Description

Technical Field

[0001] The present invention relates to the field of food production equipment, and more specifically, to a waffle maker. Background Art

[0002] A waffle is a baked cake that originated in Belgium and is made using an oven equipped with a special baking pan.

[0003] Existing waffle makers generally include an upper housing and a lower housing. An upper baking pan and a lower baking pan are respectively installed on the upper housing and the lower housing. The cavity formed after the upper baking pan and the lower baking pan are closed is the raw material accommodating chamber for the waffles. And heating devices are provided on the back surfaces of the upper baking pan and the lower baking pan. Pour the raw materials into the chamber, close the mold and heat the upper baking pan and the lower baking pan to a certain temperature and keep it for a period of time. After the raw materials receive the heat transferred from the upper baking pan and the lower baking pan, the moisture in the raw materials evaporates and becomes solid, that is, the waffles are formed.

[0004] However, there are some problems when using existing waffle makers: 1. Since the upper and lower parts of the existing waffle maker are hinged by two housings, when heated and baked, at this time, since the baking pans are in a relatively high temperature state, when the upper housing is opened, the upper housing and the lower housing are in a vertical state. At this time, it is very easy to cause the upper housing to fall due to accidental collision or vibration, resulting in adverse situations such as personal injury.

[0005] 2. Since the upper and lower parts of the existing waffle maker are hinged by two housings, in actual use, oil stains are likely to accumulate at the hinge position, and it is extremely troublesome to clean.

[0006] 3. When cleaning the baking pans after use, it is usually scrubbed forward or to the left and right sides. If the baking pans are fixed with screws on the front side or the left and right sides of the baking pans, oil stains and the like are very easy to contaminate the positions of the screws and the like, thus causing difficulties in cleaning.

[0007] Therefore, it needs to be improved. Summary of the Invention

[0008] The purpose of the present invention is to provide a waffle maker to solve the above problems.

[0009] The above technical purpose of the present invention is achieved through the following technical solutions: A waffle maker, including a lower housing and an upper housing with a handle. Lower baking pans and upper baking pans are respectively installed on the opposite surfaces of the lower housing and the upper housing. Electric heating tubes are fixedly installed on the opposite surfaces of the lower baking pans and the upper baking pans. An articulated mechanism for rotatably matching the upper housing and the lower housing is installed between the lower baking pan and the upper baking pan. A limiting mechanism for locking the articulated mechanism to keep the lower housing and the upper housing in a relatively open state is arranged in the upper housing.

[0010] By setting a limiting mechanism, after the waffle is heated and baked, when the upper shell is opened at this time, under the action of the limiting mechanism, the upper shell and the lower shell can be kept in a vertical state, avoiding the situation that the upper shell accidentally falls over and causes harm to the user, thus improving safety.

[0011] Preferably, one side of the lower baking tray is fixedly connected with a first arc-shaped plate and a first mounting seat. A first shaft hole and a first side U-shaped groove communicating with the first shaft hole and opening upward are arranged on the first mounting seat. One end of the first arc-shaped plate far away from the first mounting seat is integrally formed with a first circular block, and a first shaft column is integrally formed at the center position of the first circular block. One side of the upper baking tray is fixedly connected with a second arc-shaped plate and a second mounting seat. A second shaft hole and a second side U-shaped groove communicating with the second shaft hole and opening downward are arranged on the second mounting seat. One end of the second arc-shaped plate far away from the second mounting seat is integrally formed with a second circular block, and a second shaft column is integrally formed at the center position of the second circular block. Thus, a hinge mechanism that enables the upper shell and the lower shell to rotate relative to each other is formed.

[0012] By setting the above structure, when the upper baking tray and the lower baking tray are assembled in cooperation, first place them in corresponding positions, that is, align the second shaft column with the first side U-shaped groove and align the first shaft column with the second side U-shaped groove. Then apply a little downward force to make the second mounting seat move downward and squeeze through the gap between the first shaft column and the lower shell until the second shaft column is aligned with the first shaft hole and the first shaft column is aligned with the second shaft hole. At this time, simultaneously insert the second shaft column and the first shaft column into the first shaft hole and the second shaft hole respectively to achieve smooth rotational cooperation, that is, the hinge position between the upper baking tray and the lower baking tray is on the same straight line, thereby realizing stable rotation between the upper baking tray and the lower baking tray. The entire assembly process is simple and efficient, and no additional tools are required.

