However, when the device is used as a module of a large air treatment device (such as an air conditioner or a fresh air treatment system), the device is usually installed inside the air treatment device, a user cannot directly observe the water amount of the water container, and when the water amount of the water container is too small, the situation that the user cannot add water timely to cause the device to work effectively or the phenomenon that the water is added too much is easy to occur.
The following describes a preferred technical scheme of the air treatment device and the air conditioner in the embodiment of the invention.
Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of an air treatment device according to an embodiment of the present disclosure, and fig. 2 is an exploded schematic diagram of an air treatment device according to an embodiment of the present disclosure. The embodiment provides an air treatment device 100, fan casing 4 has set gradually from bottom to top, water tank base 2, water container 1 and air-out casing 3, fan casing 4 internally mounted has fan 5, fan casing 4 and water tank base 2 fastening connection, 1 holding of water container is on water tank base 2, the top of water container 1 is equipped with the air outlet, air-out casing 3 covers in the air outlet department of water container 1 and is connected with the top of water container 1, 1 internally mounted of water container has water treatment spare 6. Wherein, an air inlet duct positioned at the upstream of the water container 1 is formed on the water tank base 2 and is communicated with an air inlet of the water container 1; an air outlet duct located at the downstream of the water container 1 is formed on the air outlet casing 3 and is communicated with an air outlet of the water container 1.
The water container 1 is used for containing water; the water treatment part 6 arranged in the water container 1 lifts or atomizes water, so as to purify, humidify or cool the air in the water container 1; the fan 5 positioned in the fan shell 4 is used for sending air in the environment into the water container 1 through the air inlet channel for treatment and sending the air after water treatment out from the air outlet channel. The fan 5 includes a motor 51 and fan blades 52, a motor shaft of the motor 51 is in transmission connection with the fan blades 52, and the motor shaft drives the fan blades 52 to rotate so that the air in the environment flows from the opening at the bottom of the fan housing 4 to the inside of the fan housing 4.
Based on the above, the water tank base 2, the inner space of the water container 1 and the air outlet housing 3 together form a flow channel for purifying air. When the air treatment device 100 works, the fan 5 is started to draw air (e.g., indoor air) in the external environment into the water tank base 2, i.e., into the air inlet duct, then the air passes through the internal space of the water container 1, is purified, humidified and/or cooled by the water mist or the water curtain formed by the water treatment member 6, enters the air outlet housing 3 from the top end of the water container 1, i.e., into the air outlet duct, and then is discharged into the external environment (e.g., flows back into the room) from one or more air outlets of the air outlet housing 3.
The air treatment device 100 further comprises a water adding flow passage, one end of the water adding flow passage is communicated with the water container 1, and the other end of the water adding flow passage extends out of the air treatment device 100 so as to add water into the water container 1. When the air treatment device 100 works for a period of time and water needs to be replenished to the water container 1, a user can directly add water to the water container 1 through the water adding flow passage. Therefore, the water container 1 does not need to be detached from the device for adding water, the procedure of detaching the water container 1 is omitted, and the water adding operation is convenient. Especially, when the device is used as a module of large-scale air treatment equipment (such as an air conditioner or a fresh air treatment system), a large amount of disassembly work is saved, the water adding operation is convenient, and the water adding efficiency is high.
FIG. 3 is a schematic view of a connection between a water container and a base of a water tank in an air treatment device according to an embodiment of the disclosure under a first vision. For example, as shown in fig. 1 to 3, a water guide 7 is installed on the tank base 2, a water adding flow passage communicated with the water container 1 is formed on the water guide 7, and at least a portion of the water guide 7 extends out of the tank base 2.
FIG. 4 is a schematic view of a water container and a water tank base connected under a second vision in an air treatment device according to an embodiment of the disclosure. In order to obtain the amount of water in the water container 1, as shown in fig. 4, the air treatment device 100 of the present embodiment further includes an upper limit water level detection device, a lower limit water level detection device 8, a processor and an alarm, wherein the upper limit water level detection device and the lower limit water level detection device 8 are vertically and alternately arranged in the water container 1, and the processor is electrically connected to the upper limit water level detection device, the lower limit water level detection device 8 and the alarm.
