The invention provides an air conditioner, which is provided with a shell 10, wherein the shell 10 is an outer shell of the air conditioner and is used for forming a space for installing functional components inside the air conditioner. The housing 10 is formed with an air inlet for inlet air and an air outlet 12 for outlet air. Fig. 1 to 10 are drawings corresponding to embodiments of the present invention.
Referring to fig. 1, 2 and 3, in one embodiment, the air conditioner further includes:
a water receiving tray 20, disposed in the housing 10, for receiving condensed water; the water receiving tray 20 has a concave water containing area, and the water receiving tray 20 is used for receiving condensed water generated in the air conditioner.
An antibacterial case 30 installed in the housing 10 for accommodating an antibacterial agent; the antimicrobial agent may be provided in granular, powdered or other form within the antimicrobial box 30. The antibacterial case 30 is used for accommodating an antibacterial agent so that the antibacterial agent can be accommodated in a preset manner. The antibacterial agent can be silver nitrate or other materials with bactericidal performance.
A driving device 50 installed in the housing 10, the driving device 50 being connected to the antimicrobial box 30; the driving device 50 is in driving connection with the antibacterial box 30, and is used for driving the antibacterial box 30, so that the antibacterial box 30 can release, reduce release and even stop releasing the antibacterial agent under the driving of the driving device 50.
An electric control box 40 arranged in the shell 10, wherein the electric control box 40 is electrically connected with the driving device 50; the electronic control box 40 is provided with a controller, and the electronic control box 40 can acquire the operation state of the air conditioner and can send a driving signal to the driving device 50.
Referring to fig. 4 and 5, when the electronic control box 40 detects that the air conditioner is in a standby or off state, a first control signal is sent to the driving device 50, and after the driving device 50 receives the first control signal, the antibacterial box 30 is driven to release the antibacterial agent to the water pan 20.
The antibacterial agent is released from the antibacterial box 30, and the antibacterial box 30 may be wholly or partially immersed in the condensed water in the water pan 20, so that the condensed water enters the antibacterial box 30, the antibacterial box 30 is dissolved in the condensed water, and the dissolved antibacterial agent enters the water pan 20 through the antibacterial box 30.
The antimicrobial box 30 releases the antimicrobial agent, or the driving device 50 may drive the antimicrobial box 30 to be opened locally, for example, the box cover 32 of the antimicrobial box 30 is opened, so that the antimicrobial agent is scattered from the antimicrobial box 30 into the water pan 20.
The antibacterial agent is released from the antibacterial box 30, or the driving device 50 may drive the antibacterial box 30 to rotate, so that the antibacterial agent falls into the water pan 20 from the opening of the antibacterial box 30.
When the electronic control box 40 detects that the air conditioner is in a starting state, a second control signal is sent to the driving device 50, so that the antibacterial agent is reduced or stopped from being released by the antibacterial box 30.
When the antibacterial box 30 is wholly or partially immersed in the condensed water of the water pan 20, the driving device 50 drives the antibacterial box 30 to be removed from the condensed water of the water pan 20 when receiving the second control signal, and at this time, the antibacterial box 30 stops releasing the antibacterial agent. When the height of the antibacterial case 30 is raised so that the depth of the antibacterial case 30 sunk into the condensed water is reduced, the antibacterial agent dissolved in the condensed water is reduced, and thus the amount of released antibacterial agent can be reduced.
When the antimicrobial box 30 releases the antimicrobial agent in a partially opened manner, the driving means 50 drives the antimicrobial box 30 to be closed when receiving the second control signal so that the antimicrobial agent cannot be scattered from the antimicrobial box 30 or partially closes the antimicrobial box 30 to reduce the amount of the antimicrobial agent scattered from the antimicrobial box 30.
When the antimicrobial box 30 releases the antimicrobial agent in a rotating manner, the driving device 50 drives the antimicrobial box 30 to restore the original position after receiving the second control signal, so that the antimicrobial agent cannot drop from the antimicrobial box 30, or the rotation angle of the antimicrobial box 30 is reduced, so that the amount of the antimicrobial agent scattered from the antimicrobial box 30 is reduced.
The air conditioner may also include other functional components such as a fan, a heat exchanger 11, a water pump 60, and a valve assembly. Since water droplets in the air flow are easily condensed on the heat exchanger 11 to form condensed water when the air conditioner is operated, the water receiving tray 20 may be disposed below the heat exchanger 11 to receive the condensed water dropped on the heat exchanger 11.
