[0009] An air conditioner according to one aspect of the present disclosure is an air conditioner that conditions indoor air and includes a receiving unit that receives an air conditioning control command to start air conditioning operation or a heating control command to start heating operation, a speaker that outputs audio related to the air conditioner, and a control unit that controls the operating mode of the air conditioner based on the air conditioning control command or the heating control command and also controls the speaker, wherein the control unit determines whether the operating mode is appropriate based on the indoor temperature within a predetermined time after receiving the air conditioning control command or the heating control command, and outputs the audio from the speaker if it determines that the operating mode is inappropriate.

[0010] With this configuration, it is possible to provide an air conditioner with improved convenience.

[0011] For example, the control unit may determine whether the operation mode is appropriate based on an outdoor temperature.

[0012] For example, the control unit may determine whether the driving mode is appropriate based on at least one of a calendar and a weather forecast.

[0013] For example, the receiving unit further receives a notification command that notifies information about the air conditioner, When the notification command is received after the predetermined time has elapsed, the control unit may output the sound from the speaker.

[0014] For example, when the control unit determines that the driving mode is inappropriate, the control unit may output a sound from the speaker prompting the driver to change the driving mode.

[0015] For example, the control unit may terminate the output of the sound prompting the user to change the operation mode when a certain time has elapsed since receiving the cooling control command or the heating control command.

[0016] For example, the home appliance may further include an operating device that transmits the cooling control command and the heating control command.

[0017] For example, the operating device may further include a display unit, and the control unit may display information on the appropriateness of the operation mode on the display unit.

[0018] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0019] (Embodiment 1) Fig. 1 is a schematic diagram of an air conditioner according to a first embodiment of the present disclosure, and Fig. 2 is a block diagram showing the configuration of the air conditioner of Fig. 1.

[0020] 1, the air conditioner 10 has an indoor unit 20 arranged in a room Rin to be air-conditioned, and an outdoor unit 30 arranged in an outdoor Rout. In this embodiment, an air conditioner 10 that performs cooling and heating will be described.

[0021] The user selects the air conditioning operation to be performed by the air conditioner 10. For example, when the user performs a selection operation on the remote controller 70 shown in Fig. 1, the air conditioner 10 performs the air conditioning operation corresponding to that operation.

[0022] As shown in FIG. 2, the indoor unit 20 of the air conditioner 10 includes a receiving unit 21, a speaker 22, and a control unit .

[0023] The receiving unit 21 receives a cooling control command to start a cooling operation or a heating control command to start a heating operation. The receiving unit 21 transmits and receives signals, for example, via wired communication or wireless communication. In this embodiment, the receiving unit 21 receives the cooling control command or the heating control command via wireless communication. The receiving unit 21 may be capable of communicating in accordance with standards such as Wi-Fi (registered trademark), IEEE802.2, IEEE802.3, 3G, or LTE. Alternatively, the receiving unit 21 may communicate via the Internet, an intranet, an extranet, a LAN, ISDN, a VAN, a CATV communication network, a virtual private network, a telephone line network, a mobile communication network, a satellite communication network, infrared rays, or Bluetooth (registered trademark). In this embodiment, the receiving unit 21 receives the cooling control command or the heating control command from the remote controller 70 via wireless communication.

[0024] FIG. 3 is a schematic diagram showing an example of a remote controller 70. As shown in FIG. 3, the remote controller 70 has a plurality of buttons, such as a cooling button 71, a heating button 72, a notification button 73, a temperature button 74, a humidity button 75, and a stop button 76, and a display unit 77. The cooling button 71 is a button for sending a cooling control command. The heating button 72 is a button for sending a heating control command. The notification button 73 is a button for sending a notification command, which will be described later. The temperature button 74 is a button for sending a signal to change the set temperature. The humidity button 75 is a button for sending a signal to change the set humidity. The stop button 76 is a button for sending a signal to stop cooling operation or heating operation. The display unit 77 displays the operation mode, set temperature, set humidity, current time, etc., and is, for example, a liquid crystal display.

