Description

Technical Field

[0001] This application relates to the field of household appliances, and more specifically, to a cooking appliance. Background Technology

[0002] As a common kitchen appliance, a steam oven mainly consists of a control panel, heating elements, an evaporator, and a fan. When cooking food, the food is placed on racks of different heights using containers such as baking trays. The operating parameters are then set via the control panel to activate the corresponding heating elements, allowing the cavity to reach the desired temperature for optimal cooking results.

[0003] The baking temperature range of steam ovens is generally between 35℃ and 250℃, and this temperature is usually tested at the geometric center of the steam oven. However, some cooking requires temperatures higher than 250℃, such as 280℃ or a baking function above 300℃, in order to achieve the desired crispy and well-colored food.

[0004] To achieve the desired high-temperature cooking effect, the number or power of heating elements is typically increased to obtain a more efficient heating effect, thus meeting the high-temperature cooking requirements of a steam oven. However, this method has the following drawbacks: First, increasing the number or power of heating elements can cause the overall power of the appliance to exceed the power limit of household appliances. Second, achieving high-temperature cooking by increasing the number or power of heating elements may cause the steam oven to overheat significantly, with the surface temperature of the entire appliance exceeding the standard, posing a risk of burns.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] The cooking appliance provided in this embodiment includes a cooking chamber 100, a heat source component 200, a support member, and a drive component 300. The support member is used to carry food and is detachably installed in the cooking chamber 100. The heat source component 200 is located in the cooking chamber 100 and is disposed opposite to the support member. The drive component 300 is installed on the outer wall of the cooking chamber 100 and extends into the cooking chamber 100 to be connected to the heat source component 200 for transmission, so as to drive the heat source component 200 to move towards or away from the support member.

[0043] Specifically, the heat source assembly 200 is used to convert electrical energy into heat to cook food mounted on the carrier. See also Figure 1 and Figure 4 The cooking appliance includes a housing 110 with an opening and a door 120 hinged to the opening end of the housing 110. The door 120 controls the opening and closing of the housing 110. When the door 120 is closed, the housing 110 and the door 120 enclose a cooking chamber 100. The door 120 is hinged to the opening end of the housing 110, facilitating the installation and removal of the support components. Furthermore, the support components overlap or snap into the cooking chamber 100.

[0044] This cooking appliance is a cooking appliance with a baking function, including but not limited to a steam oven. A support component is installed inside the cooking chamber 100. The support component is used to place food, enabling the cooking appliance to cook the food. The support component is detachably connected to the cooking chamber 100, facilitating disassembly and assembly for easy cleaning. The support component includes, but is not limited to, shelves or baking trays, and its material is not limited; the support component can also be designed as a heatable container bag. A heat source component 200 is located inside the cooking chamber 100, enabling the cooking appliance to heat up. The heat source component 200 is positioned opposite the support component, enabling it to heat the food placed on the support component. A drive component 300 is installed on the outer wall of the cooking chamber 100, providing support and fixation for the drive component 300. The drive component 300 is connected to the heat source component 200, providing power to the heat source component 200, thereby adjusting the distance between the heat source component 200 and the support component. Based on the common sense that the closer to the heating element, the higher the temperature, the heat source component 200 automatically moves closer to the food during cooking, driven by the drive component 300, to bring the food to a higher temperature. This cooking appliance can achieve high-temperature cooking without changing the number and power of the original heating elements 220, thus improving the safety of the cooking appliance.

[0045] The following is a detailed description of the structure and shape of cooking utensils:

[0046] In the optional embodiments of this utility model, see Figure 1 and Figure 4 The drive assembly 300 is mounted on the top of the cooking chamber 100, and the heat source assembly 200 is located above the support member along the height direction of the cooking chamber 100.

[0047] Specifically, the drive assembly 300 is located above the housing 110 and passes through the side wall of the housing 110 to connect with the heat source assembly 200, so as to drive the heat source assembly 200 to move in the vertical direction.

