Description

Technical Field

[0001] This utility model relates to a syrup cooking device, and more specifically to a syrup cooking pot that can effectively reduce energy consumption and has a good heating effect. Background Technology

[0002] Currently, most syrup-making devices on the market use electromagnetic heating devices to heat the bottom of the pot. However, this type of syrup-making device consumes a lot of electricity, has low energy efficiency, and the heat is concentrated in the middle of the bottom surface of the pot. This can easily cause some of the syrup at the bottom of the pot's inner cavity to have quality problems due to excessive heat.

[0003] For example, the Chinese patent document CN219270105U, entitled "Electric Heating Mechanism for a Sugar-Cooking Pot," discloses a sugar-cooking pot that includes a pot body, a heating base, and a power supply and heat conduction assembly disposed inside the heating base. The heating base is fixedly connected to the bottom of the pot body, and the interior of the heating base is a heating cavity. The power supply and heat conduction assembly consists of a heating tube, a heating wire, and a power supply wire. The heating tube is sleeved on the surface of the heating wire, and the middle part of the heating tube is bent to make the heating tube have a disc-shaped structure. Several ceramic heat conduction plates are sleeved in the middle of the heating tube, and the ceramic heat conduction plates have a ring-shaped structure. Several heat conduction clips are provided on the top of the heating base, and the ceramic heat conduction plates are inserted into the interior of the heat conduction clips. The heat conduction clips have clamping thread holes in the middle, and bolts are inserted into the clamping thread holes to fix the ceramic heat conduction plates inside the heat conduction clips. The heat conduction clips are tightly attached to each other.

[0004] However, the aforementioned sugar-boiling pot has an unreasonable structure, mainly relying on a small number of ceramic heat-conducting plates to directly transfer heat. The heat transfer efficiency is not high enough, so it still has disadvantages such as low energy utilization, heat concentrated in the middle of the bottom surface of the pot, which easily leads to poor heating effect, some of the syrup at the bottom of the pot cavity has quality problems due to receiving too much heat, and its complex structure makes assembly very troublesome. The ceramic heat-conducting plates are easy to damage and difficult to repair and replace. Utility Model Content

[0005] The purpose of this invention is to provide a syrup cooking pot that effectively improves energy utilization efficiency and provides good heating performance. The technical solution adopted is as follows:

[0006] A syrup cooking pot includes a pot body and a heating mechanism. The pot body has a cooking cavity with an opening at the top, and a heating cavity is formed on the bottom surface of the pot body. The heating mechanism includes a bottom heating unit, which comprises at least two bottom infrared heating elements. All bottom infrared heating elements are respectively installed inside the heating cavity, and each bottom infrared heating element has a first radiating surface facing the cooking cavity. A gap is left between the first radiating surface and the top surface of the heating cavity. The bottom heating unit uses the first radiating surface of the bottom infrared heating elements to emit infrared rays towards the top surface of the heating cavity of the pot body, resulting in good heating effect and uniform heating of the bottom of the cooking cavity (meaning that the heat emitted by each bottom infrared heating element towards the bottom surface of the cooking cavity is more uniform).

[0007] In a preferred embodiment, the bottom infrared heating element includes a first ceramic housing and at least one first heating tube, with all the first heating tubes installed inside the first ceramic housing.

[0008] A more optimized solution involves the first ceramic housing comprising a first rear mounting area and a first front radiation positioning area. The first front radiation positioning area has an outwardly protruding first heating element positioning groove, within which the first heating element is confined. The outer surface of the first front radiation positioning area serves as a first radiation surface. In other words, the outer surface of the first front radiation positioning area becomes uneven due to the outwardly protruding first heating element positioning groove. This not only prevents excessive variations in the thickness of the first ceramic housing at different locations, thus avoiding impacts on heat output, but also effectively increases the area emitting infrared rays, significantly improving heating efficiency.

[0009] A better approach is to maintain a constant ceramic thickness at all locations within the first front-side radiation positioning area. This results in improved performance of the first ceramic shell.

[0010] An even better solution is to have all bottom infrared heating elements evenly distributed, completely covering the bottom surface of the cooking chamber.

[0011] In a preferred embodiment, the heating mechanism further includes a circumferential heating unit disposed on the outer surface of the pot body; the circumferential heating unit includes an annular auxiliary heating tube and / or at least one arc-shaped infrared heating element; the arc-shaped infrared heating element is mounted on a positioning plate on the outer surface of the pot body, with a gap between the arc-shaped infrared heating element and the outer surface of the pot body; the annular auxiliary heating tube is mounted on the outer surface of the pot body.

