Description

[0002] An air conditioner generally includes an indoor unit and an outdoor unit. As the name implies, the indoor unit is installed indoors, and the outdoor unit is installed outdoors. During daily use, since the air outlet of the outdoor unit is exposed, rainwater is likely to enter the interior of the outdoor unit through the air outlet. To timely drain the rainwater entering the interior of the outdoor unit, a drainage structure is usually provided on the chassis of the outdoor unit. The existing drainage structure on the chassis is usually a drainage hole.

[0003] Most of the existing chassis of air conditioner outdoor units are provided with multiple drainage holes, the purpose of which is to smoothly drain the condensed water generated by the condenser from the chassis and prevent water accumulation and icing on the chassis in a low-temperature and high-humidity environment. Especially when ice forms at the bottom of the condenser, it will lead to poor heat exchange effect at the bottom and even the possibility of freezing the heat exchange copper pipe. However, in the process of user use, the multi-drainage-hole outdoor unit chassis is likely to cause condensed water to flow out from different drainage holes, unable to drain water centrally, affecting the aesthetics of the user's use environment. At the same time, if the position of the drainage hole or the forming design of the chassis is improper, dead water areas will still appear on the chassis, which is likely to cause partial corrosion of the chassis, and then the impact resistance of the chassis structure becomes poor, the chassis is prone to deformation, and moreover, the setting of multiple drainage holes is likely to reduce the structural strength of the chassis.

[0056] The split air conditioner includes an indoor unit and an outdoor unit. Generally, the indoor unit includes components such as an evaporator, a blower, an air filter, a heater, etc. The outdoor unit mainly includes components such as a housing, a compressor, a condenser, and a bottom plate. Among them, the chassis of the outdoor unit is the foundation of the entire outdoor unit, and the chassis directly bears the weight of the housing, the compressor, and the condenser. At the same time, since the air outlet of the outdoor unit is exposed during daily use, rainwater is likely to enter the interior of the outdoor unit through the air outlet. Therefore, in order to drain the rainwater entering the interior of the outdoor unit in time, a drainage structure is usually provided on the chassis, and the drainage structure on the existing chassis is usually a drainage hole.

[0057] Most existing air conditioner outdoor unit chassis are provided with multiple drainage holes, the purpose of which is to smoothly drain the condensed water generated by the condenser from the chassis, preventing water accumulation and icing on the chassis in a low-temperature and high-humidity environment. Especially when ice forms at the bottom of the condenser, it will lead to poor heat exchange effect at the bottom and even the possibility of freezing the heat exchange copper pipe. However, during the user's use of the outdoor unit chassis with multiple drainage holes, it is easy for the condensed water to flow out from different drainage holes, unable to drain centrally, affecting the beauty of the user's use environment. At the same time, if the position of the drainage hole or the forming design of the chassis is improper, dead water areas will still appear on the chassis, easily causing partial rust of the chassis, and then making the impact resistance of the chassis structure worse, the chassis is prone to deformation. Moreover, the setting of multiple drainage holes is likely to reduce the structural strength of the chassis.

[0058] As Figures 1 - 10 shown, the present invention proposes a bottom plate 111, which is arranged at the bottom of the outdoor unit 1 to solve the problems of poor drainage concentration and easy appearance of dead water areas existing in the existing chassis.

[0059] In the overall design, the bottom plate 111 includes a bottom plate body 1101 and a frame 1113. Among them, the bottom plate body 1101 is in a flat plate shape, and drainage holes 1115 are arranged on the bottom plate body 1101. The upper surface of the bottom plate body 1101 is set as a diversion inclined surface 1102, and the diversion inclined surface 1102 inclines from both sides in the length direction of the bottom plate body 1101 towards the direction of the drainage hole 1115, and also inclines from both sides in the width direction of the bottom plate body 1101 towards the direction of the drainage hole 1115.

