The present disclosure relates to an indoor unit for an air conditioner.
To avoid wind of an indoor unit for an air conditioner from hitting a person and generating a draft feeling, PTL 1 suggests using a circulation airflow and a perpendicular airflow as airflows for uniform air conditioning of the entirety of a room without causing a person to feel wind.
A first aspect of the present disclosure is an indoor unit for an air conditioner, the indoor unit being configured to be installed in an air-conditioning target space and to be capable of changing a direction of an airflow that is blown out through a blow-out port (15). The indoor unit includes a control unit (40) configured to switch between a normal mode and a wide mode. The control unit (40) is configured to switch to the wide mode when an air conditioning load is higher than a predetermined value and extend at least vertically a range that is to be reached by the airflow in the air-conditioning target space in the wide mode compared with the normal mode. In the wide mode, when a range of 1600 mm high from a floor surface at a position away from the blow-out port (15) by any distance within a range of 1000 mm to 2000 mm on a front side is set as a reference height range, and among three ranges obtained by equally dividing the reference height range into three in a height direction, the range positioned on an upper side is set as a first range, the range positioned on a lower side is set as a second range, and the range positioned in a middle is set as a third range, and when the indoor unit for an air conditioner is provided on a side wall in the air-conditioning target space such that a center of the blow-out port (15) is at a position of 2000 mm above from the floor surface, an average wind velocity in the first range and an average wind velocity in the second range are substantially equal to each other, and an average wind velocity in the third range is equal to or more than 0.5 times and less than 1.1 times of the average wind velocity in the first range.
Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The following embodiment is presented as a substantially preferable example and does not intend to limit the present invention, applications thereof, or the range of the use thereof.
The air-conditioner indoor unit (10) is of a wall-mount type to be installed on a side wall in an air-conditioning target space. The air-conditioner indoor unit (10) mainly includes a body casing (11), a heat exchanger (13), a fan (14), a bottom frame (16), and a control unit (40). The air-conditioner indoor unit (10) is configured to be capable of changing the direction of an airflow that is blown out through a blow-out port (15).
The body casing (11) has a top surface portion (11a), a front surface panel (11b), a back surface plate (11c), and a bottom surface plate (11d). In the inside of the body casing (11), the heat exchanger (13), the fan (14), the bottom frame (16), the control unit (40), and the like are housed.
The top surface portion (11a) is positioned at an upper portion of the body casing (11). An intake port (not illustrated) is provided at a front portion of the top surface portion (11a).
The front surface panel (11b) constitutes the front surface part of the air-conditioner indoor unit (10) and has a flat shape with no intake port. The upper end of the front surface panel (11b) is rotatably supported by the top surface portion (11a). Consequently, the front surface panel (11b) is movable in a hinge manner.
The heat exchanger (13) and the fan (14) are mounted on the bottom frame (16). The heat exchanger (13) exchanges heat with passing air to thereby regulate the temperature of the air. The heat exchanger (13) has an inverted V-shape in which both ends are bent downward in a side view. The fan (14) is positioned below the heat exchanger (13). The fan (14) is, for example, a cross-flow fan and causes air that is taken in from the inside of a room to pass through the heat exchanger (13) and to be blown out into the inside of the room.
The bottom surface plate (11d) is provided with the blow-out port (15). The blow-out port (15) is a rectangular opening having long sides in the lateral direction (direction orthogonal to the sheet of
A first wind-direction regulating plate (31) that changes the direction of an airflow (hereinafter may be referred to as blow-out air) blown out through the blow-out port (15) is rotatably mounted along the long side of the blow-out port (15) on the side of the back surface plate (11c). The first wind-direction regulating plate (31) may be constituted by one plate that has a length substantially the same as the length of the blow-out port (15) and that is not divided. The first wind-direction regulating plate (31) is driven by a motor (not illustrated) and is capable of not only changing the direction of blow-out air but also opening and closing the blow-out port (15). The first wind-direction regulating plate (31) can take a plurality of orientations having different inclination angles.
