As shown in fig. 1, a refrigerator 100 having an air processing apparatus includes: a refrigerator 1 configured to refrigerate or freeze a storage such as food; and an air processing apparatus 5 provided in a predetermined portion of the refrigerator and configured to process air of a room in which the refrigerator 100 is installed. The meaning of the air treatment performed by the air treatment device 5 may mean that at least one of filtering, cooling, and dehumidifying is performed on the inside air of the room in which the refrigerator is installed. Fig. 1 illustrates that an air treatment apparatus 5 is installed on a top surface of a refrigerator 1 as one embodiment. The air treatment device 5 according to the present disclosure may be mounted to one of the bottom surface and the side surface.

The refrigerator 1 includes: a first housing 11; a storage chamber 12 provided in the first cabinet and defining a space for storing food therein; and a first door 15 for opening and closing the storage chamber.

The first housing 11 includes a front surface 11a, a rear surface 11c, a top surface 11b, and a side surface 11 d. The first door 15 is coupled to the front surface 11a, and the air processing apparatus 5 is detachably mounted on the top surface 11 b.

As shown in fig. 2, the storage chamber 12 is defined in the first cabinet 11, and can communicate with the outside of the first cabinet 11 via an opening 111 formed in a front surface 11a of the first cabinet. The first door 14 is coupled to the first housing 11 to open and close the opening 111.

The temperature within the storage chamber 12 is controlled by the first cooling unit 16. Generally, the first cooling unit 16 may be configured to maintain the interior of the storage compartment 12 at room temperature or lower. Fig. 2 illustrates that the first cooling unit 16 is configured to control the temperature inside the storage chamber 12 provided as one space. As an alternative example, the first cooling unit 16 may be configured to control two or more partitioned spaces at different temperatures.

The first cooling unit 16 may include: a first refrigerant pipe 169 for forming a circulation path of the refrigerant; a first compressor 165 for circulating a refrigerant along a first refrigerant pipe 169; a first condenser 163 for condensing the refrigerant by heat-exchanging the refrigerant discharged from the first compressor 165 with the outside air of the storage chamber 12 (or radiating heat of the refrigerant to the outside air); a first pressure regulator 167 for reducing the pressure of the refrigerant having passed through the first condenser 163; and a first evaporator 161 for evaporating the refrigerant having passed through the first pressure regulator 167 by absorbing heat from the inside air of the storage chamber 12. A plurality of heat radiating panels fixed to the first refrigerant pipe 169 may be provided as the first condenser 163 and the first evaporator 161.

The first evaporator 161 must be configured to exchange heat with the inside air of the storage chamber 12 so that the chamber 14 may be further provided in the first housing 11. The first evaporator 161 may be installed in the chamber 14.

The chamber 14 may be provided in a wall defining the storage chamber 12, and a chamber inlet hole 141 and a chamber outlet hole 143 may be provided in the wall of the storage chamber to communicate the storage chamber 12 and the chamber 14 with each other. Fig. 2 illustrates that the chamber inlet hole 141 and the chamber outlet hole 143 are provided as holes penetrating the wall of the storage compartment as one example.

In addition, a first fan 164 may be further provided in the compartment 14 to re-discharge the inside air of the storage compartment 12 to the storage compartment 12 after the inside air passes through the compartment inlet hole 141, the first evaporator 161, and the compartment outlet hole 143 in sequence.

A first control unit 71 for controlling the first cooling unit 16 is provided in the first PCB (7, first printed circuit board). As shown in fig. 1, the first PCB7 is mounted in a first mounting unit 112 provided in the top surface 11b of the first chassis.

The first mounting unit 112 may be provided as a groove recessed from the top surface 11b of the first cabinet toward the storage chamber 12 (in other words, a groove recessed toward a direction to be guided farther away from the air treatment apparatus). The first mounting unit 112 may be opened and closed by a mounting unit cover 113, and the mounting unit cover 113 may be fastened to the top surface of the first chassis by using fastening members such as bolts.

The first PCB7 may include a first PCB first slot 73 and a first PCB second slot 75. The first PCB first slot 73 serves as a means for detachably securing the control line of the first compressor 165 to the first PCB7, and the first PCB second slot 75 serves as a means for detachably securing the control line of the first pressure regulator 167 to the first PCB 7.

