Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Referring to fig. 1 to 6, an embodiment of the present invention provides an air conditioner, which includes a housing 10, an auxiliary heater 30, and a controller 40. The evaporator 20 and the auxiliary heater 30 are both provided in the case 10. The controller 40 is signally connected to the supplemental heater 30.
Wherein, when the air conditioner enters the heating mode, the controller 40 can control the auxiliary heater 30 to perform auxiliary heating. When the air conditioner enters the sterilization mode, the controller 40 is configured to control the auxiliary heater 30 to be turned on, so that the auxiliary heater 30 can heat the surface of the evaporator 20, thereby sterilizing the air conditioner; acquiring a first temperature of the surface of the evaporator 20; if the first temperature reaches a first preset temperature, recording the first time after the first temperature reaches the first preset temperature; if the first time does not reach the first preset time, the operation is continued in a state that the first temperature reaches the first preset temperature.
In some embodiments, the sterilization method of the air conditioner includes steps S101 to S104.
And S101, controlling the auxiliary heater 30 to be turned on so that the auxiliary heater 30 can heat the surface of the evaporator 20.
S102, a first temperature of the surface of the evaporator 20 is obtained.
S103, if the first temperature reaches the first preset temperature, recording the first time lasting after the first temperature reaches the first preset temperature.
And S104, if the first time does not reach the first preset time, continuing to operate in a state that the first temperature reaches the first preset temperature.
The above embodiments provide an air conditioner and a sterilization method of the air conditioner, which can achieve sterilization by the auxiliary heater 30 of the air conditioner itself, without adding additional sterilization components, and reduce the manufacturing cost of the air conditioner. When the air conditioner enters the sterilization mode, the auxiliary heater 30 can generate heat to heat the surface of the evaporator 20, thereby destroying the living and breeding environment of bacteria and achieving the purpose of killing bacteria and purifying air. In addition, the air conditioner and the sterilization method of the air conditioner can sterilize the air conditioner without adding an additional sterilization part, so that wind resistance cannot be generated on the air conditioner, and the performance of the air conditioner is not influenced. The controller 40 controls the air conditioner to work, the temperature and/or time are accurately and flexibly controlled, the structure and the sterilization method are simple and convenient, and the control is ingenious.
In some embodiments, the controller 40 may be disposed integrally within the housing 10, or may be disposed outside the housing 10, which is not limited herein.
It will be appreciated that microorganisms typically have an optimum growth temperature range, growth temperature limits and a thermal death temperature. After the ambient temperature exceeds the growth temperature limit of the bacteria, the bacteria stop growing or even die. For example: the optimal growth temperature range of the mould is 25-30 ℃, and the growth temperature limit is 15-37 ℃; the optimal growth temperature range of the microzyme is 20-28 ℃, and the growth temperature limit is 10-35 ℃; the optimal growth temperature range of the microzyme is 35-40 ℃, and the growth temperature limit is 5-45 ℃. When the temperature of the environment where the microorganism is located exceeds the optimal growth range and is still within the growth temperature limit, the growth speed of the microorganism is slowed down. When the temperature of the environment where the microorganism is located exceeds the growth temperature limit, proteins, nucleic acids and the like constituting the cell are easily damaged, the cell function is reduced, and if the microorganism is located in the environment at a temperature outside the growth temperature limit for a long time, the cell constituting the microorganism is easily irreversibly damaged until the cell dies, and the microorganism dies.
Illustratively, the first preset temperature is a heat-induced death temperature of the microorganisms, when the ambient temperature reaches the heat-induced death temperature, the microorganisms are dead, and the death rate of the microorganisms becomes high along with the increase of time. The first temperature of the surface of the evaporator 20 is maintained at the first predetermined temperature for a first predetermined time to kill most of the pathogenic and non-pathogenic bacteria.
