Description

  The present invention relates to a dehumidifying device having a rotary adsorbent (dehumidifying rotor).

  In recent years, in a dehumidifier equipped with a rotary adsorbent (dehumidification rotor) used mainly in general households, the air used for regeneration of the adsorbent is circulated to a high dew point state, and the air in the high dew point state is moved indoors. It is common to perform dehumidification by cooling with air and condensing and collecting it as condensed water (see, for example, Patent Document 1).

  Hereinafter, a conventional dehumidifier will be described with reference to FIG.

  FIG. 12 is a simplified cross-sectional view showing the configuration of a conventional dehumidifier that circulates air used for regeneration and collects it as dew condensation water. As shown in FIG. In the main body 101, moisture is absorbed from the first air 102 in the moisture absorption region 105, and in the regeneration region 106, the moisture is released to the second air 108 heated by the heating means 107. An adsorbent 109 to be regenerated, a driving means 110 for rotating the adsorbent 109 so that moisture absorption from the first air 102 in the moisture absorption region 105 and moisture release to the second air 108 in the regeneration region 106 are repeatedly performed; The second air 108 that has flowed out of the region 106 is cooled by the first air 102, and the moisture from the adsorbent 109 is collected as condensed water, and the suction port 103 is connected to the second air 108. A first air supply means 112 that sucks air 102 and supplies it to the moisture absorption area 105 and the condenser 111; a second air supply means 113 that circulates the second air 108 in the order of the heating means 107, the regeneration area 106, and the condenser 111; It has.

  The operation of the dehumidifier configured as described above will be described. The first air 102 is sucked from the suction port 103 by the first air supply means 112 and supplied to the condenser 111 to cool and dehumidify the second air 108. Thereafter, the moisture is supplied to the moisture absorption region 105. In the moisture absorption region 105, the first air 102 is absorbed by the adsorbent 109 to become dry air, and is blown out of the apparatus from the blowout port 104. On the other hand, the second air 108 circulated by the second air supply means 113 is heated by the heating means 107 and is supplied to the regeneration region 106 at a high temperature. The second air 108, which contains the moisture dehumidified from the adsorbent 109 by heating and regenerating the adsorbent 109 in the regeneration region 106, is supplied to the condenser 111, and is cooled below the dew point temperature by the first air 102. Is done. The second air 108 cooled and dehumidified in the condenser 111 is sucked into the second air supply means 113 and the above operation is repeated. By this circulation, the second air 108 maintains a dew point higher than the temperature of the first air 102, and condensation in the condenser 111 is promoted. Moisture in the second air 108 condensed by the condenser 111 is drained to the outside from the condenser drain port 114. The amount of the dewed condensed water corresponds to the dehumidifying amount of the dehumidifying device. Further, since there is a limit to the amount of moisture absorbed by the adsorbent 109, the adsorbent 109 is rotated and moved by the driving means 110 so that the adsorbent 109 is not saturated, and the hygroscopic area 105 absorbs moisture from the first air 102 and the regeneration area 106. The second air 108 is repeatedly dehumidified to enable continuous dehumidification operation for a long time.

  Further, in order to prevent overheating of the regeneration chamber 115 connecting the regeneration region 106 of the adsorbent 109 and the condenser 111, the temperature of the second air 108 flowing into the regeneration chamber 115 from the regeneration region 106 is detected and the temperature rises. In some cases, the safety device operates to stop the dehumidifying operation (for example, see Patent Document 2).

FIG. 13 is a structural perspective view showing an attachment state of the temperature sensor 116 for preventing the regeneration chamber 115 from being heated in the conventional dehumidifying apparatus. As shown in FIG. 13, a regeneration chamber 115 that connects the regeneration region 106 of the adsorbent and the condenser 111 is provided on a partition plate 117 that rotatably supports the adsorbent 109 by the driving means 110. A temperature sensor 116 is attached to the regeneration chamber 115 in order to detect the temperature of the second air 108 that has flowed out of the regeneration region 106. The second air 108 that has passed through the regeneration region 106 of the adsorbent 109 is guided to the condenser 111 by the regeneration chamber 115. If the temperature of the second air 108 becomes abnormally high, the temperature sensor 116 attached to the regeneration chamber 115 detects the high temperature second air 108 and stops the dehumidifying operation. As a result, the regeneration chamber 115 and other main parts are prevented from being deformed by heat.

