Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a double-door oven. Background Art

[0002] An oven is a sealed appliance used for baking or drying food. Traditional ovens typically feature a single, manual, pull-down door. This requires the user to manually pull down the door handle to open the door. This causes heat to escape upward, posing a risk of burns to the user's face. Furthermore, the large pull-down door requires a large movement when opening and closing, taking up considerable operating space.

[0003] To address this issue, Chinese Patent No. CN214072970U discloses a double-door oven, comprising: an oven body, wherein a heating chamber is provided within the oven body, the heating chamber being open at the front end; a left door panel movably mounted on the oven body; and a right door panel movably mounted on the oven body, cooperating with the left door panel to open and close the heating chamber opening. When the heating chamber opening is closed, a gap is defined between the opposing end surfaces of the left and right door panels, and a seal is provided between the left and right door panels to seal the gap. This prior art technique employs a sealant in the gap between the left and right door panels. While this seal prevents heat loss and thus affects the oven's heating efficiency, it also prevents heat from escaping and potentially scalding the user. However, this double-door oven structure closes too quickly, making it easy for the user's hand to be pinched. The lack of protective measures results in low safety and a poor user experience. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a double-door oven, which can slow down the door closing speed and has good safety.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a double-door oven, comprising an oven body, a face frame provided at the opening of the oven body, and two door body assemblies, the two door body assemblies being hinged to the left and right sides of the face frame respectively through door shafts, the double-door oven also comprising two door rotation mechanisms, the door rotation mechanisms comprising a fixing seat, a compression spring, a pulley, and a rotating wheel having an inclined convex portion, the rotating wheel being mounted on the upper end of the door shaft and rotating coaxially with the door shaft;

[0006] The fixed seat is installed on the inner side of the upper part of the face frame. The compression spring, pulley and rotating wheel are all located in the fixed seat. The pulley is connected to one end of the fixed seat through the compression spring.

[0007] During the process of opening and closing the door, the pulley contacts the inclined convex portion; when the door body assembly is at the maximum door opening angle, the rear end of the inclined convex portion abuts against the pulley, so that the door body assembly remains paused at the maximum door opening angle; when the door body assembly is closed, the front end of the inclined convex portion abuts against the pulley, so that the door body assembly remains paused when closing.

[0008] A double-door oven provided in this technology adopts a door rotation mechanism to slow down the opening and closing speed of the door assembly, which can slow down the closing speed of the door assembly, solve the problem of fingers being pinched when closing the door quickly in the prior art, and is safer; and through the structure in which the inclined convex portion of the rotating wheel abuts against the pulley, the door assembly can be paused when the door assembly is at the maximum opening angle and in the closed state, with safe and reliable performance and good user experience; at the same time, the structure of the above-mentioned door rotation mechanism is compact and simple, with low manufacturing cost and easy operation.

[0009] In a preferred technical solution, a cavity is provided in the oven body, and the inner walls on both sides of the cavity are provided with slides for placing the grill, and a limiting component is provided above one end of the slide close to the cavity opening; one end of the limiting component is bent downward and extends into the grill, and is used to clamp the rear frame of the grill when the grill is pulled out to prevent the grill from falling.

[0010] This technology can limit the grill by setting a limiting component above the slide groove in the cavity to prevent the grill from falling when it is pulled out.

[0011] In a preferred technical solution, the inner wall of the cavity is provided with a raised strip above the chute; the limiting component is a bent bracket, one end of which is bent upward and fixed to the top surface of the raised strip, and the other end of which is bent downward to form a limiting buckle, the end of which is located inside the grill. This technology uses a bent bracket as the limiting component, which has a simple structure, low manufacturing cost, and is easy to install and remove.

[0012] In a preferred technical solution, the door assembly includes a door hinge, a door support plate, a door panel, a door handle clamp, and a door handle. The door support plate is hinged to the left and right sides of the face frame via the door hinge, and the ends of the door panel are fixedly connected to the door support plate and the door handle clamp, respectively. The door handle clamp is mounted on the door handle. Both door assemblies in this technology use a door structure consisting of a door hinge, a door support plate, a door panel, a door handle clamp, and a door handle, resulting in a simple structure and easy installation and maintenance.

