Abstract

The present invention discloses a humidification and purification all-in-one machine with a stepped atomizing device and a humidification and purification method thereof. The machine is provided with an inclined stepped ultrasonic atomizing device in the air supply area, including a stepped atomizing box and an ultrasonic atomizing sheet. The stepped atomizing box includes a multi-stage atomizing unit with an upward opening. The outer side of each atomizing unit is provided with a baffle, and the bottom surface is an inclined surface and is respectively fixed with an ultrasonic atomizing sheet. The side wall of the highest atomizing unit is provided with a water inlet, and the side of the lowest atomizing unit is provided with an overflow trough. The humidification and purification method is that under the action of the ultrasonic atomizing device, an upward-sloping water mist column is formed in each atomizing unit. At the same time, the fan assembly sends out the purified airflow, and the airflow is also transported in an upward-sloping manner. The airflow carries water mist and is sent out during the rising process. The airflow also prompts the water mist column in each atomizing unit to hit the atomizing unit of the upper level, forming a water backflow effect. The present invention can effectively improve the humidification balance in the space and reduce energy consumption.

Description

Technical Field

[0001] The present invention relates to the technical field of household appliance manufacturing, and in particular to a humidification and purification all-in-one machine with a stepped atomization device and a humidification and purification method thereof. Background Art

[0002] In traditional household appliances, indoor air purification and humidification are usually achieved by using two independent purifiers and humidifiers. With the development of science and technology, integrated devices with both humidification and purification functions have gradually appeared on the market. However, these devices are prone to the following defects during use: (1) Most existing humidification and purification all-in-one machines are fogless humidification and purification all-in-one machines. During use, there is a high risk of secondary pollution caused by the humidification cloth becoming smelly and moldy. The humidification cloth or humidification paper needs to be replaced regularly, which increases the user's cost. At the same time, the humidification capacity of cold evaporation fogless humidification is proportional to the air volume. Therefore, the humidification capacity of fogless humidification and purification all-in-one machines is actually limited. (2) Currently, integrated air conditioners also often have a humidification function, but due to their complex structure, it is difficult to clean the humidification water body and the humidification tank and other structures. (3) There are also humidification and purification all-in-one machines that use ultrasonic atomization, but due to the unreasonable structural design of the ultrasonic atomization device, it is easy to have uneven humidity in the space, slow humidification speed, unclear humidification effect, and high energy consumption during the humidification process. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a humidification and purification integrated machine with a stepped atomization device. The device has both humidification and purification functions, which can effectively improve the humidification balance in the space, reduce energy consumption, and improve user experience.

[0004] Another object of the present invention is to provide a humidification and purification method for the above-mentioned humidification and purification integrated machine with a stepped atomization device.

[0005] The technical solution of the present invention is: a humidifier and purifier with a stepped atomization device, an ultrasonic atomization device is provided in the air supply area formed between the outlet of the fan assembly and the main air outlet of the equipment; the ultrasonic atomization device is an inclined stepped structure, including a stepped atomization box and an ultrasonic atomization sheet, the stepped atomization box includes a multi-stage atomization unit with an opening facing upward, a baffle is provided on the outer side of each stage of the atomization unit, the bottom surface of each stage of the atomization unit is an inclined surface, and an ultrasonic atomization sheet is fixed on the bottom surface of each stage of the atomization unit, a water inlet is provided on the side wall of the atomization unit at the highest position, and an overflow trough is provided on one side of the atomization unit at the lowest position. Among them, the use of an inclined stepped atomization device can make the water mist column formed after atomization be inclined upward, consistent with the direction of the air flow in the air supply area. On the one hand, the air flow can carry the water mist out of the main air outlet of the equipment without increasing the wind resistance. On the other hand, it can prompt the water mist columns in the atomization units at each level to hit the atomization unit of the next level, thereby forming a water reflux effect in the stepped atomization box to reduce the energy consumption of the wet purification all-in-one machine.

