Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to cooking equipment. Background Technology

[0002] In the field of modern kitchen appliances, steam ovens are becoming increasingly widely used. Among them, dehumidification technology is a key function that not only directly affects the taste and quality of cooked food, but also has a significant impact on the comfort of the kitchen environment and the drying efficiency of the appliance. As consumers pursue a high-quality cooking experience and a convenient kitchen life, efficient and intelligent dehumidification technology has become a core element for enhancing the competitiveness of steam ovens in the market, and the market demand for its innovation and optimization continues to rise.

[0003] Currently, the mainstream dehumidification technologies in the steam oven industry mainly include wax motor dehumidification technology and humidity-controlled insert dehumidification technology. Wax motor dehumidification technology is based on the principle of thermodynamic expansion and contraction, controlling the opening of small holes pre-set on the inner cavity of the oven to allow moisture to escape autonomously. Humidity-controlled insert technology uses a specially designed rubber component that creates a gap by pushing open the door to allow moisture to escape. These technologies, after long-term development and application, have to a certain extent met the basic dehumidification needs of steam ovens and have become widely adopted solutions in the industry.

[0004] However, both existing dehumidification technologies still have many limitations. The wax motor dehumidification technology, due to its small dehumidification channel design, suffers from limited moisture flow efficiency. In cooking scenarios requiring rapid removal of large amounts of steam, such as the final stages of high-temperature steaming or rapid baking, it struggles to achieve efficient dehumidification, thus affecting cooking results and drying efficiency. The humidity control insert technology relies on manual addition of the inserts, which is cumbersome and reduces user experience. Furthermore, due to safety concerns, it cannot activate the exhaust system during cooking or promptly remove accumulated steam after cooking. This affects the final quality of the food, may lead to excessive humidity in the kitchen, and could even damage internal components of the steam oven due to residual steam, shortening the equipment's lifespan. Utility Model Content

[0005] Therefore, it is necessary to provide a cooking device that addresses the problems of low dehumidification efficiency and complex operation in existing steam ovens.

[0006] A cooking device includes an inner pot, a guide plate, and a steam exhaust assembly. The inner pot contains a cooking space and includes a top plate defining the cooking space. The top plate has a steam exhaust port communicating with the cooking space. The guide plate is connected to the inner pot and located on the end face of the top plate opposite to the cooking space. The guide plate and the top plate together form a guide channel communicating with the outside. The steam exhaust assembly includes a steam exhaust plate movable between a steam exhaust position and a blocking position sequentially arranged along the axial direction of the steam exhaust port. When the steam exhaust plate is in the blocking position, it is located inside the steam exhaust port and blocks it. When the steam exhaust plate is in the steam exhaust position, it is located outside the steam exhaust port. The cooking space, the steam exhaust port, and the guide channel are sequentially connected.

[0007] In one embodiment, when the vent plate is in the venting position, the vent plate is located inside the cooking space, and the vent plate and the top plate are spaced apart in the axial direction of the vent.

[0008] In one embodiment, when the vent plate is located in the blocked position, the end face of the vent plate facing the cooking space is flush with the end face of the top plate facing the cooking space.

[0009] In one embodiment, the exhaust plate and the top plate have the same thickness.

[0010] In one embodiment, the top plate includes an inner plate, an insulation layer, and an upper mounting plate arranged sequentially along the axial direction of the vent, with the inner plate facing the cooking space.

[0011] In one embodiment, the vent plate includes an inner partition layer located at the end of the vent plate facing the cooking space, the inner partition layer and the inner plate being made of the same material; and / or, the vent plate includes an outer partition layer located at the end of the vent plate away from the cooking space, the outer partition layer and the upper mounting plate being made of the same material; and / or, the vent plate includes a thermal insulation layer located at the middle portion of the vent plate along the axial direction of the vent, the thermal insulation layer and the thermal insulation interlayer being made of the same material.

[0012] In one embodiment, the top plate includes a limiting strip connected to the upper mounting plate and protruding from the end face of the upper mounting plate facing the insulation interlayer. The limiting strip is an annular structure surrounding the vent.

[0013] In one embodiment, the exhaust assembly further includes a drive member connected to the air guide plate, the drive member being tractively connected to the exhaust plate and used to move the exhaust plate between the blocking position and the exhaust position.

