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 steamers 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 has promoted the emergence of steam baking integrated machines. Since the functions of a steamer and an oven are integrated into one, the steam baking integrated machine effectively reduces the occupation of kitchen space by independent steamers 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 lower externally discharged steam and its temperature. In addition, existing steam baking integrated machines generally have a water tank and need to add water to the inner cavity regularly, which is troublesome to operate and has a relatively high cost. 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 condensation device, and a heat dissipation 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 condensation device is disposed in the inner cavity, and the condensation device includes a condenser, a first water pipe, and a second water pipe. The condenser has an upper cavity and a lower cavity that are not communicated with each other. The air outlet of the exhaust duct is communicated with the lower cavity. The first water pipe connects an external water source to the upper cavity, and the second water pipe connects the upper cavity to the steam generator; the heat dissipation device is disposed on the outer wall of the inner cavity, and the heat dissipation device has a cold air chamber that is communicated with the lower cavity, and the lower cavity is located between the upper cavity and the cold air chamber.

[0006] The steam cooking device provided by the embodiments of the present disclosure allows an external water source to sequentially enter the steam generator through a first water pipe, an upper cavity, and a second water pipe to provide the required water for the steam generator. The setting of the water tank is removed, simplifying the internal water circuit connection, reducing costs, and making the water addition operation convenient and fast. The high-temperature steam coming out of the steam generator enters the lower cavity through the exhaust pipe. Since the bottom of the lower cavity is provided with an air-cooling device, the cold air in the cold air cavity can timely take away the heat at the bottom of the lower cavity, and the water in the upper cavity can cool the top of the lower cavity, enabling the high-temperature steam to be cooled by both air-cooling and water-cooling, quickly reducing the temperature of the high-temperature steam, and thus facilitating the external discharge through the cold air cavity to improve the user's comfort. In the case of too large a temperature difference, the steam can also be condensed into water. The condensed steam returns to the inner container through the exhaust pipe, taking away the heat of the condenser and enabling the water to be reused, improving the steam condensation and reflux effect, saving energy while increasing the working time of the steaming function.

[0007] In some embodiments, the bottom wall of the condenser is attached to the outer wall of the cold air cavity; the material of the condenser is a metal material or an alloy material.

[0008] With such a setting, the metal material has good thermal conductivity. The bottom wall of the condenser being attached to the outer wall of the cold air cavity reduces the distance between the two, increases the contact area, improves the heat dissipation performance of the heat dissipation device for the lower cavity, and better cools the high-temperature steam in the lower cavity.

[0009] In some embodiments, the heat dissipation device includes a heat dissipation fan and a wind guide plate. The wind guide plate and the outer wall of the inner container enclose to form a cold air cavity. The heat dissipation fan is communicated with the cold air cavity, and the bottom wall of the condenser is attached to the wind guide plate.

[0010] With such a setting, the heat dissipation fan can continuously supply cold air to the cold air cavity. While the cold air cavity cools the high-temperature steam in the lower cavity by air-cooling, it can also dissipate the heat inside the inner container, reducing the overall temperature of the steam cooking device.

[0011] In some embodiments, the wind guide plate is provided with an opening, and the condenser is arranged in the opening and at least partially located in the cold air cavity.

[0012] With such a setting, the condenser being at least partially located in the cold air cavity enables the bottom wall of the condenser to directly contact the flowing cooling air current, accelerating the speed of heat transfer and exchange, making the temperature of the bottom wall of the condenser lower, and cooling the high-temperature steam in the lower cavity faster.

[0013] In some embodiments, the outer wall of the condenser is adapted to the opening, and the lower cavity is located in the cold air cavity.

[0014] With such a setting, the contact area between the cooling air flow and the condenser is increased, the speed of heat transfer and exchange is accelerated, the flowing cooling air flow takes away more heat from the bottom of the lower cavity, and the effect of steam condensation and reflux is increased.

