DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides a dehumidifier 100 for reducing indoor air humidity. It can prevent the WIFI component 120 from being interfered by the circuit, ensure the accuracy of the WIFI component 120 receiving the remote control signal, and avoid the remote control function failure.

[0025] It should be noted that the dehumidifier 100 is placed indoors, and the dehumidifier 100 can absorb the indoor air and dehumidify it, and then discharge the dehumidified air into the room to achieve the dehumidification effect of the indoor air. Specifically, the dehumidifier 100 has a WIFI remote control function, and the user can remotely control the start and stop of the dehumidifier 100 or adjust the operating state of the dehumidifier 100 through a mobile phone, which is convenient and practical, and the user experience is good.

[0026] The dehumidifier 100 includes a volute 110, a WIFI component 120, a display box 130, a housing 140 and a cover plate 150. The volute 110 is installed in the housing 140, and the volute 110 is provided with an air outlet 111. The volute 110 is used to guide the outlet airflow and blow the outlet airflow from the air outlet 111 to the room. The display box 130 and the WIFI component 120 are arranged at intervals and are both installed on the volute 110. The display box 130 is electrically connected to the WIFI component 120. The display box 130 is used to display the operating parameters of the dehumidifier 100, and realize human-computer interaction by setting buttons. The WIFI component 120 is used to receive a remote control signal and transmit the remote control signal to the display box 130 to realize the remote control function of the dehumidifier 100. The cover plate 150 is covered on the housing 140 to shield and protect the components in the housing 140, thereby improving the aesthetics of the entire dehumidifier 100.

[0027] Specifically, a limiting structure 112 is provided outside the volute 110, and the WIFI component 120 cooperates with the limiting structure 112. The limiting structure 112 is used to limit the WIFI component 120 to fix the relative position of the WIFI component 120 and the volute 110, and prevent the WIFI component 120 from being separated from the volute 110. The display box 130 and the WIFI component 120 are arranged at intervals, and the WIFI component 120 is provided with a power line 121. The WIFI component 120 is connected to the display box 130 through the power line 121 to achieve electrical connection between the display box 130 and the WIFI component 120, so as to ensure the stability of signal transmission. In this way, since there is a certain distance between the display box 130 and the WIFI component 120, the circuit board of the display box 130 will not cause circuit interference to the operation of the WIFI component 120, so as to ensure the accuracy of the WIFI component 120 in receiving the remote control signal, avoid the situation that the WIFI component 120 cannot receive the remote control signal, thereby avoiding the situation that the remote control function fails, and improving the user experience.

[0028] It is worth noting that the dehumidifier 100 also includes a centrifugal fan (not shown), an evaporator 170, a condenser 180, a compressor 190 and a throttling device (not shown). The centrifugal fan is installed in the volute 110, and the centrifugal fan is used to generate negative pressure to drive air flow, thereby forming an outlet airflow. The evaporator 170, the condenser 180, the compressor 190 and the throttling device are all installed in the housing 140, the evaporator 170 and the condenser 180 are arranged at intervals, and the condenser 180 is arranged between the evaporator 170 and the volute 110. The centrifugal fan is used to drive the air to pass through the evaporator 170 and the condenser 180 in sequence, and flow to the room through the volute 110. In this process, the evaporator 170 and the condenser 180 work together to dehumidify the air passing through, so as to achieve the effect of dehumidification without affecting the indoor temperature.

[0029] Furthermore, the compressor 190, the condenser 180, the throttling device and the evaporator 170 are connected end to end and combined to form a refrigerant flow path for the refrigerant to flow. During the refrigerant flow, the compressor 190 is used to compress the refrigerant and transport the high-temperature and high-pressure gaseous refrigerant to the condenser 180; the condenser 180 is used to perform heat exchange on the refrigerant to cool the high-temperature and high-pressure gaseous refrigerant to a low-temperature and high-pressure liquid refrigerant and make it flow to the throttling device; the throttling device is used to throttle the refrigerant to change the low-temperature and high-pressure liquid refrigerant to a low-temperature and low-pressure liquid refrigerant and make it flow to the evaporator 170; the evaporator 170 is used to perform heat exchange on the refrigerant to change the low-temperature and low-pressure liquid refrigerant to a low-pressure gaseous refrigerant and make it flow back to the compressor 190. During this process, the centrifugal fan generates negative pressure to draw indoor air into the outer casing 140, and passes through the evaporator 170 and the condenser 180 in sequence to form an outlet airflow, and finally blows out through the outlet 111 of the volute 110 to achieve a dehumidification function.

[0030] Specifically, in the process of the outlet airflow passing through the evaporator 170, the low-temperature and low-pressure liquid refrigerant in the evaporator 170 absorbs the heat of the outlet airflow, so that the moisture in the outlet airflow condenses on the evaporator 170 and forms condensation. At this time, the outlet airflow cools down, and the low-temperature and low-pressure liquid refrigerant heats up to form a low-pressure gaseous refrigerant, thereby realizing the dehumidification function. In the process of the outlet airflow passing through the condenser 180, the outlet airflow absorbs the heat of the high-temperature and high-pressure gaseous refrigerant in the condenser 180. At this time, the outlet airflow heats up (restores to a temperature close to the indoor temperature), and the high-temperature and high-pressure gaseous refrigerant cools down to form a low-temperature and high-pressure liquid refrigerant. In this way, since the outlet airflow first cools down and then heats up in the process of passing through the evaporator 170 and the condenser 180 at one time, and finally reaches a level close to the indoor temperature, the outlet airflow blown out from the air outlet 111 will not have much impact on the indoor temperature, thereby improving the user experience.

[0031] Please refer to Figure 3 The WIFI component 120 includes a WIFI connector 122 and a WIFI module 123. The WIFI module 123 is plugged into the WIFI connector 122 to achieve a detachable connection between the WIFI connector 122 and the WIFI module 123, which is convenient for replacing or maintaining the WIFI module 123. Specifically, the WIFI connector 122 is provided with a power cord 121, and the WIFI connector 122 is connected to the display box 130 through the power cord 121 to achieve an electrical connection between the WIFI module 123 and the display box 130, which is convenient for signal transmission. The WIFI connector 122 and the WIFI module 123 both cooperate with the limiting structure 112, and the limiting structure 112 can limit the WIFI connector 122 and the WIFI module 123 at the same time to improve the limiting effect and ensure the stability of the installation of the WIFI connector 122 and the WIFI module 123.

In this embodiment, the dehumidifier 100 is arranged vertically, and the bearing block 1125 supports the WIFI connector 122 in the vertical direction.