A second wind-direction regulating plate (32) is provided along the long side of the blow-out port (15) on the side of the front surface panel (11b). The second wind-direction regulating plate (32) may be constituted by one plate that has a length substantially the same as the length of the blow-out port (15) and that is not divided. The second wind-direction regulating plate (32) can be caused by a motor (not illustrated) to take a plurality of orientations having different inclination angles in the front-rear direction. During operation stop, the second wind-direction regulating plate (32) is housed in a housing portion (130) provided at the bottom surface plate (11d).
The blow-out port (15) is connected to the inside of the body casing (11) by a blow-out flow path (18). The blow-out flow path (18) is formed along a back-surface-side scroll (17) of the bottom frame (16) from the blow-out port (15). The back-surface-side scroll (17) is a partition wall that constitutes a portion of the bottom frame (16) and is curved to face the fan (14). A terminal end (F) of the back-surface-side scroll (17) is positioned in the vicinity of the peripheral edge of the blow-out port (15). The body casing (11) is provided with a front-surface-side scroll (19) that faces the back-surface-side scroll (17) with the blow-out flow path (18) therebetween.
When the fan (14) is operated, indoor air is taken in through the intake port of the top surface portion (11a) by the fan (14) via the heat exchanger (13) and is blown out from the fan (14) through the blow-out port (15) via the blow-out flow path (18). The air that passes through the blow-out flow path (18) moves forward along the back-surface-side scroll (17) and is sent in the tangential direction of the terminal end (F) of the back-surface-side scroll (17).
The control unit (40) is positioned on the side of the heat exchanger (13) and the fan (14) when, for example, the body casing (11) is viewed from the front of the front surface panel (11b). The control unit (40) performs switching of blow-out modes, which will be described later, control of the number of rotations of the fan (14), control of the operation of the first wind-direction regulating plate (31) and the second wind-direction regulating plate (32), control of the temperature of the heat exchanger (13), and the like.
Although not illustrated, a perpendicular wind-direction regulating plate may be provided at a portion in the blow-out flow path (18) closer to the fan (14) than the first wind-direction regulating plate (31). The perpendicular wind-direction regulating plate has a plurality of blade pieces and a coupling rod that couples the plurality of blade pieces. By the motor (not illustrated) causing the coupling rod to reciprocate horizontally in the longitudinal direction of the blow-out port (15), the plurality of blade pieces swing leftward and rightward with respect to a state perpendicular to the longitudinal direction.
An outer surface (31a) of the first wind-direction regulating plate (31) is completed to be on the extension of the outer surface of the bottom surface plate (11d) in a state in which the first wind-direction regulating plate (31) closes the blow-out port (15). An inner surface (31b) (refer to
A rotary shaft (311) of the first wind-direction regulating plate (31) is provided at the peripheral edge of the blow-out port (15) on the side of the back surface plate (11c) (at a position below the back-surface-side scroll (17)). The base portion of the first wind-direction regulating plate (31) and the rotary shaft (311) are coupled together with a predetermined interval kept therebetween. The rotary shaft (311) is coupled to a rotary shaft of a motor (not illustrated) fixed to the body casing (11).
By the rotary shaft (311) rotating counterclockwise in the front view in
In a state in which the first wind-direction regulating plate (31) opens the blow-out port (15), the blow-out air blown out through the blow-out port (15) flows substantially along the inner surface (31b) of the first wind-direction regulating plate (31). In other words, the direction of an airflow that is blown out substantially in the tangential direction of the terminal end (F) of the back-surface-side scroll (17) is changed by the first wind-direction regulating plate (31).
An outer surface (32a) of the second wind-direction regulating plate (32) is completed to be on the extension of the outer surface of the bottom surface plate (11d) in a state in which the second wind-direction regulating plate (32) is housed in the housing portion (130). An inner surface (32b) of the second wind-direction regulating plate (32) is completed to be along the surface of the housing portion (130).
