Description

[Technical Field]

[0001] The present invention relates to an air conditioning device. [Background technology]

[0002] Patent Document 1 discloses a dehumidifier, which is a type of air conditioning device. The dehumidifier of Patent Document 1 can automatically switch between high and low output and enable or disable functions of the dehumidifier without requiring an operator (user) to do so. Furthermore, when it becomes dark, the dehumidifier of Patent Document 1 reduces output and disables certain functions compared to when the surroundings are bright, in order to reduce the amount of sound and light emitted from the dehumidifier. In other words, the functions of the dehumidifier of Patent Document 1 are limited in dark environments. Hereinafter, reducing output to a certain level or below or disabling certain functions will be referred to as "limiting functions." [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-142625 Summary of the Invention [Problem to be solved by the invention]

[0004] The dehumidifier of Patent Document 1 uniformly limits its functions in any dark environment. However, even in a dark environment, for example, if there is no user around the dehumidifier, there is no need to suppress the noise generated by the device. Therefore, in such a situation, the dehumidifier of Patent Document 1 has the problem of excessively limiting its functions.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an air conditioning device that can identify situations in dark environments and change the degree of function restriction depending on the identified situation. [Means for solving the problem]

[0006] According to one aspect of the present invention, an air conditioning device includes an apparatus main body, an illuminance sensor, and a control unit. The apparatus main body has an inlet for drawing air into the inside and an outlet for blowing the drawn air out. The illuminance sensor detects light around the apparatus main body. The control unit controls at least one of the magnitude of output exerted by a function of the air conditioning device and switching between enabling and disabling the function based on the illuminance detected by the illuminance sensor. The control unit includes a first restriction unit and a first release unit. The first restriction unit imposes a first restriction on the function when the illuminance detected by the illuminance sensor is less than a first predetermined illuminance. When the first restriction is imposed on the function, the first release unit releases at least a portion of the first restriction when the illuminance sensor continuously detects an illuminance less than the first predetermined illuminance for a first predetermined time or more. [Effects of the Invention]

[0007] According to the present invention, in the air conditioning device, the first release unit identifies a situation in a dark environment when the illuminance sensor continuously detects illuminance below a first predetermined illuminance for at least a first predetermined time. Having identified a situation in a dark environment, the first release unit releases part of the control that restricts the functions of the air conditioning device, and can change the degree of restriction on the functions to be exercised depending on the situation.

[0009] Hereinafter, embodiments will be described with reference to the drawings. In the drawings, the same or corresponding parts will be designated by the same reference numerals, and description thereof will not be repeated. In addition, to facilitate understanding of the drawings, in this embodiment, front, back, left, right, up and down directions will be appropriately described.

[0010] [Embodiment 1] An air conditioner 1 according to embodiment 1 will be described with reference to Fig. 1 to Fig. 3. Fig. 1 is a perspective view showing the air conditioner 1 according to embodiment 1. Fig. 2 is a block diagram showing the air conditioner 1 according to embodiment 1. Fig. 3 is a flowchart showing the processing of the air conditioner 1 according to embodiment 1.

[0011] The air conditioner 1 shown in Fig. 1 has an air conditioning function that adjusts the physical properties of air. The air conditioning function includes, for example, an air purification function, a humidification function, a dehumidification function, a cooling function, a heating function, an ion generation function, an air conditioning function, or a combination of these functions.

[0012] The air purification function is a function that removes harmful particles from the air present around the air conditioner 1. An air conditioner 1 with an air purification function draws in air around the air conditioner 1, removes harmful particles contained in the drawn-in air, and blows out the air. Thus, harmful particles are removed from the air around the air conditioner 1. Harmful particles include, for example, dust or odorous components. Dust includes, for example, fine particles such as PM2.5 with a particle size smaller than 3 μm. Odorous components include, for example, acetaldehyde, ammonia, or acetic acid.

[0013] The humidification function is a function that increases the humidity of the air present around the air conditioning device 1. An air conditioning device 1 with a humidification function draws in air present around the air conditioning device 1, humidifies the drawn-in air, and blows it out. Therefore, the humidity of the air present around the air conditioning device 1 increases. The dehumidification function is a function that decreases the humidity of the air present around the air conditioning device 1. An air conditioning device 1 with a dehumidification function draws in air present around the air conditioning device 1, removes moisture contained in the drawn-in air, and blows it out. Therefore, the humidity of the air present around the air conditioning device 1 decreases.

[0014] The air conditioning function is a function that adjusts the temperature of the air present around the air conditioner 1 to a desired temperature. An air conditioner 1 with an air conditioning function draws in the air present around the air conditioner 1, adds heat to the drawn-in air, or removes heat from the drawn-in air and blows it out. Therefore, the temperature of the air present around the air conditioner 1 rises or falls.

