Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrical equipment, especially to an air detection device and air conditioning equipment. BACKGROUND

[0002] The air detection device is used for detecting various air parameters, such as air temperature, air humidity and air quality.

[0003] Based on different application scenarios, the air detection device can be used independently or configured as a functional unit on a device for adjusting air parameters, such as air conditioning equipment, to realize detection of air parameters and online adjustment of air based on the detection results.

[0004] Taking an air detection device configured with an odor detection unit and a humidity detection unit as an example, the odor detection unit and the humidity detection unit in the current air detection device are often arranged in two separate accommodation cavities, and are mainly used for sampling and detecting freely diffusing air. Due to the flow direction and flow rate of the freely diffusing air, the detection process of the air detection device is often slow. The slow detection process also makes it difficult to control the output order of the detection results, which may further cause false positives of the detection results of the air detection device. SUMMARY

[0005] To solve the above and other technical problems in the prior art, the utility model provides an air detection device and air conditioning equipment. The air in the first accommodation cavity and the second accommodation cavity has different flow rates. Under the action of the sampling air path, the flow rate of the air near the second accommodation cavity is improved, which helps to shorten the time required for the detection process.

[0006] The first aspect of the utility model provides an air detection device, which comprises: a first shell, a first air inlet and a first air outlet are arranged on the first shell respectively, a sampling air path connecting the first air inlet and the first air outlet, a first accommodation cavity connected to the sampling air path, and a second accommodation cavity connected to the sampling air path in the first shell; a humidity detection unit arranged in the first accommodation cavity; and an odor detection unit arranged in the second accommodation cavity.

[0007] In some illustrative embodiments, the first air inlet is arranged on a first wall of the first shell, and the first air outlet is arranged on a second wall of the first shell facing the first wall.

[0008] In some illustrative embodiments, the first air outlet is located on the downstream side of the humidity detection unit.

[0009] In some demonstrative embodiments, a length of the first air inlet along a first direction is greater than a width of the first air inlet along a second direction, the first direction and the second direction being transverse.

[0010] In some demonstrative embodiments, the first accommodation chamber and the second accommodation chamber are located at a downstream side of the first air inlet, and are disposed at opposite ends, which are distanced along the first direction.

[0011] In some demonstrative embodiments, the second accommodation chamber is located at an upstream side of the first accommodation chamber.

[0012] In some demonstrative embodiments, the first accommodation chamber and the second accommodation chamber are spaced apart along the first direction.

[0013] In some demonstrative embodiments, the air detection device further comprises a flow guide plate, disposed within the first air inlet, and located between the first accommodation chamber and the second accommodation chamber, the flow guide plate and the area defined by the first air inlet forming a portion of the sampling air path, to direct a portion of the air to flow along the first direction of extension of the flow guide plate, and to enter the first accommodation chamber.

[0014] In some demonstrative embodiments, the second accommodation chamber comprises an air inlet end, through which air enters the second accommodation chamber, wherein a projection of the first air inlet and a projection of the air inlet end overlap at least partially in an orthogonal projection of a plane of the air inlet end.

[0015] A second aspect of the present utility model provides an air conditioning device, comprising: a body; and an air detection device, the air detection device being disposed on the body.

[0016] In some demonstrative embodiments, the body comprises: a second housing; and a fan, disposed within the second housing and having an air duct, configured to draw a portion of air within an air exchange space outside into the air duct; a circulating air outlet, an opening disposed on a face of the second housing parallel to an axis of rotation of the fan; a panel disposed on the second housing, the panel being provided with a second air inlet and a second air outlet, the second air inlet and the second air outlet both being in communication with the air exchange space; and a joint connecting the circulating air outlet and the second air outlet.

[0017] In some demonstrative embodiments, the second housing is further provided with a third air outlet, the third air outlet being in communication with an exhaust space outside the air exchange space.

[0018] In some exemplary embodiments, the main body is configured to have a first mode of cutting off the second air inlet and the third air outlet, and a second mode of connecting the second air inlet and the third air outlet, in response to the air parameters detected by the air detection device.

[0019] In some exemplary embodiments, the air detection device is disposed on the panel; wherein the first air inlet of the air detection device is in communication with the ventilation space.

[0020] In some exemplary embodiments, the air detection device is disposed between the second air inlet and the second air outlet.

