Automatic drip coffee maker

An automatic drip coffee maker includes a reservoir, a basket, and a chamber disposed at where below an opening of the basket. A thermostat and a heating tube are provided at the bottom of the chamber. A bowl is placed into the chamber to receive coffee drips delivered through the opening of the basket. The coffee in the bowl is continuously kept hot due to the thermostat and the heating tube without being contaminated. A control device is provided in the bowl to control the delivery of the coffee through an outlet to be poured into any type of coffee cup.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention is related to an automatic drip coffee maker, and more particularly, to one provided with a bowl in a chamber to contain coffee, and a thermostat and a heating tube to continuously keep the coffee hot for preventing pollution, and easy access for a drink with various types of container.

(b) Description of the Prior Art

Whereas there is the great population of coffee-drinker, a coffee maker is very popular. As illustrated inFIG. 6of the accompanying drawings, an automatic drip coffee maker A contains a reservoir A1, a heater A2to heat the water in the reservoir A1, a basket A3containing ground coffee beans, a pipe A4for the hot water to enter into the basket A3, a valve A5disposed at the bottom of the basket A3, and a dedicated coffee pot A6placed below the basket A3and holding with its top against and open up the valve A5, coffee drips automatically drop into the coffee pot A6, and a warming plate disposed at the bottom of the coffee pot A to keep coffee in the coffee pot A6hot.

To fetch for a cup of coffee, the coffee pot A6must be removed away from where below the valve A5of the basket A3to pour the coffee into a cup. However, the prior art of the coffee maker is found with several shortcomings including that any container other than the dedicated coffee pot A6is not necessarily able to hold against and open up the valve A5; that the coffee is vulnerable to be contaminated due to that coffee pot A6is exposed out of the coffee maker A without any screening structure; and that the coffee gets cool easily due to the insufficient warming results of the warming panel.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a coffee maker that does not require a dedicated coffee pot, allows easy access for having a cup of coffee, prevents coffee from being contaminated, and assures of a sufficient warming effect for the coffee. To achieve the purpose, a chamber inserted with a bowl is disposed at where below an opening of the basket, and a thermostat and a heating tube are provided at the bottom of the chamber, an outlet is disposed at the bottom of the bowl adapted with a control device.

Accordingly, the present invention has the following advantages:1. Any type of coffee cup can be used to fetch for the coffee, since there is no need for the dedicated coffee pot to permit an easy and convenient access to the coffee.2. A thermostat and a heating pipe are provided at the bottom of the chamber to ensure of keeping the coffee hot in the bowl.3. A mobile door is provided to the outer side of the chamber to prevent the coffee from being contaminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As illustrated inFIGS. 1 and 2, an automatic drip coffee maker1of the present invention essentially comprises a reservoir11, a basket13, and a chamber14. The reservoir11is disposed on the back of the coffee maker1. A heater12is provided to heat up the water in the reservoir11. The hot water enters into the basket13through a delivery pipe121. Ground coffee beans are placed in the basket13and an opening131is disposed at the bottom of the basket13. The chamber14is provided at where below the opening131. A mobile door141is provided to the outer side of the chamber14. A thermostat15and a heating pipe151are disposed at the bottom of the chamber14. A bowl16is placed in the chamber14and an outlet161is disposed at the bottom of the bowl16. The outlet161is subject to the control by a control device17. The control device17is made in a rod shape with a valve block171disposed at the bottom of the control device17. A spring172is inserted onto the valve block171, and the spring172is compressed by the control device17to move the valve block171, thus to open up the outlet161.

To make coffee, as illustrated inFIG. 3, fill up the reservoir11with water, place the proper amount of ground coffee beans into the basket13, place the bowl16into the chamber14, the outlet161is plugged by the valve block171of the control device17with the elasticity exercised by the spring172, thus to close up the mobile door141. Water in the reservoir11is heated up by the heater12and the hot water is then guided through the delivery pipe121into the basket13to filter through the ground coffee beans contained in the basket13for the coffee drips to fall into the bowl16in the chamber14through the opening131. The coffee in the bowl16is kept hot by means of the thermostat15and the heating pipe151. To fetch for a cup of coffee as illustrated inFIG. 4, just place any coffee cup B under the outlet161and press the control device17for the spring172to move the valve block171away from the outlet161for delivering the coffee into the coffee cup B as illustrated inFIG. 5
