Description

Technical Field

[0001] This utility model relates to the field of ovens, and more particularly to an oven with an adjustable temperature heating channel structure that allows for the reuse of heat. Background Technology

[0002] An oven is a common household appliance, primarily used for baking and roasting. Larger ovens used in industrial processes have significantly larger baking spaces than ordinary ovens. To maintain a stable and even temperature inside the oven to meet baking requirements, the heating elements typically need to continuously output higher temperatures. However, once the oven temperature stabilizes, only a portion of the heat released by the heating elements is used to maintain this temperature; the remainder is dissipated through fans or other means to prevent overheating and damage. Therefore, ovens often experience significant heat waste during operation.

[0003] In the prior art, a utility model with patent publication number CN210802026U provides a novel high-temperature oven capable of recovering and utilizing heat. It includes a viewing window embedded inside a sealed cover, rollers installed at the corner of the lower surface of the oven body, and a tray disposed inside the oven body. A heat-collecting component is provided on one side of the oven body, and a support component is connected below the tray. The heat-collecting component stores heat from inside the oven body in a water tank, thereby converting cold water in the tank into hot water for use, improving heat utilization and reducing heat loss.

[0004] While the aforementioned oven utilizes heat secondaryly, it adds a water tank unrelated to the oven's primary function, increasing the oven's usable space. Furthermore, when the water temperature rises to a certain level, its heat absorption efficiency decreases significantly, hindering the oven's heat dissipation. Summary of the Invention

[0005] In view of this, the present invention provides an oven with an adjustable temperature heating channel structure that allows for the reuse of heat to solve the above problems.

[0006] An oven with an adjustable temperature heating channel structure and reusable heat includes a storage unit, a high-temperature unit disposed on one side of the storage unit, and a low-temperature unit fixedly disposed on one side of the high-temperature unit. The high-temperature unit includes a high-temperature chamber disposed on the storage unit, a heating plate fixedly disposed on the top of the high-temperature chamber, and at least one heat outlet disposed on the top of the high-temperature chamber. The low-temperature unit includes a low-temperature chamber fixedly disposed on the high-temperature unit, an outer shell disposed outside the low-temperature chamber, a spacer layer located between the low-temperature chamber and the outer shell, a heating channel located between the spacer layer and the low-temperature chamber, a first temperature regulating component disposed within the heating channel, and a second temperature regulating component disposed on the outer shell. A first heat inlet and a second heat inlet are provided on the low-temperature chamber. A heating channel outlet is provided on the outer shell. The heating channel communicates with the interior of the high-temperature chamber through the heat outlet and with the interior of the low-temperature chamber through the first and second heat inlets. The first temperature regulating component and the second temperature regulating component are used to control the amount of heat entering the first heat inlet and the second heat inlet, thereby regulating the temperature inside the low-temperature chamber.

[0007] Furthermore, the first temperature regulating component includes a first fixed cover fixedly disposed on the side of the low-temperature chamber facing the spacer layer, and a first movable cover slidably disposed on the side of the low-temperature chamber facing the spacer layer.

[0008] Furthermore, the first fixing cover includes a first fixing cover body fixedly installed in the heat channel, and a plurality of first heat dissipation holes equally spaced on the first fixing cover body.

[0009] Furthermore, the first movable cover includes a first movable cover body located on the side of the first fixed cover facing the high-temperature unit, a plurality of first seals disposed on one side of the first movable cover body, a plurality of second seals disposed on the other side of the first movable cover body, a plurality of first sliding holes disposed on the side of the low-temperature chamber facing the first movable cover body, a plurality of mounting parts for mounting the first movable cover body, and a movable handle for moving the first movable cover body.

[0010] Furthermore, the main body of the first movable cover is arranged in an "L" shape.

[0011] Furthermore, the first heat inlet and the first heat dissipation hole are misaligned.

[0012] Furthermore, the second temperature regulating component includes a second fixed cover fixedly disposed on the housing, and a second movable cover slidably mounted on the second fixed cover.

[0013] Furthermore, the second fixing cover includes a second fixing cover body fixedly installed on the top of the outer shell, a plurality of second heat dissipation holes spaced apart on the second fixing cover body, and two second sliding holes symmetrically arranged on both sides of the second fixing cover body.

[0014] Furthermore, the second movable cover includes a second movable cover body slidably connected to the second fixed cover body, a plurality of third seals corresponding to the second heat dissipation holes, and two sliding handles symmetrically arranged on both sides of the second movable cover body.

