Detailed ways

The invention will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, the embodiments are not intended to limit the invention, and the structural, method, or functional changes made by those skilled in the art in accordance with the embodiments are included in the scope of the present invention.

The invention provides a refrigerator comprising a box having an open front end and a door disposed at a front portion of the box. The door can be pivoted about the axis to open or close the case. The storage space is defined in the cabinet.

The storage space is divided by partitions into a number of separate compartments, including a refrigerating compartment and a freezing compartment.

The door includes a refrigerating compartment door that pivotally opens or closes the refrigerating compartment, and a freezing compartment door that pivotally opens or closes the freezing compartment.

A refrigeration system is provided in the cabinet. The refrigeration system is used to provide cooling to the compartment and/or the ice making compartment to reduce the temperature in the compartment and the ice making compartment.

The refrigeration system includes a compressor, a condenser, a drying filter, a control valve, a capillary, and an evaporator that are connected by a refrigerant line to form a circuit. A compressor installed in the machine room is used to compress the refrigerant. The evaporator absorbs heat to cool the compartment and the ice making compartment, and the condenser absorbs heat from the evaporator and forces heat dissipation.

When the compressor is running, the refrigerant that has become gaseous through the evaporator flows to the compressor and is compressed. The compressed refrigerant is condensed into a high-pressure liquid state as it passes through the condenser, and the pressure is lowered after passing through the capillary, and flows to the evaporator again. The refrigerant evaporates into a gaseous state after heat exchange in the evaporator. The air around the evaporator is cooled to form cold air, and is sent to the respective chambers and/or the ice making chamber through the air supply passage, and heat is exchanged in each chamber, and is returned to the evaporator through the return air passage.

Referring to Fig. 1, in an embodiment of the present invention, a refrigerating compartment door body 10 is provided with a heat insulating space for containing an ice making compartment, and an ice making machine 20, an ice storage box and a water supply device are disposed in the ice making compartment.

The air inlet 30 and the air outlet 40 of the ice making compartment are located on the side wall 11, and the air inlet 30 is above the air outlet 40. When the door body 10 is closed, the door body 10 abuts against the side wall of the box body, and the air inlet 30 and the air outlet 40 respectively communicate with the air inlet passage and the air outlet passage located at the side wall of the box body to form an ice making air circulation. The cold air around the evaporator passes through the air inlet passage to the ice making chamber for heat exchange, and then flows back to the evaporator through the air outlet passage. When the door body 10 is opened, the air inlet 30 and the air outlet 40 are disconnected from the air inlet passage and the air outlet passage, respectively.

Referring to Figures 1 and 2, a cooling member is disposed in the ice making chamber to conduct the cooling amount from the air supply passage to the entire ice making chamber. The cooling member includes a first cooling plate 51 and a second cooling plate 52, and may further include more vertically arranged cooling plates. The first heat guide plate 51 is located above the second heat guide plate 52, and both are installed in the ice making chamber through the support member to form an inner wall of the ice making chamber, wherein the first heat guide plate 51 is in direct contact with the ice maker 20. There is a gap between the first cold guide plate 51 and the second cold guide plate 52 to insulate the two. Since the cooling amount of the cold guide plate is conducted in various directions, the cold amount of the first cold guide plate 51 can be concentratedly supplied to the ice maker 20 to avoid dispersion to the second cold guide plate 52.

The cooling member is of an L or U-shaped structure to partially enclose the ice making chamber. Taking the first cold guide plate 51 as an example, the body 513 is closely attached to the aluminum slot of the ice maker 20, and the body 513 extends at an angle to form a curved portion 511. The bent portion 511 is parallel to the side wall 11 and has a space.

The second heat guide plate 52 is similar in structure to the first heat guide plate 51, and the bent portion 521 extends from the body 523 at an angle. The curved portion 521 is adjacent to the side wall 11 and is parallel to the side wall 11 and has a space.

The first cold plate bending portion 511, the second cold plate bending portion 521, the side wall 11 and the front and rear walls of the ice making chamber are enclosed to form a closed air passage. The cold air from the inlet passage of the tank enters the air passage from the air inlet 30, and returns to the air passage from the air outlet 40.

Preferably, the bent portion 511 is opposed to the air inlet 30, and the bent portion 521 is opposed to the air outlet 40. That is, the cold air is in contact with the first cold guide plate 51 and the second cold guide plate 52, respectively.

