Description

Technical Field

[0001] This application relates to the field of quick-freezing technology, and more particularly to a quick-freezing apparatus. Background Technology

[0002] Existing quick-freezing devices achieve quick-freezing of items by circulating cold air generated by the evaporator to the freezing zone of the food items awaiting freezing. When the refrigerant circulating in the refrigeration system leaks, such as due to damaged or aged pipes or seals, the refrigerant may leak into the freezing zone of the items and come into contact with them. Simultaneously, it may cause the temperature in the freezing zone where the items are located to rise, providing conditions for bacterial growth and further increasing the risk of food poisoning and other food contamination.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0004] This application provides a quick-freezing device to address the safety risk of contamination of items to be quick-frozen in existing quick-freezing devices.

[0005] In a first aspect, this application provides a quick-freezing device for quick-freezing items to be quick-frozen. The quick-freezing device includes a base, an evaporation component sleeved on the base, an air duct component connected to the evaporation component, a detachable storage component, and an outer cover covering the base and the air duct component.

[0006] Optionally, the evaporation assembly includes an evaporator built into the base, a bracket configured corresponding to the evaporator and connected to the base, and an evaporation fan disposed on top of the bracket.

[0007] Optionally, the base is provided with one or more baffles, and the evaporator is disposed in the space enclosed by the baffles.

[0008] Optionally, the base is provided with an outer peripheral surface protruding from its bottom surface and surrounding the grid member, and the bracket is engaged with the base through the gap between the grid member and the outer peripheral surface.

[0009] Optionally, the bracket has an upward-opening receiving groove at the end away from the base, and the evaporator fan is disposed in the receiving groove.

[0010] In a sixth aspect, this application provides a quick-freezing device, wherein the air duct assembly includes an inner air duct disposed corresponding to the top of the evaporation assembly and an outer air duct surrounding the outer periphery of the inner air duct and connected to the outer periphery of the base.

[0011] Optionally, a return air hole is provided at the end of the inner air duct away from the evaporation component, and the inner air duct and the outer air duct are connected through the return air hole.

[0012] Optionally, the return air vents are longitudinal through holes, evenly arrayed at the end of the inner air duct away from the evaporation component.

[0013] Optionally, the detachable storage assembly includes a storage component that can be suspended inside the air duct assembly and a storage cover that covers the opening at the top of the storage component.

[0014] Optionally, the top of the removable storage assembly is exposed at the center of the outer casing.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art:

[0016] 1. When using the device, the user can place the food items to be frozen into the detachable storage component, which is in the disassembled state. Then, the user can install the detachable storage component into the quick-freezing device and perform a quick-freezing operation on the items placed inside. The separate setting makes the quick-freezing process safer.

[0017] 2. The evaporation component is located at the bottom of the quick-freezing device, and the cold air generated by the evaporator is sent from bottom to top by the evaporation fan to the upper middle part of the quick-freezing device to achieve quick-freezing operation.

[0018] 3. The space enclosed by the baffle can be used to accommodate the evaporator, and the baffle can limit the evaporator to ensure that the evaporator stably generates cold air.

[0019] 4. The space formed by the connection between the bracket and the base provides a relatively enclosed installation space for the evaporator, and also further enhances the connection stability between the components.

[0020] 5. The cold air generated by the evaporator is blown by the evaporation fan into the space formed by the inner air duct and the removable storage component. The cold air flows along the inner air duct and the outer wall of the removable storage component from the return air hole to the outer air duct, and then flows back to the evaporation component from the outer air duct. This cycle repeats. Through the design of the air duct system, heat transfer is used to allow the heat of the items to be quick-frozen inside the removable storage component to be lost, thereby achieving a quick-freezing effect.

[0021] 6. By setting the return air holes, the connectivity between the inner and outer air ducts is ensured, and the heat transfer efficiency is improved based on the air duct design, thereby accelerating the freezing speed; the longitudinal through holes follow the upward movement direction of the cold air, further enhancing the flow effect of the cold air.

[0022] 7. The cold air generated by the storage unit and the evaporation component is physically separated to prevent the items to be quick-frozen from coming into contact with the chemicals generated during the quick-freezing process, so that the items to be quick-frozen will not be contaminated and the safety of the quick-freezing process is improved. At the same time, the design of the air duct system is also conducive to taking into account the quick-freezing effect. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0033] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0034] In order to solve the technical problems in the prior art, this application provides a quick-freezing device 1 to solve the safety risk of contamination of the items to be quick-frozen by the existing quick-freezing devices.

[0035] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a quick-freezing device 1 for quick-freezing items. The quick-freezing device 1 includes a base 11, an evaporation assembly 12 sleeved on the base 11, an air duct assembly 13 connected to the evaporation assembly 12, a detachable storage assembly 14, and an outer cover 15 covering the base 11 and the air duct assembly 13.

[0036] It is understood that when using the device, users can place food items waiting to be frozen into the detachable storage component 14 in the disassembled state, and then install the detachable storage component 14 into the quick-freezing device 1 and perform a quick-freezing operation on the items placed inside. The separate setting makes the quick-freezing process safer.

