Description

Air conditioner
Technical Field
The present invention relates to an air conditioner having an air cleaning filter.
Background
Japanese patent laying-open No. 2001-116282 discloses an air conditioner in which a plurality of louvers for opening and closing each having a vent hole are provided at an inlet of an indoor unit, and the louvers are integrated with an air cleaning filter. During the air cleaning operation, the plurality of louvers are in a closed state, and air sucked into the suction port is sucked through the air cleaning filter from the air holes provided in the plurality of louvers. On the other hand, during an air conditioning operation including a cooling operation and a heating operation, the plurality of louvers are in an open state, and air sucked into the suction port does not pass through the air cleaning filter.
Disclosure of Invention
However, in the conventional air conditioner, the air cleaning filter is integrated with the plurality of louvers. This causes a problem that the structure of the air conditioner is complicated.
The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide an air conditioner having an air cleaning function without complicating the structure and having high usability.
An air conditioner of the present invention for solving the problems of the prior art includes: a suction inlet; an air outlet; a fan that sucks in air from the suction port and blows out the air from the blow-out port; a heat exchanger for exchanging heat with the air; an air cleaning filter for removing dust contained in the air; and at least one part of the 1 plates can be separated from the main body at intervals, and the arrangement position of the air purification filter can be changed while the air purification filter is kept. The air conditioner of the invention has the 1 st operation mode that the heat exchanger carries on the heat exchange to the above-mentioned air; and a 2 nd operation mode in which the air passes through the air cleaning filter. In the 1 st operation mode, at least a part of the plate and the air cleaning filter are disposed at the 1 st position spaced apart from the main body. In the 2 nd operation mode, the air cleaning filter is disposed at the 2 nd position relatively closer to the main body than the 1 st position. The ventilation resistance of the air flow path in the 2 nd operation mode is increased as compared with the ventilation resistance of the air flow path in the 1 st operation mode because of the air cleaning filter.
Thus, during the air cleaning operation in the 2 nd operation mode, the air sucked from the air inlet port easily passes through the air cleaning filter, as compared with during the air conditioning operation in the 1 st operation mode. Thereby, high air purification performance can be obtained.
In addition, in the air conditioning operation as the 1 st operation mode, the air cleaning filter is spaced apart from the main body. This prevents the air blowing performance from being degraded during the air conditioning operation. Thus, the air conditioning performance is not degraded during the air conditioning operation, and the air conditioning efficiency is not degraded.
Further, the position at which the air cleaning filter is disposed is moved by the plate. Thus, an air conditioner having an air cleaning function and high usability can be provided without complicating the structure.
According to the present invention, an air conditioner having an air cleaning function and high usability can be provided without complicating the structure.

Detailed Description
The air conditioner of aspect 1 includes: a suction inlet; an air outlet; a fan that sucks in air from the suction port and blows out the air from the blow-out port; a heat exchanger for exchanging heat with the air; an air cleaning filter for removing dust contained in the air; and at least one part of the 1 plates can be separated from the main body at intervals, and the arrangement position of the air purification filter can be changed while the air purification filter is kept. The air conditioner of the invention has the 1 st operation mode that the heat exchanger carries on the heat exchange to the above-mentioned air; and a 2 nd operation mode in which the air passes through the air cleaning filter. In the 1 st operation mode, at least a part of the plate and the air cleaning filter are disposed at the 1 st position spaced apart from the main body. In the 2 nd operation mode, the air cleaning filter is disposed at the 2 nd position relatively closer to the main body than the 1 st position. The ventilation resistance of the air flow path in the 2 nd operation mode is increased as compared with the ventilation resistance of the air flow path in the 1 st operation mode because of the air cleaning filter.
Thus, during the air cleaning operation in the 2 nd operation mode, the air sucked from the air inlet port easily passes through the air cleaning filter, as compared with during the air conditioning operation in the 1 st operation mode. Thereby, high air purification performance can be obtained.
In addition, in the air conditioning operation as the 1 st operation mode, the air cleaning filter is spaced apart from the main body. This prevents the air blowing performance from being degraded during the air conditioning operation. Thus, the air conditioning performance is not degraded during the air conditioning operation, and the air conditioning efficiency is not degraded.
