Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to built-in cooking devices. Background Technology

[0002] To accommodate the installation space of standardized cabinets, built-in cooking appliances cannot be too wide. For example, a typical built-in steam oven is 60cm wide. This narrow width makes it impossible to place the control panel on the front left or right side of the inner cavity (due to insufficient space). Furthermore, because the temperature directly in front of the inner cavity is too high, the control panel cannot be placed there to protect it. Therefore, the control panel is usually placed at the upper front of the inner cavity. However, in built-in cooking appliances, the air in the cooling duct also exits from the upper front of the inner cavity. Since the cooling duct is usually connected to the inner cavity, the water vapor generated during steaming is expelled with the air in the cooling duct. This water vapor, along with the condensation on the control panel, can interfere with the user's operation of the control panel. Utility Model Content

[0003] Therefore, it is necessary to provide an embedded cooking device to address the above problems.

[0004] To address the above problems, this application provides the following technical solution:

[0005] An embedded cooking device, the embedded cooking device comprising:

[0006] Box;

[0007] The inner liner, located within the box body, has a cooking cavity;

[0008] The door is rotatably connected to the housing; the door is provided with a ventilation channel running through it from front to back.

[0009] A steam generator is connected to the cooking cavity;

[0010] A centrifugal fan, connected to the housing, has an air intake and an air exhaust port;

[0011] The heat dissipation air duct includes a first air duct and a second air duct, both located above the inner liner; the first air duct has a first air inlet and a first air outlet, the first air inlet being connected to the exhaust outlet; the second air duct has a second air inlet and a second air outlet, the second air inlet being connected to the exhaust outlet, and the second air duct being connected to the cooking cavity; the first air outlet and the second air outlet are distributed horizontally, both facing forward, and both directly opposite the airflow channel; and

[0012] The control panel is located on the door and directly above and in front of the first air outlet.

[0013] This built-in cooking device has at least the following beneficial effects:

[0014] In this built-in cooking device, the air blown out by the first air duct passes through the control panel, while the air blown out by the second air duct does not. The water vapor generated during the steaming process is only expelled with the airflow from the second air duct. Therefore, no water vapor passes over the control panel, and no condensation forms, making it convenient for the user to operate the control panel.

[0015] In one embodiment, the door is provided with a cold air channel, the cold air channel having a cold air inlet and a cold air outlet, the cold air inlet penetrating through the bottom side of the door, the cold air outlet penetrating through the bottom wall of the air passage, and the cold air outlet being located directly in front of and below the first air outlet and close to the first air outlet.

[0016] This design serves two purposes. First, outside cold air enters the door through the cold air inlet. After being heated, its density decreases, causing it to rise naturally and eventually exit through the cold air outlet. This facilitates heat dissipation and helps prevent burns to the user. Second, the air blowing out from the first air outlet passes above the cold air outlet, creating a negative pressure above it. This accelerates the airflow within the cold air channel, further aiding in heat dissipation and preventing burns to the user.

[0017] In one embodiment, the second air outlet is positioned away from the cold air outlet.

[0018] This design helps prevent the air blown out from the second air outlet from polluting the inside of the door.

[0019] In one embodiment, the door is further provided with an isolating member, which separates the portion of the air passage that faces the first air outlet from the portion that faces the second air outlet, and the cold air outlet is located on the portion of the air passage that faces the first air outlet.

[0020] This design helps prevent the air blown out from the second air outlet from polluting the inside of the door.

[0021] In one embodiment, the ventilation channel includes a ventilation section and a guide section, wherein the guide section extends gradually from the rear end of the ventilation section and gradually widens.

[0022] This configuration allows the air blowing out from the first and second air outlets to enter the air circulation channel.

[0023] In one embodiment, there are two second air outlets, which are located on both sides of the first air outlet.

[0024] With this configuration, the air containing water vapor in the second air duct is discharged from the positions located on both sides of the first air outlet, which helps to prevent excessive local moisture in the kitchen.

[0025] In one embodiment, the cooking device further includes a water tank, which is located directly above and fitted to the first air duct.

[0026] This design allows the water tank to absorb heat from the first air duct, which in turn helps the first air duct effectively dissipate heat from the cooking equipment. Furthermore, after absorbing heat from the first air duct, the water temperature inside the tank rises, preheating the water. This means that when the water from the tank is supplied to the steam generator of the cooking equipment, it only needs to absorb less heat to evaporate into steam, saving energy and reducing the operating costs of the cooking equipment.

