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) mainly used in general households, 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 dehumidify by cooling with air, condensing and collecting as condensed water. (For example, see Patent Document 1)
Hereinafter, a conventional dehumidifier will be described with reference to FIG.

  FIG. 9 is a simplified cross-sectional view showing the configuration of a conventional dehumidifier that circulates air used for regeneration and collects it as condensed water. As shown in FIG. 9, the main body 101 of the dehumidifier is provided with a suction port 103 and a main body outlet 104 for the first air 102, and the main body 101 absorbs moisture from the first air 102 in the moisture absorption region 105, thereby generating a regeneration region. 106, the adsorbent 109 that regenerates by releasing moisture to the second air 108 heated by the heating means 107, and the moisture absorption from the first air 102 in the moisture absorption region 105 and the moisture release to the second air 108 in the regeneration region 106 are performed. The driving means 110 that rotates the adsorbent 109 so as to be repeated, and the second air 108 that has flowed out of the regeneration region 106 is cooled by the first air 102, and the moisture release from the adsorbent 109 is recovered as condensed water. The condenser 111, the first air supply means 112 that sucks the first air 102 from the suction port 103 and supplies the first air 102 to the moisture absorption area 105 and the condenser 111, and the heating means 10. , And a second air supply means 113 for circulating the second air 108 in the order of playback area 106, a condenser 111.

  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 from the main body outlet 104 to the outside of the apparatus. 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.

  There is also a type of dehumidifying device that cools and recovers the remaining heat of the heating means 107 held by the adsorbent 109 (see, for example, Patent Document 2).

  FIG. 10 is an explanatory view showing the configuration of a dehumidifying device of the type that cools and recovers the remaining heat of the heating means 107 possessed by the conventional adsorbent 109. As shown in FIG. Heat exchange that exchanges heat between the cooling region 115 that cools the adsorbent 109 with the first air 102 and the first air 102 that has passed through the cooling region 115 and the second air 108 before entering the heating means 107. A vessel 116 is provided. In the cooling region 115, the adsorbent 109 heated by the heating means 107 is rotationally moved while maintaining a high temperature state. The adsorbent 109 in the high temperature state is cooled by the first air 102 supplied to the cooling region 115 and then rotates and moves to the moisture absorption region 105. The first air 102 used for cooling the adsorbent 109 exchanges heat with the second air 108 in the heat exchanger 116. The second air 108 is supplied to the heating means 107 after heat exchange with the first air 102 in the heat exchanger 116.

Therefore, the dehumidifying efficiency in the moisture absorbing portion is improved by lowering the temperature by the first air in the cooling region before the adsorbent rotates from the regeneration region to the moisture absorbing region, thereby obtaining a dehumidifying device having high dehumidifying efficiency. .

  In the conventional dehumidifier described above, when the flow rate of the first air (102) passing through the cooling region (115) passes through the cooling region (115), it is adsorbed by the adsorbent (109) unless the flow rate of the first air (102) passing through the cooling region is reduced. A part of the water content is discharged to the first air (102) and blown out from the dehumidifying device, resulting in a problem that the dehumidifying efficiency is lowered.

  Further, in the moisture absorption region (105), the adsorbent (109) is cooled to the first air (102) having a lower temperature than the second air (108) after passing through the heating means (107), and thus the regeneration region. When rotating to (106), the adsorbent (109) remains in a low temperature state.

There is a problem that it cannot be used for the regeneration of (109) and the dehumidification efficiency cannot be improved.

It is set as the structure formed.

  Further, a ninth problem-solving means taken by the present invention is the above-mentioned eighth problem-solving means, in which the adsorbent facing surface of the casing (13) is molded with a sheet metal (17) to constitute the heat absorbing portion (31). It was decided to do.

  The eleventh problem solving means taken by the present invention is used in the second cooling region (28) in the first, second, third, fourth, fifth, sixth, seventh, eighth or ninth problem solving means. The second air (108) thus obtained is configured to flow into the condenser (111).

  Next, the operation of the problem solving means will be described.

  In the first problem solving means, the adsorbent (109) having a characteristic of absorbing moisture from relatively high humidity air to the dehumidifying device and releasing the moisture to relatively low humidity air is the moisture absorption region (105). And the regeneration region (106) are pivoted so as to be rotated by driving means (110) engaged with the adsorbent (109). The first air supply means (112) supplies the first air (102) to the moisture absorption area (105), and the regeneration area (106) is heated by the second air supply means (113) by the heating means (107). The second air (108) heated to high temperature and low humidity is supplied. Due to the relative humidity difference between the first air (102) and the second air (108), the adsorbent (109) absorbs moisture from the first air (102) having a relatively high humidity, and the second air having a relatively low humidity. A moisture absorption / release cycle is performed to release moisture to (108). The second air (108) that has passed through the regeneration region (106) is guided to the condenser (111), and is cooled to below the dew point temperature by the first air (102) to be dehumidified. The amount of condensed water collected from the second air (108) during this cooling process is the dehumidifying amount of the dehumidifier, and corresponds to the amount of moisture absorbed by the adsorbent (109) from the first air (102). Since the adsorbent (109) is rotated by the driving means (110), moisture absorption from the first air (102) and moisture release to the second air (108) are repeated, and dehumidification is continuously performed. . And the 1st cooling area | region (29) in which the 1st air (102) cools the said adsorbent (109) heated by the said heating means (107), and the said adsorbent heated by the said heating means (107) (109) is provided with a second cooling region (28) in which the second air (108) cools. Thereby, the heated adsorbent (109) can be cooled by the first air (102) and the second air (108) having different air conditions, and the cooling efficiency of the adsorbent (109) is increased.

  Further, in the second problem solving means, in the rotation direction of the adsorbent (109), the adsorbent (109) includes a first cooling region (29), a moisture absorption region (105), a regeneration region (106), and a second cooling. The regions (28) are arranged in this order. Thus, after the regeneration region (106), the adsorbent (109) is first cooled by the second air (108) in the second cooling region (28). Therefore, even if moisture is released from the adsorbent (109) in the second cooling region (28), the second air (108) only circulates in the closed air passage, so that moisture is blown from the dehumidifier into the room. I will not put it out. Thereafter, the adsorbent (109) is sufficiently cooled to the first air (102) in the first cooling region (29), and is then rotated and moved to the moisture absorption region (105) to absorb moisture.

  In the third problem solving means, a preheating region (30) in which the second air (108) preheats the adsorbent (109) is provided. As a result, the preheated adsorbent (109) rotates and moves to the regeneration region (106).

  In the fourth problem solving means, in the rotation direction of the adsorbent (109), the adsorbent (109) includes a first cooling region (29), a moisture absorption region (105), a preheating region (30), a regeneration region ( 106) and the second cooling region (28). As a result, the adsorbent (109) is preheated in advance immediately before it is rotationally moved to the regeneration region (106).

  In the fifth problem solving means, the first air (102) exchanged with the second air (108) in the vicinity of the outlet of the condenser (111) flows into the first cooling region (29). In the condenser (111), the temperature of the second air (108) is highest in the vicinity of the inlet, and as it flows through the condenser (111), it is cooled to the first air (102) and heads toward the outlet. It gets lower gradually. On the other hand, the first air (102) flows into the condenser (111) with a uniform temperature distribution. On the outlet side of the condenser (111), the temperature change in the condenser (111) of the second air (108). As a result, a temperature distribution occurs, and the temperature of the first air (102) that cools the vicinity of the outlet of the condenser (111) of the second air (108) is the lowest. Therefore, the air having the lowest temperature after the first air (102) passes through the condenser (111) can flow into the first cooling region (29), and the adsorbent (109) can be efficiently cooled.

