The top cover 300 extends above the electric control box 400, which can protect the electric control box 400, and the water guide groove 310 is arranged on the upper side of the top cover 300 corresponding to the electric control box 400, which can guide the water on the top cover 300 to the side of the top cover 300 in time to avoid excessive water leakage to the electric control box 400. It can be understood that the water outlet side of the water guide groove 310 should avoid the electric control box 400 to reduce the risk of water entering the electric control box 400 as much as possible.

[0036] In an embodiment, the shell 100 is formed with a stepped structure 210, and the electric control box 400 is attached to the concave side of the stepped structure 210. In this way, the adjacent two side surfaces of the electric control box 400 can be close to the two step surfaces of the stepped structure 210 respectively, so as to enhance the support of the shell 100 to the electric control box 400 and improve the installation stability of the electric control box 400. Specifically, the peripheral side of the electric control box 400 has four side surfaces, two adjacent side surfaces are attached to the two step surfaces of the stepped structure 210 respectively, and the other two adjacent side surfaces are exposed. Of course, in other embodiments, three side surfaces of the peripheral side of the electric control box 400 can also be exposed.

[0037] Without loss of generality, the stepped structure 210 is formed by the base 200 of the shell 100, and the electric control box 400 is installed on the base 200. Of course, in other embodiments, the stepped structure 210 can also be formed by the side wall erected on the base 200.

[0038] In an embodiment, the water guide groove 310 includes a first water guide groove 311, which is L-shaped and is arranged at the corner of the step structure 210. It can be understood that the inner side of the shell 100 is formed with a mounting space for accommodating components such as heat exchangers, and the top cover 300 can be divided into two regions, a region above the mounting space and a region above the electric control box 400, and the first water guide groove 311 is located at the boundary between the two regions, which can reliably guide the water flow in the two regions out, and the first water guide groove 311 is L-shaped, which can collect water flow on the top cover 300 in multiple directions, thereby reliably forming a water blocking line for the electric control box 400 to reduce the risk of water entering the electric control box 400. Of course, in other embodiments, two L-shaped water guide grooves 310 can be arranged at the two surfaces of the step structure 210 corresponding to the corner.

[0039] In an embodiment, the first water guide groove 311 is provided with a first fastening hole 321 for fastening and connecting the top cover 300 and the electric control box 400. Specifically, the first fastening hole 321 is used for the fastener to pass through, so that the top cover 300 and the electric control box 400 can be fastened and connected by the fastener, wherein the fastener includes screws, bolts, pins and rivets, etc., so that the top cover 300 and the electric control box 400 can be reliably connected, thereby improving the installation stability of the electric control box 400. Moreover, the first fastening hole 321 is arranged at the first water guide groove 311, which can utilize the recessed structure of the first water guide groove 311, so that after the fastener is installed, the head of the fastener will not protrude out of the top cover 300, thereby reducing the safety hazard. Of course, in other embodiments, a recess can be arranged at other positions of the top cover 300, and a fastening hole can be arranged in the recess for fastening and connecting the top cover 300 and the electric control box 400, or the side wall can be used instead of the top cover 300 to connect the electric control box 400.

[0040] In an embodiment, the water guide groove 310 includes a second water guide groove 312, which extends along the length direction of the top cover 300 and is located at the edge of the side of the top cover 300 away from the corner of the step structure 210. It can be understood that the water flow in the center of the top cover 300 generally has a tendency to spread to the periphery, and when the water flow spreads to the side of the top cover 300 away from the corner of the step structure 210, the water flow is more likely to flow to the position of the electric control box 400. In this embodiment, the second water guide groove 312 is arranged at the side to strengthen the guidance of the water flow, thereby reliably guiding the water flow to the side of the top cover 300 to avoid the water flow spreading to the direction of the electric control box 400. Moreover, the second water guide groove 312 cooperates with the first water guide groove 311 to reliably guide the water flow in various directions to the side of the top cover 300, thereby effectively reducing the risk of water entering the electric control box 400.

[0041] In an embodiment, the second water guide groove 312 is provided with a flow guide section 313 at the corner. Specifically, the flow guide section 313 is provided at a side of the second water guide groove 312 close to the corner of the stepped structure 210, so as to enhance the water guide capability of the second water guide groove 312, thereby enhancing the water blocking capability of the area of the electric control box 400, so as to further reduce the risk of water entering the electric control box 400.

[0042] In an embodiment, the second water guide groove 312 is provided with a second fastening hole 322 for fastening and connecting the top cover 300 and the electric control box 400. Specifically, the second fastening hole 322 is used for passing a fastener, so that the top cover 300 and the electric control box 400 can be fastened and connected by the fastener, wherein the fastener includes a screw, a bolt, a pin shaft, a rivet, etc., so as to ensure reliable connection of the top cover 300 and the electric control box 400, thereby improving the installation stability of the electric control box 400. Moreover, the second fastening hole 322 is provided at the second water guide groove 312, so that the recessed structure of the second water guide groove 312 can make the head of the fastener not protrude out of the top cover 300 after installation of the fastener, thereby reducing the safety hazard. In addition, the first fastening hole 321 and the second fastening hole 322 cooperate with each other, so that multiple positions of the top cover 300 and the electric control box 400 can be connected, thereby further improving the installation stability of the electric control box 400.

