As shown in fig. 1 to 6, in order to solve the problem of low control precision of the automatic opening of the sterilization device of the conventional air conditioner, the ceiling type air conditioner (hereinafter, referred to as air conditioner) of the present application mainly includes a body 1, a detection assembly, a sterilization assembly and a controller 4, wherein the specific composition of the detection assembly is described below, and the sterilization assembly is not specifically shown in the drawings. An air inlet 11 and an air outlet 12 are arranged on the body 1, an air inlet grille is arranged at the air inlet 11, an air deflector 2 is arranged at the air outlet 12, a heat exchanger and a fan (not shown in the figure) are arranged in the body 1, and two end covers 13 are respectively arranged at two ends of the body 1 along the length direction. The detection assembly comprises a light source emitting end 31, a light source receiving end 32 and a light transmitting element 33, wherein the light source emitting end 31 is arranged in the body 1, the light source receiving end 32 can emit light, the light source receiving end 32 can receive the light emitted by the light source emitting end 31, and the light transmitting element 33 is arranged on a light transmission path between the light source emitting end 31 and the light source receiving end 32. The sterilization component is arranged in the body 1, and can sterilize air flowing through the body 1 when being opened. The controller 4 is arranged in the body 1, the controller 4 is respectively connected with the detection assembly and the sterilization assembly, and the controller 4 is arranged to control the sterilization assembly to be opened or closed according to the intensity of the light received by the light source receiving end 32.

In the operation process of the ceiling type air conditioner, indoor air enters the body 1 from the air inlet 11 under the driving of the fan, and is sent back to the indoor from the air outlet 12 after exchanging heat with the heat exchanger. The light source emitting end 31 emits light, and the light passes through the light transmitting element 33 and is received by the light source receiving end 32. When the indoor air is good, dust mites and bacteria in the air are less, and the probability that the light-transmitting member 33 is covered by the dust mites and bacteria is less, substantially all the light emitted from the light source emitting end 31 is received by the light source receiving end 32. When the indoor air contains more dust mites and bacteria, the probability that the surface of the light-transmitting element 33 is covered by the dust mites and the bacteria is higher, and the light emitted by the light source emitting end 31 is partially shielded by the light-transmitting element 33, so that the intensity of the light received by the light source receiving end 32 is weakened. At this time, the controller 4 controls the sterilization assembly to start to operate, and performs sterilization and disinfection on the air flowing through the body 1 so as to reduce the content of dust mites and bacteria in the air.

As can be seen from the above description, the start-stop control precision of the sterilization assembly can be greatly improved by arranging the detection assembly in the air conditioner, the sterilization effect is ensured, and the energy is saved. Specifically, the detecting assembly includes a light source emitting end 31, a light source receiving end 32 and a light transmitting element 33 disposed on a light transmission path therebetween, in a normal condition, light emitted from the light source emitting end 31 passes through the light transmitting element 33 and is received by the light source receiving end 32, and the intensity of light received by the light source receiving end 32 is slightly attenuated. When dust mite, bacterium, virus etc. are more in the air, the part can cover on printing opacity component 33, the light intensity that light source receiving end 32 received this moment will attenuate to some extent, after attenuating to a certain extent, can regard dust mite in the air, bacterium and virus are more, need carry out the degerming disinfection to the room air, the control subassembly operation of disinfecting this moment, can guarantee the sterile promptness of disinfecting, guarantee to disinfect the subassembly in case open just in time effectively, and also be favorable to improving the disinfection effect of disinfecting, energy saving.

A preferred embodiment of the air conditioner of the present application will now be described with further reference to fig. 1 and 6.

Referring to fig. 1, in a preferred embodiment, the air inlet 11 is disposed on an upper surface of the body 1 (in the direction shown in fig. 1, the same applies below) in an extending manner along a length direction of the body 1, and an air inlet grille is disposed on the upper surface and extends along the length direction of the body 1. The air outlet 12 extends along the length direction of the body 1 and is arranged on an arc-shaped transition surface between the upper surface and the front side surface, the air deflector 2 is provided with a first driving mechanism (not shown in the figure), the first driving mechanism is connected with the controller 4, and the controller 4 can control the first driving mechanism to act, so that the air deflector 2 is driven by the first driving mechanism to rotate relative to the air outlet 12. The first driving mechanism can be a motor or a combination of the motor and a gear, when the first driving mechanism is the motor, an output shaft of the motor is directly connected with the air deflector 2 so as to drive the air deflector 2 to rotate, and when the first driving mechanism is the combination of the motor and the gear, the motor drives the air deflector 2 to rotate through the gear. The driving method of the above wind deflector 2 is a common means in the art, and is not described herein again. In addition, a plurality of swing blades 5 are further disposed inside the air outlet 12, the swing blades 5 are configured with a second driving mechanism, and the swing blades 5 are driven by the second driving mechanism to swing left and right, for example, a combination of a motor and a transmission rod is used as the second driving mechanism.

