Abstract

PROBLEM TO BE SOLVED: To provide a sink cabinet capable of exhausting the odor drifting in and around a water tank effectively to outside a room. SOLUTION: When a suction exhausting device 13 starts sucking motion, the odor around a water tank 2 is sucked and exhausted from a suction hole 5 provided in the upper part of a tank side wall. Thereby the odor drifting in and around the tank 2 can effectively be exhausted to outside the room. In case this sink cabinet 1 is equipped with an ozone water device 21, the ozone gas emitted from the ozone water to wash or perform sterilization and disinfection of foods, dishes, or the like and accumulating in the tank 2 can be exhausted quickly and effectively, which prevents the ozone gas concentration in the kitchen from rising. It may also be acceptable that a suction duct is installed formed of a suction port opening at the top of the tank 2.

Is connected to an exhaust blower 14 installed on the floor surface by an exhaust hose 15. A tank 16 for reducing intake noise is interposed in the exhaust hose 15. An ozone decomposition catalyst 17 is provided at a connection between the exhaust blower 14 and the exhaust hose 15.

The ozone water generator 21 includes an ozone water generator 22.
, A controller 23, an ozone gas sensor 24 and a flow rate sensor 25, which are integrated into one unit. The ozone gas sensor 24 is installed between the tap water tap 3 and the ozone water tap 4. As shown in the block diagram of FIG. 4, the ozone water generation unit 22 includes the ejector 3
1, an ozone generator 32, a gas-liquid separator 33, and an excess ozone decomposer 34. A raw water supply pipe line for supplying pressurized raw water such as tap water to the ozone water generation unit 22 has one end connected to a tap water pipe (not shown) and the other end opened and closed with the ozone water faucet 4 of the sink 1. A pipe 35 is connected to the cock 4a, and a pipe 36 connects the open / close cock 4a and the ejector 31. When the cock 4 is opened, the supply of raw water to the ejector 31 is started, and when the cock 4 is closed, the supply of raw water is stopped.

A flow sensor 25 is provided in the pipe 36. The ejector 31 and the ozone generator 32 are connected by an ozone gas supply pipe 37. The ozone gas generated by the ozone generator 32 is sucked by the ejector 31 when the raw water passes through the ejector 31, and is mixed and dissolved in the raw water to generate ozone water. The generated ozone water flows into the gas-liquid separator 33, and excess ozone that cannot be dissolved is separated. The separated surplus ozone is decomposed into oxygen by the surplus ozone decomposer 34 and released to the outside. The ozone water supply pipe 38 connects the gas-liquid separator 33 and the ozone water faucet 4. Therefore, when the open / close cock 4a is opened, the raw water is supplied to the ozone generation unit 22, and the generated ozone water is supplied from the ozone water tap 4 to the water tank 2.

The controller 23 comprises a control circuit 41, an exhaust blower driving circuit 42 and an ozone generator driving circuit 43. The control circuit 41 includes a CPU, various memories, an interface, and the like (none of which are shown). Based on detection signals from the ozone gas sensor 24 and the flow rate sensor 25, the exhaust blower 14 and the ozone The operation of the generator 32 is controlled. To the switch circuit 44 of the exhaust blower 14, a manual switch 45 and an automatic operation switch 46 controlled by the controller 4 are connected in parallel.

In the above control program, when the raw water flow rate detected by the flow rate sensor 25 exceeds 2 liters / minute and the ozone gas concentration detected by the ozone gas sensor 24 is 0.06 ppm or less, the ozone generator 32 is turned off. Drive. Therefore, when the ozone gas concentration exceeds 0.06 ppm, the operation of the ozone generator 32 stops. When the ozone gas concentration exceeds 0.06 ppm or when the flow rate of raw water exceeds 2 liters / minute, the suction / exhaust device 13 is automatically operated. The suction and exhaust device 13 is
Even if the above operating conditions are deviated, the forced operation is controlled until the time set by the timer elapses. An appropriate time set by the timer is 2 to 3 minutes.

The intake sound generated from the suction port 5 is reduced by a tank 16 interposed in the exhaust hose 15. The ozone gas around the water tank 2 sucked from the suction port 5 is decomposed by the ozone decomposition catalyst 17 and exhausted from the exhaust blower 14. In this case, the exhaust grill 50 provided at the bottom of the sink 1 and the exhaust blower 14 may be connected by an exhaust duct 70 shown by a two-dot chain line in FIG. . Also, the exhaust blower 14 can be installed under the floor of the kitchen, or an exhaust duct can be provided from under the floor to the outside, and the exhaust blower 14 can be installed outdoors.
