Description

Air treatment device

Technical Field

The present utility model relates to an air treatment device.

Background

In order to improve the air quality of the enclosed indoor environment, various air treatment devices are currently on the market. For example, a humidifying device is known. The humidifying device may include, for example, an outer housing, a humidifying module housed in the outer housing, and the like. On the one hand, since the air flow paths are arranged inside the outer case, air leakage is liable to occur between the air flow paths. On the other hand, the wall portion of the outer case is spliced with the wall portion, so that the outer case itself has a problem of air leakage. Such air leakage or air leakage can significantly affect the thermal insulation effect of the air treatment device and even risk condensation.

In order to improve the sealing performance of a humidifying device, it is known to provide an insulation assembly in the outer housing of the humidifying device, the insulation assembly comprising a plurality of insulation elements. The heat preservation pieces are independent of each other, and can respectively conduct heat preservation treatment on the upper top plate and the lower bottom plate of the outer shell.

However, since the heat insulating parts are separately arranged, the sealing effect is limited, and a certain possibility of air leakage exists in the humidifying device. For this reason, it is known that a special sealing treatment is required for the connection between the individual insulating elements. In addition, the assembly of multiple insulation elements is time consuming and labor intensive, such as requiring alignment with each other or installation with special tools, etc.

Disclosure of Invention

In order to improve the sealing performance of a housing of an air treatment device, the utility model relates to an air treatment device, which comprises an outer housing, wherein the outer housing encloses an accommodating space, the air treatment device also comprises an inner housing, and the inner housing comprises a first inner housing and a second inner housing; the first inner shell is integrally formed into a frame body with an opening at the bottom, and an air inlet and an air outlet are arranged on a pair of side walls of the frame body; the second inner shell covers the opening at the bottom of the first inner shell; the outer side surfaces of the first inner shell and the second inner shell are contacted with the inner side surface of the outer shell; on the path from the air inlet to the air outlet, a temperature adjusting element and a humidifying element are sequentially arranged on the inner shell.

With the aid of the air treatment device, as the first inner shell integrally forms the frame body, compared with the scheme that the shell is assembled by different shell parts, gaps caused by assembly (e.g. splicing) can be reduced, the tightness of the shell is improved, air leakage is reduced, and therefore the heat preservation effect of the air treatment device is improved and the risk of condensation is reduced to the minimum.

Preferably, the inner sidewall edge of the first inner housing is formed with a stepped portion, and the second inner housing is embedded in the stepped portion.

By means of the step, the second inner housing can be easily and operatively mounted in the opening of the bottom of the first inner housing. By embedding the second inner housing into the stepped portion, the sealing performance of the inner housing can be further improved. The design of the step is also simple and can be integrally formed at the time of manufacturing the first inner case.

Advantageously, the side wall on which at least one of the air inlet and the air outlet is located has a detection unit mounting portion.

The detection unit mounting portion may be used to monitor an air treatment condition of the air treatment device, such as a humidification condition, a tempering condition, or other physical parameter. The detection unit mounting part is arranged on the side wall with the air inlet and/or the air outlet, so that the mounting structure is very simple, and the processing of the inner shell is simplified.

Optionally, an opening is provided at the top of the first inner casing, the opening at the top forms a humidifying element mounting portion, and the humidifying element is embedded in the opening at the top.

The opening is arranged at the top of the first inner shell to form the humidifying element installation part, so that the humidifying element can be conveniently replaced and maintained. By embedding the humidifying element in the opening, the sealability of the housing can be improved while the installation is facilitated.

In particular, the humidifying element is movable along the humidifying element mounting portion in the length direction.

By this movement, maintenance, installation and replacement of the humidifying element are made easier. In addition, moving the humidifying element along the humidifying element mounting portion also stabilizes the overall movement.

In particular, the thickness of the humidifying element mounting portion is greater than the thickness of the top wall elsewhere in the housing.

Thus, the contact area between the humidifying element mounting portion or the opening at the top of the first inner casing and the humidifying element can be increased, so that the mounting is stable, and the strength of the opening is kept high.

More preferably, one end of the humidifying element mounting portion has a stopper.

Since the humidifying element can be mounted in place against the stopper, it is possible to further improve the air flow tightness of the inner casing by reducing the undesired spacing.

Further, the top of the first inner case is provided with an inner recess in which the humidifying element is disposed.

Since the non-open structure with the concave top can be utilized to receive the humidifying element, the integrity of the housing and the sealing performance can be further improved (the concave portion can also form the foregoing humidifying element mounting portion).

More advantageously, a temperature adjusting element mounting portion is provided on at least one of the first inner housing and the second inner housing, the temperature adjusting element mounting portion being of a slope structure.

