Indoor unit of air conditioner
Technical Field
The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner in which a display unit is disposed.
Background
An indoor unit of an air conditioner can adjust a desired indoor temperature by discharging air, which exchanges heat with a refrigerant, into a room. An indoor unit of an air conditioner can suck indoor air through an inlet, exchange heat with refrigerant, and discharge the heat-exchanged air through an outlet.
Indoor units of air conditioners may be classified into a ceiling type, a wall-hung type, and an upright type according to installation locations. In the upright type indoor unit, the discharge port may be formed toward the front or side of the cabinet, and the suction port may be formed toward the rear of the cabinet.
The upright type indoor unit is disposed facing an indoor space on one side of the indoor space, and the front surface thereof is disposed facing the indoor space. Accordingly, a display for providing visual information to a user and a proximity sensor for detecting a distance of the user may be provided at a front surface of the indoor unit.
In order to provide the display and the proximity sensor to the indoor unit, a hole for exposing the display and a hole for detecting the proximity sensor need to be provided on the front surface of the indoor unit. Since the display and the proximity sensor perform different functions from each other, a space for disposing the display and a space for disposing the proximity sensor may be separately formed at the front surface of the indoor unit, respectively.
In such a configuration, an additional hole or space for installing the display and the proximity sensor needs to be provided, and the display and the proximity sensor need to be separately installed when the display and the proximity sensor are installed, which causes a problem of complicated manufacturing process.
Korean granted patent KR 10-1940534 discloses a vertical type indoor unit and discloses a display and a proximity sensor disposed in a spaced manner in front of the indoor unit.
In order to solve the above-described problems, a configuration may be conceivable in which the display and the proximity sensor are disposed in the same space, but this may cause a problem in that the proximity sensor and the display interfere with each other.
Further, when a touch panel is attached to the display to add a touch function to the display, the proximity sensor may be damaged or malfunction due to pressure applied to the display.
Disclosure of Invention
A first object of the present invention is to provide an indoor unit of an air conditioner, which can easily manufacture an indoor unit mounted with a display and a proximity sensor.
A second object of the present invention is to provide an indoor unit of an air conditioner, which can maximize the use of space of the indoor unit to which a display and a proximity sensor are attached.
In order to solve the first and second objects described above, the display and the proximity sensor may be disposed in the same space. However, when a touch panel is mounted to realize a touch sensor function in a display, a problem may occur in that the proximity sensor is damaged or misoperated due to pressure such as a touch of a user. A third object of the present invention is to provide an indoor unit of an air conditioner that solves the above-described problems.
The object of the present invention is not limited to the above-mentioned object, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.
In order to achieve the above object, an indoor unit of an air conditioner according to the present invention includes: the cabinet body assembly is formed into an appearance, and the front surface of the cabinet body assembly is open; a door panel covering an open front surface of the cabinet assembly and having a display hole formed in an open manner along a front-rear direction; the display module is configured in the display hole and used for displaying the working state of the indoor unit; the display module includes: a display to provide visual information to a user; the display is arranged on the display shell, and the position of the display is fixed behind the door panel; a front glass disposed in front of the display and covering the front of the display module; a proximity sensor disposed behind the front glass and measuring a distance of a user positioned in front of the door panel; and a rear cover having a proximity sensor hole for disposing the proximity sensor formed at one end thereof, the rear cover being disposed between the front glass and the display to maintain a space for disposing the proximity sensor. Thus, the display and the proximity sensor can be disposed in the same space, and a space for disposing the proximity sensor can be secured in the rear cover.
The front glass includes: a first printing portion formed on a rear surface of the front glass and printed along an edge portion of the front glass; a second printing portion formed on a rear surface of the front glass and performing printing at a predetermined interval from the first printing portion to an inner side in a radial direction; and a sensor exposure portion located between the first printing portion and the second printing portion, the sensor exposure portion being unprinted. This makes it possible to easily confirm the region where the front glass and the rear cover are joined.
The proximity sensor is disposed behind the sensor exposure portion. This makes it possible to leave the front of the proximity sensor unclosed, and to prevent the appearance of the display module in which the proximity sensor is disposed from being affected.
The rear cover includes a rear cover printing portion that prints from a front surface of the rear cover along an edge portion, the rear cover printing portion printing from an outer circumferential end of the rear cover to a position corresponding to an inner end portion of the second printing portion. Thus, the position where the front glass and the rear cover are joined to each other can be clearly defined, and the area where the proximity sensor is disposed can be secured.
The proximity sensor hole is formed from an upper end of the rear cover to an inner end of the rear cover printing part. This ensures an area where the proximity sensor is disposed.
The interval between the first printing portion and the second printing portion is greater than or equal to the length of the proximity sensor formed along the vertical direction. Thus, the sensor exposure portion for the proximity sensor can be formed within a range that does not affect the aesthetic appearance of the front surface.
The display module includes: a proximity sensor circuit board receiving the recognized signal transmitted from the proximity sensor; and a reflection plate disposed at a periphery of the proximity sensor, and securing a space of the proximity sensor disposed between the front glass and the proximity sensor circuit board. This can protect the proximity sensor from external impact.
The reflecting plate has a quadrangular ring shape, and is disposed on the periphery of the proximity sensor in the proximity sensor hole. This can protect the proximity sensor from external impact.
The proximity sensor circuit board extends from the rear side of the proximity sensor to the upper side and is fastened to the display housing. This enables the proximity sensor to be fixedly disposed.
The display housing includes: and a display mounting part formed to be recessed rearward to mount the display. This enables stable arrangement of the display.
The display module further includes: and a touch panel disposed between the display and the rear cover, for receiving a user's instruction. Thus, the display module can realize a touch function.
The touch panel includes a first hole forming a space for disposing the proximity sensor behind the proximity sensor hole formed at the rear cover. This can ensure a space for disposing the proximity sensor in the structure of the touch panel.
The display housing includes: a touch panel mounting portion formed in front of the display mounting portion, a part of the touch panel being inserted into the touch panel mounting portion; and a touch panel fixing portion formed to protrude forward from an upper side of the touch panel mounting portion, for fixing an arrangement of the touch panel. This enables the touch panel to be fixed to the display housing.
The display module further includes a remote control reception sensor that receives a signal input from an external remote control transmitter, a remote control reception sensor hole is formed in the rear cover, and the remote control reception sensor is disposed in the remote control reception sensor hole behind the front glass. Thus, the remote control reception sensor can be arranged in the display module.
The invention also includes: an inner panel disposed behind the door panel, the inner panel covering the exposed front surface of the cabinet assembly when the door panel moves in a left or right direction in front of the cabinet assembly; a discharge port cover which is disposed behind the door panel so as to be movable in the vertical direction and opens and closes a front discharge port formed in the door panel; and a spout cap moving module for moving the spout cap in an up-and-down direction; the discharge port cover is disposed between the display module and the inner panel when the discharge port cover moves to a lower side of the front discharge port to open the front discharge port. This ensures a space between the door panel and the inner panel in which the spout cover can be moved.
The spit-out port cover includes: a door cover for opening and closing the discharge port cover; a door cover housing forming a space for accommodating at least a part of the door cover, connected with the spout cover moving module, to adjust the up-down position of the door cover; and a door cover moving module disposed between the door cover housing and the door cover, and configured to move the door cover in a front-rear direction from the door cover housing. Thereby, the door cover of the discharge port cover can be moved in the front-rear direction.
When the discharge port cover is disposed between the display module and the inner panel, a gap between the display module and the door cover of the discharge port cover is formed to be larger than a gap between the door cover housing of the discharge port cover and the inner panel. Thus, the spout cover can be moved without contacting the display module.
Additional embodiments are specifically included in the detailed description and the accompanying drawings.
The indoor unit of an air conditioner according to the present invention has one or more of the following effects.
First, the proximity sensor and the display are disposed in the same space. That is, since the display and the proximity sensor are disposed in the display hole of the door panel, and the proximity sensor and the display are disposed together in the display hole without forming a plurality of holes in the door panel, the manufacturing process is easy and the time required for the process can be shortened as compared with a structure in which the proximity sensor and the display are mounted in an additional region.
The second proximity sensor, the proximity sensor and the display are disposed in the same space. That is, since the proximity sensor is disposed in the area where the display is disposed, it is not necessary to provide an additional space for disposing the proximity sensor, and therefore, the space utilization rate inside the indoor unit is high.
Third, the proximity sensor has a structure in which a proximity sensor hole disposed in the rear cover and a first hole of the touch panel are provided, and a reflection plate is disposed around the proximity sensor. Thus, even if pressure is applied to the display by the user for touching, the impact applied to the proximity sensor can be minimized, and the life span of the proximity sensor can be extended.
Fourth, the first printing portion, the second printing portion, and the rear cover printing portion are formed at the contact surface of the front glass and the rear cover, so that the coupling precision of the front glass and the rear cover can be improved. In addition, the proximity sensor is used without affecting the appearance of the portion exposed forward by exposing only the area where printing is performed to the outside except the area where the proximity sensor is disposed.