[0025] For example, when a user presses the cooling button 71 on the remote controller 70, a cooling control command is transmitted by the remote controller 70. When a user presses the heating button 72 on the remote controller 70, a heating control command is transmitted by the remote controller 70. The remote controller 70 corresponds to an "operating device" that transmits the cooling control command and the heating control command.

[0026] The speaker 22 is controlled by the control unit 23 to output audio related to the air conditioner 10. Specifically, the speaker 22 receives an audio output command from the control unit 23 and outputs the audio. The audio related to the air conditioner is audio that notifies information related to the operation of the air conditioner, such as the operation mode (cooling operation or heating operation), set temperature, indoor temperature, or indoor humidity. In the present embodiment, the speaker 22 outputs audio that prompts the user to change the operation mode.

[0027] The control unit 23 controls the components of the air conditioner 10. The control unit 23 includes, for example, a memory that stores a program and a processing circuit corresponding to a processor such as a CPU (Central Processing Unit). The functions of the control unit 23 may be configured using hardware alone, or may be realized by combining hardware and software. The control unit 23 realizes predetermined functions by reading data and programs stored in the memory and performing various arithmetic processing. In the present embodiment, the control unit 23 controls the operation mode of the air conditioner and also controls the speaker 22 based on a cooling control command or a heating control command.

[0028] The control unit 23 executes cooling operation of the air conditioner 10 based on the reception of a cooling control command by the receiving unit 21, and executes heating operation of the air conditioner 10 based on the reception of a heating control command by the receiving unit 21. The control unit 23 determines whether the operation mode is appropriate based on the indoor temperature within a predetermined time after receiving the cooling control command or the heating control command. If the control unit 23 determines that the operation mode is inappropriate, it outputs a sound from the speaker 22.

[0029] <Audio output flow> Fig. 4 is a flowchart showing the audio output operation of the air conditioner of Fig. 1. Note that the process shown in Fig. 4 is an example, and the present embodiment is not limited to the process shown in Fig. 4.

[0030] The process shown in FIG. 4 starts, for example, when the cooling operation or heating operation is turned on by a user's selection operation on the remote controller 70 shown in FIGS. 1 and 3, i.e., when the receiving unit 21 receives a cooling control command or a heating control command.

[0031] In step S11, the control unit 23 determines whether or not an air conditioning control command has been received by the receiving unit 21. If the control unit 23 determines that an air conditioning control command has been received by the receiving unit 21, the process proceeds to step S12. If the control unit 23 determines that an air conditioning control command has not been received by the receiving unit 21, the process proceeds to step S13.

[0032] In step S12, the control unit 23 determines whether the operation mode is appropriate. In this embodiment, whether the operation mode is appropriate is determined based on the indoor temperature. In step S12, the control unit 23 determines whether the cooling operation is appropriate as the operation mode based on the indoor temperature. The indoor temperature is the air temperature of the room Rin, and the indoor temperature can be acquired, for example, from a thermometer built into the indoor unit 20. Alternatively, temperature information can be acquired via a network from a thermometer placed in the room Rin. The control unit 23 determines whether the operation mode is appropriate based on the acquired temperature information. For example, if the acquired indoor temperature is equal to or lower than a predetermined threshold, the control unit 23 determines that the cooling operation is not appropriate as the operation mode. More specifically, if the indoor temperature is, for example, 25°C or lower, the control unit 23 determines that the cooling operation is not appropriate as the operation mode.

[0033] When the air conditioner 10 receives a cooling control command and is performing cooling operation, if the indoor temperature immediately after the start of cooling operation is 25°C or lower, the control unit 23 determines that cooling operation is an inappropriate operation mode. Immediately after the start of cooling operation means, for example, within 30 seconds after the air conditioner 10 receives the cooling control command. If it is within 30 seconds after receiving the cooling control command, the room temperature has not been sufficiently lowered by the cooling operation, and therefore it is appropriate to determine the appropriateness of the operation mode. For example, if the indoor temperature immediately after the start of cooling operation is 25°C or lower, it may not be necessary to lower the indoor temperature by cooling operation, and therefore the control unit 23 determines that the operation mode is inappropriate.

