Description

Technical Field

[0001] The utility model relates to a fan, in particular to a heatable air curtain machine. Background Art

[0002] In order to improve the user experience of the air curtain machine, some air curtain machines are equipped with heaters to heat the outlet air. The current heating method is generally to set a PTC heating tube at the air outlet of the air curtain machine. When the air is blown out from the air outlet, the PTC heating tube heats the outlet air. However, since the PTC heating tube occupies a large space at the air outlet, the air outlet volume will be seriously reduced, which will affect the normal use of the air curtain machine and easily lead to a large wind pressure inside the air curtain machine, affecting its structural stability. Therefore, a heating air curtain machine with a more reliable structure is urgently needed. Utility Model Content

[0003] The utility model aims to provide a heatable air curtain machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A heatable air curtain comprises: a casing, one side of which is provided with an air inlet, and the bottom side of which is provided with an air outlet, a guide plate being connected to the side of the casing away from the air outlet, the guide plate being inclined upward and extending toward the direction close to the air inlet to the top side of the casing; a fan connected to the casing, the fan being closer to the air inlet than the guide plate, the area in the casing between the fan and the air inlet being the air inlet area; and a quartz heating tube being arranged in the air inlet area.

[0006] This technical solution has at least the following beneficial effects: when the fan is working, air is drawn into the casing from the air inlet on one side of the casing, and is discharged from the air outlet on the bottom side of the casing after being guided by the guide plate. When the outlet air needs to be heated, the quartz heating tube is turned on. Since the volume of the quartz heating tube is relatively small, the flow blocking effect on the air during air intake is reduced. The air can first enter the air inlet area for buffering, and after being heated by the quartz heating tube, it is finally blown out from the air outlet. In this way, the quartz heating tube is set at the air inlet position to directly heat the intake air, which effectively reduces the impact on the intake air volume, thereby achieving the function of stable output of hot air.

[0007] As a further improvement of the above technical solution, a mounting frame is connected between the inner top side and the inner bottom side of the casing, and the mounting frame is provided with slots on both sides of the casing along the length direction facing the air inlet, and the two ends of the quartz heating tube are respectively inserted into the two slots. The mounting frame is connected between the inner top side and the inner bottom side of the casing, which can enhance the stability of the casing itself and make it less likely to deform. The mounting frame is provided with slots at the positions of the two sides of the air inlet along the length direction of the casing. When the quartz heating tube needs to be installed, the two ends of the quartz heating tube can be directly inserted into the two slots, and the quartz heating tube can be quickly installed and positioned, thereby improving the convenience and stability of the installation of the quartz heating tube.

[0008] As a further improvement of the above technical solution, a plurality of quartz heating tubes are arranged at intervals in the vertical direction. The plurality of quartz heating tubes are arranged at intervals in the vertical direction, which can reduce the obstruction of the quartz heating tubes to the airflow. When the air enters from the air inlet, it is heated by the plurality of quartz heating tubes, which can improve the heating effect of the air.

[0009] As a further improvement of the above technical solution, a reinforcement plate is connected to the middle of the mounting frame, and an elastic buckle is arranged on the side of the reinforcement plate facing the air inlet, and the elastic buckle includes two elastic sheets connected to the reinforcement plate at intervals, and the middle parts of the two elastic sheets are arched in the direction away from each other. The reinforcement plate can enhance the structural stability of the middle position of the mounting frame and further strengthen the overall structure. In addition, two elastic sheets arranged at intervals are connected to the reinforcement plate, and the middle parts of the two elastic sheets are arched to form an elastic clamping space. When installing the quartz heating tube, the quartz heating tube can be inserted into the elastic clamping space, and the two elastic sheets are squeezed and pushed open in the direction away from each other. When the quartz heating tube is installed in place, the two elastic sheets clamp the quartz heating tube in place, so that the middle part of the quartz heating tube can be supported, the installation stability of the quartz heating tube can be improved, and the middle part of the quartz heating tube can be prevented from falling.

[0010] As a further improvement of the above technical solution, the ends of the two elastic sheets away from the reinforcing plate are bent in a direction away from each other to form a guide section. The two elastic sheets respectively form a guide space at the position of the guide section that gradually expands in a direction away from the reinforcing plate, so that the quartz heating tube can be directly inserted from the guide space into the inside of the two elastic sheets, thereby further improving the convenience of installing the quartz heating tube.

[0011] As a further improvement of the above technical solution, an electrical appliance fixing frame is connected between the inner top side and the inner bottom side of the housing. The electrical appliance fixing frame can further enhance the structural stability between the inner top side and the inner bottom side of the housing, and electrical components such as circuit boards can be installed on the electrical appliance fixing frame to better utilize the space in the air inlet area.

[0012] As a further improvement of the above technical solution, an air outlet frame is provided in the housing, and the air outlet frame and the side of the housing away from the air inlet are surrounded to form an air outlet area, and the air outlet is located at the bottom of the air outlet area. The air outlet frame is located at the air outlet position of the housing, which can further improve the structural stability of the air outlet, effectively prevent the air outlet position from vibrating and loosening, and the air outlet area formed by the air outlet frame and the housing can easily gather air to ensure the air output.

