Description

Technical Field

[0001] The utility model relates to the field of tower fans, in particular to a tower fan. Background Art

[0002] Tower fans form a three-dimensional exchange system between indoor and outdoor air based on the principle of airflow. Tower fans usually "throw" the wind out through a crossflow fan to form an airflow, that is, the wind pressure is generated by the rotation of the wind wheel to generate centrifugal wind force, and finally the wind force is transmitted out through the internal wind guide wall. Since the crossflow wind wheel is generally cylindrical, the use of a tower fan obtains a three-dimensional airflow wall or wind curtain, which is perpendicular to the ground and swings left and right to blow. The crossflow wind wheel has many blades, and the air supply is uniform and soft, very close to natural wind, making people feel comfortable.

[0003] At present, for tower fans on the market, in order to effectively utilize the internal space of the tower fan, the functional components such as the drive device and humidifier of the tower fan are usually hidden between the wind duct and the base of the tower fan. Therefore, the wiring harness used to electrically connect the various functional components in the tower fan is also arranged between the wind duct and the base together with the functional components. However, since tower fans are usually powered by an external power supply, which is usually 220V AC, and the functional components inside the tower fan usually use low-voltage DC, there will be wiring harnesses carrying high-voltage AC and wiring harnesses carrying low-voltage DC in the tower fan. In a small space, the high-voltage and low-voltage wiring harnesses are prone to interference, posing a safety hazard. Utility Model Content

[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] At present, for tower fans on the market, in order to effectively utilize the internal space of the tower fan, the functional components such as the drive device and humidifier of the tower fan are usually hidden between the wind duct and the base of the tower fan. Therefore, the wiring harness used to electrically connect the various functional components in the tower fan is also arranged between the wind duct and the base together with the functional components. However, since tower fans are usually powered by an external power supply, which is usually 220V AC, and the functional components inside the tower fan usually use low-voltage DC, there will be wiring harnesses carrying high-voltage AC and wiring harnesses carrying low-voltage DC in the tower fan. In a small space, the high-voltage and low-voltage wiring harnesses are prone to interference, posing a safety hazard.

[0044] Reference below Figure 1-Figure 11 A tower fan according to an embodiment of the present invention is described.

[0045] According to the utility model, the tower fan 1 includes a base 11, an air outlet 12, a functional module 13, a controller 141 and an adapter 142, wherein an installation cavity is formed in the base 11; the air outlet 12 is arranged at the top of the base 11, and an air duct is formed in the air outlet 12; the functional module 13 is arranged in the base 11 and is used to control the air flow velocity in the air duct in the air outlet 12, the direction of the air outlet 12 and / or the humidity in the air duct; the controller 141 is accommodated in the installation cavity and a low-voltage interface suitable for connecting to the functional module 13 is arranged on the controller 141; the adapter 142 is accommodated in the installation cavity and the adapter 142 has a high-voltage interface connected to an external power supply; wherein the low-voltage interface is arranged on the side of the controller 141 away from the adapter 142, and the high-voltage interface is arranged on the side of the adapter 142 away from the controller 141.

[0046] Specifically, Figure 3-Figure 6As shown, the base 11 constitutes the lower half structure of the tower fan 1, and an installation cavity is formed in the base 11, which can be used to assemble the functional module 13 of the tower fan 1. The air outlet 12 is arranged on the top of the base 11 to constitute the upper half structure of the tower fan 1, and an air duct is formed in the air outlet 12, which can transport the wind generated by the functional module 13 to the outside to realize the air outlet function of the tower fan 1. The base 11 and the air outlet 12 cooperate with each other to form the basic frame of the tower fan 1. The functional module 13 is a component inside the tower fan 1 for controlling the operation of the tower fan 1 and realizing various functions. For example, the functional module 13 for controlling the wind direction can adjust the air outlet direction of the tower fan 1 by controlling the rotation of the air outlet 12 and the base 11; the functional module 13 for controlling the wind speed can control the air outlet speed of the tower fan 1 by controlling the rotation speed of the wind source structure such as the wind wheel or fan in the air outlet 12; the functional module 13 for controlling the humidity of the air outlet can generate water mist and transport the water mist to the air duct to blow it out together with the wind to realize the function of the tower fan 1 to blow cold air and humidify the air.

