As shown in fig. 2, the steam oven 100 includes a liner 2, the liner 2 is located in a housing 1, the liner 2 and a oven door 1a form a cooking cavity of the steam oven 100, and a placing space for food materials is formed in the cooking cavity.

The oven door 1a is used for opening or closing a cooking cavity, when food is needed to be cooked, the cooking cavity is opened by the oven door 1a, then food to be cooked is placed in the cooking cavity, the cooking cavity is closed by the oven door 1a, a steam oven is started, the food to be cooked is cooked, and the food is taken out after the cooking is finished.

For example, as shown in fig. 2, the steam oven 100 may be provided with a shelf provided in the inner container 2 and fixedly connected with the inner container 2, the shelf being used for placing food materials.

As shown in fig. 3, the steam oven 100 further comprises a water storage tank 3, a water inlet pipe 4, a power piece 5, a steam generator 6, a water-steam separator 7 and an air inlet pipe 8.

Illustratively, the water storage tank 3 is located above the liner. The water storage tank 3 is used for storing clean water for generating steam, and by arranging the water storage tank 3, frequent water addition into the steam oven 100 can be avoided, thereby being beneficial to improving the use convenience of the steam oven 100.

Illustratively, a first end of the inlet pipe 4 communicates with the water storage tank 3. Clean water stored in the water storage tank 3 can be led out through the water inlet pipe 4.

Illustratively, a power member 5 is provided on the inlet tube 4 for driving the flow of liquid within the inlet tube 4.

For example, the power member 5 may be a water pump.

Illustratively, the inlet of the steam generator 6 communicates with the second end of the inlet pipe 4. Thus, the clean water stored in the water storage tank 3 may flow into the steam generator 6 through the water inlet pipe 4.

Illustratively, the steam generator 6 may change the water within the steam generator 6 to steam by heating.

Illustratively, the inlet of the water-vapor separator 7 communicates with the outlet of the steam generator 6, and the first outlet of the water-vapor separator 7 communicates with the inlet of the steam generator 6 and forms a communicating vessel with the steam generator 6.

Illustratively, the water-vapor separator 7 may separate the gas-liquid mixture flowing therein, and may return the separated liquid to the steam generator 6 to continue converting the liquid into steam, and may transfer the separated steam to the inner container.

Illustratively, one end of the air inlet pipe 8 is communicated with the second outlet of the steam generator 6, and the other end of the air inlet pipe 8 is communicated with the liner 2.

Illustratively, the steam separated by the steam separator 7 may be introduced into the inner container 2 through the air inlet pipe 8 to cook the food material in the inner container 2.

Through the above arrangement, when cooking food, the power piece 5 is started first, water in the water tank 3 can enter the steam generator 6 and the water vapor separator 7 through the water inlet pipe 4, and the water level in the steam generator 6 is equal to the water level in the water vapor separator 7, under the action of the steam generator 6, steam firstly enters the water vapor separator 7 through the inlet of the water vapor separator 7, then in the steam flowing process, cooled water drops can fall in the water vapor separator 7, and finally dry steam can enter the inner container 2 (not shown in fig. 3) through the second outlet of the water vapor separator 7 and the air inlet pipe 8 so as to cook food in the inner container 2.

Illustratively, the steam oven 100 further includes a water return pump. After the cooking is finished, the water return pump is started to pump out the residual water in the steam generator 6 and the water-vapor separator 7 into the water storage tank 3, so that the water is recycled.

In addition, due to the existence of the water-vapor separator 7, the water in the steam can be cooled and stored in the water-vapor separator 7, and the steam entering the inner container 2 is dry steam, so that the situation that the surface of the food is wet after the food is cooked can be avoided, and the cooking effect is better.

After the cooking is finished, the cooking cavity is still filled with high-temperature steam before the oven door 1a is opened, and if the oven door 1a is directly rotated at the moment, the cooking cavity is opened, the high-temperature steam in the cooking cavity can be directly discharged, so that operators are easy to be scalded.