Further, the position at which the air cleaning filter is disposed is moved by the plate. Thus, an air conditioner having an air cleaning function and high usability can be provided without complicating the structure.
In the air conditioner according to claim 2, in particular, in claim 1, the 2 nd position is a position facing the suction port.
Thus, the air sucked from the suction port passes through the air cleaning filter before passing through the main body. Thereby, high air purification performance can be obtained.
The air conditioner according to claim 3 is characterized in that, in particular, in the air conditioner according to claim 1 or 2, the 2 nd position is a position not spaced apart from the main body.
Thus, the air cleaning filter is not spaced from the main body during the air cleaning operation in the 2 nd operation mode. Thus, the air cleaning filter is disposed in the flow path of the air sucked from the suction port, and therefore, the air blowing performance can be ensured, and high air cleaning performance can be obtained.
The air conditioner according to claim 4 is, particularly, one of the 1 st to 3 rd aspects, wherein in the 2 nd operation mode, at least a part of the plate is disposed at the 1 st position.
Thus, at least a part of the plate is disposed at a position away from the main body in the air cleaning operation as the 2 nd operation mode. This opens the panel, and reduces the air flow resistance.
The air conditioner according to claim 5 is, particularly, characterized in that the air conditioner according to any one of claims 1 to 4 further comprises an operation switch for instructing execution of the 2 nd operation mode, and the 2 nd operation mode is executed when the operation switch is operated.
Thus, when the user needs the air cleaning operation, the air cleaning operation as the 2 nd operation mode can be executed in accordance with the instruction of the user. Further, when the air cleaning operation as the 2 nd operation mode is not necessary or when the performance of the air conditioning operation as the 1 st operation mode and the energy saving performance are desired to be prioritized over the air cleaning operation as the 2 nd operation mode, the user can operate the operation switch to stop the air cleaning operation as the 2 nd operation mode. This improves the usability for the user.
The air conditioner according to claim 6 is, particularly, one of the air conditioners according to any one of the aspects 1 to 5, further comprising a dust detection sensor for detecting the dust contained in the air, wherein the 2 nd operation mode is executed when the dust detection sensor detects the dust.
This enables the air cleaning function in the 2 nd operation mode to be automatically enabled according to the degree of cleanliness of air.
The air conditioner according to claim 7 is, particularly, according to any one of claims 1 to 6, characterized in that the rotation speed of the fan set in the 2 nd operation mode is set to be greater than at least the lowest rotation speed of the fan set in the 1 st operation mode.
This can suppress a drop in the volume of blown air due to an increase in the ventilation resistance of the air cleaning filter. This ensures an air volume that can sufficiently exhibit the air purification function.
The air conditioner according to claim 8 is, particularly, one of the air conditioners according to any one of claims 1 to 7, wherein the plate has an air cleaning filter holding portion for holding the air cleaning filter, and the plate changes the arrangement position of the air cleaning filter while holding the air cleaning filter by the air cleaning filter holding portion.
Thus, the air cleaning filter moves while being held by the air cleaning filter holding portion. Thus, an air conditioner having an air cleaning function and high usability can be provided without complicating the structure.
The air conditioner according to claim 9 is particularly characterized in that, in any one of claims 1 to 8, the 1 st operation mode and the 2 nd operation mode can be operated simultaneously.
This makes it possible to perform the air conditioning operation as the 1 st operation mode and the air cleaning operation as the 2 nd operation mode. This makes it possible to maintain the room at a comfortable temperature and to purify the air in the room.
In the air conditioner according to claim 10, particularly according to claim 9, when the 1 st operation mode and the 2 nd operation mode are simultaneously operated, only one of the 1 st operation mode and the 2 nd operation mode can be stopped.
Thus, when the air-conditioning operation as the 1 st operation mode and the air-cleaning operation as the 2 nd operation mode are simultaneously operated, and only either one of the air-conditioning operation and the air-cleaning performance is required, it is not necessary to temporarily stop both the air-conditioning operation and the air-cleaning performance, and then start the operation of either one of the air-conditioning operation and the air-cleaning operation. This improves the usability for the user.
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiment.