Referring to fig. 6, in order to prevent water return during the air conditioner operation, a water return bend is connected to the outside of the water pan 20, so that a portion of condensed water remains in the water pan 20 during the shutdown or standby of the air conditioner. Optionally, the air conditioner further includes a water pump 60, and the water pump 60 is used for pumping out the condensed water in the water pan 20. When the air conditioner is in the running state, condensed water generated by the air conditioner can be accumulated in the water receiving disc 20, so that the water level of the water receiving disc 20 is increased, the water in the water receiving disc 20 is pumped out by the water pump 60 when the air conditioner is in the starting state, and when the air conditioner is in the standby state or the shutdown state, the water level in the water receiving disc is lower than the water level when the air conditioner is in the normal running state, and the water pump 60 can stop running. By reducing or stopping the release of the antimicrobial agent when the air conditioner is on standby or off, it is possible to prevent the antimicrobial agent from being drawn into the water pump 60 when the air conditioner is running, thereby preventing the water pump 60 from clogging. Through setting up suction pump 60, can be the level setting with water collector 20, need not slope the water collector, and then can reduce the space that water collector 20 occupy, promote air conditioner inner space utilization.
When the air conditioner is in a shutdown state, the antibacterial box 30 releases antibacterial agent, and after the antibacterial agent enters the water pan 20, the condensed water in the water pan 20 is sterilized, so that bacteria in the condensed water are removed, and bacteria breeding is avoided. When the air conditioner is in a shutdown state, the electric control box 40 sends the first control signal to the driving device 50, and after the driving device 50 drives the antibacterial box 30 to release the antibacterial agent, the residual condensed water in the water receiving tray 20 is sterilized, so that when the air conditioner is in a shutdown or standby state and no high-speed airflow flows in the air conditioner, bacteria breeding in the water receiving tray 20 is reduced. When the air conditioner is in operation, high-speed air flow is generated, the tiny mixture carried by the air flow is attached to the surface of the heat exchanger through the flow of the air flow, and when the air conditioner is in refrigeration operation, the heat exchanger of the air conditioner is flushed due to the generation of condensed water, the mixture is brought into the water receiving disc, and the mixed condensed water entering the water receiving disc is discharged outside the air conditioner under the action of the water pump, so that the sterilization operation is not performed or the sterilization intensity is reduced under the refrigeration state of the air conditioner. In the internal heating state, no condensed water exists, the inside of the machine body in the heating state is a dry environment, and bacteria are slowly bred, so that the sterilization operation is not performed or the sterilization intensity is reduced in the starting state of the air conditioner. When the air conditioner is provided with the water pump 60, the water pump 60 is usually started in the on state of the air conditioner and is closed in the off state, so that the water pump 60 can pump out the condensed water in the water receiving disc 20 in the on state of the air conditioner, and bacteria are not easy to grow in the water receiving disc 20. If the antimicrobial box 30 does not release the antimicrobial agent in the on state, the antimicrobial agent is not consumed at all in the on state; if the antibacterial agent is released in the starting state, the antibacterial box 30 can rapidly sterilize the condensed water entering the water pan 20, and then the condensed water is pumped out by the water pump 60, so that the consumption of the antibacterial agent in the antibacterial box 30 is reduced, and the water pump 60 can be connected with a water return bend, so that bacteria breeding at the water return bend can be reduced.
When the water pan 20 is arranged below the heat exchanger 11, the water pan 20 receives condensed water dropped by the heat exchanger 11, and because the air conditioner runs, high-speed air flows in the air conditioner, under the action of the fan, the high-speed air flows have a trend of flowing in a direction close to the lower end face of the air outlet 12, so that the air flow close to one side of the water pan 20 is large. When the antibacterial agent is released from the antibacterial box 30 in the on state, the consumption speed of the antibacterial agent in the antibacterial box 30 is greatly increased along with the air flow flowing at a high speed, so in the embodiment, when the air conditioner is in the on state, the release of the antibacterial agent is reduced or stopped, so that the high-speed air flow does not affect the antibacterial agent, the antibacterial agent is not easily blown out from the housing 10 along with the air flow, and the consumption of the antibacterial agent is further reduced. When the antibacterial agent is dissolved in the condensed water, a small amount of condensed water may be driven to flow to a side of the water pan 20 near the air outlet due to the high flow of the air conditioner. Therefore, in this embodiment, the antibacterial agent is released only when the air conditioner is in the off or standby state, so as to reduce the influence on the air volume of the air conditioner, and meanwhile, the operation noise of the air conditioner is reduced, and the use experience of the air conditioner is improved.
The antibacterial agent released from the antibacterial case 30 may be directly released into the condensed water of the water pan 20, or may be released to a designated position of the water pan 20.