[0006] In the air supply area, the direction of the air flow is generally inclined upward. Along the upward direction of the air flow, the heights of the atomization units at each level in the stepped atomization box gradually increase, and the atomization unit at the lowest position is arranged outside the longitudinal air duct at the outlet of the fan assembly.

[0007] The stepped atomizer box includes three levels of atomizer units, which are, from the highest position to the lowest position, the first-level atomizer unit, the second-level atomizer unit, and the third-level atomizer unit. The bottom surfaces of the atomizer units at each level are tilted inward (that is, the tilt direction of the bottom surface of the atomizer unit from the high end to the low end is consistent with the tilt direction of the airflow in the air supply area, so that the rising direction of the water mist column formed on the atomizer units at each level is also tilted upward as a whole, consistent with the airflow), and the tilt angle is 3 to 8 degrees. Among them, the first-level atomizer unit is located at the highest position, and the water inlet of the entire stepped atomizer box is provided in the first-level atomizer unit. The third-level atomizer unit is located at the lowest position, and the overflow trough of the entire stepped atomizer box is provided on the outside of the third-level atomizer unit. At the same time, a float is also provided in the third-level atomizer unit for monitoring the water level in the third-level atomizer unit, and is used in conjunction with the control system of the humidifier-purifier to determine the start or stop of the water pump to ensure that the amount of water in the entire stepped atomizer box is appropriate. A baffle of the first-stage atomization unit is provided at the junction of the first-stage atomization unit and the second-stage atomization unit, a baffle of the second-stage atomization unit is provided at the junction of the second-stage atomization unit and the third-stage atomization unit, and a baffle of the third-stage atomization unit is provided on the side of the third-stage atomization unit close to the following longitudinal air duct. The bottom surface of the first-stage atomization unit gradually decreases in height from the side close to the baffle to the other side to form an inclined surface. Similarly, the bottom surfaces of the second-stage atomization unit and the third-stage atomization unit also gradually decrease in height from the side close to the baffle to the other side to form an inclined surface. The ultrasonic atomizer is fixedly installed on the inclined surface. Therefore, the water mist column formed after atomization will also be inclined upward, and its upward direction is consistent with the direction of the airflow in the air supply area. In this case, the water mist column itself and the driving effect of the airflow work together to make the water mist column in the third-stage atomization unit hit the second-stage atomization unit, and the water mist column in the second-stage atomization unit hit the first-stage atomization unit, thereby forming a water reflux effect in the stepped atomization box, which can effectively reduce the working times of the water pump, improve the recycling of overflow water, and reduce the energy consumption of the humidification and purification machine.

[0008] In addition, an air quality indicator light and an air quality detection sensor can be set in the stepped atomization box. Under the control of the control system of the humidifier and purifier, real-time monitoring of air quality can be achieved, and the user can be reminded by the color change of the air quality indicator light. At the same time, the air quality indicator light is illuminated in the water mist, and the color of the water mist can be observed from the main air outlet of the equipment, which can effectively enhance the user's fun and experience.

[0009] The humidification and purification all-in-one of the present invention also includes a shell, a water tank, a water pump, a water pipe, a fan assembly and an air purification assembly.

Among them, the water tank supplies water to the ultrasonic atomization device through the water pump and the water pipe, and the water droplets formed in the air supply area and the water overflowed from the ultrasonic atomization device through the overflow trough all fall back into the water tank, forming a recyclable mode. Furthermore, the top surface of the shell is also provided with a control panel of the humidification and purification all-in-one, the control panel is provided on one side of the air outlet grille, and a circuit board is also provided in the shell, and the circuit board is provided in the gap between the outside of the ultrasonic atomization device and the shell. The fan assembly adopts a double-suction centrifugal fan, and is equipped with air purification components on both sides. The double-suction centrifugal fan draws air on both sides and blows the purified air out from the middle and lower part of the shell (i.e. the air outlet of the air guide cover). When the air flow goes up, it passes through the stepped atomization area (i.e. the air supply area above the stepped atomization box), and can bring the mist generated in multiple atomization units out of the shell, thereby achieving the effect of humidifying the environment with purified air. At the same time, it can also achieve large fog output, so that the fog is effectively stirred in the space and the humidity is balanced.