  In the conventional dehumidifier described above, the temperature sensor 116 detects the temperature at which the second air 108 that has passed through the regeneration chamber 115 is mixed to some extent. Normally, the regeneration region 106 of the adsorbent 109 has a temperature distribution with respect to the rotation direction of the adsorbent 109, and the temperature increases as the adsorbent 109 advances through the regeneration region 106. In the above case, when the operation of the driving means 110 of the adsorbent 109 is stopped, the temperature rises locally in the rear stage of the rotation direction of the adsorbent 109 in the regeneration region 106, although the temperature suddenly increases. There is a situation in which the detection value of the sensor 116 is within the normal value range, a time lag occurs in the detection value, and there is a possibility that deterioration such as deformation occurs in the regeneration chamber 115 and surrounding resin parts before an abnormality is detected. It was.

  Further, when an abnormality occurs in the first air supply unit 112 and the supply amount of the first air 102 is remarkably reduced, or when the first air 102 is low in humidity, the moisture adsorption in the moisture absorption region 105 of the adsorbent 109 is small. It moves to the reproduction area 106 as it is. Since the regeneration region 106 is heated more than necessary, the temperature of the second air 108 in the regeneration chamber 115 rises. In this case, the temperature distribution in the regeneration region 106 of the adsorbent 109 as described above becomes more prominent and the time lag of the detection value becomes further larger. Therefore, before the abnormality is detected, the regeneration chamber 115 and surrounding resin parts are deformed. There was a possibility that deterioration such as the above would occur.

  The present invention is intended to solve the problems of such a conventional configuration. The abnormal state is quickly detected, and even if the abnormal state occurs, the reproduction chamber 115 and the main parts are deteriorated.

According to the present invention, the temperature detecting means 31 is provided in the adsorbent partition 27, so that the adsorbent in the adsorbent partition 27 having the highest possibility of deterioration such as deformation due to heat dissipation of the adsorbent 109 is obtained. Since the temperature of the adsorbent 109 can be surely adjusted by the temperature adjusting means 37, it is possible to prevent deterioration of the adsorbent partitioning portion 27 such as deformation due to heat radiation from the adsorbent 109. A highly reliable dehumidifying device can be provided. The temperature of the surface of the adsorbent 109 can be directly detected, and an abnormality can be detected without being influenced by the temperature distribution in the regeneration area 106, and the temperature rise of the regeneration area 106 and the time lag between abnormality detection are reduced. Temperature can be adjusted, and heat dissipation from the adsorbent 109 can be adjusted.

Even with this, it is possible to provide a highly reliable dehumidifying device that can be operated without any problem.

Further, according to the second problem solving means, the outer surface of the temperature detecting means 31 is disposed so as to be substantially flush with the adsorbent facing surface 28 of the adsorbent partitioning portion 27, whereby the adsorbent 109 is arranged. In addition to being able to detect the temperature of the adsorbent 109 in the adsorbent partitioning portion 27 with the highest possibility of deterioration such as deformation due to heat dissipation, the temperature detecting means 31 can be disposed closest to the adsorbent 109. Therefore, it is possible to reduce the time lag between the occurrence of an abnormal state and the detection of the abnormal state and to suppress the heat radiation from the adsorbent 109, thereby eliminating deterioration such as deformation of the adsorbent partition 27 and main parts, It is possible to provide a highly reliable dehumidifying device that can be operated without any trouble even after returning.

  Further, if the temperature detecting means 31 is arranged so as to be flush with the adsorbent facing surface 28, the function of partitioning the adsorbent facing surface 28 so as not to mix the first air 102 and the second air 108 is obstructed. Therefore, it is possible to prevent leakage due to wind leakage of the second air 108 to the first air 102 air passage.

It is possible to detect the temperature of the adsorbent 109 in the adsorbent partitioning portion 27 that has the highest possibility of deterioration such as deformation due to heat dissipation of the adsorbent 109. Therefore, since the time lag between the occurrence of an abnormal state and the detection of the abnormal state can be reduced and the measure to suppress the heat radiation from the adsorbent 109 can be performed, the deterioration of the adsorbent partition 27 and deformation of the main parts is eliminated, It is possible to provide a highly reliable dehumidifying device that can be operated without any trouble even after returning.

By detecting the temperature of the adsorbent 109 through the air, it is possible to reduce the influence of ambient air and the temperature of the parts, and the accurate temperature of the adsorbent 109 can be detected, so an abnormal state has occurred. Since the abnormality can be detected quickly and accurately, the time lag between the occurrence of the abnormal state and the detection of the abnormal state can be reduced, and the measure for suppressing the heat radiation from the adsorbent 109 can be performed. It is possible to provide a highly reliable dehumidifying device that eliminates the deterioration of the deformation of the portion 27 and the main parts and can be operated without any trouble even if it is restored.