[0047] In addition, the tower fan 1 is also provided with a controller 141 and an adapter 142, which are respectively arranged in the installation cavity of the tower fan 1. The adapter 142 is provided with a high-voltage interface connected to an external power supply. The tower fan 1 can connect the adapter 142 to an external power supply through a wiring harness carrying a high-voltage current so as to provide power for the operation of the tower fan 1; the controller 141 is provided with a low-voltage interface, and the tower fan 1 can be provided with a wiring harness carrying a low-voltage current to electrically connect the functional module 13 to the controller 141 so as to facilitate the controller 141 to control the operation of the functional module 13. The controller 141 and the adapter 142 can be directly electrically connected. When working, the external power supply transmits the high-voltage current to the adapter 142 through the wiring harness, and the adapter 142 can convert the high-voltage current into a low-voltage current and transmit it to the controller 141 through the wiring harness. The controller 141 can transmit the low-voltage current to the corresponding functional module 13 according to the real-time situation to realize the functions of the tower fan 1, such as air outlet, steering and humidification.

[0048] It is worth noting that the low-voltage interface is arranged on the side of the controller 141 away from the adapter 142, and the high-voltage interface is arranged on the side of the adapter 142 away from the controller 141. It can be understood that the high-voltage interface and the low-voltage interface are electrically connected to their respective corresponding structures in directions away from each other. When the low-voltage interface is electrically connected to the functional module 13 and the high-voltage interface is electrically connected to the external power supply, the wiring harness carrying the high-voltage current and the wiring harness carrying the low-voltage current are separated from each other and do not affect each other. The position arrangement scheme of the low-voltage interface and the high-voltage interface allows the wiring harness carrying the low-voltage current and the wiring harness carrying the high-voltage current to be separated from each other and do not interfere with each other when they are arranged inside the tower fan 1, avoiding the safety hazard caused by the wiring harness carrying the high-voltage current and the wiring harness carrying the low-voltage current contacting each other during the operation of the tower fan 1, thereby improving the safety of the tower fan 1.

[0049] According to the tower fan 1 of the utility model, the high-voltage AC power of the external power source is converted into low-voltage DC power through the adapter 142 and transmitted to the controller 141. The controller 141 can selectively conduct the electrical connection between each functional module 13 according to the functional mode of the tower fan 1 to control the operation of each functional module 13 and thus realize different functions of the tower fan 1. When the tower fan 1 is working, the tower fan 1 arranges the high-voltage interface and the low-voltage interface at positions away from each other to ensure that the wire harness carrying the high-voltage current and the wire harness carrying the low-voltage current will not interfere with each other, thereby improving the safety of the tower fan 1.

[0050] According to one embodiment of the utility model, the tower fan 1 also includes a mounting plate 143 and a power cord 151, the mounting plate 143 is connected to the base 11 and is arranged in the mounting cavity and extends in the height direction, the adapter 142 and / or the controller 141 is arranged on one side of the mounting plate 143; one end of the power cord 151 is connected to an external power supply, at least a portion of the power cord 151 extends on the other side of the mounting plate 143 and the other end of the power cord 151 is connected to the high-voltage interface of the adapter 142.

[0051] Specifically, the tower fan 1 is also provided with a mounting plate 143 and a power line 151, the mounting plate 143 is connected to the base 11 and arranged in the mounting cavity, and the mounting plate 143 extends in the height direction of the mounting cavity to provide an installation position for some functional modules 13 or various structures of the tower fan 1, for example, Figure 3 , Figure 8 and Fig. 9 As shown, during assembly, the adapter 142 and the controller 141 can be assembled on the same side of the mounting plate 143, and the adapter 142 is arranged between the controller 141 and the mounting plate 143. At this time, the low-voltage interface is located on the side of the controller 141 away from the mounting plate 143, and the high-voltage interface is located on the side of the adapter 142 facing the mounting plate 143. The positions of the adapter 142 and the controller 141 are arranged to reduce the distance between the controller 141 and the adapter 142 while ensuring that the high-pressure interface and the low-pressure interface are away from each other, thereby improving the compactness of the structure of the tower fan 1 while ensuring safety.

