With reference to FIGS. 1 to 5, according to an embodiment of the present invention, a detection device is provided.

Specifically, as shown in FIG. 1, the detection device includes a housing 10 and a detection part 40. The housing 10 has an air inlet channel 11 and a detection channel 12. The air inlet channel 11 and the detection channel 12 are provided independently of each other, and the detection unit 40 Located in the detection channel 12, the detection unit 40 is used to detect the environmental working conditions of the external airflow in the detection channel 12.

In this embodiment, the air intake channel and the detection channel are separately provided in the housing, and the detection portion is provided in the detection channel, so that the detection portion is isolated from the heat exchange component in the housing, thereby making the detection portion It can accurately detect the temperature, humidity and other environmental working conditions of external airflow, such as formaldehyde content and pollution degree.

By providing a first air inlet 13 and a second air inlet 14 on the air outlet panel of the casing, the external airflow is introduced into the air inlet channel 11 and the detection channel 12 through the first air inlet 13 and the second air inlet 14, respectively, Therefore, the detection part in the detection channel 12 can accurately detect the temperature and humidity of the external airflow.

As shown in FIGS. 2 and 5, the detection unit 40 is located at the air inlet end of the detection channel 12. By setting the detection part 40 at the air inlet end of the detection channel 12, such a setting enables the detection part to be in direct contact with the external airflow as much as possible, avoiding the temperature change caused by the change in the depth of the detection channel 12, and improving the detection accuracy of the detection part 40 .

As shown in FIG. 5, a wind deflector 121 is provided at the air inlet end of the detection channel 12, and a limited flow opening 122 is opened on the wind shield 121, and the cross-sectional area of the flow restriction 122 is smaller than the cross-sectional area of the detection channel 12 . By installing a wind deflector 121 on the inlet end of the detection channel 12 and opening a restrictor 122 on the wind deflector 121, this setting limits the intake air flow of the detection channel 12 and prevents the opening of the detection channel 12 from being too large And there is a hidden danger of airflow backflow.

As shown in FIG. 3, an intake grille is provided at the first air inlet 13. This arrangement prevents foreign objects from entering the first air inlet.

Further, a plurality of air inlet holes are provided at the second air inlet 14, and the plurality of air inlet holes are arranged at intervals.

In this way, the fan unit 20 can efficiently perform the external air suction operation through the air inlet channel 11 and the detection channel 12 at the same time. Of course, the air inlet direction of the air inlet channel 11 and the air inlet direction of the detection channel 12 may also be set at an angle, in particular, the direction of the detection channel 12 and the air suction direction of the fan section 20 are set at an angle to separate the air inlet The air inlet direction of the channel 11 is set in the same direction as the air suction direction of the fan section 20, so that the installation can reduce the suction operation of the detection channel 12 to the external airflow and prevent the hidden danger of airflow backfill.

In this embodiment, the detection unit 40 further includes a temperature and humidity sensor, which is used to detect the temperature and humidity of the external airflow in the detection channel 12.

In this embodiment, an independent channel with a temperature and humidity sensor, that is, a detection channel 12 is provided in the detection device, which communicates with the air inlet channel 11 on the front side of the fan to form a small air circulation system without being affected by the evaporator The effect of cold and condensed water ensures accurate detection of the temperature and humidity of the environment.

The detection unit 40 is located in the detection channel 12. The fan unit 20 is installed in the installation area 15. The installation area 15 communicates with the outside through the air inlet channel 11 and the detection channel 12. The fan unit 20 passes through the inlet The wind channel 11 and the detection channel 12 introduce outside airflow into the housing 10, and the detection part 40 is used to detect the temperature and humidity of the outside airflow in the detection channel 12. The air inlet channel and the detection channel are separately provided in the housing, and the detection part is provided in the detection channel, so that the detection part is isolated from the heat exchange parts in the housing, so that the dehumidifier can accurately detect the external airflow Temperature, humidity and other environmental working conditions, such as formaldehyde content, pollution degree, etc. Conducive to improving the experience of using dehumidifiers.

As shown in FIG. 1, the installation area 15 includes a first installation area 151 and a second installation area 152, the fan section 20 is disposed in the first installation area 151, and the first end of the detection channel 12 communicates with the first installation area 151, The second end of the detection channel 12 communicates with the outside world. The second mounting area 152 is disposed adjacent to the first mounting area 151. The second mounting area 152 is used to mount the heat exchange portion 30. At least part of the second mounting area 152 is formed The air inlet channel 11 connecting the first installation region 151 and the outside world, and the detection channel 12 and the second installation region 152 are provided independently of each other. By setting the second installation area as an air inlet channel 11 independent of the detection channel 12, such a configuration is such that the detection part is isolated from the heat exchange parts in the housing, so that the detection part can accurately detect the temperature and humidity of the external airflow.

In this embodiment, the detection channel 12 is located on top of the second installation area 152. This arrangement makes the detection channel 12 easy to install, and the intake air of the detection channel 12 is isolated from the intake air of the second installation area 152, so that the detection part can accurately detect the temperature and humidity of the external airflow.

In this embodiment, when the fan system is in operation, the fan unit sucks in air from the outside environment, and most of the air passes through the inlet grille and the air inlet channel 11, flows through the evaporator and condenser, and is discharged back through the fan system Environment. A very small part of the airflow passes through the air inlet hole of the casing, flows through the temperature and humidity sensor, passes through the detection channel 12 and the fan system, and then is discharged back into the environment. Since the temperature and humidity sensor gas is located in the independent detection channel 12, the airflow passing through is also independent of the influence of the evaporator, and can accurately detect the temperature and humidity of the environment.
