Description

Electric heater with air outlet on both sides

Technical Field

The utility model relates to the technical field related to electric heating devices, and in particular to an electric heater with air outlets on both sides.

Background Art

Existing electric heating fans generally have air outlets on only one side. For example, Chinese patent CN101988516A discloses a cooling and heating dual-purpose electric fan. Chinese patent CN106032801A discloses a cooling and heating dual-purpose electric fan. Although these two fans can meet the use requirements of most scenarios, they cannot meet the use requirements of all scenarios. For example, hot air can be directional-delivered to two locations at the same time from one location. Although this can be achieved by placing two electric heating fans, it takes up space and increases the cost of use. Therefore, it is urgently necessary to design a device that can output hot air in multiple directions to meet the use of such scenarios.

Utility Model Content

In order to overcome the existing technical defects, the purpose of the utility model is to provide an electric heater with air outlets on both sides to solve the above technical problems.

The technical solution adopted by the utility model to solve the technical problem is as follows:

According to one aspect of the utility model, an electric heater with air outlet on both sides is designed, comprising: a shell, an air outlet tube, a motor, fan blades and a heating unit, the shell is provided with an air inlet, the air outlet tube is provided with air outlets at least at left and right ends, the shell is connected to the air outlet tube, and the interior of the shell is connected to the interior of the air outlet tube, the motor is installed in the shell, and its output shaft is connected to the fan blades, and the heating unit is arranged on the air outlet side of the fan blades.

By adopting the above technical scheme, when air outlets are provided at the left and right ends of the air outlet duct, when the electric heater is in use, the motor drives the fan blades to rotate, which can drive the external air into the shell from the air inlet, and heat it to form hot air when passing through the heating unit. After that, the hot air enters the air outlet duct and is divided into two streams, and is output from the air outlets at the left and right ends of the air outlet duct respectively, thereby realizing the output of hot air on both sides, and thus meeting the use requirements of scenarios requiring directional hot air output on both sides. When air outlets are provided at the left and right ends of the air outlet duct and air outlets are also provided on other sides or/and the top, when the electric heater is in use, in addition to the left and right ends being able to output hot air, other sides or/and the top will also output hot air, thereby realizing multi-directional positioned output of hot air. In addition, compared with the use of two electric heating fans, the footprint is relatively small and the cost is relatively low, saving the use cost.

In order to better solve the above technical defects, the utility model also has a better technical solution:

In some embodiments, it further includes a base and a support rod, wherein the upper end of the support rod is connected to the shell or the air outlet tube, and the lower end of the support rod is connected to the base.

In some embodiments, the shell is perpendicular to the air outlet, and the shell is connected to the middle of the air outlet, thereby ensuring that the hot air output from the shell is evenly divided into two streams after entering the air outlet, and is output from the air outlets on both sides at the same time, ensuring the stability of the structure and uniform air output on both sides.

In some embodiments, the lower end of the support rod is fixedly connected to the base, and the upper end is connected to the shell or the air outlet tube.

In some embodiments, the air outlet is provided at both ends of the air outlet, or the left and right ends and the top of the air outlet are provided with air outlets, or the left and right ends and the front and back sides of the air outlet are provided with air outlets, or the left and right ends, the front and back sides and the top of the air outlet are provided with air outlets.

In some embodiments, the heating unit is a PTC heating element, a heating wire, or a heating tube.

In some embodiments, the air inlet is arranged on the bottom and/or the lower side wall of the shell, or the air inlet is arranged on the top and/or the upper side wall of the shell.

In some embodiments, a first mounting frame is provided in the housing, and the heating unit is mounted on the first mounting frame.

In some embodiments, an air outlet cover is provided in the air outlet.

In some embodiments, the air outlet is provided with a second mounting frame connected to the air outlet cylinder, the air outlet cover is rotatably connected to the second mounting frame, the air outlet cover includes a mounting seat, a first annular member, and a plurality of air guide plates, the plurality of air guide plates are evenly distributed in a circle, one end of the air guide plates is connected to the mounting seat, and the other end is connected to the first annular member, and the angle between the air guide plates and the air outlet direction of the air outlet cylinder is 5-35°. Thus, when the hot air flow in the air outlet cylinder passes through the air outlet cover, the air outlet cover can be driven to rotate, so that the hot air can be output in a diffused state, and the air outlet effect is better.
