Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and in particular to an indoor unit base and an air conditioner. Background Art

[0002] With the development of social economy, air conditioning has become an important part of people's office and life. Traditional light commercial dual-use air conditioners need to be installed in both a standing and hanging manner, so the structure of the water tray and its installation environment requirements are relatively complex.

[0003] Most of the cranes on the market use traditional gravity drainage methods, such as Figure 1 As shown, the water receiving pan is an integral structure composed of two mutually perpendicular surfaces, and a drain port is set at the intersection of the two surfaces. When the unit is hoisted, condensed water accumulates in one side of the water receiving pan and is discharged from the drain port; when the unit is installed, condensed water accumulates in the other side of the water receiving pan and is also discharged from the drain port. The current solution can only rely on gravity drainage, and there is no height difference between the two drainage surfaces and the drain port, which makes drainage difficult, resulting in a large amount of condensed water stored in the water receiving pan.

[0004] In addition, if Figure 2 As shown, the water storage part of the inner surface of the water receiving tray is a smooth inclined surface, and a protective pad (sponge strip) is attached to the contact surface between the water receiving tray and the evaporator to ensure that the evaporator fins are not damaged by gravity. During the operation of the machine body, the generated water flows from the end of the water guide plate close to the air outlet to the end close to the water collecting tank. Since the protective pad (sponge strip) is compressed, the water permeability is poor and the water leakage rate of the machine body is high, which affects the user experience and reduces the product quality. Summary of the invention

[0005] The invention discloses a water receiving pan drainage structure and a seat crane. A wave-shaped drainage structure is arranged at the position where a protective pad is arranged on the water receiving pan, so as to improve the drainage efficiency on the water receiving pan.

[0006] In order to solve the above problems, the present invention provides a water receiving tray drainage structure, including a water receiving tray, the water receiving tray including a water guide plate and a water collecting trough, a protective pad is arranged on the water guide plate, and a drainage structure is arranged at the contact position between the protective pad and the water guide plate, the drainage structure is used to drain the condensed water at the protective pad on the water receiving tray to the water collecting trough.

[0007] The arrangement is achieved by arranging a convex or concave drainage structure at the contact position between the protective pad and the water receiving tray, so that the protective pad and the water storage part of the inner surface of the water receiving tray are in a non-close-fitting state, and a water holding portion is formed between the drainage structure and the inner surface of the water receiving tray, thereby improving the water permeability of the protective pad, so that condensed water flowing through the protective pad can quickly flow to the water holding portion, and the water holding portion of the drainage structure is connected to the water collecting tank, and condensed water dripping from the evaporator to the water receiving tray can quickly flow through the sponge pad and flow to the water collecting tank, thereby avoiding mold contamination at the sponge or dripping at the back plate, thereby reducing the probability of water leakage from the machine body.

[0008] Preferably, the drainage structure is arranged on the water guide plate, and the drainage structure is provided with protrusions and / or grooves.

[0009] This arrangement provides a raised or sunken drainage structure at the contact position between the protective pad and the water receiving tray, so that the protective pad and the water storage portion of the inner surface of the water receiving tray are in a non-close-fitting state, ensuring that condensed water dripping from the evaporator onto the water receiving tray can quickly flow through the sponge pad and flow into the water collection tank, thereby improving the drainage efficiency of the water receiving tray and increasing product competitiveness.

[0010] Preferably, a water collecting plate is provided at one end of the water diversion plate, and the water collecting groove is formed at the connection between the water collecting plate and the water diversion plate.

[0011] On the one hand, this arrangement increases the efficiency of the condensed water on the water receiving tray flowing to the water collecting tank, and on the other hand, it also ensures the reliability of the condensed water flowing through the protective pad to avoid water leakage.

The structure is simple, and the condensed water is discharged from the water receiving tray through the height difference, preventing the condensed water from contacting the internal circuit, thereby improving the overall performance of the crane.

[0015] Preferably, the drainage structure is an elongated wave structure as a whole.

[0016] By setting up a wave-shaped drainage structure, the continuity of the condensed water flow is ensured and the drainage efficiency of the drainage structure is improved.

[0018] This arrangement facilitates the collection of condensed water dripping from various angles of the evaporator. By providing a step structure at at least one end of the drainage portion, the flow of condensed water at the connection between the two ends of the drainage portion and the first end plate and / or the second end plate is facilitated. In the hoisting state, the water collection trough is provided at the lower side of the drainage structure. The water collection trough is located at the lowest point on the water receiving tray, thereby further improving the drainage efficiency of the water receiving tray.

DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figures 3 to 9 As shown, the present application provides a water receiving tray drainage structure, including a water receiving tray 1, a protective pad 3 is arranged on the water receiving tray 1, and a drainage structure 106 is arranged at the contact position between the protective pad 3 and the water receiving tray 1, and the drainage structure 106 is arranged in the form of protrusions and / or grooves. The drainage structure 106 is used to guide the condensed water at the protective pad 3 on the water receiving tray 1 and discharge it to the water collecting tank 105 on the water receiving tray 1.

