Description

air handling unit

Technical field

The utility model relates to an air treatment device.

Background technique

In order to improve the air quality in closed indoor environments, various air treatment devices are currently on the market. For example, a humidification device is known. The humidification device may include, for example, an outer shell and a humidification component housed in the outer shell. On the one hand, since the air flow paths are arranged inside the outer casing, air leakage is easy to occur between the air flow paths. On the other hand, the walls of the outer casing are also spliced together, so the outer casing itself may also have air leakage problems. This air leakage or air leakage will significantly affect the insulation effect of the air handling device, and may even cause the risk of condensation.

In order to improve the sealing performance of the humidification device, it is known that a heat preservation component can be provided in the outer shell of the humidification device, and the heat preservation component includes a plurality of heat preservation pieces. These insulation parts are independent of each other and can respectively insulate the upper top plate and the lower bottom plate of the outer shell.

However, since this kind of insulation is installed separately, the sealing effect is very limited, and there is still a certain possibility of air leakage in the humidification device. For this purpose, it is known that the connections between the individual insulation elements need to be specially sealed. In addition, the assembly of multiple insulation components is also time-consuming and labor-intensive. For example, they need to be installed in alignment with each other, or special tools are used for installation, etc.

Utility model content

In order to improve the sealing performance of the housing of the air treatment device, the utility model relates to an air treatment device, which includes an outer shell that encloses a receiving space. The air treatment device also includes an inner shell, and the inner shell includes a first inner The shell and the second inner shell; the first inner shell is integrally formed into a frame with an opening at the bottom, and an air inlet and an air outlet are provided on a pair of side walls of the frame; the second inner shell covers the first inner shell The opening at the bottom of the casing; the outer surfaces of the first inner casing and the second inner casing are in contact with the inner surface of the outer casing; on the path from the air inlet to the air outlet, temperature regulators are sequentially provided on the inner casing. elements and humidification elements.

With the above air treatment device, since the first inner shell is integrated into the frame, compared with the solution of assembling the shell from different shell parts, gaps caused by assembly (for example, splicing) can be reduced and the durability of the shell can be improved. Sealing, reducing air leakage, thereby improving the insulation effect of the air handling unit and minimizing the risk of condensation.

Preferably, a step portion is formed on an inner side wall edge of the first inner shell, and the second inner shell is embedded in the step portion.

With the help of the step portion, the second inner housing can be easily installed in the opening of the bottom of the first inner housing. By embedding the second inner shell into the step portion, the sealing performance of the inner shell can be further improved. The design of the step portion is also simple and can be formed integrally when manufacturing the first inner casing.

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

The detection unit installation part can be used to monitor the air treatment conditions of the air treatment device, such as humidification conditions, temperature adjustment conditions or other physical parameters. Arranging the detection unit installation part on the side wall with the air inlet and/or the air outlet can make the installation structure very simple and simplify the processing of the inner shell.

Optionally, the top of the first inner housing is provided with an opening, the opening on the top forms a humidifying element installation portion, and the humidifying element is embedded in the opening on the top.

By providing an opening on the top of the first inner housing to form a humidifying element installation portion, the replacement and maintenance of the humidifying element can be facilitated. By embedding the humidifying element in the opening, the sealing performance of the housing can be improved while facilitating installation.

In particular, the humidifying element can move along the humidifying element mounting portion in the length direction.

With this kind of movement, the maintenance, installation and replacement of humidification elements become easier. In addition, moving the humidifying element along the humidifying element mounting portion also makes the entire movement very stable.

In particular, the thickness of the humidification element mounting portion is greater than the thickness of other positions of the top wall of the frame.

Thus, the contact area between the humidifying element installation portion or the opening at the top of the first inner housing and the humidifying element can be increased, so that the installation is very stable and the strength of the opening remains high.

More preferably, one end of the humidification element mounting portion has a limiting block.

Since the humidification element can be mounted in place against the stop, it can help to further improve the airflow tightness of the inner housing by reducing undesirable spacing.

In addition, the top of the first inner housing is provided with an inner recess, and the humidifying element is disposed in the inner recess.

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

More advantageously, at least one of the first inner shell and the second inner shell is provided with a temperature control element mounting portion, and the temperature control element mounting portion has a slope structure.

Providing a temperature-regulating element installation portion on the inner shell can facilitate the installation of the temperature-regulating element. Designing the installation part of the temperature regulating element into a slope structure can facilitate the drainage of the temperature regulating element itself.

