Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common appliance used to preserve food or other items at low temperatures in life and is widely used in life and industry. A refrigerator can extend the shelf life of food, but as the food is stored for a longer time, it will become corrupt and produce odor and bacteria, thus affecting the safety of other foods in the refrigerator. In addition, there is also the problem of odor mixing between the refrigerator and the freezer for air-cooled refrigerators.

[0003] In the related art, the refrigeration and preservation function of refrigerators on the market is generally achieved by installing a catalyst component in the cold storage room. The wind in the cold storage room circulates through the holes on the surface of the catalyst component to achieve the preservation function. The catalyst component usually includes a catalyst block and a catalyst block mounting structure for mounting the catalyst block. The catalyst block is commonly used in refrigerators, freezers, wine cabinets and other similar equipment, and has antibacterial, purification, and deodorization functions. The catalyst block is usually set in the door body, the back of the freezer drawer, or the upper injection molded air duct rear cover. It is necessary to set a separate catalyst block mounting component, such as a catalyst block base and a catalyst block cover, as well as other auxiliary connection structures to install and fix the catalyst block.

[0050] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common appliance used to preserve food or other items at low temperatures in life and is widely used in life and industry. A refrigerator can extend the shelf life of food, but as the food is stored for a longer time, it will become corrupt and produce odor and bacteria, thus affecting the safety of other foods in the refrigerator. In addition, there is also the problem of odor mixing between the refrigerator and the freezer for air-cooled refrigerators.

[0051] In the related art, the refrigeration and preservation function of refrigerators on the market is generally achieved by installing a catalyst component in the cold storage room. The wind in the cold storage room circulates through the holes on the surface of the catalyst component to achieve the preservation function. The catalyst component usually includes a catalyst block and a catalyst block mounting structure for mounting the catalyst block. The catalyst block is commonly used in refrigerators, freezers, wine cabinets and other similar equipment, and has antibacterial, purification, and deodorization functions. The catalyst block is usually set in the door body, the back of the freezer drawer, or the upper injection molded air duct rear cover. It is necessary to set a separate catalyst block mounting component, such as a catalyst block base and a catalyst block cover, as well as other auxiliary connection structures to install and fix the catalyst block.

[0052] However, the above catalyst block installation assembly has a complex structure and a high production cost.

[0053] Based on this, the present application provides a refrigerator. The related parts for installing the catalyst block inside the refrigerator have a simple structure and are convenient to assemble, which can effectively reduce the production cost. The refrigerator provided by the present application will be described in detail below with reference to the accompanying drawings of the present application.

[0054] Figure 1 FIG. 1 shows one of the overall structural schematic diagrams of the refrigerator provided by the embodiment of the present application. Referring to Figure 1 , the refrigerator 1 may include a cabinet 10. The cabinet 10 may include an outer shell 11 and an inner liner 12 disposed inside the outer shell 11. A refrigeration chamber 13 is formed inside the inner liner 12.

[0055] It should be noted that the refrigeration chamber 13 may be a refrigerating chamber, a variable temperature chamber or a freezing chamber. The temperature of the refrigerating chamber is generally between 2°C and 8°C, which can keep food in a refrigerated state; the temperature of the freezing chamber is generally between -14°C and -26°C, which can keep food in a frozen state; the adjustable temperature range of the variable temperature chamber is generally between 5°C and -7°C, or can be directly adjusted to -18°C for use as a freezing chamber.

[0056] Continuing to refer to Figure 1 , in some embodiments of the present application, an opening 14 communicating with the refrigeration chamber 13 is further provided on the cabinet 10, and a plurality of storage drawers 15 arranged along the height direction of the cabinet 10 are provided in the refrigeration chamber 13.

[0057] In this way, users can place different categories of items in different storage drawers 15 through the above-mentioned opening 14 according to their own usage needs, or take out the items from the storage drawers 15 through the opening 14.

[0058] Figure 2 FIG. 2 shows another overall structural schematic diagram of the refrigerator provided by the embodiment of the present application. Figure 3 FIG. 3 shows Figure 2 a cross-sectional structural schematic diagram at position A-A. Referring to Figure 2 and Figure 3 , the refrigerator 1 may further include a plastic suction air duct assembly 20. The plastic suction air duct assembly 20 is spaced from the inner wall surface of the inner liner 12 to define an air flow channel 21, and the air flow channel 21 communicates with the refrigeration chamber 13.

[0059] In this way, the air flow inside the refrigerator 1 can circulate in the direction indicated by the arrow in Figure 3 . For the specific structure of the plastic suction air duct assembly 20 and the specific air flow mode, please refer to Figure 4 and Figure 5 and the relevant descriptions below for further understanding.

