The drainage assembly comprises a drainage valve 300 and a mandril 500; wherein, the mandril 500 is movably arranged in the drainage cavity 140; the drain valve 300 is connected to the push rod 500 to drive the push rod 500 to move to open and close the first drain port 120.

Specifically, the water receiving tank 110 of the base plate 100 may be used to store condensed water generated by the heat exchange component. The bottom plate 100 is configured to form a drain chamber 140 at one side of the water receiving tank 110, and a bottom wall or a side wall of the drain chamber 140 is configured with the first drain port 120. Specifically, the first drain port 120 is provided at a lower end of one sidewall of the drain chamber 140 opposite to the drain valve 300. The base plate 100 is further constructed with a mounting groove 160 on the outside of the drain chamber 140 to which the drain valve 300 is mounted. Since the drain valve 300 is the electronic drain valve 300, the drain valve 300 is installed in the installation groove 160 at the outer side of the drain chamber 140, and the damage caused by the wetting of the water in the drain chamber 140 can be avoided.

The drain valve 300 includes a valve seat 310 and a valve shaft 320 connected to the valve seat 310; wherein, the valve seat 310 is fixed in the mounting groove 160 and covered by a protective cover 400, the protective cover 400 is made of flame-retardant and fireproof material to protect the valve seat 310; the valve shaft 320 penetrates outward from the mounting groove 160 and extends above the drain chamber 140, and is connected to the upper end of the stem 500. The lower end of the stem lifter 500 extends to the bottom of the drain chamber 140 and corresponds to the first drain port 120 on the sidewall of the drain chamber 140.

When the first drain opening 120 needs to be closed, the drain valve 300 is opened, the valve seat 310 of the drain valve 300 drives the valve shaft 320 to move along the axial direction of the valve shaft in the direction away from the valve seat 310, so that the push rod 500 is pushed to approach the first drain opening 120, and the push rod 500 realizes closing of the first drain opening 120 until the lower end of the push rod 500 correspondingly blocks the first drain opening 120.

When the first drain opening 120 needs to be opened, the drain valve 300 is opened, the valve seat 310 of the drain valve 300 drives the valve shaft 320 to move in the reverse direction, so that the push rod 500 is pushed to move in the direction away from the first drain opening 120, until the lower end of the push rod 500 is completely evacuated from the first drain opening 120, the push rod 500 opens the first drain opening 120, water in the water receiving tank 110 flows to the first drain opening 120 through the water flow channel, then flows into the drain cavity 140 from the first drain opening 120, and finally is discharged to the outside of the air conditioner from the drain cavity 140.

The technical scheme of the utility model, through constructing drainage chamber 140 on chassis 100, construct the first drain 120 that communicates with water receiving tank 110 on this drainage chamber 140, and dispose drainage component on chassis 100, wherein, drainage chamber 140 is located movably to drainage component's ejector pin 500, drainage component's drain valve 300 is installed in the outside of drainage chamber 140, drain valve 300 is connected with ejector pin 500, with through the first drain 120 of the activity of drain valve 300 drive ejector pin 500 and switch, thereby need not the first drain 120 of user's manual switch, effectively improve the convenience of air conditioner drainage.

Referring to fig. 4 to 6, in an embodiment, the drain valve 300 includes a valve seat 310 and a valve shaft 320 connected to the valve seat 310; the stem 500 includes a first rod 510 connected to the valve shaft 320, and a second rod 520 extending downward from the end of the first rod 510 for opening and closing the first drain port 120, and the lower end of the second rod 520 is slidably mounted at the bottom of the drain chamber 140.

Specifically, the first rod 510 of the push rod 500 extends in the same direction as the valve shaft 320 of the drain valve 300; the second rod 520 of the push rod 500 extends downwards to the bottom of the drainage chamber 140 from the end of the first rod 510 far away from the valve shaft 320, and the lower end of the second rod 520 is slidably mounted at the bottom of the drainage chamber 140. When the drain valve works, the valve shaft 320 of the drain valve 300 moves along the axial direction thereof, thereby driving the push rod 500 to slide back and forth, and further realizing that the push rod 500 is close to or far away from the first drain opening 120, and further realizing opening and closing of the first drain opening 120.

