[0062] In the related art, some ovens only have cooking functions, which are single in function and difficult to meet the diversified needs of users. Some ovens integrate other functions, such as ovens with electric water heater functions, fireplaces, etc., but still have certain technical problems, such as: electric ovens cannot completely meet the production needs of open fire roasting food; the flame propagation direction of gas ovens is usually fixed, resulting in uneven heating; the window of the oven door often affects user observation due to oil smoke attachment; the oven cannot completely replace the fireplace to provide warm air, etc.

[0063] Referring to Figure 1 to improve the above problems, embodiments of the present application provide a multifunctional oven 100, which can provide multiple function modes according to user needs, and improve user experience.

[0064] Continuing to refer to Figure 2 and Figure 3 , specifically, the multifunctional oven 100 includes a housing assembly 110, an open fire assembly 120, a steam assembly 130, and a control assembly. The housing assembly 110 has a working cavity 113, which can serve as a cooking space for food or a warm air generation space. The open fire assembly 120 includes a plurality of flame nozzles 121, each of which is disposed in the working cavity 113 and can spray flames into the working cavity 113 to heat food or air in the working cavity 113. The steam assembly 130 includes a plurality of steam nozzles 131, each of which is disposed in the working cavity 113 and can spray steam into the working cavity 113, thereby realizing a steaming mode for food or generating warm air with humidity. The control assembly is electrically connected to the open fire assembly 120 and the steam assembly 130, thereby controlling the working state of the open fire assembly 120 and the steam assembly 130 and realizing multiple working modes of the multifunctional oven 100.

[0065] For example, the control assembly includes a processing chip and an internal setting program, so that the user can select the corresponding working mode according to the needs, such as open fire cooking, open fire heating, no open fire cooking, no open fire heating, etc.

[0066] In some embodiments, the housing assembly 110 comprises a cabinet 111 and a cabinet door 112, the cabinet 111 is provided with a working cavity 113, and the cabinet door 112 is arranged on one side of the cabinet 111. Each flame nozzle 121 and each steam nozzle 131 are arranged on the side of the cabinet 111 close to the cabinet door 112 and are oppositely arranged in the direction of gravity.

[0067] Specifically, the multifunction oven 100 is in a single-door structure, one side of the cabinet door 112 is rotationally connected with the cabinet 111 to close or open the open side of the cabinet 111, and food is placed into the working cavity 113 through the opening. The flame nozzle 121 and the steam nozzle 131 are both located at the opening of the side of the cabinet 111 close to the cabinet door 112, and the flame nozzle 121 is located above the opening to be able to spray the flame from top to bottom, thereby improving the internal heating uniformity of the working cavity 113. The steam nozzle 131 is located below the opening, thereby facilitating the circulation and discharge of steam.

[0068] Further, the housing assembly 110 is also provided with a smoke outlet 114 and an air outlet 115, both of which are in communication with the working cavity 113 and can be controlled to be opened or closed.

[0069] Specifically, the smoke outlet 114 is arranged at the rear end of the cabinet 111, thereby discharging the smoke inside the working cavity 113 in the cooking mode. The air outlet 115 is arranged at the front end of the cabinet 111 to discharge warm air in the heating mode.

[0070] It should be noted that in the embodiments of the present application, the front end refers to the side of the multifunction oven 100 facing the user, i.e., the end provided with the cabinet door 112, and the rear end refers to the side of the multifunction oven 100 facing away from the user. It can be understood that the smoke outlet 114 and the air outlet 115 can be controlled in the opening and closing state by movable louvers or valves, which will not be described in detail here.

[0071] Further, the cabinet 111 is also provided with an air duct 116 and a filter 117, the air duct 116 is in communication with the smoke outlet 114, the air outlet 115 and the working cavity 113, and the filter 117 is arranged at the communication position of the air duct 116 and the working cavity 113.

