Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to an indoor unit of a vertical air conditioner. Background Technology

[0002] With social development and the continuous improvement of people's living standards, various air conditioning devices have become an indispensable electrical appliance in people's daily lives. These devices help people reach a comfortable temperature when the ambient temperature is too high or too low. Currently, air conditioning devices mainly include various types of air conditioners and fans.

[0003] Air conditioners can be categorized into floor-standing, wall-mounted, and ceiling-mounted types based on the installation method of their indoor units. Floor-standing air conditioner indoor units are mainly used in larger public places such as living rooms, schools, and hospitals. Wall-mounted and ceiling-mounted air conditioner indoor units are primarily used in smaller indoor environments, such as bedrooms. Because floor-standing air conditioner indoor units generally have a larger air volume and are used in a wider range of scenarios, their application is becoming increasingly widespread.

[0004] Currently, most high-end floor-standing air conditioner indoor units adopt a dual-outlet airflow design. In this design, the existing guide vanes typically open by rotating, opening backward, or opening inward. For example, many existing guide vanes use a robotic arm structure that opens by rotation. While these current guide vane opening methods generally achieve dual-outlet opening, they result in overly complex dividing lines on the dual guide vanes, hindering a simplified design approach. The fragmented divisions reduce the overall aesthetic appeal of this type of floor-standing air conditioner indoor unit, negatively impacting the user experience. Utility Model Content

[0031] This embodiment provides a vertical air conditioner indoor unit with two side guide plates that overlap and open towards the middle. This simplifies the division of the guide plates while showcasing dual air outlets, effectively improving the user experience.

Figure 7 This is a partial structural schematic diagram of the indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention. Figure 8 yes Figure 7 Enlarged diagram of region C in the middle. Figure 9This is a partial rear view of the indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention, with the double guide plates closed. Figure 10 This is a partial rear view of the structure of the indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention when the double guide plates are opened.

[0032] like Figures 1 to 10 As shown, the indoor unit 100 of the vertical air conditioner in this embodiment generally includes: a housing 110, a first guide plate 210, a second guide plate 220, a first transmission structure, and a second transmission structure. The housing 110 has a first air outlet 111 and a second air outlet 112 arranged side-by-side at its front. The first guide plate 210 is configured to slidably open and close the first air outlet 111. The second guide plate 220 is configured to slidably open and close the second air outlet 112. The first transmission structure is connected to the first guide plate 210 and configured to drive the first guide plate 210 to move horizontally to the right when the first air outlet 111 is opened. The second transmission structure is connected to the second guide plate 220 and configured to drive the second guide plate 220 to move to the left and rear when the second air outlet 112 is opened.

[0033] like Figure 4 , Figure 5 , Figure 6 and Figure 10 As shown, the indoor unit 100 of the vertical air conditioner in this embodiment divides the guide plate into two parts and achieves sliding overlap opening of the double guide plates. This reduces the phenomenon of overly fragmented guide plates in dual-outlet cabinet air conditioners, greatly simplifies the shape of the front guide plate of the cabinet air conditioner, and vividly displays the dual air outlets. It should be noted that the indoor unit 100 of the vertical air conditioner is a cabinet air conditioner, the first guide plate 210 and the second guide plate 220 are referred to as the double guide plates, the first air outlet 111 and the second air outlet 112 are referred to as the double air outlets, and opening the double guide plates means that the double guide plates open the double air outlets.

[0034] In one specific embodiment, both the first air outlet 111 and the second air outlet 112 have a first width. Both the first guide plate 210 and the second guide plate 220 have a second width, which is greater than or equal to the first width. The width of the first guide plate 210 is greater than or equal to the first air outlet 111, and the width of the second guide plate 220 is greater than or equal to the second air outlet 112, ensuring that the two guide plates can completely close the two air outlets, preventing dust from entering from the two air outlets. The fact that both the first guide plate 210 and the second guide plate 220 have the second width ensures that the two guide plates completely overlap when opened.