[0021] According to the air detection device and air conditioning equipment provided by the exemplary embodiment of the present invention, the flow rate of air when passing through the first accommodating chamber located in the sampling air path between the first air inlet and the first air outlet is higher than the flow rate of air passing near the second accommodating chamber, and because the first accommodating chamber and the second accommodating chamber are connected through the sampling air path, the air flow rate through the second accommodating chamber is increased under the action of the pressure difference formed by the air flow rate difference. In this way, since more air can pass through the humidity detection unit and the odor detection unit per unit time, the detection time required for the detection process can be shortened. In addition, based on the flow rate difference between the first accommodating chamber and the second accommodating chamber, it is also beneficial to control the order in which the humidity detection unit and the odor detection unit output the detection results.

For example, the expression "a system having at least one of A, B, and C" should be interpreted to include a system having at least one of A, a system having at least one of B, a system having at least one of C, a system having at least one of A and B, a system having at least one of A and C, a system having at least one of B and C, and / or a system having at least one of A, B, and C, etc. In the case of using expressions similar to "at least one of A, B, or C, etc.", it should be generally interpreted that the meaning of the expression is at least one of the items listed before the conjunction, unless otherwise clearly defined.

[0034] The air detection device will be described below in connection with an illustrative embodiment, which includes but is not limited to a standalone use, an application in an air conditioning device, or an application in other electrical appliances with air detection requirements.

[0035] For example, the air detection device can be independently arranged in a ventilation space requiring air detection.

[0036] Alternatively, the air detection device can be integrated in an air conditioning device. It should be understood that the above-mentioned integration in the air conditioning device does not mean that the air detection device is installed as a whole in the air conditioning device, but can also be arranged separately from the air conditioning device, only realizing the communication connection of the signal, for example, transmitting the air humidity and / or odor detection results detected by the air detection device to the air conditioning device in the form of a signal for processing.

[0037] The following describes an embodiment of the air detection device applied to the air conditioning device. It should be understood that the embodiment is illustrative and not limiting. Specifically, the above-mentioned air conditioning device includes but is not limited to any one of a ventilation fan with internal and external circulation modes, a fresh air machine, an integrated air conditioning device, a wall-mounted bath heater, a ceiling-mounted bath heater, and other air conditioning devices with ventilation functions.

[0038] On this basis, in order to clearly illustrate the shortcomings of the air detection device currently applied to the air conditioning device, it is assumed that the air conditioning device is applied to the use scenario of a bathroom with bathroom functions.

[0039] In this illustrative use scenario, the external circulation mode of the air conditioning device includes but is not limited to being used for quickly discharging air with odor (such as odor, smoke, and irritating odor) in the bathroom, and the internal circulation mode includes but is not limited to being used for auxiliary heating of air in the bathroom when a user is bathing.

[0040] Based on the above use scenario, when the air in the ventilation space (i.e., the bathroom) has odor, in order to enable the air conditioning device to automatically (i.e., without human interaction) switch to the external circulation mode, an air detection device with an odor detection unit (such as an optical sensor and a semiconductor sensor) can be configured on the air conditioning device to obtain the type and / or concentration of odor substances carried in the air. However, when the humidity of indoor air is too high (such as a large amount of water vapor generated during bathing), a large amount of water vapor can cause the odor detection unit to be triggered by mistake, thereby causing the air conditioning device to switch to the external circulation mode (i.e., discharging the air in the ventilation space to an external space (such as the outdoor)). In this way, the room temperature in the ventilation space (i.e., the bathroom) can be rapidly reduced, thereby causing the user to feel uncomfortable.

[0041] Based on the above shortcomings, at present, the humidity detection unit can be configured in the air detection device to detect the air humidity in the ventilation space, and the detection result of the air humidity is used as the advance judgment of the odor detection result to compensate for the insufficient detection accuracy of the odor detection result. For example, when the air humidity is too high, the air conditioning equipment can be limited to switch to the outdoor circulation mode automatically.

[0042] However, in actual use, the naturally diffused air often cannot sensitively trigger the humidity detection unit (even if the air humidity detection result is given priority to the odor detection result), so that the configured humidity detection unit loses the function of compensating for the odor detection unit, and the odor detection unit is still likely to be triggered by mistake. Therefore, how to prevent the odor detection unit from being triggered by mistake becomes a technical problem to be solved.

