Description

Technical Field

[0001] The present invention relates to the technical field of air purification and humidification, and particularly to an air purification and humidification integrated machine. Background Art

[0002] An air purifier filters the air through a filter structure inside the air purifier after introducing fresh air through a fan and other structures, and then discharges the air again to purify the indoor air.

[0003] An air humidifier extracts water to the atomization structure inside the humidifier, forms mist with the water flow through the atomization structure, and discharges the mist into the room to humidify the indoor air.

[0004] In some related technologies, air purification and air humidification are achieved by using different devices. For example, if you want cleaner air, you need a separate air purifier. Another example is that if you want a certain humidity in the air, you need another humidifier.

Unless otherwise specified, the meaning of "a plurality" is two or more.

[0044] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0045] Refer to Figures 1-10 , an air purification and humidification integrated machine, including a body 10, a purification and humidification component 30 and an air inlet component. A wind cavity 11, a purification and humidification cavity, an air outlet 13 and an air inlet 14 are provided on the body 10. The air outlet 13 is communicated with the wind cavity 11, the air outlet cavity 11 can be communicated with the purification and humidification cavity, and the air inlet 14 is communicated with the purification and humidification cavity.

[0046] Specifically, the purification and humidification component 30 includes an air filter element 31 and an air humidification element. The air filter element 31 and the air humidification element are both installed in the purification and humidification cavity, and the air filter element 31 and the air humidification element are arranged at intervals in the purification and humidification cavity. The air filter element 31 is arranged outside the air humidification element, and a humidification space 12 is formed inside the air humidification element. The wind cavity 11 is communicated with the humidification space 12, and the above air inlet 14 can be communicated with the purification and humidification cavity and conducted to the outside of the air filter element 31.

[0047] The above air inlet component is arranged in the wind cavity 11. When the air inlet component is started, it can guide the air flow to be introduced through the air inlet 14 and flow through the air filter element 31 and the air humidification element to the humidification space 12 in sequence.

[0048] On the basis of the above structure, when using the air purification and humidification integrated machine of the present invention, the above wind cavity 11 is located above the purification and humidification cavity. The air inlet component is started, and at the same time, the air humidification element can perform humidification treatment. The air inlet component arranged in the wind cavity 11 guides the air flow to enter the air inlet 14 from the air outside the body 10. Since the air filter element 31 is located in the purification and humidification cavity and corresponds to the air inlet 14, the introduced external air can be filtered by the air filter element 31, so that the purified air then flows to the air humidification element. The purified air is humidified by the mist generated by the air humidification element and then enters the humidification space 12. The humidified and purified air in the humidification space 12 can be further guided by the air inlet component into the wind cavity 11 and then discharged through the air outlet 13 communicated with the wind cavity 11 to purify and humidify the indoor air and improve the indoor air quality.

[0049] Of course, in other embodiments, when purifying indoor air, the air humidifying member may not be activated. The air inlet assembly operates to guide external gas to flow through the air inlet 14 into the purification and humidification chamber. The external gas can then be purified by the air filter member 31. In this way, the purified air can enter the humidification space 12. Since the air humidifying member may not be enabled at this time, this air purification and humidification integrated machine can be directly used as an air purifier.

[0050] Therefore, in this embodiment, by arranging both the air filter member 31 and the air humidifying member in the purification and humidification chamber, when performing air humidification treatment indoors, the air inlet assembly in the air chamber 11 can guide the air flow to enter the purification and humidification chamber through the air inlet 14, filter the air flow and then perform humidification treatment before entering the humidification space 12, and discharge it through the air outlet 13, so that the air can be purified and humidified. When the air needs to be purified alone, the air humidifying member is not activated, so that this air purification and humidification integrated machine can independently perform the air purification action, and thus can be used for two purposes.