[0012] A better embodiment is that the arc-shaped infrared heating element includes a second ceramic housing and at least one second heating tube, with all the second heating tubes installed inside the second ceramic housing.

[0013] A better embodiment is that the second ceramic shell consists of a second rear mounting area and a second front radiation positioning area. The second front radiation positioning area has an outwardly protruding second heating tube positioning groove, and the second heating tube is confined within the second heating tube positioning groove. The outer surface of the second front radiation positioning area is a second radiation surface, which faces the outer side of the pot body.

[0014] In a preferred embodiment, the syrup cooking pot further includes a stirring mechanism, which includes a motor, a stirring paddle, and a suspension frame. The suspension frame is installed on the upper opening of the cooking chamber, the motor is installed on the suspension frame, the output shaft of the motor extends vertically downward, and the stirring paddle is installed on the output shaft of the motor and extends into the cooking chamber.

[0015] The advantages of this invention compared to the prior art are that, since multiple bottom infrared heating elements are used to form a bottom heating unit to emit infrared rays for heating, the power of each bottom infrared heating element can be designed as needed, so that each position at the bottom of the cooking chamber can receive appropriate heat; and by using an annular auxiliary heating tube and / or multiple arc-shaped infrared heating elements to form a circumferential heating unit to heat the outer side of the pot, it is possible to further ensure that all parts of the syrup in the cooking chamber are heated evenly, thereby improving product quality and effectively increasing energy utilization.

[0027] like Figure 1-5 As shown, in one embodiment of this application, a syrup cooking pot includes a pot body 1 and a heating mechanism 2. The pot body 1 has a cooking cavity 102 with an opening at the top, and a heating cavity 101 is formed on the bottom surface of the pot body 1. The heating mechanism 2 includes a bottom heating unit 201, which includes multiple bottom infrared heating elements 2011. All bottom infrared heating elements 2011 are respectively installed in the heating cavity 101, and each bottom infrared heating element 2011 has a first radiating surface 20111 facing the cooking cavity 102. A gap is left between the first radiating surface 20111 and the top surface of the heating cavity 101. The bottom heating unit 201 emits infrared rays towards the top surface of the heating cavity 101 of the pot body 1 using the first radiating surface 20111 of each bottom infrared heating element 2011, thereby enabling each bottom infrared heating element 2011 to uniformly heat the corresponding area at the bottom of the cooking cavity 102. Moreover, the bottom heating unit 201 employs multiple bottom infrared heating elements 2011 that operate independently. The power of each bottom infrared heating element 2011 can be designed as needed, so that each position at the bottom of the cooking chamber 102 can receive appropriate heat, which is especially suitable for heating viscous fluids such as syrup.

[0028] like Figure 4 As shown, in one alternative embodiment of this application, the bottom infrared heating element 2011 includes a first ceramic housing 20112 and at least one first heating tube 20113, with all the first heating tubes 20113 installed inside the first ceramic housing 20112.

[0029] like Figure 4As shown, in one optional embodiment of this application, the first ceramic housing 20112 comprises a first rear mounting area 201121 and a first front radiation positioning area 201122. The first front radiation positioning area 201122 has an outwardly protruding first heating element positioning groove 2011221, and the first heating element 20113 is confined within the first heating element positioning groove 2011221. The outer surface of the first front radiation positioning area 201122 is a first radiation surface 20111. In other words, the outer surface of the first front radiation positioning area 201122 becomes uneven due to the outwardly protruding first heating element positioning groove 2011221. This not only prevents excessive changes in the thickness of the first ceramic housing 20112 at various locations, avoiding affecting heat output, but also effectively increases the area emitting infrared rays, significantly improving heating efficiency. Figure 3 As shown, each first heating element 20113 has two electrical connection wires 201131. In this embodiment, there are two first heating elements 20113, so four electrical connection wires 201131 extend from the first rear mounting area 201121 and connect to the control circuit.

[0030] like Figure 1 As shown, in one alternative embodiment of this application, the ceramic thickness at each location of the first front radiation positioning area 201122 remains unchanged. This results in better heat dissipation performance of the first ceramic shell 20112.

[0031] like Figure 2 As shown, in one optional embodiment of this application, the number of bottom infrared heating elements 2011 is five. One of them is disc-shaped, and the other four are arc-shaped. These four elements are distributed sequentially along the circumference of the disc-shaped bottom infrared heating element 2011, so that all the bottom infrared heating elements 2011 are evenly distributed below the bottom surface of the cooking chamber 102, covering the bottom surface of the heating chamber 101. That is, the upward projection of all the bottom infrared heating elements 2011 (not considering the gaps between adjacent bottom infrared heating elements 2011) completely covers the bottom surface of the cooking chamber 102. This design allows the heat emitted by each bottom infrared heating element 2011 towards the bottom surface of the cooking chamber 102 to be more uniform.

