Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a vertical air conditioner. Background Technology

[0002] Air conditioners are widely used for indoor temperature regulation. In existing air conditioners, cross-flow fans are generally used as the power source and are arranged in the air duct to drive the airflow. However, cross-flow fans are bulky and have a small air volume, resulting in a bulky overall air conditioner with a small air volume and weak temperature regulation effect. At the same time, in order to achieve diverse air supply in the air conditioner, air guide devices need to be installed at the air outlet of the air conditioner.

[0003] Therefore, how to select a suitable power source and air guiding device to achieve compactness, high air volume, and diverse air supply in air conditioners is a pressing challenge that needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical air conditioner to solve the technical problem of how to select a suitable power source and air guiding device to achieve the air conditioner's compact size, high air volume, and diverse air supply.

[0005] To solve the above problems, this utility model provides a vertical air conditioner, comprising:

[0006] The housing has an air inlet and a forward-facing air outlet; and,

[0007] An air supply assembly is housed within the housing. The air supply assembly includes a mixed-flow fan and a sweeping structure. The mixed-flow fan has an upwardly arranged exhaust port.

Detailed Implementation

[0027] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0028] This embodiment also provides a vertical air conditioner, such as... Figures 1-5 As shown, the device includes a housing 200 and an air supply assembly 100. The housing 200 has an air inlet 240 and a forward-facing air outlet 250. The air supply assembly 100 is housed within the housing 200 and includes a mixed-flow fan 110 and a sweeping structure 130. The mixed-flow fan 110 has an upward-facing exhaust port 114. The sweeping structure 130 includes a drive member 132 and a plurality of sweeping blades 131 disposed at the exhaust port 114. The drive member 132 is drivenly connected to the sweeping blades 131 and is configured to adjust the sweeping direction of the sweeping blades 131 to change the airflow area blown out of the front air outlet 250 in the Z-direction of the height direction.

[0029] The vertical air conditioner provided in this embodiment includes a housing 200 with an internal air duct 270 and an air supply assembly 100 that can drive airflow and adjust the direction and range of airflow. In use, the air supply assembly 100 operates and drives ambient air into the air duct 270 through the air inlet 240. After exchanging heat with the evaporator 300 within the air duct 270, the air enters the air supply assembly 100 and is accelerated by its fan blades before being blown out through the exhaust port 114. The front air outlet 250 of the housing 200 is located in the Z-direction of the height direction. With a large air outlet range, when the swing structure 130 is driven by the drive component 132 to be located in different swing directions, the airflow blown out by the mixed flow fan 110 through the exhaust port 114 can flow towards the front air outlet 250 in the corresponding direction and range under the guidance of the swing structure 130, and be blown outward through the corresponding area of ​​the front air outlet 250. Users can adjust the swing direction of the swing structure 130 according to their own needs, so that the vertical air conditioner enters the corresponding temperature adjustment mode, thereby ensuring the comfort of using the vertical air conditioner.

[0030] The use of the aforementioned air supply component 100 in this vertical air conditioner offers several advantages. Firstly, the air supply component 100 utilizes a compact, high-volume, and low-noise mixed-flow fan 110 as its power source. While ensuring the air volume and temperature regulation effect of the vertical air conditioner, it reduces the overall size of the air conditioner, minimizes its space occupation, lowers its operating noise, and improves its ease of installation and user comfort. Secondly, the air supply component 100 incorporates a sweeping structure 130 at the exhaust port of the mixed-flow fan 110. This allows it to not only serve as the power source for the air supply of the vertical air conditioner but also to simultaneously adjust the air supply direction and range, thereby achieving diverse air supply options for the vertical air conditioner. Furthermore, while ensuring the user comfort and functionality of the vertical air conditioner, it eliminates the need for a guide vane at the front air outlet 250, resulting in a simpler structure and enhanced functionality for the vertical air conditioner.