[0072] Specifically, the air duct 116 is arranged above the working cavity 113 and is in communication with the smoke outlet 114 and the air outlet 115 at both ends. The bottom side of the air duct 116 is provided with a ventilation grille to communicate with the working cavity 113. The filter 117 is installed on the inner side of the air duct 116 and above the ventilation grille to filter the smoke generated inside the working cavity 113 and adsorb the oil smoke particles in the smoke.

[0073] Still further, the cabinet 111 is also provided with a fan 118, and the fan 118 is installed in the air duct 116.

[0074] Specifically, the fan 118 is installed at the middle part of the air duct 116, and in the powered state, the fan 118 can extract the gas in the working cavity 113 through the fan blade, and improve the exhaust efficiency of the smoke or the warm air. The exhaust rate of the smoke or the warm air can be adjusted by controlling the power of the fan 118.

[0075] In some embodiments, each flame nozzle 121 and each steam nozzle 131 are arranged on opposite sides of the shell assembly 110 and can rotate relative to the shell assembly 110.

[0076] Specifically, the flame nozzle 121 and the steam nozzle 131 can be controlled by an electric control system to adjust the angle, so as to adjust the jet direction of the flame and the steam to meet the uniform heating of the food during cooking.

[0077] Further, the open fire assembly 120 further comprises a first driving member 122 and a first spray pipe 123, the first driving member 122 is connected with one end of the first spray pipe 123 and can drive the first spray pipe 123 to rotate, and the first spray pipe 123 is equidistantly provided with each flame nozzle 121.

[0078] Specifically, the first driving member 122 comprises a rotary motor and a valve member, which can drive the first spray pipe 123 to rotate and deliver fuel gas into the first spray pipe 123 after being connected with the first spray pipe 123, so as to rotate the flame nozzle 121 fixed on the first spray pipe 123 and meet the continuous jet of the flame nozzle 121.

[0079] Further, the steam assembly 130 further comprises a second driving member 132 and a second spray pipe 133, the second driving member 132 is connected with one end of the second spray pipe 133 and can drive the second spray pipe 133 to rotate, and the second spray pipe 133 is equidistantly provided with each steam nozzle 131.

[0080] Specifically, the second driving member 132 comprises a rotary motor and a pump member, which can drive the second spray pipe 133 to rotate and deliver steam into the second spray pipe 133 after being connected with the second spray pipe 133, so as to rotate the steam nozzle 131 fixed on the second spray pipe 133 and continuously deliver steam to the steam nozzle 131, and then jet the steam into the working cavity 113 through the steam nozzle 131.

[0081] In some embodiments, the steam assembly 130 further comprises a steam pipeline 134 and a heating member 136, the steam pipeline 134 is in communication with the steam nozzle 131, and the heating member 136 can deliver heat to the steam pipeline 134 to generate steam in the steam pipeline 134.

[0082] Specifically, the steam pipe 134 and the heating element 136 are both installed in the box 111, and the heating element 136 is located at the side of the steam pipe 134 facing the inside of the working cavity 113, so as to facilitate the heating of the inside of the working cavity 113. At the same time, the heating element 136 can heat the steam pipe 134 to heat the water in the steam pipe 134 to generate steam, and the steam is delivered to the second nozzle 133 through the steam pipe 134, and finally sprayed to the working cavity 113 through the steam nozzle 131.

[0083] For example, in the specific embodiment, the steam pipe 134 and the heating element 136 are both provided with two, and each heating element 136 can heat a corresponding steam pipe 134. The heating element 136 can be an electric heating wire to generate heat in the energized state. The two heating elements 136 are oppositely arranged on the two sides of the box 111, so that the work can be heated at the same time, and the heating of the inside of the working cavity 113 is uniform. The two steam pipes 134 are also oppositely arranged on the two sides of the box 111, so as to facilitate the internal water circulation of the multifunctional oven 100 and improve the steam generation efficiency.

[0084] Further, the steam assembly 130 further comprises a water tank 135 connected with the steam pipe 134.