[0013] In a preferred embodiment, the inner side of the door support plate is provided with a support portion for supporting the pulled-out grill.

[0014] In a preferred technical solution, flattened portions are provided at both ends of the door shaft, and flattened grooves cooperating with the flattened portions are provided on the door support plate; the door support plate is connected to the door shaft in a limiting manner through the flattened grooves.

[0015] In this technology, the door support plate is installed on the flat part of the door shaft through the flat groove, forming a limited matching installation, which can effectively prevent the door support plate from shifting up and down, and the structure is more solid and stable.

[0016] In a preferred technical solution, a mounting groove is provided at the axis of the rotating wheel, and the inner side surface of the mounting groove has a flat recess that cooperates with the flat portion; the rotating wheel is installed on the upper end of the door shaft through the mounting groove.

[0017] In this technology, the rotating wheel is connected to the upper end of the door shaft through a mounting groove provided with a flat recess, and can easily achieve coaxial rotation with the rotating shaft.

[0018] In a preferred technical solution, the top of the inclined convex portion is a slope that is lower in the front and higher in the back, and both ends of the slope are arc angles; during the door opening and closing process, the pulley maintains contact with the slope, which facilitates slowing down the door closing speed.

[0019] In a preferred technical solution, the maximum opening angle range of the door assembly is 110° to 120°, so as to leave sufficient angular space for users to take food into and out of the oven; the opening angle range when the door assembly enters the automatic closing state is 10° to 15°, which can realize automatic and slow door opening to prevent fingers from being pinched and provide better safety.

[0020] In a preferred technical solution, the door panel is made of glass, which facilitates observation of the oven cavity.

[0021] It can be seen from the above technical solutions that, compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a double-door oven, which adopts a door rotation mechanism to slow down the opening and closing speed of the door assembly, and can slow down the closing speed of the door assembly, solving the problem of fingers being pinched by rapid door closing in the prior art, and is safer; and through the structure in which the inclined convex portion of the rotating wheel abuts against the pulley, the door assembly can be paused when the door assembly is at the maximum door opening angle and closed state, with safe and reliable performance and good user experience; at the same time, the structure is simple and easy to operate.

[0036] Reference Figure 1-9 A double-door oven according to an embodiment of the present invention is described.

[0037] In one embodiment, Figure 1-8 As shown, a double-door oven includes an oven body, a face frame 1 provided at the opening of the oven body, and two door body assemblies 2. The two door body assemblies 2 are hinged to the left and right sides of the face frame 1 through door shafts 21 respectively.

[0038] In the application scenario of this embodiment, the oven body of the double-door oven may also include a body shell 8 and a control panel 7. The control panel 7 is arranged on the outer surface of the body shell 8. The specific position is not limited. It can be arranged on the same side as the two door body assemblies 2, or it can be arranged at other positions.

[0039] The double-door oven further comprises two door rotating mechanisms 3, which include a fixing seat 31, a compression spring 32, a pulley 33 and a rotating wheel 34 having an inclined convex portion 341. The rotating wheel 34 is mounted on the upper end of the door shaft 21 and rotates coaxially with the door shaft 21.

[0040] The fixing seat 31 is installed on the upper inner side of the face frame 1 . The compression spring 32 , the pulley 33 and the rotating wheel 34 are all located in the fixing seat 31 . The pulley 33 is connected to one end of the fixing seat 31 through the compression spring 32 .

[0041] During the door opening and closing process, the pulley 33 comes into contact with the inclined convex portion 341 .

[0042] When the door assembly 2 is at the maximum door opening angle, the rear end of the inclined convex portion 341 abuts against the pulley 33, so that the door assembly 2 remains paused at the maximum door opening angle.

[0043] When the door assembly 2 is closed, the front end of the inclined convex portion 341 abuts against the pulley 33, so that the door assembly 2 remains stopped when closing.

