Description

Technical Field

[0001] The invention relates to the technical field of ovens, in particular to a double-compartment oven. Background Art

[0002] The oven is one of the more common electrical appliances currently, which mainly uses the radiant heat emitted by electric heating elements to process food.

[0003] The basic structure of an existing oven generally consists of an oven body, an oven door, an oven cavity, an electric heating element, and a controller for controlling the electric heating element. When heating food, the food is placed in the oven cavity. After the oven door is closed, the electric heating element is controlled to generate heat by pressing a button on the controller to heat the food in the oven cavity. Since the existing oven has only one oven cavity, when baking a variety of foods, each food is longitudinally spaced and baked on a baking tray. However, although different foods are placed in layers on the baking tray, it is still impossible to avoid the food from odor-smelling each other, which affects the edibility of the food.

[0004] Secondly, in order to increase the practicality, the current ovens generally add an air intake component (circulation fan component) to switch the oven to an air fryer. However, the existing ovens cannot achieve the perfect results of the two functions of oven and air fryer, which is mainly reflected in:

[0005] In order to ensure the baking effect, the oven is required to be used in a sealed oven cavity (baking chamber) to prevent heat loss; when used as an air fryer, the sealed oven cavity will affect the outward transmission of water vapor from the food, thus affecting the use of the air fryer state. Therefore, it is impossible to take into account the use of both oven and air fryer modes.

[0006] In summary, the existing oven needs to be improved to solve the technical problem of the present invention. Summary of the invention

[0056] The present invention has at least the following beneficial effects:

[0057] 1. The oven cavity of the oven of the present invention can be divided into two independent compartments by a high temperature resistant rolled cloth, so different types of food can be baked to avoid the phenomenon of odor mixing and ensure the edibility of the food.

[0058] 1.1 The formation of the compartments of the present invention is achieved by controlling the high temperature resistant cloth by the first winding part and the second winding part of the present invention. That is to say, when forming the compartments, the first winding part and the second winding part cooperate with each other to make the high temperature resistant cloth unfold and lie across the furnace cavity, thereby dividing the furnace cavity into two independent compartments for use.

[0059] 2. For the convenience of cleaning, the present invention can remove the high temperature resistant cloth from the oven by disassembling the first winding part and the second winding part for independent cleaning.

[0060] 3. The oven of the present invention also takes into account the use of an air fryer, that is, an air induced structure is provided on the box body of the present invention, and the air induced structure is used to introduce air flow into the oven cavity, and cooperates with the heating element to form circulating air, so as to "air fry" the food in the oven cavity, thereby realizing the use of the air fryer.

[0061] 4. In order to make the present invention be better used between the two modes of oven and air fryer, a rotating frame and an air filter structure are provided in the present invention. In the oven mode, the rotating frame rotates so that the connecting port and the first air outlet are misaligned with each other, and the air inlet is closed by the filter structure, so that the oven cavity is closed, avoiding heat loss in the oven mode and ensuring use; while in the air fryer mode, the rotating frame rotates so that the connecting port and the first air outlet correspond to each other, and the filter structure opens the air inlet, and the air induced structure can introduce the airflow from the air inlet into the oven cavity and form hot air after passing through the heating element, and the hot air is discharged from the second air outlet after passing through the food in the oven cavity, completing the hot air cycle so as to be able to take the generated water vapor away from the oven cavity.

[0062] 5. Due to the addition of the air fryer mode, long-term use will cause dust and other impurities to accumulate in the oven. In order to ensure hygienic cooking of food, it is also necessary to clean the flow branches of the airflow (especially the air inlet branches). The oven of the present invention has added a self-cleaning function (this can avoid frequent disassembly of the entire oven, and at the same time can also meet the cleaning standards) to clean the columnar filter at the air inlet (the key position for the airflow to enter the oven cavity). During cleaning, the air filter structure closes the air inlet, and impurities are discharged from the pressure relief port, thereby preventing impurities from entering the oven cavity.

[0063] 5.1 During cleaning, the present invention utilizes the induced draft structure to drive the synchronous wheel and drive the lifting body to rotate, and utilizes the rotation of the lifting body to clean the columnar filter screen, while cooperating with the gas introduced by the induced draft structure to discharge the impurities in the filter cavity.

[0064] 6. In order to further enhance the air filtering effect, the present invention sets a filter in the air induction chamber. The filter can be used for the first filtering, while the columnar filter is used for the second filtering. The two filterings can ensure that the airflow entering the oven cavity meets the food processing standard.

[0065] 6.1 The present invention is also very convenient for cleaning the filter screen. The filter screen can be removed and cleaned by removing the top cover.

[0066] In addition, other advantages of the present invention will be shown in the embodiment of the present invention, thereby making the beneficial effects of the present invention more significant. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] refer to Figure 1-Figure 9 , this embodiment has at least the following usage principles:

[0106] 1. Installation and removal principle of winding roller: reference Figure 4-Figure 7During installation, the first U-shaped plate and the second U-shaped plate are assembled and the high-temperature resistant cloth is located in the movable opening. Subsequently, the outer shaft and the inner shaft of each winding roller are contracted, and each winding roller is placed in the installation cavity of each column from the disassembly opening. At the same time, the limiting cavity of the plug-in shaft body located at the end of the inner shaft and the outer shaft of the winding roller is matched with the limiting chuck (through the side ribs and the side grooves). After the limiting cavity and the limiting chuck are matched, the winding roller is released, and the inner shaft and the outer shaft are driven to reset by the telescopic spring and matched with the clamping shaft and the driving shaft to complete the installation of the winding roller. Finally, the installation plate obtained by assembling the first U-shaped plate and the second U-shaped plate is slid toward each column respectively until the installation plate and the disassembly opening are completed (that is, each U-shaped plate is contracted, and the plug-in block at the end of the U-shaped plate is matched with the plug-in groove at the disassembly opening to complete the installation).

