Example 1

As shown in fig. 1 to 4, an embodiment of the present invention provides an air purifier including: a housing 1, a semiconductor temperature adjusting device 2, a heat generating component 3, and a temperature detecting device 4.

Specifically, in the embodiment of the present invention, the housing 1 is provided with an air outlet 5, the semiconductor temperature adjusting device 2 is arranged in the housing 1, and the semiconductor temperature adjusting device 2 is located upstream of the air outlet 5 in an air outlet direction, that is, in an arrow direction in fig. 1, and the semiconductor temperature adjusting device 2 has a cooling and heating operation state. Therefore, when the semiconductor temperature control device 2 is in a cooling state and wind generated by the air cleaner enters the semiconductor temperature control device 2, the semiconductor temperature control device 2 cools the wind generated by the air cleaner and then discharges the cooled wind to the outside through the wind outlet 5. Similarly, when the semiconductor temperature control device 2 is in a heating state and wind generated by the air purifier enters the semiconductor temperature control device 2, the semiconductor temperature control device 2 heats the wind generated by the air purifier and then discharges the heated wind to the outside through the outlet 5.

Further, a heating component 3 is disposed in the housing 1, and the heating component 3 is located upstream of the semiconductor temperature adjusting device 2 in the air outlet direction. The heating component 3 is used for generating high temperature through heating, and plays a role in sterilization. A temperature sensing device 4 is disposed on the housing 1, the temperature sensing device 4 being in communication with the semiconductor temperature regulating device 2, which may include wireless and limited connections. The temperature detection device 4 is used for detecting the ambient temperature and changing the working state of the semiconductor temperature regulation device 2 based on the ambient temperature.

In the actual working process of the utility model, the environment temperature needs to be obtained by the temperature detection device 4, and then whether the environment temperature is within the preset temperature range is judged, wherein the preset temperature range is the temperature range when the user feels comfortable. The temperature range for human comfort may be between 18 ℃ and 25 ℃. Since the temperature detection device 4 is in communication connection with the semiconductor temperature adjustment device 2, when the ambient temperature is detected to be out of the preset temperature range by the temperature detection device 4, the operating state of the semiconductor temperature adjustment device 2 can be changed to control the ambient temperature to be in the preset temperature range.

Specifically, when the ambient temperature is higher than the preset temperature range, the operating state of the semiconductor temperature adjustment device 2 may be adjusted to be cooling until the ambient temperature is controlled within the preset temperature range, and then the semiconductor temperature adjustment device 2 may be controlled to stop operating. When the ambient temperature is lower than the preset temperature range, the operating state of the semiconductor temperature adjusting device 2 is adjusted to heating until the ambient temperature is controlled within the preset temperature range, and then the semiconductor temperature adjusting device 2 can be controlled to stop operating.

With the arrangement, the working state of the semiconductor temperature adjusting device 2 can be automatically changed according to the ambient temperature, and when the ambient temperature is higher than the suitable temperature range of a user, the semiconductor temperature adjusting device 2 is controlled to refrigerate, so that the ambient temperature can be reduced; when the ambient temperature is lower than the suitable temperature range of the user, the semiconductor temperature adjusting device 2 is controlled to heat, so that the ambient temperature can be increased, the ambient temperature is ensured to be in the suitable temperature range of the user, and the use experience of the user can be improved.

Further, in an optional embodiment of the present invention, the semiconductor temperature adjustment device 2 includes a semiconductor chilling plate, a switch module 7 and a power supply 6, which are connected in sequence. The temperature detection device 4 is connected with the switch module 7 in a communication way.

In the embodiment of the present invention, the switch module 7 may be a double-pole double-throw switch, two ends of the semiconductor cooling plate are connected to two movable ends of the switch module 7, and the power supply 6 is connected to two fixed ends of the switch module 7.

Therefore, the flow direction of the internal current of the semiconductor refrigerating sheet can be changed through the switch module 7, so that the semiconductor refrigerating sheet switches the refrigerating and heating working states. For example, as shown in fig. 2, when the cooling mode is turned on, the switching state of the switching module 7 is changed, so that the power supply 6 supplies a forward current to the semiconductor cooling plate, and the semiconductor cooling plate starts a cooling operation. As shown in fig. 3, when the heating mode is turned on, the switching state of the switching module 7 is changed, so that the power supply 6 supplies a reverse current to the semiconductor chilling plates, and the semiconductor chilling plates start heating operation.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Variations and modifications in other variations may occur to those skilled in the art based upon the foregoing description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the utility model.
