Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a waterproof structure, an outdoor unit and an air conditioner. Background Art

[0002] In related art, the electronic control components of an air conditioner's outdoor unit tend to be fixed within the unit, typically located in the upper right corner. Cooling and heat dissipation are achieved through air outlets on the central partition. The rotation of the blades in the air duct creates negative pressure, which in turn generates airflow through the central partition's outlets, removing heat generated by the electronic control components. The central partition's outlets can affect the cooling and heat dissipation of the electronic control components. To prevent water and insects, a fixed "maze circuit" structure is often used, with additional grille structures added for insect protection. However, this complex structure significantly reduces the wind intensity of the electronic control components, causing the temperature of the electronic control components to rise due to insufficient heat dissipation, resulting in reduced reliability.

[0003] Therefore, the waterproof structure of the air conditioner outdoor unit needs to be further simplified to improve the waterproof and insect-proof effects while improving the heat dissipation effect of the electronic control components. Utility Model Content

[0034] First, see Figure 1 and Figure 2 An embodiment of the present application provides a waterproof structure 10, which is suitable for an outdoor unit 100. The waterproof structure 10 includes a rotatably connected enclosure 11 and a baffle 12. The enclosure 11 defines an opening 114, and the baffle 12 is located in the opening 114. The outdoor unit 100 includes a middle partition 20, which has an air outlet 21. The enclosure 11 and the middle partition 20 are connected to connect the opening 114 and the air outlet 21, and the baffle 12 rotatably opens or closes the air outlet 21.

[0035] The waterproof structure 10 provided by the present application has an opening 114 connected to the air outlet 21. When the baffle 12 located in the opening 114 of the enclosure 11 is rotated and opened, the air outlet 21 is opened, which is conducive to airflow through for heat dissipation. The airflow channel and the air outlet 21 are of the same size, which is conducive to increasing the air output and thus improving the heat dissipation effect. When the baffle 12 located in the opening 114 of the enclosure 11 is closed, the air outlet 21 is sealed, which can effectively prevent insects and rodents from passing through and prevent rainwater from penetrating, achieving the effect of insect repellent and waterproofing. The waterproof structure 10 provided by the present application is simple and improves the airflow channel of the complex maze structure. While meeting the requirements of insect repellent and waterproofing, it greatly increases the air outlet area and improves the air cooling and heat dissipation effect.

[0036] It should be noted that when the waterproof structure 10 is applied to an air conditioner, the baffle 12 can automatically rotate to open or close the air outlet 21 according to the direction of the air flow in the air conditioner. For example, when the fan in the air conditioner is operating normally, the rotation of the fan generates negative pressure, causing the baffle 12 to rotate to open the air outlet 21, which is beneficial to heat dissipation in the electronic control area; when the air conditioner is turned on the dust removal mode and the fan needs to be reversed, or when the air conditioner is stationary in a typhoon-prone area and the fan is blown to reverse by the typhoon, the wind field flow path generated by the air duct at this time is opposite to that in normal operation, and the baffle 12 will fit tightly on the air outlet 21 in the reverse direction to close the air outlet 21, thereby preventing rainwater from entering the electronic control area through the reverse wind field.

[0037] In some embodiments, the enclosure 11 includes a first side panel 111, a second side panel 112, and a bottom panel 113 connecting the first side panel 111 and the second side panel 112, and the baffle 12 includes a rotating connection end 121 and a free end 122, the rotating connection end 121 is rotatably connected to the side of the first side panel 111 and the second side panel 112 away from the bottom panel 113, the free end 122 is close to the bottom panel 113, and can rotate around the rotating connection end 121 to open or close the air outlet 21.

[0038] In some embodiments, the orthographic projection of the baffle 12 on the plane where the middle partition 20 is located can completely cover the air outlet 21, so that when the baffle 12 is stationary, the air outlet 21 is completely sealed by the baffle 12 to prevent the infiltration of insects, rodents and rainwater. It can be understood that the orthographic projection of the opening 114 on the plane where the middle partition 20 is located can completely cover the orthographic projection of the baffle 12 on the plane where the middle partition 20 is located. In other words, there are gaps between the baffle 12 and the first side panel 111, the second side panel 112 and the bottom panel 113. This facilitates the smooth rotation of the baffle 12, and when the baffle 12 rotates to open the air outlet 21, the airflow blown out of the air outlet 21 can pass through the gaps to improve the heat dissipation effect.

[0039] In some embodiments, the baffle 12 has a first connection hole, the enclosure 11 has a second connection hole, and the waterproof structure 10 further includes a first connection member 13, which is fixedly connected to the second connection hole and rotatably connected to the first connection hole. It can be understood that the first side panel 111 and the second side panel 112 both have second connection holes, and the ends of the baffle 12 respectively have first connection holes corresponding to the second connection holes on the first side panel 111 and the second side panel 112. The line connecting the second connection holes on the first side panel 111 and the second side panel 112 is the rotation axis of the baffle 12.

[0040] Specifically, the first connecting member 13 can be a rivet, or a protrusion extending along the direction of the opening 114 on the first side plate 111 and the second side plate 112. The rivet or protrusion passes through the first connecting hole, and the baffle 12 can rotate around the rivet or protrusion through the first connecting hole to realize the rotation of the baffle 12.

