Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a walk-in refrigerator. Background Art

[0002] At present, refrigerators are relatively common household appliances in people's lives. However, with the improvement of living standards, ordinary refrigerators can no longer meet the needs of some users. Combining past household data, it is found that some wealthy people often need multiple large refrigerators at present. Iterating only on the existing single large-capacity refrigerator cannot meet the user's needs, and the product needs to break through the constraints of the existing capacity.

[0003] In related technologies, some families have begun to install cold storages indoors and assemble the entire room into a cold storage room. However, this storage method occupies too much space and is often only applicable to high-end residences such as villas. Moreover, when accessing items, users need to enter an environment that has been at a low temperature for a long time, resulting in the users being in a low-temperature environment and affecting the comfort of the users.

[0004] Therefore, it can be seen that how to meet the user's demand for the refrigerator capacity, provide the user with a walk-in experience, effectively control costs, and maintain the comfort of the user has become a technical problem that needs to be solved urgently by those skilled in the art.

[0005] It should be noted that the information disclosed in the above background art section is only used to strengthen the understanding of the background of the present application. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0006] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below.

[0007] The embodiments of the present disclosure provide a walk-in refrigerator to solve the technical problem that when accessing items, users need to enter an environment that has been at a low temperature for a long time, resulting in the users being in a low-temperature environment and affecting the comfort of the users.

[0008] In some embodiments, the walk-in refrigerator includes: a main cabinet and a first side cabinet. In the middle area of the front side of the main cabinet, a first storage area is provided, and pull-out areas are provided on both sides of the first storage area; there are two first side cabinets, which are respectively vertically arranged in the pull-out areas on both sides of the first storage area in a pull-out manner, and jointly define a semi-open access room with the main cabinet when they are pulled out.

[0009] The walk-in refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects:

[0010] Two pull-out first side cabinets are provided on the main cabinet. After the two first side cabinets are pulled out, a semi-enclosed rectangular space can be formed with the main cabinet. This rectangular space allows users to walk in, forming a storage and retrieval area for users to access items on the main cabinet and the first side cabinets. The main cabinet and the two first side cabinets are used to store items simultaneously, increasing the refrigerator volume. Moreover, the main cabinet and the two first side cabinets surround the user, providing a walk-in experience. Among them, the second pair of cabinets is only pulled out when the user needs to access or store items. The temperature in the formed storage and retrieval area is close to room temperature, without the feeling of overcooling, maintaining the comfort of the ambient temperature while the user enjoys the walk-in experience and not reducing the overall user experience.

[0041] Combined with Figure 1-6 As shown, the embodiments of the present disclosure provide a walk-in refrigerator, including: a main cabinet 100 and a first side cabinet 200. In the middle area of the front side of the main cabinet 100, there is a first storage area 101, and on both sides of the first storage area 101, there are pull-out areas 102; there are two first side cabinets 200, and they are respectively vertically arranged in the pull-out areas 102 on both sides of the first storage area 101 in a pull-out manner, and jointly define a semi-open access room 300 with the main cabinet 100 when they are pulled out.

[0042] Using the walk-in refrigerator provided by the embodiments of the present disclosure, two pull-out first side cabinets 200 are arranged on the main cabinet 100. After the two first side cabinets 200 are pulled out, a semi-enclosed rectangular space can be formed with the main cabinet 100. This rectangular space allows users to walk in, forming a storage and retrieval area 300 for users to store and retrieve items on the main cabinet 100 and the first side cabinets 200. By using the main cabinet 100 and the two first side cabinets 200 to store items simultaneously, the volume of the refrigerator is increased. Moreover, the main cabinet 100 and the first side cabinets 200 surround the user, providing the user with a walk-in experience. Among them, the first side cabinet 200 is only pulled out when the user needs to store and retrieve items. The temperature in the formed storage and retrieval area 300 is close to room temperature and there is no feeling of excessive cold, maintaining the comfort of the ambient temperature while the user enjoys the walk-in experience and not reducing it, improving the overall user experience.

