Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to an air treatment device having drainage capabilities. [Background technology]

[0002] Conventionally, in air treatment devices such as ventilation equipment having an air conditioner and a humidifier, parts gradually become dirty as the device operates, and the drainage capacity of the drainage device decreases with age. Therefore, it is generally considered advisable to perform maintenance such as cleaning and replacing parts every certain period of operation. By performing maintenance periodically, the air treatment device can be preserved. To encourage the user to perform maintenance, there are devices that notify the user of the need for maintenance over time.

[0003] In air treatment equipment with a drainage function, a decrease in the drainage capacity of parts such as the drain pump that drains the drain water from inside the equipment to the outside of the equipment directly leads to a malfunction in the form of water leaking outside the equipment. However, it is not realistic to install a flow meter to inspect the drainage capacity of the equipment, and notifications of abnormalities issued by water level sensors, etc. are often used to determine the timing of part replacement.

[0004] Maintenance and inspection are left to the discretion of the user, and maintenance is rarely carried out due to the desire to perform the minimum necessary maintenance in order to keep costs down as much as possible. In reality, maintenance is not always carried out until a malfunction occurs, so there is a demand for air treatment equipment that can determine whether maintenance is necessary and the appropriate timing for maintenance.

[0005] For example, as disclosed in Patent Document 1, a system has been proposed that has an imaging unit that images a drain pan inside a casing, and estimates the timing for maintenance regarding dirt on the drain pan based on image data obtained by imaging, operating data, environmental data, etc. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 6944962 Summary of the Invention [Problem to be solved by the invention]

[0007] The technology disclosed in Patent Document 1 requires an imaging unit, and estimates the timing of maintenance using information on the rotation speed and operation time of the drain pump, so that more accurate information on the timing of maintenance can be obtained. However, in the technology disclosed in Patent Document 1, the air treatment device requires components such as an imaging unit that are not necessary for the function.

[0008] In addition, the technology disclosed in Patent Document 1 uses environmental data and machine learning, etc., and accurate data input and accumulation of past data affect the accuracy of estimating the timing of maintenance. Therefore, although the technology disclosed in Patent Document 1 has the advantage of being able to monitor the drain pan using an imaging unit, there are issues with the accuracy of the estimated information.

[0009] The present disclosure has been made in consideration of the above, and aims to provide an air treatment device that can contribute to informing users when maintenance is required without having functionally unnecessary components. [Means for solving the problem]

[0010] In order to solve the above problems and achieve the object, the air treatment device according to the present disclosure has a water supply means capable of switching between performing an operation of supplying water into the interior of the device or performing an operation of generating water, a drain pan for holding the supplied water or the generated water, a water level detection means for detecting the water level inside the drain pan, a drainage means capable of switching between performing an operation of discharging water outside the device, and a control unit including a memory and a timer function, which measures a water supply inspection time and a drainage inspection time based on the performing or not performing of the operations of the water supply means and the drainage means and the water level detected by the water level detection means. The control unit estimates the water supply capacity based on the measured water supply inspection time and a preset water retention amount, and estimates the drainage capacity based on the estimated water supply capacity and the measured drainage inspection time. Effect of the Invention

[0011] The air treatment device according to the present disclosure has an effect of contributing to notifying a user of the timing of maintenance without having components that are unnecessary from a functional standpoint. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An air treatment device according to an embodiment will be described in detail below with reference to the drawings.

[0014] Embodiment 1 Fig. 1 is a functional block diagram showing a control unit 1 of an air treatment device according to embodiment 1. Fig. 1 shows an outline of the internal configuration of the control unit 1 and an outline of information input / output for the control unit 1. The control unit 1 has an input interface 2, an output interface 3, and a microcomputer 7. Fig. 1 also shows means other than the components of the control unit 1.

[0015] The input interface 2 receives information on the water level detected by the water level detection means 4 and remote controller operation information 12 including maintenance information input from a control remote controller. The water level detection means 4 is included in the air treatment device. The remote controller is not shown. Information from the control unit 1 is output to the outside as output device information 13 through the output interface 3. The water supply means 5 and the drainage means 6 operate according to commands from the control unit 1. The water supply means 5 and the drainage means 6 are included in the air treatment device.

[0016] The water supply means 5 is a device that receives an output signal from the microcomputer 7 and turns on or off a solenoid valve to supply water from outside the machine or to stop water supply to the air treatment device, thereby making it possible to supply water to the inside of the machine. More specifically, the water supply means 5 is a means that can switch between whether or not to perform an operation to supply water to the inside of the machine or an operation to generate water.

[0017] The drainage means 6 is a device that receives an output signal from the microcomputer 7 and performs an operation of draining water or stopping water from the air treatment device to the outside of the device by turning on or off the drain pump, etc., thereby making it possible to discharge water outside the device. More specifically, the drainage means 6 is a means that can switch between whether or not to perform the operation of draining water outside the device.

