Description

  The present invention relates to a heating / drying apparatus, and more particularly to a hot water heating / drying apparatus using a dehumidifying rotor and a heating / drying system using the heating / drying apparatus.

  Devices have been developed in which a humidifying function or a dehumidifying function is added to a hot water heater using a dehumidifying rotor. For example, the applicant of the present application has proposed a hot water heater with a humidifying function using a dehumidifying rotor in Patent Document 1 (Japanese Patent Application No. 2005-020647). In the invention described in Patent Document 1, the regeneration of the dehumidifying rotor is performed by installing a heat exchanger using warm water in front of the dehumidifying rotor, and the air warmed by the heat exchanger passes through the dehumidifying rotor. Adsorbed moisture is evaporated.

  On the other hand, a humidity control apparatus using a dehumidification rotor is proposed in the invention described in Patent Document 2 (Japanese Patent Laid-Open No. 2001-193966). In the invention described in Patent Document 2, outdoor air is taken in and dehumidified, and dried air is supplied indoors. In addition, the indoor air is taken in, heated with warm water, the moisture adsorbed on the dehumidifying rotor is evaporated with the heated indoor air, and the dehumidifying rotor is regenerated by releasing the moisture outside the room.

  In a device in which a dehumidification rotor is incorporated into such a hot water heating device, regeneration of the dehumidification rotor heats the dehumidification rotor with heat radiated from the hot water to evaporate the moisture adsorbed on the dehumidification rotor. . However, the method of regenerating the dehumidification rotor using the heat of hot water has a problem that the temperature at the time of regeneration is low and the dehumidification rotor cannot be completely regenerated or it takes a very long time to completely regenerate. . It is also conceivable to newly add a heat source such as an electric heater for regeneration of the dehumidifying rotor. However, there is a problem in that the product cost increases and the power consumption increases accordingly.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, it goes without saying that the present invention is not limited to the following examples.

  FIG. 1 is a schematic cross-sectional view of a heating and drying system 1 according to the first embodiment. The heating / drying system 1 includes a heating / drying device 3, a first air passage 11 for sending air dried by the heating / drying device 3 to the press-in A, and a second air for sending air to the dressing room B of the bathroom. The air passage 12, the first air path switch 13 for switching the air sent from the heating and drying device 3 to which of the first air passage 11 and the second air passage 12, and the heating and drying device The hot water warmed in 3 is supplied to the underfloor heating device 14 attached under the floor of the living room C, and the hot water warmed in the heating drying device 3 is attached to the bathroom D in the bathroom dryer 15. It comprises a second hot water / pipe 17 for supplying the air and a controller 18 for controlling the heating / drying system 1.

  The heating / drying apparatus 3 includes two functional units, a blower unit 21 and a hot water supply unit 22. The air blowing unit 21 sucks outside air into the heating / drying device 3 from the air inlet 23, passes through the dehumidifying rotor 31, and sends air from the outlet 24 to the first air passage 11. A part of the dehumidifying rotor 31, the intake fan 25, and air filters 40 and 41 are installed in the blower unit 21. Although not shown, the intake fan 25 operates the intake fan motor to rotate the fan, thereby forcibly taking outside air into the heating / drying device 3 from the intake port 23, passing through the dehumidification rotor 31, and the discharge port 24. The air can be sent out to the first air passage 11. The air that has passed through the dehumidifying rotor 31 is adsorbed with moisture by the dehumidifying rotor 31, and the dried air is sent out to the first air passage 11. In addition, air filters 40 and 41 are provided at the intake port 23 and the discharge port 24, respectively, so as to adhere and remove dust from the air passing through the intake port 23 and the discharge port 24. Furthermore, a temperature sensor 30 for detecting the temperature of the air in the blower unit 21 is attached in the vicinity of the discharge port 24 on the downstream side of the dehumidifying rotor 31. When the temperature of the temperature sensor 30 becomes equal to or higher than the set temperature T, it is determined that the combustion exhaust gas from the hot water supply unit 22 is flowing, and the operation is urgently stopped.

