Description

Technical Field

[0001] The present disclosure relates to the technical field of cooking appliances, and particularly to a steam baking appliance. Background Art

[0002] With the development of cooking appliance technology, cooking appliances with a steaming function such as steam ovens are popular among health enthusiasts. Cooking appliances with a steaming function can utilize the dynamic steam balance technology to retain the original nutrients of food, which in turn has promoted the emergence of steam baking integrated machines. Since the functions of a steam oven and an oven are integrated into one, the steam baking integrated machine effectively reduces the occupation of kitchen space by independent steam ovens and ovens, and is deeply loved by consumers.

[0003] During the cooking process of existing cooking appliances with a steaming function such as steam baking integrated machines, the amount of externally discharged steam is large, resulting in a relatively high temperature of the externally discharged steam. The temperature of the externally discharged steam has always attracted people's attention. A high temperature is not only likely to cause discomfort to the human body, but may even burn the human skin. Therefore, it is particularly important to have a relatively low externally discharged steam and its temperature. At the same time, the reduction of steam in the inner cavity leads to a reduction in the steaming function time. Summary of the Utility Model

[0004] Based on this, in view of the above problems, it is necessary to provide a steam baking appliance.

[0005] An embodiment of the present disclosure provides a steam baking appliance, which includes an inner cavity, a steam generator, a heat dissipation device, and a condensation device; the inner cavity has a cooking chamber and an exhaust duct communicating with the cooking chamber; the steam generator is disposed in the cooking chamber and at the bottom of the inner cavity; the heat dissipation device is disposed on the outer wall of the inner cavity, and the heat dissipation device has a cold air chamber; the condensation device includes a water supply component and a condenser, the condenser has a condensation chamber, the condenser is disposed on the wall of the cold air chamber, and the condensation chamber communicates with the cold air chamber; a cooling pipeline is provided on the side wall or the top wall of the condenser, and the two ends of the cooling pipeline are respectively communicated with the water supply component and the condensation chamber; the condensation chamber communicates with the cooking chamber through the exhaust duct.

[0006] The steam cooking device provided by the embodiments of the present disclosure has a water-cooled cooling pipeline at the top of the condenser. The water from the water supply component sequentially enters the inner container through the cooling pipeline, the condensation chamber and the exhaust pipeline. The cooling pipeline can quickly reduce the temperature of the top wall and the side wall of the condenser. When high-temperature steam contacts the top wall, part of the high-temperature steam condenses into water and then returns to the steam generator through the exhaust pipeline, taking away the heat of the condensation chamber and being reused, improving the steam condensation and reflux effect, saving energy and increasing the working time of the steaming function at the same time. At the same time, the bottom of the condenser is an air-cooled heat dissipation device. The high-temperature steam is located between the heat dissipation device and the cooling pipeline, making it easier to reduce the temperature and condense. The dual cooling of air-cooling and water-cooling improves the steam condensation and temperature reduction efficiency and effect, facilitating the external discharge of steam through the cold air chamber and thus improving the user's comfort. In addition, the water supply component directly supplies water to the steam generator through the cooling pipeline, the condensation chamber and the exhaust pipeline. The pipeline connection is simple. While the steam temperature decreases, the water temperature entering the inner container rises, saving energy, reducing the heating time and prolonging the working time of the steaming function.

[0007] In some embodiments, the cooling pipeline includes a plurality of straight sections and a plurality of bent sections. The plurality of straight sections are arranged in parallel, and both ends of the straight section are respectively connected to a bent section.

[0008] With such an arrangement, the arrangement of the plurality of straight sections and the bent sections increases the contact area between the water flow and the top wall or the side wall of the condenser, which is beneficial to reducing the overall temperature of the condenser, facilitating increasing the condensation effect and reducing the temperature of the high-temperature steam.

[0009] In some embodiments, the condenser is provided with an air inlet, the air inlet is communicated with the exhaust pipeline, the bottom wall of the condenser is inclined downward towards the air inlet, and the air inlet is located at the lowest position of the bottom wall of the condenser.

[0010] With such an arrangement, the bottom wall of the condenser is inclined and installed, and the air inlet is located at the lowest position of the bottom wall, which is convenient for the high-temperature steam to enter the condensation chamber upward and helps the water formed after the condensation of the high-temperature steam to flow back to the inner container to form steam for secondary utilization.