The specific values of the first preset temperature and the first preset time and the relation between the first preset temperature and the first preset time can be designed according to actual requirements. In some embodiments, the greater the first set temperature, the smaller the first set time, the faster the sterilization rate; the smaller the first set temperature is, the larger the first preset time is, and the slower the sterilization rate is. For example, when the first preset temperature is 50 ℃, the first preset time is 40 min. If the first predetermined temperature is 55 ℃, the first predetermined time is preferably 30 min to 35 min. The specific values of the first preset temperature and the first preset time are only exemplary, and the relationship between the first preset temperature and the first preset time is not limited to the above.
It is understood that in order to shorten the sterilization time and increase the sterilization rate, it is theoretically better that the first preset temperature is higher, but the heat generated by the auxiliary heater 30 cannot be increased infinitely due to the performance limitation of the air conditioner itself, for example, due to the limitation of the operation power of the auxiliary heater 30, and the first preset temperature of the surface of the heat exchanger in the indoor air conditioner is generally 50 ℃ to 65 ℃.
In some embodiments, the first set time is 15 min to 60 min. The air conditioner is mainly used for adjusting indoor temperature. When the air conditioner is switched from the normal mode to the sterilization mode, the effect of the air conditioner on the indoor temperature regulation is affected. The longer the sterilization mode is continued, the greater the influence on the indoor temperature. If the duration of the sterilization mode is too short, effective sterilization cannot be performed. The normal mode includes a heating mode, a cooling mode, and the like.
In some embodiments, the supplemental heater 30 is disposed below the evaporator 20 to enable heat generated by the supplemental heater 30 to be transferred to the surface of the evaporator 20. Specifically, after the auxiliary heater 30 is turned on, the auxiliary heater 30 generates heat and transfers the generated heat to the air in the air conditioner, and the air expands, becomes larger in volume and smaller in density when heated, so that the heated air flows upward. When the upward flowing hot air flows to the evaporator 20, the hot air can exchange heat with the surface of the evaporator 20, and the heat in the air is transferred to the surface of the evaporator 20, so that the auxiliary heater 30 heats the surface of the evaporator 20.
In some embodiments, the auxiliary heater 30 includes at least one of a ceramic PTC heater, a heating wire heating pipe, a metal PTC heater, and a metal heater.
In some embodiments, the air conditioner further includes a first temperature sensor 50. The first temperature sensor 50 is provided on the surface of the evaporator 20. The first temperature sensor 50 is in signal connection with the controller 40, and is used for detecting the first temperature and feeding the first temperature back to the controller 40.
In some embodiments, obtaining a first temperature of a surface of evaporator 20 comprises: a first temperature of the surface of the evaporator 20 is acquired by the first temperature sensor 50. Specifically, the first temperature sensor 50 detects a first temperature of the surface of the evaporator 20 and feeds back the first temperature to the controller 40, so that the controller 40 controls the air conditioner to perform sterilization according to the first temperature.
In some embodiments, the housing 10 has an air duct (not labeled) and an air outlet 11 in communication with the air duct. The air conditioner further includes a motor 60 and a wind wheel 70. The motor 60 is disposed in the housing 10, and the motor 60 is in signal connection with the controller 40. The wind wheel 70 is arranged in the air duct, and the wind wheel 70 is in transmission connection with the motor 60. When the air conditioner enters the sterilization mode, the controller 40 can control the motor 60 to drive the wind wheel 70 to rotate, thereby sterilizing the air conditioner. When the motor 60 and the wind wheel 70 work, the air in the air duct can be driven or accelerated to flow towards the preset direction, so that the heating effect of the auxiliary heater 30 on at least one of the surface of the evaporator 20, the wind wheel 70 and the air duct is improved, and the sterilization efficiency of the air conditioner is further improved.
Illustratively, the evaporator 20 is disposed within the air duct.
In some embodiments, the controller 40 can control the motor 60 to rotate forward, so that the heat generated by the auxiliary heater 30 can be transferred to the surface of the evaporator 20 at a higher speed, and the heating effect of the auxiliary heater 30 on the surface of the evaporator 20 is improved, thereby improving the sterilization efficiency of the air conditioner.