  In the hot water supply unit 22, a heat exchanger 26, a burner 27, a combustion fan 28, an exhaust port 29, and a part of the dehumidifying rotor 31 are installed. By burning the burner 27, the hot water is heated by the heat exchanger 26 and supplied to the first and second hot water pipes 16, 17. As shown in FIG. 3, the supply of hot water to the first and second hot water pipes 16 and 17 can be supplied to an arbitrary place by controlling the on-off valve 56 and the three-way valves 57 and 58. . Although not shown, the combustion fan 28 operates the combustion fan motor to rotate the fan, thereby supplying fresh air for the burner 27 to completely burn, and exhausting the combustion exhaust gas from the exhaust port 29 to the outside. Further, the dehumidifying rotor 31 is installed closer to the exhaust port 29 than the heat exchanger 26. Then, when high-temperature air (combustion exhaust gas) heated by the burner 27 passes through the dehumidifying rotor 31, the moisture adsorbed on the dehumidifying rotor 31 is evaporated and regenerated. Further, the moisture evaporated from the dehumidifying rotor 31 is discharged to the outside together with the combustion exhaust gas of the burner 27.

  FIG. 2 is a cross-sectional view taken along the line X-X ′ of FIG. As shown in FIG. 2, the dehumidifying member 32 of the dehumidifying rotor 31 is a cylindrical long member formed by adhering members bent continuously in a wavy shape on the surface of a flat substrate. In addition, a solid adsorbent having a function of adsorbing moisture is attached to the surface of the flat substrate and the corrugated member. There is no particular limitation on the material used for the adsorbent, but any material having the property of adsorbing moisture may be used. For example, materials normally used for moisture adsorption such as silica gel, zeolite, activated carbon, etc. can be used arbitrarily. Further, a gear 33 is formed along the circumference of the cylindrical circumferential portion of the dehumidifying rotor 31.

  Since the dehumidifying member 32 of the dehumidifying rotor 31 has a shape in which a member bent continuously in a waveform is wound, the circular end surface is formed by a gap between the member bent continuously in the waveform and a flat member. Innumerable air passage holes 34 are formed on the entire end face. In FIG. 2, only a part of the air passage holes 34 is omitted and illustrated. The sum of the air passage holes 34 has a sufficient cross-sectional area, and has a large contact area with the air passing therethrough in the length direction (cylindrical thickness direction). Accordingly, the air containing moisture can pass through the air passage hole 34 of the dehumidifying rotor 31 with almost no pressure loss, and at the same time, the moisture is adsorbed and removed by the adsorbent adhering to the surface portion of the dehumidifying rotor 31. The shape of the air passage hole 34 is not limited to the shape described above, and may be any structure that has a large contact area when air passes and does not easily cause pressure loss. For example, the air passage hole 34 may have a hexagonal honeycomb structure. Good.

  A drive gear 37 is attached to the geared motor 36 and is adjusted to a position that meshes with the gear 33 formed on the outer peripheral surface of the dehumidifying member 32. Therefore, by the rotational drive of the geared motor 36, the dehumidification rotor 31 also rotates continuously or intermittently within the circular surface around the central axis 35 of the circular surface.

  The 1st ventilation channel | path 11 has connected the discharge outlet 24 of the heating-drying apparatus 3, and the ceiling of the insertion A with piping. The first air passage 11 is provided with a first air path switch 13. The first air path switch 13 can switch the air blown from the blower unit 21 to the second blower passage 12 side or the first blower passage 11 side of the first blower passage 11. The second air passage 12 is branched from the first air passage 11 by the first air passage switch 13 and connects the first air passage switch 13 and the ceiling of the dressing room B with a pipe. Therefore, the dry air having the moisture adsorbed by the dehumidifying rotor 31 provided in the blowing unit 21 of the heating and drying apparatus 3 is sent from the discharge port 24 to the first or second blowing passages 11 and 12 and the first air path. By switching the switch 13, the air is blown into any room in the push-in A or the dressing room B. Further, humidity sensors 38 and 39 are provided at the insertion A and the dressing room B so that the humidity in the room can be detected.

  FIG. 3 is a schematic view showing a connection state of piping through which hot water heated by the heat exchanger 26 flows. The first hot water pipe 16 is piped so that hot water circulates between the heat exchanger 26 and the underfloor heating device 14. The first hot water pipe 16 connecting the OUT side of the heat exchanger 26 and the IN side of the underfloor heating device 14 has a second hot water pipe 17 for supplying hot water to the IN side of the bathroom dryer 15. Connected to the first hot water piping 16 that connects the IN side of the heat exchanger 26 and the OUT side of the underfloor heating device 14 is for returning hot water flowing out from the OUT side of the bathroom dryer 15 to the heat exchanger 26. A second hot water pipe 17 is connected. In addition, electric three-way valves 57 and 58 are provided at both connecting portions of the first hot water pipe 16 and the second hot water pipe 17, and by controlling the opening and closing of the electric three-way valves 57 and 58, an underfloor heating device is provided. Hot water can be supplied to one or both of 14 and the bathroom dryer 15. Therefore, the hot water absorbs the heat from the burner 27 by the heat exchanger 26 and dissipates it by the underfloor heating device 14 and the bathroom dryer 15, thereby heating the living room C and the bathroom D and relatively reducing the humidity.

