Description

Technical Field

[0001] This application relates to, but is not limited to, the field of humidification technology, specifically to a humidification device, air handling equipment, and control method and apparatus. Background Technology

[0002] As people's living standards improve and they pay more attention to quality of life, the demand for humidification is becoming increasingly strong, especially during the heating season or in western regions. Currently, most humidifiers use wet-film humidifiers, which have problems such as bacterial growth. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a humidification device and air handling equipment that uses electric heating of water to generate steam to meet humidification needs, which does not have the problem of bacterial growth and has a high degree of cleanliness.

[0004] This application provides a humidification device, including: a heating water tank, comprising a first heating tank and a second heating tank, the first heating tank being connected to the second heating tank and configured to heat water and supply water to the second heating tank, the second heating tank being configured to heat water to generate steam, and the second heating tank having a steam outlet; and a heating device, comprising a first heater and a second heater, the first heater being configured to heat water in the first heating tank, and the second heater being configured to heat water in the second heating tank.

[0005] The humidification device provided in this application embodiment uses heated water to generate steam to meet humidification needs, eliminating the problem of bacterial growth and ensuring high cleanliness. Furthermore, the heating water tank employs a two-stage design (including a first heating tank and a second heating tank) with zoned heating. This allows the water in the first heating tank to reach a higher temperature under the heating of the first heater, and then enters the second heating tank where it is heated to boiling and generates steam. This increases the inlet water temperature of the second heating tank, reduces temperature fluctuations, and thus improves the heat utilization rate of the heating device, thereby enhancing humidification efficiency.

[0006] This application also provides an air handling device, including: an air handling device body; and a humidifying device as described in any of the above embodiments, connected to the air handling device body, configured to deliver steam to the air handling device body, so that the air handling device body can output humid air.

[0022] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0023] like Figure 1 and Figure 3 As shown in the figure, this application provides a humidification device, including a heating water tank and a heating device.

[0024] like Figures 1 to 3 As shown, the heating water tank includes a first heating tank 11 and a second heating tank 12. The first heating tank 11 is connected to the second heating tank 12 and is configured to heat water and supply water to the second heating tank 12. The second heating tank 12 is configured to heat water and generate steam. The second heating tank 12 is provided with a steam outlet.

[0025] like Figures 1 to 3 As shown, the heating device includes a first heater 21 and a second heater 22. The first heater 21 is configured to heat the water in the first heating tank 11. The second heater 22 is configured to heat the water in the second heating tank 12.

[0026] The humidification device provided in this application embodiment uses heated water to generate steam to meet humidification needs, eliminating the problem of bacterial growth and ensuring high cleanliness. Furthermore, the heating water tank employs a two-stage design (including a first heating tank 11 and a second heating tank 12) with zoned heating. This allows the water in the first heating tank 11 to reach a higher temperature under the heating of the first heater 21. The heated water then enters the second heating tank 12 and is heated to boiling by the second heater 22, generating steam. This increases the inlet water temperature of the second heating tank 12, reduces water temperature fluctuations in the second tank, and thus improves the heat utilization rate of the heating device, thereby enhancing humidification efficiency.

[0027] It is understandable that in the process of heating water to generate steam in a humidifier, the heat is mainly divided into two parts: sensible heat and latent heat. The sensible heat primarily raises the water temperature, resulting in a relatively low steam production; the latent heat primarily causes a phase change in the water to generate steam, resulting in a higher steam production. Therefore, by adopting a two-stage water tank with zoned heating, the heat from the first heater 21 can be mainly used for the sensible heat, while the heat from the second heater 22 can be mainly used for the latent heat. This allows for the allocation of power between the first heater 21 and the second heater 22 based on the sensible and latent heat, facilitating full utilization of heat and thus improving humidification efficiency.

[0028] In some exemplary embodiments, such as Figures 1 to 3 As shown, the humidification device also includes a temperature sensor 51 and a liquid level sensor 52.

[0029] Temperature sensor 51 is configured to detect the water temperature in the first heating box 11, so as to reasonably control the start and stop of the first heater 21 based on the detection result of temperature sensor 51, so that the water temperature in the first heating box 11 can be maintained within a suitable temperature range, so as to avoid the heating time before the second heating box 12 produces steam being too long due to the water temperature of the first heating box 11 being too low, or the water temperature of the first heating box 11 being too high and boiling, thus wasting the heat of the first heater 21.