[0042] like Figure 3 , Figure 4 , Figure 8 and Fig. 9As shown, in the drainage structure of the water receiving pan disclosed by the present invention, the evaporator 2 is installed obliquely in the accommodating cavity of the water receiving pan 1, and the condensed water generated on the evaporator 2 flows into the inside of the water receiving pan 1 and is discharged through the water receiving pan 1. In the prior art, the water storage portion of the inner surface of the water receiving pan 1 is a smooth inclined surface. In order to prevent the contact between the evaporator 2 and the water storage portion of the water receiving pan from being damaged due to the influence of gravity on the evaporator fins, a protective pad 3 is provided at the contact between the evaporator 2 and the water receiving pan 1. The protective pad is generally made of a flexible material, such as a sponge strip or other foamed plastic polymer. When the whole machine is running, the condensed water dripping from the evaporator into the water receiving pan 1 flows into the water collecting tank 105. Since the protective pad 3 provided at the contact between the evaporator 2 and the water receiving pan 2 is compressed and has poor water permeability, the protective pad 3 and the water receiving pan 1 are connected to each other. A convex or concave drainage structure 106 is provided at the contact position of the protective pad 3 and the water storage part of the inner surface of the water receiving tray 1, so that the protective pad 3 and the water storage part of the inner surface of the water receiving tray 1 are in a non-close contact state, and a water containing part is formed between the drainage structure 106 and the inner surface of the water receiving tray 1, thereby improving the water permeability of the protective pad 3, so that the condensed water flowing through the protective pad 3 can quickly flow to the water containing part, and the water containing part of the drainage structure 106 is connected with the water collecting tank 105. The condensed water dripping from the evaporator to the water receiving tray 1 can quickly flow through the sponge pad and flow to the water collecting tank, thereby avoiding mold contamination at the sponge or dripping at the back plate, and reducing the probability of water leakage of the body.

[0043] The drainage structure of the water receiving tray described in the present invention, the water receiving tray 1 includes a water diverter plate 101 and a water collecting plate 102, the water diverter plate 101 and the water collecting plate 102 are arranged at an angle, a first end plate 103 is arranged at one end of the water diverter plate 101 and the water collecting plate 102, and a second end plate 104 is arranged at the other end of the water diverter plate 101 and the water collecting plate 102, the water collecting trough 105 is formed at the connection between the water collecting plate 102 and the water diverter plate 101, the drainage structure 106 is arranged on the side of the water collecting trough 105 away from the water collecting plate 102, and the drainage structure 106 is arranged on the water diverter plate 101.

In the hoisting state, the water collecting tank 105 is arranged at the lower side of the drainage structure 106, and the water collecting tank 105 is located at the lowest point on the water collecting pan 1. On the one hand, this setting increases the efficiency of the condensed water on the water collecting pan flowing to the water collecting tank, and on the other hand, it also ensures the reliability of the condensed water flowing through the protective pad 3 to avoid water leakage.

[0045] Preferably, as a preferred embodiment of the present invention, the drainage structure 106 and the water guide plate 101 are integrally formed.

[0046] This arrangement facilitates the processing and manufacturing of the water receiving tray and reduces production costs. As another example of the present invention, if the drainage structure 106 is a convex arrangement, the drainage structure 106 can also be bonded or detachably fixed on the upper surface of the water guide plate 101.

The protective pad 3 is bonded to the drainage structure 106, and a water receiving portion is formed between the protective pad 3 and the upper surface of the water guide plate 101. If the drainage structure 106 is a concave arrangement, a groove needs to be provided on the water guide plate 101 to accommodate and fix the drainage structure 106. The drainage structure is bonded or detachably fixed in the groove, the protective pad 3 is bonded to the drainage structure 106, the condensed water on the upper surface of the water guide plate 101 flows into the groove accommodating the drainage structure 106, and the condensed water on the protective pad 3 also flows into the groove. The condensed water in the groove flows to the water collecting tank 105 under the action of its own weight; the drainage structure 106 and the water guide plate 101 are integrally formed, and the drainage structure 106 is a raised block or a recessed hole, which reduces the assembly steps and ensures the reliability of the condensed water flowing to the water collecting tank 105 through the drainage structure.

[0047] Preferably, as a preferred embodiment of the present invention, the drainage structure 106 is designed as a long strip of wave structure as a whole.

[0048] Since the contact surface between the evaporator 2 and the water receiving tray 1 is in a long strip shape, the drainage structure 106 on the water guide plate 101 is also designed to be long strip-shaped, ensuring that the condensed water dripping from the evaporator 2 on the water guide plate 101 can flow to the water collecting tank 105 through the drainage structure 106, and the drainage structure is set in a continuous wave structure, such as Figure 6 As shown, by providing a wave-shaped drainage structure, the continuity of the condensed water flow is ensured and the drainage efficiency of the drainage structure is improved.

[0050] This arrangement forms a step shape at the connection between the water diversion part 1011 and the drainage part 1010 on the water diversion plate 101. On the one hand, it is convenient for condensed water on the water diversion part 1011 to flow to the drainage part. On the other hand, it is also convenient to accommodate and fix the protective pad 3 to ensure the continuity of the condensed water when flowing on the water diversion plate 101.
