Detailed Description

The utility model discloses a cabinet air conditioner, which can provide power for the cabinet air conditioner in various functional states through a motor, and is beneficial to meeting the market demands of function diversification, equipment integration and miniaturization of air conditioner products.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and 2, an air conditioner cabinet according to an embodiment of the present invention includes a housing, a first fan 1, a second fan 4, an electromagnet, and a motor for driving the first fan 1 to rotate around its axis. Wherein:

the shell comprises an upper functional area and a lower functional area, and the first fan 1 and the second fan 4 are respectively and rotatably arranged in the upper functional area and the lower functional area;

the electromagnet is used for controlling the second fan 4 to lift axially;

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 descends to the second height position, the transmission connection relationship between the second fan 4 and the first fan 1 is released.

Therefore, it can be seen that, in the cabinet air conditioner provided in the embodiment of the present invention, not only the first fan 1 and the second fan 4 are provided, but also the transmission connection and disconnection between the first fan 1 and the second fan 4 can be controlled by the electromagnet (i.e. the transmission connection relationship is released):

when the transmission connection relationship between the first fan 1 and the second fan 4 is released, the 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 fan and the second fan can be driven by the motor to synchronously rotate, so that the working requirements of the upper functional area and the lower functional area are met simultaneously.

Therefore, in the cabinet air conditioner provided by the embodiment of the utility model, the power can be provided for the cabinet air conditioner in various functional states through one motor, so that not only is the function diversification of an air conditioner product realized, but also the market demands of equipment integration and miniaturization are favorably met.

It should be noted that the "transmission connection" referred to herein may be realized by a gear transmission connection structure, or may be realized by a circumferential limiting structure, which will be described below. In the specific implementation:

if the gear transmission connection structure is adopted to realize the transmission connection between the first fan 1 and the second fan 4, then: the term "transmission connection" means that a plurality of gears are engaged with each other to make the first fan 1 drive 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/radially displace through a driving mechanism.

If the circumferential limiting structure is used to realize the transmission connection between the first fan 1 and the second fan 4, then: the transmission connection is that the shaft end and the shaft sleeve are inserted with each other and then are circumferentially clamped and limited so that the first fan 1 drives the second fan 4 to synchronously rotate; the "transmission connection release" means that the shaft end and the sleeve are disengaged from each other to allow the first fan 1 to rotate alone.

In specific implementation, please refer to fig. 2 and 3, the cabinet air conditioner is further provided with a bottom support plate 6 and a lower sliding cover 9, wherein:

the bottom supporting disk 6 is fixedly connected with the shell, and the bottom supporting disk 6 is provided with a vertical guide cylinder;

the lower end shaft of the second fan 4 is rotationally connected with the lower sliding cover 9;

the electromagnet and/or the lower sliding cover 9 are/is arranged in the vertical guide cylinder, and the electromagnet is used for controlling the lower sliding cover 9 to move up and down so as to drive the second fan 4 to axially lift through the lower sliding cover 9.

Specifically, the electromagnet includes a first magnet 81 and a second magnet 82, and an elastic member 7 located between the first magnet 81 and the second magnet 82. Wherein, the first magnet 81 is fixedly arranged in the vertical guide cylinder; the second magnet 82 is located above the first magnet 81, and controls the lower slide cover 9 to move up and down.

When the electromagnet is energized, the second magnet 82 moves upward relative to the first magnet 81, and the second fan 4 is lifted to the first height position. (at this time, the distance between the first and second magnets 81 and 82 is a first preset distance)

When the electromagnet is de-energized, the second magnet 82 moves downward relative to the first magnet 81 and the second fan 4 is lowered to the second height position. (at this time, the distance between the first magnet 81 and the second magnet 82 is a second predetermined distance which is smaller than the first predetermined distance)

Preferably, the first magnet 81 and the second magnet 82 are both magnets of annular structure. Moreover, the upper part of the lower sliding cover 9 is provided with a slotted hole for installing a bottom bearing 11 (such as a ball bearing), and the lower end shaft of the second fan 4 is in interference fit with the inner ring of the bottom bearing 11, so that the rotary connection between the second fan 4 and the lower sliding cover 9 can be realized through the bottom bearing 11; the lower portion of the lower slide cover 9 is provided with a guide shaft which is located in the central holes of the first and second magnets 81 and 82.

