Detailed implementation manners
[0026] The present utility model will be further described below with reference to the accompanying drawings.
[0027] The fully heat-dissipating damping-opening and -closing baking machine of the present utility model, as Figures 1 to 5As shown, it includes a lower plate assembly 1 and an upper cover assembly 2. A lower heating tube 13 is provided inside the lower plate assembly 1, and an upper heating tube 23 is provided inside the upper cover assembly 2. The upper cover assembly 2 is correspondingly covered on the lower plate assembly 1. An upper cooling fan 25 is provided inside the upper cover assembly 2, and the upper cooling fan 25 is arranged above the upper heating tube 23. An upper panel 24 is provided inside the upper cover assembly 2 (it should be noted that Figure 2 , Figure 8 and Figure 9 do not draw the upper panel 24), and the upper panel 24 is arranged below the upper heating tube 23. Thus, when the upper cooling fan 25 works, it can drive the air flow inside the upper cover assembly 2, which is beneficial to the heat dissipation of the upper cover assembly 2 to the outside air. As Figures 1 to 5 shown, a lower panel 14 is provided inside the lower plate assembly 1, and the lower panel 14 is arranged above the lower heating tube 13. A lower cooling fan 15 is provided inside the lower plate assembly 1, and the lower cooling fan 15 is arranged below the lower heating tube 13. As Figure 3 shown, the upper cover assembly 2 has a closed position relative to the lower plate assembly 1. In the closed position, a gap 100 for accommodating food is formed between the lower panel 14 and the upper panel 24.
[0028] During the process of using the toaster, as Figure 2 shown, for example, place the pizza on the lower panel 14, and then cover the upper cover assembly 2 on the lower plate assembly 1. At this time, the upper panel 24 is directly opposite the lower panel 14, and the pizza is located in the gap 100. Then, make the lower heating tube 13 and the upper heating tube 23 work. The heat generated by the lower heating tube 13 mainly bakes the bottom of the pizza, and the heat generated by the upper heating tube 23 mainly bakes the top of the pizza. Due to the blocking effect of the lower panel 14, the pizza is prevented from contacting the lower heating tube 13. Due to the blocking effect of the upper panel 24, the pizza is prevented from contacting the upper heating tube 23. When the baking is completed, open the upper cover assembly 2, and the cooked pizza can be taken away from the lower panel 14. During the working process of the toaster of the present invention, the lower cooling fan 15 rotates to generate an air flow, making the air flow at the position of the lower plate assembly 1, which is beneficial to dissipating the excess heat transferred downward by the lower heating tube 13 to the outside air, thereby preventing the outer wall of the lower plate assembly 1 from accumulating high temperature and preventing the user from feeling hot when touching the outer wall of the lower plate assembly 1; during the working process of the toaster of the present invention, the upper cooling fan 25 rotates to generate an air flow, making the air flow at the position of the upper cover assembly 2, which is beneficial to dissipating the excess heat transferred upward by the upper heating tube 23 to the outside air, thereby preventing the outer wall of the upper cover assembly 2 from accumulating high temperature and preventing the user from feeling hot when touching the outer wall of the upper cover assembly 2; thus, the toaster of the present invention has an overall heat dissipation effect up and down, avoiding the situation of scalding the user's hands and also preventing the components inside the toaster from being damaged due to excessive temperature. Therefore, the toaster of the present invention has high use safety.