The effects of the present invention are not limited to the above-mentioned objects, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

The front discharge port 211a is formed in a circular shape. The front discharge port 211a has a shape corresponding to the front shape of the discharge grill 311. The discharge grill 311 hidden in the cabinet assembly i is exposed to the outside through the front discharge port 211 a.
When the front discharge port 211a is opened, the front air blower module 31 moves in the direction of the front discharge port 211a, and the discharge grill 311 can penetrate the front discharge port 211a and project forward beyond the door panel 21.
The first side surface portion 212a protrudes rearward from the left edge of the front surface portion 211, and covers the left surfaces of the upper panel 23 and the lower panel 24 fixed to the back surface of the front surface portion 211.
The second side surface part 212b protrudes rearward from the right edge of the front surface part 211, and covers the right side surfaces of the upper panel 23 and the lower panel 24 fixed to the back surface of the front surface part 211. The first side surface portion 212a and the second side surface portion 212b are exposed to the outside from the side surface where the upper panel 23 and the lower panel 24 are cut.
In the present embodiment, the front surface portion 211, the first side surface portion 212a, and the second side surface portion 212b constituting the door panel 21 may be integrally formed. In the present embodiment, the door panel 21 may be entirely made of a metal material. In particular, the door panel 21 may be formed entirely of an aluminum material.
A first curved portion 212a1 and a second curved portion 212b1 that are perpendicularly bent in the center direction of the door panel are formed at the end portions of the first side surface portion 212a and the second side surface portion 212b, respectively. The upper panel 23 and the lower panel 24 may be disposed inside the front portion 211 and inside each of the first curved portion 212a1 and the second curved portion 212b 1.
Thus, the front surface portion 211, the first side surface portion 212a, the second side surface portion 212b, the first curved portion 212a1, and the second curved portion 212b1 form an insertion space 213 into which the upper panel 23 and the lower panel 24 are inserted behind the front surface portion 211. The upper panel 23 and the lower panel 24 can be fixed and arranged by being clamped in an insertion space 213 formed behind the front surface 211.
The upper panel 23 and the lower panel 24 may be separately manufactured, the upper panel 23 being inserted into the door panel 21 from the upper side of the door panel 21, and the lower panel 24 being inserted into the door panel 21 from the lower side of the door panel 21.
The upper panel 23 and the lower panel 24 are inserted into and fixed to the insertion space 213 of the door panel 21, and are used to support the door panel 21 and prevent deformation and bending of the door panel 21.
In the present embodiment, the upper panel 23 and the lower panel 24 can support the front surface portion 211, the first side surface portion 212a, and the second side surface portion 212b to which external impacts are frequently applied.
The top panel 23 has a plate shape and is disposed on the back surface of the door panel 21. The upper panel 23 is formed with a panel discharge port 23a, and the panel discharge port 23a penetrates in the front-rear direction of the upper panel 23 and is positioned behind the front discharge port 211a so as to communicate with the front discharge port 211 a.
The panel discharge port 23a corresponds to the front discharge port 211 a. The front discharge port 211a is located forward of the panel discharge port 23 a. In the present embodiment, the panel discharge port 23a and the front discharge port 211a are both formed in a circular shape. In order to prevent the discharge air from leaking, a gasket (not shown) may be disposed between the panel discharge port 23a and the front discharge port 211 a.
The area of the panel discharge port 23a may be the same as the area of the front discharge port 211a or may be larger than the area of the front discharge port 211 a. In the present embodiment, the panel discharge port 23a may be formed slightly larger than the diameter of the front discharge port 211a in consideration of the installation of the gasket.
The discharge grill 311 of the front blower module 31 passes through the panel discharge port 23a and the front discharge port 211a in this order, and the discharge grill 311 protrudes forward from the front surface of the door panel 21.
In the present embodiment, the discharge port cover 25 and the display module 29 are provided on the upper panel 23.
The upper panel 23 can be attached to the door panel 21 in a state where both the spout cover 25 and the display module 29 are incorporated in the upper panel 23.
The upper panel 23 includes a display module mounting portion 232 for mounting the display module 29 therein. The display module mounting portion 232 is used to mount a display housing 291 of a display module 29 to be described below. The display module mounting part 232 formed on the upper panel 23 may be formed with a hole having a shape corresponding to the display module housing 291. The display module mounting part 232 may include a fastening part (not shown) fastened to the display housing 291 using an additional fastening member (not shown).
The display module 29 is fixed to the display module mounting portion 232 of the upper panel 23 by the display housing 291. The case where the display module 29 protrudes forward from the upper panel 23 is minimized by the display housing 291.
The display enclosure 291 may be disposed to penetrate the upper panel 23 in the front-rear direction.
In the state of being assembled to the upper panel 23, a part of the display module 29 is exposed to the outside through the display hole 211b of the door panel 21. The display module 29 may form a continuous surface with the front surface of the door panel 21 in a state where the display module 29 is exposed to the outside through the display hole 211 b.
That is, the front surface of the front glass 292 disposed in front of the display module 29 may be a continuous plane with the front surface of the door panel 21, rather than protruding forward beyond the door panel 21.
The display module 29 transmits and receives power and electric signals through a cable penetrating the upper panel 23.
The discharge port cover 25 may be disposed on the back surface of the top panel 23 and may move in the vertical direction along the back surface of the top panel 23.
After the discharge port cover 25 opens the front discharge port 211a, the discharge port cover 25 may be positioned at the same height as the display module 29 when the discharge port cover 25 is moved downward.
The discharge port cover 25 is disposed to be movable in the vertical direction with respect to the upper panel 23.
In the present embodiment, the upper panel 23 and the lower panel 24 are stacked in the vertical direction. In particular, since the upper panel 23 and the lower panel 24 are assembled with each other inside the door panel 21, generation of sloshing or running noise is minimized when the door assembly ii is slidingly moved.
Therefore, the upper panel 23 and the lower panel 24 can be assembled by interference fit. One of the upper and lower panels 23 and 24 is formed with a panel protrusion protruding toward the opposite side, and the remaining one is formed with a panel clamping portion 241 for receiving the panel protrusion.
In the present embodiment, the panel protrusion 233 is formed on the upper panel 23. The panel protrusion 233 protrudes downward at the lower end of the upper panel 23.
The lower panel 24 is provided on the back surface of the door panel 21. The lower panel 24 is provided in the insertion space 213 of the door panel 21. The lower panel 24 is located at a lower side of the upper panel 23 to support the upper panel 23 and is assembled with the upper panel 23.
The lower panel 24 is provided in the door panel 21 to prevent deformation of the door panel 21. The lower panel 24 is combined with the upper panel 23 in an interference fit manner and supports the upper panel 23 at the lower side of the upper panel 23.
A panel clamping portion 241, which is clamped and combined with the panel protrusion 233 of the upper panel 23, is formed at the upper side of the lower panel 24. The panel clamping portion 241 is formed to be recessed downward.
The lower panel 24 is provided with a door driving unit 282.
An indoor unit of an air conditioner according to an embodiment of the present invention may include: the upper end position sensor 235a and the lower end position sensor 235b are disposed on the inner surface of the door panel 21, and detect the movement of the discharge port cover 25.
For example, the infrared IR transmitting/receiving modules of the upper end position sensor 235a and the lower end position sensor 235b are respectively located at a movement start point (highest point) and a movement end point (lowest point) of the spout cover 25, so that the position of the spout cover 25 can be detected.
In the normal operation, the discharge port cover 25 may be detected by one of the upper end position sensor 235a and the lower end position sensor 235 b.
For example, the spout cover 25 in the closed state may be detected by the upper end position sensor 235a, and the spout cover 25 in the open state may be detected by the lower end position sensor 235 b.
The control unit 800 may confirm the initial position of the discharge port cover 25 and move the discharge port cover 25 to the opposite position in response to the product opening/closing operation command.
When the spout cover moving module 26 moves from the initial position to the opposite position, if the detection sensor of the opposite position starts detecting, the control unit 800, which will be described below, may cause the spout cover moving module 26 to perform the deceleration operation.
When the discharge port cover 25 reaches the target point (the highest point or the lowest point), the control unit 800 may control the discharge port cover 25 to stop.
In addition, even if the discharge port cover 25 is not at the accurate initial position, if the discharge port cover 25 is detected by the upper end position sensor 235a or the lower end position sensor 235b, the control unit 800 may control the movement of the discharge port cover 25 based on the position information of the discharge port cover 25.
However, an abnormal operation condition in which the discharge port cover 25 cannot be detected by both the sensors 235a and 235b may occur between the upper end position sensor 235a and the lower end position sensor 235 b.
For example, if the power supply line is turned off or a power failure occurs when the discharge port cover 25 is located in the intermediate position area between the upper end position sensor 235a and the lower end position sensor 235b, such an abnormal operation condition may occur.
The control unit 800 may control the compensation operation when the abnormal operation condition occurs.
The control unit 800 may perform the initialization compensation operation by the closing operation so that the upper end position sensor 235a can detect the discharge port cover 25.
In this case, the control unit 800 may control the discharge port cover moving module 26 to operate in the maximum (Max) step (step).
Subsequently, when the discharge port cover 25 is detected from the upper end position sensor 235a, the control section 800 may control the discharge port cover 25 based on the detected position information.