[0011] In some embodiments, the cooling pipeline is fittingly arranged on the top wall of the condenser, and the end of the cooling pipeline communicated with the condensation chamber and the air inlet are located on the same side of the condenser.

[0012] With such an arrangement, the top wall of the condenser can be kept at a low temperature, which is convenient for the continuous temperature reduction of the high-temperature steam that is easy to contact the top wall. The same-side arrangement enables the water flow to conveniently flow into the air inlet after flowing out of the cooling pipeline and into the condensation chamber.

[0013] In some embodiments, the condenser is provided with at least one exhaust hole, and the exhaust hole is communicated with the cold air chamber; the exhaust hole is located at the highest position of the bottom wall of the condenser, and the upper surface of the bottom wall of the condenser connected to the exhaust hole is convexly provided with a flanging.

[0014] This arrangement prolongs the flow time of high-temperature steam in the condensation chamber, and the high exhaust holes facilitate the steam to enter the cold air chamber and then be discharged after cooling. The flange setting can prevent water from bypassing the exhaust holes and prevent water from flowing into the cold air chamber.

[0015] In some of the embodiments, the heat dissipation device includes a heat dissipation fan and an air guide plate. The air guide plate and the outer wall of the inner tank are combined to form a cold air cavity. The heat dissipation fan is connected to the cold air cavity, and the bottom wall of the condenser is in contact with the air guide plate.

[0016] With this arrangement, the heat dissipation fan can continuously provide cold air to the cold air chamber. The cold air chamber can cool down the high-temperature steam in the lower cavity by air cooling, while also dissipating heat to the inside of the inner pot, thereby reducing the overall temperature of the steaming and baking equipment.

[0017] In some of the embodiments, the bottom wall of the condenser fits the outer wall of the cold air chamber; the air guide plate is provided with an opening, and the outer wall of the condenser is adapted to the opening.

[0018] Such arrangement enables the bottom wall of the condenser to directly contact the flowing cooling airflow through the opening, thereby accelerating the speed of heat transfer and exchange. The flowing cooling airflow takes away more heat from the bottom wall of the condenser, increasing the effect of steam condensation reflux.

[0019] In some of the embodiments, an air inlet and at least one air outlet are provided on the air guide plate, the air inlet and the air outlet are located on both sides of the condenser, the air inlet is opened upward, and the heat dissipation fan is installed at the air inlet.

[0020] With this arrangement, the air inlet at the top facilitates the entry of cooling airflow, improving the smoothness of the cooling airflow in the condensing chamber, thereby fully dissipating the heat from the bottom of the condenser, taking away the cooled steam and eventually discharging it from the air outlet of the air guide plate, increasing the heat dissipation effect of air cooling.

[0021] In some of the embodiments, the condensing device further comprises a plurality of heat sinks, which are protruding from the bottom wall of the condenser, are located in the cold air cavity, and extend along the air inlet toward the air outlet.

[0022] With this arrangement, the heat sink can not only guide the cooling airflow, but also increase the contact area between the cooling airflow and the condensing device, thereby reducing the temperature of the bottom wall of the condenser and further improving the cooling and condensing effect of the condenser on high-temperature steam.

[0023] In some of the embodiments, the water supply assembly is disposed on the outer wall of the inner tank, and the water supply assembly includes a water tank, a water inlet pipe and a control valve. The water inlet pipe connects the water tank with the condensation chamber; the control valve is installed on the water inlet pipe.

[0024] With such a setting, the water volume can be controlled in real time through the control valve, ensuring sufficient water consumption of the steam generator, continuous water flow in the condensation chamber and no water flowing out from the exhaust holes, thereby ensuring the condensation effect on the high-temperature steam in the condensation chamber.

[0038] Refer to Figure 1 , Figure 1FIG. 0 shows the overall structure of the steam cooking device 100 according to an embodiment of the present disclosure. The present disclosure relates to the technical field of cooking devices. The steam cooking device 100 of the present disclosure may be a steam oven, an oven, or a steam oven and grill integrated machine, etc., which is a cooking device that uses dynamic steam balance technology to retain the original nutritional components of food.

