Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to a cooking device. BACKGROUND

[0002] As an important steam cooking device in modern kitchens, steam ovens have been widely used due to their convenience, professionalism and intelligent features. With the continuous improvement of users' requirements for cooking experience, the steam discharge control problem during the operation of steam ovens has attracted increasing attention. The exhaust volume of a steam oven, as a key indicator of device performance, directly affects the safety, energy efficiency and user experience. Excessive exhaust volume not only leads to an increase in humidity in the kitchen environment, causing safety hazards such as mold growth and condensate accumulation of kitchen utensils, but also significantly increases the frequency of water tank refilling, affecting the convenience of device use. More importantly, excessive steam escape can cause user scalding risk, which has become an important technical bottleneck restricting the development of steam oven products.

[0003] In the prior art, the conventional solutions to reduce the exhaust volume of a steam oven mainly fall into two categories: 1. Steam generation control scheme, which reduces steam discharge by precisely regulating the output of the steam generator. However, this technical route has a fundamental flaw. Since the food steaming process requires sufficient steam volume to ensure heat exchange efficiency, excessive restriction of steam output can easily lead to uneven heating of food, insufficient maturity and other cooking quality problems, especially when handling large capacity of food materials. 2. Steam condensation treatment scheme, which uses a condensing box structure to cool the discharged steam. However, this technical solution has two significant defects: first, under long-term cooking conditions, the condensing box is prone to reach temperature saturation due to heat load accumulation, resulting in a sharp decline in condensation efficiency in the later period; second, when the device needs to perform functions such as fruit and vegetable drying, meat drying, etc. that require active moisture discharge, the existing condensing structure will hinder moisture discharge, causing low drying efficiency or even functional failure. This functional compatibility defect seriously restricts the development of multifunctional steam oven products.

[0041] Referring to Figure 1 and Figure 2 , Figure 1 and Figure 2 respectively show the structural schematic diagram of the cooking device 100 in different viewing angles in an embodiment of the present application. The cooking device 100 provided by the embodiment of the present application can be a steamer, a steam oven, or any existing device with cooking function.

[0042] As shown in Figure 1 and Figure 2 , the cooking device 100 includes an inner container 110, an exhaust assembly 120 and a condensation assembly 130. The inner container 110 is provided with a cooking cavity 111 and further includes an upper mounting plate 112 at the top. The exhaust assembly 120 and the condensation assembly 130 are both mounted on the upper mounting plate 112 to be separated from the part of the inner container 110 where the cooking cavity 111 is opened, so as to avoid the heat in the cooking cavity 111 interfering with the normal work of the exhaust assembly 120 and the condensation assembly 130.

[0043] As shown in Figure 2 , the exhaust assembly 120 is provided with an exhaust passage 121 which is communicated with the cooking cavity 111 and the outside. It can be understood that the exhaust assembly 120 includes part of the pipeline, but the actual structure of the pipeline is not shown in the drawings of the present application, and is only schematically shown by thick yellow lines without limitation. In combination with Figure 3 shown, Figure 3The top view of the cooking device 100 in one embodiment of the present application is shown, the exhaust assembly 120 includes an exhaust fan 122 acting on the airflow in the exhaust channel 121, the exhaust fan 122 is used to drive the airflow in the exhaust channel 121 to flow from the cooking cavity 111 to the outside.

[0044] As shown in Figure 3 , Figure 5 and Figure 6 , in one embodiment, the exhaust assembly 120 further includes a baffle 123, the baffle 123 covers the top of the inner container 110 to jointly define part of the exhaust channel 121, in the present embodiment, the baffle 123 and the upper mounting plate 112 jointly define part of the exhaust channel 121, and the air outlet of the exhaust fan 122 is located in the exhaust channel 121 defined by the baffle 123 and the inner container 110.