[0060] Further, the frame 1113 extends along the circumferential direction of the bottom plate body 1101, and the frame 1113 is used to connect with the side plate of the outdoor unit 1. A reinforcing rib 1111 is arranged at the connection between the frame 1113 and the bottom plate body 1101. The reinforcing rib 1111 extends along the circumferential direction of the bottom plate body 1101, and the reinforcing rib 1111 has a guiding surface communicating with the diversion inclined surface 1102.

[0061] Specifically, by arranging the diversion inclined surface 1102 on the bottom plate body 1101, the condensed water accumulated in the outdoor unit 1 can be quickly drained through a drainage hole 1115, thereby ensuring the timely and effective collection and drainage of the condensed water falling on the outdoor unit 1, helping to eliminate the dead water area, preventing the chassis from rusting due to water accumulation. At the same time, by arranging the reinforcing rib at the connection between the bottom plate body and the frame, on the one hand, it helps to improve the structural strength of the bottom plate and extend the service life of the bottom plate 111 in cooperation with the structure of the bottom plate body 1101; on the other hand, it can make the guiding surface of the reinforcing rib 1111 cooperate with the diversion inclined surface 1102, thereby further enhancing the drainage effect of the bottom plate 111 and improving the drainage concentration of the bottom plate 111.

[0062] It should be understood that, as Figure 1As shown, the outdoor unit 1 includes a cabinet 10. Among them, a partition (not shown in the figure) is provided inside the cabinet 10, and the partition divides the internal space of the cabinet 10 into a first cavity (not shown in the figure) and a second cavity (not shown in the figure). A compressor and a four-way valve assembly are installed inside the first cavity. A blower and a heat exchanger are provided in the second cavity. Combined with Figure 2 and Figure 3 As shown, in this embodiment, a chassis assembly 11 is provided at the bottom of the cabinet 10, and the chassis assembly 11 includes a bottom plate 111 and feet 112. Among them, a compressor is installed on the bottom plate 111, the blower is installed on the bottom plate 111 through a motor bracket, and the bottom plate 111 is connected to the bottom of the heat exchanger so that the bottom plate 111 can support the heat exchanger.

[0063] In this embodiment, the bottom plate 111 includes a bottom plate body 1101, and the bottom plate body 1101 is a rectangular plate-like structure. A drain hole 1115 is provided on the bottom plate body 1101. It can be understood that the drain hole 1115 can be provided at the center position of the bottom plate body 1101, or the drain hole 1115 can be provided on one side of the bottom plate body 1101. Optionally, along the length direction of the bottom plate body 1101, the drain hole 1115 is provided close to one side of the bottom plate body 1101, and along the width direction of the bottom plate body 1101, the drain hole 1115 is provided close to one side of the bottom plate body 1101. At the same time, the upper surface of the bottom plate body 1101 is provided as a diversion inclined surface 1102, and the diversion inclined surface 1102 inclines from both sides in the length direction of the bottom plate body 1101 towards the drain hole 1115 direction, and inclines from both sides in the length direction of the bottom plate body 1101 towards the drain hole 1115 direction. At this time, the liquid falling on the bottom plate body 1101 will flow from the four peripheral edges of the bottom plate body 1101 towards the drain hole 1115.

[0064] Furthermore, a plurality of confluence grooves 1114 are provided on the upper surface of the bottom plate body 1101, and the confluence grooves 1114 communicate with each other. The drain hole 1115 is located at the lowest point of the plurality of confluence grooves 1114, and the bottom walls of all the confluence grooves 1114 jointly define at least part of the diversion inclined surface 1102.

[0065] Specifically, the arrangement of the confluence grooves 1114 helps to enhance the structural strength of the bottom plate body 1101, and the plurality of confluence grooves 1114 are connected, which can effectively ensure the timely collection and discharge of the condensed water falling on the outdoor unit 1, thereby avoiding the formation of an "island" structure, helping to eliminate dead water areas, preventing the chassis from rusting due to water accumulation, and extending the service life of the bottom plate body 1101.

