Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an air conditioner water diversion mechanism and an air conditioner. Background Art

[0002] Wall-mounted air conditioners are generally hung on the wall through a wall-mounted horizontal plate, and the wall-mounted horizontal plate is connected to the back side of the base through a wall-mounted vertical plate connected to the base. Limited by the size of the indoor unit of the air conditioner, it is usually set that the parts of the wall-mounted vertical plate except the upper and lower ends are as close to the base as possible, for example, the gap between the two is less than 7 mm. However, when the condensed water generated on the back of the base flows downward and passes through the gap between the wall-mounted vertical plate and the base, it will contact and adhere to the wall-mounted vertical plate due to the small gap, thereby causing dripping water and affecting the user experience. Summary of the Utility Model

Detailed Embodiments

[0026] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0027] The following will be combined with Figures 1 - 4 describe the air conditioner water diversion structure and the air conditioner according to an embodiment of the present utility model.

[0028] The air conditioner water diversion structure of the embodiment of the present utility model includes a base 1. The base 1 includes a rear wall 11, a first water diversion rib 12 and a water diversion mechanism. The rear wall 11 extends in a first direction. A wall-mounted vertical plate 2 is connected to the back side of the rear wall 11. The extending direction of the wall-mounted vertical plate 2 is perpendicular to the first direction. An isolation cavity 112 is defined between the wall-mounted vertical plate 2 and the rear wall 11. The first water diversion rib 12 is arranged on the back of the rear wall 11. The extending direction of the first water diversion rib 12 forms an acute angle with the first direction. Part of the first water diversion rib 12 is located in the isolation cavity 112, and the part where the lower end of the first water diversion rib 12 is located is outside the isolation cavity 112. The water diversion mechanism is connected to the lower end of the first water diversion rib 12 and is used to guide the condensed water on the first water diversion rib 12 into the water receiving tray 4.

[0029] For the air conditioner water diversion mechanism according to the embodiment of the present utility model, a first water diversion rib 12 with an extending direction forming an acute angle with the first direction is arranged on the back of the rear wall 11. Part of the first water diversion rib 12 is located in the isolation cavity 112 formed between the wall-mounted vertical plate 2 and the rear wall 11, and the part where the lower end of the first water diversion rib 12 is located is outside the isolation cavity 112. Thus, when the condensed water located in the isolation cavity 112 flows downward along the rear wall 11 under the action of gravity, it will be blocked by the first water diversion rib 12 and flow out of the isolation cavity 112 under the guidance of the first water diversion rib 12. Therefore, it effectively avoids the continuous downward flow of condensed water in the isolation cavity 112. At this time, the width of the part of the isolation cavity 112 below the first water diversion rib 12 can be designed to be smaller to meet the size requirements, and it avoids the condensed water contacting the wall-mounted vertical plate 2 and causing dripping, improving the user experience.

[0030] It should be noted that the first water diversion rib 12 is arranged at a position adjacent to the upper end of the rear wall 11. The width of the part of the isolation cavity 112 above the first water diversion rib 12 needs to be greater than 7 mm to avoid the condensed water in this part adhering to the wall-mounted vertical plate 2. As Figure 1 shown, the first direction is the left-right direction of the air conditioner, and the second direction is the up-down direction of the air conditioner.

[0031] In some embodiments, as Figure 1 and Figure 3 shown, the part where the upper end of the first water diversion rib 12 is located is outside the isolation cavity 112.

[0032] Thus, the first water diversion rib 12 straddles the wall-mounted vertical plate 2. When the condensed water in the part of the isolation cavity 112 above the first water diversion rib 12 flows downward along the rear wall 11, it will basically be completely blocked by the first water diversion rib 12. The probability of the condensed water entering the part of the isolation cavity 112 below the first water diversion rib 12 is lower, and thus the probability of causing dripping is lower, and the user experience is higher.

[0033] Specifically, on the projection plane perpendicular to the height direction, the dimension of the projection of the first water diversion rib 12 in the first direction is greater than the width of the wall-mounted vertical plate 2.

[0034] It should be noted that the upper end of the first water guiding rib 12 can also be connected to another water guiding rib parallel or angled to the first direction, and the free end of this water guiding rib and the lower end of the first water guiding rib 12 are respectively located on opposite sides of the isolation cavity 112 in the first direction.

[0035] In some embodiments, the angle between the extending direction of the first water guiding rib 12 and the first direction is α, where 10° ≤ α ≤ 45°.

[0036] At this angle, the first water guiding rib 12 can guide the condensed water while avoiding the condensed water on it from accumulating and overflowing into the lower isolation cavity 112 due to too small an α angle, thus causing dripping, and also avoiding the condensed water on it from sliding too fast due to too large an α angle, resulting in water droplet splashing.

[0037] Specifically, the angle between the extending direction of the first water guiding rib 12 and the first direction can be 10°, 30°, and 45°.

[0038] In some embodiments, the top surface of the first water guiding rib 12 is connected to the back surface of the rear wall 11 and forms a water guiding groove with an upward opening around it, and the extending direction of the water guiding groove is the same as the extending direction of the first water guiding rib 12.

[0039] Thus, after the condensed water is blocked by the first water guiding rib 12, it drips into the water guiding groove, and the water guiding groove has a better guiding effect on the condensed water, effectively avoiding the condensed water from overflowing the first water guiding rib 12 along the thickness direction of the rear wall 11 and causing dripping.

[0040] Specifically, the water guiding groove is generally a V-shaped groove, and the angle between the top surface of the first water guiding rib 12 and the back surface of the rear wall 11 can be 40°, 50°, 60°, and 80°.

