Description

Technical Field

[0001] The present application relates to the field of air handling equipment, and in particular to the structure and arrangement of a sensor assembly in the air handling equipment. Background Art

[0002] Air treatment devices are widely used in people's living and working scenes. They are used to adjust the temperature, humidity, carbon dioxide content, PM2.5 concentration and other indicators of the ambient air to improve people's physical comfort.

[0003] Some types of air handling equipment include full heat exchangers and humidifiers, which are equipped with a full heat exchange core. The air discharged to the outside and the air introduced into the room can exchange heat and water vapor in the full heat exchange core, so that the air introduced into the room has more optimal temperature and humidity conditions. The air handling equipment has an equipment housing, and the full heat exchange core is housed in the equipment housing. The equipment housing is provided with air inlets such as fresh air inlets and return air inlets, as well as air outlets such as supply air inlets and exhaust air outlets. Outdoor air enters the air handling equipment from the fresh air inlet, flows through the full heat exchange core and filters arranged on the air path, undergoes humidification, heat exchange, filtration and other processes, and is then sent into the room through the supply air outlet. Indoor air can enter the air handling equipment from the return air inlet, be processed by the full heat exchange core and filters, etc., and then be discharged to the outside through the exhaust outlet.

[0004] The air handling equipment includes a sensor component that integrates multiple different sensors. These sensors are used to detect quality indicators such as temperature, humidity, carbon dioxide content, PM2.5 concentration, etc. of the air entering the air handling equipment.

[0005] Typically, sensor assemblies installed within the equipment housing, particularly individual sensors, are installed facing the air inlet. This type of sensor assembly presents some issues during use, particularly when some sensors malfunction and require repair or replacement. Operators often find it difficult to remove the sensors from the air handling equipment housing due to the limited size of the air inlet and obstructions from other structures near the air inlet.

[0006] Therefore, in the art, there is a need to improve the structure of air handling equipment, and in particular, there is a need to improve the installation structure and arrangement orientation of the sensor assembly to facilitate the maintenance and replacement of the sensor. Utility Model Content

[0007] This application is made to solve the technical problems existing in the above-mentioned prior art. The purpose of this application is to provide an air treatment device with an improved structure, in which the sensor can be easily repaired and replaced.

[0008] The air handling equipment of the present application includes: an equipment housing, an air inlet and an air outlet are provided on the equipment housing, and an air flow path is formed between the air inlet and the air outlet; at least one inspection port is formed on the equipment housing; a full heat exchange core assembly, the full heat exchange core assembly includes a full heat exchange core, the full heat exchange core is provided between the air inlet and the air outlet, and is located on the air flow path; and a sensor assembly is provided between the air inlet and the full heat exchange core. The sensor assembly includes a mounting base and a plurality of sensors mounted on the mounting base, wherein the mounting base is formed with a mounting port, the mounting port facing the interior space of the equipment housing.

[0009] In this air handling equipment, by setting the mounting opening of the mounting base to face the internal space of the equipment shell, the operator can reach into the equipment shell from the inspection opening, then reach the mounting base from the inside of the equipment shell, and conveniently disassemble and assemble the sensor from the inside of the equipment shell.

[0010] Preferably, the mounting port is positioned between the air inlet and the heat exchange core assembly, so that the air can flow through the sensor located on the mounting port before entering the heat exchange core assembly, making the measurement of the air more accurate.

[0011] Preferably, the device housing includes an inner housing and an outer housing, and the mounting base is fixedly connected to at least one of the inner housing and the outer housing.

[0012] Regarding the location of the inspection port, the inspection port may be provided at at least one of the following locations on the equipment housing: on the top plate of the equipment housing, on the bottom plate of the equipment housing, and on the side plate of the equipment housing adjacent to the air inlet.

[0013] Preferably, the multiple sensors include a PM2.5 sensor for detecting the content of PM2.5 particles in the air entering the device housing.

[0014] In some applications, the PM2.5 sensor needs to be installed in a specific direction. In this case, the mounting base for the PM2.5 sensor is preferably provided with a misalignment structure to ensure that the PM2.5 sensor is installed in the correct direction. For example, the misalignment structure in the mounting base includes a first shape, and the PM2.5 sensor includes a second shape, and the first shape and the second shape are complementary.

