In order to shorten the distance between the negative ion generator and the emitter head as much as possible while ensuring that the emitter head is arranged close to the air outlet, thereby shortening the length of the conductive wire, saving material costs, and facilitating the routing of the conductive wire to prevent the conductive wire from falling into the air inlet.

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 Figures 1 to 6 The embodiment of the present invention provides a dehumidifier 100 for reducing indoor air humidity. It can improve the concentration of negative ions while ensuring the air outlet effect, and increase the emission range of negative ions, thereby enhancing the air purification effect and improving the user experience.

[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, in the process of the dehumidifier 100 discharging the dehumidified air into the room, the dehumidifier 100 emits negative ions into the air, and the flowing air brings the negative ions into the room. The negatively charged negative ions and the positively charged dust floating in the indoor air are electrode-neutralized to make the dust naturally deposited, thereby achieving the air purification function.

[0026] The dehumidifier 100 includes a centrifugal fan wheel 110, a volute 120, a negative ion module 130, an electric control box 140, a conductive wire 150, a housing 160, an evaporator 170, a condenser 180 and a drive motor 200. The volute 120 has an air outlet 121, the drive motor 200 is connected to the centrifugal fan wheel 110, the drive motor 200 is used to drive the centrifugal fan wheel 110 to rotate, the centrifugal fan wheel 110 is installed in the volute 120, the centrifugal fan wheel 110 is used to drive air to blow out from the air outlet 121 to form an outlet air flow, and the volute 120 is used to guide the outlet air flow generated by the centrifugal fan wheel 110. The negative ion module 130 is installed outside the volute 120 to avoid interference with the operation of the centrifugal fan wheel 110 and to prevent blocking of the outlet air flow. Specifically, the negative ion module 130 is provided with a transmitter head 131, which partially extends into the volute 120, and the transmitter head 131 is located on the side of the volute 120 close to the air outlet 121. The transmitter head 131 is used to emit negative ions into the volute 120, so that the airflow blown out from the air outlet 121 carries negative ions, and these negative ions float to various places in the room under the action of the airflow, so as to achieve the air purification function. In this way, since the negative ion module 130 is generally installed outside the volute 120, only part of the transmitter head 131 extends into the volute 120, the negative ion module 130 will not affect the airflow, and the transmitter head 131 is arranged on the side of the volute 120 close to the air outlet 121, and the negative ions emitted by it can flow to the room with the airflow to the greatest extent. Therefore, the dehumidifier 100 increases the concentration of negative ions as much as possible while ensuring the air outlet effect, and increases the range of negative ion emission, thereby enhancing the air purification effect and improving the user experience.

[0027] It should be noted that the volute 120, the evaporator 170, the condenser 180 and the electric control box 140 are all installed in the housing 160, the evaporator 170 and the condenser 180 are arranged at intervals, and the condenser 180 is arranged between the evaporator 170 and the volute 120, and the centrifugal wind wheel 110 is used to drive the air to pass through the evaporator 170 and the condenser 180 in sequence, and enter the volute 120. 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. Further, the electric control box 140 is connected to the negative ion module 130 through the conductive wire 150, and the electric control box 140 is used to supply power to the negative ion module 130 through the conductive wire 150 and control the start and stop of the negative ion module 130, so as to stably and reliably realize the negative ion function of the dehumidifier 100.

[0028] The dehumidifier 100 further includes a compressor 190 and a throttling device (not shown). 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 wheel 110 generates negative pressure to draw indoor air into the outer casing 160, and pass through the evaporator 170 and the condenser 180 in sequence to form an outlet airflow, and finally blow out through the outlet 121 of the volute 120 to achieve a dehumidification function.

[0029] Specifically, when the outlet airflow passes 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 achieving a dehumidification function. When the outlet airflow passes 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 room temperature), and the high-temperature and high-pressure gaseous refrigerant cools down to form a low-temperature and high-pressure liquid refrigerant.

[0030] Furthermore, since the outlet airflow first cools down and then heats up in the process of passing through the evaporator 170 and the condenser 180, and finally reaches a temperature close to the indoor temperature, the outlet airflow blown out from the air outlet 121 will not have much impact on the indoor temperature, thereby improving the user experience. In addition, since the outlet airflow first flows through the evaporator 170 and the condenser 180, and then blows through the emitter 131, it is possible to prevent negative ions from passing through the evaporator 170 and the condenser 180 along with the outlet airflow, thereby preventing the negative ions from being lost under the action of the evaporator 170 and the condenser 180, thereby ensuring the air purification effect.