[0043] The utility model provides a kind of air detection device 10, refer to Figures 1 to 3 As shown in the figure, comprising first shell 11, humidity detection unit 12 and odor detection unit 13. First shell 11 is respectively provided with first air inlet 111 and first air outlet 112, and sampling air path is communicated with first air inlet 111 and first air outlet 112. First shell 11 is provided with first containing cavity 113 communicated with sampling air path, and second containing cavity 114 communicated with sampling air path is also provided in first shell 11. Humidity detection unit 12 is arranged in first containing cavity 113. Odor detection unit 13 is arranged in second containing cavity 114.

[0044] First containing cavity 113 is provided with first containing cavity air inlet end, and the so-called communication sampling air path means that first containing cavity is communicated with sampling air path by first containing cavity air inlet end, and at least part of air in sampling air path enters first containing cavity by first containing cavity air inlet end. Similarly, second containing cavity 114 is provided with second containing cavity air inlet end 1142, and second containing cavity is communicated with sampling air path by second containing cavity air inlet end 1142, that is, at least part of air in sampling air path enters second containing cavity by second containing cavity air inlet end 1142.

[0045] In some exemplary embodiments, referring to Figures 1 to 3 As shown in the figure, the first shell 11 of the air detection device 10 includes but is not limited to being directly or indirectly mounted on the external mounting base (such as being hung on the ceiling of the indoor environment), which includes the first part (such as being hidden on the ceiling) above the mounting base and the second part below the mounting base and exposed in the ventilation space (such as the indoor environment). Further, the first air inlet 111 is arranged in the second part (i.e. the right part as shown in Figure 1 The first air outlet 112 is located in the first part (located in the second shell 21, not shown in Figure 1), so that part of the air in the ventilation space can enter the first accommodating chamber 113 and the second accommodating chamber 114 through the first air inlet 111.

[0046] In this embodiment, due to convection between the first air inlet 111 and the first air outlet 112, the air velocity passing through the first accommodating chamber 113, located between the air paths of the first air inlet 111 and the first air outlet 112, is higher than the air velocity passing through the vicinity of the second accommodating chamber 114. Furthermore, because the first accommodating chamber 113 and the second accommodating chamber 114 are connected via the sampling air path, the air pressure difference created by the flow velocity difference also increases the air velocity passing through the second accommodating chamber 114. This allows more air to pass through the humidity detection unit 12 and the odor detection unit 13 (their detection ends) per unit time, shortening the detection time required. Furthermore, since there is a flow rate difference between the first accommodating chamber 113 and the second accommodating chamber 114, it is also beneficial to control the order in which the humidity detection unit 12 and the odor detection unit 13 output the detection results (that is, since the flow rate in the first accommodating chamber 113 is faster, it is beneficial for the detection results of the humidity detection unit 12 to be output before the detection results of the odor detection unit 13, which is explained in detail below).

[0047] According to the embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the first air inlet 111 is provided on the first wall 115 of the first housing 11 (as shown in FIG. Figure 4 and Figure 5 The first air outlet 112 is provided on the second wall 116 (as shown in the lower wall) of the first shell 11 facing the first wall 115. Figure 4 and Figure 5 on the upper wall shown).

[0048] According to the embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the second accommodating cavity 114 includes an air inlet end 1141 for air to enter. The orthographic projection of the plane where the air inlet end 1141 is located (as shown in FIG. Figure 5 In the projection in the z direction (ie, the projection in the up-down direction) shown in FIG. 1 , the projections of the first air inlet 111 and the air inlet end 1141 at least partially overlap.

[0049] In an illustrative embodiment, referring to Figure 4 and Figure 5 As shown, the first shell 11 is configured to be, but not limited to, a polyhedron structure with a vertical cross section that is approximately L-shaped (which can be considered a body structure formed by splicing two cubes), including Figure 5The first wall 115 at the lower portion and the second wall 116 at the upper portion are shown. Furthermore, the first accommodating cavity 113 and the second accommodating cavity 114 can be disposed within the first air inlet 111, wherein the projections of the first air outlet 112 and the first air inlet 111 are configured to at least partially overlap (i.e., partially overlap, or completely overlap).