  In the sixth problem solving means, in the fifth problem solving means, the second air (108) flowing out from the condenser (111) flows into the second cooling region (28). After the second air (108) is heated to a high temperature by the heating means (107), it passes through the regeneration region (106) of the adsorbent (109) and receives moisture from the adsorbent (109), and then the temperature is lowered. Then, it flows into the condenser (111), further cooled to the first air (102), gradually lowers the temperature, and reaches the lowest temperature of the second air (108) at the outlet of the condenser (111). As a result, the second air (108) at the outlet of the condenser (111) having the lowest temperature in the second air (108) circulating in the closed air passage can flow into the second cooling region (28), and the adsorbent (109) ) Can be cooled efficiently.

  Further, in the seventh problem solving means, the endothermic heat is absorbed by the second air (108) from the moisture absorption area (105) immediately after the regeneration area (106) of the adsorbent (109) is replaced with the moisture absorption area (105). The second air supply means (113) is provided with the section (31), and the second air (108) that flows out of the condenser (111) and absorbs heat in the heat absorbing section (31) flows into the preheating region (30). It is said. As a result, the second air (108) absorbs heat from the adsorbent (109) while maintaining the high temperature state immediately after switching from the regeneration region (106) to the moisture absorption region (105), and the second air (108) is preheated. By flowing into the region (30), the adsorbent (109) can be preheated without particularly inputting energy.

  In the eighth problem solving means, the second air supply means (113) is a blower (12), and the blower (12) includes a casing (13) and a blade (14), and the inside of the casing (13). The blade (14) is configured to blow air as the blade (14) rotates, and the heat absorption part (31) is formed by the adsorbent (109) facing surface of the casing (13). As a result, the flow path of the second air (108) and the adsorbent (109) to be heat-exchanged face each other, and the heat absorption part (31) is easily exposed to the radiant heat from the adsorbent (109), thereby increasing the heat. The heat absorption part (31) with good exchange efficiency can be created, and there is no need to add components.

  In the ninth problem solving means, a part of the casing (13) is formed of a sheet metal (17) to constitute the heat absorption part (31). Thereby, since the heat absorption part (31) has a high heat transfer capability and is easy to process, the heat absorption part (31) with good heat exchange efficiency can be created at low cost by simple processing.

  In the tenth problem solving means, a part of the casing (13) is formed by the sheet metal (17), and a part of the sheet metal (17) is brought close to the adsorbent (109) by drawing. The heat absorption part (31) is comprised. Thereby, since the endothermic part (31) can be brought closer to the adsorbent (109), the air layer between the endothermic part (31) and the adsorbent (109) can be made thin, and the thermal resistance of the air can be reduced. By reducing, the heat absorption part (31) with better heat exchange efficiency can be created.

  In the eleventh problem solving means, the second air (108) used in the second cooling region (28) flows into the condenser (111). Thus, even when moisture is released from the adsorbent (109) in the second cooling region (28), the second air (108) containing moisture flows into the condenser (111). Therefore, moisture can be condensed in the condenser (111).

  According to the present invention, the adsorbent (109) heated by the heating means (107) is heated by the first cooling region (29) where the first air (102) cools, and the heating means (107). The adsorbent (109) is provided with a second cooling region (28) in which the second air (108) cools the heated adsorbent (109) to the first air (102) having different air conditions. ) And the second air (108), and the cooling efficiency of the adsorbent (109) is enhanced, so that the moisture absorption region (105) of the adsorbent (109) can be efficiently absorbed, and the dehumidification efficiency It is possible to provide a dehumidifying device with improved performance.

  Further, according to the second problem solving means, in the rotation direction of the adsorbent (109), the adsorbent (109) includes the first cooling region (29), the moisture absorption region (105), the regeneration region (106), the first Since the two cooling regions (28) are arranged in this order, the adsorbent (109) is first cooled by the second air (108) in the second cooling region (28) after the regeneration region (106). Therefore, even if moisture is released from the adsorbent (109) in the second cooling region (28), the second air (108) only circulates in the closed air passage, so that moisture is blown from the dehumidifier into the room. I will not put it out. Thereafter, the adsorbent (109) is sufficiently cooled to the first air (102) in the first cooling region (29), and is then rotated and moved to the moisture absorption region (105) to absorb moisture. Therefore, in the moisture absorption region (105), the moisture absorption efficiency of the adsorbent (109) is improved, and a dehumidifying device that improves the moisture removal efficiency can be provided.

  Further, according to the third problem solving means, the preheated adsorbent (109) is provided by providing the preheating region (30) in which the second air (108) preheats the adsorbent (109). Since the rotational movement to the regeneration region (106), the output of the heating means (107) is efficiently used for regeneration of the adsorbent (109) in the regeneration region (106), so that the regeneration efficiency is improved and the dehumidification efficiency is improved. A dehumidifying device can be provided.

  According to the fourth problem solving means, in the rotation direction of the adsorbent (109), the adsorbent (109) is provided with the first cooling region (29), the moisture absorption region (105), the preheating region (30), and the regeneration. By arranging the region (106) and the second cooling region (28) in this order, the adsorbent (109) is preheated in advance immediately before it is rotationally moved to the regeneration region (106). In (106), since the output of the heating means (107) is efficiently used for the regeneration of the adsorbent (109), it is possible to provide a dehumidifier that improves the regeneration efficiency and improves the dehumidification efficiency.

  According to the fifth problem solving means, the first air (102) heat-exchanged with the second air (108) in the vicinity of the outlet of the condenser (111) flows into the first cooling region (29). Yes. In the condenser (111), the temperature of the second air (108) is highest in the vicinity of the inlet, and as it flows through the condenser (111), it is cooled to the first air (102) and heads toward the outlet. It gets lower gradually. On the other hand, the first air (102) flows into the condenser (111) with a uniform temperature distribution, but on the outlet side of the condenser (111), the temperature of the second air (108) in the condenser (111). The temperature distribution is generated under the influence of the change, and the temperature of the first air (102) cooling the vicinity of the outlet of the condenser (111) of the second air (108) becomes the lowest. Therefore, the air having the lowest temperature after the first air (102) passes through the condenser (111) can flow into the first cooling region (29), and the adsorbent (109) can be efficiently cooled. Accordingly, since the sufficiently cooled adsorbent (109) rotates in the moisture absorption region (105), the moisture absorption efficiency of the adsorbent (109) is improved, and a dehumidification device that improves the dehumidification efficiency can be provided. it can.

  Further, according to the sixth problem solving means, the second air (108) flowing out from the condenser (111) flows into the second cooling region (28). After the second air (108) is heated to a high temperature by the heating means (107), it passes through the regeneration region (106) of the adsorbent (109) and receives moisture from the adsorbent (109), and then the temperature is lowered. Then, it flows into the condenser (111), further cooled to the first air (102), gradually lowers the temperature, and reaches the lowest temperature of the second air (108) at the outlet of the condenser (111). As a result, in the second air (108) circulating through the closed air passage, the second air (108) at the outlet of the condenser (111) which is the lowest temperature can flow into the second cooling region (28), Since the adsorbent (109) can be efficiently cooled, the sufficiently cooled adsorbent (109) rotates in the moisture absorption region (105), so that the moisture absorption efficiency of the adsorbent (109) is improved and the dehumidification efficiency is improved. An improved dehumidifying device can be provided.

