Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a dehumidifier. Background Technology

[0002] Currently, with the continuous improvement of living standards, people have increasingly higher requirements for indoor air comfort. In humid areas or during seasons with continuous rain, indoor air humidity is high, and dehumidifiers are usually needed to dehumidify the indoor air to improve human comfort. To improve the functionality of dehumidifiers, many manufacturers have set up Wi-Fi remote control functions, allowing users to control the dehumidifier to start or stop remotely via their mobile phones, which is convenient and practical. However, in current dehumidifiers with remote control functions, the Wi-Fi module is integrated on the circuit board of the display box. The circuit board can cause circuit interference to the operation of the Wi-Fi module, affecting the accuracy of the Wi-Fi module in receiving remote control signals, and even causing the Wi-Fi module to fail to receive remote control signals, resulting in the failure of the remote control function and affecting the user experience. Summary of the Invention

[0003] The problem solved by this invention is how to prevent WIFI components from being interfered with by circuits, ensure the accuracy of WIFI components in receiving remote control signals, and avoid the failure of remote control function.

[0004] To solve the above problems, the technical solution of the present invention is implemented as follows:

[0005] This invention provides a dehumidifier, including a volute casing, a Wi-Fi component, and a display box. A limiting structure is provided outside the volute casing. The Wi-Fi component cooperates with the limiting structure, which limits the movement of the Wi-Fi component. The display box is spaced apart from the Wi-Fi component. The Wi-Fi component is equipped with a power cord connected to the display box. Compared with existing technologies, the dehumidifier provided by this invention, due to the use of a Wi-Fi component that cooperates with the limiting structure and is spaced apart from the display box, can prevent the Wi-Fi component from being affected by circuit interference, ensuring the accuracy of the Wi-Fi component in receiving remote control signals and avoiding remote control failure.

[0006] Furthermore, the WIFI component includes a WIFI connector and a WIFI module. The WIFI module is plugged into the WIFI connector, which is equipped with a power cord. Both the WIFI connector and the WIFI module cooperate with a limiting structure. The limiting structure can simultaneously limit the movement of both the WIFI connector and the WIFI module to improve the limiting effect and ensure the stability of the WIFI connector and WIFI module installation.

[0007] Furthermore, the limiting structure includes a first side plate, a second side plate, a first stop block, a second stop block, and a support block. The first and second side plates are arranged opposite each other in a first direction, and the WIFI connector is disposed between the first and second side plates. The first stop block, the second stop block, and the support block are all disposed between the first and second side plates. The first and second stop blocks are arranged opposite each other in a second direction, and the WIFI connector is disposed between the first and second stop blocks. The first direction is perpendicular to the second direction. The support block abuts against the lower end of the WIFI connector. The support block is used to support the WIFI connector to prevent it from dislodging downwards between the first and second stop blocks under gravity.

[0008] Furthermore, a first stop is disposed on the side of the second stop near the volute, the first stop is connected between the first side plate and the second side plate, the second stop is connected to the first side plate and / or the second side plate, and a bearing block is connected to the first side plate and / or the second side plate. This ensures the limiting effect on the WIFI connector while improving the strength of the first and second side plates and preventing deformation of the first and second side plates.

[0009] Furthermore, the WIFI connector includes a straight portion and a constricted portion connected to each other. The constricted portion is located below the straight portion, and the straight portion is fitted between the first side plate and the second side plate, and also fitted between the first stop block and the second stop block. The constricted portion has a constricted inclined surface, and the support block has a support inclined surface. The constricted inclined surface and the support inclined surface abut against each other. The support block can both support the constricted portion through the cooperation of the support inclined surface and the constricted inclined surface, and also limit the constricted portion through the cooperation of the support inclined surface and the constricted inclined surface, which is stable, reliable, and has a good limiting effect.

[0010] Furthermore, there are two constricted bevels and two bearing blocks. The two constricted bevels are located opposite each other on both sides of the constricted portion, and each constricted bevel abuts against the bearing bevel of a bearing block. A first stop block connects the two bearing blocks. This ensures the support and positioning of the WIFI connector while increasing the strength of the two bearing blocks and preventing deformation.

