Description

Technical Field

[0001] The invention relates to the technical field of freezers, and in particular to an energy-saving quick-freezing freezer for prepared dishes with adjustable capacity and multiple independent anti-odor storage chambers. Background Art

[0002] Patent application number CN202320372156.7 discloses a detachable door panel linkage handle for refrigerators and freezers. The handle comprises at least two door panels arranged on the same hinge axis of the refrigerator or freezer. The two adjacent door panels are respectively provided with handle mounting holes. The ends of the linkage handle are respectively installed in the mounting holes of the corresponding door panels, so that the two door panels are linked together. By installing the door panel linkage handle, the door panels of the refrigerator and freezer can open and close multiple doors synchronously. This can increase independent storage compartments and reduce the risk of food odor transfer in the refrigerator. This allows the refrigerator to have the best anti-odor effect while reducing the number of door openings of multi-door refrigerators and freezers, making it easier to store and retrieve food and improving the efficiency of refrigerator use.

[0003] Traditional refrigerators and freezers generally use fixed independent storage compartments to prevent food from odor transfer, such as the above-mentioned existing technology. However, this design has significant drawbacks: Poor spatial flexibility: The storage compartments have a fixed volume and cannot accommodate pre-prepared meal packages of different sizes, resulting in low space utilization. Low operating efficiency: The door needs to be opened and closed repeatedly to take food in and out, resulting in a large amount of cold air leakage and increased energy consumption; Incomplete odor prevention: Cold air directly contacts the food circulation, and odor molecules are easily diffused with the airflow. Existing technologies cannot completely prevent odor transfer by simply using physical separation; Therefore, there is an urgent need for a quick-freeze storage cabinet that has adjustable capacity, high efficiency in preventing odor contamination, and energy saving. Summary of the Invention

[0004] In order to overcome the defects in the prior art, the purpose of the present invention is to provide an energy-saving pre-prepared food quick-freezing freezer with adjustable capacity and multiple independent anti-odor storage chambers. The dynamic capacity adjustment design is set to adapt to the storage of pre-prepared foods of different volumes, the zero ventilation anti-odor design is set to enable multiple ingredients to coexist without odor contamination, and the energy-saving quick-freezing enhanced design is set to achieve improved quick-freezing efficiency and uniform utilization of cold capacity, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides an energy-saving quick-freezing freezer for prepared meals with adjustable capacity and multiple independent anti-odor storage chambers, comprising a plurality of storage chambers embedded side by side within the freezer body and a drive device installed on both sides of the freezer body for driving the storage chambers to rise and fall; The interior of the freezer body is fixedly connected to a cavity member for dividing the interior space of the freezer body into a plurality of independent cavities of equal volume. The storage cabinet includes a cabinet cover snap-fitted to the top of the freezer body, a pair of wall cabinets symmetrically suspended below the cabinet cover, a plurality of upper partitions slidably arranged on the upper layer of the wall cabinets, and a plurality of lower partitions slidably arranged on the middle and lower layers of the wall cabinets. The wall cabinets are adapted to snap-fit into the independent cavities. A plurality of isolation layers are horizontally spaced apart between the two vertical side walls of the wall cabinets. A ventilation cavity is formed through the side of the isolation layer. The interior of the cavity member is a hollow structure with an opening at the bottom thereof for guiding cold air into the plurality of ventilation cavities to quickly freeze the pre-prepared dishes placed on the isolation layers. The two side ends of the cabinet cover are extended downward to provide a support plate, and the driving device includes a guide cover installed on the side shell plate of the refrigerator body, a transmission screw threadedly connected to the bottom of the support plate, and a servo motor for driving the transmission screw to rotate; the support plate and the guide cover are adapted to be slidably plugged in.

[0006] The above setting takes into account that a large amount of cold air is easily dissipated when taking and placing ingredients, resulting in high energy consumption. In addition, since the volumes of ingredients are different, a dynamic capacity adjustment storage cabinet is designed. Upper and lower partitions with adjustable spacing are slidingly set in the wall cabinet to freely adjust the width of the storage layer inside the wall cabinet, so as to adapt to the storage of pre-prepared dishes of different volumes; a distributed path for cold air is set between the wall cabinet and the main body of the freezer through the ventilation grooves and ventilation holes to complete the three-dimensional circulation of cold air around the pre-prepared dishes. When the wall cabinet is lifted, its bottom surface forms a blocking effect, so as to achieve the energy-saving effect of improving the quick-freezing efficiency and uniform use of cold capacity.

[0007] As a further improvement of the present technical solution, the partition member is composed of a pair of transverse partitions and at least one longitudinal partition vertically connected, and the independent cavity of equal volume is an independent space enclosed by the pair of transverse partitions, the longitudinal partitions and the inner side of the freezer body.