[0031] The negative ion module 130 includes a negative ion generator 132, which is electrically connected to a transmitter head 131. The negative ion generator 132 is spaced apart from the transmitter head 131, and both are connected to the volute 120, which is used to support and fix the negative ion generator 132 and the transmitter head 131. Specifically, the transmitter head 131 is a release tip made of metal or carbon elements. During the operation of the negative ion module 130, the negative ion generator 132 is processed by an EMI processing circuit and a lightning protection circuit to obtain a DC negative high voltage, and the DC negative high voltage is transmitted to the transmitter head 131 to generate a high corona. In this process, the transmitter head 131 emits a large number of electrons at a high speed, and these electrons are captured by oxygen molecules in the air, thereby generating air negative ions, so as to realize the function of the transmitter head 131 to emit negative ions.

[0032] Specifically, the electric control box 140 is connected to the emitter head 131 through the conductive wire 150, and the negative ion generator 132 is connected to the conductive wire 150 and is located on the wiring path of the conductive wire 150. The electric control box 140 is used to simultaneously supply power to the negative ion generator 132 and the emitter head 131 through the conductive wire 150. Since the negative ion generator 132 is arranged on the wiring path of the conductive wire 150, there is no need to add additional branch wires, which can effectively shorten the wiring length of the conductive wire 150 and reduce material costs.

[0033] In this embodiment, the volute 120 is provided with a first wire clamping groove 122 and a second wire clamping groove 123. The first wire clamping groove 122 is arranged between the electric control box 140 and the negative ion generator 132, and the second wire clamping groove 123 is arranged between the negative ion generator 132 and the transmitting head 131. The conductive wire 150 cooperates with the first wire clamping groove 122 and the second wire clamping groove 123 at the same time. The first wire clamping groove 122 and the second wire clamping groove 123 work together to limit the conductive wire 150, thereby defining the routing path of the conductive wire 150, preventing the conductive wire 150 from scattering, and thereby avoiding the conductive wire 150 from interfering with other components.

[0034] It is worth noting that the volute 120 is adjacently provided with an air inlet side wall 124 and an air outlet top wall 125, and the volute 120 includes a first shell 127 and a second shell 128, the first shell 127 and the second shell 128 are snap-fitted, the air inlet side wall 124 is provided on the first shell 127, and the air outlet top wall 125 is provided on the second shell 128. The air inlet side wall 124 is provided with an air inlet 126, and the air outlet 121 is provided on the air outlet top wall 125. Under the action of the centrifugal wind wheel 110, the air outlet airflow passing through the evaporator 170 and the condenser 180 flows into the volute 120 from the air inlet 126 of the air inlet side wall 124, and is blown upward from the air outlet 121 of the air outlet top wall 125. Specifically, the negative ion generator 132 and the emitter head 131 are both connected to the air inlet side wall 124, wherein the negative ion generator 132 is connected to the outside of the air inlet side wall 124, and the emitter head 131 is arranged through the air inlet side wall 124. The negative ion generator 132 and the emitter head 131 are relatively arranged on both sides of the air inlet 126, and are both located at one end of the air inlet side wall 124 close to the air outlet top wall 125, so as to shorten the distance between the negative ion generator 132 and the emitter head 131 as much as possible while ensuring that the emitter head 131 is arranged close to the air outlet 121, thereby shortening the length of the conductive wire 150, saving material costs, and facilitating the routing of the conductive wire 150 to prevent the conductive wire 150 from falling into the air inlet 126.

[0035] In this embodiment, the air inlet side wall 124 is provided with a screw column 1241, the negative ion generator 132 is convexly provided with a mounting platform 133, the mounting platform 133 is provided with a through hole 134, the mounting platform 133 is abutted against the screw column 1241, and the screw column 1241 is used to cooperate with the screw thread passing through the through hole 134 to fix the relative position of the mounting platform 133 and the screw column 1241, thereby fixing the relative position of the negative ion generator 132 and the air inlet side wall 124, and preventing the negative ion generator 132 from detaching from the air inlet side wall 124. Specifically, the position of the through hole 134 corresponds to the position of the screw column 1241, the screw passes through the through hole 134, and is tightened relative to the screw column 1241 to fasten the mounting platform 133 to the screw column 1241, thereby fixing the relative position of the negative ion generator 132 and the screw column 1241.