[0011] Furthermore, the limiting structure includes a first limiting block, a second limiting block, and a supporting block. The first and second limiting blocks are spaced apart, and the supporting block is connected between the first and second limiting blocks. The WIFI module is positioned between the first and second limiting blocks and abuts against the supporting block. This improves the strength of the first and second limiting blocks, prevents deformation of the first and second limiting blocks, and the supporting block limits the WIFI module to ensure that the WIFI module and the WIFI connector are located on the same vertical plane, facilitating the insertion or removal of the WIFI module.

[0012] Furthermore, a stop is provided at the end of the supporting block, which abuts against the top of the WIFI module. This limits the WIFI module in the vertical direction, preventing it from becoming loose and avoiding accidental upward detachment from the WIFI connector. This ensures the reliability of the connection between the WIFI module and the WIFI connector, thereby improving the stability of the dehumidifier's remote control function.

[0013] Furthermore, the volute is provided with a top wall and side walls adjacent to each other, a limiting structure is provided outside the side walls, and the top wall has an air outlet for air to be blown out. An extension plate extends along the plane of the top wall, and the display box is mounted on the extension plate. This achieves the spacing between the display box and the WIFI component, and facilitates the disassembly and assembly of the display box and the WIFI component.

[0014] Furthermore, the dehumidifier also includes a casing and a cover. The volute is installed inside the casing, and the cover is placed on the casing. The cover includes an interconnected grille section and a panel section. The grille section is located above the air outlet, and the panel section is located above the display box. The grille section is used to prevent external objects from entering the air outlet, improving safety. Users can operate the display box through the panel section to achieve human-computer interaction. Attached Figure Description

Detailed Implementation

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Please refer to the reference. Figure 1 and Figure 2 This invention provides a dehumidifier 100 for reducing indoor air humidity. It can prevent the WIFI component 120 from being interfered with by circuitry, ensuring the accuracy of the WIFI component 120 in receiving remote control signals and avoiding remote control function failure.

[0025] It should be noted that the dehumidifier 100 is placed indoors. It draws in indoor air, dehumidifies it, and then expels the dehumidified air back into the room, thus achieving a dehumidification effect. Specifically, the dehumidifier 100 has a Wi-Fi remote control function, allowing users to remotely control its start / stop and adjust its operating status via their mobile phones. This is convenient, practical, and provides a good user experience.

[0026] The dehumidifier 100 includes a volute 110, a Wi-Fi component 120, a display box 130, a housing 140, and a cover 150. The volute 110 is installed inside the housing 140 and has an air outlet 111. The volute 110 guides the airflow and directs it into the room. The display box 130 is spaced apart from the Wi-Fi component 120 and both are mounted on the volute 110. The display box 130 is electrically connected to the Wi-Fi component 120 and displays the operating parameters of the dehumidifier 100. It also provides human-machine interaction via buttons. The Wi-Fi component 120 receives remote control signals and transmits them to the display box 130 to enable remote control of the dehumidifier 100. The cover 150 covers the housing 140 to conceal and protect the components inside, improving the overall aesthetics of the dehumidifier 100.

[0027] Specifically, a limiting structure 112 is provided on the outside of the volute 110. 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, preventing the WIFI component 120 from detaching from the volute 110. The display box 130 is spaced apart from the WIFI component 120. The WIFI component 120 is provided with a power cable 121, which connects the WIFI component 120 to the display box 130 to achieve electrical connection between the display box 130 and the WIFI component 120, ensuring the stability of signal transmission. In this way, because 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, ensuring the accuracy of the WIFI component 120 in receiving remote control signals, avoiding the situation where the WIFI component 120 cannot receive remote control signals, thereby avoiding the failure of the remote control function 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 inside the volute 110 and is used to generate negative pressure to drive airflow, thereby forming an outlet airflow. The evaporator 170, condenser 180, compressor 190, and throttling device are all installed inside the outer casing 140. The evaporator 170 and condenser 180 are spaced apart, with the condenser 180 positioned between the evaporator 170 and the volute 110. The centrifugal fan drives air to pass sequentially through the evaporator 170 and condenser 180, and then through the volute 110 into the room. During this process, the evaporator 170 and condenser 180 work together to dehumidify the passing air, achieving dehumidification without affecting the indoor temperature.