[0015] An air conditioning device 1 will be described with reference to FIGS. 1 and 2. As shown in FIGS. 1 and 2, the air conditioning device 1 includes a device main body 2 (see FIG. 1), an air conditioning unit 3 (see FIG. 2), a notification unit 41, a maintenance unit 42, an illuminance sensor 51, an operation unit 6, a control unit 7 (see FIG. 2), and a storage unit 81 (see FIG. 2). The air conditioning unit 3 is housed inside the device main body 2. The air conditioning unit 3 is a part that performs the air conditioning function. The notification unit 41 notifies the user of information related to the operation of the air conditioning unit 3. The maintenance unit 42 performs maintenance of the air conditioning unit 3. The illuminance sensor 51 is provided outside the device main body 2 and detects illuminance. The illuminance sensor 51 outputs the detected illuminance to the control unit 7. The operation unit 6 accepts operations from the user. The operation unit 6 outputs the operations accepted from the user to the control unit 7. The control unit 7 cooperates with the storage unit 81 to control the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 based on the output from the illuminance sensor 51 and the output from the operation unit 6.

[0016] The device body 2 is a hollow housing. The device body 2 is made of a material such as metal or synthetic resin. However, the material of the device body 2 is not particularly limited. As shown in FIG. 1, the device body 2 includes a front cover 21, a rear cover 23, a pair of left and right side covers 22, a middle cover 24, and a top cover 25. Note that only one of the pair of middle covers 24 is shown in FIG. 1, and the other of the pair of middle covers 24 is hidden.

[0017] The front cover 21 is disposed opposite the rear cover 23. The height of the rear cover 23 is greater than that of the front cover 21. The rear cover 23 is provided with an inlet 2A that connects the inside and outside of the device main body 2. Air present around the air conditioning device 1 is drawn into the inside of the device main body 2 through the inlet 2A. Each of the pair of side covers 22 connects the front cover 21 and the rear cover 23. Each of the pair of side covers 22 is provided with a handle 221. The middle cover 24 connects the front cover 21, the rear cover 23, and the upper parts of the pair of side covers 22. Here, as described above, the height of the rear cover 23 is greater than the height of the front cover 21, so the middle cover 24 connects the rear cover 23 and the front cover 21 in an orientation that slopes downward from the rear to the front. The middle cover 24 is provided with a first air outlet 2B that connects the inside and outside of the device main body 2. Top cover 25 is disposed so as to protrude forward from an upper portion of rear cover 23, a portion of an upper portion of middle cover 24, and a portion of an upper portion of the pair of side covers 22. Top cover 25 is provided with a second air outlet 2C that connects the inside and outside of device body 2. Air drawn into device body 2 is blown out to the outside of device body 2 through first air outlet 2B of middle cover 24 and second air outlet 2C of top cover 25.

[0018] As shown in FIG. 2, the air conditioning unit 3 has a blower unit 31 and an action unit 32. The blower unit 31 is arranged inside the device body 2. The blower unit 31 arranged inside the device body 2 blows air. When the blower unit 31 blows air, an airflow (not shown) is generated in which air present around the device body 2 is sucked into the device body 2 through the intake port 2A, an airflow (not shown) passes through the inside of the device body 2, and an airflow (not shown) in which the air that has passed inside the device body 2 is blown out to the outside of the device body 2 through the first outlet 2B and the second outlet 2C.

[0019] The amount of air blown by blower 31 is controlled by combining multiple elements. The multiple elements include, for example, the type of operation received by controller 7 and the output of sensors provided in air conditioning device 1. The sensors provided in air conditioning device 1 include illuminance sensor 51. By having blower 31 blow the amount of air determined by controller 7 by combining multiple elements, it is possible to change the amount of air drawn into device main body 2 and the amount of air blown out from device main body 2 depending on the user's operation or the conditions around device main body 2.

[0020] The action unit 32 is disposed on the path of the airflow passing through the inside of the device main body 2. The action unit 32 acts on the air passing through the action unit 32 to change the physical properties of the air. Specifically, the action unit 32 performs at least one of the following functions on the air that has passed through the action unit 32: removing harmful particles, humidifying, dehumidifying, or conditioning the air. The amount of air whose physical properties are changed by the operation of the action unit 32 increases in proportion to the amount of air blown by the blower unit 31. Meanwhile, the sound generated by the blower unit 31 also increases in proportion to the amount of air blown by the blower unit 31. Therefore, it is preferable to set or limit the upper limit of the amount of air blown by the blower unit 31 depending on circumstances, such as when the environment in which the device main body 2 is installed is unfavorable.

[0021] The notification unit 41 is provided inside or outside the device main body 2. The notification unit 41 notifies information related to the operation of the air conditioning unit 3. The information related to the operation of the air conditioning unit 3 includes information related to the state of the air conditioning unit 3, errors occurring in the air conditioning unit 3, and information received by the air conditioning device 1 from outside. The information related to the state of the air conditioning unit 3 includes the type of operation received by the operation unit 6, the type of air conditioning function being operated, and the detection status of the sensors provided in the air conditioning device 1. The operations received by the operation unit 6 will be described later. The information received by the air conditioning device 1 from outside is information related to the state of the air conditioning unit 3. The information related to the state of the air conditioning unit 3 is, for example, information about the air in the location where the air conditioning device 1 is installed. Specifically, it includes information such as the weather forecast for the location where the air conditioning device 1 is installed.

