Description

Technical Field

[0001] This utility model relates to the field of heaters, and in particular to a double-sided convection heater. Background Technology

[0002] Heaters are common heating devices that convert electrical energy into heat. They are widely used for indoor heating in cold regions. Common types include tower heaters and baseboard heaters.

[0003] Tower heaters use forced convection fans, while baseboard heaters use natural water flow. Therefore, tower heaters deliver hot air more quickly, rapidly raising the temperature of a localized area. As people's living standards improve, higher demands are placed on heater performance. However, existing heaters are limited by the direction and range of their air outlets; in larger rooms, it may take a considerable amount of time to warm the entire space.

[0004] Therefore, it is necessary to invent a double-sided convection heater to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a dual-sided convection heater to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dual-sided convection heater, comprising a main unit and an outer shell, wherein the main unit includes an air supply unit, an air duct and a heating unit, and the outer shell has opposing air outlets on both circumferential sides, the air outlets being connected to the air duct of the main unit.

[0007] Optionally, the air supply unit includes a fan wheel equipped with a motor, and the air duct includes an air supply channel connected to the outlet end of the fan wheel and a diversion air duct connected to the air supply channel, wherein the diversion air duct is connected to the air outlets on both sides.

[0008] Optionally, an arc-shaped diversion plate is provided inside the diversion duct, and the length of the diversion plate extends towards the air outlet.

[0009] Optionally, there are two heating units, which are located on the housing of the main unit facing the air outlets on both sides.

[0010] Optionally, the housing of the host is provided with a lifting unit, which includes a lifting motor. The lifting motor is mounted on the housing of the host. The heating unit includes a PTC heating element and a PTC bracket for placing the PTC heating element. The lifting motor drives the PTC bracket to move vertically on the housing of the host.

[0011] Optionally, the output shaft of the lifting motor is connected to a drive gear, and the two PTC brackets are connected to a rack on the side near the main unit. The drive gear is meshed with a driven gear, and the two gears and the driven gear are coaxially connected through a connecting rod.

[0012] Optionally, the housing of the host extends outward toward the heating unit and is provided with a support frame. The rack and the support frame are slidably connected by a limiting protrusion and a matching limiting slider. The PTC bracket and the support frame are slidably connected by a positioning slider and a matching positioning groove.

[0013] Optionally, it also includes a base, and the outer casing includes a lower casing, on which a rotary motor is mounted for driving the main unit and the outer casing to rotate synchronously relative to the base.

[0014] Optionally, the maximum angle at which the main unit and the outer casing can rotate synchronously relative to the base is 120°.

[0015] Optionally, the host also includes a control circuit board and a voice transceiver assembly. The control circuit board is electrically connected to the motor of the wind turbine, and a touch panel is embedded in the front side of the housing. The control circuit board is electrically connected to the touch panel and the voice transceiver assembly.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model has opposing air outlets on the periphery of the outer shell, which are connected to the air duct of the main unit. Heated air is blown out from the air outlets on both sides, and the two sides of the heater form a double-sided convection circulation heating with the cold air in the outside space. The double-sided convection structure improves the circulation heating efficiency and achieves the effect of rapid circulation heating. It has the advantages of large air outlet range and high heating efficiency.

[0018] 2. This utility model uses a lifting unit to drive the heating unit to move vertically at the air outlet. When the heating unit is completely offset from the air outlet, the air coming out of the air duct is blown out directly from the air outlet without being heated by the heating unit, thus achieving the switching between hot and cold air, which is highly practical.

[0033] The following is for reference. Figures 1-9 This invention describes a dual-sided convection heater according to an embodiment of the present invention.

[0034] like Figures 1-9 As shown, a dual-sided convection heater according to an embodiment of the present invention includes a main unit 1 and an outer shell. The main unit 1 includes an air supply unit, an air duct, and a heating unit. The outer shell has opposing air outlets on both sides of its circumference, and the air outlets are connected to the air duct of the main unit 1.

[0035] In some specific embodiments, such as Figure 3As shown, the air supply unit includes a fan wheel 11 with a motor installed. The outlet end of the fan wheel 11 is connected to an air supply channel 12. The air supply channel 12 is connected to a diversion duct 13 for diverting air to both sides. An arc-shaped diversion plate 131 is provided in the diversion duct 13. The length of the diversion plate 131 extends towards the air outlet. The air supplied from the air supply channel 12 enters the diversion plate 131 of the diversion duct 13 and is diverted to the air outlets on both sides. There are two heating units. The two heating units are located on the housing of the main unit 1 facing the air outlets on both sides, realizing double-sided air supply and forming double-sided convection circulation, resulting in a wider air supply range and a significant improvement in heating efficiency.