[0015] For example, in the following situations, it is necessary to install the PM2.5 sensor in a specific orientation. Specifically, the PM2.5 sensor includes a sensor air outlet, and the PM2.5 sensor is installed so that its sensor air outlet faces away from the airflow path. For example, the PM2.5 sensor is installed so that its sensor air outlet faces the side panel of the device housing adjacent to the air inlet. This ensures that the PM2.5 sensor's sensor air outlet does not directly contact the airflow flowing into the air handling device from the air inlet. This prevents the PM2.5 sensor's sensor air outlet from being affected by the high-speed airflow or turbulence generated by the airflow, helping to ensure the PM2.5 sensor's detection accuracy of the PM2.5 particle content in the air.

[0016] In a specific structure, the mounting base includes an elongated connecting portion and a first base portion and a second base portion located at two ends of the connecting portion.

[0017] Preferably, the mounting base is fixed to a side edge portion of the air inlet, thereby minimizing the obstruction of the air inlet by the mounting base.

[0018] Preferably, the mounting base is secured to the device housing via at least one of a snap-fit structure and a screw-nut structure. For example, a snap-fit protrusion is formed on the mounting base, and a snap-fit groove is formed on the device housing, into which the snap-fit protrusion can be inserted. In another example, the mounting base is secured to the device housing via a screw-nut structure. Such a structure ensures the mounting base is securely mounted on the device housing while allowing for easy installation and removal of the mounting base.

[0019] Preferably, a PM2.5 sensor is mounted on the first base portion, and a temperature and humidity sensor and a CO2 sensor are mounted on the second base portion, wherein a boss for the temperature and humidity sensor is provided on the second base portion. The provision of the boss facilitates the installation of the temperature and humidity sensor.

[0020] In this application, the air handling equipment involved may be one of a fresh air fan, a blower, and a full heat exchange device. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] To facilitate understanding of this application, the specific embodiments of the air treatment equipment of this application are described in detail below with reference to the accompanying drawings. It should be understood that the drawings illustrate only preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art may make various obvious modifications, variations, and equivalent substitutions to this application based on the embodiments shown in the drawings. Furthermore, the technical features of the different embodiments described below may be combined arbitrarily, provided that no contradiction exists.

[0061] Figure 1 The schematic perspective view of the air treatment device 100 of the present application is shown. The air treatment device 100 can be, for example, a full heat exchanger, a fresh air blower, a humidifier, an indoor unit of an air conditioner with a ventilation function, etc. The air treatment device 100 includes a device housing 110, and components such as a fan and a full heat exchange core are accommodated in the space defined by the device housing 110. Figure 1 As can be seen in FIG, the device housing 110 is formed with an installation access cover 111, which is installed on the device housing 110 in an openable and closable manner, thereby allowing the access opening on the device housing 110 to be opened and closed. In the exemplary structure shown in the figure, the access opening is formed on the bottom plate ( Figure 1In addition, depending on the actual installation site, the inspection port may also be provided at other locations of the equipment housing 110, such as on the top panel and side panels of the equipment housing 110. In the case where the inspection port is formed on the side panel, the inspection port is preferably provided on the side panel adjacent to the air inlet such as the fresh air inlet 112 and the return air inlet 114. By providing the installation inspection cover 111, an access channel for inspecting the internal components of the air handling device 100 is provided, and no other components are usually installed on the installation inspection cover 111.

[0062] The device housing 110 preferably has an inner housing and an outer housing, wherein the outer housing is made of a material such as metal and the inner housing may be made of a material such as foam.

[0063] The access cover 111 can be pivotally connected to the device housing 110 via a structure such as a pivot, or can be detachably or openably connected to the device housing 110 in other ways known in the art. Generally speaking, in the installed state, the portion of the device housing 110 shown in the figure where the access cover 111 is installed is the bottom plate facing downward. In this case, a cover anti-fall mechanism, such as a connecting rope, is preferably also provided.

[0064] In some applications, the air handling device 100 may be reversed, with the top and bottom plates of the device housing 110 interchanged. In this case, a maintenance cover 111 may be provided on the top plate of the device housing 110 to facilitate maintenance and repair of the air handling device 100 by maintenance personnel.

