DETAILED DESCRIPTION

[0046] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings, are constructed and operated in a specific direction, and are only for the convenience of describing the present technical solution, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as a limitation to the present invention.

[0047] The utility model provides a control system for an atomizing spray device in an air-cooled air conditioner. The air-cooled air conditioner comprises a compressor 10 and a host 20 which is at least used for collecting a pressure feedback signal on the compressor 10. The host 20 is connected to the compressor 10, wherein the pressure feedback signal at least includes a pressure exhaust pressure value of the compressor 10.

[0048] like Figure 1 As shown, the control system for the atomizing spray device 70 in the air-cooled air conditioner may include a regulating valve 60, a temperature sensor 30, a humidity sensor 40 and a control module 50; wherein the regulating valve 60 is installed on the water inlet pipe of the atomizing spray device 70, and the water output of the atomizing spray device 70 is adjusted or the atomizing spray device 70 is shut down by the regulating valve 60; the temperature sensor 30 is installed on the air-cooled air conditioner; the humidity sensor 40 is installed on the air-cooled air conditioner; the control module 50 is respectively connected to the host 20, the temperature sensor 30, the humidity sensor 40 and the regulating valve 60, and the control module 50 is used to collect the temperature feedback signal output by the temperature sensor 30, the humidity feedback signal output by the humidity sensor 40 and the pressure feedback signal collected by the host 20, and output the regulating signal to the regulating valve 60 according to the temperature feedback signal, the humidity feedback signal and the pressure feedback signal, so as to control the opening of the regulating valve 60, and then adjust the water output of the atomizing spray device 70.

[0049] Among them, when setting, the temperature sensor 30 can be installed at the air inlet of the air-cooled air conditioner; when setting, the humidity sensor 40 can be installed at the air outlet of the air-cooled air conditioner; when the control module 50 is connected to the host 20, the communication method of RS-485 can be used for connection but is not limited to it.

[0050] like Fig.13As shown, it is a valve adjustment flow chart of the control system of the atomizing spray device 70 in the air-cooled air conditioner. The control module 50 collects the temperature feedback signal, the humidity feedback signal and the pressure feedback signal. When the temperature feedback signal does not exceed the set temperature, it is further determined whether the pressure feedback signal is too high. When the pressure feedback signal is not too high, the regulating valve 60 is closed; when the temperature feedback signal exceeds the set value or the pressure feedback signal is too high, it is further determined whether the humidity feedback signal exceeds the set value. When the humidity feedback signal exceeds the set value, the regulating valve 60 is opened, and the opening of the regulating valve 60 is controlled according to the pressure feedback signal (the opening of the regulating valve 60 is proportional to the pressure feedback signal). When the humidity feedback signal exceeds the set value, the regulating valve 60 is closed (the opening of the regulating valve 60 is inversely proportional to the humidity), and the humidity feedback signal is monitored in real time.

[0051] It can be seen that since the regulating valve 60 is arranged on the water inlet pipe of the atomizing spray device 70, the control module 50 can output the regulating signal to the regulating valve 60 by collecting the temperature feedback signal, the humidity feedback signal and the pressure feedback signal collected by the host 20 to adjust the opening of the regulating valve 60, and then adjust the water output of the atomizing spray device 70, and when the opening of the regulating valve 60 is 0, the atomizing spray device 70 stops spraying water. It can be seen that the control system of the atomizing spray device 70 in the air-cooled air conditioner can control the regulating valve 60 according to the temperature feedback signal, the humidity feedback signal and the pressure feedback signal, so that the atomizing spray device 70 can spray water on demand, saving water and electricity, and at the same time, slowing down the rust rate of the air-cooled air conditioner.

[0052] In some embodiments, Figure 2 - Figure 8 As shown, Figure 2 This is a partial pin diagram of the first chip. Figure 3 FIG. 5 is another partial pin diagram of the first chip. The control module 50 may include the first chip, a first interface J1 , a second interface J2 , a first voltage dividing unit 502 , a first operational amplifier unit 503 and a first switch unit 501 .

[0053] The first voltage dividing unit 502 has a first voltage signal input terminal and a first voltage signal output terminal. The first voltage signal input terminal is connected to the first pin of the first interface J1, and the first voltage signal output terminal is connected to the seventh pin of the first chip.

[0054] The first operational amplifier unit 503 has a second voltage signal input terminal and a second voltage signal output terminal. The second voltage signal input terminal is connected to the sixth pin of the first chip.

