AI Technical Summary
In a direct expansion air conditioning system, condensate condenses into small water droplets when it comes into contact with a cold water tray or a direct expansion coil, which adheres to the surface of the coil, resulting in accumulation of condensate. If it is not discharged in time, it will lead to bacterial growth and water tray corrosion, affecting service life and air purification quality.
A direct expansion air conditioner embedded in sink bottom tilt water tray assembly is designed, including an inclined water tray, a sunken pedestal plate, a water tray slide and a condensate pipe. The inclined water tray has a drainage trough and a drainage trough. The condensed water converges to the drainage trough through the inclined part, flows along the drainage trough to a low point, and finally discharges through the condensate pipe at the bottom of the drainage trough.
The rapid flow and gathering of condensate water is achieved, and the timely discharge of condensate water is prevented from growing bacteria, prolong the service life of the water tray, and improve the quality of air purification.

Technical Field
[0001] The present application relates to the technical field of air conditioning, and in particular to an embedded bottom-sunken inclined water pan assembly for a direct expansion air conditioner. Background Art
[0002] Direct expansion units are special equipment used for cooling, heating, humidifying, purifying, and transporting air. They are an important component of central air-conditioning systems and are widely used in commerce, medicine, electronics and other industries.
[0003] The most basic functions of a direct expansion air conditioning cabinet are cooling and heating. During cooling, due to the relatively high humidity and temperature, the dew point temperature is reached the moment it contacts the cold water coil or direct expansion coil, and it will condense into small water droplets attached to the surface of the coil. As the condensed water accumulates, it will flow into the water pan along the coil. If it is not drained in time, it will cause the growth of bacteria and corrosion to the water pan over time, thus affecting the service life of the water pan and the quality of purified air.

[0040] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0041] Reference Figure 1-5 The embedded bottom inclined water pan assembly for direct expansion air conditioner comprises an inclined water pan 1, a water pan slide 2, a sunken cushion plate 3, and a condensing water pipe 5. There are at least two water pan slides 2, water pan slides 2 are arranged on both sides of the inclined water pan 1, a sunken cushion plate 3 is arranged between the two water pan slides 2, and the condensing water pipe 5 is arranged on the bottom of the inclined water pan 1.
[0042] In order to simplify the installation steps and time, the present application adopts a sandwich stack installation method, and the order of installation from bottom to top is the water pan slide 2, the inclined water pan 1, and the sunken cushion plate 3. A set of self-tapping screws are used to fix the three, and bolts can also be used to fix them; then the fixed components are fixed to the base 9 of the direct expansion air conditioning unit with self-tapping screws, and the foam plates 8 on both sides are used to press and fix them, and finally the evaporation coil assembly 7 is fixed to the sunken cushion plate 3. The evaporation coil assembly 7 is a product on the market and is a prior art, so it will not be repeated.
[0043] The inclined water pan 1 adopts a groove structure and has two sets of side surfaces that are opposite to each other. Each side positioning hole of the inclined water pan 1 is respectively connected to a water pan slide 2. The water pan slide 2 adopts a Z-shaped structure, which just makes the overall inclined water pan present a structure embedded under the foam board 8, thereby saving space and reducing costs.
[0044] The water tray slide 2 adopts a Z-shaped structure and a flange design; at the same time, the strength of the structure can be increased to ensure the stability of the equipment.
[0045] The inclined water tray 1 includes two inclined parts 10, a drainage groove 11, and a drain groove 12; the drainage groove 11 is arranged between the two inclined parts 10, and the depth of the inclined part 10 relative to the opening of the groove structure gradually deepens from a position far from the drainage groove 11 to a position close to the drainage groove 11, so that the condensed water can be gathered to the drainage groove 11 through the inclined part 10. The width of the drainage groove 11 gradually narrows from one end to the other end, and the narrower end of the drainage groove 11 is connected to the drain groove 12, and the opening width at the bottom of the drain groove 12 is less than or equal to the diameter of the condensed water pipe 5. The drain groove 12 is connected to the condensed water pipe 5 by the bottom opening. When the condensed water gathered in the drainage groove 11, it will flow down along the drainage groove 11, and finally flow to the condensed water pipe 5 at the bottom of the drain groove 12 and be discharged.
[0046] The condensate pipe 5 is a 90° elbow, and can also be embedded and connected to the base 9 of the direct expansion air conditioning unit.
[0047] The condensate pipe 5 and the drain groove 12 are connected by welding.
[0048] As another connection method, the connection method between the condensate pipe 5 and the drain groove 12 can also be a threaded connection.
[0049] Both ends of the sunken seat plate 3 are provided with connecting parts 4 for connecting to the inclined water pan 1. The sunken seat plate 3 is arranged across the inclined water pan 1 and is connected to the two side edges of the inclined water pan 1. The sunken seat plate 3 adopts a sunken setting, thereby ensuring that condensed water does not overflow from the inclined water pan 1, thereby preventing water leakage from the box body; and the sunken seat plate 3 is not in direct contact with the bottom of the inclined water pan 1, so that the condensed water can flow into the bottom condensed water pipe 5 at the lowest point without hindrance, avoiding corrosion of the sunken seat plate 3, and reducing the choice of corrosion resistance level of the sunken seat plate 3, thereby saving costs and extending the service life.
[0050] The sunken cushion plate 3 adopts a U-shaped structure, and the edge of the U-shaped structure is set as an inwardly turned edge structure to further increase the strength.
[0051] Since the temperature of condensed water in the drain pan is relatively low, condensation may occur on the outer surface of the drain pan body. Therefore, an insulation layer 6 is provided on the outer surface of the inclined water pan 1. The insulation layer 6 is a 5mm thick PE insulation cotton to avoid this phenomenon.
[0052] The material of the inclined water pan 1 is not limited, and is preferably galvanized steel plate, stainless steel, etc., which is formed by bending the sheet metal. The gap can be welded by argon arc welding and then treated with anti-corrosion paint.
[0053] The specific working principle is:
[0054] The condensed water on the evaporating coil assembly 7 can flow to the inclined water pan 1 below, and then flow along the inclined portion 10 and the drainage groove 11, and the condensed water is gathered in the drainage groove 11, and the drainage groove 11 then discharges the gathered condensed water in time through the condensed water pipe 5 at the bottom of the drainage groove 12; since the inclined portion 10, the drainage groove 11, and the drainage groove 12 have an inclined angle, the condensed water can flow and gather quickly during the whole process, and then the condensed water is discharged in time, and no siltation will occur, thereby preventing the growth of bacteria, and improving the service life of the water pan and the quality of air purification; and the condensed water will not soak into the sunken cushion plate 3, thereby increasing the service life of the sunken large inclined water pan 1 for the direct expansion machine, and at the same time, the overall water pan structure is sunk and embedded in the foam plate and the base, which not only saves the cost of the foam plate, but also increases the service life of the overall structure.
[0055] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
