Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a chassis, casing, and outdoor unit of an air conditioner. Background Technology

[0002] With the development and progress of technology, air conditioning has gradually become a necessity in people's lives. An air conditioner generally consists of an indoor unit installed indoors and an outdoor unit installed outdoors.

[0003] Since air conditioner outdoor units need to be installed outdoors, water from the external environment (such as rainwater) can easily seep into their interior. Furthermore, water can easily accumulate inside the outdoor unit during operation. Therefore, a drain hole is usually installed at the bottom of the outdoor unit to drain any accumulated water.

[0004] However, the current method of draining water from the air conditioner's outdoor unit through the drain hole is not very reliable. Utility Model Content

[0005] This application provides a chassis, a housing, and an outdoor air conditioner unit. It solves the problem of poor stability in existing technologies that rely on drain holes to drain water from the interior of the outdoor air conditioner unit. The technical solution is as follows:

[0006] On the one hand, a chassis is provided, including: a floor plate and side plates;

[0007] The side plates are distributed around the base plate and are fixedly connected to the outer edge of the base plate; the base plate and the side plates are used to form a mounting groove;

[0008] The base plate has an overflow hole communicating with the mounting groove, and the inner wall of the overflow hole has multiple notches.

[0009] By providing an overflow hole on the chassis that connects to the mounting slot, water can be promptly drained through the overflow hole when the drain hole on the chassis becomes clogged. Thus, for the outdoor unit, if water accumulates inside, it can be drained not only through the drain hole but also through the overflow hole, effectively improving the stability of water drainage and ensuring high reliability of the outdoor unit. Furthermore, the overflow hole has multiple notches on its inner wall, which disrupt the surface tension of the water, allowing for smoother water drainage and increasing the flow rate of water exiting through the overflow hole, further enhancing the stability of water drainage from the outdoor unit.

[0010] In some possible implementations, the opening of the overflow hole extends along a first direction, and the plurality of notches are distributed in a second direction on at least one side of the overflow hole; wherein the first direction intersects the second direction and is parallel to the base plate.

[0011] In some possible implementations, the plurality of notches are distributed on the same side of the overflow orifice in the second direction, and the plurality of notches are arranged sequentially in the first direction.

[0012] In some possible implementations, the plurality of notches includes at least one first notch and at least one second notch; the at least one first notch and the at least one second notch are distributed on opposite sides of the overflow orifice in the second direction.

[0013] In some possible implementations, the first gap is positioned differently in the first direction than the second gap. That is, the first and second gaps are asymmetrically arranged.

[0014] By setting a first and second notch arranged asymmetrically on the inner wall of the overflow hole, the degree of disruption to the surface tension of the accumulated water can be further increased, thereby further increasing the flow rate of the accumulated water discharged through the overflow hole.

[0015] In some possible implementations, there are multiple first gaps and multiple second gaps; in the first direction, multiple first gaps and multiple second gaps are arranged alternately.

[0016] This ensures that the first gaps distributed on one side of the overflow hole in the second direction are not symmetrically distributed with the second gaps distributed on the other side of the overflow hole in the second direction.

[0017] In some possible implementations, the plurality of first gaps and the plurality of second gaps are centrally symmetrical.

[0018] In some possible implementations, in the first direction, the distance between two adjacent first gaps is equal to the distance between two adjacent second gaps.

[0019] In some possible implementations, the overflow orifice has a first end position and a second end position disposed opposite to each other in the first direction;

[0020] In the first direction, the distance between the first gap closest to the first end position among the plurality of first gaps and the first end position is equal to the distance between the second gap closest to the second end position among the plurality of second gaps and the second end position.

[0021] In some possible implementations, the bottom plate on the side opposite to the side plate also has a plurality of ribs, which are distributed around the outer periphery of the overflow hole;

[0022] Specifically, in the outer peripheral direction of the overflow hole, there is a notch between two adjacent ribs. This notch can be a first notch or a second notch.