[0043] Optionally, the walk-in refrigerator further includes: a second side cabinet 400. The second side cabinet 400 is slidably connected to the first side cabinet 200, and the sliding direction is the same as the sliding direction of the first side cabinet 200 relative to the main cabinet 100. In this way, on the basis of the first side cabinet 200, a pull-out second side cabinet 400 is added, further increasing the hierarchical division of the storage space, improving the convenience for users to store and retrieve items classified, and increasing the overall pulling distance of the first side cabinet 200 and the second side cabinet 400 relative to the main cabinet 100, enhancing the user's walk-in experience. At the same time, when maintaining a relatively large pulling distance relative to the main cabinet 100 as a whole, the thickness of the main cabinet 100 can be effectively reduced, avoiding the situation that it is difficult to store and retrieve items in the first storage area 101 on the main cabinet 100 due to the too large thickness of the main cabinet 100, optimizing the rationality of the layout of each storage space, and improving the convenience of user use.

[0044] Optionally, the first side cabinet 200 includes: a second storage area 202 and a pull-out bin 203. The second storage area 202 faces the storage and retrieval area 300; the pull-out bin 203 is arranged on the side of the second storage area 202 opposite to the storage and retrieval area 300, and the second side cabinet 400 is slidably arranged in the pull-out bin 203. In this way, both the second storage area 202 and the first storage area 101 can face the storage and retrieval area 300, facilitating users to store and retrieve items more conveniently when walking into the storage and retrieval area 300. And a pull-out bin 203 is arranged on the first side cabinet 200, enabling the second side cabinet 400 to be pulled out in the pull-out bin 203. When the second side cabinet 400 is located inside the pull-out bin 203, its closed state can be maintained, reducing unnecessary cold leakage. And the position of the pull-out bin 203 is arranged on the side of the second storage area 202 opposite to the storage and retrieval area 300, which can avoid blocking the second storage area 202.

[0045] Optionally, the second storage area 202 communicates with the drawer bin 203 through the first air hole 204. In this way, cold air can enter the second storage area 202 from the drawer bin 203 through the first air hole 204 to supply cold to the second storage area 202, and the low temperature in the second side box 400 can still be maintained after the first side box 200 is pulled out.

[0046] Optionally, a third storage area 403 with the same orientation as the second storage area 202 is provided on the second side box 400. In this way, the third storage area 403 on the second box 120 has the same orientation as the second storage area 202, which is convenient for users to access items in it in the access room 300, and the first storage area 101, the second storage area 202, and the third storage area 403 can all face the access room 300 together, improving the display effect in the access room 300.

[0047] Optionally, the third storage area 403 communicates with the drawer bin 203 through the second air hole 404. In this way, the cold air in the drawer bin 203 can enter the third storage area 403 through the second air hole 404. Similarly, when both the first side box 200 and the second side box 400 are pulled out, the low temperature environment in the third storage area 403 can be maintained.

[0048] Optionally, a connecting air duct is provided between the main box 100 and the first side box 200. In this way, the main box 100 sends cold air into the first side box 200 through the connecting air duct to maintain the refrigerated environment in the first side box 200 and improve the storage effect.

[0049] Optionally, the main box 100 communicates with the drawer bin 203 of the first side box 200 through the connecting air duct. In this way, cold quantity is provided to the drawer bin 203 through the main box 10, and then cold can be supplied to the second storage area 202 and the third storage area 403 through the drawer bin 203. When the first side box 200 and the second side box 400 are pulled out, the low temperature environments on the first side box 200 and the second side box 400 can still be maintained.

[0050] Optionally, a heat insulation layer is provided on one side of the drawer bin 203 facing away from the opening direction of the second storage area 202. In this way, the heat insulation effect of the drawer bin 203 can be improved, the leakage of energy in the drawer bin 203 can be reduced, it is more energy-saving, and the low temperature environments in the second storage area 202 and the third storage area 403 can be better maintained.

