Description

Technical Field

[0001] This application relates to the field of household appliances, and more specifically, to an oven. Background Technology

[0002] Most pizza ovens in related technologies do not have rotating trays, which hinders even heating of the food. Based on existing solutions, a pizza oven with a rotating tray is proposed. This oven includes a motor, a main shaft, and a rotating tray, with the main shaft driving the rotating tray to rotate under the motor's influence. However, to ensure the stability of the main shaft installation and prevent tray wobbling, the support structure for the main shaft is designed to be complex, resulting in higher cost, larger space occupation, and hindering compact product design.

[0003] Therefore, simplifying the main shaft installation structure of the pizza oven has become an urgent problem to be solved. Utility Model Content

[0004] The present invention aims to at least solve the technical problems of existing or related technologies, such as the complex main shaft support installation structure, high cost, large space occupation, and unfavorable to the compact design of pizza ovens with rotating trays.

[0005] The first aspect of this utility model is to provide an oven.

[0006] This utility model provides an oven, comprising: a support frame with a first through hole; a rotating tray rotatably disposed on one side of the support frame; a bearing located between the rotating tray and the support frame, the bearing having a shaft hole; a main shaft, the first end of the main shaft passing through the shaft hole and the first through hole in sequence and then connected to the rotating tray; a support limiting member located on the side of the support frame away from the rotating tray, the support limiting member having a through hole; and a drive device including a drive shaft; wherein, the second end of the main shaft passes through the through hole and is connected to the drive shaft.

[0007] The oven provided by this utility model can specifically be a pizza oven or similar product. This type of oven, by setting a bearing between the rotating tray and the support frame, together with a support limiting component on the other side of the support frame, supports the main shaft. The drive shaft is directly connected to the main shaft, eliminating the double-bearing structure of related solutions. The combination of bearings and support limiting components ensures excellent support stability of the main shaft during rotation, preventing wobbling of the main shaft due to bearing clearance and ensuring smooth rotation of the rotating tray. Furthermore, this structure makes the overall product structure relatively simple, which helps reduce installation costs, simplifies the overall structure, and facilitates the miniaturization and compact design of the oven.

[0008] In any of the above embodiments, optionally, the supporting limiting member includes a baffle, the baffle including a fixing part and a limiting part connected to each other, the limiting part being provided with a through hole. The fixing part is fixedly installed on the bracket by a threaded connector.

[0009] In this embodiment, the supporting limiting member specifically includes a baffle. The baffle includes a fixing part for fixing the baffle, and the limiting part is provided with a through hole. The limiting part is sleeved on the main shaft based on the through hole, which can achieve stable support for the main shaft. The fixing part may be provided with mounting holes to facilitate fixing the fixing part to the bracket using threaded connectors. This structure makes the supporting limiting member plate-shaped, with a relatively simple structure, which helps reduce product installation costs, simplifies the overall product structure, and facilitates the miniaturization and compact design of the oven.

[0010] In any of the above embodiments, optionally, there are two fixing parts, which are symmetrically arranged around the periphery of the limiting part. Along the axial direction of the main shaft, the two fixing parts are located on the same side of the limiting part and are connected to the limiting part in a stepped manner.

[0011] In this embodiment, two fixing parts are symmetrically arranged on both sides of the periphery of the limiting part and are fixedly installed on the bracket by threaded connectors or the like. The fixing parts are relatively high, facilitating operations such as screwing. This arrangement also allows the limiting part to maintain a certain distance from the bottom of the bracket, thereby providing better support and limiting of the spindle, further ensuring the installation stability of the spindle, preventing wobbling due to bearing clearance, and ensuring the smooth rotation of the rotating tray.

[0012] In any of the above embodiments, optionally, the oven further includes: a heat insulation cover, which is disposed on the outside of the drive device, and the heat insulation cover is provided with a third through hole for the drive shaft to extend out; and a base, which is mounted on the side of the bracket away from the rotating tray, the drive device is mounted below the base, and the bottom of the base surrounds the heat insulation cover.

[0013] In this embodiment, by setting a heat shield, excessive heat transfer to the drive device can be prevented, thus providing heat insulation protection for the drive device. This improves the service life of the drive device and reduces the probability of damage due to overheating. The heat shield also has a third through hole through which the drive shaft extends and connects to the main shaft; that is, the connection point between the main shaft and the drive shaft is located outside the heat shield. The drive device can specifically be a motor.

