detailed description

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

Fig. 1 is an external perspective view showing an air conditioner according to an embodiment. Fig. 2 is a schematic configuration diagram showing the inside of the air conditioner according to the embodiment. Fig. 3 is an enlarged schematic perspective view showing an airflow direction changing member in Fig. 1 . Fig. 4 is a schematic diagram showing the detection range of the infrared sensor of the air conditioner according to the embodiment.

As shown in FIG. 1 , the air conditioner of this embodiment is composed of the following components: an air conditioner frame 100 capable of standing on its own; a suction port 101 for taking room air A into the air conditioner frame 100; The water storage tank 102 stores moisture removed from the air taken into the suction port 101 , and the exhaust port 103 discharges the dry air B from which the moisture has been removed from the air conditioner housing 100 into the room.

The wind direction variable member 1 for changing the wind direction of the dry air B is provided on the exhaust port 103 . The wind direction variable member 1 is composed of a vertical swing vane 1a for changing the vertical wind direction and a horizontal swing vane 1b for changing the horizontal wind direction.

Moreover, the water storage tank 102 is detachably attached to the air conditioner housing|casing 100. As shown in FIG.

Hereinafter, as shown in FIG. 2 , inside the air conditioner frame body 100 there is: a blower fan 2 that generates a series of airflows that suck indoor air A from the suction port 101 and discharge dry air B from the exhaust port 103; The fan motor 2a rotates the blower fan 2; the temperature sensor 3 (temperature detection component) detects the temperature of the indoor air A sucked from the suction port 101; the humidity sensor 4 (humidity detection component) detects the humidity of the indoor air A; The dehumidification component 5 removes the moisture contained in the indoor air A and generates dry air B; the vertical variable motor 1c makes the vertical swing blade 1a change in the vertical direction; the horizontal variable motor 1d makes the horizontal swing blade 1b move in the horizontal direction variable; an infrared sensor 6 as surface temperature detection means; a display unit (not shown) that displays various information; and a control circuit 7 (control means).

These various sensors are connected to the control circuit 7 so that their detection signals can be input to the control circuit 7 . In addition, the dehumidifier 5, the display unit, and various motors are connected to the control circuit 7 so that they can be controlled by the control means based on user's operation input and input values of various sensors.

Secondly, it is enough that the dehumidifying member 5 can remove the moisture in the air and condense it. For example, as the most common component, a heat pump circuit can be used to condense the moisture in the air in the evaporator, so that the air removed by the adsorbent The desiccant method in which the moisture is condensed in the heat exchanger, etc.

Furthermore, the moisture removed from the indoor air A by the dehumidifying means 5 is stored in the water storage tank 102 as condensed water C.

Hereinafter, as shown in FIG. 3 , the vertical swing blade 1 a has a rectangular opening extending in the width direction of the air conditioner housing 100 , and is approximately variable in the vertical direction with the rotation axis of the above-mentioned vertical variable motor 1 c as an axis. to constitute.

The horizontal swing blade 1b is configured to be arranged at equal intervals in the vertical swing blade 1a, and can be variably supported in the horizontal direction on the inner side of the opposite side of the opening of the vertical swing blade 1a. Make linkage.

The infrared sensor 6 is attached to one surface of the horizontal swing blade 1b disposed approximately in the center of the vertical swing blade 1a.

Accordingly, the detection range of the surface temperature of the object to be dried by the infrared sensor 6 is substantially the same as the direction of the dry air B which is changed by the wind direction variable member 1 . That is, the infrared sensor 6 can detect the surface temperature of the entire area within the range where the wind direction variable member 1 can blow air.

Next, the infrared sensor 6 is, for example, a sensor utilizing the thermoelectromotive force effect, and is composed of an infrared absorbing film 6a that receives thermal radiation (infrared rays) emitted from the surface of a predetermined area, and a thermistor 6b that detects the temperature of the infrared absorbing film 6a. (Refer to Figure 2, Figure 3).

The infrared sensor 6 converts the difference between the temperature (hot junction) of the heat-sensitive part of the infrared absorption film 6a heated by absorbing thermal radiation and the temperature (cold junction) of the infrared absorption film 6a detected by the thermistor 6b into a voltage. etc., and input to the control circuit 7 described later. The surface temperature of a predetermined area can be determined based on the magnitude of the electric signal.

Here, the detection method of the surface temperature of a predetermined area is demonstrated using FIG. 4. FIG. As shown in FIG. 4 , when the entire area detectable by the infrared sensor 6 is the full scan range 200 , the full scan range 200 is a planar range extending laterally (horizontally) and vertically (vertically).

