Description
Technical Field
The utility model relates to an indoor set and air conditioner. And more particularly to wind deflectors.
Background
Some conventional indoor units of air conditioners include an indoor unit in which a suction port is provided on an upper surface side of an indoor unit main body and an air outlet is provided on a lower surface side. Further, a blower fan and a heat exchanger are disposed in the indoor unit body and in a blower duct connecting the suction port and the discharge port. Further, a blow-out duct communicating with the blow-out port is formed on the downstream side of the blower fan. Further, an up-down wind direction plate that changes the direction of the airflow up and down is disposed near the air outlet. Further, electrical components are disposed on the left and right sides in the indoor unit main body.
Since the electrical components are disposed on the left and right sides in the indoor unit body, the blowing width is reduced. Therefore, the split blowing performance of the split blowing to the left and right is deteriorated. Further, since the air outlet is close to one side, the appearance of the indoor unit becomes asymmetric in the left-right direction. In order to alleviate these problems, a dummy duct portion is provided at an end portion of the air outlet so that the lateral width of the up-down wind direction plate is longer than the duct width of the air outlet.
However, the blown air is not blown out from the pseudo duct portion. Therefore, the wind speed is reduced at the pseudo wind path portion. Therefore, the indoor air having a high temperature containing moisture flows backward, and during the cooling operation, the indoor air contacts the up-down wind direction plates cooled by the blown air, and dew condensation occurs on the guide surfaces of the up-down wind direction plates. Therefore, by disposing the vertical wind direction plate in the upper wind path where the blowing wind speed is high, the reverse flow of the indoor air is suppressed, and the dew condensation is prevented.
Further, there has been proposed an indoor unit in which a blown air direction guide portion is provided on a guide surface of an upper and lower air direction plate, and the blown air direction is guided to the outer side to suppress entrainment of indoor air, thereby implementing a measure against dew condensation during a cooling operation (for example, see patent document 1).
Patent document 1: japanese laid-open patent publication No. H06-288605
However, the effect of providing the outlet wind direction guide is limited to a position where the outlet wind speed is secured to some extent. Therefore, there are the following problems: since the blowing wind speed is lowered by the height positions of the false duct portion and the vertical vanes, the effect of suppressing the entrainment of the indoor air is reduced.
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 and an air conditioner that prevent dew condensation of vertical air vanes.
In order to achieve the above object, the indoor unit of the present invention includes: a casing having a blow-out port at a lower portion thereof; an up-down wind direction plate provided at the air outlet and adjusting the direction of air blown out from the air passage in the casing; and a pseudo air duct portion having a pseudo air duct adjacent to the air duct and through which air in the casing does not pass, wherein the air outlet and the up-down wind direction plate are provided across the air duct and the pseudo air duct portion in a width direction of the casing, the up-down wind direction plate has a shielding plate at an end portion on a side where the pseudo air duct portion is provided, and a plate surface of the shielding plate is provided along a direction in which air is blown out from the air duct.
Preferably, the shield plate is provided such that, in the flow of the air blown out from the casing, the windward plate end is located on the windward side with respect to the center position of the rotation axis of the windward-up/down plate, and the shield plate is located on the pseudo wind path side with respect to the boundary between the wind path and the pseudo wind path.
Preferably, the casing has a plurality of vertical wind direction plates in a height direction thereof, and the plate surface of the shielding plate of the vertical wind direction plate located on a lower side is triangular.
Preferably, the indoor unit further includes: a cross flow fan disposed inside the case; and a heat exchanger that heats or cools the air flowing into the inside of the case.