  Further, according to the seventh problem solving means, the second air (108) absorbs heat from the moisture absorption area (105) immediately after the regeneration area (106) of the adsorbent (109) is replaced with the moisture absorption area (105). The heat absorption part (31) is provided in the second air supply means (113), and the second air (108) that flows out of the condenser (111) and absorbs heat in the heat absorption part (31) flows into the preheating region (30). As a result, the second air (108) is absorbed from the adsorbent (109) while maintaining the high temperature state immediately after the regeneration region (106) is replaced with the moisture absorption region (105), and the second air (108) is absorbed. Since the adsorbent (109) can be preheated even if no energy is input by flowing into the preheating region (30), the adsorbent (109) can be efficiently regenerated and power consumption can be reduced. Possible to provide a dehumidifier capable of improving the dehumidifying efficiency.

  Further, according to the eighth problem solving means, the second air supply means (113) is the blower (12), and the blower (12) includes the casing (13) and the blades (14), and the casing (13) The blade (14) is configured to blow air as the blade (14) rotates, and the heat absorption part (31) is formed by the adsorbent (109) facing surface of the casing (13).

The heat exchange efficiency in (31) is improved, the temperature of the second air (108) flowing into the preheating region (30) is increased efficiently, and the preheating of the adsorbent (109) in the preheating region (30) is more sufficiently performed. At the same time, it is possible to efficiently regenerate the adsorbent (109) in the regeneration region (106). In addition, since it is not necessary to add components, the dehumidifier can be provided which is inexpensive and has a simple configuration and excellent dehumidification efficiency.

  Further, according to the ninth problem solving means, the heat absorbing portion is formed by forming the adsorbent facing surface of the casing (13) with the sheet metal (17) excellent in heat conduction to constitute the heat absorbing portion (31). Since (31) is more susceptible to radiant heat from the adsorbent (109), the heat exchange efficiency is improved.

  Further, according to the tenth problem solving means, a part of the casing (13) is formed of a sheet metal (17) excellent in heat conduction, and a part of the sheet metal (17) is drawn by an adsorbent ( 109) and the heat absorption part (31) are configured to be close to each other, the heat absorption part (31) formed by the sheet metal (17) becomes more susceptible to radiant heat from the adsorbent (109), and further the sheet metal (17). Since a part of the adsorbent (109) is brought close to the adsorbent (109) by drawing, the air layer between the heat absorbing portion (31) formed by the sheet metal (17) and the adsorbent (109) can be thinned, and the heat of the air By reducing the resistance, the heat exchange efficiency during this period is further improved. As a result, the temperature of the second air (108) flowing into the preheating region (30) can be increased efficiently, and the adsorbent (109) in the preheating region (30) can be preheated more sufficiently, and at the same time, the regeneration region The adsorbent (109) in (106) can be efficiently regenerated, and the sheet metal (17) is easy and inexpensive to process, and no new parts are added. In addition, a dehumidifying device having excellent dehumidifying efficiency can be provided.

  Further, according to the eleventh problem solving means, the second air (108) used in the second cooling region (28) is caused to flow into the condenser (111), whereby the second cooling region (28). Even if moisture is released from the adsorbent (109), the second air (108) containing moisture can be collected in the condenser (111), and the moisture can be condensed in the condenser (111). Therefore, it is possible to provide a dehumidifying device having no dehumidifying amount and high dehumidifying efficiency.

(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 configuration diagram 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 main body outlet 104 in a case 1 that forms an outline of a main body 101, and sucks indoor first air 102 into the main body 101 from the suction port 103. First air supply means 112 that blows into the room from the main body outlet 104 is provided. The regeneration unit 2 having the function of heating and regenerating the adsorbent 109 is composed of the regeneration chamber 3 and the heating means 107.

  First, the indoor air to be dehumidified is sucked from the suction port 103 as the first air 102 by the first air supply means 112 and supplied to the condenser 111 to cool and dehumidify the second air 108. Supplied. In the moisture absorption region 105, the first air 102 is absorbed by the adsorbent 109 to become dry air, and is blown out from the main body outlet 104 to the outside of the apparatus. 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.

  The regeneration chamber 3 is provided with a rotation shaft 4 that rotatably supports the adsorbent 109. The adsorbent 109 is fitted at the center of the rotation shaft 4 of the regeneration chamber 3, and the heating means 107 and the regeneration chamber 3 are connected to each other. The rotary shaft 4 and the reproduction chamber 3 are pivoted by screwing a plurality of points on the outer peripheral portion in the circumferential direction. 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 5.

  The adsorbent 109 is formed into a disk by laminating and winding up inorganic paper such as ceramic fiber and glass fiber, or plane paper made by mixing these inorganic fibers and pulp, and corrugated paper, It is composed of one or more kinds of adsorbing materials such as zeolite, silica gel, activated carbon and the like, and has a large number of small pores so that ventilation is possible. When the adsorbent 109 contains a relatively high amount of moisture, when air with relatively low humidity, for example, heated air, passes through, moisture is released into the passing air, and the adsorbent 109 is relatively dried. When air with relatively high humidity, for example, indoor air, passes through, moisture in the passing air is absorbed. An AC inductor motor is used as the driving means 110 that rotates and moves the adsorbent 109. The drive means 110 can easily be driven to rotate by fastening a gear to the shaft of the motor and meshing with a gear provided on the rotor side. The optimum rotation speed at which the adsorption capacity of the adsorbent 109 is maximized needs to be adjusted because it varies depending on the air volume of the first air 102 and the second air 108 and the size of the adsorbent 109, but is generally 20 to 40 revolutions per hour. If adjusted to, adsorption and desorption can be executed in a well-balanced manner.

  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 to the heating means 107 and is arranged on the downstream side in the ventilation direction of the first air 102 of the adsorbent 109, similarly to the heating means 107. The second air supply means 113 and the heating means 107 are connected to each other by fitting so that there is no gap between them, and the second air supply means 113 is fixed by being screwed to the partition plate 5. Normally, a sirocco fan is used for the first air supply unit 112 and the second air supply unit 113, but a propeller fan, a turbo fan, or the like may be used in accordance with the air flow rate or the pressure loss during the air flow.

  A hollow condenser 111 having an inlet pipe 6, an outlet pipe 7, 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 6 and connected to return to the second air supply means 113 from the outlet pipe 7 through the connection duct 8 provided in the partition plate 5 to form the circulation air passage 9. Yes. The condenser 111 has a plurality of vent holes 10 through which air can be ventilated, and the first air 102 blown by the first air supply means 112 is passed through the vent holes 10 to circulate in the condenser 111. 2 The air 108 is condensed with sensible heat cooling below its dew point temperature. Moisture in the second air 108 condensed on the inner surface of the condenser 111 drops downward due to its own weight and is guided from the condenser drain port 114 to the water storage tank 11. The water storage tank 11 can be removed from the main body 101, and the condensed water is treated by draining the stored water.

  The condenser 111 is made of a resin such as PP by blow molding, and has a hollow inside, and the second air 108 flows through the hollowed portion. At the same time, the condenser 111 is formed so that the first air 102 flows outside the condenser 111 and can exchange sensible heat so as not to mix with the second air 108. As a result, the second air 108 is cooled by the first air 102. Note that the condenser 111 is not limited to the above-described resin blow molding, as long as the first air 102 and the second air 108 can be sensible heat exchanged with each other. Etc. may be used.

  FIG. 2 is a configuration explanatory view showing a configuration when the second air supply means 113 is used in the blower 12.