[0066] It needs to be further understood that as Figures 2 - 6As shown, a plurality of collecting grooves 1114 are provided on the upper surface of the bottom plate body 1101, and the drain hole 1115 is located at the bottom wall of the collecting groove 1114 with the maximum depth, that is, the lowest point of the bottom plate body 1101. Optionally, the upper surface of the bottom plate body 1101 has a plurality of recessed structures to form the collecting grooves 1114, and each part of each collecting groove 1114 has the same recessed depth, so that the bottom wall of the collecting groove 1114 is still an inclined surface. The depths of the collecting grooves 1114 are different and communicate with each other. Cooperating with the guiding inclined surface of the bottom plate body 1101 helps to ensure that the condensed water falling on the outdoor unit 1 can be quickly collected and discharged. At the same time, the plurality of collecting grooves 1114 with different depths helps to improve the structural strength of the bottom plate 111, thereby avoiding the problem of deformation due to insufficient strength.

[0067] Furthermore, a plurality of protrusions 1112 are provided on the upper surface of the bottom plate body 1101, and the heights of the protrusions 1112 are different. The plurality of protrusions 1112 respectively correspond to the heat exchanger, the compressor and the motor bracket of the outdoor unit 1.

[0068] Specifically, by providing a plurality of protrusions 1112 and cooperating with a plurality of collecting grooves 1114, it helps to further improve the structural strength of the bottom plate 111. At the same time, the provision of the protrusions 1112 can be used to install the heat exchanger, the compressor and the motor bracket, which helps to prevent the condensed water entering the outdoor unit 1 from staying or contacting the heat exchanger, the compressor and the motor bracket, thereby reducing the corrosion of the heat exchanger, the compressor and the motor bracket.

[0069] It should be understood that in this embodiment, a plurality of protrusions 1112 are also provided on the upper surface of the bottom plate body 1101. Some of the plurality of protrusions 1112 are arranged at intervals with the collecting grooves 1114, and the other part of the plurality of protrusions 1112 is arranged adjacent to the collecting grooves 1114 or arranged inside the collecting grooves 1114. Optionally, the protrusion 1112 includes a top surface and a side surface. The side surface is connected to the top surface and extends around the edge of the top surface. Among them, the heights of the protrusions 1112 are different, and the top surfaces of the protrusions 1112 are respectively used to connect with the heat exchanger, the compressor and the motor bracket. The side surface of the protrusion 1112 adjacent to the collecting groove 1114 can form the side wall of the collecting groove 1114. By providing the collecting grooves 1114 and the protrusions 1112 with different depths, it helps to improve the structural strength of the bottom plate 111, thereby avoiding the problem of deformation due to insufficient strength. At the same time, it also helps to avoid forming an "island" structure, helps to eliminate the dead water area, prevents the chassis from rusting due to water accumulation, and extends the service life of the bottom plate body 1101.

[0070] It should be noted that in this embodiment, the multiple protrusions 1112 respectively correspond to the heat exchanger, the compressor and the motor bracket of the outdoor unit 1. Among them, the multiple protrusions 1112 for installing the compressor are arranged at the bottom of the first cavity, and the protrusions 1112 connected to the motor bracket are arranged at the bottom of the second cavity. At the same time, the multiple protrusions 1112 connected to the heat exchanger are arranged at intervals along the circumference of the bottom plate body 1101 and are adapted to the shape of the heat exchanger.

[0071] In addition, in this embodiment, the drain hole 1115 is located at the bottom of the second cavity and is arranged at the rear side of the protrusion 1112 connected to the motor bracket. At this time, the arrangement of the drain hole 1115 does not affect the installation of the motor bracket. Among them, the front side of the outdoor unit 1 refers to the side of the outdoor unit 1 with a wind guide cover, and the rear side of the outdoor unit 1 refers to the side of the outdoor unit 1 with a heat exchanger. When the bottom plate body 1101 is arranged on the box body 10, the drain hole 1115 is located between the heat exchanger and the fan.

