However, in the above-described conventional air conditioner, since the dehumidification operation is controlled based on the detected temperature, there is a problem that the dehumidification operation is performed and the waste dehumidification operation is performed even if the humidity is low and the clothes are easily dried.

The present invention has been made in order to solve the problems as described above, and an object of the invention is to provide an air conditioner which controls operation according to environmental conditions and improves energy saving performance.

In order to solve this problem, an air conditioner may be provided, comprising: a dehumidifying means for removing moisture contained in the air; and a blowing means for drawing in the indoor air and then blowing the air into the room to pass the air through the dehumidifying means. The dry air; the humidity detecting means detects the indoor humidity; the temperature detecting means detects the indoor temperature; and the control means controls the dehumidifying means and the air blowing means according to the temperature detecting means and/or the detecting result of the humidity detecting means The control means is operable to perform the air blowing operation only by operating the air blowing means for a predetermined period of time before the dehumidifying means is operated to perform the dehumidifying operation.

According to the present invention, it is determined that the condition in which the air-dried object is dried is also determined based on the detection result of the environmental condition, and after the air blowing operation is performed in the first half of the clothes drying operation, the dehumidifying operation is completed in the latter half of the operation. Therefore, power consumption can be suppressed as compared with the clothes drying operation according to the general dehumidification operation.

In addition, when it is determined that the air blowing operation cannot be sufficiently dried, the drying operation is performed, and the drying target is dried at the end of the operation regardless of the environmental conditions. Will not dry.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view showing the appearance of an air conditioner according to an embodiment. Fig. 2 is a schematic configuration view showing the inside of an air conditioner according to an embodiment. Fig. 3 is a schematic perspective view showing, in an enlarged manner, a wind direction changing means of Fig. 1. Fig. 4 is a view showing the detection range of the infrared sensor of the air conditioner of the embodiment.

As shown in Fig. 1, the air conditioner of the present embodiment is composed of the following members, and the air conditioner housing 100 can be constructed independently; the suction port 101 is used for the air conditioner housing 100. The indoor air A is taken in; the water storage tank 102 stores moisture removed by the air taken in from the suction port 101; and the air discharge port 103 discharges the dry air B from which the moisture is removed from the air conditioner casing 100.

The wind direction changing means 1 for changing the wind direction of the dry air B is provided in the exhaust port 103. The wind direction changing means 1 is composed of a vertical louver 1a that changes the wind direction in the vertical direction and a horizontal louver 1b that changes the wind direction in the horizontal direction.

Further, the water storage tank 102 is detachably attached to the air conditioner housing 100.

Next, as shown in FIG. 2, the air conditioner casing 100 has a blower fan 2, and generates a series of airflows from the exhaust port 103 after the indoor air A is taken in from the intake port 101. The temperature sensor 3 (temperature detecting means) detects the temperature of the indoor air A sucked from the suction port 101; the humidity sensor 4 (humidity detecting means) detects the humidity of the indoor air A; the dehumidification means 5, the moisture contained in the indoor air A is removed to generate dry air B; the longitudinal variable motor 1c is such that the longitudinal louver 1a is variable in the vertical direction; and the laterally variable motor 1d is such that the horizontal louver 1b is horizontal The infrared sensor 6 is a surface temperature detecting means; a display unit (not shown) displays various kinds of information; and a control circuit 7 (control means).

These various sensors are connected to the control circuit 7 in such a manner that a detection signal can be input to the control circuit 7. Moreover, the dehumidification means 5 or the display part or various The motor is coupled to the control circuit 7 in a manner controllable by the control means based on the user's operational input or input values of the various sensors.

Next, the dehumidifying means 5 may be any one that removes moisture from the air and causes it to coagulate. For example, as the most generalizer, a method of constituting a heat pump circuit and condensing moisture in the air in the evaporator or using heat exchange is used. The device is a desiccant method in which the fraction in the air removed by the adsorbent is condensed.