Therefore, the heat radiation from the adsorbent 109 can be adjusted, and even if an abnormal state occurs, the adsorbent partition 27 and main parts are not deformed and deteriorated. An apparatus can be provided.

Further, according to the ninth problem solving means, the rotation speed control means 41 increases the rotation speed of the adsorbent 109 when the detection value of the temperature detection means 31 becomes equal to or higher than a set value.

This makes it possible to adjust the temperature of the adsorbent 109, so that the heat radiation from the adsorbent 109 can be adjusted, and even if an abnormal state occurs, the deterioration of the adsorbent partition 27 and main parts is not deteriorated and the return is restored. Even with this, it is possible to provide a highly reliable dehumidifying device that can be operated without any problem.

Further, according to the thirteenth problem solving means, the first air supply amount control means 43 supplies the first air 102 of the first air supply means 112 when the detection value of the temperature detection means 31 becomes a set value or more. By increasing the amount, the amount of moisture adsorbed by the adsorbent 109 in the moisture absorption area 105 is increased, and when the adsorbent 109 moves to the regeneration area 106, the adsorbent 109 becomes nearly dry at a later stage in the adsorbent rotation direction. Since the amount of heat released from the adsorbent 109 is reduced and the adsorbent partition 27 is prevented from being overheated, even if an abnormal state occurs, the adsorbent partition 27 and the main parts are not deformed. It is possible to provide a highly reliable dehumidifying device that can eliminate the deterioration and can be operated without any trouble even when the operation is restored.

(Embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is used about the component same as the conventional example, and detailed description is abbreviate | omitted.

  First, a schematic configuration of the dehumidifying device in the present invention will be described.

  FIG. 1 is a simple exploded view showing a schematic configuration of a dehumidifying apparatus according to an embodiment of the present invention.

  As shown in FIG. 1, this dehumidifier opens a suction port 103 and a blower outlet 104 in a case 1 that forms the outline of a main body 101, and sucks the first air 102 in the room from the suction port 103 into the main body 101. First air supply means 112 that blows into the room from the outlet 104 is provided.

  The regeneration unit 2 having the function of heating and regenerating the adsorbent 109 is composed of a regeneration chamber 115 and a heating means 107.

  The regeneration chamber 115 is provided with a rotating shaft 3 that rotatably supports the adsorbent 109. The adsorbent 109 is fitted into the rotation shaft 3 of the regeneration chamber 115 so that the heating means 107 and the regeneration chamber 115 are rotated. A plurality of points on the outer periphery in the circumferential direction of the shaft 3 and the regeneration chamber 115 are pivoted to each other. In the adsorbent 109, the portion covered by the regeneration unit 2 is a regeneration region 106, and the other part is separated from the moisture absorption region 105. The reproduction unit 2 is fixed by screwing a circumferential outline portion to the partition plate 117.

  The first air supply means 112 supplies the indoor first air 102 to the moisture absorption area 105 to absorb moisture to the adsorbent 109, and the regeneration area 106 is heated by the second air supply means 113 connected to the heating means 107. The adsorbent 109 is dehumidified and regenerated by supplying high-temperature second air 108 through the means 107.

  The second air supply means 113 is connected in proximity to the heating means 107 and is arranged on the downstream side of the adsorbent 109 in the ventilation direction of the first air 102 as in the heating means 107.

  A hollow condenser 111 having an inlet pipe 4, an outlet pipe 5, and a condenser drain port 114 is provided upstream of the first air 102 in the adsorbent 109 in the ventilation direction, and the first air 102 supplied to the regeneration region 106 is provided. Is introduced into the condenser 111 from the inlet pipe 4 and connected to return to the second air supply means 113 from the outlet pipe 5 through the connection duct 6 provided in the partition plate 117 to form the circulation air passage 7. Yes. The condenser 111 has a plurality of ventilation holes 8 through which air can be ventilated, and the first air 102 blown by the first air supply means 112 is passed through the ventilation holes 8 to circulate in the condenser 111. 2 The air 108 is cooled below its dew point temperature to cause condensation. Moisture in the second air 108 condensed on the inner surface of the condenser 111 is dropped downward by its own weight, collected in the water receiving tank 9 from the condenser drain port 114, and guided to the water storage tank 10. By removing the water storage tank 10 from the main body 101 and draining it, the condensed water is treated.

  FIG. 2 is a configuration explanatory view showing the configuration of the suction rotor assembly 11 that enables protection and rotation operation of the suction material 109.

