When 7 winds are emitted, they are discharged as warm air, and s from the warm air outlet 1 Ob only blows out the guar @ discharge. In the normal thirst operation, the second wind is treated as The cold air outlet 10 is blown out. In the middle of the operation, the cold air and the warm air are simultaneously blown from the front. The sixth figure shows the block diagram of the dehumidifier w and the service system. The dehumidifier 1 is composed of a material such as a computer. The control unit 30 is connected to the input side of the control unit 30 at 2l48-9858-PF; Ahddub 9 1374243 The temperature detecting means 3 for detecting the indoor temperature and the humidity detecting means 32 for detecting the indoor humidity perform various arithmetic processing in accordance with the operation signal, the indoor temperature and the humidity of the operation unit 12a. Further, the temperature detecting means 31 And the humidity detecting means 3 2 is attached to the appropriate part of the quenching machine 1 Taiji, Shimamu, and the micro-body.

The louver 13 is rotated by the louver drive motor 34 in the longitudinal direction thereof, and is rotated in the range shown in Figs. 8 and 9. The air blowing range can be arbitrarily changed. Moreover, the example of Fig. 8 is to supply the air. The range is wide angle (110 sounds _ month), and the example of 苐9 is often oriented toward the front (6 degrees). As described above, by changing the air supply range by rotating the louver 13, the dehumidification and the direction of the wind can be blown out.犲红立 + 7 Change direction driving mode may be arbitrarily

Select 'can be fixed in the direction of the 定 A A ,, or, in a certain range of angles, periodically in the complex D - -, when the one chain is = person and the control is made between the upper and lower positions of the set | When the car is used, it can effectively mix the indoor air and improve the moisture absorption. When the clothes are dry, the air supply range can be evenly widened (1), and the A, ^.., The second rolling is sent out to a wide range of clothes to be dried, so that the dry taste can be shortened. „ ' Also, when the ground is dried, the air supply range is forward/ϊρ, (6 degrees), The dehumidified air is sent to the ground, so the drying time can be shortened. 2148-9858-PF; Ahddub 10 丄: Next, the main purpose of the dehumidifier 1 of the present embodiment will be described, in particular, the monthly b effectively suppresses the growth of mold which can accumulate water such as a cold room. The anti-mold operation operation. The first diagram is a flowchart in the operation control example. The operation will be described with reference to these drawings. When the insertion plug la (see Fig. 2) of the field dehumidifier 1 is inserted into the socket, the operation will be performed. Start 'temperature detector 31 and the humidity detecting means 32 detect the internal temperature and humidity, and the control unit 30 takes in the detected indoor/Ridue and humidity. The control unit 3 determines the operation switch of the operation unit 1 (not If it is determined whether or not the operation switch is cut (S13), it is determined that the operation switch is cut (S14). For example, when the operation mode other than the mold proof operation is set (S15), the operation mode is performed. Processing (S16) ^When the operation mode is sighed in the mold proof operation mode (S17), it is determined whether the indoor temperature is dead (S1 8) *To the internal temperature> At 20 °C, the minimum operation time is set to 4 hours. When the indoor temperature is <2〇.〇, the minimum operation time is set to 6 hours, and the mold-proof operation (S2〇) is started. The cold air by the evaporator 2, the warm air by the condenser 或, or both of them are implemented. The control unit 30 determines whether the humidity is <5〇% (S21), when the humidity is >5 〇%, set the swing angle of the louver 13 to a wide angle (JJ , degree, refer to Fig. 8 and drive the louver The motor 34 is driven (S22). When the humidity side is set, the louver 13 is driven to the front (60 degrees, see Fig. 9) to drive the louver drive motor 34 (S23). Next, the control unit 30 determines that the arrival is reached. Elapsed time after humidity less than 5〇%>4 hours, and elapsed time after start of operation> 2148-9858-PF of minimum running time; Ahddub 11 Two conditions (S21) (S24), when the condition is not satisfied, return to the above-mentioned repeated processing (S21) to (S24), and when the condition is satisfied, stop the operation. The 11th figure indicates the timing of how the humidity of the processing is changed by the 帛10 