In some embodiments, the controller 40 can control the motor 60 to rotate reversely, so that the heat generated by the auxiliary heater 30 can be transferred on the surface of the wind wheel 70 and/or in the air duct at an increased speed, the heating effect of the auxiliary heater 30 on at least one of the wind wheel 70 and/or the air duct is improved, the survival and propagation of bacteria on the wind wheel 70 and/or the air duct are destroyed, and the purpose of killing the bacteria on the wind wheel 70 and/or the air duct is achieved.
In some embodiments, the auxiliary heater 30 is disposed between the evaporator 20 and the wind wheel 70. When the motor 60 is not operated or the motor 60 is rotated reversely, the heat generated from the auxiliary heater 30 is collected upward through the air in the air conditioner, thereby heating the surface of the evaporator 20. When the motor 60 rotates forward, the heat generated by the auxiliary heater 30 can be transferred on the surface of the wind wheel 70 and/or in the air duct at an increased speed, and the auxiliary heater 30 can heat the surface of the wind wheel 70 and/or the air duct, so as to sterilize the surface of the wind wheel 70 and/or the air duct.
In some embodiments, the air conditioner further includes a wind guide vane 80. The wind guide 80 is rotatably disposed on the housing 10 to open or close the wind outlet 11. The controller 40 can control the rotation position of the air guide blade 80 to adjust the opening size of the air outlet 11 of the casing 10, thereby adjusting the temperature in the air conditioner.
In some embodiments, the housing 10 includes a face frame 12 and a chassis 13. The air outlet 11 is arranged on the face frame 12. The chassis 13 is provided in the face frame 12. The chassis 13 and the face frame 12 cooperate to form an air duct.
In some embodiments, the wind rotor 70 is mounted to the chassis 13. The evaporator 20 is mounted on the chassis 13 by means of a snap connection or the like. The chassis 13 is mounted on the face frame 12. The auxiliary heater 30 is mounted on the evaporator 20 by screws or the like. The motor 60 is arranged on the chassis 13 and is in transmission connection with the wind wheel 70.
In some embodiments, the air conditioner further includes a second temperature sensor 90 for sensing the ambient temperature. The second temperature sensor 90 is in signal communication with the controller 40. The second temperature sensor 90 detects the second temperature and feeds the second temperature back to the controller 40. The second temperature sensor 90 may be provided at any suitable position of the air conditioner as long as it can detect the ambient temperature. For example, the second temperature sensor 90 is disposed at an air inlet of the housing 10.
In some embodiments, the sterilization method further includes adjusting the first temperature of the surface of evaporator 20 if the first temperature does not reach the first predetermined temperature. Specifically, adjusting the first temperature of the surface of evaporator 20 includes increasing the first temperature of the surface of evaporator 20 and decreasing the first temperature of the surface of evaporator 20. When the air conditioner is just in the sterilization mode, the first temperature is lower than the first preset temperature, and the first temperature on the surface of the evaporator 20 needs to be increased. When the first temperature reaches the first preset temperature, the first temperature needs to be kept at the first preset temperature. During the adjustment of the first temperature, the first temperature generally fluctuates above and below a first predetermined temperature, and it is necessary to lower the first temperature on the surface of the evaporator 20 or raise the first temperature on the surface of the evaporator 20 according to actual conditions. If the first temperature is greater than the first set temperature, the first temperature of the surface of the evaporator 20 is decreased. If the first temperature is less than the first predetermined temperature, the first temperature of the surface of the evaporator 20 is increased.
It should be noted that, in the process of entering the sterilization mode, the first temperature reaches the first set temperature, which means that the absolute value of the first temperature difference is smaller than the preset difference. Illustratively, the predetermined difference is 0-2 ℃, i.e., 0, 2 ℃ and any other suitable value of 0-2 ℃.
In some embodiments, adjusting the first temperature of the surface of the evaporator 20 includes: acquiring a first temperature difference between a first temperature and a first preset temperature; a first temperature of the surface of the evaporator 20 is adjusted based on the first temperature difference. The first temperature on the surface of the evaporator 20 is adjusted according to the first temperature difference, so that the air conditioner can be accurately controlled to sterilize.
