Description

  The present invention includes a heat source that forcibly changes the ambient temperature, and is used with an air conditioner that adjusts the temperature of the target space by operating the circulator to reduce temperature unevenness in the target space during heating or cooling. About. The circulator in the present invention is not limited to a device specialized in the function of stirring room air, but may be a fan, a fan, a ceiling fan, an air as long as the device includes at least a fan and a control unit that controls the operation of the fan. Any device capable of exhibiting a function of stirring room air is included, such as a purifier, a humidifier, a dehumidifier, a fan heater that operates only a fan, and an air conditioner set to blow.

  When the room is heated or cooled, warm air accumulates above the room, while cold air accumulates below the floor. To improve this, propeller fan type and sirocco fan type circulators are used.

  When operating the circulator, use a manual switch or remote control switch. This operation is performed simultaneously with the operation of the heater or the air conditioner, or is performed manually from the point of time when the room temperature rises or falls and a temperature difference appears between above and below the room.

  As an example of a circulator aiming at an energy saving effect by performing intermittent operation according to room temperature instead of continuous operation as well as solving the trouble of manual operation described above, for example, according to the circulator described in Patent Document 1 For example, if a single temperature sensor is placed in the circulator body and the circulator is wall-mounted in winter and the room temperature rises by heating the room, the temperature reaches the preset temperature. The circulator motor that had been stopped until then starts operation, and in summer, the circulator is placed on the floor, the mode switch is switched, and the room temperature near the floor is lowered by cooling. When the temperature of the circulator motor has been stopped and the temperature has risen. It has also been proposed such to stop the operation of the motor at its set temperature. Also, for example, according to the circulator described in Patent Document 2, the temperature near the ceiling and the floor is measured using a temperature sensor such as an infrared sensor, and based on the temperature at the upper and lower two points or the temperature difference between them. The circulator is started and the wind speed or air volume is controlled. In addition to the above, various circulators with various contrivances have been proposed.

On the other hand, in air conditioners that previously required the assistance of circulators, research and development related to further improvement of comfort has been actively conducted in recent years, and temperature unevenness in the target space has not been assumed in the past. Various air conditioners that are distributed have begun to be proposed. For example, according to the air conditioner shown in Patent Document 3, a person's position is detected by a human body detection sensor by distinguishing it in the left and right direction and the distance, and the air flow direction of the conditioned air is changed depending on the detection result. Has been. Further, for example, according to the air conditioner described in Patent Document 4, the temperature unevenness of the target space is greatly improved as compared with the prior art by devising the blowing of conditioned air. In addition, during heating, conventionally, warm air has accumulated in the upper part of the room, and cold air has accumulated in the lower part near the floor.For example, according to the air conditioner described in Patent Document 5, Warm air reaches below the indoor floor and is controlled to have a temperature distribution different from the temperature distribution previously considered.

  As shown above, various improvements have been made even in air conditioners that previously required the assistance of a circulator, resulting in a temperature distribution that is significantly different from the room temperature distribution assumed on the conventional circulator side. Is becoming mainstream. However, in recent years, further energy saving of equipment has been screamed, especially in air conditioners, which consumes a large amount of power and demands efficient operation as much as possible. In some cases, higher efficiency operation is desired and a circulator is used in combination.

  Furthermore, in recent years, the size of living rooms has been increasing due to changes in housing conditions. In addition, a rectangular shape (rectangular or square) has been generally used for the shape of the room, but in recent years, an L-shape or a so-called vertically or horizontally long room in which the dimensions in the vertical and horizontal directions are greatly different, or Various rooms with irregular shapes, such as very high ceilings, are emerging. In such a large room or an irregularly shaped room, not only a conventional air conditioner but also an air conditioner to which the above-described improvements are added needs the assistance of a circulator. However, in this case, since the room is large or has an irregular shape, the conventional circulator can be used not only in the air conditioner to which the above-mentioned improvements are added, but also in the case of using the conventional air conditioner. The temperature distribution is very different from the room temperature distribution assumed on the side.

  In other words, in the target space that has a temperature distribution that cannot be assumed in the past, the temperature of the air in the target space as in the past or the temperature near the ceiling and the floor is detected, and the circulator is controlled only depending on it. However, there is a new problem that the vehicle cannot be operated efficiently.

  In view of the above situation, the present invention controls the circulator based on a completely different idea from the conventional technical idea, and thus it can be applied to the shape of an air conditioner or room that has a temperature distribution that cannot be assumed conventionally. Accordingly, an object of the present invention is to provide a circulator capable of obtaining an energy saving effect and a control method thereof.

  In order to achieve the above object, the present invention provides a heat source that forcibly changes the ambient temperature, detects the start of operation of an air conditioner that adjusts the temperature of the target space by its operation, and detects temperature unevenness in the target space.

  It is known that when the air conditioner is operated in a room where a certain degree of airtightness is maintained, the humidity of the air in the room fluctuates rapidly. For example, when the cooling operation is started, the room temperature rapidly decreases. However, the absolute humidity of the room does not vary greatly. Therefore, the relative humidity of the room is greatly increased. For example, when the heating operation is started, the temperature of the room rapidly increases. However, the absolute humidity of the room does not vary greatly. Therefore, the relative humidity of the room is greatly reduced. Even if the air conditioner has been improved so that the temperature unevenness as described above is greatly relieved, or when the shape of the room is large or irregular, This is a phenomenon that can be said when the airtightness of the room is maintained to some extent.

  Further, according to the present invention, in the circulator having the above-described configuration, when a decrease in humidity of a preset width occurs during a preset time, the position where the circulator is installed is used as a reference from above to below the target space. The fan is driven to generate an air flow.

When both of these occur, the control unit starts the operation of the fan.

  Changes in the humidity of the room are also assumed when the air conditioner is not started. For example, when the weather changes suddenly. According to this configuration, since the operation of the circulator is started by obtaining both humidity and temperature information, for example, when the humidity of the environment suddenly increases due to the approach of the warm front, and the operation of the air conditioner A distinction is made when the is started.

A temperature sensor that detects a temperature and / or a temperature difference between two points, a point including an indoor ceiling or near the ceiling, and a point including an indoor floor or near the floor surface. The temperature difference is greater than or equal to a preset temperature difference, and the control unit starts operating the fan by comparing the humidity of the room with the preset humidity.

