Detailed ways

Embodiment one

Below in conjunction with accompanying drawing a kind of three evaporator refrigerators with refrigerating door system ice function described in the present invention, this refrigerator is that air-cooled refrigerator comprises refrigerating chamber 1, freezing chamber 2, the ice making chamber 3 that is connected with refrigerator door 4, and The relative rear of the refrigerator door is provided with an independent freezing evaporator chamber 21 and a refrigeration evaporator chamber 28. The freezing evaporator chamber 21 is provided with a first evaporator 22 and a freezing fan 23, and the refrigeration evaporator chamber 28 is provided with a second evaporator chamber. An independent ice-making evaporator chamber 25 is also provided at the rear relative to the refrigerator door. A third evaporator 26 and an ice-making fan 27 are arranged in the ice-making evaporator chamber 25. The ice-making evaporator chamber 25 is connected with the ice-making Between the chambers 3, there is an ice-making chamber air supply duct 31 and an ice-making chamber return air duct 32 communicating with each other. See Figure 1, Figure 2, and Figure 3, where the rear opposite to the refrigerator door refers to the rear of the refrigerator, if the refrigerator door is on the right side of the refrigerator in Figure 4, then the rear opposite to the refrigerator door is at the rear of the refrigerator in Figure 4 left side.

The refrigerating evaporator chamber 21 communicates with the freezing chamber 2 , the refrigerating evaporator chamber 28 communicates with the refrigerating chamber 1 , and the ice-making evaporator chamber 25 communicates with the ice-making chamber 3 . That is, the first evaporator 22 and the refrigerating fan 23 in the freezing evaporator chamber 21 provide cooling capacity for the freezing compartment 2, and the second evaporator 29 and the refrigerating fan in the refrigerating evaporator compartment 28 provide cooling capacity for the refrigerating compartment 1, making ice The third evaporator 26 and the ice making fan 27 in the evaporator chamber 25 provide cooling capacity for the ice making chamber 3 . The three circulatory systems are independent of each other, so as to avoid the mutual "smell" between the refrigerating room, the freezing room and the ice making room, and ensure that the ice cubes have no peculiar smell. The room air supply duct and the ice-making room return air duct can also ensure fast ice making. In FIG. 1 , the dotted line represents the ice-making room return air duct 32 .

The ice-making compartment 3 is connected to the door of the refrigerating compartment 1; the freezing evaporator compartment 21 is arranged behind the freezing compartment 2, the ice-making evaporator compartment 25 is also arranged behind the freezing compartment 2, and the refrigerating evaporator compartment 28 is arranged in the refrigerating compartment 1 the rear. The refrigerating evaporator chamber 21 and the ice-making evaporator chamber 25 are separated by a baffle plate 24 and distributed on the left and right to form two relatively independent and unconnected spaces. The left and right distribution between the chambers 25 is also conducive to the arrangement of the ice-making chamber air supply duct 31 and the ice-making chamber return air duct 32 in the refrigerator wall.

One end of the air supply channel 31 of the ice making room is connected with the air supply port 33 of the ice making room 3, and the other end of the air supply channel 31 of the ice making room is connected with the air outlet 252 of the ice making evaporator on the upper part of the ice making evaporator room 25 . One end of the return air passage 32 of the ice making chamber is connected with the air outlet 34 of the ice making chamber 3, and the other end of the return air passage 32 of the ice making chamber is connected with the air inlet 251 of the ice making evaporator at the lower part of the ice making evaporator chamber 25 ,Figure 1. Cold air with a high density tends to move downward, while hot air with a low density tends to move upward. Setting the ice-making evaporator air outlet 252 and the ice-making evaporator air inlet 251 is conducive to the rapid flow of cold air and improves ice-making efficiency.

The ice-making compartment return air duct 32 includes a first section return air duct 321 arranged in sequence on the side wall of the ice-making compartment air outlet 34 of the refrigerator, a second section arranged in the partition 5 between the refrigerator compartment 1 and the freezer compartment 2 The segment air return duct 322 and the third segment return air duct 323 arranged behind the third evaporator 26 are shown in FIG. 1 and FIG. 2 . The advantage of setting the third return air duct 323 behind the third evaporator 26 is that the temperature of the third evaporator 26 is relatively low during operation, and the cold energy will not only be transferred to the ice making room but also to the surroundings. The cold energy transferred is invalid, that is, useless work. The hotter cold air in the third section of return air passage 323 will absorb the cold energy transferred from the third evaporator 26 to the surroundings, reducing the temperature of the air in the third section of return air passage 323. In this way, the loss of cold energy transferred from the third evaporator 26 to the surroundings is reduced, energy is saved, and ice-making efficiency is improved.

The third return air passage 323 is linear as shown in FIG. 2 , and the air inlet 251 of the ice-making evaporator is arranged at the bottom center of the rear wall 253 of the ice-making evaporator chamber. The air inlet 251 of the ice-making evaporator is arranged at the bottom center of the rear wall 253 of the ice-making evaporator chamber, so that the air inlet 251 of the ice-making evaporator faces the bottom center of the third evaporator 26, so that the entire third evaporator 26 can participate in Refrigeration, avoid local uneven heating and cooling, improve cooling efficiency.

A refrigerating fan can also be arranged in the refrigerating evaporator chamber 28, that is, the refrigerating chamber can adopt a direct cooling mode or an air cooling mode, as shown in the schematic circuit diagrams in FIGS. 7 and 8 .

The upper part of the ice making room 3 is provided with an ice maker 35, and the lower part is provided with an ice storage box 36. The air supply port 33 of the ice making room of the ice making room 3 is arranged on the upper part of the ice making machine 35, as shown in Fig. 5, the upper left side of the ice making room The side is provided with an air supply port 33 of the ice making chamber.

Alternatively, an ice maker 35 is arranged on the upper part of the ice making chamber 3, and an ice storage box 36 is arranged on the lower part, and the air outlet 33 of the ice making chamber of the ice making chamber 3 is arranged between the ice maker 35 and the ice storage box 36, as shown in the figure 5. An air supply port 33 for the ice-making chamber is provided in the middle of the left side of the ice-making chamber. In this way, the cold air enters from the bottom of the ice machine, and the freezing direction in the ice machine is from bottom to top. The volume of water will increase when converted into ice, and the ice will be frozen from bottom to top. The ice cubes can adjust their volume changes in the ice machine. Compared with freezing ice from top to bottom, although the ice making speed may be slower, it can avoid the expansion of frozen ice and damage to the ice machine. Or, at the same time, in order to speed up the ice-making speed, there are two ice-making chamber air supply outlets 33 of the ice-making chamber 3, which are respectively arranged on the top of the ice maker 35 and between the ice maker 35 and the ice storage box 36, as shown in FIG. 5 .

The principle diagram of the refrigerator circuit of the present invention is shown in Fig. 7 and Fig. 8. The freezing evaporator is the first evaporator, the refrigeration evaporator is the second evaporator, and the ice-making evaporator is the third evaporator. Figure 9, the refrigeration evaporator, that is, the second evaporator, is connected in parallel with the ice-making evaporator, that is, the third evaporator, and then connected in series with the freezing evaporator, that is, the first evaporator; or Figure 10, the freezing evaporator, that is, the first evaporator and the ice-making evaporator The refrigerating evaporator, that is, the third evaporator, is connected in series and then connected in parallel with the refrigerating evaporator, that is, the second evaporator. You can also refer to Chinese patent CN 101903718A, published on December 1, 2010. How the ice evaporator is set.

The refrigerator of the invention can quickly produce ice cubes with pure taste.