[0050] In an illustrative embodiment, referring to Figure 4 and Figure 5 As shown, the first accommodating cavity 113 is formed above the first air inlet 111 and below the first air outlet 112 (as shown in FIG. Figure 5 The left side of the figure shows the left side of the figure), so that part of the air passing through the first air inlet 111 can pass through the first accommodating cavity 113 and the first air outlet 112 in sequence. Further, the second accommodating cavity 114 is provided in the first air inlet 111 and the first air outlet 112 along the first direction (as shown in FIG. Figure 5 The x-direction shown) is displaced (as shown in Figure 5 It should be understood that the embodiments of the present invention are not limited thereto.

[0051] For example, the first air outlet 112 can also be configured so that its orthographic projection on the plane where the first air inlet 111 is located does not overlap with the first air inlet 111 at all, that is, the air entering through the first air inlet 111 forms an S-shaped flow in the first accommodating cavity 113 and finally flows out through the first air outlet 112.

[0052] Alternatively, the first air outlet 112 is disposed in a portion of the first housing 11 outside the first accommodating chamber 113, and the first air outlet 112 is offset from the first air inlet 111 in the direction of extension of the sampling air path. Furthermore, in the direction of extension of the sampling air path, the first air outlet 112 is also located downstream of the first accommodating chamber 113 and the second accommodating chamber 114. In this way, under the convection effect formed by the first air inlet 111 and the offset first air outlet 112, the air will be accelerated to pass through the second accommodating chamber 114 and the first accommodating chamber 113 in sequence, so as to be detected by the odor detection unit 13 and the humidity detection unit 12, respectively.

[0053] According to the embodiment of the present invention, referring to Figure 4 and Figure 5 As shown, the first air outlet 112 is located at the downstream side of the humidity detection unit 12. That is, the humidity detection unit 12 can be disposed in the first accommodating cavity 113.

[0054] In an illustrative embodiment, referring to Figure 4 and Figure 5As shown, the humidity detection unit 12 is correspondingly arranged in the first accommodating cavity 113, and the odor detection unit 13 is correspondingly arranged in the second accommodating cavity 114. The humidity detection unit 12 includes, but is not limited to, at least one of a capacitive humidity sensor, a resistance humidity sensor, a dew point humidity sensor, a thermal conductivity humidity sensor, and other sensors suitable for detecting air humidity; the odor detection unit 13 includes, but is not limited to, at least one of a semiconductor sensor, an optical sensor, and other sensors suitable for detecting odor substances (such as at least one of hydrogen sulfide, ammonia, indole, and phenol) entrained in the air.

[0055] In such an embodiment, when there is an air flow (such as a spontaneous air flow above the installation base) passing near the first air outlet 112, a chimney effect is formed in the first accommodating cavity 113, so that a negative pressure is formed near the first air inlet 111, thereby sucking part of the air in the ventilation space into the first accommodating cavity 113 to be detected by the humidity detection unit 12; at the same time, in the space defined by the first air inlet 111, because the air near the first accommodating cavity 113 is sucked in faster, the air in the first air inlet 111 also forms a pressure difference, thereby promoting the air in the ventilation environment to pass through the detection position of the odor detection unit 13 (i.e. near the second accommodating cavity 114) faster.

[0056] Through the above design, without configuring an active negative pressure device for the air detection device 10, the natural flow of the air in different areas separated by the installation base (such as the ceiling) can form a flow rate difference in the first air inlet 111. Under the countercurrent action of the first air inlet 111 and the first air outlet 112, the airflow in the first accommodating cavity 113 is faster, more air can pass through in a unit of time, so that the humidity detection unit 12 is more sensitive than the odor detection unit 13. In this way, the air detection device 10 can prioritize the detection of air humidity over the detection of odor substances, so as to compensate for the second detection result output by the lagging odor detection unit 13 using the first detection result of the humidity detection unit 12, that is, to determine the air humidity in the ventilation space first, and then to detect the odor substances, so as to prevent the false triggering of the odor detection unit 13 due to excessive humidity. It should be understood that the embodiments of the present application are not limited thereto.

[0057] For example, a negative pressure device (such as a fan 24) can also be arranged in the air detection device 10, so that the negative pressure in the first air outlet 112 (including the first accommodating cavity 113) can be adjusted to actively suck air into the first air inlet 111.

[0058] It should be noted here that the collection, comparison, judgment and processing of the detection results of the odor detection unit 13 and the humidity detection unit 12 are not the protection points of the present invention. Any unit and component in the field that can obtain the above-mentioned detection results can be selected and applied.