[0034] If the control unit 23 determines in step S12 that the operation mode is appropriate, the process ends. If the control unit 23 determines in step S12 that the operation mode is inappropriate, the process proceeds to step S13.

[0035] In step S13, the control unit 23 determines whether a predetermined time has elapsed since the cooling control command or the heating control command was received. The predetermined time is, for example, 30 seconds since the cooling control command or the heating control command was received.

[0036] If the control unit 23 determines that the predetermined time has elapsed, the process proceeds to step S14. If the control unit 23 determines that the predetermined time has not elapsed, step S13 is repeated.

[0037] In step S14, the control unit 23 outputs audio from the speaker 22. For example, the control unit 23 outputs information about the appropriateness of the operation mode from the speaker 22 by audio. More specifically, when the air conditioner 10 receives a cooling control command, audio may be output to encourage a change in operation mode, such as "The temperature is low. We recommend changing to heating." Also, for example, when the air conditioner 10 receives a heating control command, audio may be output to encourage a change in operation mode, such as "The temperature is high. We recommend changing to cooling." In addition to the above announcements, a warning sound may be output. Once audio is output in step S14, the processing ends.

[0038] In step S15, control unit 23 determines whether or not a heating control command has been received by receiving unit 21. If control unit 23 determines that a heating control command has been received by receiving unit 21, the process proceeds to step S16. If control unit 23 determines that a heating control command has not been received by receiving unit 21, the process ends.

[0039] In step S16, the control unit 23 determines whether the operation mode is appropriate. In step S16, the control unit 23 determines whether the heating operation is appropriate as the operation mode based on the indoor temperature. The control unit 23 determines whether the operation mode is appropriate based on the indoor temperature, based on the acquired temperature information. For example, if the acquired indoor temperature is equal to or higher than a predetermined threshold, the control unit 23 determines that the heating operation is not appropriate as the operation mode. More specifically, if the indoor temperature is, for example, 20°C or higher, the control unit 23 determines that the operation mode is not appropriate.

[0040] When the air conditioner 10 receives a heating control command and is performing heating operation, if the indoor temperature immediately after the start of heating operation is 20°C or higher, the control unit 23 determines that the operation mode is inappropriate. Immediately after the start of heating operation means, for example, within 30 seconds after the air conditioner 10 receives the heating control command. If it is within 30 seconds after receiving the heating control command, the room temperature has not risen sufficiently due to the heating operation, and so it is appropriate to determine whether the operation mode is appropriate. For example, if the indoor temperature immediately after the start of heating operation is 20°C or higher, it may not be necessary to raise the indoor temperature by heating operation, and so the control unit 23 determines that the operation mode is inappropriate.

[0041] If the control unit 23 determines in step S16 that the operation mode is appropriate, the process ends. If the control unit 23 determines in step S16 that the operation mode is inappropriate, the process proceeds to step S13.

[0042] Note that the process shown in Fig. 4 is an example, and the overall operation is not limited to this. For example, the process shown in Fig. 4 may further include additional steps, or steps may be deleted, integrated, and / or divided.

[0043] The control unit 23 determines whether the operation mode is appropriate, and if it determines that the operation mode is inappropriate, outputs a sound from the speaker 22, thereby letting the user know that the operation mode is inappropriate. This improves user convenience. For example, if the user mistakenly presses the cooling button 71 and the heating button 72 on the remote controller 70, the user is notified by sound of the possibility of an error, allowing the user to recognize that they pressed the wrong button.