A rotary shaft (321) of the second wind-direction regulating plate (32) is provided at the peripheral edge of the blow-out port (15) on the side of the front surface panel (11b) (in the vicinity of the terminal end of the front-surface-side scroll (19)). In other words, the second wind-direction regulating plate (32) is provided to be continuous with the front-surface-side scroll (19). The base portion of the second wind-direction regulating plate (32) and the rotary shaft (321) are coupled together. The rotary shaft (321) is coupled to a rotary shaft of a motor (not illustrated) fixed to the body casing (11).
By the rotary shaft (321) rotating counterclockwise in the front view in
In any of cooling operation, heating operation, dehumidifying operation, humidifying operation, and air-blowing operation, the air-conditioner indoor unit (10) can switch the blow-out modes among, for example, an “upward blowing mode”, an “oblique blowing mode”, a “wide mode”, and a “downward blowing mode” by controlling the first wind-direction regulating plate (31), the second wind-direction regulating plate (32), and the like.
In the following description, the “upward blowing mode”, the “oblique blowing mode”, and the “downward blowing mode” may be collectively referred to as the “normal mode”. Types of the blow-out modes and blow-out directions can be selected by a user via a remote controller or the like or can be set by the control unit (40) automatically.
In the “upward blowing mode”, as illustrated in
In the “oblique blowing mode”, as illustrated in FIG. 3, the control unit (40) rotates the first wind-direction regulating plate (31) to a position at which the inner surface (31b) of the first wind-direction regulating plate (31) is directed substantially in the tangential direction of the terminal end (F) of the back-surface-side scroll (17) and rotates the second wind-direction regulating plate (32) to a position at which the outer surface (32a) of the second wind-direction regulating plate (32) is directed substantially in the horizontal direction. Consequently, the airflow that is blown out through the blow-out port (15) moves forward obliquely downward as it is by passing between the first wind-direction regulating plate (31) and the second wind-direction regulating plate (32). In the “oblique blowing mode”, the volume of the blow-out air can be maximum.
In the “wide mode”, as illustrated in
To cause an airflow not to easily separate from the back-surface-side scroll (17) and the front-surface-side scroll (19) when the airflow is blown out through the blow-out port (15), the first wind-direction regulating plate (31) and the second wind-direction regulating plate (32) may be provided such that the airflow can pass also along the outer surface (31a) of the first wind-direction regulating plate (31) and the inner surface (32b) of the second wind-direction regulating plate (32).
In the “downward blowing mode”, as illustrated in
As illustrated in
In contrast, it is possible in the “wide mode” to cause the blow-out air to hit the whole body of the person since the range that is to be reached by the blow-out air is extended vertically compared with the “normal mode”.
In the “wide mode”, the following state of the blow-out air is achieved by the control unit (40). This is on the premise that the width (short-side length) of the blow-out port (15) is 300 mm or less.
When (1) a range of 1600 mm high from a floor surface at a position away from the blow-out port (15) by any distance within a range of 1000 mm to 2000 mm on the front side is set as a reference height range,
(2) among three ranges obtained by equally dividing the reference height range into three in the height direction, the range positioned on the upper side is set as a first range, the range positioned on the lower side is set as a second range, and the range positioned in the middle is set as a third range, and
(3) the air-conditioner indoor unit (10) is provided on a side wall in the air-conditioning target space such that the center of the blow-out port (15) is at a position of 2000 mm above from the floor surface,
(4) an average wind velocity in the first range and an average wind velocity in the second range are substantially equal to each other, and an average wind velocity in the third range is less than 1.5 times of the average wind velocity in the first range.
The state of the blow-out air in the “wide mode” is achieved in a range of at least 1000 mm or more in a direction parallel to the long sides of the blow-out port (15). In the “wide mode”, the average wind velocity in the third range is preferably equal to or more than 0.5 times and less than 1.1 times of the average wind velocity in the first range. In the “wide mode”, an average wind velocity in the reference height range may be 0.5 m/s or more. In the “wide mode”, the width of the blow-out port (15) may be 150 mm or less. In the “wide mode”, a percentage of a turbulent flow region occupying the entirety of the blow-out air that is immediately after (in other words, in the vicinity of the blow-out port (15)) being blown out through the blow-out port (15) is preferably less than 30%.