[0014] In one embodiment, the air guide plate has a mounting hole located at the exhaust port, the drive member is at least partially located in the mounting hole, and the exhaust assembly further includes a sealing sleeve, which is sleeved on the outer periphery of the drive member and sandwiched between the hole wall of the mounting hole and the drive member.

[0015] In one embodiment, the sealing sleeve includes a sealing portion and a connecting portion connected together. The sealing portion has an annular structure that is sleeved on the outer periphery of the drive member, and the connecting portion protrudes from the outer periphery of the sealing portion and is used to fix the air guide plate.

[0016] The cooking equipment provided in the above solution, by setting an exhaust plate that can move between the exhaust position and the blocking position, controls the connection and disconnection of the exhaust port and the air guide channel. When the exhaust plate is in the exhaust position, the hot steam in the cooking space can enter the air guide channel through the exhaust pipe or the exhaust port, which improves the efficiency of the hot steam in the cooking space being discharged to the outside of the cooking equipment through the air guide channel. Moreover, the exhaust plate is located inside the cooking equipment, and its movement can be used to adjust the exhaust efficiency by controlling the connection and disconnection of the exhaust port and the air guide channel, which facilitates automated control and simplifies operation.

[0034] See Figure 1 , Figure 1A schematic diagram of the structure of a cooking device 100 according to an embodiment of this application is shown. The cooking device 100 provided in this embodiment can be a steam oven, steamer, oven, or other cooking equipment, and is not limited thereto. The cooking device 100 includes an inner liner 110, and a cooking space 111 is provided inside the inner liner 110 for cooking food. The inner liner 110 includes a top plate 112 defining the cooking space 111. It is understood that the inner liner 110 also includes a bottom wall and side walls defining the cooking space 111, and the top plate 112 is only used to define the top of the cooking space 111. Figure 1 As shown, the top plate 112 has an exhaust port 1121 that communicates with the cooking space 111. In this embodiment, the exhaust port 1121 passes through the cooking space 111 so that the cooking space 111, the exhaust port 1121 and the air guide channel 121 described below are connected.

[0035] Combination Figure 2 As shown, Figure 2 A cross-sectional schematic diagram of a cooking device 100 according to an embodiment of this application is shown. The cooking device 100 also includes a guide vane 120 and a steam exhaust assembly 130. The guide vane 120 is connected to the inner liner 110 and is located on the end face of the top plate 112 opposite to the cooking space 111. The guide vane 120 and the top plate 112 together form a guide channel 121 communicating with the outside.

[0036] Combination Figure 3 As shown, in this embodiment, the cooking device 100 also includes a steam exhaust pipe 140, the two ends of which are connected to the air guide channel 121 and the cooking space 111, respectively. In some embodiments, the side wall of the inner liner 110 is provided with an opening that communicates with the steam exhaust pipe 140, but this is not a limitation.

[0037] Combination Figure 4 and Figure 5 As shown, the exhaust assembly 130 includes components that can be sequentially arranged along the axial direction of the exhaust port 1121, such as... Figure 1 and Figure 2 The exhaust location shown and as Figure 4 and Figure 5 The exhaust plate 131 moves between the shown blocking positions and is used to control the connection and disconnection of the exhaust port 1121 and the air guide channel 121.

[0038] like Figure 4 and Figure 5 As shown, when the exhaust plate 131 is in the blocked position, the exhaust plate 131 is located inside the exhaust port 1121 and blocks the exhaust port 1121. At this time, the cooking space 111 cannot connect to the air duct 121 through the exhaust port 1121, as... Figure 5 As shown, hot steam in the cooking space 111 can enter the air duct 121 through the exhaust pipe 140.