The first compressor 165 may include a motor that is driven to rotate a roller or scroll (in other words, a first compressor motor). The control line of the first compressor motor is connected to the first control unit 71 via the first PCB first slot 73.

Further, the first pressure regulator 167 includes a valve driving unit (e.g., a solenoid valve) configured to adjust the cross section of the first refrigerant pipe 169. The control line of the valve driving unit is connected with the first control unit 71 via the first PCB second slot 75.

If a power module (not shown) of a refrigerator is provided to supply power to the first compressor 165 and the first pressure regulator 167 via the first PCB7, the first PCB first groove 73 may serve as a means for fixing a power line of the first compressor motor, and the first PCB second groove 75 may serve as a means for fixing a power line of a valve driving unit provided in the first pressure regulator to the first PCB.

Although not shown in the drawings, as an alternative example, the first PCB first slot 73 may serve as a means for fixing power and control lines of the first compressor 165 to the first PCB, and the first PCB second slot 75 may serve as a means for fixing power and control lines of the first pressure regulator 167 to the first PCB.

A first PCB third slot 77 for detachably connecting at least one of power lines and control lines of the first fan 165 may also be provided in the first PCB 7. The first fan 164 may be composed of a motor and an impeller that can be rotated by the motor. The motor may be supplied with power by the power module of the refrigerator via the first PCB third slot 77, and receive a control signal regarding the number or direction of rotations transmitted by the first control unit 71 via the first PCB third slot 77.

A first control panel 151 may be provided in the first door 15. The first control panel 151 may include: a first input unit 152 for receiving an input control command necessary for controlling the refrigerator; and a first display unit 153 for displaying execution information of a control signal that can be selected by a user or a control command selected by the user.

The first PCB7 may further include a first PCB fourth slot 79 for detachably fixing at least one of power lines and control lines of the first control panel 151.

When the power lines and the control lines of the first control panel 151 are connected with the first control unit 71 and the power module of the refrigerator via the first PCB fourth slot 79, the first input unit 152 and the first display unit 153 may be supplied with power by the power module of the refrigerator via the first PCB fourth slot 79. In addition, the first control unit 71 may receive a control signal transmitted from the first input unit 152 via the first PCB fourth slot 79, and the first display unit 153 may receive a control signal transmitted by the first control unit 71.

The reason why the plurality of grooves 73, 75, 77, and 79 are provided in the first PCB7 is to facilitate repair and maintenance of the refrigerator 100 according to the present disclosure. In other words, since the air treatment apparatus 5 can be fixedly mounted to the top surface 11a of the refrigerator 1, it is preferable that the first PCB7 including the first control unit 71 is disposed in an area accessible even without detaching the air treatment apparatus 5 from the refrigerator 1 in view of inspecting or repairing the refrigerator. To achieve the effect that the position of the first PCB7 is easily changed, grooves 73, 75, 77, and 79 are provided in the first PCB 7. Accordingly, the first PCB7 fixedly mounted to the top surface of the first cabinet can be moved and mounted in the air processing device 5, which will be described in detail later.

The air processing apparatus 5 provided in the refrigerator 100 according to the present disclosure may be provided as an air cleaner configured to remove dust, bacteria, or odor contained in indoor air by filtering the indoor air or an air conditioner configured to reduce humidity and temperature of the indoor air. Fig. 2 illustrates that the air processing device 5 is an air cleaner, and fig. 5 illustrates that the air processing device 5 is an air conditioner.

The air treatment device 5 shown in fig. 2 may include: a second housing 51 detachably mounted to the top surface 11b of the first housing 11; an inlet hole 517 and an outlet hole 516 for making the inside of the second housing 51 communicate with the outside; a blower fan 57 provided in the second housing 51 and configured to blow air sucked through the inlet hole 517 toward the outlet hole 516; and a filter unit 56 for filtering air sucked into the second cabinet 51.

The second housing 51 may be provided in any shape. The second housing 51 shown in fig. 2 may include a front surface 51a, a rear surface 51d, an upper surface 51b, and two side surfaces 51c and a lower surface 51 e. The front surface 51a of the second cabinet is disposed in a direction in which the first door 15 of the refrigerator is located, and two side surfaces 51c are disposed to connect the front and rear surfaces to each other. The lower surface 51e is disposed in a direction toward the top surface 11a of the refrigerator.