[0022] The notification unit 41 has a lamp 411 and a speaker 412 (see FIG. 2). The lamp 411 is provided on the outside of the device main body 2. The lamp 411 notifies information related to the state of the air conditioning unit 3 and any errors occurring in the air conditioning unit 3. The speaker 412 is provided inside the device main body 2. The speaker 412 notifies all information related to the state of the air conditioning unit 3.

[0023] The lamps 411 include a status display lamp 41A and a warning lamp 41B (see FIG. 1). The lamps 411 display a pattern according to the content to be notified, and turn on and off. The lamps 411 light up at a first brightness to notify the content assigned to the lit lamp 411.

[0024] Status indicator lamps 41A are provided on the top cover 25 of the device main body 2 and the front cover 21 of the device main body 2. The status indicator lamps 41A arranged on the top cover 25 of the device main body 2 are assigned information relating to the status of the air conditioning unit 3, for example. Specifically, the status indicator lamp 41A provided on the top cover 25 in FIG. 1 that is lit indicates that the air conditioning device 1 is in an operating state. On the other hand, the status indicator lamps 41A provided on the front cover 21 that are lit indicate which functions are enabled in the air conditioning device 1.

[0025] Warning lamp 41B is provided on the front cover 21 of the device main body 2. Warning lamp 41B arranged on the front cover 21 of the device main body 2 notifies that an error has occurred in the air conditioning unit 3. Specifically, for example, warning lamp 41B provided on the front cover 21 in Fig. 1 and lit up notifies that there is not enough water in a tank (not shown) provided in the air conditioning device 1 to operate the humidification function.

[0026] The speaker 412 shown in FIG. 2 notifies all information related to the air conditioning unit 3 by emitting sounds or voices.

[0027] The maintenance unit 42 is a part that performs maintenance on the air conditioning unit 3. After the air conditioning unit 3 has been operating for a certain period of time, its ability to perform its air conditioning function decreases. The decrease in the capacity of the air conditioning unit 3 occurs, for example, when dust floating in the air accumulates on the components that make up the air conditioning unit 3. The maintenance unit 42 operates by removing factors that reduce the capacity of the air conditioning unit 3, so that the capacity of the air conditioning unit 3 is always at a certain level or above. However, when the maintenance unit 42 starts operating, noise is generated from the maintenance unit 42 due to the maintenance operation. The noise generated by the maintenance unit 42 may be undesirable in some situations.

[0028] For example, the air conditioning unit 3 with an air purification function is equipped with a filter (not shown) that removes harmful particles from the air. After a certain period of use, harmful particles accumulate on the filter, reducing its ability to remove harmful particles from the air. The maintenance unit 42 is a part that removes harmful particles that have accumulated on the filter.

[0029] Specifically, the maintenance unit 42 is composed of, for example, a brush (not shown) that can contact the surface of the filter from which harmful particles are to be removed, and a roller (not shown) that winds up the filter. As the roller winds up the filter, the brush slides over the surface from which harmful particles are to be removed, entangling harmful particles that have adhered to the filter. The roller then rotates in the reverse direction, and the filter is returned to its original position with the harmful particles removed from the surface from which harmful particles are to be removed. During the series of operations from the roller winding up the filter to the filter being returned to its original position as described above, noise is generated by the movement of the roller, etc. The noise generated by the movement of the roller, etc., is undesirable, for example, when the user is sleeping, as it can disturb the user's sleep.

[0030] As shown in FIG. 1, the illuminance sensor 51 is provided on the top cover 25. The illuminance sensor 51 detects light around the device body 2 and outputs a signal corresponding to the illuminance. The illuminance sensor 51 is a sensor including an element that converts received light into an electric current, such as a phototransistor or a photodiode. The illuminance sensor 51 outputs a signal corresponding to the illuminance to the control unit 7 (see FIG. 2). Note that the installation position of the illuminance sensor 51 is not limited to the top cover 25, as long as it can detect the illuminance around the device body 2.

[0031] The operation unit 6 is provided on the top cover 25. The operation unit 6 is composed of a plurality of operation buttons 61. When the user presses the operation button 61, the operation unit 6 accepts the user's operation. The operation unit 6 outputs the user's operation to the control unit 7.

[0032] The operations received by the operating unit 6 include "modes," which are instructions that stipulate the functions to be exercised by the air conditioning device 1. The modes include a constant operation mode, an automatic operation mode, and a function disabled mode. The constant operation mode is a mode in which the air conditioning unit 3 exerts a constant output regardless of the conditions surrounding the device main body 2. The automatic operation mode is a mode in which at least one of the magnitude of the output of the functions possessed by the air conditioning device 1 or the switching between enabling and disabling of the functions possessed by the air conditioning device 1 is controlled in accordance with the conditions surrounding the device main body 2, such as the physical properties of the air around the device main body 2 or the illuminance. The function disabled mode is a mode in which the air conditioning device 1 operates with certain functions possessed by the air conditioning device 1 disabled.

