Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, and in particular to a cooking device and an integrated cooking equipment. Background Art

[0002] As people's requirements for quality of life become higher and higher, there are more and more types of cooking devices. Currently, there are cooking devices on the market that use steam to heat food, such as steamers and steam ovens. Moreover, this cooking device can be embedded in a cabinet or embedded in an integrated stove. It is convenient and efficient to use and is widely praised by consumers.

[0003] Embedded cooking devices have the advantages of high integration, small space occupation, and tidy kitchen, but they involve the problem of steam discharge. Most of the current embedded cooking devices use front exhaust, that is, an exhaust port is set on the front of the embedded cooking device, and the steam is discharged into the steam channel located at the top of the inner pot through the exhaust port on the top of the inner pot of the embedded cooking device. The air outlet of the steam channel is connected to the fan, and the air outlet is connected to the exhaust port on the front. The steam channel is fan-shaped with a gradually increasing cross-sectional area along the direction from the air inlet to the air outlet. The steam channel is formed by the cover covering the top wall of the inner pot and the top wall of the inner pot.

[0004] However, during use, condensed water will condense on the inner wall of the steam channel, and the condensed water cannot be recycled, so the steam discharge volume of the built-in cooking device is large. Users need to frequently add water to the water box. Moreover, the condensed water will increase the humidity in the cabinet, causing bacteria to grow. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, an embodiment of the utility model provides a cooking device, including: an exhaust pipe, which is connected to the outside; an inner pot, which is provided with an inner pot steam outlet; and a condensation assembly, which is arranged outside the inner pot, the condensation assembly includes a condensation pipe and a heat sink arranged on the outer surface of the condensation pipe, the inner pot steam outlet is connected to the steam inlet of the condensation pipe, and the steam outlet of the condensation pipe is connected to the exhaust pipe.

[0006] The water vapor with a higher temperature can be cooled in the condenser and condensed into condensed water. The heat sink can quickly transfer the heat in the condenser to the air, thereby maintaining a large temperature difference with the water vapor to ensure the heat exchange rate, quickly cool the water vapor, and thus reduce the amount of steam discharged. Moreover, the condensed water is retained in the exhaust pipe and the condenser, so the condensed water can flow back into the inner tank along the pipeline, thereby further reducing the amount of steam discharged. The outlet of the exhaust pipe can be connected to any suitable location, so that the steam can be discharged to any desired location, such as discharged into a sewer pipe, discharged into a range hood, discharged to the outdoors, and so on.

[0007] Exemplarily, the cooking device further comprises a heat dissipation fan arranged outside the inner pot, and an air outlet of the heat dissipation fan faces the heat sink.

[0008] The air outlet of the cooling fan can be directed toward the heat sink, so that a larger flow of air can pass through the heat sink quickly to achieve a better heat dissipation effect.

[0009] Exemplarily, the heat dissipation fan is arranged at the front of the inner pot, and the air outlet of the heat dissipation fan faces the rear of the cooking device.

[0010] By arranging the cooling fan at the front of the inner tank, the cooling fan can draw air from the front side of the inner tank, where the temperature is lower, which is more conducive to achieving a better cooling effect.

[0011] Exemplarily, the cooking device further includes an electric control board, which is located outside the inner pot and behind the heat dissipation fan, and the pipe section of the condenser tube provided with heat dissipation fins is located between the heat dissipation fan and the electric control board.

[0012] The electric control board is placed behind the cooling fan. The cooling fan can provide a certain degree of cooling to the electric control board while cooling the condenser. Placing the condenser closer to the air outlet of the cooling fan than the electric control board can give priority to cooling the condenser and improve the condensation effect.

[0013] Exemplarily, the heat sink is multiple and arranged in parallel to form multiple intervals arranged along the condenser tube between adjacent heat sinks, or the heat sink extends spirally and forms multiple intervals arranged along the condenser tube between adjacent threads, wherein the air outlet direction of the heat sink fan is perpendicular to the condenser tube.

