Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to cooking equipment. Background Art

[0002] As an important steam cooking device in modern kitchens, steamers have been widely used due to their convenience, professionalism and intelligence. As users' requirements for cooking experience continue to increase, the issue of steam emission control during steamer operation has received increasing attention. As a key indicator to measure equipment performance, steamer exhaust volume directly affects safety of use, energy efficiency and user experience. Excessive exhaust volume will not only increase the humidity in the kitchen environment, causing safety hazards such as dampness and mildew of kitchen utensils and accumulation of condensed water, but will also significantly increase the frequency of water tank refilling, affecting the convenience of equipment use. More importantly, excessive steam escape may cause the risk of scalding to users. This safety hazard has become an important technical bottleneck restricting the development of steamer products.

[0003] In the prior art, conventional solutions to reduce the exhaust volume of steamers are mainly divided into two categories: 1. Steam generation control solution, which reduces steam emissions by precisely controlling the output of the steam generator, but this technical route has fundamental defects. Since the food steaming process requires sufficient steam to ensure heat exchange efficiency, excessive restriction of steam output can easily lead to cooking quality problems such as uneven heating of food and insufficient maturity, especially when processing large-volume ingredients. This contradiction is particularly prominent. 2. Steam condensation treatment solution, using a condensation box structure to cool the exhaust steam. However, this technical solution has two significant defects: first, under long-term cooking conditions, the condensation box is prone to temperature saturation due to the accumulation of heat load, resulting in a sharp attenuation of the condensation efficiency in the later stage; second, when the equipment needs to perform functions such as fruit and vegetable drying and meat air drying that require active dehumidification, the existing condensation structure will hinder moisture discharge, resulting in low drying efficiency or even functional failure. This functional compatibility defect seriously restricts the multifunctional development of steamer products.

[0004] Therefore, how to achieve continuous and efficient steam condensation processing while ensuring the demand for cooking steam, while taking into account the adaptability of the equipment to multiple operating conditions, has become a key issue that urgently needs to be broken through in the field of steamer technology.

[0041] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The structural schematic diagrams of the cooking device 100 in one embodiment of the present application at different viewing angles are respectively shown. The cooking device 100 provided in one embodiment of the present application can be a steamer, a steam oven, or any existing device with a cooking function.

[0042] like Figure 1 and Figure 2 As shown, the cooking device 100 includes an inner pot 110, an exhaust assembly 120 and a condensing assembly 130, wherein the inner pot 110 is provided with a cooking cavity 111, and also includes an upper mounting plate 112 located at the top, the exhaust assembly 120 and the condensing assembly 130 are both mounted on the upper mounting plate 112 to separate them from the portion of the inner pot 110 where the cooking cavity 111 is opened, so as to prevent the heat in the cooking cavity 111 from interfering with the normal operation of the exhaust assembly 120 and the condensing assembly 130.

[0043] like Figure 2 As shown, the exhaust assembly 120 is provided with an exhaust passage 121 connecting the cooking cavity 111 and the outside. It can be understood that the exhaust assembly 120 includes a portion of the pipeline, but the actual structure of the pipeline is not shown in the drawings of this specification, but is illustrated by bold yellow lines, which is only for illustration and not for limitation. Figure 3 As shown, Figure 3A top view schematic diagram of a cooking device 100 in an embodiment of the present application is shown, and the exhaust component 120 includes an exhaust fan 122 acting on the airflow in the exhaust channel 121, and the exhaust fan 122 is used to drive the airflow in the exhaust channel 121 to flow from the cooking cavity 111 toward the outside.

[0044] like Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, the exhaust assembly 120 also includes an air guide plate 123, and the air guide plate 123 is covered on the top of the inner liner 110 to jointly define a portion of the exhaust channel 121. In this embodiment, the air guide plate 123 and the upper mounting plate 112 jointly define a portion of the exhaust channel 121, and the air outlet of the exhaust fan 122 is located in the exhaust channel 121 defined by the air guide plate 123 and the inner liner 110.