[0023] By adding multiple ribs around the overflow hole, the strength of the overflow hole location in the base plate can be increased, ensuring a high overall strength of the chassis. Furthermore, the side of the base plate opposite the side plates is the back of the chassis. Adding multiple ribs to the back of the chassis, rather than the front, enhances chassis strength while ensuring that drainage from the overflow hole is not affected.

[0024] In some possible implementations, the base plate has a plurality of overflow holes arranged in a row in the first direction. By providing multiple overflow holes, the ability to drain accumulated water due to blockage of the drain holes can be enhanced.

[0025] In some possible implementations, the overflow orifice is waist-shaped, elliptical, or elongated.

[0026] In some possible implementations, the base plate also has a drain hole communicating with the mounting groove, the drain hole being separately disposed from the overflow hole.

[0027] In some possible implementations, the bottom of the mounting groove has a first molding surface and a second molding surface; in a third direction perpendicular to the base plate, the distance between the first molding surface and the side of the side plate away from the base plate is less than the distance between the second molding surface and the side of the side plate away from the base plate; wherein the opening of the overflow hole is distributed on the first molding surface, and the opening of the drain hole is distributed on the second molding surface.

[0028] A drain hole is provided on the deeper second molding surface to ensure that internal water is drained out preferentially through the drain hole. An overflow hole is provided on the shallower first molding surface. When the drain pipe is not blocked and the drain hole can drain normally, water will not be discharged through the overflow hole. If the drain hole is blocked, the water needs to overflow the first molding surface before being discharged through the overflow hole, so as to ensure that the water inside the air conditioner outdoor unit can be discharged in time, thereby ensuring that the components inside the air conditioner outdoor unit are not soaked by water.

[0029] In some possible implementations, the bottom of the mounting groove also has a flow channel that communicates with the drain hole;

[0030] In the third direction, the distance between the bottom surface of the flow channel and the side of the side plate away from the bottom plate is greater than the distance between the first molding surface and the side plate away from the bottom plate, and less than or equal to the distance between the second molding surface and the side plate away from the bottom plate.

[0031] In this way, the water introduced through the flow channel can preferentially flow to the second molding surface and be discharged through the drain holes on the second molding surface. Furthermore, if the drain holes become blocked, the water in the flow channel will only be discharged through the overflow holes after it has overflowed the first molding surface.

[0032] On the other hand, a housing is provided, comprising: a housing shell, and a chassis connected to the bottom of the housing shell, the chassis being the chassis described above.

[0033] In another aspect, an air conditioner outdoor unit is provided, characterized in that it includes: the aforementioned outer casing, and an air conditioner outdoor unit body installed inside the outer casing. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0045] This application provides a chassis that can be installed at the bottom of an air conditioner outdoor unit. Of course, the chassis can also be installed at the bottom of other equipment requiring drainage; this application does not limit this. Please refer to... Figure 1 , Figure 1 This is a schematic diagram of the structure of a chassis provided in an embodiment of this application. The chassis 000 may include: a base plate 100 and a side plate 200.

[0046] Side plates 200 in the chassis 000 are distributed around the base plate 100, and the side plates 200 can be fixedly connected to the outer edge of the base plate 100. Here, the base plate 100 and the side plates 200 are used to form a mounting groove U. That is, the chassis 000 can have a mounting groove U on one side in the thickness direction. The mounting groove U of the chassis 000 is used to connect with the bottom of the outer casing of the air conditioner outdoor unit. Here, the bottom of the outer casing has an opening, and the bottom of the outer casing can be installed in the mounting groove U of the chassis 000, so that the chassis 000 can seal the bottom opening of the outer casing, thereby allowing the outer casing and the chassis 000 to form a closed cavity, which can support the various components in the air conditioner outdoor unit.