[0008] As a further improvement of the present technical solution, a plurality of ventilation grooves are provided on both side walls of the transverse partition at positions corresponding to the plurality of isolation layers. The ventilation grooves are connected to the internal cavity of the transverse partition and are arranged opposite to the ventilation cavity.

[0009] As a further improvement of the present technical solution, the interior of the ventilation cavity is adapted to be connected with a reinforcing rod, and a plurality of ventilation holes are formed through the side wall of the reinforcing rod for guiding the cold air to pass through.

[0010] The above arrangement allows cold air to be distributed around the pre-prepared dishes and freeze them quickly. At the same time, the cold air only circulates inside the isolation layer and the cavity, avoiding ventilation with the internal space of the wall cabinet, thereby completely avoiding the contamination of the pre-prepared dishes.

[0011] As a further improvement of the present technical solution, the cabinet cover is a rectangular frame with a glass plate installed inside, the long side of the bottom surface of the cabinet cover is fixedly connected to a hanging rail, the longitudinal section of the hanging rail is wide at the bottom and narrow at the top, and the top corners of the upper partition are symmetrically provided with card slots, and the card slots are adapted to slide and snap into place with the hanging rail.

[0012] This setting allows the upper partitions to slide and be distributed between the upper layers of the wall cabinets. The spacing between several upper partitions can be adjusted according to needs to place dishes of different capacities.

[0013] As a further improvement of this technical solution, a forming frame is clamped between the corners of the two adjacent upper and lower isolation layers, a guide rail is clamped between the tops of a pair of relatively arranged forming frames, and a sliding groove is provided in the middle of the top surface of the lower partition for sliding engagement with the guide rail.

[0014] As a further improvement of the present technical solution, the longitudinal section of the guide rail is wide at the bottom and narrow at the top, the upper and lower ends of the forming frame are tripod structures and a slot is provided in the middle of the top surface, and the ends of the guide rail are adapted to be plugged into the slot.

[0015] These two settings allow the lower partitions to slide and be distributed between the middle and lower layers of the wall cabinets. The spacing between several lower partitions can be adjusted according to needs to place dishes of different capacities.

[0016] As a further improvement of the present technical solution, the bottom end of the support plate is bent into a horizontal section and a threaded hole is opened on its top surface. The transmission screw is threadedly connected to the threaded hole. The outer edge of the horizontal section of the bottom end of the support plate is rotatably connected to a roller through a pin, which is used for rolling connection with the side shell plate of the freezer body.

[0017] As a further improvement of the present technical solution, partition plates are fixedly connected to the inner side of the guide cover at equal intervals, and the support plate is adapted to be plugged and slidably connected with two adjacent partition plates.

[0018] As a further improvement of the present technical solution, the servo motor is installed on the bottom surface of the refrigerator main body shell, and the upper and lower ends of the transmission screw are provided with fixing frames, and the two ends of the fixing frames are plugged into the side walls of the partition plate.

[0019] The above-mentioned arrangement guides the lifting and lowering of the limiting support plate through the guide cover and a pair of partition plates, and guides the support plate to lift and lower vertically under the action of the transmission screw through the rolling contact of the roller against the outer surface of the freezer body; the support plate is driven to lift and lower by the transmission screw, thereby lifting the wall cabinet and pre-prepared dishes to expose them above the freezer body, so that the pre-prepared dishes can be taken and placed.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. This energy-saving quick-freezing freezer for prepared meals with adjustable capacity and multiple independent anti-odor storage chambers adopts a dynamic capacity adjustment design: upper and lower partitions with adjustable spacing are slidingly set inside the wall cabinet to freely adjust the width of the storage layer inside the wall cabinet, achieving the technical effect of adapting to the storage of prepared meals of different volumes and improving space utilization.

[0021] 2. This energy-saving quick-freezer for prepared meals with adjustable capacity and multiple independent anti-odor storage chambers has a zero-ventilation anti-odor design: the partitions are connected to the isolation layer with a closed cold circulation channel, so that the cold air circulates only inside the isolation layer and avoids entering the food storage space, achieving the technical effect of completely blocking the diffusion of odor molecules and enabling multiple foods to coexist without odor.

[0022] 3. This energy-saving quick-freezing freezer for prepared meals with adjustable capacity and multiple independent anti-odor storage chambers has an enhanced energy-saving quick-freezing design: the spacing design between the bottom of the wall cabinet and the bottom of the freezer body and the distributed path of cold air through the ventilation grooves and air holes complete the three-dimensional circulation of cold air around the prepared meals, achieving energy-saving effects such as improved quick-freezing efficiency and uniform use of cold energy.