The temperature adjusting element mounting part is arranged on the inner shell, so that the temperature adjusting element can be conveniently mounted. The temperature adjusting element mounting part is designed into a slope structure, so that the drainage of the temperature adjusting element can be facilitated.

Optionally, one side wall of the first inner housing is provided with an access opening.

The access opening may be used to facilitate operation or viewing by service personnel without opening the air treatment device, and the provision of the access opening on one side wall of the first inner housing does not obstruct the view of the personnel due to the installation of certain components.

It is particularly advantageous if the first inner housing is integrally formed from a soft material.

By means of soft materials, the heat insulation performance of the inner shell can be improved, heat conduction is reduced, and meanwhile, the part mounted on the first inner shell is matched with the first inner shell more tightly by means of deformation possibly existing, so that the sealing performance is further improved.

It is also advantageous if the second inner housing is integrally formed from a soft material. Therefore, the second inner shell can be jointed with the first inner shell more in a fitting way, so that the sealing performance of the inner shell is further improved, the heat insulation performance of the inner shell is also improved, and the heat conduction is reduced.

For example, the soft material for the first inner case and/or the second inner case is a foaming material or a soft resin.

The foaming material or soft resin is light and has good heat preservation performance. In addition, the material is easy to process, for example, the material is easy to integrally mold.

Preferably, the outer sides of the first and second inner housings match the shape of the inner sides of the outer housing.

By matching the shape of the outer side of the inner housing with the shape of the inner side of the outer housing, a compact arrangement can be achieved by fully utilizing the space structure.

In the present utility model, the expressions "first", "second", etc. are used merely to distinguish different components, but do not indicate their priority or importance.

Furthermore, the terms "inner," inner, "and" outer, "" outer, "are generally absolute positions, i.e.," inner "is within" outer, "and" outer "is outside" unless otherwise indicated.

Although an air treatment device is described in the present utility model, it should be understood that it is understood to be any device that treats air. Such treatments include, but are not limited to, filtration, tempering (including heating, cooling, or a combination thereof), conditioning humidity (e.g., humidification), flavoring, and the like.

(integral Structure of air treatment device)

According to the present utility model, the air treatment device 100 includes an outer housing. In general, an outer shell refers to a separate shell component, which is considered an outer shell even if its walls or any other portion are constructed as a multi-layer comprising a hollow structure. The outer housing may be generally composed of a resin, a metal material, or a polymer, and encloses an accommodation space forming an interior. Although not shown in the drawings, the outer case is preferably rectangular parallelepiped. The air treatment device 100 may be mounted in a desired mounting location by its outer housing, for example, hung from a vertical wall in a room or hung from a ceiling in a room.

In the above-described accommodation space, the air treatment device 100 includes an inner case. In various embodiments of the present utility model, the inner housing is in contact with the outer housing. Specifically, the outer side surface of the inner shell is in contact with the inner side surface of the outer shell, and no gap is left between the inner shell and the outer shell at the contact position. The term "contacting" herein includes partial contact, e.g. a portion of the outer side of the inner housing being in contact with the inner side of the outer housing, as well as complete contact, e.g. the entire outer side of the inner housing being in contact with the inner side of the outer housing. Preferably, the outer side of the wall of the inner housing is at least in contact with, in particular in close contact with, the inner side of the wall of the outer housing.

As exemplarily shown in fig. 1-6, the inner housing is generally rectangular parallelepiped-shaped. In particular, the inside of the inner case of the present utility model forms a gas flow path of the air treatment device 100. Specifically, an air inlet 182 and an air outlet 184 of the air treatment device 100 are provided in the inner case. Herein, the term "air intake" refers to an inlet for introducing air into the air treatment device 100, and "air outlet" refers to an outlet for discharging treated air out of the air treatment device 100. In the present utility model, the air inlet 182 and the air outlet 184 include at least an opening portion provided on the inner case, but may include an associated air outlet member provided on the opening portion.

Advantageously, the side wall of at least one of the inlet 182 and outlet 184 has a detection unit mounting 186 for monitoring the air handling condition of the air handling unit 100, such as a humidification condition, a tempering condition, or other physical parameter. As shown in fig. 1, the detection unit mounting portion 186 is disposed in adjacent communication with the air outlet 184, i.e., the detection unit mounting portion 186 is also formed together on the side wall of the air outlet 184.

