Description

Technical Field

[0001] The utility model relates to the technical field of toaster switches, in particular to a toaster switch with a compact structure. Background Art

[0002] A toaster is an electric cooker specially used for re-toasting sliced ​​bread.

[0003] In the prior art, a toaster switch includes a base, a start-stop assembly and a locking assembly. The start-stop assembly and the base are connected by a plurality of guide rods. The start-stop assembly rises and falls relative to the base along the guide rods. The locking assembly includes an electromagnet, an armature and a flip bracket for fixing the armature. The flip bracket is hinged to the base and can be flipped and fixed to the base through the magnetic attraction between the electromagnet and the armature. When the electromagnet is energized, the flip bracket is fixed to the base. When the electromagnet is de-energized, the flip bracket can flip freely relative to each other. However, this structure has the following disadvantages: (1) The overall size of the switch is large: the base needs to be processed with ribs that cooperate with the flip bracket and space for installing the flip bracket; (2) A large space needs to be reserved on the toaster to avoid the flipping activity of the flip bracket, which is not conducive to the miniaturization design of the toaster.

[0037] The following is a detailed explanation of the implementation of the present invention in conjunction with the accompanying drawings. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention.

[0038] See also Figure 1-Figure 4 In this embodiment, a compact toaster switch includes:

[0039] The base 1 is provided with a first switch 11 and a second switch 12;

[0040] A driving slider 4, used to turn on the first switch 11 or the second switch 12;

[0041] The start-stop assembly 2 is provided with a barb 21 extending downward and fixed on the start-up driving handle of the toaster machine; when the start-stop assembly 2 is pressed down toward the end close to the base 1 along with the start-up driving handle of the toaster machine, the driving slider 4 turns on the contact points of the first switch 11 and the second switch 12;

[0042] The locking assembly 3 includes an electromagnet 31 and an armature piece 32. The electromagnet 31 is arranged on the base 1. The connecting end of the armature piece 32 is rotatably matched with the base 1, and the locking end is provided with a locking hook 322 that cooperates with the barb 21; the armature piece 32 is freely stacked on the top of the electromagnet 31.

[0043] In this embodiment, in the heating circuit of the toaster, the live wire of the heating element (heating wire) is electrically connected to the power supply through the first switch 11, and the neutral wire thereof is electrically connected to the power supply through the electric wire and the second switch 12, thereby realizing bipolar switching; the start-stop component 2 of this embodiment is a block-shaped body, and the block body and the toaster slide in the vertical direction. A handle extends outward from the outer side of the block body. When the user applies force downward on the handle, the start-stop component 2 slides toward the end close to the base 1 and acts on the first switch 11 and the second switch 12 at the same time, and the heating circuit of the toaster forms an electrical path, and the heating element starts to work; this embodiment also includes a delay control circuit: the electromagnet 31 When powered on, the electromagnet 31 magnetically cooperates with the armature piece 32 to fix it on the base 1. At this time, the lock hook 322 cooperates with the barb 21 to provide a locking force for the start-stop component 2 to maintain the current position, thereby allowing the toaster to heat within the preset time of the delay control circuit; when the electromagnet 31 is powered off, the electromagnet 31 cancels the magnetic attraction force on the armature piece 32. At this time, the armature piece 32 can flip relative to the base 1, and the elastic force of the elastic member (not shown in the figure) is used to provide an elastic force for the start-stop component 2 to move upward, so that the contacts of the first switch 11 and the second switch 12 are disconnected, thereby causing the toaster to stop heating after the preset time of the delay control circuit is reached.

[0044] Preferably, a rotating shaft 321 is provided at the connecting end of the armature piece 32 extending outwardly, and a rotating shaft positioning device 13 is provided on the base 1 , and the rotating shaft 321 is rotatably matched with the rotating shaft positioning device 13 .

[0045] The cam 321 is provided with a plurality of holes for holding the cam 322 in place so that the cam 322 can be easily locked.

