A panel 13 that can be opened and closed is provided on the right side surface of the main body case 1. One of the intake ports 11 is provided on the front surface side of the main body case 1 in the panel 13.

When the panel 13 is opened, a hollow portion 14 is provided in the main body case 1. The hollow portion 14 is a hole extending in the horizontal direction from the vertically elongated square opening 14a on the right side surface of the main body case 1 to the left side of the main body case 1. An air conditioning portion 3 is provided in the cavity portion 14. The air conditioning portion 3 can be taken out from the inside of the cavity portion 14 to the outside of the main body case 1.

As shown in FIG. 3, the main body case 1 is provided with an air passage 15 for communicating the intake port 11 and the air outlet 12. The air passage 15 is provided with an air conditioning unit 3 (water storage container, filter portion), a blower 2, and an air outlet 12 in this order from the intake port 11.

The blower 2 is provided in the central portion of the main body case, and includes a motor portion 16, a fan portion 17 rotated by the motor portion 16, and a scroll-shaped casing portion 18 surrounding them.

The motor portion 16 is fixed to the casing portion 18.

The fan portion 17 is a sirocco fan and is fixed to a rotation shaft (not shown) extending in the horizontal direction from the motor portion 16. The rotation shaft of the motor unit 16 extends from the back side to the front side of the main body case 1.

The casing portion 18 is provided with a discharge port 19 and a suction port 20. The discharge port 19 is provided on the upper surface side of the main body case 1 of the casing portion 18. Further, the suction port 20 is provided on the back side of the main body case 1 of the casing portion 18. When the fan portion 17 is rotated by the motor portion 16, air is sucked into the casing portion 18 from the suction port 20 of the casing portion 18, and the sucked air is blown out of the casing portion 18 from the discharge port 19.

The air conditioning unit 3 includes a water storage container 21 and a gas-liquid contact portion 22.

The water storage container 21 has a substantially box shape with an opening on the top surface, and has a structure capable of storing water. The water storage container 21 is arranged in the lower part of the main body case 1 and can be attached to and detached from the cavity 14 by sliding in the horizontal direction. The water storage container 21 stores water supplied from the water supply unit 7.

The gas-liquid contact portion 22 is a member that brings the water stored in the water storage container 21 into contact with the indoor air sucked into the main body case 1 by the blower 2. The gas-liquid contact portion 22 has a filter 23, a filter frame 24, and a driving unit (not shown).

The filter 23 is formed in a cylindrical shape, and has a structure in which a hole through which air can flow is provided in the circumferential portion. The filter 23 is attached to the filter frame 24 so that one end of the filter 23 is immersed in the water of the water storage container 21. The filter 23 and the filter frame 24 have a structure that is rotated by a drive unit.

The drive unit includes gears (not shown), and the filter frame 24 is rotated by the rotation of the gears, and the filter 23 is rotated by the rotation of the filter frame 24. Since one end of the filter 23 is arranged so as to be immersed in the water of the water storage container 21, the structure is such that the water and the indoor air are in continuous contact with each other.

The control unit 4 controls the operation of the drive unit, which is the gas-liquid contact portion 22, the rotation speed of the fan unit 17, which is the blower 2, the opening and closing of the first water supply valve 8 and the second water supply valve 9. When the fan unit 17 is rotated by the motor unit 16 of the blower 2, the external air that has entered the main body case 1 from the intake port 11 is sequentially air-conditioned unit 3 (water storage container 21, filter 23), blower 2, and outlet. It is blown out from the main body case 1 via 12.

FIG. 4 is a side view of the main body case 1 and the piping case 10 according to the first embodiment of the present invention, in which the lid is removed from the inspection port 30. Further, FIG. 5 is a schematic view of the main body case 1 and the piping case 10 of the first embodiment of the present invention as viewed from the side.

As shown in FIGS. 2, 3, 4, and 5, the electrolyzed water spraying device is installed on the water supply unit 7 that supplies water to the water storage container 21 and on the upstream side of the water supply unit 7, and controls the water supply. It is provided with a water supply valve 8 and a second water supply valve 9 provided on the water storage container 21 side downstream of the first water supply valve 8 in the water supply unit 7 to control water supply.

The water supply unit 7 is a pipe from the water pipe 25 to pouring water into the water storage container 21. The water supply unit 7 communicates with the water pipe 25 via the first water supply valve 8 and the second water supply valve 9. One end side of the water supply unit 7 is connected to the water pipe 25, and the water in the water pipe 25 flows into the water supply unit 7 from one side of the water supply unit 7. The water that has flowed into the water supply unit 7 is dropped onto the water storage container 21 from the other end side of the water supply unit 7.

The water storage container 21 includes a water amount detecting unit 26 that detects the water level of the water stored in the water storage container 21. The water amount detection unit 26 is composed of a full water detection unit 27, a drought detection unit 28, and a drainage detection unit 29, and detects different water levels.

