[0001] The present disclosure relates to the technical field of air conditioners, and more particularly, to an indoor unit and an air conditioner. Background Art

[0002] In the related art, for the indoor unit of an air conditioner, the current indoor unit generally includes an evaporator and an air intake grille disposed above the evaporator. When the indoor unit is operating in a cooling mode, the evaporator is likely to cause condensed water to appear on the air intake grille, and this condensed water may not fall into the water receiving tray of the indoor unit. As a result, water leakage may occur in the indoor unit. Summary of the Invention

[0003] An object of the present disclosure is to provide an indoor unit that can reduce or even avoid the probability of water leakage.

[0004] To achieve the above object, the present disclosure provides an indoor unit, including an evaporator, an air intake grille, and a water receiving tray. The air intake grille is disposed above the evaporator, and a drainage structure is provided on the air intake grille. The drainage structure is configured to drain the condensed water flowing onto itself into the water receiving tray.

[0005] Optionally, the water receiving tray is disposed below the drainage structure, and the drainage structure is configured to guide the condensed water flowing onto itself to flow downward, wherein the projection of the drainage structure on a horizontal plane is located within the projection of the water receiving tray on the horizontal plane.

[0006] Optionally, the indoor unit includes a filter screen, and the filter screen is disposed above the air intake grille.

[0007] Optionally, the air intake grille includes ribs extending in the front-rear direction, and the drainage structure includes drainage members disposed on the ribs.

[0008] Optionally, the ribs extend obliquely downward in the direction from the rear to the front, and the drainage members are disposed on the front sides of the ribs.

[0009] Optionally, the air intake grille includes a plurality of ribs spaced apart in the left-right direction, and at least one of the drainage members is disposed on each rib.

[0010] Optionally, the drainage member is configured as a drainage strip extending in the up-down direction, and the lower end of the drainage strip extends downward beyond the rib.

[0011] Optionally, the drainage strip extends downward from the bottom end of the rib, and the length of the drainage strip is less than or equal to 60 mm.

[0012] Optionally, the drainage strip has a front side surface, and the distance between the front side surface and the front end of the water receiving tray is less than or equal to 120 mm.

[0013] Optionally, the drainage member includes arc-shaped protrusions provided at the bottom end of the rib, and the number of the arc-shaped protrusions is at least two, and at least two of the arc-shaped protrusions are spaced apart in the front-rear direction.

[0028] The following will describe in detail the specific implementation of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0029] In the present disclosure, unless otherwise stated, the orientation words such as "upper, lower, front, rear, left, right" are based on Figure 1 and Figure 2 the XYZ coordinate system defined in, specifically, the X direction refers to the front-rear direction, and the side pointed by the arrow is the front, and the opposite is the rear, the Y direction refers to the left-right direction, the Z direction refers to the up-down direction, and the side pointed by the arrow is the upper, and the opposite is the lower. In addition, the upper corresponds to the top, and the lower corresponds to the bottom. "Inside and outside" refer to the inside and outside of the self-profile of each component. In addition, when the following description refers to the accompanying drawings, the same reference numerals in different drawings represent the same or similar elements, and the present disclosure will not repeat this.

[0030] According to an exemplary embodiment of the present disclosure, an indoor unit is provided. As shown in Figure 1 and Figure 2 , the indoor unit includes an evaporator 1, an air intake grille 2, and a water receiving tray 3. The air intake grille 2 is arranged above the evaporator 1, and a drainage structure 4 is arranged on the air intake grille 2. The drainage structure 4 is used to drain the condensed water flowing to itself into the water receiving tray 3.

[0031] Through the above technical solution, in the indoor unit provided by the present disclosure, when the indoor unit performs refrigeration work, since the air intake grille 2 is arranged above the evaporator 1 and is relatively close to the evaporator 1, therefore, the evaporator 1 easily causes condensed water to appear on the air intake grille 2. When the condensed water on the air intake grille 2 flows to the drainage structure 4, the drainage structure 4 can drain the condensed water flowing to itself into the water receiving tray 3. In this way, it is possible to prevent this condensed water from flowing out of the indoor unit and causing a water leakage phenomenon, that is, the indoor unit of the present disclosure can reduce or even avoid the probability of its own water leakage phenomenon.

[0032] It should be noted that, in the actual installation environment of the indoor unit, there is usually a gap between the upper side of the indoor unit close to the wall and the wall due to the influence of gravity and the installation process, resulting in the intake grille being slightly inclined during actual use. As a result, the condensed water on the intake grille 2 may drip outside the water receiving tray 3, causing a water leakage phenomenon. Therefore, through the above-mentioned drainage structure 4, the probability of water leakage in the indoor unit can be effectively reduced. In addition, the specific structure of the drainage structure 4 is not limited in the present disclosure, and the present disclosure will be introduced in detail in the following embodiments.