[0045] As shown in Figure 2 and Figure 3 , the condensing assembly 130 includes a liquid source 131, a connecting pipe 132 and a condensing plate 133 defining part of the exhaust channel 121, when the airflow in the exhaust channel 121 flows through the condensing plate 133, heat exchange occurs between the condensing plate 133 and the airflow, so that the airflow from the cooking cavity 111 is cooled and condensed by the condensing plate 133, the steam in the high-temperature steam from the cooking cavity 111 is liquefied and condensed, and the water vapor content in the exhaust high-temperature gas is reduced. In this specification, water is used as the liquid for illustration, but it is not limited to this, it can also be other cooling liquids. It should be noted that the actual structure of all connecting pipes 132 is not shown in the drawings of the present specification, the part not actually shown is shown by thick black lines for illustration only and is not limited.

[0046] As shown in Figure 3 and Figure 4 , the condensing plate 133 is internally provided with a liquid flow passage 1331, the liquid source 131 and the liquid flow passage 1331 are connected in communication through the connecting pipe 132 as shown in Figure 3 and Figure 4 , to form a circulation loop, so that the liquid in the liquid source 131 and the condensing plate 133 can circulate continuously, thereby continuously supplementing the liquid flow passage 1331 in the condensing plate 133 with lower temperature liquid from the liquid source 131, thereby avoiding the condensing plate 133 from reducing the condensing efficiency after absorbing the heat of the airflow in the exhaust channel 121.

[0047] As shown in Figure 5 and Figure 6As shown, at least part of the connecting pipe 132 is located in the exhaust air passage 121 and downstream of the exhaust air fan 122, so that the cold air of the exhaust air fan 122 can act on the connecting pipe 132 located in the exhaust air passage 121, and the connecting pipe 132 located in the exhaust air passage 121 is made of a heat-conducting material, thereby cooling the liquid circulating in the liquid source 131 and the condensing plate 133, and achieving the cooling of the condensing plate 133 by using the wind power of the exhaust air fan 122, so that the condensing plate 133 can be kept at a lower temperature, thereby achieving the continuous and efficient condensation of the condensing plate 133. Since the circulating liquid is continuously circulated, and the exhaust air fan 122 is always in operation and has strong cooling capacity, the condensing plate 133 can be continuously cooled and kept in an ideal condensing state.

[0048] As shown in Figure 5 and Figure 6 In one embodiment, the connecting pipe 132 includes a cooling pipe 1321 located in the exhaust air passage 121, and the cooling pipe 1321 is arranged at an angle to the flow direction of the air flow in the exhaust air passage 121, so that the air flow in the exhaust air passage 121 can blow more on the surface of the cooling pipe 1321, thereby improving the cooling effect of the circulating liquid by the wind power of the exhaust air fan 122, and further improving the cooling effect of the circulating liquid on the condensing plate 133, so that the condensing plate 133 can be continuously and efficiently condensed.

[0049] As shown in Figure 6 and Figure 7 In one embodiment, the cooling pipe 1321 includes a plurality of first and last bending structures 13211, each bending structure 13211 includes an upstream segment and a downstream segment arranged at an angle. The upstream segment of one bending structure 13211 is connected to the downstream segment of another bending structure 13211, and the same applies to the subsequent bending structures 13211, thereby forming a cooling pipe 1321 with a plurality of bending structures 13211, thereby increasing the air flow in the exhaust air passage 121 that can blow more on the surface of the cooling pipe 1321, thereby improving the cooling effect of the circulating liquid by the wind power of the exhaust air fan 122, and further improving the cooling effect of the circulating liquid on the condensing plate 133, so that the condensing plate 133 can be continuously and efficiently condensed.

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

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

[0052] As shown in Figure 4 In one of the embodiments, the condensing assembly 130 further comprises a hollow condensing box 134. In the embodiment, as shown in Figure 2 The condensing box 134 is fixedly connected to the upper mounting plate 112. For example, in the embodiment, the condensing box 134 is fixed to the upper mounting plate 112 by four mounting legs. The condensing box 134 is provided with an air inlet 1341 and an air outlet 1342. The condensing plate 133 is provided on the condensing box 134 to jointly define part of the exhaust air passage 121. As shown in Figure 2 In the airflow flow path in the exhaust air passage 121, the exhaust air fan 122 is located downstream of the condensing box 134, so that the airflow in the cooking cavity 111 first passes through the cooling of the condensing plate 133, and then passes through the exhaust air fan 122 into the exhaust air passage 121 corresponding to the air guide plate 123, thereby more conveniently cooling the cooling pipe 1321 and the circulating liquid inside it by the airflow, thereby improving the cooling effect of the circulating liquid on the condensing plate 133, thereby realizing the continuous and efficient condensation of the condensing plate 133.