[0045] like Figure 2 and Figure 3 As shown, the condensation assembly 130 includes a liquid source 131, a connecting pipe 132 and a condensation plate 133 that defines a portion of the exhaust passage 121. When the airflow in the exhaust passage 121 flows through the condensation plate 133, heat exchange occurs between the condensation plate 133 and the airflow, so that the airflow from the cooking chamber 111 is cooled and condensed by the condensation plate 133, and the airflow from the cooking chamber 111, that is, the steam in the high-temperature steam is partially liquefied and condensed, thereby reducing the water vapor content in the high-temperature gas discharged. In this specification, water is used as the liquid for illustration, but it is not intended to be limiting, and it may also be other cooling liquids. It should be noted that the actual structure of the entire connecting pipe 132 is not shown in the drawings of this specification, and the parts not actually shown are illustrated with bold black lines, which are only for illustration and not for limitation.

[0046] like Figure 3 and Figure 4 As shown, the condensation plate 133 is provided with a liquid flow channel 1331 inside, and the liquid source 131 and the liquid flow channel 1331 are connected as shown in FIG. Figure 3 and Figure 4 The connecting pipe 132 shown is connected to form a circulation loop so that the liquid in the liquid source 131 and the condensation plate 133 can circulate continuously, thereby continuously replenishing the liquid with lower temperature for the liquid flow channel 1331 in the condensation plate 133 through the liquid source 131, thereby avoiding the condensation efficiency being reduced after the condensation plate 133 absorbs the heat of the air flow in the exhaust channel 121.

[0047] like Figure 5 and Figure 6As shown, at least part of the connecting pipe 132 is located in the exhaust channel 121 and downstream of the exhaust fan 122, so that the cold wind of the exhaust fan 122 can act on the connecting pipe 132 located in the exhaust channel 121, and the connecting pipe 132 located in the exhaust channel 121 is made of heat-conducting material, so as to cool the liquid circulating in the liquid source 131 and the condensation plate 133, and then use the wind force of the exhaust fan 122 to cool the condensation plate 133, so that the condensation plate 133 is kept at a reduced temperature state, so that the condensation plate 133 can be continuously and efficiently condensed. Since the circulating liquid is continuously circulated, and the exhaust fan 122 is in a state of continuous operation and has a strong cooling capacity, it is possible to continuously cool the condensation plate 133 and maintain a relatively ideal condensation state.

[0048] like Figure 5 and Figure 6 As shown, in one embodiment, the connecting pipe 132 includes a cooling pipe 1321 located in the exhaust channel 121, and the setting direction of the cooling pipe 1321 is at an angle to the flow direction of the airflow in the exhaust channel 121, so that the airflow in the exhaust channel 121 can blow more through the surface of the cooling pipe 1321, thereby improving the cooling effect of the wind force of the exhaust fan 122 on the circulating liquid, and further improving the cooling effect of the circulating liquid on the condensation plate 133, so that the condensation plate 133 can continuously and efficiently condense.

[0049] like Figure 6 and Figure 7 As shown, in one embodiment, the cooling pipe 1321 includes a plurality of bending structures 13211 connected end to end, and each bending structure 13211 includes an upstream section and a downstream section arranged at an angle. The upstream section of a bending structure 13211 is connected to the downstream section of another bending structure 13211, and so on, thereby forming a cooling pipe 1321 having a plurality of bending structures 13211, thereby increasing the airflow in the exhaust channel 121 to be able to blow more over the surface of the cooling pipe 1321, thereby improving the cooling effect of the wind force of the exhaust fan 122 on the circulating liquid, and further improving the cooling effect of the circulating liquid on the condensation plate 133, so that the condensation plate 133 can be continuously and efficiently condensed.

[0050] like Figure 6 As shown, in one embodiment, the connecting pipe 132 penetrates the exhaust channel 121 in a direction at an angle to the flow direction of the airflow in the exhaust channel 121, so as to facilitate the connection of the liquid source 131 and the condensation plate 133 located outside the exhaust channel 121. In this embodiment, the liquid source 131 and the condensation plate 133 are both located outside the air guide plate 123, and the cooling pipe 1321 is in the exhaust channel 121 formed between the air guide plate 123 and the upper mounting plate 112.

[0051] like Figure 6 As shown, in one embodiment, the connecting pipe 132 located in the exhaust channel 121 is located at the air outlet of the exhaust fan 122, so that the cold air of the exhaust fan 122 can act on the connecting pipe 132 located in the exhaust channel 121. In the embodiment illustrated in this specification, the cold air of the exhaust fan 122 can act on the cooling pipe 1321.