Therefore, in the related art, an exhaust pipe is provided between the liner and the housing, and the liner is provided with an exhaust hole. The first end and the exhaust hole intercommunication of blast pipe, the second end and the outside intercommunication of casing of blast pipe, and then can discharge the steam in the inner bag to the casing outside. So as to avoid high-temperature steam scalding people when a user opens the door body of the steam oven. However, the high temperature steam is easy to form condensed water at the second end of the exhaust pipe after being discharged, and the condensed water drops down to cause the pollution of a kitchen of a user and the damp of the kitchen. In addition, the temperature of the steam discharged from the second end of the exhaust pipe is still high, which is easy to cause injury to users.

In another implementation, for a steam oven with larger capacity, because of larger space, a condensing structure can be arranged to condense high-temperature steam and then guide the high-temperature steam into the bottom of the liner. However, this method is likely to cause excessive water in the inner container, and there is a risk of spillage. After the steam oven is used, the user is required to manually clean the condensed water at the bottom of the inner container, so that the energy consumption and the cleaning time of the user are increased, the water pump is inevitably required to be used when the condensed water is led into the inner container from the condensation structure, the noise problem can be caused, and the user can confuse the reason for the noise generation and even consider the problem as the quality problem.

Based on this, as shown in fig. 4 and 5, the steam outlet 2A is opened on the inner container 2, and the steam oven 100 includes a condensing unit 9 and a heating unit 10. The condensing assembly 9 is located in the shell 1, the condensing assembly 9 is provided with a condensing cavity Q communicated with the steam outlet 2A, an air outlet hole 9A is formed in the top of the condensing assembly 9, and the condensing cavity Q is communicated with the outside through the air outlet hole 9A. Referring to fig. 6 to 10, a heating assembly 10 is disposed in the housing, the heating assembly 10 is disposed on the condensing assembly 9, and the heating assembly 10 is used for heating the condensing assembly 9.

Illustratively, excess steam within the bladder 2 may be vented through the steam outlet 2A.

In some examples, as shown in fig. 4, the steam outlet 2A is located at an upper portion of the liner 2. The condensing unit 9 is located above the liner 2.

The temperature of the steam is relatively high, so that in the steam oven 100, the steam is mostly concentrated above the inner container 2, and the steam outlet 2A is arranged at the upper part of the inner container 2, so that the steam in the inner container 2 is facilitated to be discharged through the steam outlet 2A quickly.

In addition, the condensing assembly 9 is arranged above the liner 2, and after the steam is discharged through the steam outlet 2A, the steam can conveniently enter the condensing assembly 9 without other power components, so that the design difficulty of the steam oven can be simplified.

As shown in fig. 4, 5 and 11, an exhaust pipe 11 is provided between the liner 2 and the condensation module 9. One end of the exhaust pipe 11 is communicated with a steam outlet 2A on the liner 2, and the other end of the exhaust pipe 11 is communicated with a condensation cavity Q. After passing through the steam outlet 2A, the excessive steam in the liner 2 enters the exhaust pipe 11 and finally enters the condensation chamber Q to be condensed into condensed water.

It will be appreciated that the exhaust pipe 11 is located above the liner 2.

For example, the number of exhaust pipes 11 may be one or more. When the number of exhaust pipes 11 is plural, the exhaust speed of the steam in the liner 2 can be increased.

Illustratively, the number of the steam outlets 2A on the liner 2 is plural, the number of the exhaust pipes 11 is plural, one exhaust pipe 11 is provided on one steam outlet 2A, and the number of the steam outlets 2A may be set corresponding to the number of the exhaust pipes 11.

For example, the number of the steam outlets 2A is one, and the number of the exhaust pipes 11 is one; the number of the steam outlets 2A is two, and the number of the exhaust pipes 11 is two; the number of the steam outlets 2A is three, the number of the exhaust pipes 11 is three, or the number of the steam outlets 2A and the number of the exhaust pipes 11 may be other numbers, which is not limited in the present disclosure.

As shown in fig. 4 and 5, the number of steam outlets 2A and the number of exhaust pipes 11 are both exemplified in the embodiment of the present disclosure.

Illustratively, the condensing assembly 9 is configured to cool down the vapor exiting the liner 2.

As shown in fig. 4 and 5, after the steam in the liner 2 is discharged into the condensation chamber Q of the condensation assembly 9 through the steam outlet 2A, the temperature is reduced and condensed into condensed water, and the condensed water is stored in the condensation chamber Q. Therefore, the above arrangement can prevent the steam in the steam oven 100 from being directly discharged to the outside and prevent the high temperature steam from scalding the user. And the condensed water formed after the high-temperature steam is directly discharged can be prevented from falling on the user cabinet, so that the pollution of the user cabinet and the kitchen humidity can be avoided.

