Description

  The present invention relates to a bathroom air conditioner. Specifically, after drying laundry and dried items such as clothes (hereinafter referred to as laundry) in the bathroom, the laundry after drying is left in the bathroom or the drying time is insufficient. Even in this case, the laundry can be reliably dried by automatically performing the additional drying process (re-drying process).

  A bathroom air conditioner is known as an air conditioner with a drying function (Patent Document 1). When drying such laundry in the bathroom using such a bathroom air conditioner, the laundry is hung on a laundry member such as a laundry pipe installed in the bathroom, and is provided in the operation unit. The drying mode switch is selected, and the drying operation is performed by selecting the drying time with a timer.

  The drying operation is a normal timer operation, and the drying operation ends after a timer time selected in advance (for example, after 4 hours). When the drying operation is completed, the laundry is taken out of the bathroom and stored in a chest.

Japanese Patent Application Laid-Open No. 2004-21959

  By the way, as described above, the drying operation is a normal timer operation, and the drying operation automatically stops when the set timer time is reached. If the timer time is not set sufficiently, for example, if the timer time is set too short in consideration of power saving, the laundry may not be completely dried even after the drying operation is completed. . In other words, it is in a dry state. In such a case, it is necessary to select the drying operation mode again, set the timer time again, and execute the drying operation.

  Moreover, even if the timer setting time is appropriate and the laundry is sufficiently dried, the laundry may be left in the bathroom after the drying operation is completed. For example, when drying operation is performed at midnight or the like. If the laundry or the like is left in the bathroom as it is, moisture in the bathroom will adhere to the dried laundry or the like again, which may cause a problem that the laundry or the like is not sufficiently dried.

  Therefore, the present invention solves such a conventional problem, and automatically dries the operation mode again when the laundry or the like is insufficiently dried.

To solve the problems described above, the bathroom air conditioning system according to the present invention, there is provided a full air conditioning system comprising a conditioning means for performing air conditioning operation in the bathroom, and a humidity detecting means for detecting the humidity in the bathroom, wet A humidity comparison comparing the first humidity detected during the 24-hour ventilation operation before the start of the drying operation and the second humidity detected after a predetermined time has elapsed after the completion of the drying operation by the degree detection means and means, based on the humidity comparing means, when the second humidity is greater than the first humidity perform additional drying operation, when the second humidity is less than the first humidity perform a 24-hour ventilation operation And a control means for controlling to do so.

  In the present invention, a drying operation mode is prepared as one of the air conditioning operation modes. Moreover, in order to detect the humidity in a bathroom, the humidity sensor as a humidity detection means is provided. The humidity sensor can be provided in the air conditioner main body and in the vicinity of the inlet for sucking air in the bathroom. The sensor output of the humidity sensor is supplied to a control / arithmetic unit that controls the air conditioning operation.

The control / arithmetic unit is associated with an operation unit for selecting various operation modes.
Therefore, the function of this control / calculation unit includes a function of comparing the humidity detected as a part thereof and controlling the air conditioning operation mode based on the result.

The bathroom air conditioner is provided with a 24-hour ventilation operation mode. When the 24-hour ventilation operation mode is selected, the humidity in the bathroom is periodically detected. When drying operation mode for drying the laundry or the like is selected, the drying operation mode is detected just before a selected humidity or drying operation mode is detected immediately after the selected humidity first humidity Save as. As for the first humidity, it is possible to sample the humidity periodically (for example, every 30 minutes) and use the average value as the first humidity in the normal operation of the 24-hour ventilation operation mode. In that case, the average value of the humidity sampled immediately before the timing when the drying operation mode is selected can be used. In the 24-hour ventilation operation mode, the first humidity (average value) is about 50%.

Next, the humidity in the bathroom is detected after a lapse of a predetermined time from the end of the drying operation mode. The predetermined time is about 30 minutes to 1 hour. This is because if the predetermined time is too short, indoor humidity (15 to 30%) in the dry operation mode may be detected. This detected humidity is set as the second humidity and compared with the first humidity.