[0036] Furthermore, a boss 1242 is convexly provided on the air inlet side wall 124, and a screw column 1241 is provided on the boss 1242. The boss 1242 is used to raise the screw column 1241 to prevent the negative ion generator 132 from interfering with other components on the volute 120 during installation, thereby ensuring the installation effect. In this embodiment, a plurality of reinforcing ribs 1243 are provided on the outside of the screw column 1241, and the plurality of reinforcing ribs 1243 are connected to the outside of the screw column 1241 in an annular array and are all connected to the boss 1242. The plurality of reinforcing ribs 1243 work together to improve the connection strength between the screw column 1241 and the boss 1242, thereby preventing the screw column 1241 from bending or breaking.

[0037] It should be noted that the air inlet side wall 124 is provided with a mounting hole 1244, and the transmitter head 131 is provided with abutting platforms 135 and spring buckles 136 at intervals. The transmitter head 131 is partially arranged through the mounting hole 1244, and the inner side wall of the mounting hole 1244 is used to limit the transmitter head 131 to prevent the transmitter head 131 from loosening relative to the mounting hole 1244. The air inlet side wall 124 is clamped between the abutting platform 135 and the spring buckle 136, and the abutting platform 135 and the spring buckle 136 work together to fix the relative position of the transmitter head 131 and the air inlet side wall 124, prevent the transmitter head 131 from being displaced relative to the air inlet side wall 124, and avoid the transmitter head 131 from being separated from the air inlet side wall 124.

[0038] Specifically, the spring buckle 136 is elastic. During the installation of the transmitter head 131, the end of the transmitter head 131 close to the spring buckle 136 is first inserted into the mounting hole 1244 from the outside of the air inlet side wall 124. During this process, the inner wall of the mounting hole 1244 generates pressure on the spring buckle 136 to overcome the elastic force of the spring buckle 136 and cause the spring buckle 136 to undergo elastic deformation; when the spring buckle 136 is fully extended out of the mounting hole 1244, the abutment platform 135 just abuts against the air inlet side wall 124. At this time, the inner wall of the mounting hole 1244 no longer applies pressure to the spring buckle 136, and the spring buckle 136 rebounds and resets under the action of its own elastic force, so that the air inlet side wall 124 is clamped between the abutment platform 135 and the spring buckle 136, thereby fixing the relative position of the transmitter head 131 and the air inlet side wall 124.

[0039] Further, the spring buckle 136 is obliquely arranged on the circumferential surface of the launch head 131, and the spring buckle 136 gradually moves away from the launch head 131 in the extension direction of the launch head 131 and in the direction close to the abutment platform 135. The spring buckle 136 can be elastically deformed in the direction close to the launch head 131 under the pressure of the inner wall of the mounting hole 1244. Specifically, a preset angle is formed between the spring buckle 136 and the extension direction of the launch head 131, and the preset angle ranges from 20 degrees to 45 degrees. A reasonable preset angle can ensure that the spring buckle 136 has a sufficient deformation amount to firmly clamp the air inlet side wall 124 between the spring buckle 136 and the abutment platform 135. In this embodiment, the preset angle is 30 degrees, but it is not limited thereto. In other embodiments, the preset angle can be 20 degrees or 45 degrees, and the size of the preset angle is not specifically limited.

[0040] In this embodiment, the number of the supporting platforms 135 and the spring buckles 136 are both two. The two supporting platforms 135 are relatively arranged on both sides of the launch head 131 in the first direction, and the two spring buckles 136 are relatively arranged on both sides of the launch head 131 in the second direction. The first direction is perpendicular to the second direction, that is, the two supporting platforms 135 and the two spring buckles 136 are respectively arranged around the launch head 131, so that the four sides of the launch head 131 can be effectively limited to prevent the launch head 131 from tilting or deflecting, improve the installation stability of the launch head 131, and prevent the launch head 131 from detaching from the air inlet side wall 124.

Compared with the prior art, the dehumidifier 100 provided by the present invention adopts the negative ion module 130 installed outside the volute 120 and the transmitter 131 extending into the volute 120 and arranged close to the air outlet 121, so that the concentration of the emission of negative ions can be increased while ensuring the air outlet effect, and the emission range of negative ions can be increased, thereby enhancing the air purification effect and improving the user experience.

[0042] Although the present invention is disclosed as above, the present invention is not limited thereto.