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

Setting the inspection port can be used to facilitate maintenance personnel to operate or observe without opening the air handling device, and arranging it on a side wall of the first inner shell will not cause trouble for the staff due to the installation of certain components. vision is blocked.

It is particularly advantageous if the first inner housing is formed in one piece from a soft material.

Integrated molding with the help of soft materials can improve the thermal insulation of the inner shell and reduce heat conduction. At the same time, the possible deformation can be used to make the fit between the components installed on the first inner shell and the first inner shell closer. Closer and tighter, thereby further improving sealing performance.

It is also advantageous if the second inner housing is formed in one piece from a soft material. As a result, the second inner shell can be more closely joined to the first inner shell to further improve the sealing performance of the inner shell, while also improving the thermal insulation of the inner shell and reducing heat conduction.

For example, the soft material used for the first inner shell and/or the second inner shell is foam material or soft resin.

Foam materials or soft resin are both lightweight and have good thermal insulation properties. In addition, the processing of this material is also convenient, for example, it is easier to mold it into one piece.

Preferably, the outer side surfaces of the first inner housing and the second inner housing match the shape of the inner side of the outer housing.

By matching the shape of the outer side of the inner casing to the inner side of the outer casing, a compact layout can be achieved by making full use of the space structure.

In addition, the scope of the present invention is not limited to the following embodiments and modifications, and can be arbitrarily modified within the scope of the technical idea of the present invention. In addition, in the following drawings, in order to make each structure easy to understand, the actual structure may be different from the scale, number, etc. of each structure.

In the present invention, the terms "top", "top" or other terms related to the orientation "top", such as "top plate" and the terms "bottom", "bottom" or other terms related to the orientation "bottom" are all relative terms. It is only used to facilitate the description of the structure and function of the present utility model. Therefore, during the use of the air handling device, these relative orientation terms do not limit the actual physical location of the air handling device. For example, "top" does not mean absolutely above, and "bottom" does not mean absolutely below, such as more Close to the absolute ground.

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

Furthermore, the terms "inside", "inside" and "outside", "outside" are generally absolute positions, i.e. "inside" is within "outside" and "outside" is outside "inside" unless otherwise stated.

Although an air treatment device is described in the present invention, it should be understood that it can be understood as any device that treats air. This treatment includes, but is not limited to, filtration, temperature adjustment (including heating, cooling or combinations thereof), humidity adjustment (for example, humidification), fragrance addition, etc.

(The overall structure of the air handling device)

According to the present invention, the air treatment device 100 includes an outer casing. In general, an outer casing refers to an independent casing component, even if its walls or any other part is constructed as a multi-layered structure containing a hollow structure. The outer shell can usually be made of resin, metal material or polymer, and encloses an internal accommodation space. Although not shown in the drawings, the outer casing is preferably rectangular parallelepiped. The air treatment device 100 can be installed at a desired installation location through its outer shell, such as hanging on a vertical indoor wall or hanging on an indoor ceiling.

In the above-mentioned accommodation space, the air treatment device 100 includes an inner housing. In each embodiment of the present invention, the inner shell is in contact with the outer shell. Specifically, the outer surface of the inner housing is in contact with the inner surface of the outer housing. At the contact position, there is no gap between the inner housing and the outer housing. Here, the term "contact" includes partial contact, for example, a part of the outer side of the inner housing is in contact with the inner side of the outer housing, and also includes complete contact, for example, the entire outer side of the inner housing is 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, the inner side of the wall of the outer housing.

As exemplarily shown in Figures 1-6, the inner housing is generally rectangular in shape. In particular, the interior of the inner housing of the present invention forms a gas flow path of the air treatment device 100 . Specifically, the air inlet 182 and the air outlet 184 of the air treatment device 100 are provided on the inner housing. Here, the term "air inlet" refers to an inlet for introducing air into the air treatment device 100, and an "air outlet" refers to an outlet for discharging treated air out of the air treatment device 100. In the present invention, the air inlet 182 and the air outlet 184 at least include openings provided on the inner shell, but may also include related air outlet components provided on the openings.

Advantageously, the side wall where at least one of the air inlet 182 and the air outlet 184 is located has a detection unit installation part 186 for detecting the air treatment conditions of the air treatment device 100, such as humidification conditions, temperature adjustment conditions or other physical parameters. monitor. As shown in FIG. 1 , the detection unit installation part 186 is adjacent to and communicates with the air outlet 184 , that is, the detection unit installation part 186 is also formed on the side wall where the air outlet 184 is located.

