Description

Technical Field

[0001] The present invention relates to the technical field of cooking equipment, and in particular provides a cooking equipment. Background Art

[0002] Cooking equipment such as ovens and steam ovens are essential kitchen appliances for modern families. Taking steam ovens as an example, the existing steam ovens on the market have heating modes such as upper heating tubes, bottom heating tubes, and back heating tubes. Different heating modes are achieved by running different heating tube combinations. Since the heating tubes are fixedly installed, the shape of the heating tubes cannot be too complicated due to the processing technology, and there are often problems such as uneven heating of ingredients, uneven baking color, partial burnt, and partial undercooked.

[0003] In order to heat the ingredients in the oven cavity evenly and bake them with uniform color, some ovens have added a hot air device on the back to promote the circulation of hot air. The operation of the motor and fan in the hot air device promotes the circulation of hot air in the cooking cavity, which is beneficial to keep the color of the ingredients even. However, the effect is limited. Therefore, some manufacturers have begun to study adding an additional hot air device on the top of the cooking cavity.

[0004] As an improvement, the patent document with publication number CN214760664U provides a solution for transmitting the back power to the top through a transmission mechanism, so as to utilize the back motor to synchronously drive the back hot air device and the top hot air device. However, the transmission mechanism in this solution has a complex structure and requires a large installation space, which results in a significant increase in the cost of the existing double hot air steam oven compared to the single hot air steam oven, and the efficiency of generating hot air is low.

[0005] Accordingly, the art needs a new cooking device to solve the above problems. Summary of the invention

[0072] Example 1

[0073] Combine the following Figures 1 to 6 The structure of the steam oven provided in Example 1 of the present invention is described.

[0074] like Figure 1 As shown in , the steam oven provided by the embodiment of the present invention includes a box body and a door body (not shown), and the door body is pivotally connected to the box body. The box body includes an outer shell 1 and an inner tank assembly 2, a heat dissipation assembly 3, etc. arranged in the outer shell 1. The outer shell 1 is composed of an outer plate 11, an outer bottom plate 12, an inner top plate 13, an outer top plate (not shown), an outer back plate 14, a front panel 15, etc., wherein the outer plate 11, the outer bottom plate 12, the inner top plate 13 and the outer back plate 14 are assembled to construct an installation cavity for accommodating the inner tank assembly 2, and the inner tank assembly 2 is installed in the installation cavity, the heat dissipation assembly 3 is installed above the inner top plate 13, and a knob 151 is provided on the front panel 15.

[0075] The inner tank assembly 2 in the embodiment of the present invention includes an inner tank body 21 and a hot air assembly connected to the inner tank body 21 , a hanger 24 , an evaporation plate heating tube 25 , and the like.

[0076] The hot air assembly in this embodiment includes a first hot air unit 22 and a second hot air unit 23 . The first hot air unit 22 is located at the back of the inner liner assembly 2 , and the second hot air unit 23 is located at the top of the inner liner assembly 2 .

[0077] Alternatively, the first hot air unit may also be arranged on the left and right sides of the inner tank body or on one of the two sides. In addition, it may also be arranged on the back and the left and right sides or on one of the two sides.

[0078] like Figures 1 to 4 As shown in , the first hot air unit 22 includes a first fan cover 221, a first electric heater 222, a first fan 223, etc. Specifically, as Figure 2 and Figure 4 As shown, the first fan cover 221 is connected to the inner side of the inner liner back plate 211, and together with the inner liner back plate 211, a first hot air cavity 227 is constructed, and the first electric heater 222 and the first fan 223 are placed in the first hot air cavity 227. Figure 1 and Figure 2As shown in the figure, a plurality of ventilation holes are arranged on the first fan cover 221, the ventilation holes located in the middle constitute the air inlet 2211 of the first hot air cavity 227, and the air in the cooking cavity can enter the first hot air cavity 227 through the ventilation holes of the air inlet 2211, and the ventilation holes located on the periphery of the air inlet 2211 constitute the air outlet 2212 of the first hot air cavity 227, and the hot air in the first hot air cavity 227 can enter the cooking cavity through the air outlet 2212, so that the hot air circulates between the first hot air cavity 227 and the cooking cavity.