[0033] As shown in FIG. 2 , the control unit 7 controls the air conditioning unit 3, the notification unit 41, the maintenance unit 42, and the memory unit 81. The control unit 7 includes a processor such as a CPU (Central Processing Unit). The memory unit 81 includes a storage device and stores data and computer programs. Specifically, the storage unit 81 includes a main storage device such as a semiconductor memory and an auxiliary storage device such as a semiconductor memory, a solid-state drive, and a hard disk drive. The storage unit 81 may also include removable media. The processor of the control unit 7 executes a computer program stored in the storage device of the storage unit 81 to control the air conditioning unit 3, the notification unit 41, the maintenance unit 42, and the memory unit 81. The control of the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 is performed based on the mode setting output to the control unit 7 by the operation unit 6. The control unit 7 also receives an input of illuminance detected by an illuminance sensor 51. The control unit 7 refers to the illuminance detected by the illuminance sensor 51 and controls the air conditioning unit 3, the notification unit 41, and the maintenance unit 42.

[0034] When the aforementioned automatic operation mode is set, the control unit 7 controls the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 so that the air conditioning device 1 operates in one of the following states: a normal state, a first restricted state, or a second restricted state, depending on the illuminance detected by the illuminance sensor 51. The normal state is a state in which the air conditioning device 1 operates without any restrictions on the functions exerted by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42. The first restricted state is a state in which the air conditioning device 1 operates with a first restriction imposed on the functions exerted by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42. The second restricted state is a state in which the air conditioning device 1 operates with a second restriction imposed, which is a restriction that partially removes the first restriction imposed on the functions exerted by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42.

[0035] The first restriction is a restriction that disables the output of the illuminance detected by the illuminance sensor 51 to the control unit 7. Disabling the output of the illuminance detected by the illuminance sensor 51 to the control unit 7 includes stopping the operation of the illuminance sensor 51, or the control unit 7 controlling the functions of the air conditioning device 1 while excluding the illuminance output to the control unit 7. Therefore, when the output of the illuminance detected by the illuminance sensor 51 to the control unit 7 is disabled, at least one of the magnitude of the output exerted by the functions of the air conditioning device 1 and the switching between enabling and disabling of the functions of the air conditioning device 1 does not depend on the illuminance detected by the illuminance sensor 51. In this case, as a result, the control unit 7 disables the control that changes the magnitude of the output exerted by the functions of the air conditioning device 1 based on the illuminance, or the control that switches at least one of the functions of the air conditioning device 1 between enabling and disabling based on the illuminance.

[0036] The first restriction is a restriction that disables control unit 7 from referring to the illuminance detected by illuminance sensor 51 when control unit 7 controls blower unit 31 by referring to the illuminance detected by illuminance sensor 51. Therefore, blower unit 31 to which the first restriction is applied blows an amount of air that does not depend on the illuminance detected by illuminance sensor 51. As a result, control unit 7 disables control that changes the output of blower unit 31 based on the illuminance.

[0037] The first limit is a limit that sets the upper limit of the amount of air blown by blower 31 to a first upper limit. The first upper limit is smaller than a second upper limit, which is the upper limit of the amount of air blown by blower 31 when the first limit is not imposed on blower 31. Therefore, the maximum volume generated by blower 31 when the first limit is imposed is smaller than the maximum volume generated by blower 31 when the first limit is not imposed. Therefore, the first limit state is more useful than the normal state and the second limit state when sound is undesirable, for example, when the user is sleeping.

[0038] The first and second limits are limits on the output exerted by the alarm unit 41. The output exerted by the alarm unit 41 is, for example, the brightness of the lamp 411 or the volume of the sound emitted by the speaker 412. Therefore, in a situation where the first and second limits are imposed on the functions of the air conditioning device 1, the maximum amount of light or maximum volume emitted by the alarm unit 41 is limited compared to a situation where no limit is imposed on the alarm unit 41. As a result, the maximum amount of light or maximum volume emitted by the alarm unit 41 can be limited in accordance with the conditions of the environment in which the air conditioning device 1 is installed.

[0039] The first and second limits are limits that cause lamp 411 to emit light at a second luminance that is lower than the first luminance. Therefore, in a situation where the first and second limits are imposed on the functions of the air conditioning device 1, lamp 411 lights up at a luminance that is lower than when no restrictions are imposed. As a result, lamp 411 can light up at a luminance that is lower than when the ambient luminance is high, in accordance with a situation where the ambient luminance of the device main body 2 is low.

[0040] Of the status indicator lamp 41A and the warning lamp 41B, preferably, the brightness at which the warning lamp 41B lights up is the same when the air conditioning device 1 is in the first restricted state, the second restricted state, and the normal state. As described above, the warning lamp 41B notifies that an error has occurred in the air conditioning unit 3. Therefore, when the warning lamp 41B is lit, some kind of error has occurred in the air conditioning unit 3, and the user needs to quickly resolve the error. By making the brightness of the warning lamp 41B the same when the air conditioning device 1 is in the first restricted state, the second restricted state, and the normal state, the user can easily recognize that the warning lamp 41B is issuing a warning, even in an environment with low ambient illumination.

[0041] The first restriction is a restriction that disables the operation of the maintenance unit 42. Therefore, in an air conditioning device 1 in the first restricted state, no sound is generated by the operation of the maintenance unit 42. As a result, this is useful in situations where sound is undesirable, such as when the user is sleeping.

