Each element will be specifically described below.

(Description of the kitchen system 10A and the first water storage tank 17A)
First, the kitchen system 10A and the first water storage tank 17A will be described. As shown in FIGS. 5 and 6, the kitchen system 10A includes a water supply unit 11A, a kitchen unit 12A, a drain trap unit 13A, a first storage / drain tank unit 14A, a first purification unit 15A, and a pipe 16A. And have. The kitchen system 10A is connected to the first water storage tank 17A. The water purified by the first purification unit 15A (first purified water) can be temporarily stored in the first water storage tank 17A. The first water storage tank 17A includes a metal fitting for fixing under the floor, a heater for adjusting temperature, various sensors, a power source for transporting water, and the like.

  11 A of water supply parts are examples of the water supply part for kitchen systems of a claim, a water supply part, and a hot water supply part. 11 A of water supply parts supply the tap water provided from the water supply system 100A or the hot water supply system 101A to the kitchen system 10A, or the 1st purified water provided from the 1st water storage tank 17A. 11 A of water supply parts are comprised by the faucet provided with the ultraviolet irradiation (UV irradiation) function, for example. The kitchen unit 12A includes a sink, a drainage groove, and the like. The drain trap part 13A is an example of the kitchen use water discharge part of a claim. The drain trap 13A discharges the water used in the kitchen system 10A or the first purified water. In addition, although there exists the drain trap part 13A and the 1st storage tank part 14A which bent the drain pipe in the S shape, you may provide only the drain trap part 13A indoors. And the structure which installs the 1st storage tank part 14A and the 1st purification | cleaning unit 15A adjacent to the 1st storage tank 17A, or installs integrally may be sufficient. By doing so, it is not necessary to install the first storage / drainage tank portion 14A in the indoor space, and the space from the first storage / drainage tank portion 14A to the first storage tank 17A can be arranged under the floor, which leads to securing of space. If only the replacement part of each filter of the first purification unit 15A is adjacent to the room, the effect that the filter can be easily replaced is not lost.

  A specific configuration example of the kitchen portion 12A and the drain trap portion 13A is shown in FIG. The kitchen unit 12A includes a drain groove 42A and a drain pipe 43A, which are examples of a kitchen use water discharge unit. The drain trap portion 13A is configured to accumulate water in the middle of the drainage path like a trap portion (S-type trap portion) in which a drain pipe of a general kitchen is bent into an S shape. It has the 1st storage tank part 14A at the time of supplying sewage to the 1st purification unit 15A. The first storage / drainage tank portion 14A is connected to the first purification unit 15A. The first purified water purified from the first purification unit 15A is supplied to the purified water flow path 46A connected to the purification circulation system 300A, and the water or hot water that has not been purified in the purification process. The drainage flow path 47A connected to the drainage system 200A is supplied. The trap part of the drain trap part 13A can be appropriately changed to a P-type trap, a U-type trap, a drum trap, a trap or the like according to the direction of drainage, the type of drain port, and the like.

  14 A of 1st storage / drainage tanks are examples of the storage / drainage part of a claim, and a 1st storage / drainage part. The first storage / drainage tank section 14A serves as a buffer section that can temporarily store a certain amount of water in order to prevent the used water (sewage) from flowing back to the kitchen. The waste water in the kitchen system 10A passes through the first purification unit 15A and is drained. Therefore, the drainage in the kitchen system 10A is configured to take more time than discharging water without a filter. Therefore, in order to prevent the user from misunderstanding that the used water is stored in the kitchen system 10A, the first storage tank unit 14A is provided between the kitchen unit 12A and the first purification unit 15A. As a result, the used water flows into the first storage tank 14A, and the user feels that the used water is properly discharged regardless of the time required for purification in the first purification unit 15A. Can be made. Moreover, compared with the structure which connects the kitchen part 12A and the 1st purification | cleaning unit 15A directly, it can reduce that the water after use flows backward into the kitchen part 12A. A drainage channel 45A is provided above the first storage / drainage tank portion 14A. When the first storage / drainage tank section 14A is full of drainage from the kitchen section 12A or exceeds a predetermined amount of water (or more than a predetermined water level) such as 90% of the tank capacity, sewage is discharged from the drainage flow path 45A. Thus, it is possible to prevent the sewage from flowing backward into the kitchen unit 12A. In addition, although the magnitude | size of the 1st storage tank part 14A is arbitrary, it can fully fulfill | perform the role as a buffer part by designing according to the quantity of the water used at the time of kitchen use. In addition, it is anticipated that the 1st storage / drainage tank part 14A will become dirty because the used sewage flows in. Therefore, the first storage / drainage tank section 14A is detachable from the kitchen section 12A, the first purification unit 15A, and the drainage flow path 45A, and has a structure that opens and closes so that the inside can be cleaned. desirable.

  The first purification unit 15A is an example of a purification processing unit and a kitchen use water purification unit in the claims.