map. Figure. In order to prevent the mold in the high-humidity space such as the bathroom, when the above-mentioned mold-proof operation is performed, after the person baths, the relative humidity of the bathroom and the clothes-free room may exceed 80%. When the operation starts in this state, The louver W is swayed at a wide angle (110 degrees) (reciprocating motion) (Fig. 8), and the indoor air is stirred efficiently (4). At the same time, the dehumidified air is sent to the ceiling or the J surface to remove the ceiling or wall. Water droplets on it. Moreover, as time passes, the humidity will decrease. When the relative humidity is less than 50%, the louver 13 is swung forward (60 degrees) (Fig. 9), and the air supply range is switched to the range close to the ground to perform ground drying. . The state where the humidity is less than 5 ()% is maintained for 4 hours, and when the minimum operation time (for example, 4 hours) is exceeded, the mold proof operation is stopped. Figure 12 shows the experimental results of comparing the growth rate of mold, that is, the length of the mycelium during a certain period of time or when the holder is exposed to ambient gas: Fig. As shown in the results of Fig. 12, when the state of the relative humidity of 5 (% or less) is maintained for at least 4 hours, the operation is performed every 1 day, and in the case of high humidity, for example, water droplets often remain on the bathroom floor. Compared with the state, the growth rate of mold can be reduced by about 1 /5. Further, in the above description, an example has been described in which the sway angle of the louver 13 is switched from the wide angle (110 degrees) to the front (60 degrees) and the humidity is used as a reference. However, it is also possible to switch depending on the indoor temperature without depending on the humidity. Example 2148-9858-PF; Ahddub 12 1374243 ‘If the room temperature is high, it is assumed that the humidity is low and the same as the above humidity. • In addition, although the swing angle of the louver 13 is switched from the wide angle (110 degrees) to the front (60 degrees), the humidity can be set without switching to the preset operation time. Further, although the example in which the sway angle of the louver 13 is set to two stages has been described, the combination of the control of the wall surface and the ground may be performed by changing the air blowing range to a smaller scale. Further, although the reference for switching the swing angle of the louver 13 is described as an example of less than -50% (S21), the same effect can be obtained by setting an arbitrary value of 60% or less. Further, although the state in which the humidity is less than 50% has been described as an example in which the operation is continued for 4 hours or more (S24), the humidity may be set to any value less than 6〇%, and the operation time may be 3 hours or longer. Further, the shortest running time is when the dehumidifying capacity of the dehumidifier is about 1 〇 φ liter per day, and the above 4 hours and 6 hours are most suitable (S19, S20), but the present invention is not limited thereto, and it is preferable to borrow The optimum value is achieved by the dehumidification capacity of the dehumidifier or the amount of air blown out. Further, although the shortest operation time has been exemplified by two types (4 hours and 6 hours), it may be set to a minimum time of two or more arbitrary numbers corresponding to the indoor temperature, and may be appropriately switched in accordance with the indoor temperature. Further, when the refrigerant-type dehumidifier of the present embodiment is used, and the dehumidifier that functions as a cold air evaporator that passes through the wind and the condenser that is a warm air is blown by the wind, the air blowing range is switched. It is also possible to use 2l48-9858-PF; Ahddub 13 1374243 to switch the combination of the cold air outlet 10a and the warm air outlet 1b. In this case, in the latter half of the operation (in the case of the first drawing, the humidity is less than 50%), the warm air is blown to the ground to accelerate the evaporation of the water droplets. Further, the mechanism for changing the air blowing range to the ground direction is not limited to the change in the operating angle of the louver 13, and the lower blowing dedicated air passage may be provided in the main body of the dehumidifier 1 by switching the air passage. Further, the dehumidification method of the dehumidifier is not limited to the use of a vapor compression type such as a chlorofluorocarbon. It is also possible to use a non-drip method of an absorbent