Description

Technical Field

[0001] This utility model relates to the field of bathroom heaters, and specifically to a novel bathroom heater. Background Technology

[0002] In existing bathroom heater technology, the structural design of the heating element often has room for optimization. Traditional PTC heating elements typically have a simple flat shell structure, which affects heating efficiency. Furthermore, the installation and maintenance of the wiring module are not convenient, and the wiring cover often uses a single screw for fixing, resulting in cumbersome installation. Therefore, there is an urgent need for a new type of bathroom heater with improved structure to solve these technical problems. Utility Model Content

[0003] This utility model provides a new type of bathroom heater to solve the problems of the prior art.

[0004] The objective of this utility model can be achieved through the following technical solution: A novel bathroom heater includes a main unit and a cover plate. The cover plate is disposed on the upper end of the main unit. The main unit includes a housing, an air intake component, an exhaust component, and a PTC heating component disposed inside the housing. The air intake component draws in indoor air, heats it through the PTC heating component, and then blows it out into the room. The exhaust component discharges indoor air to the outside. The PTC heating component includes a housing and a PTC module. The PTC module is disposed inside the housing. The housing is installed on the inner side of the cover plate. The width of the housing cross-section decreases upwards at both ends. The end face of the housing is provided with staggered reinforcing ribs. The middle part of the cover plate is provided with a mesh cover with baffles corresponding to the air intake component and the exhaust component. The rear side of the middle part of the cover plate is provided with a cavity for accommodating a wiring module. A wire outlet cover is fastened to the outside of the cavity. The wire outlet cover is provided with wire outlet holes at both ends.

[0005] In a further improvement, the depth of the reinforcing rib along the inner direction of the shell is 20mm~25mm, and the lower end of the reinforcing rib is tapered along the inner direction of the shell.

[0006] In a further improvement, the bottom side of the housing is a circular arc guide surface, which is located outside the air duct on one side of the exhaust assembly.

[0007] In a further improvement, the front end of the cable outlet cover is provided with three sets of inserts, which are inserted into the groove on the front side of the cavity. The rear end of the cable outlet cover is provided with two sets of buckles, which are fastened into the groove on the rear side of the cavity. The middle part of the cable outlet cover is fixedly connected to the screw post inside the cavity by a set of screws.

[0008] In a further improvement, both the intake and exhaust assemblies include a fan and blades.

[0009] Compared with existing technologies, the beneficial effects of this novel bathroom heater are as follows:

[0010] The PTC heating element's housing features a cross-section design that is narrower at the top and wider at the bottom, combined with staggered reinforcing ribs, which reduces airflow resistance and enhances heat exchange efficiency. The mesh cover with baffles overcomes the shortcomings of traditional open designs that allow foreign objects to enter, forming a physical barrier to ensure the safe operation of the intake and exhaust components. The wiring cover abandons the traditional screw fixing method, achieving quick snap-fit ​​through inserts and clips, simplifying the installation process. At the same time, the wiring holes on both sides break through the limitations of wiring direction, allowing users to flexibly arrange the wiring according to actual needs, improving the convenience and practicality of bathroom heater installation.

[0017] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0018] Example 1

[0019] A novel bathroom heater includes: a main unit 1 and a cover plate 2, the cover plate 2 being disposed on the upper end of the main unit 1. The main unit 1 includes a housing 11, an air intake assembly 12, an exhaust assembly 13, and a PTC heating assembly 14 disposed inside the housing 1. The air intake assembly 12 draws in indoor air, heats it through the PTC heating assembly 14, and then blows it out into the room. The exhaust assembly 13 exhausts indoor air to the outside. The PTC heating assembly 14 includes a housing 141 and a PTC module 142. Module 142 is disposed inside housing 141, housing 141 is installed inside cover plate 2, the width of housing 141 decreases upward at both ends of the cross section, and staggered reinforcing ribs 143 are provided on the end face of housing 141. The upper middle part of cover plate 2 is provided with a mesh cover 15 with baffle strips corresponding to air intake assembly 12 and exhaust assembly 13. The rear side of the middle part of cover plate 2 is provided with cavity 21 for accommodating wiring module. Outlet cover 3 is fastened to the outside of cavity 21. Outlet cover 3 is provided with outlet holes 31 at both ends of outlet cover 3.

