Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to a cabinet air conditioner with reversible air outlet function. Background Technology

[0002] In existing cabinet-type air conditioner indoor units, reversible airflow can be achieved by adjusting the fan direction or the position of the deflector; that is, air can enter from the upper vent and exit from the lower vent, or vice versa, to meet various airflow needs. A filter is fixedly installed at the upper vent. When air enters from the upper vent, the filter can filter the incoming air, improving airflow quality; however, when air exits from the upper vent, the filter provides resistance to the outflow, affecting the air volume. Furthermore, when the upper vent switches from intake to exhaust, dust on the filter can enter the room, reducing indoor air quality. Utility Model Content

Detailed Implementation

[0058] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0059] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The singular forms “a,” “said,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise; “multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0060] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0061] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0062] In existing cabinet-type air conditioner indoor units with reversible air outlets, a filter is installed at the top air outlet. When air is drawn in from the top air outlet, the filter can filter the incoming air and improve the air quality. However, when air is discharged from the top air outlet, the filter provides resistance to the outgoing air, affecting the air volume. At the same time, when the top air outlet switches from air inlet to air outlet, dust on the filter will enter the room, reducing indoor air quality.

[0063] This utility model creatively provides a cabinet air conditioner with reversible air outlet function, including an indoor unit and a filter device. The upper side of the indoor unit has an upper air outlet and the lower side has a lower air outlet. The indoor unit is provided with a bottom air inlet and top air outlet mode where air enters from the lower air outlet and exits from the upper air outlet, and a top air inlet and bottom air outlet mode where air enters from the upper air outlet and exits from the lower air outlet. The filter device includes a filter screen.

[0064] A filter device is installed at the air vent. The filter is configured such that when the indoor unit is in the bottom air intake and top air outlet mode, the filter is in a non-filtering state, and at least part of the air outlet does not flow through the filter, so the filter does not affect the air outlet performance. When the indoor unit is in the top air intake and bottom air outlet mode, the filter is in the filtering state, and the filter can filter the air intake at the air vent to improve the air intake quality.

[0065] like Figures 1 to 2b As shown, this embodiment provides a cabinet air conditioner with reversible airflow function, including an indoor unit 1. An upper air vent 112 is formed on the upper side of the indoor unit 1, and a lower air vent 114 is formed on the lower side of the indoor unit 1. The indoor unit 1 has a bottom-inlet, top-outlet airflow configuration where air enters through the lower air vent 114 and exits through the upper air vent 112, and a top-inlet, bottom-outlet airflow configuration where air enters through the upper air vent 112 and exits through the lower air vent 114. The cabinet air conditioner has a cooling mode and a heating mode. When the cabinet air conditioner is in cooling mode, the indoor unit 1 operates in the bottom-inlet, top-outlet airflow configuration; when the cabinet air conditioner is in heating mode, the indoor unit 1 operates in the top-inlet, bottom-outlet airflow configuration.

[0066] like Figures 3 to 6 As shown, the cabinet air conditioner also includes a filter device 2, which includes a filter screen 21. The filter screen 21 has a filtering state that can filter the air flowing through it and a non-filtering state that does not filter the air. When the filter screen 21 is in the filtering state, the filter screen 21 can let the air flow through it and filter the air. When the filter screen 21 is in the non-filtering state, the filter screen 21 does not cover the corresponding air vent, and the air can pass directly through the corresponding air vent without being filtered.

[0067] When a filter device 2 is installed at the air inlet 112, the filter screen 21 is configured such that: when the indoor unit 1 is in the mode of bottom air intake and top air outlet, the filter screen 21 is in a non-filtering state, and at least part of the upward airflow does not flow through the filter screen 21; when the indoor unit 1 is in the mode of top air intake and bottom air outlet, the filter screen 21 is in the filtering state.

[0068] And / or, when a filter device 2 is provided at the downdraft 114, the filter screen 21 is configured such that: when the indoor unit 1 is in the downdraft and updraft mode, the filter screen 21 is in the filtering state; when the indoor unit 1 is in the updraft and downdraft mode, the filter screen 21 is in the non-filtering state, and at least part of the downward-flowing air does not flow through the filter screen.

[0069] Depending on the air intake and exhaust method of the indoor unit 1, the filter 21 at the air intake outlet that needs to be filtered can be in a filtering state to improve the intake air quality; the filter 21 at the air exhaust outlet that needs to be filtered can be in a non-filtering state, with little or no resistance to the exhaust air, improving the exhaust effect and ensuring smooth airflow. This solves the problem in existing cabinet air conditioners where the indoor unit 1 cannot simultaneously achieve both intake air quality and exhaust air effect; the structure is simple, highly versatile, and low in cost.

[0070] Specifically, the filter screens 21 can be detachably installed at the upper air vent 112 and / or the lower air vent 114; the filter screens 21 can be installed at the corresponding air vents as needed.

[0071] The following further explains the state of the filter screen 21. The filter device 2 also includes a frame 23. A vent 231 is formed inside the frame 23. The vent 231 is connected to the air vent where the frame 23 is located. The filter screen 21 is installed at the vent 231.