[0015] Furthermore, the length of the second movable cover is shorter than the length of the second fixed cover body.

[0016] Compared with existing technologies, the heat-recycling oven with an adjustable temperature heating channel structure provided by this utility model adds a low-temperature unit to one side of the high-temperature unit, and sets up a heating channel to transfer part of the heat from the high-temperature unit to the low-temperature unit for secondary utilization. Specifically, a first heating inlet and a second heating inlet are provided on the low-temperature chamber of the low-temperature unit. The heating channel communicates with the interior of the low-temperature chamber through the first heating inlet and the second heating inlet. Thus, part of the heat from the high-temperature unit is transferred to the low-temperature chamber for secondary utilization. At the same time, a first temperature regulating component and a second temperature regulating component are also provided to control the heat entering the low-temperature chamber through the first heating inlet and the second heating inlet, thereby regulating the baking temperature of the low-temperature unit. When the low-temperature unit does not need to be heated for baking, the heating channel can also be directly connected to the outside for heat dissipation. Therefore, the heat-recycling oven with an adjustable temperature heating channel structure not only improves the oven's heat utilization rate, but also improves the oven's heat dissipation effect.

[0024] The specific embodiments of this utility model will be described in further detail below. It should be understood that the description of this utility model herein is not intended to limit the scope of protection of this utility model.

[0025] like Figures 1 to 7 The diagram shown is a structural schematic of a reusable oven with an adjustable temperature heating channel structure provided by this utility model. The reusable oven includes a storage unit 10, a high-temperature unit 20 disposed on one side of the storage unit 10, and a low-temperature unit 30 fixedly disposed on one side of the high-temperature unit 20. It is conceivable that the reusable oven with an adjustable temperature heating channel structure should also include other related functional components, such as control components, assembly components, and electrical connection components, all of which are prior art known to those skilled in the art and will not be described in detail here.

[0026] The storage unit 10 supports the high-temperature unit 20 and the low-temperature unit 30, and can also be used to store items. Multiple casters can be provided at the bottom of the storage unit 30 to facilitate moving the oven. The storage unit 10 itself is existing technology and will not be described in detail here.

[0027] The high-temperature unit 20 includes a high-temperature box 21 disposed on the storage unit 10, an electric heating plate 22 fixedly disposed on the top of the high-temperature box 21, and at least one heat outlet 23 disposed on the top side of the high-temperature box 21.

[0028] The high-temperature chamber 21 is used to support the heating plate 22, as well as the baking tray, grill, heat dissipation components, and other related components, and provides a sealed environment for baking objects with high temperature requirements. The high-temperature chamber 21 itself is existing technology and will not be described in detail here.

[0029] The heating plate 22 is fixedly installed on the top of the high-temperature chamber 21. After being powered on, the heating plate 22 can release a large amount of heat to bake the items inside the high-temperature chamber 21. The specifications of the heating plate 22 can be selected according to the baking temperature requirements of the high-temperature unit 20 to ensure that it can heat the temperature inside the high-temperature chamber 21 to the required baking temperature. The heating plate 22 itself is existing technology and will not be described in detail here.

[0030] In this invention, a heat outlet 23 is provided on both sides of the heating plate 22 and on the side opposite to the door opening side of the high-temperature unit 20. The heat outlet 23 connects the high-temperature unit 20 and the low-temperature unit 30, allowing the residual heat from the high-temperature unit 20 to be transferred to the low-temperature unit 30, thereby providing a heating temperature for the low-temperature unit 30. This will be further described in detail below with reference to the low-temperature unit 30.

[0031] The low-temperature unit 30 includes a low-temperature chamber 31 fixedly mounted on the high-temperature unit 20, an outer shell 32 disposed outside the low-temperature chamber 31, a spacer layer 33 located between the low-temperature chamber 31 and the outer shell 32, a heat channel 34 located between the spacer layer 33 and the low-temperature chamber 31, a first temperature regulating component 35 disposed within the heat channel 34, and a second temperature regulating component 36 disposed on the outer shell 32.