[0039] Referring Figure 2 to Figure 3 and

[0040] An embodiment of the present disclosure provides a steam cooking device 100, which includes an inner container 1, a steam generator 4, a condensation device 2, and a heat dissipation device 3. The inner container 1 has a cooking cavity 11, and the steam generator 4 is disposed in the cooking cavity 11 and at the bottom of the inner container 1; the inner container 1 also has an exhaust duct 12 communicating with the cooking cavity 11. Exemplarily, there is a baking tray for placing food in the cooking cavity 11, and the baking tray is filled with food and placed above the steam generator 4. The steam generator 4 is used to continuously generate high-temperature steam to heat the food until it is cooked; the exhaust duct 12 discharges the high-temperature steam generated by cooking through an air port. The heat dissipation device 3 is disposed on the outer wall of the inner container 1; the heat dissipation device 3 has a cold air cavity 31. Exemplarily, the heat dissipation device 3 is disposed above the inner container 1, and there is a flowing cooling air flow in the cold air cavity 31. The condensation device 2 includes a water supply component 22 and a condenser 21. The condenser 21 has a condensation cavity 211. The condenser 21 is disposed on the wall of the cold air cavity 31, and the condensation cavity 211 communicates with the cold air cavity 31; a cooling pipeline 212 is provided on the side wall or the top wall of the condenser 21, and both ends of the cooling pipeline 212 are respectively communicated with the water supply component 22 and the condensation cavity 211; the condensation cavity 211 communicates with the cooking cavity 11 through the exhaust duct 12. Exemplarily, the condenser 21 is disposed above the heat dissipation device 3, and the water of the water supply component 22 flows in the cooling pipeline 212 and then enters the condensation cavity 211 and enters the inner container 1 through the exhaust duct 12 to provide the required water volume for the steam generator 4. Exemplarily, the high-temperature steam enters the condensation cavity 211 through the exhaust duct 12, and after cooling down in the condensation cavity 211, the steam is discharged through the cold air cavity 31.

[0041] In addition, the steam generator 4 is located at the bottom of the inner container 1. The inner container 1 is communicated with the condensation chamber 211 through an exhaust pipe 12, and the condensation chamber 211 is communicated with the water supply assembly 22 through a cooling pipeline 212. Thus, the water of the water supply assembly 22 can enter the inner container 1 through the cooling pipeline 212, the condensation chamber 211 and the exhaust pipe 12. The air port of the exhaust pipe 12 is located above the steam generator 4. While the steam temperature decreases, the water temperature of the water entering the inner container 1 rises. After the water enters the inner container 1, it drips from above or gradually converges to the upper surface of the steam generator 4, and can quickly turn into steam in the steam generator 4 to continue heating food, saving energy and reducing the heating time; there is no need to separately arrange a pipeline to supply water to the steam generator 4, and the water supply pipeline is less and the connection is simple.

[0042] Exemplarily, the steam generator 4 is located in the central area at the bottom of the inner container 1. The air port of the exhaust pipe 12 located in the cooking chamber 11 is located above the steam generator 4, and the steam generator 4 is located at the lowest position of the inner container 1, so that the water at the bottom of the inner container 1 can converge to the upper surface of the steam generator 4 from all around. Since the temperature of the upper surface of the steam generator 4 is relatively high, the water can be quickly heated to form high-temperature steam and move upward to steam-bake food.

[0043] Exemplarily, the inner container 1 is square in shape, and both the condensation device 2 and the heat dissipation device 3 are located on the upper surface of the inner container 1. From bottom to top, they are the inner container 1, the heat dissipation device 3 and the condensation device 2 in sequence.

[0044] Exemplarily, the heat dissipation device 3 is irregular in shape. The condenser 21 is also irregular in shape. The irregular shape can extend the residence time of the cooling air flow and the high-temperature steam, and increase the heat dissipation effect of air cooling and liquid cooling.

[0045] Exemplarily, the material of the condenser 21 is a metal material or an alloy material. Since the metal material has good thermal conductivity and the heat transfer is rapid, it can improve the heat dissipation effect of dual cooling of water cooling and air cooling. Exemplarily, the material of the condenser 21 is aluminum alloy. In other embodiments, the material of the condenser 21 can also be stainless steel or other materials with good thermal conductivity.