  In addition, a pump 55 and an on-off valve 56 are provided in the middle of the first hot water pipe 16, and the heat exchanger 26, the underfloor heating device 14, and the bathroom dryer 15 are controlled by controlling the pump 55 and the on-off valve 56. Supplying hot water efficiently.

  The heating / drying system 1 is operation-controlled by a built-in controller 18 (control means). The remote controller 42 is for remotely operating the heating / drying system 1 and includes a power switch 43, an operation switch 44, and an air path switch 45. The remote controller 42 and the controller 18 are connected through a signal line 46.

  FIG. 4 is a functional block diagram showing an electrical configuration around the controller 18 in the heating / drying system 1. The controller 18 performs microcomputer control of the heating / drying system 1 in accordance with an operation processing program stored in a memory such as a ROM or an EEPROM. That is, as shown in FIG. 4, the controller 18 receives signals from the remote controller 42, the humidity sensors 38 and 39, and the temperature sensor 30, and in accordance with them, the intake fan 25, the burner 27, the combustion fan 28, and the geared in a predetermined procedure. By controlling the motor 36, the first air path switch 13, the pump 55, the on-off valve 56, and the three-way valves 57 and 58, the press-in A, the dressing room B, the living room C, and the bathroom D are heated and dried.

  FIG. 5 is a flowchart showing the operation of the heating and drying operation of the intrusion A and the dressing room B by the heating and drying system 1. Hereinafter, the process from the start to the end of the heating and drying operation of the intrusion A and the dressing room B by the heating and drying system 1 will be described with reference to FIG. While the operation of the heating / drying system 1 is stopped, the intake fan 25, the combustion fan 28, the burner 27, and the geared motor 36 are stopped, and the first air path switch 13 is switched to the push-in side A. And In addition, it is assumed that the humidity settings of the intrusion A and the dressing room B are set to the humidity C1 and C2, respectively. In the present embodiment, it is assumed that the pushing-in A is preferentially dehumidified over the dressing room B.

  When the operation switch 44 of the remote controller 42 is pressed and turned on, the heating and drying system 1 starts the heating and drying operation according to the flowchart of FIG. When the operation of the heating / drying system 1 starts, first, the burner 27 is ignited (step S11) and the combustion fan 28 is rotated (step S12), and the heat exchanger 26 is started to be heated. Further, the geared motor 36 is operated to rotate the dehumidification rotor 31 (step S13) and the intake fan 25 is rotated to suck the outdoor air into the blower unit 21 (step S14). Here, the controller 18 confirms the priority order of the push-in A and the dressing room B (here, the push-in A is given priority) (step S15), switches the first air path switch 13 and sends it out from the blower unit 21. Air is blown to the indentation A side (step S16) and drying of the indentation A is started. At this time, the air sent out from the blower 21 is dehumidified by the dehumidifying rotor 31, while the dehumidifying rotor 31 is regenerated by the heat of the combustion exhaust gas from the burner 27. During the drying operation of the press-in A, the temperature of the air blown from the discharge port 24 is detected by the temperature sensor 30. If the temperature detected by the temperature sensor 30 is equal to or higher than the set temperature T (Yes in step 17), the heating / drying system 1 determines that the combustion exhaust gas from the hot water supply section 22 is flowing, and stops the operation for safety. . That is, the combustion of the burner 27 is stopped (step S24), the rotation of the combustion fan 28 is stopped (step S25), the operation of the geared motor 36 is stopped, and the rotation of the dehumidifying rotor 31 is stopped (step S26). The rotation of the intake fan 25 is also stopped (step S27), the blowing to the push-in A is stopped, and the operation is stopped.