  As shown in FIG. 2, the adsorbent 109 is made by laminating and laminating flat paper made by mixing inorganic fibers such as ceramic fibers and glass fibers, or these inorganic fibers and pulp, and corrugated paper. It is formed in a disk shape and is composed of one or more types of adsorbent materials such as zeolite, silica gel, activated carbon, etc., and has a structure that has a large number of small holes in the direction of the arrows and allows ventilation. It has become. When the adsorbent 109 contains a relatively large amount of moisture, when air with relatively low humidity, for example, heated air passes, moisture is released into the passing air, and the adsorbent 109 is relatively dry. In addition, when air having a relatively high humidity, for example, indoor air, passes through, moisture in the passing air is absorbed.

  The adsorbent 109 is held by a rotor frame A13 and a rotor frame B14 that are the frame bodies 12 holding the adsorbent 109. The adsorbent 109 is housed in the rotor frame A13, and is prevented from dropping by a stopper 15 provided on one end surface of the rotor frame A13. A rotor frame B14 is fitted along the outer periphery to the opposite end side of the rotor frame A13, and is fixed to the rotor frame A13 by screwing a plurality of locations. A boss receiving portion 16 is provided at the center of the rotor frame B14, and the ribs 17 are bridged radially from the boss receiving portion 16 so that the rotor boss 18 fitted into the central shaft hole of the adsorbent 109 from the opposite side of the rotor frame B14 is the boss receiving portion. By fixing with screwing at 16, the relative position of the rotor frame A13 and the rotor boss 18 is defined, and the adsorbent 109 is protected and held. Each rib 17 is bridged by a ring portion 19 and maintains strength. One or more ring portions 19 may be provided. If the diameter of the adsorbent is large, a plurality of ring portions 19 are preferably provided. Further, a rotor gear 20 for enabling rotation of the suction rotor assembly 11 is formed on the outer periphery of the rotor frame A13 by integral molding with the rotor frame A13 and the stopper 15. Since the rotor frame B14 is rust-proof and requires high strength with a thin plate thickness, it is manufactured by pressing and bending a stainless steel plate having a plate thickness of 0.4 to 1.0 mm, preferably 0.4 mm. Used.

  FIG. 3 is a configuration explanatory view showing the configuration of the regeneration unit 2 including the heating means 107 and the regeneration chamber 115 for performing heating regeneration of the adsorbent 109.

  As shown in FIG. 3, the heating means 107 is configured by inserting a heater 22 into a fan-shaped heater case 21 and covering with a heater lid 23. The heater case 21 is provided with an inflow portion 24 for the second air 108, and the second air supply means 113 is connected to the inflow portion 24. The heater lid 23 has an outflow portion 25 for the second air 108 opened. The regeneration chamber 115 is formed in a fan-shaped box shape, and includes a condenser connection port 26 for connecting the condenser 111 and an adsorbent partitioning portion 27. As shown in FIG. 1, the condenser 111 has the inlet pipe 4 and the outlet pipe 5 arranged below the condenser 111, and the air path of the second air 108 is turned at the upper part of the condenser 111, so that heat exchange is performed. In order to increase the area, it is advantageous to dispose the inlet pipe 4 and the outlet pipe 5 as downward as possible. Therefore, the condenser connection port 26 is disposed as downward as possible in the regeneration chamber 115. Further, the adsorbent partitioning section 27 divides the moisture absorption area 105 and the regeneration area 106 of the adsorbent 109 and has an adsorbent facing surface 28. The adsorbent facing surface 28 is disposed so as to face the adsorbent 109, and is further disposed so as to face the heater seal portion 29 provided on the heater lid 23 of the heating means 107. Mixing of the first air 102 passing through and the second air 108 passing through the regeneration region 106 is suppressed. The end of the adsorbent facing surface 28 is chamfered so that the rotor frame B14 is not caught when the adsorption rotor assembly 11 is rotated. If the gap between the adsorbent facing surface 28 and the end face of the adsorbent 109 and the gap between the heater seal portion 29 and the end face of the adsorbent 109 are reduced, the sealing performance can be ensured. There is a possibility that the heater seal portion 29 and the adsorbent 109 may be touched and damaged due to manufacturing errors. For this reason, the clearance between the adsorbent facing surface 28 and the end face of the adsorbent 109 is preferably 0.6 mm to 1.0 mm, preferably 0.7 mm or less, taking into account that the rotor frame B14 is interposed. Further, the gap between the heater seal portion 29 and the end face of the adsorbent 109 is preferably 0.2 mm to 0.5 mm, preferably 0.3 mm or less.