[0029] Furthermore, asFigure 1 , Figure 2 and Figure 7 As shown in Figure 1 , Figure 2 and Figure 7 , the lower plate assembly 1 is hinged to the upper cover assembly 2 through a rotary damper 3. The rotary damper 3 is a prior art. The rotary damper 3 includes a cylinder shell and a rotating shaft portion 301. When the rotating shaft portion 301 rotates relative to the cylinder shell, a relatively obvious resistance moment is generated between the rotating shaft portion 301 and the cylinder shell. That is to say, it is necessary to overcome the above resistance moment to make the rotating shaft portion 301 and the cylinder shell rotate relative to each other. For example, reference can be made to the "damping hinge" with the Chinese utility model patent publication number CN2253762Y and the "rotary damper and manufacturing method thereof" with the Chinese invention patent publication number CN100385139C. For example, the rotating shaft portion 301 can be circumferentially relatively positioned with the upper cover assembly 2, and the above cylinder shell can be circumferentially relatively positioned with the lower plate assembly 1. For example, when the upper cover assembly 2 is opened by hand, it is necessary to overcome the resistance of the rotary damper 3 to avoid impact when the upper cover assembly 2 is opened to the limit position. When the upper cover assembly 2 is closed by hand, it is also necessary to first overcome the obstructive effect of the rotary damper 3. When the upper cover assembly 2 is closed to a position close to the limit position, the upper cover assembly 2 can be self-closed by the gravity of the upper cover assembly 2 overcoming the obstructive effect of the rotary damper 3, so as to avoid violent collision between the upper cover assembly 2 and the lower plate assembly 1 when the upper cover assembly 2 is closed, avoid pinching the human hand by the upper cover assembly 2, and also avoid obvious collision noise. It is also possible to set the damping of the rotary damper 3 to be relatively large, so that the whole process of opening and closing the upper cover assembly 2 requires the human hand to overcome the obstructive effect of the rotary damper 3, so that the upper cover assembly 2 can stay at any position (within the swing stroke range of the upper cover assembly 2). Of course, the rotary damper 3 can be a one-way rotary damper. For example, reference can be made to the "a rotary damper" with the Chinese utility model patent publication number CN212985884U, so that the upper cover assembly 2 is obstructed by the rotary damper 3 when it is closed, but the upper cover assembly 2 is generally not obstructed by the rotary damper 3 when it swings in the opening direction, thus realizing both convenient opening of the cover and avoiding pinching the hand when closing the cover. By setting the rotary damper 3, it is beneficial to improve the use safety of the baking machine of the present invention.
[0030] Furthermore, as Figure 8 shown, the lower plate assembly 1 includes a hinge seat 16. As Figure 9 shown, one end of the hinge seat 16 forms a hinge shaft head 161. The hinge shaft head 161 and the hinge seat 16 body can be integrally provided. As Figure 8 shown, the upper cover assembly 2 includes a groove shell 26. One end of the groove shell 26 forms a hinge hole 201. As Figure 9 shown, the other end of the groove shell 26 corresponding to it forms a connection hole 202. As Figure 7 and Figure 8As shown, the rotary damper 3 is installed in the hinge seat 16. Specifically, as Figure 10 shown, first, the rotary damper 3 is inserted into the hinge seat 16, so that the rotating shaft portion 301 of the rotary damper 3 extends out of the hinge seat 16. Then, the damper fixing seat 4 is installed inside the hinge seat 16 through corresponding screws. The damper fixing seat 4 covers the lower side of the cylinder shell of the rotary damper 3. As Figure 12 shown, a groove 41 is formed on the upper side of the damper fixing seat 4. The groove 41 is adapted to the cylinder shell of the rotary damper 3. A slot 401 is formed on the upper side of the damper fixing seat 4. As Figure 11 shown, a cylinder end plate 302 is formed on the cylinder shell of the rotary damper 3. The cylinder end plate 302 is adapted to be inserted into the slot 401, thereby preventing the cylinder shell of the rotary damper 3 from circumferentially shifting relative to the hinge seat 16. As Figure 7 Combined with Figure 9 shown, the upper end of the hinge seat 16 is provided in the groove shell 26. The rotary damper 3 includes a rotating shaft portion 301. The rotating shaft portion 301 is adapted to be provided in the connection hole 202. The rotating shaft portion 301 and the connection hole 202 are circumferentially relatively positioned. For example, the rotating shaft portion 301 is a flat shaft structure. As Figure 9 shown, the connection hole 202 can be a rectangular concave hole, so that the rotating shaft portion 301 and the connection hole 202 are circumferentially relatively positioned. The hinge shaft head 161 is provided in the hinge hole 201. During this period, the hinge hole 201 can be a hole with a notch. After inserting the rotating shaft portion 301 into the connection hole 202, the hinge shaft head 161 is then swung into the hinge hole 201. The groove shell 26 is installed on the lower side of one end of the cover shell 21 through corresponding screws. The cover shell 21 closes the notch of the above-mentioned hinge hole 201. As Figure 2 And Figure 8 shown, the hinge seat 16 is installed on the upper side of one end of the bottom shell 11 through corresponding screws. By providing that one end of the groove shell 26 forms a hinge hole 201 and the other corresponding end of the groove shell 26 forms a connection hole 202, it is beneficial to balance the supporting force of the upper cover assembly 2. By providing that the rotary damper 3 is installed in the hinge seat 16 and the upper end of the hinge seat 16 is provided in the groove shell 26, it is possible to prevent food debris or juice from sticking to the rotary damper 3, which is beneficial to the durability of the rotary damper 3.