Wherein, the upper limit water level detection device is used for detecting the upper limit water level of the water container 1, and the lower limit water level detection device 8 is used for detecting the lower limit water level of the water container 1. Here, the upper limit water level refers to the highest water level value that can be allowed by the water container 1, the lower limit water level refers to the lowest water level value that can be allowed by the water container 1, and the upper limit water level and the lower limit water level can be reasonably set according to the capacity of the water container 1, which is not limited in this embodiment. For example, the water container 1 having a length of 1m, a width of 1m and a height of 1m has a volume of 1m3The upper limit water level may be 0.8m, and the lower limit water level may be 0.2 m.
The lower limit water level detection device 8 and the upper limit water level detection device both transmit the detected water level value to the processor, and the processor responds to the water level value and controls the alarm to send out an alarm signal. Specifically, when the water level of the water container 1 detected by the lower limit water level detection device 8 is lower than the lower limit water level, the processor controls the alarm to send out a water shortage alarm signal; when the water level of the water container 1 detected by the upper limit water level detection device is higher than the upper limit water level, the processor controls the alarm to send a full water alarm signal.
The disposer is disposed outside the water container 1, and may be attached to the outer wall of the water container 1, or may be disposed on the water tank base 2, the fan housing 4, or other components of the air treatment device 100. The processor receives the water level value detected by the lower limit water level detection device 8, compares the water level value with a preset lower limit water level, and controls the alarm to send out a water shortage alarm signal when the water level value is smaller than the lower limit water level. The processor may be a single chip or a Programmable Logic Controller (PLC), and this embodiment does not limit this.
The water shortage alarm signal and the water full alarm signal can be at least one of a light signal, a sound signal and a character signal, and the alarm can be different according to different types of the alarm signals. For example, when an alarm is made by using an acoustic signal, the alarm may be a buzzer or a speaker. Specifically, taking a loudspeaker as an example, the water shortage alarm signal may be a prompt sound of "please add water when the water amount is low" sent by the loudspeaker, and the water full alarm signal may be a prompt sound of "please stop adding water" sent by the loudspeaker; taking a buzzer as an example, the water shortage alarm signal can be that the buzzer sends out an alarm sound for 5 seconds, and the water full alarm signal can be that the buzzer sends out an alarm sound for 1 second.
For example, when the Light signal is used to alarm, the alarm may be a Light Emitting Diode (LED), a bulb, or an infrared emitter. Specifically, taking the LED lamp as an example, the water shortage alarm signal may be that the LED lamp flashes for 5 times, and the water full alarm signal may be that the LED lamp continuously emits light for 2 seconds. Of course, in some other examples of the present disclosure, the LED lamp may also prompt the water container 1 to reach the water-short state or the water-full state by emitting light of different colors. For example, the water shortage alarm signal may be that the LED lamp emits red light, and the water full alarm signal may be that the LED lamp emits yellow light.
When the alarm is given by using the text signal, the alarm can be a display device, such as an LED screen. Wherein, the LED screen can show "lack of water" word and come as lack of water alarm signal, and the LED screen can show "full water" word and come as full water alarm signal.
The alarm devices in the above embodiments may be mounted on the air treatment device 100, and when the air treatment device 100 is applied to a large air treatment apparatus, the alarm devices may also be mounted on the air treatment apparatus. For example, the air processing device is an air conditioner, the alarm can be installed on a panel of the air conditioner, and particularly when the alarm signal is a text signal, the text signal on the panel is easy to observe by a user.
In summary, in the air treatment device 100 provided in this embodiment, when the lower limit water level detection device 8 detects that the water level of the water container 1 is lower than the lower limit water level, the processor controls the alarm to send a water shortage alarm signal, so as to prompt the user to add water, so as to prevent the air treatment device 100 from being unable to work normally due to water shortage of the water container 1; when the upper limit water level detection device detects that the water level of the water container 1 is higher than the upper limit water level, the processor controls the alarm to send a full water alarm signal, so that the phenomenon that the water in the water container 1 exceeds the load due to excessive water adding is avoided.