[0013] Preferably, the first arc-shaped plate is located between the second arc-shaped plate and the second mounting seat, the second arc-shaped plate is located between the first arc-shaped plate and the first mounting seat. The first arc-shaped plate is arched upward, the second arc-shaped plate is sunken downward, the centers of the first arc-shaped plate and the second arc-shaped plate are on the same straight line, and when the lower shell and the upper shell are in a vertical state, the first arc-shaped plate and the second arc-shaped plate are aligned with each other.

[0014] By setting the first arc plate and the second arc plate, during the opening process of the upper shell, the second arc plate will move synchronously with the upper baking tray. Until when the lower shell and the upper shell are in a vertical state, the first arc plate and the second arc plate are aligned with each other, that is, the projections of the first arc plate and the second arc plate on the side vertical plane completely overlap. Thus, the hinged position between the upper baking tray and the lower baking tray is separated from their actual baking positions, that is, oil stains can be blocked by the first arc plate and the second arc plate, preventing oil stains from entering the hinged position between the upper baking tray and the lower baking tray, thereby reducing the cleaning difficulty.

[0015] Preferably, the limiting mechanism includes: a limiting hole provided on the side surface of the first shaft column; a limiting pin shaft slidably connected to the second mounting seat, and a first spring for pushing the limiting pin shaft into the limiting hole is installed between the limiting pin shaft and the second mounting seat; a push block slidably mounted on the handle, and a steel wire rope for driving the limiting pin shaft to disengage from the limiting hole is fixedly connected between the push block and the limiting pin shaft.

[0016] During the opening process of the upper shell, the limiting pin shaft slides along the side surface of the first shaft column under the action of the first spring until the limiting pin shaft is aligned with the limiting hole. At this time, the limiting pin shaft is driven by the first spring to be inserted into the limiting hole to achieve the locking effect, that is, the upper shell is in the open state and is not prone to falling over under the action of external force, thereby greatly improving the safety of use. When the upper shell needs to be closed, only need to slide the push block, and use the arrangement of the steel wire rope to pull the limiting pin shaft to move outwards to disengage from the limiting hole. At this time, the upper shell can be rotated smoothly, which is simple and convenient to use and has high safety.

[0017] Preferably, a plurality of positioning blocks are fixedly connected inside the upper shell, and positioning holes for the steel wire rope to pass through are provided on the positioning blocks.

[0018] By setting the positioning blocks with positioning holes, the arrangement of the steel wire rope can be made more integral, and the moving path of the steel wire rope can be effectively controlled, improving the operation fluency.

[0019] Preferably, one side of the lower shell is bent outwards to form an arc-shaped box body for placing the hinge mechanism. A support plate located below the first arc plate is fixedly connected to the middle of the inner wall of the arc-shaped box body. The support plate and the first arc plate are in clearance fit. A cover shell for sleeving outside the arc-shaped box body is integrally formed on one side of the upper shell.

[0020] By setting the mutually matching arc-shaped box body and the cover shell, the components hinged between the upper baking tray and the lower baking tray can be placed in the arc-shaped box body to achieve the covering and protecting effects on the hinged components, and the rotation range of the upper shell relative to the lower shell can be limited to a certain extent to ensure the use effect.

[0021] Preferably, at least two first mounting blocks are fixedly connected to the side of the back surface of the lower baking tray away from the first arc-shaped plate. Each first mounting block is provided with a jack. At least two upright columns are formed inside the lower housing. A positioning post for inserting into the jack is fixedly connected to each upright column. At least two first through holes are provided on the side of the lower baking tray close to the first arc-shaped plate. A first screw passing through the first through hole is threadedly connected to the lower housing to realize the relative fixation of the lower baking tray and the lower housing. A plurality of first convex strips facing the lower housing and distributed in a circumferential array are arranged around the first through hole at the edge of the lower baking tray.

