Address for Service A.P.T. Patent and Trade Mark Attorneys PO Box 222 Mitcham, S.A. 5062 The invention is described in the following statement: THERMOSTATIC WATER SUPPLY DEVICE FREE FROM HAND TOUCH BACKGROUND OF THE INVENTION a) Field of the Invention The present invention relates to piping and a valve control technology of a 5 water supply system, and more particularly to a thermostatic water supply device free from hand touch, by which an outlet temperature can be adjusted and there is no need to control discharge of a water faucet by hands. b) Description of the Prior Art Normally, when using a water faucet to get water, a water source will 10 directly provide water to the water faucet and by turning on or off the water faucet, a discharge condition (e.g., a yield and a breakthrough time, etc.) of the water faucet can be controlled. Therefore, under a condition that water is supplied normally by the water source, once a user turns on the water faucet, water will flow out of the water faucet continuously, allowing water to be used 15 successfully. In other words, the user needs to turn the water faucet by hands that the discharge condition of the water faucet can be controlled. Yet, as there are a lot of users in an ordinary public place, if the water faucet is not cleaned regularly, then dirt will be easily accumulated and germs can be easily 20 spreading out. 2 Accordingly, in a hospital or a restaurant kitchen, a water supply device, discharge of the water faucet of which is controlled by stepping, will be used frequently to prevent the water faucet from being touched by both hands that germs or dirt on the hands will be remained on the water faucet or a related 5 water supply switch to form a path for spreading out the germs. Nevertheless, most conventional water supply devices free from hand touch are only equipped with the function of controlling the discharge of the water faucet and are not yet provided with a function of adjusting the outlet temperature. Therefore, it is not very convenient to use these conventional 10 water supply devices and will relatively reduce applicability of the water supply devices free from hand touch. SUMMARY OF THE INVENTION Accordingly, the primary object of the present invention is to provide a thermostatic water supply device free from hand touch, by which the outlet 15 temperature can be adjusted and there is no need to control the discharge of the water faucet by hands. To achieve the aforementioned object, the thermostatic water supply device free from hand touch, according to the present invention, includes primarily a water faucet, a water control assembly and a water control valve, 20 wherein the water control valve is provided with a cold water inlet pipe, a hot 3 water inlet pipe and a first outlet pipe; whereas, the water control assembly is connected with the first outlet pipe and is connected to the water faucet through a second outlet pipe. The water control valve is used primarily to control yields of cold and hot 5 water entering into the first outlet pipe, achieving an object of adjusting the water temperature. In addition, through the water control assembly, the user is able to control continuity of a passage between the first outlet pipe and the second outlet pipe, thereby controlling the discharge of the water faucet. In particular, using an extension function of the second outlet pipe, the 10 water control assembly can be fitted at a location where the user can step by a foot or other part of body conveniently, without touching by both hands to control the discharge of the water faucet. Therefore, germs on the hands will not be remained on the water supply device, which removes a path for spreading out the germs. 15 To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