[0030] The liquid level sensor 52 is configured to detect the liquid level in the second heating tank 12, so as to reasonably control the start and stop of the water supply to the second heating tank 12 based on the detection result of the liquid level sensor 52, so that the liquid level in the second heating tank 12 can be maintained within a suitable liquid level range, so as to avoid the second heater 22 from burning dry due to the liquid level being too low or the heating time before steam is generated being too long due to the liquid level being too high.

[0031] Of course, a liquid level sensor 52 can also be installed in the first heating box 11 to detect the liquid level, and a temperature sensor 51 can also be installed in the second heating box 12 to detect the water temperature.

[0032] In some exemplary embodiments, such as Figures 1 to 3 As shown, the first heating tank 11 is connected to a first flow path 31 that can be switched on or off, and the first flow path 31 is configured to supply water to the first heating tank 11. The first heating tank 11 is connected to the second heating tank 12 through a second flow path 32 that can be switched on or off, and is configured to supply water to the second heating tank 12.

[0033] This facilitates automatic water supply to the first heating tank 11 and the second heating tank 12, eliminating the need for users to manually supply water to them, thus improving the user experience.

[0034] The first flow path 31 can be connected to a water supply component. The water supplied by the water supply component can be tap water or purified water. The water supply component can be a water storage tank 61 or a faucet or valve from an external water source 8.

[0035] The first heating chamber 11 may be provided with a first water outlet 111, and one end of the second flow path 32 is connected to the first water outlet 111. The second heating chamber 12 may be provided with a second water inlet, and the second flow path 32 may be connected to the second water inlet of the second heating chamber 12.

[0036] Alternatively, the second flow path 32 may not be directly connected to the second heating box 12. For example, the outlet of the second flow path 32 may be located inside the second heating box 12, directly outputting water into the second heating box 12; or the top of the second heating box 12 may be open, and the outlet of the second flow path 32 may be suspended at the top opening of the second heating box 12.

[0037] The lengths of the first flow path 31 and the second flow path 32 are not restricted.

[0038] In some embodiments, such as Figures 1 to 3 As shown, the humidification device also includes a first water inlet valve 41 and a second water inlet valve 42.

[0039] The first inlet valve 41 is located in the first flow path 31 and is configured to control the opening and closing of the first flow path 31. The second inlet valve 42 is located in the second flow path 32 and is configured to control the opening and closing of the second flow path 32.

[0040] The first inlet valve 41 can be, but is not limited to, a solenoid valve, and the second inlet valve 42 can be, but is not limited to, a solenoid valve. This facilitates the automated control of the first inlet valve 41 and the second inlet valve 42, and helps to improve the intelligence level of the humidification device.

[0041] In some exemplary embodiments, such as Figure 1 and Figure 3 As shown, the humidification device also includes a water storage tank 61, a third flow path 33, a third water inlet valve 43, and a pressure regulating valve 44.

[0042] The water storage tank 61 is connected to the first heating box 11 through the first flow path 31 and is configured to supply water to the first heating box 11. The first heating box 11 may be provided with a first water inlet, and the first flow path 31 is connected to the first water inlet.

[0043] The third flow path 33 is configured to connect the water storage tank 61 with the external water source 8, and is configured to supply water to the water storage tank 61. The water provided by the external water source 8 can be tap water or purified water.

[0044] The third inlet valve 43 and the pressure regulating valve 44 are located in the third flow path 33. The third inlet valve 43 is configured to control the opening and closing of the third flow path 33. The pressure regulating valve 44 is configured to stabilize the water pressure in the third flow path 33, so as to prevent excessive water pressure from affecting the normal operation of the third flow path 33 and subsequent components.

[0045] In some embodiments, such as Figure 1 and Figure 3 As shown, the humidification device also includes a mechanical water level control switch 62 and a high / low water level control switch 63. The high / low water level control switch 63 is configured to control the automatic opening and closing of the third water inlet valve 43, so that the water level in the water storage tank 61 can be maintained between the set minimum and maximum water levels. The mechanical water level control switch 62 can function as a water level switch in the event that the high / low water level control switch 63 fails, thus achieving double protection.

[0046] In some exemplary embodiments, such as Figure 1 and Figure 3 As shown, the humidification device also includes a water receiving tray 7 located on the lower side of the heating water tank.

[0047] The second heating chamber 12 is provided with a second water outlet, which is connected to the water receiving tray 7 through a drainage path 34. The drainage path 34 is provided with a drain valve 45, which is configured to control the opening and closing of the drainage path 34.

[0048] Once the humidification process is complete, the drain valve 45 can be opened to drain the water from the first heating tank 11 and the second heating tank 12, preventing water from accumulating in the heating tank for a long time and causing bacteria to grow.