On the gas flow path from the air inlet 182 to the air outlet 184, the air treatment device 100 also includes a temperature regulating element 140. The temperature regulating element 140 is disposed on the inner shell and is used to control the flow from the air inlet 182 to the air outlet 184. air flow for temperature regulation. Preferably, the temperature regulating element 140 may be a heat exchanger (the heat exchanger may include a heating medium loop and a refrigerant loop, for example) or an electric heater for heating the air entering the air treatment device 100 to achieve Ideal temperature (e.g., suitable for subsequent humidification treatment).

Downstream of the temperature regulating element 140, a humidifying element 130 is also provided on the inner shell for humidifying the air flowing through. Here, the term "downstream" is relative to the gas flow path, that is, the downstream elements are closer to the air outlet 184 than the upstream elements. In other words, on the path from the air inlet 182 to the air outlet 184, the temperature regulating element 140 and the humidifying element 130 can be disposed in sequence on the inner shell. It is worth noting that in the present invention, the air treatment device 100 may also include other functional components to perform other treatments on the air in addition to regulating and humidifying.

According to the present invention, a top plate 190 can also be provided on the inner shell, especially at the top, for further covering the seams provided on the inner shell to improve the sealing performance, and the top plate 190 can also help the inner shell. The connection or installation between the shell and the outer shell. Preferably, the top plate 190 covers the humidification element mounting portion 150 formed by the first inner housing 110 .

(Structure of inner shell)

In the present invention, the inner housing is a separate housing independent of the outer housing. The inner shell may include one or more layers. The inner housing includes a first inner housing 110 and a second inner housing. As mentioned above, the outside of the inner housing is in contact (at least partially) with the inside of the outer housing. Preferably, the entire outside of the inner housing is in contact with the inside of the outer housing. More preferably, the entire outside of the inner housing is in contact with the entire inside of the outer housing.

In particular, the outer surface of the inner housing can match the shape and size of the inner surface of the outer housing. In this case, there is basically no obvious gap between the inner shell and the outer shell, and they are in close contact with each other. For example, in the case where the outer casing is rectangular, the inner casing can also be rectangular, with matching shapes and sizes on each side. It is worth noting that gaps due to minor dimensional errors or due to components or devices installed on the inner shell are not within the scope of "obvious gaps".

The inner housing according to the present invention includes a first inner housing 110 and a second inner housing 120 . The first inner housing 110 is integrally formed as a frame having an opening 118 at the bottom, as best seen in FIGS. 1 and 5 . Here, the term "one-piece molding" means that the first inner housing 110 is one-piece or integral, rather than being assembled from multiple parts as in the prior art. Compared with a frame assembled from different components, the integrally formed frame can significantly reduce gaps caused by assembly (eg, splicing), thereby improving the sealing performance of the air treatment device 100 and reducing air leakage. In addition, it can be understood that although it is described as a "frame", this does not mean that the first inner housing 110 is in the shape of a wire frame, but that each side (for example, the top surface, the side surface) at least includes a continuously extending section. For example, continuously extending plate sections, although it is possible to provide a plurality of openings spaced apart from one another in these sections.

The above-mentioned first inner shell 110 may be formed of, for example, a soft material. The soft material is preferably a foam material, and other resin-based soft materials are also suitable. Suitable foam materials include polystyrene (EPS), and suitable soft resin materials include ABS, PP, HIPS, POM, etc. Preferably, the second inner shell 120, which will be described in detail below, can also be made of soft material. In the present invention, the term "soft material" is a concept opposite to rigid or rigid materials, which are generally lighter in weight and have a certain thermal insulation effect (not as easy to conduct heat as metal). Such soft materials may deform when pressure is applied (such as when inserting a component), which may also help create a tight fit with the component 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 housing 110 , especially on the side walls opposite each other, as exemplarily shown in FIGS. 1-3 . The shape and size of the air inlet 182 and the air outlet 184 can be designed according to the air flow required by the air treatment device 100, which will not be described again here. Although described above as having the opening 118 at the bottom, the first inner housing 110 may also be provided with additional openings at other locations, such as for mounting various components. But only the aforementioned opening at the bottom is used to cooperate 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 invention, the second inner shell 120 covers the opening 118 to an extent that does not substantially cause air leakage in the air treatment device 100 . Here, the term "covering" is intended to cover the opening 118 at the bottom, but the method of covering is not specifically limited (including but not limited to snapping, plugging, bonding, etc.). This covering can further improve the sealing performance of the air treatment device 100 . In some embodiments, the second inner housing 120 can be directly snapped onto the first inner housing 110 to cover the opening 118 .