[0060] Figure 4 FIG. 4 shows a schematic diagram of the position of the plastic suction air duct assembly provided by the embodiment of the present application inside the cabinet.Figure 5 Shows Figure 4 Enlarged structural diagram at position B, see Figure 3 、 Figure 4 and Figure 5 , the blister air duct assembly 20 may include a first blister plate 22, the first blister plate 22 and the box 12 form a first air duct 211, the first air duct 211 has a return air port 212, the return air port 212 connects the first air duct 211 and the refrigeration chamber 13, and the first air duct 211 is at least part of the air flow channel 21.

[0061] In this way, after the airflow in the refrigerator 1 flows in the refrigeration chamber 13, it can enter the first air duct 211 in the air flow channel 21 through the return air port 212.

[0062] Figure 6 shows one of the structural schematic diagrams of the blister air duct assembly provided in the embodiment of the present application, Figure 7 shows the second structural schematic diagram of the blister air duct assembly provided in the embodiment of the present application, in conjunction with Figure 6 and Figure 7 The first blister plate 22 may include a plate body 221, at least a portion of which faces away from the box 12 (eg, Figure 3 As shown in the figure, one side of the plate body 221 is raised to form a blister cover 222, and at least another part of the plate body 221 forms a blister box 223, which can be connected with the blister cover 222 to form a receiving cavity 224. The blister box 223 is provided with a first vent hole 2231, which connects the receiving cavity 224 and the first air duct 211.

[0063] It can be understood that the blister cover 222 and the blister box 223 for installing the catalyst block 225 provided in the present application can be blistered together with the first blister plate 22, and then punched and formed by a punching mold, that is, the blister cover 222 and the blister box 223 are integrated on the first blister plate 22, and there is no need to separately set up the catalyst block 225 base, the catalyst block 225 cover and other connecting structures to install the catalyst block 225.

[0064] In this way, on the one hand, the use of materials is reduced, so that the production cost of the refrigerator 1 can be reduced. On the other hand, since the installation of the catalyst block 225 can be directly installed by the air duct parts factory and then supplied as a complete set, the assembly process of the refrigerator 1 is simplified, the pre-installation of the catalyst block 225 is reduced, and the production cycle is improved, which is conducive to improving the production efficiency of the product.

[0065] ​​In addition, the first ventilation hole 2231 formed on the plastic suction box 223 of the present application can communicate the accommodation cavity 224 and the first air duct 211. In this way, when the air flow in the refrigerator 1 flows in the refrigeration chamber 13 and then enters the first air duct 211 in the air flow passage 21 through the air return port 212, the air flow can enter the accommodation cavity 224 through the first ventilation hole 2231 and carry out a catalytic reaction with the catalyst block 225 in the accommodation cavity 224, thereby filtering out impurities such as bacteria, dust, and carbon deposits in the air flow and realizing functions such as antibacterial, purification, and odor removal.

[0066] Figure 8 shows a schematic structural diagram of the plastic suction box provided by the embodiment of the present application. Refer to Figure 8 , the first ventilation hole 2231 can be set to one, or can be set in the form of multiple spaced arrangements as shown in Figure 8 . In this way, it can promote the sufficient reaction of the air flow entering the first air duct 211 with the catalyst block 225, thereby achieving better antibacterial, purification, and odor removal effects. In addition, the specific position of the first ventilation hole 2231 can be set on the four side wall surfaces 2232 of the plastic suction box 223, or can be set on the bottom wall surface 2233 of the plastic suction box 223 as shown in Figure 8 . The specific shape of the first ventilation hole 2231 can be a waist-shaped hole, a square hole, a round hole, etc., as long as it can communicate the accommodation cavity 224 and the first air duct 211, and no limitation is made here.

[0067] Figure 9 shows a schematic installation structure diagram of the catalyst block in the plastic suction box provided by the embodiment of the present application. Referring to Figure 6 , Figure 7 and Figure 9 , during the assembly process, the catalyst block 225 can be first placed in the plastic suction box 223, and then the plastic suction box 223 is connected to the plastic suction cover 222, so that the catalyst block 225 can be stably limited in the accommodation cavity 224 formed by the plastic suction box 223 and the plastic suction cover 222.

[0068] Furthermore, the outer peripheral surface of the catalyst block 225 can also be wrapped with a shock-absorbing member such as a sponge pad, a rubber pad, or a foam pad, so as to prevent the catalyst block 225 from colliding with the plastic suction box 223 or the plastic suction cover 222 due to the vibration generated during the operation of the refrigerator 1, resulting in the fragmentation and failure of the catalyst block 225.