[0072] When the filter screen 21 is in the filtering state, the filter screen 21 completely covers the vent 231, and the filter screen 21 can filter the air flowing through the vent 231.

[0073] When the filter screen 21 is in a non-filtering state, the filter screen 21 is located on one side of the vent 231. Some of the air flowing through the vent does not flow through the filter screen 21, and the filter screen 21 has little impact on the airflow.

[0074] When a filter device 2 is installed at the upwind vent 112, the vent where the frame 23 is located is the upwind vent 112; when a filter device 2 is installed at the downwind vent 114, the vent where the frame 23 is located is the downwind vent 114.

[0075] Specifically, when the filter 21 is in the filtering state, the filter 21 is wavy or serrated; this increases the effective filtration area of ​​the filter 21, covering the air vent where the frame 23 is located, thereby slowing down the clogging speed of the filter 21, extending its service life, and solving the problem in existing cabinet air conditioners where the effective filtration area of ​​the filter 21 is small, the filter 21 does not filter the incoming air thoroughly, resulting in dirt on the surface of the evaporator and inside the air duct 12, and poor air quality at the indoor unit 1.

[0076] The specific structure of the filter screen 21 is described below. The filter screen 21 includes a plurality of filter sections 211 arranged sequentially along the length of the vent 231, and two adjacent filter sections 211 can be folded and connected.

[0077] When the filter screen 21 is in the filtering state, the filter surfaces of two adjacent filter sections 211 are far apart from each other, that is, the filter surfaces of two adjacent filter sections 211 are unfolded and intersect or coplanar.

[0078] When the filter screen 21 is in a non-filtering state, the filter surfaces of two adjacent filter sections 211 are close to each other, that is, the filter surfaces of two adjacent filter sections 211 are stacked.

[0079] The filter 21 is configured to switch between a filtering state and a non-filtering state by moving two adjacent filter sections 211 relative to each other in the length direction of the vent 231.

[0080] Furthermore, different filter sections 211 have different filtration levels, so that different filter sections 211 are in a filtration state, which can achieve different filtration effects; in addition, by stacking two adjacent filter sections 211 in the depth direction of the vent 231, the flowing air can be filtered twice.

[0081] The following describes the transition of filter screen 21 between filtering and non-filtering states. Filter screen 21 includes a head end and a tail end arranged opposite each other along its length. The head end of filter screen 21 is provided with a head end rod 221, and the tail end of filter screen 21 is provided with a tail end rod 2211. Adjacent filter sections 211 are connected by an intermediate rod. The extension directions of the head end rod 221, the intermediate rod, and the tail end rod 2211 are all parallel to the width direction of the vent 231. The head end rod 221 is not movable along the length of filter screen 21.

[0082] The frame 23 includes two ventilation sidewalls 232 disposed opposite to each other in the width direction of the ventilation opening 231. Each ventilation sidewall 232 has a groove 241 formed on the side facing the ventilation opening 231. The groove 241 extends from one side of the ventilation opening 231 in the length direction to the other side of the ventilation opening 231 in the length direction.

[0083] The two ends of the tail rod 2211 are slidably disposed in two grooves 241 opposite to each other in the width direction of the vent 231; when the tail rod 2211 slides along the grooves 241, the filter screen 21 can switch between a filtering state and a non-filtering state.

[0084] Furthermore, along the length of the vent 231, the intermediate rod includes a first rod 222, a second rod 223, a third rod 224, ..., the Nth rod;

[0085] The chute includes a first chute 241, a second chute 242, and a third chute 243 that are sequentially spaced apart along the depth direction of the vent 231. The extension directions of the first chute 241, the second chute 242, and the third chute 243 are all parallel to the length direction of the vent 231. The second chute 242 and the third chute 243 are connected.

[0086] The second member 223, the fourth member 225, ... the (N-1)th member and the tail rod 2211 can all be slidably disposed in the first groove 241;

[0087] When the filter screen 21 is in the filtering state, the first rod 222, the third rod 224... the Nth rod can all be slidably arranged in the second slide groove 242; when the filter screen 21 is in the non-filtering state, the first rod 222, the third rod 224... the Nth rod can all be slidably arranged in the third slide groove 243.

[0088] Where N is the total number of intermediate rods, N≥5 and N is an odd number.

[0089] Specifically, the second slide 242 and the third slide 243 are connected by a transition slide 244. Multiple transition slides 244 are provided, and the multiple transition slides 244 are arranged sequentially at intervals along the length direction of the ventilation opening 231. The multiple transition slides 244 are respectively arranged in one-to-one correspondence with the first rod 222, the third rod 224... the Nth rod.

[0090] The filter screen 21 is configured such that when the filter screen 21 switches from the filtering state to the non-filtering state, the first rod 222, the third rod 224...the Nth rod can all slide from the second slide groove 242 to the third slide groove 243 via the corresponding transition slide groove 244;

[0091] When the filter screen 21 switches from a non-filtering state to a filtering state, the first rod 222, the third rod 224, ... the Nth rod can all slide from the third slide groove 243 to the second slide groove 242 via the corresponding transition slide groove 244.