In some embodiments, adjusting the first temperature of the surface of evaporator 20 based on the first temperature difference comprises: the operating power of the auxiliary heater 30 is adjusted according to the first temperature difference. The higher the operating power of the supplementary heater 30, the greater the first temperature of the surface of the evaporator 20. In adjusting the operating power of the supplementary heater 30 according to the first temperature difference, thereby adjusting the first temperature of the surface of the evaporator 20, the greater the first temperature difference is, the faster the operating power of the air conditioner is changed; the smaller the first temperature difference is, the slower the operating power of the air conditioner is changed
In some embodiments, adjusting the first temperature of the surface of evaporator 20 based on the first temperature difference comprises: according to the first temperature difference, the rotation position of the air guide blade 80 is adjusted to adjust the opening size of the air outlet 11 of the housing 10.
Specifically, the larger the first temperature difference is, the smaller the opening size of the outlet port 11 is. The smaller the first temperature difference is, the larger the opening size of the outlet port 11 is.
In some embodiments, adjusting the first temperature of the surface of evaporator 20 based on the first temperature difference includes adjusting an operating condition of motor 60 based on the first temperature difference, the operating condition including a rotational speed and/or a rotational direction of motor 60.
It will be appreciated that the first temperature of the surface of evaporator 20 may be adjusted by controlling the speed and/or direction of rotation of motor 60 based on the first temperature differential.
For example, the greater the first temperature difference, the greater the rotational speed of the motor 60. The smaller the first temperature difference, the smaller the rotation speed of the motor 60.
For another example, the greater the first temperature difference, the greater the speed of the motor 60. The smaller the first temperature difference is, the motor 60 is not operated or the motor 60 rotates at a rotational speed lower than the preset rotational speed.
For example, after the air conditioner enters the sterilization mode, the auxiliary heater 30 is turned on, the motor 60 is turned on, the controller 40 controls the motor 60 to rotate forward or backward, the air duct fluid is helpful for transferring the heat generated by the auxiliary heater 30, and the heat generated by the auxiliary heater 30 can be gathered upward (i.e., toward the evaporator 20) or downward, so as to sterilize or disinfect at least one of the evaporator 20, the wind wheel 70, the chassis 13, and the like in the air duct.
For example, after the air conditioner enters the sterilization mode, the auxiliary heater 30 is turned on, the motor 60 is turned on, the controller 40 controls the motor 60 to rotate forward or backward, the duct fluid is helpful to transfer the heat generated by the auxiliary heater 30, and the heat generated by the auxiliary heater 30 may be collected upward (i.e., toward the evaporator 20) or downward. The rotation speed of the motor 60 is adjusted using the first temperature fed back by the first temperature sensor 50. The speed of the heat generated by the auxiliary heater 30 is adjusted by the speed of the motor 60. Specifically, the faster the speed of the motor 60, the faster the heat transfer. The smaller the rotation speed of the motor 60 is, the smaller the heat transfer is, thereby controlling the temperature in the air conditioner and sterilizing and killing viruses.
For example, after the air conditioner enters the sterilization mode, the auxiliary heater 30 is turned on, the motor 60 is turned on, the controller 40 controls the motor 60 to rotate forward or backward, the duct fluid is helpful to transfer the heat generated by the auxiliary heater 30, and the heat generated by the auxiliary heater 30 may be collected upward (i.e., toward the evaporator 20) or downward. The first temperature fed back from the first temperature sensor 50 is used to adjust the operating power of the auxiliary heater 30, thereby adjusting the first temperature on the surface of the evaporator 20 and performing sterilization and virus killing.
In some embodiments, after controller 40 receives the sterilization command, auxiliary heater 30 is turned on, motor 60 is turned on, and controller 40 controls motor 60 to rotate in reverse to collect heat generated by auxiliary heater 30 to the surface of evaporator 20 to sterilize the surface of evaporator 20, and in particular to kill bacteria growing in evaporator 20. After the evaporator 20 is sterilized, the rotation direction of the motor 60 may be adjusted, and the heat generated by the auxiliary heater 30 is collected and accumulated on at least one of the wind channel, the wind wheel 70 and the chassis 13, thereby sterilizing and killing viruses on at least one of the wind wheel 70, the wind channel and the chassis 13.