[0014] The airflow of the cooling fan passes through these intervals, thereby increasing the contact area with the condenser tube for heat exchange and improving the cooling efficiency.

[0015] Exemplarily, the condensing assembly is disposed on the top wall of the inner container.

[0016] The cooking device thus configured has a smaller internal free space, thereby making the overall size of the cooking device more compact.

[0017] Exemplarily, the steam outlet of the inner tank is arranged at the lower part of the inner tank, the condenser includes a first condenser section and a second condenser section connected sequentially along the steam discharge direction, the first condenser section extends upward from the steam outlet of the inner tank, the second condenser section is located above the inner tank, and the heat sink is arranged on the second condenser section, wherein: the second condenser section is arranged to be inclined upward along the steam discharge direction.

[0018] When the steam condenses in the condenser, the condensed water can flow along the inclination angle of the pipe and flow back to the steam outlet of the inner tank from the nearly vertical first condenser section and enter the inner tank. In this way, no water will accumulate in the condenser, which can avoid noise caused by bubbles during operation and prevent bacteria from growing due to water accumulation when the condenser is idle.

[0019] Exemplarily, the second condensing pipe section includes a first sub-pipe section, a second sub-pipe section and a third sub-pipe section connected in sequence into a U shape, the opening of the U shape faces the rear of the cooking device, and the heat sink is arranged on the second sub-pipe section.

[0020] The above technical solution can be provided with a first sub-pipe section and a third sub-pipe section to form a U-shaped structure to avoid the heat dissipation fan. The heat dissipation fan can be provided in the U-shaped opening.

[0021] Exemplarily, there are a plurality of second sub-pipe sections, each of which is provided with a heat sink, and the plurality of second sub-pipe sections are connected in parallel between the first sub-pipe section and the third sub-pipe section.

[0022] A plurality of thinner second sub-pipe sections are connected in parallel between the first sub-pipe section and the third sub-pipe section, which can effectively improve the cooling effect while keeping the flow rate substantially unchanged.

[0023] Exemplarily, the angle between the second condensation pipe section and the horizontal plane is between 5 degrees and 10 degrees.

[0024] At this angle, the vertical space occupied by the second condensation pipe section will not be too large, and the flow effect of the condensed water is relatively good.

[0025] Exemplarily, the exhaust pipe is located at the upper rear of the inner tank.

[0026] It is placed at the back away from the user to avoid burns.

[0027] According to another aspect of the utility model, an integrated cooking device is provided, including a cooker and the above-mentioned cooking device, wherein the cooker is arranged above the cooking device, a steam exhaust port is arranged at the rear of a panel of the cooker, and a steam exhaust pipe is connected to the steam exhaust port.

[0028] When the cooking device is working, the residual steam after condensation by the condensation component can be discharged through the exhaust port, and can be discharged to the outside through the range hood (if any) above the integrated cooking device.

[0029] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

DETAILED DESCRIPTION

[0042] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0043] The embodiment of the utility model provides a cooking device. The cooking device can be embedded or non-embedded. The cooking device can be applied to integrated cooking equipment, such as an integrated stove, etc. The cooking device of the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0044] like Figure 1 As shown, the cooking device 10 may include an exhaust pipe 100 and an inner pot 200. The exhaust pipe 100 is located at the rear of the cooking device 10 and is connected to the outside. Taking the cooking device 10 as a steam oven, when the cooking device 10 is working, the heating component 600 arranged at the rear of the inner pot 200 heats the air in the inner pot 200, and at the same time, the steam generating device passes water into the inner pot 200 for evaporation. In addition, a circulating fan 700 is also arranged at the rear of the inner pot 200. The circulating fan 700 can circulate heat and water vapor in the inner pot 200 so as to evenly heat the food. For safety and aesthetics, a fan cover 710 is arranged in front of the circulating fan 700, see Figure 4-5 .