(embodiment mode 1)
Fig. 1 to 3 are views showing an example of a vertical cross section of an indoor unit of an air-conditioning apparatus 1000 according to embodiment 1.
The air conditioner 1000 of the present embodiment is composed of an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected by a refrigerant pipe and a control wiring. The indoor unit and the outdoor unit constitute a heat pump. The outdoor unit has a compressor. The indoor unit is installed on an indoor wall surface.
In this configuration, in a state where the indoor unit of the air-conditioning apparatus 1000 is mounted on a wall surface in a room, one side relatively close to the wall surface is set to be the rear side, and the opposite side to the rear side is set to be the front side. In a state where the indoor unit of the air-conditioning apparatus 1000 is attached to an indoor wall surface, the left side and the right side of the indoor unit when viewed from the front are the left and right sides, respectively. Further, in a state where the indoor unit of the air-conditioning apparatus 1000 is mounted on an indoor wall surface, the upper side of the indoor unit as viewed from the front is set to the upper side, and the lower side is set to the lower side.
The above definitions of the front-back direction, the left-right direction, and the up-down direction are provided to make it easy for those skilled in the art to understand the present invention, and only the relative positional relationship is shown.
The indoor unit of the air conditioner 1000 of the present embodiment includes a main body 1 and a front panel 2.
The main body 1 has a suction port 11A, a suction port 11B, and a discharge port 12. The suction port 11A is formed on the upper surface of the main body 1. The suction port 11B is formed in the front surface of the main body 1. The air outlet 12 is formed in the lower surface of the main body 1. The rear surface 13 of the body 1 is mounted to a wall surface.
The front panel 2 is provided on the front surface of the main body 1 to open and close the suction port 11B. The front panel 2 has a front panel opening/closing portion (not shown) for separating from the main body 1.
As shown in the present embodiment, the front panel 2 may be such that the entire front panel 2 does not separate from the main body 1. For example, in a state where a part of the front panel 2 is pivotally supported by the main body 1, a part of the front panel 2 pivotally supported by the main body 1 may be rotated so that another part of the front panel 2 is separated from the main body 1.
Further, the main body 1 has, inside the main body 1: a fan 20 that sucks air into the main body 1 through the suction ports 11A and 11B and blows out the air from the blow-out port 12; and a heat exchanger 30 that exchanges heat with air drawn in from the suction ports 11A and 11B. Further, the fan 20 is preferably a cross flow fan (cross flow fan). A fan motor (not shown) is coupled to at least one of the left and right ends of the rotation shaft of the fan 20.
A downstream air flow path 40 is provided from the downstream of the fan 20 to the upstream of the air outlet 12. The downstream air flow path 40 is formed by a rear guide 41 disposed downstream of the fan 20 to guide the flow of air, a stabilizer 42 disposed opposite to the rear guide 41, and left and right side walls (not shown) of the main body 1.
The 1 st louver 51 and the 2 nd louver 52 are disposed in the air outlet 12. The 1 st louver 51 opens and closes the air outlet 12, and changes the air blowing direction in the vertical direction. The 2 nd louver 52 changes the blowing direction of the air in the left-right direction. The 2 nd louver 52 is disposed upstream of the 1 st louver 51 with respect to the main body 1.
The heat exchanger 30, the air filter 70, and the air cleaning filter 80A are disposed in the air flow path 60 and the air flow path 61 on the upstream side of the fan 20. The air filter 70 and the air cleaning filter 80A are separate bodies. The air filter 70 is a filter for so-called coarse dust, which is intended to capture relatively large dust. On the other hand, the air cleaning filter 80A has a larger ventilation resistance than the air filter 70 and is intended to capture fine particles passing through the air filter 70. The air cleaning filter 80A is preferably of a pleated or non-woven fabric type.
The air cleaning filter 80A is held by at least one of a main body side filter holding portion (not shown) of the main body 1 and a board side filter holding portion 81 of the front panel 2. Air cleaning filter 80A is disposed at a position facing intake port 11B of air flow path 60. The main body side filter holding portion and the plate side filter holding portion 81 hold or release the air cleaning filter 80A as necessary.