[0031] Furthermore, as Figures 2 to 5 shown, the lower disc assembly 1 includes a bottom shell 11 and a lower reflector 12. The lower reflector 12 is provided in the bottom shell 11. The lower heating tube 13 is provided in the lower reflector 12. The lower cooling fan 15 is provided below the lower reflector 12. As Figure 6 shown, an air inlet 111 is formed at the central part of the bottom shell 11. The bottom shell 11 is formed with shell cooling holes 1102. The shell cooling holes 1102 are distributed on the outside of the air inlet 111. As Figure 3As shown in the figure, the lower cooling fan 15 is disposed on the corresponding upper side of the air inlet 111. When the lower cooling fan 15 operates, the lower cooling fan 15 attracts the outside air to enter the bottom case 11 from the bottom to the top through the air inlet 111. Since the lower cooling fan 15 is disposed below the lower reflector 12, the air flow then diverges outward along the outer bottom surface of the lower reflector 12, as Figure 3 shown. After that, the air flow is discharged out of the bottom case 11 through the case heat dissipation holes 1102, and the air flow effectively discharges the heat inside the lower disk assembly 1 (and outside the lower reflector 12) to the external environment, preventing the user from feeling the heat when touching the outer wall of the lower disk assembly 1. Moreover, the above air flow flows orderly from the center to the outside, which is beneficial to improving the heat dissipation efficiency.
[0032] Furthermore, as Figure 6 shown, the bottom case 11 is formed with a concave disk 110, and the air inlet 111 is formed at the bottom of the concave disk 110, as Figure 3 shown. The lower cooling fan 15 is disposed in the concave disk 110, as Figure 6 shown. The lower side of the bottom case 11 is formed with feet 112, and the feet 112 are arranged outside the concave disk 110. Then the lower ends of the feet 112 are used to contact the kitchen countertop, and the feet 112 support the bottom case 11 to leave a space between the bottom case 11 and the kitchen countertop. The concave disk 110 makes full use of the above space, avoiding the need to increase the height of the lower disk assembly 1.
[0033] Furthermore, as Figure 6 shown, the side surface of the concave disk 110 is formed with circumferentially distributed concave disk heat dissipation holes 1101, which is beneficial to increasing the heat dissipation range of the bottom case 11.
[0034] Furthermore, as Figures 3 to 5 shown, the upper cover assembly 2 includes a cover shell 21, an upper reflector 22 and a heat insulation disk 220. The upper heating tube 23 is disposed in the upper reflector 22, the upper reflector 22 is disposed in the heat insulation disk 220, and there is a heat insulation space between the outer wall of the upper reflector 22 and the inner wall of the heat insulation disk 220. The heat insulation disk 220 is disposed in the cover shell 21, and the upper cooling fan 25 is disposed on the upper side of the heat insulation disk 220. The upper cooling fan 25 is disposed on the lower side of the top of the cover shell 21; when the upper heating tube 23 works, it will also heat the upper reflector 22. Due to the principle that hot air rises, the air heated by the outer wall of the upper reflector 22 flows upward. Therefore, the temperature of the outer wall of the upper cover assembly 2 (i.e., the outer wall of the cover shell 21) is more likely to rise. By setting the heat insulation disk 220, it effectively prevents the heat generated by the upper heating tube 23 from dissipating outward, and is also beneficial to relatively reducing the temperature of the cover shell 21, as Figure 1As shown, a cover vent 2101 is formed on the cover housing 21. When viewed from above, the cover vent 2101 is formed around the outside of the upper cooling fan 25. Due to the principle that hot air rises and due to the relatively large area of the cover vent 2101, the air flow blown downward by the upper cooling fan 25 onto the outer wall of the heat insulation plate 220 can be discharged through the cover vent 2101.
[0035] The lower heating tube 13 and the upper heating tube 23 can be infrared heating tubes of the prior art. Thus, both the lower panel 14 and the upper panel 24 can be quartz glass panels. The lower reflecting disc 12 reflects the infrared rays emitted downward by the lower heating tube 13 upward, and the upper reflecting disc 22 reflects the infrared rays emitted upward by the upper heating tube 23 downward, thereby facilitating energy efficiency improvement. As Figure 3 shown, a first positioning step is formed inside the upper reflecting disc 22, and the upper panel 24 abuts against the lower side of the above-mentioned first positioning step. A second positioning step is formed inside the lower reflecting disc 12, and the lower panel 14 abuts against the upper side of the above-mentioned second positioning step.
[0036] In addition to being able to bake pizza, the baking machine of the present utility model can also bake foods with similar shapes, such as meat patties or toast.
[0037] During operation, the outer wall temperature of the baking machine of the present utility model is relatively low, which helps the baking machine product of the present utility model to more easily meet the safety standards for household electrical appliances in Europe.