  As shown in FIG. 2, the blower 12 is a sirocco fan in which a blade 14 is housed in a casing 13 and a motor 15 that rotates the blade 14 is attached. The casing 13 is provided with a blowing portion 16 which is an opening through which air is blown, and a sheet metal 17 fixed to the casing 13. The sheet metal 17 is provided with a second air suction port 18. The air blower 12 becomes high temperature due to the heat generated by the adjacent heating means 107, and the second air 108 after dew condensation in the condenser 111 flows in. Therefore, the blower 12 needs to be made of a material resistant to high temperature and humidity. The casing 13 is made of a resin material such as glass fiber reinforced PET resin or PPS resin or a material such as stainless steel so that it can withstand in such an environment. Similarly, the sheet metal 17 is made of a metal such as stainless steel that can withstand a high temperature and humidity environment for a long time and is also resistant to rust. As the flow of the second air 108 (not shown) before and after the blower 12, the second air 108 is first cooled by the condenser 111, and then enters a state near the dew point, that is, near 100% relative humidity. After being sucked in from the second air suction port 18, it is conveyed to the heating means 107 through the blow-out part 16.

  FIG. 3 is an explanatory diagram showing the configuration of the heating means 107.

  As shown in FIG. 3, the heating means 107 is configured by inserting a nichrome heater 20 into a fan-shaped heater case 19 and covering with a heater lid 21. The heater case 19 and the heater lid 21 are made of a material that can withstand the high heat of the nichrome heater 20, for example, stainless steel or iron sheet metal plated with zinc or the like. The heater case 19 is an inflow portion of the second air 108 (not shown) to the heater case 19 and is connected to the blowout portion 16 of the blower 12 used as the second air supply means 113. Is open. The connecting portion 22 and the blowing portion 16 are connected to each other by fitting or screwing. The second air 108 blown from the blower 12 flows into the heater case 19 from the connection portion 22 through the blowout portion 16 of the blower 12 and is heated by the nichrome heater 20 to become high-temperature and low-humidity air. Used for playback.

  FIGS. 4A, 4 </ b> B, and 4 </ b> C are explanatory views showing the state of the second air flowing through the heating means 107.

  FIG. 4A is an explanatory view showing a cross section of the case where the second air 108 flowing through the heating means 107 is configured to purge the adsorbent 109. As shown in FIG. 4A, in the case where the second air 108 can purge the adsorbent 109, a gap is provided between the connecting portion 22 and the nichrome heater 20, and the second air is also released from this gap. 108 is configured to flow out. Next, the flow of the second air 108 and the purge mechanism will be described. The second air 108 sent out from the blower 12 (not shown) is cooled by sensible heat exchange with the first air 102 in the condenser 111 (not shown), and the temperature depends on the air condition. When the dry-bulb temperature of the 1st air 102 is 20 degreeC, it is about 40-50 degreeC in general. First, the 2nd air 108 sent out from the air blower 12 flows in into the heater case 19 from the connection part 22 which is an opening part. The second air 108 that flows through the gap between the connection portion 22 and the nichrome heater 22 without passing through the nichrome heater 20 flows out toward the adsorbent 109 as the purge air 23. On the other hand, the second air 108 that has passed through the nichrome heater 20 from the connection portion 22 regenerates the adsorbent 109 as the regeneration air 24. The regeneration air 24 heated by the nichrome heater 20 is high-temperature air reaching several hundred degrees Celsius, while the purge air 23 is about 80 degrees Celsius although there is a slight temperature increase due to the heat leakage of the Nichrome heater 20. Compared with the regeneration air 24, the air is much cooler. The regeneration air 24 regenerates the adsorbent 109, but at the same time, the adsorbent 109 has a heat of several hundred degrees Celsius. As a result, in the portion immediately after the adsorbent 109 is switched from the regeneration area 106 (not shown) to the moisture absorption area 105 (not shown) by rotation, the adsorbent 109 absorbs moisture only by releasing its own heat. Since this is not performed, waste occurs in the moisture absorption region 105. In the configuration of FIG. 4A, the adsorbent 109 that has been regenerated by the regenerative air 24 and simultaneously has a high temperature is cooled by the purge air 23 having a temperature lower than that of the regenerative air 24. Waste generated in the moisture absorption region 105 can be suppressed low, and the dehumidifying efficiency of the adsorbent 109 can be improved.

  FIG. 4B is a cross-sectional view of the case where the second air 108 flowing through the heating means 107 is configured to preheat the adsorbent 109.

  As shown in FIG. 4B, in the case where the second air 108 can preheat the adsorbent 109, the gap between the connecting portion 22 and the nichrome heater 20 is reduced, and instead the lower portion of the nichrome heater is provided. The second air 108 is configured to flow out at a position far away from the connecting portion 22 while bypassing the above-described configuration. Next, the flow of the second air 108 and the mechanism of preheating will be described. The second air 108 sent out from the blower 12 (not shown) is cooled by sensible heat exchange with the first air 102 in the condenser 111 (not shown), and the temperature depends on the air condition. When the dry-bulb temperature of the 1st air 102 is 20 degreeC, it is about 40-50 degreeC in general. First, the 2nd air 108 sent out from the air blower 12 flows in into the heater case 19 from the connection part 22 which is an opening part. The second air 108 that does not pass through the nichrome heater 20 bypasses the nichrome heater 20 and flows out toward the adsorbent 109 as preheated air 25. On the other hand, the second air 108 that has passed through the nichrome heater 20 from the connection portion 22 regenerates the adsorbent 109 as the regeneration air 24. The regenerative air 24 heated by the nichrome heater 20 is high-temperature air reaching several hundred degrees Celsius, while the preheated air 25 rises in temperature due to the heat leakage of the nichrome heater 20 and is about 100 degrees Celsius. Immediately after the adsorbent 109 is switched from the moisture absorption area 105 (not shown) to the regeneration area 106 (not shown) by the rotation, the temperature of the adsorbent 109 itself is that of the first air 102 after passing through the condenser 111. It has cooled to temperature (approximately 40 ° C). If the regeneration with the regeneration air 24 is performed in this state, the heat of the regeneration air 24 is used to increase the temperature of the adsorbent 109 itself, so that the regeneration region 106 is wasted. In the configuration of FIG. 4B, the preheated air 25 that is hotter than the first air 102 that flows into the adsorbent 109 and is dehumidified is heated in the adsorbent 109 before being regenerated by the regenerated air 24. Since the waste generated in the regeneration area 106 immediately after switching from the area 105 can be suppressed and the adsorbent 109 can be efficiently regenerated, the dehumidification efficiency of the adsorbent 109 can be improved.

  FIG. 4C is an explanatory view showing a cross section of the case where the second air 108 flowing through the heating means 107 is configured to purge and preheat the adsorbent 109.

  As shown in FIG. 4C, in the case where the second air 108 can preheat the adsorbent 109, the gap between the connecting portion 22 and the nichrome heater 20 is secured while the second air 108 is kept under the nichrome heater. The second air 108 is configured to be able to flow around at a position far from the connecting portion 22 by detouring. If comprised in this way, in the heating means 107, it will become possible to perform a purge and preheating simultaneously besides regeneration. Therefore, since the purge air 23 having a temperature lower than that of the regeneration air 24 cools the adsorbent 109 that has been regenerated by the regeneration air 24 and has become a high temperature, waste generated in the moisture absorption region 105 immediately after switching from the regeneration region 106. At the same time, the preheated air 25 that is hotter than the first air 102 that flows into the adsorbent 109 and is dehumidified is heated, so that it is generated in the regeneration region 106 immediately after switching from the moisture absorption region 105. Therefore, it is possible to reduce the waste to be performed and to regenerate the adsorbent 109 efficiently, so that the dehumidifying efficiency of the adsorbent 109 can be improved.