  A columnar rotation shaft 3 for rotatably supporting the suction rotor assembly 11 is provided at the fan-shaped central portion of the reproduction chamber 115. The adsorption rotor assembly 11 is pivotally mounted on the rotation shaft 3 of the regeneration chamber 115, and the adsorption rotor assembly 11 is supported so as to be sandwiched between the regeneration chamber 115 and the heating means 107. The regeneration chamber 115 and the heating means 107 are fixed by screwing the central portion of the rotating shaft 3 and the outer shell in the circumferential direction at a plurality of points. Thereby, since the adsorbent partition part 27 and the rotating shaft 3 can be integrally molded as a relatively small same part, it can be molded with high dimensional accuracy. Further, since the adsorbent 109, the regeneration chamber 115, and the heating means 107 can be manufactured as a unit, even if the installation of the regeneration section 2 on the partition plate 117 is distorted, the adsorbent partition section 27, the heater seal section 29, and the adsorbent The positional relationship of 109 does not go out of order, and the gap between the adsorbent partition 27 and the end face of the adsorbent 109 can be manufactured with high accuracy. As a result, mixing of the first air 102 passing through the moisture absorption region 105 of the adsorbent 109 and the second air 108 passing through the regeneration region 106 can be suppressed, and the sealing performance can be ensured. In addition, since the regeneration chamber 115 may be at a high temperature, when it is molded as a resin molded product, it is desirable to mold it with a heat resistant material such as PET resin or PPS resin. In addition, since the regeneration unit 2 is formed as a separate part from the partition plate 117, only the regeneration chamber 115 needs to be made of a heat resistant material, and other parts need not be made of expensive materials, which is economical. The second air 108 supplied from the second air supply means 113 flows into the heater case 21, is heated by the heater 22, flows into the regeneration region 106 of the adsorbent 109, and dehumidifies moisture from the adsorbent 109. Then, it is guided to the condenser 111 by the regeneration chamber 115.

  Further, the adsorbent partition 27 of the regeneration chamber 115 detects the temperature of the second air outflow surface of the adsorbent 109 that constitutes the partition protection means 30 that protects the adsorbent partition 27 from the heat dissipation of the adsorbent 109. Temperature detecting means 31 is provided. The temperature detecting means 31 is provided in the adsorbent partitioning portion 27 on the rear stage side in the rotation direction of the adsorbent 109 of the regeneration chamber 115.

  FIG. 4A is a schematic view showing the regeneration region 106 and the moisture absorption region 105 when the adsorbent 109 is viewed from the outlet side of the second air 108, and FIG. 4B is a diagram in FIG. It is explanatory drawing which showed the temperature distribution of the adsorbent 109 end surface along the solid line arrow.

  Immediately after entering the reproduction region 106 (in the vicinity of A), the temperature rises because the temperature is raised by the heating means 107. As the rotation proceeds, the moisture release of the adsorbent 109 is stabilized, the temperature rises gently (X portion in the figure), and the moisture adsorbed by the adsorbent 109 in the rear stage (near B) of the regeneration region 106. Most of the heat is released, and the amount of heat input by the heating means 107 is released as it is, and the temperature rises rapidly. And if it enters into the moisture absorption area | region 105, it will be cooled by the 1st air 102 and temperature will be lowered | hung. The above temperature change is repeated, and the adsorbent 109 repeats moisture absorption and regeneration while rotating. As described above, the portion of the adsorbent 109 at the outlet end surface of the second air 108 that has the maximum temperature is the point B in the drawing, that is, the adsorbent partitioning portion 27 at the rear stage of the adsorbent 109 in the rotation direction of the regeneration chamber 115. . On the other hand, if the temperature is detected in the vicinity of the condenser connection port 26 as in the conventional example, only the temperature obtained by averaging the entire regeneration region 106 can be detected. Depending on the temperature / humidity conditions of the atmosphere and the usage conditions of the dehumidifier, the temperature distribution may become even sharper. In such a case, a large difference occurs between the averaged temperature and the maximum temperature, and there is a possibility that the adsorbent partition 27 may be deteriorated before the protection control is activated. In addition, when a situation such as a sudden decrease in the supply amount of the first air 102 or a sudden decrease in the relative humidity of the first air 102 occurs, the temperature rises first at point B. In that case, before the temperature detecting means 31 detects an abnormality, the heat deformation temperature of the adsorbent partitioning portion 27 may be exceeded at point B and deterioration such as melting and deformation may occur. Therefore, the temperature detecting means 31 is arranged at the above point B as shown in FIG. Thereby, by detecting the temperature of the adsorbent 109 at the position of the maximum temperature, the temperature can be directly measured at the most dangerous part, and the temperature can be detected without a time lag.