[0018] The output device information 13 is maintenance information, and is output to a terminal as a remote controller display 14 upon receiving an output signal from the microcomputer 7. The terminal is not shown. The output device information 13 is information on whether maintenance is required, etc., and is output to the outside as a contact signal 15. The external device can use the contact signal 15. The external device is not shown. The output device information 13 is detailed numerical data, and is output to the outside as a communication signal 16. The external device can collect and process the detailed numerical data. The output device information 13 may be output to the outside by means other than those described above, as long as it is information that can be processed by the control unit 1.

[0019] The microcomputer 7 performs the drainage capacity estimation according to the first embodiment based on the water level information and setting information received from the input interface 2, outputs a signal to the output interface 3, and processes the information.

[0020] The microcomputer 7 has a processor such as a CPU (Central Processing Unit), memories such as a RAM (Random Access Memory) and a ROM (Read Only Memory), and a timer. The microcomputer 7 has, as functional parts, a timer section 8 that counts time based on water level information and water supply and drainage status, a maintenance information storage section 9 that stores setting information for selecting output device information based on an estimated drainage capacity and setting information related to drainage capacity estimation, a water supply capacity calculation section 10 that calculates the water supply capacity, and a drainage capacity calculation section 11 that calculates the drainage capacity. The maintenance information storage section 9 is realized by the above-mentioned memory.

[0021] FIG. 2 is a schematic diagram showing the configuration of an air treatment device 51 according to the first embodiment. The air treatment device 51 has a casing 17 and a control unit 1 that estimates the drainage capacity and inputs and outputs data. The control unit 1 has a memory and a timer function, and measures the water supply inspection time and the drainage inspection time based on whether the water supply means 5 and the drainage means 6 are operating and the water level detected by the water level detection means 4. The control unit 1 estimates the water supply capacity based on the measured water supply inspection time and a preset water retention volume, and estimates the drainage capacity based on the estimated water supply capacity and the measured drainage inspection time. The control unit 1 may estimate the drainage capacity based on the measured water supply inspection time and drainage inspection time and the preset water retention volume.

[0022] The control unit 1 uses either or both of the estimated water supply capacity and the estimated drainage capacity to determine whether maintenance of the water supply means 5 or the drainage means 6 is necessary and whether the operating state is normal or not. The control unit 1 may use the estimated drainage capacity to determine either or both of whether maintenance of the water supply means 5 or the drainage means 6 is necessary and whether the operating state is normal or not. When the control unit 1 determines that maintenance is necessary or that the operating state is abnormal, it performs protective operation to stop, intermittently, or reduce the output of the water supply means 5 until the target part is replaced or until normal operation is restored.

[0023] The air treatment device 51 further includes water supply means 5 which supplies water to the interior of the device according to an output from the control unit 1, a humidifier 20 which performs humidification processing with water supplied from the water supply means 5, a water supply path 21 for guiding water supply 19 from a water supply source to the humidifier 20 via the water supply means 5, and a drain pan 18 for holding drain water generated inside the device, such as water discharged from the humidifier 20. The drain pan 18 holds the supplied water or water generated.

[0024] Air treatment device 51 further includes water level detection means 4 for detecting the water level inside drain pan 18, drainage means 6 for performing a drainage operation to discharge the water inside drain pan 18 to the outside of the device by output from control unit 1, and drainage path 23 for draining 22 drain water generated inside the device to the outside of the device. Fig. 2 shows only components necessary for performing drainage capacity estimation, and does not show components that are not related to drainage capacity estimation even if they are components of a general air treatment device, such as a blower and an air intake port.

[0025] The humidifier 20 has a plurality of sheet-like humidifying bodies formed of a porous material. The plurality of humidifying bodies are stacked. Each of the plurality of humidifying bodies is arranged with a space between adjacent humidifying bodies. In the humidifier 20, water supply 19 is dripped onto the plurality of humidifying bodies from above, so that the water supply 19 permeates each humidifying body, and air is blown over the surface of each humidifying body, thereby humidifying the air with the moisture evaporated from each humidifying body. The remaining water, excluding the amount of water that has evaporated from each humidifying body and the moisture retained in each humidifying body, drips into the drain pan 18 as drain water.

[0026] The humidifier 20 is not limited to a drip-type humidifier in which the supply water 19 is dripped from above. For example, the humidifier 20 may be a humidifier that has a plurality of bag-shaped humidifying bodies formed of a moisture-permeable membrane, stores the supply water 19 from the water supply means 5 in the bag of each humidifying body, further has a drain pipe leading from the lower part of each humidifying body bag to the drain pan 18, and a drain valve provided in the drain pipe, and flows the drain water into the drain pan 18 by opening the water supply valve and the drain valve provided in the water supply means 5.

[0027] FIG. 3 is a flow chart showing the procedure for estimating the drainage capacity performed by the control unit 1 of the air treatment device 51 according to the first embodiment.

[0028] Step S1 is a water supply capacity inspection step, in which the control unit 1 estimates the water supply capacity based on the amount of water supplied to the inside of the machine, which changes depending on the construction state and the state of the equipment, and the measurement time of the water amount.

