Description

Technical Field

[0001] The utility model belongs to the technical field of heater products, and particularly relates to an internal circulation ceiling heater. Background Art

[0002] A heater refers to a device used for heating. There are many types of heaters. The most common electric heater is a heating device that uses electricity as energy for heating. It uses an electric motor to drive the turbine to rotate to generate air flow through the PTC heating block to provide heating.

[0003] A Chinese patent with announcement number CN217604218U discloses a long strip heater, comprising a shell and a base plate fixedly connected to the lower end surface of the shell; a PTC heating block is installed inside the shell, the PTC heating block is long and is arranged in the warm air outlet along the length direction of the base plate; a protective cover for installing the PTC heating block is provided in the warm air outlet, and a plurality of through slots are provided at the bottom of the protective cover; two turbine assemblies are provided at one end of the PTC heating block, and the two turbine assemblies are arranged side by side along the length direction of the base plate; a junction box is provided between the two turbine assemblies.

[0004] The heater in the above-mentioned prior art installs a long PTC heating block at one end of the base plate along the length direction of the base plate of the heater, so that the heater is suitable for installation on the ceiling of narrow areas such as corridors, and can enhance the internal circulation air circulation in narrow areas. However, in actual use, we found that there are still some shortcomings. For example, the air outlet of the traditional heater can usually only blow in a fixed direction, and the blowing direction cannot be adjusted according to the needs of the user. Therefore, there are still technical bottlenecks in use. Utility Model Content