[0085] Specifically, the water tank 135 is arranged at the bottom side of the box 111, and the inside of the water tank 135 stores water source to deliver water to the steam pipe 134 for generating steam, and can also receive water from the inside of the steam pipe 134 to form internal water circulation.

[0086] Still further, the steam pipe 134 is also connected with an external container. In this way, the water in the steam pipe 134 is heated by the heating of the heating element 136, so as to deliver hot water to the external container, realizing the electric water heater function of the multifunctional oven 100. For example, the external container can be a water storage tank, a floor heating facility and the like which needs hot water.

[0087] Referring to Figure 4 and Figure 5 together, in some embodiments, the multifunctional oven 100 has a first working mode, which is a direct fire roasting mode. When the multifunctional oven 100 is in the first working mode:

[0088] The direct fire assembly 120 and the steam assembly 130 work at the same time, the smoke outlet 114 is opened, the air outlet 115 is closed, each flame nozzle 121 is inclined downward along the gravity direction to spray the flame toward the cooking area 119 of the working cavity 113, and each steam nozzle 131 sprays steam upward along the gravity direction to isolate the smoke from the box door 112.

[0089] Specifically, the user opens the oven door 112, places the food in the cooking zone 119 inside the oven body 111, and then closes the oven door 112. The user operates the switch button to start the multi-functional oven 100 and selects the appropriate operating mode according to their needs. When the user selects the cooking mode, the smoke vent 114 opens and the air vent 115 closes to allow smoke to be exhausted through the smoke vent 114 during cooking. Furthermore, the user can select the grilling mode, which uses open flame cooking via the open flame assembly 120. In this mode, the first drive unit 122 drives the flame nozzle 121 to rotate so that it pops out of the user's field of vision, while the second drive unit 132 drives the steam nozzle 131 to rotate, causing the steam nozzle 131 to spray gas, such as steam or fresh air, upwards. Thus, after the flame nozzle 121 is ignited, the flame will... Figure 5 The U-shaped flame propagation path allows the food to come into direct contact with the flame from both the top and bottom, and the direction of the flame can be continuously changed, resulting in more even heating. At the same time, because the steam nozzle 131 sprays fresh air along the inside of the cabinet door 112, the airflow isolates the oil fumes, reducing the oil fume adhesion rate of the cabinet door 112 and making it easier to clean.

[0090] Understandably, the cabinet door 112 is equipped with a transparent viewing window, which is isolated by the airflow of the steam nozzle 131 to prevent the viewing window from being blocked by oil fumes, making it convenient for users to observe and clean.

[0091] See also Figure 4 and Figure 6 As shown, in some embodiments, the multi-functional oven 100 has a second operating mode, which is a steam-bake mode. When the multi-functional oven 100 is in the second operating mode:

[0092] The steam assembly 130 operates independently, with the smoke outlet 114 open and the air outlet 115 closed. Each flame nozzle 121 is horizontally retracted inside the working chamber 113, and each steam nozzle 131 is tilted upward along the direction of gravity to spray steam toward the cooking zone 119 of the working chamber 113.

[0093] Specifically, similar to the first operating mode, the user selects the cooking mode, at which point the smoke vent 114 opens and the air vent 115 closes. Further, the user can select the steam-drying mode, i.e., steam cooking. In this mode, the flame nozzle 121 is horizontally positioned and hidden from the user's view. Then, under the action of the second drive unit 132, the steam nozzle 131 pops out, spraying steam upwards into the cooking zone 119 to deliver steam to the food and cook it. The steam can be directly sprayed onto the food, and the spray direction can be continuously changed, making the steaming process more uniform and efficient.

[0094] In addition, in this mode, the heating element can simultaneously provide auxiliary heating to the food, increasing the cooking speed.

[0095] See alsoFigure 4 and Figure 7 As shown in FIG. 1, in some embodiments, the multifunction oven 100 has a third operation mode, which is a warm air mode for delivering warm air to the room.

[0096] In one embodiment, the multifunction oven 100 can adopt a fire heating mode, in which the fire assembly 120 operates alone, and each flame nozzle 121 sprays flame downward along the direction of gravity towards the operation cavity 113 to heat the air in the operation cavity 113 and discharge warm air through the air outlet 115.