[0013] As a further improvement of the above technical solution, a wind shield is connected to the top side of the air outlet frame near the air inlet, and the wind shield extends upward along a position close to the bottom of the fan. The wind shield can reduce the air entering the casing from the air inlet from directly flowing from the space below the fan to the air outlet area, which is beneficial to reduce the turbulence of the fan outlet and improve the effect of guiding the fan outlet.

[0014] As a further improvement of the above technical solution, a hanging plate is connected to the outer side of the housing away from the air inlet, and a mounting hole is provided on the hanging plate. When the housing is installed, the hanging plate can strengthen the structural strength of the housing installation position, so that it is not easy to deform when installed and hung for a long time. By driving screws or bolts or other connecting parts into the mounting holes of the hanging plate to fix the hanging plate, the whole can be installed stably.

[0015] As a further improvement of the above technical solution, the housing is provided with an air guide plate at the position of the air outlet. When the air is blown out from the air outlet, the air can be guided by the air guide plate, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figure 1 , Figure 2 and Figure 3A heatable air curtain comprises a housing 100, a fan 200 and a quartz heating tube 300, wherein an air inlet 110 is arranged on one side of the housing 100, for example, the housing 100 can extend in the front-to-back direction, and the air inlet 110 is arranged on the left or right side of the housing 100, and an air outlet 120 is arranged on the bottom side of the housing 100, and a guide plate 130 is connected to a side of the housing 100 away from the air outlet 120, and the guide plate 130 is designed in an arc shape, and the guide plate 130 extends upwardly and obliquely toward the direction close to the air inlet 110 to the top side of the casing 100. The guide plate 130 can be arranged to be straight and oblique, or can be arranged to be inclined in an arc shape. The fan 200 is connected to the casing 100. The fan 200 is closer to the air inlet 110 than the guide plate 130. The area in the casing 100 between the fan 200 and the air inlet 110 is the air inlet area, and the quartz heating tube 300 is arranged in the air inlet area.

[0026] As can be seen from the above, when the fan 200 is working, air is drawn into the casing 100 from the air inlet 110 on one side of the casing 100, and after being guided by the guide plate 130, it is discharged from the air outlet 120 on the bottom side of the casing 100. When it is necessary to heat the outlet air, the quartz heating tube 300 is turned on. Since the volume of the quartz heating tube 300 is relatively small, the flow blocking effect on the air during air intake is reduced. The air can first enter the air intake area for buffering, and after being heated by the quartz heating tube 300, it is finally blown out from the air outlet 120. In this way, the quartz heating tube 300 is set at the air inlet 110 to directly heat the intake air, which effectively reduces the impact on the intake air volume, thereby achieving the function of stable output of hot air.

[0027] The quartz heating tube 300 can be directly connected to the casing 100. In order to further improve the overall structural stability, in the present embodiment, a mounting bracket 140 is connected between the top side and the bottom side of the casing 100. The mounting bracket 140 is directly opposite to the air inlet 110 and is provided with slots 141 on both sides along the length direction of the casing 100. The two ends of the quartz heating tube 300 are respectively inserted into the two slots 141. The mounting frame 140 is connected between the inner top side and the inner bottom side of the casing 100, which can enhance the stability of the casing 100 itself and prevent the casing 100 from being deformed easily. Slots 141 are respectively arranged on the mounting frame 140 at positions on both sides of the air inlet 110 along the length direction of the casing 100. When the quartz heating tube 300 needs to be installed, the two ends of the quartz heating tube 300 can be directly inserted into the two slots 141 respectively, and the quartz heating tube 300 can be quickly installed and positioned, thereby improving the convenience and stability of the installation of the quartz heating tube 300.

[0028] In actual applications, the mounting frame 140 includes two side panels arranged along the front-to-back direction and a horizontal panel connected between the two side panels. At this time, two slots 141 can be formed on the two side panels respectively, the horizontal panel is connected to the inner top side of the casing 100, and the bottom sides of the two side panels are connected to the inner bottom side of the casing 100.

[0029] In order to improve the heat exchange efficiency when air enters, in this embodiment, a plurality of quartz heating tubes 300 are arranged at intervals along the vertical direction. Correspondingly, a plurality of slots 141 are arranged at intervals along the vertical direction on both sides of the mounting frame 140 along the length direction. Two mutually opposite slots 141 form a group, and a plurality of quartz heating tubes 300 can be respectively installed in a plurality of groups of mutually opposite slots 141. The plurality of quartz heating tubes 300 are arranged at intervals along the vertical direction, which can reduce the obstruction of the quartz heating tubes 300 to the air flow. When the air enters from the air inlet 110, it is heated by the plurality of quartz heating tubes 300, which can improve the heating effect of the air.