In the gas flow path from the inlet 182 to the outlet 184, the air treatment device 100 further comprises a temperature regulating element 140, which temperature regulating element 140 is arranged on the inner housing for regulating the temperature of the gas flow flowing from the inlet 182 to the outlet 184. Preferably, the temperature adjusting element 140 may be a heat exchanger (the heat exchanger may include a heating medium circuit and a cooling medium circuit, for example) or an electric heater, for heating the air entering the air treatment device 100 to a desired temperature (for example, a temperature suitable for a subsequent humidification process).

Downstream of the temperature control element 140, a humidifying element 130 is also provided on the inner housing for humidifying the air flowing through. The term "downstream" is used herein with respect to the gas flow path, i.e., downstream elements are closer to the outlet 184 than upstream elements. In other words, the temperature adjusting element 140 and the humidifying element 130 may be sequentially provided on the inner case on a path from the air inlet 182 to the air outlet 184. It is noted that in the present utility model, the air treatment device 100 may further include other functional elements to perform other treatments of the air in addition to temperature adjustment and humidification.

According to the present utility model, a top plate 190 may be further provided on the inner case, particularly at the top, for further covering the seam provided on the inner case to improve sealing performance, and the top plate 190 may also facilitate connection or installation between the inner case and the outer case. Preferably, the top plate 190 covers the humidifying element mounting portion 150 formed by the first inner case 110.

(Structure of inner housing)

In the present utility model, the inner housing is a separate housing from the outer housing. The inner shell may comprise one or more layers. The inner housing includes a first inner housing 110 and a second inner housing. As already mentioned above, the outer side of the inner housing is in (at least partly) contact with the inner side of the outer housing, preferably the entire outer side of the inner housing is in contact with the inner side of the outer housing. More preferably, the entire outer side of the inner housing is in contact with the entire inner side of the outer housing.

In particular, the outer side of the inner housing may match the shape and size of the inner side of the outer housing. In this case, there is substantially no significant gap between the inner and outer shells, which are in a close contact. For example, in the case of a rectangular parallelepiped outer shell, the inner shell may also be rectangular parallelepiped and be adapted in shape and size at each of its faces. Notably, the gap due to minor dimensional errors or due to components or devices mounted on the inner housing is not within the scope of a "significant gap".

The inner case according to the present utility model includes a first inner case 110 and a second inner case 120. The first inner housing 110 is integrally formed as a frame having an opening 118 at the bottom, as best shown in fig. 1 and 5. Herein, the term "integrally formed" means that the first inner housing 110 is one piece or unitary, rather than being assembled from multiple parts as in the prior art. The integrally formed frame may significantly reduce gaps due to assembly (e.g., splicing) as compared to frames assembled from different components, thereby improving the sealing performance of the air treatment device 100 and reducing air leakage. Furthermore, it will be appreciated that although described as a "frame," this does not mean that the first inner housing 110 is wire-frame shaped, but rather that each side (e.g., top, side) includes at least a continuously extending section, such as a continuously extending plate portion, although it is possible to provide a plurality of openings spaced apart from one another on these sections.

The first inner case 110 may be formed of, for example, a soft material, preferably a foaming material, and other resin-based soft materials are also suitable. Suitable foams such as polystyrene (EPS), suitable soft resin materials include ABS, PP, HIPS, POM and the like. Preferably, the second inner case 120, which will be described in detail below, may also be made of a soft material. In the present utility model, the term "soft material" is a concept as opposed to rigid or stiff materials, which are generally lighter in weight and have some thermal insulation (not as readily thermally conductive as metals). Such soft materials may deform somewhat upon application of pressure (e.g., an insert member), which also helps create a tight fit with the member that it receives or engages, thereby improving sealing performance.

The aforementioned air inlet 182 and air outlet 184 are provided on a pair of side walls of the first inner case 110, particularly on side walls opposite to each other, as exemplarily shown in fig. 1 to 3. The shape and size of the air inlet 182 and the air outlet 184 may be designed according to the amount of air flow required by the air treatment device 100, and will not be described herein. Although described above as having an opening 118 at the bottom, the first inner housing 110 may also be provided with additional openings at other locations, for example for mounting various components. But only the aforementioned opening at the bottom is for cooperation with the second inner housing 120.

More specifically, the second inner housing 120 covers the opening 118 of the bottom of the first inner housing 110. In the present utility model, the second inner housing 120 covers the opening 118 to such an extent that it does not substantially cause air leakage of the air treatment device 100. The term "cover" is intended herein to cover the bottom opening 118, but the manner of how it is covered is not particularly limited (including but not limited to, snap-fit, splice, adhesive, etc.). Such a covering may further enhance the sealing performance of the air treatment device 100. In some embodiments, the second inner housing 120 may snap directly onto the first inner housing 110 to cover the opening 118.

