Heating and refrigerating water device

Abstract

A heating and refrigerating water device includes a thermos container for receiving a predetermined amount of water therein, a temperature control arrangement comprising a heating unit and a semi-conductor refrigerating unit, and a control circuitry, which is adapted for electrically connecting with a power source, electrically connected with the temperature control arrangement, wherein the control circuitry is controlled to selectively activate the heating unit and the semi-conductor refrigerating unit for respectively heating up and refrigerating the water within the thermos container.

Description

BACKGROUND OF THE PRESENT INVENTION [0001] 1. Field of Invention [0002] The present invention relates to a water dispensing system, and more particularly to a heating and refrigerating water device, wherein the water is heated and refrigerated within a single thermos container so as to simplify the structural design of the water device. [0003] 2. Description of Related Arts [0004] Electric water dispensers are considered as one of the major home appliances for applying hot and cold water. Generally speaking, there are two types of electric water dispenser which are a water boiler and a water dispenser. [0005] A conventional water boiler generally comprises an outer casing, an inner thermos container disposed in the outer casing, and a boiling device adapted to boil the water in the thermos container so as to keep the water at a predetermined temperature therein. Since the boiling device can boil the water at a relatively high temperature, such as 100° C., to kill the bacterial in th...

AI Technical Summary

Benefits of technology

"The present invention provides a heating and refrigerating water device that has the following technical effects: \n1. The water is heated or refrigerated within a single thermos container, simplifying the structural design of the water device. \n2. The thermos container can be easily removed for cleaning, minimizing water pollution. \n3. The device can be incorporated with conventional water dispensing systems without altering their structure, reducing manufacturing costs. \n4. Both the heating unit and the refrigerating unit are controlled by a single control circuitry, simplifying the electrical configuration of the device. \n5. No expensive or mechanical structure is required to employ the invention, making it an economic and efficient solution."

Problems solved by technology

In other words, the water will be polluted once the impure layer is formed on the thermos container.

However, the water boiler can only provide hot water.

However, the water dispenser requires two individual water containers to boil and refrigerate the water respectively such that the structural design of the water dispenser is complicated so as to highly increase the manufacturing cost of the water dispenser.

In addition, each of the first and second water containers is a sealed container and is permanently installed into the water dispenser such that the user is not able to remove the water containers from the water dispenser in order to clean the water containers.