[0029] Step S2 is a drainage capacity inspection step, in which the control unit 1 uses the water supply capacity and drainage time estimated in step S1 to estimate the drainage capacity for water discharged outside the machine, which varies depending on the construction status and equipment status, etc.

[0030] In step S3, the control unit 1 outputs the device information estimated in steps S1 and S2 to the outside. The device information includes information indicating the water supply capacity estimated in step S1 and information indicating the drainage capacity estimated in step S2.

[0031] After completing the output of the device information in step S3, the control unit 1 stores information indicating the estimated drainage capacity in the memory of the microcomputer 7, and resets the timer information when the estimation of the drainage capacity is completed.

[0032] 4 is a flowchart showing the procedure for calculating water supply capacity in estimating the drainage capacity according to embodiment 1. FIG 4 shows the detailed contents of the water supply capacity inspection step S1 in FIG 3.

[0033] In step S4, the control unit 1 operates the water supply means 5 to supply water to the on-board humidifier 20. In Fig. 4, the operation of step S4 is indicated by the phrase "water supply means = ON." Note that the state before the water supply operation is performed is a state in which no water has accumulated in the drain pan 18, or a state in which drainage has been completed and the amount of water remaining in the drain pan 18 is a known amount.

[0034] In step S5, the timer unit 8 of the control unit 1 sets the water supply time T in1 The timer unit 8 may directly count the time, or may count the number of times at an arbitrary cycle.

[0035] In step S6, the control unit 1 determines whether the water level detection means 4 is submerged or not. In Fig. 4, the operation of step S6 is indicated by the phrase "Water level detection means = submerged?" In the first embodiment, it is assumed that the water level detection means 4 is an electrode-type or float-type water level detection means. Therefore, the input signal from the water level detection means 4 to the control unit 1 is a signal indicating submersion, which is detected when the water level, which is the height of the water accumulated in the drain pan 18, reaches a given water level, or a signal indicating air, which is detected when the water level has not reached a given water level.

[0036] When the control unit 1 determines that the water level detection means 4 is not submerged (No in step S6), the operation of the control unit 1 returns to step S5, and the timer unit 8 of the control unit 1 starts the water supply time T in1 Continue counting.

[0037] When the control unit 1 determines that the water level detection means 4 is submerged (Yes in step S6), the operation of the control unit 1 proceeds to step S7.

[0038] In step S7, the control unit 1 stops the water supply means 5 to terminate the water supply operation to the in-machine humidifier 20. In Fig. 4, the operation of step S7 is indicated by the words "Water supply means = OFF".

[0039] In step S8, the water supply capacity calculation unit 10 of the control unit 1 calculates the unknown water supply capacity Q in After the operation of step S7 is completed, the water supply time T in1 Since the count and water supply have stopped, the unknown water supply capacity Q in Water supply time T in1 Water supply is being performed, and the amount of water supplied to the drain pan 18 is M, which is the water supply capacity Q in and water supply time T in1 In FIG. 4, the operation of step S8 is "Water supply capacity calculation Q in =M / T in1 " This is indicated by the words:

[0040] The water level detected by the water level detection means 4 can be freely selected at the design stage, so the amount of water remaining in the drain pan 18 when the water level inside the drain pan 18 reaches the water level detected by the water level detection means 4 can be known in advance. Therefore, the water supply amount M, which is the amount of water supplied from step S4 to step S7, is known, so the water supply capacity Q in is the known water supply amount M and water supply time T in1 Using these, it is derived using the following equation (1).

[0042] FIG. 5 is a flowchart showing the procedure of drainage capacity calculation in drainage capacity estimation according to the first embodiment, and shows details of drainage capacity inspection step S2 in FIG.

[0043] In step S9, the control unit 1 operates the drainage means 6 to perform the drainage operation to the outside of the apparatus. In Fig. 5, the operation of step S9 is indicated by the phrase "drainage means = ON".

[0044] In step S10, the timer unit 8 of the control unit 1 starts the drainage time T out The timer unit 8 may directly count the time, or may count the number of times at an arbitrary cycle.

[0045] In step S11, the control unit 1 determines the drainage time T out is the drain check time T outcheck It is judged whether the drain check time T outcheck is a time that can be set arbitrarily, and the drain check time T outcheck The shorter the time, the lower the accuracy of the drainage capacity, but the shorter the inspection time.

[0046] The control unit 1 determines the drainage time T out is the drain check time T outcheckIf it is determined that the drain time is not longer than the drain time T (No in step S11), the operation of the control unit 1 returns to step S10, and the timer unit 8 of the control unit 1 starts the drain time T out Continue counting.

[0047] The control unit 1 determines the drainage time T out is the drain check time T outcheck If it is determined that this is the case (Yes in step S11), the operation of the control unit 1 proceeds to step S12.