  According to this configuration, it is sensed that there is a large difference between the room ceiling or near-ceiling temperature and the floor or near-floor temperature, and the room relative humidity is lower than the preset relative humidity. Or that the room has a large difference in the ceiling and floor temperatures, and that the room relative humidity is higher than the preset relative humidity. In this case, since the control unit starts the operation of the fan, the temperature of the room or the vicinity of the ceiling and the vicinity of the floor or the floor surface when the cooling operation is started or the heating operation is started.

According to this configuration, the means for determining the time determines whether the time is summer or winter, and the circulator is operated when the relative humidity of the room reaches a relative humidity set in advance according to the season. For example, in the summer season, the circulator is operated when the relative humidity of the room rises above a preset relative humidity (for example, 90%). For example, in the winter season, the relative humidity (for example, 15%) or less is set. If the relative humidity of the room decreases, the circulator is operated. The relative humidity set in advance is determined from past weather data for each region where the circulator is used, and a suitable value is appropriately adopted.

  The present invention also includes a fan that causes an air flow in the target space, and a control unit that controls the operation of the fan, and a circulator for reducing temperature unevenness in the target space. A humidity sensor that detects both of the relative humidity and a means for determining the current time, further comprising: judging from the absolute humidity, the relative humidity, and the current time, and the controller starts operating the fan. It is characterized by. According to this configuration, the means for determining the time determines whether the time is summer or winter, the temperature is calculated from the absolute humidity and relative humidity of the room, and the operation of the circulator is calculated from the season, time zone, and calculated temperature. The necessity is judged, and the circulator is operated when necessary. For example, when the absolute humidity is 12 g / kg and the relative humidity is 40% during the summer day, the room temperature is calculated to be 32.2 ° C. As a result, it is determined that the air conditioner is not operating and the circulator is operated. Is not done. For example, when the absolute humidity is 12 g / kg and the relative humidity is 90% during the summer day, the room temperature is calculated as 18.5 ° C. As a result, it is determined that the air conditioner is operating and the circulator is operated. Is done. For example, when the absolute humidity is 5 g / kg and the relative humidity is 60% during the daytime in winter, the room temperature is calculated as 11.4 ° C.

When a large change in humidity is detected, the operation of the circulator is started. As a result, when a temperature distribution that cannot be assumed in the past is generated, for example, when the air conditioner is improved so that the above-described temperature unevenness is greatly reduced, or the shape of the room Even if it is large or has an irregular shape, the operation of the air conditioner can be detected reliably, and the circulator can be started properly, thus ensuring an energy saving effect. be able to.

  It should be noted that the diffusion of humidity is very fast compared to the diffusion of temperature, so even if large temperature irregularities are formed in the room, the humidity will spread over it, so the start of circulator operation should be judged by humidity. This makes it possible to start the circulator more quickly and appropriately than when judging the start of the circulator based only on the temperature. In addition, since it is possible to suppress the occurrence of problems such as the operation not starting easily even though the circulator is required to operate, an energy saving effect can be obtained with certainty.

  Further, according to the present invention, when a decrease in humidity of a preset width occurs during a preset time, that is, when the heating operation of the air conditioner is started, a significant decrease in humidity is detected. The fan is driven so as to generate an air flow from the upper side to the lower side of the target space with respect to the position where the air conditioner is installed, so that the circulator can be operated appropriately for the heating operation of the air conditioner, and reliably Energy saving effect can be obtained.

  Further, according to the present invention, when a humidity increase of a preset width occurs during a preset time, that is, when a cooling operation of the air conditioner is started, a significant increase in humidity is detected, and the circulator Since the fan is driven so as to generate an air flow from the lower side to the upper side of the target space with respect to the position where the air conditioner is installed, the circulator can be operated appropriately for the cooling operation of the air conditioner. Energy saving effect can be obtained.

  According to the present invention, the control unit starts the operation of the fan when both a change in temperature of a preset width and a change in humidity of a preset width occur during a preset time. Therefore, it is possible to distinguish between a change in room humidity that occurs in cases other than the start of operation of the air conditioner, for example, when the weather changes suddenly, and a change in room humidity due to the operation of the air conditioner, The operation of the circulator can be started appropriately.

  Further, according to the present invention, when both the temperature increase of the preset width and the humidity decrease of the preset width occur during the preset time, that is, the heating operation of the air conditioner is started. Since the fan is driven to generate an air flow from the upper side of the target space to the lower side based on the position where the circulator is installed, based on the detection of both a significant rise in temperature and a significant drop in humidity. A circulator suitable for heating operation of the air conditioner can be operated, and an energy saving effect can be obtained with certainty.

  Further, according to the present invention, when both the temperature decrease of the preset width and the humidity increase of the preset width occur during the preset time, that is, the cooling operation of the air conditioner is started. Since the fan is driven so as to generate an air flow from the lower side of the target space, based on the position where the circulator is installed, with reference to the position where the circulator is installed, as a result of detecting both a significant decrease in temperature and a significant increase in humidity. A circulator suitable for cooling operation of the air conditioner can be operated, and an energy saving effect can be obtained with certainty.

  Further, according to the present invention, the temperature and / or temperature difference between the two points of the point including the indoor ceiling or the vicinity of the ceiling and the point including the indoor floor or the vicinity of the floor surface is supplementarily used for controlling the circulator. Furthermore, the operation of the circulator can be controlled with high accuracy, and an energy saving effect can be obtained more and more.

  Further, according to the present invention, the temperature difference between the ceiling of the room or the vicinity of the ceiling and the floor or the floor surface generated when the cooling operation or the heating operation is started, and the relative humidity of the room at that time are detected, and the operation of the circulator is performed. Since it is started, it is possible to detect the operation of the air conditioner more reliably and to properly detect the circulator compared to the case of starting the circulator that relies only on the temperature difference between the ceiling of the room or near the ceiling and the floor or near the floor. Therefore, the energy saving effect can be obtained with certainty.

  According to the present invention, the operation of the circulator is started when it is detected that the relative humidity of the room has reached the predetermined relative humidity according to the time and season. As a preferred method for setting the relative humidity that is set in advance, from the past meteorological data for each region where this circulator is used, it is not reached if the air conditioner is not driven at that time, but it is not reached. The relative humidity reached when the machine is driven should be used. In this way, the operation of the air conditioner can be estimated and detected according to the time and season, and the operation of the circulator can be started appropriately, so that an energy saving effect can be reliably obtained.