[0029] Furthermore, the compressor 190, condenser 180, throttling device, and evaporator 170 are connected end-to-end and combined to form a refrigerant flow path for refrigerant flow. During the refrigerant flow process, the compressor 190 compresses the refrigerant and delivers the high-temperature, high-pressure gaseous refrigerant to the condenser 180; the condenser 180 exchanges heat with the refrigerant to cool the high-temperature, high-pressure gaseous refrigerant into a low-temperature, high-pressure liquid refrigerant, which then flows to the throttling device; the throttling device throttles the refrigerant to change the low-temperature, high-pressure liquid refrigerant into a low-temperature, low-pressure liquid refrigerant, which then flows to the evaporator 170; the evaporator 170 exchanges heat with the refrigerant to change the low-temperature, low-pressure liquid refrigerant into a low-pressure gaseous refrigerant, which then flows back to the compressor 190. During this process, the centrifugal fan generates negative pressure to draw indoor air into the outer casing 140, and then through the evaporator 170 and condenser 180 in sequence to form an airflow. Finally, the air is blown out through the air outlet 111 of the volute 110 to achieve the dehumidification function.

[0030] Specifically, as the airflow passes through the evaporator 170, the low-temperature, low-pressure liquid refrigerant in the evaporator 170 absorbs heat from the airflow, causing moisture in the airflow to condense on the evaporator 170 and form condensation. At this time, the airflow cools down, and the low-temperature, low-pressure liquid refrigerant heats up to form low-pressure gaseous refrigerant, thus achieving dehumidification. As the airflow passes through the condenser 180, it absorbs heat from the high-temperature, high-pressure gaseous refrigerant in the condenser 180. At this time, the airflow heats up (restoring its temperature to near the room temperature), and the high-temperature, high-pressure gaseous refrigerant cools down to form low-temperature, high-pressure liquid refrigerant. In this way, because the airflow cools down and then heats up as it passes through the evaporator 170 and condenser 180, finally reaching a temperature close to the room temperature, the airflow blown out from the air outlet 111 does not significantly affect the room temperature, 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, facilitating replacement or maintenance of the WIFI module 123. Specifically, the WIFI connector 122 is provided with a power cord 121, which connects the WIFI connector 122 to the display box 130, enabling electrical connection between the WIFI module 123 and the display box 130 for signal transmission. Both the WIFI connector 122 and the WIFI module 123 cooperate with a limiting structure 112, which simultaneously limits the movement of both the WIFI connector 122 and the WIFI module 123, improving the limiting effect and ensuring the stability of their installation.

[0032] Please refer to the reference. Figure 4 and Figure 5 The limiting structure 112 includes a first side plate 1121, a second side plate 1122, a first stop 1123, a second stop 1124, and a bearing block 1125. The first side plate 1121, the second side plate 1122, the first stop 1123, the second stop 1124, and the bearing block 1125 combine to form the first limiting structure, which is used to limit the WIFI connector 122. Specifically, the first side plate 1121 and the second side plate 1122 are arranged opposite to each other in a first direction, and the WIFI connector 122 is disposed between the first side plate 1121 and the second side plate 1122. The first side plate 1121 and the second side plate 1122 are used to limit the WIFI connector 122 in the first direction. The first stop 1123 and the second stop 1124 are both disposed between the first side plate 1121 and the second side plate 1122, and the first stop 1123 and the second stop 1124 are arranged opposite to each other in a second direction. The first stop 1123 and the second stop 1124 are positioned between the first stop 1123 and the second stop 1124 to limit the WIFI connector 122 in the second direction. The support block 1125 is positioned between the first side plate 1121 and the second side plate 1122. The support block 1125 abuts against the lower end of the WIFI connector 122 and supports the WIFI connector 122 to prevent the WIFI connector 122 from falling out between the first stop 1123 and the second stop 1124 under the action of gravity.