[0022] When assembling the lower baking tray, first align the jacks on the lower baking tray with the positioning posts on the upright columns, press down the lower baking tray, drive the lower baking tray to move downward and insert the positioning posts into the jacks to achieve the overall positioning effect of the lower baking tray. After pressing down, at this time, the first through holes are aligned with the screw holes on the lower housing. Use the first screws to pass through the first through holes and threadedly tighten them with the screw holes on the lower housing to realize the relative fixation of the lower baking tray and the lower housing, so that the lower baking tray can be stably assembled on the lower housing, and the operation is simple and convenient. Only two first screws need to be tightened near the hinge position. Therefore, the front side and the left and right sides of the lower baking tray can all maintain integrity, which is convenient for oil stain scrubbing. At the same time, since the first convex strips are pressed during the screwing process of the first screws, the stability of the first screws can be improved, making them not easy to loosen, thereby further strengthening the stability of the lower baking tray.

[0023] Preferably, at least two second mounting blocks are fixedly connected to the side of the back surface of the upper baking tray away from the second arc-shaped plate. A limiting piece is fixedly connected to each second mounting block. A limiting seat with a slot is fixedly connected inside the upper housing. At least two second through holes are provided on the side of the upper baking tray close to the second arc-shaped plate. A second screw passing through the second through hole is threadedly connected to the upper housing to realize the relative fixation of the upper baking tray and the upper housing. A plurality of second convex strips facing the upper housing and distributed in a circumferential array are arranged around the second through hole at the edge of the upper baking tray.

[0024] When assembling the upper baking tray, first insert the limiting pieces into the slots of the limiting seat, that is, achieve a certain positioning effect of the upper baking tray on the upper housing. At this time, the second through holes are aligned with the screw holes on the upper housing. Use the second screws to pass through the second through holes and threadedly tighten them with the screw holes on the upper housing to realize the relative fixation of the upper baking tray and the upper housing, so that the upper baking tray can be stably assembled on the upper housing, and the operation is simple and convenient. Only two second screws need to be tightened near the hinge position. Therefore, the front side and the left and right sides of the upper baking tray can all maintain integrity, which is convenient for oil stain scrubbing. At the same time, since the second convex strips are pressed during the screwing process of the second screws, the stability of the second screws can be improved, making them not easy to loosen, thereby further strengthening the stability of the upper baking tray.

[0025] Preferably, a stabilizing mechanism for pushing the limiting piece to abut against the inner wall of the slot is installed inside the upper housing. The stabilizing mechanism includes a fixing frame fixedly connected to the inside of the upper housing, a supporting frame slidably connected to the fixing frame, and an abutting plane provided on the back of the upper baking tray. A limiting block is fixedly connected to the supporting frame, and sliding columns slidably engaged with the supporting frame are fixedly connected to the four corners of the edge of the supporting frame. A limiting baffle is fixedly connected to the side of the sliding column away from the supporting frame, and a second spring is fixedly installed between the supporting frame and the fixing frame.

[0026] Since the limiting piece and the slot are in clearance fit, by setting the stabilizing mechanism, when the upper baking tray is assembled, because the abutting plane of the upper baking tray will contact the limiting block, and under the action of the second spring, the limiting block pushes the upper baking tray to move outwards until the limiting piece abuts against the inner wall of one of the slots, avoiding the situation that the limiting piece offsets in the slot during use and improving the use effect.

[0027] Preferably, a guiding arc surface is provided on the edge of the side of the limiting block away from the supporting frame.

[0028] By setting the guiding arc surface, after the limiting piece of the upper baking tray is inserted into the slot of the limiting seat, the abutting plane of the upper baking tray can contact and compress the second spring along the guiding arc surface until it contacts and abuts against the surface of the limiting block under the action of the second spring, making the assembly safer and more efficient.