[0049] The water storage tank 61 can also be connected to the water receiving tray 7 via the drain path 34. After the humidification process is complete, the drain valve 45 can be opened to drain the water in the water storage tank 61, preventing water from accumulating in the water storage tank 61 for a long time and causing bacterial growth. The drain path 34 of the water storage tank 61 and the drain path 34 of the heating water tank can share a drain valve 45, or they can be equipped with separate drain valves 45.

[0050] The drain valve 45 can be, but is not limited to, a solenoid valve. The water tray 7 can be equipped with a drain outlet 71, through which water is drained to an outdoor space or other location.

[0051] In some exemplary embodiments, the volume of the first heating chamber 11 is smaller than the volume of the second heating chamber 12. The heating area of ​​the second heater 22 is larger than the heating area of ​​the first heater 21. For example, the first heater 21 can be a tubular or rod-shaped heater, and the second heater 22 can be a plate-shaped heater.

[0052] This helps to increase the humidification capacity and heating rate of the second heating chamber 12, thereby improving the humidification efficiency.

[0053] In some exemplary embodiments, such as Figures 1 to 3 As shown, the first heating box 11 is located inside the second heating box 12. This makes the structure of the heating water tank more regular and facilitates the installation of the humidification device.

[0054] The first heating box 11 is provided with a first water inlet, which is located on the bottom wall or side wall of the first heating box 11. This makes it easy to use gravity to drain the water in the first heating box 11 into the second heating box 12 without the need to install an additional power source such as a water pump.

[0055] Of course, the first heating box 11 can also be located outside the second heating box 12. The first water inlet can also be located on top of the first heating box 11.

[0056] In some exemplary embodiments, such as Figures 1 to 3 As shown, the humidification device also includes a steam flow path 35 and a steam valve 46.

[0057] Steam flow path 35 is connected to a steam outlet. The outlet of steam flow path 35 can be directly connected to the indoor space, or it can be connected to the main body of the air handling unit or other air handling units, through which steam is supplied to the indoor space.

[0058] Steam valve 46 is located in steam flow path 35 and is configured to control the on / off state of steam flow path 35. Steam valve 46 can be, but is not limited to, a solenoid valve.

[0059] This application also provides an air handling device (not shown in the figures), including: an air handling device body and a humidifying device as described in any of the above embodiments. The humidifying device is connected to the air handling device body and configured to supply steam to the air handling device body, enabling the air handling device body to output humidified air.

[0060] The air handling equipment provided in this application includes the humidification device of any of the above embodiments, and therefore has all the above-mentioned beneficial effects, which will not be repeated here.

[0061] Air handling equipment can be air conditioners, air purifiers, sterilizers, and other devices with air handling functions.

[0062] When the air handling unit is an air conditioner, it can be a split-type air conditioner, in which case the humidifier is connected to the indoor unit of the split-type air conditioner. Alternatively, it can be an integrated air conditioner.

[0063] The main body of the air handling unit may be equipped with a humidification port, and the steam outlet of the humidification device is connected to the humidification port.

[0064] This application also provides a control method for the humidification device in any of the above embodiments. For example... Figure 4 As shown, the control methods include:

[0065] Step S202: In response to the humidification command, the first heater 21 is activated to heat the water in the first heating chamber 11;

[0066] Step S204: Start the second heater 22 to heat the water in the second heating box 12, so that steam is output from the steam outlet.

[0067] The control method provided in this application uses heated water to generate steam to meet humidification needs, eliminating the problem of bacterial growth and ensuring high cleanliness. Furthermore, the heating water tank employs a two-stage design (including a first heating tank 11 and a second heating tank 12) with zoned heating. This allows the water in the first heating tank 11 to reach a higher temperature under the heating of the first heater 21. The heated water then enters the second heating tank 12 and is heated to boiling by the second heater 22, generating steam. This increases the inlet water temperature of the second heating tank 12, reduces water temperature fluctuations, and thus improves the heat utilization rate of the second heater 22, thereby enhancing humidification efficiency.

[0068] The humidification command can be triggered by the user or automatically issued when the indoor humidity is below a set threshold.

[0069] In some exemplary embodiments, the first heating tank 11 is connected to a switchable first flow path 31, which is configured to supply water to the first heating tank 11. The first heating tank 11 is connected to a second heating tank 12 via a switchable second flow path 32, which is configured to supply water to the second heating tank 12.