[0065] exist Figure 2 The air handling device 100 is shown in a plan view, wherein the bottom plate of the device housing 110 is removed, exposing the structure contained in the device housing 110. The device housing 110 includes a top plate (the top plate of the device housing 110 facing the Figure 2 On the side of the paper facing inward), the bottom plate (the side of the device housing 110 facing inward Figure 2 On the side outward of the paper), and a side panel extending between the top panel and the bottom panel. Figure 2 Air inlets and air outlets are formed on the side panels on the left and right sides. In the exemplary structure shown in the figure, there are two air inlets and two air outlets, the two air inlets are specifically a fresh air inlet 112 and a return air inlet 114, and the two air outlets are specifically a supply air inlet 113 and an exhaust air inlet 115, as will be described in more detail below.

[0066] A heat exchange core assembly is installed in the device housing 110. This assembly is located inside the housing and includes a heat exchange core 200. Furthermore, the heat exchange core assembly may further include components such as a heat exchange core mounting portion for securing the heat exchange core 200 to the device housing 110, and various filters disposed on the side surfaces of the heat exchange core 200. The heat exchange core 200 is located between the fresh air inlet 112 and the supply air inlet 113, and between the return air inlet 114 and the exhaust air inlet 115.

[0067] The full heat exchange core assembly is located in the device housing 110 at a position corresponding to the installation inspection cover 111. Thus, after opening the installation inspection cover 111, the operator can conveniently perform maintenance and replacement operations on the full heat exchange core assembly. Preferably, the size of the installation inspection cover 111 is greater than or equal to the overall size of the full heat exchange core assembly. Thus, after opening the installation inspection cover 111, the full heat exchange core assembly can be fully exposed, thereby facilitating maintenance of the full heat exchange core assembly, such as enabling operation on components such as the full heat exchange core 200 and filters provided on the side surfaces of the full heat exchange core 200.

[0068] In addition, the inspection cover 111 can be made into a flip cover structure as a whole, which can further facilitate inspection and maintenance operations.

[0069] The installation inspection cover 111 can be fixed to the device housing 110 by fixing components such as fixing screws to prevent the installation inspection cover 111 from accidentally falling. To facilitate the installation and removal of the installation inspection cover 111, the fixing components and the installation inspection cover 111 are located on the same plane.

[0070] Specifically, a fresh air inlet 112 is provided on the side panel on the left side of the figure, and a return air inlet 114 is provided on the side panel on the right side of the figure. Outdoor air can enter the air treatment device 100 through the fresh air inlet 112, and indoor air can enter the air treatment device 100 through the return air inlet 114. An air supply inlet 113 is provided on the right side panel, and an air exhaust inlet 115 is provided on the left side panel. The air inhaled from the fresh air inlet 112 is sent into the room through the air supply inlet 113 after undergoing processes such as heat exchange and water vapor exchange, and the air inhaled from the return air inlet 114 can be discharged to the outside through the exhaust inlet 115. Alternatively, in the internal circulation operation mode, indoor air is inhaled into the air treatment device 100 through the return air inlet 114, and then sent back to the room through the air supply inlet 113.

[0071] In the preferred structure shown in the figure, the fresh air inlet 112 and the supply air outlet 113 are located at two corners of the equipment housing 110 arranged opposite to each other along a diagonal line, and the return air inlet 114 and the exhaust air outlet 115 are located at two corners of the equipment housing 110 arranged opposite to each other along another diagonal line.

[0072] In addition to the above-mentioned preferred diagonal setting structure, the fresh air inlet 112 and the supply air outlet 113, as well as the return air inlet 114 and the exhaust air outlet 115 can also be set non-diagonally. For example, the fresh air inlet 112 and the supply air outlet 113 can be set near the two ends of the same side of the equipment housing 110, and the return air inlet 114 and the exhaust air outlet 115 can be set near the two ends of the opposite other side of the equipment housing 110.

[0073] The air handling device 100 is provided with an exhaust fan 121 and an air supply fan 122. The exhaust fan 121 and the air supply fan 122 can be centrifugal fans, wherein the exhaust fan 121 is connected to the exhaust port 115, and the air supply fan 122 is connected to the air supply port 113. Of course, the exhaust fan 121 can also be set near the return air port 114, and the air supply fan 122 can be set near the fresh air port 112, which is also within the scope of the present application.

[0074] Preferably, a PM2.5 filter 151 is provided between the heat exchange core 200 and the air supply fan 122 to filter out PM2.5 particles before the air enters the room. The PM2.5 filter 151 shown in the figure is generally L-shaped. In other cases, the PM2.5 filter 151 may also be straight-line shaped.