[0072] In some embodiments of the present application, along the length direction of the bottom plate body 1101, there is a first angle α between the diversion inclined plane 1102 and the horizontal plane, where 1° < α ≤ 8°. At the same time, along the length direction of the bottom plate body 1101, there is a first angle β between the diversion inclined plane 1102 and the horizontal plane, where 1° < β ≤ 8°. By limiting the angle between the diversion inclined plane 1102 and the horizontal plane, it can effectively ensure that after the outdoor unit 1 is installed, the upper surface of the bottom plate body 1101 can divert the condensed liquid, and can cooperate with the settings of the protrusions 1112 and the confluence groove 1114 to effectively separate the installation of the heat exchanger, the compressor and the motor bracket from the diversion of the condensed water.

[0073] It should be noted that if the drain hole 1115 is arranged at the central position of the bottom plate body 1101, the angles between the diversion inclined planes 1102 on both sides of the drain hole 1115 and the horizontal plane are the same. If the drain hole 1115 is arranged close to one side or the edges of the adjacent two sides of the bottom plate body 1101, the angles between the diversion inclined planes 1102 on both sides of the drain hole 1115 and the horizontal plane are different.

[0074] In addition, the bottom plate body 1101 is a sheet metal part and is made by stamping. After stamping, the thickness of each part of the bottom plate body 1101 is the same.

[0075] It should be further understood that, in this embodiment, along the length direction of the bottom plate body 1101, the diversion inclined surface 1102 includes a first diversion inclined surface 11021, a second diversion inclined surface 11022, a third diversion inclined surface 11023, and a fourth diversion inclined surface 11024 arranged in sequence. Among them, the inclination angles of the first diversion inclined surface 11021, the second diversion inclined surface 11022, the third diversion inclined surface 11023, and the fourth diversion inclined surface 11024 are different. Among them, the inclination angles of the second diversion inclined surface 11022 and the third diversion inclined surface 11023 are larger, and a drain hole 1115 is provided at the intersection of the second diversion inclined surface 11022 and the third diversion inclined surface 11023. Such a setting helps to ensure the effect of condensate collection and discharge.

[0076] As Figure 2 and Figure 3 shown, the protrusion 1112 includes a first protrusion 11121, a second protrusion 11122, and a third protrusion 11123. Among them, the position of the first protrusion 11121 is adapted to the position of the motor bracket. In this embodiment, an installation structure is provided on the first protrusion 11121 for cooperating and connecting with the motor bracket. Optionally, along the width direction of the bottom plate body 1101, the first protrusion 11121 is arranged at the center position of the bottom plate body 1101. Along the length direction of the bottom plate body 1101, the first protrusion 11121 is arranged close to one side of the bottom plate body 1101, and the motor bracket is located at the center of the second cavity.

[0077] In this embodiment, along the length direction of the bottom plate body 1101, the second protrusion 11122 is arranged on one side of the first protrusion 11121. At the same time, the number of the second protrusions 11122 is three, and the positions of the three second protrusions 11122 are arranged in a triangular structure and are adapted to the position of the compressor. Optionally, an installation hole is provided on the second protrusion 11122, and the installation hole can be connected to the compressor through a screw member.

[0078] Still as Figure 2 and Figure 3 shown, the number of the third protrusions 11123 is multiple, and the multiple third protrusions 11123 are arranged at intervals along the circumferential direction of the bottom plate body 1101 and are adapted to the shape of the heat exchanger. The number of the third protrusions 11123 is five, among which three third protrusions 11123 are arranged at intervals along the length direction of the bottom plate body 1101, and the other two third protrusions 11123 are arranged at intervals along the width direction of the bottom plate body 1101. Optionally, the multiple third protrusions 11123 are in contact with the bottom of the heat exchanger to be able to support the heat exchanger. A connection structure can be provided on the third protrusion 11123 to be able to connect and fix with the bottom of the heat exchanger. Of course, the heat exchanger can also be connected to the side plate of the box body 10.