  FIGS. 5A, 5 </ b> B, 5 </ b> C, and 5 </ b> D are explanatory diagrams showing details of the first cooling region 26 and the second cooling region 27.

  FIG. 5A is an explanatory diagram showing the flow of the second air 108 in the dehumidifier when the adsorbent 109 is purged using the heater case 19 having the configuration shown in FIG. is there. As shown in the figure, the second air 108 that has exited the second air supply means 113 flows into the heater case 19 from the connection portion 22 provided in the heater case 19. Here, as shown in FIG. 4A, the second air 108 is divided into purge air 23 and regeneration air 24 that are relatively cool. The regeneration air 24 heated by the nichrome heater 20 is high-temperature air reaching several hundred degrees Celsius, while the purge air 23 is about 80 degrees Celsius although there is a slight temperature increase due to the heat leakage of the Nichrome heater 20. Compared with the regeneration air 24, the air is much cooler. The regeneration air 24 regenerates the adsorbent 109, and the purge air 23 cools the adsorbent 109 heated to a high temperature by the regeneration air 24, and joins them into the condenser 111. At this time, the second air 108 is humid air with a very high dew point. In the condenser 111, the second air 108 exchanges sensible heat with the first air 102 (not shown) flowing outside the condenser 111, reaches the dew point by being cooled, and generates condensed water. The second air 108 condensed at the condenser 111 is then sucked again into the second air supply means 113 from the second air suction port 18 as high-humidity air, and the above operation is repeated.

  FIG. 5B is an explanatory diagram for explaining the temperature state of the first air 102 before and after performing sensible heat exchange with the second air 108 in the condenser 111. As shown in the figure, if it is dehumidified air and the object to be dehumidified is indoors, the first air 102 corresponding to indoor air is applied to the surface of the condenser 111 by the first air supply means 112 (not shown). It passes through the second air 108 flowing inside while performing sensible heat exchange, and flows into the adsorbent 109. Here, when performing sensible heat exchange with the second air 108 in the condenser 111, a temperature difference occurs on the outlet side of the condenser 111 depending on where the first air 102 flows into the condenser 111. That is, the second air 108 is at a high temperature immediately after flowing into the condenser 111. When the 1st air 102 is 20 degreeC, the temperature of the 2nd air 108 which flows in into the condenser 111 is about 60-80 degreeC in general. Since the second air 108 is cooled while performing sensible heat exchange with the first air 102 while flowing in the condenser 111, the second air 108 is cooled to about 40 ° C. when reaching the outlet of the condenser 111. Therefore, when viewed from the side of the first air 102, the first air 26 after the sensible heat exchange with the second air 108 on the side of the condenser 111 where the second air 108 flows is relatively high in temperature. On the other hand, the first air 27 after sensible heat exchange with the second air 108 on the side where the second air 108 flows out of the condenser 111 is relatively low in temperature.

  FIG. 5C shows the direction of rotation of the adsorbent 109 and the first air in the adsorbent 109 when the adsorbent 109 is purged using the heater case 19 having the configuration shown in FIG. It is explanatory drawing showing the relationship between the flow of 102 and the 2nd air. As shown in the figure, when the adsorbent 109 rotates clockwise as viewed from the surface facing the heater case 19, the regeneration air 24 first passes through the regeneration region 106 from the heater case 19 to regenerate the adsorbent 109. Next, the purge air 23 passes through the second cooling region 28, cools the adsorbent 109 that has become high temperature by the regeneration air 24, and then heat-exchanges with the second air 108 in the condenser 111. The adsorbent 109 is further cooled by the first air 27. The adsorbent 109 that has been cooled to a certain degree further rotates, and absorbs moisture more efficiently than the remaining first air 102 in the moisture absorption region 105. Next, the effect of this configuration will be described. The regeneration air 24 heated by the nichrome heater 20 (not shown) is high-temperature air that reaches several hundred degrees Celsius, while the purge air 23 is roughly increased in temperature due to the heat leakage of the nichrome heater 20 but somewhat increased. The temperature is around 80 ° C., and the air is much cooler than the regeneration air 24. The regeneration air 24 regenerates the adsorbent 109, but at the same time, the adsorbent 109 has a heat of several hundred degrees Celsius. As a result, in the portion immediately after the adsorbent 109 is switched from the regeneration area 106 to the second cooling area 28 by rotation, the adsorbent 109 does not absorb moisture only by releasing its own heat. Will be wasted. In this configuration, the adsorbent 109 that has been regenerated by the regenerative air 24 and at the same time becomes a high temperature is cooled by the purge air 23 that is cooler than the regenerative air 24, and is further heat-exchanged with the second air 108 in the condenser 111. Since the first air 27 having a relatively low temperature is cooled, waste generated in the moisture absorption region 105 immediately after switching from the regeneration region 106 can be suppressed, and the dehumidification efficiency of the adsorbent 109 can be improved. it can.

  FIG. 5D shows the entire first air 102 and second air 108 when the dehumidifier is configured so that the adsorbent 109 can also be purged using the heater case 19 having the structure shown in FIG. It is explanatory drawing showing a typical flow. First, the first air 102 will be described. The first air 102 passes through the surface of the condenser 111 while performing sensible heat exchange so as not to mix with the second air 108. The first air 102 after passing through the condenser 111 is transferred from the condenser 111 and the first air 26 after sensible heat exchange with the second air 108 on the side of the condenser 111 where the second air 108 flows. The second air 108 is divided into the second air 108 and the first air 27 after sensible heat exchange on the side where the second air 108 flows out. The former passes through the moisture absorption region 105 of the adsorbent 109 and the latter passes through the first cooling region 29. After that, they merge and are supplied to the room as dehumidified air by the first air supply means 112. Next, the flow of the second air 108 will be described. The air path of the second air 108 is constituted by a closed circuit. The second air 108 sent out from the second air supply means 113 flows into the heater case 19 from the connecting portion 22 provided in the heater case 19, where the regenerated air 24 passing through the nichrome heater 20 and the nichrome heater 20 are supplied. It is divided into purge air 23 that does not pass. The regenerated air 24 regenerates the adsorbent 109 and then flows into the condenser 111 as hot and humid air. On the other hand, the purge air 23 cools the adsorbent 109 heated to the high temperature by the regeneration air 24, merges with the regeneration air 24 after passing through the adsorbent 109, and similarly flows into the condenser 111. Since the regeneration air 24 has a particularly high dew point, in the condenser 111, the regeneration air 24 and the purge air 23 are subjected to sensible heat exchange with the first air 102, dew condensation and dehumidification, resulting in moisture. The second air 108 after the condensation in the condenser 111 flows into the second air supply means 113 again, and the above operation is repeated. With this configuration, even if moisture is released from the adsorbent 109 heated to the regeneration air 24 to the purge air 23, the purge air 23 is always a condenser like the regeneration air 24. Since the sensible heat can be exchanged with the first air 102 and dew condensation is performed by the sensible heat exchange, the moisture can be taken out without waste.

  As described above, the first cooling region 29 in which the first air 102 cools the adsorbent 109 heated by the nichrome heater 20 and the second air 108 in which the second air 108 cools the adsorbent 109 heated by the nichrome heater 20. By providing the cooling region 28, the heated adsorbent 109 can be cooled by the first air 102 and the second air 108 having different air conditions, and the cooling efficiency of the adsorbent 109 is increased. It is possible to efficiently perform moisture absorption in the 109 moisture absorption region 105, and to provide a dehumidifying device with improved dehumidifying efficiency.

