<Operation of dressing room air conditioner>
Next, the operation of the dressing room air conditioner 1 will be described. FIG. 9 shows an example of a combination pattern of the operation mode and the operation of each part.

  In the heater driving shown in FIG. 9, the first PTC heater 3a and the second PTC heater 3b constituting the heater unit 3 are set on or off for each operation mode.

  Here, the setting of “strong” when the heater is turned on is a setting for operating both the first PTC heater 3a and the second PTC heater 3b, and the setting of “weak” when the heater is turned on is the setting for the first PTC heater 3a and the second PTC heater 3b. This is a setting for operating either one of the PTC heaters 3b.

  Further, for the fan air volume shown in FIG. 9, the rotation speed of the fan motor 4a is set so as to be selectable between strong and standard for each operation mode, so that the air volume corresponds to the selected operation mode. It has become.

  Further, the ion generation is set to be selectable from negative ions (negative), sterilization ions (positive / negative), and no (no) ion generation for each operation mode. Note that the types of ions that can be selected (positive, negative, negative, and none) are set differently depending on the operation mode.

  The louver 6 is also set to be fixed and to reciprocate up and down (swing) depending on the operation mode.

  Next, the operation in the heating mode will be described with reference to the drawings. When the heating mode button 35 is pressed by the operation unit 32 shown in FIG. 8, the control unit 31 determines that the heating mode is selected, drives the fan motor 4a, and first executes the preliminary heating mode. The PTC heater 3a and the second PTC heater 3b are driven.

  When the fan motor 4a is driven, the impeller 7 shown in FIG. 6 rotates, so that indoor air is sucked from the suction port 8a of the fan unit 4 through the suction port 21b of the front panel 12 shown in FIG. The fan case 8 causes air to flow to the louver 6.

  When the first PTC heater 3 a and the second PTC heater 3 b are driven and energized, the air blown out from the fan unit 4 is heated, and hot air is blown out from the louver 6. In the preheating mode, the amount of heat generated can be increased by driving both the first PTC heater 3a and the second PTC heater 3b, and the dressing room 51 can be warmed in a short time.

  When a predetermined preliminary heating time has elapsed since the start of the preliminary heating mode, the control unit 31 switches the operation mode to the bathing heating mode. In the bathing heating mode, the control unit 31 continues to drive the fan motor 4a and drives either the first PTC heater 3a or the second PTC heater 3b, in this example, the first PTC heater 3a. To do.

  When only the first PTC heater 3a is driven in the heating mode during bathing, compared to the preheating mode in which both the first PTC heater 3a and the second PTC heater 3b are driven, The calorific value is suppressed, and the temperature of the hot air blown out from the louver 6 is lowered.

  Thereby, after warming the dressing room 51 in the preliminary heating mode, the operation mode is switched to the heating mode during bathing, and the amount of heat generated in the heater unit 3 is suppressed, so that the temperature inside the dressing room 51 is further increased. It can be suppressed. The bathing heating mode is configured to end, for example, after a predetermined time has elapsed.

  As the first PTC heater 3a and the second PTC heater 3b, for example, those having an output of about 600 W are used. In the preheating mode, by energizing both the first PTC heater 3a and the second PTC heater 3b, the heater unit 3 becomes a high output heater of about 1200 W and can warm the dressing room 51 in a short time. .

  However, if the driving of both the first PTC heater 3a and the second PTC heater 3b is continued, the temperature of the dressing room 51 rises too much. Therefore, after warming the inside of the dressing room 51 to a predetermined temperature in the preliminary heating mode, the operation mode is switched to the bathing heating mode.

  In the bathing heating mode, the number of heaters to be energized is one, and in this example, the heater unit 3 becomes a heater of about 600 W. As a result, the amount of heat generated in the heater unit 3 is suppressed, so that the temperature of the warm air blown from the louver 6 is lowered, and further temperature increase in the dressing room 51 is suppressed. Therefore, the dressing room 51 heated in the preliminary heating mode is kept warm. In the preheating mode, it is not always necessary to perform temperature control to keep the temperature in the dressing room 51 constant, and by suppressing the amount of heat generated in the heater unit 3, further temperature rise in the dressing room 51, It is only necessary to suppress both of the temperature drop.

  And in this example, the power consumption in the heater part 3 will be halved, and the heating mode can be executed with low power consumption.

  Here, in this example, the heater unit 3 is composed of a plurality of PTC heaters, and the number of PTC heaters to be driven is switched to control the amount of heat generated in the heater unit 3, but the first PTC heater 3a is controlled. The amount of heat generated in the heater unit 3 can also be controlled by controlling the energization amount to the second PTC heater 3b. Moreover, you may combine control of the rotation speed of the fan motor 4a.

  Further, in this example, the number of PTC heaters is two, but two or more may be used. Further, even during the bathing heating mode, more efficient temperature control is possible by controlling the number of PTC heaters to be driven.