[0044] In the above-described embodiment, an example has been described in which a user transmits a cooling control command or a heating control command from the remote controller 70, but the present invention is not limited to this. For example, a cooling control command or a heating control command may be transmitted from an electronic device such as a smartphone or a tablet via a network using an application installed on the electronic device.

[0045] Furthermore, in the above-described embodiment, an example has been described in which the operation mode is determined to be inappropriate when a cooling control command is received and the indoor temperature is 25°C or lower, and when a heating control command is received and the indoor temperature is 20°C or higher, but this is not limiting. The above-described threshold value can be changed depending on the environment or climatic conditions of the location where the air conditioner 10 is installed. Alternatively, for example, the set temperature for cooling operation or heating operation may be used as the threshold value.

[0046] Furthermore, in the above-described embodiment, an example has been described in which the air conditioner 10 performs a cooling operation or a heating operation, but this is not limiting. For example, the air conditioner 10 may perform a dehumidifying operation or a humidifying operation in addition to a cooling operation and a heating operation.

[0047] Furthermore, in the above-described embodiment, an example has been described in which sound is output from the speaker 22 when the operation mode is inappropriate, but the present invention is not limited to this. Information related to the air conditioner 10 may be displayed on the display unit 77 of the remote controller 70. For example, as shown in Fig. 3, a notification urging the user to change the operation mode may be displayed on the display unit 77 of the remote controller 70.

[0048] (Embodiment 2) An air conditioner according to a second embodiment of the present invention will be described. In the second embodiment, differences from the first embodiment will be mainly described. In the second embodiment, the same or equivalent components as those in the first embodiment will be denoted by the same reference numerals. In the second embodiment, descriptions that overlap with those in the first embodiment will be omitted.

[0049] Fig. 5 is a flowchart showing the sound output operation of the air conditioner according to embodiment 2. As shown in Fig. 5, embodiment 2 differs from embodiment 1 in that control unit 23 determines whether the operation mode is appropriate based on the outdoor temperature in addition to the indoor temperature.

[0050] In FIG. 5, steps S21, S24 to S25, and S26 are the same as steps S11, S13 to S14, and S15 in the first embodiment, and therefore their explanation will be omitted.

[0051] In steps S22 to S23, the control unit 23 determines whether the operation mode is appropriate. In steps S22 to S23, the control unit 23 determines whether the cooling operation is appropriate as the operation mode based on the indoor temperature and the outdoor temperature.

[0052] In step S22, the control unit 23 determines whether the indoor temperature is equal to or lower than a predetermined threshold. More specifically, the control unit 23 determines whether the indoor temperature is equal to or lower than 25°C. As in the first embodiment, the indoor temperature can be acquired, for example, from a thermometer built into the indoor unit 20 or a thermometer placed in the room Rin. If the control unit 23 determines that the indoor temperature is equal to or lower than 25°C, the process proceeds to step S23. If the control unit 23 determines that the indoor temperature is not equal to or lower than 25°C, the process ends.

[0053] In step S23, the control unit 23 determines whether the outdoor temperature is equal to or lower than a predetermined threshold. More specifically, the control unit 23 determines whether the outdoor temperature is equal to or lower than 16°C. The outdoor temperature is the air temperature of the outdoor Rout, and can be obtained, for example, from a thermometer installed in the outdoor unit 30. If the control unit 23 determines that the outdoor temperature is equal to or lower than 16°C, the process proceeds to step S24. If the control unit 23 determines that the outdoor temperature is not equal to or lower than 16°C, the process ends.

[0054] In this embodiment, when the air conditioner 10 receives a cooling control command, the control unit 23 determines whether cooling operation is the appropriate operation mode in steps S22 and S23. Specifically, when the air conditioner 10 receives a cooling control command, the control unit 23 determines that cooling operation is an inappropriate operation mode if the indoor temperature is 25° C. or lower and the outdoor temperature is 16° C. or lower. In other words, Yes in step S22 and Yes in step S23 indicates that the control unit 23 has determined that cooling operation is an inappropriate operation mode.