[0045] As the water vapor gradually increases during the heating process, the pressure in the inner pot 200 will also gradually increase. In order to avoid excessive pressure in the inner pot 200, the inner pot 200 may also be provided with an inner pot steam outlet 210. Excess water vapor and air in the inner pot 200 will be discharged from the inner pot steam outlet 210, for example, discharged into the air through the exhaust pipe 100. Due to the high temperature and humidity of the steam outlet, the indoor humidity may increase accordingly. The high temperature at the outlet of the exhaust pipe 100 may also cause burns. Therefore, the cooking device 10 may also include a condensation component, which may be arranged outside the inner pot 200. The condensation component may include a condensation pipe 310 and a heat sink 320 arranged on the outer surface of the condensation pipe 310, the inner pot steam outlet 210 may be connected to the steam inlet of the condensation pipe 310, and the steam outlet of the condensation pipe 310 may be connected to the exhaust pipe 100. The water vapor with a higher temperature can be cooled in the condensation pipe 310 and condensed into condensed water. The heat sink 320 can quickly transfer the heat in the condenser tube 310 to the air, thereby maintaining a large temperature difference with the water vapor to ensure the heat exchange rate, quickly cool the water vapor, and thus reduce the amount of steam discharged. In addition, the condensed water is retained in the exhaust pipe 100 and the condenser tube 310, so the condensed water can flow back to the inner tank 200 along the pipeline, thereby further reducing the amount of steam discharged. The outlet of the exhaust pipe 100 can be connected to any suitable location, so that the steam can be discharged to any desired location, such as discharged into a sewer pipe, discharged into a range hood, discharged to the outdoors, etc.

[0046] For example, the exhaust pipe 100 can be arranged at the rear of the cooking device 10. The user will not touch this place. Compared with the front exhaust method, the risk of the user contacting the water vapor can be greatly reduced.

[0047] For example, the heat sink 320 can transfer heat to the air, thereby rapidly reducing its own temperature. When the air velocity passing through the heat sink 320 increases, the heat of the heat sink 320 can be taken away more quickly, thus preventing heat from accumulating on the heat sink 320 and improving heat dissipation efficiency. Figure 1 As shown, the cooking device 10 may further include a heat dissipation fan 400 disposed outside the inner pot 200. The heat dissipation fan 400 may include one or more of an axial flow fan and a centrifugal fan, and may blow air in a fixed direction. The air outlet of the heat dissipation fan 400 may be directed toward the heat sink 320, so that a large flow of air quickly passes through the heat sink 320, thereby achieving a better heat dissipation effect. The air outlet of the heat dissipation fan 400 may be divergent, so the distance between the air outlet of the heat dissipation fan 400 and the heat sink 320 may be appropriately shortened, thereby further improving the heat dissipation effect.

[0048] Exemplarily, the heat dissipation fan 400 may be located at the front of the inner pot 200. The air outlet of the heat dissipation fan 400 may face the rear of the cooking device 10. As mentioned above, the heating assembly 600 may be provided at the rear of the inner pot 200, and the cooking device 10 will be embedded in a cabinet or an integrated stove as a whole when in use, and the temperature at the rear is higher. By arranging the heat dissipation fan 400 at the front of the inner pot 200, the heat dissipation fan 400 can draw air from the front side of the inner pot 200, where the temperature is lower, which is more conducive to achieving a better heat dissipation effect.

[0049] For example, Figure 3 As shown, the cooking device 10 may further include an electric control board 500, which is at least used to control the operation of the cooking device 10. For example, the electric control board 500 may be electrically connected to the circulating fan 700, the heating component 600, etc., and detect and control the heating power of the heating component 600, the wind force of the circulating fan 700, etc. through a temperature probe (not shown), so as to achieve a better heating effect on the food in the inner pot 200. The electric control board 500 may also be used for timing and other tasks, which are not listed here. The electric control board 500 may be constructed using electronic components such as timers, comparators, registers, digital logic circuits, or may be implemented using processor chips such as single-chip microcomputers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic arrays (PLA), application specific integrated circuits (ASICs), and their peripheral circuits.