[0051] Whether it is air humidification or air purification, the air flow passing through the air humidifying member each time is the purified air flow. Therefore, the impurities remaining on the air humidifying member can be reduced, and situations such as the air humidifying member emitting an odor can be avoided, improving the service life of the air humidifying member.

[0052] Of course, in some embodiments, the above air filter member 31 can directly adopt the air filter member 31 in related technologies. For example, the air filter member 31 can include a primary filter, a HEPA filter, and an activated carbon substrate filter. The primary filter, the HEPA filter, and the activated carbon substrate filter are all porous honeycomb structures, so that air can be purified through this air filter member 31.

[0053] The air humidifying member can directly adopt the air humidification structure in related technologies. For example, the air humidifying member can include a humidifying mesh, and the humidifying mesh is a porous honeycomb structure, which increases the contact area between water and air, and increases the air humidity through the principle of natural evaporation. Thus, air can be humidified through this air humidifying member.

[0054] Of course, the above air humidifying member can be an atomization structure in related technologies, such as an ultrasonic atomization structure, which uses the high-frequency oscillation generated by an ultrasonic transducer to atomize water into ultra-fine particles. Another example is a hot fog atomization structure, which uses a heating element to heat a liquid to the boiling point to generate water vapor and release it into the air for humidification. The specific structure of the air humidifying member can be selected and set according to actual needs.

[0055] As an alternative embodiment, see Figure 6 and Figure 7, the above air humidifying member may include a filter mesh frame 32 and a humidifying filter mesh 33. The humidifying filter mesh 33 is disposed around the filter mesh frame 32, and a humidifying space 12 is formed inside the filter mesh frame 32. Based on this structure, the filter mesh frame 32 is installed in the purification and humidification cavity and serves as the installation basis for the humidifying filter mesh 33, so that the humidifying filter mesh 33 can be disposed around the filter mesh frame 32. When air humidification is performed, water needs to be added to the humidifying filter mesh 33. In this way, when the air inlet assembly is started to guide the air flow to pass through the air filtering member 31 for filtering, the purified air flow passes through the wet humidifying filter mesh 33, forms an atomized air flow with moisture, enters the humidifying space 12, and then enters the air cavity 11 and is discharged through the air outlet 13.

[0056] It should be noted that if the unfiltered air flow is directly guided to the humidifying filter mesh 33, impurities, dust, etc. that have not been purified will remain in the humidifying rate. In this way, the humidifying filter mesh 33 will stink and breed bacteria during long-term use, affecting the air quality after humidification. Therefore, in this embodiment, the air flow flowing to the humidifying filter mesh 33 is the air flow purified by the air filtering member 31, so as to reduce the situation of the humidifying filter mesh 33 stinking and improve the air humidification quality.

[0057] As an alternative embodiment, referring to Figure 8 , a humidifying tank 322 may be provided at the top of the filter mesh frame 32. A plurality of water passing holes 323 are provided in the humidifying tank 322. The plurality of water passing holes 323 are distributed in the circumferential direction of the filter mesh frame 32 and guide the water flow in the humidifying tank 322 to the humidifying filter mesh 33. With such a setting, since the humidifying filter mesh 33 is disposed outside the filter mesh frame 32, when humidification is performed, the water flow in the humidifying tank 322 at the top can flow to the humidifying filter mesh 33 through the plurality of water passing holes 323 in the axial direction. In this way, the water flow on the humidifying filter mesh 33 is evenly distributed. When the air inlet assembly guides the gas to flow, the gas can enter through the humidifying filter mesh 33 distributed in the circumferential direction, so that the air flow can fully contact the humidifying filter mesh 33 and the humidifying effect is uniform.

[0058] Of course, since the plurality of water passing holes 323 guide the water flow in the humidifying tank 322 to the humidifying filter mesh 33 in the circumferential direction, it helps to form a water curtain. When gas flows to the humidifying filter mesh 33, it is easier to form mist for humidification, so the humidifying efficiency is higher.