[0055] like Figure 6As shown, the first switch unit 501 may include a first resistor R1, a first transistor Q1, a first diode D1, and a first relay switch K1, wherein one end of the first resistor R1 is connected to the 81st pin of the first chip, the other end of the first resistor R1 is connected to the base of the first transistor Q1, the emitter of the first transistor Q1 is grounded, the collector of the first transistor Q1 is connected to the anode of the first diode D1, the cathode of the first diode D1 is connected to the power supply, the first pin of the first relay switch K1 is connected to the anode of the first diode D1, the second pin of the first relay switch K1 is connected to the cathode of the first diode D1, the third pin of the first relay switch K1 is connected to the first pin of the second interface J2, the fourth pin of the first relay switch K1 is connected to the second voltage signal output end, and the fifth pin of the first relay switch K1 is connected to the first pin of the first interface J1.

[0056] In this embodiment, when the signal type output by the temperature feedback signal or the humidity feedback signal is a voltage signal, the temperature feedback signal or the humidity feedback signal can be connected through the first pin of the first interface J1. After the connection, the temperature feedback signal or the humidity feedback signal is divided by the first voltage divider unit 502 and transmitted to the first chip. The first chip outputs a voltage signal to the first operational amplifier unit 503 according to the collected temperature feedback signal, the humidity feedback signal and the pressure signal collected by the host 20. The first operational amplifier unit 503 amplifies the voltage signal and outputs it to the first switch unit 501. At the same time, the first chip also outputs a voltage signal to the first transistor Q1. At this time, the first transistor Q1 is turned on, the first relay switch K1 is switched, and the adjustment signal is output to the first pin of the second interface J2 through the second pin of the first relay switch K1, thereby adjusting the opening of the regulating valve 60 to adjust the water output of the atomizing spray device 70. When the opening of the regulating valve 60 is 0, the atomizing spray device 70 is turned off and no longer sprays water.

[0057] Here, it should be noted that the output regulating signal is a voltage signal of 0-10V. Therefore, when selecting the regulating valve 60, it is also necessary to consider the type of the output regulating signal, that is, whether the opening can be adjusted by the voltage signal.

[0058] In this embodiment, the first chip may be, but is not limited to, a chip of model LPC1766FBD100.

[0059] Furthermore, if Figure 6 As shown, the first switch unit 501 also includes a second resistor R2 and a first light-emitting diode D3; wherein one end of the second resistor R2 is connected to the other end of the first resistor R1, the other end of the second resistor R2 is connected to the positive electrode of the first light-emitting diode D3, and the negative electrode of the first light-emitting diode D3 is grounded.

[0060] In this embodiment, when the first chip outputs a voltage signal to the first transistor Q1, the other end of the first resistor R1 is divided into two types, wherein one path is output to the first transistor Q1 to turn on the first transistor Q1, and the other path is output to the second resistor R2 to light up the first light-emitting diode D3. The first light-emitting diode D3 can be used to determine whether a voltage signal is output to the first transistor Q1.

[0061] In a specific embodiment, if Figure 7 As shown, the first voltage dividing unit 502 may include a third resistor R3 and a fourth resistor R4; wherein, one end of the fourth resistor R4 is connected to the 1st pin of the first interface J1, the other end of the fourth resistor R4 is connected to one end of the third resistor R3, the other end of the third resistor R3 is grounded, and one end of the third resistor R3 connected to the fourth resistor R4 is connected to the 7th pin of the first chip, wherein one end of the fourth resistor R4 is the first voltage signal input end, and one end of the third resistor R3 connected to the fourth resistor R4 is the first voltage signal output end.

[0062] In this embodiment, the third resistor R3 and the fourth resistor R4 can protect the first chip and prevent the first chip from being damaged by an overly high voltage signal.

[0063] In addition, the first operational amplifier unit 503 can be any circuit structure that can achieve the above functional requirements, for example, Figure 8 As shown, the first operational amplifier unit 503 may include a first operational amplifier, a ninth resistor R9, a tenth resistor R10 and an eleventh resistor R11, wherein one end of the ninth resistor R9 is grounded, the other end of the ninth resistor R9 is connected to the second pin of the first operational amplifier, one end of the tenth resistor R10 is connected to the sixth pin of the first chip, the other end of the tenth resistor R10 is connected to the third pin of the first operational amplifier, one end of the eleventh resistor R11 is connected to the other end of the ninth resistor R9, the other end of the eleventh resistor R11 is connected to the first pin of the first operational amplifier, the fourth pin of the first operational amplifier is grounded, and the fifth pin of the first operational amplifier is connected to the power supply, wherein the first operational amplifier may be selected but is not limited to an operational amplifier of model LM358U54-A, the first pin of the first operational amplifier is the second voltage signal output terminal, and one end of the tenth resistor R10 is the second voltage signal input terminal.