In this case, the inlet hole 517 may be provided as a plurality of through holes penetrating the upper surface 51b of the second housing, and the outlet hole 516 may be provided as a plurality of through holes penetrating the front surface 51a of the second housing.

A baffle 516a for controlling the flow direction of the discharged air may be further provided in the outlet hole 516. As shown in the drawing, the baffle 516a may be a plurality of plates arranged in parallel with the width direction of the outlet hole 516 to adjust the vertical outlet angle of the air. As another alternative example, the baffle 516a may be a plurality of plates arranged in parallel with the height direction of the outlet hole 516 to adjust the horizontal outlet angle of the air.

The blower 57 is provided in the duct 54 for guiding the air sucked through the inlet hole 517 toward the outlet hole 516. The conduit 54 may include: a partition wall 541 for dividing an inner space of the second housing 51 into several spaces; a first side wall 543 and a second side wall (not shown) which are provided in both end portions of the partition wall so as to face each other; and an upper wall 545 fixed to upper ends of the first and second sidewalls to be spaced apart from the partition wall 541 by a predetermined distance.

The upper wall 545, the first side wall and the second side wall extend from the outlet hole 516 toward the inside of the upper surface 51b of the second housing. Unlike the partition wall 541, they are not connected to the upper surface 51b of the second housing.

The blower 57 may include an impeller 571 disposed in the inlet of the duct and a motor 573 for rotating the impeller. The conduit inlet may be an open surface defined by the free end of the upper wall 545, the free end of the first side wall 543 and the free end of the second side wall.

The filter unit 56 may be provided at any position as long as it can filter the air drawn into the second housing 51. In other words, the filter unit 56 may be located between the inlet hole 517 and the impeller 571, and filter air to be supplied to the impeller 571. Alternatively, the filter unit may be located between the impeller 571 and the outlet hole 516, and filter the air that has passed through the impeller. Fig. 2 illustrates that the filter unit 56 is located between the inlet hole 517 and the impeller 571, as an example.

Accordingly, when the impeller 571 is rotated by the motor 573, external air may be drawn into the second housing 51 through the inlet hole 517, and the drawn air is discharged to the outside of the second housing through the duct inlet and outlet holes 516. The air passes through the filter unit 56 during this process so that dust or smell contained in the indoor air can be filtered and removed by the filter unit 56.

A second control unit 91 for controlling the blower fan 57 may be provided in the second PCB (9, second printed circuit board). The second PCB 9 may include a second PCB first slot 93, the second PCB first slot 93 for detachably securing a control cord of a motor 573 provided in the blower 57 to facilitate assembly of the air treatment device 5 and inspection or repair of the air treatment device 5.

In this case, the control line of the motor 573 is connected with the second control unit 91 via the second PCB first slot 93. If a power module (not shown) of the air treatment apparatus is provided to supply power to the motor 573 via the second PCB 9, the second PCB first slot 93 may serve as a means for fixing the power lines of the motor 573 to the second PCB.

Further, the second PCB 9 may be mounted in a second mounting unit 518 provided in one of the side surface 51c and the rear surface 51 d. Fig. 2 illustrates that the second mounting unit 518 is provided in the rear surface 51d of the second housing.

Considering that the air treatment apparatus 5 is mounted to the refrigerator 1 having the first PCB7 fixed to the top surface 11b of the first cabinet, the second mounting unit 518 may be provided in a preset size and shape that can accommodate both the first PCB7 and the second PCB 9. In other words, the second mounting unit 518 may serve as a means capable of changing the position of the first PCB7 in a case where the user mounts the air treatment apparatus 5 on the top surface of the refrigerator 1 after purchasing only the air treatment apparatus 5 or the manufacturer mounts the air treatment apparatus 5 on the top surface 11b of the first cabinet to which the first PCB7 is fixed.