Therefore, in the cabinet air conditioner, the bottom supporting disc 6 can radially limit 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 to slide up and down in the axial direction by the lower slide cover 9. As shown in fig. 4, when the second fan 4 ascends and is in transmission connection with the first fan 1, the lower sliding cover 9 slides upwards relative to the bottom supporting disc 6; as shown in fig. 5, when the second fan 4 is disconnected from the first fan 1 after being lowered, the lower sliding cover 9 slides downward with respect to the bottom support plate 6. Moreover, the first magnet 81 and the second magnet 82 in the annular structure and the vertical guide cylinder of the bottom support disk 6 can both play a guiding role in the up-and-down movement of the lower sliding cover 9, so as to ensure that the second fan 4 is accurately connected with the first fan 1.

But not limited thereto, in other embodiments, the bottom support disk 6 may be provided with other structures, such as thicker support structures, or tapered support structures, or other structures having the same function.

In a preferred 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 limiting structure, and the circumferential limiting structure comprises a limiting shaft end and a limiting shaft sleeve. If the lower end shaft of the first fan 1 is a limiting shaft end, the upper end shaft of the second fan 4 is a limiting shaft sleeve; if the upper end shaft of the second fan 4 is a limiting shaft end, the lower end shaft of the first fan 1 is a limiting shaft sleeve. Specifically, please refer to fig. 6 to 8:

a plurality of circumferential limiting bulges 101 are arranged on the outer wall of the limiting shaft end at intervals along the circumferential direction, and the end part of each circumferential limiting bulge 101 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 plurality of circumferential limiting clamping grooves 201 correspond to the plurality of circumferential limiting protrusions 101 one to one and are matched in structure;

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 towards the limiting shaft sleeve, if the circumferential limiting protrusion 101 of the limiting shaft end is not aligned with the circumferential limiting slot 201 of the limiting shaft sleeve, but falls on the variable-profile guide surface 202 between adjacent circumferential limiting slots 201, under the guiding action of the variable-profile guide surface 202, relative rotation occurs between the limiting shaft end and the limiting shaft sleeve (assuming that the limiting shaft sleeve is not moved, the moving direction of the limiting shaft end is as shown by an arrow in fig. 8: the limiting shaft end moves downwards while rotating), so that the circumferential limiting protrusion 101 gradually slides into the circumferential limiting slot 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.

In an embodiment, referring to fig. 1, fig. 2, fig. 4, and fig. 5, 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 connected 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 to the upper sliding cover 12.

Specifically, the upper slide cover 12 is provided with an upper cover passage hole, and an upper bearing 10 (a ball bearing may be specifically used) is provided between the upper end shaft of the second fan 4 and the upper cover passage hole, so that the rotational connection between the second fan 4 and the upper slide cover 12 is achieved by the upper bearing 10.

Therefore, in the cabinet air conditioner, the first middle spacer 3 and the upper bearing 10 can limit the upper end shaft of the second fan 4 in the radial direction, so that the fan is prevented from shaking excessively; the second fan 4 can be slid up and down in the axial direction by the upper slide cover 12. As shown in fig. 4, when the second fan 4 ascends and is in transmission connection with the first fan 1, the upper sliding cover 12 slides upwards 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 middle spacer 3.

Referring to fig. 1 and 2, in an 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 is provided with a second through hole, and a lower end shaft of the first fan 1 is rotatably sleeved in the second 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 second through hole to act as an axial support 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 second through hole, so that the lower end shaft of the first fan 1 is rotatably connected to the second through hole of the second middle spacer 2 through the third bearing 13.

