[0022] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.
[0023] The air conditioner according to an embodiment of the present application is described below with reference to the accompanying drawings. Figure 1
[0024] The air conditioner according to an embodiment of the present application is described below with reference to the accompanying drawings. Figure 1 The air conditioner according to an embodiment of the present application is described below with reference to the accompanying drawings.
[0025] According to the air conditioner provided by the embodiment of the present application, the evaporator 3 is arranged in a flat plate structure and at an angle with the horizontal direction, so that when the air flow passes through the evaporator 3, the evaporator 3 can guide and comb the air flow, so that the air flow can flow more evenly through the surface of the evaporator 3, and the heat exchange efficiency of the evaporator 3 is not affected by the uneven heat exchange in the local part. In addition, the inclined evaporator 3 is also convenient for the condensed water to flow down along the inclined surface and be discharged to the water pan 4, effectively preventing the water accumulation in the evaporator 3, reducing the hidden danger of affecting the air conditioner use and indoor air quality caused by the water accumulation breeding bacteria and mold. At the same time, the water pan 4 arranged adjacent to the base 1 in the width direction of the base 1 also makes at least part of the water pan 4 deviate from the air inlet 6 in the up-down direction, so that the resistance of the air flow passing through the water pan 4 is smaller, and the energy efficiency ratio of the air conditioner is higher.
[0026] Need to be explained, as Figure 1 The opening of the air inlet 6 is arranged downward, the opening of the air outlet 7 is arranged forward, and the upper end and the lower end of the evaporator 3 extend to the front panel 2 and the base 1 respectively.
[0027] In some embodiments, as Figure 1 The inner surface of the mounting cavity 5 includes a first surface 11 arranged on the base 1, the first surface 11 is opposite to the front panel 2 along the width direction of the base 1, and the evaporator 3 extends in the direction adjacent to the first surface 11 from top to bottom.
[0028] At this time, the evaporator 3 is less likely to interfere with other components in the air conditioner, and the layout of the air conditioner is compact. At the same time, the water pan 4 arranged adjacent to the first surface 11 can have a smaller width, and the water pan 4 does not occupy too much unnecessary space to affect the air inlet area, so that the refrigeration and heating efficiency of the air conditioner is higher.
[0029] In some embodiments, one end of the evaporator 3 in the length direction of the base 1 is connected with the base 1 through the first fastener, and the other end of the evaporator 3 in the length direction of the base 1 is inserted and matched with the base 1.
[0030] That is, after one end of the evaporator 3 is inserted and matched with the base 1, the other end of the evaporator 3 and the base 1 are connected through the first fastener, so that the installation efficiency of the evaporator 3 on the base 1 is high, and the installation strength is high.
[0031] Specifically, after the installation of the evaporator 3 on the base 1 is completed, the lower end of the evaporator 3 abuts or is adjacent to the first surface 11, and the upper end of the evaporator 3 abuts or is adjacent to the front panel 2.
[0032] In some embodiments, the base 1 includes a first mounting plate at one end in the length direction, and is provided with a motor cover at the other end in the length direction, and the evaporator 3 is located between the first mounting plate and the motor cover, wherein the side of the first mounting plate facing the evaporator 3 is provided with a positioning column, the side of the evaporator 3 facing the first mounting plate is provided with a positioning hole, the positioning column is fitted in the positioning hole, and the first fastener includes a threaded member connecting the evaporator 3 and the motor cover.
[0033] By arranging the positioning hole on the end surface of the evaporator 3, the structure of the evaporator 3 is simple and the manufacturing cost is low. By connecting the evaporator 3 and the base 1 through the threaded member, the evaporator 3 is convenient to disassemble and assemble on the base 1. In combination with the design of the inclined plate of the evaporator 3, the overall structural strength of the evaporator 3 can be increased to a certain extent, so that the evaporator 3 is less likely to be damaged such as deformation when facing vibration and other conditions during operation of the air conditioner, and the service life of the evaporator 3 is high.
[0034] Specifically, the positioning hole is at least two, the end plate of the evaporator 3 away from the positioning hole is provided with a first mounting hole, the motor cover is provided with a second mounting hole, and the threaded member can include a bolt and a nut, the bolt passes through the second mounting hole and the first mounting hole and is threadedly connected with the nut.