[0051] Optionally, the height of the first side box body 200 is greater than or equal to 95% of the height of the main box body 100 and less than or equal to the height of the main box body 100. In this way, when the first box body 110 is slidably arranged in the main box body 100, the height of the first box body 110 is maintained close to the height of the main box body 100, so as to form a more regular semi-closed space, make full use of the space, enable the first side box body 200 to better cooperate with the main box body 100, and enable the user to have the feeling of stepping into an independent space, providing a better stepping experience for the user.

[0052] Optionally, the first storage area 101 includes: a freezing area 103, a vacuum area 104 and an operation area 105. The operation area 105 is arranged between the freezing area 103 and the vacuum area 104, and the three are arranged vertically. In this way, the first storage area 101 on the main box body 100 is mainly used to store some items that need to be frozen at low temperature and stored in vacuum, so as to store the items more refinedly. At the same time, an operation area 105 is arranged in the middle area, which can complement the cabinets in the kitchen, making it more convenient and comfortable for the user to operate the materials in the operation area 105.

[0053] Optionally, a first sliding door 106 is provided at the mouth of the vacuum area 104, and the first sliding door 106 can be slid upward or downward to open. In this way, setting the first sliding door 106 of the vacuum area 104 to slide up and down can avoid interference with the first side box body 200 in the left-right opening mode and affect the use experience.

[0054] Optionally, no door body is provided on the operation area 105, or a second sliding door body 107 is provided, and the second sliding door body 107 can also be slid upward or downward to open. In this way, interference with the first side box body 200 in the left-right opening direction can also be avoided.

[0055] Optionally, the length of the pull-out bin 203 in the longitudinal height direction is less than the length of the second storage area 202 in the longitudinal height direction, and the depth of a part of the second storage area 202 can extend to the side surface of the pull-out bin 203 and the side surface facing away from the second storage area 202 and be flush with this side surface. In this way, the second storage area 202 can retain some storage spaces with a larger depth, which is convenient for storing some large-volume items.

[0056] Optionally, the upper end of the pull-out bin 203 is flush with the upper end of the second storage area 202, and the lower end of the pull-out bin 203 is higher than the lower end of the second storage area 202. In this way, the part with a larger depth on the second storage area 202 can be arranged at the bottom of the entire second storage area 202, and larger items can be stored at the bottom of the second storage area 202 to improve the storage stability.

[0057] Optionally, the first storage area 101, the second storage area 202, and the third storage area 403 are all provided with independent door bodies. In this way, when the first side box body 200 and the second side box body 400 are pulled out, the independent door bodies can keep each storage area closed when not in use, reducing the leakage of cold air and better maintaining the refrigerated storage environment.

[0058] Optionally, a detachable storage frame is provided on the second storage area 202 or the third storage area 403, and a handle is provided on the side of the storage frame. In this way, the storage frame can be directly removed from the second storage area 202 or the third storage area 403, facilitating the access of items therein.

[0059] Optionally, pull-out moving wheels 205 are provided on the lower side of the first side box body 200. In this way, since the weight of the items stored in the first side box body 200 is relatively high, the pull-out moving wheels 205 provided on its lower side can provide effective support for the first side box body 200, keeping the first side box body 200 able to be smoothly pulled out, relieving the force between the main box body 100 and the first side box body 200, and improving the overall stability.

[0060] Combined Figure 7-13 As shown, in some alternative embodiments, the main box body 100 includes: a first box body 110 and a second box body 120. A refrigeration device 111 and a first splicing air duct 112 connected to the refrigeration device 111 are arranged inside the first box body 110, and a switchable first splicing port 113 is reserved on the first splicing air duct 112; one or more second box bodies 120 are provided, and a second splicing air duct 121 is arranged inside, and the second splicing air duct 121 is provided with a switchable second splicing port 122 and a third splicing port 123, wherein the second splicing port 122 can be adapted and spliced with the first splicing port 113, and the third splicing port 123 is used for being adapted and spliced with the second splicing port 122 of other box bodies when multiple second box bodies 120 are provided. In this way, a refrigeration device 111 is arranged inside the first box body 110 and is connected to the first splicing air duct 112, and a second splicing air duct 121 is arranged inside the second box body 120. When the first box body 110 and the second box body 120 are combined, the first splicing port 113 on the first splicing air duct 112 and the second splicing port 122 on the second splicing air duct 121 can be spliced and combined with each other, so that the two box bodies can share the refrigeration device 111, thereby reducing the overall cost. Compared with multiple independent refrigerators, the combined refrigerator in this solution has stronger linkage between the combined box bodies, and can effectively improve the user experience.