  Further, according to the present invention, the necessity of operation of the circulator is determined from the time, season, time zone, and the absolute humidity and relative humidity of the room, and the circulator is operated if necessary. As a result, the operation of the air conditioner can be estimated and detected according to the time, season, and time zone, and the operation of the circulator can be appropriately started, so that an energy saving effect can be reliably obtained.

<First Embodiment>
A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view showing a circulator of this embodiment. The circulator 1 has a main body held by a housing 2, and a humidity sensor 3 is provided in the housing 2. The humidity sensor 3 is installed so as to come into contact with the air outside the casing 2 of the circulator 1, and can detect the humidity of the air in the vicinity of the circulator 1. Inside the housing 2, a ventilation path 6 that communicates from the suction port 4 to the blowout port 5 is formed. A blower 7 for sending air is disposed in the blower path 6. The fan used for the blower 7 is a sirocco fan 7b. In addition, operation control such as starting and stopping of the blower 7 and adjustment of the air volume is performed by the control unit 8 based on detection information of the humidity sensor 3. In addition, the suction port 4 of the circulator 1 can also be provided with a filter (not shown). In this case, the circulator 1 functions as an air cleaner.

  When the blower 7 is activated by the instruction from the control unit 8 and the circulator 1 starts to be driven, the air in front of the circulator 1 is sucked from the suction port 4 and flows through the blower path 6 from the blower outlet 5 to above the circulator 1 It is sent out vigorously. Thereby, the air in the room is circulated to suppress the temperature unevenness in the room.

  The room in which the circulator 1 is installed is a rectangular room R composed of a ceiling surface S, a floor surface F, side walls W1, W2, W3, and W4, as shown in FIG. It is secured. A section obtained by cutting the room R into two at the central vertical plane is referred to as a section D. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2700 mm). Further, the temperature distribution of the cross section D will be shown later. As shown in FIG. 3, the temperature measurement points are 5 points in the height direction at a distance of 600 mm and 7 points in the horizontal direction in the cross section D, for a total of 35 points. Measured.

  On one side wall W1 of the room R, an air conditioner 9 is provided so as to be divided into left and right by a cross section D. In general, it has been reported that the circulator 1 is effective when installed on the side wall W2 opposite to the side wall W1 where the air conditioner 9 is installed. The circulator 1 is installed in a corner part surrounded by F so as to be divided into left and right by a cross section D. At this time, a position where the humidity sensor 3 is arranged is a point K.

  In the room R described above, the heating operation (set temperature 26 ° C., automatic heating operation) of the conventional air conditioner 9A was performed with the circulator 1 stopped from the winter temperature of 5 ° C. and relative humidity of 40%. The result of having measured the time transition of the temperature and humidity in the point K of the room R in that case is shown in FIGS. FIG. 4 shows the time transition of the temperature at the point K in the room R, the horizontal axis shows the elapsed time, and the vertical axis shows the temperature. Moreover, FIG. 5 shows the time transition of the temperature at the point K of the room R, the horizontal axis shows the elapsed time, and the vertical axis shows the relative humidity. 6 shows the temperature distribution of the cross section D of the room R 30 minutes after the start of the heating operation of the air conditioner 9A, and FIG. 7 shows the air flow of the heating operation of the air conditioner 9A at that time. An outline of the behavior is shown.

  Further, in the room R, the heating operation (set temperature) of the air conditioner 9B improved in Patent Document 5 in a state where the circulator 1 is stopped from the state where the temperature is 5 ° C. and the relative humidity is 40% in winter. FIGS. 9 and 10 show the results of measuring the time transitions of the temperature and humidity at the point K in the room R when performing 26 ° C. and automatic heating operation). The measurement position, the horizontal axis, and the vertical axis in FIGS. 9 and 10 are the same as those in FIGS. FIG. 11 shows the temperature distribution of the cross section D of the room R after 30 minutes from the start of the heating operation of the air conditioner 9B, and FIG. 12 shows the airflow of the heating operation of the air conditioner 9B at that time. An outline of the behavior is shown.

  From the above, when the room R is heated in the air conditioner 9A and the air conditioner 9B, the temperature transition (FIGS. 4 and 9) and the humidity (FIGS. 5 and 10) at the point K are substantially the same. On the other hand, the temperature distribution (FIGS. 6 and 11) of the cross section D of the room R after 30 minutes from the start of the heating operation is greatly different, and in particular, the temperatures of the ceiling surface S and the floor surface F have different trends. . In the case of the conventional air conditioner 9A, the temperature in the vicinity of the ceiling surface S> the temperature in the vicinity of the floor surface F. In the improved air conditioner 9B described in Patent Document 5, the temperature in the vicinity of the ceiling surface S <the floor The temperature is near the surface F. That is, in the temperature and temperature difference between the ceiling surface S and the floor surface F, as a result of recent research and development on air conditioners, there is a clearly different tendency from the case of operation of conventional air conditioners.

  Next, in the room R described above, the cooling operation of the conventional air conditioner 9C (set temperature 26 ° C., automatic cooling operation) with the circulator 1 stopped from the state where the temperature is 35 ° C. and the relative humidity is 60% in summer. FIG. 14 and FIG. 15 show the results of measuring the time transition of the temperature and humidity at the point K of the room R in the case of performing the above. The measurement position, the horizontal axis, and the vertical axis in FIGS. 14 and 15 are the same as those in FIGS. FIG. 16 shows the temperature distribution of the cross section D of the room R 30 minutes after the start of the cooling operation of the air conditioner 9C, and FIG. 17 shows the air flow of the cooling operation of the air conditioner 9C at that time. An outline of the behavior is shown.

  Further, in the room R, the cooling operation (set temperature) of the air conditioner 9 </ b> D improved as described in Patent Document 4 in a state where the circulator 1 is stopped from the state where the temperature is 35 ° C. and the relative humidity is 60% in summer. FIGS. 19 and 20 show the results of measuring the time transition of the air temperature and humidity at the point K in the room R when performing 26 ° C. and automatic cooling operation). The measurement position, the horizontal axis, and the vertical axis in FIGS. 19 and 20 are the same as those in FIGS. FIG. 21 shows the temperature distribution of the cross section D of the room R 30 minutes after the start of the cooling operation of the air conditioner 9D, and FIG. 22 shows the airflow of the cooling operation of the air conditioner 9D at that time. An outline of the behavior is shown.

