Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to an air conditioner. Background Technology

[0002] When an air conditioner is cooling in summer, condensation forms on the plastic components inside the indoor unit due to contact with both hot and cold air. As the cooling time increases, a large amount of condensation forms on the surface of the plastic components in contact with the hot air, creating water droplets. At this point, because their own weight exceeds their surface tension, the water droplets drip off. In practice, to prevent condensation from spreading, drain channels are installed on the plastic components to drain the condensation, with a drip tray at the end of the drain channel for water routing and collection. However, due to the structural distribution of air conditioners, in some models, there is a certain height difference between the end of the drain channel and the drip tray, resulting in a "drip, drip" sound from inside the indoor unit. This sound can disturb and affect the user's rest. Utility Model Content

[0003] To overcome the technical problem of noise caused by condensation dripping due to a certain height difference between the end of the plastic-molded drain channel and the water tray in some existing air conditioners, this utility model provides an air conditioner.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An air conditioner includes a molded part with a drain channel for draining condensate. A water collection tray is provided below the end of the drain channel. A guide structure is provided at the end of the drain channel, extending from the end of the drain channel to the water collection tray for guiding the condensate. The horizontal projection of the molded part and the drain channel covers the horizontal projection of the guide structure.

[0006] In this application, a guide structure is added to the end of the drainage channel to avoid noise caused by condensation dripping; the horizontal projection of the plastic part and the drainage channel covers the horizontal projection of the guide structure, that is, the guide structure extends vertically downward or backward to avoid interference with other parts during assembly and use.

[0007] In some embodiments, the guide structure is a guide groove, the width of which is greater than or equal to the width of the outlet at the end of the drainage channel, and the angle between the extension direction of the guide groove and the vertical line is less than or equal to 15°.

[0008] In some embodiments, the guide channel is further provided with steps for the condensate to flow down the steps.

[0009] In some embodiments, the distance between both ends of the guide groove in the width direction and both ends of the drainage channel outlet is greater than 1 mm.

[0010] In some embodiments, the guide structure consists of several strip ribs, and the angle between the extension direction of the strip ribs and the vertical line is less than or equal to 15°.

[0011] In some embodiments, the strip connection extends to the side wall of the air conditioner, and the strip is provided with reinforcing ribs.

[0012] In some embodiments, the guide structure has a curved surface as a guide surface, and the angle between the tangent direction and the vertical line at any point on the guide surface is less than or equal to 15°.

[0013] In some embodiments, a hydrophilic layer is provided on the surface of the guiding structure used to guide condensation.

[0014] In some embodiments, the vertical distance between the lowest point of the guide structure and the inner surface of the water-receiving tray cavity is 6mm-12mm.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] like Figures 1-7 As shown, this utility model provides an air conditioner.

[0029] An air conditioner includes a plastic molded part, on which a drain channel 1 for draining condensate is provided, and a water collection tray 4 is provided below the end 2 of the drain channel.

[0030] Reference Figure 1 As shown, the improvement of this utility model compared with the prior art is that a guide structure is provided at the end 2 of the drainage channel. The guide structure extends from the end 2 of the drainage channel to the water receiving tray 4 for guiding condensate.

[0031] A guide structure is added to the end 2 of the drainage channel to prevent condensation from dripping and causing noise.

[0032] The horizontal projection of the molded part and the drainage channel 1 covers the horizontal projection of the guide structure, that is, the guide structure extends vertically downward or backward to avoid interference with other parts during assembly and use.

[0033] The implementation of the guidance structure includes different methods, firstly based on... Figures 1-4 This utility model discloses a method of using strip ribs 31 as a guide structure.

[0034] In this embodiment, the guide structure is a single strip rib 31. In other embodiments, there may be multiple strip ribs. The angle between the extension direction of the strip rib 31 and the vertical line is 5°.

[0035] In this embodiment, to facilitate assembly and implementation and avoid interference, it is preferable that the angle between the extension direction of the strip rib 31 and the vertical line be less than or equal to 15°, so as to prevent condensation from dripping under gravity, which would make it difficult for the guide structure to achieve its guiding purpose. Obviously, multiple strip ribs 31 can be configured.

[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the strip rib 31 extends to the side wall 7 of the air conditioner, and the strip rib 31 is provided with reinforcing ribs 6 to ensure structural strength.

[0037] Reference Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a plurality of transverse ribs 5 are provided in the area near the end of the drainage channel 1. The plurality of transverse ribs 5 are staggered and connected to the two ends of the width direction of the drainage channel 1 respectively, and the horizontal projections of the adjacent transverse ribs 5 overlap.

[0038] By adding transverse ribs 5, the flow velocity of condensed water in drainage channel 1 is reduced, and the flow velocity of condensed water at the end of drainage channel 2 is prevented from being too fast and thus unable to flow down along the guide structure due to inertia.

[0039] Reference Figure 5 As shown, in some embodiments, the guiding structure is a guide groove 32, the width of the guide groove 32 is greater than or equal to the width of the outlet of the end of the drainage channel 2, and the angle between the extension direction of the guide groove 32 and the vertical line is less than or equal to 15°.

[0040] In this embodiment, the distance between the two ends of the guide groove 32 in the width direction and the two ends of the outlet of the drainage channel 2 is 1mm. In practice, it is preferred to be greater than or equal to 1mm, so as to ensure that the entire outlet of the drainage channel 2 is covered and the guiding function is perfectly realized.

[0041] Reference Figure 6 and Figure 7 As shown, in some embodiments, the guide channel 32 is further provided with a step 33 for the condensate to flow downwards along the step 33. By adding the step 33, the flow rate of the condensate is further reduced, thereby further reducing the possibility of noise generation.

[0042] In some other embodiments, the guide structure has a curved surface as a flow guide surface, and the angle between the tangent direction and the vertical line at any point on the flow guide surface is less than or equal to 15°.

[0043] In this embodiment, a hydrophilic layer is provided on the surface of the guiding structure used to guide the condensation, and the hydrophilic layer material can be silicone or polyurethane, etc.

[0044] Preferably, the vertical distance between the lowest point of the guide structure and the inner surface 8 of the water receiving tray 4 is 6mm-12mm.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
