[0048] The heat dissipation component in the electrical box of an air conditioner's outdoor unit is crucial to the proper operation of the electrical system. Its core function is to help maintain the system's normal operating temperature and prevent overheating that could lead to performance degradation or failure of electrical components. Because air conditioner outdoor units operate outdoors for extended periods of time, the heat sinks in the electrical box are at risk of being exposed to rain. This exposure poses safety risks such as moisture, corrosion, and short circuits.
[0049] Based on this, the following embodiments are proposed.
[0050] Example 1:
[0051] like Figure 1 、 2 As shown, this embodiment provides an electrical box assembly for an air conditioner outdoor unit, comprising:
[0052] The housing 5 is provided with a device mounting side, and the device mounting side is provided with a heat dissipation component 6 and a fan component;
[0053] A water shield 1 is movably provided on the device installation side and is used to selectively shield the device installation side;
[0054] The water shield 1 and the fan assembly are configured to have a linkage relationship: when the water shield 1 is closed on the device installation side, the fan assembly is turned on; when the water shield 1 is opened on the device installation side, the fan assembly is turned off;
[0055] The open state of the water shield 1 is a non-rainproof state, and the closed state of the water shield 1 is a rainproof state.
[0056] In this embodiment, the housing 5 is the housing of the electrical box assembly, a heat dissipation assembly is provided on the device installation side of the housing 5, and an electrical component that needs to dissipate heat is provided on the other side of the device installation side. The heat dissipation assembly is connected to the electrical component for dissipating heat for the electrical component, and the water shield 1 is rotatably connected to the opening of the housing 5, that is, the water shield 1 is equivalent to the door of the housing 5, and the water shield 1 can be opened and closed at the opening of the housing 5. When the water shield 1 is opened, it is in a non-rainproof state. At this time, there is no rain falling in the external environment, and the electrical box assembly as a whole is in a non-rainproof state, which does not affect the normal heat dissipation work of the heat dissipation assembly 6;
[0057] When rain falls in the external environment, the water shield 1 is converted from an open state to a closed state, that is, from a non-rainproof state to a rainproof state, which effectively protects the heat dissipation component 6 from rain, preventing it from getting damp, being easily corroded, short-circuited and other safety hazards, and affecting the electrical components inside. Preferably, when the water shield 1 is in the rainproof state, its end can fit with the side wall of the shell 5 to have a better rainproof effect; when the water shield 1 is in the closed state, the fan component starts working at the same time to assist the heat dissipation of the heat dissipation component 6, and when the water shield 1 is in the open state, the fan component stops working. By setting the fan component to be linked with the water shield 1, the electrical box component can have a good heat dissipation effect even in the rainproof state. The water shield 1 automatically opens on non-rainy days and the fan component stops working at the same time, avoiding ineffective work and achieving energy saving and life extension of the fan component itself.
[0058] Optionally, in an implementation of this embodiment, as Figure 3 、 4 As shown,
[0059] The electrical box assembly includes:
[0060] The shaft system assembly includes a first shaft system assembly 201, and the first shaft system assembly 201 is transmission-connected to the water shield 1 to drive the water shield 1 to open or close;
[0061] The first detection component is used to detect whether the air conditioner outdoor unit is in a rain state;
[0062] The controller, the first detection component and the first shaft system component 201 are all electrically connected to the controller, and the controller is designed to: control the first shaft system component 201 to drive the water shield 1 to be in a rainproof state or a non-rainproof state according to the detection result of whether the air-conditioning outdoor unit is in a rainproof state.