[0014] Furthermore, the oven also includes a base, which is mounted on the lower part of the support and surrounds the heat insulation cover. An installation space can be formed between the base and the support to facilitate the installation of couplings, adapters, etc.

[0015] In any of the above embodiments, the oven may optionally include a universal joint coupling for connecting the second end of the drive shaft and the main shaft.

[0016] In this embodiment, the oven also includes a coupling, which may specifically be a universal joint coupling. The universal joint coupling can compensate for concentricity errors that occur during the installation of the drive shaft, preventing excessive resistance to the drive unit during operation.

[0017] In any of the above embodiments, the oven may optionally include: an adapter, wherein the drive shaft includes a D-shaped connector, and the D-shaped connector is connected to a second end of the main shaft via the adapter.

[0018] In this embodiment, the coupling and the drive shaft are connected via an adapter, facilitating the maintenance and replacement of the drive unit. Specifically, to ensure that the D-shaped connecting end connects to the second end of the spindle via the adapter, the adapter is provided with a D-shaped connecting hole that mates with the D-shaped connecting end.

[0019] Of course, if there is no D-shaped connector on the drive shaft, the adapter can be removed, allowing the drive shaft to be directly connected to the coupling.

[0020] In any of the above embodiments, optionally, the rotating tray is detachably mounted on the bracket and detachably connected to the first end of the spindle.

[0021] In this embodiment, the bottom of the rotating tray can be easily cleaned by disassembling it, ensuring that the rotating tray is clean and hygienic during use and improving the user experience.

[0022] In any of the above embodiments, optionally, a second through hole is provided on the rotating tray; the oven also includes a locking nut, the first end of the spindle extends out of the second through hole after passing through the first through hole, the locking nut is detachably installed on the first end of the spindle, and is limited to the side of the rotating tray away from the bracket.

[0023] In this embodiment, the first end of the spindle passes upward through the bracket and the rotating tray, and is then fixed to the rotating tray by a locking nut, thereby achieving a locking between the spindle and the rotating tray. When it is necessary to disassemble the rotating tray, the locking nut can be rotated to remove it from the spindle, releasing the restriction between the spindle and the rotating tray, allowing the rotating tray to be freely disassembled.

[0024] In any of the above embodiments, the locking nut may optionally be a butterfly nut.

[0025] In this embodiment, the butterfly nut is a standard part, which is relatively easy to procure, thus reducing the overall cost of the product. Furthermore, the butterfly nut is easy for users to tighten, improving the ease of assembly and disassembly of the rotating tray.

[0026] In any of the above embodiments, optionally, a recessed portion is provided on the side of the rotating tray away from the support, which is recessed towards the support, and the locking nut is located in the recessed portion.

[0027] In this embodiment, the locking nut does not protrude from the non-recessed surface of the rotating tray along the axial direction of the main shaft. This structure ensures that the rotating tray forms a large support plane, facilitating the baking and heating of larger ingredients such as pizzas.

[0028] In any of the above embodiments, optionally, the bracket includes an inner bottom plate and a bottom shell connected to each other, a rotating tray is mounted on the inner bottom plate, the bottom shell is disposed on the side of the inner bottom plate away from the rotating tray, a bearing is mounted between the inner bottom plate and the rotating tray, and a support limiting member is mounted on the bottom of the side of the bottom shell away from the inner bottom plate.

[0029] Furthermore, the oven also includes a retaining nut and a washer. The retaining nut is mounted on the main shaft, located on the side of the bearing away from the rotating tray, and abuts against the bearing. The washer is sleeved on the main shaft, located between the retaining nut and the washer. The retaining nut and the washer are installed between the bottom shell and the inner bottom plate.

[0030] In this embodiment, the inner base plate is mainly used to support the bearing and the rotating tray. The bottom shell is mainly used to limit and fix nuts and washers, etc. The fixing nuts and washers can cooperate with the bearing to lock the main shaft, prevent the main shaft from moving axially, and make it more convenient to disassemble the rotating tray by making it less likely to pull the drive device through the main shaft.

[0031] In any of the above embodiments, optionally, a mounting groove is provided on the bracket, and the rotating tray is installed in the mounting groove.

[0032] In this embodiment, by providing a mounting groove on the bracket, the rotating tray can be confined within the mounting groove, which helps to improve the installation stability of the rotating tray.