In the wind velocity distribution in
In the wind velocity distribution in
Comparing the “wide mode” with the “normal mode” when the capacity (air conditioning capacity) of the air-conditioner indoor unit (10) and the wind velocity (average wind velocity) of the blow-out air are the same therebetween, the area of the airflow (a range in which the blow-out air passes through in the height direction) is larger in the “wide mode”, as illustrated in
In the present embodiment, when a difference between a set temperature of the air-conditioner indoor unit (10) and an intake temperature is large (for example, 3° C. or more) as with, for example, when the operation of the air-conditioner indoor unit (10) is started, when a set temperature is changed, or the like, in other words, when an air conditioning load is higher than a predetermined value, the control unit (40) switches to the “wide mode”, which is efficient in terms of air conditioning capacity. Consequently, it is possible to perform comfortable air conditioning while suppressing an increase in the air conditioning capacity even when the air conditioning load is high.
When switching to the “wide mode”, the control unit (40) may increase the number of rotations of the fan (14) to suppress a decrease in the wind velocity of the blow-out air. In addition, to reduce a difference between an intake temperature and a blow-out temperature compared with the “normal mode” or to cause the difference between the intake temperature and the blow-out temperature to be a predetermined value or less when switching to the “wide mode”, the control unit (40) may control the air conditioning capacity, for example, regulate the number of rotations of a compressor of an outdoor unit (not illustrated) or the opening degree of an electric valve.
In the “wide mode”, since the Coanda effect is used to extend the area of the airflow, separation of the airflow easily occurs on the inner surface (31b) of the first wind-direction regulating plate (31) and on the outer surface (32a) of the second wind-direction regulating plate (32). Therefore, condensation easily occurs during cooling as a result of contact between cool wind and room temperature air on the inner surface (31b) of the first wind-direction regulating plate (31) and on the outer surface (32a) of the second wind-direction regulating plate (32).
Thus, in the present embodiment, the control unit (40) may switch to the “normal mode” when the “wide mode” has been continued for a predetermined period or more during cooling. In this case, the air conditioning capacity of the “normal mode” may be increased to an air conditioning capacity at the time before switching to the “wide mode”.
The “normal mode”, in particular, the “upward blowing mode” and the “downward blowing mode” are suitable for heating and cooling the entirety of a room by a circulation airflow that circulates in the entirety of the inside of the room.
Thus, in the present embodiment, the air-conditioner indoor unit (10), a remote controller, or the like may be provided with a person detector, for example, a room occupancy sensor, and the control unit (40) may switch between the “normal mode” and the “wide mode” on the basis of presence/absence of a person inside and outside a range that is to be reached by the blow-out air of the “wide mode” in the air-conditioning target space. For example, when the number of persons in a room is two or more, the mode may be switched from the “wide mode” to the “normal mode”. The mode may be switched to the “wide mode” when persons are present only in the “aforementioned range”, and the mode may be switched to the “normal mode” when persons are present in both of the “aforementioned range” and the “other ranges”. When the number of persons in a room has decreased, the mode may be switched from the “normal mode” to the “wide mode”.
In the present embodiment, the control unit (40) may cause the temperature of at least a portion of the heat exchanger (13) to be lower than a dew temperature in the air-conditioning target space in the “wide mode” during cooling.
In the present embodiment, the control unit (40) may vary in the “wide mode” the blow-out velocity of the airflow as in, for example, the 1/f fluctuation and a wind-velocity jump. Specifically, the blow-out velocity of the airflow may be varied in a range of, for example, 0 to 0.5 m/s by changing the number of rotations of the fan (14), the angles of the first wind-direction regulating plate (31) and the second wind-direction regulating plate (32), the angles of the back-surface-side scroll (17) and the front-surface-side scroll (19), and the like.