  In the case of No in step 17, the drying of the press-in A is continued. If the humidity in the press-in A is equal to or lower than the set humidity C1 (Yes in step S18), the first air path switch 13 is switched to blow the air sent from the blower unit 21 toward the dressing room B. (Step S19), drying of the dressing room B is started. During the drying operation of the dressing room B, the temperature of the air blown from the discharge port 24 is detected by the temperature sensor 30. If the temperature detected by the temperature sensor 30 is equal to or higher than the set temperature T (Yes in Step 20), the heating / drying system 1 determines that the combustion exhaust gas from the hot water supply section 22 is flowing in, and in the case of Yes in Step S17. Similarly, steps S24 to S27 are performed, and the operation is stopped for safety. Further, when the humidity of the press-in A preferentially set during the drying operation of the dressing room B becomes equal to or higher than the set humidity C1, the process returns to step S16, and the air sent from the blower unit 21 is switched by switching the first air path switch 13. Is blown to the indentation A side, and the indentation A is dried.

  If the humidity of the intrusion A is equal to or lower than the set humidity C1 and the humidity at the dressing room B is equal to or lower than the set humidity C2 (Yes in step S22), it is confirmed whether or not the operation is completed and the operation is continued. (In the case of No in step S23), steps S16 to S23 are repeated to continue the intrusion A and the changing room B. If an operation end command has been input (Yes in step S23), combustion of the burner 27 is stopped (step S24). Further, the rotation of the combustion fan 28 is stopped (step S25), and the operation of the geared motor 36 is stopped to stop the rotation of the dehumidifying rotor 31 (step S26). Further, the rotation of the intake fan 25 is also stopped (step S27), and the blowing to the push-in A (or the dressing room B) is stopped.

  As described above, according to the heating and drying system 1 of the first embodiment, the dehumidification rotor 31 is regenerated by adsorbing moisture by the blower unit 21 and dehumidifying it, and evaporating the moisture adsorbed by the hot water supply unit 22. . Therefore, dehumidification by the dehumidification rotor 31 and regeneration (humidity release) of the dehumidification rotor 31 can be performed efficiently. Further, since a dedicated heat source for regenerating the dehumidifying rotor 31 is not separately provided, energy saving can be achieved. Further, since the room set with priority is automatically dehumidified when the humidity becomes equal to or higher than the set humidity C1 (or set humidity C2), the humidity can always be kept below the set value. In particular, the intrusion adjacent to the living room has a temperature lower than that of the living room and can cause condensation due to the inflow of moisture from the living room, which may cause mold and decrease the durability of the house. If the indentation is dehumidified, dew condensation in the indentation can be prevented, and generation of mold and deterioration of the durability of the house can be prevented.

  In the first embodiment, the case where the push-in A is preferentially set has been described. However, the change of the push-in A and the change-out place B is merely switched when the dressing place B is preferentially set. In the first embodiment, the two rooms of the close-in A and the dressing room B are dried. However, the number of rooms connected to the heating / drying apparatus 3 may be three or more. In that case, it is only necessary to assign the drying priority to each room and dry it.

  In the heating and drying system 1 shown in the first embodiment, since the air to be blown into the intrusion A and the dressing room B is taken in from outside the room, particularly in winter, cold outdoor air is taken in. It was necessary to warm the air taken in so as not to lower the temperature of B or to lower the temperature. The heating and drying system 2 of Example 2 is proposed in order to solve such a problem. The schematic sectional drawing of the heating drying system 2 of Example 2 is shown in FIG. In addition, below, the same location as the heating drying system 1 of Example 1 is abbreviate | omitted, and it demonstrates centering on a different location.

  In the heating and drying system 2, the air inlet 23 of the heating and drying system 1 and the ceiling portion of the press-in A are connected by a pipe or the like to form a third air passage 52, and the second wind is placed in the middle of the third air passage 52. A path switch 51 is provided, and the second air path switch 51 and the ceiling of the dressing room B are connected by piping or the like. That is, by operating the intake fan and rotating the intake fan 25, the air in the push-in A or the dressing room B can be taken into the blower unit 21. Therefore, since the outdoor cold air is not taken in, there is almost no temperature drop of the intrusion A and the dressing room B. Note that the second air path switch 51 moves in conjunction with the first air path switch 13. That is, the second air path switch 51 is connected to the air inlet 23 side and the push-in A of the air blower 21 if the discharge port 24 side of the air blower 21 and the push-in A are connected in the first air path switch 13. If the discharge port 24 of the blower unit 21 and the dressing room B are connected in the first air path switch 13, the intake port 23 side of the blower unit 21 and the dressing room B are connected. Yes. In addition, it is assumed that the humidity settings of the intrusion A and the dressing room B are set to the humidity C1 and C2, respectively. In the present embodiment, it is assumed that the pushing-in A is preferentially dehumidified over the dressing room B.