[0015] In some of these embodiments, the steam cooking device further includes a water level detection device, which is installed in the upper cavity, and the upper cavity has a preset water level.

[0016] With such a setting, the water level detection device can detect the water level in the upper cavity, ensure that the water level in the upper cavity is always higher than the preset water level, so as to better cool and condense the high-temperature steam in the lower cavity.

[0017] In some of these embodiments, the steam cooking device further includes a solenoid valve, which is installed in the second water pipe. The solenoid valve has an open state and a closed state for controlling the on-off of the second water pipe;

[0018] When the water level detection device detects that the water level in the upper cavity has not reached the preset water level, the solenoid valve is in the closed state; when the steam generator needs water, the solenoid valve is in the open state.

[0019] With such a setting, the water volume is controlled in real time through the cooperation of the solenoid valve and the water level detection device, so that the external water source can conveniently, quickly and timely provide the required water volume, ensure that the water consumption of the steam generator is sufficient, and at the same time keep the upper cavity at the preset water level, thus ensuring the condensation effect on the high-temperature steam in the lower cavity.

[0020] In some of these embodiments, the steam cooking device further includes a water pump; the water pump is installed in the first water pipe. When the water level in the upper cavity has not reached the preset water level, the first water pipe draws in external water through the water pump and enters the upper cavity.

[0021] With such a setting, the logic of water retention in the upper cavity and water intake of the steam generator is realized through the water pump, the first water pipe, the water level detection device, the second water pipe and the solenoid valve. The setting of the water tank is removed, the internal water circuit connection is simplified, the operation is simple, the timely supply of water volume is realized, and the condensation and reflux of high-temperature steam are achieved.

[0022] In some of these embodiments, at least one exhaust hole is opened on the bottom wall of the lower cavity, and the lower cavity is communicated with the cold air cavity through the exhaust hole and the opening; the bottom of the air outlet of the exhaust pipe is lower than the inner surface of the bottom wall of the condenser.

[0023] With such a setting, the high-temperature steam in the lower cavity can enter the cold air cavity through the exhaust hole after cooling, and is discharged after further heat dissipation in the cold air cavity, avoiding the discharged steam being too hot to burn the skin. The bottom of the air outlet being lower than the inner surface of the bottom wall of the condenser facilitates the condensed water of the high-temperature steam to flow back to the steam generator for repeated use, improves the steam condensation and reflux effect, saves energy and improves the working time of the steaming function at the same time.

[0024] In some of these embodiments, the air deflector is provided with an air inlet and at least one air outlet. The air inlet and the air outlet are located on both sides of the condenser. The air inlet is opened upward, and the cooling fan is installed at the air inlet.

[0025] With such an arrangement, the air inlet at the top facilitates the entry of the cooling air flow, improving the smoothness of the cooling air flow in the condensation chamber. Thus, the bottom of the condenser is fully cooled, and the cooled steam is finally discharged from the air outlet of the air deflector, increasing the cooling effect of the air cooling.

[0033] To make the above-mentioned objects, features, and advantages of the embodiments of the present disclosure more obvious and understandable, the following describes in detail the specific embodiments of the embodiments of the present disclosure with reference to the drawings.

Therefore, the embodiments of the present disclosure are not limited by the specific embodiments disclosed below.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0038] Refer to Figure 1 , Figure 1The overall structure of the steaming and baking device 100 in the embodiments of the present disclosure is shown. The present disclosure relates to the technical field of cooking devices. The steaming and baking device 100 of the present disclosure can be a steaming box, an oven, or a steaming and baking integrated machine, etc., which is a cooking device that utilizes the dynamic steam balance technology to retain the original nutritional components of food.

