Description
Technical Field
The present invention relates to a structure of a heat exchanger of an indoor unit of an air conditioner.
Background
The structure of a conventional heat exchanger disposed in an indoor unit of an air conditioner will be described below with reference to fig. 3 and 4.
As shown in fig. 3 and 4, the indoor unit 10 is a horizontally long casing and is installed on an indoor wall 11. A front suction port 12 having a front suction grill 12a is provided on a front surface of the casing 10, and a lower suction port 13 having a lower suction grill 13a is provided on a lower surface of the casing 10. A front portion of the lower surface of the casing 10 is provided with a blow-out port 14 having an opening formed toward the lower front side of the casing 10 between the front intake port 12 and the lower intake port 13.
A cross flow fan 15 having a rotation axis in the horizontal direction is provided substantially at the center in the casing 10. The air flow path 18 (also referred to as a diffuser) descends toward the front of the casing 10, and guides the air generated by the rotation of the cross flow fan 15 to the air outlet 14. The air blowing path 18 includes a stabilizer 16 and a rear guide 17. The stabilizer 16 has a peak 16a that is closely opposed to the cross flow fan 15 and is located on the downstream side of the cross flow fan 15.
The 1 st heat exchanger 19 and the 2 nd heat exchanger 20 are located before and after the cross flow fan 15 on the windward side of the cross flow fan 15, and are provided in the casing 10 so as to sandwich the cross flow fan 15. The 1 st heat exchanger 19 includes an upper 1 st heat exchanger 19a and a lower 1 st heat exchanger 19b, and the 2 nd heat exchanger 20 includes an upper 2 nd heat exchanger 20a and a lower 2 nd heat exchanger 20 b.
The 1 st heat exchanger 19 is disposed such that the upper 1 st heat exchanger 19a is inclined toward the cross flow fan 15 and the lower 1 st heat exchanger 19b is vertical, and is substantially shaped in the reverse く. The 2 nd heat exchanger 20 is disposed in a substantially く shape such that the upper 2 nd heat exchanger 20a is vertical and the lower 2 nd heat exchanger 20b is inclined toward the rear side in the casing 10.
The water receiving tray 21 receives the dew condensation water from the 1 st heat exchanger 19 and the 2 nd heat exchanger 20. A heat insulating member 22 is provided on the back surface of the drain pan 21. The air flowing into the heat exchangers 19 and 20 is purified by the filter 23.
The filter 23 is provided so as to cover the front suction port 12 and the lower suction port 13. The water introduction pipe 24 receives the dew condensation water from the 2 nd heat exchanger 20.
When the cross-flow fan 15 is rotated in the arrow direction shown in fig. 4, air flowing in from the front suction grill 12a of the casing 10 (indicated by an arrow) is sucked into the 1 st heat exchanger 19 from the front suction inlet 12, and air flowing in from the lower suction grill 13a of the casing 10 (indicated by an arrow) is sucked into the 2 nd heat exchanger 20 from the lower suction inlet 13. The air heat-exchanged by the 1 st heat exchanger 19 or the 2 nd heat exchanger 20 is blown out obliquely downward (in the direction of the arrow) from the blowout port portion 14 through the air flow path 18 by the cross flow fan 15. At this time, the dew condensation water generated in the 1 st heat exchanger 19 and the 2 nd heat exchanger 20 flows down to the respective drain pans 21 (see, for example, patent document 1).

Detailed Description
The present invention 1 is an indoor unit of an air conditioner, comprising: a suction inlet; a fan for sucking air from the suction inlet; a heat exchanger disposed outside the fan and exchanging heat with the air sucked from the suction port; a ventilation path through which the air sucked by the fan flows; an outlet port through which the air heat-exchanged by the heat exchanger is blown; and a rear guide forming a rear surface side of the ventilation path, the heat exchanger including: a front surface side heat exchange unit disposed outside a front surface side of the fan; and a rear-side heat exchange portion disposed outside the rear side of the fan, wherein an upstream-side upper end portion of the rear guide is located between the fan and the rear-side heat exchange portion, and a shape changing portion is provided on a downstream surface of the rear-side heat exchange portion facing the rear guide, the shape changing portion being located on a rear side of the upstream-side upper end portion of the rear guide, and the downstream surface located below the shape changing portion being formed into a curved surface shape that is curved or bent in a direction toward the fan.
