Heating device and hand dryer comprising same

Abstract

The invention discloses a heating device and a hand dryer comprising the same. The heating device comprises at least two heating parts arranged at intervals, and each heating part comprises a supporting plate and a heating assembly connected to the supporting plate. An air flow channel communicated with the interval areas of the at least two heating parts can be formed in the position where the heating parts are located. The hand dryer comprises: a housing; at least two air outlet pipeline assemblies communicating with the shell, wherein air outlets are formed in the air outlet pipeline assemblies, and the at least two air outlet pipeline assemblies are arranged at intervals; and the heating device. The heating parts are arranged adjacent to the corresponding air outlet pipeline assemblies, the heating parts and the air outlets are at least partially arranged in a staggered mode, and the interval areas of the at least two heating parts and the interval areas of the at least two air outlet pipeline assemblies at least partially coincide. The air flow channel is communicated between the shell and the air outlets. The air flow reaches the air outlets through the overlapped or partially overlapped interval areas, flowing of the air flow is basically not blocked through the arrangement of the heating assemblies, and the air outlet effect of the hand dryer is not affected.

Description

【Technical field】 [0001] The invention relates to the field of hand dryers, in particular to a heating device and a hand dryer comprising the same. 【Background technique】 [0002] Hand dryers are generally divided into two types: heating type and high-speed air drying type. The heating-based hand dryer usually has a relatively large heating power, above 1000W, while the motor power is very small, less than 200W. , Take away the water on the hands. This method dries hands slowly, usually more than 30 seconds. The high-speed air hand dryer is characterized by a very high wind speed, which can reach more than 130 m / s, the drying speed is about 10 seconds, and the heating power is relatively low, only a few hundred watts, and its heating function is only to maintain comfort , basically does not affect the speed of drying hands. However, the noise generated by the high wind speed is relatively large. [0003] Hand dryers are widely used at present, and are generally used in o...

Problems solved by technology

[0004] Among them, in the prior art, the high-speed air drying type hand dryer is rarely provided with a heating device

And the hand dryer that includes heating device, such as the hand dryer with wall-mounted structure disclosed in the Chinese patent application with publication number CN203354447U, its heating wire structure is a heating wire winding, which has a large volume and can only be used for certain One whole zone is heated, not suitable for hand dryers with small overall volume and multi-zone heating
