Description
TITLE: AUTOMATIC DRIP COFFEE MAKER
BACKGROUND OF TFIE INVENTION
(a) Field of the Invention The present invention is related to an automatic drip coffee maker, and s more particularly, to one provided with a bowl in a chamber to contain coffee, and a thermostat and a heating tube to continuorasly keep the coffee hot for preventing pollution, and easy access for a drink with various types of container.
(b) Description of the Prior Art ~o Whereas there is the great population of coffee-drinker, a coffee maker is very popular. As illustrated in Fig. 6 of the accompanying drawings, an automatic drip coffee maker A contains a reservoir Al, a heater A2 to heat the water in the reservoir A1, a basket A3 containing ground coffee beans, a pipe A4 for the hot water to enter into the basket A3, a. valve AS disposed at the m bottom of the basket A3, and a dedicated coffee pot A6 placed below the basket A3 and 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 A6 hot.
To fetch for a cup of coffee, the coffee pot A~ must be removed away ao from where below the valve AS of the basket A3 to 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 A6 is not necessarily able to hold against and open up the valve A5; that the coffee is vulnerable to be contaminated due to that coffee pat A~ is exposed out of the as coffee maker A without any screening structure; and that the coffee gets cool easily due to the insufficient warning 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 he used to fetch for the coffee, since there l o is no need for the dedicated coffee pot to permit an easy and convenient access to the coffee.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As illustrated in Figs. 1 and 2, an automatic drip coffee maker 1 of the present invention essentially comprises a reservoir 1I, a basket 13, and a chamber 14. The reservoir 11 is disposed on the back of the coffee maker 1.
s A heater 12 is provided to heat up the water in the reservoir 11. The hot water enters into the basket 33 through a delivery pipe 121. Ground coffee beans are placed in the basket 13 and an opening I31 is disposed at the bottom of the basket 13. The chamber 14 is provided at where below the opening 131. A
mobile door 141 is provided to the outer side of the chamber 14. A thermostat l 0 15 and a heating pipe I 51 are disposed at the bottom of the chamber 14. A
bowl 16 is placed in the chamber 14 and an outlet 161 is disposed at the bottom of the bowl 16. The outlet 16I is subject to the control by a control device 17.
The control device 17 is made in a rod Shape wW a valve block 171 disposed at the bottom of the control device 17. A spring 172 is inserted onto the valve block 171, and the spring 172 is compressed by the control device 17 to move the valve block 171, thus to open up the outlet 16I.
To make coffee, as illustrated in Fig. 3, fill up the reservoir 11 with water, place the proper amount of ground coffee beans into the basket 13, place the bowl 16 into the chamber 14, the outlet 161 is plugged by the valve block 171 a o of the control device 17 with the elasticity exercised by the spring 172, thus to close up the mobile door 141. Water in the reservoir 11 is heated up by the heater 12 and the hot water is then guided through the delivery pipe 121 into the basket 13 to filter through the ground coffee beans contained in the basket 13 for the coffee drips to fall into the bowl 16 in the chamber 14 through the 25 opening 131. The coffee in the bowl I6 is kept hot by means of the thermostat 15 and the heating pipe 151. To fetch for a cup of coffee as illustrated in Fig.
