Abstract

An electric supporting heater for air conditioners comprises a strip shaped electric heating rod, a heat dissipation sheets group which is sleeved on the electric heating rod and tightly pasted to thereof, and an insulation bracket which is fixed at both ends of the electric heating rod. The utility model is characterized in that another connecting hole which is approximately paralleled with the electric heating rod is arranged on the heat dissipation sheets group, the extraction wire at one end of the electric heating rod passes through the connecting hole and locates at the same side with the extraction wire of the other end of the electric heating rod. A guide tube is preferably arranged in the connecting hole of the heat dissipation sheets group. The extraction wire of the electric heating rod passes through the guide tube and reversely folds. The heat dissipation sheets group is preferably formed by singly separated single heat dissipation sheet which is connected in series, and each of the heat dissipation sheet provides a heave at one side so as to keep interval with other adjacent heat dissipation sheets. The heat dissipation sheet preferably has a shape like half moon. Therefore, compared to the existing technique, due to that that the extraction wires of both sides of the electric heating rod are at the same side, assemble is very convenient. Meanwhile, the design of half moon shaped heat dissipation sheet is capable of using the internal space of air conditioners better.

Description

A kind of air-conditioning electric heating device

Technical field

The utility model relates to a kind of parts of air-conditioning, particularly a kind of air-conditioning electric heating device.

Background technology

The existing domestic air conditioning overwhelming majority is two-way, promptly can freeze and can heat, yet be limited to the restriction that heats circulation itself, and the height during not as refrigeration of the operating efficiency when heating is particularly at cold district.Therefore, need be equipped with electric heating device toward contact.Existing electric heating device generally comprise strip heating sucker rod, be enclosed within its outer and the groups of fins be close to it and insulating support that is fixed on its two ends, wherein the two ends of heating sucker rod need lead and draw, yet because the two ends of the lead office heating sucker rod of being drawn are very inconvenient when assembling.Because the space in the heating sucker rod is limited, and heating during work, therefore, if be infeasible directly through inner inflection to the other end of heating sucker rod with the lead of drawing of an end.In addition, because the air-conditioning inner space is limited, how rationally utilizing existing air-conditioning inner space also is the problem that manufacturer was concerned about.

Summary of the invention

Technical problem to be solved in the utility model be how a kind of heating sucker rod two ends to be provided draw the air-conditioning electric heating device of lead in the same side.

Another technical problem to be solved in the utility model is how a kind of air-conditioning electric heating device that can effectively utilize the air-conditioner inner space is provided, and makes it bring into play maximum effect to greatest extent.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the air-conditioning electric heating device include strip heating sucker rod, be enclosed within its outer and the groups of fins be close to it and insulating support that is fixed on its two ends, it is characterized in that described groups of fins also has the through hole of another and heating sucker rod almost parallel, the heating sucker rod wherein lead of drawing of an end passes this through hole, is in position, the same side with the lead of drawing of the heating sucker rod other end.

Described groups of fins through hole is interior to be good so that a conduit to be set, and the lead of drawing of described heating sucker rod promptly passes this conduit inflection.

For cooperating the heating sucker rod of different length, described groups of fins conspires to create to good with the single fin by each self-separation, and each fin one side has projection, so that all the other adjacent fin keep at interval; Wherein be best with the following proposal, two through holes that promptly described fin is used for running through heating sucker rod and draws lead have the edge to outer lug.

Described fin is best with the semilune, with the inner installation position of the air-conditioning that cooperates its place.

Compared with prior art and since heating sucker rod of the present utility model two ends draw lead in the same side, therefore assemble very conveniently, simultaneously, the design of semilune fin more can make full use of the inner space of air-conditioner.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 5, the air-conditioning electric heating device include strip heating sucker rod 2, be enclosed within its outer and 3 groups of fin being close to it and insulating support 1 that is fixed on its two ends, referring to Fig. 1, Fig. 3;

Fin 3 is semilune, have two through

holes

31,32 on it, and the periphery in hole has the edge to outer lug, referring to Fig. 4, Fig. 5, so that adjacent fin keeps at interval, form two parallel passages simultaneously, referring to Fig. 2, heating sucker rod 2 promptly passes one of them passage 31, in another passage 32, then be installed with a conduit 4, the lead 22 of drawing of heating sucker rod 2 right-hand members promptly passes this conduit 4 inflection, with heating sucker rod 2 left ends draw lead 21 exist together the left side, referring to Fig. 1, Fig. 3.

Certainly heating sucker rod 2 right-hand members draws lead 22 and also can directly pass passage 32 inflection and need not conduit 4.

Claims

1, a kind of air-conditioning electric heating device, include strip heating sucker rod, be enclosed within its outer and the groups of fins be close to it and insulating support that is fixed on its two ends, it is characterized in that described groups of fins also has the through hole of another and heating sucker rod almost parallel, the heating sucker rod wherein lead of drawing of an end passes this through hole, is in position, the same side with the lead of drawing of the heating sucker rod other end.

2, air-conditioning electric heating device according to claim 1 is characterized in that being provided with a conduit in the described groups of fins through hole, and the lead of drawing of described heating sucker rod promptly passes this conduit inflection.

3, air-conditioning electric heating device according to claim 1 and 2 is characterized in that described groups of fins is conspired to create by the single fin of each self-separation, and a side of each fin has projection, so that all the other adjacent fin keep at interval.

4, air-conditioning electric heating device according to claim 3 is characterized in that described fin, and two through holes that run through heating sucker rod and draw lead have the edge to outer lug.