The air cleaning filter 80A is disposed in the air flow path 60 on the upstream side of the air filter 70. When the air cleaning filter 80A is disposed in the air flow path 60, it is possible to suppress the performance degradation of the air cleaning filter 80A due to dew condensation during the cooling operation, as compared to when the air cleaning filter 80A is disposed in the air flow path 61 between the air filter 70 and the heat exchanger 30.
The air conditioner 1000 of the present embodiment is capable of performing an air conditioning operation and an air cleaning operation including at least one of a cooling operation and a heating operation. These operations are switched by the operation device 100 by the user instructing the air conditioner 1000 to switch the operations.
The operation device 100 includes an operation switch 101 that instructs a cooling operation, an operation switch 102 that instructs a heating operation, and an operation switch 103 that instructs an air cleaning operation.
For example, when the user operates the operation switch 101 that instructs the cooling operation, the air conditioner 1000 performs an operation of separating the front panel 2 from the main body 1, that is, an operation of turning on the front panel 2, and performs the cooling operation as the air conditioning operation. When the user operates the operation switch 102 for instructing the heating operation, the air conditioner 1000 also performs the same operation as in the above case, and performs the heating operation as the air conditioning operation. The operation of opening the front panel 2 may be referred to as an opening operation of the front panel 2.
When the user operates either the operation switch 101 or the operation switch 102 to perform the air conditioning operation of the air conditioner 1000, the air cleaning filter 80A moves in a direction away from the main body 1 together with the operation of the front panel 2. In this state, when the user operates either the operation switch 101 or the operation switch 102 operated by the user again, the stop of the operation is instructed to the air conditioner 1000. Thus, the air conditioner 1000 performs an operation of relatively moving the front panel 2 closer to the main body 1, that is, an operation of closing the front panel 2. At this time, the air cleaning filter 80A moves from a position away from the main body 1 to a direction relatively close to the main body 1 together with the operation of closing the front panel 2, is disposed at a position facing the suction port 11B of the air flow path 60, and the air conditioning operation is stopped. The operation of closing the front panel 2 may be referred to as a closing operation of the front panel 2.
For example, when the user operates the operation switch 103 for instructing the air cleaning operation, the air conditioner 1000 performs the opening operation of the front panel 2 while maintaining the state in which the air cleaning filter 80A is disposed at a position facing the air inlet 11B of the air flow path 60. Thus, the air conditioner 1000 performs an air cleaning operation in which the air cleaning function is effective.
The air conditioner 1000 of the present embodiment includes a dust detection sensor 110 that detects dust contained in air. The air conditioner 1000 may start the air cleaning operation based on the result of the degree of cleanliness of the air detected by the dust detection sensor 110.
For example, when the air-conditioning operation and the air-cleaning operation are started when the air-conditioning operation is stopped, the air-conditioning apparatus 1000 performs the opening operation of the front panel 2 while keeping the air-cleaning filter 80A at the position facing the air inlet 11B of the air flow path 60, and starts the air-cleaning operation.
Further, for example, when the air cleaning operation is started in a state where the air cleaning operation is not performed during the air conditioning operation, the air cleaning filter 80A is moved in a direction relatively closer to the main body 1 from a state where it is separated from the main body 1 together with the front panel 2, and is disposed at a position facing the suction port 11B of the air flow path 60. At this time, the front panel 2 does not move.
According to the present embodiment, the air conditioner 1000 can automatically perform an air cleaning operation for enabling an air cleaning function in response to the degree of cleanliness of air detected by the dust detection sensor 110, that is, in the presence of dust.
For example, when the front panel 2 and the air cleaning filter 80A are moved and disposed at positions away from the main body 1 during the air conditioning operation, it can be said that the front panel 2 and the air cleaning filter 80A are disposed at the 1 st position, respectively. For example, when the front panel 2 and the air cleaning filter 80A are disposed at positions facing the suction port 11B of the air flow path 60 during stoppage of operation, it can be said that the front panel 2 and the air cleaning filter 80A are disposed at the 2 nd position, respectively. In this case, the 2 nd position can be said to be a position not separated from the main body 1.
