Description

Technical Field

[0001] The utility model relates to a multifunctional direct-cooling constant-temperature high-pressure gas wine dispenser, belonging to the field of wine dispensers. Background Art

[0002] Existing barrel beer barrels (with fresh beer or draft beer inside) are mainly made of stainless steel (reusable) and plastic resin barrels (disposable), etc. They are all made by injecting edible carbon dioxide or clean compressed air at a pressure of 0.2MPa-0.31MPa into the beer barrel, and then press the beer in the beer barrel into the draft beer machine for cooling;

[0003] The source of carbon dioxide gas is from a gas cylinder with a high-pressure container of more than 5MPa, which is reduced to 0.2-0.31MPa through a pressure reducing valve and then injected into the beer keg. Because it is a high-pressure container and uses a pressure reducing valve, high-pressure gas can directly enter the beer keg due to operational errors or poor maintenance of the beer keg, causing the beer keg to rupture or even explode, resulting in personal injury accidents almost every year.

[0004] The structure uses clean compressed air as the air source. Although the air pressure is controlled between 0.2-0.31Mpa and there is no safety issue, the oxygen in the air will deteriorate the taste of the beer due to the direct contact between the air and the beer, and the shelf life is also shorter than that of carbon dioxide.

[0005] The Chinese utility model with application number CN2010.82033310.67.3 provides an air squeezed interlayer beer preservation barrel, an air pump, the air pump is connected to an air intake valve through an air pump hose, and the air intake valve is fixed on the outer shell of the beer barrel. The utility model uses a low-pressure air pump to inject gas, and the pressure of the injected gas does not exceed 0.4MPa. The stainless steel shell or plastic resin shell circulating in the market has an operating pressure within 0.1MPa, which effectively solves the safety hazards of high-pressure gas containers and pipelines, eliminates oxidation caused by foreign gas or deterioration of taste and quality caused by impurities, and also improves the shelf life.

[0006] However, when the equipment is in use, the air pump needs to be started every time it works, which will reduce the service life of the air pump; and the pressure is not very high when the air pump just starts working, and many times it is necessary to wait for three to five seconds before the gas can be pumped into the wine barrel. Utility Model Content

[0007] The purpose of the utility model is to provide a multifunctional direct-cooling constant-temperature high-pressure gas wine dispenser, which can effectively solve the above-mentioned problems.

[0008] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0009] It includes an air compressor, which is connected to an air tank via a connecting pipe, and the air tank is connected to a wine barrel via a hose; a pressure detection gauge is provided on the air tank, and a control chip and an automatic start-stop switch electrically connected to the control chip are provided on the air compressor, and the pressure detection gauge is electrically connected to the control chip.

[0010] Furthermore: a solenoid valve is provided at the connection between the gas storage tank and the hose, and a pressure reducing valve is also provided on the hose.

[0011] Further: the wine barrel is an inner membrane barrier barrel.

[0012] Further: it also includes a direct cooling freezer, the wine barrel is arranged inside the direct cooling freezer, and a wine outlet pipe is arranged at the upper end of the wine barrel.

[0013] Further: the cabinet door of the direct cooling freezer is hinged at the upper end of the cabinet body.

[0014] The beneficial effects are:

[0015] The high-pressure air generated by the air compressor of the device will first be added to the gas tank. In the process of the gas rushing into the gas tank, the pressure inside the gas tank gradually increases; after it increases to a pressure value of 0.8MPa, the pressure detection gauge detects the preset pressure value and feeds it back to the control chip, and the control chip controls the automatic start-stop switch to turn off the air compressor; and when the drinker receives the wine, the high-pressure gas will instantly enter the hose, flow through the pressure reducing valve to reduce the air pressure of 0.8MPa to the range of 0.3MPa-0.1MPa below 0.3MPa, and then enter the wine barrel, squeezing the inner membrane of the wine barrel to allow the wine to be discharged.

[0016] This arrangement can avoid the problem that the air pressure is not high when the air compressor starts, causing the drinker to wait too long;

[0017] At the same time, if the drinker does not drink much, the 0.8MPa air pressure in the gas tank is sufficient to attack the wine barrel to output a sufficient amount of wine. At this time, there is no need to turn on the air compressor, so the number of times the air compressor is started can be reduced and the service life of the air compressor can be extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] For ease of explanation, the present invention is described in detail by the following specific implementations and drawings.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] See also Figure 1 This is an embodiment of the utility model multifunctional direct cooling constant temperature high pressure gas wine dispenser.

