Description
Technical Field
The utility model relates to an indoor set of air conditioner that possesses up-down wind vane.
Background
An indoor unit of a conventional air conditioner has the following structure: an inlet port is formed on the upper surface side of the indoor unit main body, an outlet port is formed on the lower surface side, and a blower fan and a heat exchanger are arranged in an air passage connecting the inlet port and the outlet port. An up-down wind direction plate for adjusting the wind direction of the discharged wind in the up-down direction by changing the operation angle is disposed at the discharge port. The air sent from the blower fan and heat-exchanged by the heat exchanger is discharged into the room while the wind direction thereof is adjusted by the vertical wind direction plates.
In such an indoor unit of an air conditioner, the volume of the discharge air discharged from the discharge port is small at both left and right ends of the up-down wind direction plate. Therefore, when the discharge air is deflected upward by the up-down wind direction plate, the air flow along the lower surface of the up-down wind direction plate is weakened, and therefore, the indoor air is caught in the portion where the air flow is weakened from the side thereof. Therefore, during the cooling operation, dew condensation occurs on the lower surfaces of the left and right end portions of the up-down wind direction plate.
Therefore, there has been conventionally known a technique of providing wind direction guides for guiding the discharge wind to the outside at the left and right ends of the guide surface positioned on the upper surface when the up-down wind direction plate operates, and flowing the discharge wind further to the outside to suppress entrainment of the indoor air and prevent condensation during the cooling operation (for example, see patent document 1).
Patent document 1: japanese laid-open patent publication No. H06-288605
In patent document 1, the wind direction guide is provided on the vertical wind direction plate, so that dew condensation can be prevented. However, the dew condensation prevention is limited to a portion where the wind speed of the discharge wind is secured to a certain extent. There are the following problems: since the speed of the discharged air is reduced by the angle of operation of the vertical vanes, the structure of patent document 1 is less effective in suppressing entrainment of the indoor air.
In particular, when the user sets the up-down wind direction plate to an operation angle in the down-blowing direction (hereinafter, a down-blowing angle) during the cooling operation, the discharge wind is easily peeled off from the guide surface of the up-down wind direction plate. Therefore, the wind speed of the discharged wind on the guide surfaces of the up-down wind direction plates is significantly reduced. Further, since the air peeled off from the guide surface flows and is entrained in the indoor air, dew condensation on the guide surface of the up-down wind direction plate becomes more remarkable. That is, there is a problem that the effect of the wind direction guide is poor when the operation angle of the up-down wind direction plate is the down-blowing angle as described above.
SUMMERY OF THE UTILITY MODEL
The present invention has been made to solve the above problems, and an object of the present invention is to provide an indoor unit of an air conditioner capable of preventing dew condensation of vertical air vanes regardless of the operation angle of the vertical air vanes.
The utility model discloses an indoor set of air conditioner inhales indoor air from the sunction inlet, and after heat exchanger and refrigerant carried out the heat exchange, from the discharge port to indoor discharge, wherein, the indoor set of above-mentioned air conditioner possesses: an up-down wind direction plate which adjusts the wind direction of the discharged air discharged from the discharge port in the up-down direction; and an air direction guide provided on the up-down wind direction plate, the air direction guide causing the discharged air passing above the guide surface of the up-down wind direction plate to flow downward and to flow along the guide surface, the right side end portion or the left side end portion of the discharge port being closed, an upper region of the right side end portion or the left side end portion of the up-down wind direction plate being a non-discharge region in which the discharged air is not discharged from the discharge port, the air direction guide being disposed adjacent to the non-discharge region.
Further, the following configuration is possible: the wind direction guide includes a wind receiving plate disposed apart from the guide surface of the vertical wind direction plate, and the wind receiving plate is disposed at an angle such that an imaginary extension plane of the wind receiving plate intersects with the vertical wind direction plate.
Further, the following configuration is possible: the wind receiving plate of the wind direction guide is configured to: an upstream end of the air-receiving plate is located upstream of an upstream end of the vertical air-guiding plate, and a downstream end of the air-receiving plate faces the vertical air-guiding plate.
Further, the following configuration is possible: an independent air passage is formed between the air receiving plate and the vertical air vanes of the air guide, and the cross section of the air passage decreases from upstream to downstream.
[ Utility model effect ]
According to the present invention, the air flow guide provided in the guide surface of the vertical wind direction plate can be used to flow the air discharged from the end of the discharge port along the guide surface of the vertical wind direction plate, regardless of the angle of movement of the vertical wind direction plate. Therefore, the indoor air flowing backward toward the non-discharge region can be pressed out backward, and dew condensation on the up-down wind direction plates can be prevented.