Alternatively, if the discharge port cover 25 is not detected from the upper end position sensor 235a, the control unit 800 may unconditionally stop the discharge port cover 25 and respond with a sensor failure mode. In the sensor failure mode, the control part 800 may control the audio output part 840 and/or the display module 29 to be able to output a message for prompting a sensor failure.
< door Assembly-spout cover >
The discharge port cover 25 is configured to open and close the front discharge port 211a disposed in the door assembly ii.
The discharge port cover 25 expands the movement path of the front air blower module 31 by opening the front discharge port 211 a. The front blowing module 31 may protrude to the outside of the door assembly ii through the opened front discharge port 211 a.
The discharge port cover 25 is positioned on the moving path of the front blower module 31. When the front discharge port 211a is opened, the discharge port cover 25 moves out of the path of movement of the front blower module 31.
The discharge port cover 25 includes: a door 251 disposed at the front discharge port 211a and moving in the front-rear direction of the front discharge port 211a to open and close the front discharge port 211 a; a door cover housing 253 forming a space for accommodating at least a portion of the door cover 251, for adjusting the up-down position of the door cover 251; and a door cover moving module 252 disposed between the door cover case 253 and the door cover 251, for moving the door cover 251 from the door cover case 253 in the front-rear direction.
The door cover 251 is inserted into the front discharge port 211a and provides a surface continuous with the front surface 211 of the door panel 21. The door cover 251 can be moved backward by the driving of the door cover moving module 252. After the door 251 is separated from the front discharge port 211a, the discharge port cover moving module 26 is driven to move the entire discharge port cover 25 downward.
When the door cover 251 is moved downward by the discharge port cover moving module 26, the front discharge port 211a is opened in the front-rear direction.
As shown in fig. 8, the state in which the door cover 251 is moved rearward from the forward discharge port 211a by the door cover moving module 252 and the door panel 21 and the door cover 251 are spaced apart in the forward and rearward directions is defined as the first front surface being open.
When the first front surface is open, the front air supply module 31 is shielded by the door cover 251 and is not exposed to the user.
When the first front surface is open, the front air supply module 31 is located behind the door cover 251. When the first front surface is open, the door 251 is located at a position further rearward than the front surface 211.
As shown in fig. 10, a state in which the door cover 251 is moved from behind the front discharge port 211a to below the front discharge port 211a by the discharge port cover moving module 26 and the front discharge port 211a is not blocked by the door cover 251 is defined as a second front surface being open.
When the second front surface is open, the door 251 is positioned below the front discharge port 211a and the front blower module 31. When the second front surface is open, the door 251 is located at a position further rearward than the front surface 211.
When the second front surface is open, the front air blowing module 31 is exposed to the user through the front discharge port 211 a. When the second front surface is open, the front air blowing module 31 moves forward and can project outward toward the front discharge port 211a, and air can be discharged toward the interior in a state where the front air blowing module 31 projects outward toward the door panel 21.
When in the second front face open, at least one of the door cover housing 253 or the door cover 251 is located behind the display module 29. When the second front surface is open, the door cover 251 does not interfere with the display 295 even if it moves downward. When the second front surface is open, the door 251 and the back surface of the display module 29 are spaced apart by a predetermined distance.
That is, in order to prevent interference between the door cover 251 and the display module 29 when the second front opening operation is performed, the door cover 251 may be moved rearward more than the thickness of the door panel 21 when the first front opening operation is performed.
The door cover 251 includes: an outer door 2511 forming a continuous surface with the door panel 21; an inner door 2512 coupled to a back surface of the outer door 2511, assembled with the door moving module 252, and moved in a front-rear direction by a driving force of the door moving module 252; the moving member 2513 is connected to the inner door 2512, and receives the driving force transmitted from the door moving module 252 by interference with the door moving module 252.
The moving member 2513 is assembled with a cover guide 2524 of the door cover moving module 252, which will be described later. The moving members 2513 interfere with each other when the cover guide 2524 rotates, and move the door cover 251 coupled to the moving members 2513 forward or backward.
The outer door 2511 has the same area and shape as the front discharge port 211 a.
The inner door 2512 is not limited to the area or shape of the front discharge port 211 a. In the present embodiment, the inner door 2512 is formed wider than the outer door 2511. The inner door 2512 may function as a stopper that restricts the forward movement of the outer door 2511.
When the outer door 2511 is inserted into the front discharge port 211a, the inner door 2512 is closely attached to the edge of the front discharge port 211 a.
In this embodiment, the front discharge port 211a and the outer door 2511 are formed in a circular shape having the same diameter and shape, and the inner door 2512 is formed in a circular shape having a larger diameter than the front discharge port 211 a. In particular, the outer edge of the inner door 2512 is formed flat in the vertical direction, and covers the boundary between the front discharge port 211a and the outer door 2511.
The outer door 2511 may be formed of the same material as the door panel 21. The entire outer door 2511 may be formed of an aluminum metal material. The outer door 2511 may be coated with a metal material only on the front surface thereof. When only the front surface is coated with a metal material, the load of the door 251 can be reduced, and the operation loads of the door moving module 252 and the spout cover moving module 26 can be reduced.
The outer door 2511 is formed to have the same thickness as the front surface 211, and when inserted into the front discharge port 211a, the outer door 2511 may be formed as a continuous surface with the front and rear surfaces of the front surface 211.
The inner door 2512 is closely attached to the back surface of the outer door 2511, is coupled to the back surface of the outer door 2511, and is formed to have a diameter wider than that of the outer door 2511.
The center of the inner door 2512 coincides with the center of the outer door 2511.
In the present embodiment, the inner door 2512 is formed in a disk shape. Unlike the present embodiment, the inner door 2512 may be formed in a ring shape having a space formed at the center thereof.
The inner door 2512 includes: a core door 25121(core door cover) positioned at the center of the inner door 2512 and closely attached to the back surface of the outer door 2511; a border door 25122(border door cover) located radially outward of the core door 25121 and closely attached to the outer edge of the outer door 2511; a connecting door 25123 for connecting the core door 25121 and the bezel door 25122; and a connecting rib 25124 for connecting the core door 25121, the connecting door 25123 and the bezel door 25122 and protruding from the connecting door 25123 toward the outer door 2511.
The connecting rib 25124 is disposed radially outward from the center of the inner door 2512. The plurality of the connecting ribs 25124 are arranged at equal angles with respect to the center of the inner door 2512.
The front surface of the connector rib 25124 may be snug against the back surface of the outer door 1212. The back surface of the connecting rib 25124 is integrally formed with the connecting door 25123. The inner side of the connecting rib 25124 is connected to the core door 25121 and the outer side is connected to the bezel door 25122.
When viewed from the front, the core door 25121 is formed in a circular shape, and the bezel door 25122 is formed in a ring shape.
The core door 25121 has a core opening 25121a into which a part of the structure of the door moving module 252 is inserted. Since a part of the structure of the door cover moving module 252 is inserted into the core opening 25121a, the thickness of the discharge port cover 25 in the front-rear direction can be minimized.
The bezel door 25122 is formed in parallel with the outer door 2511. The bezel door cover 25122 includes a bezel flange 25122a, and the bezel flange 25122a protrudes more outward than the outer edge of the outer door cover 2511.
Bezel flange 25122a is located at a position further to the rear side than inner door 2512. The bezel flange 25122a protrudes further to the outside in the radial direction than the inner door 2512.
In the present embodiment, the bezel flange 25122a is formed in a circular shape along the outer edge of the outer door 2511.
The thickness of the spout cover 25 occupies most of the thickness of the door assembly ii. Therefore, the thickness of the discharge port cover 25 in the front-rear direction is minimized, which is an important element for minimizing the thickness of the door assembly ii. If the thickness of the door assembly ii is minimized, the operational load of the door driving part 282 can be minimized.
The core opening 25121a penetrates the outer door 2511 in the front-rear direction. A motor of the door cover moving module 252 described later is inserted into the core opening 25121 a.
The moving member 2513 is disposed on the inner door 2512. The moving member 2513 may be integrally formed with the inner door 2512.
In the present embodiment, the moving member 2513 is separately manufactured and then assembled to the inner door 2512. Therefore, the moving member 2513 is provided with an assembly structure for assembly with the inner door 2512.
The moving member 2513 includes: a mover body 25131 protruding rearward from the inner door 2512; the moving element guide 25132 projects from the moving element main body 25131 inward or outward, and is inserted into a guide groove 25243(guide way) of a cap guide 2524, which will be described later.
The overall shape of the mover body 25131 is formed in a ring shape when viewed from the front.
The mover body 25131 is formed with a mover fastening portion 25133 fastened to the inner door 2512. The moving member fastening portion 25133 protrudes inward of the moving member main body 25131. The projecting direction of the moving member fastening portion 25133 is opposite to the projecting direction of the moving member guide 25132.
A fastening portion 25121b corresponding to the moving member fastening portion 25133 is formed on the inner door 2512. The fastening portion 25121b is formed to protrude toward the core opening portion 25121 a. The fastening portion 25121b is inserted into the moving member main body 25131.
A mover body holder 1233 for supporting the rear end of the core door 25121 is disposed on the inner peripheral surface of the mover body 25131.