  Further, by arranging the first cooling region 29, the moisture absorption region 105, the regeneration region 106, and the second cooling region 28 in this order in the rotation direction of the adsorbent 109, first the second cooling region after the regeneration region 106. At 28, the adsorbent 109 is cooled by the second air 108. Therefore, even if moisture is released from the adsorbent 109 in the second cooling region 28, the second air 108 only circulates through the closed air passage, so that moisture does not blow out from the dehumidifier into the room. Thereafter, the adsorbent 109 is sufficiently cooled to the first air 102 in the first cooling region 29 and then rotated and moved to the moisture absorption region 105 to perform moisture absorption. Therefore, in the moisture absorption region 105, the moisture absorption efficiency of the adsorbent 109 is improved, and a dehumidifying device that improves the moisture removal efficiency can be provided.

  Further, by adopting a configuration in which the first air 102 heat-exchanged with the second air 108 near the outlet of the condenser 111 flows into the first cooling region 29, the temperature of the second air 108 in the condenser 111 is near the inlet. Is the highest, and as it flows through the condenser 111, it is cooled by the first air 102 and gradually decreases toward the outlet. On the other hand, the first air 102 flows into the condenser 111 with a uniform temperature distribution. On the outlet side of the condenser 111, the temperature distribution is affected by the temperature change in the condenser (111) of the second air 108. The temperature of the 1st air 102 which is cooling the condenser 111 exit vicinity of the 2nd air 108 becomes the lowest. Therefore, the air having the lowest temperature after the first air 102 passes through the condenser 111 can flow into the first cooling region 29, and the adsorbent 109 can be efficiently cooled. Thereby, since the sufficiently cooled adsorbent 109 rotates in the moisture absorption region 105, the moisture absorption efficiency of the adsorbent 109 is improved, and a dehumidifying device with improved dehumidification efficiency can be provided.

  Further, by adopting a configuration in which the second air 108 flowing out from the condenser 111 flows into the second cooling region 28, the second air 108 is heated to a high temperature by the nichrome heater 20 and then the regeneration region 106 of the adsorbent 109. The temperature of the adsorbent 109 is reduced by passing through the refrigerant, and then flows into the condenser 111, further cooled by the first air 102 and gradually lowered, and the second air 108 is discharged at the outlet of the condenser 111. The minimum temperature. Thereby, in the second air 108 circulating in the closed air passage, the second air 108 at the outlet of the condenser 111 that has the lowest temperature can flow into the second cooling region 28, and the adsorbent 109 can be cooled efficiently. Therefore, since the sufficiently cooled adsorbent 109 rotates in the moisture absorption region 105, the moisture absorption efficiency of the adsorbent 109 is improved, and a dehumidifying device that improves the dehumidification efficiency can be provided.

  In addition, by causing the second air 108 used in the second cooling region 28 to flow into the condenser 111, even if moisture is released from the adsorbent 109 in the second cooling region 28, the second air containing moisture is contained. Since the air 108 can be collected in the condenser 111 and moisture can be condensed in the condenser 111, a dehumidifying device with high dehumidifying efficiency can be provided without a decrease in the dehumidifying amount.

  FIGS. 6A, 6 </ b> B, and 6 </ b> C are explanatory diagrams showing details of the first cooling region 29 and the preheating region 30.

  FIG. 6A is an explanatory diagram showing the flow of the second air 108 in the dehumidifier when the adsorbent 109 is configured to be preheated using the heater case 19 configured as shown in FIG. 4B. is there. As shown in the figure, the second air 108 that has exited the second air supply means 113 flows into the heater case 19 from the connection portion 22 provided in the heater case 19. Here, as shown in FIG. 4B, the second air 108 is divided into a very high temperature regeneration air 24 and a high temperature preheated air 25. The regenerative air 24 heated by the nichrome heater 20 is high-temperature air reaching several hundred degrees Celsius, while the preheated air 25 rises in temperature due to the heat leakage of the nichrome heater 20 and is about 100 degrees Celsius. Immediately after the adsorbent 109 is switched from the moisture absorption area 105 (not shown) to the regeneration area 106 (not shown) by the rotation, the temperature of the adsorbent 109 itself is that of the first air 102 after passing through the condenser 111. It has cooled to temperature (approximately 40 ° C). If the regeneration with the regeneration air 24 is performed in this state, the heat of the regeneration air 24 is used to increase the temperature of the adsorbent 109 itself, so that the regeneration region 106 is wasted. Thus, since the preheated air 25 heats (preheats) the adsorbent 109 before being regenerated by the regenerated air 24, the adsorbent 109 is efficiently regenerated. The regenerated air 24 and the preheated air 25 are then merged and enter the condenser 111. At this time, the second air 108 is humid air with a very high dew point. In the condenser 111, the second air 108 exchanges sensible heat with the first air 102 (not shown) flowing outside the condenser 111, reaches the dew point by being cooled, and generates condensed water. The second air 108 condensed at the condenser 111 is then sucked again into the second air supply means 113 from the second air suction port 18 as high-humidity air, and the above operation is repeated.

  FIG. 6B shows the direction of rotation of the adsorbent 109 and the first air in the adsorbent 109 when the adsorbent 109 is configured to be preheated using the heater case 19 configured as shown in FIG. It is explanatory drawing showing the relationship between the flow of 102 and the 2nd air. As shown in the figure, when the adsorbent 109 rotates clockwise as viewed from the surface facing the heater case 19, first, the preheated air 25 passes from the heater case 19 through the preheating region 30 of the adsorbent 109, and the adsorbent 109. 109 is preheated. Next, after the regeneration air 24 passes through the regeneration region 106 and regenerates the adsorbent 109, the adsorbent 109 is cooled by the first air 27 that is relatively low in temperature although heat is exchanged with the second air 108 in the condenser 111. That is why. The adsorbent 109 that has been cooled to a certain degree further rotates, and absorbs moisture more efficiently than the remaining first air 102 in the moisture absorption region 105. Next, the effect of this configuration will be described. The preheated air 25 rises in temperature due to a temperature rise due to heat leakage from the nichrome heater 20, and is approximately 100 ° C. Immediately after the adsorbent 109 is switched from the hygroscopic region 105 to the regeneration region 106 by rotation, the temperature of the adsorbent 109 itself cools to the temperature of the first air 102 after passing through the condenser 111 (approximately 40 ° C.). Yes. If regeneration with the regeneration air 24 is attempted in this state, the heat of the regeneration air 24 is first used to increase the temperature of the adsorbent 109 itself, and thus the regeneration region 106 is wasted. As described above, since the preheated air 25 heats (preheats) the adsorbent 109 before being regenerated by the regenerated air 24, the adsorbent 109 is efficiently regenerated, and the dehumidifying efficiency. Can be improved.

