Detailed ways

The present invention first provides a refrigeration and freezing device. Figure 1 is a schematic structural diagram of a refrigeration and freezing device according to one embodiment of the present invention. Figure 2 is a schematic side view of the refrigeration and freezing device according to one embodiment of the present invention. Referring to Figures 1 and 2, the refrigeration and freezing device 1 includes a box 10. The box 10 defines a refrigeration compartment 11 with a refrigerated storage environment and an ice container with a refrigerated storage environment for glazing food ingredients. Clothing room 12. That is to say, the ice-coat compartment 12 has a storage environment similar to that of a freezer compartment. For ordinary refrigeration and freezing devices, the temperature in the ice-coat compartment 12 can usually reach -24°C ~ -18°C; For a refrigeration and freezing device with a cold function, the temperature in the ice chamber 12 can reach -40°C or even lower, so as to freeze items to a lower temperature more quickly. The temperature in the cold storage compartment 11 can usually be 0-8°C, so that in a relatively low-temperature environment, it can not only ensure that the water on the surface of the lower-temperature items can effectively form ice coating or ice film, but also avoid The water used for glazing in the glazing chamber 12 freezes into ice or frost before it comes into contact with the items.

Furthermore, a water storage device 20 for storing cooling water is provided in the refrigeration compartment 11 . The present invention disposes the water storage device 20 in the refrigeration compartment 11, which can utilize the lower temperature environment in the refrigeration compartment 11 to maintain the temperature of the cooling water within the refrigeration compartment 11 at about 0-8°C, thus avoiding the need for cooling water to be stored in the refrigeration compartment 11. Freezing in the device 20 also makes the temperature of the cooling water low enough, which is conducive to the formation of ice coating on the surface of the quick-frozen food. Preferably, the water storage device 20 can be disposed at the bottom of the refrigeration compartment 11 so that the cooling water inside it absorbs more cold energy, thereby maintaining its temperature at about 0-4°C, which is more conducive to the cooling of the ice coat. form.

In particular, the refrigeration and freezing device 1 also includes a spray device 30 and a turning mechanism. The spray device 30 is disposed in the icing chamber 12 and communicates with the water storage device 20 to use the water in the water storage device 20 to spray the food in the icing chamber 12 to form ice coating on the surface of the food. . The flipping mechanism is disposed in the glazing chamber 12 and is configured to controllably flip the food in the glazing chamber 12 so that water can be sprayed on all surfaces of the food.

The refrigeration and freezing device 1 of the present invention has a glazing chamber 12 for glazing food. The icing chamber 12 is provided with a spray device 30. The spray device 30 can cool the cooling water in the water storage device 20. Spray onto the surface of the food in the glazing chamber 12. Since the temperature in the glazing chamber 12 is close to the freezing temperature, the cooling water on the surface of the food absorbs the cold energy and forms an ice film. Finally, ice is formed that can prevent the surface of the food from contacting the air. Clothes. In particular, a flipping mechanism is also provided in the glazing chamber 12. The flipping mechanism can controllably flip the food in the glazing chamber 12, so that water can be sprayed on all surfaces of the food, so that water can be sprayed on all surfaces of the food. A uniform ice coating layer can be formed, without increasing the number of spray devices 30 , and solves the problem in the prior art that water cannot be sprayed on part of the surface of the food material and the ice coating cannot be effectively formed.

Specifically, the water storage device 20 can be connected to the spray device 30 through a water pipe, and a control valve can be provided in the water pipe to controllably conduct the water pipe through the control valve to allow the cooling water in the water storage device 20 to flow to the spray device. The shower device 30 or the water delivery pipe is blocked to prevent the cooling water in the water storage device 20 from flowing to the shower device 30 .

In some embodiments, at least one first groove 121 is provided on the side wall of the ice chamber 12 . The flip mechanism includes at least one flip arm 40 , and each flip arm 40 has a received state of being received in the first groove 121 and an extended state of extending from the first groove 121 toward the inside of the ice room 12 .

Specifically, when it is not necessary to turn the food, the turning arm 40 of the turning mechanism is received in the first groove 121, and only when it is necessary to turn the food, the turning arm 40 is extended from the first groove 121, thereby avoiding the need to ice the food. The structure in the compartment 12 is too complex and takes up too much space, thereby preventing the user from accessing and placing food through the ice compartment 12 .

Furthermore, due to the need for refrigeration, the ice room 12 usually needs to be provided with an air supply mechanism 70 (for example, it may include an air supply port and an air supply damper) at the rear thereof to transport the cooling air flow after heat exchange by the evaporator. Therefore, the first groove 121 is preferably opened on the lateral side wall of the ice room 12 .

Furthermore, since the food items that need to be ice-coated are of different sizes, if larger food items need to be ice-coated, it may not be possible to effectively turn the food items using only one flip arm 40 . Therefore, the number of flip arms 40 is preferably two. Correspondingly, the number of the first grooves 121 is also two, and the two first grooves 121 are respectively opened on the two lateral side walls of the ice room 12 .

Figure 3 is a schematic structural diagram of a flip arm according to an embodiment of the present invention. In some embodiments, the flip arm 40 may include a first section 41 pivotally connected to the side wall of the ice compartment 12 and selectively retracted into or away from the first section 41 The second section 42 protrudes inwards and outwards, and the end of the second section 42 is provided with a clamping portion 43 for clamping food ingredients. The present invention arranges the flip arm 40 into a two-stage structure. On the one hand, it is beneficial to reduce the overall length of the flip arm 40 after shrinkage, thereby shortening the length of the first groove 121 for accommodating the flip arm 40, without the need to store ice. If the volume of the icing chamber 12 is set too large, it is conducive to the temperature in the icing chamber 12 quickly reaching the requirements, that is, it is conducive to the quick freezing of the ingredients in the icing chamber 12; on the other hand, it can also make the flip arm 40 extend. The length is enough to reach any position where the ingredients may be in the ice chamber 12, thereby meeting the purpose of turning the ingredients.