On the other hand, the moisture of the indoor air A is removed by the dehumidification means 5 as condensed water, and is stored in the water storage tank 102.

Next, as shown in Fig. 3, the longitudinal louver 1a has a rectangular opening extending in the width direction of the air conditioner housing 100, and is configured to be substantially vertical with the rotation axis of the longitudinal variable motor 1c as an axis. The direction is variable.

The horizontal louver 1b is disposed at equal intervals in the longitudinal louver 1a, and is configured to be axially variable in a horizontal direction at a depth opposite to the opening of the longitudinal louver 1a, and is interlocked with the driving of the lateral variable motor 1d described above. .

The infrared sensor 6 is attached to one side of the horizontal louver 1b disposed in the center of the longitudinal louver 1a.

Therefore, the detection range of the surface temperature of the object to be dried or the like by the infrared sensor 6 is substantially the same as the direction of the dry air B which is variable by the wind direction changing means 1. In other words, the infrared sensor 6 can detect the surface temperature of the entire region within the range in which the wind direction changing means 1 can supply air.

Next, the infrared sensor 6 is made of, for example, a thermoelectromotive force effect, and is composed of the following members (see FIGS. 2 and 3), and infrared rays. The line absorbing film 6a receives heat radiation (infrared rays) generated from the surface of the predetermined region, and the resistor 6b detects the temperature of the infrared absorbing film 6a.

The infrared sensor 6 is a temperature (warm junction) of the heat sensitive portion of the infrared absorbing film 6a which is heated by absorption of heat radiation, and a temperature (cold junction) of the infrared absorbing film 6a detected by the resistor 6b. The difference is converted into an electrical signal such as a voltage, and then input to a control circuit 7 to be described later. From the magnitude of the electrical signal, the surface temperature of the predetermined region can be discriminated.

Here, a method of detecting the surface temperature of a predetermined region will be described using FIG.

As shown in FIG. 4, in the case where the entire area detectable by the infrared sensor 6 is the full scan range 200, the full scan range 200 has a planar shape which is enlarged in the horizontal direction (horizontal direction) and the vertical direction (vertical direction). range.

The infrared sensor 6 is controlled to detect the surface temperature in each of the plurality of divided regions 201 in the horizontal direction and the vertical direction in the full scan range 200. Thereby, a detailed temperature map can be produced for a wide range of areas.

Next, when the dehumidification mode is selected from the switching operation of the operation unit (not shown), the control circuit 7 drives the wind direction changing means 1 to blow air from the exhaust port 103, and drives the fan motor 2a to supply the blower fan. 2 Rotation, also drives the dehumidification means 5 to make the indoor humidity the optimum humidity.

Moreover, the control circuit 7 drives the longitudinal variable motor 1c and the lateral variable motor 1d of the wind direction changing means 1 to blow air toward the desired area of the room. Thereby, the indoor air A is taken into the air conditioner housing 100 from the suction port 101, and is inspected by the temperature sensor 3 and the humidity sensor 4, respectively. After the temperature and humidity in the room are measured, the dehumidification means 5 dehumidifies and becomes the dry air B, and is then blown out from the exhaust port 103 into the room.

Further, when the control circuit 7 starts the operation in the dry mode in which the laundry of the object to be dried is detected, as described above, the wind direction changing means 1 is driven to blow the air from the exhaust port 103, and then the fan motor 2a is driven to The blower fan 2 rotates and also drives the dehumidification means 5.

Then, the control circuit 7 reads the indoor humidity from the indoor air A taken in the air conditioner housing 100 via the humidity sensor 4, and determines whether the humidity is higher than a predetermined humidity.

The control circuit 7 controls the fan motor 2a and the wind direction changing means 1 to maximize the dehumidification performance of the dehumidification means 5 when the indoor humidity is higher than the predetermined humidity and until the indoor humidity reaches a predetermined humidity.

