Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen utensils, in particular to a steaming oven and a steaming oven integrated with a stove. BACKGROUND

[0002] In order to achieve better cooking effect, the steaming oven needs to have a dehumidification function, which timely discharges the moisture in the cooking cavity in the baking function mode to quickly discharge the internal moisture of the food, and quickly discharges the water vapor in the cooking cavity before reminding the user of the completion of cooking in the steaming function mode to prevent the user from being splashed with steam when opening the door. The traditional steaming oven uses a centrifugal fan to realize the dehumidification function. Specifically, a dehumidification channel communicating with the cooking cavity and an exhaust pipe communicating the cooking cavity with the outside are arranged on the steaming oven, and the centrifugal fan introduces dry air outside the inner container into the cooking cavity of the inner container through the dehumidification channel, thereby accelerating the discharge of the moisture in the cooking cavity to the outside through the exhaust pipe. In these steaming ovens, in order to prevent the water vapor in the cooking cavity from overflowing through the dehumidification channel and causing the electrical elements near the dehumidification channel to fail, an electromagnetic valve is arranged on the dehumidification channel to control the opening and closing of the dehumidification channel. However, the introduction of the electromagnetic valve increases the cost of the steaming oven and makes the electrical control of the steaming oven more complex. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a steaming oven and a steaming oven integrated with a stove aiming at the above problems.

[0004] In order to solve the above problems, the present application provides the technical solutions as follows:

[0005] A steaming oven, comprising:

[0006] a box body;

[0007] an inner container fixedly arranged in the box body, an inner wall of the inner container surrounding a cooking cavity, the inner container being provided with an air inlet hole and an air outlet hole;

[0008] a diaphragm type air pump located outside the inner container, the diaphragm type air pump having a first air inlet and a first air outlet, the first air inlet being in communication with the outside, the first air outlet, the air inlet hole and the cooking cavity being in communication in sequence; and

[0009] an exhaust pipe, the cooking cavity, the air outlet hole and the exhaust pipe being in communication in sequence.

[0010] The steaming oven has at least the following beneficial effects:

[0011] This steam oven utilizes a diaphragm-type air pump to achieve dehumidification. Specifically, when the diaphragm-type air pump is working, dry air from outside the inner cavity enters the cooking chamber sequentially through the first air inlet, the first air outlet, and the air intake hole, thereby accelerating the expulsion of moisture from the cooking chamber to the outside through the air outlet and the exhaust pipe. Because the diaphragm-type air pump prevents backflow (i.e., gas can only enter through the first air inlet and exit through the first air outlet, and cannot enter through the first air outlet), water vapor in the cooking chamber cannot overflow through the air inlet and the first air outlet. Therefore, this steam oven does not require a solenoid valve, which reduces the cost of the steam oven and simplifies its electrical control.

[0012] In one embodiment, the steam oven further includes a silicone rubber support fixed to the oven body, and the diaphragm air pump is fixed to the silicone rubber support.

[0013] This design allows the silicone rubber bracket to reduce the noise generated by the diaphragm air pump, thus improving the user experience.

[0014] In one embodiment, the diaphragm air pump is spaced apart from the housing.

[0015] This design helps reduce the noise generated by the diaphragm air pump and improves the user experience.

[0016] In one embodiment, the steam oven further includes a high-temperature resistant silicone rubber hose, through which the first steam outlet and the cooking cavity are connected.

[0017] With this configuration, the silicone rubber hose becomes a flexible tube, easy to bend and install, adaptable to complex pipeline layouts, and convenient for the installation and maintenance of diaphragm air pumps.

[0018] In one embodiment, the inner liner is provided with a plurality of air inlets, and the silicone rubber hose has a second air inlet and a plurality of second air outlets. The second air inlet is connected to the first air outlet, and the second air outlet is configured to correspond one-to-one with the air inlet. Each second air outlet is connected to the corresponding air inlet.

[0019] With this design, relatively cool and dry air from outside the inner cavity enters the cooking cavity from multiple points, effectively dispersing the air flowing into the cooking cavity from the outside. This reduces the interference of outside air entering the cooking cavity with the heat field inside the cooking cavity, which helps to ensure the cooking effect of the steam oven.

[0020] In one embodiment, the inner liner is provided with only four air inlets, which are evenly distributed on the back wall of the inner liner and located at the four corners of the back wall of the inner liner.

[0021] This design can evenly disperse the air flowing into the cooking cavity from the outside, which helps to reduce the interference of outside air entering the cooking cavity with the heat field inside the cooking cavity, and helps to ensure the cooking effect of the steam oven.

