Abstract

A flow control device of a drink brewing device is disposed among a pump, a boiler, and a reflow pipe. When the brewing head is not releasing water, the pressure of cold water at a first end of the flow control device is lower than the pressure of hot brewing water at a third end, such that an adjustment element of the flow control device is pushed to block the first end and the brewing water circulates within the device. When the brewing head is releasing water, the pump begins to pump pressured cold water into the first end, which now has pressure higher than that at the third end, such that the adjustment element of the flow control device is pushed to block the third end and the pressured cold water can only flow through the second end into the boiler.

Description

Drinking device with waterway control

The present invention relates to a beverage brewing device, and more particularly to a beverage brewing device that utilizes a shuttle valve for waterway control.

Commercial beverage brewing devices generally use a mother-and-boiler as a heating system to heat cold water, which mainly includes a mother boiler, a sub-boiler, a water inlet unit, an outlet pipe, a cooking head, and a return pipe. The cold water is introduced into the mother boiler and the sub-boiler disposed in the mother boiler by the water inlet unit, the outlet pipe is connected to the sub-boiler and the cooking head, and the return pipe is connected between the cooking head and the sub-boiler. When brewing, the hot water in the sub-boiler flows out through the outlet pipe to the outlet of the cooking head to extract tea, coffee, etc. for beverage brewing. Prior art brewing devices typically require preheating of the cooking head using a hot-to-up, cold-down thermal cycle principle from the sub-boiler, and the condensed water is returned to the sub-boiler via a return pipe for reuse.

In the process of using the beverage brewing device, the water inlet unit will input cold water into the sub-boiler and indirectly through the hot water in the heating tank of the mother boiler (or additionally by a heater). After the mother boiler heats the water in the sub-boiler to a set temperature, the pressurized pump pushes the hot water in the sub-boiler through the outlet pipe to the steaming head, and the unused hot water is returned to the water pipe. Flow back into the sub-boiler. When there is no water, the pressurized hot water flows continuously between the sub-boiler, the water pipe and the cooking head in a constant temperature and constant pressure state.

However, in the prior art, the cold water supply of the pressurized pump and the hot water recovered through the return pipe are connected to the sub-boiler by a pure three-way valve, although the size of the conventional three-way valve may be three-way pressure. The pressure of high-temperature hot water that is strong water is greater than the cold water pressure called weak water.) The difference determines the flow direction of water, but when the pressurized pump pressurizes the cold water into the boiler, part of the cold water may be returned by the return pipe. Flowing to the cooking head causes the water temperature of the cooking head to gradually drop until it is unable to brew at a sufficient temperature, thereby affecting the endurance of the beverage brewing device.

In order to solve the above problems, the present invention provides a beverage brewing device with waterway control.

In an embodiment of the present invention, the water brewing device with a waterway control includes a boiler, a heating device, a waterway control device, a cooking head, and a pressurized pump. The boiler has a water outlet end and a water return end, and a brewing water in the boiler can be heated to a set temperature. The heating device is coupled to the boiler for heating the brewing water in the boiler to the set temperature. The waterway control device has a first end, a second end and a third end, and the water return end of the boiler is connected to the second end of the waterway control device. The cooking head is connected to the water outlet end of the boiler through an outlet pipe, and is connected to the third end of the waterway control device through a water return pipe, and the brewing water is discharged from the steaming head through the water outlet pipe. The pressurized pump is coupled to the first end of the waterway control device, and the pressurized pump is pressurized to provide a cold water from the waterway control device into the boiler.

In an embodiment of the present invention, in a state in which the pressurized pump is not pressurized to supply cold water, the brewing water in the boiler sequentially passes through the water outlet pipe, the cooking head, and the return water pipe, and the waterway The third end of the control device enters the waterway control device and is self-circulating by the second end of the waterway control device flowing back into the boiler.

In an embodiment of the present invention, wherein the cold water is pressurized to provide the cold water, the cold water enters the waterway control device by the first end of the waterway control device, and is controlled by the waterway control device The second end enters the boiler and is heated to the set temperature, and the brewing water in the boiler is pushed out to the cooking head through the outlet pipe.

The beverage brewing device 100 comprises a heating device 1, a boiler 2, an outlet pipe 3, a cooking head 4, a return pipe 5, a pressurized pump 6 and a waterway control device 7, as in the beverage brewing device 100. Other necessary components are not drawn, and will not be described here. After the boiler 2 is externally filled with water, a brewing water 8 in the boiler 2 is heated to a set temperature by the heating device 1 connected to the boiler 2. In other embodiments, the boiler 2 may also be disposed in a mother boiler (not shown), and the heating water of a certain amount of water is not fully filled in the mother boiler, and the heating water of the boiler 2 and the mother boiler is Direct contact is made such that the brewing water 8 in the boiler 2 is heated by the mother boiler to the set temperature.