[0046] Reference Figures 1 to 4 , in some of the embodiments, the cooling pipeline 212 includes a plurality of straight sections 2121 and a plurality of bent sections 2122. The plurality of straight sections 2121 are arranged in parallel, and both ends of the straight section 2121 are respectively connected to a bent section 2122. With such an arrangement, the setting of the plurality of straight sections 2121 and the bent sections 2122 increases the contact area between the water flow and the top wall or the side wall of the condenser 21, which is beneficial to reducing the overall temperature of the condenser 21, facilitating increasing the condensation effect, and reducing the temperature of the high-temperature steam.

[0047] Exemplarily, a cooling pipeline 212 is provided on the top wall of the condenser 21. The cooling pipeline 212 includes five straight sections 2121 and a plurality of bent sections 2122 connected thereto. The straight sections 2121 are arranged at intervals along the flowing direction of the cooling air flow. One end of the cooling pipeline 212 connected to the water supply assembly 22 extends out of the side wall and the top wall of the condenser 21. In other embodiments, the number of the straight sections 2121 and the bent sections 2122 included in the cooling pipeline 212 is not limited. The plurality of straight sections 2121 may also be arranged obliquely and crosswise.

[0048] Exemplarily, the cross-sectional shape of the cooling pipeline 212 is cylindrical. In other embodiments, the cross-sectional shape of the cooling pipeline 212 may also be square, rhombic, triangular or other irregular shapes.

[0049] Exemplarily, the upper surface of the cooling pipeline 212 protrudes from the upper surface of the top wall of the condenser 21, and the lower surface of the cooling pipeline 212 protrudes from the lower surface of the top wall of the condenser 21. In other embodiments, the cross-section of the cooling pipeline 212 may be smaller than the wall thickness of the top wall or the side wall of the condenser 21.

[0050] Reference Figure 4 , in some of these embodiments, the condenser 21 is provided with an air inlet 213. The air inlet 213 communicates with the exhaust pipeline 12. The bottom wall of the condenser 21 is inclined downwardly towards the air inlet 213, and the air inlet 213 is located at the lowest point of the bottom wall of the condenser 21. With such a setting, the bottom wall of the condenser 21 is inclinedly installed and the air inlet 213 is located at the lowest point of the bottom wall, which is convenient for the high-temperature steam to enter the condensation chamber 211 upwards and helps the water formed after the condensation of the high-temperature steam to flow back into the inner tank 1 to form steam for secondary utilization; it is also convenient for the water provided by the water supply assembly 22 to flow into the inner tank 1 and take away the heat in the condensation chamber 211.

[0051] Reference Figure 4 , in some of these embodiments, the cooling pipeline 212 is fittingly arranged on the top wall of the condenser 21. One end of the cooling pipeline 212 communicating with the condensation chamber 211 is on the same side as the air inlet 213 of the condenser 21. With such a setting, the top wall of the condenser 21 can be kept at a low temperature, which is convenient for the high-temperature steam that is easy to contact the top wall to continuously cool down. The same-side setting enables the water flow to conveniently flow into the air inlet 213 after flowing out of the cooling pipeline 212 and into the condensation chamber 211.

[0052] Exemplarily, one end of the cooling pipeline 212 communicating with the condensation chamber 211 is provided with a water outlet, and the water outlet faces the condensation chamber.

[0053] Exemplarily, the condenser 21 is inclined such that one end where the air inlet 213 is located is the lowest end of the condenser 21. The water provided by the water supply assembly 22 flows into the condensation chamber 211 through the cooling pipeline 212. The water flow flows along the inclined direction on the bottom wall of the condenser 21 to the lowest point and flows into the inner container 1 through the air inlet 213 and the exhaust pipeline 12. It can be understood that the inclination angle is determined according to actual needs. In other embodiments, the bottom wall of the condenser 21 can also be horizontally arranged.

[0054] Exemplarily, the connection between the air inlet 213 and the bottom wall of the condenser 21 is a slope, which facilitates the water flow.