  For example, the dressing room air conditioner 1 is provided with a temperature sensor 40 as a temperature detecting means for detecting the temperature of the dressing room 51 as shown in FIG. 3, and the control unit 31 detects the temperature of the dressing room 51 from the output of the temperature sensor 40. Detect temperature.

  As described above, the controller 31 starts the preliminary heating mode as the heating mode, and then switches the operation mode to the bathing heating mode when a predetermined preliminary heating time has elapsed.

  The controller 31 controls the number of PTC heaters to be driven so that the temperature of the dressing room 51 detected by the temperature sensor 40 maintains a predetermined temperature during execution of the bathing heating mode. For example, when the temperature of the dressing room 51 detected by the temperature sensor 40 is lower than a predetermined set temperature, the number of PTC heaters to be driven is increased, and when the temperature of the dressing room 51 is higher than the predetermined set temperature, the dressing room 51 is driven. Reduce the number of PTC heaters. Thereby, efficient temperature control becomes possible.

  In order to suppress the temperature rise, control is performed to reduce the amount of heat generation by reducing the number of energized heaters. However, intermittent control in which energization and de-energization of the heater is intermittent may be performed.

  Next, another embodiment for switching between the preheating mode and the bathing heating mode in the heating mode will be described. As an example, switching between the preheating mode and the bathing heating mode can be performed in conjunction with the presence or absence of a person.

  For example, as shown in FIG. 2, a bathroom 53 adjacent to the dressing room 51 is provided with a human sensor 54 as a person detection means, and the control unit 31 of the dressing room air conditioner 1 determines whether the bathroom 53 Monitor the entrance of people (bathing people) to

  As described above, the control unit 31 first starts the preliminary heating mode as the heating mode, and when the human sensor 54 detects a person, the control unit 31 determines that there is no person in the dressing room 51 and sets the operation mode to the heating mode while bathing. Switch to mode. In the bathing heating mode, as described above, for example, the temperature is controlled by switching to one of the first PTC heater 3a and the second PTC heater 3b to suppress the amount of heat generated in the heater unit 3, and the dressing room 51 Reduce the temperature rise more than necessary.

  Note that the presence or absence of a person may be determined from the presence or absence of lighting in the bathroom 53. As shown in FIG. 2, the lighting 55 of the bathroom 53 is switched on / off by a lighting switch 56. As shown in FIG. 3, the control unit 31 of the dressing room air conditioner 1 monitors the output of the illumination switch 56 and detects whether the illumination 55 is turned on.

  As described above, the control unit 31 first starts the preliminary heating mode as the heating mode, and then detects that the lighting switch 56 has turned on the lighting 55 of the bathroom 53, the person is in the dressing room 51. The operation mode is switched to the above-described heating mode during bathing, judging that there is no more.

  As described above, switching between the preheating mode and the bathing heating mode is automatically performed by setting a timer, detecting the presence or absence of a person, etc., so that manual mode switching is unnecessary. Therefore, it is possible to surely switch from the preheating mode to the bathing heating mode, and to suppress an unnecessarily high temperature rise in the dressing room 51.

  Furthermore, the heating mode may be controlled by detecting that the bather has left the bathroom 53 and entered the dressing room 51 by means of human detection means such as the human sensor 54 and the lighting switch 56. For example, a bather moves from the bathroom 53 to the dressing room 51 by detecting that the person 54 is removed from the human sensor 54 provided in the bathroom 53 or when the lighting switch 56 of the bathroom 53 is turned off. If it is determined, it may be possible to prevent the chill from being felt by stopping the heating mode so that the wet body is not exposed to wind.

  Also, a radiation unit such as a carbon lamp heater or a halogen heater is provided, and as described above, when it is determined by the human detection means that the bather has moved from the bathroom 53 to the dressing room 51, control is performed to switch to radiation heating. May be.

  Now, when the heating mode button 35 and the ion mode interlock button 38 are pushed by the operation part 32 shown in FIG. 8, in addition to control of the heating mode mentioned above, the control part 31 drives the ion generator 5, for example, Generate negative ions. As a result, negative ions are released into the fan case 8, and warm air containing negative ions is blown out from the louver 6 by the air flow by the fan unit 4.

  Therefore, by linking the heating mode and the negative ion generation mode, the temperature in the dressing room 51 rises to a comfortable temperature, and a relaxing effect can be obtained. In the negative ion generation mode, only negative ions may be generated, or more negative ions may be generated than positive ions.

  Next, the operation in the cool breeze mode will be described. When the cool breeze mode button 34 is pressed on the operation unit 32 shown in FIG. 8, the control unit 31 determines that the cool breeze mode is selected, and drives the fan motor 4a and the louver motor 10d. When the fan motor 4a is driven, the impeller 7 rotates, so that indoor air is sucked from the suction port 8a of the fan unit 4 through the suction port 21b of the front panel 12, and the fan case 8 moves the louver 6 to the louver 6. Air flows.