[0079] It should be noted that the protruding height of the second protrusion 11122 is the same as or different from that of the first protrusion 11121. In this embodiment, the protruding heights of the second protrusion 11122 and the first protrusion 11121 are the same. Among them, the protruding heights of the multiple third protrusions 11123 are the same and less than the height of the second protrusion 11122.

[0080] Furthermore, the multiple flow collecting grooves 1114 include a first flow collecting groove 11141 and a second flow collecting groove 11142 communicated with the first flow collecting groove 11141. The first flow collecting groove 11141 is used to receive the accumulated liquid of the second flow collecting groove 11142, and the drain hole 1115 is arranged at the lowest point of the first flow collecting groove 11141.

[0081] Specifically, by providing the first flow collecting groove 11141 and the second flow collecting groove 11142, on the one hand, the structural strength of the bottom plate body 1101 can be effectively guaranteed, and on the other hand, a multi-section diversion structure can be formed to reduce the bottom area of a single flow collecting groove, improve the fluidity of the condensed water, and avoid the situation of condensed water staying due to a large amount of water entering the outdoor unit 1.

[0082] It should be understood that as Figure 3 and Figure 4 shown, the first flow collecting groove 11141 is arranged in the middle of the bottom plate body 1101. The first flow collecting groove 11141 is the flow collecting groove with the deepest depth, and the drain hole 1115 is arranged in the first flow collecting groove 11141. In this embodiment, the condensed water entering the outdoor unit 1 will enter the first flow collecting groove 11141 under the guidance of the multiple protrusions and the second flow collecting groove 11142, and finally be discharged from the drain hole 1115 of the first flow collecting groove 11141. Among them, the second flow collecting groove 11142 and the second protrusion 11122 are respectively arranged on opposite sides of the first flow collecting groove 11141. One of the second protrusions 11122 is arranged inside the first flow collecting groove 11141, and the depth of the second flow collecting groove 11142 is less than that of the first flow collecting groove 11141. Optionally, the number of the second flow collecting grooves 11142 is two, and the two second flow collecting grooves 11142 are arranged at intervals along the width direction of the bottom plate body 1101. By limiting the depth, position and number of the second flow collecting grooves 11142, the condensed water can quickly enter the first flow collecting groove 11141 from one side in the length direction of the bottom plate body 1101, which helps to improve the structural strength of the bottom plate body 1101 and ensure the guiding effect on the condensed water.

[0083] It should be noted that, in addition to the above structure, the second confluence trough 11142 can also be set to other structures, and specifically can be adjusted by changing the number, position, depth, etc. of the second confluence trough 11142. Among them, the second confluence trough 11142 is communicated with the first confluence trough 11141 to ensure that the condensed water falling into the second confluence trough 11142 can be guided into the first confluence trough 11141.

[0084] Furthermore, the protrusion 1112 further includes a fourth protrusion 11124. One end of the fourth protrusion 11124 is connected to the first protrusion 11121, and the other end of the fourth protrusion 11124 is connected to at least one of the three second protrusions 11122. And / or, the protrusion 1112 further includes a fifth protrusion 11125, and the fifth protrusion 11125 is connected to at least two of the three second protrusions 11122. And / or, the protrusion 1112 further includes a sixth protrusion 11126, and the sixth protrusion 11126 is arranged on one side edge of the bottom plate body 1101 and is connected to at least two of the second protrusions 11122.

[0085] Specifically, by providing a plurality of protrusions such as the fourth protrusion 11124, the fifth protrusion 11125 and the sixth protrusion 11126, it is helpful to further improve the structural strength of the bottom plate body 1101. At the same time, it can also cooperate with the first protrusion 11121 and the second protrusion 11122 to form a stepped diversion structure, which is helpful to further promote the flow of accumulated water, thereby preventing the occurrence of dead water areas.

[0086] It can be understood that the fourth protrusion 11124 is arranged between the first protrusion 11121 and the second protrusion 11122 and is located inside the first confluence trough 11141. Among them, one end of the fourth protrusion 11124 is connected to the first protrusion 11121, and the other end of the fourth protrusion 11124 is connected to the second protrusion 11122 located in the first confluence trough 11141. At this time, the second protrusion 11122, the fourth protrusion 11124 and the first protrusion 11121 are communicated and divide the first confluence trough 11141. Optionally, the protrusion height of the fourth protrusion 11124 is less than the protrusion height of the first protrusion 11121.