[0010] The fan assembly includes a wind wheel, a drive motor, and an air guide cover. The drive motor is installed in the housing through a fixing plate. The center of the wind wheel is connected to the power output shaft of the drive motor. The wind wheel is arranged in the air guide cover. The two sides of the air guide cover are respectively connected to the air purification component and the main air inlet of the equipment. The open end of the air guide cover is the air outlet of the fan assembly. The air outlet and the inner wall of the housing form a longitudinal air duct. The stepped atomizer box is installed above the air guide cover. The longitudinal air duct extends upward and connects with the area above the stepped atomizer box to form an air supply area. Among them, the lowest atomizer unit of the stepped atomizer box is located above the air outlet of the fan assembly, that is, on one side of the longitudinal air duct.

[0011] The longitudinal air duct is further provided with a flow guiding structure, and the side of the flow guiding structure facing the air supply area is a smooth curved surface, which can effectively guide the direction of the air flow.

[0012] A drain outlet communicated with the water tank is provided at the bottom of the longitudinal air duct, and an air guide cover drain trough communicated with the water tank is also provided at the bottom of the air guide cover.

[0013] The outside of the air purification component is provided with an air inlet filter serving as the main air inlet of the equipment, and the inside of the air inlet filter is provided with a first activated carbon layer and a HEPA (high-efficiency air filter) in sequence. The air inlet filter, the first activated carbon layer and the HEPA constitute the air purification component.

[0014] The water tank is provided with a water purification component, which includes a medical stone layer, a silver ion cotton layer, a second activated carbon layer and a filter material cover arranged in sequence from bottom to top; a water pipe includes a pumping pipe and a water supply pipe, the water inlet end of the pumping pipe is connected to the water purification component, the water outlet end of the pumping pipe is connected to a water pump, the water inlet end of the water supply pipe is connected to the water pump outlet, and the water outlet end of the water supply pipe is connected to the water inlet of the stepped atomization box. The water tank can adopt a drawer-type structure, which is convenient for users to replace or add water. The water purification component is designed as a concealed structure in the water tank. After the water in the water tank is filtered in sequence by the medical stone layer, the silver ion cotton layer and the second activated carbon layer, it is extracted by the pump through the pumping pipe and delivered to the ultrasonic atomization device through the water supply pipe.

[0015] The present invention provides a humidification and purification method for the above-mentioned humidification and purification integrated machine with a stepped atomization device, which is specifically as follows: in the ultrasonic atomization device, in the stepped atomization box, after water enters the highest atomization unit from the water inlet, as the water level in the highest atomization unit rises, the water overflows to the atomization unit of the next level after it is full, and then overflows step by step until the lowest atomization unit is also full of water, and the excess water is discharged from the overflow trough; the ultrasonic atomization sheets in the atomization units at each level atomize the water in the atomization unit to form a water mist column that tilts upward, and at the same time, the fan assembly sends water to the air supply area The purified air flow is sent out from the domain, and the air flow is also transported in an inclined upward manner. On the one hand, the water mist in the water mist column is carried along with the water mist in the rising process and sent to the main air outlet of the equipment to form humidified and purified air (realizing large-volume fog output, so that the fog is effectively stirred in the space and its humidity is more balanced). On the other hand, the air flow also prompts the water mist column in each atomization unit to hit the atomization unit of the upper level, thereby forming a water reflux effect in the stepped atomization box (which can effectively reduce the working times of the water pump and improve the recycling rate of overflow water).