[0043] In an embodiment, the second water guide groove 312 is provided with a third fastening hole 323 for fastening and connecting the top cover 300 and the side wall of the shell 100. Specifically, the third fastening hole 323 is used for passing a fastener, so that the top cover 300 and the side wall can be fastened and connected by the fastener, wherein the fastener includes a screw, a bolt, a pin shaft, a rivet, etc., so as to ensure reliable connection of the top cover 300 and the side wall, thereby ensuring the stability of the external structure of the air conditioner. Moreover, the third fastening hole 323 is provided at the second water guide groove 312, so that the recessed structure of the second water guide groove 312 can make the head of the fastener not protrude out of the top cover 300 after installation of the fastener, thereby reducing the safety hazard. Of course, in other embodiments, a recess can also be provided at another position of the top cover 300, and a fastening hole can be provided in the recess for fastening and connecting the top cover 300 and the side wall.

[0044] It can be understood that the fastener is generally provided with a sealing gasket, which can effectively seal the fastening hole when the fastener is fastened and connected to the fastening hole, so as to avoid water flow from the fastening hole to the bottom side of the top cover 300, thereby avoiding the risk of water seepage.

[0045] In an embodiment, the edge of the water guide groove 310 is provided with a drainage surface 314. Specifically, the edge of the water guide groove 310 on the water inlet side and the edge on the water outlet side can be provided with the drainage surface 314, which can be a slope or an arc surface, etc. In this way, the guidance of the water flow can be enhanced, and on the water inlet side, the water flow is promoted to flow into the water guide groove 310, and on the water outlet side, the water flow is promoted to flow out of the water guide groove 310, thereby reducing the risk of water entering the air conditioner as a whole.

[0046] In an embodiment, the electric control box 400 is conductively connected to at least one of the base 200 and the top cover 300. In this way, the grounding continuity between the electric control box 400 and the shell of the air conditioner can be ensured, which is conducive to improving the safety performance of the air conditioner. If a short circuit or an electric leakage fault occurs inside the electric control box 400, the grounding continuity can ensure that the current flows back to the power supply through the low-impedance grounding path, rather than through the human body, thereby avoiding electric shock accidents when the user touches the air conditioner shell. When an electrical fault occurs, a good grounding system can help quickly trigger an overcurrent protection device (such as a circuit breaker or fuse) to cut off the circuit, reduce the risk of electrical fire, and protect the safety of users and maintenance personnel. In addition, the grounding continuity helps to protect sensitive electronic components inside the electric control box 400 from electrostatic discharge (ESD) and other electrical transient phenomena, prolongs the service life of electronic components, and helps to reduce electromagnetic interference from external sources or the air conditioner's own electronic equipment, ensuring that it works normally without interfering with other electronic equipment. In addition, it can also improve the stability and reliability of the control signal, ensuring that the air conditioner runs more smoothly and efficiently. Of course, in other embodiments, the electric control box 400 can also be grounded in other ways.

[0047] In an embodiment, the electric control box 400 is mounted on the base 200, and the electric control box 400 is fixed and conductively connected to at least one of the base 200 and the top cover 300 by a fastener. That is, the fastener is configured as a conductor, while achieving the fastening connection and conductive connection between the electric control box 400 and the base 200 or the top cover 300, which not only ensures the stability of the installation of the electric control box 400, but also ensures the reliable grounding of the electric control box 400. Further, by using the fastener to achieve the above two functions, it is also conducive to simplifying the structure of the air conditioner. Of course, in other embodiments, the electric control box 400 can also be connected to the shell components of the air conditioner by welding.

[0048] In an embodiment, the air conditioner is configured as a kitchen air conditioner. That is, the air conditioner is installed in the kitchen to regulate the air in the kitchen, which can include regulating the air temperature and the concentration of cooking fumes, thereby providing a comfortable environment for people in the kitchen, especially when cooking in summer, to avoid discomfort caused by high temperature.

[0049] Specifically, the air conditioner is configured as a whole air conditioner, comprising a first module 510 and a second module 520, the first module 510 is configured to exchange heat with air in an indoor environment, the second module 520 is configured to exchange heat with air in an outdoor environment, the first module 510 and the second module 520 are arranged at intervals in the same base 200, and the electric control box 400 is arranged close to the first module 510. In this way, the interval between the first module 510 and the second module 520 can avoid the structure in the installation environment, for example, when it is necessary to be installed on the ceiling, the interval can avoid the joist, so that the air conditioner can be more flexible. When the condensation water on the ceiling drops on the first module 510, because the top cover 300 extends above the electric control box 400, the electric control box 400 is shielded, so that the electric control box 400 can be protected, and the condensation water on the ceiling is prevented from dropping on the top of the electric control box 400 in a high-temperature and humid environment, and the top cover 300 is designed with a water guide groove 310, which can guide the condensation water to flow out along a specified route, so as to prevent the condensation water from accumulating for a long time and penetrating into the electric control box 400. In addition, the second module 520 is configured with a compressor, so that the length of the second module 520 is longer than the length of the first module 510, the electric control box 400 is installed close to the first module 510, the space on the side of the first module 510 can be used, so that the length of the first module 510 and the length of the second module 520 are equivalent, which is beneficial to improve the overall appearance of the air conditioner and reduce the requirement of the air conditioner on the installation space.

[0050] Of course, in other embodiments, the air conditioner can also be configured as a split air conditioner, and the above structure is arranged on an outdoor unit of the split air conditioner, or the air conditioner is only used as an outdoor unit of a split air conditioner.

[0051] The above description is only an exemplary embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