[0052] like Figure 4 As shown, in one embodiment, the condensation assembly 130 further includes a condensation box 134 with a hollow interior. Figure 2 As shown, the condensation box 134 is fixedly connected to the upper mounting plate 112. For example, in this embodiment, the condensation box 134 is fixed to the upper mounting plate 112 by four mounting legs. The condensation box 134 is provided with an air inlet 1341 and an air outlet 1342. The condensation plate 133 is covered on the condensation box 134 to jointly define a part of the exhaust passage 121. Figure 2 As shown, on the air flow path in the exhaust channel 121, the exhaust fan 122 is located downstream of the condensation box 134, so that the airflow in the cooking cavity 111 is first cooled by the condensation plate 133, and then enters the exhaust channel 121 corresponding to the air guide plate 123 through the exhaust fan 122, thereby making it easier for the airflow to cool the cooling pipe 1321 and the circulating liquid therein, thereby improving the effect of the circulating liquid cooling the condensation plate 133, thereby achieving continuous and efficient condensation of the condensation plate 133.

[0053] like Fig.10 As shown, in one embodiment, the condensation assembly 130 also includes a partition 135, which is located inside the condensation box 134 and is used to define the exhaust channel 121 between the air inlet 1341 and the air outlet 1342, so as to extend the length of the exhaust channel 121 between the air inlet 1341 and the air outlet 1342, thereby improving the contact between the airflow and the condensation plate 133, thereby improving the cooling and condensation effect of the condensation plate 133 on the airflow, extending its condensation time in the condensation box 134, and avoiding its premature escape in an uncondensed state.

[0054] like Fig.10As shown, in one embodiment, the air inlet 1341 and the air outlet 1342 are opened on the same end face of the condensation box 134, and the partition 135 is vertically arranged on the end face where the air inlet 1341 is located, the partition 135 extends in the direction away from the end face where the air inlet 1341 is located, and there is a gap between the end of the partition 135 away from the air inlet 1341 and the end face of the condensation box 134 opposite to the air inlet 1341, so that after the airflow enters through the air inlet 1341, it needs to go around the partition 135 before it can flow out through the air outlet 1342, so as to prolong the contact between the airflow and the condensation plate 133, thereby improving the cooling and condensation effect of the condensation plate 133 on the airflow, prolonging its condensation time in the condensation box 134, and avoiding its premature escape in an uncondensed state.

[0055] like Figure 4 As shown, in one embodiment, the condensation plate 133 is covered on the top of the condensation box 134, and the bottom surface 1343 of the condensation box 134 is an inclined surface inclined at an upward slope in the extension direction of the partition 135, so that the condensed water formed by the cooling and condensation of the condensation plate 133 can be gathered at the air inlet 1341, and it is convenient to flow back to the cooking cavity 111.

[0056] like Figure 4 As shown, in one embodiment, the bottom surface 1343 of the condensation box 134 is an inclined surface inclined at a downward slope in the direction from the air outlet 1342 to the air inlet 1341, so that the condensed water formed by the cooling and condensation of the air flow on the condensation plate 133 is gathered at the air inlet 1341, and is convenient for returning to the cooking cavity 111.

[0057] like Figure 2 and Figure 3 As shown, in one embodiment, the condensation component 130 also includes a liquid flow valve 136, which is connected to the connecting pipe 132 and is used to control the connection of the connecting pipe 132. When the connecting pipe 132 is disconnected, the liquid in the condensation plate 133 absorbs the heat of the airflow in the exhaust duct for a long time. The condensation plate 133 cannot cool down by circulating and replenishing liquid with a lower temperature, and will not hinder moisture discharge, thereby adapting to various working conditions such as drying residual water, dried vegetables and fruits, and dried meat.