[0050] The electric control board 500 can be located outside the inner tank 200 and behind the heat dissipation fan 400. It is understood that the electric control board 500 will also generate heat when working. By arranging the electric control board 500 behind the heat dissipation fan 400, the heat dissipation fan 400 can provide a certain degree of cooling to the electric control board 500 while cooling the condenser 310. Figure 3 In the specific embodiment shown, the pipe section of the condenser 310 provided with the heat sink 320 can be located between the heat dissipation fan 400 and the electric control board 500. Since the temperature of the condenser 310 must be low enough to reduce the amount of steam discharged. As mentioned above, the wind force of the heat dissipation fan 400 may be divergent. Therefore, by making the condenser 310 closer to the air outlet of the heat dissipation fan 400 than the electric control board 500, the condenser 310 can be cooled preferentially to improve the condensation effect. Moreover, the heat generation of the condenser 310 is much greater than that of the electric control board 500. A smaller air volume can be provided to cool the electric control board 500 to meet its working temperature, while a larger air volume is required to meet its working temperature.

[0051] For example, the heat sink 320 may be multiple and arranged in parallel, so that a plurality of intervals arranged along the condenser tube 310 are formed between adjacent heat sink 320. Figure 2a-2cAs shown, the heat sink 320 may include a plurality of independent fins 321, and the fins 321 may be in various shapes such as circular and triangular, and the surface may be flat, or uneven or wavy. In short, these fins 321 may be welded, plugged or sleeved on the condenser tube 310, forming a plurality of intervals with equal or unequal distances arranged along the condenser tube 310. The air outlet direction of the heat dissipation fan 400 may be perpendicular to the condenser tube 310. When the heat dissipation fan 400 is working, the air flow generated may pass through the intervals between the fins 321, thereby increasing the contact area between the condenser tube 310 and the air, and enhancing the heat dissipation. Exemplarily, the fins 321 may be made of a heat-conducting material, such as a metal material, so as to conduct the heat quickly. The heat transfer between the fins 321 and the condenser tube 310 should also be good.

[0052] The heat sink 320 can be formed perpendicularly to the condenser tube 310, and the airflow of the heat dissipation fan 400 can also be perpendicular to the condenser tube 310, so as to pass through the gap. The heat sink 320 can also extend in the same direction as the condenser tube 310, and the airflow direction of the heat dissipation fan 400 is in the same direction as the condenser tube 310.

[0053] Not shown, the heat sink may also be spirally extended and form a plurality of intervals arranged along the condenser tube between adjacent threads, and the air outlet direction of the heat dissipation fan is also perpendicular to the condenser tube. For example, the condenser tube may include a spiral fin tube, and the spiral fin tube may be made of standard parts, with good heat dissipation effect and low cost. Intervals may also be formed between adjacent threads of the fins, and the airflow of the heat dissipation fan passes through these intervals, thereby increasing the contact area of ​​heat exchange with the condenser tube and improving the heat dissipation efficiency.

[0054] For example, continue to refer to Figure 3 The cooking device 10 can be set in an integrated stove or a cabinet, and the height is usually very low. A water box (not shown) for adding water to the inner pot 200 of the cooking device 10 is usually set at the upper part of the cooking device 10, so that the user does not need to bend down to operate when adding water, and the user experience is better. In order to hold enough water, the water box usually has a certain thickness, but in order to avoid the water box getting stuck when being pulled out of the cooking device 10, its width is generally not large.

[0055] Therefore, there is a large free area above the top wall of the inner pot 200 in the upper part of the cooking device 10. The condensing assembly can be arranged on the top wall of the inner pot 200, which can effectively improve the space utilization of the cooking device 10. Of course, the cooling fan and the electric control board 500 can also be arranged on the top wall of the inner pot 200. The free space inside the cooking device 10 arranged in this way is small, so that the overall size of the cooking device 10 can be made more compact.