[0053] As shown in Figure 10 In one of the embodiments, the condensing assembly 130 further comprises a partition plate 135 located inside the condensing box 134 and used to define the exhaust air passage 121 between the air inlet 1341 and the air outlet 1342, so as to prolong the length of the exhaust air passage 121 between the air inlet 1341 and the air outlet 1342, thereby improving the contact between the airflow and the condensing plate 133, thereby improving the cooling and condensing effect of the condensing plate 133 on the airflow, prolonging the condensation time of the condensing plate 133 in the condensing box 134, and avoiding its premature escape in the uncondensed state.

[0054] As shown in Figure 10As shown in the drawings, in one embodiment, the air inlet 1341 and the air outlet 1342 are arranged on the same end surface of the condensing box 134, and the partition plate 135 is arranged vertically on the end surface where the air inlet 1341 is located. The partition plate 135 extends towards the direction away from the end surface where the air inlet 1341 is located, and the end of the partition plate 135 away from the air inlet 1341 has a gap with the end surface of the condensing box 134 opposite to the air inlet 1341. After the airflow enters through the air inlet 1341, it needs to pass behind the partition plate 135 before it can flow out through the air outlet 1342, so as to prolong the contact between the airflow and the condensing plate 133, thereby improving the cooling and condensing effect of the condensing plate 133 on the airflow, prolonging the condensing time of the airflow in the condensing box 134, and avoiding the premature escape of the airflow in the uncondensed state.

[0055] As shown in the drawings, Figure 4 In one embodiment, the condensing plate 133 is arranged on the top of the condensing box 134, and the bottom surface 1343 of the condensing box 134 is an inclined surface inclined with an upward slope in the direction along the extension of the partition plate 135, so as to facilitate the condensate formed by the cooling and condensing of the airflow by the condensing plate 133 to collect at the air inlet 1341 and flow back into the cooking cavity 111.

[0056] As shown in the drawings, Figure 4 In one embodiment, the bottom surface 1343 of the condensing box 134 is an inclined surface inclined with a downward slope in the direction from the air outlet 1342 to the air inlet 1341, so as to facilitate the condensate formed by the cooling and condensing of the airflow by the condensing plate 133 to collect at the air inlet 1341 and flow back into the cooking cavity 111.

[0057] As shown in the drawings, Figure 2 and Figure 3 In one embodiment, the condensing assembly 130 further includes a liquid flow valve 136 connected to the connecting pipeline 132 and used to control the opening and closing of the connecting pipeline 132. When the connecting pipeline 132 is disconnected, the liquid in the condensing plate 133 cannot be cooled by circulating lower-temperature liquid after absorbing the heat of the airflow in the exhaust air duct for a long time, so as not to hinder the moisture discharge, thereby realizing the adaptation to various working conditions such as the function of drying residual water, vegetable and fruit drying, and meat drying.

[0058] As shown in the drawings, Figure 2 and Figure 3As shown in FIG. 1 1, in one embodiment, the condensing assembly 130 further comprises a liquid flow pump 137 connected to the connecting pipe 132 and 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 by the liquid flow pump 137. Therefore, when the condensing plate 133 does not need to maintain its condensing efficiency, for example, in the above-mentioned various working conditions such as drying residual water, dried vegetables, dried fruits, dried meat, and the like, the liquid flow pump 137 can be turned off.

