Description

Technical Field

[0001] The utility model relates to the field of household heating equipment, in particular to a fan heater. Background Art

[0002] The design of traditional chassis equipment, such as heaters, is becoming more and more user-friendly. When the user operates the heater, the indicator light displays the signal of each function. In order to facilitate user operation, touch buttons and display lights are generally set on the top of the chassis equipment. The top of the chassis equipment is usually assembled by splicing multiple parts. When the top cover of the chassis equipment in the prior art is arc-shaped, the splicing gap of the arc-shaped splicing parts of each parts is large, which affects the overall appearance of the chassis equipment.

[0003] In addition, the chassis equipment in the prior art usually uses screws to directly pass through the top cover outside to fix the top cover and the outer shell. This splicing method not only has a large splicing gap, but also the screws are exposed on the top, resulting in poor aesthetics of the entire machine. In addition, since the screws are metal parts, over time, the screws will corrode other parts, causing the screws to loosen or even fall off, thereby affecting the strength of the entire chassis equipment.

In other embodiments, the mounting post 142 with a screw hole 1422 provided therein can also be provided on the mainboard bracket 30, and the lug 342 with a through hole 3422 provided therein can also be provided on the front panel 14, and the screw can be passed through the through hole 3422 and screwed into the screw hole 1422 to fix the mainboard bracket 30 to the bottom of the top panel 12.

[0039] The mainboard 20 is provided with a touch spring 24 and a function indicator light 25 for controlling the function of the heater 100. Correspondingly, a guide column 326 and a lamp hole 327 are provided on the mainboard bracket 30. A guide hole 3262 is provided in the guide column 326. The mainboard 20 is installed at the bottom of the mainboard bracket 30, and its touch spring 24 passes through the guide hole 3262, and the indicator light 25 is inserted into the lamp hole 327. The top plate 12 of the housing 10 is provided with a key hole 120 and an indicator light slot 121. After the mainboard assembly 50 is installed to the housing 10, the touch spring 24 is exposed on the upper surface of the housing top plate 12 by means of the key hole 120, and the indicator light emitted by the indicator light 25 is emitted to the outside from the position of the indicator light slot 121. In this embodiment, the cover plate 42 of the top cover 40 is also provided with a control window 420 for controlling the touch spring 24 and displaying the indicator light of the indicator light 25. When the top cover 42 and the housing 10 are installed with each other, the touch spring 24 and the indicator light 25 are located at the bottom of the control window 420.

[0040] The beneficial effects of the technical improvement of the present utility model are further illustrated below through an installation embodiment of the housing 10 of the heater 100, the top cover 40, the main board 20 of the main board assembly 50, and the main board bracket 30.

[0041] First, the touch spring 24 and the indicator light 25 of the mainboard 20 are respectively inserted into the guide hole 3262 and the indicator light slot 121 of the mainboard bracket 30 , thereby forming the mainboard assembly 50 .

[0042] Then, the motherboard assembly 50 is installed into the housing 10. Specifically, the motherboard assembly 50 is placed at the bottom of the top plate 12 of the housing 10, the positioning column 124 of the top plate 12 is inserted into the through hole 3622 of the motherboard bracket 30, and the card edge 122 of the top plate 12 is embedded in the card slot 322 at the bottom of the top plate 12. After the motherboard assembly 50 is positioned as described above, the motherboard assembly 50 is further fixed to the bottom of the top plate 12 by screws passing through the through hole 3422 of the motherboard bracket 30 and the screw hole 1422 of the front plate 14. After the motherboard assembly 50 is fixed, the touch spring 24 of the motherboard assembly 50 passes through and exposes the key hole 120 of the top plate 12, and the indicator light 25 is placed in the indicator light slot 121. This arrangement of allowing the touch spring 24 to pass through and expose the key hole 120 of the top plate 12 can ensure that the touch spring 24 is closer to the surface of the top cover 40, so that the operator can operate the touch spring 24 from the surface of the top cover 40. The indicator light 25 is placed in the indicator light slot 121, so that the light of the indicator light 25 is limited to be emitted from the top of the indicator light slot 121, thereby preventing the light of the indicator light 25 from escaping and affecting the performance of the product.

[0043] Next, the rear cover of the housing 10 is installed. In this embodiment, after the rear cover is installed, the top of the front plate 14 of the housing 10 of the heater 100 is provided with a bearing space 146 that is recessed inward relative to the front plate front 145, and the top of the rear cover is provided with a bearing space with the same structure as the bearing space 146. The overall cross-sectional structure of the top of the housing 10 is a symmetrical structure.

[0044] Finally, the panels 44 at both ends of the top cover 40 are respectively placed in the bearing spaces 146 at the top of the front plate 14 and the rear cover, so that the limiting ribs 446 at the bottom of the panels 44 are embedded in the limiting notches 145 at the edge of the top surface 144 of the front plate, and the first hooks 141 at the top surface 144 of the front plate and the second hooks 442 on the inner wall of the panels 44 of the top cover 40 abut against each other and snap together. The assembly process of the rear cover is similar. The limiting ribs 446 at the bottom of the top cover panels 44 are embedded in the limiting notches 145 at the edge of the top surface 144 of the front plate, so as to further fix the top cover 40 and the housing 10. By embedding the limiting ribs 446 into the limiting notches 145, the splicing line where the top cover 40, the front plate 14 and the rear cover meet is significantly narrowed, which can avoid the situation where the gap difference caused by the traditional heater fixing method of screw holes and screws leads to obvious splicing marks. In addition, by interlocking the first hook 141 provided on the outer shell 10 and the second hook 442 on the inner wall of the top cover panel 44, the gap between the top cover 40 and the outer shell 10 is not obvious, and it can also ensure that the top cover 40 is tightly attached to the outer shell 10 and the top of the back cover, thereby greatly improving the aesthetics of the entire product.

[0045] After installing the top cover 40, the touch spring 24 and the indicator light 25 are located at the bottom of the control window 420. The user can control the operation of the heater 100 through the control window 420 of the top cover 40 corresponding to the position of the touch spring 24 at the top of the heater 100, and observe the indicator light 25 in the control window 420 to display the corresponding function.

[0046] The utility model provides a heater 100, which provides a structure in which an arc-shaped top cover 40 is spliced ​​and installed with a housing 10, which ensures the integrity of the arc-shaped top of the heater 100 while avoiding obvious installation marks on the appearance, and the connection structure of the top cover 400 is simple, and the installation operation is convenient. In addition, the functions of the touch spring 24 and the indicator light 25 on the top of the heater 100 can be ensured, and the overall appearance of the heater 100 is highly consistent.