[0056] Exemplarily, the inner liner steam outlet 210 may be disposed at the lower portion of the inner liner 200. The lower portion of the inner liner 200 includes the lower portion of the side wall of the inner liner 200 and the bottom of the inner liner 200. In the illustrated embodiment, the inner liner steam outlet 210 is disposed at the lower portion of the side wall of the inner liner 200. The inner liner steam outlet 210 can not only discharge water vapor from the inner liner 200, but also return part of the liquid water condensed in the condensation assembly to the inner liner 200, thereby replenishing the water in the inner liner 200. Figure 5 As shown, the side wall of the inner liner 200 may be provided with a protrusion 220 for setting up a food tray, and the rear wall of the inner liner 200 is provided with a perforated plate 230 for the flow of heated air. Taking the inner liner steam outlet 210 set on the rear wall of the inner liner 200 as an example, the inner liner steam outlet 210 can be set at a position avoiding the airflow of the circulating fan 700. If it is set at the upper part of the inner liner 200, the flow path of the condensed water is difficult to avoid the airflow of the circulating fan 700. When the condensed water flows back to the inner liner 200, it may be blown onto the food due to the wind force of the circulating fan 700 during the downward flow process, thereby affecting the appearance and taste of the food. The inner liner steam outlet 210 is set at the lower part of the inner liner 200. On the one hand, the condensed water only needs to flow a short distance on the inner liner wall to return to the water storage tray at the bottom of the inner liner 200, so that it evaporates again and participates in the heating of the food. On the other hand, the condensed water evaporates into water vapor at the bottom of the inner pot 200, which can pass through and transfer heat to the food, rather than evaporating into water vapor at a higher position of the inner pot 200 without passing through the food, causing heat waste.

[0057] The condenser 310 may include a first condenser section 311 and a second condenser section 312 connected in sequence along the steam discharge direction, the first condenser section 311 extends upward from the inner tank steam outlet 210, the second condenser section 312 may be located above the inner tank 200, and the heat sink 320 is arranged on the second condenser section 312. As described above, the space above the inner tank 200 is relatively sufficient, so the second condenser section 312 may be arranged above the inner tank 200, and the first condenser section 311 may only be used to connect the inner tank steam outlet 210 to the second condenser section 312, and will not occupy a large space. The first condenser section 311 and the second condenser section 312 may be hard pipes, connected at the bend by joints or welding, or may be directly bent by an integrated pipe. The first condenser section 311 and the second condenser section 312 may also be soft pipes, which are easier to bend at the bend. The second condenser section 312 may be arranged to be tilted upward along the steam discharge direction. When steam condenses in the condenser tube 310, the condensed water can flow along the inclination angle of the pipe and flow back to the inner tank steam outlet 210 from the nearly vertical first condenser tube section 311 to enter the inner tank 200. In this way, no water will accumulate in the condenser tube 310, which can avoid noise caused by bubbles during operation and prevent bacteria from growing due to water accumulation when idle.

[0058] For example, the angle between the second condensing pipe section 312 and the horizontal plane is between 5 degrees and 10 degrees. At this angle, the vertical space occupied by the second condensing pipe section 312 is not too large, and the flow effect of the condensed water is relatively good. For different cooking devices 10, this angle can also be appropriately adjusted according to actual needs.

