[0028] The utility model will be described in further detail below in combination with the drawings.

[0029] Reference Figure 1-6 The toaster of the utility model comprises a frame 500 as shown in the drawings, and a heating assembly installed on the frame 500, wherein the heating assembly comprises a fixed heating unit 100 and a movable heating unit 200 arranged in parallel, and the fixed heating unit 100 and the movable heating unit 200 constitute two side walls of a bread slice slot. Figure 2 In an embodiment, the fixed heating unit 100 is installed at the center of the bottom of the frame 500, and the movable heating unit 200 is movably installed on the side surface of the fixed heating unit 100, and the movable heating unit 200 can make linear motion within a limited distance close to or away from the fixed heating unit 100 according to the needs of a user. In another embodiment, for example, in a small toaster with only one bread slice slot, the fixed heating unit 100 is installed on one side of the bottom of the frame 500, and the movable heating unit 200 is installed on the other side, and when it is necessary to adjust the width of the bread slice slot, the movable heating unit 200 can be made to move close to or away from the fixed heating unit 100.

[0030] The movable heating unit 200 includes a sliding seat 230, a heating plate 210 mounted on the sliding seat 230, and a heat insulation plate 240 covering the outer side of the heating plate 210. Heat dissipation holes 241 are evenly arranged on the heat insulation plate 240 to facilitate the uniform flow of heated air out of the movable heating unit 200. The edges 242 of the heat dissipation holes 241 protrude outward and downward, which can not only reduce the direct contact area between the bread slice and the heat insulation plate 240, but also guide the heated air to flow out in a downward direction, making the heating effect more uniform; at the same time, it prevents the user from accidentally directly contacting the heating plate 210 during use and getting burned.

[0031] In one embodiment, relative movement between the fixed heating unit 100 and the movable heating unit 200 is achieved through the horizontal adjustment assembly 300, that is, the movable heating unit 200 can move back and forth relative to the fixed heating unit 100 or the frame 500 to approach or move away from the fixed heating unit 100.

[0032] A toaster has one or more heating components. In one embodiment, a heating component has a fixed heating unit 100 and two movable heating units 200 located on either side of the fixed heating unit 100 to form two bread slice slots with adjustable widths. Furthermore, the two movable heating units 200 can be moved synchronously by the same horizontal adjustment component 300, that is, they simultaneously approach or move away from the fixed heating unit 100. The two movable heating units 200 can also be controlled separately by their respective horizontal adjustment components 300 to achieve asynchronous movement, that is, they individually approach or move away from the fixed heating unit 100 or maintain a constant distance from the fixed heating unit 100, thereby being able to simultaneously toast bread slices of different thicknesses. In another embodiment, a heating component has a fixed heating unit 100 and a movable heating unit 200 located on either side of the fixed heating unit 100 to form a bread slice slot with adjustable width.

[0033] In one embodiment, Figure 3 、 Figure 4 As shown, the movable heating unit 200 is slidably connected to the horizontal adjustment assembly 300. The movable heating unit 200 includes a heating plate 210 and a baffle 220. The baffle 220 is mounted on both side edges of the heating plate 210. The bottom of the baffle 220 and the bottom of the heating plate 210 are jointly mounted on a sliding base 230. The sliding base 230 is slidably connected to the horizontal adjustment assembly 300.

[0034] In one embodiment, the horizontal adjustment assembly 300 further includes a reset mechanism capable of achieving a reset function. For example, the horizontal adjustment assembly 300 includes a first side plate 310 having a first connection point 311, a baffle 220 having a second connection point 221, and a first compression spring 320 having two ends connected to the first connection point 311 and the second connection point 221, respectively. The first compression spring 320 is horizontally compressed and deformed between the first connection point 311 and the second connection point 221. In another embodiment (not shown), the second connection point 221 is located on the sliding seat 230, and the baffle 220 is integrally formed with the sliding seat 230, or the baffle 220 is not included. The first compression spring 320 ensures that the movable heating unit 200 always tends to move toward the fixed heating unit 100, thereby facilitating the clamping of the bread slice. In another embodiment, a first tension spring (not shown) has two ends connected to the inner side of the movable heating unit 200 and the fixed heating unit 100, respectively, and is in a tensioned state, similarly ensuring that the movable heating unit 200 always tends to move toward the fixed heating unit 100. The outer side of the movable heating unit 200 refers to the side facing away from the fixed heating unit 100 , and the inner side of the movable heating unit 200 refers to the side facing the fixed heating unit 100 .

[0035] The cam 340 is a vertical cam 341 that is fixed to the bottom of the cam 340 so that the cam 341 is in the vertical direction and the cam 341 is in the horizontal direction. Figure 5 (shown) is the maximum horizontal displacement range of the sliding seat 230. In one embodiment, the horizontal adjustment assembly 300 includes two or more connecting members 340, and the sliding seat 230 has a corresponding number of through-holes 231. In other embodiments, those skilled in the art will readily appreciate other connection methods with a limiting effect to prevent the sliding seat 230 from separating from the horizontal adjustment assembly 300, which will not be described in detail here.

[0036] In some embodiments, the horizontal adjustment assembly 300 can also be other mechanisms capable of achieving relative displacement, such as mechanisms achieving relative displacement through gear rack, cylinder drive, motor drive, etc. Those skilled in the art can think of similar embodiments, which will not be described here.