Compared with the other implementation mode, the risk of overflowing due to excessive water quantity in the inner container can be avoided. And the condensed water can be directly stored in the condensing cavity Q without introducing other water storage components, so that a water pump is not required to be additionally arranged, the noise problem caused by the water pump can be avoided, and the use experience of a user is improved.

Illustratively, the number of the air outlet holes 9A may be one or more.

For example, as shown in fig. 7, the condensing unit 9 is provided with a plurality of air outlet holes 9A.

Illustratively, the air outlet hole 9A may be elongated, and the width of the elongated shape is smaller, so that the strength of the condensation assembly 9 is prevented from being affected by forming a larger gap in the condensation assembly 9.

By arranging the air outlet hole 9A on the condensation component 9, condensed water in the condensation cavity Q can be evaporated into water vapor and volatilized to the outside through the air outlet hole 9A. Thereby avoid the condensate water in the condensation chamber Q too much to avoid the condensate water to flow back to the inner bag 2 from steam outlet 2A through blast pipe 11 and drip on food material, avoid influencing the taste of food material.

Illustratively, the heating assembly 10 may be a heating film.

The heating film is a heating wire coiled structure, so that the heating component 10 can heat condensed water in the condensing component 9 more uniformly, and the user is prevented from being scalded by high-temperature steam generated by overhigh temperature at a certain position.

The heating assembly 10 may be attached to the bottom or side of the condensing assembly 9 by an adhesive, for example.

The heating component 10 can produce the high temperature in the course of the work, after setting up heating component 10 on condensation subassembly 9, above-mentioned high temperature can heat the comdenstion water in the condensation subassembly 9 to accelerate the evaporation rate of comdenstion water, can get rid of the comdenstion water in the condensation subassembly 9 more fast, consequently can avoid the comdenstion water in the condensation chamber Q of condensation subassembly 9 too much and flow back to inner bag 2 whereabouts on food material from steam outlet 2A through blast pipe 11, thereby avoid influencing the taste of food material.

For example, when there is more condensate in the condensate chamber Q, the heating assembly 10 may be activated to increase the evaporation rate of the condensate. When there is less condensate in the condensation chamber Q, the heating assembly 10 may be turned off, relying only on natural evaporation of the condensate.

Illustratively, during the heating stage of the steam oven 100, the amount of steam in the steam oven 100 is relatively large, and the heating assembly 10 can be stopped at this time, so that the steam oven 100 can be prevented from discharging a large amount of obvious steam during operation, which is beneficial to improving the use experience of users.

Illustratively, after the steam oven 100 is finished, the heating assembly 10 may continue to operate for a period of time to ensure that the condensed water in the condensing chamber Q is removed as completely as possible.

Through above-mentioned setting, can heat the comdenstion water in the condensation chamber Q to accelerate the evaporation rate of comdenstion water, reduce the content of comdenstion water in the condensation chamber Q, can avoid storing too much comdenstion water in the condensation chamber Q and flow backwards to in the inner bag 2 and the whereabouts is on edible material, thereby avoid influencing edible material's taste.

Therefore, in the steam oven 100 provided by the embodiment of the disclosure, by arranging the condensation component 9 and enabling the condensation component 9 to be communicated with the steam outlet 2A of the liner 2, after the steam in the liner 2 is discharged into the condensation cavity Q of the condensation component 9 through the steam outlet 2A, the steam is condensed into condensed water and stored in the condensation cavity Q. Therefore, it is possible to prevent the steam inside the steam oven 100 from being directly discharged to the outside and to prevent the user from being scalded by the high-temperature steam. And the condensed water formed after the high-temperature steam is directly discharged can be prevented from falling on the user cabinet, so that the pollution of the user cabinet and the kitchen humidity can be avoided. Through set up venthole 9A and heating element 10 on condensation subassembly 9, can heat the comdenstion water in the condensation chamber Q through heating element 10 to accelerate the evaporation rate of comdenstion water, reduce the content of comdenstion water in the condensation chamber Q, can avoid in the condensation chamber Q comdenstion water too much and flow backwards to in the inner bag 2 and the drip on edible material, thereby avoid influencing edible material's taste.

