The invention discloses a cabinet air conditioner and an air conditioner control method, which can provide power for the cabinet air conditioner in various functional states through one motor, and are beneficial to air conditioner products to meet market demands of functional diversification, equipment miniaturization and integration.
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 and 2, the cabinet air conditioner provided by the embodiment of the invention includes a housing, a first fan 1, a second fan 4, a first motor, and a lifting mechanism. Wherein:
the shell comprises an upper functional area and a lower functional area, the first fan 1 is arranged in the upper functional area, and the second fan 4 is arranged in the lower functional area;
the first motor is in transmission connection with the first fan 1 and is used for controlling the first fan 1 to rotate around the shaft;
the lifting mechanism is in transmission connection with the second fan 4 and is used for controlling the second fan 4 to axially lift;
if the second fan 4 is lifted to the first height position, the second fan 4 is in transmission connection with the first fan 1;
if the second fan 4 is lowered to the second height position, the transmission connection relationship between the second fan 4 and the first fan 1 is released.
As can be seen, in the cabinet air conditioner provided by the embodiment of the invention, the first fan 1 and the second fan 4 are provided, and when the transmission connection relationship between the first fan 1 and the second fan 4 is released, the first motor only drives the first fan 1 to rotate so as to meet the working requirement of the upper functional area; when the first fan 1 and the second fan 4 are in transmission connection, the first motor can drive the first fan and the second fan to synchronously rotate, so that the working requirements of the upper functional area and the lower functional area are met at the same time. Therefore, in the cabinet air conditioner provided by the embodiment of the invention, the cabinet air conditioner can be powered under various functional states through one main motor (the first motor), so that the functional diversity of air conditioner products is realized, and the market demands of equipment integration and miniaturization are met.
It should be noted that the "transmission connection" may be implemented by a gear transmission connection structure, or may be implemented by a circumferential limit structure. The method is characterized in that when in specific implementation:
if a gear transmission connection structure is adopted to realize transmission connection between the first fan 1 and the second fan 4, the following steps are adopted: "drivingly connected" means that a plurality of gears are engaged with each other so that the first fan 1 drives the second fan 4 to rotate synchronously; the "transmission connection release" means that the adjacent gears are disengaged from each other to allow the first fan 1 to rotate alone. Wherein, the engagement/disengagement between adjacent gears can be realized by driving a certain gear to axially displace/radially displace by a driving mechanism.
If a circumferential limit structure is used to achieve the driving connection between the first fan 1 and the second fan 4, as will be described below: the transmission connection is that the shaft end and the shaft sleeve are mutually spliced and then are circumferentially clamped and limited, so that the first fan 1 drives the second fan 4 to synchronously rotate; "drive connection release" means that the shaft end and the shaft sleeve are disengaged from each other to allow the first fan 1 to rotate alone.
In a specific embodiment, the lower end shaft of the first fan 1 and the upper end shaft of the second fan 4 are in transmission connection through a circumferential limit structure, and the circumferential limit structure comprises a limit shaft end and a limit shaft sleeve. If the lower end shaft of the first fan 1 is the limiting shaft end, the upper end shaft of the second fan 4 is the limiting shaft sleeve; if the upper end shaft of the second fan 4 is the limiting shaft end, the lower end shaft of the first fan 1 is the limiting shaft sleeve. Specifically, please refer to fig. 6 to 8:
the outer wall of the limiting shaft end is provided with a plurality of circumferential limiting protrusions 101 at intervals along the circumferential direction, and the end part of each circumferential limiting protrusion 101, which is close to the limiting shaft sleeve, is of a spherical structure;
a plurality of circumferential limiting clamping grooves 201 are formed in the side wall of the central hole of the limiting shaft sleeve at intervals along the circumferential direction, and the circumferential limiting clamping grooves 201 correspond to the circumferential limiting protrusions 101 one by one and are structurally adaptive;
the end part of the side wall of the central hole of the limiting shaft sleeve, which is close to the limiting shaft end, is provided with a variable profile guide surface 202, and the variable profile guide surface 202 is used for guiding the circumferential limiting protrusion 101 into the circumferential limiting clamping groove 201.
Referring to fig. 7 and 8, when the limiting shaft end moves toward the limiting shaft sleeve, if the circumferential limiting protrusion 101 of the limiting shaft end is not aligned with the circumferential limiting clamping groove 201 of the limiting shaft sleeve, but falls onto the profile-variable guiding surface 202 between adjacent circumferential limiting clamping grooves 201, relative rotation occurs between the shaft end and the shaft sleeve under the guiding action of the profile-variable guiding surface 202 (assuming that the limiting shaft sleeve is not moved, the moving direction of the limiting shaft end moves downward and rotates at the same time as the arrow in fig. 8), so that the circumferential limiting protrusion 101 gradually slides into the circumferential limiting clamping groove 201 along the direction of the left arrow or the right arrow in fig. 7. Thereby, a driving connection between the first fan 1 and the second fan 4 is achieved.