[0042] The control unit 7 has a first restriction unit 71, a first release unit 72, a second release unit 73, and a third release unit 74. The first restriction unit 71 imposes a first restriction on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 when the air conditioning device 1 is operating in a normal state. The first release unit 72 releases at least a portion of the first restriction. The second release unit 73 releases the first restriction. The third release unit 74 releases the second restriction imposed on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42.

[0043] When the illuminance sensor 51 detects illuminance below a first predetermined illuminance while the air conditioning device 1 is operating normally, the first restriction unit 71 imposes a first restriction on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42. The first predetermined illuminance is the illuminance of a constantly dark bar, a constantly dark warehouse, a dark theater, a dark movie theater, or a dark bedroom. In an environment below the first predetermined illuminance, it may be undesirable for the air conditioning unit 3 to exert the maximum output specified in the automatic operation mode. For example, a user is likely to sleep in a dark bedroom. Therefore, it is undesirable for the air conditioning unit 3 to exert the maximum output specified in the automatic operation mode, potentially generating noise that disturbs the user's sleep. By imposing the first restriction on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42, the air conditioning device 1 enters the first restricted state.

[0044] When the illuminance sensor 51 detects illuminance below a first predetermined illuminance for a first predetermined time or longer while the air conditioning device 1 is operating in the first restricted state, the first release unit 72 partially releases the first restriction imposed on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42. The first predetermined time is a time during which it can be determined that the sound emitted by the air conditioning device 1 is not a problem. For example, a situation in which the area around the air conditioning device 1 is dark for a long period of time occurs in an environment such as a bar or a warehouse that is always dark. In a warehouse that is always dark, there is usually no one there or people working there, so the sound emitted by the air conditioning device 1 is not a problem. On the other hand, as mentioned above, in a theater, movie theater, or bedroom, the light or sound emitted by the air conditioning device 1 can be a problem by disrupting the viewing of a play, a movie, or sleep. Furthermore, theaters, movie theaters, and bedrooms are not continuously dark for long periods of time; the light becomes bright after a certain period of time has passed.

[0045] For example, when the air conditioning device 1 is installed in a bedroom, 24 hours is set as the first predetermined time. The reason for setting 24 hours as the first predetermined time is that it is not normally expected that a user will sleep for 24 hours straight, and it will be light at least once within a 24-hour period.

[0046] When the illuminance sensor 51 detects an illuminance below the first predetermined illuminance for a first predetermined time or longer, even if the illuminance around the device main body 2 is below the first predetermined illuminance, the first release unit 72 operates to release at least a portion of the first restriction imposed on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42. Here, when the first release unit 72 releases a portion of the first restriction, a second restriction is imposed on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42. The second restriction is imposed on the functions performed by the notification unit 41 in a situation where, for example, the illuminance around the device main body 2 is low but the sound emitted by the air conditioner 1 is not a problem. By imposing the second restriction on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42, the air conditioner 1 enters the second restricted state. As a result, the control unit 7 identifies that the environment in which the air conditioning device 1 is installed is one in which the noise emitted by the air conditioning device 1 is not a problem, and changes the degree of restriction on the functions it performs depending on the identified situation.

[0047] When the illuminance sensor 51 detects illuminance equal to or greater than a first predetermined illuminance while the air conditioning device 1 is in the first restricted state, the second release unit 73 releases the first restriction imposed on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42. When the illuminance around the device main body 2 is equal to or greater than the first predetermined illuminance, problems rarely occur even if the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 operate at the maximum output specified in the automatic operation mode. Operation of the second release unit 73 places the air conditioning device 1 in a normal state. As a result, the control unit 7 identifies situations in which it does not pose a problem for the functions of the air conditioning device 1 to operate at the maximum output specified in the automatic operation mode, and releases the restriction imposed on the functions of the air conditioning device 1 depending on the situation.

[0048] When the second restriction is imposed on the functions exerted by the notification unit 41, the third release unit 74 releases the second restriction when the illuminance sensor 51 detects an illuminance equal to or greater than a second predetermined illuminance. The second predetermined illuminance is an illuminance at which it can be determined that the light emitted by the air conditioning device 1 does not pose a problem. By operating the third release unit 74, the air conditioning device 1 enters a normal state. As a result, the control unit 7 identifies that the light emitted by the air conditioning device 1 does not pose a problem, and releases the restriction imposed on the functions of the air conditioning device 1 according to the situation. The air conditioning device 1, which has been switched from the second restricted state to the normal state by the third release unit 74, enters the first restricted state when the illuminance sensor 51 detects an illuminance less than the first predetermined illuminance. When the air conditioning device 1 goes from the second restricted state to the normal state and then to the first restricted state, and the illuminance sensor 51 detects an illuminance lower than a first predetermined illuminance for a first predetermined time, the air conditioning device 1 releases at least a part of the first restriction imposed on the functions performed by the air conditioning unit 3, the alarm unit 41, and the maintenance unit 42.

[0049] Preferably, the second predetermined illuminance is equal to or greater than the first predetermined illuminance. Therefore, the third release unit 74 releases the second restriction imposed on the function exerted by the notification unit 41 at the first predetermined illuminance or at an illuminance greater than the first predetermined illuminance. As a result, the condition for releasing the second restriction imposed on the function exerted by the notification unit 41 can be set to suit the environment in which the air conditioning device 1 is installed, whether the condition is the same as that of the second release unit 73 or the surroundings of the device main body 2 are brighter than those of the second release unit 73.

