Description

Faucet for cold and warm water having an automatic temperature control function}

The present invention relates to a faucet for cold and hot water, and more particularly, to a cold and hot water faucet having a structure for automatically adjusting the mixing ratio of cold water and hot water so that the discharge water temperature becomes a temperature set by a user within a short time. will be.

Conventional cold and hot water mixing valve is configured to mix the cold water and hot water flowing through the cold water pipe and hot water pipe at a rate set by the user in advance, and discharged at a temperature set by the user. The cold and hot water mixing valve is to control the opening and closing amount of the cold water valve and the hot water valve connected to the cold water pipe for introducing cold water, hot water pipe for introducing hot water, respectively, by the handle or lever for temperature control.

However, in the conventional cold and hot water mixing valve, the user manually adjusts the temperature adjusting handle or lever to set the temperature of the discharged water discharged from the tap to the desired temperature. After that, there was a problem in that the water consumption of the wastewater was unnecessarily consumed by readjusting the handle or the lever until the temperature of the discharged water reached the desired temperature.

Examples of automatic water conduction to automatically adjust the temperature of the water in order to solve the above problems include "automatic water conduction" of Patent Document 1 and "automatic water supply and the valve assembly configured therein" of Patent Document 2.

Patent Document 1: Patent Publication No. 1993-0005335 (Notice date 1993. 6. 17.) Patent Document 2: Patent Publication No. 195-0011801 (Notification date 1995. 10. 10.) The automatic water conduction disclosed in Patent Document 1 includes a mixing chamber, a cold / hot water mixing tube in which a cold / hot water inlet is formed, and a plurality of cold / hot water outlets that can communicate with the mixing chamber are formed, and a bimetal in the mixing chamber. A temperature sensor, a cold / hot water mixing valve having a flow opening / closing tube which is installed to slide in the cold / hot water mixing pipe so as to selectively open / close the cold / hot water outlet in response to the operation of the bimetal, and is operatively engaged by the bimetal. It is composed. However, the cold and hot water mixing valve of the automatic faucet disclosed in Patent Document 1 is connected to the outer end of the spiral (or helical) bimetallic flow opening and closing pipe slidingly sliding in the left and right direction in the hot and cold water mixing pipe, There was a problem that the temperature control was not large and fine. That is, the inner (center) end of the spiral bimetal disclosed in Patent Document 1 is fixed to the central axis for temperature control, and the outer end moves the flow opening / closing tube in left and right directions through the opening / closing tube actuator to cool the cold water outlet and hot water. It was almost impossible to adjust the temperature manually because the outlet was opened and closed at the same time. For example, if the temperature control knob is rotated only about 7 ° and the central axis for temperature control is rotated about 7 °, the tip of the bimetal is rotated by 7 ° so that either the cold water outlet or the hot water outlet is completely closed and the other is fully open. The phenomenon occurred that the temperature control was almost impossible. On the other hand, the automatic water tap disclosed in Patent Document 2 is provided with a mixing valve for opening the passage between the inner and outer cylinders formed with the cold water passage and the hot water passage by the helical bimetal drive. However, the inner (center) end of the spiral bimetal disclosed in Patent Document 2 is fixed to the central axis for temperature control, and the outer end is fixed to the outer cylinder of the mixing valve with a pin, and the outer cylinder is rotated by driving the bimetal. Since it is configured to open and close the cold water passage and the hot water passage, it was almost impossible to manually adjust the temperature. For example, if the knob for temperature control is rotated only about 10 °, the central axis for temperature control is also rotated about 10 ° and the tip of the bimetal is rotated 10 ° so that either the cold or hot water path of the mixing valve is completely closed and fully open.

[Setting of Drainage Temperature of Cold and Hot Water Faucet (1)]

When the user rotates the temperature controller 12 to set the temperature of the water discharged from the head lever 15 of the faucet 1, the rotary gear 35 axially coupled to the temperature setting rotation shaft 16 is rotated. In addition, the reduction gear 36 larger than the diameter of the rotation gear 35 is coupled between the rotary gear 35 and the teeth formed around the inner circumferential surface of the ring gear 34. At this time, if the reduction ratio of the rotary gear 35 and the reduction gear 36 is 5: 1, and the reduction ratio of the reduction gear 36 and the ring gear 34 is 3: 1, the total reduction ratio is 15: 1. When the temperature controller 12 is rotated 15 °, the ring gear 34 is rotated by 1 °.

When the ring gear 34 is rotated about the temperature control rotation shaft 16 by the reduction gear 36, the helical bimetal 32 having an external end connected to the pin hole 38 formed at the edge thereof is connected to the pin 39.