In some embodiments, as shown in fig. 12A and 12B, the steam oven 100 further includes a blower assembly 12, the blower assembly 12 being located within the enclosure 1, and the blower assembly 12 being located above the condensing assembly 9. Referring to fig. 4, 13 and 14, the blower assembly 12 has an air duct 13 communicating with the outside, and the blower assembly 12 is configured to discharge air in the air duct 13 to the outside. Wherein, condensation chamber Q communicates with wind channel 13 inside through venthole 9A.

Illustratively, the vapor evaporated from the condensed water in the condensation chamber Q may be diffused into the air duct 13 through the air outlet hole 9A, and after the fan assembly 12 is disposed, the fan assembly 12 may discharge the vapor to the outside, so as to increase the evaporation rate of the condensed water in the condensation chamber Q. As shown in fig. 14, a notch is provided on the housing 1, and air inside the air duct 13 can be blown out from the notch of the housing 1.

In addition, fan subassembly 12 can inhale outside air and blow out to wind channel 13 inside, outside air temperature is lower, above-mentioned low temperature air can cool down condensation subassembly 9, thereby can maintain condensation subassembly 9's low temperature state, be favorable to the high temperature steam in the inner bag 2 to liquefy rapidly after getting into condensation chamber Q of condensation subassembly 9, thereby reduce the steam content that discharges to wind channel 13 inside from the venthole 9A of condensation subassembly 9, consequently can make fan subassembly 12 blow out to the steam moisture content reduction of discharging into outside, can not cause a large amount of steam to discharge and cause kitchen air moist or steam to condense the problem of dripping in steam oven 100 outside. The low-temperature air can cool the steam in the air channel, so that the user is prevented from being scalded after the steam in the air channel is exhausted.

In some embodiments, referring to fig. 9 and 10, the condensing assembly 9 includes a water pan 14 and a heat sink cover 15. The heating assembly 10 is disposed on the drip tray 14. The heat radiation cover plate 15 covers the water receiving disc 14, and the water receiving disc 14 and the heat radiation cover plate 15 form a condensation cavity Q. The heat sink cover 15 forms part of the air duct 13. Wherein, the heat dissipation cover plate 15 is provided with a through hole 15A, and the through hole 15A forms an air outlet hole 9A of the condensing assembly 9.

Illustratively, the material of the drip tray 14 includes a metallic material having good thermal conductivity. The heat dissipating cover 15 is made of a metal material with good heat conductivity. After the heat radiation cover plate 15 and the water receiving disc 14 enclose a condensation cavity Q, steam in the inner container 2 is discharged into the condensation cavity Q of the condensation assembly 9 through the steam outlet 2A, and then is condensed into water drops when meeting condensation, and the water drops are stored in the water receiving disc 14. Thereby preventing the steam in the steam oven 100 from being directly discharged to the outside to prevent the user from being scalded by the high-temperature steam. And the condensed water formed after the high-temperature steam is directly discharged can be prevented from falling on the user cabinet, so that the pollution of the user cabinet and the kitchen humidity can be avoided.

After the heating assembly 10 is arranged on the water receiving tray 14, the condensed water in the water receiving tray 14 can be directly heated so as to accelerate the evaporation speed of the condensed water and reduce the water quantity in the condensing cavity Q.

Illustratively, the drip tray 14 and the heat sink cover 15 may be secured together by welding.

Alternatively, the water pan 14 and the heat radiation cover plate 15 may be fixed together by a connector.

The number of through holes 15A may be one or more, for example.

For example, as shown in fig. 10, a plurality of through holes 15A are provided on the heat radiation cover plate 15.

Illustratively, the through hole 15A may have a long strip shape with a smaller width, so that a larger gap is formed on the heat dissipating cover 15 to avoid affecting the strength of the heat dissipating cover 15.

The through holes 15A are used to form the air outlet holes 9A of the condensing unit 9.

By providing the through holes 15A on the heat radiation cover plate 15, condensed water in the condensation chamber Q can be evaporated into water vapor and volatilized to the outside through the through holes 15A. Thereby avoid the condensate water in the condensation chamber Q too much to avoid the condensate water to flow back to the inner bag 2 from steam outlet 2A through blast pipe 11 and drip on food material, avoid influencing the taste of food material.