The moving element body 25131 and the moving element guide 25132 are integrally formed. The mover body 25131 is arranged to protrude rearward from the door cover 251. The mover body 25131 extends to a length that can interfere with a cap guide 2524 described later.
In this embodiment, the moving member guide 25132 is orthogonal to the moving member body 25131. The moving member guide 25132 may be disposed in a direction parallel to the front surface 211.
The protruding direction of the moving member guide 25132 may be different according to the combination with the cap guide 2524. In the present embodiment, since the moving member main body 25131 is inserted inside the cap guide 2524, the moving member guide 25132 projects outward from the moving member main body 25131. Unlike the present embodiment, in the case where the mover body 25131 is located outside the cover guide 2524, the guide projection projects to the inside of the mover body 25131.
The moving element guide 25132 is assembled to a guide groove 25243 of a cap guide 2524, which will be described later, and when the cap guide 2524 rotates, the moving element guide 25132 can move forward or backward along the guide groove 25243.
In addition, the door housing 253 moves in the up-down direction along the upper panel 23.
The door housing 253 includes: a door housing body 2531 moving in the up-down direction along the upper panel 23; a door cover receiving portion 2532 which is disposed in the door cover housing body 2531, opens forward, and selectively receives the door cover 251; the movement module installation portion 2533 is disposed in the door cover housing main body 2531, is open to the front, communicates with the door cover housing portion 2532, is disposed at a position behind the door cover housing portion 2532, and is used to arrange a part of the structure of the door cover movement module 252.
The door housing 253 includes: and a guide rib 2536 for moving the door housing 253 along the upper panel 23. Further, a guide groove (not shown) may be formed in the upper panel 23 in the vertical direction to move the guide rib 2536. The guide rib 2536 can restrict the forward and backward movement of the spout cover 25 moving in the up-down direction.
The door case 253 is located in the insertion space 213 of the door panel 21.
The left and right sides of the door case 253 are positioned in front of the first bent portion 212a1 and the second bent portion 212b1, and the first bent portion 212a1 and the second bent portion 212b1 are locked to each other in the front-rear direction of the door case 253, thereby blocking the door case 253 from being separated rearward. The door housing 253 can slidably move in the up-down direction, and the movement in the front-rear direction thereof is restricted.
The door cover housing body 2531 is movable in the up-down direction along the insertion space 213 formed on the left and right sides of the door panel 21. The door housing body 2531 is moved in the vertical direction by the spout cover moving module 26.
The door housing body 2531 is formed to have a smaller thickness in the front-rear direction than the insertion space 213.
When the door cover moving module 252 operates, the door cover 251 can move to the rear side and is stored in the door cover storage portion 2532. When closing the front discharge port 211a, the door cover 251 is positioned further forward than the door cover case 253 and on the same plane as the door panel 21.
The door cover receiving portion 2532 is open in front to receive the door cover 251, and is formed in a circular shape when viewed from the front. The door cover receiving portion 2532 is formed to be recessed rearward from the door cover case 253.
The upper surface 2531a of the door case body 2531 is formed into a curved surface and is disposed so as to surround the edge of the door 251. The door cover 251 may be positioned at a lower side of the upper surface 2531 a. The door cover receiving portion 2532 is disposed below the upper surface 2531 a.
The center of curvature of the upper surface 2531a may coincide with the center of curvature of the door cover 251. The upper surface 2531a is located radially outward of the door cover 251.
Further, a door cover upper wall 231 is provided on the upper panel 23, and the door cover upper wall 231 interferes with the door cover case 253 and regulates the movement of the discharge port cover 25.
The door cover upper wall 231 projects rearward from the upper panel 23.
The door cover upper wall 231 may be formed in a shape corresponding to an upper side of the door cover housing 253. In the present embodiment, since the upper side of the door housing 253 is formed in an arc shape when viewed from the front, the door upper wall 231 is formed in an arc shape having a diameter larger than that of the door housing 253.
The door cover upper wall 231 is formed to surround the entire upper surface of the door cover housing 253. A door case 253 is closely attached to the lower surface of the door upper wall 231, and air leakage inside the cabinet can be cut off.
The flap upper wall 231 may form the same center of curvature as the panel discharge opening 23 a. The door cover upper wall 231 is formed with a larger radius of curvature than the panel discharge opening 23 a.
The door upper wall 231 can shut off the flow of the air inside the cabinet toward the camera module 22 side. In the case where the cool air of the cabinet assembly i is directly supplied to the camera module 22 side, dew condensation may occur in the camera module 22.
In order to restrict the movement of the discharge port cover 25 from the upper side, the door cover upper wall 231 is preferably located at a position higher than the panel discharge port 23 a.
When the discharge port cover 25 moves upward and the upper surface 2531a comes into contact with the door cover upper wall 231, the door cover 251, the panel discharge port 23a, and the front discharge port 211a are arranged in a row with respect to the front-rear direction. When the discharge port cover 25 is not lifted to the normal position, the door cover 251 is locked by the top panel 23 and cannot move to the front discharge port 211 a.
Each side surface 2531b of the door housing body 2531 is disposed so as to face the first side surface 212a and the second side surface 212b of the door panel 21. The side 2531b is located in the insertion space 213 of the door panel 21 and is movable in the up-down direction along the insertion space 213.
The moving module installation portion 2533 is formed to be recessed rearward from the door cover housing body 2531. The movement module installation portion 2533 communicates with the door cover storage portion 2532, and is located at a position rearward of the door cover storage portion 2532.
The movement module installation portion 2533 is opened in front and is formed in a circular shape when viewed from the front. The moving module installation portion 2533 is smaller in area than the door cover 251 and is located on the rear side of the door cover 251. The thickness of the moving module installation part 2533 in the front-rear direction is smaller than that of the door housing 253.
In the present embodiment, the moving module disposing part 2533 is formed in a circular shape when viewed from the front. The center of the moving module set portion 2533 coincides with the center of the door cover 251.
In addition, most of the structure of the door cover moving module 252 is provided in the moving module providing portion 2533.
The door cover moving module 252 moves the door cover 251 in the front-rear direction. The door cover moving module 252 is a structure for achieving the first front opening.
The door 251 may be moved in the front-rear direction by various methods. For example, the door cover 251 may be connected to an actuator such as a hydraulic cylinder and moved in the forward and backward directions by the piston movement of the hydraulic cylinder. As another example, the door cover 251 may be moved in a front-rear direction by a motor and a multi-link structure.
However, the structures such as the coupling structure and the hydraulic cylinder need to be provided with the structure that moves or rotates toward the front of the cabinet assembly i, and therefore, the thickness of the door assembly ii in the front-rear direction will inevitably increase.
In the present embodiment, the door cover moving module 252 changes the rotational force of the door cover motor by mutual interference, thereby moving the door cover 251 in the front-rear direction.
Such a structure of the door cover moving module 252 can minimize the front-rear direction thickness of the door assembly ii.
The door cover moving module 252 includes: a door cover motor 2521 located behind the door cover 251, provided in the door cover housing 253, and having a door cover motor shaft arranged in the front-rear direction; a sun gear 2522 shaft-coupled to the door cover motor and rotated by the operation of the door cover motor; a plurality of planetary gears 2523 rotatably assembled to the door housing 253, meshing with the sun gear 2522, and arranged radially outward of the sun gear 2522; and a cover guide 2524 disposed between the door cover housing 253 and the door cover 251, wherein the plurality of planetary gears 2523 are positioned inside the cover guide 2524, mesh with the plurality of planetary gears 2523, respectively, and when the planetary gears 2523 rotate, the cover guide 2524 rotates in a clockwise direction or a counterclockwise direction, and the door cover 251 moves forward or backward by interference with the door cover 251.
Sun gear 2522 is a pinion gear (pinion gear), and a tooth shape is formed on the outer surface of sun gear 2522 in the circumferential direction.
The planetary gear 2523 is a pinion gear, and has a tooth shape formed on the outer surface of the planetary gear 2523 in the circumferential direction. In the present embodiment, three planetary gears 2523 are arranged. The three planetary gears 2523 mesh with the outer surface of the sun gear 2522, respectively, and rotate simultaneously when the sun gear 2522 rotates.
The plurality of planetary gears 2523 and the sun gear 2522 are inserted into the moving module installation portion 2533 of the door cover housing 253. A sun gear installation portion 2534 for installing the sun gear 2522 and each planetary gear installation portion 2535 for installing each planetary gear 2523 are disposed in the moving module installation portion 2533.
A rotation shaft of the sun gear 2522 is inserted into the sun gear installation portion 2534, and the sun gear 2522 is rotatable in situ in a state of being assembled to the sun gear installation portion 2534.
The door cover motor 2521 is located further forward than the sun gear 2522. The door cover motor 2521 is located inside the moving module setting portion 2533.
A door cover motor shaft of the door cover motor 2521 is disposed from the front to the rear, and is coupled to a sun gear 2522 disposed behind the door cover motor 2521.
A motor housing 2525 is further provided to fix the door cover motor 2521 to the door cover housing 253. In the case where the door cover motor 2521 is located at the back surface of the door cover housing 253, the door cover motor 2521 may be directly fastened to the door cover housing 253.