[0087] In this embodiment, the fifth protrusion 11125 is disposed at one side edge of the first confluence groove 11141. One end of the fifth protrusion 11125 is connected to one of the second protrusions 11122, and the other end of the fifth protrusion 11125 is connected to the second protrusion 11122 located in the first confluence groove 11141. Optionally, the protrusion height of the fifth protrusion 11125 is less than the protrusion height of the second protrusion 11122 and is the same as the protrusion height of the fourth protrusion 11124. At the same time, the fifth protrusion 11125 communicates with the first confluence groove 11141. With such a setting, the condensed water falling into the outdoor unit 1 will not flow to the second protrusion 11122 and will flow toward the first confluence groove 11141.

[0088] As Figures 2 - 4 shown, the sixth protrusion 11126 is disposed at one side edge of the bottom plate body 1101. In this embodiment, the number of the sixth protrusions 11126 is two, and they are spaced along the width direction of the bottom plate body 1101. The two sixth protrusions 11126 are respectively connected to two of the second protrusions 11122. The setting of the sixth protrusion 11126 helps to further improve the structural strength of the bottom plate body 1101. Among them, the protrusion heights of the two sixth protrusions 11126 may be the same or different. At the same time, the sixth protrusion 11126 can be set as a stepped structure, that is, the sixth protrusion 11126 has two protrusion heights, and one of the protrusion heights of the sixth protrusion 11126 can be the same as the protrusion height of the fourth protrusion 11124. One of the protrusion heights of the sixth protrusion 11126 is greater than the protrusion height of the second protrusion 11122.

[0089] It should be noted that by disposing the sixth protrusion 11126 at one side edge of the bottom plate body 1101, other connection structures can be provided on the sixth protrusion 11126 to cooperate with other components of the outdoor unit 1 for connection, such as embedding grooves and mounting holes.

[0090] Further, the protrusion 1112 further includes a seventh protrusion 11127. The seventh protrusion 11127 is disposed inside the first confluence groove 11141 and is connected to one side edge of the bottom plate body 1101. The seventh protrusion 11127 can divide the first confluence groove 11141, and / or the protrusion further includes an eighth protrusion 11128. The eighth protrusion 11128 is disposed at one side of the first confluence groove 11141.

[0091] Specifically, by providing the seventh protrusion 11127 and the eighth protrusion 11128, the structural strength of the first confluence groove 11141 can be further improved. At the same time, the setting of the seventh protrusion 11127 can further cut the first confluence groove 11141, thereby reducing the bottom area of the first confluence groove 11141, which helps to further improve the diversion effect on the condensed water.

[0092] It should be understood that along the width direction of the bottom plate body 1101, an eighth protrusion 11128 is provided on one side of the first confluence groove 11141. Optionally, the eighth protrusion 11128 communicates with one side in the width direction of the bottom plate body 1101. At this time, the eighth protrusion 11128 communicates with the first confluence groove 11141, so that the condensed water falling into the eighth protrusion 11128 can be guided into the first confluence groove 11141. In this embodiment, a seventh protrusion 11127 is provided inside the first confluence groove 11141, and the seventh protrusion 11127 is arranged at an interval from the eighth protrusion 11128. One end of the seventh protrusion 11127 is connected to one of the second protrusions 11122, the fourth protrusion 11124, and the fifth protrusion 11125 at the same time, and communicates with one side in the length direction of the bottom plate body 1101 through the second protrusion 11122 and the sixth protrusion 11126.