[0031] Specifically, the multiple sweeping blades 131 of the sweeping structure 130 are rotatably connected to the side wall of the exhaust port 114, and the multiple sweeping blades 131 are linked together by linkage mechanisms such as connecting rods; the driving component 132 can be a rotary driving component, such as a rotary motor, etc. The driving end of the driving component 132 is connected to one of the sweeping blades 131. When adjusting the sweeping direction, the driving component 132 drives the sweeping blade 131 to rotate, and drives all the sweeping blades 131 to rotate synchronously through the linkage mechanism, thereby realizing the adjustment of the sweeping direction; or, the driving component 132 drives the sweeping blade 131 to rotate. Component 132 can also be a telescopic drive component, such as a push rod motor. The drive end of the drive component 132 is connected to the linkage mechanism. When adjusting the sweeping direction, the drive component 132 drives the linkage mechanism to move linearly, thereby driving all the sweeping blades 131 to rotate synchronously, thus realizing the adjustment of the sweeping direction. Preferably, the sweeping blades 131 have a closed state. When the closed state is reached, the drive component 132 drives multiple sweeping blades 131 to jointly block the exhaust port 114, so as to reduce the blockage or pollution caused by dust and other substances entering the mixed flow fan 110 when in standby or off state.

[0032] In this embodiment, as Figures 2-5 As shown, the air outlet of the mixed-flow fan 110 is connected to an air guide duct 120, and the drive component 132 and multiple sweeping blades 131 are all located in the air guide duct 120. The air guide duct 120 serves as the exhaust port 114. On the one hand, the air guide duct 120 can guide the airflow direction of the mixed-flow fan 110 to improve the flexibility of the airflow direction of the mixed-flow fan 110. On the other hand, the air guide duct 120 is independent of the mixed-flow fan 110, and the existing mixed-flow fan 110 can be directly assembled with the air guide duct 120 to form the air supply assembly 100 without modifying the existing mixed-flow fan 110, thereby reducing the cost of the air supply assembly 100. At the same time, the sweeping blades 131 and the drive component 132 are all connected to the air guide duct 120, which minimizes the damage to the connection of the mixed-flow fan 110 and ensures the airtightness and smoothness of the air passage inside the mixed-flow fan 110.

[0033] In this embodiment, as Figures 2-5As shown, the outlet of the air guide duct 120 is inclined towards the front outlet 250. The air duct 270 enclosed by the housing 200 extends approximately vertically, and the air inlet 240 is arranged in the lower region of the housing 200. The air supply assembly 100 is installed in the air duct 270 at the junction of the front outlet 250 and the air inlet 240. The mixed-flow fan 110 is an annular mixed-flow fan and is arranged horizontally. The mixed-flow fan 110 is approximately coaxial with the air duct 270, and the air inlet of the mixed-flow fan 110 is located at its bottom and serves as the air intake 113. The air outlet of the mixed-flow fan 110... Port 117 is located at its top and is connected to an air guide duct 120. The air guide duct 120 extends upward and its top air outlet is inclined upward from front to back, so as to be inclined toward the front air outlet 250 of the vertical air conditioner. This ensures that the airflow blown out through the exhaust port 114 can flow to the front air outlet 250, and increases the air outlet range of the exhaust port 114 in the height direction under the air guiding effect of the sweeping structure 130, thereby ensuring the air outlet range and temperature regulation effect of the vertical air conditioner.

[0034] Specifically, such as Figure 3 As shown, the mixed-flow fan 110 is equipped with a high-speed motor 111, which has an annular flow channel 112, and a conical diffuser 115 is formed at the center of the annular flow channel 112. The outer periphery of the annular flow channel 112 is a guide ring 116, thereby forming an annular acceleration air outlet port 117. A ring of ribs 118 arranged at intervals along its circumference is also provided at the air outlet port 117 of the mixed-flow fan 110 to achieve spiral high-speed air outlet.

[0035] Specifically, in this embodiment, as Figures 2-5 As shown, the air guide duct 120 is tapered from bottom to top. The air guide duct 120 can converge the airflow blown upward by the mixed flow fan 110, and then blow it upward through its air outlet toward the front air outlet to improve the uniformity of airflow and increase the air delivery distance, thereby improving the temperature regulation effect of the vertical air conditioner.