[0064] In some embodiments, Fig. 9 , Fig.10 and Fig.12As shown, the control module 50 also includes a first filtering unit 505, a second switch unit 504 and a voltage-current conversion unit 507; wherein the voltage-current conversion unit 507 is used to convert a voltage signal into a current signal output, and the voltage-current conversion unit 507 has a third voltage signal input terminal and a first current signal output terminal, the third voltage signal input terminal is connected to the second voltage signal output terminal, and the first current signal output terminal is connected to the second pin of the second interface J2; the first filtering unit 505 has a first current signal input terminal and a second current signal output terminal, the first current signal input terminal is connected to the third pin of the first interface J1, and the second current signal output terminal is connected to the 21st pin of the first chip; the second switch unit 504 includes a fifth resistor R5, a second transistor Q2, a second diode D2, and a The second relay switch K2, one end of the fifth resistor R5 is connected to the 32nd pin of the first chip, the other end of the fifth resistor R5 is connected to the base of the second transistor Q2, the emitter of the second transistor Q2 is grounded, the collector of the second transistor Q2 is connected to the positive electrode of the second diode D2, the negative electrode of the second diode D2 is connected to the power supply, the first pin of the second relay switch K2 is connected to the positive electrode of the second diode D2, the second pin of the second relay switch K2 is connected to the negative electrode of the second diode D2, the fourth pin of the second relay switch K2 is connected to the first current signal output end, the fourth pin of the second relay switch K2 is also connected to the second pin of the second interface J2, the fifth pin of the second relay switch K2 is connected to the third pin of the first interface J1, and the third pin of the second relay switch K2 is connected to the third pin of the second interface J2.

[0065] In this embodiment, when the temperature feedback signal and the humidity feedback signal are current signals, the temperature feedback signal or the humidity feedback signal can be connected through the third pin of the first interface J1. After connection, the temperature feedback signal or the humidity feedback signal is output to the first chip through the first filtering unit 505. The first chip outputs a voltage signal to the first operational amplifier unit 503 based on the collected temperature feedback signal, humidity feedback signal and the pressure signal collected by the host 20.

[0066] It can be seen that when the signal type output by the temperature sensor 30 and the humidity sensor 40 is a current signal, it can also be applied to the control system of the atomizing spray device 70 used in the air-cooled air conditioner.

[0067] In addition, since the second switch unit 504 and the voltage-current conversion unit 507 are provided, when outputting the regulating signal, the regulating signal can be outputted through the current signal or the voltage signal. When the voltage signal is used as the regulating signal, the voltage signal outputted by the first chip is outputted to the first operational amplifier unit 503, and the first operational amplifier unit 503 amplifies the voltage signal and outputs it to the first switch unit 501. At the same time, the first chip also outputs the voltage signal to the first transistor Q1. At this time, the first transistor Q1 is turned on, and the first relay switch K1 is switched, and the regulating signal is outputted to the second interface J2 through the third pin of the first relay switch K1. The first pin of the first chip is used to adjust the opening of the regulating valve 60; when the current signal is used as the regulating signal, the voltage signal output by the first chip is output to the first operational amplifier unit 503, and the first operational amplifier unit 503 amplifies the voltage signal and outputs it to the voltage-current conversion unit 507, which is converted into a current signal by the voltage-current conversion unit 507 and then output to the second switch unit 504. At the same time, the first chip also outputs a voltage signal to the second transistor Q2. At this time, the second transistor Q2 is turned on, and the second relay switch K2 is switched, and the regulating signal is output to the third pin of the second interface J2 through the third pin of the second relay switch K2, thereby adjusting the opening of the regulating valve 60.

[0068] Furthermore, when the temperature feedback signal and the humidity feedback signal connected to the first chip are current signals, they are first passed through the first filtering unit 505 and then connected to the first chip, and the interference signal and clutter in the current signal are filtered out by the first filtering unit 505 .

[0069] It can be seen that when selecting the regulating valve 60, a valve capable of receiving a 0-10V voltage signal or a valve capable of receiving a 4-20mA current signal can be selected. Those skilled in the art can determine the specific type of valve according to actual needs. When the selected valve is a valve capable of receiving a 0-10V voltage signal, the valve is connected to the first pin of the second interface J2; when the selected valve is a valve capable of receiving a 4-20mA current signal, the valve is connected to the second pin of the second interface J2.