  When the humidity is higher than before (including immediately after) the drying operation, the humidity in the bathroom is higher. In this case, the laundry is not sufficiently dry. Judgment is made and additional drying operation is performed. The operation time for the additional drying operation varies depending on the humidity difference. If the relationship between the operation time of the additional drying operation and the humidity difference is mapped in advance, the additional drying operation time and the operation target suitable for the humidity difference can be easily selected from the humidity difference.

  In the additional drying operation, if the air temperature is constant and the heater temperature (heater calorific value) and operation time can be varied according to the humidity difference, the heater temperature is constant and the air flow and operation time according to the humidity difference. Alternatively, both of them (air volume and heater temperature operation time) may be made variable according to the humidity difference. Furthermore, the circulation ventilation operation may be performed without energizing the heater. The humidity may be continuously monitored after the first additional drying, and the second and subsequent additional drying may be performed. This is for reliably drying the laundry.

  In the present invention, when the humidity after the completion of the drying operation is higher than the humidity immediately before the drying operation, the additional drying operation is automatically performed. Thereby, even when the laundry or the like is left in the bathroom or when the drying operation time is set to be short, the laundry or the like can be reliably dried.

  Next, a preferred embodiment of a bathroom air conditioner according to the present invention will be described in detail with reference to the drawings.

  FIG. 6 is a block diagram illustrating an example of a control function unit of the bathroom air conditioner 1. In the control function unit of the bathroom air conditioner 1, an operation unit (remote control operation unit) 25 and a humidity sensor 26 for humidity detection are connected to a control / calculation unit 24 including a CPU (Central Processing Unit) and a memory. The The control / arithmetic unit 24 is further connected to a circulation fan fan 53a, a ventilation fan motor 59a, a heater 58, and the like. The operation unit 25 is, for example, a remote control device independent of the bathroom air conditioner 1 main body, and is attached to the wall surface of the washroom 17 as shown in FIG.

  FIG. 7 is a configuration diagram illustrating an example of the operation unit 25. The operation unit 25 includes a display unit 39 such as an LCD and various operation buttons. As operation buttons, for example, a power button 38 for turning on / off the bathroom air conditioner 1, a heating mode button 28 for selecting a heating operation mode, a cool air mode button 29 for selecting a cool air operation mode, and a ventilation operation mode are provided. A ventilation mode button 30 to be selected and a drying mode button 31 to select a drying operation mode are provided.

  The drying operation mode is an operation mode used when drying laundry in the bathroom, and in the present invention, an additional operation mode in consideration of the humidity in the bathroom 18 is set in relation to the drying operation mode. Has been.

  In order to allow the user to check the selected operation mode, for example, a lamp 32 is provided corresponding to each button, and the lamp 32 corresponding to the button of the selected operation mode is turned on. The operation mode is executed only for the time set by the timer button 33 (timer time).

  Further, a drying operation mode end button 34 is provided. Even within the operation time set by the end button 34, the drying operation mode can be forcibly ended.

  As described above, the bathroom air conditioner 1 is provided with a plurality of operation modes, and any one of them can be selected. The heating operation mode will be described.

(1) Heating Operation Mode When the heating operation mode button 28 is pressed, the circulation fan motor 53a and the PTC heater 58 are driven based on a control signal from the control / calculation unit 24. When the circulation fan motor 53a is driven, indoor air is sucked from the suction port 57a of the circulation fan part 53 through the suction port 6b of the front panel 6, and the air flows to the outlet 57b by the circulation fan case 56.

  At the same time, the PTC heater 58 is energized. As the PTC heater 58 is heated, the air passing through the air passage 56 a is heated, and hot air is blown out from the air outlet 7 of the front panel 69. Thereby, in the heating mode, the bathroom 102 can be warmed in winter or the like.

  In the heating mode, the ventilation fan motor 59a is not driven, so that ventilation is not performed. Therefore, the air in the bathroom 18 heated in the heating mode is not discharged to the outside.