[0036] Specifically, such as Figures 2-5As shown, the air duct 120 includes, from bottom to top, a plug-in section 121, a connecting section 122, and an air outlet section 123. The plug-in section 121 is plugged into the air outlet port of the mixed flow fan 110. The air outlet section 123 is a rectangular section, and multiple sweeping blades 131 are provided on the air outlet section 123. The connecting section 122 is smoothly connected between the plug-in section 121 and the air outlet section 122. The shape and size of the plug-in section 121 at the bottom of the air guide duct 120 are adapted to the air outlet port at the top of the mixed flow fan 110. The plug-in connection allows for convenient connection between the two, thereby improving the ease of connection between the air guide duct 120 and the mixed flow fan 110. The air outlet section 123 at the top of the air guide duct 120 is a rectangular section with a regular shape. The length direction of the air outlet section 123 is consistent with the left-right direction (Y direction) of the vertical air conditioner, and the width direction of the air outlet section 123 is consistent with the front-back direction (X direction) of the vertical air conditioner. The multiple sweeping blades 131 of the sweeping structure 130 extend in the left-right direction and are arranged at intervals in the front-back direction (X direction) to improve the ease of arrangement and neatness of the sweeping blades 131, and to make the sweeping range of the sweeping blades 131 similar to the air outlet range of the front air outlet 250.

[0037] In this embodiment, as Figures 1-3 As shown, the front air outlet 250 includes a first front air outlet 251 and a second front air outlet 252 disposed on the front panel 231 of the housing 200. The first front air outlet 251 is located in the upper region of the front panel 231, and the extension height of the first front air outlet 251 is not less than 1 / 3 of the total height of the front panel 231. The first front air outlet 251 corresponds to the first sweeping range of the sweeping structure 130. The second front air outlet 252 is located below the first front air outlet 251, and the second front air outlet 252 corresponds to the second sweeping range of the sweeping structure 130.

[0038] like Figure 1 and Figure 2 As shown, the housing 200 includes a top plate 210, a bottom plate 220, and a side panel 230 surrounding the two. The side panel 230 specifically includes a front panel 231 and an arc-shaped rear panel 232. The first front air vent 251 is located in the upper region of the front panel 231 and has a large air outlet range along the height direction. When the user needs air outlet in a large upper region, the drive unit 132 can be adjusted to drive the sweeping blades 131 to the first sweeping range. Then, the airflow blown out through the exhaust port 114 can be blown out towards the first front air vent 251 with a large height range under the guiding action of the sweeping blades 131.

[0039] The second front air vent 252 is located in the area near the center of the front panel 231. Its air outlet position is low. When the user needs air to be vented from the center area, the drive unit 132 can be adjusted to drive the sweeping blades 131 to the second sweeping range. Then, the airflow blown out through the exhaust port 114 can be blown out towards the second front air vent 252 at a low position under the guiding effect of the sweeping blades 131.

[0040] Specifically, in this embodiment, the upper region of the front panel 231 is a zero-wind plate region, which has multiple dispersed zero-wind holes 253a, each forming a first front air vent 251. The first front air vent 251 is in a zero-wind form. Specifically, multiple dispersed zero-wind holes 253a can be opened in the upper region of the front panel 231, or an opening can be made in the upper region of the front panel 231, and the zero-wind plate 253 with zero-wind holes 253a can be sealed at the opening. All zero-wind holes 253a together form the first front air vent 251.

[0041] Corresponding to the zero-wind configuration of the first front air vent 251, in this embodiment, as... Figure 4 As shown, the vertical air conditioner has a zero-wind mode. In the zero-wind mode, the sweeping structure 130 is in the first sweeping range, which is upward and forward. When the user needs comfortable, quiet air with a large air outlet range and high temperature regulation effect, they can adjust the drive component 132 to drive the sweeping blades 131 to the first sweeping range, which is upward and forward, so that the vertical air conditioner enters the zero-wind mode. Then, the airflow blown out through the exhaust port 114 can flow upward and forward to the area where the first front air outlet 251 is located under the guidance of the sweeping blades 131. When the airflow passes through multiple zero-wind holes 253a, it can be dispersed and processed, becoming a zero wind with a lower flow velocity and better noise effect, and blown forward. The large zero-wind air outlet range can ensure that the vertical air conditioner has a high temperature regulation effect.

