[0035] The utility model provides a refrigerator liner structure and a refrigerator through improvement. The technical solution of the utility model is:
[0036] like Figure 1 As shown, a refrigerator liner structure includes:
[0037] The refrigerator shell 1 can prevent external heat from being transferred to the inside of the refrigerator, thereby maintaining a stable temperature inside the refrigerator.
[0038] Liner 2, such as Figure 1 , Figure 2 As shown, a partition 21 is provided in the middle of the inner tank 2, and the partition 21 divides the inner tank 2 into an upper working chamber 22 and a lower working chamber 23. The upper working chamber 22 can be set as a refrigerator or a freezer, and the lower working chamber 23 is set as a freezer corresponding to the refrigerator, or is set as a refrigerator corresponding to the freezer. Figure 2 As shown in FIG. 1 , the lower working chamber 23 is formed by a partition 21, a first back plate 231, a second back plate 232, a first bottom plate 233, a second bottom plate 234 and two side plates 235. A second layer plate 236 is provided in the lower working chamber 23. The second layer plate 236 is flush with the first bottom plate 233. A machine room 3 is provided between the first bottom plate 233, the second back plate 232 and the housing 1. The machine room 3 is located behind the lower working chamber 23. The machine room 3 is mainly used to store and protect the compressor and other mechanical parts of the refrigerator. The machine room 3 is set as a closed space to prevent dust, water and other pollutants from entering the machine room 3, thereby protecting the mechanical parts from damage.
[0039] In some embodiments, Figure 2 , Figure 3 As shown, the first bottom plate 233 and the second back plate 232 are fixedly connected, and an air guide groove 2331 is provided at the connection between the first bottom plate 233 and the second back plate 232. The air guide groove 2331 is used to guide cold air or cold wind to the area below the second layer plate 236 in the lower working chamber 23. This allows cold air to exist in the entire lower chamber, and the cold air can be blown into the placement space in front of the machine room 3, ensuring the preservation effect of vegetables, fruits and other foods placed there.
[0040] In some embodiments, Figure 3 As shown, the lower working chamber 23 is provided with a first layer plate 237, and the first layer plate 237 is used to separate the space in the lower working chamber 23 to place more food or to place the food in categories. The first layer plate 237 can be provided with multiple pieces to separate the lower working chamber 23 into more layers of space. The inner surface of the side plate 235 is provided with multiple fixed blocks 2351 and first fixed grooves 2352, and the two ends of the air guide groove 2331 are provided with second fixed grooves 2371. The first layer plate 237 is mounted on the fixed blocks 2351 and the first fixed grooves 2352, and the second layer plate 236 is mounted on the second fixed grooves 2371 and the fixed blocks 2351. The first fixed groove 2352 is used to fix the rear end of the first layer plate 237, the second fixed groove 2371 is used to place the rear end of the first layer plate 237, and the fixed block 2351 is used to place the front end of the first layer plate 237 and the second layer plate 236.
[0041] In some embodiments, Figure 3 As shown, a positioning groove 2353 is provided at one end of the first fixing groove 2352 close to the first back plate 231, and a positioning block (not shown in the figure) is provided at the first layer plate 237 corresponding to the positioning groove 2353. The positioning groove 2353 is used to position the first layer plate 237. After the first layer plate 237 is inserted into the first fixing groove 2352, the positioning block falls into the positioning groove 2353 under the action of gravity. The first layer plate 237 is fixed in the positioning groove 2353 and cannot move forward or backward, thereby realizing the positioning of the first layer plate 237. When the first layer plate 237 needs to be removed, the first layer plate 237 is lifted upward to disengage the positioning block from the positioning groove 2353, and then the first layer plate 237 is pulled out.
[0042] In some embodiments, Figure 3As shown, a light bar 2354 is provided on the side panel 235. The light bar 2354 is used for lighting, and the refrigerator inner tank structure may further include a door body hinged to the outer shell 1, and a Hall switch or a mechanical switch may be provided between the door body and the outer shell 1, and the switch of the light bar 2354 may be controlled by the Hall switch or the mechanical switch on the door body.
[0043] In some embodiments, a drawer (not shown in the figure) is provided between the second layer plate 236, the second back plate 232 and the second bottom plate 234, and a drawer positioning groove 23412353 is provided on the second bottom plate 234, and the drawer is used for preservation. The fresh-keeping chamber is composed of the second layer plate 236 and the drawer, and is a separately prepared space for storing food. Since the fresh-keeping chamber is wrapped by the second layer plate 236 and the drawer, the food placed therein is not easy to evaporate or air-dry, and can achieve a better preservation effect than the food directly placed in the refrigerator. And since an air guide groove 2331 is provided at the connection between the first bottom plate 233 and the second back plate 232, the air guide groove 2331 can directly guide the cold air into the drawer. By providing the air guide groove 2331 to cool the fresh-keeping chamber, the temperature in the fresh-keeping chamber is the same as the temperature of the lower working chamber 23, and the preservation effect of vegetables and fruits in the fresh-keeping chamber will not be affected.
[0044] In some embodiments, Figure 4 As shown, a first drain port 4241 is provided at the bottom of the upper working chamber 22, and a second drain port is provided at the lower working chamber 23, the second drain port is located at the connection between the first back plate 231 and the first bottom plate 233, the first drain port 4241 and the second drain port are both connected to a water pipe 43, a water tank is provided in the machine room 3, and the water pipe 43 is connected to the water tank. The first drain port 4241 and the second drain port are used to discharge condensed water, and the water tank is used to store accumulated water.
[0045] In some embodiments, Figure 5 As shown, a first air plate 221 is disposed at the rear of the upper working chamber 22, a first air outlet 2211 is provided on the first air plate 221, a first fan 2212 is disposed at the first air outlet 2211, and the first drain port 4241 is located between the first air plate 221 and the inner tank 2. The first fan 2212 is used to blow cold air out of the first air outlet 2211 on the first air plate 221.
[0046] In some embodiments, Figure 5As shown, the second drain port is lower than the first bottom plate 233, the first bottom plate 233 has a slope, sloping toward the first drain port 4241, a second air plate 238 is fixedly arranged in front of the first back plate 231, a drainage groove 2381 is provided at the lower end of the second air plate 238, and the drainage groove 2381 is used to discharge the condensed water in the lower working chamber 23 through the first drain port 4241. A second air outlet 2382 is provided on the second air plate 238, and a second fan 2383 is provided at the second air outlet 2382. The second fan 2383 is used to blow cold air out of the second air outlet 2382 on the second air plate 238.
[0047] In some embodiments, Figure 5 As shown, a first evaporator 222 is disposed between the first air plate 221 and the inner tank 2, and a second evaporator 239 is disposed between the second air plate 238 and the first back plate 231.