[0036] In some specific embodiments, the main unit 1 is installed inside the outer casing. The main unit 1 also includes a control circuit board 7, which is electrically connected to the motor of the impeller 11. A touch panel is embedded in the front side of the front outer casing 6, and the control circuit board 7 is electrically connected to the touch panel to realize touch start-up, which is highly intelligent and convenient for users. The outer casing includes a right outer casing 3, a left outer casing 4, a rear outer casing 5, a front outer casing 6, and a lower outer casing 8. The air outlets on both sides are located at the right outer casing 3 and the left outer casing 4, respectively. The air outlet at the left outer casing 4 is the left air outlet 41, and the position of the left air outlet 41 is as follows: Figure 8 As shown, the right outer shell 3 and the left outer shell 4 have the same structure and are horizontally symmetrical. The air outlet at the right outer shell 4 is located on the horizontal opposite side of the left air outlet 41. This will not be described in detail in the attached diagram.

[0037] Specifically, the heating unit includes a PTC heating element 16 and a PTC bracket 15 for mounting the PTC heating element 16. There are two heating units, which are located on the right side of the main unit 1 facing the outer shell 3 and the left side of the outer shell 4, respectively.

[0038] In some specific embodiments, such as Figure 9 As shown, the lower part of the rear outer shell 5 is provided with an air inlet, which is connected to the inlet end of the impeller 11. A dustproof net 51 is detachably installed at the air inlet. The dustproof net 51 is provided with a nylon mesh to improve the filtration effect and prevent dust from clogging the impeller 11 and causing damage. The nylon mesh can also be replaced by fiberglass screen or other dustproof structures, which is common knowledge to those skilled in the art and will not be listed here.

[0039] In some other embodiments, such as Figure 9 As shown, the upper part of the rear shell 5 is provided with a recessed remote control fixing position 52. The remote control fixing position 52 is used to place the remote control 53 and facilitates the removal of the remote control 53. The structure is simple and beautiful, and the storage effect is good.

[0040] In some embodiments, such as Figure 9As shown, the surface of the rear outer shell 5 is provided with a sound hole 54. The main unit 1 is equipped with a voice transceiver component 112 on the side facing the rear outer shell 5. The voice transceiver component 112 is positioned corresponding to the sound hole 54 and is used for sound pickup and output, providing a device foundation for intelligent voice interaction. It can be composed of a microphone and a speaker. The voice transceiver component 112 is electrically connected to the control circuit board 7. The control circuit board 7 is provided with a temperature control module, which is electrically connected to the heating unit. The control circuit board 7 is electrically connected to the motor of the impeller 11. A touch panel is embedded in the front side of the front outer shell 6. The control circuit board 7 is electrically connected to the touch panel, realizing touch and voice interaction control of the start of the impeller 11 and the operation of the heating unit. It has a high degree of intelligence and is convenient for people to use.

[0041] In some embodiments, the housing of the main unit 1 is provided with a lifting unit for simultaneously driving two heating units to move vertically between the split air duct 13 and the air outlet. When the heating unit is completely offset from the air outlet, the air coming out of the split air duct 13 is blown directly out of the air outlet without being heated by the heating unit, thus achieving a switch between hot and cold air. In existing products, since the heating unit is usually fixed, although the heating temperature of the heating unit can be adjusted, the air volume is inevitably limited when heating is not needed because the heating unit is still located at the air outlet. This embodiment achieves a switch between hot and cold air through the lifting unit, expanding the application scenarios of the heater and making it more practical.

[0042] The lifting unit includes a lifting motor 19, which is mounted on the housing of the main unit 1 and drives the PTC bracket 15 to move vertically on the housing of the main unit 1. Specifically, as shown... Figure 2 and Figure 4 As shown, racks 17 are connected to the two PTC brackets 15 near the main unit 1. Gears 18 are meshed on the two racks 17 respectively. The output shaft of the lifting motor 19 is connected to a drive gear 191. The drive gear 191 is meshed with a driven gear. The two gears 18 and the driven gear are coaxially connected through a connecting rod 110. When the lifting motor 19 starts, the drive gear 191 rotates, and the driven gear and gear 18 rotate synchronously. The racks 17 on both sides that are meshed with the gears 18 drive the PTC brackets 15 and the PTC heating element 16 on both sides to move vertically between the split air duct 13 and the air outlet, thereby realizing the synchronous switching of hot and cold air on both sides.

[0043] It should be noted that the attached drawing uses a lifting structure consisting of a gear and rack. Other lifting structures, such as a combination of a lead screw and nut or a combination of a timing belt / chain and a pulley / sprocket, can also be used instead. These are ideas that can be conceived by those skilled in the art without creative effort, and will not be listed here.

[0044] In some specific embodiments, such as Figure 5 As shown, the outer casing of the main unit 1 extends outward toward the heating unit with a support frame 111. The rack 17 is provided with a limiting protrusion 171 at one end facing the support frame 111. The support frame 111 is provided with a limiting slider that cooperates with the limiting protrusion 171 near the rack 17. The rack 17 is slidably connected to the support frame 111 through the cooperation of the limiting protrusion 171 and the limiting slider. During the vertical displacement of the heating unit along the support frame 111, the limiting protrusion 171 limits the limiting slider laterally, making the movement of the heating unit more stable.