In the following drawings, the same reference numerals are used for the same or corresponding components, and this is common throughout the embodiments described below. The embodiments of the constituent elements shown throughout the specification are merely examples, and are not limited to the embodiments described in the specification. In particular, the combination of the components is not limited to the combination in each embodiment, and the components described in other embodiments can be applied to another embodiment. In the following description, the upper side in the drawings is referred to as the "upper side" and the lower side is referred to as the "lower side". For easy understanding, terms indicating directions (for example, "right", "left", "front", "rear", and the like) are used as appropriate, but they are used for explanation and do not limit the invention of the present application. In addition, the vertical direction (height direction) is defined as the vertical direction when the indoor unit of the air conditioner is viewed from the front (front surface) side, and the horizontal direction (width direction) is defined as the horizontal direction. The pressure and temperature are not particularly determined in relation to absolute values, but rather are relatively determined in the state, operation, and the like of the device and the like. In the drawings, the relationship between the sizes of the respective components may be different from the actual one.
Fig. 1 is a diagram showing an external appearance of an indoor unit 100 of an air conditioner according to embodiment 1 of the present invention. Fig. 2 is a diagram illustrating a configuration related to the inside of the indoor unit 100 of the air conditioner according to embodiment 1 of the present invention. The indoor unit 100 of the air conditioner according to embodiment 1 is a wall-mounted indoor unit installed on a wall surface. But the type of the indoor unit 100 is not limited.
As shown in fig. 1 and 2, an indoor unit 100 of an air conditioner (hereinafter, referred to as "indoor unit 100") includes an indoor unit main body 1 and a front panel 2. The indoor unit main body 1 and the front panel 2 also serve as a casing of the indoor unit 100. The indoor unit main body 1 includes: a suction port 1a, a discharge port 1b, a front side air blowing duct surface 1c, and a rear side air blowing duct surface 1 d. The suction port 1a is an opening portion through which air around the indoor unit 100 flows into the indoor unit 100. The air outlet 1b is located at the lower portion of the indoor unit main body 1, and is an opening portion for blowing out the air flowing into the indoor unit 100 to the outside of the indoor unit 100. The front side air blowing duct surface 1c and the rear side air blowing duct surface 1d form walls constituting an air duct as a flow path of air passing from the suction port 1a to the air blowing port 1b in the casing of the indoor unit 100. In addition, the front panel 2 is a decorative member.
The indoor unit 100 includes an indoor heat exchanger 3 and a cross-flow fan 4 therein. The cross flow fan 4 is a cross flow blower. When the cross flow fan 4 is driven, air around the indoor unit 100 flows into the indoor unit 100 through the suction port 1a, passes through the indoor heat exchanger 3 and the cross flow fan 4, and flows out through the air passage and out through the discharge port 1 b. The indoor heat exchanger 3 performs air conditioning by performing heat exchange between air passing through the indoor heat exchanger 3 and a refrigerant flowing through a heat transfer pipe included in the indoor heat exchanger 3 to heat or cool the air. The indoor heat exchanger 3 is disposed so as to cover the cross flow fan 4 in an air passage on the intake side (front stage) upstream of the cross flow fan 4 in the flow of air. The air heat-exchanged by the indoor heat exchanger 3 is blown to the outside of the indoor unit 100, and air-conditioned space in which the indoor unit 100 is installed is conditioned.
The indoor unit 100 includes the horizontal air vanes 11 and the vertical air vanes 5 at the air outlet 1 b. The horizontal air vanes 11 adjust the direction of air blown out from the indoor unit 100 in the horizontal direction, which is the width direction of the indoor unit 100. The up-down airflow direction plate 5 adjusts the direction in which air is sent out from the indoor unit 100 in the vertical direction (up-down direction) that is the height direction of the indoor unit 100. In the indoor unit 100 according to embodiment 1, the up-down wind direction plate 5 includes two pieces (the first up-down wind direction plate 5a and the second up-down wind direction plate 5b) in the up-down direction. Each of the up-down wind direction plates 5 is rotatable in the up-down direction around a rotation axis. Actually, drive motors (not shown) attached to the left and right of the unit are connected to the rotation shafts of the first vertical wind direction plate 5a and the second vertical wind direction plate 5b, one by one. By operating the drive motor, the respective up-down wind direction plates 5 are rotatable in the up-down direction. This allows the air blown from the indoor unit 100 to be separately blown out in the vertical direction independently and freely.
