Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a beverage mixing nozzle for a beverage supply device that mixes and supplies syrup and dilution water that are supplied through separate pipes.

(b) Prior Art As such a beverage mixing nozzle, there is a technology disclosed in Japanese Utility Model Publication No. 50-23037. In this system, syrup and dilution water are introduced into the mixing nozzle body through separate pipes, and the syrup and dilution water are mixed and poured out by the operation of an operating member. To give a concrete example using Fig. 2,
A syrup nozzle 6 that communicates with the syrup liquid liquid passage 12 and spouts syrup downward; and a dilution water nozzle that communicates with the dilution water liquid passage 13 and spouts dilution water so as to surround the syrup spouted from the syrup nozzle 6. 10, and when the operating member 3 is actuated, the valve body of the bottle main body 2 that is linked to this opens, and the syrup liquid from the syrup nozzle 6 and the dilution water from the dilution water nozzle 10 are mixed and poured out. . At the tip of the syrup nozzle 6,
A member 14 made of rubber or the like is attached, and has a spout 5 for spraying the syrup liquid radially downward. Further, the hollow member 7 covers the syrup nozzle 6 and the dilution water nozzle 10, and a gap 17 between the inner wall 9 of the hollow member 7 and the syrup nozzle 6 serves as a dilution water injection passage. Such spout 5 and hollow member 7
is for effectively mixing and dispensing syrup and diluting water, and a similar structure was developed in 1975.
It is also disclosed in Publication No. 44947.

(c) Problems to be solved by the invention In the above configuration, the syrup liquid is mixed with the dilution water in the mixing nozzle while colliding with the dilution water, and then is poured into the cup. However, since these mixed liquids scatter within the mixing nozzle, some of them adhere to the inside of the mixing nozzle 4 even after the liquid is poured out, and, for example, adhere to the inner wall 9 or the skirt 11 of the hollow member, causing the growth of bacteria. It was the cause of the invitation. That is, since a large amount of sugar is contained in the mixed liquid to be poured out, especially in the syrup, if the mixed liquid remains attached to the mixing nozzle 4 in the above-mentioned state for a long time, dust etc. mixed in the air will be removed. This resulted in the growth of bacteria.

Therefore, the present invention provides a beverage mixing nozzle that allows less adhesion of the mixed liquid to be dispensed.

(d) Means for Solving the Problems A cylindrical member 19 is provided which has a hole 15 at its upper end for fitting with a slope nozzle and a guide passage 16 inside, and a recess 18 is formed at its lower end. The area of the opening of the recess 18 is set larger than the area of the bottom, and the bottom has a plurality of spout ports 5' arranged in an annular shape so as to communicate with the guide passage and spray the syrup from the syrup nozzle radially downward. It is located in The cylindrical member 19, syrup nozzle 6', and dilution water nozzle 10' are housed in the hollow part, and the gap 17' between the inner wall and the cylindrical member 19 is
A hollow member 7' was further provided as a dilution water injection passage, and the length of the cylindrical member in the cylindrical direction was set so that the opening edge of the recess 18 was approximately flush with the lower end surface of the hollow member. It is something.

(e) Effect With the above structure, the syrup liquid jetted radially from the cylindrical member collides with the dilution water at the position where it exits the mixing nozzle, and there is no scattering within the mixing nozzle.

(F) Example In the figure, 1 is the main body of a beverage supply device, and the main body 1 contains a syrup such as cola and dilution water necessary to dilute the syrup to a predetermined concentration. Piping (not shown) is also housed there.
Reference numeral 2 denotes a drink dispensing pot body attached to the front surface of the main body 1, and when the above-mentioned operating member is operated, the pot body 2 works in conjunction with the operating member 3 to dispense syrup and diluted water through the main body 1. It has internally independent valve bodies (not shown) for opening and closing the syrup liquid passage 12' and the dilution water passage 13' that lead to the syrup liquid passage 12' and the dilution water passage 13'. In Fig. 5, 4' is a mixing nozzle attached to the front surface of the main body 2, and a cylindrical member 1 having the following structure is attached to the tip of the syrup nozzle 6'.
It is characterized by being equipped with 9.

That is, a cylindrical member 19 having a guide passage 16 therein has a hole 15 at its upper end into which the slope nozzle 6' fits, and a recess 18 at its lower end. The length of the cylindrical member 19 in the vertical direction is set so that when the cylindrical member 19 is fitted with the slope nozzle 6' through the hole 15, the edge of the recess 18 is approximately flush with the lower end surface of the hollow member 7'. The recess 18 is set so that its wall surface expands outward as it goes downward, and the area of its opening is larger than the area of its bottom. Further, the recess 18 communicates with the guide passage 16 and the syrup nozzle 6' through a plurality of spout ports 5' formed annularly at the bottom thereof. The spout 5' is formed so as to be inclined so as to spray the syrup from the syrup nozzle 6' radially downward. A gap 17' between the inner wall 9' of the hollow member 7' and the cylindrical member 19 becomes a dilution water injection passage.

With the above structure, the syrup liquid is radially injected diagonally downward at a predetermined angle from the spout 5', and
It is ejected from the mixing nozzle along the wall of the
The dilution water is then injected through the gap 17', and the dilution water and syrup collide and mix at the position where they exit the mixing nozzle. Therefore, since mixing is not performed inside the mixing nozzle, the beverage does not scatter inside the nozzle, and liquid adhesion is reduced.

(g) Effects of the invention According to the invention, in order to mix the syrup and dilution water at the position where they exit from the mixing nozzle,
There is no scattering of the beverage inside the nozzle, and adhesion of the beverage is prevented. Therefore, bacteria will not develop in the beverage with residual adhesion, resulting in unsanitary conditions.