  From the above, when the room R is air-cooled in the air conditioner 9C and the air conditioner 9D, the temperature transition (FIGS. 14 and 19) and the humidity (FIGS. 15 and 20) at the point K are substantially the same. On the other hand, the temperature distribution (FIGS. 16 and 21) of the cross section D of the room R after 30 minutes from the start of the cooling operation is greatly different, and in particular, the temperatures of the ceiling surface S and the floor surface F have different trends. . In the case of the conventional air conditioner 9C, the temperature in the vicinity of the ceiling surface S> the temperature in the vicinity of the floor surface F. In the case of the air conditioner 9D improved as described in Patent Document 4, the temperature in the vicinity of the ceiling surface S <the floor surface. The temperature is in the vicinity of F. That is, in the temperature and temperature difference between the ceiling surface S and the floor surface F, as a result of recent research and development on air conditioners, there is a clearly different tendency from the case of operation of conventional air conditioners.

  A large difference in the temperature and temperature difference between the ceiling surface S and the floor surface F when the room R is heated by the conventional air conditioner 9A and the air conditioner 9B improved as described in Patent Document 5, And from the big difference of the tendency of the temperature of the ceiling surface S and the floor surface F at the time of carrying out the air_conditioning | cooling operation of the room R by the air conditioner 9D by which the improvement described in the conventional air conditioner 9C and patent document 4 was made It can be seen that it is difficult to determine the activation timing of the circulator 1 based only on the temperature and temperature difference between the ceiling surface S and the floor surface F.

  On the other hand, especially regarding the humidity condition of the room R, even when the room R is heated by the conventional air conditioner 9A and the air conditioner 9B improved in Patent Document 5, the air conditioner 9 When the set temperature is the same, the tendency is substantially the same as shown in FIGS. Further, even when the room R is cooled by the conventional air conditioner 9C and the air conditioner 9D improved as described in Patent Document 4, when the set temperature of the air conditioner 9 is the same, FIG. 15 and FIG. As shown, the trends are almost the same. Therefore, if the start timing of the circulator 1 is determined based on the humidity, the difference due to the difference in the air conditioner as described above is eliminated or becomes relatively small, so that appropriate start-up is possible.

  The circulator 1 of the present invention uses this phenomenon to determine the start timing of the circulator 1. A method for determining the start timing of the circulator 1 based on humidity will be described below.

  First, during heating, from FIG. 4, FIG. 5, FIG. 9, and FIG. 10, as the operation of the air conditioner 9 starts, the room temperature of the room R (the temperature at the point K) increases rapidly, The relative humidity in room R (relative humidity at point K) decreases rapidly. In the circulator 1 of the present invention, for example, when the humidity sensor 3 senses a decrease in relative humidity of 1% or more in 1 minute, the control unit 8 activates the blower 7 and starts driving the circulator 1. Perform control action.

  Next, during cooling, from FIG. 14, FIG. 15, FIG. 19, and FIG. 20, as the operation of the air conditioner 9 starts, the room temperature of the room R (the temperature at the point K) rapidly decreases, and accompanying this, The relative humidity in the room R (relative humidity at the point K) increases rapidly. In the circulator 1 of the present invention, for example, when the humidity sensor 3 senses an increase in relative humidity of 1% or more in 1 minute, the control unit 8 starts the blower 7 and starts driving the circulator 1. Perform control action.

  By doing in this way, it becomes possible to start appropriately without depending on the temperature or temperature difference of the ceiling surface or floor surface due to the difference of the air conditioner, and the effect of the circulator 1 can always be sufficiently obtained. An energy saving effect can be obtained with certainty.

  Specifically, when the room R is heated by the conventional air conditioner 9A, in a state where the drive control of the circulator 1 according to the first embodiment is performed, as shown in FIG. The temperature difference between the floor surface and the ceiling surface in the section D of the room R is 6 to 7 ° C. In the state in which the drive control of the circulator 1 according to the first embodiment is performed, as shown in FIG. , Relaxed to 3-4 ° C. Further, when the room R is heated by the air conditioner 9B improved as described in Patent Document 5, when the circulator 1 is stopped, as shown in FIG. 11, a cross section D of the room R after 30 minutes has elapsed. The temperature difference between the vicinity of the floor surface and the vicinity of the ceiling surface is 5 to 6 ° C., but in the state where the drive control of the circulator 1 according to the first embodiment is performed, as shown in FIG. To be relaxed. Further, when the room R is cooled by the conventional air conditioner 9C, when the circulator 1 is stopped, as shown in FIG. 16, the vicinity of the floor surface and the ceiling surface of the cross section D of the room R after 30 minutes have elapsed. The temperature difference of 6 to 7 ° C. is relaxed to 3 to 4 ° C. as shown in FIG. 18 in the driving state of the circulator 1. In addition, when the room R was heated by the air conditioner 9D improved as described in Patent Document 5, the drive control of the circulator 1 according to the first embodiment was performed even when the circulator 1 was stopped (FIG. 11). Even in the state (FIG. 23), the effect cannot be obtained so much.

  In addition, for example, the room is large, the shape is not rectangular, and the shape is L-shaped, the vertical and horizontal dimensions differ greatly, so-called vertical or horizontal rooms, or the ceiling is very high. In the case of a simple shape, the temperature of the ceiling surface and floor surface of the room R varies significantly depending on the location, but the variation due to the location of the relative humidity of the room R is relatively small. Compared to control that depends on surface temperature and temperature difference, control by relative humidity enables more appropriate startup, and the effect of the circulator 1 can always be sufficiently obtained, and the energy saving effect can be obtained more reliably. Can do.

  Specifically, in an L-shaped room R ′ as shown in FIG. 24, conventional air is applied to the end of the wide wall facing the rear wall surface of the protruding wavy region at an angle when the rear wall surface is viewed obliquely. Consider a case in which a conditioner 9A is provided and a heating operation is performed by the air conditioner 9A. In this case, it is very difficult to harmonize the air in the broken line area. Therefore, as shown in FIG. 24, the circulator 1 is installed at the end of the back wall surface far from the air conditioner 9A so that air conditioning can be performed up to the broken line area. However, even if the air conditioner 9A is driven, a temperature difference is unlikely to occur between the ceiling and the floor surface in the broken line area, so that the driving of the circulator 1 is not started by the conventional method. However, in the case of the first embodiment, since the humidity at the position of the circulator 1 changes, the circulator 1 can be driven appropriately. When the circulator cannot be driven, as shown in FIG. 25 (b), in the L-shaped room R ′, the temperature distribution in the horizontal plane 600 mm above the floor during heating is the temperature between the central portion of the room R ′ and the protruding wavy region. When the circulator 1 cannot be driven when the difference is 6 to 7 ° C., the temperature is reduced to 3 to 4 ° C. as shown in FIG.