[0055] For example, if the indoor temperature is 25°C or lower and the outdoor temperature is 16°C or lower, it is considered that the air conditioner 10 has received an air conditioning control command due to an erroneous operation by the user. Therefore, when the air conditioner 10 receives an air conditioning control command, the control unit 23 determines that the operation mode is inappropriate if the indoor temperature is 25°C or lower and the outdoor temperature is 16°C or lower.

[0056] In steps S27 to S28, the control unit 23 determines whether the operation mode is appropriate. In steps S27 to S28, the control unit 23 determines whether the heating operation is appropriate as the operation mode based on the indoor temperature and the outdoor temperature.

[0057] In step S27, the control unit 23 determines whether the indoor temperature is equal to or higher than a predetermined threshold. More specifically, the control unit 23 determines whether the indoor temperature is equal to or higher than 20°C. If the control unit 23 determines that the indoor temperature is equal to or higher than 20°C, the process proceeds to step S28. If the control unit 23 determines that the indoor temperature is not equal to or higher than 20°C, the process ends.

[0058] In step S28, the control unit 23 determines whether the outdoor temperature is equal to or higher than a predetermined threshold. More specifically, the control unit 23 determines whether the outdoor temperature is equal to or higher than 30°C. If the control unit 23 determines that the outdoor temperature is equal to or higher than 30°C, the process proceeds to step S24. If the control unit 23 determines that the outdoor temperature is not equal to or higher than 30°C, the process ends.

[0059] In this embodiment, when the air conditioner 10 receives a heating control command, the control unit 23 determines whether heating operation is an appropriate operation mode in steps S25 and S26. Specifically, when the air conditioner 10 receives a heating control command, the control unit 23 determines that heating operation is an inappropriate operation mode if the indoor temperature is 20° C. or higher and the outdoor temperature is 30° C. or higher. In other words, Yes in step S25 and Yes in step S26 indicates that the control unit 23 has determined that heating operation is an inappropriate operation mode.

[0060] For example, if the indoor temperature is 20°C or higher and the outdoor temperature is 30°C or higher, it is considered that the air conditioner 10 has received a heating control command due to an erroneous operation by the user. Therefore, when the air conditioner receives a heating control command, the control unit 23 determines that the operation mode is inappropriate if the indoor temperature is 20°C or higher and the outdoor temperature is 30°C or higher.

[0061] By determining whether the operation mode is appropriate based on the outdoor temperature in addition to the indoor temperature, it is possible to more accurately determine whether cooling or heating operation has been performed erroneously and notify the user, thereby further improving user convenience.

[0062] In the above-described embodiment, the control unit 23 determines whether the operation mode is appropriate based on the outdoor temperature in addition to the indoor temperature, but this is not limiting. For example, the control unit 23 may determine whether the operation mode is appropriate based on at least one of calendar information and weather information in addition to the indoor temperature. The calendar information or weather information can be received from an external server. The calendar information is information related to a calendar, such as the current date, day of the week, or season. The weather information is information related to the weather, such as a weather forecast or weather warnings and advisories.

[0063] For example, when the air conditioner 10 receives a cooling control command, if the indoor temperature is 25° C. or lower and it is winter (for example, from December to February), the control unit 23 can determine that the operation mode is inappropriate.

[0064] Alternatively, the control unit 23 may determine whether an operation mode is appropriate based on meteorological information for the area where the air conditioner 10 is installed. For example, the control unit 23 may determine whether an operation mode is appropriate based on meteorological information such as the temperature or weather of the area where the air conditioner 10 is installed, in addition to the indoor temperature.

[0065] (Embodiment 3) An air conditioner according to embodiment 3 of the present invention will be described. In embodiment 3, differences from embodiment 1 will be mainly described. In embodiment 3, components that are the same as or equivalent to those in embodiment 1 will be denoted by the same reference numerals. In embodiment 3, descriptions that overlap with embodiment 1 will be omitted.

