Description

Air Conditioner {AIR CONDITIONER}

The present invention relates to a treatment structure for condensation water which is produced and attached to, for example, an air conditioner, in particular a blower support, which is an indoor unit, and eventually enlarges and flows down.

In the indoor unit constituting the air conditioner, the indoor heat exchanger and the indoor blower are disposed to face each other in the unit main body which is the air conditioner main body.

The indoor blower sucks air into the unit body through the suction port installed in the unit body, heats through the indoor heat exchanger, and then blows out the air outlet from the air outlet installed in the unit body through the indoor blower to the air chamber. .

In addition, the indoor blower is composed of a cross flow fan and a fan motor connected to one end of the cross flow fan, both ends of the cross flow fan are supported by a support that is a bearing member relative to the unit body, and the motor fan is a motor band by the unit body. Is supported.

However, in this type of air conditioner, when the cooling operation is performed, the cold heat exchanged in the indoor heat exchanger is led to the outlet through the indoor blower, so that the cross-flow fan, the fan motor, the support, the motor band, and the like of the blower are in contact with the cold air. It is cooled to below the dew point, and condensation water is easily generated.

However, since the crossflow fan is rotationally driven, no dew condensation water is generated on the surface thereof, and the fan motor generates heat to some extent in accordance with the operation.

That is, condensation water is not substantially generated in the crossflow fan and the fan motor, and heat of the fan motor is transferred to the motor band so that condensation water is not generated.

As a result, the support for supporting the crossflow fan is not rotationally driven and is not a heating element. Therefore, the dew condensation water is easily generated, enlarges with time, and flows down when it reaches a predetermined amount or more. The condensation water is carried by the cold air passing through the blower to the outlet, and there is a fear of scattering or falling into the air-conditioning room from there.

Therefore, in the conventional indoor unit, the back surface is attached to the support body and its surroundings so as not to contact the cold air, or the back surface is provided on the unit body so that no condensation water falls to the outside of the main body.

However, in consideration of formability, use, and cost, PP is generally used, and in order to attach a heat insulating material to the support, a special adhesive is required, and a heat insulating material, a special adhesive, and a process water are required, which adversely affects the cost.

Moreover, even if a simple receiving surface is provided in the unit main body, a water-retaining structure cannot be obtained, but there exists an unreasonable effect, for example, the dew condensation falls outside the unit main body by the negative pressure action accompanying rotation of a crossflow fan.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its object is to achieve optimum air conditioning by preventing scattering or falling from the air outlet to the outside even when condensation water is generated and flowed into a support supporting the blower. And to provide an air conditioner that contributes to a reduction in material costs and costs.

The air conditioner is divided into an indoor unit and an outdoor unit (not shown) and connected through a refrigerant pipe. The indoor unit is attached and fixed to the upper wall of the air conditioning chamber, the outdoor unit is installed outdoors.

The unit main body 1, which is an air conditioner main body of an indoor unit, is covered with a suction grill 3 over its entire surface, and a front panel 2 whose rear side is opened across its front surface, and a rear surface of the front panel 2; It consists of the thick board 4 inserted in the opening part.

The display lamps 5 are provided in the lower part of the front panel 2, and the ejection opening 7 provided with the louver 6 which is an ejection guide in the lower side is opened. In particular, as shown in Fig. 2, the front side of the front panel 2 is a plate-shaped portion 2a, 2b of a cross section in which both left and right sides thereof are curved. The plate-shaped portions 2a and 2b are opened to each other, and a rectangular crosspiece 8 is provided in the opening 2c.

The air filter 9 backed up by the ladder part 8 is detachably attached to the said opening part 2c. Together with the air filter 9, the ladder portion 8 of the unit main body 1 and the two side plate portions 2a and 2b are covered by the suction grill 3. In addition, the upper suction port 10 is opened at an upper portion of the front panel 2 at predetermined intervals.

The rear plate 4 has a substantially L-shaped cross section and is placed in a state in which the indoor heat exchanger 11 and the indoor blower 12 face each other, and at the same time, an electrical parts box 13 is provided on the side of the indoor blower 12. Batch is accommodated.

The indoor heat exchanger 11 is formed in an inverted V shape as viewed from the side, and is composed of a front heat exchanger portion 11A positioned on the front side and a rear heat exchanger portion 11B positioned on the rear side. In particular, an auxiliary heat exchanger portion (not shown here) is disposed along the upper surface of the rear heat exchanger portion 11B.

The front heat exchanger portion 11A is bent in an arc shape when viewed from the side, and the rear heat exchanger portion 11B and the auxiliary heat exchanger portion form a straight shape when viewed from the side. In particular, the upper portion of the front heat exchanger portion 11A is inclined toward the rear side.

Each heat exchanger part 11A, 11B is what is called a finned tube which consists of the several fan F mutually spaced apart by the narrow space | interval, and the heat exchange pipe which penetrates this fan F and is connected in a zigzag shape.

3 is a cross-sectional inverted c-shape at both side ends (only one end shown) of the fin F constituting each heat exchanger part 11A, 1B, and the shape seen from the side of each heat exchanger part. The end plate 14 shape | molded so that it may match is provided, and the said heat exchange pipe P penetrates this end plate 14.

In addition, as shown in FIG. 2, a front drain plate 15 is provided below the front heat exchanger part 11A constituting the indoor heat exchanger 11, and a rear drain plate (under the rear heat exchanger part 11B). 16) is arranged. The before and after drain plates 15 and 16 are integrally molded to the thick plate 4.

The indoor blower 12 is disposed between the front heat exchanger portion 11A and the rear heat exchanger portion 11B. In other words, the front heat exchanger portion 11A and the rear heat exchanger portion 11B with respect to the indoor blower 12 are arranged in an upper portion, and are in a position covered with an umbrella shape.

