  The present invention belongs to the field of electric heaters, and particularly relates to a wide range electric heater.

  Electric heaters are widely used as movable heaters in houses, offices, hotels, department stores, hospitals, schools, train cars, etc., and in various private and public buildings such as simple houses. Moreover, the electric heater has a function of radiation and convection, and usually includes a high-efficiency aluminum alloy radiating fin inside. Therefore, it has a strong radiation capacity, a large radiation area, and is very useful as a heater in winter.

  However, since the electric heaters currently on the market are all provided on one side of the body, the hot air can be blown only in a specific direction during use, and the hot air blowing range is narrow. It has become. In order to expand the blowing range of the warm air, the conventional warm air machine is provided with a swing member added to a head provided with an exhaust port. For this reason, since the head can be swung back and forth within a certain angle range in the horizontal direction, the hot air blowing range can be expanded. However, such a warm air machine has a complicated structure of the swing member, and the production cost is high. And since the rocking | fluctuation range is 90 degrees or less normally by the restriction | limiting of the structure of a rocking | swiveling member, there exists a restriction | limiting with respect to a warm air ventilation range. In addition, since the air inlets are usually formed in a lattice shape, the air intake effect is poor and the heating effect is not ideal. In addition, conventional movable electric heaters are usually configured so that the handle can be rotationally connected to the electric heater for the purpose of movement, but wear tends to occur due to the rotation of the rotationally connected handle. It is not good and looks bad.

  In view of the above-mentioned deficiencies of the prior art, the present invention aims to provide a wide range electric heater that can solve the problem that the hot air blowing range of the electric heater in the prior art is narrow and the heating effect is not ideal. And

  In order to solve the above technical problem, the present invention provides the following technical solutions. The wide-range electric heater includes a housing provided with an intake port and an exhaust port, a blower provided in the housing, a PTC heating element, and a control module. The control module includes a blower and a PTC heating element. Each of the wide-range electric heaters is electrically connected, and further includes a base provided under the casing, and a motor provided on the base for driving the casing to rotate. The PTC heating element is formed in a lattice shape, and the wide range electric heater further includes a temperature regulator provided in a housing and a guard that covers an exhaust port, and the temperature adjustment The vessel is electrically connected to the control module, and a non-slip support leg is provided under the base.

  In a further preferred aspect of the present invention, the wide range electric heater further includes a lifting support that is detachably attached to the base.

  In a further preferred aspect of the present invention, the wide-range electric heater further includes an LED lamp provided in the housing and electrically connected to the control module.

  In a further preferred aspect of the present invention, a fall prevention switch that is electrically connected to the control module is further provided in the housing.

  In a further preferred embodiment of the present invention, the casing is made of an ABS flame retardant material.

The beneficial effects of the present invention are as follows.
By providing a base under the casing of the electric heater and providing a motor for rotationally driving the casing on the base, the hot air blowing range can be effectively expanded. Moreover, since the handle groove for hand-holding is further provided in the housing, the durability of the hand-holding portion can be improved and the appearance can be improved.

  Hereinafter, the present invention will be described in more detail with reference to the drawings and embodiments.

It is another perspective view of the wide range electric heater in the Example of this invention.

  A preferred embodiment of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1 to 4, the wide range electric heater of the present embodiment includes a housing 1 provided with an intake port 11 and an exhaust port 12, a blower 2 provided inside the housing 1, and a PTC heating element 3. And a control module. The control module is electrically connected to the blower 2 and the PTC heating element 3, respectively. The wide-range electric heater further includes a base 4 provided below the housing 1 and a motor 5 provided on the base 4 and configured to rotationally drive the housing 1. On one side of the housing 1, a handle groove 13 for carrying is further provided, and the PTC heating element 3 is formed in a lattice shape. The wide-range electric heater further includes a temperature regulator provided in the housing 1 and a guard 6 that covers the exhaust port. The temperature regulator is electrically connected to the control module, and a non-slip support leg 41 is provided under the base 4. By providing the base 4 under the housing 1 of the electric heater and providing the motor 5 for rotating the housing 1 on the base 4, the hot air blowing range can be effectively expanded. In addition, since the handle 1 is further provided with a handle groove 13 for hand-holding, the durability of the hand-holding portion can be improved and the appearance can be improved. By forming the PTC heating element 3 in a lattice shape, the heat generation effect can be effectively improved, and the hot air blown out becomes more uniform, and the heating effect can be improved. Further, since the air inlets 11 are formed in a rounded grid shape, it is possible to prevent foreign matter from entering the housing 1 and breaking the blower 2 and to effectively reduce the airflow resistance and noise. A non-slip support leg 41 is provided under the base 4. By providing a plurality of anti-slip support legs 41 under the base 4, it is possible to effectively prevent the housing 1 from slipping.

  Furthermore, the temperature regulator includes a thermo switch and a thermal fuse. The double monitoring of the thermo switch and the thermal fuse can be used in a safer manner because it can be shut off when the temperature of the heating element is too high. The housing 1 is made of a flame retardant material such as ABS (acrylonitrile butadiene styrene). The ABS flame retardant material is also called ABS resin and is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical performance, is easy to process, has stable product dimensions, and has excellent surface gloss. When the casing 1 is made using an ABS flame-retardant material, the flame retardancy of the casing 1 can reach V0, and the occurrence of flame can be prevented, so that it can be used more safely. In the housing 1, a fall prevention switch electrically connected to the control module is further provided. The fall prevention switch is a general switch that turns off the operation when the vertical electric product is tilted. When the tilt angle of the electrical product is too large or tilted, the fall prevention switch automatically cuts off and stops the operation of the electrical product. By adding the fall prevention switch, it is possible to effectively prevent the occurrence of a fire or the like due to the tilting of the electric heater.

  Furthermore, as shown in FIGS. 1 to 4, the wide range electric heater further includes a lifting support that is detachably attached to the base 4. Since the height of the electric heater can be adjusted according to the user's needs, the heat dissipation effect can be improved and the user's experience can also be improved. The wide-area electric heater further includes an LED lamp provided in the housing 1, and the LED lamp is electrically connected to the control module. By adding an LED lamp and making an electrical connection, the brightness of the LED lamp can be adjusted according to the room temperature. That is, by setting the LED lamp, the illumination function can be realized and the indoor temperature can be displayed. Therefore, the LED lamp can be used and has a good appearance.