The infrared sensor 6 is controlled to detect the surface temperature for each of the divided regions 201 that divide the full scanning range 200 into a plurality of horizontal and vertical directions. Thereby, a detailed temperature map can be created for a wide area.

Next, when the above-mentioned control circuit 7 detects that the dehumidification mode has been selected through the switch operation of the operation part (not shown), the wind direction variable member 1 is driven to blow air from the exhaust port 103, and the fan motor 2a is driven to blow air. The wind fan 2 rotates to drive the dehumidification member 5 so that the indoor humidity becomes the optimum humidity.

In addition, the control circuit 7 drives the vertically variable motor 1c and the horizontally variable motor 1d of the wind direction variable member 1 to blow air in the direction of a desired area in the room. Thus, the indoor air A is taken into the air conditioner housing 100 from the suction port 101, and after the temperature and humidity in the room are detected by the temperature sensor 3 and the humidity sensor 4 respectively, it is dehumidified by the dehumidification member 5 to become dry air B, from which The exhaust port 103 blows out into the room.

In addition, when the control circuit 7 detects that the operation of the drying mode of the object to be dried, that is, the laundry, is started, the wind direction variable member 1 is driven as described above to blow air from the exhaust port 103, and the fan motor 2a is driven to make the blower fan 2 to rotate and drive the dehumidification member 5.

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

When the indoor humidity is higher than the specified humidity, the control circuit 7 controls the fan motor 2a and the wind direction variable member 1 to maximize the dehumidification capacity of the dehumidifying member 5 until the indoor humidity reaches the specified humidity.

And when the control circuit 7 lowers the indoor humidity to a predetermined humidity through this control, it uses the infrared sensor 6 to determine the arrangement range of the laundry, and controls the vertical variable motor 1c and the horizontal variable motor 1c so that the dry air B reaches the range. The inverter 1d directs the swing blades 1a, 1b toward the laundry. The predetermined humidity is humidity set in advance based on the indoor temperature, and is set in the control circuit 7 as data.

In the following, the operation of the control circuit 7 and various parts when the so-called "clothes drying energy-saving airing mode" is selected will be described using FIG. 5. The so-called "clothes drying energy-saving airing mode" combines dehumidification Drying of the object to be dried is carried out in the air blowing operation and the air blowing operation only.

Fig. 5 is a flowchart showing operations in the drying mode of the air conditioner according to the embodiment. In addition, the operation about the "normal dehumidification operation" is omitted since it has already been described above.

The control circuit 7 of the air conditioner detects that the clothes drying and energy-saving airing mode is selected, and when the operation starts, the measurement (S0) of the total operation time T1 from the start of the operation is started, and the wind direction variable member 1 is driven to blow air from the air outlet 103. To blow air, the fan motor 2a is driven to rotate the blower fan 2 to start blowing air (S1). In addition, in this stage, dehumidification operation is not performed.

At this time, the moisture of the wet laundry is vaporized by the blown air, and the temperature becomes lower than the ambient temperature. The position where the temperature is low is detected by the infrared sensor 6 , whereby the control circuit 7 detects the range where the clothes to be dried are ( S2 ).

Then, it progresses to the process of measuring the temperature RT and humidity RH1 of room air A.

First, the control circuit 7 starts a timer for measuring a predetermined time A (limited time) for detecting the temperature RT and the humidity RH1 ( S3 ). Then, temperature sensor 3 and humidity sensor 4 detect temperature RT and humidity RH1 of room air A sucked into air conditioner housing 100 from suction port 101 by blower fan 2 ( S4 ).

The predetermined time A serves as a reference time for determining the air blowing time Ts obtained, for example, by calculation for determining the air blowing time including humidity conditions and temperature conditions.

Then, the control circuit 7 reads the detected humidity RH1 of the room air A, and compares it with a predetermined humidity. The predetermined humidity means, for example, when a high humidity state of 80% or more is detected.

If the humidity RH1 is lower than the predetermined humidity, the process proceeds to S6 , and if the humidity RH1 is higher than the predetermined humidity, the process proceeds to S11 to start the dehumidification operation ( S5 ).

Then, the control circuit 7 reads the detected temperature RT of the room air A, and compares it with a predetermined temperature.

The predetermined temperature means, for example, when a state of 15° C. or lower is detected.

If the temperature RT is higher than the predetermined temperature, the process proceeds to S7, and if the temperature RT is lower than the predetermined temperature, the process proceeds to S11 to start the dehumidification operation (S6).

