As shown in FIG. 1, the dehumidifier according to this embodiment includes a housing 100. The housing 100 is configured to be self-supporting. The housing 100 is formed with a suction port 101 and an exhaust port 103. The suction port 101 is an opening for taking in the indoor air P into the housing 100. The exhaust port 103 is an opening for discharging the dry air Q from which the moisture has been removed from the housing 100 into the room. A water storage tank 102 is detachably attached to the lower part of the housing 100.

The dehumidifier according to this embodiment includes a wind direction variable portion 1. The wind direction variable portion 1 is provided at the exhaust port 103. The wind direction variable unit 1 is a wind direction variable means for changing the wind direction of the dry air Q blown out from the exhaust port 103.

As shown in FIG. 2, the wind direction variable portion 1 includes a vertical louver 1a, a horizontal louver 1b, a vertical variable motor 1c, and a horizontal variable motor 1d. The vertical louver 1a changes the vertical wind direction of the dry air Q. The lateral louver 1b changes the horizontal wind direction of the dry air Q. The vertical variable motor 1c rotates the direction of the vertical louver 1a in the vertical direction. The lateral variable motor 1d rotates the lateral louver 1b in the horizontal direction.

The vertical louver 1a has a rectangular opening extending in the width direction of the housing 100. The vertical louver 1a is configured to be rotatable in the vertical direction about the rotation axis of the vertical variable motor 1c. A plurality of horizontal louvers 1b are arranged, for example, at equal intervals in the vertical louvers 1a. Each horizontal louver 1b is axially supported so as to be rotatable in the horizontal direction on the back side opposite to the opening of the vertical louver 1a. The horizontal orientation of each lateral louver 1b is configured to be interlocked with the drive of the lateral variable motor 1d.

Inside the housing 100, an air passage leading from the suction port 101 to the exhaust port 103 is formed. As shown in FIG. 3, a blower fan 2 and a dehumidifying device 5 are provided in this air passage. The blower fan 2 is rotated by the fan motor 2a. The blower fan 2 generates an air flow from the suction port 101 to the exhaust port 103 in the above-mentioned air passage.

The dehumidifying device 5 removes moisture contained in the air in the air passage passing through the dehumidifying device 5. The dehumidifying device 5 may be any as long as it can remove and condense the moisture in the air, and for example, a general compressor method, a desiccant method, or the like can be used.

When the blower fan 2 is rotated by the fan motor 2a, the indoor air P is sucked into the housing 100 from the suction port 101. The indoor air P sucked into the housing 100 travels in the above-mentioned air passage, and when it passes through the dehumidifying device 5, moisture is removed to become dry air Q. Then, the generated dry air Q is blown into the room from the exhaust port 103. In this way, the blower fan 2 and the dehumidifying device 5 constitute a dehumidifying means that takes in the indoor air P into the housing 100 and removes moisture from the taken in indoor air P.

A water storage tank 102 is arranged below the dehumidifying device 5. The water removed from the indoor air P by the dehumidifying device 5 is condensed into condensed water C and falls into the water storage tank 102. In this way, the condensed water C is stored in the water storage tank 102.

A temperature sensor 3 and a humidity sensor 4 are installed on the suction port 101 side of the dehumidifying device 5 in the above-mentioned air passage of the housing 100. The temperature sensor 3 detects the temperature of the air in the air passage. That is, the temperature sensor 3 is a temperature detecting means for detecting the temperature of the indoor air P. The humidity sensor 4 detects the humidity of the air in the air passage. That is, it is a humidity detecting means for detecting the humidity of the indoor air P.

The dehumidifier according to this embodiment includes an infrared sensor 6. The infrared sensor 6 is a surface temperature detecting means for detecting the surface temperature of an object in a room in a non-contact manner. The infrared sensor 6 specifically detects the intensity of heat radiation (infrared rays) emitted from the surface of an object by using, for example, a thermoelectromotive force effect. The infrared sensor 6 includes an infrared absorbing film 6a and a thermistor 6b. The infrared absorbing film 6a is a film body that well absorbs electromagnetic waves in the infrared region. The thermistor 6b detects the temperature of the infrared absorbing film 6a.

