[0001] This utility model relates to the technical field of steam ovens, and in particular to a steam oven integrated machine. Background Technology

[0002] A steam oven is a household appliance capable of both steaming and baking. Various steam ovens are disclosed in existing technology. For example, Chinese utility model patent CN218852449U discloses an embedded large-capacity steam oven. This steam oven includes a main body, which is rectangular in shape and hollow inside. A steam oven chamber is located inside the main body. The back of the steam oven chamber is connected to the main body via a first fixing rod, and the bottom of the steam oven chamber is connected to the main body via a second fixing rod. The steam oven chamber includes a steam oven body, which is also rectangular in shape and hollow inside. The front side of the steam oven body is open. An electric heating element is mounted on the top surface of the steam oven body via a support frame.

An evaporation plate is mounted on the bottom surface of the steam oven body and is electrically connected to the external integrated stove controller. A steam recovery device is located on the side of the steam oven chamber.

[0003] The steam oven mentioned above does not have a steam and condensate collection structure inside its steam oven chamber, which makes it easy for condensate to flow down the inner wall of the steam oven chamber or drip onto the steamed food, causing damage to the food surface and hindering the efficient recovery of steam by its steam recovery device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steam oven that uses a steam gathering chamber to gather and collect water vapor, reducing condensation damage to food and improving steam recovery efficiency.

[0005] This utility model discloses a steam oven, comprising a main body, a door, an evaporator, and a heating element. The main body houses a steam oven chamber. A loading / unloading port is located on the front side of the main body. The lower part of the door is hinged to the lower part of the loading / unloading port. The evaporator is installed at the bottom of the steam oven chamber, and an evaporation tank is mounted on the evaporator. The heating element is installed within the steam oven chamber. The appliance also includes two trays, a suction pipe, a suction pump, and a condenser. The two trays are installed opposite each other on the upper left and right sides of the steam oven chamber. The lower edges of the two trays are connected to the left and right inner walls of the main body, respectively. A steam inlet is located between the upper edges of the two trays and the top wall of the main body. The two trays and the inner wall of the main body form a steam collection chamber. The input end of the suction pipe extends into the two steam collection chambers, and the output end of the suction pipe... The evaporator is connected to the input end of the vacuum pump, and the output end of the vacuum pump is connected to the input end of the condenser. During operation, the door is opened and the food to be steamed or baked is placed into the steaming chamber of the main body of the steam oven. The door is then closed, and the evaporator and heating wire operate, causing the water in the evaporation pool of the evaporator to be heated and evaporated to generate high-temperature steam. The high-temperature steam steams the food. The steam at the top of the steaming chamber of the main body of the steam oven enters the two steam gathering chambers formed by two slotted plates through the steam inlet. The vacuum pump operates to extract the steam from the steam gathering chambers through the vacuum pipe and deliver it to the condenser for condensation. Compared with the existing technology, by setting up steam gathering chambers formed by two slotted plates to gather and collect water vapor, the damage of condensate on the inner wall of the steam oven to the steamed food is reduced, which is conducive to improving the steam recovery efficiency.

[0006] Preferably, it also includes a connector and a return pipe. The output end of the connector is connected to the input end of the condenser, and the output end of the condenser extends into the evaporation tank of the evaporator. The connector is connected to an external water pipe, and the external water is input into the condenser through the connector to cool the steam in the condenser, causing the water vapor to condense and heating the external water. The external water and the condensate are mixed and input into the evaporation tank of the evaporator through the return pipe to realize the recycling of water vapor and external water replenishment.

[0007] Preferably, it also includes two upper chamber doors and two rotating shafts. The top of the steam oven body is provided with two secondary openings, which are respectively connected to the steam gathering chambers formed by two slotted plates. The inner ends of the two upper chamber doors are respectively rotatably mounted on the two secondary openings through the two rotating shafts. The two upper chamber doors close and open the two secondary openings. The volume of the steam gathering chambers formed by the two slotted plates is increased, so that several pieces of tableware can be placed in the two steam gathering chambers. The tableware is sterilized at high temperature by steam. The tableware can be taken out and put in by opening the upper chamber doors. The condensate of the steam during the steam sterilization of the tableware is discharged to the outside and is not recycled.

[0008] Preferably, it also includes two sealing protrusions, which are respectively installed on the inner ends of the two upper chamber doors. When the two upper chamber doors are opened, the ends of the two sealing protrusions are respectively aligned with the upper edges of the two slot plates to seal the steam inlet. By setting two sealing protrusions, when the two upper chamber doors are opened alternately to take out and put in tableware, the sealing protrusions are aligned with the upper edges of the slot plates to seal the steam inlet, preventing steam in the steam oven chamber of the main body of the steam oven from being discharged through the open secondary opening, which could burn people, and also preventing a large amount of steam from being discharged, which could cause a sudden drop in the temperature of the steam oven chamber and affect the steaming of food.

