DETAILED DESCRIPTION

[0047] It should be noted that, in the absence of conflict, the features of the present invention can be combined with each other.

[0048] In addition, the directional indications mentioned in the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly. For example, the front, back, left, and right mentioned in the present invention refer to the base of the present invention in a certain position. Figure 5 In the directions shown in the figure, the inside and outside mentioned in the present invention refer to the direction close to the center of the base as the inside and the direction away from the center of the base as the outside.

[0049] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0050] See also Figure 1-7 As shown, the present invention provides an anti-blocking structure, comprising:

[0051] a drain port 31, suitable for draining water; and

[0052] at least one water outlet 32 ​​adapted to direct water to the drain 31;

[0053] The outlet 32 ​​has a limited diameter opening, and the size of objects allowed to pass through the limited diameter opening is smaller than the size of objects allowed to pass through any other part of the outlet 32 ​​. The maximum size of objects allowed to pass through the limited diameter opening is smaller than the diameter of the drain port 31 .

[0054] The present invention also provides a base, including an upper base 4 and a lower base 3 that are detachably connected, an anti-blocking structure is provided on the lower base 3, a rear water channel is provided on the rear side of the lower base 3, the rear water channel is used to receive condensed water on the back of the upper base 4, and the rear water channel is located at the top of the water outlet 32 ​​along the gravity direction. The anti-blocking structure is arranged on the left and / or right side of the lower base 3, and the anti-blocking structure includes at least one water outlet 32, and the water outlet 32 ​​is connected to the rear water channel. The water outlet 32 ​​has an inner wall 321 and an outer wall 322, and a protrusion 37 that is close to the outer wall 322 is provided at the front of the water outlet 32, and the protrusion 37 has a first side wall 371, a second side wall, and a circumferential side wall 372 located between the first side wall 371 and the second side wall, and the second side wall is arranged close to the outer wall 322, and the first side wall 371 and the circumferential side wall 372 are smoothly connected, and the smooth arrangement is conducive to preventing the water flow from impacting the protrusion 37 when the water volume is large, thereby increasing the turbulence. Figure 4 As shown, the vertical distance between the plane where the first side wall 371 is located and the plane where the inner side wall 321 is located is the size of the diameter-limiting opening. The bottom of the protrusion 37 is provided with a notch 373 that passes through the first side wall and the second side wall 371 in the left and right directions. The notch 373 and the bottom wall of the waterway of the water outlet 32 ​​define a drain port 31, and the condensed water in the water outlet 32 ​​is discharged from the base through the drain port 31. The setting of the protrusion 37 makes the path for the condensed water to enter the drain hose through the drain port 31 longer. At this time, the drain port has a certain flow stabilization effect. On the one hand, it avoids the increase of water flow turbulence caused by the impact of condensed water, and on the other hand, it also has a certain noise reduction function. The front side of the lower base 3 is also provided with a front waterway 34, which is connected to the drain port 31. The condensed water in the front waterway 34 is discharged from the base through the drain port 31.

[0055] The present invention sets the size of the limited diameter opening to be smaller than the diameter of the drain port 31. When the condensed water flows to the drain port 31 through the water outlet 32, the larger dirt mixed in the condensed water is stuck in the limited diameter opening, while the condensed water can still flow over the dirt and continue to flow into the drain port 31, thereby effectively preventing the dirt from continuing to enter the drain port 31 and causing the drain port 31 to be blocked. It should be understood here that the larger dirt mentioned should refer to dirt whose size is larger than the diameter of the drain port 31.

[0056] The anti-blocking structure provided by the present invention limits the size of the limited diameter opening and the diameter of the drain port 31, so that the limited diameter opening is smaller than the diameter of the drain port 31, thereby preventing dirt larger than the diameter of the drain port 31 from flowing into the drain port 31 to avoid blockage. Moreover, when dirt is stuck at the limited diameter opening, condensed water can still overflow the limited diameter opening and be discharged from the drain port 31, which not only has an anti-blocking effect, but also does not hinder the discharge of condensed water, thereby improving the drainage efficiency and capacity of the base.

[0057] Further, according to experience, the dirt mixed in the condensed water generally includes dust and insects, etc., and the size of the diameter limit opening is set to 5.85-7.15 mm, preferably 6.5 mm, so as to block the dirt at the diameter limit opening. The diameter of the drain port 31 is set to 12.6-15.4 mm, preferably 14 mm, so that the condensed water on the base can be discharged in time to meet the drainage capacity of the base.

[0058] Furthermore, the drain port 31 is located at the bottom of the water outlet 32 ​​along the gravity direction, and a first inclined surface inclined toward the drain port 31 is provided on the bottom of the water outlet 32, which helps the condensed water to quickly flow into the drain port 31. The first inclined surface can be the bottom wall of the water outlet 32, or a guide plate provided on the bottom wall of the water outlet 32.

[0059] By providing a first inclined surface on the bottom wall of the water outlet 32 ​​, water in the water outlet 32 ​​can be quickly introduced into the drain port 31 , thereby improving the drainage efficiency.

[0060] Furthermore, in order to further improve the drainage efficiency, e.g. Figure 1 , 2 As shown, a water tank 39 is also provided on the lower base 3. The water tank 39 is arranged on the water inlet path of the drain port 31. One end of the water tank 39 is connected to the bottom wall of the drain port 31, and the other end is connected to the bottom wall of the front water channel 34. Condensed water discharged from the front water channel 34 or the outlet 32 ​​first enters the water tank 39 and then is discharged from the drain port 31. In order to drain smoothly, one end of the water tank 39 is inclined toward the drain port 31, so that the water tank 39 has a certain slope. In the present invention, the angle α between the bottom wall of the water tank 39 and the bottom wall of the front water channel 34 is 120°-150°.