[0069] It should also be noted that the catalyst block 225 can be a metal catalyst block 225, a metal oxide catalyst block 225, or an iron-based catalyst block 225, etc. The catalyst can be loaded on a porous skeleton such as honeycomb ceramics or metal meshes to increase the contact area between the catalyst and the air flow.

[0070] Figure 10 shows a schematic structural diagram of the plastic suction cover provided by the embodiment of the present application.Figure 11 shows Figure 10 a schematic enlarged view at position C. Referring in combination to Figure 8 , Figure 10 and Figure 11 , in some embodiments of the present application, the blister cover 222 and the blister box 223 can be configured to be rotatably connected, and at least one outer side wall of the blister cover 222 is provided with a first clamping rib 2221, and at least one inner side wall of the blister box 223 is provided with a second clamping rib 2234.

[0071] In this way, by simply rotating the blister box 223 clockwise towards the blister cover 222 until the first clamping rib 2221 can abut against the second clamping rib 2234, the blister cover 222 and the blister box 223 can be quickly clamped together to form a receiving cavity 224 for installing the catalyst block 225.

[0072] In other possible structural designs of the present application, the blister box 223 and the blister cover 222 can also be connected by a threaded connection. Exemplarily, internal threads can be provided on the blister box 223 and the blister cover 222, and screws or bolts can be passed through the internal threads to connect the blister box 223 and the blister cover 222.

[0073] Figure 12 shows the internal air flow circulation path diagram of the refrigerator provided by the embodiments of the present application. Referring in combination to Figure 8 , Figure 11 and Figure 12 , in some embodiments of the present application, the blister cover 222 is provided with a second ventilation hole 2222, and the second ventilation hole 2222 communicates the receiving cavity 224 and the refrigerating chamber 13.

[0074] It can be understood that the second ventilation hole 2222 on the blister cover 222 that communicates the receiving cavity 224 and the refrigerating chamber 13 can indirectly communicate the first air duct 211 and the refrigerating chamber 13, so that a part of the air flow that enters the receiving cavity 224 from the first air duct 211 through the first ventilation hole 2231 reacts catalytically with the catalyst block 225 and then enters the refrigerating chamber 13 again. That is to say, there are the following two paths of air flow circulation in the refrigerator 1 of the present application:

[0075] The first path, the flow path of the air flow is successively the refrigerating chamber 13 - the air return opening 212 - the first air duct 211 - the catalyst block 225 - the second air duct 213 - the refrigerating chamber 13; the second path, the flow path of the air flow is successively the refrigerating chamber 13 - the air return opening 212 - the first air duct 211 - the first ventilation hole 2231 - the catalyst block 225 - the second ventilation hole 2222 - the refrigerating chamber 13.

[0076] Thus, since the traditional structure only has the air flow circulation mode of the above-mentioned first path, while the present application constitutes a double air flow circulation mode, and compared with the first path, the route of the second path is shorter and the number of circulations within the same time period is more. Therefore, during the circulating flow of the air flow, it can carry out a more sufficient catalytic reaction with the catalyst block 225, thereby further improving the antibacterial, purification, odor removal and other effects of the refrigerator 1.

[0077] Continue to refer to Figure 8 、 Figure 9 and Figure 11 In some embodiments of the present application, the plastic suction cover 222 may include a first clamping surface 2223, and the second ventilation hole 2222 is provided on the first clamping surface 2223. The plastic suction box 223 may include a second clamping surface 2235 (i.e., the bottom wall surface 2233), and the first ventilation hole 2231 is provided on the second clamping surface 2235. When the plastic suction cover 222 is snap-connected to the plastic suction box 223, the first clamping surface 2223 abuts against one side of the catalyst block 225, and the second clamping surface 2235 abuts against the other side of the catalyst block 225.

[0078] Thus, by setting the position of the first ventilation hole 2231 on the second clamping surface 2235 and the position of the second ventilation hole 2222 on the first clamping surface 2223, after the first clamping surface 2223 and the second clamping surface 2235 stably clamp the catalyst block 225, it can promote as much air flow as possible in the first air duct 211 to circulate in the way of the second path, thereby increasing the air flow circulation and filtration times within the same time period.

[0079] Figure 13 Fig. shows the third structural schematic diagram of the plastic suction air duct assembly provided by the embodiment of the present application. In combination with referring to Figure 11 、 Figure 12 and Figure 13 In some embodiments of the present application, the refrigerator 1 may further include a heat exchanger 30, and the plastic suction air duct assembly 20 may further include a second plastic suction plate 23. The second plastic suction plate 23 is connected to one end of the first plastic suction plate 22 away from the catalyst block 225. The second plastic suction plate 23 and the cabinet liner 12 form a second air duct 213. The second air duct 213 is communicated with the first air duct 211 to form an air flow channel 21. Among them, the heat exchanger 30 is arranged in the second air duct 213, and the catalyst block 225 is located at the bottom of the heat exchanger 30.