[0041] In some embodiments, as Figure 1 and Figure 3 shown, a water receiving plate 17 is provided on the back surface of the rear wall 11. The top surface of the water receiving plate 17 is connected to the back surface of the rear wall 11 and forms a water receiving groove 171 with an upward opening around it. The rear wall 11 is provided with a through hole 111 communicating the water receiving groove 171 and the water receiving tray 4. The water receiving groove 171 is located below the first water guiding rib 12 and is adapted to receive the condensed water from the first water guiding rib 12.

[0042] The water receiving groove 171 formed by the water receiving plate 17 and the rear wall 11 extends along the left direction to the left and right ends of the rear wall 11, and the water receiving groove 171 is used to receive all the condensed water on the back surface of the rear wall 11. At this time, by setting the condensed water on the first water guiding rib 12 to also flow into the water receiving groove 171 and flowing to the water receiving tray 4 through the through hole 111, there is no need to additionally provide a structure for guiding this part of the condensed water to the water receiving tray 4, and the structure of the base 1 is simple and the manufacturing cost is low.

[0043] Specifically, the water receiving plate 17 is a V-shaped plate structure with an opening facing downward, that is, the height of the water receiving plate 17 at the central position in the left-right direction is higher than the heights at both ends, and there are two through holes 111 which are respectively located at both ends of the water receiving plate 17.

[0044] In some embodiments, such as Figure 1 and Figure 3 shown, the water guiding mechanism includes a second water guiding rib 13. The second water guiding rib 13 is arranged on the back surface of the rear wall 11. The extending direction of the second water guiding rib 13 forms an angle with the first direction. The upper end of the second water guiding rib 13 is connected to the lower end of the first water guiding rib 12. The second water guiding rib 13 is located outside the isolation cavity 112 and above the water receiving plate 17.

[0045] The second water guiding rib 13 located outside the isolation cavity 112 is used to receive and guide the condensed water from the first water guiding rib 12, thereby preventing the condensed water flowing out of the isolation cavity 112 from re-entering the isolation cavity 112. At this time, the width of the part of the isolation cavity 112 at the same height as the second water guiding rib 13 can be designed to be smaller, such as less than 7 mm, to meet the requirements of the air conditioner size design.

[0046] Specifically, the second water guiding rib 13 extends in the up-down direction.

[0047] In some embodiments, such as Figure 3 shown, there are two wall-mounted vertical plates 2, two first water guiding ribs 12 and two second water guiding ribs 13, which correspond one by one. The two first water guiding ribs 12 are arranged at intervals in the first direction, and the two second water guiding ribs 13 are arranged at intervals in the first direction. The water guiding mechanism further includes a third water guiding rib 14. The extending direction of the third water guiding rib 14 forms an acute angle with the first direction. The lower ends of the two second water guiding ribs 13 are connected to the third water guiding rib 14. The third water guiding rib 14 is located above the water receiving plate 17.

[0048] At this time, only one third water guiding rib 14 is needed to receive and guide the condensed water from the two second water guiding ribs 13, so that the condensed water can finally enter the water receiving groove 171 and enter the water receiving tray 4 through the through hole 111, thereby making the structure of the base 1 simpler and the cost lower. At the same time, by setting the extending direction of the third water guiding rib 14 to form an acute angle with the first direction, it is more convenient for the condensed water on the third water guiding rib 14 to flow in the set direction and enter the water receiving tray 4 more reliably.

[0049] Specifically, the two ends of the third water guiding rib 14 in the left-right direction are respectively adjacent to the two ends of the rear wall 11 in the left-right direction. The lower ends of the two second water guiding ribs 13 are connected to the top surface of the third water guiding rib 14. In addition, the third water guiding rib 14 can also be inclined obliquely upward to better restrict the condensed water to flow in the front-rear direction.

[0050] It should be noted that a wall-mounted cross plate 3 is connected between two wall-mounted vertical plates 2, and the air conditioner indoor unit is mounted on the wall through the wall-mounted cross plate 3.

[0051] In some embodiments, as Figure 2 shown, the water diversion mechanism further includes a fourth water diversion rib 15. The fourth water diversion rib 15 extends along a second direction, the second direction is perpendicular to the first direction, the lower end of the fourth water diversion rib 15 is connected to the water receiving plate 17, and the lower end of the third water diversion rib 14 is connected to the fourth water diversion rib 15.

[0052] The fourth water diversion rib 15 can receive and guide the condensed water from the third water diversion rib 14 to directly guide the condensed water into the water receiving tank 171, avoiding the condensed water on the third water diversion rib 14 from dripping in the air and causing water droplets to splash in the water receiving tank 171.

[0053] Specifically, the upper end of the fourth water diversion rib 15 extends to the upper end of the rear wall 11, and the fourth water diversion rib 15 is also used to guide the condensed water from other positions on the back surface of the rear wall 11.

[0054] Alternatively, the lower end of the third water diversion rib 14 is connected to the water receiving plate 17. That is, the third water diversion rib 14 directly guides the condensed water into the water receiving tank 171, so that the structure of the base 1 is simpler and the cost is lower.

[0055] In some embodiments, as Figure 1 and Figure 3 shown, the base 1 further includes a fifth water diversion rib 16. The fifth water diversion rib 16 extends along a second direction, the second direction is perpendicular to the first direction, the upper end of the first water diversion rib 12 is connected to the fifth water diversion rib 16, and the lower end of the fifth water diversion rib 16 is connected to the third water diversion rib 14.

[0056] The condensed water in the fifth water diversion rib 16 above the first water diversion rib 12 can continue to flow downward along the extension direction of the fifth water diversion rib 16 to reach the third water diversion rib 14, effectively avoiding the risk that too much condensed water is guided by the first water diversion rib 12 through the isolation cavity 112 and increasing the risk of condensed water dripping into the isolation cavity 112.