[0039] like Figure 1 and Figure 2 As shown, when the exhaust plate 131 is in the exhaust position, the exhaust plate 131 is located outside the exhaust port 1121, and the cooking space 111, the exhaust port 1121, and the air guide channel 121 are connected in sequence, as follows. Figure 2 As shown, the hot steam in the cooking space 111 can enter the air guide channel 121 through the exhaust pipe 140 or through the exhaust port 1121, which improves the efficiency of the hot steam in the cooking space 111 being discharged to the outside of the cooking equipment 100 through the air guide channel 121. Moreover, the exhaust plate 131 is located inside the cooking equipment 100, and its movement can be used to adjust the exhaust efficiency by controlling the connection and disconnection of the exhaust port 1121 and the air guide channel 121, which facilitates automated control and simplifies operation.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, when the vent plate 131 is in the venting position, the vent plate 131 is located inside the cooking space 111, and the vent plate 131 and the top plate 112 are spaced apart axially in the vent port 1121, as shown. Figure 2 As shown, the axial spacing between the two at the exhaust port 1121 forms the flow space for hot steam to flow from the cooking space 111 to the exhaust port 1121 and the air guide channel 121.

[0041] It is understood that the size of the axial spacing between the exhaust plate 131 and the top plate 112 at the exhaust port 1121 affects the rate at which hot steam from the cooking space 111 flows into the air guide channel 121. In some embodiments, the exhaust plate 131 can switch between a blocking position and an exhaust position to achieve the opening and closing of the cooking space 111 and the air guide channel 121. In other embodiments, the exhaust plate 131 can remain at any position between the blocking position and the exhaust position, thereby adjusting the rate at which hot steam from the cooking space 111 flows into the air guide channel 121.

[0042] like Figure 4 and Figure 5 As shown, in one embodiment, when the vent plate 131 is in the blocked position, the end face of the vent plate 131 facing the cooking space 111 is flush with the end face of the top plate 112 facing the cooking space 111. It can serve as part of defining the cooking space 111 and visually integrate into the top plate 112, making the cooking device 100 more visually integrated.

[0043] like Figure 5As shown, in one embodiment, the vent plate 131 and the top plate 112 have the same thickness. When the vent plate 131 is in the blocked position, the vent plate 131 can completely fill the vent 1121 in the axial direction, so that the heat in the cooking space 111 is more uniform and temperature changes are avoided due to uneven thickness in some areas.

[0044] like Figure 2 and Figure 5 As shown, in one embodiment, the top plate 112 includes an inner plate 1122, a heat insulation interlayer 1123 and an upper mounting plate 1124 arranged sequentially along the axial direction of the exhaust port 1121. The heat insulation interlayer 1123 is sandwiched between the inner plate 1122 and the upper mounting plate 1124. The inner plate 1122 is positioned facing the cooking space 111. The upper mounting plate 1124 and the air guide plate 120 together enclose and form an air guide channel 121.

[0045] like Figures 6 to 8 As shown, in one embodiment, the vent plate 131 includes an inner partition 1311 located at the end of the vent plate 131 facing the cooking space 111. The inner partition 1311 and the inner plate 1122 are made of the same material. Both the inner partition 1311 and the inner plate 1122 are made of metal and are used to isolate the cooking space 111 from the insulation layer 1313 or insulation interlayer 1123 described below, thereby preventing steam in the cooking space 111 from escaping into the insulation layer 1313 or insulation interlayer 1123 during cooking.

[0046] In one embodiment, the vent plate 131 includes an outer partition 1312 located at the end of the vent plate 131 facing away from the cooking space 111. The outer partition 1312 and the upper mounting plate 1124 are made of the same material. Both the outer partition and the upper mounting plate 1124 are made of metal and are used to isolate the following insulation layer 1313 or insulation interlayer 1123 and air guide plate 120 to maintain the appearance of the cooking equipment 100.

[0047] In one embodiment, the exhaust plate 131 includes a thermal insulation layer 1313, which is located in the middle of the exhaust plate 131 along the axial direction of the exhaust port 1121, sandwiched between the outer partition layer 1312 and the inner partition layer 1311. The thermal insulation layer 1313 and the thermal insulation interlayer 1123 are made of the same material. Both the thermal insulation layer 1313 and the thermal insulation surface layer are used to slow down the heat loss within the cooking space 111 during the cooking process, thereby improving the heating efficiency within the cooking space 111. In this embodiment, both the thermal insulation layer 1313 and the thermal insulation interlayer 1123 are thermal insulation cotton. The thermal insulation cotton of the thermal insulation layer 1313 is treated with a sealing measure, such as wrapping it with aluminum foil, to prevent the cotton from escaping.