For example, when the front panel 2 is moved and disposed at a position away from the main body 1 and the air cleaning filter 80A is disposed at a position facing the suction port 11B of the air flow path 60 during the air cleaning operation, it can be said that the front panel 2 is disposed at the 1 st position and the air cleaning filter 80A is disposed at the 2 nd position. At this time, the 2 nd position can be said to be relatively closer to the main body 1 than the 1 st position.
For example, the 1 st position of the front panel 2 during the air conditioning operation is preferably the same as the 1 st position of the front panel 2 during the air cleaning operation.
However, the same position is not necessarily required, and a position apart from the main body 1 may be used. For example, the 2 nd position of the air cleaning filter 80A during the operation stop and the 2 nd position of the air cleaning filter 80A during the air cleaning operation are not necessarily the same position, and may be a position facing the suction port 11B of the air flow path 60.
As described above, the air conditioner 1000 of the present embodiment has at least one of the air conditioning operation as the 1 st operation mode and the air cleaning operation as the 2 nd operation mode. During the air conditioning operation, the air cleaning filter 80A and the front panel 2 are both disposed at positions away from the main body 1. Accordingly, the air sucked from the suction ports 11A and 11B passes through the air filter 70 and is heat-exchanged by the heat exchanger 30. During the air cleaning operation, the air cleaning filter 80A is disposed at a position facing the suction port 11B of the air flow path 60, and the front panel 2 is disposed at a position away from the suction port 11B of the main body 1. Thereby, at least a part of the air sucked from suction port 11A and suction port 11B passes through air cleaning filter 80A, air filter 70, air cleaning filter 80A, and heat exchanger 30. Further, the air conditioning operation and the air cleaning operation can be simultaneously operated.
The rotation speed of the fan 20 set in the air cleaning operation is set to be greater than at least the lowest rotation speed of the fan 20 set in the air conditioning operation. For example, when the rotation speed of the fan 20 in the air conditioning operation is changed to "weak", "medium", or "strong", the rotation speed of the fan 20 set in the air cleaning operation may be at least the rotation speed of "medium" or a rotation speed smaller than the rotation speed of "medium" that is larger than the rotation speed of "weak".
By setting the rotation speed of the fan 20 set in the air cleaning operation to be greater than at least the lowest rotation speed of the fan 20 set in the air conditioning operation in this way, it is possible to suppress a decrease in the volume of air blown out from the air outlet 12 due to an increase in the air resistance of the air cleaning filter 80A. This ensures an air volume that sufficiently exhibits the air purification function.
The main body 1 is provided with a display unit (not shown) for showing an operation of the air cleaning function. The display unit may be located in the operation device 100, or may be located in both the main body 1 and the operation device 100.
The operation of the air conditioner 1000 configured as described above will be described below. In both the air conditioning operation and the air cleaning operation, the 1 st louver 51 opens the air outlet 12, but fig. 1 to 3 show an example of a state in which the 1 st louver 51 closes the air outlet 12, and show only an example of the operation of the front panel 2 and the air cleaning filter 80A.
Fig. 1 is a diagram showing an example of a vertical cross section of an indoor unit of an air-conditioning apparatus 1000 when an air-conditioning operation as a 1 st operation mode and an air-cleaning operation as a 2 nd operation mode are stopped.
When the air conditioning operation is stopped, the air cleaning filter 80A is held by at least one of the main body side filter holding portion of the main body 1 and the panel side filter holding portion 81 of the front panel 2. Thus, air cleaning filter 80A is disposed at a position facing intake port 11B of air flow path 60. The main body side filter holding unit and the plate side filter holding unit 81 can select a holding state for holding the air cleaning filter 80A and a releasing state for releasing the air cleaning filter 80A, as necessary.
Fig. 2 is a diagram showing an example of a vertical cross section of an indoor unit of the air-conditioning apparatus 1000 in the air-conditioning operation as the 1 st operation mode.
Fig. 2 shows a state in which the front panel 2 and the air cleaning filter 80A are disposed at positions away from the main body 1, that is, a state in which the front panel 2 is opened together with the air cleaning filter 80A.
The main body side filter holding unit releases the air cleaning filter 80A, and the plate side filter holding unit 81 holds the air cleaning filter 80A. In this state, the front panel 2 is opened, and the state during the air conditioning operation shown in fig. 2 is obtained. The opening and closing operation of the front panel 2 is performed by a front panel opening and closing unit.