[0020] like Figures 1-4 As shown, the principle of this utility model is as follows:

[0021] The air intake and exhaust components inside the main unit are centered around a fan and blades, which draw in or expel indoor air through rotation. When the intake air passes through the PTC heating component, the PTC module converts electrical energy into heat energy to heat the air before sending it back into the room to raise the temperature; the exhaust component simultaneously expels humid air to the outside.

[0022] The housing of the PTC heating element is installed inside the cover plate. Its cross-section is narrow at the top and wide at the bottom, which can guide the airflow evenly through the heating area and reduce flow resistance. The staggered reinforcing ribs not only enhance the strength of the housing, but also disturb the airflow and promote heat exchange.

[0023] Traditional open-style mesh covers with baffles cannot prevent foreign objects from entering. During the installation of a bathroom heater / ventilation unit, power cords, plugs, and other items can easily fall into the air intake or exhaust components, potentially becoming entangled in the fan blades and causing damage or malfunction. This mesh cover with baffles forms a physical barrier, effectively preventing interference from foreign objects during installation, ensuring the normal operation of the air intake and exhaust components, and reducing the risk of malfunction.

[0024] Traditional cable outlet covers are mostly fixed with screws, which requires precise alignment and repeated tightening of screws during installation, making the operation time-consuming. This cable outlet cover uses inserts and clips to cooperate with the grooves in the cover plate cavity, achieving quick snap-fit ​​installation, reducing installation steps, and can be disassembled and assembled without tools.

[0025] Traditional bathroom heaters have fixed cable outlet positions, limiting the direction of cable routing and potentially requiring cable bends in complex wiring scenarios. This cable outlet cover features outlet holes on both sides, breaking the limitation of a single cable routing direction. Installers can flexibly choose the cable outlet position according to actual needs, achieving a more rational wiring layout.

[0026] As a further preferred embodiment, the reinforcing rib 143 has a depth of 20mm~25mm along the internal direction of the housing 141, and the lower end of the reinforcing rib 143 has a taper along the internal direction of the housing 141. Traditional PTC heating element housing reinforcing ribs are relatively shallow, at 16mm, which limits their guiding and accelerating effect on airflow, resulting in a short air outlet distance and small coverage area. This embodiment increases the depth of the reinforcing rib to 20mm-25mm, enhancing the guiding and accelerating effect on airflow through a deeper three-dimensional structure, thus increasing the air outlet distance compared to traditional designs.

[0027] As a further preferred embodiment, the bottom side of the housing 11 is a circular arc guide surface 19, which is located outside the air duct 18 on one side of the exhaust assembly 13. Traditional bathroom heater exhaust ducts often have right angles or planar structures on the outside, which easily create turbulence at the corners, increasing exhaust resistance. This embodiment utilizes the smooth transition characteristics of a circular arc to guide airflow smoothly through the corner area of ​​the air duct, reducing pressure loss.

[0028] As a further preferred embodiment, the front end of the cable outlet cover 3 is provided with three sets of inserts 32, which are inserted into the grooves on the front side of the cavity 21. The rear end of the cable outlet cover 3 is provided with two sets of latches 33, which are latched into the grooves 221 on the rear side of the cavity 21. The middle part of the cable outlet cover 3 is fixedly connected to the screw post 222 inside the cavity 21 by a set of screws. In this embodiment, the inserts at the front end of the cable outlet cover cooperate with the grooves on the front side of the cavity, the latches at the rear end are latched into the grooves on the rear side of the cavity, and the screws in the middle are connected to the screw post inside the cavity, forming a rigid connection. Compared with a single latch, the connection is more stable and only requires one set of screws for fixation, which is less time-consuming.

[0029] As a further preferred embodiment, both the intake assembly 12 and the exhaust assembly 13 include a fan wheel 16 and blades 17.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