[0032] The low-temperature chamber 31 is also equipped with grill racks, baking trays, and other related functional components for baking items that require lower temperatures, such as vegetables and potatoes. A first heat inlet 311 is located on the side of the low-temperature chamber 31 opposite to its door. A second heat inlet 312 is located on the top of the low-temperature chamber 31. While the high-temperature unit 20 is operating, some of its heat enters the heat channel 34 through the heat outlet 23. Then, guided by the heat channel 34 and adjusted by the first temperature regulating component 35 and the second regulating component 36, the heat enters the low-temperature chamber 31 through the first heat inlet 311 and the second heat inlet 312 to provide baking temperature for the low-temperature unit 30. The two side plates of the low-temperature chamber 31 connected to the spacer layer 33 extend towards the side of the low-temperature chamber 31 facing the second temperature regulating component 36, the side of the high-temperature unit 20, and the back side (i.e., the side opposite to the door opening side of the low-temperature chamber 31) according to the width of the heat channel 34, and are connected to the spacer layer 33 to form the heat channel 34. This will be further described in detail below with reference to the spacer layer 33.

[0033] The outer shell 32 is spaced apart from the low-temperature chamber 31 and the spacer layer 33 on the outside. It is used to assemble the low-temperature unit 30 and the high-temperature unit 20, and also serves to insulate and keep the heat source, preventing burns to personnel. The outer shell 32 itself is existing technology and will not be described in detail here. A heat duct outlet 321 for hot gas output is provided on the outer shell 32.

[0034] The spacer layer 33 is spaced apart from the top and back of the low-temperature chamber 31 and fixedly connected to the left and right side plates of the low-temperature chamber 31, thereby forming the heat channel 34 with the low-temperature chamber 31. The side of the spacer layer 33 near the heat channel outlet 321 is fixed to the outer shell 32 along the edge of the heat channel outlet 321. At the same time, a partition is provided on the side of the heat channel outlet 321 opposite to the spacer layer 33 to seal the gap between the low-temperature chamber 31 and the outer shell 32, thereby isolating the space between the heat channel 34 and the outer shell 32 and the low-temperature chamber 31 from each other, preventing hot air from rushing into the gap between the outer shell 32 and the low-temperature chamber 31, which would not only cause insufficient baking temperature inside the low-temperature chamber 31, but also cause the outer shell 32 to overheat and lose its original heat insulation effect.

[0035] The heat channel 34 communicates with the interior of the low-temperature chamber 31 through the first heat inlet 311 and the second heat inlet 312, and is connected to the outside through the heat channel outlet 321. When the oven is working, some of the heat emitted by the heating plate 21 can enter the heat channel 34, and under the action of the first temperature regulating component 35 and the second temperature regulating component 36, it can be reused inside the low-temperature chamber 31 through the first heat inlet 311 or the second heat inlet 312, or it can be discharged through the heat channel outlet 321 for heat dissipation.

[0036] like Figure 6 and Figure 7 As shown, the first temperature regulating component 35 includes a first fixed cover 351 fixedly disposed on the side of the low temperature chamber 31 facing the spacer layer 33, and a first movable cover 352 slidably disposed on the side of the low temperature chamber 31 facing the spacer layer 33.

[0037] The first fixed cover 351 includes a first fixed cover body 3511 fixedly installed within the heat duct 34, and a plurality of first heat dissipation holes 3512 equally spaced on the first fixed cover body 3511. The first fixed cover body 3511 is configured according to the dimensions of the flue 34 and is located on the side of the first heat inlet 311 facing the top of the low-temperature chamber 31. One side of the first fixed cover body 3511 is fixedly connected to the low-temperature chamber 31, and the other side is fixedly connected to the spacer layer 33. The first heat dissipation holes 3512 are equally spaced along the length of the first fixed cover body 3511. The extending directions of the first heat inlet 311 and the extending directions of the first heat dissipation holes 3512 are staggered, so that when the first movable cover 352 blocks the first heat inlet 311, the first heat dissipation holes 3512 are opened, and when the first heat inlet 311 is open, the first heat dissipation holes 3512 are blocked.

[0038] The first movable cover 352 includes a first movable cover body 3521 located on the side of the first fixed cover 351 facing the high temperature unit 20, a plurality of first seals 3522 disposed on one side of the first movable cover body 3521, a plurality of second seals 3523 disposed on the other side of the first movable cover body 3521, a plurality of first sliding holes 3524 disposed on the side of the low temperature chamber 31 facing the first movable cover body 3521, a plurality of mounting parts 3525 for mounting the first movable cover body 3521, and a moving handle 3526 for moving the first movable cover body 3521.

[0039] The first movable cover body 3521 is L-shaped. One side of the first movable cover body 3521 is slidably mounted on one side of the first heat inlet 311 of the low temperature chamber 31 via the mounting member 3525, and the other side abuts against the first fixed cover body 3511.