[0061] Furthermore, the water tank 39 is provided with a rib 391 extending in the front-to-back direction of the base, and there is an inclination angle β between the rib 391 and the bottom wall of the water tank 39, wherein 45°≤β≤90°. The rib 391 is provided on the water tank 39, and when the condensed water passes through the water tank 39, the debris in the condensed water is blocked by the rib 391. Since one end of the water tank 39 is inclined downward toward the drain outlet 31, the debris in the condensed water is driven by the water flow and gathered in the V-shaped space formed between the rib 391 and the bottom wall of the water tank 39, thereby preventing the debris from entering the drain outlet 31, thereby achieving an anti-blocking effect.

[0062] The number of ribs 391 is at least two rows, and at least two rows of ribs 391 are staggered in the left-right direction on the water tank 39. The staggered arrangement of multiple rows of ribs 391 further increases the resistance to the passage of debris and improves the anti-blocking effect. Figure 6 As shown, a water passing groove 33 is also provided on the lower base 3, and the water passing groove 33 is set on the water flow path between the front water channel and the drain outlet 31. The condensed water enters the water passing groove 33 from the front water channel and then flows into the drain outlet 31, while the dirt mixed in the condensed water cannot pass through the groove wall of the water passing groove 33 and is thus blocked in the water passing groove 33.

[0063] By providing the water passing groove 33, the condensed water flowing out of the front water channel is filtered to prevent dirt from entering the drain port 31 and causing the drain port 31 to be blocked, thereby improving the drainage capacity of the base.

[0064] As shown in the figure, the lower base 3 has a bottom plate assembly, and the water-passing groove 33 is formed by the bottom plate assembly being depressed downward. The bottom plate assembly includes a bottom plate body and a water-passing groove 33. The water-passing groove 33 has a bottom wall and a groove wall enclosed at the edge of the bottom wall. The water-passing groove 33 and the bottom plate body have a smooth transition to facilitate water flow through the water-passing groove 33, and to avoid water flow from the bottom plate into the water-passing groove 33 to cause water flow impact, splashing water to affect other components on the base, or causing water flow turbulence, affecting the drainage effect.

[0065] Furthermore, the bottom wall is smoothly connected to the groove wall, thereby preventing dirt from being blocked at the sharp corner formed by the bottom wall and the groove wall.

[0066] The groove wall includes a left side wall close to the drain outlet 31 and a right side wall away from the drain outlet 31. Furthermore, a second inclined surface inclined toward the drain outlet 31 is provided between the right side wall and the bottom plate to facilitate dirt in the condensed water to enter the water passing groove 33, while it is not easy to follow the condensed water across the water passing groove 33.

[0067] Preferably, in order to further prevent dirt from passing over the water-passing groove 33 and entering the drain port 31 under the inertia of the water flow, an extension portion is provided at the upper end of the left side wall in a direction away from the drain port 31, and the extension portion covers a portion of the water-passing groove 33 to limit dirt from passing out of the water-passing groove 33 without hindering the water flow from overflowing from the water-passing groove 33. It should be understood that the extension portion covers a portion of the water-passing groove 33 in a direction opposite to the water flow.

[0068] Furthermore, the maximum distance between the left and right walls of the water-passing groove 33 is between 11.88 mm and 14.52 mm, preferably 13.2 mm. This arrangement, on the one hand, facilitates the rapid passage of condensed water without affecting the drainage efficiency, and on the other hand, can block certain dirt and has the function of filtering condensed water.

[0069] As another implementation form of the present invention, Figure 7 As shown, a retaining rib 36 is provided on the water outlet 32, and the retaining rib 36 is provided perpendicularly to the water flow direction. A diameter limiting opening penetrating the retaining rib 36 is provided in the upper and lower directions of the retaining rib 36, and condensed water can pass through the diameter limiting opening, but dirt with a diameter larger than the drain port 31 cannot pass through the diameter limiting opening. Preferably, by providing the retaining rib 36 on the water outlet 32, the position of the diameter limiting opening can be set according to the relationship between the water outlet 32 ​​and other components on the lower base 3, so as to facilitate the coordination between the water outlet 32 ​​and other components, and the position of the diameter limiting opening is also optional.

[0070] As another implementation form of the present invention, Figure 1 , 2 As shown, in order to facilitate the installation of the drainage hose, a clearance opening 38 is formed between the drainage port 31 and the outer side wall 322 of the water outlet 32, and the outer side wall 322 is bent inward to form a first clearance side wall 381 and a second clearance side wall 382 respectively. The first clearance side wall 381 and the second clearance side wall 382 are connected in a roughly L-shaped manner, and the second clearance side wall 382 is connected to the outer wall 311 of the drainage port 31. The first clearance side wall 381, the second clearance side wall 382 and the outer wall 311 of the drainage port 31 define the clearance opening 38. The setting of the clearance opening 38 enables the outer side of the drainage port 31 to have a certain operating space when installing the drainage hose, and the installation is convenient. Furthermore, the side of the clearance opening 38 away from the second clearance side wall is set to a flared structure, that is, the distance between the first clearance side wall 381 and the outer wall 311 of the drainage port gradually increases from the inside to the outside. The clearance opening 38 is configured as an expanded structure, so that when the drain hose is installed on the drain opening 31 , there is a larger operating space, which is more conducive to the installation of the drain hose and the drain opening 31 .

[0071] The above description is only a preferred implementation form of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