[0042] Corresponding to the low-position air outlet of the second front air vent 252, in this embodiment, as Figure 3 As shown, the vertical air conditioner has a heating mode. In the heating mode, the sweeping structure 130 is the second sweeping range facing forward. The second front air vent 252 is an open type. When the user needs to quickly adjust the indoor environment for heating, they can adjust the drive component 132 to drive the sweeping blades 131 to the second sweeping range, so that the vertical air conditioner enters the heating mode. Then, the airflow blown out through the exhaust vent 114 can flow forward to the area where the second front air vent 252 is located under the guidance of the sweeping structure 130, and blow out forward at a lower position through the second front air vent 252, thereby achieving rapid heating adjustment of the indoor environment.

[0043] In this embodiment, as Figure 3As shown, the rear end of the second front air outlet 252 is connected to an air collecting duct 260. Along the front-to-back direction, the air collecting duct 260 is flared and extends upwards at an angle. The rear end of the air collecting duct 260 is flared and adjacent to the front side of the exhaust outlet 114, thereby increasing the air intake range of the air collecting duct 260 and ensuring that all the airflow blown out of the exhaust outlet 114 can enter the air collecting duct 260. This ensures the airflow volume through the second front air outlet 252 in heating mode, thus ensuring the heating regulation effect of the vertical air conditioner. Simultaneously, the air collecting duct 260 slopes downwards from back to front. The airflow entering the air collecting duct 260 is guided by the air collecting duct 260 and blown downwards through the second front air outlet 252, allowing the lighter hot air to be quickly blown towards the ground, further improving the rapid heating regulation of the indoor environment.

[0044] like Figure 3 As shown, the exhaust port 114 is inclined upward from front to back. When the sweeping blades 131 are arranged approximately horizontally, the sweeping structure 130 reaches the second sweeping range, and the airflow blown out through the exhaust port is blown forward approximately horizontally into the air collection duct 260.

[0045] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the front air outlet 250 includes, in addition to the first front air outlet 251 and the second front air outlet 252, an annular top air outlet 280. The annular top air outlet 280 is located between the first front air outlet 251 and the top plate 210 of the housing 200, and extends in a ring shape along the circumference of the housing 200. The annular top air outlet 280 corresponds to the third sweeping range of the sweeping structure 130. The annular top air outlet 280 is connected to the air duct 270. Specifically, the annular top air outlet 280 can be located in the top area of ​​the side panel 230, or the top of the top plate 210 and the top of the side panel 230 can be connected by a connecting foot 211, and the gap between the top plate 210 and the side panel 230 forms the annular top air outlet 280.

[0046] Corresponding to the high-position air outlet of the annular top vent 280, in this embodiment, such as Figure 5 As shown, the vertical air conditioner has a cooling mode. In cooling mode, the sweeping structure 130 is the upward-facing third sweeping range. The annular top air vent 280 is an annular opening located on the side of the casing 200. When the user needs to quickly cool and adjust the indoor environment, they can adjust the drive component 132 to drive the sweeping blades 131 to the third sweeping range, such as... Figure 5As shown, when the sweeping blades 131 are arranged upwards, the sweeping structure 130 reaches the third sweeping range, causing the vertical air conditioner to enter the cooling mode. The airflow blown out through the exhaust port 114, under the guidance of the sweeping structure 130, can flow upwards to the top of the air duct 270, and then blow outwards in a wide circumferential direction through the annular top air outlet 280, achieving rapid cooling and regulation of the indoor environment. Among them, the exhaust port 114 is tilted forward, and the airflow to the front of the air duct 270 is greater than the airflow to the rear of the air duct 270. Correspondingly, the air volume in the front area of ​​the annular top air outlet 280 is greater than the air volume in the rear area, so as to adapt to the effective cooling of the front area when the vertical air conditioner is conventionally arranged against the wall.

[0047] In this embodiment, as Figure 1 and Figure 5 As shown, a downward-protruding guide protrusion 212 is provided in the central area of ​​the bottom of the top plate 210. The guide protrusion 212 is sloping outwards in an arc shape from its center, and the side wall of the guide protrusion 212 is smoothly connected to the bottom surface of the top plate 210. In cooling mode, when the airflow in the air duct 270 flows upward to the center of the guide protrusion 212, it can flow outwards under its guiding effect and be blown outwards through the annular top air outlet 280, thereby improving the smoothness of airflow turning and distribution and reducing disturbances and noise caused by sharp airflow turning.

[0048] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