[0037] In some embodiments, the horizontal adjustment assembly 300 has two states of locking and unlocking. In the locking state, the movable heating unit 200 or the heating sheet 210 can be kept at a specified position. After unlocking, the movable heating unit 200 or the heating sheet 210 returns to a state of free horizontal movement. The locking state can be maintained by friction between two relatively sliding components. In one embodiment, the sliding seat 230 has a convex edge 232, and the horizontal adjustment assembly 300 includes a second side plate 330 having a sliding groove 331 or guide rail allowing the convex edge 232 to slide therein. In another embodiment, the locking state can also be maintained by friction between the aforementioned connecting member 340 and the sliding seat 230. In other embodiments, the locking state can also be achieved by limiting components with more stable locking state, such as components with limiting protrusions and recesses.

[0038] In another embodiment, the movable heating unit 200 is fixedly connected with the horizontal adjustment assembly 300, and the horizontal adjustment assembly 300 is slidingly connected with the frame 500 in the horizontal direction. At this time, the displacement of the horizontal adjustment assembly 300 in the horizontal direction is equivalent to the displacement of the movable heating unit 200 in the horizontal direction. In one embodiment, the horizontal adjustment assembly 300 includes a fourth connecting position 312 on the first side plate 310, the frame 500 includes a fifth connecting position 522 on the frame 500 corresponding to the fourth connecting position 312, and the two ends of the second return spring 350 are connected with the fourth connecting position 312 and the fifth connecting position 522, respectively, and are deformed in the horizontal direction between the fourth connecting position 312 and the fifth connecting position 522. The second return spring 350 is used to reduce the tendency of the movable heating unit 200 during movement, to protect the related components from being damaged by sudden impact, and to keep the movable heating unit 200 moving towards the fixed heating unit 100, so as to facilitate proper clamping of the bread slice.

[0039] The utility model also includes a driving assembly 400 mounted on the frame 500. In one embodiment, the driving assembly 400 is connected with the horizontal adjustment assembly 300.

[0040] In one embodiment, the frame 500 includes a base 530, such as Figure 2As shown, the base 530 has a guide groove 531 to guide the movable heating unit 200 or the horizontal adjustment assembly 300 to slide back and forth. The frame 500 also includes a first mounting portion 510 and a second mounting portion 520 located on the base 530. The two ends of the fixed heating unit 100 are respectively mounted and connected to the first mounting portion 510 and the second mounting portion 520. In one embodiment, the fixed heating unit 100 includes a fixed heating plate 110 and a fixed heat insulation plate 140 covering the outer side of the fixed heating plate 110. The first mounting portion 510 and the second mounting portion 520 are symmetrically arranged. Taking the first mounting portion 510 as an example, the first mounting portion 510 has a first mounting groove 511 and a second mounting groove 512. The first mounting groove 511 accommodates the side edge of the end of the fixed heating plate 110 to install the fixed heating plate 110, and the second mounting groove 512 accommodates the side edge of the end of the fixed heat insulation plate 140 to install the fixed heat insulation plate 140. The second mounting portion 520 has a corresponding structure and is not further described.

[0041] The second mounting portion 520 is mounted with the driving assembly 400. Figure 5 As shown, the driving assembly 400 includes a movable part 410 and a driving part 420. The driving part 420 can be a button, handle or other component that is convenient for manual driving, or it can be a driving component including a motor. In one embodiment, the driving part 420 has a motor 421 and a gear 422 connected to the output shaft of the motor 421. The movable part 410 has a rack 413 engaged with the gear 422. When the motor 421 drives the gear 422 to rotate, the movable part 410 moves up and down. The movable portion 410 has a force-applying inclined surface 411 at its lower portion, and the second side plate 330 has a force-receiving inclined surface 332. When the movable portion 410 moves downward, the force-applying inclined surface 411 presses downward against the force-receiving inclined surface 332, causing the second side plate 330 to move horizontally toward the fixed heating unit 100, thereby converting the vertical movement of the movable portion 410 into horizontal movement of the horizontal adjustment assembly 300. Conversely, when the movable portion 410 moves upward, the second side plate 330 moves horizontally away from the fixed heating unit 100 under the restoring force of the second return spring 350. When the movable heating unit 200, driven by the horizontal adjustment assembly 300, moves to the user's desired position (suitable for the width of the bread slice), the motor 421 stops operating, and the movable portion 410 and the horizontal adjustment assembly 300 (the movable heating unit 200) remain in their current position.

[0042] In one embodiment, the lower portion of the movable portion 410 has a pair of symmetrical force-applying inclined surfaces 411, such as Figure 1As shown, the two force receiving inclined surfaces 332 can be forced simultaneously to drive the movable heating unit 200 located on both sides of the fixed heating unit 100. In another embodiment, the number of the movable parts 410 is two, and each of the movable parts 410 is forced to drive the corresponding force receiving inclined surface 332. In one embodiment, two adjacent force receiving inclined surfaces 332 have the same inclination angle, and in another embodiment, two adjacent force receiving inclined surfaces 332 have symmetrical inclination angles.

[0043] In another embodiment, the driving assembly 400 directly drives the baffle 220 to move the movable heating unit 200, and the movable heating unit 200 moves horizontally relative to the horizontal adjustment assembly 300 and / or the frame 500.

[0044] In a simple embodiment, the horizontal adjustment assembly 300 is not provided, and the driving assembly 400 directly drives the movable heating unit 200. For example, the force receiving inclined surface is located on the baffle 220 or the sliding seat 230, and the driving assembly 400 directly drives the force receiving inclined surface on the baffle 220 or the sliding seat 230. Figure 2 As shown, the base 530 has a guide groove 531 to guide the bottom of the sliding seat 230 to slide back and forth. In one embodiment, the movable heating unit 200 is connected to the frame 500 through a reset mechanism.
