Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and more specifically, to a bathroom heater. Background Technology

[0002] Currently, bathroom heaters are essential equipment in winter bathroom environments, with their core function being to raise indoor temperature by heating the air. In existing technology, the PTC heating element in heaters is mostly installed on a plastic component using screws. However, this traditional fixing method has significant drawbacks: First, the screw installation process is cumbersome, increasing labor costs; second, the screws can easily cause stress damage to the plastic component during tightening, leading to cracking or deformation and affecting product lifespan; furthermore, the screw-fixed structure limits the size and shape of the PTC heating element, making it difficult to adapt to customers' needs for diversified and customized products.

[0003] Some products on the market attempt to alleviate the above problems by improving the fixing structure, such as using clips or adhesives. However, these methods still suffer from issues such as insecure installation, difficulty in disassembly, or insufficient high-temperature resistance. Especially in the high humidity and temperature fluctuations of a bathroom, plastic parts are prone to aging, further exacerbating the reliability risks of the fixing structure. Therefore, designing a PTC heating element fixing solution that is easy to install, structurally stable, and highly adaptable has become a pressing technical challenge in this field.

[0004] Based on this, this application proposes a new type of bathroom heater, which aims to completely eliminate the screw fixing method through innovative fixed component design, while improving the flexibility and durability of the product, so as to meet the higher requirements of modern bathroom environment for heating equipment.

[0031] Please see Figure 1-7 The bathroom heater includes a housing 1 and a cover 2. The housing 1 has a first chamber 101. The cover 2 has a first air inlet 201 corresponding to the first chamber 101. A blower assembly 3 is installed in the first chamber 101. The blower assembly 3 includes a blower impeller 4, a blower motor 5, an air outlet assembly 6, and a fixing assembly 7. The blower impeller 4 is mounted on the motor shaft of the blower motor 5 and is correspondingly positioned to the first air inlet 201. The air outlet assembly 6 includes an air guide duct 60. 1 and PTC heating element 602, air duct 601 includes air inlet end 6011 and air outlet end 6012, air outlet groove 202 is opened on cover plate 2, air outlet end 6012 is installed at air outlet groove 202, fixing component 7 is installed on air inlet end 6011 of air duct 601, including material rack 701 and plug 702, plug 702 has a limiting groove 7021 on one side and a snap-fit ​​protrusion 7022 on the other side, and snap-fit ​​groove 7011 is opened on material rack 701.

[0032] In specific applications, the PTC heating element 602 is installed in the limiting groove 7021 of the plug 702. The plug 702 corresponds to the limiting protrusion 7012 located inside the material rack 701 and is inserted into the material rack 701. During the insertion process, the metal material rack 701 undergoes slight elastic deformation to allow the snap-fit ​​protrusion 7022 to smoothly enter the material rack 701, so that the snap-fit ​​protrusion 7022 on the plug 702 is located in the snap-fit ​​groove 7011 of the material rack 701, thereby realizing the installation and fixation of the PTC heating element 602.

[0033] In use, the blower motor 5 drives the blower impeller 4 to rotate, drawing air from outside the housing 1 into the first chamber 101 through the first air inlet 201. After being heated by the PTC heating element 602 in the material rack 701, the air enters the air guide 601 and is finally discharged back out of the housing 1 through the air outlet 6012 of the air guide 601 and the air outlet slot 202 on the cover plate 2, thus completing the heating of the air.

[0034] In practice, depending on the different thicknesses of the PTC heating element 602, inserts 702 with different sized limiting grooves 7021 can be manufactured to match PTC heating elements 602 of different sizes.

[0035] In this embodiment, the housing 1 also has a second chamber 102. The cover plate 2 has a second air inlet 203 corresponding to the second chamber 102. The second chamber 102 is equipped with a ventilation assembly 8, which includes a ventilation impeller 801 and a ventilation motor 802. The ventilation impeller 801 is mounted on the motor shaft of the ventilation motor 802. The ventilation motor 802 is used to drive the ventilation impeller 801 to rotate. The housing 1 has an air outlet 103 on one side that communicates with the second chamber 102. The air outlet 103 communicates with the outdoor air and is used to deliver indoor air to the outside.

[0036] When in use, the ventilation motor 802 drives the ventilation fan 801 to rotate, drawing air from outside the housing 1 into the second chamber 102 through the second air inlet 203, and discharging it through the air outlet 103 connected to the second chamber 102. The air outlet 103 can be connected to the outside through a pipe to deliver indoor air to the outside and complete the ventilation.

[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