[0033] Optionally, the oven is a pizza oven, and the rotating tray is a pizza stone tray. Of course, the oven can also be used to bake other foods, so the oven is not limited to a pizza oven.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] The following reference Figure 1 , Figure 2 and Figure 3 The oven provided in the embodiments of this application will be described below.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides an oven, including a support 80, a rotating tray 1, a main shaft 2, a drive device 3, a support and limiting member 4, and a bearing 5. The support 80 has a first through hole 842. The rotating tray 1 is rotatably mounted on one side of the support 80 for holding food. The bearing 5 is located between the rotating tray 1 and the support 80, and has a shaft hole 52. The first end of the main shaft 2 passes through the shaft hole 52 and the first through hole 842 in sequence before connecting to the rotating tray 1. The support and limiting member 4 is located on the side of the support 80 away from the rotating tray 1, and has a through hole 4242. The drive device 3 includes a drive shaft 32. The second end of the main shaft 2 passes through the through hole 4242 and is connected to the drive shaft 32.

[0045] The oven provided by this utility model can specifically be a pizza oven or similar product. This oven, by setting a bearing 5 between the rotating tray 1 and the support 80, together with a support limiting member 4 on the other side of the support 80, supports the main shaft 2. The drive shaft 32 is directly connected to the main shaft 2. This eliminates the need for the double-bearing structure in related solutions. The combination of bearing 5 and support limiting member 4 ensures excellent support stability for the main shaft 2 during rotation, preventing wobbling due to bearing clearance and ensuring smooth rotation of the rotating tray 1. Furthermore, this structure simplifies the overall product structure, reducing installation costs and facilitating miniaturization and compact design of the oven.

[0046] Optionally, the drive device 3 is a motor, and the drive shaft 32 is the motor shaft.

[0047] In any of the above embodiments, optionally, as Figure 1 As shown, the support limiting member 4 includes a baffle 42, which includes a fixing part 422 and a limiting part 424 connected to each other. The limiting part 424 is provided with a through hole 4242. The fixing part 422 is fixedly installed on the bracket 80 by a threaded connector.

The baffle 42 includes a fixing part 422 for fixing the baffle 42, and a limiting part 424 is provided with a through hole 4242. The limiting part 424 is sleeved and installed on the main shaft 2 based on the through hole 4242, which can achieve stable support for the main shaft 2. The fixing part 422 can be provided with a mounting hole to facilitate fixing the fixing part 422 to the bracket 80 by means of a threaded connector. This structure makes the supporting limiting member 4 plate-shaped, and its structure is relatively simple, which helps to reduce the installation cost of the product, simplify the overall structure of the product, and facilitate the miniaturization and compact design of the oven.

[0049] In any of the above embodiments, optionally, as Figure 1As shown, there are two fixing parts 422. The two fixing parts 422 are symmetrically arranged around the periphery of the limiting part 424. Along the axial direction of the main shaft 2, the two fixing parts 422 are located on the same side of the limiting part 424 and are connected to the limiting part 424 in a stepped manner.

[0050] In this embodiment, two fixing parts 422 are symmetrically arranged on both sides of the periphery of the limiting part 424 and are fixedly installed on the bracket 80 by threaded connectors or the like. The fixing parts 422 are relatively high, facilitating operations such as screwing. Simultaneously, this arrangement allows the limiting part 424 to maintain a certain distance from the bottom of the bracket 80, thereby providing better support and limiting of the spindle 2, further ensuring the installation stability of the spindle 2, preventing wobbling due to bearing clearance, and ensuring the smooth rotation of the rotating tray 1.

[0051] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 3 As shown, the oven also includes a heat insulation cover 6, which covers the outside of the drive unit 3.

A base 82 is mounted on the side of the bracket 80 away from the rotating tray 1, and the drive unit 3 is mounted below the base 82. The bottom of the base 82 surrounds the heat insulation cover 6.

[0052] In this embodiment, by providing a heat shield 6, excessive heat transfer to the drive device 3 can be prevented, thus providing heat insulation protection for the drive device 3. This improves the service life of the drive device 3 and reduces the probability of damage due to overheating. The heat shield 6 also has a third through hole 63 through which the drive shaft 32 extends and connects to the main shaft 2. In other words, the connection point between the main shaft 2 and the drive shaft 32 is located outside the heat shield 6.