Referring to fig. 2-3 and 5-6, the light source emitting end 31 is an infrared light emitter, the light source receiving end 32 is an infrared light sensor, and the light source emitting end 31 and the light source receiving end 32 are respectively disposed on inner walls of two end portions of the air outlet 12 along the length direction, and are opposite to each other, so that the infrared light source emitted from the light source emitting end 31 is transmitted along a straight line and received by the light source receiving end 32. The light-transmitting element 33 is an infrared filter, and is disposed at one end of the air outlet 12 along the length direction and close to the inner wall of the light source receiving end 32 through the pillar 331, and after the light-transmitting element is disposed, the infrared filter is located in front of the light source receiving end 32 (i.e., on the right side of the light source receiving end 32 shown in fig. 6), and can filter most light waves except infrared light.

Referring to fig. 2 and 5, the detecting assembly further includes a wireless transmitting module 34 connected to the light source receiving end 32, and the controller 4 is further connected to a wireless receiving module 41, wherein the wireless transmitting module 34 can be communicatively connected to the wireless receiving module 41. Specifically, the wireless transmitting module 34 is a WiFi transmitting module, which is disposed on the outer wall of the end where the light source receiving end 32 is located, and is in signal connection with the light source receiving end 32. The wireless receiving module 41 is a WiFi receiving module, and is disposed on the outer wall of the end where the light source emitting end 31 is located together with the controller 4.

In one possible embodiment, after the infrared emitter emits infrared light with a set wavelength, the infrared light passes through the infrared filter and is received by the infrared sensor, and the infrared sensor may output different sensing values according to the intensity of the received infrared light, where the sensing values are generally electrical signals, such as sensing voltage or sensing current. The electrical signal is sent to the WiFi receiving module through the WiFi transmitting module, so that the controller 4 can acquire the electrical signal. Because the infrared filter is covered by dust mites and bacteria to different degrees, the electric signals obtained by the controller 4 are different, and the controller 4 can determine the intensity of infrared light based on the electric signals and further control the on-off of the sterilization component based on the intensity.

In an alternative embodiment, after the infrared emitter emits infrared light with a set wavelength, the infrared light passes through the infrared filter and is received by the infrared sensor, and the infrared sensor can output different sensing values according to the intensity of the received infrared light, where the sensing values are generally electric signals, such as sensing voltage or sensing current. Since the infrared filters are covered by dust mites and bacteria to different degrees, the electrical signals output by the infrared light sensors are different. The infrared light sensor can be connected with the comparator, the intensity of infrared light is judged through the comparator, the judgment result is sent to the WiFi receiving module through the WiFi transmitting module in a mode of sending an instruction signal, and after the controller 4 acquires the instruction signal, the on-off of the sterilization assembly can be controlled based on the instruction signal.

The sterilizing component is arranged at the air outlet 12, specifically an ultraviolet sterilizing lamp, the ultraviolet sterilizing lamp is connected with the controller 4, and starting and stopping are realized under the control of the controller 4. Specifically, when the intensity of the infrared light is judged to be small, it is proved that the infrared filter is partially covered by dust mites or bacteria at this time, and the sterilization assembly needs to be turned on. At this time, the controller 4 controls the sterilization assembly to operate to sterilize the air flowing through the body 1. On the contrary, when the intensity of the infrared light is judged to be larger, the infrared light is proved to be slightly attenuated after passing through the infrared filter, the number of dust mites and bacteria in the air is less, and the work of the sterilization assembly is not required to be controlled. At the moment, the state of the sterilization assembly is further judged, and if the sterilization assembly is in a closed state, the controller 4 controls the air conditioner to keep the current state; if the sterilizing module is in an on state, the controller 4 controls the sterilizing module to be turned off.