[0050] For example, when used in a warehouse that is always dark, loading operations and the like may result in the brightness becoming the same as the first predetermined illuminance. Once the second restricted state is released, the air conditioning device 1 must wait a first predetermined time after entering the first restricted state before it can return to the second restricted state. However, by setting the second predetermined illuminance to an illuminance greater than the first predetermined illuminance, it becomes more difficult to release the second restricted state compared to when the first predetermined illuminance and the second predetermined illuminance are the same.

[0051] In the air conditioning device 1 described above, when the function disabled mode is set, the first restriction is preferably a restriction that turns off all lamps 411 except for warning lamp 41B. Therefore, in the air conditioning device 1 in the first restricted state, all lamps 411 except for warning lamp 41B are turned off. As a result, the air conditioning device 1 can respond by imposing a restriction that turns off lamps 411 even in situations where it is completely undesirable for lamps 411 to emit light.

[0052] Next, the processing of the air conditioning device 1 will be described with reference to Fig. 1 to Fig. 3. Fig. 3 is a flowchart showing the processing of the air conditioning device 1 according to embodiment 1. The processing of the air conditioning device 1 includes steps S1 to S9.

[0053] In step S1, the control unit 7 determines whether or not the illuminance detected by the illuminance sensor 51 is less than a first predetermined illuminance. If a negative determination is made in step S1 (No), the process returns to step S1.

[0054] On the other hand, if a positive determination (Yes) is made in step S1, the processing proceeds to step S2. In step S2, the first restriction unit 71 imposes a first restriction on the functions exerted by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 so that the air conditioning device 1 is in the first restricted state.

[0055] Next, in step S3, the control unit 7 determines whether the illuminance detected by the illuminance sensor 51 is less than a first predetermined illuminance. If a negative determination (No) is made in step S3, the process proceeds to step S9. In step S9, the second release unit 73 releases the first restriction. Then, the process proceeds to step S8.

[0056] On the other hand, if a positive determination (Yes) is made in step S3, the process proceeds to step S4. In step S4, the control unit 7 determines whether the illuminance sensor 51 has continuously detected an illuminance less than the first predetermined illuminance for a first predetermined time period or more. If a negative determination (No) is made in step S3, the process returns to step S3.

[0057] On the other hand, if an affirmative determination (Yes) is made in step S4, the processing proceeds to step S5. In step S5, the first release unit 72 releases part of the first restriction. Therefore, the air conditioning device 1 enters the second restriction state.

[0058] Next, in step S6, the control unit 7 determines whether the illuminance sensor 51 has detected an illuminance equal to or greater than a second predetermined illuminance including the first predetermined illuminance. If a negative determination (No) is made in step S6, the processing returns to step S6.

[0059] On the other hand, if an affirmative determination (Yes) is made in step S6, the process proceeds to step S7. In step S7, the third release unit 74 releases the second restriction.

[0060] Next, in step S8, the control unit 7 controls the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 so that the air conditioning device 1 returns to the normal state. After this, the processing ends.

[0061] [Embodiment 2] An air conditioning device 1 according to embodiment 2 will be described with reference to Figures 1 and 2. The air conditioning device 1 according to embodiment 2 differs from embodiment 1 mainly in the conditions under which the third release unit 74 operates. Below, the differences between embodiment 2 and embodiment 1 will be mainly described.

[0062] As shown in FIG. 2 , in the second embodiment, when a second restriction is imposed on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42, the third release unit 74 releases the second restriction when the illuminance sensor 51 continuously detects an illuminance equal to or greater than a second predetermined illuminance for a second predetermined time or longer. The second predetermined time is the time during which it can be determined that the light emitted by the air conditioning unit 1 is no longer a problem. For example, in a warehouse that is always dark, the illuminance within the warehouse may be set to be equal to or greater than the second predetermined illuminance only during work hours when work is performed within the warehouse. In such a case, the second predetermined time is the upper limit of the time during which work is expected to be performed within the warehouse. Specifically, when the air conditioning unit 1 is installed in a warehouse that is always dark, the first predetermined time and the second predetermined time are set to one week and four hours, respectively. The first predetermined time and the second predetermined time are set assuming a warehouse in which the dark environment continues for approximately one week.

[0063] The operation of the third release unit 74 places the air conditioning device 1 in a normal state. As a result, the control unit 7 identifies a situation in which the light emitted by the air conditioning device 1 does not pose a problem, and releases the restrictions imposed on the functions of the air conditioning device 1 according to the situation. The air conditioning device 1 that has been switched from the second restricted state to the normal state by the third release unit 74 enters the first restricted state when the illuminance sensor 51 detects an illuminance less than a first predetermined illuminance, as in the first embodiment. The air conditioning device 1 that has switched from the second restricted state to the normal state and then to the first restricted state releases at least part of the first restrictions imposed on the functions exerted by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 when the illuminance sensor 51 continuously detects an illuminance less than the first predetermined illuminance for a first predetermined time.

