no. 1 Embodiment approach

[0046] The following is based on Figure 1 ~ Figure 3 A first embodiment of the present invention will be described. figure 1 It is a schematic configuration diagram showing the liquid supply device according to the first embodiment of the present invention. figure 2 (a) means figure 1 A schematic cross-sectional view of the circulating air bubble generating nozzle 10 in the liquid supply device of figure 2 (b) is figure 2 The sectional view along the direction I-I of (a), figure 2 (c) is figure 2 The II-II arrow sectional view of (a), figure 2 (d) is figure 2 The III-III arrow sectional view in (a). image 3 It is an explanatory diagram of the operation of the circular flow air bubble generation nozzle 10 .

[0047] (Overall Configuration of Liquid Supply Device 100)

[0048] The liquid supply device 100 mainly includes a gas cylinder 60 (pressurization unit), a pressurization pipe 61 , a drink container 62 (storage chamber), a liquid flow pipe 63 , and a cool...

no. 2 Embodiment approach

[0094] A liquid supply device (not shown) according to a second embodiment of the present invention will be described below. Figure 5 It is a schematic sectional view showing the circulation type air bubble generating nozzle 30 used in the liquid supply device according to the second embodiment. In addition, since it is the same as that of 1st Embodiment except the point which uses the circulation type air bubble generating nozzle 30, description may be abbreviate|omitted.

[0095] (Structure of Circular Air Bubble Generating Nozzle 30)

[0096] Such as Figure 5 As shown in (a), the circular flow air bubble generation nozzle 30 has a bottomed tubular bottomed member 31 as a first member with a circular cross section, and a cylindrical member as a second member that is fitted into the other end side of the bottomed member 31. 32. In addition, a substantially cylindrical space surrounded by the bottomed member 31 and the cylindrical member 32 serves as a gas-liquid circulat...

Embodiment 1

[0116] First, in Figure 6 In the liquid supply device shown, using the circulation type bubble generating nozzle shown in Example 1 of the following Table 1, 5 cups of draft beer per day in medium beer mugs were discharged within 3 days (consuming 20 L of draft beer within 2 weeks) amount). Then, remove Figure 6 For the beverage container (draft beer can) of the liquid supply device, insert a sponge sheet into the liquid supply pipe, replace it with a cleaning tank filled with tap water, flow tap water into the liquid supply pipe from the cleaning tank, and place the sponge The sheet is pushed out to the downstream of the piping. At this time, the ejection unit was removed from the cooling chamber, and the sponge sheet was pushed out until it was discharged. After the sponge sheet is discharged, the piping for liquid delivery is further rinsed with tap water. Tap water containing stains in the thus obtained piping was observed with a digital microscope (Leica DMS1000: ma...

Abstract

The invention is to provide a liquid supply device having a self-cleaning function that can reduce the frequency of cleaning inner pipes and the like, compared with conventional devices. A loop-flow-type bubble generating nozzle (10) includes a bottomed member (1) having a circular section and having a bottomed cylindrical shape, and a tubular member (2) fitted to the other end of the bottomed member (1). A substantially cylindrical space surrounded by the bottomed member (1) and the tubular member (2) serves as a gas-liquid loop-flow type agitation mixing chamber (6). The tubular member (2) has, in the center thereof, an inflow hole (7) through which liquid and gas can flow in, and a first ejection hole (8a) and a second ejection hole (8b) through which liquid and gas can be ejected. Theinflow hole (7) is formed in a tapered shape that is continuously increased in diameter from the first ejection hole (8a) in the direction of the gas-liquid loop-flow type agitation mixing chamber (6). By using fine bubbles generated by this loop-flow-type bubble generating nozzle (10), dirt on an inner wall of a cooling pipe provided inside an operating liquid supply device is removed or is prevented from depositing.

Description

technical field [0001] The present invention relates to a liquid supply device including a circular flow bubble generating nozzle that generates bubbles including fine bubbles (nanobubbles and microbubbles). Background technique [0002] The beer dispenser, which is a liquid supply device for handling beer as a beverage, of course needs to be placed under strict hygiene control, but as the number of days of use increases, beer residual liquid adheres and accumulates as stains of organic substances. Therefore, this beer dispenser needs to be cleaned regularly in order to maintain a good hygienic state. For beer dispensers, generally, in order to cool the beer as a drink, it has a structure that circulates in a passage that passes through the cooling tank, and the passage for cooling is a structurally complicated shape such as a meandering shape or a coil shape, Difficult to clean. [0003] In addition, not limited to beer dispensers, containers, parts, and pipes made of sta...