  FIG. 7 is a flowchart showing the operation of the heating and drying operation of the intrusion A and the dressing room B by the heating and drying system 2. Hereinafter, the process from the start to the end of the heating and drying operation of the intrusion A and the dressing room B by the heating and drying system 2 will be described with reference to FIG. While the operation of the heating / drying system 1 is stopped, the intake fan 25, the combustion fan 28, the burner 27, and the geared motor 36 are stopped, and the first and second air path switches 13 and 51 are on the side of the push-in A. Assume that it has been switched. In addition, it is assumed that the humidity settings of the intrusion A and the dressing room B are set to the humidity C1 and C2, respectively.

  When the operation switch 44 of the remote controller 42 is pressed and turned on, the heating and drying system 1 starts the heating and drying operation according to the flowchart of FIG. When the operation of the heating / drying system 1 is started, first, the burner 27 is ignited (step S31) and the combustion fan 28 is rotated (step S32) to start heating the heat exchanger 26. Further, the geared motor 36 is operated to rotate the dehumidification rotor 31 (step S33) and the intake fan 25 is rotated (step S34). Here, the controller 18 confirms the priority order of the push-in A and the dressing room B (here, the push-in A is given priority) (step S35), and switches the first and second air path switchers 13 and 51. Then, air is circulated between the blower 21 and the press-in A (steps S36 and S37), and the drying of the press-in A is started. At this time, the air sent out from the blower 21 is dehumidified by the dehumidifying rotor 31, while the dehumidifying rotor 31 is regenerated by the heat of the combustion exhaust gas from the burner 27. During the drying operation of the press-in A, the temperature of the air blown from the discharge port 24 is detected by the temperature sensor 30. If the temperature detected by the temperature sensor 30 is equal to or higher than the set temperature T (Yes in step 38), the heating / drying system 2 determines that the combustion exhaust gas from the hot water supply section 22 is flowing, and stops the operation for safety. . That is, the burner 27 is stopped (step S46), the rotation of the combustion fan 28 is stopped (step S47), the operation of the geared motor 36 is stopped and the rotation of the dehumidifying rotor 31 is stopped (step S48), and the intake fan The rotation of No. 25 is also stopped (step S49), and the blowing to the push-in A is stopped.

  In the case of No in step 38, the drying of the push-in A is continued. If the humidity in the press-in A is equal to or lower than the set humidity C1 (in the case of Yes in step S39), the first and second air path switches 13 and 51 are switched between the blower unit 21 and the dressing room B. Air is circulated (steps S40 and S41), and drying of the dressing room B is started. During the drying operation of the dressing room B, the temperature of the air blown from the discharge port 24 is detected by the temperature sensor 30. If the temperature detected by the temperature sensor 30 is equal to or higher than the set temperature T (Yes in step 42), the heating / drying system 2 determines that the combustion exhaust gas from the hot water supply section 22 is flowing, and if Yes in step S38. Steps S46 to S49 are performed in the same manner as described above, and the operation is stopped for safety. Further, when the humidity of the press-in A preferentially set during the drying operation of the dressing room B becomes equal to or higher than the set humidity C1, the process returns to step S36, and the first and second air path switches 13 and 51 are switched to blow the air The air sent out from 21 is blown to the indentation A side, and the indentation A is dried.

  If the humidity at the dressing room B is equal to or lower than the set humidity C2 (Yes in step S44), the presence / absence of the operation is confirmed. If the operation is continued (No in step S45), steps S36 to S45 are performed. Is repeated and the drying of the intrusion A and the dressing room B is continued. If the operation end command is input (Yes in step S45), the burner 27 is stopped (step S46). Further, the rotation of the combustion fan 28 is stopped (step S47), and the operation of the geared motor 36 is stopped to stop the rotation of the dehumidifying rotor 31 (step S48). Further, the rotation of the intake fan 25 is also stopped (step S49), and the blowing to the push-in A (or the dressing room B) is stopped. In the first embodiment, the case where the push-in A is preferentially set has been described. However, the change of the push-in A and the change-out place B is merely switched when the dressing place B is preferentially set.

  Therefore, in the heating and drying system 2, since outdoor air is not taken in, an arbitrary room can be dried without lowering the room temperature in winter or the like.