[0027] In one embodiment, the water tank is positioned close to the first air outlet.

[0028] This design helps the water tank absorb heat from the first air duct.

[0029] In one embodiment, the first air duct is composed of a first air duct front section and a first air duct rear section, with the first air duct rear section located behind the first air duct front section; the second air duct is composed of a second air duct front section and a second air duct rear section, with the second air duct rear section located behind the second air duct front section; the first air duct front section and the second air duct front section are distributed along a horizontal direction, and the first air duct rear section and the second air duct rear section are arranged side by side along a vertical direction, with the first air duct rear section located above the second air duct rear section.

[0030] With this configuration, the rear part of the second air duct is relatively close to the inner liner, making it convenient to connect the rear part of the second air duct with the cooking cavity.

[0031] In one embodiment, the first air duct is composed of a first air duct front section and a first air duct rear section, with the first air duct rear section located behind the first air duct front section; the second air duct is composed of a second air duct front section and a second air duct rear section, with the second air duct rear section located behind the second air duct front section; the first air duct front section and the second air duct front section are distributed along a horizontal direction, and the first air duct rear section and the second air duct rear section are arranged side by side along a vertical direction, with the first air duct rear section located below the second air duct rear section.

[0032] With this setup, the first air duct is relatively close to the inner liner, which is beneficial for using the cooler airflow inside the first air duct to dissipate heat from the structures near the inner liner. Attached Figure Description

[0050] See Figures 1 to 9 This application provides an embedded cooking device, which includes a housing 1, an inner liner 2, a door 3, a steam generator 4, a centrifugal fan 5, a heat dissipation duct 6, and a control panel 7. The inner liner 2 is located within the housing 1 and has a cooking cavity 21 in which food is placed for cooking. The door 3 is rotatably connected to the housing 1 and has a ventilation channel 31 extending through it from front to back. The steam generator 4 communicates with the cooking cavity 21. The centrifugal fan 5 is connected to the housing 1 and has an air intake 51 and an exhaust 52. The heat dissipation duct 6 includes a first duct 61 and a second duct 62. The first duct 61 is located above the inner liner 2 and has a first air inlet 6111 and a first air outlet 6121, with the first air inlet 6111 communicating with the exhaust 52. The second air duct 62 is located above the inner liner 2, and has a second air inlet 6211 and a second air outlet 6221. The second air inlet 6211 is connected to the exhaust vent 52, and the second air duct 62 is connected to the cooking cavity 21. The first air outlet 6121 and the second air outlet 6221 are distributed horizontally, both facing forward, and both are directly opposite the air passage 31. The control panel 7 is located on the door 3 and is located directly in front of and above the first air outlet 6121.

[0051] In this built-in cooking device, the air blown out of the first air duct 61 passes through the control panel 7, while the air blown out of the second air duct 62 does not pass through the control panel 7. The water vapor generated during the steaming process is only discharged with the airflow from the second air duct 62. Therefore, no water vapor passes through the control panel 7, and no condensation forms, making it convenient for the user to operate the control panel 7.

[0052] For example, a built-in cooking appliance is a built-in steam oven / built-in steam oven / built-in microwave steam oven.

[0053] See Figure 2 and Figure 4The door body 3 is equipped with a cold air channel 32, which has a cold air inlet 321 and a cold air outlet 322. The cold air inlet 321 penetrates the bottom side of the door body 3, and the cold air outlet 322 penetrates the bottom wall of the air passage 31. The cold air outlet 322 is located directly below and close to the first air outlet 6121. On the one hand, outside cold air enters the door body 3 through the cold air inlet 321. After being heated, its density decreases, and it flows upward naturally, eventually leaving the door body 3 through the cold air outlet 322. This helps to dissipate heat from the door body 3 and prevents the door body 3 from burning the user. On the other hand, the air blown out from the first air outlet 6121 passes over the cold air outlet 322, where a negative pressure exists. This helps to accelerate the airflow within the cold air channel 32, further facilitating heat dissipation from the door body 3 and preventing the door body 3 from burning the user.