The infrared sensor 6 determines the difference between the temperature of the heat-sensitive portion of the infrared absorbing film 6a (warm contact), which raises the temperature by absorbing heat radiation, and the temperature of the infrared absorbing film 6a (cold contact) detected by the thermista 6b. It is converted into an electric signal such as voltage and output. The control device 10 described later can detect the surface temperature of the object from the magnitude of the electric signal output from the infrared sensor 6.

As shown in FIG. 2, the infrared sensor 6 is attached to one side of a substantially central horizontal louver 1b arranged in the vertical louver 1a. By doing so, the direction of detecting the surface temperature by the infrared sensor 6 becomes substantially the same as the direction of the dry air Q blown out from the exhaust port 103. Therefore, the infrared sensor 6 configured in this way is an object to be dried, which is an object in the entire area within a range in which the dry air Q can be blown by the variable wind direction portion 1, specifically, for example, wet clothes after washing. The surface temperature of towels and the like can be detected.

The water storage tank 102 is provided with a float switch 9. The float switch 9 in this embodiment is an example of a water storage amount detecting means for detecting the water storage amount of the water storage tank 102. The float switch 9 includes a float (not shown). This float is arranged in the water storage tank 102 and has the property of floating on water. Therefore, the float floats on the water surface of the condensed water C in the water storage tank 102, and the position of the float moves up and down as the water surface of the condensed water C in the water storage tank 102 moves up and down. That is, the water level in the water storage tank 102 can be detected by the position of the float.

The float switch 9 operates when the position of the float reaches a preset position. The position of the float in which the float switch 9 operates is a position corresponding to the water level when the amount of water stored in the water storage tank 102 becomes the first amount of water stored. The first water storage amount is preset as a water storage amount for determining that the water storage tank 102 is full.

The dehumidifier according to this embodiment includes a control device 10. The control device 10 includes, for example, a microcomputer. As shown in FIG. 4, the control device 10 includes an input circuit 10a, an output circuit 10b, a CPU 10c, and a storage unit 10d. The control device 10 executes a preset process by executing the program stored in the storage unit 10d by the CPU 10c, and controls the operation of the dehumidifier. Further, the storage unit 10d also stores data and the like used for the processing at this time.

As shown in FIG. 4, the dehumidifier includes a display unit 7 and an operation switch 8. The operation switch 8 is an operation switch for starting and stopping the operation of the dehumidifier, setting the operation mode, and the like. The display unit 7 is a liquid crystal display that displays various information such as the operation mode of the dehumidifier, the temperature of the indoor air, and the humidity. The dehumidifier may be provided with a touch panel that also serves as a display unit 7 and an operation switch 8.

The operation signal output from the operation switch 8, the detection signal output from each of the temperature sensor 3 and the humidity sensor 4, and the signal output from the float switch 9 are input to the input circuit 10a of the control device 10. .. Although not shown in FIG. 4, as shown in FIG. 3, a signal output from the infrared sensor 6 is also input to the control device 10.

The CPU 10c performs predetermined processing on various signals input to the input circuit 10a. Then, a control signal is output from the output circuit 10b to the dehumidifying device 5, the fan motor 2a, and the display unit 7 according to the processing result. Further, although not shown in FIG. 4, as shown in FIG. 3, a control signal is output from the output circuit 10b to the vertical variable motor 1c and the horizontal variable motor 1d according to the processing result of the CPU 10c. To.

As shown in FIG. 5, the control device 10 according to this embodiment includes an operation control unit 11, a timer unit 12, and a water level prediction unit 13. The functions of each of these units are realized by the CPU 10c executing the process specified by the program stored in the storage unit 10d.

The operation control unit 11 controls the operations of the dehumidifying device 5, the blower fan 2, and the wind direction variable unit 1 in response to various signals input to the input circuit 10a. That is, the operation control unit 11 is a control means that specifically controls the operation of the above-mentioned dehumidifying means. The timer unit 12 measures the elapsed time from a certain point in time. The timekeeping result by the timer unit 12 is used, for example, for the control of the above-mentioned dehumidifying means by the operation control unit 11.

