[0022] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0023] See also Figure 1-Figure 3 , Figure 1 It is a three-dimensional structural schematic diagram of the water receiving bottom plate of the indoor unit provided by the embodiment of the utility model; Figure 2 It is a schematic diagram of the exploded structure of the water receiving chassis of the indoor unit provided by the embodiment of the utility model; Figure 3 It is a schematic diagram of the partial explosion structure of the drainage baffle in the water receiving bottom plate of the indoor unit provided by the embodiment of the utility model. The water receiving bottom plate 1 of the indoor unit of the utility model comprises a plate body 11 and a drainage baffle 12 arranged inside the plate body 11, the top of the plate body 11 is open, and the bottom is arranged as a downwardly concave arc plate 111, the lowest concave part of the arc plate 111 is located at the center of the arc plate 111, and a drainage pipe 112 is arranged at the center of the arc plate 111, the drainage baffle 12 is spirally distributed, and the drainage baffle 12 can be detached from the arc plate 111, and the drainage baffle 12 comprises a spiral starting end 121 and a spiral ending end 122, the spiral starting end 121 is attached to the side wall of the plate body 11, and the spiral ending end 122 corresponds to the position of the drainage pipe 112.
[0024] By setting the bottom of the disk body 11 as a downwardly concave arc plate 111, and making the lowest concave point of the arc plate 111 located at the center of the arc plate 111, a drain pipe 112 can be set at the center of the arc plate 111, and then when the air conditioner is cooling and produces condensed water, the condensed water falls into the disk body 11 and flows toward the center along the arc plate 111, and is finally discharged from the drain pipe 112.
[0025] By setting the spiral drain baffle 12 on the arc plate 111, and making the starting end 121 fit the side wall of the arc plate 111, and the ending end 122 corresponds to the position of the drain pipe 112, the condensed water carried on the arc plate 111 can flow along the spiral drain baffle 12 when flowing toward the drain pipe 112, and finally be discharged from the drain pipe 112.
[0026] Since the drain pipe 112 is arranged at the center position of the water receiving base 1, and the bottom of the water receiving base 1 is an arc-shaped plate 111, the time for condensed water to flow to the drain pipe 112 can be shortened, thereby improving the drainage efficiency. Since the drain baffle 12 is spirally distributed, when the condensed water in the water receiving tray increases, the condensed water can be accumulated at different positions of the drain baffle 12, that is, the condensed water accumulates at different spiral positions of the drain baffle 12, and the condensed water will not overflow directly from the water receiving tray, thereby preventing the air conditioner from dripping.
[0027] In the above embodiment, the disk body 11 includes any one of a circular disk body 11, a square disk body 11 and a polygonal disk body 11. As a preferred embodiment, the disk body 11 is a square disk body 11, the drainage baffle 12 is distributed in an elliptical spiral, and the starting end 121 is attached to the side wall of the disk body 11 in the length direction.
[0028] Since the disk body 11 is a square disk body 11, the square disk body 11 can be set inside a square air-conditioning indoor unit, and the size of the disk body 11 can be set as large as possible according to the size of the air-conditioning indoor unit to increase the volume of the water receiving bottom plate 1, so that the water receiving bottom plate 1 can accumulate more condensed water, further avoiding the phenomenon of condensed water overflow.
[0029] In an embodiment of the utility model, the arc plate 111 has a smooth transition as a whole. In the length direction, the height of both sides of the arc plate 111 is higher than the height of the center position. In the width direction, the height of both sides of the arc plate 111 is higher than the height of the center position.
[0030] Since the arc plate 111 has a smooth transition as a whole, and the heights of both sides of the arc plate 111 in the length direction are higher than the height of the center position, the heights of both sides of the arc plate 111 in the width direction are higher than the height of the center position, and the heights of the surroundings of the arc plate 111 are higher than the height of the center position, it is convenient for condensed water to flow to the center position at any position on the arc plate 111, and the smooth transition surface of the arc plate 111 makes the condensed water flow more smoothly, thereby improving the drainage efficiency of the water receiving chassis 1.