[0009] Preferably, it also includes a vertical shaft and a cover plate. The vertical shaft is rotatably mounted on the evaporator, and the cover plate is mounted on the vertical shaft. The cover plate is used to close and open the evaporation pool of the evaporator. By rotating the cover plate around the vertical shaft, the relative position of the cover plate and the evaporation pool of the evaporator can be adjusted, thereby adjusting the size of the opening of the evaporation pool and adjusting the steam output. By setting a drive component so that the cover plate closes the evaporation pool of the evaporator when the box door is opened, the amount of steam in the steam oven can be reduced, and the risk of steam burns when opening the box door can be reduced.

[0010] Preferably, it also includes a gear, a slide bar, a rack, and a pull rod. The gear is concentrically mounted on the vertical shaft, the slide bar is slidably mounted in the slide groove of the evaporator, and a rack is mounted on the slide bar, meshing with the gear. The inner end of the pull rod is rotatably connected to the slide bar, and the outer end of the pull rod is rotatably connected to the oven door. When the oven door closes the loading and unloading port of the steam oven body, the cover plate opens the evaporation pool of the evaporator, allowing steam to be transported into the steam oven body. When the oven door is opened, the oven door pulls the pull rod outward, and the pull rod pulls the slide bar and rack outward. The rack meshes with and drives the gear to rotate, which in turn drives the vertical shaft and the cover plate to rotate, thereby closing the evaporation pool of the evaporator with the cover plate, reducing steam output and reducing the risk of burns.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a steam gathering chamber composed of two slot plates to gather and collect water vapor, the damage of condensate on the inner wall of the steam oven to the steamed food is reduced, which is conducive to improving the steam recovery efficiency.

Detailed Implementation

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0015] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a steam oven includes a main body 1, a door 2, an evaporator 3, and a heating wire 4. The main body 1 has a steaming / baking chamber inside. A loading / unloading port is located on the front end of the main body 1. The lower part of the door 2 is hinged to the lower part of the loading / unloading port. The evaporator 3 is installed at the bottom of the steaming / baking chamber, and an evaporation tank is provided on the evaporator 3. The heating wire 4 is installed in the steaming / baking chamber. It also includes two slotted plates 5, a suction pipe 6, a suction pump 7, and a condenser 8. The two slotted plates 5 are installed opposite each other on the upper left and right sides of the steaming / baking chamber of the main body 1. The lower edges of the two slotted plates 5... The steam oven body 1 is connected to the left and right inner walls respectively. Steam inlets are provided between the upper edges of the two slot plates 5 and the top wall of the steam oven body 1. The two slot plates 5 and the inner wall of the steam oven body 1 form a steam gathering chamber. The input end of the suction pipe 6 extends into the two steam gathering chambers. The output end of the suction pipe 6 is connected to the input end of the suction pump 7. The output end of the suction pump 7 is connected to the input end of the condenser 8. The steam oven body 1 also includes a connector 9 and a return pipe 10. The output end of the connector 9 is connected to the input end of the condenser 8. The output end of the condenser 8 extends into the evaporation tank of the evaporator 3.

[0016] During operation, the oven door 2 is opened and the food to be steamed or baked is placed into the steaming chamber of the main body 1 of the steam oven. The oven door 2 is then closed, and the evaporator 3 and heating wire 4 operate, causing the water in the evaporation pool of the evaporator 3 to be heated and evaporated to generate high-temperature steam. The high-temperature steam steams the food. The steam at the top of the steaming chamber of the main body 1 enters the two steam gathering chambers formed by the two slot plates 5 through the steam inlet. The air pump 7 operates to extract the steam from the steam gathering chambers through the air extraction pipe 6 and deliver it to the condenser 8. The connector 9 is connected to an external water pipe, and the external water is input into the condenser 8 through the connector 9 to cool the steam in the condenser 8, causing the water vapor to condense and heating the external water. The external water and condensate are mixed and input into the evaporation pool of the evaporator 3 through the return pipe 10, realizing the recycling of water vapor and external water replenishment. Compared with the existing technology, by setting up the steam gathering chambers formed by the two slot plates 5 to gather and collect water vapor, the damage of the condensate on the inner wall of the steam oven to the steamed food is reduced, which is conducive to improving the steam recovery efficiency. Example 2

[0017] like Figures 1 to 4 As shown, based on Embodiment 1, it also includes two upper chamber doors 11 and two rotating shafts 12. The top of the steam oven body 1 is provided with two secondary openings, which are respectively connected to the steam gathering chambers formed by the two slot plates 5. The inner ends of the two upper chamber doors 11 are respectively rotatably mounted on the two secondary openings through the two rotating shafts 12. The two upper chamber doors 11 close and open the two secondary openings. It also includes two sealing convex plates 13, which are respectively mounted on the inner ends of the two upper chamber doors 11. When the two upper chamber doors 11 are open, the ends of the two sealing convex plates 13 are respectively connected to the upper edges of the two slot plates 5 to close the steam inlet.