Therefore, when the air treatment apparatus 5 is mounted on the top surface 11b of the refrigerator 1, the worker removes the power and control lines fixed to the slots 73, 75, 77, and 79 of the first PCB and removes the first PCB7 from the refrigerator. Accordingly, the worker may move the first PCB7 to the second mounting unit 518 and then reconnect the power lines and the control lines of the first control panel 151 and the first cooling unit 16 to the slots 73, 75, 77, and 79 of the first PCB7, respectively.

In addition, in order to prevent damage to the first and second PCBs 7 and 9, the second mounting unit 518 shown in fig. 3 may be opened and closed by the cover 516.

The filter unit 56 may be detachably provided in the second housing 51 to facilitate cleaning of the filter unit 56. For this reason, a filter mounting unit 55 may be further provided in the second cabinet to provide a predetermined space for accommodating the filter unit 56.

In order for the user to easily detach or detach the filter unit 56 from the filter mounting unit 55, the filter unit 56 may be drawn out from the front surface 51a of the second cabinet. For this, a filter opening 511 is provided in the front surface 51a of the second cabinet, and the filter mounting unit 55 communicates with the filter opening 511. The filter opening 511 may be opened and closed by a second door rotatably coupled to the second cabinet 51.

A second control panel 513 may be provided in the second door 512. The second control panel 513 may include at least one of a second input unit 514 and a second display unit 515. The second input unit 514 may be a means for receiving user input of control commands necessary for controlling the air treatment device 5, and the second display unit 515 may be a means for displaying control commands that can be selected by the user or execution information of the control commands selected by the user.

The second PCB 9 may further include a second PCB fifth slot 99 for detachably fixing at least one of power lines and control lines of the second control panel 513.

When the power lines and control lines of the second control panel 513 are connected with the second control unit 91 and the power module of the air treatment device via the second PCB fifth slot 99, the second input unit 514 and the second display unit 515 may be supplied with power by the power module of the air treatment device via the second PCB fifth slot 99. The second control unit 91 may receive the control signal transmitted from the second input unit 514 via the second PCB fifth slot 99, and the second display unit 515 may receive the control signal transmitted by the second control unit 91 via the second PCB fifth slot 99.

It is more advantageous to dispose the filter opening 511 at a lower position in consideration of relatively short user convenience. It is more advantageous to provide the filter unit 56 with a larger area in view of the cleaning period of the filter unit 56. Therefore, it is preferable that the filter mounting unit 55 is inclined downward toward the filter opening 511. In other words, one end of the filter mounting unit 55 may be fixed to the front surface 51a of the second cabinet and can communicate with the filter opening 511. The other end of the filter mounting unit 55 may be fixed to the upper surface 51b of the second cabinet. In this case, the inlet hole 517 may be located in a space above the filter mounting unit 55, and the space is defined by the upper surface 51b of the second cabinet.

In consideration of the user-friendliness of a short-sized user, the filter mounting unit 55 may include: a first mounting body 551 fixed to the second housing 51; a second mounting body 555 defining a space for receiving the filter unit 56 and capable of being withdrawn from the first mounting body 551; and a connection portion 556 for preventing the second mounting body 555 withdrawn from the first mounting body 551 from being separated from the second housing 51.

The first mounting body 551 may be provided in any shape only when the second mounting body 555 can be received. Fig. 3 illustrates that the first mounting body 551 is provided in a hexahedral shape.

An insertion hole into which the second mounting body 555 is inserted is provided in one surface of the first mounting body 551. A first communication hole 552 and a second communication hole 553 are respectively provided in the upper and lower surfaces of the first mounting body 551 while penetrating the first mounting body.

The second mounting body 555 may be provided in any shape only when the filter unit 56 can be received and withdrawn from the first mounting body 551. Fig. 4 illustrates that the second mounting body 555 is provided in a hexahedral shape with an inner space.

As shown in fig. 4, a filter insertion hole 555d is provided in the front surface of the second mounting body 555 and can communicate with the filter opening 511. Upper and lower opening holes 555a and 555b are provided in the upper and lower surfaces of the second mounting body 555, respectively, and can communicate with the first and second communication holes 552 and 553, respectively.

In addition, two side surface opening holes 555c may be further provided in both side surfaces of the second mounting unit, respectively, to rapidly discharge the air having passed through the filter unit 56 to the outside of the second mounting body 555. In this case, two side surface communication holes (not shown) communicating with the two side surface opening holes 555c may also be provided in both side surfaces of the first mounting body 551, respectively.

