Embodiment 1

[0089] Such as Figure 1-4 As shown, this embodiment discloses a heating device 10 , which includes at least two heating components arranged at intervals, and each heating component includes a support plate 102 and a heating assembly 101 connected to the support plate 102 . The position where the heating component is located can form an air flow path that communicates with the interval area of ​​at least two heating components.

[0090] In this embodiment, the heating device 10 includes at least two heating components arranged at intervals, so as to realize the heating of multiple areas, and can be applied to structures with a small overall volume and requiring multi-area heating (such as hand dryers). . In addition, the existence of the airflow passage facilitates the circulation of the gas, thereby helping to reduce the flow resistance and reduce the influence on the air outlet effect of the hand dryer. For example, when the heating device 10 is applied to a hand dryer, it...

Embodiment 2

[0137] This embodiment discloses a heating device, such as Figure 1-4 As shown, the heating device 10 includes a mounting plate 103, at least two supporting plates 102 and at least two heating components. Wherein, a connection structure is provided on the installation board 103 . At least two supporting boards 102 are disposed on the mounting board 103 at intervals. At least two heating components are wound on at least two support plates 102 correspondingly. in, Figure 1-4 Only two support plates 102 and two heating assemblies are schematically shown in .

[0138] In this embodiment, the connecting structure on the mounting plate 102 facilitates the connection between the heating device and the external structure (such as the connecting piece in the above-mentioned embodiment 1), so as to realize the fixing of the heating device. At least two heating assemblies are arranged on at least two support plates arranged at intervals, so that at least two heating assemblies are ...

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...
