Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

The invention provides a refrigerator which comprises a refrigerator body with an opening at the front end and a door arranged at the front part of the refrigerator body. The door is pivotable about an axis to open or close the cabinet. A storage space is defined within the enclosure.

The storage space is divided into a plurality of independent compartments by partitions, wherein the compartments comprise a refrigerating compartment and a freezing compartment.

The door includes a refrigerating chamber door body which can pivotally open or close the refrigerating chamber, and a freezing chamber door body which can pivotally open or close the freezing chamber.

a refrigerating system is arranged in the box body. The refrigerating system is used for providing cold energy for the compartment and/or the ice making chamber so as to reduce the temperature in the compartment and the ice making chamber.

The refrigerating system comprises a compressor, a condenser, a drying filter, a control valve, a capillary tube and an evaporator which are connected through a refrigerant pipeline to form a loop. A compressor installed in the machine room is used to compress refrigerant. The evaporator absorbs heat to cool the compartment and the ice making chamber, and the condenser absorbs heat of the evaporator and forcibly dissipates heat.

when the compressor is operated, the refrigerant changed into a gaseous state by the evaporator flows to the compressor and is compressed, the compressed refrigerant is condensed into a high-pressure liquid state while passing through the condenser, and the pressure is reduced after passing through the capillary tube, and flows to the evaporator again. The refrigerant is evaporated to a gaseous state after heat exchange in the evaporator. The air around the evaporator is cooled to form cold air, and the cold air is sent into each compartment and/or the ice making compartment through the air supply channel, is circulated in each compartment for heat exchange, and flows back to the periphery of the evaporator through the air return channel.

referring to fig. 1, in an embodiment of the present invention, a heat insulation space is disposed in a refrigerating chamber door 10, and an ice making chamber is accommodated in the heat insulation space, and an ice maker 20, an ice bank, and a water supply device are disposed in the ice making chamber.

The air inlet 30 and the air outlet 40 of the ice making chamber are positioned on the side wall 11, and the air inlet 30 is positioned above the air outlet 40. When the door 10 is closed, the door 10 abuts against the side wall of the box, and the air inlet 30 and the air outlet 40 are respectively communicated with the air inlet channel and the air outlet channel on the side wall of the box to form an ice making air path circulation. The cold air around the evaporator reaches the ice making chamber through the air inlet channel for heat exchange, and then flows back to the periphery of the evaporator through the air outlet channel. When the door 10 is opened, the air inlet 30 and the air outlet 40 are respectively disconnected from the air inlet channel and the air outlet channel.

Referring to fig. 1 and 2, a cooling guide member is provided in the ice making chamber to guide cooling energy from the blowing duct to all places of the ice making chamber. The cold conducting member includes a first cold conducting plate 51 and a second cold conducting plate 52, and may also include more vertically arranged cold conducting plates. The first cold conducting plate 51 is located above the second cold conducting plate 52, and both are installed in the ice making chamber through a support member to form an inner wall of the ice making chamber, wherein the first cold conducting plate 51 is in direct contact with the ice making machine 20. The first and second cold conductive plates 51, 52 have a gap therebetween to insulate the two. Since the cold energy of the cold guiding plate is conducted to all directions, the cold energy of the first cold guiding plate 51 can be supplied to the ice maker 20 in a centralized manner, and is prevented from being dispersed to the second cold guiding plate 52.

The cold guide piece is of an L-shaped or U-shaped structure so as to semi-enclose the ice making chamber. Taking the first cold conducting plate 51 as an example, the body 513 is closely attached to the aluminum groove of the ice maker 20, and the body 513 extends at an included angle to form the bent portion 511. The bent portion 511 is parallel to the sidewall 11 with a space.

The second cold conductive plate 52 is similar to the first cold conductive plate 51 in structure, and the bent portion 521 extends from the body 523 at an angle. The bent portion 521 is adjacent to the side wall 11, parallel to the side wall 11 and spaced apart from the side wall 11.

the first cold guiding plate bending portion 511, the second cold guiding plate bending portion 521, the side wall 11 and the front and rear walls of the ice making chamber enclose to form a closed air duct. The cool air from the box inlet channel enters the channel from the inlet 30 and returns to the outlet channel from the outlet 40.

Preferably, the bent portion 511 is opposite to the intake opening 30, and the bent portion 521 is opposite to the outtake opening 40. That is, the cold air is in contact with the first cold conduction plate 51 and the second cold conduction plate 52 in this order. This arrangement allows the ice maker 20 connected to the first cold conductive plate 51 to obtain more cooling energy.

Referring to fig. 3, it is preferable that the surfaces of the bent portions 511 and 521 opposite to the side wall 11 be provided with fins 60 to increase a contact area with the cool wind.

The embodiment arranges the cold guide piece in the ice making chamber, and guides cold energy into the ice making machine and other parts in a contact conduction mode, thereby avoiding the problems of tainting odor, ice block sublimation and the like caused by directly guiding cold air into the ice making machine and the periphery.

referring to fig. 4, a second embodiment of the present invention is different from the first embodiment in that the cold conducting plate is a unitary superconducting plate 53, in which a plurality of horizontal microchannels are disposed, and in which the cold conducting medium is contained, so that the cold can be efficiently conducted in the horizontal direction. The micro-channels are isolated by channel walls, so that the thermal conductivity of the micro-channels in the vertical direction is negligible.