[0048] In step S12, the control unit 1 stops the drainage means 6 to end the drainage operation to the outside of the machine. In FIG. 5, the operation of step S12 is indicated by the phrase "Drainage means=OFF". The state at this time is the unknown drainage capacity Q out Drain check time T outcheck The drainage amount M is the amount of water discharged to the outside of the drain pan 18 after drainage has been performed. out is the drainage capacity Q out and drain check time T outcheck This can be calculated by multiplying it with

[0049] In step S13, the control unit 1 operates the water supply means 5 to supply water to the on-board humidifier 20. In Fig. 5, the operation of step S13 is indicated by the phrase "water supply means = ON".

[0050] In step S14, the timer unit 8 of the control unit 1 sets the water supply time T in2 The timer unit 8 may directly count the time, or may count the number of times at an arbitrary cycle.

[0051] In step S15, the control unit 1 judges whether the water level detection means 4 is submerged or not. In FIG. 5, the operation of step S15 is indicated by the phrase "Water level detection means = submerged?" If the control unit 1 judges that the water level detection means 4 is not submerged (No in step S15), the operation of the control unit 1 returns to step S14, and the timer unit 8 of the control unit 1 starts counting the water supply time T in2 Continue counting.

[0052] When the control unit 1 determines that the water level detection means 4 is submerged (Yes in step S15), the operation of the control unit 1 proceeds to step S16.

[0053] In step S16, the control unit 1 stops the water supply means 5 to terminate the water supply operation to the in-machine humidifier 20. In FIG. 5, the operation of step S16 is indicated by the phrase "water supply means=OFF". The state at this time is the known water supply capacity Q in Water supply time T in2 The water supply is performed, and the amount of water supplied to the drain pan 18 is the water supply amount M in is water supply capacity Q in and water supply time T in2 It is a known quantity that can be calculated by multiplying with

[0054] In step S17, the drainage capacity calculation unit 11 of the control unit 1 calculates the unknown drainage capacity Q out Calculate the displacement M obtained in step S12. out and the water supply amount M obtained in step S16 in Since it is the same as the unknown drainage capacity Q out is derived by the following formula (2) using known values. In FIG. 5, the operation of step S17 is "drainage capacity calculation Q out =Q in ×T in2 / T outcheck " It is indicated by the wording. In addition, the drainage capacity Q out is water supply capacity Q in It can also be calculated from the measurement results alone without using

[0055]

number

[0056] By the above sequence, the air treatment device 51 according to the first embodiment can calculate the drainage capacity by actual measurement. The drainage capacity is related to the timing of maintenance such as the timing of part replacement. Since the air treatment device 51 can calculate the drainage capacity, it can contribute to informing the user of the timing of maintenance without having any functionally unnecessary components.

[0057] Embodiment 2 FIG. 6 is a schematic diagram showing the configuration of an air treatment device 52 according to the second embodiment. The air treatment device 52 has a casing 17, a control unit 1 that estimates the drainage capacity and inputs and outputs, a temperature control coil 24 that performs a temperature control operation according to the output from the control unit 1, an air supply blower 26 that performs an air blowing operation according to the output from the control unit 1, a drain pan 18 for holding condensed water 25 generated when the temperature control coil 24 cools the blown air supply 27, a water level detection means 4 for detecting the water level inside the drain pan 18, a drainage means 6 that performs a drainage operation to discharge the water inside the drain pan 18 to the outside of the device according to the output from the control unit 1, and a drainage path 23 for guiding the drain water generated inside the device to the outside of the device and draining it 22. FIG. 6 shows only the components necessary for performing the drainage capacity estimation, and does not show components that are not related to the drainage capacity estimation even if they are components of a general air treatment device, such as a blower and an air supply port.

[0058] FIG. 7 is a flow chart showing the procedure for estimating the drainage capacity performed by the control unit 1 of the air treatment device 52 according to the second embodiment.

[0059] In step S18, the control unit 1 operates the temperature control coil 24. In FIG. 7, the operation of step S18 is indicated by the phrase "temperature control coil = ON". Unlike the first embodiment, the second embodiment estimates the drainage capacity using condensed water by the temperature control coil 24, rather than water supplied to the humidifier 20. Therefore, in the air treatment device 52, the temperature control coil 24 must be performing cooling operation at the time of inspection. Therefore, the operation of step S18 means cooling operation. The cooling operation state is the thermo-on state.

[0060] Step S19 is a water supply capacity inspection step, and in step S19, the control unit 1 estimates the water supply capacity based on the amount of condensed water generated inside the machine, which changes depending on the construction state and the state of the equipment, etc., and the measurement time of the condensed water amount.

[0061] In step S20, the control unit 1 stops the temperature control coil 24. In Fig. 7, the operation of step S20 is indicated by the phrase "temperature control coil = OFF". In the second embodiment, the control unit 1 stops the temperature control coil 24 because it is assumed that the drainage capacity estimation is performed regardless of the operating state of the air treatment device 52. However, when the drainage capacity estimation is performed while the air treatment device 52 is in operation, it is not necessary to operate or stop the operation of the temperature control coil 24 individually in steps S18 and S20, and it is sufficient that the temperature control coil 24 is in the operating state corresponding to the inspection state.