In some embodiments, when the air conditioner enters the heating mode and a preset on condition is satisfied, the controller 40 controls the auxiliary heater 30 to perform auxiliary heating.
For example, when the air conditioner enters the heating mode, if the outdoor ambient temperature is lower than the set threshold value for the set time, the controller 40 controls the auxiliary heater 30 to be turned on to perform auxiliary heating on the air conditioner. For example, when the air conditioner enters the heating mode, if the outdoor ambient temperature is lower than the set threshold for 10 seconds, the controller 40 controls the auxiliary heater 30 to be turned on to perform auxiliary heating on the air conditioner.
Illustratively, when the air conditioner enters the heating mode, if the compressor and the motor 60 of the air conditioner are both turned on, the controller 40 controls the auxiliary heater 30 to be turned on to perform auxiliary heating on the air conditioner.
For example, when the air conditioner enters the heating mode, if the difference between the outdoor ambient temperature and the set threshold is less than or equal to the first set difference, the controller 40 controls the auxiliary heater 30 to be turned on to perform auxiliary heating on the air conditioner. For example, when the air conditioner enters the heating mode, if the difference between the outdoor ambient temperature and the setting is less than or equal to-3 ℃, the controller 40 controls the auxiliary heater 30 to be turned on to perform auxiliary heating on the air conditioner.
For example, when the air conditioner enters the heating mode, if the tube temperature of the evaporator 20 is less than the first preset tube temperature, the controller 40 controls the auxiliary heater 30 to be turned on to perform auxiliary heating on the air conditioner. For example, when the air conditioner enters the heating mode, if the temperature of the evaporator 20 is less than 48 ℃, the controller 40 controls the auxiliary heater 30 to be turned on to perform auxiliary heating on the air conditioner.
In some embodiments, the controller 40 controls the supplementary heater 30 to be turned off when the air conditioner enters the heating mode and a preset off condition is satisfied.
For example, after the air conditioner enters the heating mode, if the controller 40 receives a turn-off signal transmitted from a remote controller, the controller 40 controls the auxiliary heater 30 to be turned off.
Illustratively, when the air conditioner enters the heating mode, if the difference between the outdoor ambient temperature and the set threshold value is greater than or equal to the second set difference value for a preset duration, the controller 40 controls the auxiliary heater 30 to be turned off. For example, when the air conditioner enters the heating mode, if the difference between the outdoor ambient temperature and the second set difference is greater than or equal to 2 ℃ for 10 seconds, the controller 40 controls the auxiliary heater 30 to be turned off.
Illustratively, when the air conditioner enters the heating mode, the controller 40 controls the auxiliary heater 30 to be turned off if the difference between the outdoor ambient temperature and the set threshold is greater than or equal to a third set difference. For example, when the air conditioner enters the heating mode, if the difference between the outdoor ambient temperature and the third set difference is greater than or equal to-1 ℃, the controller 40 controls the auxiliary heater 30 to be turned off.
For example, when the air conditioner enters the heating mode, if the tube temperature of the evaporator 20 is greater than or equal to the second preset tube temperature, the controller 40 controls the auxiliary heater 30 to be turned on to perform auxiliary heating on the air conditioner. For example, when the air conditioner enters the heating mode, if the tube temperature of the evaporator 20 is greater than or equal to 52 ℃, the controller 40 controls the auxiliary heater 30 to turn off the heat.
Illustratively, when the air conditioner enters the heating mode, the controller 40 controls the auxiliary heater 30 to be turned off if at least one of the compressor and the motor 60 of the air conditioner is not operated.
For example, after the air conditioner enters the heating mode, if the air conditioner exits the heating mode, the controller 40 controls the auxiliary heater 30 to be turned off.
For example, when the air conditioner enters the defrosting mode after the air conditioner enters the heating mode, the controller 40 controls the auxiliary heater 30 to be turned off.
In some embodiments, when the air conditioner enters the sterilization mode, the controller 40 controls the auxiliary heater 30 to be turned on, so that the auxiliary heater 30 can heat the surface of the evaporator 20, thereby sterilizing the air conditioner.