Although the specific number and the installation position of the sterilization units are not described in the present embodiment, it is not clear, and a person skilled in the art can adjust the installation position, the installation number, and the like of the sterilization units based on actual conditions. For example, the sterilizing assembly may include one, two or more ultraviolet sterilizing lamps, and when there is one, the ultraviolet sterilizing lamps may be disposed on an inner wall of any one end of the outlet 12 in the length direction and irradiate toward the other end; when two bactericidal lamps are provided, the bactericidal lamps can be simultaneously arranged on the inner wall of one end of the air outlet 12 along the length direction and irradiate towards the other end, or can be respectively arranged on the inner walls of the two ends of the air outlet 12 along the length direction and irradiate towards each other. Of course, in other embodiments, two uv germicidal lamps may be disposed in the middle of the outlet 12 and irradiate in opposite directions.

By using the infrared light emitter as the light source transmitting end 31 and the infrared light sensor as the light source receiving end 32, the infrared light emitted by the infrared light emitter can be received by the infrared light sensor after passing through the light-transmitting element 33, and then whether the sterilization component is started or not is judged according to the intensity of the infrared light received by the infrared light sensor, so that the sterilization timeliness is ensured, the sterilization component is ensured to be timely and effective once being started, and the energy conservation of the air conditioner is facilitated. Through setting up infrared light emitter and infrared light sensor respectively on the inner wall at air outlet 12 along length direction's both ends, can reduce the influence of the air-out of air outlet 12 to the testing result, this is because air outlet 12 is less along length direction's both ends wind speed when the air-out, and dust mite and bacterium stop here more easily. By arranging the wireless transmitting module 34 and the wireless receiving module 41 in the air conditioner, the wireless transmission of signals can be realized, the complex wiring between the detection assembly and the controller 4 is omitted, and the internal structure of the air conditioner is simplified. By using the infrared filter as the light-transmitting element 33, redundant light can be filtered, so that the infrared light sensor can only receive infrared light, and the detection and judgment precision is improved.

It should be noted that the above preferred embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention. The utility model discloses do not deviate under the prerequisite of principle, technical personnel in the field can adjust the mode of setting up to the aforesaid, so that the utility model discloses can be applicable to more specific application scene.

For example, in an alternative embodiment, although the light source emitting end 31 and the light source receiving end 32 are respectively disposed on the inner walls of the two ends of the air outlet 12 along the length direction and the light-transmitting element 33 is disposed on the inner wall close to the light source receiving end 32 in the above embodiment, the arrangement manner is not exclusive, and a person skilled in the art can adjust the arrangement position of the detection assembly as long as it can satisfy the condition that the light emitted from the light source emitting end 31 can pass through the light-transmitting element 33 and be received by the light source receiving end 32. For example, the light source emitting end 31 and the light source receiving end 32 may be respectively disposed on the inner walls of the two end portions of the air inlet 11 along the length direction; as another example, the light-transmitting member 33 may be provided on an inner wall near either one of the light source emitting end 31 or the light source receiving end 32. For another example, the light source emitting end 31, the light source receiving end 32 and the light transmitting element 33 are all disposed inside the upper surface (in the orientation shown in fig. 1) of the main body 1, so that when the air conditioner is installed in a suspended ceiling, the upper surface is located at the lowest side and faces indoors, and dust mites and bacteria in the indoor space are more easily detected under the action of gravity.

For another example, in another alternative embodiment, although the light source emitting end 31 and the light source connecting end are described above with reference to an infrared light emitter and an infrared light sensor, this is not intended to limit the scope of the present application, and in some other embodiments, the light source emitting end 31 may also be an ultraviolet light emitter, and the corresponding light source receiving end 32 may be an ultraviolet light sensor, etc. Of course, when the light source emitting end 31 is an infrared light emitter or an ultraviolet light emitter, the light source receiving end 32 may not only correspondingly select an infrared light sensor or an ultraviolet light sensor, but also a photosensitive element capable of receiving and sensing the intensity of light may be applied in the present application.

For another example, in another alternative embodiment, the type of the light-transmitting element 33 is not constant, and in some other embodiments, when the light source emitting end 31 uses an ultraviolet light emitter, the light-transmitting element 33 may be an ultraviolet filter, and a glass sheet or a plastic film without a filter layer may be used, which may be arbitrarily adjusted by a person skilled in the art as long as the light-transmitting element 33 can effectively achieve the conditions of light transmission and attachment by dust mites and bacteria.

For another example, in another alternative embodiment, although the position of the sterilization assembly is described with an ultraviolet sterilization lamp disposed at the air outlet 12, the arrangement may be adjusted by those skilled in the art, and any device capable of effectively sterilizing air may be applied to the present application. For example, the sterilization component may also be an infrared sterilization lamp, an anion generator, etc., and the sterilization component may be disposed inside the air inlet 11, the heat exchanger, etc. besides the air outlet 12.