[0059] In the related art, in addition to directly adding water flow to the humidifying tank 322, the humidifying tank 322 can also be connected to an external water pipe, or the following embodiment can be selected, that is, a water tank 15 and a water pump assembly 40 are provided on the machine body 10 to guide the water flow to the humidifying tank 322 for humidification treatment.

[0060] In this embodiment, a water tank 15 can be provided at the bottom end of the body 10, and a water pump assembly 40 is correspondingly provided in the water tank 15. The water pump assembly 40 is used to guide the water flow in the water tank 15 to the humidifying tank 322; a water return port 121 is provided at the bottom end of the purification and humidification chamber, and the water return port 121 is conducted to the bottom end of the humidifying space 12, and the water return port 121 is conducted to the water tank 15.

[0061] It should be noted that water can be stored by setting the water tank 15. The water tank 15 and the main body structure of the all-in-one machine can be connected by clamping or sliding. The user can add water by pulling the water tank 15.

[0062] Specifically, when using the air humidifying component, by starting the water pump assembly 40, the water pump assembly 40 can guide the water in the water tank 15 to the humidifying tank 322. After the water flow flows to the humidifying tank 322, it then flows through the plurality of water passing holes 323 of the humidifying tank 322 to the humidifying filter screen 33. The water flow on the humidifying filter screen 33 comes into full contact with the air flow guided by the air inlet assembly to humidify the air.

[0063] Since the water flow flowing on the humidifying filter screen 33 may not completely generate mist, or there may be mist in the humidifying space 12 that is not discharged in time and water droplets are generated inside, the excess water flow remaining in the humidifying space 12 or on the humidifying filter screen 33 can flow to the water return port 121 of the humidifying space 12. The water return port 121 guides the water flow into the water tank 15 for recycling, which enables the recycling of water and saves water resources.

[0064] Furthermore, a water inlet filter element 141 is provided in the water tank 15. The water inlet filter element 141 is used to form a filter chamber in the water tank 15. The water pump assembly 40 is installed in the filter chamber and is used to guide the water flow in the filter chamber to the humidifying tank 322.

[0065] In some embodiments, the water pump assembly 40 includes a water pump 41 and a water guide pipe 41. The water inlet end of the water pump 41 is conducted to the filter chamber, the water outlet end of the water pump 41 is conducted to the water guide pipe 41, and the water guide pipe 41 is conducted to the humidifying tank 322. In this way, when the water pump 41 is started, the filtered water in the filter chamber can be guided into the water guide pipe 41 and led to the humidifying tank 322 through the water guide pipe 41.

[0066] In this way, when performing humidification treatment, the water pump 41 is started. The water pump 41 works to guide the water flow in the water tank 15. The water flow can flow to the water inlet filter element 141, enter the filter chamber after being filtered by the water inlet filter element 141, and then be guided to the water guide pipe 41 by the water pump 41. In this way, the water flow led out from the water guide pipe 41 to the humidifying tank 322 is the filtered water flow in the filter chamber. When flowing to the humidifying filter screen 33, since the water flow has been filtered and the air flow has also been filtered, the generated mist is purified mist, and the air quality after humidification and purification is better.

[0067] In addition, since the water flow to the humidifying filter screen 33 is filtered, the impurities in the water flow are reduced from flowing to the humidifying filter screen 33, thereby reducing the situation of the humidifying filter screen 33 emitting an odor due to the retention of impurities and the like. At the same time, the air flow introduced through the humidifying filter screen 33 is also filtered, and the water flowing back from the humidifying filter screen 33 is also the water flow with reduced air impurities mixed in. Therefore, it is also possible to reduce the impurities brought back by the return water into the water tank 15 and reduce the scale formation in the water tank 15.