[0040] The first seal 3522 and the second seal 3523 are respectively disposed on both sides of the first movable cover body 3521, corresponding to the first heat inlet 311 and the first heat dissipation hole 3512, and the size and spacing of the first seal 3522 and the second seal 3523 are corresponding to the first heat inlet 311 and the first heat dissipation hole 3512. The first seal 3522 and the second seal 3523 are used to close the first heat inlet 311 and the first heat dissipation hole 3512, respectively. The placement of the first seal 3522 and the second seal 3523 should be based on achieving the following function: when the first seal 3522 blocks the first heat dissipation hole 3512, the second seal 3523 opens the first heat inlet 311; and when the first seal 3522 opens the first heat dissipation hole 3512, the second seal 3523 blocks the first heat inlet 311.

[0041] Multiple first sliding holes 3524 are respectively disposed around the perimeter and center of the first heat inlet 311. The first sliding holes 3524 can be oblong to facilitate the sliding of the mounting component 3525 within the first sliding holes 3524. The length of the first sliding holes 3524 is set according to the required sliding length of the first movable cover body 3521.

[0042] The mounting component 3525 is matched with the first sliding hole 3524, and one end of it passes through the first sliding hole 3524 and is fixedly connected to the first movable cover body 3521, thereby sliding the first movable cover body 3521 on the low temperature chamber 31.

[0043] One end of the movable handle 3526 is fixedly connected to the first movable cover body 3521, and the other end extends a certain length through the first sliding hole 3524 toward the opening side of the low-temperature chamber 31 for easy handling. Before using the oven, the movable handle 3526 can be moved from the opening side of the low-temperature chamber 31 according to the temperature requirements inside the low-temperature chamber 10, so that the first heat inlet 311 is fully open, partially open, or closed, thereby controlling the heat entering the low-temperature chamber 10, so that the temperature inside the low-temperature chamber 10 is within a certain range according to the baking requirements. Specifically, the first heat inlet 311 and the first heat dissipation hole 3512 are staggered, so that when the first heat inlet 311 is open, the first heat dissipation hole 3512 is closed, and vice versa. (Refer to...) Figure 6 As shown, when the moving handle 3526 is located at the leftmost position of the first sliding hole 3524, the first seal 3522 is completely aligned with the first heat inlet 311, and the first heat inlet 311 is in a completely closed state. Furthermore, the second seal 3523 is completely offset from the first heat dissipation hole 3512, and the first heat dissipation hole 3512 is in a completely open state. At this time, the heat transferred from the high-temperature unit 20 is released through the first heat dissipation hole 3512 and continues to be dissipated along the heat channel 34 to the heat channel outlet 321. When the low-temperature chamber 31 is required for baking, the moving handle 3526 can be moved to the right of the first sliding hole 3524 according to the required baking temperature, thereby adjusting the alignment of the first seal 3522 with the first heat inlet 311, so that the first heat inlet 311 is in a partially open or fully open state. When the first heat inlet 311 is partially open, a portion of the heat transferred from the high-temperature unit 20 enters the low-temperature chamber 31 through the first heat inlet 311, while a portion is discharged through the first heat dissipation hole 3512. When the first heat inlet 311 is fully open, the first heat dissipation hole 3512 is fully closed, and all the heat transferred from the high-temperature unit 20 enters the low-temperature chamber 10 through the first heat inlet 311.

[0044] Since the movable handle 3526 is located inside the low-temperature chamber 10, the oven door of the low-temperature chamber 10 needs to be opened for adjustment. However, during baking, the stability of the low-temperature oven 20 often needs to be adjusted multiple times based on the doneness of the baked goods and the temperature changes within the high-temperature unit 20. At this time, because the low-temperature chamber 10 contains items to bake and the temperature is high, it is inconvenient to open the door to adjust the position of the movable handle 3526, and heat loss is likely to occur during the opening and closing of the oven door. Therefore, a second temperature adjustment component 36 is further added at the heat outlet 321 to perform secondary temperature adjustments within the low-temperature chamber 10.

[0045] The second temperature regulating component 36 includes a second fixed cover 361 fixedly mounted on the housing 32, and a second movable cover 362 slidably mounted on the second fixed cover 361.