[0063] In this embodiment, the shaft system assembly realizes automatic closing and resetting of the water shield 1. It can automatically close on rainy days to protect the heat dissipation assembly 6 from being affected by rain, and automatically reset and open on sunny days without affecting the normal heat dissipation operation of the heat dissipation assembly 6. The fan assembly is electrically connected to the control. When the controller controls the water shield 1 to open, it also controls the fan assembly to stop working. When the controller controls the water shield 1 to close, it also controls the fan assembly to start working, maintaining a linkage relationship between the two. The working state of the first shaft system assembly 201 is controlled by the controller. When the water shield 1 opens or closes, when the air-conditioning outdoor unit is in a rainy state, the controller controls the first shaft system assembly 201 to drive the water shield 1 to close the water shield 1, so that it is in a rainproof state, avoiding the heat dissipation assembly 6 from moisture, corrosion, short circuit and other safety hazards. When the air-conditioning outdoor unit is in a non-rainy state, the controller controls the first shaft system assembly 201 to drive the water shield 1 to open the water shield 1, so that it is in a non-rainproof state, maintaining the normal heat dissipation operation of the heat dissipation assembly 6.
[0064] Optionally, in an implementation of this embodiment, as Figure 3 、 4 As shown,
[0065] The water shield 1 is rotatably arranged on the device installation side of the housing 5 and is opened and closed by rotating;
[0066] The shaft assembly further includes a second shaft assembly 202 , and the second shaft assembly 202 and the first shaft assembly 201 are respectively arranged at both ends of the water shield 1 ;
[0067] The electrical box assembly further includes a second detection assembly, which is arranged on the side of the second shaft assembly and is used to obtain the rotation angle information of the water shield 1 relative to the housing 5;
[0068] The second detection component is electrically connected to the controller, and the controller is further designed to control the first shaft system component 201 to drive the water shield 1 according to the rotation angle information of the water shield 1 obtained by the second detection component.
[0069] In this embodiment, the rotation angle information of the water shield 1 is obtained through the transmission connection between the second shaft system component 202 and the water shield 1, and the control data of the first shaft system component 201 is provided to the controller. When the rotation angle information of the water shield 1 obtained by the second shaft system component 202 is equal to the preset value, the controller controls the first shaft system component 201 to stop working and stop driving the water shield 1, so that the water shield 1 is closed or reset to open at the appropriate position, thereby realizing the precise closing or resetting of the water shield 1.
[0070] Optionally, in an implementation of this embodiment, as Figure 3 、 4 As shown,
[0071] The water shield 1 includes a vertically extending main body plate, a first side plate 101 connected to the lower end of the main body plate, and a second side plate 102 connected to the upper end of the main body plate. The first side plate 101 and the second side plate 102 are respectively folded from the main body plate toward the device installation side. When the water shield 1 is in a rainproof state, the second side plate 102 is located above the heat dissipation component 6, and the first side plate 101 is located below the heat dissipation component 6.
[0072] The first shaft assembly 201 includes a first rotating shaft 2011 rotatably disposed on the housing 5 and a motor for driving the first rotating shaft 2011 to rotate, wherein one end of the first rotating shaft 2011 is transmission-connected to the output end of the motor, and the other end is transmission-connected to the first side plate 101 to drive the water shield 1 to rotate;
[0073] The second shaft system assembly 202 includes a second rotating shaft 2021 rotatably arranged on the shell 5 and transmission-connected to the second side plate 102, and a fixed seat 2023 for supporting the second rotating shaft 2021, wherein the second rotating shaft 2021 is rotationally connected to the fixed seat 2023; the axis center line of the second rotating shaft 2021 is coaxial with the axis center line of the first rotating shaft 2011.
[0074] In this embodiment, the water shield 1 is driven to rotate by the first shaft system component 201, and the water shield 1 is opened or closed in a rotating manner. The rotation angle information of the water shield 1 is obtained by the second shaft system component 202 and the water shield 1 through transmission connection. The data of the degree of opening or closing is the rotation angle of the water shield 1. That is, when the rotation angle value of the water shield 1 obtained by the second shaft system component 202 is equal to the preset value, the controller controls the first shaft system component 201 to stop working and stop driving the water shield 1, so that the water shield 1 is closed or reset to open at the appropriate position, and the water shield 1 is accurately closed or reset to open. The shaft system component drives the water shield 1 to rotate and can record the rotation angle of the water shield 1 at the same time. The first shaft system component 201 and the second shaft system component 202 in the shaft system component are respectively located at the lower end and the upper end of the water shield 1. The structure is simple and can serve as the rotating shaft of the water shield 1 and can also achieve accurate driving of the water shield 1.
