[0016]

By the way, the blower 60
Since the air supplied from the blower 60 generates heat from the blower 60, the heated air is supplied from the blower 60 to the air flow switching device 70. Here, when a large amount of moisture is contained in the air taken in by the blower 60 (for example, in the case of a configuration in which the blower 60 takes in air from outside the water treatment device, the humid outside air in rainy weather, In the case of a configuration in which the air is taken in from the inside, the air from the blower 60 becomes hot and humid.

When the high-temperature and high-humidity air flows into the air flow path switching device 70 at room temperature, the temperature difference causes the gap between the rotor 71 and the housing lid 72c and the side slope 71b of the rotor 71 to be removed.
If the dew water is generated between, for example, the inner slope 72b of the housing 72 and the water droplets w flow down and adhere to the electric components such as the photo sensor 76 and the motor 73, the malfunction of the air flow path switching device 70 is caused. In addition to the failure, the rotor 71 may come into close contact with the housing 72 due to the surface tension effect of water and the air flow path may not be switched.

In the above configuration, since the blower 60 and the air flow path switching device 70 are directly connected, the blower 60
(Including a low-frequency vibration sound) propagated to each pipe via the air flow path switching device 70, causing noise in the entire water treatment apparatus. If soundproofing measures are taken for each pipe in order to prevent this noise, the number of parts for soundproofing measures increases, the installation space increases, the water treatment apparatus becomes larger, and the cost also increases.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing a main part of an embodiment of the present invention. The same reference numerals as those in FIGS. 8 and 9 denote the same or corresponding parts.

In this embodiment, first, the air flow path switching device 7
The motor 73, the photo sensor 76, and the like, which are the 0 electrical components, are arranged above the rotor 71 and the housing 72. That is, the air flow path switching device 70 shown in FIG. 9 is arranged upside down.
Even with this configuration, when the blower 60 shown in FIG. 8 is operated to start air supply, the rotor 71 floats upward against the gravity due to the air pressure of the air supply, and as a result, the inside of the housing 72 The side slope 71b of the rotor 71 is pressed against the slope 72b, so that no air leakage occurs.

The blower 60 and the air flow switching device 7
0, a large-capacity cylindrical heat exchange chamber 100 having both a heat exchange function and a silencing function is provided.
Are integrated with the upper wall surface of the electrical component chamber 78 of the air flow switching device 70. In this heat exchange chamber 100,
A heat exchange plate 104 is formed between the inlet 102 and the outlet 103 of the air from the blower 60 so as to alternately communicate with each other so as to increase the contact area with the inflow air.

The bottom surface 101 of the heat exchange chamber 100 is an inclined surface descending toward the discharge port 103, and the heat exchange plate 104 also has an open end inclined toward the discharge port 103 to remove dew condensation water. They are collected and guided to the storage unit 120 via a pipe 110 extending downward from the discharge port 103. In addition, the drainage valve 1 is provided in the storage unit 120.
30 is provided, and is configured to be able to drain to any tank of the water treatment apparatus. The pipe 110 branches off in the horizontal direction from the middle and is connected to an air inlet H0 formed in the housing lid 72c of the air flow switching device 70.

In the above configuration, the air sent from the blower 60 passes through the heat exchange chamber 100, and then is sent to the air inlet H 0 of the air flow switching device 70, and is passed through the rotor 71 by the rotor 71. The air is discharged to any one of the air outlets of the selected housing 72 (air outlet H5 in the figure).

With such a configuration, in a condition where dew condensation is likely to occur, for example, when the water treatment apparatus is installed outdoors in winter, the heat exchange chamber 100 and the air flow path switching device 70 may be used.
When the ambient temperature at which is installed is low, the high-temperature and high-humidity air sent from the blower 60 is reduced in temperature while passing through the heat exchange chamber 100, as shown in the psychrometric chart of FIG. When it becomes humid air, excess moisture condenses and is collected in the storage part 120 by the inclined bottom surface 101 of the heat exchange chamber 100.

Further, since the electric component room 78 of the air flow switching device 70 is adjacent to the heat exchange room 100 with one wall interposed therebetween, heat is directly transmitted from the heat exchange room 100 to be heated. As a result, the temperature of the air from the blower 60 decreases while passing through the heat exchange chamber 100 as shown in FIG.
0, the temperature is almost the same as that of the electric component room 78, and thus the motor 73 and the photo sensor 76. As a result, no dew condensation occurs inside the air flow path switching device 70.

Further, for some reason (the air flow switching device 7)
Even if the condensed water is generated in the housing 72 of the air flow path switching device 70 due to, for example, 0 not sufficiently warmed), it does not reach the electric component room 78 on the upper side thereof and is shown in FIG. As described above, the water droplets w pass through the air inlet H of the air flow switching device 70.
It is returned to the 0 side and is also sent to the storage unit 120.

The reservoir 120 is provided with a manual drain valve 130 for periodically draining the accumulated water. When the valve 130 is opened, the drain is drained to any tank in the water treatment apparatus. Therefore, it is possible to prevent the dew water from being discharged to the outside.

It should be noted that the valve 130 should not be overlapped with the time for supplying air to each tank, and should be opened and drained periodically when the blower 60 is stopped using an automatically operated valve. Thus, automation may be considered so as not to affect the control of the water treatment system.

Further, the heat exchange chamber 100 is provided with a blower 60
Is formed in a structure having a muffler effect for silencing the noise (including low-frequency vibration sound), so that it can be silenced before entering the air flow switching device 70, and as a result, extends from the air flow switching device 70 Since it is not necessary to attach a soundproofing device for each pipe, soundproofing measures can be simplified, the required installation space for parts is reduced, and the water treatment device can be downsized.
Further, a cost reduction effect can be obtained.

In this embodiment, the electric components are extended from the top surface to the side surfaces so as to further eliminate the difference between the temperature of the air sent from the blower 60 and the internal temperature of the electric component chamber 78 in the air flow switching device 70. The heat exchange chamber 100 is arranged so as to cover the chamber 70.

The heat exchange plate 104 is provided at the bottom of the heat exchange chamber 100 (including the top of the electric parts chamber 78) 101 so as to improve the heat exchange efficiency and to allow the dew water to flow smoothly to the outlet 103. And is formed so as not to contact the bottom surface 101 around the electric component chamber 78.