This makes it possible to reduce the lateral width of the body of the indoor unit on which the heat exchanger is mounted, and to provide an indoor unit of an air conditioner that is excellent in installation and appearance. Further, since the space between the rear surface side of the rear guide having the substantially circular arc shape and the rear surface side heat exchange portion is gradually enlarged toward the upstream upper end portion of the rear guide, a smooth flow space is formed, the air blowing performance is improved, and the indoor unit of the air conditioner which can save energy and reduce noise can be provided.

This allows the air sucked from the suction port to flow into the heat exchanger substantially uniformly, thereby improving the heat exchanger efficiency of the heat exchanger sucking the air from the suction port.
Further, since the air sucked through the suction port flows into the fan substantially uniformly, when the air volume of the air blown out from the air outlet is Q and the input to the motor for driving the fan is W, Q/W, that is, the fan efficiency is improved, and therefore, energy saving of the indoor unit can also be achieved.
The 4 th invention, particularly in any one of the inventions from 1 st to 3 rd, is characterized in that: another heat exchanger is disposed on the upstream surface of the rear-side heat exchange portion.
This makes it possible to achieve high performance in air conditioning operation of the indoor unit such as heating operation, cooling operation, and dehumidifying operation.
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Further, the present invention is not limited to this embodiment.
(embodiment mode 1)
Fig. 1 is a vertical sectional view of an indoor unit of an air conditioner according to embodiment 1 of the present invention during a shutdown. Fig. 2 is a vertical sectional view of an indoor unit of an air conditioner according to embodiment 1 of the present invention during operation.
An air conditioner according to embodiment 1 of the present invention includes an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected by a refrigerant pipe and a control wiring, and constitute a heat pump. The outdoor unit is provided with a compressor. The indoor unit is mounted on an indoor wall surface.
The following describes a configuration of an indoor unit of an air conditioner according to embodiment 1 of the present invention, with reference to fig. 1 and 2.
An indoor unit of an air conditioner according to embodiment 1 of the present invention includes a main body 1 including an inlet 2 and an outlet 3.
The suction port 2 is formed on the upper surface of the main body 1, and the discharge port 3 is formed on the lower surface of the main body 1. The rear surface of the body 1 is mounted to a wall surface.
Inside the main body 1, a fan 6 that sucks air from the suction port 2 and a heat exchanger 5 that exchanges heat with the air sucked from the suction port 2 are provided.
The heat exchanger 5 includes a front-side heat exchange portion 5a disposed outward of the front side of the fan 6 and a back-side heat exchange portion 5b disposed outward of the back side of the fan 6, and the front-side heat exchange portion 5a and the back-side heat exchange portion 5b are continuous in the top surface portion. Further, a front surface side sub heat exchange portion 5c is provided on the upstream surface 5ay of the front surface side heat exchange portion 5 a. A back-side sub heat exchange portion 5d is provided on the upstream surface 5by of the back-side heat exchange portion 5 b.
The fan 6 is preferably a cross-flow fan (cross-flow fan). Any rotating shaft at the left and right ends of the fan 6 is connected to a motor (not shown). Further, a filter 4 is disposed between the suction port 2 and the fan 6 or between the suction port 2 and the heat exchanger 5.
The ventilation path 7, which is arranged downstream of the fan 6 and guides the flow of air, from downstream of the fan 6 to upstream of the air outlet 3, includes: a rear guide 7a having a substantially circular arc shape forming a rear surface side of the ventilation path 7; a stabilizer 7b disposed opposite to the rear guide 7 a; and both side walls (not shown) of the main body 1. Further, the upstream upper end portion 7w of the rear guide 7a is located between the fan 6 and the back-side heat exchange portion 5b, and a part of the rear guide 7a is located between the fan 6 and the back-side heat exchange portion 5 b.
The air outlet 3 is provided with vertical airflow direction changing blades 8 and horizontal airflow direction changing blades 9. The horizontal airflow direction changing blades 9 are disposed upstream of the vertical airflow direction changing blades 8. The vertical airflow direction changing blade 8 opens and closes the air outlet 3 to change the air blowing in the vertical direction. The left-right airflow direction changing blade 9 changes the blowing of air in the left-right direction.