The state of the indoor air A in the transition from S6 to S7 is a state of relatively low humidity and high temperature, so it can be said that wet clothes are easily dried.

In addition, the state transitioning to S11 in S5 and S6 is a condition that sufficient drying cannot be achieved by blowing air. That is, it is a judgment that the air blowing operation is not performed, and the dehumidification operation is performed directly, and the control is performed so that the object to be dried does not become undried.

Then, when the humidity RH1 is lower than the predetermined humidity and the temperature RT is higher than the predetermined temperature, the control circuit 7 executes control to detect the maximum value RHM of the humidity within the predetermined time A, and the process proceeds to S8 ( S7 ). Then, the control circuit 7 proceeds to S9 when the maximum value RHM of the humidity is detected within the predetermined time A, and proceeds to S3 when the maximum value RHM of the humidity is not detected ( S8 ).

Here, the detection method of the maximum value RHM of the humidity may also be to use the maximum humidity as the maximum value RHM of the humidity within the humidity RH1 detected within the predetermined time A, and may also change the humidity value when the humidity RH1 changes from rising to falling. RHM as the maximum RHM of humidity.

Then, the control circuit 7 calculates the remaining air blowing time Ts based on the detected maximum value RHM of the humidity, and proceeds to S10 ( S9 ). Here, the larger the maximum value RHM of the humidity is, the longer the air blowing time Ts is set. Thereby, even if the humidity is high, the time of the dehumidification operation can be shortened, and a more energy-saving effect can be obtained.

Then, the control circuit 7 continues the air blowing operation during the remaining air blowing time Ts set as described above, and then proceeds to S11 to end the air blowing only operation ( S10 ).

Then, the control circuit 7 starts the dehumidification operation, proceeds to S12, activates the blower fan 2 and the dehumidification means 5, starts measuring the dehumidification operation time T2 from the start of the dehumidification operation, and proceeds to S13 (S12).

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

Then, the control circuit 7 determines whether or not 30 minutes have elapsed since the dehumidification operation time T2 from the start of the dehumidification operation, and when the dehumidification operation time T2 exceeds 30 minutes, the process proceeds to S14 ( S13 ).

Then, the control circuit 7 determines whether the humidity RH1 of the room air A is 50% or less (S14). When the humidity RH1 of the room air A is 50% or less, the process goes to S15, and when the humidity RH1 of the room air A exceeds 50%, the process goes to S19.

Then, the control circuit 7 judges in S19 whether or not the total operation time T1 from the start of the operation exceeds 12 hours, which is a predetermined limit time (limit time) of the operation. If the total operation time T1 does not exceed 12 hours, the process goes to S14, and if the total operation time T1 exceeds 12 hours, the process goes to S21, and the forced end process is performed.

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

Then, the control circuit 7 determines whether the humidity RH1 of the room air A is 50% or less (S17). If the humidity RH1 of the room air A is 50% or less, the process proceeds to S18, and after an additional dehumidification operation is performed, the operation is terminated. When the humidity RH1 of the room air A exceeds 50%, it transfers to S20.

Then, the control circuit 7 judges in S20 whether or not the total operation time T1 from the start of the operation exceeds 12 hours, which is a predetermined limit time (limit time) of the operation. If the total operation time T1 is not more than 12 hours, the process goes to S16, and if the total operation time T1 exceeds 12 hours, the process goes to S21, and the processing is forced to end.

As described above, each part is operated by the control circuit 7, and the air blowing operation of only blowing air is combined with the air blowing operation before the dehumidification operation, so that the drying operation of the clothes to be dried, that is, the clothes to be dried, can be performed while suppressing power consumption.

In particular, if it is judged from the detection result of the environmental conditions that the object to be dried can be dried even with the blower, the blower operation is performed in the first half of the clothes drying operation, and the dehumidification operation is performed in the second half of the operation. And done. Thereby, power consumption can be suppressed compared with the clothes drying operation performed by normal dehumidification operation.

In addition, when the temperature or humidity of the indoor air is detected, and it is judged that the air blowing cannot sufficiently dry the condition (S5, S6), the operation of only the air blowing is stopped and the control is performed to the dehumidification operation, thereby regardless of the environmental conditions. In any case, the object to be dried can be dried at the end of the operation so that the object to be dried will not be undried.

In addition, since the ventilation operation time is determined based on the humidity of the room air, efficient ventilation control suitable for the humidity condition of the room air can be performed.

The numerical values used as the control references in the above embodiments are merely examples, and the present invention is not limited to the above numerical values. In addition, these reference numerical values can also be set and changed appropriately according to the environment in which the air conditioner is used and user's preference.