[0070] like Figure 5 As shown, the control method also includes:

[0071] Before starting the first heater 21 to heat the water in the first heating tank 11, the first flow path 31 is opened to supply water to the first heating tank 11;

[0072] Before starting the second heater 22 to heat the water in the second heating tank 12, the second flow path 32 is opened to supply water to the second heating tank 12.

[0073] This allows for automatic water supply to the first heating tank 11 and the second heating tank 12, eliminating the need for users to manually supply water to them and improving the user experience.

[0074] In some exemplary embodiments, the control method further includes:

[0075] Obtain the water temperature inside the first heating tank 11;

[0076] The first heater 21 is controlled to operate intermittently so that the water temperature in the first heating tank 11 can be maintained within the set temperature range.

[0077] This allows for reasonable control of the start and stop of the first heater 21 based on the water temperature in the first heating box 11, ensuring that the water temperature in the first heating box 11 is maintained within a suitable temperature range. This avoids the heating time before the second heating box 12 produces steam being too long due to the water temperature in the first heating box 11 being too low, or the water temperature in the first heating box 11 being too high, causing boiling and wasting the heat of the first heater 21.

[0078] The water temperature inside the first heating box 11 can be obtained through the temperature sensor 51 of the first heating box 11.

[0079] In some embodiments, such as Figure 5 As shown, controlling the first heater 21 to operate intermittently, so that the water temperature in the first heating tank 11 can be maintained within a set temperature range, includes:

[0080] Based on the water temperature in the first heating box 11 rising to T1+△T, the first heater 21 is controlled to be turned off;

[0081] When the water temperature in the first heating chamber 11 drops to T1-△T, the first heater 21 is turned on.

[0082] The set temperature range can be, but is not limited to, 55°C to 85°C. T1 can be, but is not limited to, 70°C, and ΔT can be, but is not limited to, 15°C. Within this temperature range, the tolerance range of the surface temperature of the PTC heater is relatively small.

[0083] In some exemplary embodiments, the control method further includes:

[0084] Obtain the liquid level in the second heating tank 12;

[0085] The second flow path 32 is intermittently opened to maintain the liquid level in the second heating box 12 within the set liquid level range.

[0086] This allows for reasonable control of the water supply to the second heating tank 12 based on the liquid level in the second heating tank 12, ensuring that the liquid level in the second heating tank 12 is maintained within a suitable range. This prevents the second heater 22 from burning dry due to an excessively low liquid level or from taking too long to heat before steam is produced due to an excessively high liquid level.

[0087] The liquid level in the second heating box 12 can be obtained through the liquid level sensor 52.

[0088] In some embodiments, such as Figure 5 As shown, the second flow path 32 is intermittently switched on to maintain the liquid level in the second heating tank 12 within a set range, including:

[0089] Based on the rise of the liquid level in the first heating box 11 to H1+△H2, the second flow path 32 is disconnected.

[0090] When the liquid level in the first heating box 11 drops to H1-△H1, the second flow path 32 is controlled to open.

[0091] The second flow path 32 can be disconnected by closing the second inlet valve 42. The second flow path 32 can be opened by opening the second inlet valve 42.

[0092] The values ​​of H1, ΔH1, and ΔH2 are not limited and can be set reasonably according to the size of the second heating box 12. ΔH1 can be greater than ΔH2, which can prevent the second heater 22 from burning dry and also allow the second heater 22 to start heating earlier when the liquid level in the second heating box 12 is low, thereby reducing the waiting time before steam is produced.

[0093] In some exemplary embodiments, the control method further includes:

[0094] Based on the fact that the first heating tank 11 is full of water, the first flow path 31 is disconnected; or

[0095] Based on the first set duration of the first flow path 31 being turned on, the first flow path 31 is controlled to be turned off.

[0096] In other words, the first flow path 31 can be automatically disconnected when the first heating tank 11 is full of water, or it can be automatically disconnected when the first set time is reached. The opening and closing of the first flow path 31 can be achieved by opening and closing the first water inlet valve 41. The first set time can be, but is not limited to, 30 minutes.

[0097] Therefore, by controlling the liquid level of the second heating tank 12 and the water temperature of the first heating tank 11, the start and stop of the second water inlet valve 42 and the first heater 21 can be adjusted, thus achieving dynamic heating balance.

[0098] In some exemplary embodiments, such as Figure 5 As shown, the control method also includes:

[0099] Before opening the first flow path 31 to supply water to the first heating box 11, determine the target humidity;

[0100] After the second heater 22 is activated to heat the water in the second heating box 12 and steam is output from the steam outlet, the first heater 21 and the second heater 22 are turned off based on the determination that the indoor humidity has reached the target humidity.