[0075] Specifically, the first detection component is arranged on the outer wall surface of the water shield;
[0076] And / or, the second detection component includes a grating component, the grating component includes a scale grating 2022 and a grating reading head 2024, wherein the scale grating 2022 is arranged on the second rotating shaft 2021 for detecting the rotation angle information of the water shield 1 relative to the shell 5, and the grating reading head 2024 is arranged on the fixed seat 2023 for reading the rotation angle information of the scale grating 2022.
[0077] In this embodiment, the setting of the first side plate 101 and the second side plate 102 makes the rotation of the water shield 1 more stable, and the setting of the first side plate 101 and the second side plate 102 facilitates the connection between the shaft system assembly and the water shield 1. The motor drives the first rotating shaft 2011 to rotate, and the first rotating shaft 2011 rotates, driving the first side plate 101 to rotate, and the water shield 1 rotates accordingly to perform opening and closing movements. The first rotating shaft 2011 and the second rotating shaft 2021 are set to be coaxial. Then, during the rotation process, the water shield 1 drives the second rotating shaft 2021 to rotate. The rotation of the second rotating shaft 2021 will synchronously drive the scale grating 2022 to rotate. The grating reading head 2024 can read the rotation angle of the scale grating 2022 and feed it back to the controller, so that when the rotation angle value of the water shield 1 obtained by the second shaft system assembly 202 is equal to the preset value, the controller controls the first shaft system assembly 201 to stop working and stop driving the water shield 1, so that the water shield 1 is closed or reset to open at the appropriate position.
[0078] Among them, the first rotating shaft 2011 and the second rotating shaft 2021 are set to be coaxial, that is, the axes of the first rotating shaft 2011 and the second rotating shaft 2021 coincide and can rotate synchronously. One end of the first rotating shaft 2011 is connected to the output end of the motor by bolts, and the other end is connected to the first side plate 101 by bolts. The motor provides power for the closing and opening of the water shield 1, and the second rotating shaft 2021 is also connected to the second side plate 102 by bolts.
[0079] When the water shield 1 is in a rainproof state, the second side plate 102 is located above the heat dissipation component 6, and the first side plate 101 is located below the heat dissipation component 6. This position design can keep the heat dissipation airflow unobstructed in the shell 5 without being blocked by the side plates.
[0080] Preferably, the first side plate 101 is provided with an air hole. Further preferably, the first side plate 101 forms a downward protrusion, and the bottom of the protrusion is formed with an air hole to facilitate the downward air flow or downward air flow, thereby further reducing wind resistance.
[0081] The first detection component is a raindrop sensor. The first detection component is in a continuous working state. When rain falls, the first detection component transmits a rain signal to the controller. The controller controls the first shaft system component 201 to drive the water shield 1 to rotate and close, and is in a rainproof state. The falling rain is blocked by the water shield 1 and is difficult to penetrate into the interior of the components that need to be protected from rain.
[0082] Optionally, in an implementation of this embodiment, as Figure 3 、 4 As shown,
[0083] The main body panel is provided with a shutter 3, which is provided with a plurality of shutters, each shutter having a top end connected to the main body panel and a bottom end protruding outward from the main body panel and forming a ventilation gap with the main body panel;
[0084] The top view projection of the bottom end of each hundred leaves is located outside the top view projection of the top end of each hundred leaves.
[0085] In this embodiment, the main plate in the water shield 1 is a plate structure, and the plate structure is in a rainproof state in the closed state, which can fully block rain and prevent rainwater from intruding. The first detection component is a raindrop sensor, and the first detection component is in a continuous working state. When rain falls, the first detection component transmits the rain signal to the controller, and the controller controls the first axis system component 201 to drive the water shield 1 to rotate and close, and is in a rainproof state. The falling rainwater is difficult to invade the interior of the components that need to be protected from rain under the blocking effect of the water shield 1. The rainwater falls on the blinds 3. The blinds on the blinds 3 protrude outward and have openings facing the bottom, which can divert rainwater away from the ventilation holes to prevent rainwater from entering through the ventilation holes. The setting of the ventilation holes can meet the heat dissipation needs of the components, and even in the rainproof state, the environment in which the components are located can keep ventilated and heat-dissipated.