[0033] Specifically, the first direction is perpendicular to the second direction. The first side plate 1121, the second side plate 1122, the first stop block 1123, and the second stop block 1124 work together to restrict the four degrees of freedom of the WIFI connector 122, preventing the WIFI connector 122 from becoming loose, improving the limiting effect of the WIFI connector 122, and ensuring the stability of the WIFI connector 122 installation. In this embodiment, the dehumidifier 100 is vertically arranged, and the bearing block 1125 supports the WIFI connector 122 in the vertical direction. The first direction, the second direction, and the vertical direction are perpendicular to each other to further improve the limiting effect of the WIFI connector 122.

[0034] Furthermore, the first stop 1123 is disposed on the side of the second stop 1124 near the volute 110, that is, the first stop 1123 is disposed relatively close to the volute 110, and the second stop 1124 is disposed relatively away from the volute 110. Specifically, the first stop 1123 is connected between the first side plate 1121 and the second side plate 1122 to improve the strength of the first side plate 1121 and the second side plate 1122 while ensuring the limiting effect on the WIFI connector 122, and to prevent the first side plate 1121 and the second side plate 1122 from deforming. In this embodiment, the first stop 1123 is fitted to the outside of the volute 110, and the first stop 1123 acts as a reinforcing rib. The first side plate 1121, the first stop 1123 and the second side plate 1122 together form a U-shape to further improve the strength of the first side plate 1121 and the second side plate 1122.

[0035] It should be noted that the second stop 1124 is connected to the first side plate 1121 and / or the second side plate 1122, and the bearing block 1125 is connected to the first side plate 1121 and / or the second side plate 1122 to facilitate manufacturing. In this embodiment, the second stop 1124 is connected to the first side plate 1121 and extends towards the second side plate 1122 to stop and limit the WIFI connector 122; the bearing block 1125 is connected to both the first side plate 1121 and the second side plate 1122 to ensure the support effect for the WIFI connector 122. However, this is not the only option. In other embodiments, the second stop 1124 may be connected only to the second side plate 1122, or it may be connected between the first side plate 1121 and the second side plate 1122; the bearing block 1125 may be connected only to the first side plate 1121, or it may be connected only to the second side plate 1122; the specific positions of the second stop 1124 and the bearing block 1125 are not limited.

[0036] The WIFI connector 122 includes a straight portion 124 and a tapered portion 125 connected to each other. The straight portion 124 and the tapered portion 125 are integrally formed to improve the connection strength. The tapered portion 125 is located below the straight portion 124, and the tapered portion 125 gradually narrows from top to bottom. The WIFI module 123 is inserted into the top of the straight portion 124, and a power cord 121 is provided at the bottom of the tapered portion 125. Specifically, the straight portion 124 is fitted between the first side plate 1121 and the second side plate 1122, and is also fitted between the first stop 1123 and the second stop 1124. The first side plate 1121 and the second side plate 1122 limit the straight portion 124 in a first direction, and the first stop 1123 and the second stop 1124 limit the straight portion 124 in a second direction. In this embodiment, the constricted portion 125 is provided with a constricted inclined surface 126, and the bearing block 1125 is provided with a bearing inclined surface 1126. The constricted inclined surface 126 and the bearing inclined surface 1126 abut against each other. The bearing block 1125 can support the constricted portion 125 through the cooperation of the bearing inclined surface 1126 and the constricted inclined surface 126, and can also limit the constricted portion 125 through the cooperation of the bearing inclined surface 1126 and the constricted inclined surface 126. It is stable, reliable, and has a good limiting effect.

[0037] Specifically, there are two constricted inclined surfaces 126 and two supporting blocks 1125. The two constricted inclined surfaces 126 are located on opposite sides of the constricted portion 125. Each supporting block 1125 has one supporting inclined surface 1126. Each constricted inclined surface 126 abuts against the supporting inclined surface 1126 of one supporting block 1125. The two supporting inclined surfaces 1126 work together to simultaneously support and limit the two constricted inclined surfaces 126, thereby improving the limiting effect on the constricted portion 125. The first stop block 1123 is connected between the two supporting blocks 1125 to improve the strength of the two supporting blocks 1125 while ensuring the supporting and limiting effect on the WIFI connector 122, and to prevent the two supporting blocks 1125 from deforming.