Then, the control circuit 7 uses the infrared ray sensor 6, the arrangement range of the specific washing material by the control, and controls the longitudinal variable motor 1c and the drying air B to be in the range when the indoor humidity is lowered to a predetermined humidity. The laterally variable motor 1d has the louvers 1a, 1b oriented in the direction of the laundry. The predetermined humidity is set in advance to the humidity set by the indoor temperature, and is set as the data in the control circuit 7.

Next, a control circuit 7 in the case of selecting a so-called "clothing-drying eco-drying mode" in which the dehumidification operation and the air supply only air supply operation are combined and the drying of the object to be dried is selected according to the detection result of the environmental conditions will be described. The actions of each department.

Fig. 5 is a flow chart showing the operation in the drying mode of the air conditioner of the embodiment. In addition, regarding the operation of "general dehumidification operation", Because it has been explained, it is omitted.

The control circuit 7 of the air conditioner detects the dry eco-drying mode of the clothes, and starts measuring the total operation time T1 (S0) from the start of the operation, and drives the wind direction changing means 1 so that the air outlet can be driven. The air is blown at 103, and the fan motor 2a is driven to rotate the blower fan 2 to start air supply (S1). Further, at this stage, the dehumidification operation was not performed.

At this time, the control circuit 7 is vaporized by the air blown by the wet clothes, and thus becomes lower than the surrounding temperature. By detecting the position where the temperature is low by the infrared ray sensor 6, the range in which the clothes of the dried object are located is detected (S2).

Next, the step of measuring the temperature RT and the humidity RH1 of the indoor air A is performed.

First, the control circuit 7 starts counting using a timer that detects the predetermined time A (limited time) of the temperature RT and the humidity RH1 (S3). Then, the indoor air A sucked from the suction port 101 to the inside of the air conditioner housing 100 by the air blower 2 is detected by the temperature sensor 3 and the humidity sensor 4, respectively, and the temperature RT and the humidity RH1 are detected (S4). .

The predetermined time A is, for example, a reference time for determining the air blowing time based on the calculated air blowing time Ts in consideration of the humidity condition and the temperature condition. (The decision on the air supply time Ts is described in 0027~0028).

Next, the control circuit 7 reads the humidity RH1 of the detected indoor air A and compares it with the predetermined humidity. The predetermined humidity is, for example, a humidity at which a state in which the humidity is 80% or more is high.

When the humidity RH1 is lower than the predetermined humidity, the process proceeds to S6, and when the humidity RH1 is higher than the predetermined humidity, the process proceeds to S11, and the dehumidification operation is started (S5).

Then, the control circuit 7 reads the temperature RT of the detected indoor air A and compares it with the predetermined temperature. The predetermined humidity is, for example, a temperature at which a state of 15 ° C or lower is detected.

When the temperature RT is higher than the predetermined temperature, the process proceeds to S7, and when the temperature RT is lower than the predetermined temperature, the process proceeds to S11, and the dehumidification operation is started (S6).

Since the state of the indoor air A in the case of moving from S6 to S7 is a state in which the humidity and the temperature are relatively low, it can be said that the wet clothes are easily dried.

Further, in the state where S5 and S6 are moved to S11, it is not possible to sufficiently dry the air. In other words, it is used to control the movement to the dehumidification operation without performing the air blowing operation, and the dried object does not become undried.

Next, the control circuit 7 performs control for detecting the maximum value RHM of the humidity in the predetermined time A when the humidity RH1 is lower than the predetermined humidity and the temperature RT is higher than the predetermined temperature, and moves to S8 (S7). Then, the control circuit 7 shifts to S9 when the maximum value RHM of the humidity in the predetermined time A is detected, and moves to S4 when the maximum value RHM of the humidity is not detected (S8).

Here, the method of detecting the maximum value RHM of the humidity may be the maximum humidity of the humidity RH1 detected in the predetermined time A as the maximum value RHM of the humidity, or the humidity RH1 may be changed from the rising to the falling. The humidity RHM is taken as the maximum value RHM of the humidity.