[0066] Fig. 6 is a flowchart showing the audio output operation of the air conditioner according to embodiment 3. As shown in Fig. 6, embodiment 5 differs from embodiment 1 in that receiver 21 receives a notification command and causes control unit 23 to output audio from speaker 22 based on the notification command.

[0067] The notification command is a command for notifying, at the request of the user, notification information related to the air conditioner 10. The notification information is, for example, information related to the operation mode, set temperature, set humidity, or current time of the air conditioner 10. In this embodiment, the control unit 23 can notify the user of the appropriateness of the operation mode as notification information.

[0068] For example, when the user presses the notification button 73 on the remote controller 70 shown in Fig. 3, a notification command is transmitted from the remote controller 70. When the receiving unit 21 receives the notification command, the control unit 23 controls the speaker 22 to notify notification information related to the air conditioner 10 by voice or the like.

[0069] In this embodiment, when the receiving unit 21 receives a notification command a predetermined time (e.g., 30 seconds) after the air conditioner 10 receives a cooling control command or a heating control command, information related to the air conditioner 10 is notified by voice. In this embodiment, the notification information related to the air conditioner 10 is, for example, a notification urging the user to change the operation mode.

[0070] The audio output operation according to the third embodiment will be described with reference to Fig. 6. Note that steps S31 to S34 and S38 to S39 in Fig. 6 are the same as steps S11 to S14 and S15 to S16 in Fig. 4 described in the first embodiment, and therefore description thereof will be omitted.

[0071] After the control unit 23 determines that the operation mode is inappropriate and outputs a sound from the speaker 22, for example, the notification button 73 of the remote controller 70 is pressed and a notification command is received by the receiving unit 21. In step S35, the control unit 23 determines whether the receiving unit 21 has received the notification command.

[0072] If the control unit 23 determines that the receiving unit 21 has not received the notification command, the process ends. If the control unit 23 determines that the receiving unit 21 has received the notification command, the process proceeds to step S36.

[0073] In step S36, the control unit 23 determines whether a certain time has elapsed since the cooling control command or the heating control command was received. The certain time since the cooling control command or the heating control command was received is, for example, 10 minutes since the cooling control command or the heating control command was received. If the control unit 23 determines that the certain time has elapsed, it ends output of the sound prompting the user to change the operation mode. If the control unit 23 determines that the certain time has not elapsed, the process proceeds to step S37.

[0074] In step S37, the control unit 23 outputs audio from the speaker 22. The control unit 23 outputs notification information related to the air conditioner 10 by audio from the speaker 22. The control unit 23 may, for example, output information related to the appropriateness of the operation mode by audio from the speaker 22. More specifically, as in step S14 of FIG. 4, the control unit 23 may output audio encouraging a change in operation mode, such as "The temperature is low. We recommend changing to heating" or "The temperature is high. We recommend changing to cooling." Once the audio is output in step S37, the processing ends.

[0075] In the air conditioner 10, if the control unit 23 determines that the operation mode is inappropriate, it is considered highly likely that the user performed an erroneous operation until a certain time (e.g., 10 minutes) has elapsed since the cooling control command or heating control command was received. On the other hand, if the certain time has elapsed, it is considered that the operation was intended by the user rather than an erroneous operation. For this reason, if a notification command is received within the certain time since the cooling control command or heating control command was received, the control unit 23 outputs a voice from the speaker 22 urging the user to change the operation mode. This configuration notifies the user of the possibility of an erroneous operation, improving convenience.

[0076] In the above-described embodiment, an example has been described in which sound is output from the speaker 22 in response to reception of a notification command, but the present invention is not limited to this. For example, notification information may be displayed on the display unit 77 of the remote controller 70 shown in FIG. 3. [Industrial Applicability]

[0077] The present disclosure is applicable to any air conditioner that can perform cooling operation and heating operation. [Explanation of symbols]