Referring to fig. 1, 2, 4 and 5, in the embodiment, the cabinet air conditioner further includes a first middle spacer 3 and an upper sliding cover 12. Wherein: the first middle spacer 3 is fixedly arranged in the shell and is provided with a first through hole, and the upper sliding cover 12 is sleeved in the first through hole in an axially sliding manner; the upper end shaft of the second fan 4 is rotatably connected with the upper slide cover 12.
Specifically, the upper sliding cover 12 is provided with an upper cover passing hole, and a first bearing 10 (specifically, a ball bearing may be used) is provided between the upper end shaft of the second fan 4 and the upper cover passing hole, so that the rotational connection between the second fan 4 and the upper sliding cover 12 is achieved through the first bearing 10.
Therefore, in the cabinet air conditioner, the first middle spacer 3 and the first bearing 10 can play a role in radial limiting on the upper end shaft of the second fan 4, so that the excessive shaking of the fan is prevented; the second fan 4 can be made axially slidable by the upper slide cover 12. As shown in fig. 4, when the second fan 4 is in driving connection with the first fan 1 after being lifted, the upper slide cover 12 slides upward relative to the first middle spacer 3; as shown in fig. 5, when the second fan 4 is disconnected from the first fan 1 after being lowered, the upper slide cover 12 slides downward with respect to the first intermediate spacer 3.
In particular embodiments, the lifting mechanism is preferably a cam lifting mechanism. Referring to fig. 2 and 3, the cam lifting mechanism comprises a second motor 7 and a cam 8. If the second motor 7 drives the cam 8 to rotate to the first working position, the second fan 4 is lifted to the first height position by the cam 8 and is in transmission connection with the first fan 1; if the second motor 7 drives the cam 8 to rotate to the second working position, the second fan 4 is lowered to the second height position, and the transmission connection relationship between the second fan 4 and the first fan 1 is released.
Further, the cam lifting mechanism also comprises a bottom support plate 6 and a lower sliding cover 9. The bottom support plate 6 is fixedly arranged in the shell, and is provided with a second through hole, and the lower sliding cover 9 is sleeved in the second through hole in an axially sliding manner; the lower end shaft of the second fan 4 is rotationally connected with the lower sliding cover 9; the cam 8 is used for driving the lower sliding cover 9 to axially lift and lower so as to control the second fan 4 to lift and lower.
Specifically, the lower slide cover 9 is provided with a lower cover passing hole, and a second bearing 11 (specifically, a ball bearing may be used) is provided between the lower end shaft of the second fan 4 and the lower cover passing hole, so that the rotational connection between the second fan 4 and the lower slide cover 9 is achieved through the second bearing 11.
In the cam lifting mechanism, the bottom supporting disc 6 and the second bearing 11 can play a role in radial limiting on the lower end shaft of the second fan 4, so that the fan is prevented from excessively shaking; the second fan 4 can be made axially slidable by the lower slide cover 9. As shown in fig. 4, when the second fan 4 is in driving connection with the first fan 1 after being lifted, the lower sliding cover 9 slides upwards relative to the bottom supporting plate 6; as shown in fig. 5, when the second fan 4 is disconnected from the first fan 1 after being lowered, the lower slide cover 9 slides downward with respect to the bottom support plate 6.
Referring to fig. 1 and 2, in a specific embodiment, a second middle spacer 2 is further disposed above the first middle spacer 3, the second middle spacer 2 is fixedly disposed in the housing, and a third through hole is disposed, and a lower end shaft of the first fan 1 is rotatably sleeved in the third through hole.
Specifically, as shown in fig. 2, 4 and 5, the shoulder of the lower end shaft of the first fan 1 is located above the third through hole to play an axial supporting role for the first fan 1; furthermore, a third bearing 13 (specifically, a rubber bearing may be used) is disposed between the lower end shaft of the first fan 1 and the third through hole, so that the rotational connection between the lower end shaft of the first fan 1 and the third through hole of the second middle spacer 2 is achieved through the third bearing 13.
Specifically, the first middle spacer 3 is a water receiving disc, and the second middle spacer 2 is an air duct chassis. But is not limited thereto, and in other embodiments, a person skilled in the art may also adopt other structures as the first intermediate spacer 3 and the second intermediate spacer 2 described above.
Specifically, the upper functional area in the cabinet air conditioner is provided with a refrigeration system, the refrigeration system is a conventional refrigeration system, and main functional parts generally comprise a compressor, an evaporator, a condenser and the like; the air outlet direction of the first fan 1 corresponds to the first air outlet area of the shell. When the refrigeration system works, the first air outlet area outputs temperature-regulating air flow.