An electrical component box (not shown) is also disposed inside the indoor unit 100. The electric component box houses electric components such as a control board that controls a drive motor that drives the cross flow fan 4, the vertical wind direction plate 5, and the like. In the indoor unit 100 of fig. 1, the electrical component box is disposed in the right internal space toward the indoor unit 100.
Fig. 3 is a diagram showing a configuration around the air outlet 1b on the side where the electric component box is arranged, of the air outlet 1b of the indoor unit 100 according to embodiment 1 of the present invention. Fig. 3 is an enlarged view of a portion a of fig. 1. The space in which the electric component box is disposed is separated from the air duct through which air passes inside the indoor unit 100, and thus air does not flow. Therefore, the width of the air duct is reduced with respect to the entire width of the indoor unit 100. The inner space in which the electrical component box is disposed is biased to either the left or the right of the indoor unit 100 (to the right of the indoor unit 100 in fig. 1 and the like). The split blowing performance toward the left-right split blowing is deteriorated. In particular, in the indoor unit 100 of fig. 1, the wind hardly flows to the right. In addition, the appearance of the outlet port 1b is made asymmetric.
Therefore, as shown in fig. 3, in the indoor unit 100 according to embodiment 1, the end portion of the outlet port 1b on the side where the electrical component box is disposed is the pseudo air duct portion 6. The pseudo air duct portion 6 has a pseudo air duct as a dummy member, which is provided adjacent to the air duct and is provided to widen the air outlet 1b so as to make the appearance look symmetrical in the left-right direction. The air outlet 1b and the vertical vanes 5 are provided across the duct and the pseudo duct portion 6. Therefore, the width of the air outlet 1b and each vertical air vane 5 is longer than the width of the air passage through which air passes by the size of the pseudo air passage portion 6.
Here, since the pseudo air duct is different from the air duct, air is not blown out from the pseudo air duct portion 6. Therefore, the indoor air 8 is swirled by the flow of the blown air and flows back by the vertical wind direction plates 5 around the pseudo duct portion 6 at the air outlet 1 b. Therefore, during the cooling operation, the indoor air 8 containing moisture at a high temperature comes into contact with the up-down wind direction plate 5 cooled by the cool air after air conditioning sent from the indoor unit 100, and when the indoor air 8 is cooled to the dew point temperature or lower, dew condensation occurs on the guide surface of the up-down wind direction plate 5.
Fig. 4 is a diagram illustrating the shielding plate 7 located at the second up-down wind direction plate 5b of the indoor unit 100 according to embodiment 1 of the present invention. Fig. 4 is a view from the side B shown in fig. 3. In the indoor unit 100 according to embodiment 1, the second vertical air-direction plate 5b provided in the air outlet 1b has the shielding plate 7 on the guide surface of the end portion on the side where the electrical component box is arranged. The shielding plate 7 is provided at a boundary portion between the air passage through which air flows and the pseudo air passage provided in the pseudo air passage portion 6. In the indoor unit 100 according to embodiment 1, the shutter 7 is formed integrally with the second up-down wind vane 5 b.
Fig. 5 is a diagram illustrating the flow of air around the air outlet 1b on the side where the electric component box is arranged in the air outlet 1b of the indoor unit 100 according to embodiment 1 of the present invention. Fig. 5 is a view from the side C shown in fig. 4. As shown in fig. 4 and 5, the shielding plate 7 is disposed on the guide surface side of the second up-down wind direction plate 5b such that a plate end portion 10 on the windward side in the flow of air from the wind path is located on the windward side of the rotational shaft center position 9 of the second up-down wind direction plate 5 b. The shield plate 7 is disposed so that the plate surface is parallel to the discharge direction 1e of the conditioned air discharged from the air duct in the indoor unit 100. The shield plate 7 is disposed at the second vertical wind direction plate 5b as described above, and thus the conditioned air sent out from the wind path is more effectively prevented from colliding with the indoor air 8.