(2) Cool Wind Operation Mode When the cool wind mode button 29 is pressed, the circulation fan motor 53a is driven by a control signal from the control / calculation unit 24. When the circulation fan motor 53a is driven, indoor air is sucked from the suction port 57a of the circulation fan unit 53 through the suction port 6b of the front panel 6, and air flows to the outlet 57b by the circulation fan case 56.

  In the cool breeze mode, the PTC heater 58 is not energized. Therefore, the air passing through the air passage 56a is not heated, and the air corresponding to the room temperature is blown out from the air outlet 6a. Thereby, in the cool breeze operation mode, the bathroom air conditioner 1 can be used as a fan in summer or the like. In the cool air mode, the ventilation fan motor 59a is driven, ventilation is performed, and a circulation ventilation operation is performed.

(3a) Ventilation operation mode When the ventilation mode button 30 is pressed, the ventilation fan motor 59a is driven by a control signal from the control / calculation unit 24. When the ventilation fan motor 59a is driven, the air in the bathroom 18 is sucked from the suction port 6b, and the air in the bathroom 18 passes outside through the second ventilation air passage 66b and the suction port 62a of the ventilation fan unit 59. The air is exhausted (shown by the chain line in FIG. 4).

  Further, when the impeller 60 shown in FIG. 11 rotates, the air from the outside of the bathroom 18 shown in FIG. 1 is sucked through the first ventilation air passage 66a and the suction port 62a of the ventilation fan unit 59, and then exhausted. (FIG. 4 shows a chain line).

(3b) 24-hour ventilation mode When the 24-hour ventilation mode button 30a is pressed, the ventilation fan motor 59a is activated by a control signal from the control / calculation unit 24. When the ventilation fan motor 59a is driven, the air in the bathroom 18 is sucked from the intake port 6b, and the air in the bathroom 18 is exhausted to the outside through the second ventilation air passage 66b and the suction port 62a of the ventilation fan unit 59. (FIG. 4 shows a chain line).

  Further, when the impeller 60 shown in FIG. 11 rotates, the air from the outside of the bathroom 18 shown in FIG. 1 is sucked through the first ventilation air passage 66a and the suction port 62a of the ventilation fan unit 59, and then exhausted. (FIG. 4 shows a chain line).

  The 24-hour ventilation mode is normally selected, and the fan motor is continuously or intermittently set so that the ventilation of a predetermined area such as the entire house satisfies a predetermined ventilation frequency (for example, 0.5 times / hour). 59a is driven, and air in other rooms such as a living room is sucked in through the air inlet 23a of the bathroom door 23a of the bathroom 18 so that ventilation is always performed.

(4a) Drying Operation Mode When the drying mode button 31 is pressed, the circulation fan motor 53a, the ventilation fan motor 59a, and the PTC heater 58 are driven by a control signal from the control / calculation unit 24.

  When the circulation fan motor 53a is driven, indoor air is sucked from the suction port 57a of the circulation fan unit 53 through the suction port 6b, and the air flows to the outlet 57b by the circulation fan case 56. When the PTC heater 58 is driven and energized, the air passing through the air passage 56a is heated and hot air is blown out from the air outlet 6a of the front panel 6.

  When the ventilation fan motor 59a is driven, the impeller 60 rotates, so that the air in the bathroom 18 is sucked from the suction port 6b, and the sucked air passes through the second ventilation air passage 66b and the ventilation fan unit 59. The air is exhausted outdoors through the suction port 62a.

  Thus, in the drying mode, by blowing warm air into the bathroom 18, the laundry such as the laundry suspended on the laundry pipe 22 can be dried.

(4b) Additional Drying Operation Mode When the drying operation mode is selected, the control / calculation unit 24 described above monitors the sensor output from the humidity sensor 26 and determines the humidity (first humidity) under the first predetermined condition. ) And the humidity under the second predetermined condition (second humidity), the presence or absence of the humidity difference is detected, and if there is a humidity difference, additional drying operation is performed according to the humidity difference .

