[0050] The utility model provides a vertical air conditioner indoor unit. The vertical air conditioner indoor unit is the indoor part of a split vertical air conditioner or the indoor terminal model of a central air conditioner, and is used to adjust the indoor air, specifically, including adjusting the temperature, humidity, air quality of the air, humidifying, dehumidifying, introducing fresh air, etc. The air conditioner can be composed of an evaporator, a condenser, a compressor, a throttling device and other necessary components to form a vapor compression refrigeration cycle system, so as to output cold air / hot air through a fan to achieve cooling and heating of the indoor environment.

[0051] Figure 1 It is a structural schematic diagram of a vertical air-conditioning indoor unit according to an embodiment of the utility model; Figure 2 yes Figure 1 The schematic diagram of the vertical air conditioner indoor unit shown is when the slide plate 14 is in the open position; Figure 3 yes Figure 1 A schematic diagram of the structure of the slide plate 14 and the driving mechanism 80 in the illustrated embodiment.

[0052] like Figure 1 and Figure 2 As shown, the vertical air conditioner indoor unit of the embodiment of the utility model may generally include a housing 10, a slide plate 14 and at least one driving mechanism 80. The housing 10 defines a storage space for accommodating the main components of the vertical air conditioner indoor unit. The housing 10 is provided with an opening 12 connecting the inner and outer spaces of the housing 10. The function of the opening 12 can be air intake, air outlet, air inlet and outlet, or a take-and-drop opening, and the user can take and drop the functional modules inside the housing 10 through the opening 12, such as filtering, water washing, fresh air, purification, control and the like modules. The utility model does not limit the function of the opening 12. Figure 1 and Figure 2 In the illustrated embodiment, the opening 12 is an air outlet for blowing airflow such as heat exchange airflow inside the housing 10 to the indoor environment to regulate the indoor air.

[0053] The slide plate 14 is installed on the housing 10 so as to be translatably movable between a closed position and an open position, and is used to open and close the opening 12. Specifically, the slide plate 14 can be allowed to stay in the closed position and the open position. In the closed position, the opening 12 is closed. Figure 1 In the open position, the opening 12 is opened, such as Figure 2 Of course, the slide plate 14 can also be stopped at other positions between the closed position and the open position, so that the opening 12 is in a partially open state, thereby adjusting the opening degree of the opening 12. If the opening 12 is used for air intake / air outlet, the air intake / air outlet volume can be adjusted thereby.

[0054] The driving mechanism 80 is mounted on the housing 10 and is used to drive the slide plate 14 to translate between the closed position and the open position. The number of the driving mechanism 80 can be one or more. Figure 3 As shown, there are two driving mechanisms 80, which respectively drive the opposite ends of the slide plate 14. When there are multiple driving mechanisms 80, the multiple driving mechanisms 80 preferably act synchronously so that the movement of the slide plate 14 is a translational movement.

[0055] Figure 4 yes Figure 3 An exploded schematic diagram of the structure shown; Figure 5 yes Figure 4 Enlarged view of point A.

[0056] like Figure 4 and Figure 5 As shown, each driving mechanism 80 includes at least one motor 85, 86, a plurality of gears 83, 84 and a rack 82, and the plurality of gears 83, 84 rotate on a fixed axis under the drive of at least one motor 85, 86. The rack 82 is fixed to the slide 14. Specifically, the rack 82 can be directly fixed to the slide 14; or, the rack 82 can be indirectly fixed to the slide 14. That is, the rack 82 is fixed to the intermediate component, and the intermediate component is fixed to the slide 14.

[0057] Each driving mechanism 80 is configured such that: when the slide 14 is in the open position or the closed position, one gear is meshed with the rack 82; during the translation of the slide 14, the remaining gears are meshed with the rack 82 in sequence, so that the gears 83 and 84 relay to drive the rack 82 to translate. Figure 5 For example, Figure 5 The slide plate 14 is shown in the open position. In this position, the gear 84 is meshed with the rack 82. When the slide plate 14 needs to be closed, the motor 86 is started to drive the gear 84 to rotate, so that the rack 82 moves left. The rack 82 moves left until the gear 83 begins to mesh with the rack 82, and then the gear 83 rotates to drive the rack 82 to continue to move left.

