[0030] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] Example 1

[0032] See attached document Figure 1 and 2 As shown, the roasting duck apparatus of this embodiment includes an oven body 1, a heating mechanism for providing heat to the interior of the oven body, and a partition plate 2 vertically arranged inside the oven body. The partition plate 2 divides the oven body 1 into a first chamber 11 and a second chamber 12. A fan 3 is provided in the first chamber 11 for air circulation between the first chamber 11 and the second chamber 12. A rotating rack 4 for hanging ducks to be roasted is provided in the second chamber 12. An openable oven door is provided on the front side of the second chamber 12, and a control panel is provided on the front side of the first chamber 11.

[0033] In this embodiment, the partition plate 2 is made of a perforated, one-piece molded stainless steel plate, and a gap 10 is provided between the bottom of the partition plate 2 and the bottom plate 13 of the furnace body, so that the oil stains accumulated in the first chamber 11 can flow into the second chamber 12, which facilitates the cleaning of oil stains and avoids the accumulation at the bottom of the first chamber, which is difficult to clean.

[0034] For details, see attached. Figure 2As shown, the partition plate 2 has multiple ventilation areas, including a return air grille area 21 at the center, a first air outlet grille area 22 at the lower center, second air outlet through-hole areas 23 on both sides, and a third air outlet through-hole area 24 at the top. The second air outlet through-hole areas 23 on both sides are arranged in an arc shape centered on the return air grille area 21; and the arc-shaped top area of ​​the second air outlet through-hole area 23 extends beyond the top of the return air grille area 21. The second air outlet through-hole area 23 includes at least three rows of through-hole areas arranged from the inside out, and the diameter of the through-hole in the outermost through-hole area is larger than the diameter of the through-hole in the innermost through-hole area. By increasing the through-hole area of ​​the second air outlet through-hole area 23, air flow is facilitated. Combined with the arrangement of the electric heater, the heat from the heating tube can be better absorbed, forming a smoother and faster hot air circulation, and the heat source utilization rate is greatly improved.

[0035] In this embodiment, the first chamber 11 also includes a vertical fixing plate 5. The vertical fixing plate 5 is sealed to the inner wall of the furnace body 1 on all four sides, and is used to divide the first chamber 11 into an inner cavity 111 corresponding to the partition plate 2 and an outer cavity 112 corresponding to the outer side plate 14 of the furnace body. The outer side plate 14 of the furnace body 1 is configured as an openable door for easy installation and maintenance. Furthermore, the outer side plate 14 is provided with heat dissipation holes to facilitate heat dissipation in the outer cavity 112 and extend the service life of the equipment.

[0036] More specifically, the fan 3 is fixed at the center of the vertical fixing plate 5, and the fan blades 31 of the fan 3 are located in the inner cavity 111, corresponding to the return air grille area 21. The motor part 32 of the fan 3 is located in the outer cavity 112. The heating mechanism is an electric heater 6. The control unit 61 of the electric heater 6 is located in the outer cavity 112, and the heating pipe 62 connected to the control unit 61 is sealed through the vertical fixing plate 5 and then located in the inner cavity 111. The heating pipe 62 is arranged around the fan 3 along the arc of the second air outlet area 23 to heat the flowing air formed by the fan 3, thereby regulating the internal temperature of the second chamber 12.

[0037] As attached Figure 2 As shown, in this embodiment, both the return air grille area 21 and the first air outlet grille area 22 employ multiple rows of staggered square grille holes, and the length of each square grille hole is smaller than the diameter of the smallest through hole in the second air outlet through-hole area 23. This facilitates proper filtration of the air entering the first chamber 11 from the second chamber 12, preventing excessive oil contamination from entering the first chamber 11. Furthermore, the return air grille area 21, in conjunction with the larger-diameter second air outlet through-hole area 23, more effectively and quickly promotes the flow of air entering the first chamber 11 through the heating pipe 62 into the second chamber 12, resulting in a large air outlet area, uniform airflow, and rapid temperature adjustment.

[0038] Furthermore, in this embodiment, the bottom plate 13 of the second chamber 12 adopts a shallow funnel-shaped stainless steel structure with a low center and high perimeter. An oil outlet pipe 131 is connected to the center of the bottom plate 13 to quickly discharge the wastewater and waste oil that fall onto the bottom plate 13 to the furnace body, preventing the wastewater and waste oil from evaporating again at high temperatures inside the furnace body and affecting the color and taste of the roast duck.

[0039] Preferably, the roasting duck apparatus in this embodiment further includes an automatic cooling mechanism for cooling the bottom plate 13 of the second chamber 12. The automatic cooling mechanism includes a cooling water tank 15 disposed at the bottom of the second chamber 12 and an automatic control unit for controlling the water temperature in the cooling water tank 15. The bottom of the cooling water tank 15 is provided with an inlet pipe 151 and an outlet pipe 152, respectively equipped with an inlet valve 153 and an outlet valve 154 connected to the automatic control unit. The cooling water tank 15 is provided with a temperature sensor 155 connected to the automatic control unit. Based on the detection data from the temperature sensor 155, the automatic control unit automatically controls the opening and closing of the inlet valve 153 and the outlet valve 154 to achieve constant temperature control of the water in the cooling water tank 15. In specific use, the water temperature in the cooling water tank 15 needs to be controlled to be no higher than 60-90℃.

[0040] Example 2

[0041] See attached document Figure 3 and 4 As shown, this embodiment differs from the previous embodiment in that the heating mechanism in this embodiment uses a microwave generator to roast the duck inside the oven body using the microwave heating principle. The emitting plate 8 of the microwave generator is set on the inner side wall opposite to the partition plate 2' of the second chamber 12, and is used to disperse microwaves into the interior of the second chamber 12. The fan 3 is used to form a heat circulation between the first chamber 11 and the second chamber 12, which helps to improve the heat source utilization rate.

[0042] The specific difference lies in the fact that the partition plate 2' in this embodiment has multiple ventilation zones, including a return air ventilation zone 21' located in the center and a U-shaped outlet air ventilation zone 22' located at the bottom, as shown in the attached figure. Figure 4 As shown. The return air ventilation zone 21' is composed of several ventilation holes arranged in a concentric circle structure, and the U-shaped outlet air ventilation zone 22' is composed of several ventilation holes arranged side-by-side in an arc shape with the same radius. That is, in this embodiment, since there is no heating pipe and there is no need to absorb heat from the heating pipe, the ventilation areas on the partition plate 2' all use uniform ventilation holes, as long as the ventilation requirements are met.

[0043] In order to prevent microwave leakage, a microwave shielding cover is provided on the inner side of the furnace door on the front side of the second chamber 12 in this embodiment, and a microwave shielding ring is provided around the edge of the microwave shielding cover to further prevent microwave leakage.

[0044] Because microwave heating reaches higher temperatures, a high-temperature resistant sealing ring is also provided on the outside of the microwave shielding ring to avoid the problem of existing sealing rings being damaged under high temperatures, resulting in a short service life.

[0045] In this embodiment, microwave heating can greatly shorten the roasting time of roast duck. Compared with the processing time of 1 hour required by electric heating tube, it can save half the time, that is, a batch of roast duck can be roasted in half an hour, and the color is beautiful and the taste is pure.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