[0079] like Figure 1 As shown in , the first electric heater 222 is wound into a ring structure, so that it can be arranged around the periphery of the first fan 223, which is not only beneficial to improving the heating efficiency, but also beneficial to saving installation space.

[0080] like Figure 1 and Figure 4 As shown in , the first fan 223 is connected to the first motor 226, and the first motor 226 is fixedly connected to the outer side of the inner tank back plate 211 through the first motor bracket 224. In order to prevent the motor from overheating during operation, the first motor 226 is also connected to the first cooling fan 225, and the first cooling fan 225 rotates synchronously with the first fan 223, so that the first motor 226 drives the first cooling fan 225 to rotate during the period of driving the first fan 223 to operate, thereby promoting the heat dissipation of the first motor 226 itself. Figure 4 As shown in , in the installed state, the first motor 226 , the first cooling fan 225 and the first motor bracket 224 are located in the space between the inner tank back plate 211 and the outer back plate 14 .

[0081] The second hot air unit 23 in the embodiment of the present invention includes a second fan cover 231, a second electric heater 232, a second fan 233, a second motor 234 and the like.

[0082] Specifically, Figure 1 , Figure 4 and Figure 5 As shown in FIG. 2 , the second fan cover 231 is connected to the inner side of the inner liner top plate 212 and together with the inner liner top plate 212 forms a second hot air chamber 235, in which the second electric heater 232 and the second fan 233 are placed. Figure 1 and Figure 5As shown in the figure, a plurality of ventilation holes are provided on the second fan cover 231, and the plurality of ventilation holes are arranged in a circular array to form an air inlet and outlet, wherein some ventilation holes close to the center of the array constitute an air inlet 2311, and the air in the cooking cavity can enter the second hot air cavity 235 through the ventilation holes of the air inlet 2311, and the ventilation holes located on the periphery of the air inlet 2311 and away from the center of the array constitute an air outlet 2312, and the hot air in the second hot air cavity 235 can enter the cooking cavity through the air outlet 2312, thereby allowing the hot air to circulate between the second hot air cavity 235 and the cooking cavity.

[0083] like Figure 1 As shown in the figure, in the present embodiment, a second fan 233 is provided, and the second fan 233 is provided with a disk surface (not marked), and the disk surface is parallel to the inner tank top plate 212 in the installed state, and the disk surface extends downward to form a first blade portion (not marked), and extends upward to form a second blade portion (not marked), so that the second fan 233 can form air flow on both sides of the disk surface, which is beneficial to increase the hot air volume.

[0084] Alternatively, the second fan 233 may only have the first blade portion. In addition, two or three second fans 233 may be provided. Taking two second fans 233 as an example, they may be arranged at intervals along the length direction of the liner body 21 or at intervals along the width direction.

[0085] like Figure 1 , Figure 3 and Figure 4 As shown in , the heat dissipation assembly 3 includes an air duct cover plate 31 and a heat dissipation fan 32. The air duct cover plate 31 is connected to the inner top plate 13 to form a heat dissipation air duct 33. The heat dissipation fan 32 is connected to the heat dissipation air duct 33 to promote air circulation in the heat dissipation air duct 33. The heat dissipation fan 32 is a cross-flow fan. Figure 4 As shown in, in this embodiment, the top surface portion of the air duct cover 31 is inclined relative to the inner top plate 13 to form a heat dissipation duct 33 with a tapered cross-section, and the second motor 234 is installed in the heat dissipation duct 33. The second motor can be directly connected to the inner top plate 13, and can also be connected to the inner top plate through a second motor bracket. When the second motor 234 is installed inside the heat dissipation duct, its output shaft 2341 only passes through the inner top plate 13. In this way, not only can the air flow of the heat dissipation duct 33 be used to dissipate heat for the second motor without configuring a dedicated heat dissipation fan, but also during the installation process, the output shaft of the second motor 234 passes through the inner top plate 13 and the inner tank top plate 212 in turn and is connected to the second fan 233 located in the second hot air chamber 235. The size of the output shaft 2341 can be shortened, the rigidity of the output shaft of the second motor 234 is improved, and the probability of damage is reduced.