[0046] Preferably, the rotating shaft 321 is integrally formed at the connecting end of the armature piece 32 , and the locking hook 322 is integrally formed at the locking end of the armature piece 32 .

[0047] In this embodiment, the armature piece 32 body, the rotating shaft 321 and the barb 21 can be formed at one time by injecting molten metal into a die-casting mold, thereby further simplifying the processing technology.

[0048] Furthermore, a support sheet 14 is provided on the base 1 , and the support sheet 14 matches the thickness of the electromagnet 31 and can provide an upward supporting force for the armature sheet 32 ​​.

[0049] In this embodiment, there are two support sheets 14, which are respectively arranged on both sides of the electromagnet 31, and the heights of the two support sheets 14 are flush with the top of the electromagnet 31. On the one hand, they play the role of supporting the armature sheet 32. On the other hand, at the moment when the electromagnet 31 is powered off, the start-stop assembly 2 is subjected to the elastic force of the elastic member (not shown in the figure) to drive the hook 21 upward for a distance, and the lock hook 322 on the armature sheet 32 ​​is pulled upward by the hook 21. After the armature sheet 32 ​​is flipped at a certain angle relative to the base 1, it falls freely on the electromagnet 31. Long-term use will cause the armature sheet 32 ​​to The deviation in flatness between the center and the two side portions may easily leave a gap between the center of the armature piece 32 and the top of the electromagnet 31, thereby reducing the area of ​​magnetic attraction between the armature piece 32 and the electromagnet 31. In addition, because in the locked heating state, the start-stop component 2 is subjected to the upward elastic driving force of the elastic member (not shown in the figure), the heating cannot be locked. In this embodiment, a pair of support plates 14 are used to act on the armature piece 32, so that the bottom surface of the body is more evenly stressed when it falls freely, which is beneficial to reduce the occurrence of the start-stop component 2 bouncing up before the preset time, and to increase the service life of the armature piece 32.

[0050] Preferably, it also includes:

[0051] An elastic member (not shown in the figure) is provided on the base 1, acts on the driving slider 4, and can continuously provide elastic force for the driving slider 4 to slide upward; the driving slider 4 is slidably connected to the base 1 in the vertical direction;

[0052] When the start-stop assembly 2 is pressed down toward one end close to the base 1, it squeezes and drives the driving slider 4 to slide downward. At this time, the elastic member (not shown in the figure) is compressed, and the driving slider 4 can make the contacts of the first switch 11 and the second switch 12 conductive at the same time.

[0053] In this embodiment, the base 1 is provided with a circular sleeve between the first switch 11 and the second switch 12, and the elastic member (not shown in the figure) is a spring arranged in the circular sleeve. The driving slider 4 is provided with a circular columnar body extending downward, and the circular columnar body is coaxially sleeved in the circular sleeve. The bottom end of the spring is against the bottom of the circular sleeve, and the top end is against the circular columnar body. When the start-stop component 2 is pressed down toward one end close to the base 1, it squeezes and drives the driving slider 4 to slide downward. At this time, the elastic member (not shown in the figure) is compressed, and the driving slider 4 can make the contacts of the first switch 11 and the second switch 12 conductive at the same time. At the same time, the electromagnet 31 is energized to cooperate with the armature piece 32 by magnetic attraction, and the locking hook 322 on the armature piece 32 is used to engage with the start-stop component The barb 21 on the member 2 cooperates to provide a force for the driving slider 4 to maintain the current height; when the preset time of the delay control circuit is reached, the electromagnet 31 cancels the magnetic attraction of the armature piece 32, and the elastic member (not shown in the figure) is released to push the driving slider 4 to move upward relative to the base 1, thereby disconnecting the contacts of the first switch 11 and the second switch 12 at the same time. Compared with the prior art, the elastic parts of the switches in the prior art are all facing the same side, resulting in the need to reserve space in the length direction of the base 1 for the elastic parts of the switches to restore to a natural state.