[0053] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the oven also includes a base 82, which is mounted on the lower part of the support 80 and surrounds the heat insulation cover 6. An installation space can be formed between the base 82 and the support 80 to facilitate the installation of couplings, adapters 74, etc.

[0054] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 3 As shown, the oven also includes a universal joint coupling 72 for connecting the drive shaft 32 and the second end of the main shaft 2.

[0055] In this embodiment, the oven also includes a coupling, which may specifically be a universal joint coupling 72. The universal joint coupling 72 can compensate for the concentricity error generated during the installation of the drive shaft 32, preventing excessive resistance experienced by the drive device 3 during operation.

[0056] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 3 As shown, the oven also includes: an adapter 74, and a drive shaft 32 including a D-shaped connector 322, which is connected to the second end of the main shaft 2 via the adapter 74.

[0057] In this embodiment, the coupling and the drive shaft 32 are connected by an adapter 74, which facilitates the maintenance and replacement of the drive device 3. In order to ensure that the D-shaped connecting end 322 is connected to the second end of the main shaft 2 through the adapter 74, the adapter 74 is provided with a D-shaped connecting hole that mates with the D-shaped connecting end 322.

[0058] Of course, if there is no D-shaped connector 322 on the drive shaft 32, the adapter 74 can be removed, allowing the drive shaft 32 to be directly connected to the coupling.

[0059] In any of the above embodiments, optionally, the rotating tray 1 is detachably mounted on the bracket 80 and detachably connected to the first end of the spindle 2.

[0060] In this embodiment, by disassembling the rotating tray 1, the bottom of the rotating tray 1 can be easily cleaned, ensuring that the rotating tray 1 is clean and hygienic during use and improving the user experience.

[0061] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 3 As shown, the rotating tray 1 is provided with a second through hole 12; the oven also includes a locking nut 92, the first end of the main shaft 2 extends out through the second through hole 12 after passing through the first through hole 842, the locking nut 92 is detachably installed on the first end of the main shaft 2 and is limited to the side of the rotating tray 1 away from the bracket 80.

[0062] In this embodiment, the first end of the spindle 2 passes upward through the bracket 80 and the rotating tray 1, and is then fixedly mounted on the rotating tray 1 by a locking nut 92, thereby achieving locking between the spindle 2 and the rotating tray 1. When it is necessary to disassemble the rotating tray 1, the locking nut 92 can be rotated to remove it from the spindle 2, thereby releasing the restriction between the spindle 2 and the rotating tray 1, allowing the rotating tray 1 to be freely disassembled.

[0063] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 3 As shown, the locking nut 92 is a butterfly nut 922.

[0064] In this embodiment, the butterfly nut 922 is a standard part, which is relatively easy to procure, thus reducing the overall cost of the product. Furthermore, the butterfly nut 922 is easy for users to tighten and loosen, improving the ease of assembly and disassembly of the rotating tray 1.

[0065] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 3 As shown, a recessed portion 14 is provided on the side of the rotating tray 1 away from the bracket 80, which is recessed towards the bracket 80, and the locking nut 92 is located in the recessed portion 14.

[0066] In this embodiment, the locking nut 92 does not protrude from the non-recessed surface of the rotating tray 1 along the axial direction of the main shaft 2. This structure ensures that the rotating tray 1 forms a large support plane, which is convenient for baking and heating larger ingredients such as pizzas.

[0067] In any of the above embodiments, optionally, the bracket 80 includes an inner bottom plate 84 and a bottom shell 86 connected to each other, the rotating tray 1 is mounted on the inner bottom plate 84, the bottom shell 86 is disposed on the side of the inner bottom plate 84 away from the rotating tray 1, the bearing 5 is mounted between the inner bottom plate 84 and the rotating tray 1, and the support limiting member 4 is mounted on the bottom of the side of the bottom shell 86 away from the inner bottom plate 84.

[0068] Furthermore, the oven also includes a fixing nut 94 and a washer 96. The fixing nut 94 is mounted on the main shaft 2, located on the side of the bearing 5 away from the rotating tray 1, and abuts against the bearing 5. The washer 96 is sleeved on the main shaft 2, located between the fixing nut 94 and the washer 96. The fixing nut 94 and the washer 96 are installed between the bottom shell 86 and the inner bottom plate 84.