[0068] As an alternative implementation, refer to Figure 6 、 Figure 7 and Figure 8 . In order to facilitate the assembly of the humidifying filter screen 33 and the filter mesh frame 32, a first positioning frame 16 may be provided at the top of the filter mesh frame 32, and a second positioning frame 17 may be provided at the bottom wall of the purification and humidification chamber. Both the first positioning frame 16 and the second positioning frame 17 can extend in the circumferential direction of the filter mesh frame 32. A first positioning groove 161 is provided on the first positioning frame 16, and a second positioning groove 171 is provided on the second positioning frame 17. In this way, when assembling the humidifying filter screen 33, the top end of the humidifying filter screen 33 is installed in the first positioning groove 161, and the bottom end of the humidifying filter screen 33 is installed in the second positioning groove 171. In the related art, the filter mesh frame 32 can be selected as a bracket formed by a mesh structure, and the top end and the bottom end of the humidifying filter screen 33 are annularly installed with the first positioning groove 161 and the second positioning groove 171, so as to fit on the mesh structure of the filter mesh frame 32. When replacing the humidifying filter screen 33, the top end and the bottom end of the humidifying filter screen 33 can be detached from the corresponding first positioning frame 16 and second positioning frame 17.

[0069] It should be noted that since the humidifying filter screen 33 is attached and supported by the mesh structure of the filter mesh frame 32, it does not affect the flow of the mist formed on the humidifying filter screen 33 into the humidifying space 12 surrounded by the filter mesh frame 32. And on the basis of this structure, a humidifying groove 322 can be provided on the first positioning frame 16, and a water guiding channel 321 can be provided on the filter mesh frame 32. The water guiding channel 321 is communicated with the water guiding pipe 41 of the water pump assembly 40. After the water pump 41 guides the water flow in the water tank 15 into the water guiding pipe 41, it is then guided into the humidifying groove 322 through the water guiding channel 321 to humidify the humidifying filter screen 33.

[0070] Of course, the first positioning frame 16 and the second positioning frame 17 can be assembled to the purification and humidification chamber of the machine body 10 through structures such as screws and buckles, which is convenient for later cleaning.

[0071] As an optional embodiment, in order to facilitate the positioning and assembly of the air filter 31, a third positioning frame 18 is provided at the top of the purification and humidification chamber, and the third positioning frame 18 is provided with a third positioning groove 181; the second positioning frame 17 is also provided with a fourth positioning groove 191, and the fourth positioning groove 191 is provided on the outer side of the second positioning groove 171, and the top end of the air filter 31 is installed in the third positioning groove 181; the bottom end of the air filter 31 is provided in the fourth positioning groove 191.

[0072] It should be noted that since the air filter element 31 and the air humidifier in this embodiment are respectively formed by structures such as filter nets, filter cores or filter membranes in the relevant technology, in order to form a certain filtering support strength after assembly, the first positioning frame 16, the second positioning frame 17, the third positioning frame 18, and the fourth positioning frame 19 are used to unfold the corresponding filter nets, filter cores or filter membranes and other structures up and down, so that the effective filtering and humidification surface formed is larger and the assembly structure is stable.

[0073] See also Figure 7 In some embodiments, the second positioning frame 17 and the fourth positioning frame 19 are made of an integrally formed positioning plate structure, and the second positioning frame 17 and the fourth positioning frame 19 are formed by processing positioning rings, positioning sheets and other structures on the positioning plate structure to form the inner and outer distributed second positioning frame 17 and the fourth positioning frame 19, and the corresponding positioning groove structure is formed by the positioning sheets and positioning rings.

[0074] As an optional embodiment, the air outlet 13 is provided with an air outlet assembly, which includes an air outlet main structure 50, an end of the air outlet main structure 50 is provided with a water inlet, the water inlet is connected to a water guide, and the water guide is connected to the water tank 15; an air outlet is provided on the circumferential side of the water inlet, and the water guide and the water outlet are staggered in the circumferential direction of the air outlet main structure 50;

[0075] The air inlet assembly includes a fan structure 20, which is arranged in the inner cavity of the air outlet main structure 50. An air outlet duct 111 is provided between the air outlet main structure 50 and the fan structure 20. The top end of the air outlet duct 111 is connected to the air outlet part, and the bottom end of the air outlet duct 111 is connected to the humidification space 12.