[0061] Optionally, splicing surfaces 130 are provided on both the first box body 110 and the second box body 120. The splicing surfaces 130 of different box bodies can be adapted and spliced with each other. Moreover, the first splicing interface 113, the second splicing interface 122, and the third splicing interface 123 are all installed on the splicing surface 130. In this way, by providing the splicing surfaces 130 on both the first box body 110 and the second box body 120, it is convenient to splice the two box bodies. And since the first splicing interface 113, the second splicing interface 122, and the third splicing interface 123 are all installed on the splicing surface 130, when the splicing surfaces 130 of the first box body 110 and the second box body 120 are spliced with each other, it is convenient for the splicing interfaces to be connected to each other, enabling the first box body 110 and the second box body 120 to better form an integral whole, and making the assembled box bodies have better integrity.

[0062] Optionally, two splicing surfaces 130 are provided on the first box body 110, which are respectively the left and right side surfaces thereof. And two first splicing interfaces 113 are provided on the first splicing air duct 112, which are respectively oriented towards the two splicing surfaces 130. In this way, the left and right sides of the first box body 110 can be spliced with the second box body 120, improving the applicability of the first box body 110.

[0063] It can be understood that the second box body 120 can also be provided with two splicing surfaces 130 or can also be provided with only one splicing surface 130. In the case of providing two splicing surfaces 130, one can be spliced with the first box body 110, and the other can be spliced with other second box bodies 120. In the case of providing only one splicing surface 130, it is only used for splicing with the first box body 110.

[0064] Optionally, the splicing surface 130 is a single-layer injection molding plate or a single-layer sheet metal layer. In this way, since the splicing surfaces 130 between different box bodies can be spliced with each other and the splicing surfaces 130 will not be directly exposed after splicing, the requirement for the heat preservation effect is not high. By using a single-layer injection molding plate or a single-layer sheet metal layer, the cost can be effectively reduced, and the thickness of the splicing surface 130 can be effectively reduced, thereby reducing the width of the overall combined refrigerator after splicing and reducing the space occupation.

[0065] Optionally, the combined refrigerator further includes a heat preservation cover plate 140, and the heat preservation cover plate 140 can be adapted to cover the splicing surface 130. In this way, in the case where some splicing surfaces 130 are not spliced with other splicing surfaces 130, the heat preservation cover plate 140 can cover this part of the splicing surface 130 to improve the heat preservation effect of this splicing surface 130.

[0066] Optionally, fixing positions 150 are provided on both the left and right sides of the gap formed after the splicing surfaces 130 of the first box body 110 and the second box body 120 are spliced together, and the two fixing positions 150 are clamped by a fixing member 151. In this way, the two can be better fixed from the side of the splicing surface 130 through the fixing member 151, ensuring the splicing stability while improving the convenience of splicing and combining the two.

[0067] In some alternative embodiments, mounting grooves 160 are provided on the lower sides of the first box body 110 and the second box body 120. Moving wheels 161 are provided in the mounting grooves 160, and the fixing positions 150 are arranged in the mounting grooves 160. The fixing member 151 includes a connecting portion and a clamping portion. The clamping portions are vertically arranged at both ends of the connecting portion and can be clamped on the side walls of the mounting grooves 160, so that the connecting portion is attached to the lower side surfaces of the first box body 110 and the second box body 120. In this way, the moving wheels 161 arranged in the mounting grooves 160 can effectively reduce the height of the first box body 110 and the second box body 120 from the bottom of the moving wheels 161, avoiding too large a gap on the lower side of the refrigerator. At the same time, by using the mounting grooves 160 as the fixing positions 150 for connecting the first box body 110 and the second box body 120, the structure of the mounting grooves 160 can be fully utilized, and there is no need to additionally provide fixing positions 150, simplifying the structure at the bottom of the first box body 110 and the second box body 120.

