DETAILED DESCRIPTION OF THE INVENTION

A beverage device of a first embodiment according to the preferred teachings of the present invention is shown in FIG. 1 and generally includes a body 1, two temperature conducting devices 2, and two tanks 3. Each temperature conducting device 2 is received in the body 1 and maintains one of the tanks 3 at a predetermined temperature. Each tank 3 can be detached from the body 1. It can be appreciated that the beverage device can include only one or more than two tanks 3 and a corresponding number of temperature conducting devices 2.

The body 1 includes a housing 11 receiving a temperature control unit 12. The temperature control unit 12 can be a cooling device, a heating device, or a device capable of heating and cooling. A temperature of a beverage received in each tank 3 connected to one of the temperature conducting devices 2 can be lowered or raised to a predetermined temperature. In this embodiment, the temperature control unit 12 is a cooling device and includes a compressor 121, a condenser 122, a conduit unit 123, and a temperature controlling member 124. The compressor 121 and the condenser 122 supply a low-temperature coolant that flows through the conduit unit 123 and passes through each temperature conducting device 2. The temperature controlling member 124 detects whether each temperature conducting device 2 has reached the predetermined temperature so as to control operation of the temperature conducting device 2. In this embodiment, the temperature controlling member 124 is mounted at an end of the conduit unit 123 in front of the compressor 121.

With reference to FIGS. 1, 2a and 2b, each temperature conducting device 2 is received in one of two compartments 16 of the housing 11 of the body 1. Each compartment 16 has an opening 13 in an upper side of the housing 11 to expose and to allow removal of the temperature conducting device 2 received in the compartment. The housing 11 further includes two slots 14 each extending from a front side of the housing 11 though a periphery of one of the compartments 16. Each temperature conducting device 2 is easy to manufacture. Each temperature conducting device 2 comprises a temperature conducting body 21 and a shade 22 both of which are made of a material having good heat conducting efficiency. An outer periphery of the temperature conducting body 21 is preferably in intimate contact with an inner periphery of the shade 22. Most preferably, the outer periphery of the temperature conducting body 21 and the inner periphery of the shade 22 are conic as shown in FIG. 2b. The temperature conducting body 21 is processed to form a continuous passageway 211 for the coolant. The passageway 211 is preferably helical and formed in the outer periphery of the temperature conducting body 21. A first end of the passageway 211 is a first end, and the passageway 211 extends through an interior of the temperature conducting body 21 with a second end of the passageway 211 beyond an end face of the temperature conducting body 21. A first connecting portion 212 is provided at the first end of the passageway 211, and a second connecting portion 213 is provided at the second end of the passageway 211. After the temperature conducting body 21 is received in a receiving space 221 of the shade 22, the opening of the shade 22 can be sealed by welding or by armored spacers and bolts. Since the outer periphery of the temperature conducting body 21 is in intimate contact with the inner periphery of the shade 22, the passageway 211 formed in the outer periphery of the temperature conducting body 21 forms a channel allowing the coolant to flow therethrough. One of the first and second connecting portions 212 and 213 is the input end, and the other of the first and second connecting portions 212 and 213 is the output end. It can be appreciated that even though the outer periphery of the temperature conducting body 21 is not in intimate contact with the inner periphery of the shade 22, the whole temperature conducting device 2 can still be controlled at a predetermined temperature, although the coolant may leak to from one section to another section of the helical passageway 211.