[0086] Alternatively, a transmission mechanism may be further provided, and the transmission mechanism is provided in the second hot air chamber 235 to synchronously transmit the power of the second motor 234 to the second fan to drive the second fan 233 to rotate. The transmission mechanism may be a gear mechanism or a pulley mechanism. In addition, two second motors may be provided, each second motor being used to drive one second fan.

[0087] like Figure 6 As shown in , the second electric heater 232 is arranged on the periphery of the second fan 233. In this embodiment, the second electric heater 232 includes two heating tubes, and the two heating tubes can be independently controlled to open and close to facilitate the adjustment of the power of the second electric heater 232.

[0088] In addition, since the embodiment of the present invention is described by taking a steam oven as an example, the steam oven is also provided with a steam supply system (not shown), including an evaporation tray disposed on the bottom plate of the inner pot (not shown), an evaporation tray heating pipe 25 located below the evaporation tray, and the like. Figure 4 As shown in the figure, a pressure relief port 2121 is formed on the inner pot top plate 212, and the pressure relief port 2121 is connected to a pressure relief channel 26 that runs through the heat dissipation duct 33, which can be selectively opened when running the steaming mode or the baking mode to adjust the pressure in the cooking cavity.

[0089] It can be understood that when the steaming function is not configured, the relevant structure for generating steam is not necessary.

[0090] Based on the above-mentioned steam oven structure, during operation, the steam oven provided by the present invention can form a surrounding three-dimensional circulating hot air through the first hot air unit 22 and the second hot air unit 23, which can ensure that the food is evenly colored during the cooking process. Moreover, due to its simple structure, the structural improvement of the existing steam oven is relatively small, which is conducive to reducing production costs.

[0091] Example 2

[0092] Combine the following Figures 7 to 9 The steam oven provided in Example 2 of the present invention is described.

[0093] like Figures 7 to 9 As shown in , the structure of the steam oven provided in this embodiment is basically the same as that in Embodiment 1, except that the second motor 234 of the steam oven in the embodiment of the present invention is arranged outside the heat dissipation duct 33, as shown in FIG. Figure 8 and Fig. 9As shown in the figure, the output shaft 2341 of the second motor 234 passes through the air duct cover plate 31, the inner top plate 13 and the inner tank top plate 212 in sequence and is connected to the second fan 233. Influenced by the structural design of the heat dissipation air duct 33, in order to improve the connection stability between the second motor 234 and the air duct cover plate 31, in this embodiment, the second motor 234 is connected to the outer top surface of the air duct cover plate 31 through a second motor bracket (not shown). In this way, the maintenance and replacement of the second motor can be facilitated, thereby improving the convenience of installation.

[0094] Since the second motor 234 generates heat during operation, in order to reduce the motor temperature, the second motor 234 in this embodiment is further provided with a second cooling fan 236 on the side facing the air duct cover plate 31. Figure 7 and Fig. 9 As shown in , the second cooling fan 236 and the second fan 233 are both connected to the output shaft 2341 of the second motor 234, so that the second motor 234 drives the second cooling fan 236 to rotate while driving the second fan 233 to operate, thereby promoting the heat dissipation of the second motor 235 itself.

[0095] Alternatively, a transmission mechanism (not shown) may be provided to connect the second motor 234 and the second fan 233, and the transmission mechanism may be provided in the heat dissipation duct 33. During installation, the output shaft 2341 of the second motor 234 only passes through the duct cover plate 31 to connect with the transmission mechanism, or the transmission mechanism may be provided in the second hot air chamber 235. In addition, multiple second fans may be provided.

[0096] from Figure 6 and Figure 8 It can be seen that in the present invention, the second fan 233 can be placed at or near the middle of the second hot air chamber 235, so that the generated hot air can enter the cooking chamber evenly, which is conducive to achieving a uniform temperature field.

[0097] It should be noted that the first motor 226 and the second motor 234 in the embodiment of the present invention may be fixed-speed motors, or dual-speed motors or variable-frequency motors.

[0098] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