[0035] Furthermore, in a preferred embodiment, the second width of the first guide plate 210 and the second guide plate 220 is greater than or equal to the first width of the first air outlet 111 and the second air outlet 112. For example... Figure 7 and Figure 8As shown, a middle section 117 is provided between the first air outlet 111 and the second air outlet 112. The second width of the first guide plate 210 and the second guide plate 220 is greater than the first width of the first air outlet 111 and the second air outlet 112. This allows the middle section 117 to be completely covered when the first guide plate 210 and the second guide plate 220 are completely closed, with the right side of the first guide plate 210 extending beyond the first air outlet 111 and the left side of the second guide plate 220 extending beyond the second air outlet 112. This results in the upper half of the indoor unit 100 of the vertical air conditioner having only two guide plates on the front, thus fully realizing the simplified design of the indoor unit 100 of the vertical air conditioner.

[0036] In one specific embodiment, such as Figures 1 to 6 As shown, the first air outlet 111 and the second air outlet 112 have an inclined surface 113 that gradually slopes forward from bottom to top. Furthermore, a first sliding groove 410 and a second sliding groove 420 are formed on the inclined surface 113, with the first sliding groove 410 positioned above the second sliding groove 420. The first sliding groove 410 is horizontally positioned, while the second sliding groove 420 gradually decreases in elevation from right to left. Since the first sliding groove 410 and the second sliding groove 420 are located on the inclined surface 113, the fact that the first sliding groove 410 is positioned above the second sliding groove 420 naturally means that the first sliding groove 410 is further forward than the second sliding groove 420.

[0037] In one specific embodiment, the first transmission mechanism includes a first drive structure (not shown in the figure) and a first connecting rod 310. The first connecting rod 310 is connected to both the first drive mechanism and the first guide plate 210. When the first drive mechanism drives the first connecting rod 310 to move within the first slide groove 410, the first connecting rod 310 drives the first guide plate 210 to move. When the first air outlet 111 is opened, since the first slide groove 410 is horizontally positioned, the first connecting rod 310 moves horizontally to the right within the first slide groove 410, thereby driving the first guide plate 210 to move horizontally to the right.

[0038] The second transmission mechanism includes a second drive structure (not shown in the figure) and a second connecting rod 320. The second connecting rod 320 is connected to both the second drive mechanism and the second guide plate 220. When the second air outlet 112 is opened, because the second slide rail 420 gradually decreases from right to left, and as mentioned earlier, the first slide rail 410 is further forward than the second slide rail 420, the second connecting rod 320 moves to the left and rearward within the second slide rail 420, thereby causing the second guide plate 220 to move to the left and rearward. "Rearward" means that the second guide plate 220 moves behind the first guide plate 210, thus achieving overlapping opening of the two guide plates.

[0039] Specifically, both the first and second drive structures can be motors. The direction of rotation of the motors can adjust the movement direction of the first connecting rod 310 and the second connecting rod 320, thereby adjusting the movement direction of the first guide plate 210 and the second guide plate 220, and realizing the opening and closing of the first air outlet 111 and the second air outlet 112. Furthermore, the type of motor needs to be suitable for use in the indoor unit 100 of a vertical air conditioner, for example, suitable for installation inside the inclined plane 113. In addition to connecting to and driving the movement of the first connecting rod 310, the first drive structure can also be fixedly connected to the inside of the housing 110. Similarly, in addition to connecting to and driving the movement of the second connecting rod 320, the second drive structure can also be fixedly connected to the inside of the housing 110.

[0040] In a preferred embodiment, such as Figure 3 , Figure 6 , Figure 9 and Figure 10 As shown, the front end of the first connecting rod 310 is connected to the upper rear side of the first guide plate 210. The front end of the second connecting rod 320 is connected to the upper rear side of the second guide plate 220. The first connecting rod 310 and the second connecting rod 320 are respectively located on the rear side of the first guide plate 210 and the second guide plate 220, which can ensure the overall visual uniformity of the front of the indoor unit 100 of the vertical air conditioner.