For another example, in another alternative embodiment, although the present application simplifies the internal structure of the air conditioner by using the wireless transmitting module 34 and the wireless receiving module 41, it is obvious to those skilled in the art that a wired connection may be used instead of a wireless connection, and the modification of the connection does not require creative efforts. In addition, the wireless transmitting module 34 and the wireless receiving module 41 may be replaced by an infrared module, a bluetooth module, or the like, in addition to the WiFi module described above.

Of course, the above alternative embodiments, and the alternative embodiments and the preferred embodiments can also be used in a cross-matching manner, so that a new embodiment is combined to be suitable for a more specific application scenario.

Although not specifically described, the controller 4 of the air conditioner may be a controller provided in the air conditioner itself, may be a controller dedicated to executing the present invention, or may be a functional module or functional unit of another general-purpose controller.

Next, a method of controlling sterilization of an air conditioner according to the present application will be described with reference to fig. 7. Fig. 7 is a flowchart of a sterilization control method for an air conditioner according to the present invention.

As shown in fig. 7, corresponding to the above-mentioned structure of the ceiling type air conditioner, the present application also provides a sterilization control method of the ceiling type air conditioner, which mainly comprises the following steps:

s101, judging the intensity of light received by a light source receiving end and the size of a preset intensity threshold; for example, the infrared light sensor outputs different sensing values according to the intensity of received infrared light, and the sensing values are generally electric signals which are sent to the WiFi receiving module through the WiFi transmitting module, so that the electric signals are acquired by the controller as the intensity of the infrared light. The electrical signal may be an induced voltage, and the controller compares the voltage with a preset intensity threshold (i.e., a voltage threshold) after receiving the voltage.

S103, controlling the opening and closing of the sterilization component based on the judgment result; for example, when the induced voltage value is less than or equal to the voltage threshold value, the ultraviolet germicidal lamp is controlled to be started to sterilize the air flowing through the body; and when the induction voltage value is greater than the voltage threshold value, controlling the ultraviolet germicidal lamp to be turned off (if the ultraviolet germicidal lamp is turned on), or keeping the current running state of the air conditioner (if the ultraviolet germicidal lamp is not turned on).

Through the sterilization control method, the air conditioner realizes automatic control of the sterilization assembly, improves the start-stop control precision of the sterilization assembly, ensures the sterilization effect and saves energy. Specifically, the intensity of the received light is judged, and when the intensity is greater than a preset intensity threshold value, the intensity attenuation of the light received by the light source receiving end is small, the permeability of the light-transmitting element is good, the surface of the light-transmitting element is not covered by dust mites and bacteria, the side surface reflects that the bacteria in the indoor air are less, and therefore the sterilization assembly does not need to be started. When the intensity is smaller than or equal to the preset intensity threshold value, the intensity of light received by the light source receiving end is proved to be weakened, the light-transmitting element is covered by dust mites and bacteria, the sterilization assembly needs to be opened to sterilize indoors, so that the content of the dust mites and the bacteria in the air is reduced, the timeliness of sterilization is guaranteed, the sterilization assembly is guaranteed to be timely and effective once opened, and the energy saving of the air conditioner is facilitated.

A more preferred embodiment of the sterilization control method of the present application will be described below.

In a more preferred embodiment, the step S103 further includes:

when the intensity of light is less than or equal to the preset intensity threshold value, the sterilization assembly is controlled to work, and the air flowing through the body is sterilized. When the intensity of the light is greater than a preset intensity threshold value, further judging the working state of the sterilization assembly; if the sterilization component is in an opening state, controlling the sterilization component to be closed; and if the sterilizing component is in the closed state, controlling the air conditioner to keep the current running state.

For example, when the electric signal that infrared light sensor output is the voltage, when the magnitude of voltage is less than or equal to and predetermines intensity threshold value (predetermines the magnitude of voltage), prove that infrared filter part was sheltered from by dust mite and bacterium this moment, and the side reflects the bacterium quantity that contains in the room air too much, needs to carry out germicidal treatment to the room air, and the controller control ultraviolet germicidal lamp opened this moment to in time carry out germicidal treatment to the air that flows through the body effectively. On the contrary, if the voltage value is larger than the preset voltage value, the permeability of the infrared filter is better, the infrared filter is not shielded, the infrared light emitted by the infrared emitter is basically and completely received by the infrared sensor, the indoor air quality is better reflected by the side surface, and the sterilization treatment is not needed. At the moment, the running state of the ultraviolet germicidal lamp is further judged, and when the ultraviolet germicidal lamp is not started, the current running state of the air conditioner is only required to be kept; when the ultraviolet germicidal lamp is turned on, the ultraviolet germicidal lamp is controlled to be turned off so as to save electric energy.