For example, when the user operates the operation switch 101, the cooling operation is started. For example, when the user operates the operation switch 102, the heating operation is started. When the cooling operation and the heating operation, which are the air conditioning operation, are started, the front panel 2 and the air cleaning filter 80A are in the air conditioning operation state of fig. 2 from the operation stop state of fig. 1, and the fan 20 and the compressor are operated. Thereby, the air conditioning operation is started. When fan 20 starts operating, air is sucked from suction port 11A and suction port 11B. The sucked air passes through the air filter 70 and the heat exchanger 30, and is blown out from the air outlet 12.
However, the air cleaning filter 80A is located outside the air flow path 60 with respect to the main body 1. Thus, the air sucked from suction port 11A and suction port 11B does not pass through air cleaning filter 80A. That is, the air cleaning filter 80A does not obstruct ventilation. This prevents the air blowing performance from being degraded during the air conditioning operation. That is, the air conditioning performance does not decrease and the air conditioning efficiency does not deteriorate during the air conditioning operation.
Fig. 3 is a diagram showing an example of a vertical cross section of an indoor unit of the air-conditioning apparatus 1000 in the air-cleaning operation as the 2 nd operation mode.
Fig. 3 shows a state in which air cleaning filter 80A is disposed at a position facing intake port 11B of air flow path 60, and front panel 2 is moved in a direction away from intake port 11B of main body 1 and disposed at a position away from intake port 11B of main body 1. That is, the front panel 2 is in an open state.
The main body side filter holding portion holds the air cleaning filter 80A. The plate-side filter holding portion 81 releases the air cleaning filter 80A. In this state, the front panel 2 is opened, and the state during the air cleaning operation shown in fig. 3 is obtained.
For example, when the user operates the operation switch 103, the air cleaning operation is started. When the air cleaning operation is started, the front panel 2 and the air cleaning filter 80A are in the air cleaning operation state shown in fig. 3 from the stop state shown in fig. 1, and the fan 20 is operated. This starts the air cleaning operation and the display unit starts displaying.
When fan 20 is operated, at least a part of the air sucked from suction port 11A and suction port 11B passes through air cleaning filter 80A, and is cleaned. The air having passed through air cleaning filter 80A passes through air filter 70 and heat exchanger 30, and is blown out from blow-out port 12. The air blown out from the air outlet 12 is purified by the air purifying filter 80A. This can purify the indoor air.
Here, since at least a part of the air sucked from suction port 11A and suction port 11B passes through air cleaning filter 80A, the ventilation resistance is higher than that in the air conditioning operation of fig. 2, and the air volume is reduced. However, during the air cleaning operation, the air cleaning filter 80A is disposed at a position facing the suction port 11B of the air flow path 60.
That is, the surface area of the passage surface of air cleaning filter 80A through which the air sucked from suction port 11A and suction port 11B passes can be maximized. Alternatively, the surface area of the passage surface of air cleaning filter 80A through which the air sucked from suction port 11A and suction port 11B passes can be made larger than that during the air conditioning operation of fig. 2.
This increases the volume of air sucked from suction port 11A and suction port 11B and passing through air cleaning filter 80A during the air cleaning operation. Alternatively, the air volume of the air sucked from suction port 11A and suction port 11B and passing through air cleaning filter 80A during the air cleaning operation is larger than the air volume of the air sucked from suction port 11A and suction port 11B and passing through air cleaning filter 80A during the air conditioning operation. Thus, during the air cleaning operation, the air sucked through the suction port 11B passes through the air cleaning filter 80A more easily than during the air conditioning operation.
Further, during the air cleaning operation, only the front panel 2 is disposed at a position away from the suction port 11B of the main body 1, that is, the front panel 2 is in an open state. This can reduce the resistance when the air passes through the air cleaning filter 80A. Thus, the air conditioner 1000 can easily secure the air volume during the air cleaning operation, and can obtain high air cleaning performance.