[0029] In summary, the present invention has the following beneficial effects: 1. By setting the limiting mechanism in the present invention, during the opening process of the upper housing, the limiting pin slides along the side surface of the first shaft column under the action of the first spring until the limiting pin is aligned with the limiting hole. At this time, the limiting pin is driven by the first spring to be inserted into the limiting hole to achieve the locking effect, that is, the upper housing is in the open state and is not prone to falling over and other situations under external force, thereby greatly improving the safety of use.

[0030] 2. By setting the first arc-shaped plate and the second arc-shaped plate in the present invention, during the opening process of the upper housing, the second arc-shaped plate will move synchronously with the upper baking tray until when the lower housing and the upper housing are in a vertical state, the first arc-shaped plate and the second arc-shaped plate are aligned with each other, that is, the projections of the first arc-shaped plate and the second arc-shaped plate on the side vertical plane completely coincide. Thus, the hinged position between the upper baking tray and the lower baking tray is separated from their actual baking positions, that is, the oil stain can be blocked by the first arc-shaped plate and the second arc-shaped plate, preventing the oil stain from entering the hinged position between the upper baking tray and the lower baking tray, thereby reducing the cleaning difficulty.

[0031] 3. When assembling the upper baking tray and the lower baking tray of the present invention, the ends of the upper baking tray and the lower baking tray far from their hinged positions are positioned by plugging, and the ends close to their hinged positions are fixed with two screws, so that stable assembly is achieved between the upper baking tray and the upper housing, and between the lower baking tray and the lower housing. Moreover, the operation is simple and convenient, only two first screws need to be tightened. Therefore, the front side and the left and right sides of the upper baking tray and the lower baking tray can all maintain integrity, which is convenient for oil stain scrubbing treatment.

Detailed implementation manner

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1-3 shown, a waffle maker includes a lower housing 1 and an upper housing 2. A handle 21 is provided on the upper housing 2 to facilitate its opening and closing. A lower baking tray 3 and an upper baking tray 4 are respectively installed on the opposite surfaces of the lower housing 1 and the upper housing 2. Electric heating tubes 5 are fixedly installed on the opposite surfaces of the lower baking tray 3 and the upper baking tray 4. A hinge mechanism for rotatably matching the upper housing 2 and the lower housing 1 is installed between the lower baking tray 3 and the upper baking tray 4. A limiting mechanism for locking the hinge mechanism to keep the lower housing 1 and the upper housing 2 in a relatively open state is provided in the upper housing 2. Thus, after heating and baking the waffles, when the upper housing 2 is opened, under the action of the limiting mechanism, the upper housing 2 and the lower housing 1 can be kept in a vertical state, avoiding the situation that the upper housing 2 accidentally falls over and causes harm to the user, and improving safety.

[0036] Further, as Figures 6-9As shown in the figure, one side of the lower baking tray 3 is fixedly connected with a first arc-shaped plate 31 and a first mounting seat 32. The first mounting seat 32 is provided with a first shaft hole and a first side U-shaped groove that is communicated with the first shaft hole and opens upward. One end of the first arc-shaped plate 31 far away from the first mounting seat 32 is integrally formed with a first circular block 311, and a first shaft column 312 is integrally formed at the central position of the first circular block 311. One side of the upper baking tray 4 is fixedly connected with a second arc-shaped plate 41 and a second mounting seat 42. The second mounting seat 42 is provided with a second shaft hole and a second side U-shaped groove that is communicated with the second shaft hole and opens downward. One end of the second arc-shaped plate 41 far away from the second mounting seat 42 is integrally formed with a second circular block 411, and a second shaft column 412 is integrally formed at the central position of the second circular block 411. In this way, a hinge mechanism that enables the upper shell 2 and the lower shell 1 to rotate relative to each other is formed. That is, when the upper baking tray 4 and the lower baking tray 3 are assembled in cooperation, first place the two in corresponding positions, so that the second shaft column 412 is aligned with the first side U-shaped groove and the first shaft column 312 is aligned with the second side U-shaped groove. Then apply a little downward force, so that the second mounting seat 42 moves downward and squeezes through the gap between the first shaft column 312 and the lower shell 1 until the second shaft column 412 is aligned with the first shaft hole and the first shaft column 312 is aligned with the second shaft hole. At this time, synchronously insert the second shaft column 412 and the first shaft column 312 into the first shaft hole and the second shaft hole respectively to achieve smooth rotational cooperation. At this time, the hinge position between the upper baking tray 4 and the lower baking tray 3 is on the same straight line, realizing stable rotation between the upper baking tray 4 and the lower baking tray 3. The entire assembly process is simple and efficient, and no additional tools are required.

