[0021] Example: See Figures 1 to 4 As shown, the rapid cooling mechanism of the oven for pastry production includes the box body 1 of the oven. A carrying rack 2 is arranged in the baking chamber of the box body 1. The carrying rack 2 includes a vertical water inlet pipe 21 and a water outlet pipe 22 located at the rear side of the baking chamber. In the baking chamber in front of the water inlet pipe 21 and the water outlet pipe 22, a number of vertically and evenly distributed brackets 23 are arranged. The bracket 23 includes two longitudinal fixed insertion pipes 231. The rear ends of the fixed insertion pipes 231 are respectively fixed on the water inlet pipe 21 and the water outlet pipe 22 and are respectively communicated with the water inlet pipe 21 and the water outlet pipe 22; A movable sleeve 232 is sleeved on the fixed insertion pipe 231. A number of longitudinally distributed horizontal pipes 233 which are communicated with the movable sleeve 232 are inserted and fixed between the movable sleeves 232. A water passing hole 2311 opposite to the horizontal pipe 233 is formed on the side wall of the fixed insertion pipe 231 close to the horizontal pipe 233; The front end of the movable sleeve 232 extends out of the fixed insertion pipe 231 and is inserted and fixed with a "C"-shaped pull handle 235;

[0022] A number of longitudinally distributed support seats 234 are sleeved on the movable sleeve 232 of the bracket 23. The support seat 234 includes an arc-shaped collar sleeved on the movable sleeve 232. A T-shaped connecting seat is formed on the outer wall of the collar. The connecting seats are respectively fixed on the side walls on both sides of the baking chamber of the box body 1.

[0023] The horizontal pipes 233 are longitudinally and evenly distributed linearly on the bracket 23. An opening opposite to the horizontal pipe 233 is formed on the pipe wall of the movable sleeve 232; The inner diameter of the movable sleeve 232 is equal to the outer diameter of the fixed insertion pipe 231. When the carrying rack 2 is cooled by cooling water, water leakage between the movable sleeve 232 and the fixed insertion pipe 231 is avoided.

[0024] The support seats 234 are evenly distributed linearly on the movable sleeve 232. The diameter of the inner wall of the collar on the support seat 234 is equal to the diameter of the outer wall of the movable sleeve 232; An avoidance notch 2341 is formed on the support seat 234 in the middle and rear parts of the movable sleeve 232. A limit stop block 239 opposite to the avoidance notch 2341 is fixed on the outer wall at the rear end of the movable sleeve 232. The stop block 239 is inserted into the avoidance notch 2341 of the support seat 234. The longitudinal section of the limit stop block 239 is the same as the longitudinal section of the avoidance notch 2341. When the bracket 23 is pulled outwards, the limit stop block 239 is finally restricted by the support seat 234 in front of the oven, avoiding the movable sleeve 232 from detaching from the front end of the fixed insertion pipe 231.

[0025] The handle 235 is formed by bending a metal pipe. The two ends of the handle 235 are formed with expanded pipes 2351. The expanded pipes 2351 are inserted and fixed at the front end of the moving sleeve 232. The inner diameter of the handle 235 is smaller than the inner diameter of the fixed insertion pipe 231, which is beneficial for cooling water to enter the cross pipe 233 from the water through hole 2311.

[0026] A circular positioning sleeve 236 is pivotally connected inside the moving sleeve 232 on the front side of the fixed insertion pipe 231. An inner ring on the rear side of the positioning sleeve 236 is formed with a valve pipe 2361 extending backward. The valve pipe 2361 is inserted into the fixed insertion pipe 231 and is formed with a water trough opposite to the water through hole 2311; a spiral guiding groove 2362 extending to the outer wall of the valve pipe 2361 is formed on the outer wall of the positioning sleeve 236, and a longitudinal groove 2363 connected to the spiral guiding groove 2362 and in a straight line is formed on the outer wall of the valve pipe 2361;

[0027] The front end of the fixed insertion pipe 231 is inserted and fixed with a positioning pin 238. The end of the positioning pin 238 is inserted into the spiral guiding groove 2362 of the valve pipe 2361. In order to prevent the water through hole 2311 on the fixed insertion pipe 231 from being exposed and leaking when the moving sleeve 232 moves outward, the valve pipe 2361 structure is provided. When the moving sleeve 232 moves outward, the positioning pin 238 is different. When the valve pipe 2361 moves with the moving sleeve 232, it rotates under the action of the positioning pin 238. Furthermore, the valve pipe 2361 will close the water through hole 2311 on the fixed insertion pipe 231 to prevent the water through hole 2311 from leaking.

[0028] The outer diameter of the outer wall of the valve pipe 2361 is equal to the inner diameter of the inner wall of the fixed insertion pipe 231;

[0029] The outer wall of the positioning sleeve 236 abuts against the inner wall of the moving sleeve 232. Limiting retaining rings 237 are respectively abutted on the front and rear end faces of the positioning sleeve 236. The limiting retaining rings 237 are inserted and fixed inside the moving sleeve 232.

[0030] Sealing plates are respectively fixed at the upper end of the water inlet pipe 21 and the lower end of the water outlet pipe 22. The lower end of the water inlet pipe 21 is connected to a cooling water source through a pipeline. The upper end of the water outlet pipe 22 is connected to a water tank through a pipeline; all cooling water sources can be tap water. The water inlet pipe 21 is connected to a tap water pipeline through a pipeline, but a solenoid valve is provided on the connecting pipeline. The water pressure of tap water can enable the cooling water to flow inside the carrier 2 to quickly cool the carrier 2.

[0031] Working principle: The carrier 2 in the rapid cooling mechanism of the oven for pastry production in this structure is made of pipe fittings. There is an internal cooling flow channel inside it. Cooling water can enter from the water inlet pipe 21, flow into the fixed insertion pipe 231 to take away the heat on the moving sleeve 232. At the same time, it can flow into the horizontal pipe 233 through the water passing holes 2311 to take away the heat of the horizontal pipe 233, and finally be discharged from the water outlet pipe 22. The rapid cooling of the carrier 2 can be achieved by using water flow.

Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of the rights protection of the present invention should be as listed in the claims of the present invention.
