Description

Technical Field

[0001] This utility model relates to the field of bathroom heaters, and specifically to a combined heating block structure for a bathroom heater. Background Technology

[0002] A bathroom heater is a household appliance installed in a bathroom to provide multiple functions such as heating, lighting, and ventilation. The core component inside a bathroom heater is usually a PTC ceramic heating element. This material increases its resistance and heats up when electricity is applied, converting electrical energy into heat energy, which is then dissipated to the outside. However, the PTC heating element inside a bathroom heater typically has two or three power levels, with the specific power values ​​varying depending on the brand and model. The relatively fixed combination of these power levels results in a limited range of power settings.

[0003] Therefore, in order to overcome the shortcomings of the existing technology, it is necessary to design a simple structure for the combined heating block of a bathroom heater. Utility Model Content

[0006] In a further improvement, the full-section PTC heating element has several groups in the middle, and the segmented PTC heating element has one group, which is located outside one group of the outermost full-section PTC heating elements.

[0007] In a further improvement, the full-section PTC heating element has several groups in the middle, and the segmented PTC heating element has two groups, with the segmented PTC heating elements respectively located on the outermost sides of the two groups of full-section PTC heating elements.

[0008] In a further improvement, the wiring terminal of the long PTC heating element in the segmented PTC heating element is located on the left or right side of the long PTC heating element.

[0009] Compared with the prior art, the beneficial effects of the heating block structure of this utility model bathroom heater combination are as follows:

[0010] The system combines a full-length PTC heating element with segmented PTC heating elements. The segmented PTC heating elements have notches to allow for different power levels. The full-length PTC heating elements and the segmented PTC heating elements of different power levels can be connected individually or in parallel with live wires. The overall size is small. By opening one or more electrically conductive PTC heating element modules, various heating power levels can be obtained through simple wiring arrangements. Attached Figure Description

The segmented PTC heating elements 2 are provided with at least a set of notches 21, through which the segmented PTC heating elements 2 are divided into segments. The full-length PTC heating elements 1 in the middle is provided with a common terminal 3.

[0023] As a further preferred embodiment, the wiring terminal 4 of the long PTC heating element 21 in the segmented PTC heating element 2 is located on the left side or the right side of the long PTC heating element 21.

[0024] The working principle of this utility model is as follows: Figure 1 and Figure 2 For example, there are two sets of full-section PTC heating elements 1 and segmented PTC heating elements 2. The segmented PTC heating elements 2 are located in front of the middle full-section PTC heating element 1. One side of the middle full-section PTC heating element 1 is connected to the common terminal 3 (the common terminal for the neutral wire), and one side of the outer full-section PTC heating element 1 is connected to the terminal (the live wire). The long PTC heating element 22 and the short PTC heating element 23 of the segmented PTC heating element 2 are connected to the terminal (the live wire). The long PTC heating element 22 and the short PTC heating element 23 have different power ratings.

[0025] The long PTC heating element 22 and short PTC heating element 23 of the outer full-length PTC heating element 1 and segmented PTC heating element 2 can be connected to the live wire individually, or any two can be connected in parallel and then connected to the live wire, and the remaining one can be connected to the live wire alone. The wiring method can be selected according to the actual use. The overall size is small. By opening one or more sets of electrically conductive PTC heating element modules, various combinations of heating power levels can be obtained through simple wiring arrangements.

[0026] like Figure 3 and Figure 4For example, there is one set of full-section PTC heating elements 1 and two sets of segmented PTC heating elements 2, located on both sides of the full-section PTC heating element 1 in the middle. One side of the full-section PTC heating element 1 is connected to the common terminal 3 (the common terminal for the neutral wire). The long PTC heating element 22 and the short PTC heating element 23 of the two sets of segmented PTC heating elements 2 are respectively connected to the wiring terminal (connected to the live wire). The long PTC heating element 22 and the short PTC heating element 23 have different power.

[0027] The long PTC heating element 22 and the short PTC heating element 23 of the two-section PTC heating elements 2 can be connected to the live wire individually, or any two can be connected in parallel and then connected to the live wire, or any three can be connected in parallel and then connected to the live wire, and the remaining one can be connected to the live wire alone. The wiring method can be selected according to the actual use. The overall size is small. By opening one or more sets of electrically conductive PTC heating element modules, various combinations of heating power levels can be obtained through simple wiring arrangements.

[0028] 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 many modifications and variations based on the concept of this utility model without creative effort.

Different wiring methods can be used according to actual needs to obtain a variety of heating power levels; and the notches 21 on the segmented PTC heating elements 2 can be provided with two, three, or more, to realize more segmented PTC heating elements 2. The segmented PTC heating elements 2 with multiple notches have multiple small segmented PTC heating elements with different power, further improving the diversity of wiring methods, thereby obtaining more combinations of heating power levels, ensuring a small size while increasing the number of heating power levels.