  It should be noted that the diffusion of humidity is very fast compared to the diffusion of temperature, so even if large temperature irregularities are formed in the room, the humidity will spread over it, so the start of circulator operation should be judged by humidity. This makes it possible to start the circulator more quickly and appropriately than when judging the start of the circulator based only on the temperature. In addition, since it is possible to suppress the occurrence of problems such as the operation not starting easily even though the circulator is required to operate, an energy saving effect can be obtained with certainty.

  Table 1 shows the appropriate degree of start of the operation of the circulator depending on the difference between the method of the first embodiment and the conventional method (starting driving based on the difference between the floor surface temperature and the ceiling surface temperature).

  The effects of the present invention are summarized as follows. That is, the present invention includes a fan that causes an air flow in the target space and a control unit that controls the operation of the fan, and detects the humidity of the air in the target space in a circulator for reducing temperature unevenness in the target space. The controller is configured to start the operation of the fan when a change in humidity of a preset width occurs during a preset time.

  It is known that when the air conditioner is operated in a room where a certain degree of airtightness is maintained, the humidity of the air in the room fluctuates rapidly. For example, when the cooling operation is started, the room temperature rapidly decreases. However, the absolute humidity of the room does not vary greatly. Therefore, the relative humidity of the room is greatly increased. For example, when the heating operation is started, the temperature of the room rapidly increases. However, the absolute humidity of the room does not vary greatly. Therefore, the relative humidity of the room is greatly reduced. Even if the air conditioner has been functionally and structurally improved so that the above-mentioned temperature unevenness is greatly reduced, the room shape is large or irregular. This is a phenomenon that can be said when the room is kept airtight to some extent.

  According to the present invention, when the humidity change of a preset width occurs in the room, the control unit starts the operation of the fan, so whether the cooling operation is started or the heating operation is started. When a large change in humidity is detected, the operation of the circulator is started. As a result, when a temperature distribution that cannot be assumed in the past is generated, for example, when functional and structural improvements are made such that the above-described temperature unevenness is greatly reduced in the air conditioner Or, even when the shape of the room is large or an irregular shape, the operation of the air conditioner can be reliably detected and the operation of the circulator can be started appropriately, An energy saving effect can be obtained with certainty.

  In the above embodiment, the operation start of the circulator is controlled by the rate of change of the relative humidity. However, as is apparent from FIGS. 5, 10, 15, and 20, the relative humidity during heating operation is less than 15% immediately after the start of operation, and the relative humidity during cooling operation is approximately 100% immediately after the start of operation. become. Therefore, although there is a change due to climate, time, etc., basically, if the relative humidity is set to 15% during heating and the relative humidity is set to 95% during cooling, the operation of the air conditioner can be detected almost certainly. Is possible. Therefore, the start of operation of the circulator can also be controlled by detecting a predetermined value of the relative humidity. In this case, in order to increase the accuracy, the relative humidity value at the start of operation may be determined according to the location of the circulator such as the area, climate, and time.

<Another embodiment according to the first embodiment>
Next, another embodiment according to the first embodiment will be described. The circulator 1 according to the present embodiment is configured by a temperature / humidity sensor 3b (not shown) that detects the temperature as well as the relative humidity instead of the humidity sensor 3 with respect to the circulator 1 according to the first embodiment. Other parts are the same as those in the first embodiment.

  In the circulator 1 of the present invention, for example, the temperature / humidity sensor 3b senses an increase in temperature of 1 ° C. or more in 1 minute and senses a decrease in relative humidity of 1% or more in 1 minute, or 1 When detecting a temperature drop of 1 ° C. or more per minute and a rise in relative humidity of 1% or more per minute, the control unit 8 activates the blower 7 to detect the circulator. The control operation is performed so that the driving of No. 1 is started.

  The effects of the present invention are summarized as follows. That is, the present invention further includes a temperature sensor that detects the temperature of the air in the target space with respect to the circulator 1 according to the first embodiment, and the temperature change with a preset width during a preset time is preset. The control unit starts the operation of the fan when both changes in the humidity of the width occur.

  The humidity of the room is also assumed when the air conditioner is not started. For example, when the weather changes suddenly. According to this configuration, since the operation of the circulator is started by obtaining both humidity and temperature information, for example, when the humidity of the environment suddenly increases due to the approach of the warm front, and the operation of the air conditioner A distinction is made when the is started.

  This makes it possible to distinguish a change in room humidity that occurs when the air conditioner suddenly changes, such as when the weather changes suddenly, and a change in room humidity that accompanies the operation of the air conditioner. Can properly start the circulator operation.

<Second Embodiment>
Next, FIGS. 26 and 27 are side sectional views showing a circulator according to the second embodiment. The same parts as those in the first embodiment shown in FIGS. 1 and 2 are denoted by the same reference numerals. The circulator 1b of this embodiment differs from the circulator 1 of the first embodiment in the following points. First, on the downstream side of the blower 7, the blower path 6 is branched into two, one blower path 6A extends upward and communicates with the blowout port 5A provided on the top surface of the housing 2, and the other blower path 6B is downward. And communicates with the air outlet 5B provided at the lower front of the housing 2. Further, dampers 10A and 10B are provided in the air supply path 6A and the air supply path 6B, respectively. Then, as shown in FIG. 26, when the air blowing path 6A is opened by the damper 10A and the air blowing path 6B is closed by the damper 10B, the air sucked from the suction port 4 flows into the room R from the air outlet 5A. It is sent out vigorously toward the upper side (ceiling surface S) (in the direction of arrow A in FIG. 26). In addition, as shown in FIG. 27, when the air blowing path 6A is closed by the damper 10A and the air blowing path 6B is opened by the damper 10B, the air sucked from the suction port 4 flows into the room R from the air outlet 5B. It is sent out vigorously downward (floor surface F) (in the direction of arrow B in FIG. 27). Other parts are the same as those in the first embodiment.