  FIG. 6C shows the entire first air 102 and second air 108 when the dehumidifier is configured so that the adsorbent 109 can also be preheated using the heater case 19 having the configuration shown in FIG. 4B. It is explanatory drawing showing a typical flow. First, the first air 102 will be described. The first air 102 passes through the surface of the condenser 111 while performing sensible heat exchange so as not to mix with the second air 108. The first air 102 after passing through the condenser 111 is transferred from the condenser 111 and the first air 26 after sensible heat exchange with the second air 108 on the side of the condenser 111 where the second air 108 flows. The second air 108 is divided into the second air 108 and the first air 27 after sensible heat exchange on the side where the second air 108 flows out. The former passes through the moisture absorption region 105 of the adsorbent 109 and the latter passes through the first cooling region 29. After that, they merge and are supplied to the room as dehumidified air by the first air supply means 112. Next, the flow of the second air 108 will be described. The air path of the second air 108 is constituted by a closed circuit. The second air 108 sent out from the second air supply means 113 flows into the heater case 19 from the connecting portion 22 provided in the heater case 19, where the regenerated air 24 passing through the nichrome heater 20 and the nichrome heater 20 are supplied. It is divided into preheated air 25 that does not pass. The preheated air 25 preheats the adsorbent 109 whose temperature has been lowered by the first air 102, and after passing through the adsorbent 109, the preheated air 25 merges with the regeneration air 24 and flows into the condenser 111 in the same manner. On the other hand, the regeneration air 24 regenerates the adsorbent 109 and then flows into the condenser 111 as hot and humid air. Since the regeneration air 24 has a particularly high dew point, in the condenser 111, the regeneration air 24 and the preheated air 25 exchange sensible heat with the first air 102, and water droplets are produced as a result of dew condensation. The second air 108 after the condensation in the condenser 111 flows into the second air supply means 113 again, and the above operation is repeated. With this configuration, even if moisture is released from the adsorbent 109 to the preheated air 25 by preheating with the preheated air 25, the preheated air 25 always flows into the condenser 111 like the regenerated air 24, Since sensible heat can be exchanged with one air 102, dew condensation can be performed by sensible heat exchange, so that moisture can be taken out without waste.

  As described above, since the preheating region 30 in which the second air 108 preheats the adsorbent 109 is provided, the preheated adsorbent 109 rotates and moves to the regeneration region 106, so that the nichrome heater 20 in the regeneration region 106. Is efficiently used for the regeneration of the adsorbent 109, so that the regeneration efficiency can be improved, and a dehumidifying device with improved dehumidification efficiency can be provided.

  FIGS. 7A, 7 </ b> B, and 7 </ b> C are explanatory diagrams showing details of the first cooling region 29, the second cooling region 28, and the preheating region 30.

  FIG. 7A illustrates the flow of the second air 108 in the dehumidifier when the adsorbent 109 is purged and preheated using the heater case 19 having the configuration shown in FIG. 4C. FIG. As shown in the figure, the second air 108 that has exited the second air supply means 113 flows into the heater case 19 from the connection portion 22 provided in the heater case 19. Here, as shown in FIG. 4C, the second air 108 is divided into a relatively low temperature purge air 23, a very high temperature regeneration air 24, and a high temperature preheating air 25. The regenerative air 24 heated by the nichrome heater 20 is high-temperature air reaching several hundred degrees Celsius, while the preheated air 25 rises in temperature due to the heat leakage of the nichrome heater 20 and is about 100 degrees Celsius. Immediately after the adsorbent 109 is switched from the moisture absorption area 105 (not shown) to the regeneration area 106 (not shown) by the rotation, the temperature of the adsorbent 109 itself is that of the first air 102 after passing through the condenser 111. It has cooled to temperature (approximately 40 ° C). If the regeneration with the regeneration air 24 is performed in this state, the heat of the regeneration air 24 is used to increase the temperature of the adsorbent 109 itself, so that the regeneration region 106 is wasted. Thus, since the preheated air 25 heats (preheats) the adsorbent 109 before being regenerated by the regenerated air 24, the adsorbent 109 is efficiently regenerated. The purge air 23 is about 80 ° C. although there is a slight increase in temperature due to the heat leakage of the nichrome heater 20, and it is air that is much cooler than the regeneration air 24. The regeneration air 24 regenerates the adsorbent 109, and the purge air 23 cools the adsorbent 109 heated to a high temperature by the regeneration air 24, and then merges with the regeneration air 24 and the preheated air 25 and enters the condenser 111. At this time, the second air 108 is humid air with a very high dew point. In the condenser 111, the second air 108 exchanges sensible heat with the first air 102 (not shown) flowing outside the condenser 111, reaches the dew point by being cooled, and generates condensed water. The second air 108 condensed at the condenser 111 is then sucked again into the second air supply means 113 from the second air suction port 18 as high-humidity air, and the above operation is repeated.

  FIG. 7B shows the rotation direction of the adsorbent 109 and the first air in the adsorbent 109 when the adsorbent 109 is configured to be preheated using the heater case 19 having the configuration shown in FIG. It is explanatory drawing showing the relationship between the flow of 102 and the 2nd air. As shown in the figure, when the adsorbent 109 rotates clockwise as viewed from the surface facing the heater case 19, first, the preheated air 25 passes from the heater case 19 through the preheating region 30 of the adsorbent 109, and the adsorbent 109. 109 is preheated. Next, after the regeneration air 24 passes through the regeneration region 106 to regenerate the adsorbent 109, the purge air 23 passes through the second cooling region 28 to cool the adsorbent 109 that has become high temperature by the regeneration air 24, and Next, the adsorbent 109 is further cooled by the first air 27 having a relatively low temperature after heat exchange with the second air 108 in the condenser 111. The adsorbent 109 that has been cooled to a certain degree further rotates, and absorbs moisture more efficiently than the remaining first air 102 in the moisture absorption region 105.

  FIG. 7C shows the first air 102 and the second air 108 in the case where the dehumidifier is configured so that the adsorbent 109 can be purged and preheated using the heater case 19 having the structure shown in FIG. It is explanatory drawing showing the whole flow of. First, the first air 102 will be described. The first air 102 passes through the surface of the condenser 111 while performing sensible heat exchange so as not to mix with the second air 108. The first air 102 after passing through the condenser 111 is transferred from the condenser 111 and the first air 26 after sensible heat exchange with the second air 108 on the side of the condenser 111 where the second air 108 flows. The second air 108 is divided into the second air 108 and the first air 27 after sensible heat exchange on the side where the second air 108 flows out. The former passes through the moisture absorption region 105 of the adsorbent 109 and the latter passes through the first cooling region 29. After that, they merge and are supplied to the room as dehumidified air by the first air supply means 112. Next, the flow of the second air 108 will be described. The air path of the second air 108 is constituted by a closed circuit. The second air 108 sent out from the second air supply means 113 flows into the heater case 19 from the connecting portion 22 provided in the heater case 19, where the regenerated air 24 passing through the nichrome heater 20 and the nichrome heater 20 are supplied. It is divided into purge air 23 that does not pass through and preheated air 25. The preheated air 25 preheats the adsorbent 109 whose temperature has been lowered by the first air 102, and after passing through the adsorbent 109, the preheated air 25 merges with the regenerated air 24 and flows into the condenser 111 in the same manner. 23 cools the adsorbent 109 that has been heated to high temperature by the regeneration air 24, merges with the regeneration air 24 after passing through the adsorbent 109, and flows into the condenser 111 in the same manner. On the other hand, the regeneration air 24 regenerates the adsorbent 109 and then flows into the condenser 111 as hot and humid air. Since the regeneration air 24 has a particularly high dew point, in the condenser 111, the regeneration air 24 and the preheated air 25 exchange sensible heat with the first air 102, and water droplets are produced as a result of dew condensation. The second air 108 after the condensation in the condenser 111 flows into the second air supply means 113 again, and the above operation is repeated.

  As described above, the first cooling region 29, the moisture absorption region 105, the preheating region 30, the regeneration region 106, and the second cooling region 28 are arranged in this order in the rotation direction of the adsorbent 109, so Since the adsorbent 109 is preheated in advance immediately before the rotational movement, the output of the nichrome heater 20 is efficiently used for the regeneration of the adsorbent 109 in the regeneration region 106, so that the regeneration efficiency is improved and the dehumidification efficiency is improved. It is possible to provide a dehumidifying device that improves the above.