[0047] The base plate 100 in the chassis 000 may have an overflow hole V1 communicating with the mounting groove U. It should be noted that the base plate 100 may also have a drain hole V2 communicating with the mounting groove U. This drain hole V2 is separate from the overflow hole V1. That is, the drain hole V2 and the overflow hole V1 are not directly connected.

[0048] In this application, when water accumulates inside the outdoor unit of the air conditioner, it can be drained preferentially through the drain hole V2 in the chassis 000. However, if the drain hole V2 becomes blocked, the water may not be able to drain out in a timely manner. In this case, the water can be drained through the overflow hole V1 in the chassis 000. Therefore, an additional overflow hole V1 is provided on the chassis 000 to allow water to drain out promptly when the drain hole V2 becomes blocked. This effectively improves the stability of draining water from inside the outdoor unit of the air conditioner, ensuring higher reliability of the outdoor unit.

[0049] In this application, the inner wall of the overflow hole V1 has multiple notches P. By providing multiple notches P on the inner wall of the overflow hole V1, the surface tension of the accumulated water can be disrupted, allowing the overflow hole V1 to discharge the accumulated water more smoothly. This increases the flow rate of the water discharged through the overflow hole V1, further improving the stability of draining the accumulated water from inside the air conditioner outdoor unit.

[0050] In summary, by providing an overflow hole on the chassis that communicates with the mounting slot, water can be promptly drained through the overflow hole when the drain hole on the chassis becomes clogged. Thus, for the outdoor unit of the air conditioner, when water accumulates inside, it can be drained not only through the drain hole but also through the overflow hole, effectively improving the stability of water drainage and ensuring high reliability of the outdoor unit. Furthermore, the overflow hole has multiple notches on its inner wall, which disrupt the surface tension of the water, allowing for smoother water drainage and increasing the flow rate of water exiting through the overflow hole, further enhancing the stability of water drainage from the outdoor unit.

[0051] In one possible implementation, such as Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of another chassis structure provided in an embodiment of this application. Figure 3 yes Figure 2 The diagram shows a partial enlarged view of the chassis at point A. The opening of the overflow orifice V1 can extend along the first direction X. That is, the length of the opening of the overflow orifice V1 in the first direction X is larger, while the width of the opening of the overflow orifice V1 in the second direction Y is smaller. Exemplarily, the overflow orifice V1 can be waist-shaped, elliptical, or elongated. Of course, the overflow orifice V1 can also be in other shapes. This application does not limit this.

[0052] Here, the first direction X intersects the second direction Y; for example, the first direction X and the second direction Y can be perpendicular. Furthermore, both the first direction X and the second direction Y are parallel to the base plate 100.

[0053] In this case, by setting a larger length for the overflow hole V1 in the first direction X, the flow rate of the overflow hole V1 when draining accumulated water can be guaranteed. In addition, by setting a smaller width for the overflow hole V1 in the second direction Y, external debris (such as branches or small stones) can be effectively prevented from penetrating into the interior of the air conditioner outdoor unit through the overflow hole V1, so as to ensure that the internal components of the air conditioner outdoor unit are not damaged.

[0054] In this application, the plurality of notches P provided on the inner wall of the overflow hole V1 can be distributed in the second direction Y on at least one side of the overflow hole V1. Here, the plurality of notches P can be distributed in the second direction Y on the same side of the overflow hole V1, or they can be distributed in the second direction Y on two opposite sides of the overflow hole V1. The embodiments of this application do not limit this.

[0055] In some embodiments, such as Figure 4 As shown, Figure 4 This is a partially enlarged view of another overflow hole provided in an embodiment of this application. Multiple notches P are provided on the inner wall of the overflow hole V1, and these notches P are all distributed on the same side of the overflow hole V1 in the second direction Y. That is, among the two opposite sides of the overflow hole V1 in the second direction Y, multiple notches P are distributed on one side of the overflow hole V1, while no notches P are distributed on the other side of the overflow hole V1.