Detailed Description
Hereinafter, a specific embodiment of an indoor unit of an air conditioner according to the present invention will be described in detail with reference to the drawings.
Fig. 1 is an external view of an indoor unit of an air conditioner according to embodiment 1 of the present invention. Fig. 2 is a diagram illustrating an internal configuration of an indoor unit of an air conditioner according to embodiment 1 of the present invention, the indoor unit being located at a center portion in the left-right direction.
As shown in fig. 1 and 2, an indoor unit (hereinafter referred to as "indoor unit") of an air conditioner includes an indoor unit main body 1 and a front panel 2 serving as a design member. An inlet port 1a for sucking air around the indoor unit into the indoor unit is formed in the upper surface of the indoor unit main body 1. Further, an outlet 1b for discharging air sucked into the indoor unit to the outside of the indoor unit is formed on the lower side of the indoor unit main body 1. The indoor unit main body 1 includes a front side discharge air passage surface 1c and a rear side discharge air passage surface 1d that form an indoor unit air passage extending from the inlet port 1a to the outlet port 1 b.
A heat exchanger 3 and a fan 4 are disposed in the indoor unit main body 1. The fan 4 takes in the indoor air 7 from the suction port 1a and passes it through the heat exchanger 3, thereby discharging the air-conditioning air from the discharge port 1b into the room. The fan 4 is a cross-flow fan, and is horizontally provided in the indoor unit main body 1 such that the axis of rotation of the cross-flow fan is in the left-right direction of the indoor unit main body 1. The heat exchanger 3 is disposed in the air flow generated by the fan 4, and generates air-conditioning air by performing heat exchange between the air sucked into the indoor unit through the suction port 1a and the refrigerant.
The outlet 1b of the indoor unit is provided with a vertical air vane 5, and the vertical air vane 5 adjusts the air direction of the discharge air discharged from the outlet 1b into the room in the vertical direction by changing the operation angle. The up-down wind direction plate 5 is rotatable in the up-down direction about a rotation shaft (not shown) extending in the left-right direction of the indoor unit. Specifically, a left and right driving motor (not shown) installed in the indoor unit main body 1 is connected to the rotation shaft of the up-down wind vane 5, and the up-down wind vane 5 is rotated in the up-down direction by the operation of the driving motor. This makes it possible to blow air-conditioning air generated inside the indoor unit freely in the vertical direction.
With the above configuration, the air-conditioning air generated inside the indoor unit is discharged from the outlet 1b to the outside of the indoor unit, and air conditioning can be performed freely in the room in which the indoor unit is installed.
Fig. 3 is an enlarged view of a portion surrounded by a broken line a in fig. 1.
An electrical component box (not shown) for housing electrical components is disposed on the right side in the indoor unit. A part of the electric component box faces the back side of the right end of the discharge port 1b, and closes the discharge port 1 b. Therefore, the outer appearance of the discharge port 1b is asymmetric in the left-right direction, and the right end of the discharge port 1b, in other words, the upper region of the right end of the up-down wind direction plate 5 becomes the non-discharge region 6 where no discharge is performed or the discharge amount is small even when the discharge is performed. Therefore, as shown in fig. 3, the indoor air 7 flows backward in the non-discharge area 6. Therefore, if nothing is done, during the cooling operation, the indoor air 7 containing moisture at a high temperature comes into contact with the up-down wind direction plates 5 cooled by the cold air from the discharge port 1b, and the indoor air 7 is cooled to the dew point temperature or lower, whereby dew condensation occurs on the upper surfaces of the up-down wind direction plates 5, that is, on the guide surfaces 5 a.
Therefore, in embodiment 1, in order to avoid such condensation early, the air direction guides 8 are provided on the guide surfaces 5a of the up-and-down wind direction plates 5. The wind direction guide 8 will be described below.
Fig. 4 is an enlarged view of a portion surrounded by a broken line B in fig. 3. Fig. 5 is a view corresponding to fig. 2 illustrating a portion surrounded by a broken line B in fig. 3. Fig. 6 is an enlarged view of a portion surrounded by a broken line C in fig. 5.
The air direction guide 8 causes the discharged air 9 passing above the guide surface 5a to flow downward and to flow along the guide surface 5a, and the air direction guide 8 is adjacent to the non-discharge region 6 and is formed integrally with the up-down wind direction plate 5 on the guide surface 5a of the up-down wind direction plate 5. The air guide 8 includes a pair of left and right ribs 8a standing from the guide surface 5a, and a wind receiving plate 8b connecting upper surfaces of the ribs 8a to each other, and an independent air passage 8c is formed between the air guide 8 and the guide surface 5 a. The flow passage cross section of the air passage 8c becomes smaller toward the downstream.