  When the louver motor 10d is driven, the air outlet 10b shown in FIG. 7 reciprocates in the vertical direction. Thereby, ventilation is blown out from the louver 6 to the whole dressing room 51.

  In the cool breeze mode, the first PTC heater 3a and the second PTC heater 3b are not energized, so that the air blown out from the fan unit 4 is not heated, and the air blown out from the louver 6 according to the room temperature. Is done. Therefore, in the cool breeze mode, the dressing room air conditioner 1 can be used as a fan in summer and the like.

  When the cool breeze mode button 34 and the ion mode interlock button 38 are pressed by the operation unit 32 shown in FIG. 8, the control unit 31 drives the ion generator 5 in addition to the above-described cool breeze mode control, for example, negative ions. Is generated. Thus, negative ions are released into the fan case 8, and air containing negative ions is blown out from the louver 6 by the air flow by the fan unit 4.

  Therefore, a relaxation effect by negative ions can be obtained by linking the cool breeze mode and the negative ion generation mode. The cool breeze mode and the positive / negative ion generation mode may be linked.

  Next, the operation in the ion generation mode will be described. When the ion mode selection button 36 is pressed by the operation unit 32 shown in FIG. 8 and the sterilization ion mode is selected, the control unit 31 drives the fan motor 4a, the louver motor 10d, and the ion generator 5. When the fan motor 4a is driven, the impeller 7 rotates, so that indoor air is sucked from the suction port 8a of the fan unit 4 through the suction port 21b of the front panel 12, and the fan case 8 moves the louver 6 to the louver 6. Air flows. In the sterilization ion mode, the first PTC heater 3a and the second PTC heater 3b are not energized.

  When the louver motor 10d is driven, the air outlet 10b shown in FIG. 7 reciprocates in the vertical direction. When the ion generator 5 is driven, both approximately the same number of positive ions and negative ions are released into the fan case 8 here. FIG. 10 is an explanatory diagram showing the air flow in the ion generation mode. In the sterilization ion mode, positive ions and negative ions are emitted from the louver 6 as shown in FIG. The air including both of these is blown out to the entire dressing room 51.

  Therefore, in the sterilization ion mode, air containing both positive ions and negative ions is blown to the entire room, so that airborne bacteria in the air can be inactivated and generation of mold can be suppressed. Also, in the sterilization ion mode, blowing the air blows down the indoor humidity, which is more effective in preventing mold.

  The louver 6 of this example is configured to manually change the blowing direction of the left and right air, but may be configured to be able to change the wind direction in the left and right direction electrically. And by sending air in the sterilization ion mode up, down, left and right, it is possible to send air containing both positive ions and negative ions in a wider range.

  When the ion mode selection button 36 is pressed by the operation unit 32 shown in FIG. 8 and the negative ion mode is selected, the control unit 31 drives the fan motor 4 a and the ion generator 5. When the fan motor 4a is driven, the impeller 7 rotates, so that indoor air is sucked from the suction port 8a of the fan unit 4 through the suction port 21b of the front panel 12, and the fan case 8 moves the louver 6 to the louver 6. Air flows.

  In the negative ion mode, the first PTC heater 3a and the second PTC heater 3b are not energized. In the negative ion mode, the louver motor 10d is not driven and the air direction is kept constant.

  When the ion generator 5 is driven, negative ions are released into the fan case 8 here. As a result, in the negative ion generation mode, air including negative ions is blown out from the louver 6 in a fixed direction by the air flow by the fan unit 4 as shown in FIG. Therefore, in the negative ion mode, the body is cooled by blowing air in summer and the like, and a relaxing effect by negative ions can be obtained.

  As another operation mode, for example, a dryer mode may be provided. In the dryer mode, the control unit 31 increases the rotational speed of the fan motor 4a, for example, in the negative ion mode, and increases the air volume as compared with the negative ion mode. In addition, the louver 6 is fixed in a fixed direction such that the air blows against a person's head. Further, it may be possible to select between blowing air and warm air. Thereby, hair can be dried in a short time with air or hot air containing negative ions.

  Moreover, in order to warm the inside of the dressing room 51 in a shorter time than the preliminary heating mode, a strong heating mode may be provided. In the strong heating mode, the controller 31 warms the dressing room 51 in a shorter time by increasing the number of rotations of the fan motor 4a and increasing the amount of warm air. And the control which returns to normal heating mode is performed by temperature detection or time.

  As described above, the operation mode illustrated in FIG. 9 is an example and is not limited thereto. For example, in order to reduce the fan air volume in the bathing heating mode, the rotation speed of the fan motor 4a may be set to the third speed obtained by adding “weak” to “strong” and “standard”.