Preferably, the opening 118 of the bottom of the first inner housing 110 occupies substantially the entire bottom thereof, i.e., the opening 118 has a size about equal to or slightly smaller than the bottom of the first inner housing 110. In this case, the size of the second inner case 120 may be approximately equal to the size of the opening 118 of the bottom of the first inner case 110. It will be appreciated that the second inner housing 120 covering the opening 118 of the bottom of the first inner housing 110 does not mean that the second inner housing 120 must constitute the outermost boundary of the first inner housing 110, particularly the rectangular parallelepiped-shaped first inner housing 110, e.g., the second inner housing 120 may be recessed inwardly (i.e., toward the center of the frame constituted by the first inner housing 110) in the opening 118 of the bottom by a distance relative to the bottom outermost boundary constituted by the side walls of the first inner housing 110. Of course, it is preferable that the second inner case 120 constitutes the outermost boundary of the bottom of the rectangular parallelepiped-shaped first inner case 110. In this preferred embodiment, the outer side of the second inner case 120 can be in direct contact with the inner side of the first inner case 110.

The second inner housing 120 may include a plate-like or disc-like base portion, but may have appropriate recesses, protrusions, bends, etc. provided thereon, which may facilitate engagement with the first inner housing 110, securement thereof, mounting of other components thereon, disengagement thereof from the first inner housing 110, etc. For example, as shown in fig. 7, a support member for supporting the humidifying element 130 from the bottom may be provided on the second inner case 120.

Further, the second inner case 120 may be further provided with a raised portion at the periphery thereof on the basis of the base portion for generating a volume capacity capable of receiving liquid (e.g., condensed water) dropped therein in the air treatment device 100. The height of the elevation may be small, as long as it is sufficient to receive a certain amount of liquid.

Preferably, the second inner case 120 may be integrally formed of a soft material. In some embodiments, the first and second inner cases 110 and 120 may be made of the same material, such as a foaming material or a soft resin. In other embodiments, the material hardness of the second inner housing 120 may be greater than the hardness of the first inner housing 110. Here, the strength of the second inner case 120 may be greater, thereby better supporting the temperature adjusting element 140 and the humidifying element 130, and also enabling water storage.

In an advantageous embodiment, as best shown in fig. 4-5, the edge of the inner side wall 112 of the first inner housing 110, particularly on the edge of the inner side wall 112 near the bottom thereof, is provided with a step 114 for the second inner housing 120 to nest within the step 114. The purpose of this step 114 is to allow the second inner housing 120 to engage very snugly with the bottom of the first inner housing 110 while also simplifying the engagement process thereof and also limiting the position of the second inner housing 120 in the bottom of the first inner housing 110, i.e. not protruding beyond this step 114.

The step 114 may be provided on at least the inner sides of a pair of side walls, preferably on the inner sides of all side walls, for example extending one revolution around the entire circumference. The width of the stepped portion 114 may be designed to be small so as not to waste the space inside the inner case, and in particular, the air flow inside may be made as unobstructed as possible.

In the embodiment shown in fig. 1, a stopper 154 may be provided at one end of the humidifying element mounting portion 150, against which stopper 154 the humidifying element 130 may be mounted in place. The stop block 154 may help to further improve the airflow tightness of the inner housing by reducing undesirable spacing.

In addition, the first inner case 110 may be provided with an access opening for convenience of operation or observation by a serviceman. The access opening is advantageously provided on one side wall of the first inner housing 110.

(humidifying element)

As previously described, the humidifying element 130 is provided in the air flow path from the air inlet 182 to the air outlet 184. The humidifying element 130 is mainly used to humidify the air flowing therethrough to improve the comfort or purpose of the user. In the present utility model, the humidifying element 130 may be provided on the inner housing.

The term "disposed on" the inner housing herein does not exclude that the humidifying element 130 may be at least partially located (e.g., protruding) inside the inner housing, such as in an internal air flow path, but that the humidifying element 130 is at least in contact with or engaged with the inner housing. In some embodiments, the humidifying element 130 may be disposed on at least one, and in particular both, of the first inner housing 110 and the second inner housing 120.

In some embodiments, as shown in fig. 2-3, the top of the first inner housing 110 may be provided with an opening for receiving the top of the humidifying element 130. In particular, the opening at the top may form the humidifying element mounting portion 150, and the humidifying element 130 may be embedded within the humidifying element mounting portion 150.

In other embodiments, the top of the first inner case 110 is provided with an inner recess (not shown) in which the humidifying element 130 may be disposed. Therefore, in these embodiments, the structure for receiving the humidifying element 130 at the top of the first inner case 110 is not an open structure as described above, but a non-open structure with a concave top is utilized to receive the humidifying element 130, so that the sealing performance can be further improved (but such a concave portion may also be referred to as a humidifying element mounting portion 150).

