The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
As shown in fig. 1 to 6, the refrigerator includes a cabinet 100, a door 200, an ice making compartment 300, and a refrigerating system. The cabinet 100 includes a refrigerating compartment 110 and a freezing compartment 120. The refrigerating system includes a compressor 410, a condenser 420, a refrigerating capillary tube 431 and a refrigerating evaporator 430 provided in the refrigerating chamber 110, a freezing capillary tube 441 and a freezing evaporator 440 provided in the freezing chamber 120, and an ice making capillary tube 451 and an ice making evaporator 450 provided in the ice making compartment 300. A pressing machine compartment is provided at the rear side of the freezing chamber 120, and the compressor 410 and the condenser 420 are provided in the pressing machine compartment. As shown in fig. 2, an electromagnetic valve 421 is disposed at one end of the condenser 420, the refrigerating capillary 431 and the refrigerating evaporator 430 are connected in series between the electromagnetic valve 421 and the compressor 410, the ice making capillary 451 and the ice making evaporator 450 are connected in series, and after two serial branches are connected in parallel with the freezing capillary 441, the two serial branches are connected in series with the freezing evaporator 440, that is, the refrigerant selectively enters the refrigerating capillary, the freezing capillary and the ice making capillary via the electromagnetic valve 421, the refrigerant reaches the refrigerating evaporator via the refrigerating capillary, the refrigerant reaches the ice making evaporator via the ice making capillary, and then the refrigerant from the refrigerating evaporator, the ice making evaporator and the freezing capillary all enters the freezing evaporator and returns to the compressor. Accordingly, the refrigerating processes of the refrigerating chamber 110, the freezing chamber 120, and the ice-making chamber 300 may be independently controlled. The ice cubes produced in the ice making chamber have high glittering and translucent degree and do not taint with odor.
The condenser 420 and the ice making capillary tube 451 are connected by a refrigerant tube assembly 460, and the ice making evaporator 450 and the freezing evaporator are connected by an ice making return tube assembly 470. In the embodiment of the present invention, as shown in fig. 3, both ice making capillary 451 and ice making evaporator 420 are provided on door 200. The ice making capillary 451 and the ice making air return tube assembly 470 are parallel to each other and are embedded adjacent to each other in the foaming layer of the door 200.
Therefore, according to the refrigerator disclosed by the invention, the ice making capillary tube 451 is arranged on the door body 200, so that the part of the refrigerant tube assembly 460 entering the door body 200 from the refrigerator body 100 is a normal-temperature pipeline, and a heat preservation structure and a condensation prevention structure do not need to be arranged on the part; and, the refrigerant in the refrigerant pipe assembly 460 does not exchange heat with the room temperature air, and the cooling efficiency is also improved.
In another embodiment, the refrigerating chamber and the freezing chamber may share the same evaporator, and the embodiment of the present invention is not limited thereto.
In addition, the ice making capillary tube 451 and the ice making air return tube 470 on the door 200 are parallel to each other and tightly attached to each other in the door 200, and since the ice making capillary tube 451 and the ice making air return tube 470 are both copper tubes, the heat exchange effect of the two is good. In addition, the ice making capillary tube 451 and the ice making air return tube assembly 470 are both arranged on the door body, so that the opening and closing of the door body cannot influence the heat exchange effect of the ice making capillary tube 451 and the ice making air return tube assembly 470, and the stability is good. After the ice making capillary tube 451 exchanges heat with the ice making air return tube assembly 470, the refrigerant with high temperature and high pressure enters the ice making capillary tube 451 and flows to the ice making evaporator 450, the refrigerant with normal temperature and low pressure is output from the first air return tube 471 of the ice making air return tube assembly 470, the first flexible tube 462 in the refrigerant pipe assembly 460 is connected with the ice making capillary tube 451, the second flexible tube 472 in the ice making air return tube assembly 470 is connected with the ice making evaporator 450, and the first flexible tube 462 and the second flexible tube 472 pass through between the box body 10 and the door body 200 and are exposed to the ambient temperature, but there is no condensation risk.
In the embodiment of the present invention, as shown in fig. 3 to 4, the refrigerant pipe assembly 460 includes a first connection pipe 461, a first flexible pipe 462 and a second connection pipe 433 which are connected in sequence. A first connection pipe 461 is connected to the condenser 420, and a second connection 433 is connected to the ice-making evaporator 420. In practice, an ice making capillary tube 451 is further connected between the second connection pipe 433 and the ice making evaporator 420.
Further, the ice-making air return pipe assembly 470 includes a first air return pipe 471, a second flexible pipe 472 and a second air return pipe 473 connected in sequence, wherein the first air return pipe 471 is connected to the ice-making evaporator 420, and the second air return pipe 473 is connected to the compressor. In fact, a refrigeration evaporator 440 can also be connected between the second muffler 422 and the compressor.
In the embodiment of the present invention, the door 200 is rotatably connected to the cabinet 100 by a hinge, and a hinge box 130 for accommodating the hinge is disposed at the top of the refrigerator. In addition, the refrigerant pipe assembly 460 passes through the hinge box 130 from the cabinet 100 and extends to the door body 200, and the ice making return air pipe assembly 470 passes through the hinge box 130 from the door body 200 and extends into the cabinet 100. The refrigerant pipe assembly 460 and the ice-making air return pipe assembly 470 respectively pass through the hinge box 130, so that a part of the two pipelines can be located in the hinge box 130, and the distribution of the refrigerant pipe assembly 460 and the ice-making air return pipe assembly 470 does not affect the opening and closing of the door body 200, and is not exposed outside the door body 200 and the refrigerator body 100 to affect the appearance.