[0039] Embodiments of the present disclosure provide a steaming and baking device 100, which includes an inner container 1, a steam generator (not shown in the figure), a condensation device 2, and a heat dissipation device 3. The inner container 1 has a cooking cavity 11 and an exhaust duct 12 communicating with the cooking cavity 11; the steam generator is disposed in the cooking cavity 11 and at the bottom of the inner container 1. Exemplarily, the cooking cavity 11 can place food, and the steam generator is used to continuously generate high-temperature steam to heat the food until it is cooked; the exhaust duct 12 can discharge the high-temperature steam generated during cooking. The condensation device 2 is disposed in the inner container 1. Exemplarily, the condensation device 2 is disposed above the inner container 1. The condensation device 2 includes a condenser 21, a first water pipe 22, and a second water pipe 23. The condenser 21 has a non-communicating upper cavity 211 and a lower cavity 212, and the air outlet of the exhaust duct 12 communicates with the lower cavity 212. Exemplarily, the high-temperature steam enters the lower cavity 212 through the exhaust duct 12. The first water pipe 22 connects the external water source to the upper cavity 211, and the second water pipe 23 connects the upper cavity 211 to the steam generator. Exemplarily, the external water source can enter the upper cavity 211 through the first water pipe 22 to store water in the upper cavity 211, and when the steam generator needs water, the water in the upper cavity 211 enters the steam generator through the second water pipe 23. The heat dissipation device 3 is disposed on the outer wall of the inner container 1. Exemplarily, the heat dissipation device 3 is disposed above the inner container 1. The heat dissipation device 3 has a cold air cavity 31, and the cold air cavity 31 communicates with the lower cavity 212, and the lower cavity 212 is located between the upper cavity 211 and the cold air cavity 31. Exemplarily, the cooling air flow can flow in the cold air cavity 31.

[0040] The steaming and baking device 100 provided by the embodiments of the present disclosure cancels the setting of using a water tank to supply water to the steam generator, reduces costs, adopts the method of supplying water from an external water source, avoids the operation of adding water to the water tank on time, is convenient and fast, and also avoids the failure of the steaming and baking device 100 caused by insufficient water in the water tank. The water provided externally can sequentially enter the inner container through the first water pipe 22, the upper cavity 211, and the second water pipe 23 to supply the required water to the steam generator, and when the water passes through the upper cavity 211, it can also cool and condense the high-temperature steam in the lower cavity 212. The internal water supply waterway connection is simple, which solves the problem of inconvenient water addition operation and cools the high-temperature steam at the same time.

[0041] In addition, for the steam cooking device 100 provided by the embodiments of the present disclosure, the high-temperature steam coming out of the steam generator enters the lower cavity 212 through the exhaust duct 12. Since the lower cavity 212 is located between the upper cavity 211 and the cold air cavity 31, the cooling air flow in the cold air cavity 31 can take away the heat of the high-temperature steam at the bottom of the lower cavity 212, and the water in the upper cavity 211 can cool the high-temperature steam at the top of the lower cavity 212, so that the high-temperature steam is cooled by both air cooling and water cooling, and the temperature of the high-temperature steam can be rapidly reduced, thus facilitating the external discharge through the cold air cavity 31 to improve the user's comfort.

[0042] In addition, when the temperature difference between the lower cavity 212 and the upper cavity 211 and the cold air cavity 31 is too large, the high-temperature steam can be condensed into water. After the steam is condensed into water, it returns to the inner container 1 through the exhaust duct 12, takes away part of the heat of the condenser 21 and enables the steam to be reused, improving the steam condensation and reflux effect. The temperature of the condensed water is relatively high. After entering the inner container 1, it drips from above or gradually converges to the upper surface of the steam generator, and can quickly turn into steam on the steam generator to continue heating food, saving the energy of the steam cooking device 100 and increasing the working time of the steaming function at the same time.

[0043] Exemplarily, the steam generator is located in the central area at the bottom of the inner container 1, the air port of the exhaust duct 12 located in the cooking cavity 11 is above the steam generator, and the steam generator 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 from all around to the upper surface of the steam generator. Since the temperature of the upper surface of the steam generator is relatively high, the water can be quickly heated to form high-temperature steam and move upward to steam and cook food.