[0031] In an embodiment of the utility model, the surface of the arc plate 111 is coated with a hydrophobic layer, and the hydrophobic layer includes any one of a fluorinated polyethylene hydrophobic layer, a fluorocarbon wax hydrophobic layer, and a polyolefin hydrophobic layer, so as to prevent condensed water from remaining on the surface of the arc plate 111 and causing scaling or bacterial growth under the action of the hydrophobic layer, thereby improving the cleanliness of the air conditioner indoor unit.
[0032] See also Figure 2 In an embodiment of the utility model, a protruding slot 113 is provided on the surface of the arc plate 111 , and the width of the slot 113 is adapted to the thickness of the drainage baffle 12 so that the drainage baffle 12 can be plugged and fixed on the arc plate 111 .
[0033] By fixing the slot 113 on the surface of the arc plate 111 and making the width of the slot 113 match the thickness of the drain baffle 12, the drain baffle 12 can be fixed on the arc plate 111 by being plugged into the slot 113. When the docking water bottom tray 1 needs to be disassembled and cleaned, the tray body 11 can be disassembled from the air conditioner indoor unit and the drain baffle 12 can be pulled out from the slot 113, so that the user can clean the tray body 11 and the drain baffle 12 separately, thereby reducing the difficulty of cleaning the docking water bottom tray 1 and making it easier for the user to clean the docking water bottom tray 1.
[0034] In the embodiment of the present utility model, a sealing layer is provided on the surface where the slot 113 and the drainage baffle 12 are in contact.
[0035] By providing a sealing layer on the slot 113, after the drain baffle 12 is inserted into the slot 113, the sealing layer can be fitted with the surface of the drain baffle 12 to increase the insertion firmness between the drain baffle 12 and the slot 113, and at the same time, it can also prevent condensed water from flowing into the slot 113 through the gap and causing scale to be produced in the slot 113 by the condensed water.
[0036] See also Figure 3 In an embodiment of the utility model, the drain baffle 12 is a hollow plate, and a heating wire 123 is arranged inside the drain baffle 12 , and a plug connector 124 electrically connected to the heating wire 123 is arranged on the drain baffle 12 .
[0037] By setting the heating wire 123 inside the hollow drainage baffle 12 and electrically connecting the plug connector 124 to the heating wire, after plugging the plug connector 124 into the socket on the air conditioner indoor unit, the user can control the heating wire 123 to heat and dry the condensed water or water stains in the water tray, thereby further improving the drainage efficiency of the water receiving bottom tray 1 and preventing the condensed water from scaling in the tray body 11.
[0038] In an embodiment of the present utility model, the bottom of the drain baffle 12 is an opening, and the heating wire 123 is installed inside the drain baffle 12 from the bottom opening of the drain baffle 12 .
[0039] By setting the bottom of the drain baffle 12 as an opening, the heating wire 123 can be easily installed into the interior of the drain baffle 12 from the opening. After the drain baffle 12 is inserted into the slot 113, the slot 113 can close the bottom opening of the drain baffle 12 to ensure the heating effect of the heating wire 123. At the same time, the closing of the slot 113 and the sealing effect of the sealing layer can prevent condensed water from penetrating into the slot 113 and affecting the heating effect of the heating wire 123.
[0040] In an embodiment of the utility model, the drain baffle 12 includes any one of an aluminum drain baffle 12, a copper drain baffle 12, and a stainless steel drain baffle 12, so as to ensure that the drain baffle 12 has a strong structural strength and anti-rust function, thereby avoiding deformation of the drain baffle 12 and making it impossible to plug the drain baffle 12 into the slot 113, and at the same time avoiding the problem of rust caused by the drain baffle 12 being in contact with condensed water for a long time.
[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