[0058] like Figure 2 and Figure 3As shown, in one embodiment, the condensing assembly 130 further includes a liquid flow pump 137, which is connected to the connecting pipe 132 and is used to drive the fluid flow in the connecting pipe 132. It can be understood that the circulation of the liquid in the liquid source 131 and the condensing plate 133 is largely achieved through the action of the liquid flow pump 137. Therefore, when the condensing plate 133 is not needed to maintain its condensation efficiency, such as the various working conditions such as the above-mentioned drying of residual water, dried vegetables and fruits, and dried meat, turning off the liquid flow pump 137 can also play a role.

[0059] like Figure 2 and Figure 4 As shown, in one embodiment, the condensing assembly 130 also includes a heat dissipation fin 138, which is connected to the end surface of the condensing plate 133 facing away from the exhaust channel 121. The heat dissipation fin 138 increases the area of ​​the heat exchange surface so that more heat can come into contact with the air, thereby accelerating the heat dissipation of the condensing plate 133.

[0060] like Figure 2 and Figure 4 As shown, in one embodiment, the condensing assembly 130 further includes a heat dissipation fan 139, which is connected to the end surface of the condensing plate 133 away from the exhaust passage 121, and the heat dissipation fan 139 acts on the condensing plate 133 and / or the heat dissipation fins 138. Figure 4 As shown, in this embodiment, the heat dissipation fan 139 acts on the heat dissipation fins 138, forcing air to flow through the surface of the heat dissipation fins 138 to form forced convection. Compared with natural convection, forced convection can significantly increase the air flow rate, thereby accelerating the transfer of heat. The airflow provided by the heat dissipation fan 139 can quickly take away the heat on the surface of the heat dissipation fins 138, further reducing the temperature of the condensation plate 133. In other embodiments, the heat dissipation fan 139 can also directly act on the condensation plate 133 to cool the condensation plate 133 through the cold air generated by itself.

[0061] like Figure 8 and Fig. 9As shown, in one embodiment, the condensation plate 133 includes an upper plate 1332 and a lower plate 1333 that are arranged opposite to each other, the upper plate 1332 is recessed with a first groove 13321, and the lower plate 1333 is recessed with a second groove 13331 that is arranged opposite to the first groove 13321, so as to facilitate the processing of the condensation plate 133. The upper plate 1332 and the lower plate 1333 are interlocked, and the first groove 13321 and the second groove 13331 together form a liquid flow channel 1331. In other embodiments, the liquid flow channel 1331 in the condensation plate 133 may also adopt other structures without limitation. In this embodiment, an interlayer with a leak-proof function is sandwiched between the upper plate 1332 and the lower plate 1333, such as a sealing ring, and the interlayer is located at the position where the first groove 13321 and the second groove 13331 are not provided on the upper plate 1332 and the lower plate 1333. As shown Figure 8 and Fig. 9 As shown, in this embodiment, the liquid flow channel 1331 is a plurality of continuous U-shaped structures, but this is not limited. Figure 8 and Fig. 9 As shown, in this embodiment, the liquid flow channel 1331 covers almost the entire position of the condensation plate 133 to effectively exchange heat with the condensation plate 133 to cool it down.

[0062] The cooking device 100 provided in the above scheme has a condensation plate 133 disposed on the exhaust path of the cooking cavity 111, and heat dissipation fins 138 and a heat dissipation fan 139 are disposed on the surface of the condensation plate 133 to initially cool down the condensation plate 133, and a liquid flow channel 1331 with circulating liquid is disposed inside the condensation plate 133, and the circulating liquid in the liquid flow channel 1331 cools down the condensation plate 133 for a second time, so that the liquid flow channel 1331 in the condensation plate 133 is continuously replenished with liquid of lower temperature through the liquid source 131, thereby preventing the condensation plate 133 from cooling down after absorbing the heat of the airflow in the exhaust channel 121 The condensation efficiency is reduced; the connecting pipe 132 that connects the condensation plate 133 and the liquid source 131 as a circulation loop is partially arranged on the exhaust path and downstream of the exhaust fan 122, so that the cold air of the exhaust fan 122 can act on the connecting pipe 132 located in the exhaust channel 121, so that the cold air of the exhaust fan 122 can cool the liquid circulating in the liquid source 131 and the condensation plate 133, and then the wind force of the exhaust fan 122 is used to cool the condensation plate 133, so that the condensation plate 133 is kept at a lowered temperature state, so that the condensation plate 133 can continue to condense efficiently.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0064] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
