[0003] Condensate water is an inevitable byproduct in the working process of steam oven.During steaming process, the moisture released by food and steam will condense into condensate water after encountering cold.The existing steam oven usually lacks efficient condensate water export mechanism, which leads to the easy backflow of condensate water into the steam cavity, which not only increases the humidity inside the steam cavity, but also may affect the taste of food and the cleanliness of steam oven.Excessive humidity in the internal environment of steam oven may also accelerate the corrosion of parts exposed to the internal environment of steam oven, thereby shortening the service life of the equipment.

[0004] On the other hand, the water vapor released by steam oven during exhaust is usually high in temperature, generally 50-60 degrees Celsius, especially when cooking is just completed, a large amount of high-temperature steam directly discharged may cause scalding risk to users.The existing steam oven exhaust system often ignores this point, lacks effective temperature control measures, so that there is a certain safety hazard for users when operating the steam oven.

[0070] Specifically, the condensing device 4 and water supply device 6 are installed on the top of the steamer body 1, and the steam generating device 7 is installed on the back of the steamer body 1,

[0071] It should be noted that: the water supply device 6 is used to provide water to the steam generating device 7, the steam generating device 7 heats the water into hot steam, the hot steam is delivered into the steaming cavity 2 through the steam outlet 811, the hot steam in the steaming cavity 2 is discharged to the condensing device 4 through the exhaust port 21, and the hot steam is discharged to the outside after being cooled by the condensing device 4.

[0072] As shown in Figures 8-13As shown, the condensing device 4 comprises a condensing shell 41 and a condensing cavity 413 arranged in the condensing shell 41, one side of the condensing shell 41 is provided with an air inlet passage 414 communicating with the condensing cavity 413; the air inlet passage 414 comprises an air inlet 4141 and an air outlet 4142, the air inlet 4141 is directed to the electrical cavity 3 and is provided with a condensing fan 42, the air outlet 4142 is directed to the condensing cavity 413 and is provided with a heat dissipation piece 43, and a condensing plate 44 is arranged directly below the heat dissipation piece 43; the condensing fan 42 extracts air in the electrical cavity 3 and delivers cold air into the condensing cavity 413 through the heat dissipation piece 43;

[0073] A hot steam passage 45 is arranged on the condensing shell 41; one end of the hot steam passage 45 communicates with the air outlet 21, and the other end communicates with the air outlet 4142; the heat dissipation piece 43 is arranged at the outlet of the hot steam passage 45 and is used for condensing part of the hot steam in the hot steam passage 45;

[0074] It should be noted that part of the hot steam in the hot steam passage 45 is condensed into condensed water after encountering the heat dissipation piece 43, and then is subjected to secondary condensation by the condensing plate 44;

[0075] An air outlet 4111 is arranged on the condensing shell 41, the air outlet 4111 communicates the outside with the condensing cavity 413, and the other part of the hot steam in the hot steam passage 45 is output in the direction of the air outlet 4111;

[0076] The pressure difference between the condensing cavity 413 and the hot steam passage 45 is adjusted by adjusting the wind speed of the condensing fan 42, so as to adjust the dryness and humidity in the steam cavity 2;

[0077] It should be noted that when the condensing fan 42 works, cold air is output into the condensing cavity 413; the flow rate in the condensing cavity 413 is fast and the pressure is small; while the flow rate in the hot steam passage 45 is slow and the pressure is large, so that a negative pressure is formed between the hot steam passage 45 and the condensing cavity 413, thereby enabling the hot steam in the hot steam passage 45 to be quickly discharged into the condensing cavity 413.

[0078] Firstly, the condensing device 4 is arranged to adjust the humidity in the steam cavity 2. The arrangement of the condensing device 4, including the combined use of the condensing plate 44 and the heat dissipation piece 43, ensures the effective condensation of hot steam, avoids a large amount of high-temperature steam being directly discharged, and thus reduces the risk of scalding the user. The wind speed of the condensing fan 42 can be further adjusted to adjust the pressure difference between the condensing cavity 413 and the hot steam passage 45, so as to dynamically control the dryness and humidity in the steam cavity 2, and meet the needs of different food steaming.

[0079] Secondly, the condensing device 4 in the design not only serves as a condensing treatment unit for hot steam, but also utilizes the Bernoulli principle to generate negative pressure, thereby accelerating the exhaust process. When the condensing fan 42 is in operation, cold air is output to the condensing cavity 413, causing a fast flow and low pressure state in the condensing cavity 413, while the relative flow in the hot steam passage 45 is slow and the pressure is high, forming a natural negative pressure difference. This negative pressure environment promotes the hot steam in the steam cavity 2 to quickly and efficiently pass through the exhaust port 21 into the hot steam passage 45, and then be discharged to the outside after condensing treatment, effectively improving the exhaust efficiency.

[0080] Moreover, precise humidity control and efficient exhaust mechanism ensure that the steamer can provide users with a more stable and reliable steaming environment.

[0104] As Figure 1 The embodiment also provides a steamer, comprising the humidity balancing structure for the front exhaust steamer.

[0105] Specifically, the steamer includes kitchen appliances such as a steamer that only heats food by water vapor, and also includes kitchen appliances such as a steam oven that combines heat (for example, a heating pipe or the like is provided in the steamer for baking) and water vapor.

[0106] According to the disclosure and teaching of the above description, those skilled in the art of the present application can also make changes and modifications to the above embodiments. Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should also fall within the protection scope of the claims of the present application. In addition, although some specific terms are used in the specification, these terms are only for convenience of description and do not constitute any limitation on the present application.