Specifically, the first middle spacer 3 is a water pan, and the second middle spacer 2 is an air duct chassis. However, the present invention is not limited to this, and in other embodiments, a person skilled in the art may adopt other structures as the first middle spacer 3 and the second middle spacer 2.

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 components generally comprise a compressor, an evaporator, a condenser and the like; the air outlet direction of the first fan 1 corresponds to the position of the first air outlet area of the shell. When the refrigerating system works, the first air outlet area outputs temperature-adjusting airflow.

Specifically, the lower functional area in the cabinet air conditioner is provided with an auxiliary system, and the auxiliary system is any one of an air purification system, a sterilization system and a humidification system, or a combination of two of the air purification system, the sterilization system and the humidification system, or all of the air purification system, the sterilization system and the humidification system; the air outlet direction of the second fan 4 corresponds to the position of the second air outlet area of the shell. This second outlet zone outputs optimized (i.e. cleaned/sterilised/humidified) air when the system is assisted.

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 the housing panel of the cabinet air conditioner. And a first driving mechanism and a second driving mechanism are further arranged in the shell, the first driving mechanism is used for controlling the air guide plate of the first air outlet area to be opened and closed independently, and the second driving mechanism is used for controlling the air guide plate of the second air outlet area to be opened and closed independently. When a functional system (such as a refrigeration system) in the upper functional area works, the first driving mechanism controls the air deflector of the first air outlet area to be opened; when a functional system (such as an air purification system/a sterilization system/a humidification system) in the lower functional zone works, the second driving mechanism controls the air deflector of the second air outlet zone to be opened.

Furthermore, a protecting 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 above-mentioned cabinet air conditioner, the first middle spacer 3, the second middle spacer 2, and the bottom support plate 6 are fixedly connected to the column 5 inside the casing, respectively. The joint between the first middle spacer 3 and the upright post 5, the joint between the second middle spacer 2 and the upright post 5, and the joint between the bottom support plate 6 and the upright post 5 are fastened and connected by screws 15, and vibration isolating pads 14 are sleeved on the screws 15. The specific mounting structure of the vibration isolator 14 and the screw 15 is shown in fig. 9.

In addition, the embodiment of the utility model 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 removed, the temperature adjusting system is in a working state, and the motor drives the first fan 1 to rotate so as to enable the first air outlet area of the cabinet air conditioner to output temperature adjusting air flow;

when the cabinet air conditioner is in the optimized working condition, the second fan 4 is controlled to axially ascend through the electromagnet so as to enable the second fan 4 to be in transmission connection with the first fan 1, the temperature adjusting system and the auxiliary system are both in working states, the motor drives the first fan 1 and the second fan 4 to synchronously rotate so as to enable the first air outlet area of the cabinet air conditioner to output temperature adjusting 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 above-mentioned 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. (in this case, the target person can be detected and recognized by the image recognition system or the face scanning system in the detection system)

In order to further optimize the above technical solution, the air conditioner control method further includes:

when a 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 an 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; (in this case, the detection system may detect and recognize a predetermined target by using an infrared camera or a 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 are rotated again.

The following takes the auxiliary system as an air purification system as an example to illustrate the operation process of the cabinet air conditioner.

Referring to fig. 10, when the remote controller sends an air optimization start instruction, or the air conditioner detection system detects a child, or the indoor air PM2.5>80, the cabinet air conditioner automatically starts the above-mentioned optimization conditions, that is: the second fan 4 is controlled by the electromagnet to ascend and then is 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 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 conditions, that is: the second fan 4 and the first fan 1 stop rotating, and the second fan 4 is disconnected (reset) from the first fan 1 after moving downwards.

In a specific embodiment, in the optimized working condition and the resetting process, the second motor 7 rotates in the forward direction by N pulses, that is, the second fan 4 is in transmission 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 second motor 7 continues to rotate in the forward direction by N pulses after rotating in the forward direction by N pulses. When the remote controller sends a stop instruction or forcibly stops, the second fan 4 moves down and then is disconnected (reset) from the first fan 1.