[0033] It should also be noted that the "condensed water flowing to the drainage structure 4" includes the condensed water flowing from the intake grille 2 to the drainage structure 4 and the condensed water that can flow on the drainage structure 4 and condenses on the drainage structure 4, which will not be elaborated in the present disclosure.

[0034] In an exemplary embodiment of the present disclosure, referring to Figure 2 as shown in, the water receiving tray 3 can be arranged below the drainage structure 4, and the drainage structure 4 is used to guide the condensed water flowing to itself to flow downward, wherein the projection of the drainage structure 4 on the horizontal plane is located within the projection of the water receiving tray 3 on the horizontal plane. In this way, the condensed water dripping from the drainage structure 4 can all fall into the water receiving tray 3, effectively reducing the probability of water leakage in the indoor unit.

[0035] In an exemplary embodiment of the present disclosure, referring to Figure 2 as shown in, the indoor unit includes a filter screen 5, and the filter screen 5 is arranged above the intake grille 2. Here, in the way that the layout space remains basically unchanged, compared with the way of arranging the filter screen 5 below the intake grille 2, arranging the filter screen 5 above the intake grille 2 can make the intake grille 2 closer to the evaporator 1. As a result, the intake grille 2 is more likely to have condensed water. In this way, the effect of preventing water leakage in the indoor unit by using the above-mentioned drainage structure 4 will be more obvious. Therefore, when the drainage structure 4 is applied to the indoor unit with the filter screen 5 arranged above the intake grille 2, the water leakage prevention effect of the indoor unit will be better, improving the use experience of such indoor units.

[0036] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 as shown in, the intake grille 2 includes ribs 21 extending in the front-rear direction, and the drainage structure 4 can include drainage members 41 arranged on the ribs 21. Here, when the indoor unit is performing refrigeration work, the ribs 21 of the intake grille 2 are prone to have condensed water. Therefore, arranging the drainage members 41 on the ribs 21 is conducive to draining the condensed water on the ribs 21 into the water receiving tray 3.

[0037] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2As shown in the figure, the rib 21 can extend obliquely downward in the front-to-back direction, and the drainage member 41 is arranged on the front side of the rib 21. Here, by arranging the rib 21 to be inclined forward and downward, the condensed water on the rib 21 can flow to the drainage member 41, so that the condensed water on the rib 21 falls into the water receiving tray 3 through the drainage member 41, ensuring that all the condensed water on the rib 21 falls into the water receiving tray 3 and preventing water leakage in the indoor unit.

[0038] It should be noted that during the actual installation of the indoor unit, there may usually be a gap between the upper part close to the wall side of the indoor unit itself and the wall due to gravity and the influence of the installation process. Therefore, the rib 21 may be slightly inclined forward and downward. Here, without the drainage structure 4, the condensed water on the rib 21 will gradually flow forward to the front side of the rib 21 and be located outside the water receiving tray 3, resulting in the condensed water dripping outside the water receiving tray 3 and causing water leakage. Therefore, by setting the drainage structure 4 in the present disclosure, water leakage in the indoor unit can be effectively prevented. In addition, when the rib 21 is slightly inclined forward and downward due to installation reasons 1, the rib 21 can also accelerate the flow of the condensed water to the drainage member 41, facilitating the condensed water to drip into the water receiving tray 3.

[0039] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 As shown in the figure, the intake grille 2 may include a plurality of ribs 21 arranged at intervals in the left-right direction, and at least one drainage member 41 is provided on each rib 21. In this way, the condensed water on each rib 21 can fall into the water receiving tray 3 through the drainage member 41 thereon. Here, according to some embodiments, a plurality of drainage members 41 may be provided on each rib 21, and the present disclosure does not limit this. Of course, in some other embodiments of the present disclosure, drainage members 41 may also be provided on some ribs 21 of the intake grille 2, and the present disclosure can make adaptive designs according to needs.

[0040] It should be noted that the drainage member 41 of the present disclosure may be integrally formed with the corresponding rib 21, or may be detachably or fixedly connected to the rib 21, that is, the present disclosure does not limit the specific connection manner between the drainage member 41 and the rib 21.

[0041] In the exemplary embodiment of the present disclosure, the drainage member 41 can be constructed in any suitable manner. Optionally, referring to Figures 1 to 3As shown, the drainage member 41 can be configured as a drainage strip extending in the vertical direction, and the lower end of the drainage strip extends downward beyond the rib 21. In this way, the drainage strip can guide the condensed water flowing to itself to flow downward, so that the condensed water drips from the lower end of the drainage strip into the water receiving tray 3. Here, according to some embodiments, the drainage strip can be configured in a rectangular shape or a trapezoidal shape, and the specific shape of the drainage strip in the present disclosure is not limited. In addition, according to other embodiments, the drainage strip can extend obliquely in the vertical direction, and the present disclosure also does not limit this.

