A heater 40 is arranged on the inner side of a heat exchanger 20 arranged inside a host machine body 10 of the air conditioner, so that heat insulation materials 21 of the utility model are not deteriorated, the heater 40 is not easy to rust, and the air conditioner has high heat resistance, high durability and high reliability.

Description

The roof-mounted air-condition device

The utility model is relevant for the roof-mounted air-condition device that disposes heater.

The roof-mounted air-condition device is practical.This aircondition disposes metal tetragonal shell usually, is provided with the drain pan of the water that motor, fan, heater, heat exchanger, reception drip from heat exchanger etc. in the middle of it.

Above-mentioned heater and heat exchanger are located in the main body of aircondition, and each is crooked in the form of a ring.By the rotation of motor drives turbofan, indoor air is inhaled in the main body of aircondition, passes through heater and heat exchanger then, and air is cooled (summer), or is heated (winter), is blown to indoor again.

Above-mentioned heater promptly is located at the ventilation direction downstream of heat exchanger if in the outside of heat exchanger, and heat can directly be emitted on the heat-barrier material that is attached to the shell inner face.Heat-barrier material has hear resistance usually, can degradation but be heated for a long time.And heater in when refrigeration because the generation of the effect of cold wind can cause that dewfall is got rusty etc. problem.

The purpose of this utility model is to provide a kind of have sufficient heat-resisting structure and the aircondition durable, that reliability is high.

The ventilation direction upstream side of the heat exchanger of configuration is provided with heater in the aircondition of the present utility model, its main body.

Under this structure, heater configuration is in the upstream side of the ventilation direction of heat exchanger, and promptly between heat exchanger and fan, the heat-barrier material that therefore is attached to the shell inner face is not subjected to the influence of heater.And heater is not subjected to pass through the influence of the cold wind of heat exchanger yet when refrigeration.

So, can provide a kind of and can not make the heat-barrier material deterioration, heater self also is not easy the aircondition that gets rusty.

In addition, heater is installed in aircondition main body sheath top plate, and heater is supported securely by sheath top plate, so durability is also fine.

In this case, the installing hole of heater and the rectification that is fixed on the sheath top plate inner face are common hole with the installing hole of surface plate, so the quantity in hole can reduce, operation can be simplified.

Preferred embodiment of the present utility model is described with reference to the accompanying drawings, in the accompanying drawing:

Fig. 1 is the structure side view of aircondition of the present utility model.

Fig. 2 is the structure cutaway view of this aircondition.

Fig. 3 is the drawing of seeing from aircondition main body top, is the state that removes behind sheath top plate and the inner face heat-barrier material.

Fig. 4 is the stereogram of heater.

Fig. 5 is the heater view of seeing from below on the sheath top plate of being fixed on, and this figure has omitted decoration panel, drain pan, horn mouth and turbofan.

Fig. 6 is the cutaway view of cutting open along the a-a line of Fig. 5, represent state on the sheath top plate that heater is installed to.

Fig. 1 is the concise and to the point side view of structure that the roof-mounted air-condition device of heat exchanger and heater is equipped with in the inside.Four-sided openings 2 is arranged on ceiling 1.Air conditioner main body 10 enters into ceiling inboard 4 by indoor 3 by opening 2.Begin main body to be lifted in ceiling inboard 4 from beam 5 sagging suspension rods 6 then by metalwork 14 in ceiling inboard 4.Main body 10 is installed decoration panel 50 again below main body 10 after the lifting that is done.Decoration panel 50 covers the profile of the opening 2 of ceiling 1, from the indoor opening 2 of can't see.

Fig. 2 is the cross-sectional configuration figure of aircondition.Fig. 3 is the plane of seeing from main body 10 tops, is the state behind omission sheath top plate 16a and the inner face heat-barrier material 21.

Describe below with reference to Fig. 2 and Fig. 3.Constitute main body 10 profile be shell 15.The below of shell 15 is open metallic plate system quadrangle case shape, and is made up of top board 16, side plate 16a.Dispose the motor 17 that is fixed on sheath top plate 16 central authorities in the shell 15, by the turbofan 18 of motor 17 rotations, horn mouth 19 that the guiding air flows into turbofan 18, near the heater 40 around the turbofan 18, around the heat exchanger 20 of heater 40 and the drain pan 30 that receives the water that drips from heat exchanger 20.Water in drain pan 30 is sucted after be discharged to outdoor by drainpipe 26 by draining pump 25.Heat exchanger 20 is connected by refrigerant pipe 27.

In addition, on sheath top plate 16a, be formed with ribs groove 16e as shown in Figure 5, so air can cause the flow direction disorderly because of flowing through the rib groove, so below sheath top plate 16a, be connected to the panel beating surface plate 16c (with reference to Fig. 2, Fig. 6) of rectification air effect.

On the periphery of the top board 16a of shell 15 and the inner peripheral surface of side plate 16b, make the outer surface dewfall of shell 15, embedded the inner face heat-barrier material made from Foamex etc. 21 for not making the air that carries out heat exchange by heat exchanger 20.

Decoration panel 50, its central portion have the suction inlet 51 that can suck air in a large number, and its periphery is an air blow-off outlet 52.Dispose the air cleaner 53 of catching dust in the air above the air suction inlet 51.

Running to above-mentioned air conditioner is done an explanation.By 18 rotations of motor 17 turbofan, room air such as hollow arrow indication by air suction inlet 51, are inhaled into main body 10 and blow to heater 40, heat exchanger 20.Be cooled (summer) or be heated (winter) by heater 40, heat exchanger 20 air, have for another example shown in the arrow of hatching, the air blow-off outlet 52 by decoration panel 50 around the main body 10 is blown to indoor.

Fig. 4 is the stereogram of the heater 40 seen from oblique below.For making heater 40 base volumes around turbofan 18, bending forming has a plurality of tubulose heaters 41.Heater 40 disposes metalwork 42 is installed for heater 41 is fixed on the sheath top plate 16a.

Fig. 5 is heater 40 views of seeing from below on the sheath top plate 16a of being fixed on, and this figure has omitted decoration panel 50, drain pan 30, horn mouth 19 and turbofan 18.

Heater 40 promptly is disposed at ventilation direction upstream side in the inboard of heat exchanger 20, by metalwork 42 is installed, is screwed on sheath top plate 16a.

Distance between heater 40 and the turbofan 18, the minimum about 25mm in place.Decision 25mm this digital reason is: if the distance between heater 40 and the turbofan 18 is extremely reduced, can produce 1. resin thermal deformation as the material of turbofan 18, and the big problem of sending when 2. blowing of sound change.

Minimum range between heater 40 and the heat exchanger 20 is about 25mm.

The electrode wires 43 of the heater 40 of drawing from the end of heater 41 connects circuit board in the main body 10, that dispose (figure does not show) by the cut-in groove 21f guiding that is formed on the inner face heat-barrier material 21 below refrigerant pipe 27.

Fig. 6 is the cutaway view of cutting open along the a-a line of Fig. 5.On sheath top plate 16a, be provided with hole 16d.Use on the surface plate 16c in above-mentioned rectification, on the position the same, also have hole 16g with 16d.The installation metalwork 42 of heater 40 is fixed on the sheath top plate 6a with bolt 44 by these holes 16d, 16g.In addition, the 16f of Fig. 6 demonstration is attached to the lip-deep Foamex system sound-absorbing material of surface plate 16c.

The aircondition that produces with present design, the ventilation direction upstream side of the heat exchanger that disposes in its main body is provided with heater, therefore can realize not deterioration of heat-barrier material, heater self be not easy to get rusty structure, hear resistance, durability, air conditioner that reliability is high.
