Abstract

The utility model relates to a wall hanging type air conditioner, which comprises a casing, a motor arranged on a motor installing frame arranged in the casing and wind wheels arranged on motor shafts. The utility model is characterized in that the two wind wheel are symmetrically installed and tightly fixed to the motor shafts extended out from both ends of the motor and are supported by two bearings of the motor. The air conditioner is mainly characterized in that the structural form of a running part of the wall hanging type air conditioner, namely, the motor installing mode of the wall hanging type air conditioner is changed from that the motor is arranged at the end part to that the motor is arranged at the middle part; the installing mode of the wind wheel is changed from that a long wind wheel is arranged on one side shaft of the motor to that the two short wind wheels are symmetrically arranged at the shafts extended out from the both ends of the motor; the three bearings of the running part of the existing wall hanging type air conditioner are changed into two bearings, and the running part of the wall hanging type air conditioner is supported by the two bearings of the motor; the problem that the three points of the running part are eccentric is thoroughly solved, and the utility model has the advantages of friction reduction, power consumption reduction, noise reduction, maintenance reduction, long service life for the air conditioner, high running quality and high reliability.

Description

Wall air conditioner

Technical field

The utility model relates to field of air conditioning, and particularly a kind of end-equipment of field of air conditioning---wall air conditioner is commonly called as wall-hanging fan coil.

Background technology

Air-conditioner is the electric equipment that people use always, wall air conditioner owing to its good looking appearance, volume is less, easy for installation and do not take up an area of characteristics such as face area is widely used in detachable air conditioner and central air conditioner system.Because the wall air conditioner volume is less, rotor diameter is also less, in order to guarantee air output, requires the length of wind wheel longer.The version of wall air conditioner all is the end that motor is installed in air conditioner at present, a long wind wheel is installed on the axle of motor one side, so just make machinery by three bearings, it is two in motor itself, the other end of wind wheel also has one, and three bearings cause decentraction easily, causes that bearing friction power increases, the wind wheel operation is not steady, thereby cause heating, distortion and produce the operation noise, directly influence the service life and the service property (quality) of wall air conditioner.

Summary of the invention

The purpose of this utility model is just at the problem of 3 decentraction of above-mentioned existing in prior technology machinery and custom-designed a kind of wall air conditioner, use this air conditioner, can reduce operation noise and power attenuation, minimizing even release maintenance workload, increase the service life, improve running quality.

The purpose of this utility model realizes in the following manner:

This wall air conditioner comprises housing, be installed in the motor on the motor installing rack in the housing and be installed in wind wheel on the motor shaft, wherein: two wind wheel symmetries are installed on the motor shaft that stretches out at the motor two ends, rely on two bearings of motor, when being the motor rotation, directly driving two wind wheels and rotate.

In the utility model, in order further to reduce the operation noise, motor is installed on the motor installing rack on the housing base plate, and is provided with damper between motor and installing rack, damper is generally the damper that elastomeric material is made, and also available other is suitable for the material of damping; The installation and removal of motor for convenience, motor can adopt the motor of arcuate structure fixedly to fasten on installing rack.

Main feature of the present utility model is the version that changes the wall air conditioner machinery, promptly the electrical installation of wall air conditioner, by the end motor is installed, and changes the middle part into motor is installed; The mounting means of wind wheel, install on motor one side shaft by a long wind wheel, making on the axle that two shorter wind wheels stretch out in the motor both sides symmetry into installs, three bearings of present wall air conditioner machinery, change two bearings into, promptly rely on the machinery of two bearings wall air conditioners of motor, thoroughly solved the problem of 3 decentraction of machinery, reduce friction, reduced power consumption, reduced noise, reduced maintenance, prolong the service life of wall air conditioner, improved running quality and reliability.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 1, i.e. the partial view of motor installation.

Fig. 4 is the B-B cutaway view of Fig. 3.

The specific embodiment

The utility model is further described below in conjunction with accompanying drawing:

Shown in Fig. 1,2,3,4: this wall air conditioner comprises the wind wheel of installing on housing (13), motor (8), the motor two end axles (3), motor is in the middle part of complete machine substantially, two wind wheels (3) symmetry is installed and is fixed tightly on the motor shaft (4) that stretches out at the motor two ends, relies on two bearings (5) of motor to support.Motor (8) is installed on the motor installing rack (12) on the housing base plate (1), and is provided with damper (2) between motor and installing rack.For making things convenient for the installation and removal of motor, can adopt the fixedly card (7) of arcuate structure that motor (8) is fixed on the installing rack (12).For preventing the resonance of motor when operation base plate, can strengthen the intensity and the thickness of base plate (1).Motor shaft (4) should have enough rigidity, length and concentricity, to prevent to turn round time distortion; Because mechanism's installing space is limited, the external diameter of motor (8) should not be greater than the diameter of wind wheel (3).

Number in the figure (6) is for preventing the Spring Card of motor shaft play, and (9) are the complete machine return air inlet, and (10) are the complete machine air outlet, and (11) are heat exchange coil.

Claims

1, a kind of wall air conditioner, it comprises housing (13), be installed in the motor (8) on the motor installing rack in the housing and be installed in wind wheel (3) on the motor shaft (4), it is characterized in that: two wind wheels (3) symmetry is installed on the motor shaft (4) that stretches out at the motor two ends, relies on two bearings (5) of motor (8) to support.