Further, when the air-conditioning operation and the air-cleaning operation are simultaneously performed by the air-conditioning apparatus 1000, it is easy to ensure the air volume. Thereby, both the air purification performance and the air conditioning performance can be optimized.
Further, when only the air-cleaning operation is performed, or when the air-conditioning operation and the air-cleaning operation are simultaneously performed, the air-conditioning apparatus 1000 can increase the volume of air reduced by the ventilation resistance of the air-cleaning filter 80A by setting the rotation speed of the fan 20 to be higher than that in the case of only the air-conditioning operation. As a mode of the display portion, for example, a method of repeating lighting and turning off of a lamp such as an LED (light emitting diode) can be considered.
When the user operates the operation switch 101 or the operation switch 102 during the air cleaning operation, the air conditioner 1000 keeps performing the air cleaning operation in the state of the air cleaning operation shown in fig. 3, and starts the cooling operation or the heating operation. That is, from the state in which the fan 20 is operated during the air cleaning operation, the compressor starts to operate, and the air conditioning operation, which is the cooling operation or the heating operation, is started. This makes it possible to perform the air conditioning operation and the air cleaning operation. This allows the air conditioner 1000 to keep the indoor temperature comfortable and to purify the indoor air.
When the user operates the operation switch 103 during the cooling operation or the heating operation, the air conditioner 1000 switches from the state of the air conditioning operation shown in fig. 2 to the state of the air cleaning operation shown in fig. 3, and starts the air cleaning operation while the air conditioning operation is being maintained. During the air conditioning operation, the fan 20 and the compressor are held in operation, and the air cleaning filter 80A is moved in a direction relatively closer to the main body 1 from the state held on the back surface of the front panel 2 by the panel-side filter holding unit 81, and is disposed at a position facing the suction port 11B of the air flow path 60. As a result, the air conditioning operation can be performed while the air cleaning operation is performed, as described above.
Further, when the air conditioning operation and the air cleaning operation are simultaneously operated, the user operates the operation device 100, whereby the air conditioner 1000 can stop only the operation of either the air conditioning operation or the air cleaning operation. In addition, when the air conditioning operation and the air cleaning operation are simultaneously operated, the air conditioner 1000 can stop only the air cleaning operation by the operation of the user when the air conditioner capacity is required or when the energy saving operation is performed in order to improve the operation efficiency of the air conditioning operation. Further, when the air conditioning operation and the air cleaning operation are simultaneously operated, the air conditioner 1000 may stop only the air conditioning operation by the operation of the user when the air cleaning capability is required.
Thus, when only either the air conditioning operation or the air purification performance is required during the simultaneous operation of the air conditioning operation and the air purification operation, the user does not need to temporarily stop both the air conditioning operation and the air purification performance and then start the operation of either the air conditioning operation or the air purification operation. This improves the usability for the user.
The air conditioner 1000 of the present embodiment includes a dust detection sensor 110 and detects the degree of cleanliness of air. When the air conditioner 1000 executes the air conditioning operation and stops the air cleaning operation and the low degree of cleanliness is detected, the air cleaning operation can be automatically started by a control unit (not shown) included in the air conditioner 1000.
In addition, regardless of whether the air conditioning operation is executed or not, the air conditioner 1000 can automatically stop the air cleaning operation by the control unit when the dust detection sensor 110 detects that the degree of cleanliness of the air in the room is high during the air cleaning operation. Further, the air conditioner 1000 can change the air cleaning capacity by changing the rotation speed of the fan 20 while maintaining the air cleaning operation, by the control unit, instead of starting or stopping the air cleaning operation according to the degree of cleanliness of the air in the room.
Further, in the air conditioner 1000 of the present embodiment, the air cleaning filter 80A is disposed at a position facing the suction port 11B of the air flow path 60 and is separated from the main body 1 together with the front panel 2, but the air cleaning filter 80A may be disposed at a position facing the suction port 11A of the air flow path 60, a top panel for opening and closing the suction port 11A may be provided, and the air cleaning filter 80A may be separated from the main body 1 together with the top panel.
As described above, the air conditioner 1000 according to the present invention can enhance the durability of the air cleaning filter while enabling the air cleaning function to be effective as needed, and thus is suitable for use not only in household applications but also in industrial applications.