[0068] Optionally, connecting plates 170 are further provided on the upper side and the rear side of the joint formed between the first box body 110 and the second box body 120. The connecting plates 170 cover part of the joint and are respectively fixedly connected to the first box body 110 and the second box body 120 by screws. In this way, the first box body 110 and the second box body 120 can be more stably connected through the connecting plates 170, improving the connection stability between the two.

[0069] In some other alternative embodiments, the fixing positions 150 are raised ribs along the sides of the first box body 110 and the second box body 120 close to the splicing surface 130, and the fixing positions 150 provided on the first box body 110 and the fixing positions 150 provided on the second box body 120 are respectively provided with card slots with opposite openings, and the fixing member 151 is a U-shaped clamp that can be simultaneously inserted into the two card slots with opposite openings. In this way, the two are fixed by directly clamping the U-shaped clamp on the raised ribs on the sides of the two spliced box bodies, with a good fixing effect, more convenient fixing, and a faster disassembly and assembly process.

In this way, the user can directly operate the locking control assembly 500 on the front side of the door panel 402, and control the opening and closing of the first locking structure 501 and the second locking structure 502 through the locking control assembly 500, so that the first side box body 200 and the second side box body 400 can be pulled out separately or both can be pulled out, facilitating the user to select a suitable area for storage and retrieval according to different items and improving the convenience of user use.

[0122] It can be understood that the first locking structure 501 and the second locking structure 502 can be a mechanical locking structure or an electromagnetic locking structure. Preferably, the electromagnetic locking structure is adopted, and both the mechanical locking structure and the electromagnetic locking structure are well-known technical means in the art and will not be elaborated here.

[0123] Optionally, the locking control component 500 includes a first locking key 503 and a second locking key 504. When it is detected that the user triggers the first locking key 503, the first locking structure 501 is controlled to lock and the second locking structure 502 is controlled to unlock. When it is detected that the user triggers the second locking key 504, the second locking structure 502 is controlled to lock and the first locking structure 501 is controlled to unlock. When it is not detected that the user triggers the first locking key 503 and the second locking key 504, the first locking structure 501 is controlled to be closed, or one of the first locking structure 501 and the second locking structure 502 is controlled to lock and the other is controlled to unlock. When it is determined that one of the first side box body 200 and the second side box body 400 is completely pulled out, the first locking structure 501 or the second locking structure 502 in the other locked state is controlled to unlock. In this way, by triggering the first locking key 503 or the second locking key 504, the pulling out of the first side box body 200 and the second side box body 400 can be controlled more directly, making the use more convenient and intuitive.

[0124] Optionally, the first slide rail 201 and the second slide rail 401 are electric slide rails, and the electric slide rails are connected to a slide rail controller, and the slide rail controller is connected to the locking control component 500. When it is determined that the user triggers the first locking key 503 or the second locking key 504, the slide rail corresponding to the first locking structure 501 or the second locking structure 502 in the open state is controlled to slide; when the user does not trigger the first locking key 503 and the second locking key 504, when it is determined that the user pulls the first side box body 200 and the second side box body 400, the first slide rail 201 and the second slide rail 401 are synchronously controlled to start sliding. In this way, when the user triggers the first locking key 503 or the second locking key 504, the first slide rail 201 or the second slide rail 401 can be directly controlled to pull out the first side box body 200 or the second side box body 400, improving the convenience of user use.

[0125] It can be understood that the slide rail control component is also connected to an opening key. When the user directly triggers the opening key, the first slide rail 201 and the second slide rail 401 are synchronously controlled to start sliding.