In some embodiments, as shown in fig. 10, the steam oven 100 further includes a heat-conductive plate 16, the heat-conductive plate 16 being disposed between the heating assembly 10 and the drip tray 14.

The heat conducting plate 16 has good heat conducting performance, and after the heating component 10 generates high temperature, the high temperature can be quickly conducted to the water receiving disc 14, so that the heating speed of the condensed water in the water receiving disc 14 of the heating component 10 is increased. And the heat conducting plate 16 can further make the heat transferred to the water receiving tray 14 more uniform, so that the situation that the water receiving tray 14 is locally overheated is avoided.

In some embodiments, as shown in fig. 15, the steam oven 100 further comprises: a temperature sensor 17 and a controller 18. A temperature sensor 17 is provided on the condensing assembly 9 for detecting the temperature of the condensing assembly 9 and outputting a sensing signal. The controller 18 is coupled to the temperature sensor 17 and the heating assembly 10, respectively, and is configured to receive the sensing signal of the temperature sensor 17 and control the operating state of the heating assembly 10 according to the sensing signal.

By way of example, the temperature sensor 17 may be a thermocouple or the like.

Illustratively, the temperature sensor 17 is disposed on the drip tray 14.

By way of example, the controller 18 may include a programmable logic controller (Programmable Logic Controller, PLC) or the like.

For example, when the temperature sensor 17 detects that the temperature on the water pan 14 is high, that is, the temperature of the condensed water in the water pan 14 is high, there may be a risk of generating high-temperature steam, the controller 18 may control the heating assembly 10 to stop working or reduce the heating power, so as to avoid scalding the user with the high-temperature steam generated by the excessively high temperature of the condensed water.

For example, when the temperature sensor 17 detects that the temperature of the water tray 14 is low, i.e. the temperature of the condensed water in the water tray 14 is low, which may cause the evaporation rate of the condensed water to be slow, the controller 18 may control the heating assembly 10 to start operating or increase the heating power, so as to avoid the low evaporation rate of the condensed water due to the low temperature of the condensed water.

The working state of the heating assembly 10 can be controlled according to the induction signal by the controller 18, so that the condensate water in the condensation cavity Q maintains proper temperature, and the user is prevented from being scalded by high-temperature steam on the basis of ensuring the evaporation speed of the condensate water.

In the case where the water tray 14 is not completely horizontally placed, uneven distribution of condensed water in the water tray 14 may be caused, and there may be a case where condensed water is present only at a part of the positions of the water tray 14. If the heating assembly 10 is activated in this situation, localized high temperatures within the drip tray 14 may occur or damage to the heating assembly 10 may result from dry heating.

Thus, in some embodiments, as shown in fig. 15, the number of temperature sensors 17 is plural, and the plural temperature sensors 17 are used to detect temperatures at different positions on the condensing assembly 9 and output sensing signals. The controller 18 is coupled to a plurality of temperature sensors 17.

The number of temperature sensors 17 may be, for example, two, three, four, or the like. Two temperature sensors 17 are shown in fig. 15.

Illustratively, a plurality of temperature sensors 17 are provided at different locations of the condensing assembly 9, such that the plurality of temperature sensors 17 may detect temperatures at different locations of the drip tray 14.

Through the arrangement, under the condition that the temperature difference at different positions of the condensation assembly 9 is large, the controller 18 can stop the heating assembly 10, so that local high temperature in the water receiving tray 14 can be avoided, and the situation that the heating assembly 10 is damaged due to dry burning is avoided.

In some embodiments, as shown in fig. 16, the heating assembly 10 includes a heating wire 19 and a switching member 20. The heating wire 19 is coupled to the controller 18. The switching member 20 is disposed in series on the heating wire 19. The switch component 20 is coupled to the controller 18, and the controller 18 is configured to place the switch component 20 in an on state or an off state according to the sensing signal.

Illustratively, the heating wire 19 may comprise a resistive wire or the like.

Illustratively, the switching element 20 may include a circuit breaker or the like.

For example, as shown in fig. 16, the number of the switching parts 20 may be two.

By providing the switching member 20 in series to the heating wire 19, the heating wire 19 will start to heat up when the switching member 20 is turned on. In case the switching member 20 is opened, the heating wire 19 will stop heating.