Referring to fig. 6, 13 and 14, for the way that the top rod 500 blocks the first drainage port 120, a plug 521 may be protruded on the top rod 500, so that the first drainage port 120 is correspondingly blocked by the plug 521 to close the first drainage port 120; alternatively, a cover may be provided on the plunger 500 to cover the first drain 120 with the cover, so as to close the first drain 120. In the present embodiment, the first design manner is adopted. Specifically, a plug 521 opposite to the first drain 120 is protruded at a side surface of the second rod 520 of the plunger 500, so that the first drain 120 is opened and closed by the plug 521. The plug 521 is designed in a convex column shape, and the outer diameter of the plug 521 is equal to or larger than that of the first drain 120, so that the plug 521 can completely plug the first drain 120.

It is considered that, when the plug 521 blocks the first drain opening 120, the plug 521 and the periphery of the first drain opening 120 may not be in complete contact with each other for sealing, and a narrow gap may be formed therebetween, and the existence of the gap may cause water to leak from the gap. Therefore, in order to reduce the occurrence of the above situation, the drainage assembly further comprises a sealing cap 600, and the sealing cap 600 is sleeved on the plug 521 of the top rod 500.

Specifically, the sealing cap 600 is made of a sealing material having flexibility or elasticity so that the sealing cap 600 can be deformed. When the plug 521 plugs the first drain 120, the sealing sleeve 600 is embedded between the plug 521 and the periphery of the first drain 120, and the sealing sleeve 600 deforms to enable the plug 521 to be abutted to the periphery of the first drain 120 more tightly, so that a gap is prevented from being formed between the plug 521 and the periphery of the first drain 120, the plug 521 is in interference fit with the first drain 120, and the sealing performance in the state of closing the first drain 120 is effectively improved.

Referring to fig. 6 to 9, in an embodiment, to facilitate the movement of the push rod 500, a guide groove 141 corresponding to the first drain port 120 is formed on the bottom surface of the drain cavity 140; the lower end of the push rod 500 is slidably disposed in the guide groove 141 to open and close the first drain port 120 by being driven to slide along the guide groove 141 by the drain valve 300.

Specifically, the extending direction of the guide groove 141 coincides with the extending direction of the valve shaft 320 of the water discharge valve 300. The transverse width of the guide groove 141 may be selected to be the same as the width of the second rod body 520 of the push rod 500, so that the groove walls at both sides of the guide groove 141 cooperate to limit the movement of the push rod 500 in the direction perpendicular to the extending direction of the guide groove 141, so that the second rod body 520 is not easily deviated to the left and right sides, and the plug 521 on the second rod body 520 is prevented from being staggered with the first drain port 120.

Referring to fig. 6, 7 and 11, in an embodiment, in order to facilitate water in the water receiving tank 110 to enter the water discharging cavity 140 through the first water discharging opening 120, optionally, a lower hole edge of the first water discharging opening 120 is designed to be higher than a bottom surface of the guide groove 141, so that a height difference is formed between the bottom surfaces of the first water discharging opening 120 and the guide groove 141, and the water passing through the first water discharging opening 120 is facilitated to enter the water discharging cavity 140.

Since the height difference is formed between the lower hole edge of the first drainage port 120 and the bottom surface of the guide groove 141, in order to ensure that the ejector rod 500 can be accurately aligned with the first drainage port 120 in the moving process, optionally, a guide rib 522 is convexly arranged on the lower end surface of the second rod body 520, and the guide rib 522 abuts against the bottom surface of the guide groove 141, so that the plug 521 and the first drainage port 120 are located at the same height position.

Specifically, the guiding rib 522 on the lower end surface of the second rod 520 abuts against the bottom surface of the guiding groove 141, so that the push rod 500 always slides along the guiding groove 141 during the moving process, and is not easy to tilt up or deviate downwards, and the plug 521 of the push rod 500 is always kept corresponding to the first drain opening 120 during the moving process. Moreover, for the lower end surface of the second rod 520, the contact area between the guiding rib 522 and the bottom surface of the guiding groove 141 is small, and the friction force generated between the guiding rib and the bottom surface is small, so that the sliding difficulty of the push rod 500 can be reduced, the push rod 500 can be driven by the drain valve 300 with small driving force, and the push rod 500 can slide easily.

In one embodiment, considering that the lateral width of the guide groove 141 may be selected to be identical to the width of the second rod body 520 of the carrier rod 500, the notch of the guide groove 141 easily interferes with the carrier rod 500 during the sliding of the carrier rod 500 into the guide groove 141, so that the carrier rod 500 slides into the guide groove 141.

Here, to solve the above problem, an end of the guide groove 141 away from the first drain port 120 may be flared to form a guide port 142 guiding the lower end of the plunger 500 into and out of the guide groove 141 at the flare. The width of the guide opening 142 is larger than the width of the guide groove 141, so that the sidewalls of both sides of the guide opening 142 are less likely to interfere with the plunger 500, thereby facilitating the second rod 520 guiding the plunger 500 to enter the guide groove 141 from the guide opening 142.