[0059] For example, when the humidity detection unit 12 detects that the air humidity is too high (such as exceeding a preset threshold), it can output a voltage signal. When the acquisition unit configured in the air detection device 10 (or air conditioning equipment) collects the voltage signal, the actuator of the air conditioning equipment (such as the motor 241 and the solenoid valve, etc.) will no longer autonomously respond to the signal output by the odor detection unit 13 to perform actions, and will wait for interaction with the user (such as the user selecting the working mode through the control panel 22 of the air conditioning equipment) before further performing actions.

[0060] According to the embodiment of the present invention, referring to Figures 1 to 3 As shown, the first air inlet 111 is along the first direction (as Figure 1 The length along the x direction shown in FIG. Figure 1 The first direction and the second direction intersect. Preferably, the first direction and the second direction are orthogonal to each other.

[0061] According to the embodiment of the present invention, referring to Figures 1 to 3 As shown, the first accommodating chamber 113 and the second accommodating chamber 114 are located on the downstream side of the first air inlet 111 and are arranged at two ends away from each other along the first direction.

[0062] According to the embodiment of the present invention, referring to Figures 1 to 3 As shown, the second accommodating chamber 114 is located on the upstream side of the first accommodating chamber 113 .

[0063] According to the embodiment of the present invention, referring to Figures 1 to 3 As shown, the first accommodating cavity 113 and the second accommodating cavity 114 are spaced apart in the first direction.

[0064] In an illustrative embodiment, Figure 1As shown, the first air inlet 111 is configured as a substantially strip-shaped structure (i.e. the first air inlet 111 has a length and a width, or the first air inlet 111 has a long axis and a short axis). In detail, the first air inlet 111 includes but is not limited to any one of a rectangle, a rectangle-like shape, an ellipse, a runway shape, a polygon, and a special shape having different lengths and widths as a whole. Since the first air inlet 111 is set in a long and narrow shape with a length in the first direction being greater than a width in the second direction, when air enters the first air inlet, the air will be compressed, thereby increasing the flow rate of the air, making the flow rate of the air in the sampling air path higher, and further improving the detection speed of the humidity detection unit and the odor detection unit. Moreover, the first accommodating cavity 113 and the second accommodating cavity 114 can be spaced apart as far as possible in the first air inlet 111, so that the flow rate difference of the air passing through the first accommodating cavity 113 and the second accommodating cavity 114 is more obvious. Moreover, the strip-shaped first air inlet 111 not only maintains a large air inlet area, but also covers more areas of the air exchange space in the extension direction, which is also beneficial to improve the air exchange effect.

[0065] According to an embodiment of the present application, referring to Figure 4 and Figure 5 As shown, the air detection device 10 further includes a flow guide plate 117. The flow guide plate 117 is arranged in the first air inlet 111 and located between the first accommodating cavity 113 and the second accommodating cavity 114. The flow guide plate 117 and the area surrounded by the first air inlet 111 form part of the sampling air path to guide a part of the air to flow along the extension direction of the flow guide plate 117 and enter the first accommodating cavity 113.

[0066] In an exemplary embodiment, referring to Figure 4 and Figure 5 As shown, the flow guide plate 117 includes but is not limited to being integrally formed with the first housing 11. In detail, the flow guide plate 117 is located on the inner side of the first air inlet 111, and cooperates with the inner wall of the first air inlet 111 to define a semi-closed sampling air path (i.e. the lower part as shown in Figure 1 communicates with the air exchange space).

[0067] In such an embodiment, the sampling air path formed by the flow guide plate 117 and the first air inlet 111 can make the air in the above-mentioned sampling air path as little as possible to be disturbed by the air outside the first air inlet 111, so as to reduce the disturbance of the external air and avoid the formation of vortex in the sampling air path. In this way, the air in the first air inlet 111 can flow along the extension direction of the flow guide plate 117 (i.e. the left-right direction as shown in Figure 1 , that is, the first direction) from the side close to the second accommodating cavity 114 (i.e. Figure 1The air is more stably sucked into the first accommodating cavity 113. It should be understood that the embodiments of the present application are not limited thereto.

[0068] For example, the flow guide plate 117 can also be a plate-shaped structure independent of the first shell 11.

[0069] For example, the flow guide plate 117 can also be a plate-shaped structure independent of the first shell 11.

[0070] For example, the flow guide plate 117 can also be a plate-shaped structure independent of the first shell 11.

