[0044] Please refer to Figure 1-Figure 3 This embodiment provides a cooking appliance 100, which includes a cooktop module 110, a range hood module 120, and a refrigeration module 130.

[0045] The range hood module 120 and the refrigeration module 130 are both located below the cooktop module 110; the range hood module 120 includes a range hood body 121 and a flue 122, the flue 122 being connected to the range hood body 121; the refrigeration module 130 includes a refrigeration body 131 and an air supply duct 132, the air supply duct 132 being connected to the refrigeration body 131.

[0046] The flue 122 and the air supply duct 132 are both located on the rear side of the cooktop module 110 and extend to the area above the cooktop module 110.

[0047] Please refer to Figure 1-Figure 3 The working principle of this cooking appliance 100 is as follows:

[0048] The cooking appliance 100 includes a cooktop module 110, a range hood module 120, and a refrigeration module 130;

[0049] The cooktop module 110 is used for cooking by the user, the range hood module 120 can extract the fumes generated during cooking, and the cooling module 130 can improve the ambient temperature.

[0050] Specifically, when configuring the cooktop module 110, range hood module 120, and refrigeration module 130, a structural arrangement is adopted in which the range hood module 120 and refrigeration module 130 are both located below the cooktop module 110. The purpose is to enable the integrated cooking appliance 100 to make reasonable use of the space in the lower cabinet area of ​​the kitchen, thereby improving its installation and usage flexibility. Moreover, when configuring the range hood module 120 and refrigeration module 130, their size parameters can be adjusted according to their structural configuration, so that a steam oven or oven can be added between or above and below the range hood module 120 and refrigeration module 130, thereby enriching the functions of the integrated cooking appliance 100.

[0051] Furthermore, when configuring the range hood module 120, the range hood module 120 includes a range hood body 121 and a flue 122, with the flue 122 connected to the range hood body 121; when configuring the refrigeration module 130, the refrigeration module 130 includes a refrigeration body 131 and an air supply duct 132, with the air supply duct 132 connected to the refrigeration body 131; and both the flue 122 and the air supply duct 132 are located on the rear side of the cooktop module 110 and extend towards the area above the cooktop module 110; thus, through this arrangement, the flue 122 and the air supply duct 132 can be positioned opposite each other on the wall side of the integrated cooking appliance 100, thereby avoiding the flue 122... The air supply duct 132 does not affect the normal use of the user, but can make more reasonable use of space and improve the overall aesthetics of the cooking appliance 100. Furthermore, since the flue 122 and the air supply duct 132 extend to the area above the cooktop module 110, the flue 122 can draw in the smoke generated by the cooktop module 110 during operation. At the same time, during the air supply process, the air supply duct 132 can adjust the ambient temperature to maintain it at a comfortable temperature for the user, and can also form an air curtain in the area of ​​the cooking appliance 100 to reduce the loss of air. Meanwhile, the smoke in the air curtain can be collected by the range hood module 120.

[0052] In summary, this cooking appliance 100 can improve the ambient temperature and reduce the emission of fumes during use, thereby reducing the impact on the user's health. In addition, it can also improve the user experience by improving the ambient temperature.

[0053] Further, please refer to Figures 1-6 In this embodiment, during the use of the cooking appliance 100, depending on the working state of the stove module 110 and the temperature of the surrounding environment, the air outlet direction of the air supply duct 132 can be adjusted to flexibly form an air curtain around the cooking appliance 100 and improve the ambient temperature. Specifically, the cooling module 130 may also include a movable air guide plate 133 and a rotating motor 134.

[0054] The movable air guide plate 133 is rotatably connected to the air outlet 101 of the air supply duct 132; the rotating motor 134 is driven by the movable air guide plate 133 and is used to drive the movable air guide plate 133 to rotate relative to the air outlet 101, so as to adjust the air outlet angle of the air outlet 101. Figure 5 and Figure 6 (This shows the airflow direction of the movable air guide plate 133 at different angles).

[0055] The purpose of this configuration is to allow the airflow direction of the air duct 132 to be flexibly adjusted according to the usage status and ambient temperature through the movable air guide. The adjustment can be achieved by having the movable air guide plate 133 reciprocate relative to the air outlet 101, that is, by sweeping the air to increase the rate of decrease in ambient temperature; or by adjusting it to a fixed angle, that is, by directing the airflow so that the airflow delivered by the air duct 132 can form an air curtain around the cooktop module 110 or the integrated cooking appliance 100 to reduce the escape of smoke, or by forming an air curtain in front of the user activity area of ​​the integrated cooking appliance 100 to reduce the temperature of the user activity area, improve the user's comfort experience, and at the same time reduce the escape of smoke and heat generated by the cooktop module 110.