[0041] In other embodiments, the enclosure 11 and the baffle 12 may also be rotationally connected by conventional means known in the art, such as by latches, hinges, and the like.

[0042] In some embodiments, a stopper 1131 is protruding from the bottom plate 113 to limit the opening angle of the baffle 12. When the baffle 12 is rotated to its maximum opening angle, the baffle 12 and the stopper 1131 abut against each other. Furthermore, the stopper 1131 is located on the side of the bottom plate 113 away from the opening 114. This prevents insects, rodents, and rainwater from infiltrating the air outlet 21 and damaging the electronic control components 40 when the fan speed is too high and the baffle 12 rotates to an excessively large angle.

[0043] In some embodiments, a counterweight 1221 is provided on the free end 122. The counterweight 1221 is configured to abut the free end 122 against the middle partition 20, thereby closing the air outlet 21. Specifically, the counterweight 1221 is located on the side of the free end 122 near the bottom plate 113. When the waterproof structure 10 is installed in an air conditioner and the air conditioner is stationary, the counterweight 1221 can further promote the abutment between the free end 122 and the middle partition 20, allowing the baffle 12 to close the air outlet 21. When the air conditioner is operating, the counterweight 1221 can reduce the opening angle of the baffle 12, resulting in a smaller air outlet 21. This can both promote airflow and heat dissipation and improve the insect and water repellent effects.

[0044] In other embodiments, a spring is provided between the baffle 12 and the middle partition 20 along the rotation direction of the baffle 12, and the baffle 12 and the middle partition 20 are connected by the spring. When the fan is running, the thrust generated by the airflow is greater than the elastic force, so that the baffle 12 can be rotated around the rotating connection end 121 to open the air outlet 21, and the spring undergoes elastic deformation at this time; when the fan stops running, the spring restores the elastic deformation, and under the action of elastic force and gravity, the baffle 12 rotates to close the air outlet 21 to prevent the infiltration of insects, rodents and rainwater.

[0045] In some embodiments, the enclosure 11 further includes a first connection portion 14 disposed around the opening 114 , and the middle partition 20 further includes a second connection portion 22 disposed around the air outlet 21 , and the first connection portion 14 and the second connection portion 22 are fixedly connected.

[0046] Furthermore, the first connecting portion 14 is a folded edge extending from the side of the enclosure 11 away from the opening 114. The folded edge can be connected to the side of the first side panel 111 or the second side panel 112 near the air outlet 21, or to the side of the bottom panel 113 near the air outlet 21. The folded edge is provided with a second connecting hole, and the second connecting portion 22 includes a third connecting hole. The second connecting member connects the third connecting hole and the third connecting hole to achieve a fixed connection between the waterproof structure 10 and the middle partition 20. It can be understood that the folded edge is arranged to fit the outer wall of the middle partition 20.

[0047] In other embodiments, the waterproof structure 10 and the middle partition plate 20 may also be rotationally connected by conventional means known in the art, such as snap connection, adhesive connection, etc.

[0048] Second, see Figure 3 and Figure 4 The embodiment of the present application further provides an outdoor unit 100 , which includes a middle partition 20 and the above-mentioned waterproof structure 10 .

[0049] In some embodiments, a rib 23 is provided around the air outlet 21, extending in a direction close to the waterproof structure 10. The rib 23 can prevent condensed water from flowing down the surface of the middle partition 20 from seeping into the electronic control area through the air outlet 21, further improving the waterproof effect.

[0050] In some embodiments, the outdoor unit 100 further includes a housing 30 and an electronic control component 40. The central partition 20 divides the housing 30 into a fan chamber 31 and a compressor chamber 32. The electronic control component 40 is located within the compressor chamber 32, and the vent of the electronic control component 40 is connected to the air outlet 21. Furthermore, the waterproof structure 10 is located within the fan chamber 31, and the baffle 12 rotates along one side of the fan chamber 31.

[0051] Specifically, an air inlet is provided on the housing 30 on the side of the compressor chamber 32. The air inlet, the electronic control component 40, the air outlet 21, and the fan chamber 31 are sequentially connected. When the air conditioner is in operation, the fan blades on the side of the fan chamber 31 rotate, driving air flow and generating negative pressure. Airflow enters the compressor chamber 32 from the air inlet and then passes through the electronic control component 40 from bottom to top. The rotation of the fan drives the baffle 12 to rotate and open the air outlet 21. The airflow passing through the electronic control component 40 flows through the air outlet 21 into the fan chamber 31, thereby removing the heat generated by the operation of the electronic control component 40.

[0052] In the waterproof structure 10 provided by the present application, the area of ​​the air outlet 21 can be enlarged as needed, thereby increasing the air outlet area and improving the heat dissipation effect. When stationary, the baffle 12 can freely hang down under the action of gravity and abut against the air outlet 21, thereby improving the insect and rodent prevention and waterproofing effects, thereby ensuring the normal operation of the electronic control component 40 and improving the reliability of the electronic control component 40.

[0053] In a third aspect, an embodiment of the present application further provides an air conditioner, which includes the outdoor unit 100 described above.