[0045] For better results, such as Figure 5 As shown, the support frame 111 is provided with a positioning groove on the side facing the PTC bracket 15, and the PTC bracket 15 extends a positioning slider 151 in the direction of the support frame 111. The positioning slider 151 slides in the positioning groove, and the PTC bracket 15 moves stably vertically on the side of the main unit 1 by being clamped by the support frame 111.

[0046] For better results, such as Figure 8 As shown, the outer frame of the left air outlet 41 extends longitudinally and is provided with a left limiting plate 42. The right outer shell 3 is also provided with a right limiting plate that is horizontally corresponding to the left limiting plate 42. Since the right outer shell 3 and the left outer shell 4 are symmetrical, those skilled in the art can easily understand this, and no further illustration is provided here. The left limiting plate 42 and the right limiting plate are used to provide limiting support for the downward movement of the heating unit.

[0047] In some embodiments, the present invention also includes a base 2, wherein the main unit 1 and the outer casing can rotate synchronously relative to the base 2 to achieve dual-sided air outlet and oscillation, and can rapidly heat up from multiple directions.

[0048] In some specific embodiments, such as Figure 6 and Figure 7As shown, the outer casing includes a lower casing 8, on which a rotary motor 9 is mounted. The output shaft of the rotary motor 9 is connected to a crank connecting rod 91. A rotating shaft 84 is located in the middle of the lower casing 8. Two arc-shaped first sliding grooves 82 and one arc-shaped second sliding groove 83 are arranged around the outer periphery of the rotating shaft 84. The two first sliding grooves 82 are arranged horizontally symmetrically. Positioning posts 21 are respectively arranged in the two first sliding grooves 82 and the second sliding groove 83 on the base 2. The end of the crank connecting rod 91 is connected to the positioning post 21 on the second sliding groove 83. When the rotary motor 9 is started, it drives the lower casing 8 to rotate as a whole. During the rotation of the lower casing 8, the two arc-shaped first sliding grooves 82 and the one arc-shaped second sliding groove 83 rotate relative to the positioning post 21. Compared with axial transmission, the transmission method of connecting the output shaft of the rotary motor 9 to the crank connecting rod 91 can reduce the vertical space occupied by the rotary motor 9, and the structure is simple and the layout is reasonable.

[0049] Preferably, the arc of the first slide groove 82 and the second slide groove 83 is 120°. Since the air outlets of the dual-sided convection heater in this embodiment are arranged on opposite sides and have a certain width, the synchronous rotation of the main unit 1 and the outer shell relative to the base 2 by 120° can achieve the effect of 360° rotation of the single-sided air outlet. On the basis of dual-sided air outlet, the addition of a rotating mechanism improves the heating efficiency and achieves rapid heating. On the other hand, it reduces the problem of wire winding that occurs in the traditional single-sided air outlet rotation, making it more practical, more efficient in heating, and better in heating effect.

[0050] In some specific embodiments, for better results, such as Figure 7 As shown, a ball bearing 81 is provided at the bottom of the lower housing 8, and a slide rail is provided on the base 2 to match the movement trajectory of the ball bearing 81. When the main unit 1 and the outer housing are synchronously relative to the base 2, the ball bearing 81 rolls in the slide rail, which limits the movement on the one hand and greatly reduces the friction on the other hand, making the rotation of the main unit 1 and the outer housing smoother.

[0051] The working principle and technical effect of the above technical solution adopts a structure with air outlets on both sides. Specifically, after being powered on, the impeller 11 draws in external air from the rear shell 5 into the air supply channel 12, and then blows it to the heating units on both sides through the diversion air channel 13. After being heated at a uniform speed by the heating units, it is blown to the outside from the air outlets on both sides, achieving the effect of rapid heating. After the internal air of the heater is heated, the hot air automatically rises, forming a convection circulation heating with the cold air in the outside space, ensuring that the heated space is heated in a circulating manner. The dual-sided convection heating mechanism design greatly improves the circulation heating efficiency. In addition, a lifting unit is used to vertically drive the heating unit. A lifting motor 19 simultaneously drives the heating units on both sides to rise and fall. When the heating unit is completely offset from the air outlet, the air coming out of the air duct is blown directly out of the air outlet without being heated by the heating unit, realizing the simultaneous switching of hot and cold air on both sides. Furthermore, the main unit 1 and the outer casing can rotate and oscillate, which on the one hand improves the heating efficiency and realizes rapid heating in multiple directions. On the other hand, the dual-sided air outlet structure reduces the requirement for the rotation angle and avoids the problem of wire tangling that is easy to occur when rotating with a traditional single-sided air outlet.