[0056] It should be noted that, based on the above, when configuring the air outlet 101 of the air supply duct 132, it can be positioned above the smoke inlet 104 of the flue 122 and tilted towards the area where the user is active. The purpose is to make its air supply range cover the front of the cooking appliance 100, thereby enabling its air supply range to cover the outer perimeter of the cooking appliance 100, i.e., the area where the user is active. At the same time, combined with the aforementioned movable air guide plate 133, its air supply range can be expanded.

[0057] Further, please refer to Figures 1-8 , Figure 8 The airflow direction of the refrigeration body 131 in this embodiment is shown. The refrigeration body 131 includes a refrigeration housing 135, a compressor 136, a condenser 137, a heat exhaust fan 138, a circulating fan 139, and an evaporator 141. During installation, to facilitate the installation of the compressor 136, condenser 137, heat exhaust fan 138, circulating fan 139, and evaporator 141, the refrigeration housing 135 is divided into a first chamber 142 and a second chamber 143. The first chamber 142 comprises a chamber 143 and a heat exhaust chamber 144. The compressor 136, condenser 137, and heat exhaust fan 138 are all located in the first chamber 142, while the circulating fan 139 and evaporator 141 are located in the second chamber 143. The circulating fan 139 is connected to the air inlet of the air supply duct 132. The heat exhaust chamber 144 is connected to the first chamber 142. Heat exhaust ports 102, connected to the heat exhaust chamber 144, are located on one side or opposite sides of the refrigeration housing 135. This arrangement simplifies the structural design of the refrigeration unit 131 and optimizes its dimensions, facilitating its integration with the cooktop module 110 and the range hood module 120.

[0058] It should be noted that the working principles of compressor 136, condenser 137, exhaust fan 138, circulating fan 139 and evaporator 141 are the same as those of existing technology, so they will not be described in detail here.

[0059] When configuring the main body 121 of the range hood, please refer to... Figures 1-9 The main body 121 of the range hood includes a range hood housing 123, a smoke extraction fan 124, a smoke exhaust pipe 125, and an oil box 126. The smoke extraction fan 124 and the smoke exhaust pipe 125 are both housed within the range hood housing 123. The inlet of the smoke extraction fan 124 is connected to the flue 122, and the outlet of the smoke extraction fan 124 is connected to the smoke exhaust pipe 125. The oil box 126 is movably connected to the range hood housing 123 and is used to collect the oil discharged by the smoke extraction fan 124. Smoke exhaust ports 103 connected to the smoke exhaust pipe 125 are located on one side or opposite sides of the range hood housing 123. This structural design optimizes its dimensions, facilitates integration with the cooktop module 110 and the refrigeration module 130, and also facilitates the collection and treatment of oil in the flue gas.

[0060] Based on the above-mentioned structural configuration of the refrigeration body 131 and the range hood body 121, since the refrigeration housing 135 is provided with a heat exhaust port 102 communicating with the heat exhaust chamber 144 on one side or opposite sides, and the range hood housing 123 is provided with a smoke exhaust port 103 communicating with the smoke exhaust pipe 125 on one side or opposite sides, the smoke exhaust and heat exhaust pipes can be conveniently installed according to the actual installation site. Moreover, to improve its versatility, this embodiment adopts the configuration that the refrigeration housing 135 is provided with a heat exhaust port 102 communicating with the heat exhaust chamber 144 on opposite sides, and the range hood housing 123 is provided with a smoke exhaust port 103 communicating with the smoke exhaust pipe 125 on opposite sides. With this configuration, the smoke exhaust port 103 and heat exhaust port 102 communicating with one or both sides can be selected according to the conditions of the smoke exhaust pipe 125 at the installation site. When one side is selected to be connected, the other side can be closed.

[0061] Furthermore, this configuration provides an integrated smoke and heat exhaust structure. That is, provided it meets the structural requirements of the installation site, please refer to [the relevant documentation / reference]. Figures 1-10 The cooking appliance 100 may also include a three-way pipe 150, with two ends of the three-way pipe 150 connected to the heat exhaust port 102 and the smoke exhaust port 103 respectively, and the other end of the three-way pipe 150 connected to the external flue 122; wherein the heat exhaust port 102 and the smoke exhaust port 103 connected to the three-way pipe 150 are located on the same side of the stove; thus, the three-way pipe 150 can be used to connect the heat exhaust port 102 and the smoke exhaust port 103 to the same pipeline, thereby simplifying the configuration of the pipeline structure and reducing the difficulty of on-site installation.

[0062] Further, please refer to Figures 1-10Based on the above structural design, to prevent smoke from escaping during the upward motion, the cooking appliance 100 also includes baffles 160 spaced above the smoke inlets 104 of the flue 122, with the air outlets 101 of the air supply duct 132 located above the baffles 160. This arrangement aims to improve the smoke collection rate of the range hood module 120, thereby reducing the amount of smoke escaping. It should be noted that this arrangement requires the air outlets 101 of the air supply duct 132 to be located above the baffles 160 to prevent the baffles 160 from affecting the air supply range of the air supply duct 132.