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this all-in-one humidifier and purification machine with a stepped atomizing device and its use method, a stepped ultrasonic atomizing device with an inclined surface is arranged in the air supply area, and its inclination is utilized to make the water mist column formed after atomization present an inclined upward state and be consistent with the direction of the air flow formed after purification. On the one hand, the purified air flow is utilized to bring the mist generated in each atomizing unit out of the shell, thereby realizing large-volume fog transportation, so that the mist is effectively stirred in the space and its humidity balance is improved. On the other hand, the air flow is utilized to prompt the water mist column in each atomizing unit to hit the atomizing unit of the upper level, thereby forming a water reflux effect in the stepped atomizing box, which can effectively reduce the working times of the water pump and improve the recycling rate of overflow water, thereby achieving the purpose of reducing energy consumption.

[0018] In this integrated humidifier and purifier with a stepped atomization device, each atomization unit in the stepped atomization box and the corresponding ultrasonic atomization piece can work simultaneously or separately, thereby adjusting the amount of water mist and the air humidity at the total air outlet of the equipment.

[0019] In this integrated humidifier and purifier with a stepped atomizing device, the water tank is arranged at the bottom of the shell, which can maximize the volume of the water tank and thus achieve a large humidification capacity; at the same time, the water adding method in the ultrasonic atomizing device adopts a convenient top-up water adding method, through the natural overflow formed between the atomizing units at different positions and heights, and the excess water can also be returned to the water tank through the overflow tank, which can greatly reduce the working power required for the water pump, and the water can also be recycled to achieve the purpose of environmental protection and energy saving.

[0020] In actual application, this all-in-one humidifier and purifier with a stepped atomization device can allow users to experience the purified and humidified air, giving them a comfortable feeling of sunshine after rain.

DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to the examples, but the embodiments of the present invention are not limited thereto.

[0027] Example

[0028] This embodiment is a humidifier and purifier with a stepped atomization device. Figure 2 or Figure 3 As shown, it includes a housing 1, a water tank 2, a water pump 3, a water pipe (including a water supply pipe 4 and a water extraction pipe 5), a fan assembly (including a wind wheel 6, a drive motor 7, and an air guide hood 8), an air purification assembly (including an air inlet filter 9, a first activated carbon layer 10, and a HEPA 11) and an ultrasonic atomization device (including a stepped atomization box 12 and an ultrasonic atomization sheet 13). Its specific structure is as follows:

[0029] In the humidification and purification integrated machine, Figure 3 or Figure 4 As shown, an ultrasonic atomizing device is provided in the air supply area 14 formed between the outlet of the fan assembly and the main air outlet of the equipment; the ultrasonic atomizing device is in an inclined stepped structure, including a stepped atomizing box and an ultrasonic atomizing sheet. The stepped atomizing box includes a multi-stage atomizing unit with an upward opening, and a baffle 15 is provided on the outer side of each atomizing unit. The bottom surface of each atomizing unit is an inclined surface, and an ultrasonic atomizing sheet is fixed on the bottom surface of each atomizing unit. The side wall of the atomizing unit at the highest position is provided with a water inlet 16, and the side of the atomizing unit at the lowest position is provided with an overflow trough 17. Among them, by utilizing the inclined stepped atomizing device, the water mist column formed after atomization can be inclined upward, consistent with the direction of the airflow in the air supply area. On the one hand, the airflow can carry the water mist out of the main air outlet of the equipment without increasing the wind resistance. On the other hand, it can prompt the water mist columns in the atomizing units at each level to hit the atomizing unit of the upper level, thereby forming a water reflux effect in the stepped atomizing box to reduce the energy consumption of the wet purification all-in-one machine. As shown Figure 4As shown, in the air supply area, the direction of the air flow is tilted upward as a whole. Along the direction of the air flow tilting upward, the height of the atomizing units at each level in the stepped atomizing box is gradually increased, and the atomizing unit at the lowest position is arranged on the outside of the longitudinal air duct 14-1 at the outlet of the fan assembly (the longitudinal air duct and the area above the stepped atomizing box together constitute the air supply area). As a preferred embodiment, the stepped atomizing box includes three levels of atomizing units, which are, from the highest position to the lowest position, the first-level atomizing unit 18, the second-level atomizing unit 19 and the third-level atomizing unit 20, respectively. The bottom surfaces of the atomizing units at each level are tilted inward (that is, the tilt direction of the bottom surface of the atomizing unit from the high end to the low end is consistent with the tilt direction of the air flow in the air supply area, so that the rising direction of the mist formed on the atomizing units at each level is also tilted upward as a whole, consistent with the air flow), and the tilt angle a is 5° (depending on the actual specifications and needs of the humidification and purification all-in-one machine, it can also be selected within the range of 3 to 8°). Among them, the first-stage atomization unit is located at the highest position, the water inlet of the entire stepped atomization box is arranged in the first-stage atomization unit, the third-stage atomization unit is located at the lowest position, and the overflow tank of the entire stepped atomization box is arranged in the third-stage atomization unit. At the same time, a float 29 is also provided in the third-stage atomization unit to monitor the water level in the third-stage atomization unit, and to cooperate with the control system of the humidification and purification all-in-one machine to determine the start or stop of the water pump to ensure that the amount of water in the entire stepped atomization box is appropriate. A baffle of the first-stage atomization unit is provided at the junction of the first-stage atomization unit and the second-stage atomization unit, a baffle of the second-stage atomization unit is provided at the junction of the second-stage atomization unit and the third-stage atomization unit, and a baffle of the third-stage atomization unit is provided on the side of the third-stage atomization unit close to the following longitudinal air duct. The bottom surface of the first-stage atomization unit gradually decreases in height from the side close to the baffle to the other side to form an inclined surface. Similarly, the bottom surfaces of the second-stage atomization unit and the third-stage atomization unit also gradually decrease in height from the side close to the baffle to the other side to form an inclined surface. The ultrasonic atomizer is fixedly mounted on an inclined surface. Therefore, the water mist column formed after atomization will also form an upward tilt, and its upward tilt direction is consistent with the direction of the airflow in the air supply area. In this case, the water mist column's own action and the driving effect of the airflow will work together to cause the water mist column in the third-stage atomization unit to be ejected into the second-stage atomization unit, and the water mist column in the second-stage atomization unit to be ejected into the first-stage atomization unit, thereby forming a water backflow effect in the stepped atomization box, which can effectively reduce the number of pump operations, improve the recycling of overflow water, and reduce the energy consumption of the humidifier-purifier. In addition, an air quality indicator light and an air quality detection sensor can be set in the stepped atomization box. Under the control of the humidifier-purifier control system, real-time monitoring of air quality can be achieved, and the user can be reminded by the color change of the air quality indicator light. At the same time, the air quality indicator light is illuminated in the water mist, and the color of the water mist can be observed from the main air outlet of the device, which can effectively enhance the user's enjoyment and experience.

Furthermore, a control panel 27 of the humidification and purification all-in-one is also provided on the top surface of the shell. The control panel is provided on one side of the air outlet grille. A circuit board 28 is also provided in the shell. The circuit board is provided in the gap between the outside of the ultrasonic atomizing device and the shell. The fan assembly adopts a double-suction centrifugal fan, and is equipped with air purification components on both sides. The double-suction centrifugal fan draws air on both sides and blows the purified air out from the middle and lower part of the shell (i.e. the air outlet of the air guide cover). When the air flow goes up, it passes through the stepped atomization area (i.e. the air supply area above the stepped atomization box), and can bring the mist generated in multiple atomization units out of the shell, thereby achieving the effect of humidifying the environment with purified air. At the same time, it can also achieve large fog output, so that the fog is effectively stirred in the space and the humidity is balanced.