  Here, the first predetermined condition is immediately before or immediately after the drying operation mode, and the second predetermined condition is when a predetermined time has elapsed after the drying operation mode is finished.

  In this example, when the drying operation mode for drying laundry is selected, the humidity detected immediately before the drying operation mode is selected or the humidity detected immediately after the drying operation mode is selected Store as 1 humidity. As for the first humidity, it is possible to sample the humidity periodically (for example, every 30 minutes) and use the average value as the first humidity during the 24-hour ventilation operation mode that is normally operated. In that case, the average value of the humidity sampled immediately before the timing when the drying operation mode is selected is used as the first humidity. In the 24-hour ventilation operation mode, the first humidity (average value) is about 50%.

  Next, the humidity in the bathroom is detected after a predetermined time has elapsed since the drying operation mode ended (corresponding to a second predetermined condition). The predetermined time is about 30 minutes to 1 hour. This is because if the predetermined time is too short, indoor humidity (15 to 30%) in the dry operation mode may be detected. This detected humidity is set as the second humidity and compared with the first humidity.

  When the humidity is higher than before (including immediately after) the drying operation, the humidity in the bathroom is higher. In this case, the laundry is not sufficiently dry. Judgment is made and additional drying operation is performed. The operation time for the additional drying operation varies depending on the humidity difference.

  In the additional drying operation, if the air temperature is constant and the heater temperature (heater calorific value) and operation time can be varied according to the humidity difference, the heater temperature is constant and the air flow and operation time according to the humidity difference. Alternatively, both of them (air volume and heater temperature operation time) may be varied according to the humidity difference. Further, the circulation ventilation operation in which the heater 58 is driven by the circulation fan motor 53a and the ventilation fan motor 59a similar to the energized cool wind operation mode may be used.

  If the relationship between the operation time of the additional drying operation and the humidity difference is tabulated in advance, the additional drying operation time and the operation target suitable for the humidity difference can be easily selected from the detected humidity difference.

  One example is shown in the following (Table 1). The additional drying operation mode of the humidity comparison data table shown in (Table 1) is a case where both the air volume and the heater heat generation amount are varied. This humidity comparison data table is stored in the humidity comparison data table storage unit 39 shown in FIG.

湿度差が少ないときは、追加乾燥時間は短く設定され、湿度差が大きくなるにつれて追加乾燥時間が長くなるように設定されている。湿度差が大きいときはそれだけ湿気が洗濯物等に付着していると考えられるからである。ただし、（表１）に示した追加乾燥時間の例は、あくまでも一例にすぎない。

When the humidity difference is small, the additional drying time is set short, and the additional drying time is set longer as the humidity difference becomes larger. This is because when the humidity difference is large, it is considered that moisture adheres to the laundry. However, the example of the additional drying time shown in (Table 1) is only an example.

  The humidity may be continuously monitored after the first additional drying, and the second and subsequent additional drying may be performed. This is for reliably drying the laundry. In that case, the end of the additional drying operation can be selected from the following.

(1) When the drying operation end button 34 provided on the remote control operation unit 25 is selected, the operation is forcibly ended even before the additional drying time has elapsed. This is to respect the intention of the user.

(2) The additional drying operation is forcibly terminated after a predetermined number of times. For example, if it is repeated three times, it is forcibly terminated.

(3) When the humidity difference is large, the additional drying operation is repeated, but forcibly terminated at the set time by the timer. For example, it is forcibly terminated after 8 hours. In this case, the upper limit time of the additional drying operation is preset by the timer in advance.

  The dry operation mode can be used in combination with the 24-hour ventilation operation mode. In this case, fresh outside air is taken in from an air intake provided in a predetermined room. And the predetermined ventilation frequency | count can be satisfy | filled by setting the air volume of the ventilation fan part 59 so that required ventilation air volume may be obtained. The air volume can be set to the standard air volume of the ventilation fan unit 59 that satisfies the predetermined ventilation frequency.

