[0031] like Figure 1 , Figure 2 As shown, this embodiment of the present invention provides an integrated steam system, including a water tank 1 and a steam generator 2. The water tank 1 has an internal partition wall 11, which divides the interior of the water tank 1 into a low-temperature chamber 12 and a high-temperature chamber 13. The bottom of the partition wall 11 has a water inlet hole 14, connecting the low-temperature chamber 12 and the high-temperature chamber 13. The high-temperature chamber 13 has a mounting hole at its bottom and a steam outlet at its top. The steam generator 2 is sealed within the mounting hole at the bottom of the high-temperature chamber 13.

[0032] The integrated steam system provided in this embodiment of the utility model, when in use, adds water to the low-temperature chamber 12 of the water tank 1. The water inlet 14 at the bottom of the partition wall 11 connects the high-temperature chamber 13 and the low-temperature chamber 12 into one unit using the principle of communicating vessels, ensuring that the water levels in the high-temperature chamber 13 and the low-temperature chamber 12 are always at the same height. This allows for timely replenishment of water to the high-temperature chamber 13 without the need for a water pump or flow meter. The steam generator 2 and the high-temperature chamber 13 form a sealed space, preventing the generated high-temperature steam from overflowing. A steam outlet is provided above the high-temperature chamber 13, which can be sealed to the air inlet at the top of the cavity assembly 51 of the steam oven via a steam pipe 52 (see...). Figure 5 The integrated steam system provided in this embodiment of the utility model designs the water tank 1 and the steam generator 2 as a whole, eliminating the water pump, flow meter and complex pipeline between the two in the prior art, reducing the volume of the steam system, making the product more compact, reducing the difficulty of the production process and production cost, optimizing the control logic and hardware cost of the steam system, and enhancing the product's ultimate performance.

[0033] In one embodiment of this utility model, the volume of the high-temperature chamber 13 is smaller than the volume of the low-temperature chamber 12, so that when the steam generator 2 is working, it only heats a small amount of water in the high-temperature chamber 13 to achieve the purpose of quickly generating high-temperature steam.

[0034] To make it easier to add water, such as Figures 1-3 As shown, in one embodiment of this utility model, the low-temperature cavity 12 is a cavity with an open top.

[0035] Existing steam generators frequently experience dry burning, failing to provide a continuous supply of high-temperature steam and affecting cooking results. Furthermore, frequent dry burning leads to scale buildup at the bottom of the steam generator, impairing heat transfer and causing it to overheat and burn out, ultimately shortening the overall lifespan of the unit. To address these issues, such as... Figure 3 As shown, in one embodiment of this utility model, a water level sensor is provided on the inner wall of the low-temperature cavity 12. When the level of purified water in the water tank 1 is lower than the height set by the water level sensor, the cooking device (e.g., a steam oven) determines that the water tank is low on water and reminds the user to add water to the low-temperature cavity 12 to prevent the steam generator 2 in the high-temperature cavity 13 from burning out and being damaged. Specifically, the water level sensor includes a first sensor 31 and a second sensor 32. The first sensor 31 is located at the bottom of the low-temperature cavity 12, and the second sensor 32 is located at the top of the low-temperature cavity 12, respectively controlling the minimum and maximum water levels in the low-temperature cavity 12 to maintain the water level in the low-temperature cavity 12 at a suitable height. Preferably, the position of the first sensor 31 is higher than the position of the water inlet 14. This ensures that the purified water in the low-temperature cavity 12 always covers the water inlet 14, preventing the high-temperature steam in the high-temperature cavity 13 from overflowing through the water inlet 14; in addition, it also ensures that when the cooking device detects a water shortage, there is still a small amount of purified water at the bottom of the high-temperature cavity 13, preventing the steam generator 2 from burning out and being damaged. In addition, in traditional steam generators, the water pump only starts drawing clean water from the water tank into the steam generator after the NTC detects that the steam generator is dry-burning. When the clean water enters the high-temperature steam generator, it instantly generates high-temperature and high-pressure steam. This high-temperature and high-pressure steam may push open the door assembly of the cooking equipment (such as a steam oven), causing the high-temperature steam to leak and scald the user. However, the integrated steam system provided in this embodiment can effectively avoid this problem because it can ensure that there is always clean water at the bottom of the high-temperature chamber 13.