As shown in fig. 5 and 6, the wind receiving plate 8b faces the guide surface 5a at a position apart from the guide surface 5a, and the upstream end 8ba of the wind receiving plate 8b projects further upstream than the upstream end 5aa of the vertical wind direction plate 5, and the downstream end of the wind receiving plate 8b faces the vertical wind direction plate 5, and the wind receiving plate 8b is disposed so as to extend toward the downstream side by an angle at which the virtual extension surface 10 of the wind receiving plate 8b intersects with the vertical wind direction plate 5, and specifically, the wind receiving plate 8b is disposed on the rib 8a so that the virtual extension surface 10 intersects with the virtual line 11 connecting the vertical ends of the vertical wind direction plate 5 at an angle α.
Here, an example of the size of the wind receiving plate 8b is explained. The distances L1, L2, and L3 shown in fig. 6 are set in consideration of the case where the discharged air 9 flowing above the up-down wind deflector 5 is efficiently and sufficiently flowed to the up-down wind deflector 5. Here, the distance L1 is a distance in the direction of the normal line 21 perpendicular to the tangent 20 of the guide surface 5a at the upstream end 5aa, and is a distance between the upstream end 5aa of the up-down wind vane 5 and the wind guide 8. The distance L2 is a distance in the tangential line 20 direction, and is a distance at which the up-down wind direction plate 5 overlaps the wind direction guide 8. The distance L3 is a distance in the tangential line 20 direction, and is a distance by which the wind direction guide 8 projects further upstream than the upstream end 5aa of the vertical wind direction plate 5. The distances L1 and L2 were set to 5mm to 10mm, respectively.
The following describes the flow of air when the wind direction guide 8 is provided and when the wind direction guide 8 is not provided, and the dew condensation preventing effect by providing the wind direction guide 8.
Fig. 7 is a diagram for explaining the function of the airflow direction guide of the indoor unit according to embodiment 1 of the present invention, and is a diagram showing a state in which indoor air flows backward in the non-discharge region. Fig. 8 is a diagram for explaining the function of the airflow direction guide of the indoor unit of the air conditioner according to embodiment 1 of the present invention, and is a diagram showing a state in which the indoor air flowing backward is pushed out from the downstream area of the airflow direction guide by the exhaust air from the airflow direction guide.
When the wind direction guide 8 is not provided, the indoor air 7 flows backward in the non-discharge area 6. Here, when the operation angle of the up-down wind direction plate 5 is set to the downward blowing angle, the discharged air 9 does not flow along the guide surface 5a of the up-down wind direction plate 5, but is separated from the guide surface 5 a. That is, the discharged air 9 flows upward away from the guide surface 5a of the up-down wind direction plate 5. When the exhaust air 9 flows upward away from the guide surface 5a, the high-temperature indoor air 7 containing moisture comes into contact with the guide surface 5a located downstream of the exhaust air 9 and flows backward. The region of the guide surface 5a located downstream of the exhaust air 9, in other words, in the vicinity of the non-exhaust region 6, is cooled by the exhaust air 9. Therefore, the indoor air 7 comes into contact with the cooled area, and dew condensation occurs.
On the other hand, when the wind direction guide 8 is provided, as shown in fig. 5, the discharged air 9 flowing into the air passage 8c in the wind direction guide 8 collides with the rear surface of the wind receiving plate 8b, and is changed to a path in the direction toward the guide surface 5 a. Thereby, the discharged air 9 flows along the guide surface 5a toward the guide surface 5 a. Here, the windward plate 8b is configured such that: the upstream end 8ba protrudes further upstream than the upstream end 5aa of the vertical wind vane 5. Therefore, the discharged air 9 upstream of the up-down wind direction plate 5 is introduced into the air passage 8c in the wind direction guide 8, and more discharged air 9 flows along the guide surface 5 a.
In the non-discharge area 6, as shown in fig. 7, the room air 7 containing moisture and having a high temperature flows backward through the discharge port 1 b. However, as shown in fig. 8, the indoor air 7 is pushed out by the exhaust air 9 flowing along the guide surface 5 a. Here, since the flow path cross section of the air passage 8c becomes smaller toward the downstream, the discharged air 9 with an increased wind speed flows along the guide surface 5 a. This makes it possible to push out the room air 7 toward the non-discharge area 6 without flowing into the area downstream of the discharge air 9. Therefore, the conventional occurrence of condensation on the guide surface 5a in the vicinity of the non-discharge region 6 can be prevented.