[0044] 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, there are the inner container 1, the heat dissipation device 3 and the condensation device 2 in sequence.

[0045] Exemplarily, the projection area of the cold air cavity 31 in the vertical direction is larger than the projection area of the condenser 21 in the vertical direction. With such a setting, the cold air cavity 31 can dissipate heat from both the condenser 21 and the inner container 1 at the same time.

[0046] 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.

[0047] Exemplarily, the condenser 21 is an integral structure. The volume of the upper cavity 211 of the condenser 21 is smaller than the volume of the lower cavity 212. In other embodiments, the condenser 21 can also be a split structure.

[0048] Exemplarily, the position of the first water pipe 22 in the upper cavity 211 is higher than the position of the second water pipe 23 in the upper cavity 211. The first water pipe 22 and the second water pipe 23 are respectively located on both sides of the upper cavity 211. In other embodiments, the first water pipe 22 and the second water pipe 23 may be located on the same side wall of the upper cavity 211. The positions of the first water pipe 22 and the second water pipe 23 in the upper cavity 211 are not limited.

[0049] Reference Figure 1 and Figure 2 , in some of these embodiments, the bottom wall of the condenser 21 abuts against the outer wall of the cold air cavity 31. With this arrangement, the distance between the condenser 21 and the cold air cavity 31 is reduced, the contact area between the two is increased, the heat dissipation performance of the heat dissipation device 3 for the lower cavity 212 is improved, and the high-temperature steam in the lower cavity 212 is better cooled.

[0050] The material of the condenser 21 is a metal material or an alloy material. Since metal materials have good heat conduction performance and heat transfer is rapid, the heat dissipation effect of double cooling of water cooling and air cooling can be improved. Exemplarily, the material of the condenser 21 is aluminum alloy. In other embodiments, the material of the condenser 21 may also be stainless steel or other materials with good heat conduction performance.

[0051] Reference Figure 1 and Figure 2 , in some of these 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 a cold air cavity 31. The heat dissipation fan 32 is communicated with the cold air cavity 31, and the bottom wall of the condenser 21 abuts against the wind guide plate 33. With this arrangement, the heat dissipation fan 32 can continuously supply cold air to the cold air cavity 31. While the cold air cavity 31 cools the high-temperature steam in the lower cavity 212 by air cooling, it can also dissipate the heat inside the inner container 1 and reduce the overall temperature of the steaming and baking device 100.

[0052] Exemplarily, the wind guide plate 33 and the upper surface of the inner container 1 enclose a cold air cavity 31. The side of the wind guide plate 33 where the heat dissipation fan 32 is located is the rear part. The condenser 21 is located in the middle of the wind guide plate 33 and the area of the middle part of the wind guide plate 33 covering the inner container 1 is the smallest. The area of the front part of the wind guide plate 33 covering the inner container 1 is larger than the area of the rear side of the wind guide plate 33 covering the inner container 1. With this arrangement, when the cooling air flow enters from the rear and passes through the middle part, the flow rate is relatively fast and the temperature is relatively low, and the cooling effect on the high-temperature steam in the condenser 21 is significant. When the cooling air flow enters the front part of the wind guide plate 33, the contact area with the inner container 1 is increased, the flow rate of the cooling air flow becomes slower, and part of the heat outside the inner container 1 can be taken away.

[0053] Reference Figure 2In some embodiments, the air guide plate 33 is provided with an opening 331, and the condenser 21 is disposed at the opening 331 and at least partially located in the cold air chamber 31. In this configuration, the condenser 21 is at least partially located in the cold air chamber 31 so that the bottom wall of the condenser 21 can directly contact the flowing cooling airflow, which speeds up the speed of heat transfer and exchange, so that the temperature of the bottom wall of the condenser 21 is lower, and the high-temperature steam in the lower cavity 212 is cooled more quickly.

