Description

The indoor unit of air-conditioning

The application requires to be submitted on July 14th, 2004 interests of the 2004-54837 korean patent application of Korea S Department of Intellectual Property, and this application all is disclosed in this, for reference.

Technical field

The present invention relates to a kind of indoor unit of air-conditioning, more particularly, relate to a kind of mounting structure of fan electromotor of indoor unit of wall-hanging air conditioner.

Background technology

Usually, air-conditioning uses kind of refrigeration cycle to cool off or heats the interior space, and the indoor unit of air-conditioning comprises heat exchanger, is used for and room air exchanged heat; Fan, thus be used to produce the power of mobile room air by heat exchanger; And fan electromotor, be used to drive this fan.

Publication number be 2003-262354 Japanese patent publication the mounting structure of traditional fan electromotor.Disclosed as above-mentioned file, the motor fixed cell that is used to hold fan electromotor with semi-circular cross-sections is formed on the substrate of the rear surface that constitutes casing, and under fan electromotor is installed in situation on the motor fixed cell, the motor cover of fan electromotor is fixed to the motor fixed cell by using locking component, thus fan electromotor is fixed in the substrate.

Thereby under situation in the indoor unit of the air-conditioning that heat exchanger is installed in the above-mentioned mounting structure with fan electromotor is vertically erect in substrate, fan electromotor reduces the packaging efficiency of indoor unit thus because the weight of fan electromotor can break away from from substrate.In addition, under the situation of air-conditioning quilt operation, when motor cover when substrate breaks away from, fan electromotor causes the fault of indoor unit thus because the weight of fan electromotor breaks away from from the motor fixed cell.

Summary of the invention

Therefore, an aspect of of the present present invention provides a kind of indoor unit of air-conditioning, and the mounting structure of fan electromotor is enhanced therein, has the packaging efficiency of improvement thus and is easy to be operated.

According on the one hand, the invention provides a kind of indoor unit of air-conditioning, comprising: fan is used for sucking and the discharging room air; Fan electromotor is used for drive fan; Substrate is provided for holding the motor holding tank of fan electromotor; And ribs, arrange with the motor holding tank to be used for the supports fan motor contiguously.

Thereby ribs can be positioned at the front at the center of fan electromotor from an end of each ribs of substrate extension.

In addition, the contact surface of each ribs of contact fan electromotor can up tilt to an end of its extension from its fixing end.

And ribs can be configured to the both sides of supports fan motor.

Indoor unit can also comprise the motor cover of the front surface that is used to hide fan electromotor.

In addition, being used to allow ribs can pass motor cover by it with the through hole that passes motor cover forms.

Fig. 4 is the cutaway view of the mounting structure that obtains along the line IV-IV among Fig. 3.

The specific embodiment

To describe embodiments of the invention in detail now, its example shows that in the accompanying drawings wherein, identical label is represented identical parts all the time.Below, by describing embodiment with reference to the accompanying drawings to explain the present invention.

As shown in Figure 1, the indoor unit of air-conditioning according to a preferred embodiment of the invention comprises substrate 30, constitutes the rear surface of casing; Front baffle 12 is placed on the front surface of substrate 30 and is provided for sucking opening and the preceding grid 10 that sucks room air by it, and the front that is installed in front baffle 12 is used for sucking air by its front surface and upper surface.

Air air filter 11 before placing between grid 10 and the front baffle 12 filters away impurity from inhaled air.The heat exchanger 20 that comprises a plurality of wings (pin) that pile up abreast and the refrigerator pipes by wing is installed in the front baffle 12.The phase transformation of the cold-producing medium of heat exchanger 20 by passing refrigerator pipes absorbs or emits latent heat, cooling or heating room air thus.The cross flow fan 21 that is used to produce the suction or emit the power of room air is installed in the inboard of heat exchanger 20.Cross flow fan 21 is installed in the substrate 30 with horizontal direction, and the fan electromotor 22 that is used to drive cross flow fan 21 is installed in an end of cross flow fan 21.

Substrate 30 comprises the motor holding tank 32 that is used to guide the back guider 31 of room air of being introduced by cross flow fan 21 and the room air that discharges guiding downwards and is used for holding therein fan electromotor 22.The motor cover 23 that is installed in the front surface of fan electromotor 22 by being used to hide fan electromotor 22 in the motor holding tank 32 is fixed to substrate 30.

Comprise that the electric assembly housing 24 of the circuit of the operation that is used to control indoor unit is installed in the top of fan electromotor 22.

Below, with reference to Fig. 2 to Fig. 4, will describe the mounting structure of fan electromotor 22 in detail.

Thereby it is corresponding with the outer surface of fan electromotor 22 that the motor holding tank 32 that is formed on a side of substrate 30 has the circular arc cross section.The ribs 33 that is used for the bottom, two ends of supports fan motor 22 is formed on the bottom of motor holding tank 32.As shown in Figure 4, thus the end that ribs 33 is extended ribs 33 from substrate 30 is positioned at the front at the center of fan electromotor 22.Therefore, though under the situation that substrate 30 is vertically erect as shown in Figure 2, motor cover 23 breaks away from from the front surface of fan electromotor 22, and ribs 33 can prevent that fan electromotor 22 breaks away from from motor holding tank 32.Preferably, as shown in Figure 4, the contact surface of each ribs 33 of contact fan electromotor 22 is inclined upwardly to an end of its extension from its fixing end.The said structure of ribs 33 makes fan electromotor 22 more closely contact with the inside of motor holding tank 32 by the weight of fan electromotor 22.

Fan electromotor 22 fixing by the front surface that fan electromotor 22 is installed in the motor holding tank 32 and hide fan electromotors 22 with motor cover 32 then in substrate 30 is done.Motor cover 32 is fixed in the substrate 30 by locking component such as screw.In order to prevent that ribs 33 from hindering motor cover 23 fixing in substrate 30, thereby through hole 23a is formed on corresponding to the position ribs 33 of the motor cover 23 of ribs 33 and passes motor cover 23 by through hole 23a.

Be clear that from the above description, the invention provides a kind of indoor unit that comprises the air-conditioning of ribs, thereby the bottom of this ribs supports fan motor when fan electromotor by with substrate assembling or operation of air conditioner the time, weight by fan electromotor prevents that fan electromotor breaks away from from the motor holding tank, improves assembling thus and drives efficient.

Although show and the description embodiments of the invention, it should be appreciated by those skilled in the art, not breaking away under principle of the present invention, spirit and the situation, can make a change in an embodiment by claims and equivalent institute restricted portion thereof.