[0101] The target humidity can be determined by external input information. For example, users can input the target humidity through a remote control, a mobile terminal (such as a mobile phone, computer, iPad, or smart band) app, or the machine's control panel.

[0102] Alternatively, the target humidity can be determined using internally stored information. For example, the target humidity can be a pre-set target humidity at the factory, or a target humidity previously set by the user.

[0103] Once the target humidity is reached, turn off the first heater 21 and the second humidifier to end the humidification process.

[0104] The target humidity can be in the range of, but is not limited to, 40% to 60%.

[0105] In some exemplary embodiments, such as Figure 5 As shown, the control method further includes: after starting the second heater 22 to heat the water in the second heating box 12, acquiring the indoor humidity at second set intervals and determining whether the indoor humidity has reached the target humidity.

[0106] In some embodiments, the indoor humidity is determined to reach the target humidity based on d1-Δd≤d≤d1+Δd. d represents the indoor humidity, and d1 represents the target humidity. d1 can be in the range of, but is not limited to, 40% to 60%, and Δd can be, but is not limited to, 2%.

[0107] Indoor humidity can be obtained through humidity sensor 9. Humidity sensor 9 can be installed in the humidifier, the main body of the air handling unit, or other locations.

[0108] In some exemplary embodiments, the input power ratio of the first heater 21 to the second heater 22 is in the range of 1:9 to 3:7.

[0109] During humidification, the power supply allocates power to the first heater 21 and the second heater 22, with the power allocation ratio ranging from 1:9 to 3:7. In other words, the power allocated to the first heater 21 is less than that allocated to the second heater 22 because the heat from the first heater 21 is mainly used for the sensible heat portion, requiring less power; while the heat from the second heater 22 is mainly used for the latent heat portion, requiring more power. This improves heat utilization and humidification efficiency.

[0110] The first heater 21 can be, but is not limited to, a PTC heater, and the second heater 22 can be, but is not limited to, a PTC heater.

[0120] In any one or more of the exemplary embodiments described above, the described functionality may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functionality may be stored as one or more instructions or code on or transmitted via a computer-readable medium and executed by a hardware-based processing unit. The computer-readable medium may comprise a computer-readable storage medium corresponding to a tangible medium such as a data storage medium, or a communication medium comprising any medium facilitating the transfer of a computer program from one place to another, for example, according to a communication protocol. In this manner, a computer-readable medium may generally correspond to a non-transitory tangible computer-readable storage medium or a communication medium such as a signal or carrier wave. The data storage medium may be any available medium accessible by one or more computers or one or more processors to retrieve instructions, code, and / or data structures for implementing the techniques described in this disclosure. Computer program products may comprise computer-readable media.

[0121] For example, and not as a limitation, such computer-readable storage media may include RAM, ROM, EEPROM, CD-ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, flash memory, or any other medium that can be used to store desired program code in the form of instructions or data structures and is accessible by a computer. Furthermore, any connection may also be referred to as a computer-readable medium. For example, if instructions are transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of medium. However, it should be understood that computer-readable storage media and data storage media do not include connections, carrier waves, signals, or other transient media, but rather refer to non-transient tangible storage media. As used herein, disks and optical discs include compact optical discs (CDs), laser discs, optical discs, digital versatile discs (DVDs), floppy disks, or Blu-ray discs, where disks typically reproduce data magnetically, while optical discs use lasers to reproduce data optically. The above combinations should also be included within the scope of computer-readable media.

[0122] For example, instructions can be executed by one or more processors, such as one or more digital signal processors (DSPs), general-purpose microprocessors, application-specific integrated circuits (ASICs), field-programmable logic arrays (FPGAs), or other equivalent integrated or discrete logic circuits. Therefore, the term "processor" as used herein can refer to any of the above-described structures or any other structures suitable for implementing the techniques described herein. Additionally, in some aspects, the functionality described herein can be provided within dedicated hardware and / or software modules configured for encoding and decoding, or incorporated into combined codecs. Furthermore, the techniques can be fully implemented in one or more circuit or logic elements.

[0123] The technical solutions of the embodiments of this disclosure can be implemented in a wide variety of devices or equipment, including wireless mobile phones, integrated circuits (ICs), or a set of ICs (e.g., chipsets). Various components, modules, or units are described in the embodiments of this disclosure to emphasize functional aspects of a device configured to perform the described techniques, but they do not necessarily need to be implemented through different hardware units. Rather, as described above, the various units can be combined in codec hardware units or provided by a collection of interoperable hardware units (including one or more processors as described above) combined with suitable software and / or firmware.