[0086] Optionally, in an implementation of this embodiment, as Figure 1 、 2 As shown,
[0087] The housing 5 is provided with a baffle 7 on the device installation side thereof and the baffle 7 is provided above the heat dissipation assembly 6;
[0088] The fan assembly includes a first fan assembly 8 , which is disposed on the second side plate 102 and has an air inlet spaced apart from the baffle 7 ;
[0089] When the water shield 1 is in the rainproof state, the baffle 7 blocks the top of the first fan assembly 8 .
[0090] In this embodiment, the baffle 7 is slightly higher than the heat dissipation assembly 6. When the electrical box assembly is exposed to rain, raindrops fall on the baffle 7, and the baffle 7 acts as an "umbrella" for the heat dissipation assembly 6. There can be multiple heat dissipation assemblies 6. For example, if there are two heat dissipation assemblies 6, the two heat dissipation assemblies 6 are arranged vertically in the housing 5, and a partition 12 is provided between the two heat dissipation assemblies 6. The partition 12 supports the middle position of the water shield 1 in the closed state, thereby preventing the water shield 1 from collapsing due to external forces. Preferably, a plurality of through holes are provided on the partition 12 to maintain unobstructed heat dissipation airflow in the housing 5.
[0091] When the wind direction is complex, raindrops will bypass the baffle 7 and drop onto the heat dissipation assembly 6, which may easily cause adverse consequences such as short circuit and corrosion of the electrical components of the electrical box. When the water shield 1 is in a closed state, it can prevent raindrops from invading the housing 5, thereby effectively preventing the heat dissipation assembly 6 from being eroded by rainwater. The first fan assembly 8 starts working, forming an airflow trend of side air intake and top air outlet in the housing 5. There is a certain distance between the first fan assembly 8 and the baffle 7, which will not hinder the outflow of airflow, and assist in heat dissipation of the heat dissipation assembly 6. When the water shield 1 is in the open reset open state, the first fan assembly 8 stops working. When the water shield 1 is in a closed state, the baffle 7 completely covers the first fan assembly 8 to prevent rainwater from bypassing the baffle 7 and dripping from the first fan assembly 8 to prevent the heat dissipation assembly 6 from being soaked. The water shield 1 can be automatically closed and opened through the shaft structure. It can be automatically closed on rainy days to protect the heat dissipation component 6 in the electrical box from being affected by rain. At the same time, a first fan component 8 is provided to assist the heat dissipation of the heat dissipation component 6. The water shield 1 automatically opens on non-rainy days and the first fan component 8 stops working to avoid ineffective work, thereby achieving energy saving and life extension of the first fan component 8 itself.
[0092] Optionally, in an implementation of this embodiment, as Figure 1 、 2 As shown,
[0093] The fan assembly further includes a fan bracket 9 and a second fan assembly 11 disposed inside the fan bracket 9. When the water shield 1 is in the rainproof state, the second fan assembly 11 is located above the first side plate 101 and an air inlet of the second fan assembly 11 is spaced apart from the first side plate 101.
[0094] The second fan assembly 11 and the first fan assembly 8 are configured to have the same airflow outlet direction.
[0095] Furthermore, the fan bracket 9 is formed with a stopper 10 on one side facing the water shield 1. The stopper 10 is configured to prevent the water shield 1 from rotating when the water shield 1 rotates to a preset angle when the water shield 1 is transformed from a non-rainproof state to a rainproof state.
[0096] The motor is a DC torque motor, and the motor is equipped with a third detection component for detecting torque changes of the motor;
[0097] The third detection component is electrically connected to the controller. When the rotation of the water shield 1 is blocked by the blocker 10, the third detection component can obtain the torque feedback value of the motor;
[0098] The controller is also designed to control whether the DC torque motor stops rotating according to whether the torque feedback value reaches a preset torque value.
