Abstract

A beer maker may include a fermentation vessel accommodated in a space and having a beer brewing space, a main channel communicating with the beer brewing space, a sub-channel communicating with the beer brewing space, a gas pump connected to the sub-channel to pump gas to the sub-channel, and a gas valve at the sub-channel. Ingredients for brewing beer are supplied to the beer brewing space through the main channel, and gas is supplied to the beer brewing space through the sub-channel, so that beer can be simply brewed while minimizing a user from opening the lid.

First claim

What is claimed is:

1. A beer maker comprising:
a body including a housing having a space formed therein;
a fermentation container provided at the space, the fermentation container comprising a flexible container having a beer brewing space;
a lid connected to the housing to close the space;
a main channel that communicates with the beer brewing space, the main channel arranged to pass through the lid to guide ingredients for brewing beer to the beer brewing space;
a temperature regulating device provided to the body or the lid, the temperature regulating device to regulate a temperature of the fermentation container;
a sub-channel arranged to guide gas outside of the flexible container;
a gas pump, at the sub-channel, to pump gas, wherein the gas guided to the outside of the flexible container presses the flexible container in a state in which the lid is not opened, and beer in the beer brewing space is discharged to the main channel;
an ingredient supplying device connected to the main channel;
a beer extracting device coupled to the main channel by a connection part;
a main valve between the body and the connection part at the main channel; and
a controller configured to selectively open and close the main valve;
wherein the controller is configured to open the main valve so that the ingredients from the ingredient supplying device are injected into the beer brewing space through the main channel,
wherein the fermentation container is withdrawable from the space to outside of the body in a state in which the lid is opened.

2. The beer maker of claim 1 , further comprising a filter, at the sub-channel, to allow gas to pass.

3. The beer maker of claim 1 , further comprising a gas valve at the sub-channel,
wherein the sub-channel includes a gas injection channel that couples the gas pump to the gas valve.

4. The beer maker of claim 1 , wherein the sub-channel includes an outer sub-channel, wherein at least a portion of the outer sub-channel is outside of the body.

5. The beer maker of claim 4 , comprising a pressure sensor coupled to the outer sub-channel.

6. The beer maker of claim 4 , comprising a gas discharge valve to discharge gas from the outer sub-channel to outside of the body.

7. The beer maker of claim 6 , wherein the gas discharge valve is coupled to the outer sub-channel by a gas discharge valve connection channel.

8. The beer maker of claim 4 , wherein the sub-channel includes:
a body sub-channel coupled to the outer sub-channel, the body sub-channel being at the housing or the lid; and
a fermentation container sub-channel at the fermentation container, the fermentation container sub-channel for communicating with the beer brewing space and the body sub-channel.

9. The beer maker of claim 1 , wherein the fermentation container includes:
an outer vessel in the space, wherein the flexible container is provided in the outer vessel.

10. The beer maker of claim 9 , wherein the sub-channel extends between the outer vessel and the flexible container.

11. The beer maker of claim 1 , wherein the gas pump is provided outside of the body.

12. The beer maker of claim 10 , wherein a pressurization channel is coupled to the sub-channel, and
wherein the pressurization channel includes:
a fermentation vessel pressurization channel at the outer vessel, the fermentation vessel pressurization channel for communicating between the outer vessel and the flexible container;
a body pressurization channel at the body, the body pressurization channel for communicating with the fermentation vessel pressurization channel; and
an outer pressurization channel to couple the body pressurization channel to the sub-channel.
