Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The refrigeration device of the present invention may be implemented as a domestic refrigerator, freezer or wine chest or the like. The present invention will be specifically described below by taking an example in which a refrigeration apparatus is implemented as a refrigerator.
Fig. 1 is a schematic perspective view of a refrigerator body according to an embodiment of the present invention, and fig. 2 is a longitudinal sectional view of fig. 1. Referring to fig. 1 and 2, a refrigerator body 10 includes a storage chamber 2 defined by an inner container 1, articles to be cooled may be stored in the storage chamber 2 having a certain storage temperature, and the storage chamber 2 may be closed by a door (not shown). The cold air circulating inside the storage chamber 2 constantly cools the storage chamber 2 to maintain the storage chamber 2 at a preset storage temperature. The specific air path circulation is probably as follows: after being cooled by the evaporator 31, the air enters the air supply duct 33 under the action of the blower 32, and then enters the storage chamber 2 from an air outlet (not shown) at the side of the duct cover 4. The cold air cools the storage chamber 2 and absorbs heat, and then returns to the evaporator chamber 36 through the air return opening 35 at the bottom of the storage chamber 2, and is re-cooled by the evaporator 31, thereby entering the next air path cycle.
The air supply duct 33 is defined by a duct assembly in the storage chamber 2, specifically, may be defined by a duct cover plate 4 and another duct rear cover plate (not shown) attached to the back wall of the inner container 1, or may be defined by the duct cover plate 4 and the back wall of the inner container 1. The evaporator compartment 36 can be generally defined by a front cover 37 and the back wall of the tank 1. The air return opening 35 may be provided on the front cover plate 37.
In the using process of the refrigerator, the food in the storage chamber 2 is easy to emit peculiar smell, and the peculiar smell gradually fills the whole storage chamber 2 along with the cold air circulation of the refrigerator, so that the sanitation condition in the storage chamber 2 is damaged, therefore, in the embodiment, the air purifying device 5 is arranged in the air supply duct 33 to purify and deodorize the cold air in the air path circulation, thereby purifying the air in the storage chamber 2 and improving the sanitation condition. Specifically, as shown in fig. 3, the duct cover 4 is provided with an insertion opening 41 communicating with the air supply duct 33, and the odor purifying device 5 is inserted into the air supply duct 33 through the insertion opening 41. Thus, another simple design of installing and arranging the odor purifying device in the air duct is provided, the odor purifying device is accessible in the storage chamber, and the odor purifying device is convenient to disassemble and install so as to better replace the odor purifying and deodorizing component.
Fig. 4 is a schematic structural view of the odor eliminating device of the present embodiment, and fig. 5 is an exploded view of the odor eliminating device of fig. 4. Referring to fig. 4 and 5, the odor purifying device 5 includes a mounting frame and an odor purifying member 51 capable of being disposed on the mounting frame, the mounting frame specifically includes a bracket 52 and a plurality of frame slots 53 disposed on a back surface 521 of the bracket 52 facing the air supply duct 33, and the odor purifying member 51 is disposed and accommodated in the frame slots 53. The bottom of the frame groove 53 has a rib 531 to support the smell cleaning member 51. A stop 532 is provided on the side wall of the frame channel 53 to prevent the tendency of the odor purifying member 51 to disengage from the frame channel 53.
The plurality of frame slots 53 are at least two and are spaced laterally on the back side 521 of the frame 52. The predetermined space is maintained between each of the independent frame grooves 53, so that a circulation space is reserved for the wind to flow through the odor purifying device 5, the resistance to the wind when the wind flows through the odor purifying device 5 is reduced, the purification and deodorization effects of the odor purifying device 5 are ensured, and the wind flowing through the odor purifying device is blown into the storage chamber 2 smoothly with a small speed reduction.
The frame groove 53 extends the air blowing duct 33 by a length substantially equal to the thickness of the air blowing duct 33 in the direction away from the storage chamber 2. Thus, the air flowing through the air supply duct 33 inevitably flows through the entire smell cleaning member 51 in the frame groove 53, and the contact area between the smell cleaning member 51 in the frame groove 53 and the flowing air can be increased, thereby enhancing the smell removing and purifying effect.
As shown in fig. 3, the height of the frame groove 53 in the direction of the flow of the wind is substantially equal to the height of the insertion port 41 in that direction, so that the frame groove 53 is provided in cooperation with the insertion port 41.
The heat insulator 6 is provided between the frame groove 53 and the back surface 521 of the bracket 52. This prevents cold from being transmitted to the rack 52 too much, which would result in unnecessary condensation on the side of the rack 52 facing the storage compartment 2.
The insertion port 41 may be closed by a cover, and in particular, the bracket 52 is configured as a cover that can open or close the insertion port 41. The periphery of the insertion opening 41 is provided with a clipping hole 411, and when the bracket 52 is inserted into the insertion opening 41, a buckle 522 which can be clipped into the clipping hole 411 is arranged on the back surface 521 of the bracket 52 to enhance the fixing function.
The sealing member 7 is provided between the peripheral edge of the insertion port 41 and the rear surface 521 of the holder 52, thereby enhancing the sealing property and preventing air leakage.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