[0093] It should be noted that the protrusion height of the seventh protrusion 11127 is the same as that of the eighth protrusion 11128. At the same time, the protrusion height of the seventh protrusion 11127 is greater than the protrusion height of the fourth protrusion 11124 (the fifth protrusion 11125), and less than the protrusion height of the second protrusion 11122. Such a setting helps to form a continuous diversion structure with different heights. And at this time, the diversion structure communicates with the first confluence groove 11141. Moreover, as Figure 3 shown, the seventh protrusion 11127 communicates with other protrusions, and can divide the first confluence groove 11141 into three diversion channels, and finally converge at the drain hole 1115. Furthermore, the condensed water entering the outdoor unit 1 can be guided to the drain hole 1115.

[0094] It should be further understood that the confluence groove 1114 includes a plurality of third confluence grooves 11143, and the plurality of third confluence grooves 11143 are arranged on the top surfaces of the plurality of protrusions 1112, and each third confluence groove 11143 communicates with the first confluence groove 11141 respectively. By providing the third confluence groove 11143 and arranging the third confluence groove 11143 on the protrusion 1112, it helps to improve the structural strength of the protrusion 1112, and further improves the drainage effect of the bottom plate body 1101. Specifically, the third confluence groove 11143 is arranged on the fourth protrusion 11124, and at the same time, the third confluence groove 11143 is arranged on the seventh protrusion 11127. Optionally, the number of the third confluence grooves 11143 is two, and the third confluence grooves 11143 are arranged at intervals along the length direction of the bottom plate body 1101 on the seventh protrusion 11127. At the same time, the third confluence grooves 11143 all communicate with the first confluence groove 11141 to be able to guide the condensed water into the first confluence groove 11141.

[0095] It should be noted that the third confluence groove 11143 can be arranged not only on the fourth protrusion 11124 and the seventh protrusion 11127, but also on other protrusions. In this embodiment, the third confluence groove 11143 is arranged on two of the third protrusions 11123, and mounting holes are arranged on the third confluence groove 11143 for mounting a heat exchanger or other components, etc.

[0096] Furthermore, a first diversion slope 1171 is arranged at the edge of each protrusion 1112, and / or a second diversion slope 11172 is arranged at the edge of each confluence groove 1114.

[0097] The side surface of each protrusion 1112 is configured as a first diversion slope, and the first diversion slope is inclined relative to the top surface of the protrusion 1112, and / or the side wall of each confluence groove 1114 is configured as a second diversion slope, and the second diversion slope is inclined relative to the top surface of the protrusion 1112.

[0098] Specifically, by arranging the first diversion slope 1171 and the second diversion slope 11172, on the one hand, it helps to reduce the manufacturing difficulty of the protrusions 1112 and the confluence grooves 1114 of the bottom plate body 1101, ensuring the uniform thickness of each part of the bottom plate body 1101 during stamping preparation, and on the other hand, it can further improve the diversion effect of the bottom plate body 1101.

[0099] It should be understood that, as Figures 7 - 10 shown, the side surface of each protrusion 1112 is arranged as the first diversion slope 1171. At the same time, the side wall of each confluence groove 1114 is arranged as the second diversion slope 11172. The first diversion slope 1171 and the second diversion slope 11172 cooperate to quickly guide the condensed water into the drain hole 1115. Optionally, the inclination angle of the second diversion slope 11172 is the same as or different from that of the first diversion slope 1171, and the inclination angle of the second diversion slope 11172 and the first diversion slope 1171 is greater than the inclination angle of the diversion slope 1102. With such an arrangement, it can effectively ensure that the condensed water falling on the outdoor unit 1 can be timely collected near the drain hole 1115 and discharged.

[0100] It should be noted that when the protrusion 1112 is adjacent to the confluence groove 1114, a part of the side surface of the protrusion 1112 is the side wall of the confluence groove 1114, that is, the first diversion slope 1171 and the second diversion slope 11172 are the same inclined structure.

[0101] It should be further understood that the border 1113 extends along the circumferential direction of the bottom plate body 1101, and the border 1113 is used to connect with the side plate of the outdoor unit 1. By providing the border 1113, the bottom plate body 1101 can be connected to the side plate of the box body 10, which helps to improve the convenience of installing the box body 10 and can also enhance the structural strength of the bottom plate 111. In this embodiment, the border 1113 is connected to the side plate of the box body 10 through a screw connector, with simple operation and good connection effect.