[0044] The two door assemblies 2 are opened and closed independently, and the user can open one of the door assemblies 2 individually or open both door assemblies 2 in pairs. In a specific implementation, since the force required to stop the door assembly 2 at its maximum opening angle is greater than that required to stop the door, the front end of the inclined convex portion 341 can be set lower than the rear end, so that the higher rear end of the inclined convex portion 341 can abut against the pulley 33, thereby achieving a more stable door opening stop.

[0045] In one embodiment of this invention, the top of the inclined convex portion 341 is a slope that is lower at the front and higher at the back, with both ends of the slope having arc angles. During the door opening and closing process, the pulley 33 maintains contact with the slope. In this embodiment, the front end of the slope is the high end, and the rear end is the low end, with the entire slope gradually decreasing from front to back.

[0046] The working principle of the above-mentioned double-door oven is as follows: when the oven door is opened or closed, the rotating wheel 34 assembled on the upper end of the door shaft 21 drives its inclined convex portion 341 to rotate, forming a rotation track.

[0047] like Figure 3-5 As shown, during the door opening process, the left and right wheels 34 rotate in the direction of the door assembly 2 when it is opened, and the pulley 33 is always in contact with the inclined convex portion 341 under the thrust of the compression spring 32 until the door assembly 2 reaches the maximum door opening angle. The rear end of the inclined convex portion 341 of the wheel 34 abuts against the outer side of the pulley 23, achieving a limited pause at the maximum door opening angle. Among them, the door rotating mechanism 3 is located at Figure 3 The decomposition structure of the I position is as follows: Figure 4 As shown, Figure 4 The arrows near the middle door shaft 21 and the rotating wheel 34 indicate the direction of rotation of the door assembly 2 for opening the door, and the arrow below the compression spring 32 indicates its direction of movement; Figure 5 The middle arrow indicates the door opening rotation direction of the door assembly 2.

[0048] like Figure 6-8As shown, during the door closing process, the left and right wheels 34 rotate in the direction of the door assembly 2 when it is closed; the pulley 33 is always in contact with the inclined convex portion 341 under the thrust of the compression spring 32, applying resistance to the inclined convex portion 341, which can enable the door assembly 2 to close slowly; when the door assembly 2 is completely closed, the front end of the inclined convex portion 341 of the wheel 34 abuts against the inner side of the pulley 33, which can achieve a pause in closing the door and keep the door assembly 2 tightly closed in the face frame 1, that is, the door assembly 2 is tightly closed in the closed state. Among them, the door rotation mechanism 3 is located at position II, and the decomposition structure of position II is as shown in FIG. Figure 7 As shown, Figure 7 The arrows near the middle door shaft 21 and the rotating wheel 34 indicate the direction of rotation of the door assembly 2 for closing the door, and the arrow below the compression spring 32 indicates its direction of movement; Figure 8 The middle arrow indicates the closing rotation direction of the door assembly 2.

[0049] The maximum opening angle range of the door body assembly 2 can be 110° to 120°; the opening angle range when the door body assembly 2 enters the automatic closing state can be 10° to 15°. When closing the door, when the door opening angle between the door body assembly 2 and the face frame 1 is 10° to 15°, the door enters the automatic closing state. At this time, the rotating wheel 34 rotates backward, and the end of the slope at the top of the inclined protrusion 341 contacts the pulley 33. Since the slope gradually increases from front to back, the part in contact with the pulley 33 gradually narrows. The pulley 33 moves forward under the thrust of the compression spring 32, and continues to push the inclined protrusion 341, thereby realizing the automatic closing of the door body assembly 2.

[0050] In this embodiment, a cavity is provided in the oven body, and the inner walls on both sides of the cavity are provided with slide grooves 5 for placing the grill 4. A limiting component 6 is provided above one end of the slide groove 5 close to the cavity opening; one end of the limiting component 6 is bent downward and extends into the grill 4, and is used to clamp the rear frame of the grill 4 when the grill 4 is pulled out to prevent the grill 4 from falling.