The above-described wind receiving plate 8b functions even when the operation angle of the vertical wind direction plate 5 is at any angle within the operation range. Therefore, even in a situation where the operation angle of the up-down wind direction plate 5 is downward and the discharged air 9 is likely to be separated from the guide surface 5a of the up-down wind direction plate 5, the discharged air 9 can be made to flow along the guide surface 5a of the up-down wind direction plate 5 by the wind receiving plate 8 b. Therefore, dew condensation can be prevented from occurring on the guide surface 5a of the up-down wind direction plate 5. That is, even if the up-down wind direction plate 5 performs the cooling operation at any blow-down angle, the dew condensation can be prevented from occurring on the guide surface 5a of the up-down wind direction plate 5.
As described above, in the indoor unit according to embodiment 1, the air direction guide 8 is disposed adjacent to the non-discharge area 6, and the air direction guide 8 causes the discharged air to flow downward and to flow along the guide surface 5a of the up-down air flow direction plate 5. This allows the discharged air 9 flowing above the upstream end 5aa of the up-down wind direction plate 5 to continuously flow along the guide surface 5a, and allows the room air 7 containing moisture and having a high temperature flowing backward toward the non-discharge region 6 to be pushed out. This prevents the occurrence of reverse flow of air and condensation in the vicinity of the non-discharge region, which have conventionally occurred. Therefore, even if the cooling operation is performed at any blow-down angle by the up-down wind direction plate 5, the reverse flow of air and the condensation in the vicinity of the non-discharge area can be prevented. In this way, since the operation angle of the up-down wind direction plate 5 is not limited, the operation angle of the up-down wind direction plate 5 can be set to an arbitrary operation angle.
Further, since the wind receiving plate 8b of the wind direction guide 8 can be disposed at an angle such that the virtual extension surface 10 of the wind receiving plate 8b intersects with the vertical wind direction plate 5, the discharged air can be caused to flow downward and flow along the guide surface 5a of the vertical wind direction plate 5.
Further, since the upstream end portion 8ba of the airflow direction guide 8 is disposed so as to protrude further upstream than the upstream end portion 5aa of the up-down airflow direction plate 5, the discharged air 9 flowing above the upstream end portion 5aa of the up-down airflow direction plate 5 can be made to flow more along the guide surface 5a of the up-down airflow direction plate 5. Therefore, the occurrence of dew condensation can be more effectively prevented.
Further, since the airflow direction guide 8 is configured such that the flow path cross section of the airflow path 8c becomes smaller toward the downstream, the wind speed can be increased toward the downstream, and the effect of pushing out the indoor air 7 can be improved.
As a method for preventing condensation by suppressing the backflow of the indoor air 7, a method for increasing the wind speed of the discharged air 9 by narrowing the discharge port 1b is also considered. However, narrowing the discharge port 1b adversely affects static pressure recovery, resulting in deterioration of blower performance. On the other hand, in embodiment 1, the reverse flow of the indoor air 7 can be discharged without narrowing the discharge port 1 b. Therefore, in embodiment 1, as compared with the method of narrowing the discharge port 1b to increase the wind speed of the discharged air 9, the discharge port 1b can be enlarged to share the recovery of the static pressure, thereby improving the blower performance.
Further, according to embodiment 1, since dew condensation does not occur, the up-down wind direction plate 5 can be continuously operated while maintaining a state of being held at an arbitrary angle, and improvement of the down blowing performance and improvement of the comfort can be achieved.
In embodiment 1, the non-discharge region 6 is a right end portion, but may be a left end portion. In embodiment 1, the flow path cross section of the air passage 8c is configured to be smaller from upstream to downstream, but may be the same flow path cross section from upstream to downstream. At this time, the indoor air 7 is also sufficiently pushed out by the discharged air 9 from the air direction guide 8.
The indoor unit of the present invention is not limited to the structure shown in fig. 1, and various modifications can be made as follows without departing from the scope of the present invention.
Fig. 9 shows a modification of the airflow direction guide of the indoor unit according to embodiment 1 of the present invention. Fig. 10 is a diagram for explaining the function of the airflow direction guide of fig. 9, and is a diagram showing a state in which the indoor air is pushed back by the discharged air from the airflow direction guide.
The wind direction guide 8 described above includes a pair of ribs 8a on the left and right sides, but the ribs 8a may support the wind receiving plate 8b, and in this modification, there are 1 rib 8 d. A wind receiving plate 8b is provided on the upper surface of the rib 8d so that the rib 8d is positioned at the center. Even if the wind direction guide 8 is configured in this manner, the same effects as described above can be obtained.