Superconducting plate 53 includes a body 533 and a bent portion 531 extending at an angle. The bent portion 531 is adjacent to the sidewall 11, parallel to the sidewall 11 and spaced apart therefrom. The curved portion 531, the side wall 11 and the front and rear walls of the ice making chamber enclose a closed air duct.

The ice maker 20 is attached to the upper side of the body 533. The air inlet 30 is approximately at the same level as the ice maker 20, and the air outlet 40 is approximately flush with the lower edge of the superconducting plate 53. This arrangement allows the ice maker 20 to obtain maximum cooling capacity, since the cooling capacity is conducted horizontally in the superconducting plate 53, and ensures that sufficient cooling capacity is obtained also at the bottom of the superconducting plate 53.

Referring to fig. 5, preferably, the surface of the bent portion 531 opposite to the side wall 11 is provided with a fin 60 to increase a contact area with the cool wind.

The superconducting plate has high thermal conductivity, the micro channel extending in the horizontal direction ensures the directional transmission of cold energy, and the ice maker can obtain the maximum supply of cold energy in the refrigeration chamber by combining the position matching of the air inlet and the ice maker.

In the third embodiment of the present invention, a heat insulating space is provided in the refrigerating chamber, and an ice making chamber is accommodated therein, and an ice maker 20, an ice bank, and a water supply device are provided in the ice making chamber.

The ice making chamber is fixed to a mounting wall of the refrigerating chamber, which may be a side wall or a rear wall. Referring to fig. 6 and 7, a cooling guide member is disposed in the ice making chamber, and the cooling guide member includes a first cooling guide plate 51 and a second cooling guide plate 52, or may include more cooling guide plates arranged in a vertical direction. The first cold conducting plate 51 is located above the second cold conducting plate 52, and both are installed in the ice making chamber through a support member, forming an inner wall of the ice making chamber, wherein the first cold conducting plate 21 is in direct contact with the ice making machine 20. The first and second cold conductive plates 51, 52 have a gap therebetween to insulate the two. Since the cold energy of the cold guiding plate is conducted to all directions, the cold energy of the first cold guiding plate 51 can be supplied to the ice maker 20 in a centralized manner, and is prevented from being dispersed to the second cold guiding plate 52.

the cold guide piece is of an L-shaped or U-shaped structure so as to semi-enclose the ice making chamber. Referring to fig. 7, taking the first cold conducting plate 51 as an example, the body 513 is closely attached to the aluminum groove of the ice maker 20, and the body 513 extends at an included angle to form a bent portion.

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

The insulating layer of the cold storage compartment mounting wall has an air duct 70 therein for supplying air to the compartment. The mounting wall is used for fixing the ice making chamber and is in contact with the body of the cold guide member. The air duct 70 is provided with an air port 71 adjacent to the cold guide to send cold air to the cold guide. As shown in fig. 6, the first cold conduction plate 51 and the second cold conduction plate 52 may be provided with an air inlet 71, or an air inlet may be provided to penetrate each of the cold conduction plates 51 and 52 (not shown). The cold air in the air duct 70 flows from top to bottom and contacts the first cold conduction plate 51 and the second cold conduction plate 52 in sequence, so that the ice making machine 20 connected with the first cold conduction plate 51 can obtain more cold.

The air opening 71 is provided upstream of the air inlet of the refrigerating chamber to preferentially secure the cooling capacity of the ice maker 20.

Preferably, a surface of the cold guide contacting the tuyere 71 is provided with a fin (not shown) to increase a contact area with the cold wind.

The ice making chamber in the box body is provided with the cold guide piece, an air supply channel of the compartment can be shared, cold energy is guided into the ice making machine and other parts in a contact conduction mode, and the problems of tainting of smell, ice block sublimation and the like caused by directly guiding cold air into the ice making machine and the periphery can be avoided.

Referring to fig. 8 and 9, another embodiment of the present invention is different from the third embodiment in that the cold conducting plate is an integrated superconducting plate 53, in which a plurality of horizontal microchannels are disposed, and the cold conducting medium is contained in the microchannels, so that the cold can be efficiently conducted in the horizontal direction. The micro-channels are isolated by channel walls, so that the thermal conductivity of the micro-channels in the vertical direction is negligible.

The air duct 70 is provided with an air port 71 adjacent to the superconducting plate 53 to supply cold air to the superconducting plate 53. The air opening 71 is one, and has a top end and a bottom end substantially flush with the top end and the bottom 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 cold air in the vertical direction and horizontally transfer the cold to all parts of the ice making chamber.

Superconducting plate 53 includes a body 533 and a bent portion extending at an angle. The body 533 is adjacent to a mounting wall of the refrigerating chamber, and the ice maker 20 is attached to the body 533 near an upper side. This arrangement allows the ice maker 20 to obtain more cooling energy than the components below it because the wind of the wind tunnel 70 moves from top to bottom.
