Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a lifting mechanism and a toaster. Background Technology

[0002] A bread toaster is available for baking sliced ​​bread, comprising a housing, a bracket, and a handle assembly. The housing contains a baking cavity, and the bracket is movably disposed within the baking cavity. One end of the bracket extends out of the baking cavity and connects to the handle assembly. The handle assembly has a first engaging portion with a spring abutting against the housing and the handle. The housing has a locking mechanism located below the handle assembly, comprising a latch and a movable block. The latch has an electromagnet, and the movable block has a magnetic element and a second engaging portion. The movable block is mounted on the latch and can rotate relative to the latch. During operation, bread is placed in the baking cavity, supported by the bracket. Manually driving the handle assembly downwards until the first engaging portion engages upwards with the second engaging portion. Simultaneously, manually driving the handle assembly triggers the electromagnet's power switch, causing the electromagnet and magnetic element to attract each other, thus fixing the movable block to the latch. The first and second fastening parts remain engaged. When the bread toaster finishes working, the control circuit de-energizes the electromagnet, releasing the magnetic constraint of the movable block. Under the action of the first fastening part, the movable block flips, causing the first fastening part to disengage from the second fastening part. The spring drives the handle assembly to move upward, and the tray pushes the bread out. However, in existing bread toasters, very little bread is exposed after being pushed out, posing a risk of burns when the user touches the opening of the baking cavity. Therefore, it is necessary to increase the height of the tray to solve this problem. Since one end of the tray is connected to the handle assembly, increasing the height of the tray will inevitably increase the travel of the handle assembly, increasing the burden on the user. Therefore, it is necessary to design a bread toaster that increases the push-out travel of the tray without increasing the travel of the handle assembly. Utility Model Content

[0020] Below, in conjunction with Figures 1 to 9 The present invention will be further described in the preferred embodiments and other embodiments. It should be noted that, without conflict, the technical features described below can be arbitrarily combined to form new embodiments.

[0021] This utility model provides a toaster oven. Figures 1-6The diagram shows a preferred embodiment of the toaster of this utility model. In this embodiment, the toaster has a baking cavity 20, a bracket 7, and a lifting mechanism 10. The lifting mechanism 10 includes a fixed frame 1 and a stroke amplification mechanism. The fixed frame 1 includes a first sliding rod 11 arranged vertically and a second sliding rod 12 arranged parallel to the first sliding rod 11. The stroke amplification mechanism includes a first pulley assembly 2, a first force balance maintaining mechanism 3, a second force balance maintaining mechanism 4, a first sliding member 5, and a second sliding member 6. The first sliding member 5 is disposed on the first sliding rod 11 and can slide vertically along the first sliding rod 11. The second sliding member 6 is disposed on the second sliding rod 12 and can slide vertically along the second sliding rod 12. The first pulley assembly 2 includes a first pull rope 21 and a first movable pulley 22. The first movable pulley 22 is disposed on the first sliding member 5. The first end of the first pull rope 21 is fixed to the fixed frame 1, and the second end of the first pull rope 21 passes around the first movable pulley 22 and connects to the first sliding member 5. Two sliding members 6, under the action of the first pulley assembly 2, the first sliding member 5 and the second sliding member 6 can move in the same direction relative to the fixed frame 1. The first force balance maintaining mechanism 3 provides an upward force to the first sliding member 5, that is, the first force balance maintaining mechanism 3 applies a force to the first sliding member 5 in the opposite direction of the weight of the first sliding member 5 to maintain the force balance of the first sliding member 5 and prevent it from losing weight and falling down. The second force balance maintaining mechanism 4 provides an upward force to the second sliding member 6, that is, the second force balance maintaining mechanism 4 applies a force to the second sliding member 6 in the opposite direction of the weight of the second sliding member 6 to maintain the force balance of the second sliding member 6 and prevent it from losing weight and falling down. The lifting mechanism 10 is provided outside the baking cavity 20. The fixed frame 1 is fixed relative to the baking cavity 20. The bracket 7 is movably provided inside the baking cavity 20.

Under the action of the first pulley assembly 2 and the second force balance maintaining mechanism 4, the second sliding member 6 moves higher, thereby amplifying the stroke of the second sliding member 6 relative to the first sliding member 5. When the toaster finishes toasting the bread, the first force balance maintaining mechanism 3 drives the first sliding member 5 to move upward, and then the stroke amplification mechanism drives the bracket 7, so that the bracket 7 rises higher relative to the handle 8, pushing the toasted bread further away from the toasting cavity 20 for easy removal by the user and avoiding burns. Since the bracket 7 is reset by using the stroke amplification mechanism, it is easier to meet the requirements of safety certification: that is, the toasted bread slices remain in the toaster for less than 60mm, and the bread slices protrude more than 20mm from the toaster opening, making it easier for consumers to pick up the bread slices.

[0022] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment, the first force balance maintaining mechanism 3 includes a first elastic drive member 31. The first elastic drive member 31 provides an upward elastic force to the first sliding member 5. Specifically, the first elastic drive member 31 is located below the first movable pulley 22 and abuts against the first sliding member 5 and the fixed frame 1. In this embodiment, the first elastic drive member 31 is a compression spring. When the toaster completes the bread baking work, the toaster control system controls the relevant mechanism to release the elastic constraint on the first elastic drive member 31. The first elastic drive member 31 pushes the first sliding member 5 upward to move upward, and then drives the bracket 7 upward through the stroke amplification mechanism to push the baked bread further away from the baking cavity 20. In other embodiments, the first elastic drive member 31 is located above the first movable pulley 22.