  FIGS. 8A and 8B are explanatory views showing the details when the heat absorbing portion 31 is formed on the sheet metal 17 of the blower 12 and brought close to the adsorbent 109.

  FIG. 8A is an explanatory view of the blower 12 as viewed from the front of the second air suction port 18 of the second air 108. As shown in FIG. 8A, the heat absorbing portion 31 is provided on the sheet metal 17 of the blower 12. The heat absorbing portion 31 is a protrusion (surface) that is formed on the surface facing the adsorbent 109 so as to be a surface parallel to the adsorbent 109, and may have any shape as long as there is no problem in processing the sheet metal 17. However, it is preferable to configure along the shape of the sheet metal 17 so that a larger area can face the adsorbent 109. Further, the surface of the metal plate 17 on which the heat absorbing portion 31 is provided is preferably made of a metal having good thermal conductivity, and preferably stainless steel, which is a metal resistant to rust. The heat absorbing portion 31 is disposed so as to be close to the adsorbent 109 (not shown) immediately after the regeneration region 106 (not shown) is replaced with the moisture absorbing region 105 (not shown) by rotation.

  FIG. 8B is a schematic diagram illustrating a mechanism in which the heat absorbing unit 31 transfers heat from the adsorbent 109. As shown in FIG. 8B, the surface constituting the heat absorbing portion 31 is disposed along the surface of the adsorbent 109. The adsorbent 109 immediately after the regeneration area 106 (not shown) is replaced with the moisture absorption area 105 (not shown) by rotation has a high temperature of several hundred degrees Celsius in the vicinity of the surface due to heating by the nichrome heater 20. Even after switching to the hygroscopic region 105 due to heat capacity, it has a high residual heat. On the other hand, the second air 108 passing through the blower 12 is a relatively low temperature of several tens of degrees Celsius due to the sensible heat cooling by the first air 102 in the condenser 111. Heat exchange is performed by bringing the adsorbent 109 close to the region 105 immediately after switching to the region 105, and the second air 108 passing through the blower 12 is heated, and the temperature rises. The endothermic part 31 formed by the sheet metal 17 is more susceptible to radiant heat from the adsorbent 109, and further, a part of the sheet metal 17 is brought close to the adsorbent 109 by drawing, so that the endothermic part 31 formed by the sheet metal 17 and The air layer between the adsorbents 109 can be made thinner, and the heat resistance of the air can be further improved by reducing the thermal resistance of the air. That is, it becomes possible to create preheated air without adding parts. Then, if the second air 108 whose temperature has risen in the heat absorbing portion 31 is used as preheated air using the heater case 19 as shown in FIG. The effect of this can be enhanced. As a result, the temperature of the second air 108 flowing into the preheating region 30 can be increased efficiently, and the adsorbent 109 in the preheating region 30 can be preheated more sufficiently, and at the same time, the regeneration of the adsorbent 109 in the regeneration region 106 can be performed. It becomes possible to carry out efficiently. In order to obtain this effect, the gap between the projection surface of the heat absorbing portion 31 and the adsorbent 109 is preferably 5 mm or less, and preferably 3 mm or less.

  In this way, the second air supply means 113 is provided with the heat absorption part 31 that absorbs heat from the moisture absorption region 105 immediately after the regeneration region 106 of the adsorbent 109 is replaced with the moisture absorption region 105, and flows out of the condenser 111. By adopting a configuration in which the second air 108 that has absorbed heat in the heat absorbing portion 31 flows into the preheating region 30, the second air 108 from the adsorbent 109 that maintains the high-temperature state immediately after the regeneration region 106 is replaced with the moisture absorption region 105. The adsorbent 109 can be preheated without any input of energy by allowing the second air 108 to flow into the preheating region 30 and thus the adsorbent 109 can be regenerated efficiently and consumes less power. It is possible to provide a dehumidifying device that can reduce the dehumidifying efficiency.

  Further, the second air supply means 113 is a blower 12, the blower 12 includes a casing 13 and a blade 14, and the blade 13 is configured to blow air by rotating the inside of the casing 13, and the heat absorbing portion 31 is an adsorbent of the casing 13. 109 is formed by facing surfaces. As a result, the flow path of the second air 108 and the adsorbent 109 to be heat-exchanged face each other, and the heat-absorbing part 31 is more likely to receive radiant heat from the adsorbent 109, thereby improving the heat exchange efficiency in the heat-absorbing part 31. The temperature of the second air 108 flowing into the preheating region 30 is efficiently increased, so that the adsorbent 109 can be sufficiently preheated in the preheating region 30 and at the same time the regeneration of the adsorbent 109 in the regeneration region 106 is efficiently performed. It can be carried out. In addition, since it is not necessary to add components, the dehumidifier can be provided which is inexpensive and has a simple configuration and excellent dehumidification efficiency.

  In addition, the heat absorbing efficiency is improved because the heat absorbing portion 31 is more easily exposed to the radiant heat from the adsorbent 109 by forming the heat absorbing portion 31 by forming the adsorbent facing surface of the casing 13 with the sheet metal 17 excellent in heat conduction. Will improve. As a result, the temperature of the second air 108 flowing into the preheating region 30 can be increased efficiently, and the adsorbent 109 can be sufficiently preheated in the preheating region 30 and at the same time, the adsorbent 109 can be regenerated in the regeneration region 106. Since the sheet metal 17 can be processed efficiently and is easy and inexpensive, it is possible to provide a dehumidifying device that has a simple structure and is excellent in dehumidifying efficiency at a low cost.

  Further, the sheet metal 17 is formed by forming a part of the casing 13 with the sheet metal 17 excellent in heat conduction, and configuring the heat absorbing portion 31 by making a part of the sheet metal 17 close to the adsorbent 109 by drawing. The absorbed heat absorbing portion 31 is more susceptible to radiant heat from the adsorbing material 109, and further, a part of the sheet metal 17 is brought close to the adsorbing material 109 by drawing, so that the heat absorbing portion 31 formed by the sheet metal 17 and the adsorbing material 109 are separated. By reducing the air thermal resistance, the heat exchange efficiency during this period is further improved. As a result, the temperature of the second air 108 flowing into the preheating region 30 can be increased efficiently, and the adsorbent 109 in the preheating region 30 can be preheated more sufficiently, and at the same time, the regeneration of the adsorbent 109 in the regeneration region 106 can be performed. Since the sheet metal 17 can be efficiently processed and is easy to process and inexpensive, and no new parts are added, it is possible to provide a dehumidifying apparatus that has a simple configuration and is excellent in dehumidifying efficiency at low cost. .

  In this embodiment, the nichrome heater 20 is taken as an example of the heating means 107. However, this may be anything as long as the temperature of the second air 108 can be raised and the adsorbent 109 can be regenerated. An electric heater such as a ceramic heater, a sheathed heater, or a radiant heater may be used, and the same effect as that of the nichrome heater 20 can be obtained.

  In the present embodiment, the heat absorbing portion 31 provided on the sheet metal 17 is formed into a convex shape by drawing, but any shape may be used as long as the heat absorbing portion 31 can be brought close to the adsorbent 109 and may be flat. In this case, it is not necessary to perform processing on the sheet metal 17 in order to form the heat absorbing portion 31, and the cost can be further reduced.

  The dehumidifying apparatus according to the present invention provides a more efficient and energy-saving regenerating process of the adsorbent (109) by the heating means (107), and uses an air conditioner using a rotary dehumidifying material (dehumidifying rotor). It is also useful for humidifiers or dryers.