[0076] The air outlet component in the present invention is provided with a water inlet part, the water inlet part is communicated with a water guiding part, and the air outlet part is arranged on the periphery of the water inlet part. Therefore, when adding water, the user can avoid the air outlet part to add water at the position of the air outlet component, and the fan structure 20 does not need to stop during the water adding operation; the air outlet part is arranged on the periphery of the water inlet part, and the water guiding part and the air outlet part are staggered in the circumferential direction of the air outlet main structure 50. There is an air outlet duct 111 between the air outlet main structure 50 and the fan structure 20. When purifying and humidifying the air, the fan mechanism starts, which can form a negative pressure in the air cavity 11 to guide the external air flow to enter the purification and humidification cavity through the air inlet 14. After entering, the air flow introduced through the air inlet 14 is first filtered by the air filter element 31. After filtration, the air flow reaches the position of the air humidifying element. Under the guidance of the fan structure 20, the air flow passes through the air humidifying element and mixes with the mist generated at the air humidifying element, and then enters the humidification space 12. In this way, the purified and humidified air flow in the humidification space 12 can enter the air cavity 11 and flow through the air cavity 11 to the air outlet duct 111, and is led to the air outlet part of the air outlet main structure 50 for outlet.

[0077] It should be noted that since the air outlet part is arranged on the periphery of the water inlet part, there is an air outlet duct 111 between the air outlet main structure 50 and the fan structure 20, and an air inlet part is arranged on the periphery of the fan structure 20. When the fan structure 20 works, the air flow enters the air cavity 11 and is then led to the multiple air outlet parts on the periphery of the air outlet main structure through the air outlet duct 111 for outlet, which is likely to form a rotating air flow and is not easy to form a direct air flow. Compared with the direct air flow, the rotating air flow is more comfortable and gentle. For the application scenarios that need to humidify with the air flow, the rotating air flow can reduce the situation of too high local humidity.

[0078] Since the air outlet part is arranged on the periphery of the water inlet part, that is, the water inlet part is arranged in the central area of the air outlet part. Since the wind force in the central area of the air outlet part is generally weak to form a low-pressure area, compared with arranging the water inlet part and the air outlet part side by side, arranging the air outlet part on the periphery of the water inlet part can utilize the central area of the air outlet part to reduce the influence of the water inlet part on the air outlet of the air outlet part.

[0079] Since the water guiding part is arranged in the air outlet duct 111, when the user adds water at the position of the air outlet component, the water is introduced into the water storage part of the air purification and humidification machine described below through the water inlet part and the water guiding part. The water does not pass through the fan structure 20, and there is no interference between the fan structure 20 and the water guiding part. Therefore, the fan structure 20 does not need to stop during the water adding operation, which is convenient for the user to operate.

[0080] The influence of the water guide part on the air outlet can be reduced by controlling the set shape, set size, and set quantity of the water guide part. For example, a linear tubular water guide part is set, the outer diameter of the water guide part is 1 cm - 2 cm, and the outer diameter of the air outlet main body structure 5010 is 10 cm - 20 cm.

[0081] Of course, in some embodiments, since a water inlet part is provided at the top of the air outlet main body structure 50, when performing the water addition operation, water can be directly added to the water inlet part at the top of the machine body 10, and the water guide part of the water inlet part guides the water flow into the water tank 15 of the machine body 10 for the water addition operation. At the same time, it is also possible to directly take out the water tank 15 of the machine body 10 and directly perform the water addition operation in the water tank 15.