[0035] In some embodiments, the water pan 4 is connected to the base 1 through the second fastener at opposite ends in the length direction of the base 1. The water pan 4 is convenient and reliable to install on the base 1.
[0036] Specifically, the length of the water groove on the water pan 4 is greater than or equal to the length of the evaporator 3, the second fastener can be a bolt, the end surface of the water pan 4 is provided with a threaded hole, and the bolt passes through the base 1 and is threadedly connected with the threaded hole.
[0037] In some embodiments, the water pan 4 is clamped with the base 1. Thus, the positioning effect of the water pan 4 on the base 1 is good, and the installation efficiency of the water pan 4 on the base 1 is effectively improved.
[0038] In some embodiments, the water pan 4 abuts against the first surface 11. At this time, the water pan 4 can collect the condensed water on the first surface 11, effectively avoiding that the condensed water on the first surface 11 drips from the air inlet 6 to the outside to affect the user experience.
[0039] At this time, the side of the water pan 4 facing the first surface 11 is provided with a buckle, and the first surface 11 is provided with a clamping hole, and the buckle is clamped in the clamping hole.
[0040] And / or, the mounting cavity 5 further includes a second surface 12 arranged on the base 1, the second surface 12 is connected with the lower edge of the first surface 11, and the water pan 4 abuts against the second surface 12.
[0041] Thus, the water pan 4 is reliably mounted on the base 1, and the water pan 4 further avoids affecting the air inlet area, further reduces the load of the fan, and the energy efficiency ratio of the air conditioner is higher.
[0042] In some embodiments, in a projection plane perpendicular to the length direction of the base 1, an angle between an extension direction of the projection of the evaporator 3 and the width direction of the base 1 is a, where 45°≤a≤75°.
[0043] The evaporator 3 at this angle can better guide and comb the airflow passing through, so that the airflow can flow more uniformly through the surface of the evaporator 3, and ensure that all parts of the evaporator 3 can fully participate in heat exchange, and better avoid local uneven heat exchange.
[0044] Specifically, a can be 45°, 60°, and 75°.
[0045] In some embodiments, the air inlet 6 is arranged on the bottom surface of the base 1, and the width of the part of the bottom surface of the base 1 located on the side away from the front panel 2 of the air inlet 6 is P, and the width of the bottom surface of the water pan 4 is Z, where P / 3≤Z≤2P / 5.
[0046] This arrangement effectively avoids the water pan 4 being too wide and occupying the original reasonable installation and operation space of the components in the base 1, and avoids mutual extrusion and collision of the components to affect the normal operation of the air conditioner.
[0047] Specifically, the width of the water pan 4 gradually increases from bottom to top, and the minimum width Z of the water pan 4 can be 1 / 3, 11 / 30, and 2 / 5 of P.
[0048] In some embodiments, the distance between the bottom surface and the top surface of the water pan 4 is m, where 10mm≤m≤40mm.
[0049] The internal space of the air conditioner is relatively compact, and the amount of condensed water generated is relatively not too large, so the water pan 4 under the above parameters can effectively complete the collection of the condensed water, and also does not occupy too much internal space, ensuring that the reasonable layout of the components in the air conditioner and air circulation are not affected too much.
[0050] Specifically, the height m of the water pan 4 can be 10mm, 20mm, 30mm, and 40mm.
[0051] In some embodiments, in a projection plane perpendicular to the height direction of the base 1, the projection of the lower edge of the evaporator 3 coincides with the projection of the water pan 4, and the distance between the projection of the lower edge of the evaporator 3 and the projection of the edge adjacent to the front panel 2 of the top surface of the water pan 4 is n, where 4mm≤n≤20mm.
[0052] The setting can ensure that the condensed water on the evaporator 3 can accurately drip into the water pan 4 under the action of gravity when the condensed water flows to the lowest point of the evaporator 3, and can effectively avoid that the water pan 4 excessively occupies the internal space of the air conditioner to affect the air inlet area, and effectively ensure the normal operation and the refrigeration and heating efficiency of the air conditioner.
[0053] Specifically, the front edge of the water receiving groove on the water pan 4 coincides with the front edge of the water pan 4. The distance n between the front edge of the water pan 4 and the lower edge of the evaporator 3 in the front-rear direction can be 4mm, 7mm, 10mm, 13mm, 16mm and 20mm.