The cold amount can be efficiently conducted in the horizontal direction. Since the microchannels are separated by channel walls, their thermal conductivity in the vertical direction is negligible.

The superconducting plate 53 includes a body 533 and a bent portion 531 formed at an angle. The bent portion 531 is adjacent to the side wall 11 and is parallel to the side wall 11 and has a space. The curved portion 531, the side wall 11, and the front and rear walls of the ice making chamber are enclosed to form a closed air passage.

The air inlet 30 is substantially at the same level as the ice maker 20, and the air outlet 40 is substantially flush with the lower edge of the superconducting plate 53. Since the cooling amount is horizontally conducted in the superconducting plate 53, the arrangement allows the ice maker 20 to obtain the maximum amount of cooling, and also ensures that the bottom of the superconducting plate 53 can also obtain a sufficient amount of cooling.

Referring to FIG. 5, preferably, the curved portion 531 is provided with fins 60 on the surface opposite to the side wall 11 to increase the contact area with the cold air.

Referring to FIGS. 6 and 7, a cooling member is disposed in the ice making chamber, and the guiding member includes a first cooling plate 51 and a second cooling plate 52, and may further include more vertically arranged cooling plates. The first heat guide plate 51 is located above the second heat guide plate 52, and both are installed in the ice making chamber through the support member to form an inner wall of the ice making chamber, wherein the first heat guide plate 21 is in direct contact with the ice maker 20. There is a gap between the first cold guide plate 51 and the second cold guide plate 52 to insulate the two. Since the cooling amount of the cold guide plate is conducted in various directions, the cold amount of the first cold guide plate 51 can be concentratedly supplied to the ice maker 20 to avoid dispersion to the second cold guide plate 52.

The cooling member is of an L or U-shaped structure to partially enclose the ice making chamber. Referring to FIG. 7, the first heat guide plate 51 is taken as an example, and the body 513 is closely attached to the aluminum groove of the ice maker 20, and the body 513 extends at an angle to form a curved portion.

The second cold guide plate 52 is similar in structure to the first cold guide plate 51 and may be L-shaped or U-shaped.

The heat insulating layer of the refrigerating compartment mounting wall has a duct 70 for supplying air to the compartment. The mounting wall is for fixing the ice making chamber and is in contact with the body of the cooling member. The air duct 70 is provided with a tuyere 71 adjacent to the cold guide to send cold air to the cold guide. As shown in FIG. 6, the tuyere 71 may be provided to each of the first cold guide plate 51 and the second cold guide plate 52, and a tuyeres may be provided to penetrate each of the cold guide plates 51 and 52 (not shown). The cold air in the air duct 70 flows from the top to the bottom, and is in contact with the first cold guide plate 51 and the second cold guide plate 52, so that the ice maker 20 connected to the first cold guide plate 51 can be more cold. the amount.

The tuyere 71 is disposed upstream of the air inlet of the refrigerating compartment to preferentially ensure the cooling capacity of the ice maker 20.

Preferably, the surface of the cooling member that is in contact with the tuyere 71 is provided with fins (not shown) to increase the contact area with the cold air.

The ice-making room in the box body is provided with a cooling member, which can share the air supply passage of the compartment, and introduces the cold amount into the ice making machine and other components in a contact conduction manner, thereby avoiding direct introduction of cold air into the ice maker and surrounding places. The resulting odor, ice sublimation and other issues.

Referring to FIG. 8 and FIG. 9, another embodiment of the present invention is different from the third embodiment in that the cold guide plate is an integral superconducting plate 53 in which a plurality of horizontal microchannels are arranged, and the microchannels are accommodated. The cooling medium can efficiently conduct the cooling in the horizontal direction. Since the microchannels are separated by channel walls, their thermal conductivity in the vertical direction is negligible.

The air duct 70 is provided with a tuyere 71 adjacent to the superconducting plate 53 to send cold air to the superconducting plate 53. The tuyere 71 is one, and the top end and the bottom end are substantially flush with the top end and the lower end of the superconducting plate 53, leaving only a small amount of space for sealing, so that the superconducting plate 53 can be in contact with the cold air in the vertical direction. And pass the cold level to all parts of the ice making room.

The superconducting plate 53 includes a body 533 and a bent portion formed at an angle. The body 533 is adjacent to the mounting wall of the refrigerating compartment, and the ice maker 20 is attached to the upper side of the body 533. Since the wind of the duct 70 moves from the top to the bottom, such an arrangement allows the ice maker 20 to obtain more cooling than the components below it.