[0055] Reference Figure 4 , in some embodiments, the condenser 21 is provided with at least one exhaust hole 214, and the exhaust hole 214 communicates with the cold air chamber 31; the exhaust hole 214 is located at the highest point of the bottom wall of the condenser 21, and the upper surface of the bottom wall of the condenser 21 connected to the exhaust hole 214 is convexly provided with a flange 215. With such a setting, the flow time of the high-temperature steam in the condensation chamber 211 is prolonged, and the exhaust hole 214 at a high position facilitates the cooled steam to enter the cold air chamber 31 and then be discharged. The setting of the flange 215 can block the water flow from flowing around the exhaust hole 214 and prevent the water from flowing into the cold air chamber 31 through the exhaust hole 214.

[0056] Exemplarily, three exhaust holes 214 are formed in the bottom wall of the condenser 21, and the three exhaust holes 214 are all arranged at the highest point of the bottom wall of the condenser 21. In other embodiments, the number of the exhaust holes 214 can also be two, four or more. Exemplarily, the sizes of the exhaust holes 214 are all different. In other embodiments, some of the sizes of the exhaust holes 214 can be the same or the sizes of all the exhaust holes 214 are the same.

[0057] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 , in some embodiments, the heat dissipation device 3 includes a heat dissipation fan 32 and a wind guide plate 33. The wind guide plate 33 and the outer wall of the inner container 1 enclose to form a cold air chamber 31. The heat dissipation fan 32 communicates with the cold air chamber 31, and the bottom wall of the condenser 21 is attached to the wind guide plate 33. With such a setting, the heat dissipation fan 32 can continuously supply cold air to the cold air chamber 31. While the cold air chamber 31 cools the high-temperature steam in the lower cavity by air cooling, it can also dissipate heat from the inside of the inner container 1 and reduce the overall temperature of the steaming and baking device 100.

[0058] Exemplarily, the air deflector 33 and the upper surface of the inner tank 1 enclose a cold air cavity 31. The side of the air deflector 33 where the heat dissipation fan 32 is located is the rear. The condenser 21 is located in the middle of the air deflector 33 and the area of the middle part of the air deflector 33 covering the inner tank 1 is the smallest. The area of the front part of the air deflector 33 covering the inner tank 1 is larger than the area of the rear side of the air deflector 33 covering the inner tank 1. With such a setting, when the cooling air flow enters from the rear and passes through the middle part, the flow velocity is relatively fast and the temperature is relatively low, and the cooling effect on the high-temperature steam in the condenser 21 is remarkable. When the cooling air flow enters the front part of the air deflector 33, the contact area with the inner tank 1 increases, the flow velocity of the cooling air flow slows down, and part of the heat outside the inner tank 1 can be taken away.

[0059] Reference Figures 1 to 3 , in some of the embodiments, the bottom wall of the condenser 21 is attached to the outer wall of the cold air cavity 31; an opening 331 is formed in the air deflector 33, and the outer wall of the condenser 21 is adapted to the opening 331. With such a setting, the bottom wall of the condenser 21 can directly contact the flowing cooling air flow through the opening 331, which speeds up the heat transfer and exchange speed. The flowing cooling air flow takes away more heat from the bottom wall of the condenser 21, and the effect of steam condensation and reflux is increased.

[0060] Exemplarily, the shape of the opening 331 is the same as the shape of the bottom wall of the condenser 21, and the size of the opening 331 is the same as the size of the bottom wall of the condenser 21. In other embodiments, the shape of the opening 331 is the same as the shape of the bottom wall of the condenser 21, and the lower half of the condensation cavity 211 can be accommodated inside the cold air cavity 31, so that both the side wall and the bottom wall of the condenser 21 can contact the flowing cooling air flow.

[0061] Exemplarily, the opening 331 can be square, circular, diamond-shaped or other irregular shapes.

[0062] In other embodiments, the middle part of the condenser 21 is located in the opening 331 of the air deflector 33. Or the part of the condenser 21 where the air outlet is provided is located in the opening 331 of the air deflector 33. In other embodiments, part of the cavity of the condenser 21 can be located inside the cold air cavity 31 through the opening 331, so that part of the side wall and part of the bottom wall of the condensation cavity 211 can both contact the flowing cooling air flow.