The water level prediction unit 13 predicts the water level of the water stored in the water storage tank 102, that is, the amount of water stored in the water storage tank 102. The water level prediction unit 13 of this embodiment is a water storage amount predicting means for predicting the water storage amount of the water storage tank 102. First, the water level prediction unit 13 calculates the amount of water removed from the indoor air P by the above-mentioned dehumidifying means based on the temperature and humidity of the indoor air P and the dehumidifying capacity and operating time of the above-mentioned dehumidifying means. Then, the water level prediction unit 13 predicts the water level of the water storage tank 102, that is, the water storage amount of the water storage tank 102, from the calculated water amount.

The prediction of the amount of water stored in the water storage tank 102 by the water level prediction unit 13 will be described in more detail. First, the water level prediction unit 13 calculates the absolute humidity of the indoor air P, that is, the amount of water contained in the indoor air P, from the temperature and humidity (relative humidity) of the indoor air P. At this time, as the temperature and humidity of the indoor air P, the detection results of the temperature sensor 3 and the humidity sensor 4 are used.

Next, the water level prediction unit 13 obtains the dehumidifying capacity of the above-mentioned dehumidifying means. The dehumidifying capacity of the above-mentioned dehumidifying means can be obtained from, for example, the performance of the dehumidifying device 5 and the amount of indoor air P passing through the dehumidifying device 5 per unit time. The performance of the dehumidifier 5 is predetermined, for example, from the specifications of the dehumidifier. Therefore, it is conceivable to store the specific value of the performance of the dehumidifying device 5 in the storage unit 10d in advance, for example. Further, the amount of the indoor air P passing through the dehumidifying device 5 per unit time can be obtained from the air volume of the blower fan 2. Information on the air volume of the blower fan 2 may be acquired from, for example, the operation control unit 11.

Subsequently, the water level prediction unit 13 calculates the amount of water per unit time that the above-mentioned dehumidifying means removes from the room air P from the amount of water contained in the room air P and the dehumidifying capacity of the above-mentioned dehumidifying means. Then, the water level prediction unit 13 multiplies the amount of water per unit time removed by the above-mentioned dehumidifying means from the indoor air P by the operating time of the above-mentioned dehumidifying means, and has been used since the dehumidifier started operation. In addition, the so-called theoretical value of the amount of water removed from the indoor air P by the above-mentioned dehumidifying means is calculated. For the operating time of the dehumidifying means described above, for example, the result measured by the timer unit 12 is used.

The water level prediction unit 13 predicts the water level of the water storage tank 102, that is, the water storage amount of the water storage tank 102 by accumulating the amount of water removed by the above-mentioned dehumidifying means calculated as described above. At this time, the integrated value of the water content is reset, for example, by removing the water storage tank 102 from the housing 100 and resetting it each time the water in the water storage tank 102 is discarded.

The operation control unit 11 stops the operation of the dehumidifying means when at least one of the first condition and the second condition described below is satisfied during the operation of the dehumidifying means described above.

First, the first condition is that the water storage amount of the water storage tank 102 detected by the above-mentioned water storage amount detecting means, that is, the float switch 9, is equal to or more than the above-mentioned first water storage amount. As described above, the first water storage amount is the water storage amount for determining that the water storage tank 102 is full. Therefore, when the water storage amount of the water storage tank 102 reaches the first water storage amount described above and the float switch 9 operates, the operation control unit 11 of the control device 10 stops the operation of the dehumidifying device 5 and the blower fan 2.

Next, the second condition is that the water storage amount of the water storage tank 102 predicted by the above-mentioned water storage amount prediction means, that is, the water level prediction unit 13, is equal to or larger than the second water storage amount. The second water storage amount is also preset as the water storage amount for determining that the water storage tank 102 is full, similar to the first water storage amount described above. The first water storage amount and the second water storage amount may be the same value or may be different values. In any case, the first water storage amount and the second water storage amount are set to such an amount that the water does not overflow from the water storage tank 102 even if the condensed water C is stored in the water storage tank 102 up to that amount. To.