The first water supply valve 8 and the second water supply valve 9 have a structure capable of stopping the supply of water from the water supply unit 7 to the water storage container 21 or supplying water. An example of the first water supply valve 8 and the second water supply valve 9 is a solenoid valve. This valve mechanism has a configuration in which the valve mechanism opens when a predetermined current flows through the solenoid valve, and closes when a current flows through the solenoid valve. When a predetermined current flows through the solenoid valve, the valve mechanism opens, water flows in the water supply unit 7, and when no current flows through the solenoid valve, the valve mechanism closes and the flow of water in the water supply unit 7 stops.

The first water supply valve 8 and the second water supply valve 9 are controlled by the control unit 4. As an example of water supply, when the control unit 4 detects that the amount of water in the water storage container 21 has not reached a predetermined water level by the drought detection unit 28, it first opens the first water supply valve 8 and then the second. Open the water supply valve 9. In this way, the water pipe 25 and the water supply unit 7 are communicated with each other, and the water in the water pipe 25 is supplied from the water supply unit 7 to the water storage container 21. When a predetermined amount of water is accumulated in the water storage container 21 and the full water detection unit 27 of the water storage container 21 detects a predetermined water level, the control unit 4 closes the first water supply valve 8 and the second water supply valve 9. Specifically, the full water detection unit 27 detects the maximum required amount of water stored in the water storage container 21. The full water detection unit 27 includes a full water float portion 27a having buoyancy and a full water detection portion (not shown) that detects the position of the full water float portion 27a. The full float portion 27a is arranged in the water storage container 21, and the full water detection portion is arranged in the main body case 1 in the vicinity of the full float portion 27a. When the full float portion 27a floats to a predetermined height, the full float detection portion detects the full float portion 27a and sends a signal to the control unit 4.

Upon receiving the signal, the control unit 4 stops the water supply from the water supply unit 7 to the water storage container 21 by controlling the first water supply valve 8 and the second water supply valve 9 of the water supply unit 7.

The structure of the drought detection unit 28 and the drainage detection unit 29 is the same as that of the full water detection unit 27, the drought detection unit 28 includes a drought float portion 28a, and the drainage detection unit 29 includes a drainage float portion 29a. The only difference between the full water detection unit 27, the drought detection unit 28, and the drainage detection unit 29 is the difference in the water level detected by each.

The first water supply valve 8 and the second water supply valve 9 are detachably provided in the water supply unit 7. An inspection port 30 is provided on one side surface of the main body case 1 in the left-right direction of the piping case 10. The inspection port 30 has a removable lid (not shown). When the lid is removed from the piping case 10, the second water supply valve 9 can be replaced from the inspection port 30 which is a vertically long square opening. The first water supply valve 8 is provided outside the piping case 10 and can be replaced.

Subsequently, in the above configuration, the self-diagnosis control of the water supply valve by the control unit 4 will be described with reference to the flowchart of FIG.

In step S01, the control unit 4 proceeds to step S02 when the energization time has passed the first predetermined time. If the energization time has not passed the first predetermined time, the self-diagnosis control of the water supply valve is terminated.

If the drainage detection unit 29 does not detect the predetermined water level in step S02 and determines that the water supply timing is reached, the control unit 4 proceeds to step S03. If the control unit 4 determines that the water supply timing is not reached, the self-diagnosis control of the water supply valve is terminated.

In step S03, the control unit 4 closes the first water supply valve 8 and opens the second water supply valve 9, and proceeds to step S04.

If the drought detection unit 28 detects a predetermined water level by the time when the second predetermined time elapses in step S04, the control unit 4 proceeds to step S05. If the drought detection unit 28 does not detect the predetermined water level even after the lapse of the second predetermined time, the process proceeds to step S06.

In step S06, the control unit 4 closes the first water supply valve 8 and closes the second water supply valve 9, and proceeds to step S07.

In step S07, the control unit 4 closes the first water supply valve 8 and closes the second water supply valve 9, and proceeds to step S08.

If the drought detection unit 28 detects a predetermined water level by the time when the third predetermined time elapses in step S08, the control unit 4 proceeds to step S05. If the drought detection unit 28 does not detect the predetermined water level even after the lapse of the third predetermined time, the process proceeds to step S09.

In step S09, the control unit 4 opens the first water supply valve 8 and the second water supply valve 9 and ends the self-diagnosis control of the water supply valve.

In step S05, the control unit 4 closes the first water supply valve 8 and the second water supply valve 9, and displays an abnormality sign on the display unit 6.

In this way, when either the first water supply valve 8 or the second water supply valve 9 is in the open state and the other is in the closed state, the control unit 4 causes water to flow from the water supply unit 7 to the water storage container 21 and detects the amount of water. When the unit 26 detects an increase in water, it diagnoses that the water supply valve is out of order.

By this self-diagnosis control, when either one of the first water supply valve 8 and the second water supply valve 9 is out of order, it is possible to detect an abnormality and stop the water supply without performing an inspection work by a person. As a result, it is possible to provide an electrolyzed water spraying device directly connected to a water supply with a low risk of water leakage.

The present invention can also be applied to a humidifier directly connected to a water supply and an air purifier with a humidifying function.