[0022] In one embodiment, the air inlet is a circular hole with a diameter of D, where D ≤ 6 mm.

[0023] With this design, the air intake vent has a smaller area, and the airflow entering the cooking cavity from the air intake vent is a small stream of air. This helps to reduce the interference of outside air entering the cooking cavity with the heat field inside the cooking cavity, and helps to ensure the cooking effect of the steam oven.

[0024] In one embodiment, the diaphragm air pump is located above the cooking chamber.

[0025] With this configuration, even when the diaphragm air pump is not in operation (including the state before the diaphragm air pump starts working and the state after the diaphragm air pump stops working), condensation will not easily accumulate inside the silicone rubber hose due to gravity.

[0026] In one embodiment, the steam oven has a circuit board, and the diaphragm air pump is disposed near the circuit board.

[0027] This configuration allows the diaphragm air pump to create a rapid airflow near the circuit board during operation, which helps dissipate heat from the circuit board and ensures its reliable operation.

[0028] This application also provides a combination cooktop, steam oven, and grill, which includes:

[0029] A cooktop includes a heat dissipation duct and a heat dissipation fan disposed in the heat dissipation duct. The heat dissipation duct has a third air inlet and a third air outlet, the third air outlet being connected to the outside. The heat dissipation fan is used to generate an airflow from the third air inlet to the third air outlet.

[0030] In the aforementioned steam oven, the exhaust pipe is connected to the heat dissipation duct.

[0031] This steam oven combination appliance has at least the following beneficial effects:

[0032] In this steam oven, the steam oven utilizes a diaphragm-type air pump to achieve dehumidification. Specifically, when the diaphragm-type air pump is working, dry air from outside the inner cavity enters the cooking chamber sequentially through the first air inlet, the first air outlet, and the air intake hole. This accelerates the expulsion of moisture from the cooking chamber to the outside through the air outlet, exhaust pipe, and heat dissipation duct. Because the diaphragm-type air pump prevents backflow (i.e., gas can only enter through the first air inlet and exit through the first air outlet, and cannot enter through the first air outlet), water vapor in the cooking chamber cannot overflow through the air inlet and the first air outlet. Therefore, the steam oven in this steam oven does not require a solenoid valve, which reduces the cost of the steam oven and simplifies its electrical control. Attached Figure Description

[0049] See Figures 1 to 6 This application first provides a steam oven 1, which includes a housing 11, an inner liner 12, a diaphragm air pump 13, and an exhaust pipe 14. The inner liner 12 is fixed to the housing 11, and the inner wall of the inner liner 12 encloses a cooking cavity 121. The inner liner 12 is provided with an air inlet 122 and an air outlet 123. The diaphragm air pump 13 is located outside the inner liner 12. The diaphragm air pump 13 has a first air inlet 131 and a first air outlet 132. The first air inlet 131 is connected to the outside. The first air outlet 132, the air inlet 122, and the cooking cavity 121 are connected in sequence. The cooking cavity 121, the air outlet 123, and the exhaust pipe 14 are connected in sequence.

[0050] The steam oven 1 has at least the following beneficial effects:

[0051] The steam oven 1 utilizes a diaphragm-type air pump 13 to achieve dehumidification. Specifically, when the diaphragm-type air pump 13 is working, dry air outside the inner cavity 12 enters the cooking cavity 121 sequentially through the first air inlet 131, the first air outlet 132, and the air inlet 122, thereby accelerating the discharge of moisture in the cooking cavity 121 to the outside through the air outlet 123 and the exhaust pipe 14. Because the diaphragm-type air pump 13 can prevent gas backflow (i.e., gas can only enter from the first air inlet 131 and exit from the first air outlet 132, and cannot enter from the first air outlet 132), water vapor in the cooking cavity 121 cannot overflow through the air inlet 122 and the first air outlet 132. Therefore, the steam oven 1 does not require the introduction of a solenoid valve, which makes the cost of the steam oven 1 lower and the electrical control of the steam oven 1 simpler.

[0052] SeeFigures 3 to 6 The steam oven 1 also includes a silicone rubber support 15, which is fixed to the oven body 11, and the diaphragm air pump 13 is fixed to the silicone rubber support 15. The silicone rubber support 15 can reduce the noise generated by the diaphragm air pump 13 during operation, which is beneficial to improving the user experience.