[0056] Here, the multiple notches P distributed on the same side of the overflow orifice V1 can be arranged sequentially in the first direction X. For example, when there are three or more notches P distributed on the same side of the overflow orifice V1, the multiple notches P distributed on the same side of the overflow orifice V1 are arranged at equal intervals. That is, in the first direction, the distance between any two adjacent notches P is the same.

[0057] In some embodiments, such as Figure 3 As shown, for the multiple notches P provided on the inner wall of the overflow hole V1, some of the notches P can be distributed on one side of the overflow hole V1 in the second direction Y, and other notches P can be distributed on both sides of the overflow hole V1 in the second direction Y.

[0058] That is, the multiple notches P provided on the inner wall of the overflow hole V1 may include at least one first notch P1 and at least one second notch P2. Here, at least one first notch P1 and at least one second notch P2 may be distributed on opposite sides of the overflow hole V1 in the second direction Y.

[0059] In one possible implementation, the first notch P1 is positioned at the same location as the second notch P2 in the first direction X. That is, at least one first notch P1 and at least one second notch P2 are in one-to-one correspondence, and the corresponding first notch P1 and second notch P2 are symmetrically distributed on both sides of the major axis of the overflow orifice V1. Here, the major axis of the overflow orifice V1 refers to the axis of symmetry of the overflow orifice V1 parallel to the first direction X.

[0060] In another possible implementation, such as Figure 3As shown, the distribution position of the first notch P1 in the first direction X is different from that of the second notch P2 in the first direction X. That is, at least one first notch P1 and at least one second notch P2 are asymmetrically distributed on both sides of the major axis of the overflow orifice V1. Here, the major axis of the overflow orifice V1 refers to the axis of symmetry of the overflow orifice V1 in the first direction X.

[0061] In this application, by setting an asymmetrically arranged first notch P1 and second notch P2 on the inner wall of the overflow hole V1, the degree of disruption of the surface tension of the accumulated water can be further improved, thereby further increasing the flow rate of the accumulated water discharged through the overflow hole.

[0062] In the embodiments of this application, such as Figure 2 As shown, the base plate 100 has multiple overflow holes V1, which can be arranged in a row in the first direction X. By providing multiple overflow holes V1, the ability to drain accumulated water due to blockage of the drain hole V2 can be enhanced.

[0063] like Figure 5 As shown, Figure 5 This is a schematic diagram of another overflow hole structure provided in an embodiment of this application. In the same overflow hole V1, there are multiple first notches P1 and multiple second notches P2 provided on the inner wall of the overflow hole V1. In one possible case, the number of first notches P1 and the number of second notches P2 provided on the inner wall of the same overflow hole V1 are the same.

[0064] For example, in the same overflow hole V1, the number of first notches P1 and second notches P2 can be two, three, four, etc. It should be noted that this application uses the example of two first notches P1 and two notches P2 being provided on the inner wall of the overflow hole V1 for illustrative purposes.

[0065] In some implementations, within the same overflow orifice V1, multiple first notches P1 on the inner wall of the overflow orifice V1 can be arranged in the first direction X, and multiple second notches P2 on the inner wall of the overflow orifice V1 can also be arranged in the first direction X. Here, the multiple first notches P1 are all distributed on one side of the overflow orifice V1 in the second direction Y, and the multiple second notches P2 are all distributed on the other side of the overflow orifice V1 in the second direction Y.

[0066] In the same overflow orifice V1, multiple first notches P1 and multiple second notches P2 are arranged alternately in the first direction X. For example, in the same overflow orifice V1, the multiple first notches P1 and multiple second notches P2 are arranged alternately in the first direction X. That is, for the same overflow orifice V1, in the first direction X, there is a second notch P2 between two adjacent first notches P1, and a first notch P1 between two adjacent second notches P2.