  5, 6 (a), and 6 (b) are explanatory diagrams showing details of the temperature detection means 31. FIG. 5 is an explanatory view showing details of the state of attachment of the temperature detecting means 31 to the adsorbent partitioning portion 27, and FIG. 6A shows the positional relationship between the adsorbent 109 and the temperature detecting means 31 in FIG. FIG. 6B is a cross-sectional explanatory view shown in the −V cross section, and FIG. 6B is a cross-sectional explanatory view showing the positional relationship between the adsorbent 109 and the temperature detecting means 31 in the other embodiment in the VV cross section in FIG. FIG.

  First, FIG. 6A will be described. The temperature detection means 31 has a detection part 32 and a flange part 33 for detecting the temperature. An opening 34 into which the temperature detecting means 31 is fitted is provided in the adsorbent partitioning portion 27 of the regeneration chamber 115, and a cylindrical guide portion 35 is provided so as to surround the detecting portion 32. The detection unit 32 is directed toward the adsorbent 109 and is fixed by screwing the flange portion 33 to the adsorbent partitioning portion 27 of the regeneration chamber 115 so that the detection unit 32 can be installed close to the adsorbent 109. . In order to accurately measure the temperature of the surface of the adsorbent 109, it is advantageous that the detection unit 32 is as close as possible to the surface of the adsorbent 109. On the other hand, if it is too close, manufacturing errors and attachment of the temperature detection means 31 and the adsorbent 109 There is a possibility of contact and damage due to errors. Therefore, the gap (D in FIG. 6A) between the detection unit 32 and the adsorbent 109 end surface is preferably 0.6 mm to 1.0 mm, and preferably 0.7 mm or less. Further, as described with reference to FIG. 3, the adsorbent facing surface 28 of the adsorbent partitioning portion 27 is disposed in the vicinity of the adsorbent 109, so that the adsorbent facing surface 28 and the detection unit 32 are flush with each other. By installing the detector in the vicinity of the adsorbent 109, the detector 32 can be easily arranged. Further, since the function of preventing the first air 102 and the second air 108 from mixing in the adsorbent partitioning portion 27 is not impaired, the dehumidification efficiency is not lowered due to air leakage. By attaching the temperature detection means 31 as described above, an air layer 36 is formed between the end faces of the temperature detection means 31 adsorbent 109 as shown in FIG. Thereby, the influence which it receives from ambient air and component temperature can be decreased, and the temperature of the end surface of the adsorbent 109 can be detected accurately.

  The embodiment of FIG. 6B will be described. The temperature detecting means 31 is arranged in the adsorbent partitioning portion 27 so that the detecting portion 32 is located at a position facing the ring portion 19 of the rotor frame B14 which is the frame body 12. Thereby, the temperature detection means 31 detects the end surface temperature of the adsorbent 109 through the ring portion 19 of the rotor frame B14 which is the frame body 12. As shown in FIG. 2, since the rotor frame B14 is made of a stainless steel plate or the like in order to reduce the thickness while ensuring strength, the thermal conductivity is good and the temperature of the adsorbent surface can be transmitted well. On the other hand, the gap (E in FIG. 6B) between the ring part 19 and the detection part 32 can be arranged closer to 0.2 to 0.5 mm. Therefore, it is possible to reduce the influence of ambient air and component temperature, and to detect the temperature of the adsorbent 109 accurately.

In addition, although it is set as the temperature detection means 31 which provided the flange part 33, and it is set as the structure which screws, it should just be comprised so that the detection part 32 may be provided in proximity to the adsorbent 109, for example, a flat plate-shaped temperature detection means is used. There is no difference in operation and effect even with a fixing method or the like embedded in the adsorbent partitioning portion 27, and the configuration of the fixing method and temperature detection means is not limited. FIGS. 7A and 7B show the partition protection means 30. It is a block circuit diagram for explaining the configuration of a heating amount control means 38 which is one of the temperature adjustment means 37 for adjusting the temperature of the adsorbing material 109 and the explanatory diagram of the control sequence.

  As shown in FIG. 7A, the control unit 39 in the dehumidifying device is provided with a control device 40 (for example, a microcomputer) and a heating amount control means 38 for controlling the output of the heating means 107.

  In the above configuration, main operations will be described with reference to FIG.