[0062] Step S21 is a drainage capacity inspection step, in which the control unit 1 uses the water supply capacity and drainage time estimated in step S19 to estimate the drainage capacity for water drained outside the machine, which varies depending on the construction condition and equipment condition, etc.

[0063] In step S22, the control unit 1 outputs to the outside the device information estimated in steps S19 and S21. The device information includes information indicating the water supply capacity estimated in step S19 and information indicating the drainage capacity estimated in step S21. After completing the output of the device information in step S22, the control unit 1 stores the information indicating the estimated drainage capacity in the memory of the microcomputer 7, and resets the timer information when the estimation of the drainage capacity is completed.

[0064] FIG. 8 is a flowchart showing the procedure for calculating the water supply capacity in the drainage capacity estimation according to the second embodiment, and shows details of the water supply capacity inspection step S19 in FIG.

[0065] In step S23, the control unit 1 operates the intake air blower 26 to generate condensed water through cooling operation, and supplies water to the interior of the device. In Fig. 8, the operation of step S23 is indicated by the phrase "intake air blower = ON". Note that the state before the intake air blower 26 operates is a state in which no water has accumulated in the drain pan 18 of the air treatment device 52, or a state in which drainage has been completed and the amount of water remaining in the drain pan 18 is a known amount.

[0066] In step S24, the timer unit 8 of the control unit 1 counts the water supply time T in1 The timer unit 8 may directly count the time, or may count the number of times at an arbitrary cycle.

[0067] In step S25, the control unit 1 determines whether the water level detection means 4 is submerged or not. In Fig. 8, the operation of step S25 is indicated by the phrase "Water level detection means = submerged?" In the second embodiment, it is assumed that the water level detection means 4 is an electrode-type or float-type water level detection means, and therefore the input signal from the water level detection means 4 to the control unit 1 is a signal indicating submersion, which is detected when the water level, which is the height of the water accumulated in the drain pan 18, reaches a given water level, or a signal indicating air, which is detected when the water level has not reached a given water level.

[0068] When the control unit 1 determines that the water level detection means 4 is not submerged (No in step S25), the operation of the control unit 1 returns to step S24, and the timer unit 8 of the control unit 1 starts the water supply time T in1 Continue counting.

[0069] When the control unit 1 determines that the water level detection means 4 is submerged (Yes in step S25), the operation of the control unit 1 proceeds to step S26.

[0070] In step S26, the control unit 1 stops the intake air blower 26 to terminate the generation of condensed water due to the cooling operation, and terminates the operation of supplying water to the interior of the aircraft. In Fig. 8, the operation of step S26 is indicated by the phrase "intake air blower = OFF".

[0071] In step S27, the water supply capacity calculation unit 10 of the control unit 1 calculates the unknown water supply capacity Q in After the operation of step S26 is performed, the water supply time T in1 Since the count and condensation generation have stopped, the unknown water supply capacity Q in Water supply time T in1 Water supply is being performed. The amount of water supplied to the drain pan 18, M, is the water supply capacity Q in and water supply time T in1 In FIG. 8, the operation of step S27 is "water supply capacity calculation Q in =M / T in1 " This is indicated by the words:

[0072] Water supply capacity Q in is the known water supply amount M and water supply time T in1 Using these, it is derived using equation (1) in the same manner as in the first embodiment.

[0073] FIG. 9 is a flowchart showing the procedure of drainage capacity calculation in drainage capacity estimation according to the second embodiment, and shows details of drainage capacity inspection step S21 in FIG.

[0074] In step S28, the control unit 1 operates the drainage means 6 to perform the drainage operation to the outside of the apparatus. In Fig. 9, the operation of step S28 is indicated by the phrase "Drainage means = ON".

[0075] In step S29, the timer unit 8 of the control unit 1 counts up the drainage time T out The timer unit 8 may directly count the time, or may count the number of times at an arbitrary cycle.

[0076] In step S30, the control unit 1 determines the drainage time T out is the drain check time T outcheck It is judged whether the drain check time T outcheck is a time that can be set arbitrarily, and the drain check time T outcheckThe shorter the time, the lower the accuracy of the drainage capacity, but the shorter the inspection time.

[0100] In step S41, the control unit 1 operates the water supply means 5 to supply water to the interior of the apparatus. In Fig. 12, the operation of step S41 is indicated by the phrase "Water supply means = ON".

[0112] When the control unit 1 determines that the second water level detection means 36 is not in the air (No in step S47), the operation of the control unit 1 returns to step S46, and the control unit 1 continues to perform the drainage operation.

[0113] When the control unit 1 determines that the second water level detection means 36 is in the air (Yes in step S47), the operation of the control unit 1 proceeds to step S48.

[0114] In step S48, the timer unit 8 of the control unit 1 counts up the drainage time T out The timer unit 8 may directly count the time, or may count the number of times at an arbitrary cycle.