[0058] In the vertical air conditioner indoor unit of the utility model embodiment, the slide plate 14 is installed on the housing 10 in a translational manner between a closed position and an open position to open and close the opening 12. Moreover, the driving mechanism 80 is a gear rack mechanism, and includes a plurality of gears 83, 84. When the slide plate 14 is in the open position or the closed position, one gear is meshed with the rack 82, and during the translation process of the slide plate 14, the remaining gears are meshed with the rack 82 in sequence to relay the translation of the rack 82, so that the length of the rack 82 can be shortened, and it is avoided that the rack 82 is too long to occupy a larger space of the housing 10 and interfere with the normal arrangement of other components. It can be seen that the shortest length of the rack 82 is slightly larger than the spacing between the two adjacent gears 83, 84, so as to ensure that when one end of the rack 82 is about to disengage from the previous gear, the other end of the rack 82 has begun to mesh with the next gear. Therefore, the more the number of gears 83, 84, the smaller the spacing between adjacent gears 83, 84, and the smaller the length of the rack 82.

[0059] In some embodiments of the present invention, Figure 5 As shown, each drive mechanism 80 may further include a plurality of motors 85, 86, and the plurality of motors 85, 86 are independently controlled, and each motor 85, 86 is connected to a gear 83, 84 to drive the gear 83, 84 to rotate on a fixed axis. Specifically, in the process of driving the slide 14 to translate, each motor 85, 86 may be rotated synchronously. Alternatively, each motor 85, 86 may be rotated asynchronously, and after the gear 83, 84 corresponding to each motor 85, 86 is meshed with the rack 82, the motor 85, 86 is started. In this way, there is no need to set additional components such as linkage gears between each gear 83, 84 to realize the rotation of each gear 83, 84, making the drive mechanism 80 simpler as a whole. Of course, in some alternative embodiments, only one motor 85, 86 may be provided, and the motor 85, 86 drives all the gears 83, 84 to rotate synchronously through a transmission mechanism such as a gear mechanism.

[0060] Figure 6 yes Figure 5 The rack 82 , the first mounting plate 810 and the connecting plate 140 are shown in another perspective.

[0061] In some embodiments of the present invention, Figure 3 , Figure 5 and Figure 6As shown, each driving mechanism 80 also includes a mounting base 81. The mounting base 81 is fixed to the housing 10, and includes a first mounting plate 810 and a second mounting plate 820, which are arranged at intervals and fixed to each other, and the two surfaces facing each other are respectively provided with first slide grooves 801. That is, the mounting base 81 has two first slide grooves 801 facing each other. Part of the rack 82 extends between the first mounting plate 810 and the second mounting plate 820, and the rack 82 has at least one positioning portion 821, 822 on both sides facing the first mounting plate 810 and the second mounting plate 820, respectively, and each positioning portion 821, 822 on each side of the rack 82 is inserted into a first slide groove 801, so that the translation direction of the rack 82 is limited by the first slide groove 801. The portion of the rack 82 retained outside the mounting base 81 is used to directly or indirectly connect to the slide plate 14. In this way, the degree of freedom of the rack 82 can be constrained, so that the rack 82 can only reciprocate along the first slide groove 801. The length of the first sliding groove 801 also limits the reciprocating translation range of the rack 82 .

[0062] Specifically, Figure 6 As shown, the second mounting plate 820 can be used to be mounted on the housing 10, and the edge of the surface of the first mounting plate 810 facing the second mounting plate 820 has a protruding ridge 816. The ridge 816 abuts against the surface of the second mounting plate 820, and the ridge 816 is connected to the second mounting plate 820 by screws, so that there is a gap between the main body of the first mounting plate 810 and the second mounting plate 820, allowing part of the rack 82 to extend into the gap.

[0063] Furthermore, in some embodiments, Figure 5 and Figure 6 As shown, the two facing surfaces of the first mounting plate 810 and the second mounting plate 820 are respectively provided with second slide grooves 802 facing each other. That is, the mounting base 81 has two second slide grooves 802 facing each other. At least one rotatable support wheel 829 is mounted on the rack 82, and each support wheel 829 is inserted into the two second slide grooves 802 to roll along the two second slide grooves 802. The number of the support wheels 829 is preferably multiple.

[0064] In this embodiment, the mounting base 81 utilizes two opposite first slide grooves 801 to cooperate with the positioning parts 821 and 822 of the rack 82 to achieve positioning and translational guidance of the rack 82, and utilizes two opposite second slide grooves 802 and the supporting wheels 829 of the rack 82 to achieve support for the rack 82 and the skateboard 14, and make the translation of the skateboard 14 more labor-saving.

[0065] The second slide groove 802 can be located between the first slide groove 801 and the slide plate 14. That is, the support wheel 829 is closer to the slide plate 14 than the positioning parts 821 and 822, so that the support wheel 829 bears more of the gravity of the slide plate 14 than the positioning parts 821 and 822, reducing the force on the positioning parts 821 and 822, and preventing the positioning parts 821 and 822 from being overly stressed and pressing the first slide groove 801, so that the first slide groove 801 is not smooth.