[0030] When the quartz heating tube 300 is long, the middle part is prone to fall down, resulting in the quartz heating tube 300 being installed unstable. Therefore, in this embodiment, a reinforcing plate 150 is connected to the middle part of the mounting frame 140, and an elastic buckle 151 is provided on the side of the reinforcing plate 150 facing the air inlet 110. The elastic buckle 151 includes two elastic sheets connected to the reinforcing plate 150 at intervals, and the middle parts of the two elastic sheets are arched away from each other. The reinforcement plate 150 can enhance the structural stability of the middle position of the mounting frame 140 and further strengthen the overall structure. Two elastic sheets are connected to the reinforcement plate 150 at intervals. The middle parts of the two elastic sheets are arched to form an elastic clamping space. When installing the quartz heating tube 300, the quartz heating tube 300 can be inserted into the elastic clamping space, and the two elastic sheets are squeezed and pushed away from each other. When the quartz heating tube 300 is installed in place, the two elastic sheets clamp the quartz heating tube 300 in place. In this way, the middle part of the quartz heating tube 300 can be supported, the installation stability of the quartz heating tube 300 is improved, and the middle part of the quartz heating tube 300 is prevented from falling.

[0031] In the above embodiment, if the quartz heating tube 300 needs to be directly installed between the two elastic sheets, it is necessary to apply external force to the two elastic sheets to open them, thereby expanding the clamping space between the two elastic sheets. Therefore, in order to facilitate opening the two elastic sheets, in this embodiment, the ends of the two elastic sheets away from the reinforcing plate 150 are bent in a direction away from each other to form a guide section. The two elastic sheets respectively form a guide space at the position of the guide section that gradually expands in the direction away from the reinforcing plate 150, which can facilitate the quartz heating tube 300 to be directly inserted from the guide space into the inside of the two elastic sheets, thereby further improving the convenience of installing the quartz heating tube 300.

[0032] In order to facilitate the installation of electrical components such as circuit boards, in this embodiment, an electrical appliance fixing frame is connected between the inner top side and the inner bottom side of the housing 100. The electrical appliance fixing frame can further enhance the structural stability between the inner top side and the inner bottom side of the housing 100, and electrical components such as circuit boards can be installed on the electrical appliance fixing frame, thereby better utilizing the space in the air intake area.

[0033] In some embodiments, an air outlet frame 160 is provided in the housing 100, and the air outlet frame 160 and the side of the housing 100 away from the air inlet 110 are surrounded to form an air outlet area, the air outlet 120 is located at the bottom side of the air outlet area, and the air outlet frame 160 is surrounded inside the housing 100. There are many structural forms, for example, the air outlet frame 160 includes two side frames, a connecting plate connected between the two side frames, the two side frames are arranged along the length direction of the housing 100, and are connected to the inner side of the housing 100, and the two side plates, the connecting plate and the housing 100 are surrounded to form an air outlet area. The air outlet frame 160 is located at the air outlet 120 of the housing 100, which can further improve the structural stability of the air outlet, effectively prevent the air outlet position from being easily vibrated or loosened, and the air outlet area formed by the air outlet frame 160 and the housing 100 can easily gather air to ensure the air volume.

[0034] The fan 200 is a cross-flow fan 200. In order to increase the air volume, in this embodiment, the air outlet frame 160 is connected to a windshield 161 at the top side close to the air inlet 110. The windshield 161 extends upward along a position close to the bottom of the fan 200. The windshield 161 can reduce the air entering the housing 100 from the air inlet 110 and directly flows from the space below the fan 200 to the air outlet area, which is beneficial to reduce the turbulence of the air outlet of the fan 200 and improve the air outlet guiding effect of the fan 200. In addition, the top side of the windshield 161 can be bent downward to form a bent section, so as to further enhance the structural stability of the windshield 161, so that the windshield 161 is not easily deformed.

[0035] When it is necessary to fix the whole, usually a hole is directly opened on the housing 100 and a connecting structure such as a hook is driven into it, so as to conveniently fix the whole. In order to further improve the structural stability of the installation position of the housing 100, in this embodiment, the housing 100 is connected to the outer side away from the air inlet 110 with a hanging plate 400, and the hanging plate 400 is provided with a mounting hole. When installing the housing 100, the hanging plate 400 can strengthen the structural strength of the installation position of the housing 100, so that it is not easy to deform when it is installed and hung for a long time. By driving screws or bolts and other connecting parts into the mounting holes of the hanging plate 400 to install and fix the hanging plate 400, the whole can be stably installed. In actual application, there is a certain gap between the middle position of the hanging plate 400 and the housing 100. The hanging plate 400 is installed on the housing 100 by bending the upper and lower sides to form a connecting flange, and a hole is hollowed out in the middle position of the hanging plate 400, which can reduce the weight of the hanging plate 400 and reduce the overall production cost.

[0036] In some embodiments, an electric control box may be provided on the top side of the housing 100 , and electrical components such as switches may be installed in the electric control box, thereby facilitating control and adjustment of the working state of the quartz heating tube 300 .

[0037] In order to conveniently control the direction of the air outlet, in this embodiment, the housing 100 is provided with an air guide plate 121 at the position of the air outlet 120. When the air is blown out from the air outlet 120, the air can be guided by the air guide plate 121 to improve the user experience. In actual application, the air guide plate 121 is rotatably connected to both sides of the air outlet frame 160, and a motor is also configured in the housing 100 to control the swing of the air guide plate 121, so as to realize automatic adjustment of the air outlet direction.