According to the air-conditioner indoor unit (10) of the present embodiment described above, the range that is to be reached by the airflow blown out through the blow-out port (15) is extended in the “wide mode” to be larger than in the “normal mode”, and thus, it is possible to achieve a predetermined indoor temperature (set temperature) by causing a blow-out temperature to be closer to an intake temperature than in the “normal mode” when compared on the basis of the same air conditioning capacity and the same blow-out velocity. Accordingly, when the air conditioning load is increased as with when operation is started, when the set temperature is changed, or the like, it is possible to immediately heat and cool the body of a user with a spread airflow while suppressing a draft feeling by switching to the “wide mode”.
The airflow of the “wide mode” is an airflow that blows across not only a portion of the body of a user but also the whole body and thus improves the comfortable feeling of the user. By the airflow of the “wide mode” hitting the whole body of the user, a variation in the temperature distribution on the body of the user is reduced. The load on the body of the user is thus reduced.
In the “wide mode”, the range that is to be reached by the airflow is extended to be larger than in the “normal mode” and thus is less likely to be limited by layout, furniture arrangement, the installation place of the air-conditioner indoor unit (10), and the like. In other words, even when an obstacle is present in the inside of a room, the airflow of the “wide mode” easily flows around the obstacle. The temperature variation in the room is thus small.
In the air-conditioner indoor unit (10) according to the present embodiment, by the control unit (40) increasing the number of rotations of the fan (14) in the “wide mode” compared with before the “wide mode” is started, it is possible to maintain the blow-out velocity to be the same as that in the normal mode even when the range that is to be reached by the airflow is extended in the “wide mode” to be larger than that in the “normal mode”.
In the air-conditioner indoor unit (10) according to the present embodiment, by the control unit (40) reducing a difference between an intake temperature and a blow-out temperature in the “wide mode” compared with the “normal mode”, it is possible to further suppress a draft feeling than in the “normal mode” while maintaining the blow-out velocity without increasing the air conditioning capacity.
In the air-conditioner indoor unit (10) according to the present embodiment, by the control unit (40) switching to the “normal mode” when the “wide mode” has been continued for a predetermined period or more during cooling, it is possible to suppress occurrence of condensation in the air-conditioner indoor unit (10) during cooling.
In the air-conditioner indoor unit (10) according to the present embodiment, by the control unit (40) switching between the “normal mode” and the “wide mode” on the basis of presence/absence of a person inside and outside the range that is to be reached by the blow-out air of the “wide mode” in the air-conditioning target space, it is possible to perform appropriate air conditioning on the basis of a presence state of a person in the air-conditioning target space.
In the air-conditioner indoor unit (10) according to the present embodiment, by the control unit (40) causing the temperature of at least a portion of the heat exchanger (13) to be lower than a dew temperature in the air-conditioning target space in the “wide mode” during cooling, it is possible to perform cooling while dehumidifying.
In the air-conditioner indoor unit (10) according to the present embodiment, by the control unit (40) varying the velocity of the blow-out air in the “wide mode”, it is possible to blow out an airflow similar to comfortable natural wind.
The air-conditioner indoor unit (10) according to the present modification illustrated in
A rotary shaft (331) of the third wind-direction regulating plate (33) is provided in the vicinity of the center of the blow-out port (15) in the short-side direction. The base portion of the third wind-direction regulating plate (33) and the rotary shaft (331) are coupled together. The rotary shaft (331) is coupled to a rotary shaft of a motor (not illustrated) fixed to the body casing (11). The third wind-direction regulating plate (33) can be caused by the motor to take a plurality of orientations having different inclination angles in the front-rear direction.
By the rotary shaft (331) rotating counterclockwise in the front view in
In addition, in the air-conditioner indoor unit (10) according to the present modification illustrated in
In addition, to suppress separation of the airflow from the first wind-direction regulating plate (31), the first wind-direction regulating plate (31) is spaced from the terminal end (F) of the back-surface-side scroll (17), and a passage for the airflow is provided along the outer surface (31a) of the first wind-direction regulating plate (31).