Specifically, an auxiliary system is arranged in the lower functional area of the cabinet air conditioner, and the auxiliary system is any one of an air purifying system, a sterilizing system and a humidifying system, or a combination of two or all of the two; the air outlet direction of the second fan 4 corresponds to the position of the second air outlet area of the shell. When the system is assisted, the second outlet area outputs optimized (i.e., purified/sterilized/humidified) air.
Specifically, a first air outlet area corresponding to the position of the first fan 1 and a second air outlet area corresponding to the position of the second fan 4 are arranged on a panel of the cabinet air conditioner. And the shell is internally provided with a first driving mechanism and a second driving mechanism, the first driving mechanism is used for controlling the independent opening and closing of the air deflector of the first air outlet area, and the second driving mechanism is used for controlling the independent opening and closing of the air deflector of the second air outlet area. When a functional system (such as a refrigerating system) in the upper functional area works, the first driving mechanism controls the air deflector of the first air outlet area to be opened; the second drive mechanism controls the opening of the air deflector of the second air outlet zone when the functional system (e.g., air purification system/sterilization system/humidification system) in the lower functional zone is operated.
Further, a protective net structure is arranged outside the second air outlet area so as to avoid accidental injury to children, pets and the like.
Further, in the cabinet air conditioner, the first middle spacer 3, the second middle spacer 2, and the bottom support plate 6 are fixedly connected with the upright post 5 inside the casing. Wherein, the junction between first well spacer 3 and stand 5, the junction between second well spacer 2 and stand 5, the junction between bottom sprag dish 6 and stand 5 adopts screw 15 to fasten respectively to connect, and still overlaps on the screw 15 and is equipped with vibration isolator 14. The concrete installation structure of the vibration isolator 14 and the screw 15 is shown in fig. 9.
In addition, the embodiment of the invention also provides an air conditioner control method which is suitable for the cabinet air conditioner. The air conditioner control method at least comprises the following steps:
when the cabinet air conditioner is in a temperature-adjusting working condition, the transmission connection relation between the second fan 4 and the first fan 1 is released, the temperature-adjusting system is in a working state, and the first motor drives the first fan 1 to rotate so as to enable a first air outlet area of the cabinet air conditioner to output temperature-adjusting air flow;
when the cabinet air conditioner is in an optimized working condition, the second fan 4 is controlled to ascend axially through the lifting mechanism, so that the second fan 4 is in transmission connection with the first fan 1, the temperature regulating system and the auxiliary system are in working states, the first motor drives the first fan 1 and the second fan 4 to synchronously rotate, so that the first air outlet area of the cabinet air conditioner outputs temperature regulating air flow, and meanwhile, the second air outlet area of the cabinet air conditioner outputs optimized air flow.
Specifically, when the detection system of the cabinet air conditioner detects a target person, the optimized working condition is started. The target person may be a child, or an old person or a specific person may be set as the target person according to actual needs. (at this time, the target person may be detected and recognized by the image recognition system or the face scanning system in the detection system.)
In order to further optimize the technical scheme, the air conditioner control method further comprises the following steps:
when the detection system of the cabinet air conditioner detects a preset target (such as children and pets) and judges that the distance between the preset target and the air outlet area of the cabinet air conditioner is smaller than a preset value, the second fan 4 and the first fan 1 stop rotating; (at this time, the detection system can detect and recognize the preset target through the infrared camera or the distance sensor.)
When the distance between the preset target and the air outlet area of the cabinet air conditioner is larger than the preset value, the second fan 4 and the first fan 1 resume rotation.
The operation of the cabinet air conditioner is illustrated by taking an auxiliary system as an air purifying system.
Referring to fig. 10, when the remote controller sends out an air optimizing start instruction, or when the air conditioner detection system detects that there is a child, or when the indoor air PM2.5>80, the cabinet air conditioner automatically starts the above optimizing working conditions, namely: the lifting mechanism controls the second fan 4 to ascend and then be in transmission connection with the first fan 1, and synchronously rotates, and the air purification system is started.
Referring to fig. 11, when the remote controller sends out an air optimization closing instruction, or the air conditioner detection system detects that a child/pet is approaching, or the indoor air PM2.5 is less than 50, the cabinet air conditioner automatically closes the above optimization working conditions, namely: the second fan 4 stops rotating with the first fan 1, and the second fan 4 is disconnected (reset) from the first fan 1 after being moved down.
When the lifting mechanism is a cam lifting mechanism, during the above-mentioned optimization and resetting process, the rotation process of the cam can be seen in fig. 12 (the "motor" in fig. 12 is specifically the second motor 7 described above) and fig. 13. In this process, the motor rotates forward by N pulses, so that the second fan 4 is in driving connection with the first fan 1, but in order to ensure that a proper pretightening force exists between the second fan 4 and the first fan 1, the motor needs to rotate forward by N pulses and then continue to rotate forward by N pulses. When the remote controller gives out a stop instruction or is electrified after forced stop, the cam lifting mechanism controls the second fan 4 to move downwards and then disconnect (reset) from the first fan 1.