[0071] In an illustrative embodiment, referring to Figure 4 and Figure 5 As shown, based on the side-by-side arrangement of the first accommodating cavity 113 and the second accommodating cavity 114, and the flow guide plate 117 arranged between the first accommodating cavity 113 and the second accommodating cavity 114, a portion of the air can pass through the vicinity of the air inlet end 1141 of the second accommodating cavity 114 before entering the first accommodating cavity 113. Therefore, the first accommodating cavity 113 can be regarded as the downstream side of the second accommodating cavity 114 according to the flow direction of the air flow.

[0072] In an illustrative embodiment, continuing to refer to Figure 4 and Figure 5 As shown, the air detection device 10 further comprises a shielding unit. The shielding unit is arranged at the air inlet end 1141 of the first accommodating cavity 113, and is configured to block at least a portion of the liquid droplets located in the first air inlet 111 from entering the first accommodating cavity 113, and allow the air and at least a portion of the water vapor entrained by the air to pass through.

[0073] In an illustrative embodiment, referring to Figure 4 and Figure 5 As shown, the shielding unit includes but is not limited to a breathable waterproof film 27. In detail, the breathable waterproof film 27 includes but is not limited to being arranged in the air inlet hole of the air inlet end 1141 of the first accommodating cavity 113 (such as the air inlet hole shown in Figure 1 As shown, to at least partially seal the air inlet end 1141 of the first accommodating cavity 113. The breathable waterproof film 27 includes but is not limited to being made of a porous structure such as polytetrafluoroethylene, polyester film, polyurethane, polyethylene, and other films that can prevent liquid droplets and allow water vapor to pass through. Further, the shielding unit includes but is not limited to being connected to the first shell 11 by buckling, bonding, connectors, and other arbitrary means, and being unfolded along the air inlet end 1141 of the first accommodating cavity 113 to at least partially shield the air inlet end 1141 of the first accommodating cavity 113.

[0074] For example, the air inlet hole formed by the first accommodating cavity 113 can be completely closed.

[0075] Or as, the first accommodating cavity 113 formed by the air inlet hole part closed.

[0076] Again, the shielding unit can also be provided in the first air inlet 111 with the first accommodating cavity 113 (such as the air inlet hole) coincides with the position of the air inlet end 1141. Figure 1

[0077] Also, the shielding unit can be used along the first accommodating unit of the air inlet end 1141, with the air flow direction intersection (such as substantially perpendicular) set up the hard shielding structure such as water baffle.

[0078] Such embodiments, provided in the first accommodating cavity 113 of the air inlet end 1141 (such as the air inlet hole) of the shielding unit, can prevent the larger particle size droplets (such as in the shower when splashing water droplets) into the first accommodating cavity 113 resulting in the damage (such as corrosion, short circuit, etc.) of the humidity detection unit 12, but also can make the water vapor unobstructed (or considered unobstructed) through. Figure 1

[0079] It should be noted that, in the shielding unit using the breathable waterproof membrane 27 and its arrangement in the first air inlet 111, the breathable waterproof membrane 27 should be made as far away from the second accommodating cavity 114 of the air inlet end 1141, especially should not cover the air inlet end 1141 of the second accommodating cavity 114. This is because the porous membrane structure of the breathable waterproof membrane 27 is easy to retain some odor substances (such as tar, etc.) in the hole, when the air with a certain humidity through these contaminated holes, easy to cause the air to be contaminated by odor substances, thus causing the odor detection unit 13 to be triggered.

[0080] Based on the same idea, the utility model also provides an air conditioning equipment, refer to Figures 1 to 5 As shown, comprising the body 20 and air detection device 10.

[0081] In an exemplary embodiment, the humidity detection unit 12 and odor detection unit 13 in the air detection device 10 are in communication connection with other execution mechanism outside. For example, the signal output end of the humidity detection unit 12 in the air detection device 10 is connected with the collection unit (such as collection card) of the air conditioning equipment, the signal output end of the collection unit and the control unit (such as single chip microcomputer, chip, programmable logic controller, etc.) are in communication connection, and the control unit is connected with the control end of the execution mechanism.

[0082] Such embodiments, the air detection device 10 configured in the air conditioning equipment has the similar effect with the above embodiment, in addition, the execution mechanism in the air conditioning equipment body 20 can also be independently responded to the air detection device 10 for adjustment, to improve the intelligent degree of the air conditioning equipment.