Advantageously, the humidifying element 130 is movable along its length (in its maximum dimension) along the humidifying element mount 150. This is very advantageous for replacement, maintenance, etc. of the humidifying element. To facilitate this movement, a humidifying element guide 156 for sliding humidifying element 130 into the opening in the top is schematically shown in fig. 2.

For better support of the humidifying element 130, the second inner housing 120, in particular a plate-like or plate-like base portion thereof, may also be provided with a recess for receiving or supporting the bottom of the humidifying element 130. In other embodiments, a separate support member may be provided on the base portion of the second inner housing 120, which may be assembled to, e.g., snapped onto, the second inner housing 120. In addition to supporting the humidifying element 130, the support member may also include a rail structure similar to the humidifying element rail 156 above to facilitate mounting of the humidifying element 130 thereto. In addition, the support members 152 may include other mechanical structures, such as everting flanges or the like, that facilitate mounting of the inner housing to the outer housing.

Preferably, the top or top wall of the first inner case 110 may have a thickness at the humidifying element mounting portion 150 that is greater than the thickness at other locations of the top or top wall of the frame. In the case where the humidifying element 130 is fitted to the humidifying element mounting portion 150, the contact area between the humidifying element 130 and the humidifying element mounting portion 150 can be increased by increasing the thickness, so that the mounting stability of the humidifying element 130 is significantly improved while maintaining the structural strength of the humidifying element mounting portion 150 or the opening portion of the top portion high.

In the present utility model, the humidifying element 130 may directly introduce municipal water, or may supply water through a water supply part (e.g., including a water tank, associated piping, etc.) also provided inside the inner case. The water supply portion mounting portion 160 is clearly shown in fig. 3, and a water supply portion fixing plate has been disposed in the water supply portion mounting portion 160.

In an advantageous embodiment, the humidifying element 130 may be a wet film humidifier, which includes a humidifying core. For example, the humidifying core may be formed by stacking a plurality of moisture permeable films (not shown). Water from the water supply portion may be injected into the humidifying core portion through a water inlet port (not shown). During the air flow through the humidifying core, the air comes into contact with the water in the humidifying core, thereby being humidified. Those skilled in the art will appreciate that the humidifying element 130 may also be a spray humidification, steam humidification, wheel humidification, ultrasonic humidification, etc. The air treatment device 100 of the present utility model may have different corresponding structures for different types of humidification modes, and will not be described herein.

It will be appreciated that a plurality of humidifying elements 130 or a plurality of humidifying cores are shown in fig. 5-6, while only one humidifying element 130 is shown in fig. 7 for the sake of clarity in the illustration of the support element 152.

(temperature adjusting element)

As previously mentioned, a temperature regulating element 140 is also provided in the air flow path from the air inlet 182 to the air outlet 184 for regulating the temperature of the air flowing through it, in particular for heating it. As described above, the temperature regulating element 140 may be configured as a heat exchanger or an electric heater. The temperature regulating element 140 is arranged upstream of the humidifying element 130, seen in the air flow direction, i.e. the air may be subjected to temperature regulation before being humidified. It should be noted, however, that although the air treatment device 100 of the present utility model includes the temperature adjustment element 140 and the humidifying element 130, it does not represent that every time the air flows into the air treatment device 100 must be subjected to temperature adjustment and humidification, but only the possibility of such treatment is provided.

Preferably, a temperature adjusting element mounting portion 170 is provided on at least one of the first inner case 110 and the first outer case. In the embodiment shown in fig. 1, a temperature adjusting element mounting portion 170 is provided on the first inner housing 110, which is configured as a protrusion extending from the inner top surface 116 of the first inner housing 110 toward the center of the first inner housing 110. Although the tab is shown in fig. 1 as extending continuously along the interior top surface 116 between a pair of opposing side walls, it is contemplated that the tab may be configured in multiple segments that may abut one another or be spaced apart from one another. Preferably, the protrusions may protrude more than 2 millimeters relative to the inner top surface 116. The protrusion may help to prevent undesired displacement of the temperature regulating element 140 after it is mounted at the temperature regulating element mounting portion 170. In addition, the temperature adjustment element mounting portion 170 (e.g., in the form of a protrusion) may be further configured in a ramp structure to facilitate installation and rapid drainage.

While various embodiments of the present utility model have been described above, each structure and combination thereof in the embodiments are examples, and the addition, omission, substitution and other changes of the structure can be made within the scope not departing from the gist of the present utility model. The present utility model is not limited to the embodiments.