[0023] 4. This energy-saving quick-freezing freezer for prepared meals with adjustable capacity and multiple independent anti-odor storage chambers is equipped with a drive device to link the transmission screw to lift the support plate, so that the storage cabinet can be independently raised to the top of the freezer body to take and place food. The convenience of storage and access is improved, and the technical effect of reducing cold air leakage and lowering energy consumption is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, in the description of the present invention, "several" means two or more, unless otherwise specifically defined.

[0028] See also Figure 1-Figure 4As shown, the present invention provides an energy-saving quick-freezing freezer for prepared meals with adjustable capacity and multiple independent anti-odor storage cavities, including a plurality of storage cabinets 200 embedded side by side inside a freezer main body 100 and a driving device 300 installed on both sides of the freezer main body 100, for driving the storage cabinets 200 to rise and fall; the prepared meals are stored in the plurality of storage cabinets 200 and, driven by the driving device 300, are lowered into the freezer main body 100 for freezing.

[0029] A cavity partition 110 is fixedly connected to the interior of the refrigerator body 100 for dividing the interior space of the refrigerator body 100 into a number of independent cavities of equal volume so that the pre-prepared dishes placed in the independent cavities do not mix with each other's flavors.

[0030] The storage cabinet 200 includes a cabinet cover 210 that is snap-connected to the top of the freezer body 100, a pair of wall cabinets 220 symmetrically suspended below the cabinet cover 210, a plurality of upper partitions 230 slidably arranged on the upper layer of the wall cabinet 220, and a plurality of lower partitions 240 slidably arranged on the middle and lower layers of the wall cabinet 220; the wall cabinet 220 is snap-connected with the independent cavity, and a plurality of isolation layers 221 are horizontally spaced between the two vertical side walls of the wall cabinet 220 so that the pre-prepared dishes placed in the wall cabinet 220, that is, in an independent cavity, will not mix with each other.

[0031] A ventilation cavity 222 is provided through the side of the isolation layer 221, and the interior of the partition 110 is a hollow structure with an opening at the bottom, which is used to guide cold air into the ventilation cavities 222 to quickly freeze the pre-prepared dishes placed on the isolation layer 221; this design allows the cold air to be distributed around the pre-prepared dishes and quickly freeze them. At the same time, the cold air only circulates inside the isolation layer 221 and the partition 110, avoiding ventilation with the internal space of the wall cabinet 220, thereby completely avoiding the contamination of the pre-prepared dishes.

[0032] Furthermore, supporting plates 211 are extended downward from both side ends of the cabinet cover 210, and a step-shaped cabinet side cover 120 is clamped on the top edge of the freezer body 100. A sealing gasket 216 is bonded to the bottom surface of the connection between the upper end of the supporting plate 211 and the side end of the cabinet cover 210, and the sealing gasket 216 is adapted to be clamped with the cabinet side cover 120 to play a sealing role; a plurality of reinforcing ribs 215 are provided at equal intervals on the top surface of the supporting plate 211 to enhance the bending resistance of the supporting plate 211, so that the driving device 300 drives the supporting plate 211 to lift the wall cabinet 220 out of the freezer body 100 to take out and place pre-prepared dishes.

[0033] Specifically, the partition member 110 is composed of a pair of transverse partitions 111 and at least one longitudinal partition 112 that are vertically clamped together. The independent cavity of equal volume is an independent space enclosed by a pair of transverse partitions 111 and the longitudinal partitions 112 and the inner side of the freezer body 100; a plurality of ventilation grooves 113 are provided on the two side walls of the transverse partition 111 and at positions corresponding to the plurality of isolation layers 221. The ventilation grooves 113 are connected to the internal cavity of the transverse partition 111 and are arranged opposite to the ventilation cavity 222; the bottom surface of the wall cabinet 220 is spaced from the bottom of the freezer body 100, so that the cold air generated by the freezer body 100 circulates between the partition member 110 and the plurality of isolation layers 221, and is dispersed around the wall cabinet 220, thereby quickly freezing the pre-prepared dishes in the wall cabinet 220.

[0034] like Figures 8-11 As shown, a reinforcing rod 223 is adapted and connected to the interior of the ventilation cavity 222, and a plurality of ventilation holes 224 are formed through the side wall of the reinforcing rod 223 for guiding the cold air to pass through.

[0035] Furthermore, the cabinet cover 210 is a rectangular frame and a glass plate 213 is installed inside it, and it is made of transparent material so that the dishes inside can be clearly seen. By placing the same pre-prepared dishes in a row in the wall cabinet 220, the dishes can be seen from the outside; the long side of the bottom surface of the cabinet cover 210 is fixedly connected to the hanging rail 217, and the longitudinal section of the hanging rail 217 is wide at the bottom and narrow at the top, thereby forming a limiting structure. The top corners of the upper partition 230 are symmetrically provided with card slots 231, and the card slots 231 are adapted to slide and snap into the hanging rail 217, so that the upper partition 230 is slidably distributed between the upper layers of the wall cabinet 220. The spacing between several upper partitions 230 can be adjusted according to needs to place dishes of different capacities.