[0059] As shown in FIG. 12, Figure 2 and Figure 4 As shown in FIG. 13, in one embodiment, the condensing assembly 130 further comprises a heat dissipation fin 138 connected to the end surface of the condensing plate 133 away from the air outlet channel 121. The heat dissipation fin 138 increases the area of the heat exchange surface, so that more heat can be in contact with the air, thereby accelerating the heat dissipation of the condensing plate 133.

[0060] As shown in FIG. 14, Figure 2 and Figure 4 As shown in FIG. 15, in one embodiment, the condensing assembly 130 further comprises a heat dissipation fan 139 connected to the end surface of the condensing plate 133 away from the air outlet channel 121, and the heat dissipation fan 139 acts on the condensing plate 133 and / or the heat dissipation fin 138. As shown in FIG. 16, Figure 4 In this embodiment, the heat dissipation fan 139 acts on the heat dissipation fin 138, forcing air to flow through the surface of the heat dissipation fin 138, forming forced convection. Compared with natural convection, forced convection can significantly increase the flow rate of air, thereby accelerating the heat transfer. The air flow provided by the heat dissipation fan 139 can quickly take away the heat on the surface of the heat dissipation fin 138, further reducing the temperature of the condensing plate 133. In other embodiments, the heat dissipation fan 139 can also act directly on the condensing plate 133 to cool the condensing plate 133 by itself.

[0061] As shown in FIG. 17, Figure 8 and Figure 9As shown, in one embodiment, the condensing plate 133 comprises oppositely arranged upper plate 1332 and lower plate 1333, the upper plate 1332 is concavely provided with a first groove 13321, and the lower plate 1333 is concavely provided with a second groove 13331 oppositely arranged with the first groove 13321, so as to facilitate the processing of the condensing plate 133. The upper plate 1332 and the lower plate 1333 are buckled, and the first groove 13321 and the second groove 13331 jointly form a liquid flow channel 1331. In other embodiments, the liquid flow channel 1331 in the condensing plate 133 can also adopt other structures, which are not limited. In the present embodiment, a clamping layer with a leak-proof function is clamped between the upper plate 1332 and the lower plate 1333, for example, a sealing ring or the like, and the clamping layer is located at the position of the upper plate 1332 and the lower plate 1333 which is not provided with the first groove 13321 and the second groove 13331. As shown in Figure 8 and Figure 9 As shown, in the present embodiment, the liquid flow channel 1331 has a plurality of continuous U-shaped structures, but is not limited. As shown in Figure 8 and Figure 9 As shown, in the present embodiment, the liquid flow channel 1331 almost covers the entire position of the condensing plate 133, so as to effectively exchange heat with the condensing plate 133 to cool it down.

[0062] The cooking equipment 100 provided in the above scheme, by arranging the condensing plate 133 on the exhaust path of the cooking cavity 111, and arranging the heat dissipation fins 138 and the heat dissipation fan 139 on the surface of the condensing plate 133 to preliminarily cool and cool the condensing plate 133, and arranging the liquid flow channel 1331 with circulating liquid in the interior of the condensing plate 133, the circulating liquid in the liquid flow channel 1331 secondary cools the condensing plate 133, so as to continuously supplement the liquid flow channel 1331 in the condensing plate 133 with lower temperature liquid through the liquid source 131, so as to avoid the condensing plate 133 to reduce the condensing efficiency after absorbing the heat of the airflow in the exhaust passage 121; and by arranging the connecting pipeline 132 connecting the condensing plate 133 and the liquid source 131 as a circulating loop 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 pipeline 132 located in the exhaust passage 121, thereby cooling the liquid circulating in the liquid source 131 and the condensing plate 133 through the cold air of the exhaust fan 122, and then realizing the cooling of the condensing plate 133 by borrowing the air power of the exhaust fan 122, so as to realize that the condensing plate 133 is kept in a reduced temperature state, so as to realize that the condensing plate 133 can continuously and efficiently condense.

[0063] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present disclosure.

[0064] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a more specific and detailed manner, but should not be construed as limiting the scope of the patent application. It should be noted that, for those of ordinary skill in the art, several modifications 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.