[0037] Furthermore, as Figures 6-9 shown, the first arc-shaped plate 31 is located between the second arc-shaped plate 41 and the second mounting seat 42, the second arc-shaped plate 41 is located between the first arc-shaped plate 31 and the first mounting seat 32. The first arc-shaped plate 31 is in an upward-arching state, the second arc-shaped plate 41 is in a downward-sunken state. The centers of the first arc-shaped plate 31 and the second arc-shaped plate 41 are on the same straight line, and when the lower shell 1 and the upper shell 2 are in a vertical state, the first arc-shaped plate 31 and the second arc-shaped plate 41 are aligned with each other. Therefore, during the opening process of the upper shell 2, the second arc-shaped plate 41 will move synchronously with the upper baking tray 4 until when the lower shell 1 and the upper shell 2 are in a vertical state, the first arc-shaped plate 31 and the second arc-shaped plate 41 are aligned with each other, that is, the projections of the first arc-shaped plate 31 and the second arc-shaped plate 41 on the vertical plane of the side are completely coincident. Thus, the hinge position between the upper baking tray 4 and the lower baking tray 3 is separated from their actual baking positions, that is, oil stains can be blocked by the first arc-shaped plate 31 and the second arc-shaped plate 41, preventing oil stains from entering the hinge position between the upper baking tray 4 and the lower baking tray 3, thereby reducing the cleaning difficulty.

[0038] It is worth mentioning that, as Figure 1 and Figure 3As shown, one end of the upper housing 2 away from its hinged position is fixedly connected with a covering baffle 22 for blocking the gap between the upper baking tray 4 and the lower baking tray 3 when closing, so as to avoid splashing of hot oil and the like during baking and hurting the user, thus improving safety.

[0039] Furthermore, as Figure 1 , Figure 3 , Figure 9 and Figure 10 shown, the limiting mechanism includes a limiting hole 3121 arranged on the side surface of the first shaft column 312, a limiting pin shaft 421 slidably connected to the second mounting seat 42, and a push block 211 slidably mounted on the handle 21. A first spring 422 for pushing the limiting pin shaft 421 to be inserted into the limiting hole 3121 is installed between the limiting pin shaft 421 and the second mounting seat 42. A steel wire rope 212 for driving the limiting pin shaft 421 to disengage from the limiting hole 3121 is fixedly connected between the push block 211 and the limiting pin shaft 421. Therefore, during the opening process of the upper housing 2, the limiting pin shaft 421 slides along the side surface of the first shaft column 312 under the action of the first spring 422 until the limiting pin shaft 421 is aligned with the limiting hole 3121. At this time, the limiting pin shaft 421 is driven by the first spring 422 to be inserted into the limiting hole 3121 to achieve the locking effect, that is, the upper housing 2 is in the open state and is not likely to fall over and other situations under the action of an external force, thereby greatly improving the safety of use. When the upper housing 2 needs to be closed, only need to slide the push block 211, and use the arrangement of the steel wire rope 212 to pull the limiting pin shaft 421 to move outwards to disengage from the limiting hole 3121. At this time, the upper housing 2 can be rotated smoothly, which is simple and convenient to use and has high safety.