[0053] See Figure 5 The diaphragm air pump 13 is spaced apart from the housing 11, meaning that no part of the diaphragm air pump 13 directly contacts the housing 11. This helps reduce the noise generated by the diaphragm air pump 13 during operation and improves the user experience.

[0054] Preferably, the steam oven 1 also includes a high-temperature resistant silicone rubber hose, through which the first air outlet 132 and the cooking cavity 121 are connected. The silicone rubber hose is a flexible tube, easy to bend and install, and can adapt to complex pipeline layouts, facilitating the installation and maintenance of the diaphragm air pump 13.

[0055] In other embodiments, the first vent 132 and the cooking cavity 121 may also be connected by a tube made of a rigid body (e.g., stainless steel).

[0056] In some embodiments, the inner liner 12 is provided with a plurality of air inlets 122, and the silicone rubber hose has a second air inlet and a plurality of second air outlets; in other words, the silicone rubber hose is a multi-port hose. The second air inlet is connected to the first air outlet 132, and the second air outlets are arranged in a one-to-one correspondence with the air inlets 122, with each second air outlet connected to the corresponding air inlet 122. In this way, relatively cool and dry air from outside the inner liner 12 enters the cooking cavity 121 from multiple points, thereby effectively dispersing the air flowing into the cooking cavity 121 from the outside, reducing the interference of outside air entering the cooking cavity 121 on the internal heat field, and helping to ensure the cooking effect of the steam oven 1.

[0057] Preferably, the inner cavity 12 is provided with only four air inlets 122, which are evenly distributed on the back wall of the inner cavity 12 and located at the four corners of the back wall of the inner cavity 12. In this way, the air flowing into the cooking cavity 121 from the outside can be evenly distributed, which helps to reduce the interference of outside air entering the cooking cavity 121 on the internal heat field of the cooking cavity 121, and helps to ensure the cooking effect of the steam oven 1.

[0058] See Figure 5 The air inlet 122 is a circular hole with a diameter of D, where D ≤ 6 mm. This results in a smaller area for the air inlet 122, leading to a smaller airflow into the cooking cavity 121. This reduces the interference of outside air entering the cooking cavity 121 with the internal heat field, thus ensuring the optimal cooking effect of the steam oven 1.

[0059] SeeFigure 3 The diaphragm air pump 13 is located above the cooking cavity 121. In this way, when the diaphragm air pump 13 is not working (including the state where the diaphragm air pump 13 has not yet started working and the state where the diaphragm air pump 13 has stopped working after working), due to the effect of gravity, condensation is not easily accumulated inside the silicone rubber hose.

[0060] In some embodiments, the steam oven 1 has a circuit board, and a diaphragm air pump 13 is disposed close to the circuit board. In this way, the diaphragm air pump 13 creates a fast-flowing airflow near the circuit board during operation, which is beneficial for heat dissipation of the circuit board and helps ensure reliable operation of the circuit board.

[0061] See Figures 1 to 8 This application further provides a combination cooktop, steam oven, and oven, comprising a cooktop 2 and the aforementioned steam oven 1. The cooktop 2 includes a heat dissipation duct 21 and a heat dissipation fan 22 disposed within the heat dissipation duct 21. The heat dissipation duct 21 has a third air inlet 211 and a third air outlet 212, the third air outlet 212 being connected to the outside. The heat dissipation fan 22 is used to generate airflow from the third air inlet 211 to the third air outlet 212. An exhaust pipe 14 is connected to the heat dissipation duct 21.

[0062] This steam oven combination appliance has at least the following beneficial effects:

[0063] In this steam oven, the steam oven 1 utilizes a diaphragm-type air pump 13 to achieve dehumidification. Specifically, when the diaphragm-type air pump 13 is working, dry air outside the inner cavity 12 enters the cooking cavity 121 sequentially through the first air inlet 131, the first air outlet 132, and the air inlet hole 122, thereby accelerating the discharge of moisture in the cooking cavity 121 to the outside through the air outlet hole 123, the exhaust pipe 14, and the heat dissipation duct 21. Because the diaphragm-type air pump 13 can prevent gas backflow (i.e., gas can only enter from the first air inlet 131 and exit from the first air outlet 132, and cannot enter from the first air outlet 132), water vapor in the cooking cavity 121 cannot overflow through the air inlet hole 122 and the first air outlet 132. Therefore, the steam oven 1 in this steam oven does not need to be equipped with a solenoid valve, which makes the cost of the steam oven 1 lower and the electrical control of the steam oven 1 simpler.

[0064] 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.

[0065] 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.