In a preferred embodiment, when the air outlet is provided with an air deflector which is controlled by the controller to rotate, and the ultraviolet germicidal lamp is arranged at the air outlet, the sterilization control method further comprises:

and when the intensity of the light is less than or equal to the preset intensity threshold value, controlling the air deflector to be closed to a preset anti-irradiation angle. Still taking the electrical signal as an example of the voltage value, when the ceiling type air conditioner is installed, the lower surface of the air conditioner is fixed on the ceiling plate or the roof, the upper surface faces indoors (according to the direction shown in fig. 1), and the air deflector is located on the arc transition surface between the upper surface and the front side surface of the main body. When the air deflector is opened, a user can see partial structures in the body, when the ultraviolet sterilizing lamp is turned on, the possibility that the ultraviolet lamp irradiates a human body to damage the human body exists, and therefore when the voltage value is smaller than or equal to the preset voltage value, the air deflector is controlled to be closed to the preset irradiation-preventing angle. The anti-irradiation angle refers to an angle capable of blocking ultraviolet rays emitted by the ultraviolet germicidal lamp from directly irradiating a human body, for example, the air deflector is closed to a position which forms an angle of 30-45 degrees with the horizontal plane, and after the anti-irradiation angle is closed, the air conditioner can still normally wind out.

Through when the intensity of light is less than or equal to the preset intensity threshold value, the air deflector is controlled to be closed to the preset anti-irradiation angle, the sterilization control method can guarantee the air supply effect and the sterilization effect, and meanwhile, the sterilization assembly is prevented from hurting a human body when in operation.

In a possible implementation manner, when the wireless transmitting module is a WiFi transmitting module and the wireless receiving module is a WiFi receiving module, before step S101, the sterilization control method further includes:

through the communication connection between the WiFi transmitting module and the WiFi receiving module, the light source receiving end sends the intensity of the received light to the controller.

As such, step S101 further includes:

the controller judges the intensity of the light and the preset intensity threshold value.

For example, the infrared light sensor may output different sensing values according to the intensity of the received infrared light, where the sensing values are generally electrical signals, such as sensing voltage or sensing current. The electric signal is sent to the WiFi receiving module through the WiFi transmitting module, so that the controller can acquire the electric signal. Because the infrared filter is covered by dust mites and bacteria to different degrees, the electric signals obtained by the controller are different, the controller can determine the intensity of infrared light based on the comparison result of the electric signals and a preset intensity threshold value, and then the ultraviolet germicidal lamp is controlled to be turned on or off based on the intensity.

In an alternative embodiment, step S101 further comprises:

and the light source receiving end judges the intensity of the light and the size of a preset intensity threshold.

As such, step S103 further includes:

based on the judgment result, the light source receiving end sends a control signal to the controller; in response to the control signal, the controller controls the sterilization assembly to operate.

For example, the infrared light sensor may output different sensing values according to the intensity of the received infrared light, where the sensing values are generally electrical signals, such as sensing voltage or sensing current. Since the infrared filters are covered by dust mites and bacteria to different degrees, the electrical signals output by the infrared light sensors are different. The infrared light sensor can be connected with the comparator, the intensity of infrared light (namely the magnitude of induced voltage or induced current) is judged through the comparator, the judgment result is sent to the WiFi receiving module through the WiFi transmitting module in a mode of sending an instruction signal, and after the controller obtains the instruction signal, the controller can control the on-off of the ultraviolet germicidal lamp based on the instruction signal. For example, when the controller acquires a high level signal "1", the controller controls the ultraviolet germicidal lamp to be turned off; and when the controller acquires the low level signal '0', the controller controls the ultraviolet germicidal lamp to be started.

Of course, in other embodiments, the light source receiving end and the controller may be connected by a wire, and the control method after the wire connection has the same principle as the control method described above, and will not be described herein again.

For example, the step of judging the intensity of the light and the magnitude of the preset intensity threshold value and the step of judging whether the ultraviolet germicidal lamp is turned on can be exchanged; for example, the step of determining whether the ultraviolet germicidal lamp is on may be omitted.
