DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a frozen dessert manufacturing apparatus for manufacturing and selling shakes, soft serve ice cream, and the like.

(B) Conventional technology Frozen dessert manufacturing equipment that manufactures frozen desserts such as ice cream and shakes generally has a raw material tank into which the raw material mix is placed before sale, a freezing cylinder that cools and stirs the mix, and a frozen dessert manufacturing device that manufactures frozen desserts such as ice cream and shakes. The inside of the freezer door, including extraction parts and syrup introduction holes, etc., must be sterilized before operation and sale. Also, at the end of business hours on the following day, it is necessary to take out the remaining products and mixes, wash the inside of the machine, and clean the surfaces outside the machine to keep it clean to prevent the growth of germs. As seen in Japanese Utility Model Application Publication No. 53-2289, these sterilizations and cleanings are carried out by putting water, a disinfectant, or a cleaning agent into a tank or cylinder, and washing the dasher inside the cylinder by rotating it. Then, open the product extraction port,
The sterilized and washed water is drained and cleaned.

After that, the inside is disassembled, each passage inside the door is cleaned with a brush, etc., and the surface of the freezer door is also cleaned with a brush, etc.

(c) Problems to be Solved by the Invention However, in the conventional method described above, the inside of the hole through which the extraction member is inserted in the freezer door or the inside of the syrup supply port is not filled with cleaning water when it is drained from the cylinder. Since it is not possible to clean the freezer first, the interior must be disassembled and cleaned, such as by removing the freezer door and pulling out the extraction member.

Also, the surface of the freezer door cannot be cleaned automatically. in this way.

The drawback was that the freezer door had to be disassembled and cleaned, requiring a lot of effort and time to clean.

An object of the present invention is to provide a frozen dessert manufacturing apparatus that allows washing water discharged from a freezing cylinder to be distributed to each passage inside the door and the surface of the door automatically without removing the freezer door. purpose.

(d) Means for Solving the Problems The frozen dessert manufacturing apparatus according to the present invention utilizes an opening that communicates with the outside that is created when a member for extracting frozen desserts is removed from the freezer door, and performs cleaning from this opening. At times, washing water overflows from the freezing cylinder, and a washing water receiving box that receives this washing water can be attached to the freezer door.

(When the stirring member inside the phantom freezing cylinder is rotated and the inside of the cylinder is washed, the washing water flows through the freezer door and flows through the opening that communicates with the outside of the door when the frozen dessert extraction port is opened. It overflows.At this time, the cleaning water flows through the insertion hole of the extraction member and the syrup supply hole, and the remaining mix and syrup are washed away.The overflowing cleaning water collects in the cleaning water receiving box. Water is gradually drained from a drainage hose, etc. Then,
This overflowing washing water travels over the surface of the freezer door, naturally washing the door surface clean.