[0064] Next, the processing of the air conditioning device 1 will be described with reference to Figures 1, 2, and 4. Figure 4 is a flowchart showing the processing of the air conditioning device 1 according to embodiment 2. The processing of the air conditioning device 1 includes steps S11 to S19.

[0065] First, the processes in steps S11 to S15 and step S19 are the same as the processes in steps S1 to S5 and step S9 described above.

[0066] Next, in step S16, the control unit 7 determines whether the illuminance sensor 51 has continuously detected an illuminance equal to or greater than a second predetermined illuminance, including the first predetermined illuminance, for a second predetermined time or longer. If a negative determination (No) is made in step S16, the processing returns to step S16.

[0067] On the other hand, if an affirmative determination (Yes) is made in step S16, the process proceeds to step S17. In step S17, the third release unit 74 releases the second restriction.

[0068] Next, in step S18, the control unit 7 controls the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 so that the air conditioning device 1 returns to the normal state. After this, the processing ends.

[0069] [Embodiment 3] An air conditioner 1 according to embodiment 3 will be described with reference to Fig. 1 and Fig. 5 to Fig. 7. Fig. 5 is a block diagram showing an air conditioner 1 according to embodiment 3. Fig. 6 is a flowchart showing the first stage of processing by the air conditioner 1 according to embodiment 3. Fig. 7 is a flowchart showing the second stage of processing by the air conditioner 1 according to embodiment 3. As shown in Figs. 1 and 5, the air conditioner 1 according to embodiment 3 differs mainly from embodiments 1 and 2 in that it further comprises a human presence sensor 52 and a communication unit 82 (see Fig. 5) that communicates with an information communication terminal 83. Furthermore, as shown in Fig. 5, the control unit 7 further comprises a fourth release unit 75, a fifth release unit 76, and an invalidation unit 77 that operate in response to the operation of the human presence sensor 52 or the communication unit 82. Below, the differences between embodiment 3 and embodiments 1 and 2 will be mainly described.

[0070] As shown in Fig. 1, the human presence sensor 52 is provided on the front cover 21 of the device main body 2. The human presence sensor 52 detects human movement and the presence of a person around the device main body 2. The human presence sensor 52 includes, for example, a sensor that detects heat emitted by a person using infrared rays or the like. As shown in Fig. 5, the human presence sensor 52 outputs the detection result to the control unit 7.

[0071] As shown in FIG. 5 , the control unit 7 has a fourth release unit 75 and a fifth release unit 76. When the second restriction is imposed on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42, the fourth release unit 75 releases the second restriction when the human presence sensor 52 detects the presence of a person around the device main body 2 and then does not detect human movement for a third predetermined time or longer. The third predetermined time is the time during which it is determined that the sound emitted by the air conditioning device 1 becomes problematic. For example, the third predetermined time is the time during which a person sleeps. Specifically, the third predetermined time is, for example, eight hours, which is the typical amount of sleep a person receives.

[0072] The air conditioning device 1 enters the normal state as a result of the fourth release unit 75 operating. Once the air conditioning device 1 is in the normal state, it enters the first restricted state when the ambient illuminance is less than the first illuminance. As a result, the control unit 7 identifies a situation in which the sound emitted by the air conditioning device 1 is undesirable, and changes the degree of restriction placed on the functions of the air conditioning device 1 according to the identified situation. Once the air conditioning device 1 has entered the first restricted state via the normal state from the second restricted state, it releases at least part of the first restriction placed on the functions exercised by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 when the illuminance sensor 51 continuously detects an illuminance less than a first predetermined illuminance for a first predetermined time.

[0073] When the first restriction unit 71 has imposed the first restriction on the functions performed by the air conditioning unit 3, the notification unit 41, and the maintenance unit 42, the fifth release unit 76 releases the first restriction when the human presence sensor 52 detects human movement. When the human presence sensor 52 detects human movement, it is assumed that a user is performing some kind of work around the air conditioning device 1, and at least one of the sound or light emitted by the air conditioning device 1 does not pose a problem. For example, in a dark warehouse where people are moving around, it is assumed that someone is working inside the warehouse, so the sound emitted by the air conditioning device 1 does not pose a problem. Therefore, there is no need to impose the first restriction on the functions possessed by the air conditioning device 1.

[0074] By releasing the first restriction, the air conditioning device 1 enters a state other than the first restricted state. As a result, the control unit 7 identifies a situation in which at least one of the sound and light emitted by the air conditioning device 1 is not a problem, and changes the degree of restriction placed on the functions of the air conditioning device 1 according to the identified situation.

[0075] The communication unit 82 shown in Fig. 5 is wirelessly connected to an information communication terminal 83 (not shown) via an external network (not shown). The external network includes the Internet and a LAN (Local Area Network). The information communication terminal 83 includes, for example, a personal computer, a server device, a mobile communication terminal, and a smart speaker. The mobile communication terminal is, for example, a smartphone or a tablet terminal.

