Description

  The present invention relates to a water purifier and a dishwasher provided with a flow restricting member that restricts the flow rate.

  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 the 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 the 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 a lot of power to carry and has the disadvantage of being a little heavy labor.
JP 2001-57956 A Japanese Patent Laid-Open No. 2000-245679

  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.

  In addition, when water is supplied to the tank via the water supply hose, if the user leaves the place during the water supply, the water supply will continue without stopping even if the tank is full, and there will be an allowable amount in the tank. If the above water is supplied, the water pressure in the tank rises and the tank may be deformed or ruptured. In order to avoid this, in general, an overflow mechanism is provided in the tank, and an overflow mechanism is provided that drains water outside the tank even if the tank is supplied with water exceeding an allowable amount.

  However, it is known that the water pressure in the water tap varies greatly depending on the environment such as the region, season, installation conditions such as high-rise buildings and detached houses. For this reason, the amount of water supplied to the tank per unit time depends on the water pressure of the tap. The amount of water supplied to the tank also depends on the degree of opening of the water tap.

  For this reason, the overflow mechanism is designed on the assumption that the amount of water drained to some extent. However, if the drainage amount is set to be large, the overflow mechanism will be increased accordingly, and the amount of storage in the tank will be limited. . On the other hand, if the amount of drainage is assumed to be small, when the water pressure of the tap increases and the water supply amount increases, the water will not be sufficiently drained from the overflow mechanism, and the water pressure in the tank will rise, causing deformation or rupture of the tank. It becomes.

  In addition to tank-type dishwashers, even when water is supplied to water-related equipment such as alkaline ionized water conditioners, if the water supply is guaranteed to be below a certain level, the water supply can be assumed at the time of design. Even safer designs are possible.

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

  The water purifier according to the present invention made to solve the above problems is connected to a faucet of a water tap, a faucet connection port for introducing water from the water tap, and water introduced from the faucet connection port to an external device External device discharge port that discharges to the water supply port, purified water discharge port that discharges water introduced from the faucet connection port to the water purification unit, and raw water discharge port that directly discharges water introduced from the faucet connection unit to the outside An external device water passage communicating with the external device outlet, a purified water passage communicating with the purified water discharge port, a raw water passage communicating with the raw water outlet, the external device water passage and the purified water passage And the raw water passage and the faucet connection port can be selectively switched and communicated, and at least one of the external device discharge port and the external device passage can be used for the amount of water flow. Install a flow restriction member to restrict It is characterized in that was.

  In addition, a dishwasher according to the present invention, which has been made to solve the above-mentioned problems, includes a washing room for storing dishes and washing the tableware by spraying washing water onto the dishes, and the washing water washed in the washing room. A storage tank for storing, a water supply port provided for supplying water from the water tap in the storage tank, a water supply channel connecting the water supply port and the water tap, and the water tap for supplying water to the storage tank In order to limit the amount of water supply, a flow rate limiting member provided in the water supply port or the water supply channel is provided.

  According to the water purifier of the present invention, the flow restriction can be performed even if the water-circulating device is not a flow restriction compatible device.

  Moreover, according to the dishwasher of this invention, a water supply flow volume can be restrict | limited and the design of a safe apparatus is attained.

The water outlet 44 is a second water outlet corresponding to the raw water outlet of the present invention provided on the lower surface of the casing 40, and 441 is equivalent to the raw water passage of the present invention communicating with the switching mechanism 48 and the second outlet 44 described later. The raw water communication pipe 45 has a configuration that allows the water purification cartridge 38a to be detachable for replacement of a new one, and a water purification outlet corresponding to the water purification outlet of the present invention communicating with the water purification cartridge 38a, 451 is a switching mechanism. The water purifying communication pipe corresponding to the water purifying water passage of the present invention that communicates 48 with the water purifying cartridge 38 a, 46 is one of the first water outlet 43, the second water outlet 44, and the purified water outlet 45 and the water inlet 41. Lever operated to rotate in order to switch so as to alternatively communicated, 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 corresponding to the flow restricting member of the present invention, which is less than a certain amount, is disposed in the water passage between the switching mechanism 48 and the purified water outlet 45, so that a certain amount or more of water flows. It is a constant flow valve for water purifiers that suppresses the amount of water and keeps it below 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.

  52 is formed of opposed circular flat surfaces 53, 54 and a hollow cylindrical side wall 55, and is a cylindrical branched water channel constituting a switching mechanism 48, and 56 is for guiding water from the water inlet 41 to the branched water channel 52. A water inlet pipe integrally formed with the resin case 40, 57 is formed of a member different from the resin case 40 and the like, and corresponds to the water supply device water passage of the present invention in which the branch water passage 52 and the first discharge port 43 are communicated. A first communication pipe 58 is a water purifier communication pipe corresponding to the water purification water passage of the present invention that communicates the branch water path 52 and the water purifier discharge port 45. A constant flow valve 49 for a dishwasher is arranged inside the first communication pipe 57 to adjust the amount of water flowing in the communication pipe.

  The cylindrical side wall 55 of the branch water channel 52 has a water inlet 59 that communicates with the water inlet 56, a first inlet 60 that communicates with the first inlet 57, and a second outlet that communicates with the second outlet 44.