[0115] In step S49, the control unit 1 judges whether or not the first water level detection means 35 is in the air. In Fig. 13, the operation of step S49 is indicated by the phrase "First water level detection means = in the air?"

[0116] When the control unit 1 determines that the first water level detection means 35 is not in the air (No in step S49), the operation of the control unit 1 returns to step S48, and the timer unit 8 of the control unit 1 counts down the drain time T out Continue counting.

[0117] When the control unit 1 determines that the first water level detection means 35 is in the air (Yes in step S49), the operation of the control unit 1 proceeds to step S50.

[0118] In step S50, the control unit 1 stops the drainage means 6 to end the drainage operation to the outside of the apparatus. In Fig. 13, the operation of step S50 is indicated by the words "Drainage means = OFF".

[0119] By the above sequence, the air treatment device 53 according to the third embodiment can calculate the ratio of the drainage capacity to the water supply capacity by actually measuring the water supply time and the drainage time. The ratio of the drainage capacity to the water supply capacity is related to the timing of maintenance such as the timing of replacing parts. Since the air treatment device 53 can calculate the ratio of the drainage capacity to the water supply capacity, it can contribute to informing the user of the timing of maintenance without having any functionally unnecessary components.

[0120] Embodiment 4 14 is a schematic diagram showing the configuration of an air treatment device 54 according to embodiment 4. The air treatment device 54 has a casing 17, a control unit 1 that estimates and inputs / outputs the drainage capacity, a temperature control coil 24 that performs a temperature control operation according to the output from the control unit 1, an air supply blower 26 that performs an air blowing operation according to the output from the control unit 1, a drain pan 18 for holding condensed water 25 generated when the temperature control coil 24 cools the blown supply air 27, a first water level detection means 35 and a second water level detection means 36 for detecting the water level inside the drain pan 18, a drainage means 6 that performs a drainage operation to discharge the water inside the drain pan 18 to the outside of the machine according to the output from the control unit 1, and a drainage path 23 for guiding the drain water generated inside the machine to the outside of the machine and draining 22. The first water level detection means 35 is arranged so as to be able to detect a water level lower than that of the second water level detection means 36. FIG. 14 shows only the components necessary for performing drainage capacity estimation, and does not show components that are not related to drainage capacity estimation, even if they are components that are found in general air treatment devices, such as a blower and an air intake.

[0121] In embodiment 4, as in embodiment 3, there is no need to store the water retention capacity in advance in the microcomputer 7. By fixing the amount of water retained between the first water level detection means 35 and the second water level detection means 36, the control unit 1 calculates the ratio of drainage capacity to water supply capacity from the ratio of water supply and drainage times.

Unlike embodiment 3, in embodiment 4, the drainage capacity is estimated using condensed water by the temperature control coil 24, not water supply by humidification, so that the cooling operation needs to be performed by the temperature control coil 24 at the time of inspection. Therefore, the operation of step S51 means cooling operation. The cooling operation state is the thermo-on state.

[0124] Step S52 is a water supply time measurement step, in which the control unit 1 measures the time required to retain the amount of water between the first water level detection means 35 and the second water level detection means 36, of the amount of water supplied to the interior of the machine, which changes depending on the construction state, the state of the equipment, etc.

[0125] In step S53, the control unit 1 stops the temperature control coil 24. In FIG. 15, the operation of step S53 is indicated by the phrase "temperature control coil = OFF". In the third embodiment, since it is assumed that the drainage capacity estimation is performed regardless of the operating state of the air treatment device 54, the control unit 1 stops the temperature control coil 24. However, when the drainage capacity estimation is performed while the air treatment device 54 is operating, it is not necessary to operate and stop the operation of the temperature control coil 24 individually in steps S51 and S53, and it is sufficient that the temperature control coil 24 is in the operating state corresponding to the inspection state.

[0126] Step S54 is a drainage time measurement step, and in step S54, the control unit 1 measures the time required to drain the amount of water discharged outside the machine, which changes depending on the construction state, the state of the equipment, etc., between the first water level detection means 35 and the second water level detection means 36.

[0127] In step S55, the water supply capacity calculation unit 10 of the control unit 1 calculates the water supply capacity Q in Drainage capacity Q out As in the third embodiment, the water supply / drainage capacity ratio K is calculated based on the measured water supply time T in and drainage time T out It is derived using equation (5).

[0128] In step S56, the control unit 1 outputs to the outside the device information measured or calculated in steps S52 to S55.

[0130] In step S57, the control unit 1 operates the intake air blower 26 to generate condensed water through cooling operation, and performs an operation of supplying water to the interior of the apparatus. In Fig. 16, the operation of step S57 is indicated by the phrase "intake air blower = ON". Note that, before the water supply operation is performed, the amount of water held in the drain pan 18 may be any amount as long as the first water level detection means 35 is not submerged in water.

