Description

  The present invention relates to a water purifier.

  Conventionally, the water supply method to the dishwasher has been to supply water by attaching a dedicated branch fitting to the water tap by water pipe construction, and connecting the dedicated branch fitting and the dishwasher body with a water supply hose. However, in apartments and rental apartments, it is often forbidden or changed to make changes to existing objects, and piping work for attaching the above-mentioned dedicated branch fittings cannot be performed. Even if I wanted to buy, I had to give up buying.

  Therefore, a dishwasher has been proposed in which a branching mechanism is attached to the faucet of the water tap and water is supplied directly from the faucet to the dishwasher. This unit connects the branch mechanism and the dishwasher with a water supply hose, and operates the handle of the branch mechanism to switch the water flow path that is discharged from the faucet into the kitchen sink to the water flow path that flows to the water supply hose. The water supply to a machine is enabled (refer patent document 1).

  When water is supplied to the dishwasher using the branch mechanism, during the washing operation of the dishwasher, the water supply operation such as the supply of wash water and the supply of rinse water is performed multiple times, so the branch mechanism is always used during the wash operation. Therefore, it is necessary to switch to the dishwasher side. During this time, water cannot be discharged from the faucet to the sink, which may cause inconvenience for the user.

  In addition to the tank-type dishwasher described above, a so-called tank-type dishwasher is provided in which a tank for storing washing water for one dishwashing is arranged in the dishwasher, and the washing water is supplied from the tank without using a dedicated branch fitting. Has been proposed. Before washing with a dishwasher, remove the tank from the dishwasher, bring the faucet to the faucet, supply water from the faucet into the tank, and when it is full, set the tank in the dishwasher. Cleaning of tableware is started (see Patent Document 2).

  In this tank type dishwasher, water discharged from the faucet can be used even during washing operation, but it is necessary to remove the tank from the dishwasher, supply water, and set it in the dishwasher again, which is troublesome for the user. Become. Furthermore, even the cleaning water used at one time requires about 10 liters, so that it requires power to carry and has the disadvantage of being a little heavy labor.

Furthermore, today, with the pollution of rivers, harmful substances such as residual chlorine and trihalomethane contained in tap water are attracting attention, and interest in water safety is increasing. For this reason, in each household, a water purifier of a water purification cartridge type that can be replaced when dirt is accumulated has been installed in a pipe or faucet opening of a water tap (see Patent Document 3).
JP 2001-57956 A Japanese Patent Laid-Open No. 2000-245679 JP-A-11-104628

  In order to be able to use the water discharged from the faucet faucet even during the washing operation of the dishwasher by the method of directly supplying water to the dishwasher from the above-mentioned faucet, the tank and faucet branching mechanism used in the tank type dishwasher Can be connected with a water supply hose to supply cleaning water to the tank. By doing so, there is no need to remove the tank, and it is not necessary to carry a tank storing a lot of water.

  However, when the water purifier is already attached to the faucet opening, it is not assumed that the above branching mechanism is attached in addition to this water purifier, and the water purifier and the branching mechanism are not attached. In addition, when a water purifier is attached to the plumbing pipe, water that has been purified by the water purifier need only be used as potable water, and if it is used for washing dishes, dirt accumulated in the water purification cartridge will also increase. However, the replacement time of the water purification cartridge is advanced, which causes the running cost to increase.

  The present invention has been made to solve the above-described problems.

  A water purifier according to the present invention made to solve the above-mentioned problems is connected to a faucet of a water faucet, purifies the water introduced from the faucet connection port, a faucet connection port for introducing water from the faucet.

Lever corresponding to diverter of the present invention that the turning operation, 47 is a cartridge water outlet 47 provided on the lower surface of the purification cartridge 38a to eject water purification water in water purification cartridge 38a.

  48 is a book that, in conjunction with the operation of the lever 46, switches the communication path so that any one of the first water outlet 43, the second water outlet 44, or the purified water outlet 45 and the water inlet 45 communicate with each other. The switching mechanism 49 corresponding to the water channel switching unit of the invention is arranged in the water channel between the switching mechanism 48 and the first outlet 43, and suppresses the water amount when a certain amount or more of water flows. A constant flow valve for dishwasher 50, which is less than a certain amount, is arranged in the water passage between the switching mechanism 48 and the purified water outlet 45, and suppresses the amount of water when more than a certain amount of water is about to flow. It is a constant flow valve for water purifiers that does not exceed a certain amount.

  In the above description, the constant flow valve 49 for the dishwasher is provided in the water purifier 38, but is not limited thereto, and may be provided in the dishwasher body 1, for example, in the water supply connection pipe 23. You may provide in the middle of the water supply hose 39. FIG.

  The reason for providing the constant flow valve 49 for the dishwasher is as follows. When the water from the water tap 36 is directly supplied into the washing cabinet 3 of the dishwasher main body 1, even if the water pressure of the water tap 36 is different, the water supply water level is controlled by the control of the water level sensor 20 provided in the dishwasher main body 1 and the control circuit. It can flexibly cope with management and when the water level rises to an abnormal level. However, in the so-called tank-type dishwasher in which the water is stored once in the water storage tank 22 of the dishwasher main body 1 and washed as in the present embodiment, the water tap 36 is used when the water storage tank 22 is full for the user. If the water tap 36 is kept open, the water supplied from the water storage tank 22 overflows. The amount of overflowing water is difficult to assume when designing the dishwasher due to variations in the water pressure of the water tap 36, and it is difficult to design the overflow amount of the overflow pipe 24 to be an appropriate amount. If the water pressure of the water tap 36 is high and the amount of water supply is larger than the expected amount, the water storage tank 22 cannot overflow well, and the water storage tank 22 may be deformed by the water pressure. As a result, the overflow pipe 24 becomes larger and the amount of water that can be stored in the water storage tank 22 is reduced. Therefore, the size of the overflow pipe 24 is limited. Therefore, if the constant flow valve 49 for the dishwasher is provided so that the amount of water supplied to the water storage tank 22 is constant, the amount of overflow from the overflow pipe 24 can be designed with an appropriate amount at the time of design, and the water storage tank 22 is deformed. Therefore, a sufficient amount of water stored in the water storage tank 22 can be secured.

  5 to 7 show the internal mechanism of the water purifier 38. FIG. Details will be described below.