Fig. 5 is a first schematic structural diagram of a water container in an air treatment device according to an embodiment of the disclosure, fig. 6 is a partially enlarged view of a portion a in fig. 5, and fig. 7 is a second schematic structural diagram of a water container in an air treatment device according to an embodiment of the disclosure. Referring to fig. 5 to 7, the lower limit water level detecting means 8 may include a magnetic field detecting means 81, a float 82, and a magnet, the float 82 being located inside the water container 1, the position of which changes according to the change of the water level, the magnet being provided on the float 82 and also changing according to the water level, the magnetic field detecting means 81 being provided on the outer wall of the water container 1 and outputting a voltage signal in response to the magnet. Therefore, compared with the detection of the lower limit water level of the water container 1 by the liquid level detection device, the water curtain is not easily formed because the water container 1 occupies too much space by the lower limit water level detection device 8.
When the air treatment device 100 works, the water amount in the water container 1 is gradually reduced, the floater 82 gradually descends, the position of the magnet relative to the magnetic field detection device 81 is changed, that is, the relative position between the magnet and the magnetic field detection device 81 is changed, the voltage signal output by the magnetic field detection device 81 is changed, the position of the magnet can be obtained by analyzing the voltage signal, and then whether the height of the liquid level of the floater 82 is lower than the lower limit water level or not can be judged, that is, whether the water level of the water container 1 is lower than the lower limit water level or not can be judged.
The magnetic field detection device 81 may be a magnetic field sensor, such as a GMR sensor, which has high sensitivity to a magnetic field and can convert a weak magnetic signal into an electrical signal; the magnetic field detection device 81 may also be a hall sensor, and the structures and operating principles of the GMR sensor and the hall sensor may be referred to in textbooks or technical manuals, which are not described herein again. Preferably, the height of the magnetic field detection device 81 from the bottom wall of the water container 1 is the same as the lower limit water level. When the float 82 floats to the lower limit water level, the magnetic field intensity detected by the magnetic field detection device 81 is the maximum, and the output voltage signal is the maximum, so that the float 82 can be known to be at the lower limit water level through the waveform of the output voltage signal, that is, the water level of the water container 1 is the lower limit water level.
The float 82 may be made of sponge, foam, or lightweight plastic, as long as it has a density less than that of water. The shape of the float 82 is not limited to a rectangle, and may be a regular or irregular shape such as a circle, a diamond, a square, or an ellipse. Preferably, the magnet is arranged at the edge position of the floater 82 close to the magnetic field detection device 81, and the measurement effect is good. The float 82 may be adhesively secured to the float 82 or may be attached to the float 82 by other intermediary means.
Further, the lower limit water level detecting means 8 further comprises a fixing portion which is fixedly coupled to the inner wall of the water container 1 and which is mounted on the float 82 to prevent the float 82 from rotating about the axis in the vertical direction and to restrict the float 82 from moving in the horizontal direction. Therefore, the fixed part limits the rotation and the movement in the horizontal direction of the floater 82, that is, the floater 82 can only move in the up-and-down direction, which is beneficial to preventing the horizontal distance between the magnet and the magnetic field detection device 81 from changing due to the rotation of the floater 82 along with the water flow or the movement in the horizontal direction, and is beneficial to preventing the output voltage signal from changing due to the interference of the magnetic field detection device 81, and the detection is more accurate. This arrangement is particularly suitable for use where the water treatment member 6 is a centrifugal slinger which, by rotating to lift water, tends to rotate the float 82 with the amount of water being rotated.
In one example, the fixing portion may include a fixing case with an open bottom, the bottom of the fixing case is connected to the bottom wall of the water container 1 through a connecting member, and the float 82 is located in the fixing case and can move in the up-and-down direction; and, there is a space between the bottom of the stationary box and the bottom wall of the water container 1 for the water to flow into the stationary box to float the float 82, which is smaller than the height of the float 82, so that the float 82 cannot leave the stationary box from the space. In this example, when the float 82 floats into abutment with the top wall of the cassette, the float 82 moves to a maximum height. Wherein the shape and size of the cassette can be designed appropriately according to the shape and size of the float 82, respectively. For example, where the float 82 is rectangular, the holding box may be rectangular or circular, with the size of the holding box being slightly larger than the float 82 so that the float 82 can only move up and down within the holding box.