[0042] Optionally, in the embodiment where the drainage member 41 is configured as a drainage strip, referring to Figure 2 and Figure 3 as shown, the drainage strip can extend downward from the bottom end of the rib 21, and the length of the drainage strip is less than or equal to 60 mm. Here, referring to Figure 2 as shown, Figure 2 H in represents the length of the drainage strip, and the value of H is less than or equal to 60 mm. For example, the value of H can be 50 mm.

[0043] Optionally, referring to Figure 2 and Figure 3 as shown, the drainage strip has a front side 411, and the distance between the front side 411 and the front end of the water receiving tray 3 is less than or equal to 120 mm. In this way, it can ensure that the condensed water on the drainage strip can fall into the water receiving tray 3, and can also make full use of the layout space inside the indoor unit, avoiding the distance between the front side 411 and the front end of the water receiving tray 3 being too large and affecting the layout of the internal components of the indoor unit. Here, referring to Figure 2 as shown, Figure 2 L in represents the distance between the front side 411 and the front end of the water receiving tray 3, and the value of L is less than or equal to 120 mm. For example, the value of L can be 80 mm or 10 mm.

[0044] Optionally, referring to Figure 4 as shown, the drainage member 41 can include an arc-shaped protrusion 412 provided at the bottom end of the rib 21, and the number of the arc-shaped protrusions 412 is at least two, and at least two arc-shaped protrusions 412 are arranged at intervals in the front-rear direction. In this way, the condensed water flowing to the arc-shaped protrusion 412 can gradually flow to the bottom end of the arc-shaped protrusion 412, and then drip into the water receiving tray 3.

[0045] Optionally, referring to Figure 5 as shown, the drainage member 41 can be configured as a wavy protrusion provided at the bottom end of the rib 21. In this way, the condensed water flowing to the wavy protrusion can gradually flow to the bottom end of the wavy protrusion, and then drip into the water receiving tray 3.

[0046] The above introduced three embodiments of the drainage member 41 in the case where the drainage structure 4 includes the drainage member 41. However, the drainage member 41 of the present disclosure is not limited to the above embodiments, and the present disclosure can be adaptively designed according to actual needs. Of course, in another embodiment of the drainage structure 4, the drainage structure 4 can be configured as a part of the rib 21. For example, referring to Figure 6 as shown, the rib 21 can have a V-shaped bottom surface, and the drainage structure 4 can be configured as the bottom angle of the V-shaped bottom surface. At this time, the condensed water on the rib 21 can gradually gather at the bottom angle and then drip into the water receiving tray 3. In this way, the drainage function of the drainage structure 4 can also be realized.

[0047] In some embodiments of the present disclosure, referring to Figure 2 as shown, the intake grille 2 includes ribs 21 extending in the front-rear direction, and the drainage structure 4 includes a drainage member 41 provided on the rib 21. Among them, the distance between the top end of the evaporator 1 and the bottom end of the rib 21 is less than or equal to 12 mm. Here, in the case where the distance between the top end of the evaporator 1 and the bottom end of the rib 21 is less than or equal to 12 mm, condensed water is more likely to appear on the rib 21. At this time, by providing the drainage structure 4, the anti-leakage effect of the indoor unit can be made more obvious. Here, the distance between the top end of the evaporator 1 and the bottom end of the rib 21 can be 10 mm, and the present disclosure does not limit this.

[0048] In addition, referring to Figure 1 and Figure 2 as shown, the indoor unit may include a middle frame 100, and the intake grille 2 may be provided on the middle frame 100. The present disclosure does not limit this.

[0049] Next, the present disclosure will take the drainage member 41 being configured as a drainage strip as an example to introduce the anti-leakage process of the indoor unit in detail. First, when the indoor unit is performing refrigeration work, condensed water will appear on the part of the rib 21 corresponding to the top end of the evaporator 1. These condensed water will flow forward along the rib 21. When it flows to the drainage strip, it will flow downward along the drainage strip and finally drip into the water receiving tray 3. In this way, the leakage of the indoor unit can be effectively prevented.

[0050] According to the second aspect of the present disclosure, an air conditioner is provided, including the indoor unit as described above. This air conditioner has all the beneficial effects of the above indoor unit, and the present disclosure will not elaborate here.

[0051] The above has described the preferred embodiments of the present disclosure in detail with reference to the drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0052] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable way without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0053] In addition, any combination can also be made among various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