[0076] The information communication terminal 83 stores a program that can save in the information communication terminal 83 a location setting, which is a setting of the location where the device main body 2 (see FIG. 1) is installed. The information communication terminal 83 transmits the location setting to the communication unit 82. The location setting includes whether or not the device main body 2 is in a location where it is necessary to impose a second restriction on the functions of the air conditioning device 1. For example, a location where it is not necessary to impose a second restriction on the functions of the air conditioning device 1 is a bedroom. In a bedroom, only sound is an issue, so the second restriction state, in which the sound generated by the air blowing unit 31 is louder than in the first restriction state, is not preferable. On the other hand, for example, a location where it is necessary to impose a second restriction on the functions of the air conditioning device 1 is a warehouse. In a warehouse, sound is not an issue, so the second restriction state, in which the amount of air blown by the air blowing unit 31 is greater than in the first restriction state, is preferable.

[0077] The communication unit 82 is a communication device, and includes, for example, a network interface controller (NIC) that communicates according to a predetermined communication protocol, such as the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol suite (i.e., the Internet Protocol Suite).

[0078] The control unit 7 controls the communication unit 82. By the control unit 7 controlling the communication unit 82, the communication unit 82 receives from the information communication terminal 83 a location setting that indicates that the air conditioning device 1 is set to a location where it is not necessary to impose a second restriction on the functions of the air conditioning device 1.

[0079] The control unit 7 further has a disabling unit 77. When receiving a location setting indicating that the air conditioning device 1 is installed in a location where it is not necessary to impose the second restriction on the functions of the air conditioning device 1, the disabling unit 77 disables the imposition of the second restriction on the functions of the air conditioning device 1. Therefore, when the air conditioning device 1 is installed in a location where it is not necessary to impose the second restriction on the functions of the air conditioning device 1, the air conditioning device 1 operates in a state other than the second restriction state. As a result, the air conditioning device 1 identifies a situation in which it is not desirable to operate in the second restriction state, and changes the degree of restriction imposed on the functions of the air conditioning device 1 in accordance with the identified situation.

[0080] Next, the processing of the air conditioning device 1 will be described with reference to Fig. 1 and Fig. 5 to Fig. 7. Fig. 6 is a flowchart showing the first stage of the processing of the air conditioning device 1 according to embodiment 3. Fig. 7 is a flowchart showing the second stage of the processing of the air conditioning device 1 according to embodiment 3. The processing of the air conditioning device 1 includes steps S21 to S34.

[0081] First, the processes in steps S21 and S22 are the same as the processes in steps S11 and S12 described above.

[0082] Next, in step S23, the control unit 7 determines whether the human sensor 52 has detected human movement. If an affirmative determination (Yes) is made in step S23, the processing proceeds to step S34. In step S34, the fifth release unit 76 releases the first restriction. Then, the processing proceeds to step S32.

[0083] On the other hand, if a negative determination (No) is made in step S23, the process proceeds to step S24. The process of step S24 is the same as the process of step S13. If a negative determination (No) is made in step S24, the process proceeds to step S33. The process of step S33 is the same as the process of step S19.

[0084] On the other hand, if an affirmative determination (Yes) is made in step S24, the process proceeds to step S25. The process of step S25 is the same as the process of step S14.

[0085] Next, in step S26, the control unit 7 controls the communication unit 82 to receive a location setting from the information communication terminal 83. The location setting received by the communication unit 82 is input to the control unit 7. The control unit 7 determines from the input location setting whether or not the location of the air conditioning device 1 is one in which a second restriction needs to be imposed on the functions of the air conditioning device 1. If a negative determination (No) is made in step S26, the disabling unit 77 disables the imposition of the second restriction on the air conditioning device 1. Therefore, the processing returns to step S23. Note that although it has been described that the control unit 7 receives location information from the communication unit 82, the communication unit 82 may also receive location information in advance. In this case, the location setting received by the communication unit 82 is stored in the memory unit 81 by the control unit 7 controlling the memory unit 81. When performing the processing of step S26, the control unit 7 refers to the location setting stored in the memory unit 81 to determine the location where the air conditioning device 1 is installed.

[0086] On the other hand, if an affirmative determination (Yes) is made in step S26, the process proceeds to step S27. The process of step S27 is the same as the process of step S15.

[0087] Next, in step S28, the control unit 7 determines whether or not the human presence sensor 52 has detected the presence of a person around the device main body 2. If a negative determination (No) is made in step S28, the fifth release unit 76 releases the second restriction imposed on the functions of the air conditioning device 1. Then, the processing proceeds to step S32.

[0088] On the other hand, if a positive determination (Yes) is made in step S28, the processing proceeds to step S29. In step S29, the control unit 7 determines whether the time during which the human presence sensor 52 does not detect human movement continues for a third predetermined time or longer. If a positive determination (Yes) is made in step S29, the fourth release unit 75 releases the second restriction imposed on the functions of the air conditioning device 1. Then, the processing proceeds to step S32.

[0089] On the other hand, if a negative determination (No) is made in step S29, the process proceeds to step S30. The processes of steps S30 and S31 are the same as the processes of steps S16 and S17, respectively. Note that the process of step S30 may be the same as the process of step S6.

[0090] Next, in step S32, the control unit 7 controls the air conditioning unit 3, the notification unit 41, and the maintenance unit 42 so that the air conditioning device 1 returns to the normal state. After this, the processing ends.