[0048] Combination Figures 7 to 9As shown, in one embodiment, the top plate 112 includes a limiting strip 1125, which is connected to the upper mounting plate 1124 and protrudes from the end face of the upper mounting plate 1124 facing the insulation interlayer 1123. The limiting strip 1125 is an annular structure surrounding the vent 1121, so as to utilize the flexibility of the insulation interlayer 1123 itself to squeeze and compress the insulation cotton in the insulation interlayer 1123 to create a closed environment, so as to ensure that the steam can be discharged according to the preset route after the vent 1121 is opened and closed.

[0049] like Figures 6 to 8 As shown, in one embodiment, the exhaust assembly 130 further includes a drive member 132 connected to the air guide plate 120. The drive member 132 is connected to the exhaust plate 131 and is used to drive the exhaust plate 131 to move between the blocking position and the exhaust position, providing power for the movement of the exhaust plate 131.

[0050] like Figures 6 to 8 As shown, in one embodiment, the air guide plate 120 has a mounting hole 122 located at the exhaust port 1121. The drive member 132 is at least partially located in the mounting hole 122. The exhaust assembly 130 also includes a sealing sleeve 133, which is sleeved on the outer periphery of the drive member 132 and sandwiched between the hole wall of the mounting hole 122 and the drive member 132, thereby sealing the gap between the hole wall of the mounting hole 122 and the drive member 132 to prevent hot steam in the air guide channel 121 from overflowing from the gap between them.

[0051] like Figures 6 to 8 As shown, in one embodiment, the sealing sleeve 133 includes a sealing part 1331 and a connecting part 1332 connected to each other. The sealing part 1331 has an annular structure that is sleeved on the outer periphery of the driving member 132. The connecting part 1332 protrudes from the outer periphery of the sealing part 1331 and is used to fix and connect the air guide plate 120 to realize the installation of the exhaust assembly 130.

[0052] like Figures 6 to 8 As shown, in one embodiment, the exhaust assembly 130 further includes a transmission rod 134 connected between the drive member 132 and the exhaust plate 131 to drive the exhaust plate 131 to move between a blocking position and an exhaust position. Exemplarily, the drive member 132 and the transmission rod 134 can be pneumatic or electric telescopic rods, etc., and are not limited thereto.

[0053] The cooking equipment 100 provided in the above solution, when the exhaust plate 131 is in such a state Figure 1 and Figure 2When the exhaust position is as shown, hot steam in the cooking space 111 can enter the air guide channel 121 through the exhaust pipe 140, and can also directly enter the air guide channel 121 through the exhaust port 1121, directly connecting with the outside. The hot steam in the air guide channel 121 is discharged to the outside through the fan connected to the air guide plate 120 and its own flow. When the exhaust plate 131 is in the position shown, Figure 4 and Figure 5 When the blockage position is shown, the hot steam in the cooking space 111 can enter the air guide channel 121 through the exhaust pipe 140. In practical applications, taking the cooking equipment 100 as a steam oven as an example, when drying fruits and vegetables, the exhaust port 1121 is opened, and the generated humid air is discharged to the outside through the exhaust port 1121, greatly improving the dehumidification efficiency; when steaming food is finished, the exhaust port 1121 is opened, and the internal steam is discharged to the outside through the exhaust port 1121, achieving the effect of no steam when the door is opened, reducing the safety hazard of steam rushing out when the door is opened.

[0054] The cooking equipment 100 provided in the above solution, by setting an exhaust plate 131 that can move between the exhaust position and the blockage position, controls the connection and disconnection of the exhaust port 1121 and the air guide channel 121. When the exhaust plate 131 is in the exhaust position, the hot steam in the cooking space 111 can enter the air guide channel 121 through the exhaust pipe 140 or through the exhaust port 1121. This improves the efficiency of the hot steam in the cooking space 111 being discharged to the outside of the cooking equipment 100 through the air guide channel 121. Moreover, since the exhaust plate 131 is located inside the cooking equipment 100, it only needs to be moved to control the connection and disconnection of the exhaust port 1121 and the air guide channel 121, thereby adjusting the exhaust efficiency, facilitating automated control and simplifying operation.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