[0107] 2. Principle of formation and elimination of compartments: When forming compartments, the controller drives the PLC motor to rotate the drive shaft and makes the winding rollers cooperate (one winding roller winds and the other winding roller unwinds, the same below) to complete the unwinding of the high-temperature resistant cloth, so that the high-temperature resistant cloth lies across the rotating frame, thereby dividing the furnace cavity into two compartments for baking different foods; when eliminating compartments, the PLC motor rotates the drive shaft and makes the winding rollers cooperate to rewind the high-temperature resistant cloth, so that the high-temperature resistant cloth is rewound by the winding roller and enters the installation cavity, thereby eliminating the compartments, and the slide grooves set on the top plate and bottom plate of the rotating frame can allow the high-temperature resistant cloth to move, which can better separate the furnace cavity and form compartments.

[0108] When this embodiment is in use, it can be determined whether isolated baking is required based on the type of food. During isolated baking, different foods are placed in different compartments so that there is no odor contamination during processing, thereby ensuring normal consumption of the food.

[0136] This embodiment has at least the following usage principles:

[0137] 1. Switching principle between oven and air fryer: reference Figure 2-Figure 3 as well as Figure 12-13 In this embodiment, when used as an oven, after putting food into the oven cavity, the rotating frame is rotated so that the connection port on the bottom plate is misaligned with the first exhaust port, and at the same time, the electromagnet is powered off, and the lifting body is controlled by the support spring to rise and enter the recessed cavity, and at the same time, the lifting shaft drives the flow divider to close the air inlet, so that the oven cavity is relatively closed, thereby preventing heat from being lost when the oven is started; when used as an air fryer, after putting food into the oven cavity, the rotating frame is rotated so that the connection port on the bottom plate corresponds to the second exhaust port, and at the same time, the electromagnet is powered on, and the lifting body is sucked The induction cavity leaves, and the flow divider opens the air inlet at this time. When the driving motor starts and controls the fan to start, the air flow is introduced from the external air inlet into the positioning cavity, and enters the air induction cavity after being filtered by the filter screen. The air flow enters the filter cavity from the first inlet wind on the lifting body, and then is sent into the furnace cavity from the air inlet after being filtered by the columnar filter screen. The air flow entering the furnace cavity passes through the installation port of the top plate and is heated by the upper heating tube. After passing through the food, the air flow enters the exhaust cavity from the second exhaust ports on both sides of the bottom plate slide slot, and finally is discharged from the furnace cavity through the connecting port and the second exhaust port, completing the processing of the food.

[0138] 1.1 When used as an air fryer, the airflow can be diverted by the diverter after entering the air inlet, so that the hot air can better contact the food;

[0139] 1.2 When used as an air fryer, when the oven cavity is divided into two compartments by the high temperature resistant cloth, the airflow is still sent into each compartment through the air inlet, and since the second exhaust ports on the two side walls of the chute are respectively located at each compartment, the hot air in each compartment enters the exhaust cavity through the second exhaust ports on both sides of the chute and is smoothly discharged from the oven cavity.

[0140] 2. Cleaning principle: reference Figure 1-Figure 3 as well as Fig.12 In this embodiment, when cleaning, the top cover can be disassembled, and the filter screen can be removed for independent cleaning. After cleaning, the filter screen and the top cover can be reinstalled;

[0141] The cleaning of the filter structure in this embodiment mainly involves: Figure 12-13When cleaning, the electromagnet is powered off, the lifting body is lifted, and the air inlet is closed by diversion. When the fan is started and the airflow is introduced, the airflow enters the filter chamber from the second air inlet formed by the lifting body and the bottom of the air inlet chamber, and leaves from the first air inlet of the lifting body, and passes through the pressure relief chamber until it is discharged through the pressure relief port. When the pressure in the pressure relief chamber increases, the air pressure will push the pressure relief port open, so that the pressure relief port is opened, thereby completing the dust removal;

[0142] During the above cleaning process, the lifting body rises and makes the chuck and the adapting groove (the cooperation between the chuck and the adapting groove is the same as the side ribs and side grooves in Example 1, and the specific structure can be referred to Figure 8 ), therefore, when the fan is started, the second wheel body is driven to rotate through the first wheel body, and the various lifting bodies are driven to rotate through the second wheel body. When the lifting body rotates, the columnar filter is cleaned by the cleaning brush bar, and the impurities on the columnar filter can be drawn out of the pressure relief chamber by the airflow entering from the second inlet to complete the cleaning.

[0143] 2.1 When the lifting body rotates, the cleaning brush bar will guide the airflow in the filter chamber to move around the columnar filter, thereby improving the cleaning effect of the columnar filter. The positioning connection port provided on the top cover of this embodiment not only plays a positioning role when installing the top cover, but also can be connected to the pipeline of the external exhaust device when cleaning the columnar filter. Therefore, when cleaning the columnar filter, the air intake of the fan and the exhaust of the external exhaust device can increase the cleaning intensity of the columnar filter to improve the cleaning effect.

[0144] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