Since the thickness of the discharge port cover 25 in the front-rear direction is increased by the above-described structure, in the present embodiment, the door cover motor 2521 is positioned inside the door cover housing 253, and the motor housing 2525 for fixing the door cover motor 2521 is disposed.
The motor housing 2525 may be assembled to the door cover housing 253. In the present embodiment, the motor housing 2525 is inserted into the moving module installation portion 2533 in a state where the door cover motor 2521 is assembled. With the above-described structure, the thickness of the discharge port cover 25 in the front-rear direction can be minimized.
The motor housing 2525 is positioned inside the cover guide 2524, and the cover guide 2524 surrounds the outside of the motor housing 2525.
The motor housing 2525 is located between the door cover motor 2521 and the cover guide 2524 when viewed from the front. The motor housing 2525 is located between the door cover housing 253 and the door cover 251 when viewed from the front-rear direction.
In order to minimize the longitudinal length when the door motor 2521 and the motor housing 2525 are assembled, the door motor 2521 is assembled to penetrate the motor housing 2525.
For this purpose, the motor housing 2525 is formed with a motor penetration portion 2525a through which the door cover motor 2521 penetrates. The motor through portion 2525a is formed along the front-rear direction. The motor through portion 2525a is located behind the core opening portion 25121a of the inner door 2512. In a state of being assembled to motor housing 2525, door motor 2521 is inserted into core opening 25121a through motor penetration portion 2525 a.
The door cover motor 2521 is inserted not only into the motor housing 2525, which is a structure to be assembled, but also into the structure of the door cover 251 that moves in the front-rear direction, and therefore, the thickness of the door assembly ii in the front-rear direction can be minimized.
The cover guide 2524 is disposed between the door cover housing 253 and the door cover 251 when viewed from the front-rear direction. The cover guide 2524 is formed in a ring shape that is open in the front-rear direction when viewed from the front.
The cover guide 2524 may receive the rotational force transmitted from the planetary gears 2523 and rotate. The cover guide 2524 is rotatable in a clockwise direction or a counterclockwise direction when viewed from the front.
The cover guide 2524 and the door cover 251 are assembled to be relatively movable, and when the cover guide 2524 is rotated, the door cover 251 can be moved forward or backward by interference with each other.
The cover guide 2524 includes: a cover guide body 25241 formed in a ring shape; a guide gear 25242 disposed along the inner peripheral surface of the cover guide body 25241 and meshing with the plurality of planetary gears 2523; the rail groove 25243 is disposed along the circumferential direction of the cover guide body 25241, is movably assembled with the moving member guide 25132, and moves forward or backward the door cover 251 by interference with the moving member guide 25132 when it rotates in the clockwise direction or the counterclockwise direction.
When the cover guide 2524 is rotated in the clockwise or counterclockwise direction by the operation of the planetary gear 2523, the moving member 2513 of the door cover 251 interferes with the cover guide 2524. When the cover guide 2524 rotates, the moving member guide 25132 does not rotate but moves along the rail groove 25243.
Guide gear 25242 is in the form of a ring gear. The guide gear 25242 is disposed on the inner peripheral surface of the cover guide body 25241.
In the present embodiment, the rail groove 25243 is formed so as to penetrate the cover guide body 25241. Unlike the present embodiment, the rail groove 25243 may be formed in a groove form. In the present embodiment, the rail groove 25243 is formed to penetrate inside and outside the cap guide 2524 in order to minimize the thickness of the cap guide 2524. In this embodiment, the moving member guide 25132 is inserted into the guide rail groove 25243.
In this embodiment, the penetrating direction of the rail groove 25243 is parallel to the front surface of the door panel 21. The coupling direction of the guide rail groove 25243 and the moving element guide 25132 is a direction intersecting the front-rear direction.
The rail groove 25243 is formed along the front-rear direction. The moving member guide 25132 interferes with the guide rail groove 25243, and the moving member guide 25132 is moved in the front-rear direction by the interference.
The rail groove 25243 is formed to extend long in the circumferential direction of the cover guide body 25241, and is formed to curve slowly forward and rearward of the cover guide body 25241. The door cover 251 can move forward or backward according to the longitudinal length of the rail groove 25243.
The rail grooves 25243 are formed at a plurality of positions, and three are arranged in this embodiment. The three rail grooves 25243 are preferably arranged at equal intervals with reference to the center of the cover guide 2524.
When the cap guide 2524 is rotated in the clockwise direction or the counterclockwise direction, the guide groove 25243 and the moving member guide 25132 interfere with each other.
Since the rail grooves 25243 are arranged in the front-rear direction along the circumferential direction of the cap guide 2524, when the cap guide 2524 rotates, the moving member guide 25132 does not rotate, but moves forward or backward along the rail grooves 25243.
The shaft center of the cover guide 2524 coincides with the shaft center of the sun gear 2522. The cover guide 2524 is inserted into the moving module installation portion 2533 and rotated inside the moving module installation portion 2533.
The guide gear 25242 is arranged in a circular shape along the inner peripheral surface of the cover guide body 25241. The guide gear 25242 is formed with a tooth shape so as to face the axial center of the cover guide 2524.
The door cover motor 2521, the plurality of planetary gears 2523, and the sun gear 2522 are disposed inside the cover guide 2524, and the thickness of the door cover movement module 252 in the front-rear direction can be minimized by the above-described structure.

The discharge port cover 25 is adjusted in height by engagement of the gear assemblies 261a, 261b and the racks 234a, 234 b. The vertical height of the spout cover 25 is maintained by the engagement of the gear assemblies 261a and 261b and the racks 234a and 234 b.
The gear assemblies 261a and 261b not only transmit the driving force of the gear driving motors 262a and 262b to the racks 234a and 234b, but also support the load of the discharge port cover 25. In the present embodiment, the gear assemblies 261a, 261b provide a structure capable of effectively supporting the load of the discharge port cover 25.
The gear assemblies 261a, 261b include: first gears 2611a, 2611b disposed on the discharge port cover 25 and meshing with the racks 234a, 234b with a first tooth-shaped portion 26111 formed on the outer peripheral surface; the 2 nd gears 2612a, 2612b, which are disposed on the discharge port cover 25, include the 2 nd-1 st tooth-shaped portion 26121 and the 2 nd-2 nd tooth-shaped portion 26122 formed by different radii of curvature, and mesh with the first tooth-shaped portion 26111 of the 1 st gears 2611a, 2611b through the 2 nd-1 st tooth-shaped portion 26121; 3 rd gears 2613a, 2613b, dispose in spit port lid 25, include 3-1 tooth-shaped portion 26131 and 3-2 tooth-shaped portion 26132 formed by different tooth profiles, mesh with 2 nd-2 nd tooth-shaped portion 26122 of 2 nd gears 2612a, 2612b through 3 rd-1 tooth-shaped portion 26131; the worm gears 2614a and 2614b are disposed on the discharge port cover 25, mesh with the 3 rd-2 nd tooth-shaped portion 26132, are connected to the gear drive motors 262a and 262b to rotate, and are disposed in the vertical direction.
Motor shafts 2621 of the gear drive motors 262a and 262b are arranged in the vertical direction.
In the present embodiment, motor shafts 2621 of the gear drive motors 262a, 262b penetrate the worm gears 2614a, 2614 b. The axial centers of the worm gears 2614a and 2614b are arranged on the same line as the motor shaft 2621.
The 1 st gears 2611a, 2611b are engaged with the racks 234a, 234b and the 2 nd gears 2612a, 2612b, respectively. The 2 nd gears 2612a and 2612b mesh with the 1 st gears 2611a and 2611b and the 3 rd gears 2613a and 2613b, respectively. The 3 rd gears 2613a and 2613b are engaged with the 2 nd gears 2612a and 2612b and the worm gears 2614a and 2614b, respectively.
The 1 st gears 2611a and 2611b, the 2 nd gears 2612a and 2612b, and the 3 rd gears 2613a and 2613b have respective tooth profiles formed as pinion types. The rotation shafts of the 1 st gears 2611a, 2611b, the 2 nd gears 2612a, 2612b, and the 3 rd gears 2613a, 2613b are formed along the front-rear direction.
In the present embodiment, in the 2 nd gears 2612a, 2612b, the diameter of the 2 nd-2 nd tooth form portion 26122 is larger than the diameter of the 2 nd-1 st tooth form portion 26121. By arranging the 2 nd-1 st tooth-shaped portion 26121 and the 2 nd-2 nd tooth-shaped portion 26122 so as to have different diameters, an engagement structure is provided which simultaneously engages with the 1 st gears 2611a, 2611b and the 3 rd gears 2613a, 2613 b.
In the present embodiment, the 3 rd-1 st tooth 26131 and the 3 rd-2 nd tooth 26132 are formed to have different diameters. The 3 rd-2 th tooth 26132 which meshes with the worm gears 2614a, 2614b may be formed larger in diameter than the 3 rd-1 st tooth 26131.
The worm gears 2614a and 2614b are cylindrical in overall shape, and their rotation axes are arranged along the vertical direction. Worm gear teeth 1771 are formed on the outer peripheral surfaces of the worm gears 2614a, 2614b, and the worm gears 2614a, 2614b are in a spiral form in the vertical direction.
