Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a frozen dessert making machine that manufactures so-called frozen desserts such as soft serve ice cream, ice cream shake, slush ice cream, and semi-frozen carbonated drinks. This invention relates to a drain container and a cleaning device for a drain pipe connected to the drain container.

(b) Conventional technology As a conventional technology, Japanese Utility Model Application No. 53-22893 discloses
A support body is fitted via a spring into a socket at the upper end of a drain pipe fixed directly below the front of the machine body so that it can be raised and lowered, and the lower end of a connecting drain pipe of a predetermined length is expanded and contracted into the socket. A drainage device for washing an ice cream making machine is disclosed which is freely inserted and supported and whose upper end is fitted and connected to a product outlet at the front.

(c) Problems to be solved by the invention The inlet and drain pipe of the prior art are used to drain dirty washing water inside the cooling cylinder to the outside of the machine, or to serve as a product outlet when selling the product. The problem is that dirty washing water and frozen desserts adhere to the inside of the receptacle and the drain pipe, which rots and causes foul odors and mold, resulting in unsanitary conditions. The point was hot.

In view of these problems, the present invention provides a cleaning device for a frozen dessert making machine that cleans a drain container and a drain pipe corresponding to a socket with fresh water.

(d) Means for Solving the Problems In order to solve the problems of the above-mentioned prior art, the present invention has a structure in which a frozen confectionery outlet is formed on the lower surface of the freezer door provided at the front of the cooling cylinder, and In a frozen dessert manufacturing machine comprising a top-opening drain container fixed to the front of the machine body and a drain pipe connected to the bottom of the container, a water-cooled condenser that constitutes a refrigeration cycle together with an evaporator provided in the cooling cylinder is provided. provided, and an opening at the outlet side end of the cooling water pipe of the condenser,
This is a cleaning device for a frozen dessert making machine, which is arranged so as to protrude from the front of the machine body and face the drain container.

(E) Effect According to the present invention, the warm fresh water that has passed through the condenser 21 is sprayed into the drain container 10 from the outlet end opening 24A of the cooling water pipe 24, and then flows through the drain pipe 11 to the machine. Drained outside. This results in
Mix or syrup adhering to the drain container 10 and drain pipe 11 can be washed away.

(f) Examples Examples of the present invention will be described below based on the drawings. 1 cools the frozen dessert stock solution supplied via the supply device 3 from the stock solution tank 2 connected in a communicating state, and stirs it with the stirring device 4 installed inside, thereby producing, for example, soft serve ice cream. It is a cooling cylinder, and an evaporator 5 of a refrigeration cycle is connected to its outer circumferential surface, and its front portion is closed by a freezer door 6 equipped with a take-out mechanism. A take-out port 8 for frozen desserts to be extracted by operating a take-out lever 7 is formed on the bottom surface of the freezer door 6, and a drain opening 8 is provided on the front plate 9A of the body 9 below the take-out port 8. A container 10 is fixedly installed. A drain pipe 11 is connected to the bottom of the drain container 10 to guide waste water out of the aircraft body. The drive shaft 12 for the agitation device 4 is inserted through the rear wall of the cooling cylinder 1 via a bearing 13 and is connected to a reducer 15 via a joint 14, which is connected to a large pulley 16, an endless It is connected to a drive motor 19 via a belt 17 and a small pulley 18,
Thereby, the rotation of the motor 19 is transmitted to the stirring device 4.

The refrigeration cycle includes an electric compressor 20, a water-cooled condenser 21, the evaporator 5, a capillary tube 22 as a pressure reducing device, and a cooling solenoid valve 23 connected in an annular manner, and the condenser having a double pipe structure. The cooling water pipe 24 that cools the refrigerant by passing water through the pipe 21 has a water-saving valve 25 connected to the inlet side, and has an end opening 24A on the outlet side protruding from the front plate 9A of the fuselage 9 to connect to the drain container 10. It is placed facing the In addition, the first
A communication pipe 26 shown by a dashed line in the figure communicates the outlet 8 and the drain pipe 11 when cleaning the cooling cylinder 1.
This is set when cleaning water in the cooling cylinder 1 is drained.

In the above configuration, the cooling water that passes through the condenser 21 through the cooling water pipe 24 during the cooling movement exchanges heat with the refrigerant, and becomes hot water at about 40°C. This clean hot water is sprinkled into the drain container 10 from the end opening 24A of the cooling water pipe 24, and then drained out of the machine through the drain pipe 11. As a result, the mix that drips into the drain container 10 from the outlet 8, the mix that flows from the drain container 10 into the drain pipe 11 and adheres to the inner surface of the pipe, and furthermore, the
The mixture adhering to the inner surface of the drain pipe 11 can be thoroughly washed away by passing the dirty wash water drained from the drain pipe 26 through the communication pipe 26.

(g) Effects of the invention As described above, the present invention effectively utilizes the cooling wastewater used in the water-cooled condenser, and can wash away the mixture or syrup that has adhered to the drain container and drain pipe. It prevents bad odors and the growth of mold, and is extremely effective in terms of hygiene management.

In addition, since the clean water is heated by passing through the condenser, it is possible to wash away fat-containing mixes and sugar-containing syrup very well.

Furthermore, by first releasing the waste water from the condenser to the atmosphere and then discharging it into the drain pipe, it is possible to prevent contamination of the inlet side of the cooling water pipe, that is, the tap water, even if the drain pipe becomes clogged. .