  In the circulator 1b of this embodiment, when the humidity sensor 3 senses a decrease in relative humidity of 1% or more in 1 minute, the control unit 8 opens the damper 10A, closes the damper 10B, and activates the blower 7. A control operation is performed so that driving of the circulator 1 is started.

  When the humidity sensor 3 detects an increase in relative humidity of 1% or more in 1 minute, the control unit 8 closes the damper 10A, opens the damper 10B, starts the blower 7, and starts driving the circulator 1. The control operation is performed as described.

  By doing in this way, when the sudden fall of humidity is detected, it sends out vigorously toward the upper direction (ceiling surface S) of room R from blower outlet 5A. As described above, when a rapid decrease in humidity is detected, the room R has started heating operation by the air conditioner 9, and therefore air near the floor surface F of the room R is sent to the vicinity of the ceiling surface S. As a result, temperature unevenness in the room R can be reduced. Further, when a rapid increase in humidity is detected, the humidity is sent out from the blowout port 5B toward the lower part of the room R (floor surface F). As described above, when a rapid increase in humidity is detected, the room R has started cooling operation by the air conditioner 9, and therefore air near the ceiling surface S of the room R is sent to the vicinity of the floor surface F. As a result, temperature unevenness in the room R can be reduced. That is, since it is possible to determine whether the room R is currently heated or cooled by a rapid decrease in humidity or a rapid increase in humidity, and accordingly, a flow in an appropriate wind direction can be created in the room R. Thus, the effect of reducing the temperature unevenness of the circulator can be obtained.

  The effects of the present invention are summarized as follows. That is, according to the present invention, in the circulator having the above-described configuration, when a decrease in humidity of a preset width occurs during a preset time, the position where the circulator is installed is used as a reference from the upper side to the lower side of the target space. The fan is driven to generate an air flow. According to this configuration, when the heating operation of the air conditioner is started, the circulator is operated so as to detect a significant decrease in humidity and generate an air flow downward from above the target space. The circulator suitable for the heating operation can be operated, and an energy saving effect can be obtained with certainty.

  Further, according to the present invention, in the circulator configured as described above, when a humidity increase of a preset width occurs during a preset time, the position where the circulator is installed is used as a reference from the lower side to the upper side of the target space. The fan is driven to generate an air flow. According to this configuration, when the cooling operation of the air conditioner is started, a significant increase in humidity is detected, and the circulator is operated so as to generate an air flow upward from below the target space. Therefore, it is possible to operate the circulator suitable for the cooling operation, and to surely obtain the energy saving effect.

<Another embodiment according to the second embodiment>
Next, another embodiment according to the second embodiment will be described. The circulator 1b of the present embodiment is configured by a temperature / humidity sensor 3b (not shown) that detects the temperature together with the relative humidity instead of the humidity sensor 3 with respect to the circulator 1b of the second embodiment. Other parts are the same as those of the second embodiment.

  In the circulator 1b of the present invention, when the temperature / humidity sensor 3b senses an increase in temperature of 1 ° C. or more in 1 minute and senses a decrease in relative humidity of 1% or more in 1 minute, the controller 8 controls the damper 10A. Is opened, the damper 10B is closed, the blower 7 is started, and the control operation is performed so that the driving of the circulator 1 is started.

  Further, when the temperature / humidity sensor 3b senses a decrease in temperature of 1 ° C. or more in 1 minute and also senses an increase in relative humidity of 1% or more in 1 minute, the control unit 8 closes the damper 10A, and the damper 10B. Is opened, the blower 7 is started, and the control operation is performed so that the circulator 1 starts to be driven.

  By doing in this way, when a rapid increase in temperature and a rapid decrease in humidity are sensed simultaneously, the air is sent out vigorously from the outlet 5A toward the upper side of the room R (ceiling surface S). As described above, when a rapid increase in temperature and a rapid decrease in humidity are detected at the same time, the room R has started heating operation by the air conditioner 9, so the air in the vicinity of the floor surface F of the room R is used as the ceiling surface. By sending it to the vicinity of S, the temperature unevenness of the room R can be reduced. Further, when a rapid decrease in temperature and a rapid increase in humidity are detected at the same time, it is sent out vigorously from the outlet 5B toward the lower part of the room R (floor surface F). As described above, when a rapid decrease in temperature and a rapid increase in humidity are detected at the same time, the room R has started cooling operation by the air conditioner 9, and therefore air near the ceiling surface S of the room R is used as the floor surface. By sending it to the vicinity of F, the temperature unevenness of the room R can be reduced. That is, it is determined whether the room R is currently heated or cooled by either a rapid increase in temperature and a rapid decrease in humidity, or a rapid decrease in temperature and a rapid increase in humidity. Correspondingly, a flow of an appropriate wind direction can be created in the room R, so that the effect of reducing the temperature unevenness of the circulator can be obtained more appropriately.

  The effects of the present invention are summarized as follows. That is, the present invention further includes a temperature sensor for detecting the temperature of the air in the target space with respect to the circulator 1b of the second embodiment, and the temperature is increased in a preset range during a preset time. The fan is driven so as to generate an air flow from the upper side to the lower side of the target space with reference to the position where the circulator is installed, when both the width and the humidity decrease. According to this configuration, when the heating operation of the air conditioner is started, the circulator is operated so as to detect a significant increase in temperature and a significant decrease in humidity and to generate an air flow from the top to the bottom of the target space. Therefore, the operation of the circulator suitable for the heating operation of the air conditioner can be performed, and the energy saving effect can be surely obtained.

  Further, according to the present invention, in the circulator configured as described above, a circulator is installed when both a decrease in temperature of a preset width and an increase in humidity of a preset width occur during a preset time. Based on the position, the fan is driven so as to generate an air flow from the lower side to the upper side of the target space. According to this configuration, when the cooling operation of the air conditioner is started, a significant decrease in temperature and a significant increase in humidity are detected, and the circulator is operated so that air flows upward from below the target space. Therefore, the operation of the circulator suitable for the cooling operation of the air conditioner can be performed, and the energy saving effect can be surely obtained.