[0032] like Figure 6-11As shown, in an optional embodiment of this application, the heating mechanism 2 further includes a circumferential heating unit 202, which is disposed on the outer surface of the pot body 1. The circumferential heating unit 202 includes an annular auxiliary heating tube 2022 and three arc-shaped infrared heating elements 2021 (the three arc-shaped infrared heating elements 2021 are evenly distributed along the circumference of the pot body 1). The outer surface of the pot body 1 has at least one positioning plate 103, and the arc-shaped infrared heating elements 2021 are mounted on the positioning plate 103 on the outer surface of the pot body 1, with a gap between the arc-shaped infrared heating elements 2021 and the outer surface of the pot body 1. The annular auxiliary heating tube 2022 is mounted on the outer surface of the pot body 1.

[0033] like Figure 6 As shown, in one alternative embodiment of this application, the arc-shaped infrared heating element 2021 includes a second ceramic housing 20211 and at least one second heating tube 20212, with all the second heating tubes 20212 installed inside the second ceramic housing 20211.

[0034] like Figure 10 As shown, in one optional embodiment of this application, the second ceramic shell 20211 is composed of a second rear mounting area 202111 and a second front radiation positioning area 202112. The second front radiation positioning area 202112 has an outwardly protruding second heating tube positioning groove 2021121, and the second heating tube 20212 is confined within the second heating tube positioning groove 2021121. The outer surface of the second front radiation positioning area 202112 is a second radiation surface 20213, which faces the outer side of the pot body 1. The outer surface of the second front radiation positioning area 202112 becomes uneven due to the outwardly protruding second heating tube positioning groove 2021121. This not only prevents excessive changes in the thickness of the second ceramic shell 20211 at various locations, avoiding affecting the heat output, but also effectively increases the area for emitting infrared rays, significantly improving heating efficiency.

[0035] like Figure 6 , 10 As shown, in one alternative embodiment of this application, both the second rear mounting area 202111 and the second front radiation positioning area 202112 are recessed inward. This further improves the heating effect.

[0036] like Figure 10 As shown, in one alternative embodiment of this application, the ceramic thickness at each location of the second front radiation positioning area 202112 remains unchanged. This results in better heating performance of the second ceramic housing 20211.

[0037] like Figure 1As shown, in an optional embodiment of this application, the syrup cooking pot further includes a stirring mechanism 3. The stirring mechanism 3 includes a motor 301, a stirring paddle 302, and a suspension frame 303. The suspension frame 303 is installed on the upper opening of the cooking chamber 102. The motor 301 is installed on the suspension frame 303, and the output shaft of the motor 301 extends vertically downward. The stirring paddle 302 is installed on the output shaft of the motor 301 and extends into the cooking chamber 102. In this embodiment, the motor 301 is selected as a servo motor.

[0038] like Figure 1 As shown, in one alternative embodiment of this application, the heating chamber 101 has an opening facing downwards, and a sealing plate 103 is installed on the opening.

[0039] like Figure 1-5 As shown, in one alternative embodiment of this application, the control circuit 4 is connected to the motor 301 and each bottom infrared heating element 2011 respectively, and controls their operation respectively.

[0040] like Figure 6-11 As shown, in one alternative embodiment of this application, the control circuit 4 is connected to the motor 301, each arc-shaped infrared heating element 2021, the annular auxiliary heating tube 2022, and each bottom infrared heating element 2011 respectively, and controls their operation respectively.

[0041] The above embodiments, through improvements to the structure of the syrup cooking pot, employ multiple arc-shaped infrared heating elements 2021 to emit infrared radiation instead of direct contact heating, thus enabling uniform heating of the bottom of the cooking chamber 102. Embodiments equipped with circumferential heating units 202 can heat the sides of the cooking chamber 102 circumferentially, allowing the center of the syrup to receive heat better, further improving the heating effect. The stirring mechanism 3 ensures continuous flow of the syrup, resulting in more even heating. These improved structures work together to effectively improve the quality of the finished product. Furthermore, the shape, size, power, position, and quantity of the arc-shaped infrared heating elements 2021, the annular auxiliary heating tube 2022, and the arc-shaped infrared heating elements 2021 can be adjusted according to production needs to achieve even better heating results. Experiments have shown that this structure of the syrup cooking pot can save more than 30% of energy consumption.

[0042] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, they should all fall within the protection scope of this utility model.