[0018] The volume of the steam gathering chamber formed by the two trough plates 5 is increased so that a number of tableware can be placed in the two steam gathering chambers. The tableware is sterilized at high temperature by steam. When the tableware is taken out by opening the upper box door 11, the sealing convex plate 13 is connected to the upper edge of the trough plate 5 to seal the steam inlet. This prevents the steam in the steam oven 1 from being discharged through the open secondary opening, which could burn people. It also prevents a large amount of steam from being discharged, which could cause a sudden drop in the temperature of the steam oven and affect the steaming of food. The condensate water from the steam sterilization of the tableware is discharged to the outside and is not recycled. Example 3

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, based on Embodiment 1, it also includes a vertical shaft 14 and a cover plate 15. The vertical shaft 14 is rotatably mounted on the evaporator 3, and the cover plate 15 is mounted on the vertical shaft 14. The cover plate 15 is used to close and open the evaporation pool of the evaporator 3. It also includes a gear 16, a slide rod 17, a rack 18, and a pull rod 19. The gear 16 is concentrically mounted on the vertical shaft 14. The slide rod 17 is slidably mounted in the slide groove of the evaporator 3. The rack 18 is mounted on the slide rod 17 and meshes with the gear 16. The inner end of the pull rod 19 is rotatably connected to the slide rod 17, and the outer end of the pull rod 19 is rotatably connected to the door 2.

[0020] The cover plate 15 is rotated around the vertical axis 14 to adjust the relative position of the cover plate 15 and the evaporation pool of the evaporator 3, thereby adjusting the opening size of the evaporation pool and adjusting the steam output. When the door 2 closes the loading and unloading port of the steam oven body 1, the cover plate 15 opens the evaporation pool of the evaporator 3, allowing steam to be transported into the steam oven body 1. When the door 2 is opened, the door 2 pulls the pull rod 19 outward, and the pull rod 19 pulls the slide rod 17 and the rack 18 outward. The rack 18 meshes with the drive gear 16 to rotate, and the gear 16 drives the vertical axis 14 and the cover plate 15 to rotate, thereby closing the evaporation pool of the evaporator 3 with the cover plate 15, reducing the steam output, reducing the amount of steam in the steam oven, and reducing the risk of steam burns when the door 2 is opened.

[0021] like Figures 1 to 6 As shown, this utility model discloses a steam oven. During operation, the door 2 is first opened, and the food to be steamed or baked is placed into the steam oven chamber of the main body 1. The door 2 is then closed, and the cover 15 opens the evaporator 3's evaporation tank. The evaporator 3 and heating wire 4 operate, heating and evaporating the water in the evaporator 3's evaporation tank to generate high-temperature steam. This high-temperature steam steams the food. Afterward, the steam from the top of the steam oven chamber of the main body 1 enters through the steam inlet into two steam collection chambers formed by two slotted plates 5. The suction pump 7 operates, extracting the steam from the steam collection chambers through the suction pipe 6 and sending it to the condenser 8 for condensation. The condensate and... External water flows back to the evaporation tank of evaporator 3 through return pipe 10 for recycling. When tableware sterilization is required, open the upper door 11 and place the tableware into the two steam gathering chambers through the secondary opening. Close the upper door 11 and use steam to sterilize the tableware at high temperature. After steaming and baking are completed, open the door 2. The door 2 pulls the lever 19 outward. The lever 19 pulls the slide bar 17 and rack 18 outward. The rack 18 meshes with the drive gear 16 to rotate. The gear 16 drives the vertical shaft 14 and the cover plate 15 to rotate, thereby closing the evaporation tank of evaporator 3 with the cover plate 15, reducing steam output and reducing the risk of burns. The steamed and baked food can then be taken out.

[0022] The main functions achieved by this utility model are: 1. By setting up a steam gathering chamber composed of two trough plates 5, water vapor is gathered and collected, reducing the damage of condensate on the inner wall of the steam oven to the steamed food, which is conducive to improving steam recovery efficiency. 2.