[0054] Exemplarily, the middle part of the condenser 21 is located at the opening 331 of the cold air chamber 31. Or the part of the condenser 21 connected to the air outlet of the exhaust duct 12 is located at the opening 331 of the cold air chamber 31. Exemplarily, the opening 331 can be square, circular, diamond or other irregular shapes. In other embodiments, part of the lower cavity 212 of the condenser 21 can be located inside the cold air chamber 31 through the opening 331, so that part of the side wall and part of the bottom wall of the lower cavity 212 can contact the flowing cooling airflow.

[0055] refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the outer wall of the condenser 21 is adapted to the opening 331, and the lower cavity 212 is located in the cold air cavity 31. This arrangement increases the contact area between the cooling airflow and the condenser 21, speeds up the heat transfer and exchange, and the flowing cooling airflow takes away more heat from the bottom of the lower cavity 212, increasing the effect of steam condensation reflux.

[0056] 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 entire lower cavity 212 of the condenser 21 can be accommodated in the cold air cavity 31, so that the side wall and the bottom wall of the lower cavity 212 can contact the flowing cooling airflow.

[0057] Exemplarily, the bottom wall of the condenser 21 is a plane. In other embodiments, the bottom wall of the condenser 21 may also be provided with cooling fins to further dissipate heat from the condenser 21 .

[0058] refer to Figure 1 and Figure 3 In some embodiments, the steaming and baking device 100 further includes a water level detection device 4, which is installed in the upper cavity 211, and the upper cavity 211 has a preset water level. In this way, the water level detection device 4 can detect the water level of the upper cavity 211, ensuring that the water level of the upper cavity 211 is always higher than the preset water level, so as to better cool down and condense the high-temperature steam in the lower cavity 212.

[0059] Exemplarily, the water level detection device 4 is located on the outer surface of the side wall of the upper cavity 211 and is disposed close to the top wall. In other embodiments, the water level detection device 4 may be disposed on the top wall or the inner surface of the upper cavity 211.

[0060] Reference Figure 1 , in some embodiments, the steaming and baking device 100 further includes a solenoid valve 5. The solenoid valve 5 is installed on the second water pipe 23 and has an open state and a closed state for controlling the on-off of the second water pipe 23. When the water level detection device 4 detects that the upper cavity 211 has not reached the preset water level, the solenoid valve 5 is in the closed state. When the steam generator needs water, the solenoid valve 5 is in the open state. With such a setting, the water volume is controlled in real time through the cooperation of the solenoid valve 5 and the water level detection device 4, enabling the external water source to provide the required water volume conveniently, quickly, and in a timely manner. While ensuring that the water consumption of the steam generator is sufficient, the upper cavity 211 is maintained at the preset water level, thereby ensuring the condensation effect of the high-temperature steam in the lower cavity 212.

[0061] Reference Figure 1 , in some embodiments, the steaming and baking device 100 further includes a water pump 6. The water pump 6 is installed on the first water pipe 22. When the upper cavity 211 has not reached the preset water level, the first water pipe 22 draws in external water through the water pump 6 and enters the upper cavity 211. Exemplarily, the water level detection device 4 is communicatively connected to the water pump 6 and controls the opening and closing of the water pump 6. With such a setting, the logic of water retention in the upper cavity 211 and water intake of the steam generator is realized through the water pump 6, the first water pipe 22, the water level detection device 4, the second water pipe 23, and the solenoid valve 5. The setting of the water tank is removed, simplifying the internal water circuit connection, with simple operation, realizing the timely supply of water volume and the condensation and reflux of high-temperature steam.