[0063] In some of the embodiments, an air inlet 332 and at least one air outlet 333 are formed in the air deflector 33. The air inlet 332 and the air outlet 333 are located on both sides of the condenser 21. The air inlet 332 is opened upward, and the heat dissipation fan 32 is installed in the air inlet 332. With such a setting, the air inlet 332 at the top facilitates the entry of the cooling air flow, improves the smoothness of the cooling air flow in the condensation cavity 211, thereby sufficiently dissipating heat from the bottom of the condenser 21, and the cooled steam is finally discharged from the air outlet 333 of the air deflector 33, increasing the air-cooled heat dissipation effect.

[0064] Exemplarily, the shape and size of the air inlet 332 are adapted to the cooling fan 32. The air inlet 332 is circular. The air inlet 332 is located at the rear of the heat conducting plate.

[0065] Exemplarily, there are multiple air outlets 333, and the air outlets 333 are located at the front of the heat conducting plate. The air outlets 333 are arranged in the front-back direction, facilitating the cooling air flow to flow from the rear to the front to dissipate heat from the inner tank 1 and the condenser 21.

[0066] Reference Figure 2 and Figure 5 In some embodiments, the condensing device 2 further includes a plurality of heat dissipating members 23. The heat dissipating members 23 protrude from the bottom wall of the condenser 21. The heat dissipating members 23 are located in the cold air chamber 31 and extend in the direction from the air inlet 332 towards the air outlet 333. With such an arrangement, the heat dissipating fins can not only guide the cooling air flow but also increase the contact area between the cooling air flow and the condensing device 2, reduce the temperature of the bottom wall of the condenser 21, and further improve the cooling and condensing effect of the condenser 21 on the high-temperature steam.

[0067] Exemplarily, the bottom wall of the condenser 21 is a flat surface, and the heat dissipating members 23 are heat dissipating fins. There are three heat dissipating fins, and the three heat dissipating fins are arranged at intervals parallel to the cooling air flow direction to form an air flow channel. The height of each heat dissipating fin is the same and is less than the height of the condensing chamber 211. In other embodiments, the number of heat dissipating fins is not limited. The heights of the heat dissipating fins can also be different.

[0068] Reference Figure 1 and Figure 3 In some embodiments, the water supply assembly 22 is provided on the outer wall of the inner tank 1. The water supply assembly 22 includes a water tank 221, a water inlet pipe 222, and a control valve 223. The water inlet pipe 222 communicates the water tank 221 with the condensing chamber 211; the control valve 223 is installed on the water inlet pipe 222. With such an arrangement, the water volume can be controlled in real time through the control valve 223 to ensure sufficient water consumption of the steam generator 4, continuous water flow in the condensing chamber 211, and no water flowing out from the exhaust hole 214, thereby ensuring the condensing effect on the high-temperature steam in the condensing chamber 211.

[0069] Exemplarily, the water tank 221 is arranged on the upper surface of the inner tank 1. One end of the water inlet pipe 222 communicating with the water tank 221 is higher than one end of the water inlet pipe 222 communicating with the cooling pipeline 212, and the control valve 223 is located in the middle part of the water inlet pipe 222.

[0070] Exemplarily, when using the steaming and baking device 100, if the steam generator 4 requires a large amount of water, the control valve 223 is opened, and the water in the water tank 221 flows into the condenser 21 through the water inlet pipe 222, the cooling pipeline 212, and the condensation chamber 211, and then enters the inner tank 1 through the exhaust pipeline 12 to supply water to the steam generator 4. At this time, the water flow rate in the cooling pipeline 212 is relatively fast; when the water volume in the inner tank 1 starts to increase, the control valve 223 adjusts the water volume and flow rate passing through the water inlet pipe 222 to slow down the water flow speed in the cooling pipeline 212, and so on in a cycle.

[0071] Reference Figures 1 to 3 , the steaming and baking device 100 provided by the embodiment of the present disclosure further includes a housing 5, and the inner tank 1, the condensation device 2, and the heat dissipation device 3 are all located inside the accommodation space formed by the housing 5. The heat dissipation device 3 can discharge the cooled steam to the outside of the housing 5.

[0072] The technical features of the above-disclosed embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered to be within the scope described in this specification.