As shown in fig. 5, the shielding plate 7 is disposed in the pseudo air path portion 6, and is not disposed in the air path of the air blown out from the air outlet 1 b. By disposing the shielding plate 7 in the pseudo air duct portion 6, it is possible to suppress the ventilation resistance, prevent the blowing pressure loss from being deteriorated, and prevent the occurrence of dew condensation due to the reverse flow of the indoor air 8 during the cooling operation. Here, the cross section of the shielding plate 7 is formed in a triangular shape. Therefore, even if the first vertical wind direction plate 5a rotates, the first vertical wind direction plate 5a does not collide with the shielding plate 7, and interference with the first vertical wind direction plate 5a can be prevented. Here, the shape of the shielding plate 7 is not limited to a triangle as long as the shielding plate 7 does not contact the first vertical wind direction plate 5 a. Here, the case where only the second vertical wind direction plate 5b has the shielding plate 7 is described, but the present invention is not limited to this. The first up-down wind deflector 5a may have a shielding plate 7.
As described above, in the indoor unit 100 according to embodiment 1, the shielding plate 7 is provided on the guide surface side of the second vertical wind vane 5b and at the end portion on the side where the pseudo air path portion 6 having a low wind speed is provided. Therefore, the reverse flow of the indoor air 8 can be blocked, and the second vertical wind direction plates 5b can be prevented from condensation. In addition, the up-down wind direction plate 5 can be disposed in a position where the outlet wind speed is low in the indoor unit 100. Further, the expansion of the outlet port 1b can be allocated to the static pressure recovery, thereby achieving the improvement of the blower performance.
Fig. 6 is a diagram showing an example of the configuration of an air conditioner according to embodiment 2 of the present invention. Here, fig. 6 shows an air conditioner as an example of a refrigeration cycle apparatus. In fig. 6, the same operation is performed for the portions described in fig. 1 and the like. In the air conditioner of fig. 6, an outdoor unit (outdoor unit) 200 and the indoor unit (indoor unit) 100 described in embodiment 1 are connected by pipes via a gas refrigerant pipe 300 and a liquid refrigerant pipe 400 to form a refrigerant circuit for circulating a refrigerant. The outdoor unit 200 includes a compressor 210, a four-way valve 220, an outdoor heat exchanger 230, and an expansion valve 240.
The compressor 210 compresses and discharges a sucked refrigerant. Here, although not particularly limited, the compressor 210 may be a compressor that changes the capacity (the amount of refrigerant sent per unit time) of the compressor 210 by arbitrarily changing the operating frequency via an inverter circuit or the like, for example. The four-way valve 220 is a valve that switches the flow of the refrigerant between cooling operation and heating operation, for example.
The outdoor heat exchanger 230 of the present embodiment performs heat exchange between the refrigerant and air (outdoor air). For example, the refrigerant functions as an evaporator during heating operation, and evaporates and gasifies the refrigerant. Further, the refrigerant functions as a condenser during the cooling operation, and condenses and liquefies the refrigerant.
An expansion valve 240 such as an expansion device (flow rate control means) decompresses and expands the refrigerant. For example, in the case of an electronic expansion valve or the like, the opening degree is adjusted based on an instruction from a control device (not shown) or the like.
The indoor heat exchanger 3 described in embodiment 1 performs heat exchange between air to be air-conditioned and a refrigerant, for example. In the heating operation, the refrigerant functions as a condenser and is condensed and liquefied. Further, the refrigerant functions as an evaporator during the cooling operation, and evaporates and gasifies the refrigerant. The cross-flow fan 4 passes air through the indoor unit 100 as described above to air-condition the air, and sends the air to the air-conditioned space.
By configuring the air conditioner as described above, the flow of the refrigerant is switched by the four-way valve 220 of the outdoor unit 200, and the heating operation and the cooling operation can be realized. In the air conditioner according to embodiment 2, the provision of the shielding plate 7 prevents the cool air blown out from the indoor unit 100 from coming into contact with the warm air in the room during the cooling operation, thereby preventing condensation.
Although the air conditioner has been described in embodiment 2 above, the present invention can be applied to other refrigeration cycle apparatuses, such as indoor units of a refrigeration apparatus and a refrigeration apparatus.