[0052] The power cord 151 is a wiring harness that connects an external power source to a high-voltage interface. One end of the power cord 151 is connected to an external power source, and the other end is connected to a high-voltage interface. At least a portion of the power cord 151 extends on the other side of the mounting plate 143. During assembly, at least a portion of the power cord 151 is disposed on the other side of the mounting plate 143. One end of the power cord 151 passes over the mounting plate 143 from the other side of the mounting plate 143 and is connected to the adapter 142 located on one side of the mounting plate 143. The arrangement position of the power cord 151 allows a sufficient gap to be reserved between the power cord 151 and the controller 141, thereby avoiding interference between the power cord 151 and the controller 141 or a wiring harness carrying a low-voltage current, thereby improving the safety of the tower fan 1.

[0053] According to one embodiment of the utility model, the base portion 11 includes a bottom plate 111, a support portion 112 and a top plate 113, and a through hole suitable for the power cord 151 to pass through is formed on the bottom plate 111; the support portion 112 is constructed into two and is respectively arranged on both sides of the bottom plate 111 in the width direction and extends in the height direction; the top plate 113 is arranged on the top of the support portion 112 and is connected to the air outlet portion 12; wherein, the mounting plate 143 is arranged between the two support portions 112 and the mounting plate 143 and the bottom plate 111 are spaced apart to form a mounting hole suitable for the functional module 13 and / or the power cord 151 to pass through.

[0054] Since the base 11 is equipped with various functional modules 13 and other structures of the tower fan 1, the structure of the base 11 will affect the overall structural assembly of the tower fan 1. Specifically, the base 11 is provided with a bottom plate 111, a support portion 112 and a top plate 113, one end of the support portion 112 is connected to the bottom plate 111, and the other end of the support portion 112 is connected to the top plate 113, and the bottom plate 111, the support portion 112 and the top plate 113 cooperate with each other to form a basic frame of the base 11. A via hole can be set on the base plate 111, and the position of the via hole can be arranged in the direction of the base plate 111 toward the other side of the mounting plate 143. During assembly, the power cord 151 can extend from the bottom of the base plate 111 to the inside of the base plate 111 and pass through the via hole to connect with the adapter 142. The setting of the via hole enables the part of the power cord 151 passing through the via hole to extend in the height direction of the other side of the mounting plate 143. When it extends to the same height as the adapter 142, it turns to the adapter 142 and extends to the high-voltage interface. The setting of the via hole facilitates the arrangement of the power cord 151.

[0055] The support portion 112 is constructed as two portions arranged on both sides of the bottom plate 111 in the width direction and extending in the height direction. The top of the support portion 112 is connected to the top plate 113. The top plate 113 can be used to connect to the air outlet 12. The support portion 112 can be used to support the top plate 113, thereby improving the ability of the top plate 113 to carry the air outlet 12, and thus improving the structural stability of the tower fan 1. A mounting plate 143 can be arranged between the two support portions 112. The mounting plate 143 can be spaced apart from the bottom plate 111 to define a mounting hole. The mounting hole can accommodate a portion of the functional module 13. During assembly, at least a portion of the functional modules 13 cooperate with each other and are accommodated in the mounting hole. The power cord 151 located on the other side of the mounting plate 143 can pass through the mounting hole at a position close to the adapter 142 and then return to one side of the mounting plate 143 and connect to the high-voltage interface of the adapter 142. The arrangement position of the mounting plate 143 can plan an assembly area for a part of the functional module 13, so that the functional modules 13 and various structures in the tower fan 1 are arranged more neatly and compactly, and it is also convenient to arrange the power cord 151 so that the power cord 151 can normally transmit high voltage current to the adapter 142.

[0056] According to an embodiment of the utility model, the base part 11 also includes a shell 114, which cooperates with the support part 112 and is arranged on the periphery of the support part 112 to define an installation cavity. Specifically, the base part 11 is also provided with a shell 114, which can cooperate with the support part 112. When assembled, the two ends of the shell 114 are respectively covered on the periphery of the bottom plate 111 and the top plate 113. When the shell 114 cooperates with the top plate 113, the bottom plate 111 and the support part 112, the installation cavity can be defined together. The shell 114 can improve the connection strength between the top plate 113 and the bottom plate 111, and at the same time, it can protect the functional module 13 and the power line 151 and other structures in the tower fan 1 from being affected by the external environment, thereby improving the safety of the tower fan 1.