[0097] Specifically, after the multifunction oven 100 is started, the user can select a non-cooking mode, and then enter the warm air mode. The smoke outlet 114 is closed, and the air outlet 115 is opened to facilitate the provision of warm air to the room. Further, when the user selects the fire heating mode, the first driving member 122 controls the flame nozzle 121 to spray flame at an angle downward, heat the air in the operation cavity 113, and blow out through the air outlet 115 under the suction of the fan 118. In this way, the multifunction oven 100 can realize the function of a fireplace, and because the flame propagates from top to bottom, the operation cavity 113 is heated more uniformly, and the service life of the box body 111 is higher.

[0098] In another embodiment, the multifunction oven 100 can adopt a non-fire heating mode, in which the steam assembly 130 operates alone, the smoke outlet 114 is closed, the air outlet 115 is opened, and the heating member 136 is started to heat the air in the operation cavity 113 and discharge warm air through the air outlet 115.

[0099] Specifically, after the multifunction oven 100 is started, the user can select a non-cooking mode, and then enter the warm air mode. The smoke outlet 114 is closed, and the air outlet 115 is opened. Further, when the user selects the non-fire heating mode. At this time, the heating member 136 is started to heat the air in the operation cavity 113, and under the driving of the fan 118, the warm air is delivered to the room.

[0100] In some embodiments, the multifunction oven 100 can also perform humidification or hot water supply while only heating. That is, on the basis of the third operation mode, the steam assembly 130 operates to supplement steam to the warm air, or discharge hot water in the steam pipeline 134 to an external container.

[0101] In one embodiment, when the multifunction oven 100 selects fire heating and the room is relatively dry, the heating member and the steam nozzle 131 can be started synchronously. The heating member 136 heats the water in the steam pipeline 134 to form steam, which is sprayed into the operation cavity 113 through the steam nozzle 131, so that the steam is mixed in the warm air, and finally discharged to the room.

[0102] In another embodiment, when the multifunction oven 100 selects non-open fire heating and the indoor is relatively dry, the steam nozzle 131 is opened to spray steam generated by the heating element 136 in the steam pipeline 134 into the working cavity 113, so that the steam is mixed in the warm air.

[0103] Further, the steam assembly 130 further comprises a water temperature sensor to monitor the water temperature in the steam pipeline 134, so as to control the power of the heating element 136 and adjust the delivery rate of the steam.

[0104] In another embodiment, when the multifunction oven 100 selects open fire heating and needs to provide hot water outside, the heating element can be started according to the water temperature in the steam pipeline 134. If the water temperature is higher than a threshold value, the hot water can be directly discharged through the steam pipeline 134 through a valve. If the water temperature is lower than the threshold value, the heating element 136 is started synchronously to heat the water in the steam pipeline 134 until the threshold value is reached, and the heating element 136 stops working.

[0105] In another embodiment, when the multifunction oven 100 selects non-open fire heating and needs to provide hot water outside, the heating element 136 synchronously performs air heating in the working cavity 113 and water heating in the steam pipeline 134. The working principle is the same as the previous embodiment, which is not repeated here.

[0106] In some embodiments, the multifunction oven 100 has a fifth working mode, which is a self-cleaning mode to clean the filter 117. When the multifunction oven 100 is in the fifth working mode, the flame nozzle 121 sprays flame along the horizontal direction to the filter 117 to heat the filter 117 to dissolve the oil stains attached to the surface of the filter 117.

[0107] It can be understood that the filter 117 can include a filter grid in a grid shape, so as to adhere to the tobacco tar particles in the smoke during cooking. Therefore, the filter 117 can be directly heated by the flame nozzle 121, so that the oil stains attached to the surface of the filter 117 are dissolved under the heating condition, so that the oil stains can flow and be collected, realizing automatic cleaning of the filter 117.

[0108] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present disclosure.

[0109] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
