Description

Technical Field

[0001] The utility model relates to the technical field of bathroom heaters, in particular to an air-heating bathroom heater. Background Art

[0002] A bathroom heater is a small household appliance commonly used in home bathrooms. It is the preferred heating device for many families when bathing. The bathroom heaters on the market are mainly divided into lamp-heated bathroom heaters and air-heated bathroom heaters. Traditional air-heated bathroom heaters mostly use PTC ceramic heating sheets, which have small slits, resulting in greater wind resistance, louder blowing noise, and longer startup preheating time. In addition, some bathroom heaters require special-shaped heating elements, and the process of making special-shaped PTC ceramic heating sheets is complicated and the production cost is high. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides an air-heating type bathroom heater to solve the problems of high blowing noise, long start-up preheating time and high production cost.

[0004] To solve the above problems, the technical solution of the utility model is as follows: a wind-heated bathroom heater, comprising a shell and a mask, a blowing wheel assembly is arranged in the shell, and an air duct connected with the blowing wheel assembly is arranged on one side of the blowing wheel assembly, the air duct comprises a pipe wall, and an air inlet and an air outlet are arranged at both ends of the pipe wall, the air outlet is connected to the mask, a heating element assembly is arranged at the air inlet or the air outlet, and an air guide cone is arranged at the air outlet, the heating element assembly comprises a plurality of heating sheets arranged at intervals, and a positive electrode and a negative electrode are arranged at both ends of the heating sheet, and the positive electrode and the negative electrode are electrically connected to the bathroom heater.

[0005] Furthermore, the heating sheet is a mica sheet, and a heating coating is provided on the outside of the mica sheet.

[0006] Furthermore, the heat-generating coating is graphene.

[0007] Furthermore, the heating sheets are connected in parallel.

[0008] Furthermore, an air change wheel assembly for indoor ventilation is provided on one side of the air duct.

[0009] Furthermore, the blowing wheel assembly includes a fan chamber, in which a fan is arranged.

[0010] Furthermore, a lighting assembly is provided in the air guide cone.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by using mica sheets and graphene coatings, the heating efficiency is greatly improved and the preheating time is shortened; the heating sheets can be set at appropriate intervals, and the gaps are larger, which can reduce wind resistance and noise; the wind guide cone guides the hot air to flow in a streamlined manner, reducing wind resistance and noise; a single heating sheet can be shaped into a special shape, and the heating body formed by the heating sheets can also be shaped into a special shape, which is simple to shape and has a low cost.

[0018] like Figure 1-Figure 5 As shown, a wind-heated bathroom heater comprises a shell 1 and a mask 2. A blowing wind wheel assembly 3 is arranged in the shell 1. An air duct connected to the blowing wind wheel assembly 3 is arranged on one side of the blowing wind wheel assembly 3. The air duct comprises a pipe wall 4. An air inlet 5 and an air outlet 6 are arranged at both ends of the pipe wall 4. The air outlet 6 is connected to the mask 2. A heating element assembly is arranged at the air inlet 5 or the air outlet 6. An air guide cone 7 is arranged at the air outlet 6. The heating element assembly comprises a plurality of heating sheets 8 arranged at intervals. A positive electrode and a negative electrode are arranged at both ends of the heating sheet 8. The positive electrode and the negative electrode are electrically connected to the bathroom heater. The heating sheets 8 are connected in parallel.

[0019] The heating sheet 8 is a mica sheet, and a heating coating is provided outside the mica sheet, and the heating coating is graphene.

[0020] An air change wheel assembly 9 for indoor ventilation is provided on one side of the air duct. The air change wheel assembly 9 is prior art and will not be described in detail.

[0021] The blowing wheel assembly 3 comprises a fan chamber 31 , in which a fan 32 is arranged.

[0022] A lighting assembly is provided in the air guide cone 7 , and the lighting assembly is a prior art and will not be described in detail.

[0023] When in use, the blowing wheel assembly 3 blows cold air into the air duct, and the heating sheets 8 are arranged at intervals. The heating sheets 8 are made of mica sheets and graphene coatings, which quickly heat the cold air, shorten the preheating time, and improve the heating efficiency. The gap size can be set according to needs, which can reduce wind resistance and noise. The wind guide cone 7 guides the hot air to flow in a streamlined manner, reduces wind resistance, and reduces noise. The heated air is finally discharged through the air outlet 6. The overall structure is simple.

[0024] The above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