Since the rotation shafts of the worm gears 2614a and 2614b are arranged along the vertical direction, the worm gear teeth 1771 can support the external force in the vertical direction.
In this embodiment, since the rotation shafts of the worm gears 2614a and 2614b are arranged along the vertical direction, the vertical direction external force applied from the 3 rd gears 2613a and 2613b can be supported. With such arrangement of the worm gears 2614a, 2614b, it is possible to prevent the discharge port cover 25 from moving downward due to its own weight without providing an additional stopper or the like.
In this embodiment, the self weight of the discharge port cover 25 can be supported by the engagement of the racks 234a and 234b and the 1 st gears 2611a and 2611b and the engagement of the worm gears 2614a and 2614b and the 3 rd gears 2613a and 2613 b.
The worm gears 2614a, 2614b are directly connected to motor shafts 2621 of the gear drive motors 262a, 262 b. Motor shafts 2621 of the gear drive motors 262a and 262b vertically penetrate the rotation centers of the worm gears 2614a and 2614 b.
In the present embodiment, the gear drive motors 262a and 262b are stepping motors, and the worm gears 2614a and 2614b can be prevented from rotating by external force applied to the 3 rd gears 2613a and 2613 b.
The 1 st gears 2611a, 2611b project outward of the side surface 2531b of the door housing body 2531. A part of the 1 st gears 2611a and 2611b protrudes outward from the door housing main body 2531 through a side surface hole 2531c formed in the side surface 2531b of the door housing main body 2531.
The first tooth portions 26111 of the 1 st gears 2611a, 2611b that project outward of the side surface 2531b of the door cover housing main body 2531 mesh with the rack tooth portions 2341 of the racks 234a, 234 b. Since the first tooth portion 26111 and the rack tooth portion 2341 are formed along the front-rear direction, they are kept in a state of meshing with each other in the up-down direction.
A guide rib 2536 is disposed in front of the first tooth portion 26111 and the rack tooth portion 2341. The guide rib 2536 is located on a plane on which the 2 nd gears 2612a and 2612b are arranged in the front-rear direction.
Since the spout cover moving modules 26a and 26b move in the up-down direction, the cables connected to the spout cover moving modules 26a and 26b inevitably move in the up-down direction.
Since the front-rear direction thickness of the door assembly ii is very small compared to its width, when the discharge port cover moving modules 26a, 26b move up and down, a cable entanglement will likely occur.
Further, the cables may be pinched between the discharge port cover moving modules 26a, 26b that move up and down and the upper panel 23, thereby restricting the operation of the discharge port cover moving modules 26a, 26 b. To minimize the problems described above, a cable guide 27 may be provided.
The upper end of the cable guide 27 is assembled to the discharge port cover 25, and the lower end is assembled to the upper panel 23.
The cable guide 27 includes: a first cable guide 271 which is relatively rotatably assembled to the discharge port cover 25; a second cable guide 272 assembled to the upper panel 23 in a relatively rotatable manner; the connection cable guide 273 is assembled with the first cable guide 271 and the second cable guide 272 in a relatively rotatable manner.
The first cable guide 271 includes a first cable guide body 2711 in which a space for arranging a cable is formed inside. The first cable guide body 2711 is formed with bent portions 2711a and 2711b bent in different directions at both ends connected to the spout cover 25 or the connection cable guide 273.
The second cable guide 272 also includes a second cable guide main body 2721 in which a space for arranging the cable is formed and bent portions 2721a and 2721b are arranged at both ends, and the connection cable guide 273 also includes a connection cable guide main body 2731 in which a space for arranging the cable is formed and bent portions 2731a and 2731b are formed at both ends.
The cable guide 27 of the present embodiment may include: a first pin 2741 for assembling the first cable guide 271 and the door cover case 253 in a relatively rotatable manner; the second pin 2742 makes the first cable guide 271 and the connection cable guide 273 assembled in a relatively rotatable manner; a third pin 2743 to assemble the connection cable guide 273 and the second cable guide 272 in a relatively rotatable manner; and a fourth pin 2744 for assembling the second cable guide 272 and the upper panel 23 in a relatively rotatable manner.
The first cable guide 271 and the connection cable guide 273 form an included angle of 180 degrees or less, and when the discharge port cover 25 is lowered, the included angle between the first cable guide 271 and the connection cable guide 273 becomes smaller.
The second cable guide 272 and the connection cable guide 273 form an included angle of 180 degrees or less, and when the discharge port cover 25 is lowered, the included angle between the second cable guide 272 and the connection cable guide 273 is reduced.

In addition, images captured and acquired by the camera may be stored in the memory 815.
According to an embodiment, the position of the user may be detected based on the image acquired from the camera module 22.
The camera module 22 is provided to the door panel 21, and may be provided to an upper side panel of the cabinet according to circumstances. The camera module 22 is accommodated in the cabinet assembly i when not operated, and is also operated after being lifted.
The control part 800 may be composed of one or more microprocessors (Micro processors).
Referring to fig. 20, the control part 800 may include, according to functions: a main control unit 801, a camera module control unit 802, a power supply control unit 803, an illumination control unit 804, a display module control unit 805, a humidification module control unit 806, a filter cleaning module control unit 807, and the like.
Each of the control units (801 to 807) may be constituted by one microprocessor, and may be provided in each module. For example, the camera module 22, the filter cleaning assembly vii, and the humidifying assembly v may be controlled by a single microprocessor.
According to the embodiment, the main control portion 801 may apply a control instruction to the remaining control portions (802 to 807), receive data from the respective control portions, and perform processing.

For example, the display module 29 may be provided with a display module control unit 805, and the humidifying unit v may be provided with a humidifying unit control unit 806 to control the operation thereof.
The block diagram of the control unit 800 shown in fig. 20 is a block diagram used in an embodiment of the present invention. Each component of the block diagram may be integrated, added, or omitted depending on the arrangement of the control unit 800 and the unit in the air conditioner that are actually implemented. That is, two or more components may be integrated into one component or one component may be subdivided into two or more components as necessary. Further, the functions performed in the respective blocks are for explaining the embodiments of the present invention, and the specific actions or means thereof are not intended to limit the scope of the claims of the present invention.
Referring to fig. 21, the air conditioner may include: a camera module 22; a sensor section 810 for detecting various data; an audio input part 820 for receiving a voice instruction of a user; an operation section 830; a memory 815 for storing various data; a communication unit 850 for performing wireless communication with another electronic apparatus; a drive unit 860 for executing an operation implemented in the air conditioner; a display module 29 for displaying prescribed information in an image manner; an audio output unit 840 for outputting predetermined information in an audio manner; a humidifying component V; the filter cleaning component VII is arranged; a control unit 800 for controlling the overall operation; and a processor 880.
The internal block diagram of the air conditioner of fig. 21 is similar to that of fig. 19, and is different in that a processor 880 is further provided, and an audio input portion 820, an audio output portion 840, a communication portion 850, and the processor 880 are provided in a voice recognition module 819, which is a single module.
According to an embodiment, the voice recognition module 819 may include a communication section 850 and a processor 880, and the audio input section 820 and the audio output section 840 may be constructed as an additional integrated module.
In addition, the processor 880 may control the audio input part 820, the audio output part 840, the communication part 850, and the like.
Hereinafter, description will be made centering on differences from fig. 19.
The processor 880 may process a voice input signal of the user received through the audio input part 820 and perform a voice recognition process.
For example, in case of receiving a wake up voice signal containing a preset call, the processor 880 may transition to a state for receiving a voice instruction. In this case, the processor 880 performs only a voice recognition process until or not calling voice input, and subsequent voice recognition related to user voice input may be performed by the voice recognition server system.
The processor 880 may control to transmit a user's voice command input after recognition of a wake up (wake up) voice signal to the voice recognition server system through the communication part 850.
The processor 880 may transmit the state information of the air conditioner, the voice command of the user, and the like to the voice recognition server system and the like through the communication unit 850.
When the control signal is received through the communication unit 850, the processor 880 transmits the control signal to the control unit 800, and the control unit 800 may control the air conditioner to operate according to the received control signal.
As a result, voice data acquisition, communication with the server system, and corresponding audio output can be performed by the voice recognition module 819.
In addition, the voice recognition module 819 may be attached to various electronic devices in addition to the air conditioner. Or may be used as an additional device rather than attached to other electronic devices.
The air conditioner of an embodiment of the invention can receive the voice input of a user, and the voice recognition server system can control the air conditioner by recognizing and analyzing the voice input of the user.
Thus, the user can control the air conditioner without operating the portable terminal or the remote control device.
Referring to fig. 6 to 7 and 22, an air conditioner according to an embodiment of the present invention may include: a door panel 21 for forming the appearance of a front face; a discharge port cover 25 disposed on the door panel 21 and moving in the vertical direction to open and close; gear drive motors 262a, 262b for powering discharge port cover moving modules 26a, 26b for driving the discharge port cover 25; a position sensor unit 235, which is disposed on the inner surface of the door panel 21 and includes an upper end position sensor 235a and a lower end position sensor 235b for detecting the movement of the discharge port cover 25; and a control unit 800 for controlling the rotation of the gear drive motors 262a and 262b based on the detection data of the upper end position sensor 235a and the lower end position sensor 235 b.