[0131] In step S58, the control unit 1 determines whether the first water level detection means 35 is submerged or not. In Fig. 16, the operation of step S58 is indicated by the phrase "First water level detection means = submerged?" In the fourth embodiment, it is assumed that the first water level detection means 35 and the second water level detection means 36 are both electrode-type or float-type water level detection means, and therefore the input signals from the first water level detection means 35 and the second water level detection means 36 to the control unit 1 are signals indicating submersion that are detected when the water level, which is the height of the water accumulated in the drain pan 18, reaches an arbitrary water level, or signals indicating air that are detected when the arbitrary water level has not been reached.

[0132] When the control unit 1 determines that the first water level detection means 35 is not submerged (No in step S58), the operation of the control unit 1 returns to step S57, and the control unit 1 continues the water supply operation.

[0133] When the control unit 1 determines that the first water level detection means 35 is submerged (Yes in step S58), the operation of the control unit 1 proceeds to step S59.

[0134] In step S59, the timer unit 8 of the control unit 1 counts up the water supply time T in The timer unit 8 may directly count the time, or may count the number of times at an arbitrary cycle.

[0135] In step S60, the control unit 1 determines whether or not the second water level detection means 36 is submerged. In Fig. 16, the operation of step S60 is indicated by the phrase "Second water level detection means = submerged?"

[0136] When the control unit 1 determines that the second water level detection means 36 is not submerged (No in step S60), the operation of the control unit 1 returns to step S59, and the timer unit 8 of the control unit 1 counts up the water supply time T in Continue counting.

[0137] When the control unit 1 determines that the second water level detection means 36 is submerged (Yes in step S60), the operation of the control unit 1 proceeds to step S61.

[0138] In step S61, the control unit 1 stops the intake air blower 26 to terminate the generation of condensed water due to the cooling operation, and terminates the operation of supplying water to the interior of the aircraft. In Fig. 16, the operation of step S61 is indicated by the phrase "intake air blower = OFF".

[0139] FIG. 17 is a flowchart showing the procedure of drainage time measurement in drainage capacity estimation according to the fourth embodiment, and shows details of the drainage time measurement step S54 in FIG.

[0140] In step S62, the control unit 1 operates the drainage means 6 to perform the drainage operation to the outside of the apparatus. In Fig. 17, the operation of step S62 is indicated by the phrase "drainage means = ON".

[0141] In step S63, the control unit 1 judges whether or not the second water level detection means 36 is in the air. In Fig. 17, the operation of step S63 is indicated by the phrase "Second water level detection means = in the air?"

[0142] When the control unit 1 determines that the second water level detection means 36 is not in the air (No in step S63), the operation of the control unit 1 returns to step S62, and the control unit 1 continues to perform the drainage operation.

[0143] When the control unit 1 determines that the second water level detection means 36 is in the air (Yes in step S63), the operation of the control unit 1 proceeds to step S64.

[0144] In step S64, the timer unit 8 of the control unit 1 counts up the drainage time T out The timer unit 8 may directly count the time, or may count the number of times at an arbitrary cycle.

[0145] In step S65, the control unit 1 judges whether or not the first water level detection means 35 is in the air. In Fig. 17, the operation of step S65 is indicated by the phrase "First water level detection means = in the air?"

[0146] When the control unit 1 determines that the first water level detection means 35 is not in the air (No in step S65), the operation of the control unit 1 returns to step S64, and the timer unit 8 of the control unit 1 counts down the drain time T out Continue counting.

[0147] When the control unit 1 determines that the first water level detection means 35 is in the air (Yes in step S65), the operation of the control unit 1 proceeds to step S66.

[0148] In step S66, the control unit 1 stops the drainage means 6 to end the drainage operation to the outside of the apparatus. In Fig. 17, the operation of step S66 is indicated by the words "Drainage means = OFF".

[0149] By using the above sequence, the air treatment device 54 according to the fourth embodiment can calculate the ratio of the drainage capacity to the water supply capacity by actually measuring the water supply time and the water drainage time.

[0150] The control unit 1 of each embodiment from embodiment 1 to embodiment 4 will be further described. The control unit 1 outputs the acquired or determined information related to the state of the parts as output device information to the outside as a report or a signal. The control unit 1 judges whether or not maintenance of the water supply means 5 or the drainage means 6 is required and / or whether or not the operation state is normal based on preset information on whether or not maintenance is required or information on the normal operation range. When an instruction to periodically inspect the water supply means 5 or the drainage means 6 is set, the control unit 1 stores the state of the water supply means 5 or the drainage means 6 over time, and outputs an indication of when maintenance will be required as output device information to the outside as a report or a signal based on information on whether or not maintenance is required or information on the normal operation range.

[0151] The air treatment devices 51, 52, 53, 54 of the first to fourth embodiments may further include a remote controller capable of changing the content of the information on the necessity of maintenance or the information on the normal operating range. The information that can be changed by the remote controller includes at least one of the water supply capacity judgment threshold, the drainage capacity judgment threshold, the water supply / drainage capacity ratio judgment threshold, the drainage capacity inspection frequency, the schedule setting, and the inspection time required, which are used to notify that it is time to replace a part.