In this embodiment, the first elastic drive member 31 is a tension spring. When the toaster finishes baking bread, the toaster control system controls the relevant mechanism to release the elastic constraint on the first elastic drive member 31. The first elastic drive member 31 pulls the first sliding member 5 upward and moves it upward.

The third fixed pulley 43 is located below the second movable pulley 42, and the fourth fixed pulley 44 is located above the second movable pulley 42. The first end of the second pull rope 41 is located at the... Below the second movable pulley 42, the second end of the second pull rope 41 passes sequentially around the second movable pulley 42, the third fixed pulley 43, and the fourth fixed pulley 44 before being fixed to the second sliding member 6; when the first sliding member 5 is driven upward, the first pulley assembly 2 does not act on the first sliding member 5 and the second sliding member 6, the first sliding member 5 drives the second pulley assembly 4a, and then the second pulley assembly 4a pulls the second sliding member 6 upward to drive it to move upward, thereby driving the bracket 7 to rise to push out the bread; Figure 5 As shown, when the first slider 5 is driven downward, the second pulley assembly 4a does not act on the first slider 5 and the second slider 6. The first slider 5 drives the first pulley assembly 2, and then the first pulley assembly 2 pulls the second slider 6 downward, thereby driving the bracket 7 to descend so as to send the bread into the baking cavity 20.

[0024] refer to Figure 2 and Figure 4In a preferred embodiment, when projected along the vertical direction, the projections of the first movable pulley 22, the first fixed pulley 23, and the second fixed pulley 24 are all aligned radially along the first movable pulley 22; the first movable pulley 22 and the second movable pulley 42 are arranged side by side along the axial direction of the first movable pulley 22, and when projected along the vertical direction, the projections of the second movable pulley 42, the third fixed pulley 43, and the fourth fixed pulley 44 are all aligned radially along the first movable pulley 22, thus avoiding mutual interference between the windings of the first pull rope 21 and the second pull rope 41.

[0025] like Figure 4 As shown, in a preferred embodiment, the projections of the first sliding member 5 and the second sliding member 6, projected along the vertical direction, are both centered along a central axis L. The central axis L is radially parallel to the first sliding wheel 22. Two second sliding rods 12 are symmetrically distributed along the central axis L to make the sliding of the first sliding member 5 more stable. In this embodiment, one first sliding rod 11 is provided and centered along the central axis L, and the first sliding member 5 is simultaneously slidably connected to both the first sliding rod 11 and one of the second sliding rods 12.

[0026] In other embodiments, such as Figure 7 As shown, the difference between this and the preferred embodiment lies in the different arrangements of the first sliding rod 11 and the second sliding rod 12. Specifically, both the first sliding rod 11 and the second sliding rod 12 are provided and are centered along the central axis L. The first sliding member 5 is slidably connected to both the first sliding rod 11 and the second sliding rod 12, and the second sliding member 6 is slidably connected to both the first sliding rod 11 and the second sliding rod 12.

[0028] In other embodiments of the second type, such as Figure 8 and Figure 9As shown, the difference between this and the preferred embodiment lies in the structure of the second force balance maintaining mechanism 4 and the arrangement of the first sliding rod 11 and the second sliding rod 12. Specifically, the structure of the second force balance maintaining mechanism 4 is as follows: the first end of the first pull rope 21 is located above the first movable pulley 22; the first force balance maintaining mechanism 3 includes a first elastic drive member 31, which provides an upward elastic force to the first sliding member 5; the second force balance maintaining mechanism 4 includes a second elastic drive member 4b, which provides an upward elastic force to the second sliding member 6. When the first sliding member 5 is driven upward, the first pulley assembly 2 does not act on the first sliding member 5 and the second sliding member 6. Simultaneously, the second elastic drive member 4b drives the second sliding member 6 upward, thereby driving the bracket 7 to rise and push the bread out. When the first sliding member 5 is driven downward, the first sliding member 5 drives the first pulley assembly 2 via the second fixed pulley 24. The first pulley assembly 2 then pulls the second sliding member 6 downward to overcome the elastic force of the second elastic drive member 4b and move downward, thereby driving the bracket 7 to descend and feed the bread into the baking cavity 20. In this embodiment, the first elastic drive member 31 and the second elastic drive member 4b are located on the same side of the first movable pulley 22. Specifically, the first elastic drive member 31 and the second elastic drive member 4b are both located above the first movable pulley 22. The first elastic drive member 31 is fixed to the fixed frame 1 and lifts the first sliding member 5 upwards, while the second elastic drive member 4b is fixed to the fixed frame 1 and lifts the second sliding member 6 upwards. In other embodiments, the first elastic drive member 31 and the second elastic drive member 4b are both located below the first movable pulley 22. The first elastic drive member 31 abuts against the first sliding member 5 and the fixed frame 1, while the second elastic drive member 4b abuts against the second sliding member 6 and the fixed frame 1. In this embodiment, the arrangement of the first sliding rod 11 and the second sliding rod 12 differs from that in the preferred embodiment in that there are two of each. Specifically, there are two second sliding rods 12 symmetrically distributed along the central axis L, and two first sliding rods 11 symmetrically distributed along the central axis L.

[0029] The beneficial effects of the technical solution of this utility model are as follows: by setting the first movable pulley on the first sliding member, fixing the first end of the first pull rope to the fixed frame, and connecting the second end of the first pull rope to the second sliding member after passing around the first movable pulley, the first sliding member is driven upward, and the second sliding member moves higher upward under the action of the first pulley assembly and the second force balance maintaining mechanism, so as to realize the amplification of the stroke of the second sliding member relative to the first sliding member.