The inner surface of the door panel 21 may include a gear member, a rail member, a stopper (stopper) member, and the like for moving the discharge port cover 25 in the upward or downward direction in response to the rotation of the gear drive motors 262a and 262b and the gear drive motors 262a and 262 b.
The control section 800 may open or close the discharge port cover 25 by rotating the gear driving motors 262a, 262 b.
The control unit 800 may control the discharge port cover 25 to move in the downward direction and be opened based on a product on (on) command, and may control the discharge port cover 25 to move in the upward direction and be closed based on a product off (off) command.
In this specification, the product-off (off) instruction may be a power-off input for turning off the power of the air conditioner. Alternatively, the product off command may be a command corresponding to a specific mode in which the front air blower module 31 is not operated and the discharge port cover 25 is closed.
In this specification, the product on command may be a power on input that turns on the power of the air conditioner. Alternatively, the product on command may be a command corresponding to a specific mode in which the spout cover 25 is opened and the front air blowing module 31 is operated.
In addition, when the discharge port cap 25 is opened or closed by sliding movement in the up-down direction, noise may occur in the case of over-swinging to a stopper (stopper).
Such noise will likely give an uncomfortable feeling to the user and reduce the reliability of the product. Therefore, the present invention proposes a configuration in which the position of the spout cover 25 can be easily confirmed and accurately controlled when the spout cover is slid in the vertical direction.
To this end, an air conditioner according to an embodiment of the present invention may include: the position sensor unit 235 is disposed on the inner surface of the door panel 21, and includes an upper end position sensor 235a and a lower end position sensor 235b for detecting the movement of the discharge port cover 25.
The present invention is not limited to the detection method of the position sensor unit 235, and various sensors can be used.
For example, the upper end position sensor 235a and the lower end position sensor 235b may be formed of an infrared IR transceiving module. The control unit 800 may control the gear drive motors 262a and 262b based on the detected position information by detecting the position of the discharge port cover 25 by positioning the infrared IR transceiver module at the movement start point (highest point) and the movement end point (lowest point) of the discharge port cover 25.
Alternatively, the position sensor unit 235 may detect whether or not the discharge port cover 25 is opened or closed and/or the position thereof using a Hall (Hall) IC, a trigger switch, a rotary switch, or the like.
The sensor part 810 may include the position sensor part 235, and the control part 800 may control the air conditioner based on detection data of the position sensor part 235.
According to an embodiment, the control part 800 may include: a first control unit 245 for controlling the movement of the position sensor unit 235 and the spout cover 25; and a second control unit (not shown) for controlling the front air blowing module 31.
According to an embodiment, the first control part 245 may be a display module control part 805 for controlling the display module 29.
The plate closest to the upper end position sensor 235a and the lower end position sensor 235b and the gear drive motors 262a and 262b disposed on the inner side surface of the door panel 21 may be a plate (board) provided in the display module 29.
Therefore, the display module control unit 805 provided in the display module 29 receives and processes the data detected by the upper end position sensor 235a and the lower end position sensor 235b, and controls the rotation of the gear drive motors 262a and 262b, whereby the connection structure can be further simplified and the processing speed can be increased.
In addition, the second control portion may be the main control portion 801. The main control unit 801 can control the driving, movement, and rotation of the fan of the front air blowing module 31. According to the embodiment, the driving unit 860 may control at least one of the driving, movement, and rotation of the fan of the front air blowing module 31 according to the control of the main control unit 801.
The front air supply module 31 may include: a circulation fan 810; a circulator rotating part 820 that can rotate at least the circulation fan 810 so as to change the direction in which the circulation fan 810 is rotated; the circulator moving unit 830 can move at least the circulation fan 810.
The circulator rotation part 820 may include a two-axis rotation structure using a double joint (joint), rack and pinion structure. This enables the entire front air blowing module 31 or at least the direction in which the circulation fan 810 faces to be freely rotated in various directions.
Circulator moving unit 830 may include a motor and a mechanism structure for advancing or retreating front blower module 31. For example, circulator moving unit 830 may include a step motor, a gear member that moves front air supply module 31 as the step motor rotates, a rail member, and the like.
The front air blowing module 31 can operate under the control of the main control unit 801. The main control unit 801 may control the front air blowing module 31 in an intelligent (smart) manner according to the user position detected by the upper proximity sensor and/or the camera module 22.
For example, when a user is detected at a long distance, the front air supply module 31 is controlled to rotate upward, and then the circulation fan 810 is driven, so that air can be further sent to approach the user during cooling and air purification.
The front blowing module 31 may perform a backward movement based on a product off command and a forward movement based on a product on (on) command.
The control unit 800 may control the discharge port cover 25 to move in the downward direction and be opened based on a product on (on) command, and may control the discharge port cover 25 to move in the upward direction and be closed based on a product off (off) command.
The display module control section 805 may control the discharge port cover 25 to move in the downward direction to be opened based on a product on (on) instruction, and control the discharge port cover 25 to move in the upward direction to be closed based on a product off (off) instruction.
In the air conditioner according to the embodiment of the present invention, the front air blowing module 31 can move forward and operate after the discharge port cover 25 is opened.
When a product off (off) command is received from a user by voice input or touch input through the display module 29, the front blower module 31 may be retracted and accommodated inside the cabinet assembly i.
Before the discharge port cover 25 and the front blower module 31 move, the control unit 800 can determine the current position of the discharge port cover 25 by checking the detection data of the position sensor unit 235.
For example, the control unit 800 may determine that the discharge port cover 25 is closed when the discharge port cover 25 is detected only by the upper end position sensor 235a disposed at the movement start point (highest point) of the discharge port cover 25.
The control unit 800 may determine how far the discharge port cover 25 is from the movement start point (highest point) of the discharge port cover 25 based on the detection value of the upper end position sensor 235 a.
Further, the control unit 800 may determine that the discharge port cover 25 is opened when the discharge port cover 25 is detected only by the lower end position sensor 235b disposed at the end point (lowest point) of the movement of the discharge port cover 25.
The control unit 800 may determine how far the discharge port cover 25 is from the end point (lowest point) of the movement of the discharge port cover 25 based on the detection value of the lower end position sensor 235 b.
The control unit 800 can perform the vertical sliding movement of the discharge port cover 25 in accordance with the current position of the discharge port cover 25 and the operation command.
For example, the display module control unit 805 may control the spout cover 25 to move downward and be opened in response to a product opening touch instruction by the display module 29.
The display module control unit 805 may control the discharge port cover 25 to move upward and be closed according to a product closing touch command by the display module 29.
The display module control unit 805 can control the movement of the discharge port cover 25 under the control of the main control unit 801.
Further, the control unit 800 may control the rotation speed of the gear drive motors 262a and 262b to be reduced when the discharge port cover 25 is detected at a predetermined position corresponding to the opening/closing operation, and may control the gear drive motors 262a and 262b to finally stop the rotation when the discharge port cover 25 reaches a preset starting point (highest point) or ending point (lowest point).
When the discharge port cover 25 is detected by the upper end position sensor 235a upon receipt of a product open (on) command, the control unit 800 may control the discharge port cover 25 to move in the downward direction.
That is, the control unit 800 determines the initial position of the discharge port cover 25 before starting the opening (open) operation of the discharge port cover 25 in response to the product open (on) command, and can start the opening (open) operation when there is no abnormality.
While moving from the initial position to the predetermined position, the control unit 800 may control the gear drive motors 262a and 262b to rotate at a preset maximum setting value. The control unit 800 may be driven to maximize (Max) the amount of movement of the discharge port cover 25 by the gear drive motors 262a and 262 b. And may be driven to maximize (Max) the moving speed and/or the moving amount based on the gear driving motors 262a, 262 b.
After the opening (open) operation of the discharge port cover 25 is started in response to the product open (on) command, the control unit 800 may control the rotation speed of the gear drive motors 262a and 262b to be reduced when the discharge port cover 25 is detected by the lower end position sensor 235 b.
When the lower end position sensor 235b detects that the discharge port cover 25 reaches the preset lowest point, the control unit 800 may control the gear drive motors 262a and 262b to stop.
When the discharge port cover 25 is suddenly stopped, noise may occur in the gear drive motors 262a and 262 b.
Further, the spout cover 25 continues to advance the stopper in an over-swing manner, and noise may occur.
Therefore, by decelerating the discharge port cover 25 before it is completely opened, the possibility of occurrence of overshoot and noise can be further reduced.
When the discharge port cover 25 is detected by the lower end position sensor 235b upon receiving a closing (off) command, the control unit 800 may control the discharge port cover 25 to move in the upward direction.
That is, the control unit 800 may determine the initial position of the discharge port cover 25 before starting the closing (close) operation of the discharge port cover 25 in response to the product off command, and may start the closing (close) operation when there is no abnormality.
In this case, the control unit 800 may control the gear drive motors 262a and 262b to rotate at a preset maximum setting value while moving from the initial position to the predetermined position. The control unit 800 may be driven to maximize (Max) the amount of movement of the discharge port cover 25 by the gear drive motors 262a and 262 b. Also, it may be driven to maximize (Max) the moving speed and/or the moving amount based on the gear driving motors 262a, 262 b.