[0082] As an alternative embodiment, refer to Figure 4 , Figure 9 and Figure 10 , a water inlet groove 51 is provided at the end of the air outlet main body structure 50; the water inlet groove 51 is formed as a water inlet part;

[0083] A water guide outlet 511 is provided on the groove wall of the water inlet groove 51. The water inlet groove 51 is connected with a down water pipe 512 through the water guide outlet 511. The down water pipe 512 passes through the air duct and penetrates to the outside of the air outlet main body structure 50. The down water pipe 512 forms a water guide part.

[0084] In the embodiment of the present invention, a water inlet groove 51 is provided at the end of the air outlet main body structure 50, and the water inlet groove 51 is formed as a water inlet part.

[0085] When the end of the air outlet main body structure 50 is arranged upward or sideways, the user can directly perform the water addition operation on the water inlet groove 51 from the end of the air outlet main body structure 50.

[0086] In the embodiment of the present invention, a water guide outlet 511 is provided on the groove wall of the water inlet groove 51. The water inlet groove 51 is connected with a down water pipe 512 through the water guide outlet 511. The down water pipe 512 passes through the air duct and penetrates to the outside of the air outlet main body structure 50. The down water pipe 512 forms a water guide part.

[0087] When the end of the air outlet main body structure 50 is arranged upward, the top of the water inlet groove 51 has an opening for water addition. The water guide outlet 511 can be arranged on the side wall or the bottom wall of the water inlet groove 51. In order to avoid the influence of the water guide outlet 511 on the arrangement of the fan structure 20, the water guide outlet 511 is arranged on the side wall of the water inlet groove 51; when the water guide outlet 511 is arranged on the side wall of the water inlet groove 51, in order to facilitate drainage and avoid water accumulation in the water inlet groove 51, the water guide outlet 511 is arranged close to the bottom wall of the water inlet groove 51.

[0088] As an alternative embodiment, refer to Figure 9and Figure 10 The air outlet main structure 50 includes an air outlet grille, which is arranged around the circumference of the water inlet part. Specifically, the air outlet grille includes at least two air guide vanes 53, and two adjacent air guide vanes 53 enclose an air outlet hole 52, and the air outlet hole 52 forms the air outlet part;

[0089] There is an included angle a between the extending direction of the air guide vane 53 and the axial direction of the air outlet main structure 50.

[0090] In the embodiment of the present invention, the air outlet main structure 50 includes an air outlet grille, which is arranged around the circumference of the water inlet part. The air outlet grille includes at least two air guide vanes 53, and two adjacent air guide vanes 53 enclose an air outlet hole 52, and the air outlet hole 52 forms the air outlet part; there is an included angle a between the extending direction of the air guide vane 53 and the axial direction of the air outlet main structure 50.

[0091] Specifically, the air outlet grille is a ring structure, and the air outlet main structure 50 further includes a main body, which is a sleeve structure with a hollow interior. For the convenience of assembly, the main body is formed by connecting two split parts; the air outlet grille and the main body can be connected and fixed by means of tight fit, snap connection, etc.; the water inlet groove 51 can be formed by concave molding in the main body, or the water inlet groove 51 can be a sleeve structure, and the water inlet groove 51 of the sleeve structure and the main body can be connected and fixed by means of tight fit, snap connection, etc.

[0092] It can be understood that the air outlet part formed between two adjacent air guide vanes 53 is a through-hole structure, and multiple air guide vanes 53 are arranged at intervals in the circumferential direction around the water inlet groove 51 to form a multi-hole air outlet structure.

[0093] For the convenience of air guiding, multiple air guide vanes 53 are arranged at intervals in the circumferential direction around the water inlet groove 51. Since there is an included angle a between the extending direction of the air guide vane 53 and the axial direction of the air outlet main structure 50, and the value range of a is: 30°≤a≤60°, so that the air flow can form a rotating air flow after passing through the air inlet part, the air duct and the air outlet part, thereby increasing the air outlet speed and air outlet volume of the air outlet part and reducing the air outlet noise.