  For some reason (the rotation of the adsorbent 109 stops, the supply amount of the first air 102 decreases, the relative humidity of the first air 102 decreases, etc.), the detected value of the temperature detecting means 31 increases, and the detected value becomes When the set value (= protection set value) is exceeded, the heating amount control means 38 reduces or stops the output of the heating means 107. As a result, the amount of heat input to the adsorbent 109 decreases, so that the temperature of the second air 108 outflow end surface of the adsorbent 109 decreases and the detection value of the temperature detecting means 31 also decreases. Therefore, overheating of the adsorbent 109 by the heating means 107 is eliminated, and overheating of the adsorbent partition portion 27 of the regeneration chamber 115 due to heat dissipation of the adsorbent 109 is prevented. In addition, it is possible to eliminate the deterioration of the main parts and the deformation of the main parts, and to operate without any trouble even if it returns. Further, when the detected value falls below the set value (= return set value), the heating amount control means 38 can return the output of the heating means 107 to the original state. In such a configuration, when the abnormal state is resolved, the dehumidifying operation automatically returns to the normal operating state, so that the user does not have to reset the operation of the dehumidifying device.

  Further, the protection set value needs to be equal to or lower than the heat deformation temperature of the material used for the regeneration chamber 115. Moreover, as shown in FIG. Even after the output is lowered, the temperature of the detection unit overshoots, so it is necessary to set it with a margin. Further, the return set value needs to be set lower than the protection set value in order to suppress the hunting of the heating means 107 between ON and OFF. For example, when the regeneration chamber 115 is manufactured using PPS resin, it is preferable that the protection set value is 120 ° C. and the return set value is 100 ° C. Hereinafter, the rotation speed control means 41 for adjusting the rotation speed of the adsorbent 109 as the temperature adjustment means 37 for the adsorbent 109, the second air supply amount control means 42 for adjusting the supply amount of the second air 108, and the first air 102. Although the first air supply amount control means 43 for adjusting the supply amount will be described, it is preferable to use the above set values for the protection set value and the return set value.

  In the present embodiment, the detection value of the temperature detection means 31 is determined by the control device 40 and controlled by the heating amount control means 38. However, the temperature detection means 31 may be a thermostat. As a result, the heating amount of the heating means 107 can be adjusted by turning on and off a part of the input of the heating means 107 by opening the protection setting value by the switch inside the thermostat and closing the return setting value. The temperature of the adsorbent partition 27 of the regeneration chamber 115 can be protected by adjusting the output of the means 107.

  FIGS. 8A and 8B show the partition protection means 30 and a rotational speed control means for adjusting the rotational speed of the adsorbent 109 that is one of the temperature adjusting means 37 for adjusting the temperature of the adsorbent 109. FIG. 4 is a block circuit diagram illustrating the configuration of 41 and an explanatory diagram of a control sequence.

  As shown in FIG. 8A, the control unit 39 in the dehumidifying device is provided with a control device 40 (for example, a microcomputer) and a rotation speed control means 41 for controlling the rotation speed of the adsorbent 109.

  In the above configuration, main operations will be described with reference to FIG.

  The detection value of the temperature detecting means 31 increases for some reason (the supply amount of the first air 102 decreases, the relative humidity of the first air 102 decreases, etc.), and the detection value becomes a set value (= protection set value). When the value exceeds, the rotational speed control means 41 increases the rotational speed of the driving means 110. As shown in FIG. 4B, in the subsequent stage (near B) of the regeneration region 106, most of the moisture adsorbed by the adsorbent 109 is released and is input by the heating means 107. The amount of heat will be released as it is, and the temperature will rise rapidly. By increasing the rotation speed of the adsorbent 109, the adsorbent 109 can be moved to the treatment area 105 before most of the moisture adsorbed by the adsorbent 109 is released, and the regeneration area 106 of the adsorbent 109 is recovered. Since the amount of heat released from the adsorbent 109 can be reduced at a later stage in the rotation direction of the adsorbent 109, the temperature at the outflow end surface of the second air 108 of the adsorbent 109 decreases, and the detected value of the temperature detecting means 31 also increases. It will decline. Thereby, even if an abnormal state occurs, it is possible to eliminate the deterioration of the adsorbent partitioning portion 27 and the main parts of the regeneration chamber 115 and the like and to operate without any trouble even if the recovery is performed. Further, when the detected value falls below the set value (= return set value), the rotation speed control means 41 can return the rotation speed of the drive means 110 to the original state. Thus, when the abnormal state is resolved, the dehumidifying operation automatically returns to the normal operating state, so that the user does not have to reset the operation of the dehumidifying device.

  FIGS. 9A and 9B show the partition air protecting means 30 and the second air for adjusting the supply amount of the second air 108 which is one of the temperature adjusting means 37 for adjusting the temperature of the adsorbent 109. It is a block circuit diagram explaining the configuration of the supply amount control means and an explanatory diagram of a control sequence.

  As shown in FIG. 9A, the control unit 39 in the dehumidifying device controls the control device 40 (for example, a microcomputer) and the second air supply means 113 to adjust the supply amount of the second air 108. Supply control means 42 is provided.