[0057] According to an embodiment of the present invention, the adapter 142 and the controller 141 are arranged on the same side of the mounting plate 143, and the tower fan 1 further comprises an adapter housing 16, which is arranged on one side of the mounting plate 143 and has an adapter mounting cavity formed therein suitable for accommodating the adapter 142, and the controller 141 is connected to the side of the adapter housing 16 away from the mounting plate 143. Since the adapter 142 and the controller 141 are assembled on the same side of the mounting plate 143, the assembly of the adapter 142 and the controller 141 will affect the use of the adapter 142 and the controller 141. Specifically, as Figure 8-Figure 9 As shown, the adapter 142 and the controller 141 can be arranged on the same side of the mounting plate 143, so as to improve the compactness of the adapter 142 and the controller 141 when they are assembled to the tower fan 1. During assembly, the tower fan 1 is also provided with an adapter housing 16, which can be assembled on one side of the mounting plate 143, and an adapter mounting cavity can be defined in the adapter housing 16 for assembling the adapter 142. The adapter 142 is assembled in the adapter mounting cavity to avoid direct contact with the mounting plate 143 or other structures of the base 11, and the adapter housing 16 can enclose the high-voltage interface in the adapter mounting cavity, thereby improving the safety of the power cord 151 when electrically connected to the high-voltage interface. The controller 141 can be assembled on the side of the adapter housing 16 away from the mounting plate 143, realizing the scheme that the high-voltage interface and the low-voltage interface are separated from each other. The setting of the adapter housing 16 can protect the safety of the high-voltage interface, and at the same time, the power cord 151 and the wiring harness carrying the low-voltage current will not interfere with each other.

[0058] According to an embodiment of the present invention, a through hole 161 is formed on the adapter housing 16 for the power line 151 to pass through, and the through hole 161 is arranged on one side of the adapter housing 16 adjacent to the mounting plate 143. Specifically, as Figure 1 and Fig. 9As shown, when the adapter 142 is assembled to the adapter mounting cavity, the high-voltage interface is located in the adapter mounting cavity. At this time, a through hole 161 suitable for the power cord 151 to pass through can be processed on the adapter housing 16. During assembly, the power cord 151 passes through the mounting hole from the other side of the mounting plate 143 and enters the adapter mounting cavity through the through hole 161 and connects with the high-voltage interface. It is worth noting that when the adapter housing 16 is assembled with the mounting plate 143, the bottom of the adapter housing 16 can pass over the mounting plate 143, and the through hole 161 can be set on the side of the adapter housing 16 adjacent to the mounting plate 143 and located at the bottom of one side of the adapter housing 16 in the width direction. At this time, the power cord 151 passing through the mounting hole can directly enter the adapter mounting cavity through the through hole 161 without the power cord 151 being bent again, thereby avoiding damage to the power cord 151 due to multiple bending.

[0059] According to one embodiment of the utility model, Figure 1 and Figure 6 As shown, the tower fan 1 also includes a transfer line 152, one end of which is connected to the adapter 142, and the other end of which is connected to the controller 141; wherein, an open opening communicating with the adapter mounting cavity is formed on the side of the adapter housing 16 away from the mounting plate 143, and the controller 141 covers the open opening and is spaced apart from at least part of the edge of the open opening to form a communication gap 162 suitable for the transfer line 152 to pass through. After receiving the high-voltage alternating current transmitted by the power line 151, the adapter 142 can convert the high-voltage alternating current into low-voltage direct current. At this time, the tower fan 1 can be provided with a transfer line 152, one end of which is connected to the adapter 142, and the other end of which is connected to the controller 141. The low-voltage direct current converted by the adapter 142 can be directly transmitted to the controller 141 through the transfer line 152 so that the controller 141 can control the functional module 13 of the tower fan 1. An open opening is formed on the side of the adapter housing 16 facing away from the mounting plate 143, and the open opening is connected to the adapter mounting cavity. During assembly, the adapter 142 can be directly assembled into the adapter mounting cavity from the open opening, making the assembly of the adapter 142 more convenient. The controller 141 can cover the open opening to ensure that the adapter 142 does not fall off from the adapter mounting cavity. When the controller 141 is assembled with the adapter housing 16, a connecting gap 162 can be formed between the controller 141 and at least part of the edge of the open opening, and the adapter line 152 can directly pass through the connecting gap 162 to connect the adapter 142 to the controller 141.