After the closing (close) operation of the discharge port cover 25 is started in response to the product close (off) command, the control unit 800 may control the rotation speed of the gear drive motors 262a and 262b to be reduced when the discharge port cover 25 is detected by the upper end position sensor 235 a.
When the upper end position sensor 235a detects that the ejection port cover 25 reaches the preset maximum point, the control unit 800 may control the gear drive motors 262a and 262b to stop.
By decelerating the speed of the discharge port cover 25 before it is completely closed, the possibility of occurrence of overshoot and noise can be further reduced.
Further, it is possible to provide time and opportunity for the user to remove his or her hand before the spout cover 25 is completely closed, and it is possible to further reduce the possibility of a safety accident such as a hand pinching accident.
When the lower end position sensor 235b starts detecting the discharge port cover 25 during the opening operation of the discharge port cover 25, the display module control unit 805 may decelerate the RPM of the gear drive motors 262a and 262 b. The display module control unit 805 may control the discharge port cover 25 to stop at the end point (lowest point).
When the upper end position sensor 235a starts detecting the discharge port cover 25 during the closing operation of the discharge port cover 25, the indicator block control section 805 may decelerate the RPM of the gear drive motors 262a and 262 b. The display module control unit 805 may control the ejection port cover 25 to stop at a start point (highest point).
This makes it possible to realize accurate position control and an anti-overshoot design of the spout cover 25, and to prevent or reduce noise that may occur during opening or closing of the spout cover 25.
Further, the possibility of a safety accident can be reduced by decelerating the spout cover 25 at a specific position during the opening or closing thereof. For example, in the process of closing the discharge port cover 25, the RPM of the gear drive motors 262a and 262b is decelerated at a predetermined position spaced apart from the starting point (highest point) position, which is the final closed position, so that the possibility of occurrence of a pinching safety accident can be reduced.
In addition, in the process of checking the initial position of the spout cover 25 corresponding to the product opening/closing operation command, there is a possibility that an abnormal state in which the spout cover 25 cannot be detected occurs. Such an abnormal situation may occur due to a power failure, initialization, mechanism locking, or the like.
In the initial position confirmation process, if the upper end position sensor 235a and the lower end position sensor 235b fail to detect the discharge port cover 25, the control unit 800 may control the discharge port cover 25 to move in the upward direction.
That is, if both the upper end position sensor 235a and the lower end position sensor 235b disposed in a spaced-apart manner fail to detect the discharge port cover 25, the control unit 800 may control the discharge port cover 25 to move in the upward direction and check whether the detection is possible by the upper end position sensor 235 a.
In this case, the control unit 800 may control the gear drive motors 262a and 262b to rotate at a preset maximum setting value.
Further, when the upper end position sensor 235a detects the discharge port cover 25 as the discharge port cover 25 moves in the upper direction, the control unit 800 controls the rotation speed of the gear drive motors 262a and 262b to be reduced, thereby reducing the excessive vibration and noise that may occur during the abnormal condition coping process.
In this case, the control unit 800 may control the gear drive motors 262a and 262b to stop when the upper end position sensor 235a detects that the discharge port cover 25 reaches the preset maximum height.
Even if the discharge port cover 25 is moved in the upward direction, the control unit 800 may control the gear drive motors 262a and 262b to stop if the upper end position sensor 235a fails to detect the discharge port cover 25.
That is, even if the discharge port cover 25 is moved in the upward direction to maximize the detection of the discharge port cover 25, the discharge port cover 25 may not be moved any more if the detection of the discharge port cover 25 fails.
The condition may be determined to be a sensor failure. In this case, the audio output portion 840 may acoustically output information for prompting a failure of the position sensor portion 235. Also, the display module 29 may display information for prompting a failure of the position sensor portion 235.
Therefore, the device can flexibly respond to the variables such as power failure, initialization, mechanism locking and the like, and improve the noise of mechanism overstroke.
Further, if the position sensors 235a and 235b, which cannot acquire position signals after the maximum (Max) step of the gear drive motors 262a and 262b, fail, the gear drive motors 262a and 262b are stopped, and additional noise occurrence and failure modes can be coped with.
Also, sensor failures may be prompted to a user.
In addition, during the closing of the spout cover 25, there is a possibility that a safety accident may occur in which the user's hand is caught between the spout and the closing spout cover 25.
In order to prevent such a situation, the air conditioner according to an embodiment of the present invention may further include: a proximity sensor (not shown) is disposed on the door panel 21 and detects whether the user approaches the door panel. Alternatively, the position information of the user may be acquired by the camera module 22 including more than one camera.
In this case, the control unit 800 may control the opening and closing operation of the discharge port cover 25 based on data detected by the proximity sensor and/or the camera module 22.
The control unit 800 may control the operation of the front air blowing module 31 based on data detected by the proximity sensor and/or the camera module 22.
According to the present invention, by controlling the driving, movement, and rotation of front air-blowing module 31 based on the user position, it is possible to realize air flow control optimized for the user position.
< control method >
Referring to fig. 23, the air conditioner may receive a product on (on) operation command (step S110).
The user may input a product on (on) action command using a voice input or a touch input through the display module 29 or a remote controller operation, etc.
The upper end position sensor 235a may detect an initial position of the spout cover 25 according to a product opening (on) operation command (step S120).
That is, the control unit 800 checks the detection data of the upper end position sensor 235a in response to the product on operation command (step S120), and may control the opening operation to be started (open) when there is no abnormality (step S130).
In this case, while moving from the initial position to the predetermined position, the control unit 800 may control the gear drive motors 262a and 262b to be driven in the maximum (Max) step (step S930). For example, the control unit 800 may be driven to maximize (Max) the amount of movement of the discharge port cover 25 by the gear drive motors 262a and 262 b.
Subsequently, when the discharge port cover 25 is detected by the lower end position sensor 235b (step S140), the control unit 800 may control the RPM of the gear drive motors 262a and 262b to be reduced (step S150).
When the lower end position sensor 235b detects that the discharge port cover 25 has reached the preset lowest point, the control unit 800 may control the gear drive motors 262a and 262b to stop (step S160).
This prevents the discharge port cover 25 from being opened by excessive vibration and noise.
Referring to fig. 24, the air conditioner may receive a product off (off) operation command (step S210).
The user may input a product-off action command using a voice input or a touch input through the display module 29 or a remote controller operation, etc.
The lower end position sensor 235b can detect the initial position of the spout cover 25 in response to the product off operation command (step S220).
That is, the control unit 800 checks the detection data of the lower end position sensor 235b in response to the product off operation command (step S220), and may control the closing operation to be started when there is no abnormality (step S230).
In this case, the control part 800 may control the gear driving motors 262a and 262b to be driven in the maximum (Max) step during the movement from the initial position to the prescribed position (step S1430). For example, the control unit 800 may be driven to maximize (Max) the amount of movement of the discharge port cover 25 by the gear drive motors 262a and 262 b.
Subsequently, when the discharge port cover 25 is detected by the upper end position sensor 235a (step S240), the control unit 800 may control the RPM of the gear drive motors 262a and 262b to be reduced (step S250).
When the upper end position sensor 235a detects that the ejection port cover 25 reaches the preset maximum point, the control unit 800 may control the gear drive motors 262a and 262b to stop (step S260).
This prevents the discharge port cover 25 from being excessively swung or noisy during closing.
Referring to fig. 25, when the spout cover 25 is located in the intermediate position area between the upper end position sensor 235a and the lower end position sensor 235b, if an abnormal condition such as power-off (off), power failure, or initial reset occurs, an abnormal operation condition may occur (step S310).
Under such abnormal operation conditions, both the upper end position sensor 235a and the lower end position sensor 235b cannot detect the discharge port cover 25 (step S320).
In this case, the control unit 800 may perform the initialization compensation operation by the closing operation, and may detect the discharge port cover 25 by the upper end position sensor 235 a. In this case, the control unit 800 may control the gear drive motors 262a and 262b to operate in the maximum (Max) step (step S330).
When the upper end position sensor 235a starts detecting the discharge port cover 25 (step S340), the control unit 800 may control the RPM of the gear drive motors 262a and 262b to be reduced (step S350).
When the upper end position sensor 235a detects that the ejection port cover 25 reaches the preset maximum point, the control unit 800 may control the gear drive motors 262a and 262b to stop (step S360).
When the discharge port cover 25 is not detected by the upper end position sensor 235a, the control unit 800 may unconditionally stop the discharge port cover 25 and respond to the sensor failure mode. In the sensor failure mode, the control part 800 may control the audio output part 840 and/or the display module 29 to be able to output a message for prompting a sensor failure.
This enables effective handling even in the event of an abnormal situation.

Also, according to at least one of the embodiments of the present invention, it is possible to effectively control the circulator door motor using detection data sequentially detected in the upper end position sensor and the lower end position sensor at the time of product opening/closing.
Further, according to at least one of the embodiments of the present invention, it is possible to effectively cope with an abnormal situation in which the circulator door cannot be detected in the upper end position sensor and the lower end position sensor.
Also, according to at least one of the embodiments of the present invention, it is possible to variously and effectively control the air flow.