Alternatively, the water pan 20 may have a drain hole 21, and the antimicrobial box 30 may be disposed near the drain hole 21. When the water receiving tray 20 is inclined at a certain angle, part of accumulated water in the water receiving tray 20 can be discharged through the water discharge hole 21. The antimicrobial box 30 releases the antimicrobial agent to a position near the drain hole 21 to sterilize the accumulated water in the drip tray 20. The antibacterial case 30 may be disposed on a side wall of the water receiving tray 20 at a side where the drain hole 21 is located, so that the antibacterial case 30 can rapidly release the antibacterial agent into the accumulated water.
When the air conditioner is provided with the water pump 60, the water pump 60 may be disposed close to the drain hole 21 to pump out the accumulated water in the water receiving tray 20. Since the air conditioner is sterilized when in the off or standby state, the bacteria content in the water pan 20 is reduced, so that the pollution to the water pump 60 can be reduced, and the cleanliness of the air conditioner pipeline is improved.
The electric control box 40 may be disposed near the water receiving tray 20, and the electric control box 40, the driving device 50, the water pump 60 and the valve assembly of the air conditioner may be disposed on the same side of the casing 10, so as to facilitate wiring and maintenance.
Referring to fig. 7 and 8, in an embodiment, the driving device 50 includes a motor 51 and a lifting rod 52 drivingly connected to the motor 51, and the motor 51 may be disposed on a side wall of the water pan 20 or may be disposed on the housing 10 of the air conditioner. The lifting rod 52 is connected with the antibacterial box 30, and when the motor 51 drives the lifting rod 52 to move relatively, the antibacterial box 30 moves synchronously. The lifting rod 52 may be in a vertical lifting state or may rotate relatively to realize lifting of the antibacterial box 30. As shown in fig. 8, the motor 51 may drive a gear to rotate, a tooth surface is disposed on the lifting rod 52, and the gear is engaged with a gear rack of the lifting rod 52, or engaged with the gear rack, so as to implement directional movement of the lifting rod 52.
In an embodiment, when the electronic control box 40 detects that the air conditioner is in the standby state or the off state, after a second preset period of time of the first control signal is sent to the driving device 50, the second control signal is sent to the driving device 50, so that the antimicrobial box 30 reduces or stops releasing the antimicrobial. The electronic control box 40 obtains the duration of sending the first control signal to the driving device 50, and when the duration of sending the first control signal to the driving device 50 reaches the second preset duration, the second control signal is sent to the driving device 50, so that whether the air conditioner enters a starting state or not is not required to be detected. The second preset duration may be 2 minutes, or 3 minutes, or other preset duration after the electronic control box 40 sends the first control signal to the driving device 50, and within the second preset duration, the antibacterial box 30 releases the antibacterial agent into the water pan 20, so as to be used for sterilizing the condensed water. After the electronic control box 40 sends the first control signal to the driving device 50 for the second preset time period, the electronic control box 40 may directly send the second control signal to the driving device 50 without detecting whether the air conditioner is started, so that the antimicrobial box 30 stops releasing the antimicrobial agent. In this embodiment, the time when the electronic control box 40 sends the first control signal may be any time when the air conditioner is in the shutdown or standby state.
Because the height of the backwater bay of the air conditioner is not determined by engineering installation, the accumulated water in the water pan of the air conditioner is also different after the air conditioner is standby or stopped, and the water level of the water pan can be detected by a liquid level switch. The second preset time period is a time period required for the antimicrobial box 30 to release enough antimicrobial into the antimicrobial box 30. The second preset time period is adapted to the remaining amount of the antibacterial agent in the antibacterial box 30 and the type of the antibacterial agent, and takes the case that the antibacterial agent is dissolved in water by partially immersing the antibacterial box 30 in condensed water as an example, when the remaining amount of the antibacterial agent in the antibacterial box 30 is more or the water solubility of the antibacterial agent is higher, the second preset time period can be relatively shorter, when the remaining amount of the antibacterial agent in the antibacterial box 30 is less or the water solubility of the antibacterial agent is poorer, the second preset time period can be relatively longer, and the second preset time period is adjusted by the remaining amount or the water solubility of the antibacterial agent, so that the use of the antibacterial agent is more reasonable, and the consumption speed of the antibacterial agent is reduced. The electronic control box 40 may record the time for replacing the antibacterial agent, and when the antibacterial agent is replaced by the antibacterial box 30, the second preset time period may be correspondingly shortened when the amount of the antibacterial agent is large, and may be gradually shortened as the time for replacing the antibacterial agent last time is prolonged. The electronic control box 40 may preset a correspondence between the second preset duration and the type of the selected antimicrobial agent, and shorten the second preset duration when the selected antimicrobial agent has high water solubility. And when the water solubility of the selected antibacterial agent is low, prolonging the second preset time period.