Then, the control circuit 7 calculates the remaining air blowing time Ts based on the detected maximum value RHM of the humidity, and shifts to S10 (S9). Here, the blowing time Ts is set to the maximum value of the humidity RHM time. Therefore, that is The high humidity can also shorten the dehumidification operation time, and the energy saving effect can be obtained.

Then, the control circuit 7 continues the air blowing operation between the remaining air blowing time Ts set as described above, and then proceeds to S7 to end the air blowing only operation (S10).

Next, the control circuit 7 starts the dehumidifying operation, moves to S11, operates the blower fan 2 and the dehumidifying means 5, and starts measuring the dehumidifying operation time T2 from the dehumidifying operation, and proceeds to S13 (S12).

Therefore, the indoor air A is taken into the air conditioner casing 100 from the suction port 101 by the rotation of the air fan 2, and the dry air B is continuously blown out from the exhaust port 103. At this time, the control circuit 7 reads in the indoor temperature detected by the temperature sensor 3, and continues to read in the indoor humidity detected by the humidity sensor 4.

Then, the control circuit 7 determines whether or not the dehumidification operation time T2 from the dehumidification operation has elapsed for 30 minutes, and if the dehumidification operation time T exceeds 30 minutes, the process proceeds to S14 (S13).

Next, the control circuit 7 determines whether or not the humidity RH1 of the indoor air A is 50% or less (S14). When the humidity RH1 of the indoor air A is 50% or less, the process proceeds to S15, and when the humidity RH1 of the indoor air A exceeds 50%, the process proceeds to S19.

Then, the control circuit 7 determines in S19 whether or not the total operation time T1 from the start of the operation exceeds the limit time of the predetermined operation. When the dehumidification operation time T has not exceeded 12 hours, the process proceeds to S14, and when the dehumidification operation time T exceeds 12 hours, the process proceeds to S21, and the forced end is performed. Reason.

Then, the control circuit 7 calculates the remaining time TL of the dehumidification operation from the dehumidification operation time T and the room temperature RT from the start of the dehumidification operation (S15), then proceeds to S16, displays the remaining time TL on the display unit, and moves to S17.

Then, the control circuit 7 determines whether or not the humidity RH1 of the indoor air A is 50% or less (S17). When the humidity RH1 of the indoor air A is 50% or less, the process proceeds to S18, and after the additional dehumidification operation is performed, the operation is terminated. When the humidity RH1 of the indoor air A exceeds 50%, the process moves to S20.

Next, the control circuit 7 determines in S20 whether or not the total operation time T1 from the start of the operation exceeds the limit time of the predetermined operation. When the dehumidification operation time T has not exceeded 12 hours, the process proceeds to S16, and when the dehumidification operation time T exceeds 12 hours, the process proceeds to S21, and the forced end process is performed.

As described above, since the respective units are operated by the control circuit 7, the air blowing operation for supplying only the air is combined and operated before the dehumidifying operation. Therefore, the drying operation of the clothes to be dried can be performed while suppressing the power consumption.

In particular, when the conditions under which the air-dried material is dried are determined based on the detection result of the environmental conditions, the air blowing operation is performed in the first half of the drying operation of the clothes, and the dehumidifying operation is completed in the latter half of the operation. Therefore, power consumption can be suppressed as compared with the clothes drying operation by the general dehumidification operation.

In addition, when the temperature or humidity of the indoor air is detected and the condition that the air supply cannot be sufficiently dried (S5, S6) is determined, the operation of stopping the air supply is performed and the control of the dehumidification operation is performed, so that regardless of the environmental conditions, The dried material is dried at the end of the operation so as not to be undried.

Moreover, since the time of the air blowing operation is determined according to the humidity of the indoor air, it is possible to perform efficient air blowing control suitable for the humidity of the indoor air.

An example of the numerical value which is the basis of the control used in the above embodiment is not limited to the above numerical value. Further, it is also possible to configure these numerical values to be appropriately changed in accordance with the environment in which the air conditioner is used or the preference of the user.