Preferably, the opening 118 at the bottom of the first inner housing 110 substantially occupies the entire bottom range, that is, the size of the opening 118 is approximately equal to or slightly smaller than the bottom of the first inner housing 110 . In this case, the size of the second inner housing 120 may be approximately equal to the size of the opening 118 at the bottom of the first inner housing 110 . However, it can be understood that the fact that the second inner housing 120 covers the opening 118 at the bottom of the first inner housing 110 does not mean that the second inner housing 120 must constitute the first inner housing 110, especially the first inner housing 110 in the shape of a rectangular parallelepiped. The outermost boundary of the inner housing 110, for example the second inner housing 120, in the opening 118 of the bottom, may be directed inwardly (i.e., towards the bottom formed by the side walls of the first inner housing 110) with respect to the outermost boundary of the bottom formed by the side walls of the first inner housing 110. The center of the frame formed by the inner shell 110 is recessed for a certain distance. Of course, it is preferable that the second inner housing 120 forms the outermost boundary of the bottom of the rectangular parallelepiped-shaped first inner housing 110 . In this preferred embodiment, the outside of the second inner housing 120 can directly contact the inside of the first inner housing 110 .

The second inner shell 120 may include a plate-shaped or disc-shaped base portion, but may be provided with appropriate concave portions, convex portions, curved portions, etc., and these features may facilitate its joining with the first inner shell 110. Fixing facilitates the installation of other components thereon, facilitates its detachment from the first inner housing 110, and so on. For example, as shown in FIG. 7 , a support member may be provided on the second inner housing 120 for supporting the humidification element 130 from the bottom.

In addition, the second inner housing 120 may also be provided with a raised portion at its periphery based on the base portion for generating a chamber capable of receiving liquid (for example, condensed water) dripping into the air treatment device 100 . Volume capacity. The height of the rising part can be smaller, as long as it can accommodate a certain amount of liquid.

Preferably, the second inner shell 120 may be integrally formed of soft material. In some embodiments, the first inner shell 110 and the second inner shell 120 may be made of the same material, such as foam material or 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 shell 120 will be greater, thereby better supporting the temperature regulating element 140 and the humidifying element 130, and also achieving water storage.

In an advantageous embodiment, as best shown in Figures 4-5, a step portion 114 is provided on the edge of the inner side wall 112 of the first inner housing 110, especially on the edge of the inner side wall 112 near the bottom, for The second inner shell 120 is embedded in the stepped portion 114 . The purpose of providing the step portion 114 is to enable the second inner shell 120 to be very closely connected to the bottom of the first inner shell 110 , and at the same time to simplify the joining process, and to also ensure that the second inner shell 120 is connected to the bottom of the first inner shell 110 . The position of the bottom of the inner shell 110 is limited, that is, it does not protrude beyond the step portion 114 .

The step portion 114 can be provided on at least the inner side of a pair of side walls, preferably can be provided on the inner side of all side walls, for example, it can extend along the entire circumference. The width of the step portion 114 can be designed to be smaller so as not to waste space inside the inner casing, and in particular, to allow the internal air flow to be unobstructed as much as possible.

In the embodiment shown in FIG. 1 , a limiting block 154 may be provided at one end of the humidifying element mounting part 150 , and the humidifying element 130 may be installed in place against the limiting block 154 . The stop 154 may help further improve the airflow tightness of the inner housing by reducing undesirable spacing.

In addition, the first inner housing 110 may be provided with an access port to facilitate maintenance personnel to operate or observe. The access opening is advantageously provided on a side wall of the first inner housing 110 .

(humidification element)

As mentioned above, the humidifying element 130 is provided on the air flow path from the air inlet 182 to the air outlet 184 . The humidification element 130 is mainly used to increase the humidity of the air flowing through it, so as to improve the user's physical comfort or purpose. In the present invention, the humidification element 130 can be disposed on the inner shell.

Here, the term "disposed on the inner housing" does not exclude that the humidifying element 130 may be at least partially located (eg, protruded) inside the inner housing, such as on an internal air flow path, but the humidifying element 130 is at least in contact with the inner housing. The inner shell is in contact with or engaged with it. In some embodiments, the humidification element 130 may be provided on at least one, particularly both, of the first inner housing 110 and the second inner housing 120 .

In some embodiments, as shown in FIGS. 2-3 , the top of the first inner housing 110 may be provided with an opening for receiving the top of the humidification element 130 . In particular, the opening at the top may form a humidification element installation part 150, and the humidification element 130 may be embedded in the humidification element installation part 150.