[0099] In this embodiment, the setting of the second fan assembly 11 further increases the heat dissipation capacity of the fan assembly. The setting of the fan bracket 9 can not only fix the second fan assembly 11, but also cooperate with the DC torque motor and the third detection assembly. When the rotation angle value of the water shield 1 obtained by the second shaft system assembly 202 is equal to the preset value, the controller controls the first shaft system assembly 201 to stop working. On this basis, the water shield 1 is accurately closed or reset to open. A third torque detection assembly is added. When the water shield 1 is in contact with the barrier 10, that is, the water shield 1 is in a closed state, the third detection assembly can obtain the torque feedback value of the water shield 1. When the controller determines that the torque feedback value reaches the preset torque value, it controls the DC torque motor to stop working, further ensuring that the water shield 1 is accurately closed.
[0100] The cooling fan frame in the first fan assembly 8 is fixed to the second side plate 102 by bolts, and the cooling fan in the second fan assembly 11 is fixed to the inner side of the fan bracket 9 by bolts. The second fan assembly 11 and the first fan assembly 8 are configured to have the same airflow direction, so that the second fan assembly 11 and the first fan assembly 8 can jointly assist in cooling the heat dissipation assembly 6.
[0101] The first fan assembly 8 and the second fan assembly 11 are both electrically connected to the controller in the electrical box assembly. The controller is also designed as follows: when the water shield 1 in the electrical box assembly is in a rainproof state, the first fan assembly 8 and the second fan assembly 11 are both controlled to be turned on; when the water shield 1 in the electrical box assembly is in a non-rainproof state, the first fan assembly 8 and the second fan assembly 11 are both controlled to be stopped.
[0102] The water shield 1 is automatically closed and opened through the shaft structure. It can be automatically closed on rainy days to protect the heat dissipation component 6 in the electrical box from being affected by rain. At the same time, the first fan component 8 and the second fan component 11 are provided to assist in heat dissipation of the heat dissipation component 6. The water shield 1 is automatically opened on non-rainy days and the first fan component 8 and the second fan component 11 stop working to avoid ineffective work, thereby achieving energy saving and life extension of the first fan component 8 and the second fan component 11 themselves.
[0103] Example 2
[0104] like Figure 1-4 As shown, this embodiment provides an air conditioner outdoor unit, including: a shell 4 and the electrical box assembly of the first embodiment arranged in the shell 4.
[0105] The existing top-outlet type room air-conditioning outdoor unit's electrical box heat dissipation assembly only uses a water retaining bracket to protect the heat dissipation assembly from rain. However, when the environmental wind direction is relatively complex, raindrops will bypass the water retaining bracket and drip onto the heat dissipation assembly, which can easily cause adverse consequences such as short circuit and corrosion of the electrical components of the electrical box. In the air-conditioning outdoor unit of this embodiment, the water retaining cover 1 of the electrical box assembly is rotatably connected to the opening of the shell 5, that is, the water retaining cover 1 is equivalent to the door of the shell 5. By designing the shaft system assembly, the water retaining cover 1 can be opened or closed under the drive of the first shaft system assembly 201. The open state of the water retaining cover 1 is a non-rainproof state. At this time, there is no rain falling in the external environment, and the electrical box assembly as a whole is in a non-rainproof state, which does not affect the normal heat dissipation work of the heat dissipation assembly 6; when there is rain falling in the external environment, the water retaining cover 1 is driven by the first shaft system assembly 201 and is converted from an open state to a closed state. It is converted from a non-rainproof state to a rainproof state, which effectively protects the heat dissipation component 6 from rain and avoids safety hazards such as moisture, corrosion, and short circuit. The shaft system component realizes automatic closing and resetting of the water shield 1. It can automatically close on rainy days to protect the heat dissipation component 6 from being affected by rain, and automatically reset and open on sunny days without affecting the normal heat dissipation of the heat dissipation component 6. When the water shield 1 is opened or closed, the second shaft system component 202 is connected to the water shield 1 through a transmission connection to obtain the rotation angle information of the water shield 1, and provides the controller with control data for the first shaft system component 201. When the rotation angle information of the water shield 1 obtained by the second shaft system component 202 is equal to the preset value, the controller controls the first shaft system component 201 to stop working and stop driving the water shield 1, so that the water shield 1 is closed or reset and opened at the appropriate position, and the water shield 1 is accurately closed or reset and opened.