<Third Embodiment>
Next, FIG. 28 is a side sectional view showing the circulator of the third embodiment. The same parts as those in the first embodiment shown in FIGS. 1 and 2 are denoted by the same reference numerals. The circulator 1c of this embodiment differs from the circulator 1 of the first embodiment in the following points. First, the blower 7 includes a reversible fan 7c that can rotate in both the forward direction and the reverse direction. When the reversible fan 7c rotates in the forward direction, the direction of the arrow A in the figure, that is, the indoor air is sucked from the suction port 4 and is directed from the blowout port 5 to above the room R (ceiling surface S). It is sent out vigorously. When the reversible fan 7c rotates in the reverse direction, the direction of the arrow B in the figure, that is, the indoor air, on the contrary, is sucked from the blower outlet 5 and below the room R (floor from the suction port 4). It is sent out vigorously towards surface F). Further, instead of the humidity sensor 3, a temperature / humidity sensor 3 b that detects the temperature as well as the relative humidity is provided, and a temperature sensor 11 that can detect the temperature of the ceiling surface S and the floor surface F of the room R is further provided. . As the temperature sensor 11, an infrared sensor, a temperature sensor based on image recognition, or the like can be used as appropriate, and the temperature of the ceiling surface S and the floor surface F of the room R may be detected. The air temperature in the vicinity of the surface F may be detected, the temperature difference between the ceiling surface S and the floor surface F may be detected, and the air temperature in the vicinity of the ceiling surface S and the air in the vicinity of the floor surface F may be detected. What detects a temperature difference with temperature may be used. Other parts are the same as those in the first embodiment.

  In the circulator 1c of the present invention, the temperature / humidity sensor 3b senses an increase in temperature of 1 ° C. or more in 1 minute and senses a decrease in relative humidity of 1% or more in 1 minute, When the temperature difference between the ceiling surface S and the floor surface F of the room R is detected to be 10 ° C. or higher and the humidity is detected by the temperature / humidity sensor 3b to be 30% or lower. The control unit 8 activates the blower 7 so that the reversible fan 7c rotates in the forward direction, and performs a control operation so that driving of the circulator 1c is started.

  Further, the temperature / humidity sensor 3b senses a decrease in temperature of 1 ° C. or more in 1 minute, and also senses an increase in relative humidity of 1% or more in 1 minute, or the temperature sensor 11 detects the temperature of the room R. When the temperature difference between the ceiling surface S and the floor surface F is detected to be 10 ° C. or more, and the temperature / humidity sensor 3b detects that the humidity is 60% or more, the control unit 8 Then, the blower 7 is activated so that the reversible fan 7c rotates in the reverse direction, and a control operation is performed so that driving of the circulator 1c is started.

  In this way, when a rapid increase in temperature and a rapid decrease in humidity are sensed at the same time, or a large difference between the temperature of the ceiling surface S and the floor surface F of the room R is detected and the room When the relative humidity of the air is sensed to be lower than the preset relative humidity, the air sucked from the air inlet 4 is directed from the air outlet 5 to above the room R (ceiling surface S) as shown by the arrow in FIG. It is sent out in the direction of A vigorously. As described above, when a rapid increase in temperature and a rapid decrease in humidity are sensed at the same time, or the temperature between the ceiling surface S and the floor surface F of the room R is large, and the relative humidity of the room is preset. When the relative humidity is lower than the room R, the room R has started heating operation by the air conditioner 9, and therefore the air in the vicinity of the floor surface F of the room R is sent to the vicinity of the ceiling surface S. R temperature unevenness can be reduced.

  In addition, when a rapid decrease in temperature and a rapid increase in humidity are detected at the same time, or when a large difference has occurred in the temperature between the ceiling surface S and the floor surface F of the room R, the relative humidity of the room is set in advance. When it is sensed that the relative humidity is higher than the set relative humidity, the air sucked from the blowout port 5 is directed from the suction port 4 to the lower side of the room R (floor surface F) in the direction of arrow B in FIG. It is often sent out. As described above, when a rapid decrease in temperature and a rapid increase in humidity are detected at the same time, or the temperature between the ceiling surface S and the floor surface F of the room R is greatly different and the relative humidity of the room is set in advance. When the relative humidity is higher than the room humidity, the room R has started cooling operation by the air conditioner 9, and therefore, by sending the air near the ceiling surface S of the room R to the vicinity of the floor surface F, the room R R temperature unevenness can be reduced.

  That is, when there is a large difference between the temperature of the ceiling surface S and the floor surface F of the room R, or a rapid increase in temperature and a rapid decrease in humidity, or a rapid decrease in temperature and a rapid increase in humidity. It is possible to determine whether the room R is currently heated or cooled according to any of the relative humidity of the room, and accordingly, a flow of an appropriate wind direction can be created in the room R. Accordingly, the temperature of the circulator can be increased. The effect of reducing unevenness can be obtained.

  The effects of the present invention are summarized as follows. That is, in the circulator having the above-described configuration, the temperature difference between the point including the indoor ceiling or the vicinity of the ceiling and the point including the indoor floor or the vicinity of the floor surface is not less than a preset temperature difference, The control unit starts the operation of the fan by comparing the humidity of the room with a preset humidity. According to this configuration, it senses that there is a large difference in temperature between the ceiling of the room or near the ceiling and the floor or near the floor, and senses that the relative humidity of the room is lower than the preset relative humidity. Or when it is detected that there is a large difference between the temperature of the ceiling and floor of the room and the relative humidity of the room is higher than a preset relative humidity. Since the part starts the operation of the fan, the temperature difference between the ceiling of the room or the vicinity of the ceiling and the floor or the vicinity of the floor surface when the cooling operation is started or the heating operation is started, Since both the relative humidity of the room at that time is detected and the circulator starts to operate, it depends only on the temperature difference between the ceiling of the room or near the ceiling and the floor or near the floor. Than in the case of activation of the calculator, can be more reliably detect the operation of the air conditioner, it is possible to start the operation of the appropriate circulator, can be obtained reliably energy saving effect.

<Another embodiment according to the third embodiment>
Next, another embodiment according to the third embodiment will be described. The circulator 1c according to this embodiment is different from the circulator 1c according to the third embodiment in that the temperature / humidity sensor 3b and the temperature sensor 11 are abolished, and instead, the same humidity sensor 3 as that in the first embodiment is provided. Further, the control unit 8 has a calendar function as a means for determining the current time, can grasp the current date, time and season, and as a database for determining the average humidity due to the climate of the area, for example, It has historical weather data (temperature / humidity) by month and hour for each region in Japan. Other parts are the same as those of the third embodiment.

  In the circulator 1c of the present invention, it is desirable to first set the area where the circulator 1c is installed and the current date and time before use. This may be set in advance at the time of factory shipment assuming the area to be used, or may be set by the user.