[0051] The chute 5 is used to place the grill 4, and a limiting component 6 is set above each chute 5 on both sides of the cavity to limit the grill 4 and prevent the grill 4 from falling when it is pulled out.

[0052] In specific implementation, when the user pulls the grill 4 out of the slide slot 5, the rear frame of the grill 4 will be stuck by the limiting components 6 on the left and right sides, which can effectively stop the grill 4 from moving outward and prevent the grill 4 from falling out of the cavity.

[0053] In this embodiment, the inner wall of the cavity is provided with a convex strip above the slide groove 5; the limiting component 6 is a bending bracket, one end of the bending bracket is bent upward and fixed on the top surface of the convex strip, and the other end of the bending bracket is bent downward to form a limiting buckle, and the end of the limiting buckle is located inside the grill 4.

[0054] The bent bracket can be an integrally formed structure consisting of an upper bent portion, a middle connecting portion, and a lower bent portion. The upper and lower bent portions are perpendicular to the middle connecting portion, forming a Z-shape. A certain distance is maintained between the lower bent retaining clip and the top surface of the ridge, allowing a certain range of motion for the grill 4. In practice, the distal end of the retaining clip is always located within the frame of the grill 4. Each time the grill 4 is withdrawn, it is stopped by the retaining clips on both sides, preventing it from falling.

[0055] In this embodiment, if Figure 9 As shown, the door body assembly 2 includes a door shaft 21, a door support plate 22, a door panel 23, a door handle clamp 24 and a door handle 25; the door support plate 22 is hinged to the left and right sides of the face frame 1 through the door shaft 21, and the two ends of the door panel 23 are respectively fixedly connected to the door support plate 22 and the door handle clamp 24, and the door handle 25 is installed on the door handle clamp 24.

[0056] In the above embodiment, the inner side of the door support plate 22 is provided with a support portion 26 for supporting the withdrawable grill 4. The number of support portions 26 can be one or more, and the number can be determined by the number of chutes 5 in the oven body that can accommodate grills 4. In other words, a support portion 26 can be provided at a position corresponding to the exit of each chute 5.

[0057] In a specific implementation, the inner side surface of the door support plate 22 may be provided with a plurality of support portions 26 from top to bottom for supporting the grills 4 at different heights. The grills 4 may rest on the support portions 26 when being pulled out.

[0058] In the above embodiment, the door hinge 21 is provided with flattened portions 210 at both ends, and the door support plate 22 is provided with flattening grooves that mate with the flattened portions 210. The door support plate 22 is connected to the door hinge 21 via the flattening grooves in a position-limiting manner. The flattened portions 210 are located near the distal end of the door hinge 21. The circular shaft of the door hinge 21 is also located above and below the flattened portions 210. The diameter of the flattened portions 210 is larger than that of the door hinge 21, thereby conveniently achieving a position-limiting, fixed installation of the door support plate 22.

[0059] In the above embodiment, a mounting groove 342 is provided at the axis of the rotating wheel 34 , and the inner side surface of the mounting groove 342 has a flat recess that cooperates with the flat portion 210 ; the rotating wheel 34 is installed on the upper end of the door shaft 21 through the mounting groove 342 .

[0060] The mounting groove 342 of the rotating wheel 34 engages with the circular shaft of the door shaft 21 at its upper portion and with the flat portion 210 at its lower portion, enabling the rotating wheel 34 to rotate coaxially with the door shaft 21. In practice, the mounting groove 342 can be either a through-groove or a non-through-groove. When the door is opened or closed, the door shaft 21 rotates, and the flat portion 210 of the door shaft 21 applies force to the flat recessed portion inside the mounting groove 342, driving the rotating wheel 34 to rotate coaxially with the door shaft 21.

[0061] In the above embodiment, the door panel 23 is made of glass. The door panel 23 can be made of high-temperature resistant glass so that the user can see the food baking status through the door panel 23 in time.