Specifically, the first and second flexible tubes 462, 472 may be located within the hinge box 130. Because the first flexible tube 462 and the second flexible tube 472 are made of soft materials, both of them are disposed in the hinge box 130, and the two flexible tubes can be bent when the door is opened or closed, so that the door body 200 can be opened or closed more conveniently.
In fact, the top of the door and the top of the cabinet are each provided with a portion of the hinge box 130, which can be abutted when the door is closed, so as to completely shield the refrigerant tube assembly 460 and the ice-making air return tube assembly 470, and thus the piping assembly is not exposed.
In the embodiment of the present invention, as shown in fig. 4, a first fixing ring 4621 and a second fixing ring 4622 are respectively disposed at two ends of the first flexible tube 462, the first fixing ring 4621 is fixedly connected to the first connection tube 461, the second fixing ring 4622 is fixedly connected to the second connection tube 433, and the first fixing ring 4621 and the second fixing ring 4622 are respectively in interference fit with the first flexible tube 462. Generally, the first connecting tube 461 and the second connecting tube 432 are hard metal tubes, and the first flexible tube 462 is a flexible tube made of nylon or the like. Then, the connection between the first connection tube 461 and the second connection tube 432 and the first flexible tube needs to be made of two different materials and can achieve better sealing performance. The first fixing ring and the second fixing ring are respectively arranged at two ends of the first flexible pipe, and the first fixing ring 4621 and the second fixing ring 4622 are respectively in interference fit with the first flexible pipe, so that the sealing performance at the first flexible pipe can be enhanced. Specifically, the first fixing ring 4621 and the second fixing ring 4622 are metal rings, and the metal rings can be welded to the first connecting tube 461 and the second connecting tube 432, respectively, so that the connecting tubes and the fixing rings can maintain a seal therebetween. In addition, the first fixing ring 4621 and the second fixing ring 4622 are respectively in interference fit with the first flexible tube, specifically, the outer diameter of the first flexible tube is larger than the inner diameter of the first fixing ring 4621 and the second fixing ring 4622, so that both ends of the first flexible tube are tightly pressed against the inner walls of the first fixing ring 4621 and the second fixing ring 4622. In this way, the joints between the first connection pipe 461 and the second connection pipe 432 and the first flexible pipe can maintain good sealing performance.
Further, the portions of the first fixing ring 4621 and the second fixing ring 4622 connected to the first flexible tube 462 are coated with a sealing liquid. By applying the sealing liquid to the joints of the two ends of the first flexible tube 462, the sealing property of the joints of the first flexible tube 462 and the first and second connection tubes 461 and 433 can be improved, and leakage of the refrigerant can be prevented.
Furthermore, the first fixing ring and the second fixing ring are both located in the hinge box. That is, the joints of the first connection tube 461, the second connection tube 433 and the first flexible tube 462 are disposed in the hinge box 130 and are not exposed to the outside of the refrigerator, and the joints (i.e., the first fixing ring and the second fixing ring) are more convenient to maintain if there are problems such as damage or refrigerant leakage.
In an embodiment of the present invention, a detection sensor is further disposed in the hinge box 130 near the first flexible tube 462. The refrigerator also comprises a controller in communication connection with the detection sensor. The detection sensor is used for detecting whether refrigerant leaks around the first flexible pipe or not and sending a confirmation signal to the controller after the refrigerant leakage is detected. The controller is used for sending out a fault prompt after receiving the confirmation signal.
In the embodiment of the present invention, two fixing rings may be disposed at two ends of the second flexible tube 472 in the ice-making air return tube assembly 470, and are respectively welded to the first air return tube 471 and the second air return tube 442. Meanwhile, the two fixing rings are respectively interference-fitted with the second flexible pipe 472. In addition, sealing liquid is coated on the portions where the two fixing rings are connected to the second flexible tube 472. Further, since the second flexible tube 472 and the fixing ring thereof are also provided in the hinge box 130, the detection sensor may actually detect whether there is a refrigerant leakage around the second flexible tube. In fact, since the first flexible tube 462, the second flexible tube 472, and the detection sensor are disposed in the hinge box, and the detection sensor detects whether the air around the hinge box 130 contains halogen, the refrigerant leakage can be detected at the connection of the first flexible tube 462 or the connection of the second flexible tube 472.
Further, the first flexible tube 462 and the second flexible tube 472 may be disposed in parallel within the hinge box 130. Thus, the arrangement of the two flexible pipes is facilitated, and the winding is not easy to occur.
Preferably, the length of the first flexible tube 462 may be greater than the size of the hinge box 130 in the thickness direction of the door body 200. Similarly, the length of the second flexible tube 472 may be greater than the size of the hinge box 100 in the thickness direction of the door body 200. Therefore, the door 200 does not pull the refrigerant pipe assembly 430 and the ice-making air return pipe assembly 470 when opening and closing.
Preferably, the ice-making muffler assembly 470 is located in the cabinet 100 and is embedded in a foaming layer on a sidewall of the cabinet 100. That is, the second air return pipe 473 is embedded in the foam layer on the sidewall of the box 100, so that the second air return pipe 473 does not exchange heat with the air in the box, thereby improving the cooling efficiency.
As shown in fig. 5, an ice tray 310 is disposed in the ice making compartment 300, and a defroster is disposed on an upper surface of the ice tray 310. The refrigerator also comprises a controller electrically connected with the defrosting device; the controller is used for controlling the defrosting device to be started when a defrosting instruction is received.