[0063] Further, please refer to Figures 1-10 During use, the heat generated by the cooktop module 110 and the outdoor temperature both affect the indoor temperature, which in turn impacts the user experience. Therefore, the cooking appliance 100 also includes a fresh air unit 170 connected to the cooling unit 131, which is connected to the air inlet of the air supply duct 132. This configuration allows the cooking appliance 100 to control the operation of the fresh air unit 170 based on the outdoor temperature. This improves indoor air circulation and utilizes the outdoor temperature to enhance indoor temperature, thereby reducing energy consumption.

[0064] Please refer to Figures 1-12 In this embodiment, the flue 122 and the air supply duct 132 are positioned behind the cooktop module 110. Alternatively, the flue 122 and the air supply duct 132 can be arranged side-by-side, with the flue 122 located in front of the air supply duct 132 (e.g.,...). Figure 11 (as shown); or, the air supply duct 132 passes through the flue 122 (as shown). Figure 12 As shown in the diagram, the outer wall of the air supply duct 132 is spaced apart from the outer wall of the flue 122. This arrangement allows the air supply duct 132 to form an air curtain around the cooking appliance 100 during the air supply process, improving the ambient temperature, while also adjusting the temperature of the flue gas inside the flue 122. The purpose is to lower the temperature of the flue gas inside the flue 122, thereby allowing the oil in the flue gas to condense and be easily collected into the oil box 126.

[0065] In order to improve the intelligence and automation of the cooking appliance 100 during use, and to enable the cooking appliance 100 to automatically adjust its working status according to the working status of its cooktop module 110, indoor temperature and outdoor temperature, the cooking appliance 100 also includes a smoke detection unit connected to the range hood module 120, and an indoor temperature detection unit connected to the outside of the cooktop module 110, the range hood module 120 or the refrigeration module 130. The smoke detection unit is used to detect harmful substances in the smoke generated by the cooktop module 110, and the indoor temperature detection unit is used to detect the indoor temperature where the cooking appliance 100 is located.

[0066] This configuration allows for adaptive adjustments to the operating status of the range hood module 120, cooling module 130, and fresh air unit 170 based on the detection data from the flue gas detection unit and the indoor temperature detection unit, combined with the outdoor temperature data obtained through networking or from an additional outdoor temperature detection unit. This improves the automation and intelligence of the system during use and enhances the user experience.

[0067] It should be noted that when the flue gas detection unit detects harmful substances in the flue gas generated by the stove module 110 during operation, it refers to harmful substances generated during the process of the stove module 110 heating cooking utensils or food, such as benzo[a]pyrene, volatile nitrosamines or heterocyclic amine compounds; it can also be harmful gases such as gas.

[0068] Based on the structure of the cooking appliance 100 described above, when configuring the range hood module 120, refrigeration module 130, and fresh air unit 170 of the cooking appliance 100, they are configured with three speed settings: high, medium, and low. The operating power of the high speed setting is greater than that of the medium speed setting, and the operating power of the medium speed setting is greater than that of the low speed setting. It should be noted that this speed setting is intended to facilitate the automation and intelligent operation of the cooking appliance 100. During use, the operating speed can be increased according to the user's needs, and the operating power of each speed setting can be adjusted or defined manually.

[0069] In summary, please refer to the following: Figures 1-12 The cooking appliance 100 provided in this embodiment has the following advantages:

[0070] The refrigeration unit not only improves indoor temperature and prevents smoke escape, but also cools the smoke in the flue 122, accelerating the condensation of oil fumes. The fresh air unit 170 improves smoke collection and indoor ventilation, reducing the amount of smoke inhaled by users. It is versatile and adaptable, with exhaust vents 103 and heat outlets 102 on both sides to meet the installation requirements of most installation sites. The smoke inlet 104 and air outlet 101 are arranged side-by-side, facilitating smoke ventilation. The airflow of the supply air duct 132 and the exhaust air duct 132 do not interfere with each other; the supply air duct 132 and the exhaust air duct share the same wall surface, and the wall surface temperature is low in summer due to cooling, which accelerates the condensation of oil fumes; the wall surface temperature is high in winter due to lack of cooling, which increases the temperature of fresh air; the exhaust air pipe 125 and the heat exhaust pipe can be combined and discharged into the exhaust air duct 122, reducing the number of openings in the user's wall and reducing the difficulty of installation; the operating status of the range hood module 120, the cooling module 130 and the fresh air unit 170 can be determined and adjusted according to the indoor temperature, outdoor temperature and flue gas conditions, thereby improving the user experience.

[0071] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