By setting the second preset time period, the time period for releasing the antibacterial agent, which is sufficient to reduce the bacteria content in the water pan 20 to a preset level, can be set as needed. Since the preset sterilizing effect can be achieved within the second preset time period, the antibacterial box 30 is not required to continuously release the antibacterial agent, and further, the waste of the antibacterial agent can be avoided on the premise of meeting the sterilizing requirement, so that the consumption speed of the antibacterial agent is reduced.
The second preset time period may be related to the amount of condensed water in the water-receiving tray 20, and may be relatively extended when the depth of the condensed water in the water-receiving tray 20 is large, and may be relatively shortened when the amount of condensed water in the water-receiving tray 20 is small.
When the air conditioner is in a standby or shutdown state, the depth of the antibacterial box 30 extending into the condensed water is related to the amount of the condensed water, when the condensed water is more, the distance of the antibacterial box 30 entering into the condensed water is larger, and when the condensed water is less, the distance of the antibacterial box 30 entering into the condensed water is smaller. The distance refers to the depth at which the antimicrobial box 30 extends below the level of the condensate.
In another embodiment, when the electronic control box 40 detects that the air conditioner starts to enter a standby state or a shutdown state, that is, the driving device 50 sends the first control signal, and after a second preset time period of sending the first control signal, sends the second control signal to the driving device 50. When the electronic control box 40 detects that the air conditioner is turned off or standby, the driving device 50 drives the antibacterial box 30 to release the antibacterial agent to the water pan 20, and the timing starting point of the second preset duration is the time when the air conditioner enters the off or standby state. By detecting that the air conditioner enters a standby or shutdown state, the electric control box 40 controls the driving device 50 to drive the antibacterial box 30 to release the antibacterial agent, when the air conditioner stops running, no high-speed air flow flows in the air conditioner, and the condensed water in the water receiving disc 20 starts to grow bacteria. The antimicrobial box 30 starts to release the antimicrobial agent under the drive of the drive device 50, i.e. the initial content of bacteria is reduced, and the bacterial growth is further reduced. Since the initial content of bacteria in the water tray 20 is reduced, the problem of an increase in the content of bacteria in the air conditioner case 10 due to an increase in the content of bacteria in the water tray 20 before the antibacterial agent is released from the antibacterial agent case 30 can be avoided, and the spread of bacteria can be effectively reduced. The setting of the second preset duration is the same as that in the previous embodiment, and will not be described again.
Referring to fig. 4, 5 and 7, in one embodiment, the air conditioner further includes: when the electronic control box 40 sends the first control signal to the driving device 50, the driving device 50 drives the antibacterial box 30 to be at least partially below the water level of the condensed water in the water receiving tray 20, the antibacterial agent is dissolved in the condensed water, and the antibacterial box 30 can directly abut against the bottom surface of the water receiving tray 20, so that the antibacterial agent in the antibacterial box 30 is dissolved in the condensed water. Taking the driving mode of the motor 51 driving the lifting rod 52 as an example in fig. 7, the motor 51 receives the first control signal, and the motor 51 operates to drive the lifting rod 52 to descend until the antibacterial box 30 is at least partially located in the condensed water, and the antibacterial agent in the antibacterial box 30 is dissolved in the condensed water, so as to realize the sterilization operation. The descending height of the antibacterial box 30 may be related to the type of the antibacterial agent and the water solubility thereof, when the antibacterial agent has good water solubility, the antibacterial box 30 may be partially located in the condensed water, and when the antibacterial agent has poor water solubility, the antibacterial box 30 may be integrally located below the liquid surface of the condensed water to accelerate the dissolution of the antibacterial agent. The lowered height of the antimicrobial box 30 may also be related to the remaining amount of antimicrobial in the antimicrobial box 30. When the electronic control box 40 sends the second control signal to the driving device 50, the driving device 50 drives the antibacterial box 30 to move upwards out of the liquid level of the condensed water in the water receiving tray 20. After the antimicrobial box 30 is removed from the drip tray 20, the release of antimicrobial agent is stopped. Taking the structure shown in fig. 7 and 8 as an example, the motor 51 drives the lifting rod 52 to move upwards, so that the antimicrobial box 30 is moved out from the liquid surface in the water receiving tray 20.