[0059] For example, Figure 2a-2c As shown, the second condensing pipe section 312 may include a first sub-pipe section 3121, a second sub-pipe section 3122, and a third sub-pipe section 3123 that are sequentially connected to form a U shape. The opening of the U shape faces the rear of the cooking device 10, and the heat sink 320 is disposed on the second sub-pipe section 3122. The first bracket 331 and the second bracket 332 may be disposed on the top wall of the inner pot 200 to support the second sub-pipe section 3122. The heights of the first bracket 331 and the second bracket 332 may be the same or different. Figure 2a , when the heights of the first bracket 331 and the second bracket 332 are different, the steam inlet end of the second sub-pipe section 3122 is lower than the steam outlet end. As described above, the closer the heat sink 320 is to the air outlet of the heat dissipation fan 400, the greater the wind speed passing through the heat sink 320, and the less likely heat is to accumulate. Figure 1 In the illustrated embodiment, the heat dissipation fan 400 is disposed at the front of the cooking device 10, and the air outlet of the heat dissipation fan 400 faces the rear of the cooking device 10. When the inner pot steam outlet 210 is disposed on the rear wall of the inner pot 200, the connection between the first condensation pipe section 311 and the second condensation pipe section 312 may also be at the rear of the cooking device 10. Therefore, the second sub-pipe section 3122 may be disposed adjacent to the heat dissipation fan 400, the first sub-pipe section 3121 extends from the rear of the cooking device 10 to the front of the cooking device 10, and is connected between the first condensation pipe section 311 and the second sub-pipe section 3122; the third sub-pipe section 3123 extends from the front of the cooking device 10 to the rear of the cooking device 10, and is connected between the second sub-pipe section 3122 and the exhaust pipe 100 located at the rear, thereby forming a U-shaped structure.

[0060] In an embodiment not shown, the heat dissipation fan may also be arranged at the rear of the cooking device, with the air outlet of the heat dissipation fan facing the front of the cooking device. If the first sub-pipe section and the third sub-pipe section are not arranged, and the second sub-pipe section directly extends from the first condensation pipe section to the exhaust pipe, it is difficult to leave enough space between the rear wall of the cooking device and the second sub-pipe section to accommodate the heat dissipation fan. Therefore, the first sub-pipe section and the third sub-pipe section may also be arranged to form a U-shaped structure to avoid the heat dissipation fan. The heat dissipation fan may be arranged in the U-shaped opening.

[0061] In the above embodiment, on the one hand, the second sub-pipe section 3122 provided with the heat sink 320 in the second condensing pipe section 312 can be close to the heat dissipation fan 400 to improve the heat dissipation efficiency. On the other hand, the longer condensing pipe 310 can also prolong the residence time of the steam, thereby enhancing the condensation effect to a certain extent.

[0062] like Figure 2d As shown, illustratively, there are multiple second sub-pipe sections 3122, and each second sub-pipe section 3122 can be provided with a heat sink 320. The second sub-pipe section 3122 can select a thicker pipe or a thinner pipe. When the steam passes through the thicker pipe, the water vapor in contact with the inner wall of the pipe on the outside is cooled and condensed, while the cooling effect of the water vapor on the inside is poor. In contrast, the cooling effect of the thinner pipe is better, but the steam flow rate is smaller. Multiple thinner second sub-pipe sections 3122 are connected in parallel between the first sub-pipe section 3121 and the third sub-pipe section 3123, which can effectively improve the cooling effect while the flow rate remains substantially unchanged. The second sub-pipe section 3122 should not be too thin to prevent the condensed water from blocking the second sub-pipe section 3122 and preventing it from flowing back.

[0063] According to another aspect of the present invention, Figure 6 As shown, an integrated cooking device 20 is also provided, and the above-mentioned cooking device 10 can be arranged in the integrated cooking device 20. The integrated cooking device 20 can also include a stove 22, and the stove 22 can be arranged above the cooking device 10. A steam exhaust port 21 is arranged at the rear of the panel of the stove 22, and the steam exhaust pipe 100 can be connected to the steam exhaust port 21. The steam exhaust port 21 is farther away from the user than the stove 22, so the user usually does not touch the steam exhaust port 21, and will not be scalded. When the cooking device 10 is working, the residual steam after condensation by the condensation component can be discharged through the steam exhaust port 21, and can be discharged to the outside through the range hood (if any) above the integrated cooking device 20. In short, the steam exhaust port 21 is arranged on the panel of the stove 22, which can avoid the adverse effects caused by the residual steam, and is arranged at the rear away from the user, which can avoid the user from being scalded.

[0064] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front", "back", "up", "down", "left", "right", "lateral", "vertical", "vertical", "horizontal", "top", "bottom", etc. are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description.