That is, during air conditioning operation of the indoor unit such as heating operation, cooling operation, and dehumidifying operation of the air conditioner, the fan 6 is driven to exchange heat between the air sucked from the suction port 2 and the refrigerant flowing through the heat exchanger 5. During the air conditioning operation of the indoor unit, the indoor unit is rotated from the state in which the vertical airflow direction changing blade 8 shown in fig. 1 covers the outlet port 3 to the state in which the outlet port 3 is opened as shown in fig. 2, and air having exchanged heat with the refrigerant flowing through the heat exchanger 5 is blown out from the outlet port 3.
In the indoor unit of an air conditioner according to embodiment 1 of the present invention, at least the downstream surface 5bx of the back-side heat exchange portion 5b facing the rear guide 7a has a shape changing portion 5w, and the shape changing portion 5w is located on the back surface side of the upstream upper end portion 7w of the rear guide 7 a. The back-side heat exchange portion 5b is formed in a curved surface shape in which a downstream surface 5bx located below the shape changing portion 5w is curved or bent in a direction toward the fan 6. The upstream surface 5by facing the downstream surface 5bx is formed in a curved surface shape curved or bent in a direction approaching the fan 6.
In the back-side heat exchange portion 5b, at least a portion 5bz located on the most back surface side is formed thinner than a portion located above the shape changing portion 5 w.
That is, as shown in fig. 2, the rear-side heat exchange portion 5b is formed with a predetermined thickness Th above the shape changing portion 5w, a thickness Tm lower than the predetermined thickness Th below the shape changing portion 5w, and a thickness Tl lower than the thickness Tm at the lowermost portion 5 bz. In this way, the thickness of the portion of the back-side heat exchange portion 5b from the shape changing portion 5w to the lower portion side is gradually reduced. That is, when the thickness of the rear-side heat exchange portion 5b on the upper side of the shape changing portion 5w is represented by Th, the thickness of the portion of the rear-side heat exchange portion 5b on the lower side of the shape changing portion 5w and on the side closest to the backrest surface is represented by Tm, and the thickness of the rear-side heat exchange portion 5b on the lower side of the shape changing portion 5w and on the lowermost end is represented by Tl, Tl < Tm < Th is present.
This makes it possible to reduce the lateral width B of the back-side heat exchange unit 5B and the body 1 of the indoor unit on which it is mounted, and to provide an indoor unit of an air conditioner that is excellent in installation and appearance.
Further, the space between the rear surface side of the rear guide 7a having the substantially circular arc shape and the rear surface side heat exchange portion 5b gradually expands toward the upstream upper end portion 7w of the rear guide 7a, thereby forming a smooth flow space and improving the air blowing performance, and an indoor unit of an air conditioner which can save energy and reduce noise can be provided.
In addition, since the air flow can be facilitated by reducing the ventilation resistance at the portion where the thickness of the back-side heat exchange portion 5b is made thin, the heat exchange capability of the back-side heat exchange portion 5b can be improved.
As shown in fig. 1 and 2, the front-side heat exchange portion 5a and the back-side heat exchange portion 5b are separate members, and the front-side heat exchange portion 5a and the back-side heat exchange portion 5b are joined to each other at the top surface portion. As a result, the front-side heat exchange portion 5a and the back-side heat exchange portion 5b are formed in a continuous shape in the top surface portion.
This allows the air sucked from the suction port 2 to flow into the heat exchanger 5 substantially uniformly, thereby improving the heat exchanger efficiency of the heat exchanger 5 of the air sucked from the suction port 2.
Since the air sucked through inlet 2 flows into fan 6 substantially uniformly, if the volume of air blown out from outlet 3 is Q and the input to a motor (not shown) that drives fan 6 is W, Q/W, i.e., fan efficiency, is improved, and therefore energy saving of the indoor unit can also be achieved.
As shown in fig. 1 and 2, a front-side sub heat exchange portion 5c and a back-side sub heat exchange portion 5d, which are other heat exchangers, are disposed on the upstream surface 5ay of the front-side heat exchange portion 5a and the upstream surface 5by of the back-side heat exchange portion 5b, respectively.
This makes it possible to achieve high performance in air conditioning operation of the indoor unit such as heating operation, cooling operation, and dehumidifying operation.