[0066] In some embodiments, Figure 5 and Figure 6 As shown, the rack 82 can be provided with a plurality of positioning portions 821, 822 on both sides facing the first mounting plate 810 and the second mounting plate 820, respectively, and the plurality of positioning portions 821, 822 on each side of the rack 82 are arranged at intervals along the length direction of the rack 82. Each positioning portion 821, 822 is a columnar structure extending vertically from the surface of the rack 82. In this embodiment, the positioning portions 821, 822 are arranged in a columnar shape and in plurality, rather than in an integral long strip shape, because the plurality of columnar positioning portions 821, 822 are less likely to get stuck, and the sliding in the first slide groove 801 is smoother and more labor-saving.

[0067] In some embodiments, Figure 5 and Figure 6 As shown, the second mounting plate 820 can be formed with a plurality of accommodating cylinders 823, 825 for accommodating a plurality of motors 85, 86, and the first mounting plate 810 can be formed with a plurality of cylinder covers 813, 815, each cylinder cover 813, 815 is covered on an accommodating cylinder 823, 825 to accommodate the motors 85, 86 and the gears 83, 84.

[0068] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the opening 12 is provided at the front side of the housing 10 to blow out the airflow in the housing, and the blown airflow is a regulated airflow such as a heat exchange airflow, a fresh airflow, a humidified airflow, a purified airflow, etc. The moving direction of the slide plate 14 is parallel to the lateral direction of the housing 10 (see FIG. Figure 1 , Figure 2 In this way, the slide plate 14 is in Figure 1 When the left side is shown, the opening 12 is closed. The slide plate 14 is in Figure 2 When the right side is shown, the opening 12 is opened so that the air can flow out of the opening 12. Of course, the slide plate 14 can be adjusted to Figure 1 and Figure 2 The different positions between the two sides can be used to adjust the opening degree of the opening 12, thereby adjusting the air volume. Of course, in some alternative embodiments, the moving direction of the slide plate 14 can also be forward and backward movement, which will not be described here.

[0069] like Figure 2 and Figure 3 As shown, the number of the at least one driving mechanism 80 can be two, the two driving mechanisms 80 are arranged in the up-down direction, and the two racks 82 are directly or indirectly connected to the upper and lower ends of the slide plate 14, respectively, so that the slide plate 14 is more stable.

[0070] Furthermore, if Figure 2 and Figure 3 As shown, the top and bottom of the slide plate 14 can be provided with connecting plates 140 respectively. The two driving mechanisms 80 are located inside the housing 10. The housing 10 is provided with two long strip-shaped clearance holes 171 and 181 extending in the transverse direction of the housing 10. Each connecting plate 140 extends into the housing 10 through one of the long strip-shaped clearance holes 171 and 181 to connect with a rack 82. Figure 2 As shown, the driving mechanism 80 at the upper position can be located below the top cover 17 of the housing 10, and a long strip-shaped clearance hole 171 is opened on the top cover 17. The driving mechanism 80 at the lower position is located behind the front panel 18 of the housing 10, and a long strip-shaped clearance hole 181 is opened on the front panel 18.

[0071] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 7 As shown, the front side of the casing 10 has an air outlet area 101 (an area surrounded by four points ABED) and a non-air outlet area 102 (an area surrounded by four points BCFE) arranged along the transverse direction of the casing 10, and the opening 12 is arranged in the air outlet area. The vertical air conditioner indoor unit also includes a plurality of cross-flow fans, which are arranged in the casing 10 in a vertical direction to blow the air flow inside the casing 10 outward through the corresponding sub-openings 12. The operation of each cross-flow fan 30 is independently controlled. A side air outlet 13 is provided on the lateral side of the casing 10 close to the air outlet area 101, so that when each cross-flow fan 30 is turned on, the side air outlet 13 discharges air toward the lateral side. For example, Figure 1 to Figure 2 In the illustrated embodiment, the air outlet area 101 is disposed on the left side of the non-air outlet area 102 , and the side air outlet 13 is located on the left side of the housing 10 .

[0072] In the existing vertical air conditioner indoor unit, whether it is a circular air outlet or a rectangular air outlet, it is arranged in the horizontal center of the housing 10, so that the front shape of the housing 10 forms a bilaterally symmetrical shape, which has become a fixed mindset. However, the utility model makes the air outlet (opening 12) offset, and the position is novel and unique, making the product more competitive in appearance. Since the non-air outlet area has a complete strip area from the top to the bottom of the housing 10, it is convenient to carry out various decorative designs.