For example, after the highest temperature and the lowest temperature detected by the plurality of temperature sensors 17 exceed the limit values, the controller 18 may control the switching part 20 to be in an off state, thereby stopping the heating of the heating wire 19, and thus, it is possible to prevent the heating assembly 10 from being damaged by dry combustion.

In some embodiments, as shown in fig. 4 and 5, the steam oven 100 further includes a water separation bracket 21 positioned in the condensation chamber Q, and in combination with fig. 17, 18 and 19, the water separation bracket 21 is fixedly connected to the water pan 14, and the water separation bracket 21 has a connection hole 21A, and the connection hole 21A is in communication with the steam outlet 2A of the inner container 2.

Illustratively, the material of the water separation bracket 21 may include metal and heat resistant plastic.

Illustratively, the thickness of the water separation support 21 may range from 0.4mm to 1.5mm.

For example, the thickness of the water separation support 21 may be 0.4mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, or the like.

Illustratively, after the steam in the liner 2 enters the exhaust pipe 11, it enters the condensation chamber Q through the connection hole 21A.

Illustratively, the water separation bracket 21 and the drip tray 14 may be fixedly connected by a connector.

In some examples, as shown in fig. 4 and 5, the steam oven 100 further includes a connector 22. One end of the connecting piece 22 penetrates through the water separation bracket 21 and the water receiving disc 14 and is fixedly connected with the liner 2.

By way of example, the attachment 22 may include screws, rivets, or the like.

Illustratively, the number of connectors 22 may be one or more. As shown in fig. 18 and 19, the embodiment of the present disclosure takes the number of the connection pieces 22 as three as an example.

Through the arrangement, the water receiving disc 14 can be fixedly connected with the inner container 2.

In some examples, the steam oven 100 further includes a liner 23 disposed on the water separation support 21, with the connector 22 also extending through the liner 23.

By way of example, the pad 23 may comprise a gasket.

In the case that the gasket 23 is a gasket, the connection between the connection member 22 and the water separation bracket 21 can be increased, and damage to the surface of the water separation bracket 21 caused by the connection member 22 can be avoided.

The number of pads 23 may be one or more, for example.

For example, the size of the connection hole 21A may be set according to the size of the exhaust pipe 11.

Illustratively, as shown in fig. 4, the size of the connection hole 21A is larger than the outer diameter size of the exhaust pipe 11, so that the exhaust pipe 11 may pass through the connection hole 21A, so that the exhaust pipe 11 may exhaust the steam into the condensing chamber Q.

Alternatively, as shown in fig. 5, the size of the connection hole 21A of the water separation bracket 21 is the same as the inner diameter size of the exhaust pipe 11, so that the steam in the exhaust pipe 11 can be ensured to be normally discharged.

It will be appreciated that the water separation bracket 21 has a certain height, so that the position of the connecting hole 21A is higher than the position of the bottom of the water pan, so that the steam in the exhaust pipe 11 can be smoothly introduced into the condensation chamber Q.

Under the condition that more condensed water in the condensation cavity Q exists, the liquid level of the condensed water in the condensation cavity Q can rise, through the arrangement, the position of the connecting hole 21A is higher, and even if the liquid level of the condensed water rises due to the fact that more condensed water in the condensation cavity Q exists, the condensed water can be prevented from flowing back into the inner container 2 through the connecting hole 21A and the exhaust pipe 11, and therefore the influence on the taste of food materials after the condensed water flows back into the inner container 2 can be avoided.

In some examples, the area of the water separation bracket 21 is smaller, so that condensed water can be prevented from collecting on the water separation bracket 21, and the collected condensed water can be prevented from flowing into the liner 2 through the connecting hole 21A and the exhaust pipe 11.

In some examples, the width of the water separation support 21 may be less than the width of the water droplets.

With the above arrangement, water droplets are prevented from forming on the water separation bracket 21, so that condensed water is prevented from collecting on the water separation bracket 21 and finally flowing into the inner container 2 through the air outlet hole 9A.

The foregoing is merely a specific embodiment of the disclosure, but the protection scope of the disclosure is not limited thereto, and any person skilled in the art who is skilled in the art will recognize that changes or substitutions are within the technical scope of the disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