[0080] It is understandable that due to the circulation of airflow in the refrigerator 1, the catalyst block 225 is exposed to humid air for a long time, which makes the catalyst block 225 easy to break and fall off. In the traditional structural design, the catalyst block 225 is usually arranged above the heat exchanger 30. After the catalyst block 225 falls off, the debris falls on the heat exchanger 30 and causes corrosion of the heat exchanger 30. In the structural scheme of the present application, the blister box 223, the blister cover 222 and the catalyst block 225 are arranged in the first air duct 211 at the bottom, and the heat exchanger 30 is arranged in the second air duct 213 at the top. In this way, even if the debris of the catalyst block 225 falls off, it will not fall on the heat exchanger 30, thereby effectively avoiding the corrosion of the heat exchanger 30.

[0081] Figure 14 Shows the third schematic diagram of the overall structure of the refrigerator provided in the embodiment of the present application, Figure 15 Shows Figure 14 Enlarged structural diagram at position D, see Figure 13 、 Figure 14 and Figure 15 , in some embodiments of the present application, the refrigerator 1 may further include a water receiving tray 40, the water receiving tray 40 is located at the bottom of the heat exchanger 30, the second blister plate 23 includes a plurality of guide members 231, guide grooves 232 and guide holes 233, and the plurality of guide members 231 are arranged at intervals and face away from the box 12 (such as Figure 12 As shown in FIG. 1 , the guide groove 232 is located at the bottom of the plurality of guide members 231 , and the guide hole 233 connects the guide groove 232 and the water receiving tray 40 .

[0082] It can be understood that the multiple guide pieces 231 formed on the second blister plate 23 have two effects. First, the condensation generated in the refrigeration chamber 13 can flow downward along the guide pieces 231, drip and gather in the guide groove 232, and discharge the liquid into the water receiving tray 40 through the guide holes 233; second, the guide pieces 231 on the second blister plate 23 can also serve as reinforcing ribs, so that the second blister plate 23 has better structural strength.

[0083] Figure 16 shows a fourth structural schematic diagram of the blister air duct assembly 20 provided in an embodiment of the present application, see Figure 16 , in some embodiments of the present application, the guide groove 232 may include a first guide surface 2321 and a second guide surface 2322.

The second guide surface 2322 and the first guide surface 2321 are arranged opposite to each other, and along the first direction, the second guide surface 2322 is tilted toward the direction away from the first blister plate 22. The guide hole 233 is arranged at the boundary line between the first guide surface 2321 and the second guide surface 2322.

[0084] That is to say, the first diversion surface 2321 and the second diversion surface 2322 are arranged to be relatively inclined. In this way, it is beneficial to promote the liquid dripping on the first diversion surface 2321 and the second diversion surface 2322 along the drainage member 231 to be discharged to the drainage holes in time, so as to keep the refrigeration chamber 13 dry.

[0085] Continue to refer to Figure 16 , in some embodiments of the present application, similar to the second plastic suction plate 23, the first plastic suction plate 22 may also include a plurality of drainage members 226. The plurality of drainage members 226 are arranged at intervals and protrude toward the side close to the inner container 12, so as to enhance the structure of the first plastic suction plate 22 and the effect of drainage.

[0086] In summary, the refrigerator 1 provided by the present application mainly has the following technical effects:

[0087] (1) In the present application, the plastic suction cover 222 and the plastic suction box 223 are integrated on the first plastic suction plate 22, which not only reduces the use of materials, enables the production cost of the refrigerator 1 to be reduced, but also simplifies the assembly process of the refrigerator 1, improves the production beat, and thus is beneficial to improving the production efficiency of the product;

[0088] (2) In the present application, the air flow inside the refrigerator 1 is designed to have a dual-cycle mode, and compared with the first path, the second path is shorter and the number of cycles in the same time period is more. Therefore, the air flow can undergo a more sufficient catalytic reaction with the catalyst block 225 during the cyclic flow process, thereby further enhancing the antibacterial, purification, odor removal and other effects of the refrigerator 1;

[0089] (3) In the present application, the plastic suction box 223, the plastic suction cover 222 and the catalyst block 225 are arranged in the lower first air duct 211, and the heat exchanger 30 is arranged in the upper second air duct 213. So that the debris falling off the catalyst block 225 will not fall on the heat exchanger 30, thus effectively avoiding the corrosion phenomenon of the heat exchanger 30.