  Next, an example of processing in the drying operation mode with the additional drying operation function described above will be described with reference to the flowchart of FIG. This example is a processing example when the dry operation mode is selected when the 24-hour ventilation operation mode is operating.

  The processing program shown in FIG. 8 is activated when the drying operation mode is selected. However, when the 24-hour ventilation operation mode is selected, the sensor output (humidity information) from the humidity sensor 26 is periodically assumed as a precondition. It is assumed that the average value of the sampled humidity information is stored as the first humidity information in a memory (or an external memory) in the control / calculation unit 24. In the case where the 24-hour ventilation operation mode is off and only the drying operation mode is selected, the sensor output immediately after the drying operation mode is selected is read and the humidity information is stored as the first humidity information. Shall be. Therefore, FIG. 8 is an example of the former.

  In the state where the 24-hour ventilation operation mode is operating, the intake air humidity is periodically sampled (step 81). In this state, the drying mode button 31 is operated to select the drying operation mode, and the drying operation time is selected by the timer button 33 to set the drying operation time (step 82).

  As a result, the drying operation is started, and the intake air humidity sampled and averaged in advance is stored as the first humidity (step 83). By performing the additional drying operation, the humidity in the bathroom 18 gradually decreases (decreases). Due to this decrease in humidity, the laundry and the like are gradually dried.

  During the additional drying operation, the set drying operation time is monitored, and when the drying operation time arrives, the drying operation ends (step 84). When the drying operation is completed, the mode shifts to the 24-hour ventilation operation mode, and the intake air humidity is detected when a predetermined time (first predetermined time, approximately 30 minutes to 1 hour) after the drying operation has elapsed. Then, the detected air humidity is stored in the memory described above as the second humidity (step 85).

  Subsequently, the humidity difference between the first humidity and the second humidity is compared (step 86). When the second humidity is lower than the first humidity, the end of the drying operation mode is maintained as it is for 24 hours. The ventilation operation mode is continued (step 87). When the current humidity in the bathroom 18 is lower than the humidity at the start of the drying operation, the humidity in the bathroom 18 is less likely to adhere to laundry such as laundry, so washing even if the drying operation mode is terminated as it is. It is thought that the dry state of things etc. is maintained as it is.

  On the other hand, when the second humidity is higher (higher) than the first humidity, it is determined that the internal humidity of the bathroom 18 has increased, and the laundry is considered to be in a dry state. . In that case, with reference to the humidity comparison data table shown in (Table 1), the additional drying operation time and the operation target are designated, and a transition is made to the additional drying operation mode (step 88).

  Then, after the first drying operation, when the second predetermined time including the additional drying operation time has elapsed or when the drying end button 34 is pressed, the additional drying operation mode is terminated ( Step 89).

  Here, the second predetermined time in step 89 includes the following cases.

(1) When the number of additional drying processes is set to 1, it indicates the additional drying operation time when referring to the table. In this case, the process does not transition to step 90.

(2) When the number of additional drying processes is set to a plurality of times, it indicates the last additional drying operation time. In this case, when transitioning to the next additional drying operation mode, the second humidity is detected in step 90 after waiting for a first predetermined time after completion of the additional drying. Then, the humidity difference is compared based on the newly detected second humidity (step 86). That is, the second humidity is updated every additional drying process, and the additional drying time is newly set with reference to the humidity comparison data table.

(3) When the number of additional drying processes is not set and an upper limit time (for example, 8 hours) of additional drying operation by a timer is set, this upper limit time is indicated. Accordingly, even in this case, the process proceeds to step 90, where the second humidity is updated, and the additional drying time is reset.

  By performing the above processing, the laundry can be kept dry even when the laundry is left in the bathroom 18.

  In the bathroom air conditioner 1 described above, the circulation fan and the ventilation fan are provided independently. However, the circulation fan and the ventilation fan are configured as a single fan, and the circulation air path is provided by a damper that is an air path switching unit. The ventilation air passage may be switched, or air may be blown to both air passages, and is not limited to the bathroom air conditioner described in the embodiments.