Further, the clamping part 43 may be pivotally connected to the second section 42 about a rotation axis parallel to the length direction of the flip arm 40 , and the clamping part 43 may specifically include a bottom clamping claw 431 and a top clamping claw 432 . The bottom clamping claw 431 has a flat and slender shape so as to easily extend into the bottom of the food. The top clamping claw 432 has a flat and slender claw portion and a protrusion 433 protruding downward from the lower surface of the claw portion to maintain a certain gap between the surface of the food and the claw portion when the clamping portion 43 clamps the food. .

Specifically, when the flip arm 40 first starts to extend, the clamping part 43 keeps the bottom clamping claw 431 downward and the top clamping claw 432 upward to clamp the food; after clamping the food, the clamping part 43 flips 180 degrees around its rotation axis. °Thereby, the top clamping claw 432 is at the bottom and the bottom clamping claw 431 is at the top. At this time, due to the protrusion 433 of the top clamping claw 432, the bottom area where the food has been ice-coated will not contact the bottom wall of the ice-coat chamber 12 , thereby preventing the bottom area where the ice coating has been formed on the food from contacting the cooling water on the bottom wall of the glazing chamber 12 or sticking to the bottom wall of the glazing chamber 12 . When the food is ice-coated, the clamping part 43 can directly release the food, then flip 180°, reset, shrink, and be stored in the first groove 121 again; the clamping part 43 can also be turned over while maintaining the state of holding the food. The ingredients are released after turning 180°, and then contracted and contained in the first groove 121 .

It can be understood that in some embodiments, after turning over the food, the flip arm 40 can maintain the state of clamping the food and continue to ice-coat the food until the food is completely ice-coated and the food is released or the food is released after being flipped and reset. In other embodiments, after the food is turned over, the turning arm 40 can also directly release the food, shrink and accommodate it in the first groove 121, and the cooling water will rarely or almost not be sprayed to the turning arm 40, which can avoid The turning arm 40 freezes or adheres to the food.

In some embodiments, the top wall of the ice chamber 12 is provided with a second groove 122 for accommodating the spray device 30 . The shower device 30 has a received state of being received in the second groove 122 and an extended state of extending downward from the second groove 122 . When there is no need to spray cooling water on the food, the spray device 30 is accommodated in the second groove 122, and only when the food needs to be turned over, the spray device 30 is extended from the second groove 122, thereby avoiding the risk of icing. The structure in the compartment 12 is too complex and takes up too much space, thereby preventing the user from accessing and placing food through the ice compartment 12 .

Specifically, the spray device 30 may be a spray head.

In some embodiments, the top wall of the ice room 12 is provided with a slide rail 123 for guiding the sliding of the spray device 30 . The spray device 30 is configured to slide horizontally along the slide rail 123 while spraying water on the food. As a result, the spray device 30 can spray cooling water to various positions of the food in a sliding manner, which is especially suitable for larger-volume food and further improves the uniformity of the glaze layer on the surface of the food.

Specifically, the slide rail 123 may extend transversely of the ice room 12, may extend in the front-rear direction, or may extend obliquely.

In some embodiments, the refrigeration and freezing device 1 further includes a drainage device 50 , one end of which is connected to the bottom of the ice-coat chamber 12 , and the other end is connected to the evaporator 60 of the refrigeration and freezing device 1 , so as to drain the water at the bottom of the ice-coat chamber 12 . The water is discharged to evaporator 60. When ice coating is performed by spraying, excess water will inevitably flow to the bottom of the ice coating chamber 12. If it is not discharged in time, it may freeze at the bottom of the ice coating chamber 12, affecting the ice coating of the food. By arranging the drainage device 50 connected to the bottom of the ice chamber 12, the present invention can discharge the excess cooling water at the bottom of the ice chamber 12 to the evaporator 60 in a timely manner, thereby preventing the bottom of the ice chamber 12 from freezing. For the purpose, this part of the cooling water can be used to defrost the evaporator 60 (the temperature of the cooling water is still higher than that of the evaporator 60), and finally the refrigeration and freezing device 1 can be discharged through the water tray and drainage device. .

In some embodiments, a food placement area 124 for placing food is provided at the bottom of the ice chamber 12. The food placement area 124 is arranged to be inclined according to a preset angle, and the drainage device 50 is connected to the lowest part of the food placement area 124. The inclined arrangement of the food placement area 124 allows excess cooling water on the food placement area 124 to drain away in time, thereby preventing the cooling water remaining in the food placement area 124 from affecting the formation of ice coating on the food materials or forming a thicker ice coating layer on the food materials.

Specifically, the food placement area 124 may be a liftable bracket.

In some embodiments, one or more of the spray device 30 , the turning mechanism, and the food placement area 124 are provided with a heating device to prevent the spray device 30 from being blocked, the turning mechanism from adhering to the food, and the food placement area 124 from being blocked. Ice etc.

The present invention also provides a control method for a refrigeration and freezing device, which is used for the refrigeration and freezing device 1 described in any of the above embodiments.

Since the temperature in the freezing chamber 12 is close to the freezing temperature, the cooling water on the surface of the food absorbs the cold energy and forms The ice film eventually forms an ice coating that prevents the surface of the food from coming into contact with the air. The turning mechanism can turn over the food in the ice coating chamber 12 after the ice coating is carried out for the first preset period of time, so that the surface of the food that is not sprayed can also be sprayed with water, so that an even surface can be formed on all surfaces of the food.