[0069] In this embodiment, the inner bottom plate 84 is mainly used to support the bearing 5 and the rotating tray 1. The bottom shell 86 is mainly used to limit and fix the nut 94 and the washer 96, etc. The fixing nut 94 and the washer 96 can cooperate with the bearing 5 to lock the main shaft 2, prevent the main shaft 2 from moving axially, and make it more convenient to disassemble the rotating tray 1 by preventing the main shaft 2 from pulling the drive device 3, etc.

[0070] In any of the above embodiments, optionally, a mounting groove 88 is provided on the bracket 80, and the rotating tray 1 is installed in the mounting groove 88.

[0071] In this embodiment, by providing a mounting groove 88 on the bracket 80, the rotating tray 1 can be confined within the mounting groove 88, which helps to improve the installation stability of the rotating tray 1.

[0072] Optionally, the bottom of the mounting groove 88 forms an inner bottom plate 84.

[0073] Optionally, the oven is a pizza oven, and the rotating tray 1 is a pizza stone tray. Of course, the oven can also be used to bake other foods, so the oven is not limited to a pizza oven.

[0074] Optionally, the base 82 is provided with a receiving groove 822 to accommodate the adapter 74, the universal joint coupling 72, etc.

[0075] The following reference Figure 1 , Figure 2 and Figure 3 Let me introduce a rotating structure for a pizza stone tray.

[0076] This embodiment discloses a rotating structure for a pizza stone tray used in a pizza oven. The structure of the rotating structure of the pizza stone tray is as follows: Figure 1 , Figure 2 and Figure 3 As shown. This pizza stone tray rotating mechanism has an overall top-to-bottom structure: from top to bottom, the components are: butterfly nut, pizza stone tray, main shaft, bearing, bracket, gasket, flange nut, bottom shell, swing baffle, universal joint, D-type adapter, base, motor cover, motor, etc.

[0077] In a compact oven layout, the rotating mechanism of the pizza stone tray needs to withstand temperatures up to 600°C while ensuring a smooth and stable rotation process, and the tray can be easily disassembled for easy cleaning.

[0078] The technical means are as follows:

[0079] The smooth rotation is primarily achieved through bearings. The tray's horizontal rotation is ensured by the bearings being horizontally riveted to the bracket. The tray is secured by the spindle and butterfly nuts. The spindle fits into the inner ring of the bearing and is locked in place by washers and flange nuts, ensuring smooth rotation. The butterfly nut at the top is ergonomically designed for easy twisting, facilitating tray removal and cleaning. The center hole of the swing baffle mates concentrically with the lower end of the spindle, limiting spindle movement. The swing baffle is fixed to the bottom of the housing to prevent wobbling caused by bearing clearance. After the spindle and swing baffle mate, the protruding part connects to a universal joint. The universal joint's role in this structure is primarily to compensate for concentricity errors during motor installation, preventing excessive resistance to the motor during operation. The universal joint connects to the motor via a D-type adapter, facilitating motor maintenance and replacement.

[0080] Related technologies with structures similar to this embodiment often use dual bearings to ensure smooth rotation. However, the dual bearing structure is more expensive and occupies more space than the rotating structure of the pizza stone tray in this embodiment, making it very unsuitable for compact ovens and less convenient to disassemble.

[0081] Pallet section: The pallet is locked in place by the upper thread of the spindle and the butterfly nut. The butterfly nut is easy to remove and also ensures that the pallet is easy to clean.

[0082] Bearing section: The main shaft itself has an upper baffle, and the lower thread of the main shaft can fully lock the bearing by cooperating with the flange nut gasket, so that the bearing does not move up and down, and is constrained by the swing baffle to prevent it from swaying left and right, ensuring the smooth rotation of the tray.

[0083] Drive section: The drive section mainly consists of a motor, D-type adapter, motor cover and universal joint. The motor provides the main power, the motor cover has the functions of fixing the motor and heat insulation, the D-type adapter connects the universal joint and the motor output shaft, and the universal joint has a special structure that can compensate for the eccentricity error caused during motor installation, ensuring the motor can work under normal load.

[0084] The pizza stone tray rotating mechanism in this embodiment uses more standard parts to achieve the same effect, thus greatly reducing the installation difficulty and cost of the pizza stone tray rotating mechanism.

[0085] In the description of this specification, the terms "connection," "installation," and "fixing," etc., should be interpreted broadly.