[0040] It is worth mentioning that, as Figure 8 shown, the limiting hole 3121 can be set to two or three; First, the limiting hole 3121 is set to two. At this time, the connecting lines between the centers of the two limiting holes 3121 and the center line of the first shaft column 312 form a 90-degree angle, that is, one of the limiting holes 3121 locks when the upper housing 2 and the lower housing 1 are in a vertical state, and the other limiting hole 3121 locks when the upper housing 2 and the lower housing 1 are in a horizontal state, avoiding the first spring 422 being continuously compressed when the waffle maker is not in use and affecting its service life, and enhancing its practicability; In the second case, the limiting holes 3121 are set to be three. At this time, the connecting line between the center of the middle limiting hole 3121 and the center line of the first shaft column 312 forms a 45-degree angle with the connecting lines between the centers of the two side limiting holes 3121 and the center line of the first shaft column 312. That is, one of the limiting holes 3121 locks when the upper shell 2 and the lower shell 1 are in a vertical state, the middle limiting hole 3121 locks when the upper shell 2 is in a semi-open state. In a relatively large waffle maker, it is not necessary to fully open it to add materials, and the baking is faster. The other limiting hole 3121 locks when the upper shell 2 and the lower shell 1 are in a horizontal state, avoiding the first spring 422 being continuously compressed when the waffle maker is not in use, which affects its service life and enhances its practicability.

[0041] It can be understood that, as Figure 1 shown, a chute is provided at one end of the handle 21 away from the upper shell 2. The push block 211 slides in the chute. Thus, when holding the handle 21, the movement of the push block 211 can be selected to realize the locking and opening situations, and the operation is simple and convenient.

[0042] It is worth mentioning that, as Figure 1 and Figure 6 shown, since the steel wire rope 212 needs to pass through the upper shell 2 and be connected to the push block 211 on the handle 21, a sleeve 26 for the steel wire rope 212 to pass through is fixedly connected between the handle 21 and the upper shell 2 to ensure safety.

[0043] Furthermore, as Figure 1 and Figure 3 shown, a plurality of positioning blocks 23 are fixedly connected inside the upper shell 2. Positioning holes for the steel wire rope 212 to pass through are provided on the positioning blocks 23, which can make the arrangement of the steel wire rope 212 more integral and effectively control the movement path of the steel wire rope 212, improving the operation smoothness.

[0044] Furthermore, as Figure 3 、 Figure 6 and Figure 7 shown, one side of the lower shell 1 bends outward to form an arc-shaped box body 11 for placing the hinge mechanism. A support plate 12 located below the first arc-shaped plate 31 is fixedly connected to the middle of the inner wall of the arc-shaped box body 11. The support plate 12 and the first arc-shaped plate 31 are in clearance fit. A cover shell 24 for sleeving outside the arc-shaped box body 11 is integrally formed on one side of the upper shell 2. It can not only place the components hinged between the upper baking tray 4 and the lower baking tray 3 in the arc-shaped box body 11 to achieve the covering and protecting effects on the hinge components, but also limit the rotation range of the upper shell 2 relative to the lower shell 1 to ensure the use effect.

[0045] Furthermore, as Figure 3 and Figure 7As shown in the figure, on the side of the back of the lower baking tray 3 away from the first arc-shaped plate 31, at least two first mounting blocks 33 are fixedly connected. Each first mounting block 33 is provided with a jack. Inside the lower housing 1, at least two upright columns 13 are formed. On each upright column 13, a positioning post 131 for inserting into the jack is fixedly connected. On the side of the lower baking tray 3 close to the first arc-shaped plate 31, at least two first through holes 34 are provided. A first screw passing through the first through hole 34 is threadedly connected to the lower housing 1 to realize the relative fixation of the lower baking tray 3 and the lower housing 1. Around the first through hole 34 on the edge of the lower baking tray 3, a number of first convex strips facing the lower housing 1 and distributed in a circumferential array are provided. Thus, when assembling the lower baking tray 3, first align the jack of the lower baking tray 3 with the positioning post 131 on the upright column 13, press down the lower baking tray 3, drive the lower baking tray 3 to move downward and make the positioning post 131 insert into the jack to realize the overall positioning effect of the lower baking tray 3. After the pressing is completed, at this time, the first through hole 34 is aligned with the screw hole of the lower housing 1. Use the first screw to pass through the first through hole 34 and threadedly tighten it with the screw hole of the lower housing 1 to realize the relative fixation of the lower baking tray 3 and the lower housing 1, so that the lower baking tray 3 can be stably assembled on the lower housing 1, and the operation is simple and convenient. Only two first screws need to be tightened near the hinge position. Therefore, the front side and the left and right sides of the lower baking tray 3 can both maintain integrity, which is convenient for oil stain scrubbing treatment. At the same time, since the first convex strip is pressed during the screwing down process of the first screw, the stability of the first screw can be improved, making it not easy to loosen, thereby further strengthening the stability of the lower baking tray 3.