[0083] ​​According to the embodiment of the present application, referring to Figures 1 to 3 , the body 20 of the air conditioning device includes a second housing 21, a fan 24, a panel 22, and a joint 23. The fan 24 is disposed in the second housing 21 and has an air duct. The fan 24 is configured to suck a portion of air in an external ventilation space into the air duct, and the second housing 21 is provided with a circulating air outlet 211 disposed on a face (e.g., a face formed by the y-axis and the z-axis shown in Figure 1 ) of the second housing 21 parallel to a rotation shaft (to be described below) of the fan 24. The panel 22 is disposed on the second housing 21, and the panel 22 is provided with a second air inlet 221 and a second air outlet 222, both of which are in communication with the ventilation space. The circulating air outlet 211 is connected to the second air outlet 222.

[0084] According to the embodiment of the present application, referring to Figure 2 , the second housing 21 is further provided with a third air outlet 212, which is in communication with an external exhaust space outside the ventilation space.

[0085] In an illustrative embodiment, referring to Figure 2 , the second housing 21 includes but is not limited to a structure configured as a substantially cuboid, and one end (e.g., the right end shown in Figure 2 ) of the second housing 21 extends in a first direction to form an elongated portion 26 in a substantially plate shape. In detail, the second housing 21 can be mounted on an external mounting base (e.g., a ceiling). Further, the second housing 21 can be hidden above the mounting base, and only the panel 22 is exposed to the top of the mounting base located in the ventilation space (e.g., a room). Among them, the panel 22 can be substantially flush with the top of the ventilation space (i.e., the display surface of the ceiling), or slightly protrude downward.

[0086] In an illustrative embodiment, referring to Figure 2 and Figure 3 , the panel 22 is disposed below the second housing 21 (i.e., on the right side as shown in Figure 2 and Figure 3 ), and the panel 22 is configured as a strip-shaped structure (e.g., a rectangle). In detail, it spans the second housing 21 and the elongated portion 26 disposed on the second housing 21. In this way, on the basis of making the panel 22 have sufficient area to dispose the second air inlet 221 and the second air outlet 222, the required width dimension of the mounting base is smaller, and the installation method is more flexible. In addition, it is more smooth in perspective effect, easy to match with the decoration style of the room, and thus more beautiful.

[0087] In some illustrative embodiments, as shown in Figure 2As shown, the fan 24 is installed in the cuboid space defined by the second housing 21. In detail, the fan 24 includes, but is not limited to, an axial fan 24, specifically including a motor 241, an impeller 242, a wind tube 245, a collector 244, a fairing 243, and a shell.

[0088] The motor 241 serves as the main power source of the fan 24 to drive the impeller 242 to rotate, thereby pushing the air around the impeller 242 to flow in the same direction as the axis; the collector 244 and the impeller 242 are sequentially arranged between the second air inlet 221 and the impeller 242 according to the direction of air flow, so as to optimize the air intake effect (such as reducing the formation of vortex) and guide the air flow into the vicinity of the impeller 242; the fairing 243 is arranged downstream of the impeller 242 to improve the stability of the air flow and reduce noise; the shell is arranged outside the above-mentioned mechanism to support other mechanisms, in addition, the shell defines an air duct with a guiding air flow function, which is preferably configured as an annular shape and is arranged substantially coaxially with the axis of the motor 241.

[0089] According to the embodiment of the present application, referring to Figure 2 As shown, the air detection device 10 is arranged on the panel 22. The first air inlet 111 of the air detection device 10 is in communication with the air exchange space.

[0090] According to the embodiment of the present application, referring to Figure 2 As shown, the air detection device 10 is arranged between the second air inlet 221 and the second air outlet 222.

[0091] In an exemplary embodiment, as shown in Figure 2 The second air inlet 221 is arranged on the portion of the panel 22 facing the fan 24, and the second air outlet 222 is arranged on the elongated portion 26 of the second housing 21. In detail, the second air inlet 221 and the second air outlet 222 are arranged in a spaced manner. Further, the air detection device 10 is arranged in the gap formed by the second air inlet 221 and the second air outlet 222.