[0054] Because the second air duct 62 is connected to the cooking cavity 21, the air blown out from the second air outlet 6221 contains cooking fumes. (Comparison) Figure 2 and Figure 7 In order to prevent the air blown out from the second air outlet 6221 from polluting the inside of the door body 3, the second air outlet 6221 is set away from the cold air outlet 322.

[0055] contrast Figure 2 and Figure 7 The door body 3 is also equipped with an isolator 33, which separates the portion of the air passage 31 that faces the first air outlet 6121 from the portion that faces the second air outlet 6221. The cold air outlet 322 is located on the portion of the air passage 31 that faces the first air outlet 6121. This helps prevent the air blown out from the second air outlet 6221 from contaminating the interior of the door body 3.

[0056] See Figure 2 and Figure 5 The ventilation duct 31 includes a ventilation section 311 and a guide section 312. The guide section 312 extends gradually and widens from the rear end of the ventilation section 311. This guides the air blown out from the first air outlet 6121 and the second air outlet 6221 into the ventilation duct 31.

[0057] See Figure 7 There are two second air outlets 6221, which are located on both sides of the first air outlet 6121. In this way, the air containing water vapor in the second air duct 62 is discharged from the positions located on both sides of the first air outlet 6121, which helps to prevent excessive local moisture in the kitchen.

[0058] See Figure 6The cooking equipment also includes a water tank 8, which is positioned directly above and flush with the first air duct 61. This allows the water tank 8 to absorb heat from the first air duct 61, facilitating the air duct's function of dissipating heat from the cooking equipment. Furthermore, the water tank 8's temperature rises after absorbing heat from the first air duct 61, preheating the water. This means that when the water in the tank 8 is supplied to the steam generator 4 of the cooking equipment, it only needs to absorb less heat to evaporate into steam, saving energy and reducing the operating costs of the cooking equipment.

[0059] Within the first air duct 61, the temperature is higher closer to the first air outlet 6121. (See also...) Figure 6 The water tank 8 is positioned close to the first air outlet 6121. This facilitates the absorption of heat from the first air duct 61 by the water tank 8.

[0060] See Figure 7 In order to strengthen the first air duct 61, a reinforcing rib 613 is provided in the middle part of the first air outlet 6121. The reinforcing rib 613 connects the upper edge and the lower edge of the first air outlet 6121 together.

[0061] See Figure 7 The first air duct 61 consists of a front section 612 and a rear section 611, with the rear section 611 located behind the front section 612. The second air duct 62 consists of a front section 622 and a rear section 621, with the rear section 621 located behind the front section 622. The front section 612 and the front section 622 are distributed horizontally, while the rear section 611 and the rear section 621 are arranged side by side vertically, with the rear section 611 located above the rear section 621. This arrangement places the rear portion of the second air duct 62 relatively close to the inner liner 2, facilitating communication between the rear portion of the second air duct 62 and the cooking cavity 21.

[0062] See Figure 8 The second air duct 621 has multiple connection ports 6212. The cooking equipment also includes an exhaust pipe (not shown in the figure), which connects the second air duct 62 and the cooking chamber 21. The exhaust pipe has an air inlet and multiple air outlets, with each air outlet corresponding to a connection port 6212. The air inlet is connected to the cooking chamber 21, and each air outlet is connected to a corresponding connection port 6212.

[0063] Understandably, because the air inside the first air duct 61 does not contain high-temperature water vapor, the temperature inside the first air duct 61 is lower than the temperature inside the second air duct 62. In some embodiments, the first air duct 61 consists of a front section 612 and a rear section 611, with the rear section 611 located behind the front section 612; the second air duct 62 consists of a front section 622 and a rear section 621, with the rear section 621 located behind the front section 622; the front section 612 and the front section 622 are distributed horizontally, while the rear section 611 and the rear section 621 are arranged side by side vertically, with the rear section 611 located below the rear section 621. In this way, the first air duct 61 is relatively close to the inner liner 2, which is beneficial for utilizing the lower-temperature airflow within the first air duct 61 to dissipate heat from the structures near the inner liner 2.

[0064] It should be noted that, in this application, "directly above and directly in front" should be understood as the combined direction of "directly in front" and "directly above", and "directly below and directly in front" should be understood as the combined direction of "directly in front" and "directly below".

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