Fig. 8 is a schematic structural diagram of a housing in an air processing device according to an embodiment of the disclosure. In another example, as shown in fig. 5 to 8, the fixing portion may also include a cover 83, and the cover 83 is tightly covered on the float 82; one side of the outer wall of the housing 83 is rotatably connected with a first connecting rod 831, the other side of the outer wall of the housing 83 is rotatably connected with a second connecting rod (not shown in the figure), and the ends of the first connecting rod 831 and the second connecting rod departing from the housing 83 are hinged with the bottom wall of the water container 1. When the air processing device 100 works, in the process that the floater 82 floats upwards, the cover 83 floats upwards along with the floater, and then the first connecting rod 831 and the second connecting rod of the cover 83 are driven to rotate around the hinge shaft, the horizontal distance between the magnetic field detection device 81 and the magnet is changed, the magnetic field intensity detected by the magnetic field detection device 81 is changed, and then a voltage signal is output.
The cover 83 may be snapped onto the float 82 or may be adhesively attached to the float 82. The casing 83 is made of a lightweight material, such as plastic, to be movable with the float 82 floating. Like the stationary box, the shape and size of the casing 83 can also be designed according to the shape and size of the float 82, respectively.
In the example shown in fig. 6, the cover 83 is rectangular, and a corner end of one side of the rectangular cover 83 has a notch, and the first connecting rod 831 can be accommodated in the notch; similarly, the corner end of the other side of the rectangular housing 83 may also be provided with a notch for accommodating the second connecting rod. As shown in fig. 5 and 6, the bottom wall of the water container 1 is provided with two bearing seats, the two bearing seats are arranged oppositely, the cover 83 is located between the two bearing seats, one end of the first connecting rod 831 is hinged with one of the bearing seats, and one end of the second connecting rod is hinged with the other bearing seat.
In other examples of the present disclosure, as shown in fig. 8, the cover 83 is provided with a mounting groove 832 toward the bottom of the float 82, and at least a portion of the magnet is caught in the mounting groove 832. With this arrangement, the magnet can be clamped to the housing 83 in addition to being fixed to the float 82, which is beneficial to improving the reliability of the connection between the magnet and the float 82, so as to ensure the effective operation of the magnet.
In this embodiment, with continued reference to fig. 5 and 6, the lower limit water level detecting device 8 further includes a limiting member 84, the limiting member 84 is fixed on the inner wall of the water container 1 and is located above one end of the casing 83 away from the hinge shaft; before the first link 831 and the second link rotate to the vertical state, the cover 83 abuts against the stopper 84. By providing the stopper 84, the stopper 84 limits the rotation of the cover 83 only in the space defined by the stopper 84 and the inner wall of the water container 1, so as to prevent the cover 83 and the float 82 from turning over due to the cover 83 continuing to rotate in the direction away from the magnetic field detection device 81 (clockwise direction in fig. 6) after the first link 831 and the second link are vertical.
The stopper 84 may have a block-like structure, a rod-like structure, or a plate-like structure. As shown in fig. 6, the limiting member 84 includes a limiting plate extending to the inside of the water container 1 along the horizontal direction, and connecting arms are vertically arranged on both sides of the limiting plate and connected to the inner wall of the water container 1 to enhance the stability of the limiting member 84.
On the basis of the above embodiment, the upper limit water level detection device comprises a light emitter 9 and a light receiver which are oppositely arranged on the inner wall of the water container 1, and the distances between the light emitter 9 and the light receiver and the bottom wall of the water container 1 are equal to the upper limit water level. Wherein, the light transmitter 9 and the light receiver are both electrically connected with the processor. Therefore, compared with the detection of the upper limit water level of the water container 1 by the liquid level detection device, the water curtain is not easy to form due to the fact that the water container 1 occupies too much space by the upper limit water level detection device. Moreover, the liquid level detection effect is achieved by utilizing the optical principle, and the detection principle is simple.