[0092] In such an embodiment, the second air inlet 221 is arranged opposite to the fan 24, so that the distance between the second air inlet 221 and the fan 24 can be shortened, and the length of the air inlet passage can be shortened on the basis of a constant operating power of the fan 24, so that more air can be drawn into the air conditioning device; the second air outlet 222 is arranged on the lengthened portion 26, and can be visually regarded as an extension of the second air inlet 221, so that the part of the air conditioning device exposed in the ventilation space is narrower (the width requirement for the installation position is reduced), and the overall line is more extended and beautiful. On this basis, the air detection device 10 is arranged between the second air inlet 221 and the second air outlet 222, so as to realize the isolation of the air inlet and the air outlet in terms of function, reduce the air flow disturbance between each other, make the air conditioning device more compact, and make the longer panel 22 visually form a shape change and thus more beautiful.

[0093] In an exemplary embodiment, as shown in Figure 2 the body 20 further comprises a supplementary heating assembly 25 arranged in the second housing 21 at a position opposite to the second air outlet 222.

[0094] In an exemplary embodiment, as shown in Figure 2 the side wall of the second housing 21 is provided with a cover-shaped joint 23, which is configured to connect a first side wall (the right wall as shown in Figure 2 ) of the housing of the fan 24 with the second air outlet 222, so that the air is returned to the ventilation space (i.e. the indoor space) through the second air outlet 222 after being sucked and circulated by the fan 24. Further, the supplementary heating assembly 25 is arranged in the joint 23 at a position opposite to the second air outlet 222, so that the air passing through the supplementary heating assembly 25 is heated, thereby adjusting the air temperature in the ventilation space (i.e. the indoor space). The supplementary heating assembly 25 includes, but is not limited to, an electric heater (such as an electric heating wire and an electric heating rod), a heat pump, a heat exchanger and other devices suitable for heating air. It should be understood that the embodiments of the present application are not limited thereto.

[0095] In addition to arranging the supplementary heating assembly 25 upstream of the second air outlet 222 to heat the air, other devices for adjusting the air can also be arranged upstream of the second air outlet 222 (such as in the joint 23 described above).

[0096] For example, an evaporator can be arranged inside to condense part of the water vapor, thereby reducing the humidity of the air.

[0097] Or, for example, a filter material can be arranged inside to adsorb particles and part of odor substances in the air.

[0098] According to the embodiments of the present application, with reference to Figure 2As shown, the body 20 is configured to have a first mode of cutting off the second air inlet 221 and the third air outlet 212 and a second mode of conducting the second air inlet 221 and the third air outlet 212 in response to the air parameters detected by the air detection device 10.

[0099] In an illustrative embodiment, as shown, the third air outlet 212 is disposed on a second side wall (e.g., the right rear wall as shown) adjacent to a first side wall on which the joint 23 is disposed on the second housing 21. Figure 2 As shown, the third air outlet 212 is disposed on a second side wall (e.g., the right rear wall as shown) adjacent to a first side wall on which the joint 23 is disposed on the second housing 21. ​ As shown, the third air outlet 212 is disposed on a second side wall (e.g., the right rear wall as shown) adjacent to a first side wall on which the joint 23 is disposed on the second housing 21.

[0100] In an illustrative embodiment, the second air outlet 222 and the third air outlet 212 can be configured with respective valves (e.g., air volume regulating valves, gate valves, and electric regulating valves, etc.) or installable with openable and closable baffles on the second air outlet 222 or the third air outlet 212 to regulate the conduction and cutting off of the second air outlet 222 or the third air outlet 212. When the third air outlet 212 is in the first mode of cutting off, for example, the fan 24 is in a continuous running state, it can be considered that the air conditioning device is in an internal circulation mode, i.e., the air (air in the air exchange space) sucked in through the second air inlet 221 is finally discharged through the second air outlet 222, and some air parameters (e.g., air temperature, air humidity, and air quality, etc.) are adaptively adjusted in the process; when the third air outlet 212 is in the second mode of conduction, it can be considered that the air conditioning device is in an external circulation mode, i.e., the air (air in the air exchange space) sucked in through the second air inlet 221 is finally discharged through the third air outlet 212 to the exhaust space, and this working mode can be triggered when the air parameters (e.g., the concentration of a certain odor in the air) detected by the odor detection unit 13 exceed the preset threshold. It should be understood that the embodiments of the present application are not limited thereto.

[0101] For example, the air conditioning device further includes a third mode (i.e., a shutdown mode) in which the fan 24 is in a shutdown (or standby) state.