[0102] In this embodiment, a reinforcing rib 1111 is provided at the connection between the border 1113 and the bottom plate body 1101. The reinforcing rib 1111 extends along the circumferential direction of the bottom plate body 1101, and the reinforcing rib 1111 has a guiding surface communicating with the diversion inclined surface 1102. Optionally, a circular reinforcing rib 1111 is provided at the connection between the border 1113 and the bottom plate body 1101. By providing the circular reinforcing rib 1111, it helps to improve the connection strength between the border 1113 and the bottom plate body 1101, and further enhance the structural strength of the bottom plate 111.

[0103] It should be noted that in this embodiment, the protruding height of the reinforcing rib 1111 can be the same as or different from the protruding height of the third protrusion 11123. When the protruding height of the reinforcing rib 1111 is the same as the protruding height of the third protrusion 11123, the guiding surface is smoothly transitioned with the top surface of the above-mentioned third protrusion 11123, or the guiding surface and the top surface of the above-mentioned third protrusion 11123 are located on the same plane. The setting of the reinforcing rib 1111 helps to improve the structural strength of the bottom plate 111. In cooperation with the concave and convex structures of the bottom plate body 1101, it extends the service life of the bottom plate 111; on the other hand, it can make the guiding surface of the reinforcing rib 1111 cooperate with the diversion inclined surface 1102, thereby further enhancing the drainage effect of the bottom plate 111 and improving the drainage concentration of the bottom plate 111.

[0104] It should be further understood that a plurality of reinforcing grooves 1116 are provided on the border 1113, and the plurality of reinforcing grooves 1116 are arranged at intervals along the circumferential direction of the bottom plate body 1101. By providing the reinforcing grooves 1116, it helps to improve the structural strength of the border 1113, and further enhance the structural strength of the bottom plate 111. In this embodiment, several reinforcing grooves 1116 are provided on the border 1113. The number of the reinforcing grooves 1116 is multiple, and along the circumferential direction of the bottom plate body 1101, the plurality of reinforcing grooves 1116 are respectively arranged on the border 1113. Among them, the protruding direction of the reinforcing groove 1116 can protrude towards the inside of the box body 10 or protrude towards the outside away from the box body 10.

[0105] In the second aspect of the present invention, an outdoor unit 1 is proposed, including the above-mentioned bottom plate 111. As Figures 1 - 3As shown in the figure, a chassis assembly 11 is provided at the bottom of the outdoor unit 1. The chassis assembly 11 includes a bottom plate 111 and feet 112. Among them, the bottom plate 111 has a bottom plate body 1101 and a border 1113. The feet 112 are adaptively connected to the bottom plate body 1101, and the border 1113 is connected to the side plate of the cabinet 10. By providing a plurality of protrusions 1112 and a plurality of confluence grooves 1114 on the bottom plate body 1101, it can cooperate with the diversion inclined surface 1102, so that the condensed water accumulated in the outdoor unit 1 can quickly drain through a drain hole 1115. This can not only effectively ensure the timely collection and discharge of the condensed water falling on the outdoor unit 1, help eliminate dead water areas, prevent the chassis from rusting due to water accumulation, thereby extending the service life of the bottom plate body 1101, but also avoid affecting the user's usage environment and help solve the problem of poor drainage concentration of the existing chassis. At the same time, by setting confluence grooves 1114 and protrusions 1112 with different depths, it helps to improve the structural strength of the bottom plate 111, thereby avoiding the problem of deformation due to insufficient strength.

[0106] The second aspect of the present invention proposes a heating, ventilation and air conditioning equipment, including the above-mentioned outdoor unit 1.

[0107] Compared with the prior art, the heating, ventilation and air conditioning equipment proposed by the present invention has the technical advantages possessed by the above-mentioned outdoor unit 1, which will not be elaborated here.