[0070] In this example, the voltage-current conversion unit 507 may be a circuit structure diagram with model XTR110 as the main component, as shown in FIG. Fig.12 As shown, the voltage-current conversion unit 507 is constructed with the model XTR110 as the main component, which can convert the 0-10V voltage signal into a 4-20mA current signal.

[0071] In a specific embodiment, if Fig.10 As shown, the first filtering unit 505 may include a sixth resistor R6 and a first capacitor C1; one end of the sixth resistor R6 is connected to the 3rd pin of the first interface J1, one end of the first capacitor C1 is connected to one end of the sixth resistor R6, the other end of the first capacitor C1 and the other end of the sixth resistor R6 are connected to ground, and the connection end between one end of the first capacitor C1 and one end of the sixth resistor R6 is also connected to the 21st pin of the first chip.

[0072] Furthermore, if Fig. 9 As shown, the second switch unit 504 also includes a seventh resistor R7 and a second light-emitting diode D4; one end of the seventh resistor R7 is connected to the other end of the fifth resistor R5, the other end of the seventh resistor R7 is connected to the positive electrode of the second light-emitting diode D4, and the negative electrode of the second light-emitting diode D4 is grounded.

[0073] In this embodiment, when the first chip outputs a voltage signal to the second transistor Q2, the other end of the fifth resistor R5 is divided into two types, wherein one path is output to the second transistor Q2 to turn on the second transistor Q2, and the other path is output to the fifth resistor R5 to light up the second light-emitting diode D4. The second light-emitting diode D4 can be used to determine whether a voltage signal is output to the second transistor Q2.

[0074] In some embodiments, Fig.11 As shown, the control module 50 also includes a second filtering unit 506, which has a second current signal input terminal and a third current signal output terminal. The second current signal input terminal is connected to the second pin of the first interface J1, and the third current signal output terminal is connected to the 20th pin of the first chip.

[0075] Specifically, Fig.11 As shown, the second filtering unit 506 may include an eighth resistor R8 and a second capacitor C2, one end of the eighth resistor R8 is connected to the second pin of the first interface J1, one end of the second capacitor C2 is connected to one end of the eighth resistor R8, the other end of the eighth resistor R8 and the other end of the second capacitor C2 are connected to ground, and the connection end between one end of the eighth resistor R8 and one end of the second capacitor C2 is also connected to the 20th pin of the first chip.

[0076] In this embodiment, the second pin of the first interface J1 can be used as another path to connect the current signal to the first chip, so as to expand the current signal access path.

[0077] In some embodiments, the regulating valve 60 may be a proportional integral valve. Of course, it may also be other types of valves that can adjust the water output of the atomizing spray device 70 and can be electronically controlled.

[0078] In this embodiment, the proportional-integral valve may be a valve capable of receiving a 0-10V voltage signal or a valve capable of receiving a 4-20mA current signal. Those skilled in the art may determine the specific type of valve according to actual needs. When the selected proportional-integral valve is a valve capable of receiving a 0-10V voltage signal, the proportional-integral valve is connected to the first pin of the second interface J2; when the selected proportional-integral valve is a valve capable of receiving a 4-20mA current signal, the proportional-integral valve is connected to the second pin of the second interface J2.

[0079] In this embodiment, when the signal type output by the temperature sensor 30 and the humidity sensor 40 is a voltage signal, the voltage signal can be a 0-10V voltage signal; when the signal type output by the temperature sensor 30 and the humidity sensor 40 is a current signal, the current signal can be a 4-20mA current signal; in addition, the power supply is a +12V DC power supply voltage.

[0080] In summary, the utility model provides a control system for a misting spray device 70 in an air-cooled air conditioner. Since the regulating valve 60 is arranged on the water inlet pipe of the misting spray device 70, the control module 50 can output a regulating signal to the regulating valve 60 by collecting the temperature feedback signal, the humidity feedback signal and the pressure feedback signal collected by the host 20 to control the opening of the regulating valve 60, thereby adjusting the water output of the misting spray device 70, and when the opening of the regulating valve 60 is 0, the misting spray device 70 stops spraying water. It can be seen that the control system for the misting spray device 70 in the air-cooled air conditioner can control the regulating valve 60 according to the temperature feedback signal, the humidity feedback signal and the pressure feedback signal, so that the misting spray device 70 can spray water on demand, saving water and electricity, and at the same time, slowing down the rust rate of the air-cooled air conditioner.

[0081] In addition, the control system can also record water flow in real time and display water consumption. At the same time, it can also regularly control the rotation of the air-cooled air conditioner to dry the water, further slowing down the rate of rust.

[0082] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