[0067] In this case, it can be ensured that the first gaps P1 distributed on one side of the overflow hole V1 in the second direction Y are not symmetrically distributed with the second gaps P2 distributed on the other side of the overflow hole V1 in the second direction Y. This further enhances the ability of the first gaps P1 and the second gaps P2 to break the surface tension of the accumulated water, thereby further increasing the flow rate of the accumulated water discharged through the overflow hole V1.

[0068] It should be noted that when there are three or more first notches P1 and second notches P2 in the same overflow orifice V1, the multiple first notches P1 in the same overflow orifice V1 can be arranged at equal intervals, that is, the distance between any two adjacent first notches P1 in the first direction X is the same. Similarly, the multiple second notches P2 in the same overflow orifice V1 can also be arranged at equal intervals, that is, the distance between any two adjacent second notches P2 in the first direction X is the same.

[0069] In some possible implementations, such as Figure 5 As shown, in the same overflow orifice V1, multiple first notches P1 and multiple second notches P2 are centrally symmetrical. For example, after rotating 180° around the center point of the overflow orifice V1, the multiple first notches P1 can coincide with the multiple second notches P2.

[0070] For example, in the same overflow hole V1, the distance d1 between two adjacent first notches P1 in the first direction X is equal to the distance d2 between two adjacent second notches P2 in the first direction X.

[0071] Furthermore, for the same overflow hole V1, the overflow hole V1 has a first end position Q1 and a second end position Q2 that are disposed opposite to each other in the first direction X. In the first direction X, the distance d3 between the first notch P1 closest to the first end position Q1 and the first end position Q1 is equal to the distance d4 between the second notch P2 closest to the second end position Q2 and the second end position Q2 among the plurality of second notches P2.

[0072] In this way, it can be ensured that the multiple first notches P1 and multiple second notches P2 in the same overflow hole V1 are centrally symmetrical.

[0073] In the embodiments of this application, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of the back of a chassis provided in an embodiment of this application. The bottom plate 100 of the chassis 000, on the side opposite to the side plate 200, also has multiple ribs 300, which can be distributed around the periphery of the overflow hole V1. Here, by providing multiple ribs 300 on the outer periphery of the overflow hole V1, the strength at the location of the overflow hole V1 in the bottom plate 000 can be improved, thereby ensuring a high overall strength of the chassis 000.

[0074] In addition, the side of the base plate 100 that is away from the side plate 200 is the back of the chassis 000. By setting multiple ribs 300 on the back of the chassis 000 instead of setting ribs 300 on the front of the chassis 000, the drainage of the overflow hole V1 can be guaranteed not to be affected while enhancing the strength of the chassis 000.

[0075] It should be noted that multiple ribs 300 are distributed on the outer periphery of each overflow hole V1 to ensure that the chassis 000 has high strength at the location of each overflow hole V1.

[0076] In some possible implementations, for any overflow hole V1, there is a notch P between two adjacent ribs 300 in the outer peripheral direction of the overflow hole V1. This notch P can be a first notch P1 or a second notch P2. That is, the multiple ribs 300 distributed in the outer peripheral direction of the overflow hole V1 can define multiple first notches P1 and multiple second notches P2.

[0077] In the embodiments of this application, such as Figure 7 and Figure 8 As shown, Figure 7 This is a schematic diagram of the structure of a chassis provided in another embodiment of this application. Figure 8 yes Figure 7The diagram shows a cross-sectional view of the chassis at point B-B'. The bottom of the bearing groove U in the chassis 000 has a first forming surface S1 and a second forming surface S2. In the third direction Z perpendicular to the base plate 100, the distance h1 between the first forming surface S1 and the side plate 200 away from the base plate 100 is less than the distance h2 between the second forming surface S2 and the side plate 200 away from the base plate 100. In the third direction Z, the distance h1 between the first forming surface S1 and the side plate 200 away from the base plate 100 represents the depth of the first forming surface S1 in the bearing groove U of the chassis 000; in the third direction Z, the distance h2 between the second forming surface S2 and the side plate 200 away from the base plate 100 represents the depth of the second forming surface S2 in the bearing groove U of the chassis 000. When h1 is less than h2, the first forming surface S1 is shallower in the bearing groove U of the chassis 000, and the second forming surface S2 is deeper in the bearing groove U of the chassis 000.