[0036] Furthermore, a shaping frame 250 is clamped between the corners of the upper and lower adjacent isolation layers 221, and the upper and lower surfaces of the shaping frame 250 are fixedly connected to the upper and lower isolation layers 221 to increase the deformation resistance of the adjacent isolation layers 221; a guide rail 260 is clamped between the tops of a pair of relatively arranged shaping frames 250, and a slide groove 241 is provided in the middle of the top surface of the lower partition 240 to slide and clamp with the guide rail 260; the longitudinal section of the guide rail 260 is wide at the bottom and narrow at the top, thereby forming a limiting structure, the upper and lower ends of the shaping frame 250 are tripod structures and a slot 251 is provided in the middle of the top surface, and the end of the guide rail 260 is adapted to be plugged into the slot 251; the triangle has stability, thereby further increasing the overall structural stability of the wall cabinet 220 and several isolation layers 221, thereby placing several pre-prepared dishes. By means of the triangular support of the shaping frame 250 and the embedded reinforcing rods 223, the load-bearing and deformation-resistance of the isolation layer 221 is enhanced, so that the structure of the wall cabinet 220 is stabilized when fully loaded with pre-prepared dishes.

[0037] Furthermore, the bottom end of the support plate 211 is bent into a horizontal section and a threaded hole 212 is opened on its top surface. The transmission screw 320 is threadedly connected to the threaded hole 212. The outer edge of the horizontal section of the bottom end of the support plate 211 is rotatably connected to the roller 214 through a pin, which is used to be rolled with the side shell plate of the freezer body 100, so that the support plate 211 can be raised and lowered smoothly without wearing the outer shell surface of the freezer body 100; the support plate 211 is driven to rise and fall by the transmission screw 320, and the wall cabinet 220 and the pre-prepared dishes are lifted up to expose the top of the freezer body 100 for taking and placing the pre-prepared dishes.

[0038] like Figure 5-Figure 7 As shown, the driving device 300 includes a guide cover 310 installed on the side shell plate of the freezer body 100, a transmission screw 320 threadedly connected to the bottom of the support plate 211, and a servo motor 330 for driving the transmission screw 320 to rotate; the support plate 211 and the guide cover 310 are adapted for sliding insertion; the bottom end of the support plate 211 is extended downward to provide an extension plate 312 for covering the servo motor 330 to prevent it from being touched.

[0039] The inner side of the guide cover 310 is fixedly connected with partition plates 311 at equal intervals, and the support plate 211 is adapted to be plugged and slid with two adjacent partition plates 311; the guide cover 310 and a pair of partition plates 311 guide the limit support plate 211 to rise and fall, and the roller 214 rolls against the outer surface of the freezer body 100 to jointly guide the support plate 211 to rise and fall vertically under the transmission action of the transmission screw 320.

[0040] Furthermore, the servo motor 330 is installed on the bottom surface of the outer shell of the freezer body 100, and a control switch is installed on the outer wall of the top of the guide cover 310 to control the forward and reverse drive of the servo motor 330; the upper and lower ends of the transmission screw 320 are provided with a fixing bracket 321, and the two ends of the fixing bracket 321 are plugged into the side wall of the partition plate 311. The transmission screw 320 is positioned to rotate straight through the fixing bracket 321, and the support plate 211 is stably driven to rise and fall vertically.

[0041] When the energy-saving quick-freezing freezer of pre-prepared dishes with adjustable capacity and multiple independent anti-odor storage chambers of the present invention is in use, the servo motors 330 on both sides of a storage cabinet 200 are started to drive it to rise above the top of the freezer main body 100. By automatically adjusting the spacing between the plurality of upper partitions 230 and the spacing between the plurality of lower partitions 240, the different capacities inside the wall cabinet 220 are adjusted to accommodate pre-prepared dishes of different volumes, and pre-prepared dishes of the same type are arranged in a row one above the other so that the dishes can be seen from the outside for taking and placing. The bottom surface of the wall cabinet 220 is spaced apart from the bottom of the freezer main body 100, so that the cold air generated by the freezer main body 100 circulates between the partition member 110 and the plurality of isolation layers 221, and is dispersed around the wall cabinet 220, thereby quickly freezing the pre-prepared dishes in the wall cabinet 220.

[0042] It should be noted that the fixed connection and fixed arrangement of the present invention are achieved using conventional fixing means such as bolt connections or welding. The above embodiments are merely illustrative of the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the content of the present invention and implement it accordingly.