[0152] The air treatment devices 51, 52, 53, and 54 in the first to fourth embodiments are, for example, ventilation devices.

[0153] Embodiment 5. FIG. 18 is a functional block diagram showing the configuration of a ventilation device 55 according to the fifth embodiment. FIG. 18 shows an outline of the internal configuration of the control unit 1 and an outline of inputs and outputs to the control unit 1. The difference from FIG. 1 is that the air supply fan 26, the exhaust fan 28, and the temperature adjustment coil 24 are present as actuators 37 at the output destination of the output interface 3. The temperature adjustment coil 24 and the air supply fan 26 are actuators 37, not water supply means. The configuration of FIG. 18 is similar to the configurations of the first and second embodiments. The configuration in the case where a plurality of water level detection means 4 are installed is similar to the configurations of the third and fourth embodiments.

[0154] FIG. 19 is a schematic diagram showing the configuration of a ventilation device 55 according to the fifth embodiment. The ventilation device 55 has a casing 17. The casing 17 has a supply air intake duct 30 for drawing in outdoor air, a supply air blowing duct 31 for drawing in the supply air into the room, an exhaust air intake duct 32 for drawing in indoor air, and an exhaust air blowing duct 33 for exhausting the air to the outside. The ventilation device 55 further has a total heat exchanger 29 for performing total heat exchange between the outdoor air drawn into the supply air intake duct 30 and the indoor air drawn into the exhaust air intake duct 32, a temperature control coil 24 for heating the supply air, a humidifier 20 for humidifying the heated supply air, an exhaust fan 28, a supply air blower 26, a water level detection means 4, a water supply means 5, a drainage means 6, a drain pan 18, a control unit 1, and a remote controller 34. 19 is similar to the configurations of Embodiments 1 and 2. The configuration in the case where a plurality of water level detection means 4 are installed is similar to the configurations of Embodiments 3 and 4.

[0155] In the fifth embodiment, the operation of the ventilation device 55 and the output device information change according to the drainage capacity estimated in the first to fourth embodiments and the information set as maintenance information.

[0156] The microcomputer 7 can be set, by remote controller operation, as maintenance information, such as the lower limit of drainage capacity, the ratio of water supply / drainage capacity = drainage capacity / lower limit of water supply capacity, frequency of drainage capacity inspection, schedule setting, and information indicating the time required for inspection. For water supply capacity, the time to replace the water supply means 5 can be determined by setting an excess or deficiency value.

[0157] When settings regarding water supply capacity and drainage capacity are implemented, the ventilation device 55 compares the estimated water supply and drainage capacity with the set value, and if the estimated water supply and drainage capacity falls below the threshold value, or if there is a risk that it will fall below the threshold value at the time of the next scheduled inspection, it outputs to the outside as output device information indicating that it is time to replace the device.

[0158] In addition to the set value for notifying the time for replacement, a drainage capacity lower limit may be set for notifying a dangerous state in which there is a possibility of water leakage, such that the water supply / drainage capacity ratio becomes close to 1 or less, as an abnormality. In this case, since continued operation of the ventilation device 55 may lead to water leakage to the outside of the device, the ventilation device 55 can perform an operation to prevent water leakage to the outside of the device due to ventilation by stopping the intake air blower 26 and the exhaust air blower 28, or can perform a safety stop to prevent any more water from being supplied to the inside of the device by stopping the temperature control coil 24 and the water supply means 5. When the control unit 1 cannot operate the ventilation device 55, for example, the ventilation device 55 can notify the outdoor unit of the occurrence of an abnormality by a communication signal and stop the temperature control coil of the outdoor unit, thereby stopping the cooling operation of the ventilation device 55.

[0159] Even before the replacement target is reached, the ventilation device 55 performs protective operation by reducing the air volume of the air supply blower 26 and stopping, intermittently or reducing the output of the water supply means 5, etc., based on the safety factor for the drainage capacity that may cause water leakage, and continues the protective operation until it is confirmed that the drainage means 6 has been replaced and a safe drainage capacity has been restored. This makes it possible to prevent water leakage accidents and also promotes the implementation of maintenance, since normal operation cannot be achieved unless parts are replaced.

[0160] It is possible to set the inspection of the water supply and drainage capacity to be performed at any desired time interval, or to perform the inspection only when the ventilation device 55 receives an operation stop signal. The ventilation device 55 analyzes the tendency of the water supply and drainage capacity by storing the inspection results in the memory of the microcomputer 7, and outputs to the outside as output device information the time it takes to report an abnormality, and a guideline for when maintenance will be required, such as the estimated date and time.

[0161] When the required inspection time is set, it becomes possible to vary the control parameters that enable estimation of drainage capacity even if the drainage time, etc. is varied. Since the inspection can be performed in a short time by setting a short inspection time, it is possible to inspect the drainage capacity with minimal impact on the indoor environment even if the inspection timing occurs during normal operation due to the inspection period setting, etc.