[0038] In this embodiment, there are four support blocks 1125, which are divided into two groups. The two groups of support blocks 1125 are arranged at intervals in the vertical direction. Both groups of support blocks 1125 are used to support and limit the WIFI connector 122, so as to further improve the limiting effect on the constricted portion 125. Specifically, there are three first stops 1123, wherein the first first stop 1123 is connected between the first group of support blocks 1125, the second first stop 1123 is connected between the second group of support blocks 1125, and the third first stop 1123 is connected between the first side plate 1121 and the second side plate 1122.

[0039] The limiting structure 112 also includes a first limiting block 1127, a second limiting block 1128, and a supporting block 1129. The first limiting block 1127, the second limiting block 1128, and the supporting block 1129 are combined to form a second limiting structure, which is used to limit the WIFI module 123. The first limiting block 1127 and the second limiting block 1128 are spaced apart, and the WIFI module 123 is disposed between the first limiting block 1127 and the second limiting block 1128. The first limiting block 1127 and the second limiting block 1128 are used to limit the WIFI module 123. The abutment block 1129 is connected between the first limiting block 1127 and the second limiting block 1128. The abutment block 1129 is attached to the outside of the volute 110 to improve the strength of the first limiting block 1127 and the second limiting block 1128 and prevent the first limiting block 1127 and the second limiting block 1128 from deforming. The WIFI module 123 abuts against the abutment block 1129, and the abutment block 1129 can limit the WIFI module 123 to ensure that the WIFI module 123 and the WIFI connector 122 are located on the same vertical plane, which facilitates the insertion or removal of the WIFI module 123.

[0040] In this embodiment, a stop portion 1130 is provided at the end of the supporting block 1129. The stop portion 1130 is disposed at the top of the supporting block 1129 and abuts against the top of the WIFI module 123 to limit the WIFI module 123 in the vertical direction, prevent the WIFI module 123 from becoming loose, prevent the WIFI module 123 from accidentally disengaging from the WIFI connector 122, ensure the reliability of the connection between the WIFI module 123 and the WIFI connector 122, and thereby improve the stability of the remote control function of the dehumidifier 100.

[0041] Please refer to Figure 6 It is worth noting that the volute 110 is provided with a top wall 114 and a side wall 115 adjacent to each other. The limiting structure 112 is provided outside the side wall 115, and the WIFI component 120 is fixed outside the side wall 115 by cooperating with the limiting structure 112. The top wall 114 has an air outlet 111 for air to be blown out. After dehumidification, the air is guided by the volute 110 and blown upward into the room through the air outlet 111 to avoid the air blowing directly on people. Specifically, the top wall 114 has an extension plate 116 extending along its plane. The display box 130 is installed on the extension plate 116 to achieve the spacing between the display box 130 and the WIFI component 120, and to facilitate the disassembly and assembly of the display box 130 and the WIFI component 120.

[0042] In this embodiment, the cover plate 150 includes a grille portion 151 and a panel portion 152 connected to each other. The grille portion 151 is disposed above the air outlet 111, allowing air blown out of the air outlet 111 to be blown upwards through the grille portion 151 without affecting the airflow. The grille portion 151 is used to prevent external objects from entering the air outlet 111, thus improving safety. The panel portion 152 is disposed above the display box 130, allowing the user to operate the display box 130 through the panel portion 152 to achieve human-computer interaction.

[0043] The dehumidifier 100 of this embodiment of the invention has a limiting structure 112 outside the volute 110. A WIFI component 120 cooperates with the limiting structure 112, which limits the WIFI component 120. A display box 130 is spaced apart from the WIFI component 120. The WIFI component 120 is equipped with a power cord 121 connected to the display box 130. Compared with the prior art, the dehumidifier 100 provided by this invention, due to the use of a WIFI component 120 that cooperates with the limiting structure 112 and is spaced apart from the display box 130, can prevent the WIFI component 120 from being interfered with by circuits, ensure the accuracy of the remote control signal received by the WIFI component 120, and avoid the failure of the remote control function.

[0044] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