In the “wide mode” of the air-conditioner indoor unit (10) according to the present modification, the control unit (40) changes the angle of the third wind-direction regulating plate (33) such that the airflow that is blown out through the blow-out port (15) separates on the inner surface (33b) of the third wind-direction regulating plate (33) and that the airflow is divided into two at the tip portion of the third wind-direction regulating plate (33). To suppress separation of the airflow from the first wind-direction regulating plate (31), the control unit (40) gradually changes the angle of the first wind-direction regulating plate (31) to be, for example, “33°→39°→45°” or “50°→55°→60°” and changes the angle of the third wind-direction regulating plate (33) such that the tip portion of the third wind-direction regulating plate (33) is positioned close to the first wind-direction regulating plate (31).
In the present modification described above, it is also possible to obtain the same effects as those in the aforementioned embodiment. In the present modification, by adding the third wind-direction regulating plate (33), the airflow that is blown out through the blow-out port (15) is divided into two, and a configuration similar to a configuration in which two blow-out ports are provided is realized. In detail, in a configuration in which the second wind-direction regulating plate (32) is provided to be continuous with the front-surface-side scroll (19) and in which the first wind-direction regulating plate (31) and the third wind-direction regulating plate (33) are provided between the front-surface-side scroll (19) and the back-surface-side scroll (17), an airflow on the upper side is generated by the front-surface-side scroll (19) and the third wind-direction regulating plate (33), and an airflow on the lower side is generated by the back-surface-side scroll (17), the first wind-direction regulating plate (31), and the third wind-direction regulating plate (33). Consequently, it is possible to vertically extend the range that is to be reached by the airflow in the air-conditioning target space.
In the present modification, the blow-out air is extended vertically by three horizontal wind-direction regulating plates (horizontal flaps). As an alternative to this, the blow-out air may be extended vertically by four or more horizontal flaps.
In the embodiment and the modification described above, the air-conditioner indoor unit (10) has, as blow-out modes, the “upward blowing mode”, the “oblique blowing mode”, the “wide mode”, and the “downward blowing mode” but may have different modes other than these modes additionally. Each of the “wide mode” and the other modes may have a plurality of sub-modes additionally. The range that is to be reached by the blow-out air of the “wide mode” in the air-conditioning target space may be movable in the height direction and the lateral direction (direction parallel to the long sides of the blow-out port (15)). The airflow that is blown out in the “wide mode” may be divided into two or more also in the lateral direction by providing a plurality of perpendicular wind-direction regulating plates such that the blow-out port (15) is demarcated into two or more regions in the long-side direction. Consequently, it is possible to extend the blow-out air also in the lateral direction and possible to reduce the variation in the wind velocity distribution of the blow-out air in the lateral direction.
In the embodiment and the modification described above, for example, when the state of air conditioning by the air-conditioner indoor unit (10) is stable, in other words, when the air conditioning load is relatively small, the control unit (40) may cause the air conditioning capacity of the “wide mode” to be lower than the air conditioning capacity of the “normal mode” when switching from the “normal mode” to the “wide mode”. Consequently, it is possible to immediately heat and cool the body of a user with a spread airflow that hits the whole body of the user while further suppressing a draft feeling by lowering the velocity of the wind that hits the user.
In the embodiment and the modification described above, the air-conditioner indoor unit (10) is a wall-mount type to be installed on a side wall in an air-conditioning target space. However, as long as having the “wide mode” according to the present disclosure, the air-conditioner indoor unit (10) may be of a different type, for example, a ceiling pendant type, a floor installation type, or the like.
Embodiments and modifications have been described above; however, it should be understood that the forms and the details can be variously changed without departing from the gist and the scope of the claims. The above embodiments and the modifications may be combined together or replaced, as appropriate, provided that intended functions of the present disclosure are not lost. The wordings “first”, “second”, . . . in the above description are used to distinguish the terms given these wordings from each other and do not intend to limit the numbers and the order of the terms.
As described above, the present disclosure is useful for an indoor unit for an air conditioner.