[0031] like Figure 2 As shown, the fan assembly includes a wind wheel, a drive motor and an air guide cover. The drive motor is installed in the shell through a fixing plate 30. The center of the wind wheel is connected to the power output shaft of the drive motor. The wind wheel is arranged in the air guide cover. The two sides of the air guide cover are respectively connected to the air purification assembly and the main air inlet of the equipment. The open end of the air guide cover is the air outlet of the fan assembly. A longitudinal air duct is formed between the air outlet and the inner wall of the shell. The stepped atomizer box is installed above the air guide cover. After extending upward, the longitudinal air duct is connected to the area above the stepped atomizer box to form an air supply area. Among them, the lowest atomizer unit of the stepped atomizer box is located above the air outlet of the fan assembly, that is, on one side of the longitudinal air duct. A flow guide structure 24 (such as Figure 3 The side of the guide structure facing the air supply area is a smooth curved surface, which can effectively guide the airflow direction. A drain port 25 connected to the water tank is provided at the bottom of the longitudinal air duct, and a drain trough 26 connected to the water tank is also provided at the bottom of the air guide cover.

[0032] The outside of the air purification component is provided with an air inlet filter serving as the main air inlet of the equipment. The inside of the air inlet filter is provided with a first activated carbon layer and a HEPA (high-efficiency air filter) in sequence. The air inlet filter, the first activated carbon layer and the HEPA constitute the air purification component.

[0033] The water tank is also provided with a concealed water purification component A (such as Figure 3 or Figure 4 As shown), Figure 2 As shown, the water purification component includes a medical stone layer 31, a silver ion cotton layer 32, a second activated carbon layer 33 and a filter material cover 34 arranged in sequence from bottom to top; the water pipe includes a water pump and a water supply pipe, the water inlet end of the water pump is connected to the water purification component, the water outlet end of the water pump is connected to the water pump, the water inlet end of the water supply pipe is connected to the water pump outlet, and the water outlet end of the water supply pipe is connected to the water inlet of the stepped atomization box.

[0034] The humidification and purification method of the humidification and purification integrated machine with the stepped atomization device in this embodiment is specifically as follows: in the ultrasonic atomization device, in the stepped atomization box, after water enters the highest atomization unit from the water inlet, as the water level in the highest atomization unit rises, the water overflows to the atomization unit of the next level after it is full, and then overflows step by step until the lowest atomization unit is also full of water, and the excess water is discharged from the overflow tank; the ultrasonic atomization sheets in the atomization units at each level atomize the water in the atomization unit to form an inclined upward water mist column (such as Figure 4 At the same time, the fan assembly sends the purified airflow to the air supply area, and the airflow is also transported in an upward tilt (as shown in the dotted line in the figure). Figure 4 As shown in the direction of the arrow in the figure), on the one hand, the airflow carries the water mist in the water mist column and sends it to the main air outlet of the equipment during the rising process, forming humidified and purified air (realizing large fog output, so that the fog is effectively stirred in the space, making its humidity more balanced).

10. The humidification and purification method of the humidification and purification integrated machine with a stepped atomization device according to any one of claims 1 to 9, characterized in that: In the ultrasonic atomization device, in the stepped atomization box, after water enters the highest atomization unit from the water inlet, as the water level in the highest atomization unit rises, the water overflows to the atomization unit of the next level after it is full, and then overflows step by step until the lowest atomization unit is also full of water, and the excess water is discharged from the overflow trough; the ultrasonic atomization sheets in the atomization units at each level atomize the water in the atomization unit to form an upward inclined water mist column. At the same time, the fan assembly sends the purified airflow into the air supply area, and the airflow is also transported in an upward inclined manner. On the one hand, the water mist in the water mist column is carried to the main air outlet of the equipment during the rising process of the airflow to form humidified and purified air. On the other hand, the airflow also prompts the water mist column in each atomization unit to hit the atomization unit of the upper level, thereby forming a water reflux effect in the stepped atomization box.