[0073] In addition, the vertical air conditioner indoor unit of the utility model is provided with a plurality of cross-flow fans, and the air supply mode is adjusted by adjusting the number of cross-flow fans turned on. Moreover, the side air outlet 13 is arranged opposite to all the cross-flow fans, and the slide plate 14 can open and close the opening 12. In this way, when the vertical air conditioner indoor unit is turned off, a slide plate 14 and a side air outlet 13 are exposed, and the appearance is more complete and concise.

[0074] Moreover, the vertical air conditioner indoor unit of the embodiment of the utility model has a plurality of cross-flow fans 30 arranged in the vertical direction. In this way, the vertical air conditioner indoor unit can choose to open all or part of the cross-flow fans 30 as needed, making the air supply mode more diverse and enriching the user's choice.

[0075] For example, when the air conditioner is in cooling mode, since the cold air has a high density and tends to sink, the cross-flow fan 30 located at the top can be turned on to allow the cold air to first fill the upper area of ​​the indoor space, and then sink downward under its own gravity to fill the entire room. When the air conditioner is in heating mode, since the hot air has a low density and tends to rise, the cross-flow fan 30 located at the bottom can be turned on to allow the hot air to first fill the bottom area of ​​the indoor space, and then rise to fill the entire room.

[0076] In some embodiments of the present invention, Figure 7 As shown, the vertical air conditioner indoor unit also includes a plurality of air guide devices 50, each of which is matched with a cross-flow fan 30. Specifically, each air guide device 50 includes a plurality of transversely arranged air guide plates 51. Each air guide plate 51 can rotate around a vertical axis to adjust the left and right air outlet angles of the opening 12.

[0077] In some embodiments of the present invention, Figure 7 As shown, the vertical air conditioner indoor unit also includes a swing assembly 60. The swing assembly 60 is configured to controllably make its multiple swing blades swing synchronously to synchronously adjust the up and down air outlet angles of the opening 12, that is, to adjust the angle between the air outlet airflow and the horizontal plane. In this embodiment, multiple cross-flow fans 30 share a swing assembly 60, but each cross-flow fan 30 is not matched with a swing assembly. This is because the designers took into account that the embodiment of the utility model already has multiple cross-flow fans 30 arranged up and down, and the distribution of the air outlet airflow in the height direction of the indoor space can be adjusted by opening and closing multiple cross-flow fans 30. Therefore, the role of the swing blade assembly mainly used for up and down swinging is weakened. If each cross-flow fan 30 is matched with a swing assembly, each swing assembly needs to be provided with a motor, and each swing assembly needs to be independently controlled, which is more expensive and the control logic is more complicated. In this embodiment, only one swing assembly 60 is configured, which can save costs and simplify control.

[0078] like Figure 7As shown, the indoor unit of the vertical air conditioner also includes an indoor heat exchanger 20. The indoor heat exchanger 20 may include a plurality of sub-heat exchangers 21, each of which corresponds to a cross-flow fan 30. The plurality of sub-heat exchangers 21 may be connected to a vapor compression refrigeration cycle system in parallel. The air conditioner determines whether to enable each sub-heat exchanger 21 according to the opening and closing conditions of each cross-flow fan 30. The vapor compression refrigeration cycle system may control whether the refrigerant flows through each sub-heat exchanger 21 through a plurality of solenoid valves. The specific principle and structure are well known to those skilled in the art and will not be described in detail here.

[0079] like Figure 5 As shown, the housing 10 is used to accommodate the main components of the vertical air conditioner indoor unit, including a cross-flow fan 30, an indoor heat exchanger 20, a controller, etc. The indoor heat exchanger 20 and the throttling device are connected to the compressor, the outdoor heat exchanger and other refrigeration elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. The compressor is usually a rolling rotor compressor. The throttling device may include a capillary tube and an electronic expansion valve. For a heat pump air conditioner, the vapor compression refrigeration cycle system also includes a four-way valve for switching the air conditioner between a cooling mode and a heating mode.

[0080] For a heat pump air conditioner, in cooling mode, the heat exchanger plays the role of an evaporator. In heating mode, the indoor heat exchanger 20 plays the role of a condenser. The casing 10 may be provided with an air inlet 11 for introducing indoor air. The casing 10 is also defined with an air duct. Under the action of the cross-flow fan 30, the indoor air enters the interior of the casing 10 through the air inlet 11, and after completing forced convection heat exchange with the indoor heat exchanger 20, a heat exchange airflow is formed, which is guided by the air duct and blown out from the outlet of the air duct. The casing 10 is usually in an upright columnar shape as a whole, and its cross-section may be square, rectangular, cylindrical, elliptical or other shapes. The air inlet 11 is usually arranged at the back of the casing 10.