The connection portion 556 may serve as a means for facilitating a short-sized user to access the filter unit 56 by preventing the second mounting body 555 from being separated from the second cabinet 51 even when the second mounting body 555 is withdrawn from the first mounting body 551.

The connection portion 556 may include: a first guide groove (5561, see fig. 3) and a second guide groove, which are respectively provided in side surfaces of the first mounting body 551 facing each other and are formed along a withdrawal direction of the second mounting body 555; a first link 558 having one end rotatably connected to one side of the second mounting body 555 and the other end inserted into the first guide groove 5561; and a second link 559 having one end rotatably connected to the other side of the second mounting body 555 and the other end inserted into the second guide groove.

A first link coupling hole may be provided in one end of the first link 558 so that the first protrusion 5571 of the second mounting body 555 is inserted therein. The first link protrusion 5581 may be provided in the other end of the first link 558 to be inserted into the first guide groove 5561.

Similarly, a second link coupling hole may be provided in one end of the second link 559 such that the second protrusion 5573 of the second mounting body 555 is inserted therein. The second link protrusion 5591 may be provided in the other end of the second link 559 to be inserted into the second guide groove.

The filter unit 56 may include: a filter frame 561; a first filter 563 fixed to the filter frame and inserted into the second mounting body 555; and a second filter 565 fixed to a lower surface of the first filter and inserted into the second mounting body 555. Only when the filters 563 and 565 can be fixed, the filter frame 561 may be provided in various shapes.

The first filter 563 may be a filter capable of filtering relatively large foreign particles, and the second filter may be a filter capable of filtering relatively small foreign particles. For this reason, the diameter (first diameter) of the filter holes provided in the first filter 563 may be set larger than the diameter (second diameter) of the filter holes provided in the second filter 565.

In addition, the filter unit 56 may further include a third filter 567, the third filter 567 being fixed to a lower surface of the second filter 565 and inserted into the second mounting body 555. The third filter 567 may be configured to filter the odor particles.

Fig. 5 illustrates the air processing apparatus 5 as being provided as an air conditioner. In this embodiment, the air treatment apparatus 5 is characterized in that a second cooling unit 58 is further provided.

The second cooling unit 58 may include: a second refrigerant pipe 589 for forming a circulation path of the refrigerant; a second compressor 585 for circulating refrigerant along a second refrigerant pipe 589; a second condenser 583 for condensing the refrigerant by heat-exchanging the refrigerant discharged from the second compressor 585 with the outside air of the second cabinet 51; a second pressure regulator 587 for reducing the pressure of the refrigerant having passed through the second condenser 583; and a second evaporator 581 for evaporating refrigerant having passed through the second pressure regulator 587 by absorbing heat from air in the suction inlet hole 517.

A plurality of heat dissipation panels fixed to the second refrigerant pipe 589 may be provided as the second condenser 583 and the second evaporator 581. The second evaporator 581 may be disposed between the filter unit 56 and the impeller 571, and the second condenser 583 may be fixed to the outside of the second cabinet 51.

In order to facilitate heat exchange between the refrigerant and the air passing through the second condenser 583, the second cooling unit 58 may further include a second fan 584 for blowing the air toward the second condenser 583.

The second cooling unit 58 may be controlled by a second control unit 91 provided in the second PCB 9 described above. In other words, the second compressor 585, the second pressure regulator 587, and the second fan 584 may be controlled by the second control unit 91.

In this case, the second PCB 9 may further include: a second PCB second slot 95 for detachably connecting at least one of power lines and control lines of a motor provided in the second compressor 585 with the second PCB 9; a second PCB third groove 97 for detachably connecting at least one of power lines and control lines of a valve driving unit provided in the second pressure regulator 587 with the second PCB 9; and a second PCB fourth slot 98 for detachably connecting at least one of power lines and control lines of the motor provided in the second fan 584.

The other elements except the above-mentioned second cooling unit 58 are identical to the corresponding elements of the air treatment apparatus 5 mentioned above with reference to fig. 2 to 4, and thus a detailed description is omitted.

As the present features may be embodied in several forms without departing from the characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