element such as a stone element or a Peiter element, and a dehumidification method. Not limited. Further, the present invention is also applicable to a machine having a function of % low relative humidity using a warm air blower having a heating device of an electric heater (such as a ceramic heater). Further, the mechanism for changing the blowing range of the air (process air) for dehumidifying treatment is not limited to the form of the louver i 3 shown in Fig. 7, and the relevant form can be appropriately changed. ) Figure 5 to illustrate. FIG. 14 to FIG. 16 are explanatory views showing an example in which the wind deflector 40 having the curved surface of the louver is slidably provided on the upper surface of the louver 13 and the wind guide fe4G is superposed on the louver 13 via the f. , constitutes a new style part of the dehumidifier 1. When the air deflector 4 is made. When sliding and pulling out further than the louver 13, the driving amount of the louver driving motor 34 is the same as that in the case of Fig. 9, as shown in Fig. 16, the wind is oriented closer to the ground. The wind deflector 40 is illustrated as a manual fixed type, and the user can select the position of the wind deflector 4Q before starting the operation, but can also make 14 2148-9858-PF; Ahddub 1374243 The aforementioned mechanism is an automatically implemented structure (not shown). In this way, when the air supply range is changed, by moving the air deflector 4 at the same time, the range of the air moving toward the ground: direction can be further increased, and drying can be performed in a shorter time. Further, the shape of the wind deflector 40 is not limited to the shape of the new pattern, and the shape of the larger air blowing range is preferentially considered. As described above, the dehumidification machine of the present embodiment has the above configuration and operates, so that the following effects can be obtained.

When the dehumidifier of the present embodiment is used, it has indoors: inlet (cold-air suction port 15, warm-air suction port 16) and treatment empty:: = (front air outlet 1); changing process air blowing Directional mechanism (Hundreds of chimneys 1 3), the air to be inhaled "... or heating to reduce the relative thirsty sound function (evaporator 20, condenser 22, etc.); detect the room temperature temperature detection mechanism 31; Humidity detection mechanism 32 for detecting humidity; and ~, degree to automatically start or stop operation control, to the temperature and humidity range according to indoor temperature and humidity change during operation. In the state of the air, the direction of the air must be dry, and the air can be dried in a short period of time. For example, the dry and dry molds that are dehumidified can be blown out to promote the thirst. #足进The evaporation of water droplets 'by this, can suppress the rise of the air humidity, and at the same time, by Harbin " " Therefore, it can obtain a dehumidifier with a high degree of mildew effect.

▲When the dehumidifier of the seven forms is used, the corresponding gamma sound is used to switch the air supply range L to the internal degree or the connection, and the HP is dry, and the field reaches the preset set thirst, and the value is made. The following thirsty sounds 'remaining spread' maintained - after a fixed time, automatically stop dehumidification 2148-9858-PF; Ahddub ^ 1^/4243 run 'so the 'low humidity air necessary to maintain a certain degree in the drying room: : Wide: The growth of mycelium is completed without excessive dehumidification. Moreover, the air blowing range (front line) is used to make the imaginary name a good name; the open surface of the 10 is better than the blowing range of the treatment of the second milk (for example, the institution that changes in the operation... 13), in addition to the outside, but also 铱, 〆 〆 秘 秘 秘 丨 丨 运 运 运 运 运 运 运 运 运 运 圊 圊 七 七 七 七 七 七 七 七 七 七 七 七 七 七

The mechanism that is operated by the S; Ρ! Mo m silk dry solid, etc., can change the indoor state by the H-side and go to the field in the direction of the field, and can dry the room in a short time. 