According to the dehumidifier configured as described above, even if an abnormality occurs in the float switch 9 which is a water storage amount detecting means and the water storage amount of the water storage tank 102 cannot be detected. When the water storage amount predicted by the water level prediction unit 13 which is the water storage amount prediction means becomes equal to or more than the above-mentioned second water storage amount, the operation of the dehumidifying device 5 can be stopped. Therefore, even if an abnormality occurs in the float switch 9, it is possible to prevent water from overflowing from the water storage tank 102.

Next, an example of the operation of the dehumidifier according to this embodiment will be described with reference to the flow chart of FIG. First, in step S1, when the operation switch 8 is operated and the dehumidifier starts the dehumidifying operation, the operation control unit 11 starts the operation of the dehumidifying means of the blower fan 2 and the dehumidifying device 5.

When the operation of the dehumidifying means is started, in the following step S2, first, the water level predicting unit 13 uses the dehumidifying means to move the indoor air based on the temperature and humidity of the indoor air P and the dehumidifying capacity and operating time of the dehumidifying means. The amount of water removed from P is calculated. Then, the water level prediction unit 13 integrates the amount of water removed by the calculated dehumidifying means, that is, the amount of condensed water C. After step S2, the process proceeds to step S3.

In step S3, the operation control unit 11 determines that the water storage tank 102 is full based on the detection result of the water storage amount detecting means. That is, the operation control unit 11 confirms whether or not the water storage amount of the water storage tank 102 reaches the first water storage amount described above and the float switch 9 operates. When the float switch 9 is operated, the process proceeds to step S5.

In step S5, the operation control unit 11 stops the operation of the dehumidifying means of the blower fan 2 and the dehumidifying device 5. When the process of step S5 is completed, the series of operations is completed.

On the other hand, if the float switch 9 is not operating in step S3, the process proceeds to step S4. In step S3, the operation control unit 11 determines that the water storage tank 102 is full based on the prediction result of the water storage amount predicting means. That is, the operation control unit 11 determines whether or not the predicted value of the water storage amount of the water storage tank 102 reaches the above-mentioned second water storage amount as a result of the water level prediction unit 13 integrating the amount of condensed water C in step S2. Confirm. If the predicted value of the water storage amount of the water storage tank 102 does not reach the above-mentioned second water storage amount, the process returns to step S2. On the other hand, when the predicted value of the water storage amount of the water storage tank 102 reaches the above-mentioned second water storage amount, the process proceeds to step S5.

Embodiment 2.
7 and 8 relate to the second embodiment of the present invention. FIG. 7 is a block diagram showing a functional configuration of a control device included in the dehumidifier. FIG. 8 is a flow chart showing an operation example of the dehumidifier.

In the second embodiment described here, it is possible to determine that an abnormality has occurred in the water storage amount detecting means in the configuration of the first embodiment described above. Hereinafter, the dehumidifier according to the second embodiment will be described focusing on the differences from the first embodiment. The configuration in which the description is omitted is basically the same as that in the first embodiment.

In the dehumidifier according to this embodiment, first, the above-mentioned second water storage amount is set to a value larger than the above-mentioned first water storage amount. Since the water storage amount predicted by the water level prediction unit 13 is only a predicted value, the water storage amount detected by the float switch 9 is more accurate. Therefore, by making the second water storage amount larger than the first water storage amount, the float switch 9 indicates that the water storage amount of the water storage tank 102 is equal to or more than the first water storage amount while the float switch 9 is normal. When is detected, the operation control unit 11 determines that the tank is full and stops the operation of the dehumidifying device 5 and the like.

