of the interval of part 130.At this point, can ensure extra water discharge, and do not influence to work normally for warmware 130.Preferably, it drains Part 150 can improve the heating effect of drainage element 150, defrosting effect is more preferably at this time close to the rebate of " S " type tube body 131.
The operation principle of air source heat pump is:A part of liquid is drawn from the liquid pipe of high temperature and pressure, is entered from entrance 132 To tube body 131, at this point, can prevent water receiving part 110 from freezing 110 heat supply of water receiving part for warmware 130.Final liquid from outlet 133 After returning to expansion valve, liquid cooling supercooling.
Air source heat pump provided in this embodiment is simple to operation, it is ensured that at low ambient temperatures, stable, water receiving There is not icing phenomenon in part 110, reduces energy loss, while also adding the heating capacity of net for air-source heat pump units.In addition, with logical It is often directly laid with electrical heating in water receiving part 110 to compare, air source heat pump provided in this embodiment not only can guarantee water receiving part 110 not It freezes, while energy dissipation and control cost will not be increased.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation Or replace, it should be covered within the scope of the utility model.