'Processing air delivery. ^ _ 13) towards θ τ,,, π, there are mechanisms (such as blinds 3) facing the full range of winds such as hundreds of windows m Qin ^ H 8 w) 'and the aforementioned The mechanism (for example, when the air is approaching the ground direction (refer to the full range of air supply in the above-mentioned range), the air caused by the field is prevented from being caused by the indoor blade factory and the humidity and humidity ^ ^ Μ Έ ^ A "This way, this outline makes the air/dishness and humidity of the treatment air uniform, and the efficiency of the treatment of the old and the dangers is the same as the efficiency of the dry treatment, and at the same time, the wind is sent to the direction of the Lu, and the corpse is improved. Wind speed in the direction of the board or wall, but can be “n-changed or evaporated” near the ceiling or wall. When changing the air supply range, J: can be sturdy and concentrated towards the ceiling or wall. It is easy to store the wind in the direction of the water droplets, and it can fully perform the drying. When the product is in operation, the indoor air humidity is reduced, the water droplets are easily dripped, and the zinc ± , ^ fine is supplied by the wind toward the ceiling or the wall. Efficiency Dehumidification and depletion ★ There is y :....... The relative humidity in the second gas is lower than the set humidity or more than the preset time, so there is no need to stir the air greatly, 2148-9858-PF/Ahddub 16 /4243 Therefore, changing the air supply range toward the naturalized plate or wall It is easy to accumulate the ground direction of the water droplets, and it is possible to dry the ground sufficiently to reduce the drying time. 2. And the mechanism for changing the air supply range more greatly has the shape of the air outlet formed by blowing the 0 and the louver 13 on the front side to manually Or automatically change the structure (refer to the same, .. X eye diagram), there is also the position of the fixed shaft position, the upper end of the air supply range, the upper end side of the target circumference, and either or both of the side and the lower side Made by hand or automatically by matching the direction of the square to be dried & +

Wish, change the shape of the blowout, and get the range of air supply for the corresponding use. By changing the "mechanism of the blowing direction of the air outlet", the plate-shaped member (see Fig. 13 and the like) is movable in consideration of a new style, whereby the new type of component can be used without any sudden change before the operation. The air supply range is expanded, because the parts are moved in consideration of the new type of surface, so that the blowing range can be changed in a new way. The mechanism for changing the shape of the above-mentioned air outlet is made to expand toward the ground. The shape of the air supply range can also be used to send air to the previous general dehumidifier, which is difficult to supply air. The earth is moved to the north of the main body, and the phoenix is close to the ground on the front side of the main body. , 县 避 ; ; 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登 登Therefore, the user can perform the operation appropriately in accordance with the indoor environment without manual tidying. Further, the setting value when the air supply range is switched is set to a relative humidity of less than 60%. After the inner air or the ceiling and the wall surface are dried, the processing air having a relative humidity of less than 60% is concentrated and supplied to the ground direction, thereby suppressing the accumulation of water in the water 2148-9858-PF/Ahddub 17 and the mold is easily generated. The mold grows on the ground. And 'When the relative humidity below the preset value is less than 60%, it is maintained for more than 3 hours'. After the set time is maintained, it stops automatically. Therefore, it is not necessary to continuously maintain the low humidity ambient air. By maintaining only a minimum dehumidification turn time, a dehumidifier that saves energy and inhibits mold growth is obtained. - Again, during dehumidification operation where dew condensation or water droplets are easily generated, by providing a minimum operation Time, the user does not need to adjust the running time, can get the drying effect in any environment. People, take low running time ~ 'Tu / U Han Han < 攸 调 调 ' ' 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应The user does not need to adjust the running time, and can perform a certain operation suitable for the indoor temperature in any environment, and can obtain a more stable drying effect. The time is such that when the indoor temperature is low, the operation time is longer in the case where the ratio is higher than the internal temperature, so that even when the internal temperature is low, sufficient drying effect can be obtained. The minimum running time, choose Zhuo and a 4 , ^ ^ Y field is more than 20t when the indoor temperature is hour, although it does not exceed 2室内 of the indoor temperature. ® θ Α, the horse is 6 hours, so as long as the general residence The room or the room, ^ ^ .
