[0026] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0027] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0029] An embodiment of this utility model provides an oven that can reduce the temperature of the door, such as... Figure 1-5As shown, the oven includes an oven body 100 and a door 200 located on the front of the oven body 100 and capable of opening and closing. The door 200 can be opened, allowing the user to place food to be baked into the oven body 100 or remove baked food from the oven body 100. The door 200 can also be closed to keep food warm. The oven body 100 contains a fan 300 and an air inlet 310. A first inclined surface 111 is provided on the front of the oven body 100. One end of the air inlet 310 is connected to the air inlet of the fan 300, and the other end forms an air inlet 311 on the first inclined surface 111. The door 200 has a flow passage 400, and a second inclined surface 221 is provided on the top of the door 200. The flow passage 400 forms a first opening 401 at the bottom of the door 200, and a second opening 402 on the second inclined surface 221. In the direction of rearward extension, the heights of the first inclined surface 111 and the second inclined surface 221 gradually decrease, and the second opening 402 faces the air inlet 311.

[0030] When the fan 300 is working, outside air enters the flow channel 400 through the first opening 401, and then is blown out obliquely upward from the second opening 402, and then flows directly to the air inlet 311 to enter the air inlet channel 310. This shortens the path of airflow from the second opening 402 to the air inlet 311, making the airflow smoother, accelerating the airflow, and improving the cooling effect of the door 200.

[0031] In some embodiments, the first inclined surface 111 and the second inclined surface 221 are arranged in parallel, so that the extension path of the second opening 402 coincides with the extension path of the air inlet 311. The second opening 402 can be directly opposite the air inlet 311, which further shortens the path of airflow from the second opening 402 to the air inlet 311, further accelerates the airflow, and further improves the cooling effect of the door 200.

[0032] In some embodiments, the front side of the oven body 100 has a groove 110, a first inclined surface 111 is disposed on the top wall of the groove 110, the door 200 includes a front plate 210 and a door assembly 220 fixed to the rear side of the front plate 210, an airflow channel 400 is disposed within the door assembly 220, a second inclined surface 221 is located on the top surface of the door assembly 220, and a first opening 401 is disposed on the bottom surface of the door assembly 220. When the door 200 is closed, the door assembly 220 is inserted into the groove 110. Thus, the second opening 402 can be closer to the air inlet 311, shortening the distance from the second opening 402 to the air inlet 311, further shortening the path of airflow from the second opening 402 to the air inlet 311, further accelerating airflow, and further improving the cooling effect of the door 200.

[0033] In addition, the presence of the front panel 210 allows the door assembly 220 and the air inlet 311 to be concealed, improving the overall appearance. The door assembly 220 is inserted into the recess 110 and can contact the rear side wall of the recess 110 to improve the sealing performance of the door 200 when closed.

[0034] Furthermore, the oven body 100 is also provided with an air outlet 320. One end of the air outlet 320 is connected to the air outlet of the fan 300, and the other end forms an air outlet 321 on the front side of the oven body 100. The fan 300 draws in the gas into the air outlet 310, the gas flows through the air outlet 320, and finally exits through the air outlet 321 to promptly remove the hot air inside the door 200.

[0035] Furthermore, a panel assembly 120 is provided on the top of the front side of the oven body 100. When the door 200 is closed, a gap 121 is formed between the door 200 and the bottom surface of the panel assembly 120, with the air vent 321 facing the gap 121. Therefore, when the door 200 is closed, the door 200 does not cover the air vent 321, and the airflow blown from the air vent 321 will be completely discharged from the oven through the gap 121.

[0036] The panel assembly 120 may include a panel and a display box fixed to the back side of the panel. The display box may be equipped with a display screen and buttons to display relevant information about the oven on the panel, facilitating human-machine interaction.

[0037] In some embodiments, the oven body 100 is provided with a receiving cavity 101 for placing food to be baked. When the door 200 is open, the receiving cavity 101 is exposed; when the door 200 is closed, the door 200 covers the receiving cavity 101. A steam generator is also provided inside the oven body 100, and the steam generator is connected to the receiving cavity 101. The steam generator can produce steam, which is then delivered to the receiving cavity 101 to heat the food. Thus, the oven in this embodiment becomes a steam oven.

[0038] The accommodating cavity 101 may have an opening formed on the rear sidewall of the groove 110 in the above embodiment.

[0039] In some embodiments, a condenser pipe 330 is fixed inside the air outlet duct 320, and the condenser pipe 330 is connected to the accommodating cavity 101. When the steam in the accommodating cavity 101 reaches a certain density, the pressure in the cavity increases, and some steam can enter the condenser pipe 330. The temperature of the airflow in the air outlet duct 320 is lower than the temperature of the steam in the condenser pipe 330, which can reduce the temperature of this part of the steam and create a micro-pressure cooking environment in the accommodating cavity 101, thereby improving the cooking effect.

[0040] Furthermore, the condenser tube 330 has through vent holes on its circumference, through which steam can be discharged to prevent the gas pressure in the accommodating cavity 101 from increasing further.

[0041] In some embodiments, a temperature sensor is fixed on the condenser pipe 330, and a controller is provided inside the oven body 100. Both the fan 300 and the temperature sensor are connected to the controller. When the temperature detected by the temperature sensor is higher than the preset temperature, the controller controls the fan 300 to start working. When the temperature detected by the temperature sensor is lower than the preset temperature, it indicates that the pressure inside the accommodating cavity 101 is still low, and the gas inside the accommodating cavity 101 has not yet been discharged through the condenser pipe 330. Therefore, the fan 300 does not need to be started, which can save energy.

[0042] The preset temperature can be determined by those skilled in the art based on the actual situation; for example, it can be 60°.

[0043] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