[0046] Further, as Figure 3 , Figure 5 , Figure 6 and Figure 7As shown in the figure, at least two second mounting blocks 43 are fixedly connected to the side of the back surface of the upper baking tray 4 away from the second arc-shaped plate 41. A limiting piece 44 is fixedly connected to each second mounting block 43. A limiting seat 25 with a slot is fixedly connected to the inside of the upper housing 2. At least two second through holes 45 are provided on the side of the upper baking tray 4 close to the second arc-shaped plate 41. A second screw passing through the second through hole 45 is threadedly connected to the upper housing 2 to realize the relative fixation of the upper baking tray 4 and the upper housing 2. A number of second convex strips 46 facing the upper housing 2 and distributed in a circumferential array are arranged around the second through hole 45 at the edge of the upper baking tray 4. Thus, when assembling the upper baking tray 4, first insert the limiting piece 44 into the slot of the limiting seat 25, that is, realize a certain positioning effect of the upper baking tray 4 on the upper housing 2. At this time, the second through hole 45 is aligned with the screw hole of the upper housing 2. Use the second screw to pass through the second through hole 45 and threadedly tighten it with the screw hole of the upper housing 2 to realize the relative fixation of the upper baking tray 4 and the upper housing 2, so that the upper baking tray 4 can be stably assembled on the upper housing 2, and the operation is simple and convenient. Only two second screws need to be tightened near the hinge position. Therefore, the front side and the left and right sides of the upper baking tray 4 can all maintain integrity, which is convenient for oil stain scrubbing treatment. At the same time, since the second convex strip 46 is pressed during the screwing process of the second screw, the stability of the second screw can be improved, making it not easy to loosen, thereby further strengthening the stability of the upper baking tray 4.

[0047] Furthermore, as Figure 3 , Figure 4 and Figure 6 shown, a stabilizing mechanism 6 for pushing the limiting piece 44 to abut against the inner wall of the slot is installed inside the upper housing 2. The stabilizing mechanism 6 includes a fixed frame 61 fixedly connected to the inside of the upper housing 2, a support frame 62 slidably connected to the fixed frame 61, and an abutting plane 47 provided on the back surface of the upper baking tray 4. A limiting block 63 is fixedly connected to the support frame 62. Sliding columns 64 slidably engaged with the support frame 62 are fixedly connected to the four corners of the edge of the support frame 62. A limiting baffle 641 is fixedly connected to the side of the sliding column 64 away from the support frame 62. A second spring 65 is fixedly installed between the support frame 62 and the fixed frame 61. Since the limiting piece 44 and the slot are in clearance fit, when the upper baking tray 4 is assembled, the abutting plane 47 of the upper baking tray 4 will contact the limiting block 63, and under the action of the second spring 65, the limiting block 63 pushes the upper baking tray 4 to move outwards until the limiting piece 44 abuts against at least one inner wall of the slot, avoiding the situation that the limiting piece 44 offsets in the slot during use and improving the use effect.

[0048] Furthermore, as Figure 6As shown, a guiding arc surface is provided on one side edge of the limiting block 63 away from the support frame 62. After the limiting piece 44 of the upper baking tray 4 is inserted into the slot of the limiting seat 25, the abutting plane 47 of the upper baking tray 4 can contact and compress the second spring 65 along the guiding arc surface until it contacts and abuts against the surface of the limiting block 63 under the action of the second spring 65, making the assembly safer and more efficient.
