Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a water faucet that can be attached to household sinks, etc., and is particularly applicable to water purification. This relates to a water faucet with functions.

0002

[Conventional technology]

Calcium, bad odor, red rust, mold, bacteria, and harmful substances dissolved or mixed in tap water Traditionally used for example on sink faucets used for drinking purpose to remove impurities such as In some cases, water purifiers were installed.

0003 By the way, conventional water purifiers are cylindrical plastic purifiers as shown in Figure 11. Filter media such as activated carbon, hollow fiber membrane filter, calcium ceramics, etc. are installed in the water container body a. is accommodated, and the water purifier body a is placed on the sink b, and the water outlet pipe f of the faucet c is Screw the switching valve d to the switch valve d, and connect the water purifier main body a to the branch port provided on the switching valve d. By connecting the tip of the hose e that has come out and operating the lever g of the switching valve d, The hot water that comes out of the water outlet pipe f passes through the hose e and the water purifier main body a, and is filtered to become purified water. The filtered water is discharged through a water discharge pipe h provided in the vessel body a. If you switch the lever g, the hot water in the water pipe f will be switched directly without passing through the water purifier body a. Water can also be spouted from the lower surface of the valve d.

0004 Furthermore, in the conventional water purifier shown in FIG. It is designed to be fixed in place, and in this case as well, the above switching can be done by operating lever g. is now possible.

[0005]

[Problem that the idea aims to solve]

By the way, the water purifier shown in FIG. 11 has the following problems. (b) The hose e and the water purifier main body a occupy a narrow space in the sink and interfere with kitchen work. It can become a nuisance and make cleaning difficult, resulting in unsanitary conditions. (b) Because of the hose e, the water discharge pipe f cannot swing freely. (c) A soft hose must be used to make it easier for the water discharge pipe f to swing. However, if this happens, the heat resistance and pressure resistance will be lost, and hot water will not be passed through. There is a risk of damage when water pressure increases due to clogging of filter media, etc. Ru. Furthermore, the water purifier shown in FIG. 12 has the following problems. (d) The space between the sink and the outlet becomes narrower, making it impossible to fit large containers. . (e) Since the water purifier main body a is heavy, it is difficult to swing the water discharge pipe f, and the space is also limited. narrow the inside of the tank. (f) The sealing part of the connection part of the discharge pipe f on the secondary side of the water supply faucet c is originally pressure resistant. If the filter material becomes clogged, the water pressure in the water discharge pipe f will increase and water leakage will occur. There is a risk of this happening.

[0006] Furthermore, the above two examples of conventional water purifiers have the following problems in common. (g) The water purifier spout is blocked due to the filter media becoming clogged or some other reason. When this happens, all the water supply pressure is applied to the water purifier body a, and the pressure difference between it and the atmospheric pressure is the water purifier body a. Since it is applied to the vessel wall of body a, the vessel wall is expanded and deformed or damaged. this thing This may become more noticeable when hot water is supplied, and for this reason, do not run boiling water. I couldn't do it. (H) A safety valve attached to the water purifier body a to release the pressure inside the water purifier body a. However, this would not only complicate the structure, but also cause water leakage from the safety valve to cause damage to the surrounding area. As illustrated in Fig. 11, a hose j for getting wet or draining water leakage is shown in Fig. 11. There are drawbacks such as the fact that it has to be installed. (li) If the water purifier is not used for a while, the remaining water in the water purifier body a will rot. , it becomes unsanitary. Especially with these types of water purifiers, air can easily enter into the water purifier body a. If this happens, using a water purifier may actually lead to unsanitary conditions as bacteria can easily grow inside the container. There was even one.

[0007]

[Means to solve the problem]

The faucet with a water purifier of this invention attempts to solve the above problem, and the faucet itself is A water purification cart in which a chamber is formed integrally with the faucet main body in the flow path and a filter medium is enclosed. A ridge is replaceably installed in the chamber so that the water flowing through the flow path is connected to the water purification cart. The first feature is that the liquid is ejected through the ridge. In addition, the present invention provides a water faucet with a water purifier that has a branch in the flow path in which the chamber is formed. The flow path is formed into a branched shape, and a valve port is provided in each of the branch flow paths and the secondary flow path of the water purification cartridge. The faucet main body includes a valve body that selectively opens each valve port to the discharge side flow path. A further feature is that the device is incorporated into the device. Furthermore, in the present invention, the faucet body is a hot water mixed faucet, and a chamber is formed. The flow path is a hot water mixed water flow path, and the valve port of the secondary flow path of the water purification cartridge. When the water purification cartridge is blocked, a small amount of water from the secondary flow path of the water purification cartridge is constantly transferred to the discharge flow path. The device is characterized by having a communication portion for allowing a large amount of water to flow through the device.

[0008]

[Effect]

When the water tap is opened, the flowing water in the flow path enters the water purification cartridge and is filtered by the filter media. It is purified and impurities such as limescale, off-flavors, and red rust are removed before flowing into the discharge flow path. do. Here, the water purification cartridge is housed in a chamber that is integrally formed with the faucet body. , so even if the water pressure inside the chamber increases, the pressure inside the water purification cartridge remains the same. This prevents the case from being destroyed or deformed by this. The water purification cartridge is always immersed in the flow path of the main body of the faucet, and does not allow water to flow through the branch flow paths (original flow path). The water flows when water is discharged (discharge of water), and the water around the cartridge is No more stagnation. Furthermore, by passing a small amount of water, water can be replaced even more completely. It will be done.