  In the above configuration, main operations will be described with reference to FIG.

  For some reason (the rotation of the adsorbent 109 stops, the supply amount of the first air 102 decreases, the relative humidity of the first air 102 decreases, etc.), the detected value of the temperature detecting means 31 increases, and the detected value becomes When the set value (= protection set value) is exceeded, the second air supply amount control means 42 decreases the supply amount of the second air 108. By reducing the supply amount of the second air 108, moisture release from the adsorbent 109 is intentionally suppressed, and regeneration of the adsorbent 109 is suppressed. This makes it difficult to create a state in which most of the moisture adsorbed by the adsorbent 109 has been released, and the temperature at the position B in FIG. Since the amount of heat released from the adsorbent 109 can be reduced at a later stage in the rotation direction of the adsorbent 109 in 106, the temperature of the outflow end surface of the second air 108 of the adsorbent 109 decreases, and the detected value of the temperature detecting means 31. Will also decline. Thereby, even if an abnormal state occurs, it is possible to eliminate the deterioration of the adsorbent partitioning portion 27 and the main parts of the regeneration chamber 115 and the like and to operate without any trouble even if the recovery is performed. When the detected value falls below the set value (= return set value), the second air supply amount control means 42 can return the supply amount of the second air 108 to the original state. Thus, when the abnormal state is resolved, the dehumidifying operation automatically returns to the normal operating state, so that the user does not have to reset the operation of the dehumidifying device.

  10A and 10B show the partition air protecting means 30 and the first air for adjusting the supply amount of the first air 102 which is one of the temperature adjusting means 37 for adjusting the temperature of the adsorbent 109. It is a block circuit diagram for explaining the configuration of the supply amount control means 43 and an explanatory diagram of a control sequence.

  As shown in FIG. 10A, the control unit 39 in the dehumidifying device controls the control device 40 (for example, a microcomputer) and the first air supply means 112 to adjust the supply amount of the first air 102. Supply amount control means 43 is provided.

  In the above configuration, main operations will be described with reference to FIG.

  The detection value of the temperature detection means 31 increases for some reason (such as the rotation of the adsorbent 109 stops, the relative humidity of the first air 102 decreases), and the detection value exceeds the set value (= protection set value). The first air supply amount control means 43 increases the supply amount of the first air 102. By increasing the supply amount of the first air 102, the moisture adsorption of the adsorbent 109 in the moisture absorption region 105 is increased. As a result, when the adsorbent 109 moves to the regeneration region 106, it is difficult to create a state in which most of the water adsorbed in B of FIG. 4B is released, and the temperature rise in this portion is suppressed. Since the amount of heat released from the adsorbent 109 can be reduced at a later stage in the rotation direction of the adsorbent 109 in the regeneration region 106 of the adsorbent 109, the temperature of the outflow end surface of the second air 108 of the adsorbent 109 can be reduced. Decreases, and the detection value of the temperature detecting means 31 also decreases. Thereby, even if an abnormal state occurs, it is possible to eliminate the deterioration of the adsorbent partitioning portion 27 and the main parts of the regeneration chamber 115 and the like and to operate without any trouble even if the recovery is performed. When the detected value falls below the set value (= return set value), the first air supply amount control means 43 can return the supply amount of the first air 102 to the original state. Thus, when the abnormal state is resolved, the dehumidifying operation automatically returns to the normal operating state, so that the user does not have to reset the operation of the dehumidifying device.

  FIG. 11 shows a heating amount control means 38, a rotation speed control means 41, a second air supply amount control means 42, and a first air supply amount control means 43 as temperature adjusting means 37 constituting the partition protection means 30. FIG. 2 is a block circuit diagram illustrating a configuration of an embodiment provided with

  As shown in FIG. 11, the control unit 39 in the dehumidifying device is provided with a control device 40 (for example, a microcomputer). The controller 39 is provided with heating amount control means 38, rotation speed control means 41, second air supply amount control means 42, and first air supply amount control means 43. Thus, by introducing a plurality of each control means, the temperature protection of the adsorbent partition 27 can be ensured. In this embodiment, the heating amount control means 38, the rotation speed control means 41, the second air supply amount control means 42, and the first air supply amount control means 43 are all incorporated. It may be carried out only by a few, or some may be selected and carried out.

  With the above configuration, the abnormal state of the adsorbent 109 temperature in the adsorbent partitioning portion 27 of the regeneration chamber 115 is quickly detected, and even if an abnormal state occurs, the deterioration such as deformation of the regeneration chamber 115 and main parts is eliminated and the adsorbent 109 returns.