[0062] Exemplarily, when the steaming and baking device 100 is to be used, the solenoid valve 5 is in the open state, and the external water source is supplied to the steam generator directly through the first water pipe 22, the upper cavity 211, and the second water pipe 23 under the action of the water pump 6. When the water volume in the steam generator is sufficient, the solenoid valve 5 is in the closed state, the second water pipe 23 is disconnected, and the upper cavity 211 starts to store water until the water level detection device 4 detects that the water level has risen to the preset water level, at which time the water pump 6 stops working. During the use of the steaming and baking device 100, since the water in the steam generator gradually turns into steam and decreases, when the steam generator needs to be refilled with water, the solenoid valve 5 is opened, and the water in the upper cavity 211 flows into the steam generator through the second water pipe 23. At this time, the water level detection device 4 detects a decrease in the water level and activates the water pump 6 to draw water from the external water source through the first water pipe 22 and into the upper cavity 211 until the water volume in the steam generator is sufficient and the solenoid valve 5 is closed, and the water pump 6 is closed when the water level in the upper cavity 211 reaches the preset water level. This cycle repeats.

[0063] Reference Figure 4, in some embodiments, at least one exhaust hole 2121 is formed in the bottom wall of the lower cavity 212, and the lower cavity 212 communicates with the cold air through the exhaust hole 2121 and the opening 331. With this arrangement, the high-temperature steam in the lower cavity 212 can enter the cold air cavity 31 through the exhaust hole 2121 after cooling, and is discharged after further heat dissipation in the cold air cavity 31, avoiding the skin from being burned by the excessively high temperature of the discharged steam.

[0064] Exemplarily, three exhaust holes 2121 are formed in the bottom wall of the lower cavity 212, and the three exhaust holes 2121 are all arranged on the side of the bottom wall of the lower cavity 212 away from the air outlet of the exhaust duct 12. In other embodiments, the number of the exhaust holes 2121 can also be two, four or more. Exemplarily, the sizes of the exhaust holes 2121 are all different. In other embodiments, some of the exhaust holes 2121 can have the same size or all the exhaust holes 2121 can have the same size. Exemplarily, the periphery of the exhaust port protrudes from the bottom wall of the lower cavity 212 to prevent the condensed water from flowing out of the exhaust port into the cold air cavity 31.

[0065] Reference Figure 3 , in some embodiments, the bottom of the air outlet of the exhaust duct 12 is lower than the inner surface of the bottom wall of the condenser 21, which is convenient for the high-temperature steam to condense into water and then flow back to the steam generator for reuse, improving the steam condensation and reflux effect, saving energy and at the same time increasing the working time of the steaming function.

[0066] Exemplarily, the connection part between the air outlet of the exhaust duct 12 and the bottom wall of the condenser 21 is an inclined surface.

[0067] Reference Figure 5 , in some embodiments, an air inlet 332 and at least one air outlet 333 are formed in the air guide plate 33. The air inlet 332 and the air outlet 333 are located on both sides of the condenser 21. The air inlet 332 is formed upward, and the heat dissipation fan 32 is installed at the air inlet 332. With this arrangement, the air inlet 332 at the top is convenient for the cooling air flow to enter, improving the smoothness of the cooling air flow in the condensation cavity, so as to fully dissipate the heat from the bottom of the condenser 21, and the cooled steam is finally discharged from the air outlet 333 of the air guide plate 33, increasing the heat dissipation effect of air cooling.

[0068] Exemplarily, the shape and size of the air inlet 332 are adapted to the heat dissipation fan 32. The air inlet 332 is circular. The air inlet 332 is located at the rear of the heat conduction plate.

[0069] Exemplarily, there are multiple air outlets 333, and the air outlets 333 are located at the front of the heat conduction 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 the heat from the inner container 1 and the condenser 21.

[0070] Reference Figure 1 andFigure 2 Moreover, the steaming and baking device 100 provided by the embodiments of the present disclosure further includes a housing 7, and the inner container 1, the condensation device 2 and the heat dissipation device 3 are all located inside the accommodation space formed by the housing 7. The heat dissipation device 3 can discharge the cooled steam to the outside of the housing 7.

[0071] 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 as the scope recorded in this specification.