[0075] Preferably, a primary screening filter 152 is installed on at least one of the sides of the full heat exchange core 200 facing the fresh air inlet 112 and the side facing the return air inlet 114. The primary screening filter 152 can filter out relatively large particles of impurities in the air before it enters the full heat exchange core 200, so as to prevent large particles of impurities in the air from damaging the membrane-like heat exchange elements in the full heat exchange core 200.

[0076] In addition to the illustrated structure, the PM2.5 filter 151 and the primary screening filter 152 may also be disposed near the fresh air inlet 112. The PM2.5 filter 151 and the primary screening filter 152 may be, for example, activated carbon filters, electrostatic dust collection filters, and the like.

[0077] from Figure 2 As can be seen, a sensor assembly 140 is provided at the air inlet such as the fresh air inlet 112 and the return air inlet 114. The sensor assembly 140 is provided between the air inlet and the full heat exchange core 200. It can detect various air indicators such as temperature, humidity, PM2.5 content, CO2 content, etc. before the inhaled air enters the full heat exchange core 200.

[0078] Figure 3, a partial enlarged view of the air handling device 100 including the return air vent 114 is shown, in which it can be seen that the sensor assembly 140 is mounted on a side edge of the return air vent 114. By positioning the sensor assembly 140 on one side of the return air vent 114, obstruction of the return air vent 114 can be minimized.

[0079] The sensor assembly 140 includes a mounting base 141, on which at least one, usually multiple sensors can be mounted. These sensors can be selected from, for example, at least one of a PM2.5 sensor, a CO2 sensor, a TVOC sensor, a formaldehyde sensor, an odor sensor, a temperature sensor, and a humidity sensor.

[0080] Figure 4 FIG1 shows an exemplary structure of a mounting base 141 of a sensor assembly 140. The mounting base 141 includes an elongated connecting portion 142 and a first base portion 143 and a second base portion 144 at both ends of the connecting portion 142. Each sensor can be mounted on the first base portion 143 and the second base portion 144, respectively.

[0081] In the present application, a mounting opening is formed on the mounting base 141 for fixing the sensor to the mounting base 141. The mounting opening is preferably formed to face the internal space of the device housing 110. In this way, the operator is allowed to reach into the interior of the device housing 110 from the inspection opening on the device housing 110 after opening the installation inspection cover 111, and then reach the mounting base 141 inside the device housing 110, and install the sensor on the mounting base 141 from the inside of the device housing 110, or remove the sensor from the mounting base 141. Such a structure can facilitate the maintenance and replacement of the sensor. Further preferably, the mounting opening of the mounting base is positioned between the fresh air inlet 112 and the full heat exchange core assembly. As a result, the air flows through the sensor before flowing into the full heat exchange core assembly, thereby improving the accuracy of air detection.

[0082] The mounting base 141 can be fixedly mounted to the device housing 110 in a variety of ways. One method is a snap-fit fit, wherein a snap-fit protrusion is formed on the mounting base 141, for example, a flange-shaped snap-fit protrusion can be formed on the bottom of the mounting base 141. Correspondingly, a snap-fit groove is formed on the device housing 110, which is configured to receive the snap-fit protrusion. Preferably, the snap-fit protrusion and the snap-fit groove have complementary shapes, and a slight interference fit is formed between the snap-fit protrusion and the snap-fit groove to help stably secure the mounting base 141 to the device housing 110.

[0083] In addition, the mounting base 141 may be fixedly connected to at least one of the inner shell and the outer shell of the device shell 110 .

[0084] As an alternative or additional method, the mounting base 141 can also be fixed to the device housing 110 by means of screws and nuts. Specifically, at least one protrusion can be formed on the mounting base 141, and a screw hole is provided on the protrusion. A screw can pass through the screw hole and be screwed into a corresponding screw hole on the device housing 110.

[0085] As another alternative or additional method, the mounting base 141 can be fixed by a bracket 116, and the bracket 116 can preferably be formed integrally with the inner circulation damper 117, such as Figure 2 Such an arrangement helps to simplify the structure of the air handling device 100. In addition, the bracket 116 and the side plate opposite to the equipment housing 110 together form a fixed structure for accommodating the electrical component box 118.