[0041] Furthermore, the length of the front end of the first connecting rod 310 is greater than the length of the front end of the second connecting rod 320, which is for the stability considerations of opening and closing the dual air outlets with double guide plates. Since the first connecting rod 310 is located on the upper rear side of the first guide plate 210, it is particularly important to ensure that the second guide plate 220 moves towards the rear of the first guide plate 210 when the double guide plates are opened, so as not to interfere with the first connecting rod 310. Therefore, the gradual downward setting of the second slide 420 from right to left is crucial, so that the upper end of the first guide plate 210 is lower than the first connecting rod 310. This also ensures that when the double guide plates are opened, the first guide plate 210 and the second guide plate 220 fit close together without a large gap in between, improving the overlapping opening effect.

[0042] Figure 7 The partial structure of the indoor unit 100 of the vertical air conditioner actually refers to the structure excluding the double guide plates. In a specific embodiment, such as Figure 7 and Figure 8 As shown, a forward-extending plane 114 is located below the first air outlet 111 and the second air outlet 112. A slot 115 is provided on the plane 114. When the first guide plate 210 and the second guide plate 220 open and close the first air outlet 111 and the second air outlet 112, the lower ends of the first guide plate 210 and the second guide plate 220 slide within the slot 115. The slot 115 effectively ensures the smooth sliding of the upper transmission structure and ensures the smooth movement of the double guide plates during operation without deviation.

[0043] More specifically, when the first guide plate 210 opens the first air outlet 111, the lower end of the first guide plate 210 slides horizontally to the right within the first area 510 of the slot 115. When the second guide plate 220 opens the second air outlet 112, the lower end of the second guide plate 220 slides to the left and rear within the second area 520 of the slot 115. It should be noted that the slot 115 is designed to allow for a backward movement so that the second guide plate 220 can slide to the left and rear when changing from a closed state to an open state. In fact, the slot 115 on the lower plane 114 is matched with the sliding groove on the upper inclined plane 113, which effectively ensures the smooth sliding process of the two guide plates.

[0044] In a preferred embodiment, the first region 510 of the card slot 115 has a uniform depth. The depth of the second region 520 of the card slot 115 gradually increases from right to left. The upper and lower ends of the first guide plate 210 are both horizontal, and the left and right ends have the same height. The upper end of the second guide plate 220 is horizontal, the lower end is beveled, and the height of the left end is greater than the height of the right end. The gradually decreasing height of the lower end of the second guide plate 220 from right to left matches the gradually increasing depth of the second region 520 from right to left.

[0045] In this design, the first region 510 of the slot 115 has a uniform depth, and the upper and lower ends of the first guide plate 210 are horizontal, while the left and right ends have the same height. This ensures that the upper end of the first guide plate 210 remains horizontal and its overall height remains constant during horizontal movement. The depth of the second region 520 of the slot 115 gradually increases from right to left. With the upper end of the second guide plate 220 horizontal, the lower end sloping, and the left end higher than the right, and with the lower end of the second guide plate 220 gradually decreasing in height from right to left to match the gradually increasing depth of the second region 520 from right to left, it is guaranteed that the upper end of the second guide plate 220 remains horizontal throughout its movement.

[0046] Furthermore, as the second guide plate 220 opens the second air outlet 112 and moves to the left and rear, its overall height decreases, thus ensuring that the second guide plate 220 is lower than the first connecting rod 310. This is also an important aspect of the matching arrangement between the lower slot 115 and the upper slide groove, preventing interference between the second guide plate 220 and the first connecting rod 310 and ensuring smooth sliding of the double guide plates. The vertical air conditioner indoor unit 100 of this embodiment, through its unique structural design, not only reduces segmentation by opening the double guide plates through sliding overlap, but also effectively solves the interference problem of the transmission mechanism after overlap.