[0046] The second fixed cover 361 includes a second fixed cover body 3611 fixedly mounted on the top of the outer casing 32, a plurality of second heat dissipation holes 3612 spaced apart on the second fixed cover body 3611, and at least two second sliding holes 3613 symmetrically arranged on both sides of the second fixed cover body 3611. The size of the second fixed cover body 3611 matches the size of the heat channel outlet 321, is correspondingly arranged with the heat channel outlet 321, and is fixedly mounted on the outer casing 32. The plurality of second heat dissipation holes 3612 are equally spaced on the top of the second fixed cover body 3611, and are used to dissipate heat output through the heat channel 34. The second sliding holes 3613 are symmetrically arranged on both sides of the second fixed cover body 3611 along the length direction of the second fixed cover body 3611. The second sliding holes 3613 can be oblong holes, which are used to set the second movable cover 362. The length of the second sliding holes 3613 can be set according to the left and right movement distance of the second movable cover 362.

[0047] The second movable cover 362 includes a second movable cover body 3621 slidably connected to the second fixed cover body 3611, a plurality of third seals 3622 corresponding to the second heat dissipation holes 3612, and at least two sliding handles 3623 symmetrically arranged on both sides of the second movable cover body 3621. The second movable cover body 3621 is matched with the second fixed cover body 3611, specifically, the second movable cover body 3621 can be accommodated within the second fixed cover body 3611 and fits snugly against the inner contour of the second fixed cover body 3611. The length of the second movable cover 3612 can be shorter than that of the second fixed cover body 3611, specifically, the second movable cover body 3621 can be moved left or right within the second fixed cover body 3611 by the width of one second heat dissipation hole 3612, for aesthetic purposes. The plurality of third seals 3622 are corresponding to the second heat dissipation holes 3612 and are used to seal the second heat dissipation holes 3612. The sliding handle 3623 is inserted into the second sliding hole 3613, thereby fixing the second movable cover body 3621 inside the second fixed cover body 3611. One end of the sliding handle 3623 can be fixedly connected to the second movable cover body 3621 by means of screw connection or other connection methods, which facilitates disassembly.

[0048] by Figure 5 For reference, when the sliding handle 3623 is located at the rightmost side of the second sliding hole 3613, the third seal 3622 is completely offset from the second heat dissipation hole 3612. At this time, the second heat dissipation hole 3612 is fully open, and the heat transmitted through the heat channel 34 can be dissipated to the outside through the second heat dissipation hole 3612. Since hot gas will automatically prioritize rising, hot gas will not enter the low-temperature chamber 21 from the second heat inlet 312 at this time, so it will not have a significant impact on the temperature of the low-temperature unit 30. When it is necessary to increase the temperature inside the low-temperature chamber 31, or when it is not necessary to dissipate heat to the outside, the sliding handle 3623 can be slid to the left, so that the third seal 3622 partially or completely overlaps with the second heat dissipation hole 3612, thereby adjusting the heat dissipated by the second heat dissipation hole 3612. As a result, the heat that cannot be dissipated will enter the low-temperature chamber 31 from the second heat inlet 312, thereby increasing the temperature inside the low-temperature chamber 31. Meanwhile, by adjusting the overlap between the third seal 3622 and the second heat dissipation hole 3611, the temperature inside the low-temperature chamber 31 can be controlled.

[0049] Compared with the prior art, the heat-recycling oven with an adjustable temperature heating channel structure provided by this utility model adds a low-temperature unit 30 to one side of the high-temperature unit 20, and sets up a heating channel 34 to transfer part of the heat from the high-temperature unit 20 into the low-temperature unit 30 for secondary use. Specifically, a first heating inlet 311 and a second heating inlet 312 are provided on the low-temperature chamber 31 of the low-temperature unit 30. The heating channel 34 communicates with the interior of the low-temperature chamber 31 through the first heating inlet 311 and the second heating inlet 312. Thus, part of the heat from the high-temperature unit 30 is transferred into the low-temperature chamber 31 for secondary use. At the same time, a first temperature regulating component 35 and a second temperature regulating component 36 are also provided to control the heat entering the low-temperature chamber 31 through the first heating inlet 311 and the second heating inlet 312, thereby allowing the baking temperature of the low-temperature unit 20 to be regulated. When the low-temperature unit 30 does not require heating for baking, the heat channel 34 can also be directly connected to the outside for heat dissipation. Therefore, the oven with adjustable temperature heat channel structure that can reuse heat not only improves the oven's heat utilization rate, but also improves the oven's heat dissipation effect.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