With reference to FIGS. 1 and 3, each tank 3 receives a beverage and is placed in one of the compartments of the housing 11 and in contact with one of the temperature conducting devices 2 to receive the temperature of the temperature conducting device 2, so that the temperature of the tank 3 can be controlled at the predetermined temperature. To provide the beverage in the tank 3 with the best heat conduction effect, each tank 3 includes an inner layer 31, an outer layer 32, and a cover 36. The inner layer 31 is made of a material having good heat conducting efficiency. The inner layer 31 includes a contact portion 35 and a receiving portion 33 having an opening. The receiving portion 33 receives the beverage. A beverage faucet 34 can be provided to each tank 3 to allow controllable dispensation of the beverage. When each tank 3 is received in one of the compartments 16 of the housing 11 placed on and in contact with one of the temperature conducting devices 2, the beverage faucet 34 of the tank 3 extends beyond the housing 11 via one of the slots 14 to allow easy operation. Each tank 3 further includes a recessed bottom 30 having a peripheral wall forming a contact portion 35 in a conical shape corresponding to the shade 22. Thus, when the recessed bottom 30 of the tank 3 is placed on the shade 22, the contact portion 35 can be in intimate contact with the shade 22 to provide excellent heat conducting effect for the beverage received in the tank 3. The outer layer 32 is made of heat insulating material and envelopes an outer peripheral wall of the inner layer 31 except the contact portion 35, providing excellent temperature-maintaining effect. Each cover 36 can be removably mounted to the open end of one of the tanks 3, allowing easy supply of beverage into the tank 3. In this embodiment, the cover 36 has an outer thread threadedly engaged with a threaded inner periphery of the open end of the tank 3. Furthermore, each tank 3 can include a grip 37 in the form of a handle or formed on a top face of the cover 36 to allow easy removal of the tank 3 from the housing 11 by gripping the grip 37.

With reference to FIG. 4, the contact portion 35 of each tank 3 received in one of the compartments 16 of the housing 11 and placed on one of the temperature conducting devices 2 is in intimate contact with the shade 22 of the temperature conducting device 2. Thus, when the compressor 121 and the condenser 122 of the temperature control unit 12 are operating, the coolant flows in the conduit unit 123 to quickly lower the temperature conducting body 21 of each temperature conducting device 2 to the predetermined temperature via the shade 22, so that the beverage in each tank 3 can be at the desired temperature. Furthermore, the temperature controlling member 124 senses the temperature of the coolant flowing back from the temperature conducting device 2 to decide whether the temperature control unit 12 should be activated to raise or lower the temperature. Thus, a user can easily acquire the beverage at the desired temperature by the beverage faucet 34 on each tank 3.

With reference to FIG. 5, when the beverage of the tank 3 placed on the temperature conducting device 2 reaches the predetermined temperature, the tank 3 can be removed from the temperature conducting device 2 and placed on a movable seat 4 with the recessed bottom 30 engaged on an insertion portion 41 of the movable seat 4 so that the tank 3 can be reliably supported on the movable seat 4. Then, a new tank 3 receiving beverage therein can be placed on the temperature conducting device 2 to lower the beverage to the predetermined temperature.

A temperature maintaining member 42 can be placed between the insertion portion 41 of the movable seat 4 and the recessed bottom 30 of the tank 3 supported on the movable seat 4, keeping the beverage in the tank 3 at the predetermined temperature for a longer period of time. As an example, the temperature maintaining member 42 can be initially stored at a predetermined temperature and then placed into a space between the insertion portion 41 of the movable seat 4 and the recessed bottom 30 of the tank 3 removed from the temperature conducting device 2 of the body 1. Thus, the beverage in the tank 3 can be kept at the predetermined temperature for a longer period of time due to sealing of the movable seat 4.

FIGS. 6 and 7 show a second embodiment according to the preferred teachings of the present invention including the body 1, the temperature conducting devices 2 and the tanks 3 the same as those in the first embodiment. Particularly, a bottle seat 5 is mounted in the opening of each tank 3 and includes a guiding hole 51. A check valve 52 mounted to a beverage-containing bottle 50 can be inserted into the guiding hole 51 of the bottle seat 5. With reference to FIG. 7, after the check valve 52 is inserted in the guiding hole 51 of the bottle seat 5, the check valve 52 is open, and the beverage in the beverage-containing bottle 50 can be automatically supplied into the tank 3.

The beverage device according to the preferred teachings of the present invention can keep the beverage received therein at the predetermined temperature. Furthermore, the tanks 3 can be easily detached from the beverage device according to the preferred teachings of the present invention for cleaning purposes. Furthermore, the tanks 3 removed from the beverage device can be kept at the predetermined temperature for a longer period of time by using the temperature maintaining member 42 according to the teachings of the present invention. Further, the tanks 3 according to the teachings of the present invention can be utilized with or without the beverage device. Further, the temperature control unit 12 according to the teachings of the present invention is easy to manufacture. Further, beverage-containing bottles 50 can be mounted to the beverage device for automatically supplying the beverage into the tanks 3.

Thus since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive.
