Abstract
Interior unit of an air conditioner that consists of an outer framework, equipped with an exchanger for exchanging its heat with the air drawn from its interior, a fan to impel air from the outside into the inside of the chamber and discharge air from the chamber to the outside, and a motor to run the fan. The motor is lodged in a housing. The housing insulates the motor from the heat exchange chamber. In this way, the air cooled by the exchanger is not heated by the air generated by the motor, and this increases the cooling efficiency of the air conditioner.
Description
The present invention relates to a kind of indoor unit of air-conditioner, more particularly, relate to a kind of like this air-conditioner, wherein be used for the motor of drive fan and heat-exchanging chamber separates so that the reduction of the refrigerating efficiency that prevents to cause because of the motor feels hot.
An air-conditioner has an indoor unit and an outdoor unit that is installed in outside the room that is installed in the room usually.Outdoor unit has the compressor that is used for compression refrigerant and is used for the outdoor heat converter of the refrigerant that condensation compressed by compressor.This indoor unit has indoor heat converter and produces cold air by the refrigerant that evaporates by the outdoor heat converter condensation.
Fig. 4 and Fig. 5 show an example of the indoor unit of air-conditioner, and air-conditioner indoor unit 50 has the outer cover 51 and an indoor heat converter 57 and the blowing device 58 that is installed in the heat-exchanging chamber 54 that form heat-exchanging chamber 54.Outer cover 51 comprises a front shroud 53 and a back cover 52, and suction inlet 55 is formed on the front portion of front shroud 53, and outlet 59 is formed on the lower region of front shroud 53.Blowing device 58 is pumped into extraneous air in the heat-exchanging chamber 54 by suction inlet 55, and the air in the heat-exchanging chamber 54 is discharged through outlet 59.
When air-conditioner was worked, cross flow blower 58a and 58b were by drive motors 70 driven rotary, and therefore room air is pumped in the heat-exchanging chamber 54 by suction inlet 55.Indoor heat converter 57 carries out heat exchange with the air of institute's suction, thereby air is cooled in heat-exchanging chamber 54, and cooled air is discharged through outlet 59.
In such air-conditioner, along with the continuous firing of indoor unit 50, heat is produced by drive motors.Because drive motors and indoor heat converter 57 together are installed in the heat exchanger chamber 54, the air by indoor heat converter 57 coolings is driven hot heating that motor 70 produces again, thereby the integrally cooling efficient of air-conditioner reduces.
Proposition of the present invention is to overcome the problems referred to above of the prior art, therefore the object of the present invention is to provide a kind of indoor unit of air-conditioner, can be by preventing to improve cooling effectiveness because of the drive motors heating heats up heat-exchanging chamber.
For achieving the above object, the invention provides a kind of indoor unit of air-conditioner, comprising: one constitutes the outer cover of heat-exchanging chamber; One is installed in the heat exchanger in the heat-exchanging chamber, is used for carrying out heat exchange with the air that is pumped in the heat-exchanging chamber; One is installed in the fan in the heat-exchanging chamber, and this fan is used for extraneous air being pumped into heat-exchanging chamber and the air in the heat-exchanging chamber being discharged to outside the heat-exchanging chamber; One CD-ROM drive motor that is used for drive fan; And a holding portion that is used to hold drive motors, so that drive motors and heat-exchanging chamber are separated.
The described accommodation section is recessed into to the inboard of heat-exchanging chamber by the back middle part with outer cover and forms.Both sides in the accommodation section are formed with axis hole, and the axle of drive motors passes this hole.The described accommodation section is preferably half-cylindrical.
A lid that is used to cover the accommodation section opening is installed in the outside of outer cover, describedly is stamped a plurality of passages.
The present invention has prevented the reduction of the air-conditioner refrigerating efficiency that the heating because of CD-ROM drive motor causes.
The explanation of being done in conjunction with the drawings, various purposes of the present invention and advantage will be better understood.
Fig. 1 is the sectional side view of air-conditioner indoor unit;
Fig. 2 is the decomposition diagram of Fig. 1;
Fig. 3 is that transverse sectional view is amplified in the part of the assembled state of Fig. 2;
Fig. 4 is the sectional view of the indoor unit of air-conditioner prior art;
Fig. 5 is the decomposition diagram of Fig. 4.
Below in conjunction with accompanying drawing the present invention is described in detail.
Fig. 1 to Fig. 3 shows according to air-conditioner indoor unit of the present invention.
The indoor unit 10 of air-conditioner has one and constitutes the outer cover 1 of heat-exchanging chamber 4 and be installed in indoor heat converter 7 in the heat-exchanging chamber 4.Outer cover 1 comprises a front shroud 3 and a back cover 2.Suction inlet 5 is formed on the front side of front shroud 3, and outlet 9 is formed on the lower position of front shroud 3.
Fan 8 is installed in the heat-exchanging chamber 4, and fan 8 is made up of pair of cross airflow fan (crossflowfan) 8a and 8b.Fan 8 is pumped into extraneous air in the heat-exchanging chamber 4 through suction inlet 5, and through outlet 9 air in the heat-exchanging chamber 4 is discharged to the outside.
The lid 25 that is used to cover the opening of accommodation section 30 is installed in the rear side of back cover 2, is formed with a plurality of screw holes 27 on lid 25, and is formed on the back cover 2 with screw hole 27 corresponding assemblies 32.By screw hole 27 screw 28 is assembled on the assembly 32, covers 25 and be installed on the back cover 2, on the lid 25 a plurality of passages 26 are arranged thereby make.
When air-conditioner is worked, cross flow blower 8a and 8b are by drive motors 20 driven rotary, thereby room air is drawn in the heat-exchanging chamber 4 through suction inlet 5, and indoor heat converter 7 carries out heat exchange with the air that is drawn into, and air is cooled in heat-exchanging chamber 4 like this.Cold air is discharged through outlet 9.
Separate by accommodation section 30 and heat-exchanging chamber 4 owing to be used for holding the space of drive motors 20,, therefore improved the cooling effectiveness of air-conditioner so can not be heated because of the heat that drive motors produces by the air of indoor heat converter 7 coolings.Simultaneously, because the inner space of accommodation section 30 can ventilate by the air vent through covering on 25, so the inner space of accommodation section 30 can not overheat because of the heating of drive motors 20.
As mentioned above, according to the present invention, can prevent the reduction of the air-conditioner cooling effectiveness that the heating owing to drive motors 20 causes.
Although the present invention is had been described in detail, should be understood that above-mentioned explanation only is exemplary, and be not construed as limiting the invention.Spiritual essence of the present invention and scope are only pushed up by the money of appended claims and are limited.