In other embodiments, the top of the first inner housing 110 is provided with an inner recess (not shown), and the humidifying element 130 can be disposed in the inner recess. Therefore, in these embodiments, the structure at the top of the first inner housing 110 for receiving the humidification element 130 is not an open structure as described above, but a non-open structure with a concave top is used to receive the humidification. element 130, so that the sealing performance can be further improved (but this inner recess can also be called the humidification element mounting part 150).

Advantageously, the humidifying element 130 is movable along its length direction (in the direction of its largest dimension) along the humidifying element mounting portion 150 . This is very convenient for replacement and maintenance of humidification components. To facilitate this movement, a humidifying element guide 156 for sliding the humidifying element 130 into the opening in the top is schematically shown in Figure 2.

In order to better support the humidifying element 130, the second inner housing 120, especially its plate-shaped or disk-shaped base portion, 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 , and the support member may be assembled to, for example, snapped onto the second inner housing 120 . In addition to supporting the humidification element 130, the support member may also include a rail structure similar to the humidification element rail 156 above to facilitate installation of the humidification element 130 thereon. In addition, the support element 152 may also include other mechanical structures that facilitate mounting of the inner housing to the outer housing, such as everted flanges or the like.

Preferably, the thickness of the top or top wall of the first inner housing 110 at the humidifying element mounting portion 150 may be greater than the thickness of the top or top wall of the frame at other locations. When the humidification element 130 is embedded in the humidification element installation part 150 , the contact area between the humidification element 130 and the humidification element installation part 150 can be increased by increasing the thickness, thereby significantly improving the installation stability of the humidification element 130 Improve, while maintaining the structural strength of the humidification element installation part 150 or the opening part at the top relatively high.

In the present invention, the humidification element 130 can directly introduce municipal water, or can provide water through a water supply part (for example, including a water tank, related pipelines, etc.) also provided inside the inner housing. A water supply installation part 160 in which a water supply fixing plate has been arranged is clearly shown in FIG. 3 .

In an advantageous embodiment, the humidification element 130 may be a wet film humidifier including a humidification core. For example, the humidification core may be formed by stacking a plurality of moisture-permeable films (not shown). Water from the water supply part can be injected into the humidification core through a water inlet port (not shown). As the air flows through the humidification core, the air comes into contact with the water in the humidification core, thereby being humidified. However, those skilled in the art can understand that the humidification element 130 can also be spray humidification, steam humidification, rotary humidification, ultrasonic humidification, etc. The air treatment device 100 of the present invention can be provided with different corresponding structures for different types of humidification methods, which will not be described again here.

It can be understood that in FIGS. 5-6 multiple humidification elements 130 or multiple humidification cores are shown, while in FIG. 7 only one humidification element 130 is shown in order to illustrate the support element 152 more clearly.

(Temperature regulating element)

As mentioned above, a temperature regulating element 140 is also provided on the air flow path from the air inlet 182 to the air outlet 184 for regulating the temperature of the air flowing through it, especially for heating it. As mentioned above, the temperature control element 140 can be configured as a heat exchanger or an electric heater. Viewed along the air flow direction, the temperature regulating element 140 is disposed upstream of the humidifying element 130, that is, the air can undergo temperature regulation first and then be humidified. However, it should be noted that although the air treatment device 100 of the present invention includes a temperature control element 140 and a humidification element 130, it does not mean that every time the air flows into the air treatment device 100, it must be adjusted and humidified, but it is possible to do so.

Preferably, a temperature regulating element mounting portion 170 is provided on at least one of the first inner housing 110 and the first outer housing. In the embodiment shown in FIG. 1 , a temperature control element mounting portion 170 is provided on the first inner housing 110 and is configured to extend toward the first inner housing 110 from the inner top surface 116 of the first inner housing 110 . 110 centrally extending tab. Although the protrusion is shown in FIG. 1 as extending continuously along the inner top surface 116 between a pair of opposing side walls, the protrusion may also be constructed in multiple segments, which may be adjacent to each other or spaced apart from each other. Preferably, the protrusion may be raised relative to the inner top surface 116 by more than 2 mm. The protrusion may help prevent undesired displacement of the temperature control element 140 after it is installed at the temperature control element mounting portion 170 . In addition, the temperature control element mounting portion 170 (for example, in the form of a protrusion) can be further configured as a slope structure to facilitate installation and facilitate rapid drainage.

Various embodiments of the present invention have been described above. However, each structure and combination thereof in each embodiment is an example, and additions, omissions, substitutions, and other changes of structures can be made without departing from the gist of the present invention. . Moreover, the present invention is not limited by the embodiment.