[0037] Please combine Figure 3 and Figure 4 The evaporation assembly 12 includes an evaporator 121 built into the base 11, a bracket 122 configured corresponding to the evaporator 121 and connected to the base 11, and an evaporation fan 123 disposed on the top of the bracket 122.

[0038] It is understood that the evaporation component 12 is located at the bottom of the quick-freezing device 1, and the cold air generated by the evaporator 121 is sent from bottom to top by the evaporation fan 123 to the upper middle part of the quick-freezing device 1 to achieve quick-freezing operation.

[0039] Specifically, in the embodiments of this application, one or more baffles 111 are provided inside the base 11, and the evaporator 121 is disposed in the space enclosed by the baffles 111. It can be understood that the space enclosed by the baffles 111 can be used to accommodate the evaporator 121, and the baffles 111 can limit the evaporator 121, thereby ensuring that the evaporator 121 stably generates cold air.

[0040] Please continue to combine Figure 3 and Figure 4 The base 11 has an outer peripheral surface 112 protruding from its bottom surface and surrounding the baffle 111. The bracket 122 is engaged with the base 11 through the gap between the baffle 111 and the outer peripheral surface 112. Furthermore, the bracket 122 has an upward-opening receiving groove 1221 at its end away from the base 11, and the evaporator fan 123 is disposed in the receiving groove 1221. It can be understood that the space formed by the connection between the bracket 122 and the base 11 provides a relatively enclosed installation space for the evaporator 121, and also further enhances the connection stability between the components.

[0041] Please combine Figure 2 , Figure 3 and Figure 4The air duct assembly 13 includes an inner air duct 131 disposed corresponding to the top of the evaporation assembly 12 and an outer air duct 132 disposed around the outer periphery of the inner air duct 131 and connected to the base 11. The inner air duct 131 has a return air hole 1311 at the end furthest from the evaporation assembly 12, and the inner air duct 131 and the outer air duct 132 are connected through the return air hole 1311.

[0042] It is understood that the cold air generated by the evaporator 121 is blown by the evaporation fan 123 into the space formed by the inner air duct 131 and the removable storage component 14. The cold air flows along the inner air duct 131 and the outer wall of the removable storage component 14 from the return air hole 1311 to the outer air duct 132, and then flows back to the evaporation component 12 from the outer air duct 132. This cycle repeats. Through the design of the air duct system, heat transfer is used to allow the heat of the items to be quick-frozen inside the removable storage component 14 to be lost, thereby achieving a quick-freezing effect.

[0043] Optionally, the return air vent 1311 is a longitudinal through-hole, evenly arrayed at the end of the inner air duct 131 away from the evaporator assembly 12. By setting the return air vent 1311, the connectivity between the inner air duct 131 and the outer air duct 132 is ensured, and the heat transfer efficiency is improved based on the air duct design, accelerating the freezing speed; the longitudinal through-hole follows the upward movement direction of the cold air, further enhancing the flow effect of the cold air.

[0044] Please continue reading Figure 2 , Figure 3 and Figure 4 The detachable storage assembly 14 includes a storage component 141 that can be suspended inside the air duct assembly 13 and a storage cover 142 that covers the top opening of the storage component 141. Specifically, the top of the detachable storage assembly 14 is exposed at the center of the outer cover 15.

[0045] Specifically, when the storage component 141 is placed inside the air duct assembly 13, the top end of the air duct assembly 13 abuts against the edge of the top opening of the storage component 141, that is, the top diameter of the storage component 141 is larger than the top diameter of the air duct assembly 13. Since the outer cover 15 covers the outer periphery of the base 11 and the air duct assembly 13, the top diameter of the storage component 141 is larger than the diameter of the hollow part at the top of the outer cover 15.

[0046] Optionally, in the embodiments of this application, the storage component 141 is made of stainless steel; the outer cover 15 is made of polystyrene.

[0047] It is understood that the cold air generated by the storage component 141 and the evaporation component 12 is physically separated to prevent the items to be quick-frozen from coming into contact with the chemical substances generated during the quick-freezing process, so that the items to be quick-frozen will not be contaminated and the safety of the quick-freezing process is improved. At the same time, the design of the air duct system is also conducive to taking into account the quick-freezing effect.

[0053] 5. The cold air generated by the evaporator is blown by the evaporation fan into the space formed by the inner air duct and the removable storage component. The cold air flows along the inner air duct and the outer wall of the removable storage component from the return air hole to the outer air duct, and then flows back to the evaporation component from the outer air duct. This cycle repeats. Through the design of the air duct system, heat transfer is used to allow the heat of the items to be quick-frozen inside the removable storage component to be lost, thereby achieving a quick-freezing effect.

[0054] 6. By setting the return air holes, the connectivity between the inner and outer air ducts is ensured, and the heat transfer efficiency is improved based on the air duct design, thereby accelerating the freezing speed; the longitudinal through holes follow the upward movement direction of the cold air, further enhancing the flow effect of the cold air.