An exemplary operating principle of the upper limit water level detection device in this embodiment is as follows: when the water level of the water container 1 is not higher than the upper limit water level, the light emitter 9 emits light, the light receiver opposite to the light emitter 9 can receive the light, and the processor does not control the alarm to emit an alarm signal at the moment; when the water level of the water container 1 is higher than the upper limit water level, the light emitter 9 emits light, the light is projected into water, the light receiver cannot receive the light, and the processor controls the alarm to emit a water full alarm signal to prompt a user to stop adding water.
The light emitter 9 may be a light emitting diode, and correspondingly, the light receiver may be a photosensitive element; the light emitter 9 may also be an infrared emitter tube and correspondingly the light receiver may be an infrared receiver tube.
Further, as shown in fig. 7, an overflow 11 is provided on an outer wall of the water container 1, and the light emitter 9 is fixed in the overflow 11. Therefore, when the water in the water container 1 is higher than the upper limit water level, the processor responds to the detection of the water level value by the upper limit water level detection device, controls the alarm to send a full water alarm signal, and simultaneously, excess water can flow out of the overflow opening 11 so as to prevent the water in the water container 1 from exceeding the load.
The outer wall of the water container 1 is also provided with a water receiving tray, the water receiving tray is positioned below the overflow opening 11, the bottom of the water receiving tray is connected with a water guide pipe, and the water guide pipe guides water out of the air treatment device 100. With the above arrangement, it is possible to prevent water overflowing from the water container 1 from leaking into the air treatment apparatus 100, thereby preventing the performance of the electric parts on the air treatment apparatus 100 from being affected. It should be noted that when the air treatment device 100 is applied to a large air treatment apparatus (e.g., an air conditioner), the water conduit may be communicated with a drain pipe of the air conditioner so as to drain water.
The embodiment of the invention also provides an air conditioner, in particular to a cabinet air conditioner indoor unit, which comprises a shell and the air processing device 100 in any one of the embodiments, wherein the air processing device 100 is arranged in the shell. The shell is also internally provided with a heat exchange air channel which is isolated from the air treatment device 100, and the heat exchange air channel is independent from a flow channel which is arranged on the air treatment device 100 and used for purifying, humidifying or cooling air, so that the heat exchange function of an air conditioner indoor unit can be prevented from being influenced.
With the arrangement, when the water level of the water container 1 of the air treatment device 100 arranged in the air conditioner is lower than the lower limit water level, the alarm sends out a water shortage alarm signal to prompt a user to add water; when the water level of the water container 1 of the air treatment device 100 disposed in the air conditioner is higher than the upper limit water level, the alarm gives a full water alarm signal to prompt the user to stop adding water.
In summary, the embodiment of the present invention provides an air treatment device 100 and an air conditioner, the air treatment device 100 includes a water container 1, an upper limit water level detection device, a lower limit water level detection device 8, a processor, and an alarm, wherein the water container 1 is used for containing water; the upper limit water level detection device and the lower limit water level detection device 8 are arranged in the water container 1 at intervals up and down and are respectively used for detecting the upper limit water level and the lower limit water level of the water container 1; the processor is electrically connected with the lower limit water level detection device 8, the upper limit water level detection device and the alarm. When the water level of the water container 1 detected by the lower limit water level detection device 8 is lower than the lower limit water level, the processor controls the alarm to send out a water shortage alarm signal; when the upper limit water level detection device detects that the water level of the water container 1 is higher than the upper limit water level, the processor controls the alarm to send a full water alarm signal. Through the arrangement, the water shortage alarm signal sent by the alarm can prompt a user to add water so as to prevent the air treatment device 100 from working normally due to the fact that the water container 1 is short of water; the full water alarm signal sent by the alarm can prompt the user that the water level of the water container 1 exceeds the upper limit water level, so that the water in the water container 1 exceeds the load due to excessive water addition can be avoided.