[0047] like Figure 9As shown, when the first guide plate 210 and the second guide plate 220 are closed to the first air outlet 111 and the second air outlet 112, the upper ends of the first guide plate 210 and the second guide plate 220 are flush, improving the front visual effect of the indoor unit 100 of the vertical air conditioner. Figure 10 As shown, when the first air outlet 111 and the second air outlet 112 are opened by the first guide plate 210 and the second guide plate 220, the upper end of the second guide plate 220 is lower than the first guide plate 210 and the first connecting rod 310 to avoid interference. Furthermore, only the first guide plate 210 can be seen from the front of the vertical air conditioner indoor unit 100, while the second guide plate 220, the first connecting rod 310, and the second connecting rod 320 are completely obscured, further ensuring the frontal visual effect of the vertical air conditioner indoor unit 100.

[0048] It should be noted that this embodiment uses a connecting rod structure at the top to drive the movement of the double guide plates, and a slot 115 at the bottom to allow the lower ends of the double guide plates to slide. In some other embodiments, the upper and lower positions can be interchanged. For example, a slot 115 can be set at the top to allow the upper ends of the double guide plates to slide within the slot 115, and a connecting rod structure at the bottom can drive the movement of the double guide plates. This can be configured according to the specific situation of the indoor unit 100 of the vertical air conditioner. Furthermore, it should be emphasized that in this embodiment, the double guide plates open and close the double air outlets synchronously, that is, the first driving structure and the second driving structure open and close synchronously, and operate at the same speed. Otherwise, when the first guide plate 210 moves horizontally to the right, it will be blocked by the second guide plate 220.

[0049] In one specific embodiment, the interior of the housing 110 may define a cavity, and an air inlet 116 may also be provided on the housing 110. Specifically, the air inlet 116 may be located on the rear side of the housing 110. Furthermore, a filter may be provided at the air inlet 116 to filter dust and impurities in the air entering the cavity through the air inlet 116. Both the first air outlet 111 and the second air outlet 112 may be provided with vanes to change the direction of the airflow from the first air outlet 111 and the second air outlet 112. For example, horizontal vanes may be provided to adjust vertical airflow; vertical vanes may be provided to adjust horizontal airflow.

[0050] Specifically, the housing 110 may include a front panel, a rear panel, two side panels, a top panel, and a bottom panel. The air inlet 116 may be located on the rear panel, and the first air outlet 111 and the second air outlet 112 may be located on the front panel. The top and bottom panels not only make the indoor unit 100 of the vertical air conditioner more integrated and aesthetically pleasing, but also improve the stability of the indoor unit 100 of the vertical air conditioner to a certain extent.

[0051] In one specific embodiment, the indoor unit 100 of the vertical air conditioner may further include a heat exchanger (not shown in the figure), disposed in the cavity and configured to exchange heat with the air entering the cavity. It should be noted that the indoor unit 100 of the vertical air conditioner produces condensate during cooling. Specifically, during the cooling process, the refrigerant absorbs heat from the room and releases it to the outside through compression and expansion, thereby cooling the indoor environment. During this process, the refrigerant becomes a low-temperature, low-pressure state, at which point it absorbs heat from the room through the heat exchanger, which acts as an evaporator, and also absorbs water vapor from the air. After absorbing the heat and water vapor from the room, the refrigerant becomes a high-temperature, high-pressure state, and then releases this heat and water vapor to the outside through the condenser. During this process, due to the temperature difference inside the indoor unit 100, water vapor condenses into water droplets between the heat exchanger and the condenser, thus forming condensate.

[0052] Therefore, in one specific embodiment, the indoor unit 100 of the vertical air conditioner may further include a drip tray (not shown in the figure), which can be installed at the heat exchanger and configured to collect and receive condensate. Providing a drip tray is essential to prevent dripping problems in the indoor unit 100 and to ensure the reliable operation of the heat exchanger. Furthermore, the indoor unit 100 may also include a drain pipe (not shown in the figure), configured to discharge the condensate from the drip tray to the outside of the indoor unit 100, thus preventing the condensate from affecting the indoor environment.