[0078] In some possible implementations, the openings of the overflow hole V1 in the chassis 000 can be distributed on the first molding surface S1, and the openings of the drain hole V2 in the chassis 000 can be distributed on the second molding surface S2.

[0079] Here, the outdoor unit of the air conditioner usually needs to have a drain pipe installed at the drain hole V2, and the water accumulated inside the outdoor unit needs to be discharged in a directed manner through the drain pipe. Therefore, a drain hole V2 is installed on the deeper second molding surface S2, ensuring that the internal water is discharged first through the drain hole V2 and then directed out through the drain pipe. An overflow hole V1 is installed on the shallower first molding surface S1. If the drain pipe is not blocked and the drain hole V2 can drain normally, water will generally not be discharged through the overflow hole V1. This achieves directed discharge of water from inside the outdoor unit, preventing water from being discharged indiscriminately.

[0080] Here, because the drain pipe is blocked, the drain hole V2 is blocked. The water needs to first overflow the first forming surface S1 and then be discharged through the overflow hole V1 to ensure that the water inside the air conditioner outdoor unit can be discharged in time, thereby ensuring that the components inside the air conditioner outdoor unit will not be soaked by water.

[0081] In some implementations, the bottom of the bearing groove U in the chassis 000 also has a flow channel L, which can communicate with the drain hole V2. Here, the accumulated water inside can be guided through the flow channel L to the drain hole V2 and discharged through the drain hole V2.

[0082] In the third direction Z, the distance h3 between the bottom surface S3 of the flow channel L and the side plate 200 away from the bottom plate 100 is greater than the distance h1 between the first forming surface S1 and the side plate 200 away from the bottom plate 100, and less than or equal to the distance h2 between the second forming surface S2 and the side plate 100 away from the bottom plate 200.

[0083] In other words, in chassis 000, the depth of the bottom surface S3 of the flow channel L is greater than the depth of the first molding surface S1, and is basically flush with the depth of the second molding surface S2. Thus, water introduced through the flow channel L can preferentially flow to the second molding surface S2 and be discharged through the drain hole V2 on the second molding surface S2. Furthermore, if the drain hole V2 is blocked, water in the flow channel L will only be discharged through the overflow hole V1 after overflowing the first molding surface S1.

[0084] It should be noted that the bottom surface S3 of the flow channel L can be an inclined surface with a certain degree of slope, and the depth of the bottom surface S3 of the flow channel L near the second molding surface S2 can be basically the same as the depth of the second molding surface S2, while the depth at other locations can be slightly less than the depth of the second molding surface S2, but greater than the depth of the first molding surface S1. In this way, the bottom surface S3 of the flow channel L can be inclined in the direction towards the drain hole V2, so as to ensure that the water accumulated in the flow channel L can be better discharged through the drain hole V2.

[0085] In some possible implementations, the base plate 100 and the side panels 200 in the chassis 000 can be formed using a one-piece molding process. For example, they can be formed using injection molding or stamping. This application does not limit this aspect.

[0086] In summary, by providing an overflow hole on the chassis that communicates with the mounting slot, water can be promptly drained through the overflow hole when the drain hole on the chassis becomes clogged. Thus, for the outdoor unit of the air conditioner, when water accumulates inside, it can be drained not only through the drain hole but also through the overflow hole, effectively improving the stability of water drainage and ensuring high reliability of the outdoor unit. Furthermore, the overflow hole has multiple notches on its inner wall, which disrupt the surface tension of the water, allowing for smoother water drainage and increasing the flow rate of water exiting through the overflow hole, further enhancing the stability of water drainage from the outdoor unit.