[0036] like Figure 1 , Figure 3As shown, in one embodiment of this utility model, the inner wall of the cryogenic chamber 12 is provided with a vertical groove 4, and a float 41 is provided in the groove 4. The groove 4 corresponds to the positions of the first sensor 31 and the second sensor 32, so that the first sensor 31 and the second sensor 32 can detect the position of the float 41, thereby determining the water level in the cryogenic chamber 12.

[0037] like Figure 4 As shown, in one embodiment of this utility model, the steam generator 2 includes an evaporation plate 21, which is sealed within a mounting hole at the bottom of the high-temperature chamber 13. The bottom of the evaporation plate 21 is provided with a heating tube 22, a snap-action thermostat 23, and a temperature sensor 24, which can employ existing technology and will not be described in detail here.

[0038] The heating element 22 may include an inner heating element and an outer heating element, which are welded to the bottom of the evaporator plate 21. The snap-on thermostat 23 and the temperature sensor 24 (evaporator NTC) are fixed to the bottom of the evaporator plate 21 with screws. The evaporator plate NTC monitors the temperature of the evaporator plate 21 in real time. When the temperature exceeds 105°C, the control board determines that the evaporator plate 21 is dry-burning due to lack of water, and the inner and outer heating elements stop working. When the evaporator plate NTC fails and the temperature of the evaporator plate 21 continues to rise to 110°C, the snap-on thermostat 23 activates and cuts off the power supply to the inner and outer heating elements, and the main control board determines that the evaporator NTC has failed. When the evaporator 21 is working, the temperature of the evaporator 21 continues to rise and exceeds 105°C. The evaporator NTC determines that the high-temperature chamber 13 of the water tank is short of water and the evaporator 21 is dry-burning. At the same time, the water level in the low-temperature chamber 12 is higher than the height detected by the first sensor 31, indicating that there is water in the low-temperature chamber 12. At this time, the main control board determines that there is foreign matter blocking the water inlet hole 14 in the low-temperature chamber 12 of the water tank 1, and the panel reminds the user to clean the foreign matter in the low-temperature chamber 12 of the water tank.

[0039] like Figure 5 As shown, this utility model also provides a steam oven, including a shell 5 and a cavity assembly 51 disposed inside the shell 5, as well as the aforementioned integrated steam system. The water tank 1 is disposed above the cavity assembly 51, and the steam outlet is connected to the cavity assembly 51 via a steam pipe 52.

[0040] In one embodiment of this utility model, a water inlet trough 15 is provided on the top of the cryogenic cavity 12, and a baffle 16 is provided on the outer side of the water inlet trough 15. A panel 53 is provided on the front side of the outer casing 5, and the panel 53 is provided with a water inlet 54 corresponding to the baffle 16. The water inlet trough 15 is slidably disposed on the top of the cryogenic cavity 12 and can extend outside the water inlet 54.

[0041] When the steam oven provided by this utility model is working normally, the water inlet trough 15 of the water tank 1 is housed inside the low-temperature cavity 12 of the water tank 1, and the baffle 16 on the front side of the water inlet trough 15 is flush with the panel 53 of the steam oven shell 5. From the outside, the two components appear as a single plane. When the water level is controlled by the first sensor 31 and the second sensor 32, the float 41 can float up and down with the level of the clean water in the low-temperature cavity 12. When the level of the clean water drops, the float 41 drops synchronously to the height monitored by the first sensor 31, the steam oven determines that the water tank 1 is low on water, and the panel 53 displays "Low Water" to remind the user. The water inlet trough 15 moves forward under the action of the built-in motor or spring and pops out the panel 53. The user can add clean water to the low-temperature cavity 12 of the water tank 1 from the outside through the water inlet trough 15. The level of the clean water in the low-temperature cavity 12 of the water tank 1 rises, and the float 41 also rises accordingly. When the height of the float 41 reaches the height monitored by the second sensor 32, the steam oven determines that the water tank 1 is full, and the panel 53 displays "Full Water" to remind the user. If the user continues to add water and the height of the float 41 exceeds the height of the second sensor 32, the water inlet 15 will quickly retract into the water tank 1 under the drive of the built-in motor to prevent the user from overfilling the water and causing the water in the water tank 1 to overflow. After the water is added normally, the user can directly retract the water inlet 15 into the water tank 1 by pressing the baffle 16 of the water inlet 15, or operate the built-in motor or spring through the panel 53 to retract the water inlet 15 into the water tank 1, and make the baffle 16 of the water inlet 15 flush with the panel 53 again.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