The indoor blower 12 is disposed on and supported by a cross flow fan 17 on which support shafts (only one support shaft is shown in Fig. 3) 17a protrudes on both side ends, and on one side end of the cross flow fan 17. A fan motor 18 to which its rotating shaft is connected via a shaft and a coupling not shown, and a support 20 disposed between the fan motor 18 and the cross flow fan 17 and at the other end of the cross flow fan 17, respectively. It is composed of

Each support 20 has a predetermined thickness and is provided with a bearing member (not shown) therein, and rotatably supports the support shaft 17a protruding from both side ends of the cross flow fan 17. Each support body 20 has the same structure, and only one side is shown in FIG. 4, and the other support body 20 is abbreviate | omitted by applying the same figure.

On the side of the crossflow fan 17 which is the inner surface side of this support body 20, the semicircular dew receiving body 21 is provided in the lower part rather than the crossflow fan 17 axis center.

The dew receiving body 21 is provided along the housing portion 22 which protrudes integrally from the side wall of the support 20 and the side edge of the housing portion 22 so as to be parallel to the side wall of the support 20. Consists of a hill 23 to protrude.

From this, the dew receiving body 21 is integrally formed with respect to the support body 20, and the semicircular recessed groove is formed along the inner surface side lower part of the support body 20. As shown in FIG.

In addition, both side ends of the cross flow fan 17 extend to the opposite position of the housing portion 22 through the hill 23 of the dew receiver 21, and the end plate 17b is located in the housing portion 22.

When the indoor unit of the air conditioner configured as described above and the start instruction of the air conditioning operation is issued, the indoor blower 12 is driven at the same time as the refrigeration cycle operation for the indoor heat exchanger (11).

That is, the cross flow fan 17 is rotated so that the air inside the air-conditioning chamber is sucked into the unit main body 1 through the opening 2c, which is the front suction port of the front panel 2, and the upper surface suction port 10.

This air is led to the rear heat exchanger portion 11B through the front heat exchanger portion 11A and the auxiliary heat exchanger portion and undergoes heat exchange when passed therethrough. At the time of cooling operation, it is switched to cold, is drawn out from each heat exchanger part 11A, 11B, is guided to the outlet 7 through the indoor blower 12, and it is taken out from this to the air-conditioning room, and it performs cooling operation.

In addition, the site | part during which cooling air derived from the indoor heat exchanger 11 is guide | induced to the blower outlet 7 through the indoor blower 12 at the time of cooling operation becomes cool and it becomes below a dew point. Therefore, in that state, moisture contained in cold air condenses and turns into condensation water.

By the way, since the crossflow fan 17 is rotationally driven, condensation water does not adhere. The fan motor 18 is accompanied by a certain heat generation action by the drive, and at the position not facing the indoor heat exchanger 11, since no cold air passes, condensation water is not generated.

As a result, the cool air drawn from the indoor heat exchanger 11 is brought into contact with the support 20, and condensation water is generated from the time of cooling it. In detail, the support body 20 has a predetermined thickness, and only the inner surface side of the support body 20 is in contact with cold air, and condensation water is generated.

The condensation water generated on the inner surface side of the support 20 enlarges with time and eventually flows along the inner surface wall. In this state, it flows to the vicinity of the outlet 7 and is carried by cold air discharged from the outlet 7 to fly or fall into the air-conditioned chamber, where the dew receiver 21 provided on the inner surface side of the support 20 is here. Is received in.

That is, the dew condensation water is guided in the dew receiver 21 and collected therein. Since the side wall of the support body 20 and the housing portion 22 and the hill portion 23 form a cross-sectional concave groove shape, a sufficient amount of condensation water is collected and does not overflow to the outside.

In addition, even if the condensation water may be generated and flowed into the crossflow fan end plate 17b while the cooling operation is stopped, the end plate 17b is located in the housing part 22 of the dew receiver 21, All are received by the housing part 2 and do not leak outside.

Therefore, comfort air conditioning is ensured without condensation water flying or falling from the air outlet 7 to the air-conditioning chamber. Since the dew receiver 21 is integrally molded with the support 20, it is advantageous in terms of cost and does not require molding effort.

In addition, in the said embodiment, although the dew receiver 21 was provided in each support body 20 inside the cross-flow fan 17 both side ends, it is not limited to this, The dew receiver 21 is a fan motor. You may integrally shape only the inner surface of the support body 20 of the non-fan motor 18 side, without providing it in the inside surface of the support body 20 of the (18) side.

That is, as described above, the fan motor 18 generates heat even in a cooling operation and does not directly generate condensation water. The heat is transmitted to the support 20 on the fan motor 18 side through the rotation shaft. Therefore, the support 20 on the fan motor 18 side is in a state in which condensation water is hardly generated and has little effect even without forming the dew receiver 21.

In addition, the structure as shown in FIG. 5 may be sufficient. Here, the cross section of the dew receiver 21 is opened 25 so that the dew condensation accumulated in the hill 23 between the housing 22 and the side wall of the support 20 flows down from the opening 25. have.

The front drain plate 15 is disposed below the opening 25 and all condensation water flowing down from the opening is received by the front drain plate 15. The dew condensation water is not guided to at least the outlet 7, and thus it is the same as that described above to ensure comfortable air conditioning.

As described above, according to the air conditioner of the present invention, even when condensation water is generated and flows down to the support body supporting the blower, the air conditioner is prevented from scattering or falling out from the outlet to obtain optimal air conditioning, and compared with conventional condensation water measures. It has the effect of reducing process water, material cost, and cost.