Referring to fig. 11 to 13, according to any one of the above embodiments, there may be various designs for the connection between the plunger 500 of the drainage assembly and the drainage valve 300. In this embodiment, the first rod 510 of the push rod 500 is configured with a mounting joint 530, and the inside of the mounting joint 530 is configured with a top cavity 531 (as shown in fig. 15); the valve shaft 320 of the water discharge valve 300 is inserted into the top chamber 531, and is fixedly coupled to the mounting adapter 530.

Specifically, the inner diameter of the top chamber 531 of the mounting adapter 530 is equal to the outer diameter of the valve shaft 320 of the water discharge valve 300, so that the valve shaft 320 and the top chamber 531 are fittingly inserted, and the end surface of the valve shaft 320 contacts the bottom surface of the top chamber 531. The portion of the valve shaft 320 located outside the top cavity 531 is connected and fixed with the mounting joint 530, specifically, the two may be connected by passing through a screw, or a snap structure may be configured on the two to be connected by snap-fit through the snap structure.

Referring to fig. 11-15, in one embodiment, the mounting adapter 530 is further configured with a positioning cavity 532 located at an inlet end of the top cavity 531, the positioning cavity 532 having an inner diameter greater than the inner diameter of the top cavity 531; the valve shaft 320 is inserted into the top cavity 531 through the positioning cavity 532, and a portion of the valve shaft 320 corresponding to the positioning cavity 532 is fixedly connected to a sidewall of the positioning cavity 532. Wherein, a positioning protrusion 321 is protruded towards the lateral direction at the part of the valve shaft 320 corresponding to the positioning cavity 532; the sidewall of the positioning cavity 532 has a positioning bayonet 533 extending therethrough, and the positioning bayonet 533 is used for the positioning protrusion 321 to be inserted and fixed.

Specifically, the positioning protrusion 321 may be an elastic buckle, and when assembling, the elastic buckle is pressed first to make the valve shaft 320 enter the positioning cavity 532, until the valve shaft 320 is inserted into the top cavity 531, the elastic buckle just reaches the positioning bayonet 533, and the elastic buckle recovers elasticity to be clamped into the positioning bayonet 533, so as to achieve connection and fixation of the two. However, considering that the elastic clip may not have enough strength and stability, the positioning protrusion 321 may be a bump integrated with the valve shaft 320, and apply a large force to the valve shaft 320, so that the positioning protrusion 321 is pushed into the positioning notch 533 of the positioning cavity 532 against the binding force of the opening periphery of the mounting adapter 530.

Further, to facilitate insertion of the valve shaft 320 into the mounting adapter 530, a guide 322 is configured along a circumference of a portion of the valve shaft 320 corresponding to the positioning cavity 532, the guide 322 being frustoconical in shape adapted to guide the valve shaft 320 into the positioning cavity 532; the positioning protrusion 321 is protruded from a side surface of the guide portion 322. Specifically, the outer diameter of the guide portion 322 gradually decreases along the direction of inserting the valve shaft 320 into the mounting joint 530, so that the guide portion 322 is disposed in a frustum shape, the front end of the guide portion 322 is small and is not easily interfered with the opening periphery of the mounting joint 530, and the guide portion 322 is further beneficial to guiding the valve shaft 320 into the positioning cavity 532.

That is, the stopping portion 323 and the positioning protrusion 321 are respectively engaged from the inner side and the outer side of the mounting joint 530, so as to limit the valve shaft 320 on the mounting joint 530, thereby ensuring that the valve shaft 320 is stably connected with the push rod 500 all the time in the process that the push rod 500 is driven by the valve shaft 320 to move, preventing the valve shaft 320 from falling off, and improving the stability of connection between the valve shaft 320 and the push rod 500.

Referring to fig. 11, in an embodiment, the rod 500 further includes a rib 540 located on a side of the first rod 510 opposite to the plug 521, and the rib 540 connects the first rod 510 and the second rod 520. The reinforcing rib plate 540 can reinforce the strength of the carrier rod 500, so that the carrier rod 500 is not easily stressed to bend.

According to any of the above embodiments, the water in the drainage chamber 140 of the chassis 100 can be directly drained to the outside. Specifically, the base plate 100 is further provided with a second drain opening 130 communicated with the drain cavity 140, the second drain opening 130 is located on the lower surface of the base plate 100, and the water in the drain cavity 140 can be drained from the second drain opening 130.