[0106] Example 3
[0107] like Figure 6 As shown, this embodiment provides a control method, which is used to control the electrical appliance box in the second embodiment.
[0108] Specifically, obtaining and determining whether the electrical box is in a rainy environment;
[0109] If so, the first shaft assembly 201 is controlled to drive the water shield 1 to rotate and close, and the rotation angle value of the water shield 1 is obtained. When the rotation angle value of the water shield 1 reaches a first preset value, the first shaft assembly 201 is controlled to stop driving the water shield 1 to rotate, and the first fan assembly 8 and the second fan assembly 11 are controlled to work;
[0110] If not, control the first shaft system component 201 to drive the water shield 1 to rotate and open, obtain the rotation angle value of the water shield 1, and when the rotation angle value of the water shield 1 reaches the second preset value, control the first shaft system component 201 to stop driving the water shield 1 to rotate, and control the first fan component 8 and the second fan component 11 to stop working.
[0111] The above control method can automatically close and reset the water shield 1 accurately, effectively protect the heat dissipation component 6 from rain, and can be opened in time on sunny days without affecting the normal heat dissipation work of the heat dissipation component.
[0112] In summary, the ingenious design of the electrical box assembly lies in:
[0113] First, by setting the fan assembly and the water shield to be linked, the water shield is converted from an open state to a closed state, that is, from a non-rainproof state to a rainproof state, which effectively protects the heat dissipation assembly from rain, avoids it from moisture, corrosion, short circuit and other safety hazards, and affects the electrical components inside. When the water shield is in the closed state, the fan assembly starts working at the same time to assist the heat dissipation of the heat dissipation assembly. When the water shield is in the open state, the fan assembly stops working, so that the electrical box assembly can have a good heat dissipation effect even in the rainproof state. The water shield automatically opens on non-rainy days and the fan assembly stops working at the same time, avoiding ineffective work and achieving energy saving and life extension of the fan assembly itself.
[0114] Second, by designing the shaft system assembly, the water shield can be opened or closed under the drive of the first shaft system assembly, which effectively protects the components that need to be protected from rain. The shaft system assembly realizes automatic closing and resetting of the water shield. It can automatically close on rainy days to protect the components that need to be protected from rain from being affected by rain, and automatically reset and open on sunny days without affecting the normal operation of the components that need to be protected from rain. The rotation angle information of the water shield is obtained through the transmission connection between the second shaft system assembly and the water shield, and the controller is provided with control data of the first shaft system assembly, so that the water shield can be closed or reset and opened at the appropriate position, realizing precise closing or resetting and opening of the water shield.
[0115] Third, the first rotating shaft and the second rotating shaft are set to be coaxial. During the rotation of the water shield, the second rotating shaft is driven to rotate. The rotation of the second rotating shaft will synchronously drive the grating to rotate. The grating reading head in the grating cooperates with the grating scale to read the angle of grating rotation and feed back to the controller, so that when the rotation angle value of the water shield obtained by the second axis system component is equal to the preset value, the controller controls the first axis system component to stop working and stop driving the water shield, so that the water shield is closed or reset to open in the appropriate position. The axis system component has a simple structure and precise control.
[0116] Fourth, the electrical box assembly realizes automatic closing and opening of the water shield through the shaft structure. It can automatically close on rainy days to protect the heat dissipation components in the electrical box from being affected by rain. At the same time, the first fan assembly and the second fan assembly are provided to jointly assist in heat dissipation of the heat dissipation components to avoid the closure of the water shield affecting the heat dissipation of the heat dissipation components. The water shield automatically opens on non-rainy days and the first fan assembly and the second fan assembly both stop working to avoid ineffective work, thereby achieving energy saving and life extension of the first fan assembly and the second fan assembly themselves.