[0024] The wine barrel 5 of the device is an inner membrane interlayer wine barrel, and the specific reference may be made to the application number "CN2010.82033310.67.3 Chinese utility model provides an air squeeze interlayer beer preservation barrel"; this type of beer barrel is commonly used on the market;

[0025] This type of wine barrel 5 has an inner membrane inside, and beer will be added to the inner membrane. When the beer needs to be extracted from the wine outlet pipe 10, it is only necessary to pass gas between the inner membrane and the beer barrel. After the gas is passed in, the inner membrane will be compressed, the pressure on the inner membrane will decrease, and the wine in the inner membrane will be squeezed out, so that the beer can be extracted.

[0026] Therefore, the wine barrel 5 needs to be equipped with an air compressor 1, and the air compressor 1 provides gas to squeeze the inner membrane in the wine barrel 5.

[0027] The device is an integrated beer dispenser. The function of such beer dispensers on the market is to be placed in restaurants. Drinkers only need to turn the tap or press the switch, and beer will come out of the beer dispenser. Therefore, drinkers will frequently use the device. In the prior art, an air pump is directly connected to the wine barrel 5 through a hose 4. When the drinker uses it, the air pump needs to work every time it is started to generate high-pressure gas to flow to the wine barrel 5. Such frequent starts will reduce the service life of the air pump.

[0028] At the same time, when the air pump is first started, the air pressure does not rise instantly, so it takes three to five seconds for the wine to be delivered, which increases the time it takes for the drinker to receive the wine.

[0029] Therefore, in order to solve the above problems, the present device is also equipped with an air storage tank 3 between the air compressor 1 and the wine barrel 5, and a pressure detection gauge 6 is arranged on the air storage tank 3, and a control chip and an automatic start-stop switch electrically connected to the control chip are arranged on the air compressor 1, and the pressure detection gauge 6 is electrically connected to the control chip.

[0030] In this arrangement, the high-pressure air generated by the air compressor 1 will first be added to the gas storage tank 3 through the connecting pipe 2. In the process of the gas rushing into the gas storage tank 3, the pressure inside the gas storage tank 3 gradually increases; until the pressure value rises to 0.8MPa, the pressure detection meter 6 detects the preset pressure value and feeds it back to the control chip, and the control chip controls the automatic start-stop switch to turn off the air compressor 1;

[0031] When the drinker receives the wine, the solenoid valve 7 on the gas storage tank 3 opens, and the high-pressure gas instantly enters the hose 4, flows through the pressure reducing valve 8 to reduce the air pressure of 0.8MPa to 0.1-0.3MPa, and then enters the wine barrel 5, squeezing the inner membrane of the wine barrel 5 to allow the wine to be discharged;

[0032] Therefore, such an arrangement can avoid the problem that the air pressure of the air compressor 1 is not high when it starts, causing the drinker to wait for too long;

[0033] At the same time, if the drinker does not drink much, the air pressure of 0.8MPa in the gas storage tank 3 is sufficient to attack the wine barrel 5 to output a sufficient amount of wine. At this time, there is no need to start the air compressor 1, so the number of starts of the air compressor 1 can be reduced and the service life of the air compressor 1 can be extended.

[0034] If the drinker drinks a lot of wine, the air pressure in the gas tank 3 will gradually drop from 0.8MPa, and eventually the wine barrel 5 will be unable to discharge wine due to insufficient pressure; the device also presets the start of the air compressor 1. When the air pressure in the gas tank 3 drops below 0.6MPa, the pressure detection meter 6 detects the air pressure value and transmits it to the control chip. The control chip will control the air compressor 1 to start and fill the gas tank 3 with gas;

[0035] This setting can ensure that the device always dispenses wine.

[0036] The beer barrel 5 of the device is arranged inside the direct cooling freezer 9. At present, the beer cooling in the beer barrel 5 is generally carried out by air cooling and water cooling on the market, and these two methods are relatively expensive. The direct cooling freezer 9 of the device can reduce the cost.

[0037] At the same time, the direct cooling freezer 9 can also be used as a storage cabinet when the wine barrel 5 is not placed.

[0038] Therefore, in order to facilitate the multifunctional use of the direct cooling freezer 9, the cabinet door of the direct cooling freezer 9 is hinged at the upper end of the cabinet body; such arrangement facilitates the use of the direct cooling freezer 9.

[0039] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