  In this embodiment, for example, when the place of use is set as “Honshu Pacific side”, when the humidity sensor 3 senses that the relative humidity is 90% or more in July, August, and September. The control unit 8 activates the blower 7 so that the reversible fan 7c rotates in the forward direction, and performs a control operation so that driving of the circulator 1c is started. Further, in December, January, and February, when the humidity sensor 3 senses that the relative humidity is 15% or less, the control unit 8 turns the blower 7 so that the reversible fan 7c rotates in the reverse direction. The control operation is performed so that the circulator 1c starts to be driven.

  In this embodiment, for example, when the place of use is set as “Honshu-Japan Sea side area”, the humidity sensor 3 senses that the relative humidity has reached 80% or more in July, August, and September. Then, the control unit 8 activates the blower 7 so that the reversible fan 7c rotates in the forward direction, and performs a control operation so that driving of the circulator 1c is started. Further, in December, January, and February, when the humidity sensor 3 senses that the relative humidity is 40% or less, the control unit 8 turns the blower 7 so that the reversible fan 7c rotates in the reverse direction. The control operation is performed so that the circulator 1c starts to be driven.

The relationship between the above areas and the preset humidity is based on past weather data by area.
In the summer, for example, the value of {past average humidity + (past maximum humidity−past average humidity) / 2} is used, and in the winter, for example, {past average humidity− (past average humidity−past average humidity−past The method of setting each value of (minimum humidity) / 2} is simple. More desirably, the value is not reached when the air conditioner is not driven, but it is more reliable if the relative humidity value reached when the air conditioner is driven is adopted.

  By doing in this way, the effect similar to the said 3rd Embodiment can be acquired with a simpler structure.

  The effects of the present invention are summarized as follows. That is, the present invention includes a fan that causes an air flow in the target space and a control unit that controls the operation of the fan, and detects the humidity of the air in the target space in a circulator for reducing temperature unevenness in the target space. A humidity sensor for determining the current time, and when the humidity reaches a preset humidity at a preset time, the control unit starts operating the fan. According to this configuration, the means for determining the time determines whether the time is summer or winter, and the circulator is operated when the relative humidity of the room reaches a relative humidity set in advance according to the season. Since the operation of the air conditioner can be estimated and detected according to the time and season and the operation of the circulator can be started appropriately, an energy saving effect can be obtained with certainty. For example, in the summer season, the circulator is operated when the relative humidity of the room rises above a preset relative humidity (for example, 90%). For example, in the winter season, the relative humidity (for example, 15%) or less is set. If the relative humidity of the room decreases, the circulator is operated. As a preferable method for setting the relative humidity set in advance, it is determined from past weather data for each region where this circulator is used, and a suitable value is appropriately adopted. Desirably, the relative humidity that is reached when the air conditioner is driven but not reached when the air conditioner is not driven may be adopted at that time.

<Another embodiment according to the third embodiment>
Next, still another embodiment according to the third embodiment will be described. The circulator 1c according to the present embodiment is provided with a humidity sensor 3c that can simultaneously detect the absolute humidity and the relative humidity of the room instead of the other circulator 1c according to the third embodiment. Other parts are the same as those of the third embodiment.

  In the present embodiment, for example, when the place of use is set to “Japan”, the absolute humidity and the relative humidity of the air in the room are detected, and the temperature is calculated from those values. For example, if the temperature calculated from the absolute humidity and the relative humidity is about 30 degrees during the day of July, August, and September, it is determined that the air conditioner is not operating, and the driving of the circulator 1c is started. Not. For example, during the day of July, August, and September, when the temperature calculated from the absolute humidity and the relative humidity is about 20 degrees, it is determined that the air conditioner is operating, and the control unit 8 is reversible. The blower 7 is activated so that the fan 7c rotates in the forward direction, and a control operation is performed so that driving of the circulator 1c is started. For example, in December, January, and February, when the temperature calculated from the absolute humidity and the relative humidity is about 10 degrees, it is determined that the air conditioner is not operating, and the driving of the circulator 1c is not started. For example, in December, January, and February, when the temperature calculated from the absolute humidity and the relative humidity is about 25 degrees, it is determined that the air conditioner is operating, and the control unit 8 determines that the reversible fan 7c The fan 7 is activated so as to rotate in the reverse direction, and the control operation is performed so that the driving of the circulator 1c is started.

  Specifically, for example, when the absolute humidity is 12 g / kg and the relative humidity is 40% during the day of July, August, and September, the room temperature is calculated as 32.2 ° C., and as a result, the air conditioner Is determined not to operate, and the circulator is not operated. For example, when the absolute humidity is 12 g / kg and the relative humidity is 90% during the day of July, August, and September, the room temperature is calculated to be 18.5 ° C. As a result, the air conditioner is operating. It is determined that the circulator is operated. For example, when the absolute humidity is 5 g / kg and the relative humidity is 60% during the day of December, January, and February, the room temperature is calculated as 11.4 ° C. As a result, the air conditioner is not operating. The circulator is not operated. For example, when the absolute humidity is 5 g / kg and the relative humidity is 15% during the day of December, January, and February, the room temperature is calculated to be 34.2 ° C, and as a result, the air conditioner is operating. It is determined that the circulator is operated.

  For example, when the place of use is set to “Australia”, the absolute humidity and relative humidity of the air in the room are detected, and the temperature is calculated from these values. For example, if the temperature calculated from the absolute humidity and the relative humidity is about 30 degrees during the day of December, January, and February, it is determined that the air conditioner is not operating, and the driving of the circulator 1c is started. Not. For example, if the temperature calculated from the absolute humidity and the relative humidity is about 20 degrees during the day of December, January, and February, the air conditioner is determined to be operating, and the control unit 8 is reversible. The blower 7 is activated so that the fan 7c rotates in the forward direction, and a control operation is performed so that driving of the circulator 1c is started. For example, in June, July, and August, when the temperature calculated from the absolute humidity and the relative humidity is about 10 degrees, it is determined that the air conditioner is not operating, and the driving of the circulator 1c is not started. For example, in June, July, and August, when the temperature calculated from the absolute humidity and the relative humidity is about 25 degrees, it is determined that the air conditioner is operating, and the control unit 8 determines that the reversible fan 7c. The fan 7 is activated so as to rotate in the reverse direction, and the control operation is performed so that the driving of the circulator 1c is started.