The waterway control device 7 is disposed between the pressurized pump 6, the boiler 2, and the return pipe 5, and serves as a waterway control element that supplements the return of cold water and hot water. In the present creation, the waterway control device 7 is a three-way shuttle valve having a first end 71, a second end 72, and a third end 73. The boiler 2 has a water outlet end 21 and a water return end 22, and the outlet pipe 3 is connected between the water outlet end 21 and the cooking head 4. The heated brewing water 8 in the boiler 2 flows from the water outlet end 21 through the outlet pipe 3 to the cooking. Head 4. The return pipe 5 is connected to the cooking head 4 and the third end 73 of the waterway control device 7, and the first end 71 of the waterway control device 7 is connected to the pressurized pump 6, and the second end 72 is connected to the return end 22 of the boiler 2. . The brewing water 8 that has not been used in the cooking head 4 flows through the water return pipe 5 through the waterway control device 7, and flows back into the boiler 2.

The pressurized pump 6 is used to supply pressurized cold water, enters the boiler 2 via the waterway control device 7, to replenish the boiler 2, and also pressurizes the brewing water 8 in the boiler 2 to determine the beverage brewing device 100. The brewing water 7 is water pressure which is discharged from the cooking head 4.

Please refer to FIG. 2, which is a schematic diagram of the water flow state of the waterway control device in the creation beverage brewing device when the cooking head is not supplied with water. As shown in Fig. 2, in the state in which the cooking head 4 of the beverage brewing apparatus 100 of Fig. 1 is not supplied with water, that is, the pressurized pump 6 is not pressurized to supply cold water, in the beverage brewing apparatus 100. The brewing water 8 generates a self-circulation in the pipeline of the apparatus, as follows: For the three ports of the waterway control device 7, the first end 71 receives cold water from the pressurized pump 6, and the second end 72 will be The cold water from the first end 71 or the brewing water 8 returned from the third end 73 is supplied to the boiler 2, and the third end 73 is the brewing water 8 receiving the return pipe 5 (the temperature caused by the pipeline) The water temperature of the brewing water 8 of the return water pipe 5 is usually lower than the set temperature at which the brewing water 8 is heated. As previously mentioned, the waterway control device 7 may specifically be a three-way shuttle valve and includes an adjustment member 75. In a preferred embodiment, the adjustment member 75 is a ball that can be moved in a three-way shuttle. The valve is pushed to selectively plug the first end 71 or the third end 73 of the waterway control device 7. In Fig. 2, since the pressurizing pump 6 does not act, the cold water pressure at the first end 71 will be lower than the pressure of the high-temperature brewing water 8 at the third end 73, thereby bringing the regulating member 75 to the first The end 71 pushes and plugs the first end 71 of the waterway control device 7, at which time the self-circulation (refer to Fig. 1) of the brewing water 8 in the pipeline of the device due to the difference in temperature is sequentially followed by the water outlet end of the boiler 2. 21 enters the waterway control device 7 via the outlet pipe 3, the retort 4, the return pipe 5, and the third end 73 of the waterway control device 7, and flows back into the boiler 2 by the second end 72 (as indicated by the thick arrow in Fig. 2).

Please refer to FIG. 3, which is a schematic diagram of the water flow state of the waterway control device in the creation beverage brewing device when the steaming head is supplied with water. As shown in Fig. 3, in the state in which the retort 4 of the beverage brewing device 100 of Fig. 1 is supplied with water (for example, pressing the retort 4 of the beverage brewing device 100 or a water supply button, a water supply switch, etc. in an adjacent position) Then, the pressurized pump 6 can be controlled to start to operate to supply cold water, and since the pressurized pump 6 is pressurized to provide cold water, the cold water pressure at the first end 71 is greater than the high temperature brewing water at the third end 73. The pressure of 8 pushes the adjusting member 75 toward the third end 73 to plug the third end 73 of the waterway control device 7, and the cold water supplied by the pressurizing pump 6 is pressurized by the first end 71 of the waterway control device 7. The waterway control device 7 is entered into the boiler 2 by the second end 72 (such as the thick arrow in Fig. 3) and heated by the heating device 1 to the set temperature, while the brewing water 8 in the boiler 2 (and the outlet pipe 3) is also The pushed net cooking head 4 is released. Since the adjusting member 75 of the waterway control device 7 plugs the third end 73 connected to the return pipe 5, in the state where the cooking head 4 is supplied with water, the cold water supplied by the pressurizing pump 6 can be effectively prevented from being supplied from the third end. The inflow of the return water pipe 5 causes the water temperature of the cooking head 4 to drop, which affects the endurance of the beverage brewing device 100.

The beverage brewing device of the present invention is provided with a waterway control device between the pressurized pump, the boiler and the return water pipe. When the steaming head is not supplied with water, the cold water pressure at the first end of the waterway control device is lower than the high temperature at the third end. The pressure of the brewing water causes the regulating element of the waterway control device to plug the first end, and the brewing water creates a self-circulation in the conduit of the device. When the cooking head feeds water, the pressurized pump pressurizes to provide cold water so that the cold water pressure at the first end is greater than the high temperature brewing water pressure at the third end, thereby causing the regulating element to plug the third end and pressurizing The cold water enters the boiler only from the second end, thereby effectively preventing the cold water supplied by the pressurized pump from flowing into the return water pipe from the third end, thereby causing the water temperature of the cooking head to decrease, which affects the endurance of the beverage brewing device.