[0086] In an exemplary embodiment, when installed, as shown, the first base portion 143 is adjacent to the top plate ( Figure 2 5 sensor is mounted thereon, and the second base portion 144 is close to the bottom plate of the device housing 110 ( Figure 2 The mounting base 141 is perpendicular to the paper and faces the viewer), on which, for example, a CO2 sensor, a temperature and humidity sensor, etc. Of course, the orientation of the mounting base 141 can be changed according to the needs of the specific installation occasion, so that the first base portion 143 and the second base portion 144 take the desired position and orientation.

[0087] Figure 5 FIG. 1 shows a schematic diagram of the assembled sensor assembly 140, wherein the sensor assembly 140 is shown in FIG. Figure 3 The side facing the return air outlet 114. A PM2.5 sensor 161 is mounted on the first base portion 143, and a CO2 sensor 162 and a temperature and humidity sensor 163 are mounted on the second base portion 144.

[0088] The PM2.5 sensor 161 includes a sensor air outlet 164. The detected air enters the PM2.5 sensor 161 through the sensor air outlet 164, thereby detecting the content of PM2.5 particles in the air. Figure 6a As shown. Figure 6a As shown, an air inlet 164 and an air outlet 166 are formed on one side of the PM2.5 sensor 161. Preferably, the PM2.5 sensor 161 is installed so that the side thereof forming the air inlet 164 and the air outlet 166 faces away from the air flow path of the air entering the device housing 110 from the return air port 114. For example, the PM2.5 sensor 161 can be installed so that its air inlet 164 and the air outlet 166 (at Figure 3The side of the first base portion 143 facing away from the observer faces the side panel of the device housing 110. This arrangement prevents the PM2.5 sensor from being affected by the high flow rate of air flowing in from the return air port 114 and affecting its ability to measure PM2.5 content. In other words, the PM2.5 sensor 161, with its air inlet 164 and exhaust port 166 facing away from the air flow path, can achieve higher measurement accuracy.

[0089] like Figure 6b As shown, when the PM2.5 sensor 161 is mounted on the first base portion 143, the surface where the air inlet 164 and the exhaust port 166 are located is aligned with the side plate of the device housing 110, or with the bracket 116 supporting the mounting base 141 (see FIG. Figure 2 ). Furthermore, an opening 147 for airflow is provided on the first base portion 143. This ensures that airflow can flow into the first base portion 143, and further ensures that airflow can flow into the PM2.5 sensor 161, thereby achieving accurate detection of airflow.

[0090] Furthermore, a mistake-proofing structure is provided on the first base portion 143, which can ensure that the PM2.5 sensor is installed in the correct orientation, for example, ensuring that the air outlet of the PM2.5 sensor faces away from the air flow path. Figure 7 A partial enlarged view of the first base portion 143 of the mounting base 141 is shown. This more clearly illustrates a first shape, such as a convex portion, formed in the first base portion 143, and a second shape, such as a concave portion, formed on the PM2.5 sensor 161. The first shape complements the second shape. When installing the PM2.5 sensor 161 on the first base portion 143, if the first and second shapes mate, the PM2.5 sensor is correctly oriented and can be successfully installed on the first base portion 143. Conversely, if the first and second shapes misalign during installation, the PM2.5 sensor is incorrectly oriented. Due to the mismatch, the PM2.5 sensor 161 will have difficulty entering the first base portion 143. This allows the operator to determine whether the orientation of the PM2.5 sensor 161 needs to be adjusted for proper installation.

[0091] The second base portion 144 is used to mount the temperature and humidity sensor and the CO2 sensor. Preferably, a boss 145 is formed on the second base portion 144. Figure 4 The boss 145 helps to mount the temperature and humidity sensor on the second base portion 144.

[0092] <Other variant structures>

[0093] The exemplary preferred structure of the present application is described above in conjunction with the accompanying drawings. Those skilled in the art can make modifications and variations based on the above structure without exceeding the scope of the present application.

[0094] For example, the sensor assembly 140 at the return air inlet 114 has been described in detail above. A sensor assembly 140 with this structure can also be installed at the fresh air inlet 112 to detect various indicators of the air drawn from the outside into the air handling device 100. Alternatively, the sensor assembly at at least one of the fresh air inlet 112 and the return air inlet 114 can be a sensor assembly 140 with the above structure.

[0095] In addition to the PM2.5 sensor 161, CO2 sensor 162 and temperature and humidity sensor 163 described above, the mounting base 141 can also be designed to install other types of sensors, such as TVOC sensors, formaldehyde sensors, odor sensors, etc.