[0092] The following describes the transmission mechanism of the rods. Multiple rods are arranged sequentially at intervals along the length of the vent 231. The first rod 221 is positioned close to the starting end 245 of the first slide groove, and the last rod 2211 is positioned away from the starting end 245 of the first slide groove. When the filter screen 21 switches between the filtering state and the non-filtering state, the first rod 221 is fixed relative to the first slide groove 241, while the middle rod and the last rod 2211 slide relative to the first slide groove 241.

[0093] The filter device 2 also includes a transmission mechanism 25 and a drive motor 253. The transmission mechanism 25 includes a driving member 251 and a driven member 252. The driving member 251 and the driven member 252 are arranged on the same ventilation port sidewall 232 and are both located outside the frame 23. The driving member 251 can be controlled to rotate, and the driven member 252 can be controlled to slide. The driven member 252 is connected to the tail rod 2211 in a transmission manner, and the driving member 251 is connected to the drive motor 253 in a driving manner.

[0094] When the drive motor 253 drives the active component 251 to rotate, the driven component 252 drives the tail rod 2211 to slide, thereby allowing the filter screen 21 to switch between the filtering state and the non-filtering state.

[0095] Furthermore, a bracket 26 is provided inside the vent 231, and the first end rod 221 is detachably mounted on the bracket 26. The bracket 26 is fixed relative to the first slide groove 241. The driving member 251 is a gear, and the shaft of the gear is parallel to the width direction of the vent 231. The driven member 252 is a rack, and the extension direction of the rack is parallel to the length direction of the vent 231.

[0096] In this embodiment, N=11, the filter screen 21 includes ten filter sections 211; the intermediate rod includes a first rod 222, a second rod 223, a third rod 224, a fourth rod 225, a fifth rod 226, a sixth rod 227, a seventh rod 228, an eighth rod 229, and a ninth rod 2210 arranged sequentially along the length of the vent 231; the first end rod 221 is close to the starting end 245 of the first slide groove, and the tail end rod 2211 is far away from the starting end 245 of the first slide groove;

[0097] The second rod 223, the fourth rod 225, the sixth rod 227, the eighth rod 229, and the tail rod 2211 are all slidably disposed within the first slide groove 241; when the filter screen 21 is in the filtering state, the first rod 222, the third rod 224, the fifth rod 226, the seventh rod 228, and the ninth rod 2210 are all slidably disposed within the second slide groove 242; when the filter screen 21 is in the non-filtering state, the first rod 222, the third rod 224, the fifth rod 226, the seventh rod 228, and the ninth rod 2210 are all slidably disposed within the third slide groove 243; five transition slide grooves 244 are provided, and the five transition slide grooves 244 are respectively configured one-to-one with the first rod 222, the third rod 224, the fifth rod 226, the seventh rod 228, and the ninth rod 2210;

[0112] Furthermore, the indoor unit 1 includes a housing 11, the top wall 111 of the housing 11 has an upper air vent 112 and an opening 15 corresponding to the upper air vent 112, and the lower side of the front wall 113 of the housing 11 has a lower air vent 114 and an opening 15 corresponding to the lower air vent 114; when the filter device 2 is installed at the upper air vent 112 or the lower air vent 114, the filter device 2 is closer to the inside of the housing 11 than the outside of the housing 11.

[0113] An air duct 12 is formed inside the housing 11, and a rotatable fan blade 13 is provided inside the air duct 12; the fan blade 13 is a centrifugal fan blade.

[0114] Indoor unit 1 is configured to control the direction of the fan blades 13, which can put indoor unit 1 into a bottom air intake and top air outlet mode and a top air intake and bottom air outlet mode;

[0115] Specifically, a movable air guide plate 14 is provided at the upper air vent 112. The air guide plate 14 is closer to the outside of the housing 11 than to the inside of the housing 11. The air guide plate 14 can be controlled to open or close the upper air vent 112, or adjust the opening size and air outlet direction of the upper air vent 112 when it is in the open state. Preferably, the air guide plate 14 is rotatably arranged at the upper air vent 112. The extension direction of the air guide plate 14 is parallel to the left and right direction of the housing 11. Multiple air guide plates 14 are provided, and multiple air guide plates 14 are arranged sequentially along the front and rear direction of the housing 11. Each air guide plate 14 can be controlled to rotate independently or multiple air guide plates 14 can be controlled to rotate synchronously.

[0116] In summary, the filter 21 can be flexibly switched according to the air intake and exhaust method, taking into account both the air intake quality and the air exhaust effect, and meeting the requirement of reversible air exhaust. The filter 21 is hidden in the storage space 233, which does not affect the overall appearance of the indoor unit 1. The transmission mechanism 25 slides with the tail rod 2211, and then the second rod 223, the fourth rod 225... the (N-1)th rod all slide in the first slide groove 241, and the first rod 222, the third rod 224... the Nth rod all slide between the second slide groove 242 and the third slide groove 243, so that the filter 21 can be stably switched between the filtering state and the non-filtering state.