[0053] The heat exchanger can be installed inside the cavity near the air inlet 116, and its shape can be matched with the air inlet 116, so that the air entering the cavity through the air inlet 116 can be completely heated by the heat exchanger, improving heat exchange efficiency. After entering the cavity through the air inlet 116 and being heated by the heat exchanger, the air is sent to the indoor environment through the first air outlet 111 and the second air outlet 112.

[0054] When the indoor unit 100 of the vertical air conditioner is operating in cooling mode, the air that has been heated by the heat exchanger is cold air. After being delivered to the indoor environment through the air outlet 111, it can lower the indoor temperature and make the user feel cool. When the indoor unit 100 of the vertical air conditioner is operating in heating mode, the air that has been heated by the heat exchanger is hot air. After being delivered to the indoor environment through the air outlet 111, it can raise the indoor temperature and make the user feel warm.

[0055] In addition, a blower fan (not shown in the figure) can be installed in the cavity inside the casing 110 of the indoor unit 100 of the vertical air conditioner. Located in front of the heat exchanger, the blower fan can deliver the air after heat exchange through the heat exchanger to the indoor environment through the first air outlet 111 and the second air outlet 112. The fan of the indoor unit 100 of the vertical air conditioner can mainly include three types: centrifugal, cross-flow, and axial flow. Among them, the air in the centrifugal fan is subjected to centrifugal force, creating a vacuum in the center of the impeller. The air drawn in is turned 90° at the impeller inlet and enters the flow channel formed by the blades, gaining kinetic and pressure energy under the action of the blades. The airflow thrown out from the blade channel enters the volute, and after being concentrated and guided, it is discharged from the outlet of the centrifugal fan.

[0056] A cross-flow fan, also known as a cross-flow fan, allows airflow to enter radially from the open end of the impeller, pass through the interior of the impeller, and exit into the volute from the other side of the impeller, forming the working airflow. In an axial flow fan, the airflow flows axially within the impeller. Each of these three types of fans has its advantages and disadvantages, and the appropriate configuration can be chosen based on the specific circumstances. Regardless of the type of fan, all can deliver the air heated by the heat exchanger to the indoor environment through the first air outlet 111 and the second air outlet 112 to regulate the indoor temperature.

[0057] The air supply fan can also be equipped with a fan motor to drive its rotation. The airflow speed of the indoor unit 100 of the vertical air conditioner can be adjusted by regulating the speed of the fan motor driving the air supply fan. In a preferred embodiment, the air supply fan can be a cross-flow fan. This is because the axial length of a cross-flow fan is not limited, and the impeller length can be arbitrarily selected according to different usage needs. Furthermore, the airflow passes through the impeller and is acted upon by the blades twice, thus allowing the airflow to reach a long distance, resulting in longer air delivery. In addition, cross-flow fans have no turbulence, provide uniform airflow, and have lower noise, effectively improving the user experience.

This provides a vertical air conditioner indoor unit 100 with guide plates on both sides overlapping and opening towards the middle, which simplifies the division of the guide plates while showcasing dual air outlets.

[0059] Furthermore, in this embodiment, the indoor unit 100 of the vertical air conditioner has an inclined surface 113 that gradually slopes forward from bottom to top above the first air outlet 111 and the second air outlet 112. A first sliding groove 410 and a second sliding groove 420 are provided on the inclined surface 113, wherein the first sliding groove 410 is positioned above the second sliding groove 420, the first sliding groove 410 is horizontally positioned, and the second sliding groove 420 gradually decreases from right to left. When the first guide plate 210 opens the first air outlet 111, the lower end of the first guide plate 210 is in the slot 11. Within the first region 510 of the 5, the 5 slides horizontally to the right. When the second guide plate 220 opens the second air outlet 112, the lower end of the second guide plate 220 slides to the left and rear within the second region 520 of the slot 115. The depth of the first region 510 of the slot 115 is the same, and the depth of the second region 520 of the slot 115 gradually increases from right to left. Through the unique design of each part of the structure, the space reservation problem of the internal structure after the double guide plates overlap can be effectively solved, ensuring that the double guide plates slide smoothly and improving the user experience.