Then, when an abnormality occurs in the float switch 9 and the float switch 9 does not operate even if the water storage amount of the water storage tank 102 reaches the first water storage amount, the water storage amount predicted by the water level prediction unit 13 becomes the first. When the water storage amount of 2 is reached, the operation control unit 11 can determine that the tank is full and stop the operation of the dehumidifying device 5 and the like. In this way, the above-mentioned second water storage amount is set to a value larger than the above-mentioned first water storage amount, and the full water detection by the float switch 9 is prioritized over the full water determination by the predicted value of the water level prediction unit 13. , It is possible to suppress the occurrence of variation in the amount of water that can be stored in the water storage tank 102.

In the dehumidifier according to this embodiment, as shown in FIG. 7, the control device 10 further includes a float abnormality determination unit 14 in addition to the operation control unit 11, the timer unit 12, and the water level prediction unit 13. .. The float abnormality determining unit 14 is an abnormality determining means for determining that an abnormality has occurred in the float switch 9 which is the above-mentioned water storage amount detecting means. The float abnormality determination unit 14 determines that an abnormality has occurred in the water storage amount detecting means by using the detection result by the above-mentioned water storage amount detecting means and the prediction result by the above-mentioned water storage amount predicting means.

More specifically, the float abnormality determination unit 14 is predicted by the water level prediction unit 13 in a situation where the float switch 9 does not operate, that is, the operation signal of the switch is not input from the float switch 9 to the input circuit 10a. When the amount of stored water reaches the above-mentioned second amount of stored water, it is determined that the float switch 9 is abnormal.

As described above, here, the above-mentioned second water storage amount is set to a value larger than the above-mentioned first water storage amount. Therefore, when the water storage amount predicted by the water level prediction unit 13 is equal to or more than the above-mentioned second water storage amount, and if the prediction by the water level prediction unit 13 is correct, the water storage amount of the water storage tank 102 is equal to or more than the above-mentioned first water storage amount. But it should be. Nevertheless, since the float switch 9 is not operating, in this case, the float abnormality determination unit 14 determines that some abnormality has occurred in the float switch 9.

Here, the state in which the operation signal of the switch is not output from the float switch 9 means that the water storage amount detecting means detects that the water storage amount of the water storage tank 102 is less than the above-mentioned first water storage amount. It can be said that there is. Therefore, in the float abnormality determination unit 14, which is an abnormality determination means, the water storage amount of the water storage tank 102 predicted by the above-mentioned water storage amount prediction means is equal to or more than the above-mentioned second water storage amount, and the above-mentioned water storage amount detection means. When the water storage amount of the water storage tank 102 detected by is less than the first water storage amount described above, it is determined that the water storage amount detecting means described above is abnormal.

When the float abnormality determination unit 14 determines that the float switch 9 is abnormal, for example, a float abnormality signal is output from the output circuit 10b to the display unit 7. Then, the display unit 7 displays that an abnormality has occurred in the float.

Next, an example of the operation of the dehumidifier according to this embodiment will be described with reference to the flow chart of FIG. Steps S1 to S5 in the flow chart of FIG. 8 are the same as steps S1 to S5 of FIG. 6, respectively. For this reason, the description of these steps here is omitted. In the flow chart of FIG. 8 according to this embodiment, when the predicted value of the water storage amount of the water storage tank 102 reaches the above-mentioned second water storage amount in step S4, the process proceeds to step S6.

In step S6, the float abnormality determination unit 14 determines that the float switch 9 is abnormal. Then, after step S6, the process proceeds to step S5, and the operation control unit 11 stops the operation of the dehumidifying means of the blower fan 2 and the dehumidifying device 5. When the process of step S5 is completed, the series of operations is completed.

Even in the dehumidifier configured as described above, the same effect as that of the first embodiment can be obtained. Further, in the dehumidifier of this embodiment, the float abnormality determination unit 14 causes an abnormality in the water storage amount detecting means by using the detection result by the above-mentioned water storage amount detecting means and the prediction result by the above-mentioned water storage amount predicting means. Judgment of what has been done. Then, when it is determined that an abnormality has occurred in the water storage amount detecting means, it is possible to display the fact on the display unit 7 or the like and notify the user. Therefore, it is possible to urge the user to take measures such as checking, inspecting, and arranging repairs for the float switch 9.