[0048] The drive assembly 300 is mounted on top of the cooking chamber 100 to prevent it from interfering with the installation of parts below the cooking chamber 100. The heat source assembly 200 is located above the support member to facilitate heating of food above the support member and to facilitate the connection between the heat source assembly 200 and the drive assembly 300, preventing the support member from obstructing the connection between the heat source assembly 200 and the drive assembly 300.

[0049] In the optional embodiments of this utility model, see Figure 1 and Figure 2The drive assembly 300 includes a drive member 310 and a movable slide rail 320. The drive member 310 is mounted on the top of the cooking chamber 100. One end of the movable slide rail 320 is connected to the drive member 310 for transmission, and the other end extends into the cooking chamber 100 and is connected to the heat source assembly 200.

[0050] Specifically, the movable slide rail 320 is strip-shaped, and its length is arranged along the height direction of the cooking chamber 100. Furthermore, the heat source component 200 is snapped into the movable slide rail 320, allowing for a detachable connection. This facilitates the assembly of the cooking appliance by first installing the movable slide rail 320 onto the housing 110, and then installing the heat source component 200 onto the movable slide rail 320. Of course, a fixed connection between the heat source component 200 and the movable slide rail 320, such as welding, should also be within the scope of protection of this embodiment. Preferably, the drive component 310 is an electric motor; however, other drive devices used for the drive component 310 should also be within the scope of protection of this embodiment.

[0051] An electric motor drives the sliding rail 320 to move up and down, which in turn drives the heat source component 200 to move up and down, allowing the heat source component 200 to move closer to or further away from the support.

[0052] In an optional embodiment of this utility model, two movable slide rails 320 are provided. Both movable slide rails 320 are connected to the drive component 310 and are respectively connected to both ends of the heat source component 200.

[0053] Specifically, the cabinet 110 is square, and two movable slide rails 320 are spaced apart along the length of the cabinet 110. Furthermore, a sealing element is sandwiched between the movable slide rails 320 and the cabinet 110 to prevent the loss of steam or heat from the cooking chamber 100.

[0054] Two movable slide rails 320 are provided, and the two movable slide rails 320 are respectively connected to the two ends of the heat source component 200, so as to drive the two ends of the heat source component 200 simultaneously, thereby avoiding the problem of unstable heat control when the heat source component 200 moves.

[0055] In an optional embodiment of this utility model, the drive assembly 300 further includes a fixed track 330, which is installed on the inner wall of the cooking chamber 100 and has a groove extending along the height direction of the cooking chamber 100; the movable slide rail 320 is slidably engaged with the groove.

[0056] Specifically, both movable slide rails 320 are equipped with fixed rails 330.

[0057] The fixed track 330 and the movable slide rail 320 slide in a sliding fit. The fixed track 330 guides the movement direction of the movable slide rail 320 and prevents the movable slide rail 320 from deviating and causing instability during movement.

[0058] In an optional embodiment of this utility model, the drive assembly 300 further includes a transmission group 340, a transmission shaft 350, and two drive gears 360; the input end of the transmission group 340 is connected to the drive member 310, and the output end is mounted on the transmission shaft 350; both ends of the transmission shaft 350 are respectively connected to the two drive gears 360, and the two drive gears 360 respectively mesh with the two moving slide rails 320.

[0059] Specifically, the drive component 310 drives the drive shaft 350 to rotate via the transmission assembly 340. The drive shaft 350 drives the drive gear 360 to rotate, and the rotation of the drive gear 360 causes the movable slide rail 320 to move. The forward and reverse rotation of the drive component 310 can respectively realize the raising and lowering of the movable slide rail 320. The function of the transmission assembly 340 and the drive shaft 350 is to ensure that the two movable slide rails 320 move in the same direction while using a single drive component 310, thus preventing the heat source assembly 200 from tilting.

[0060] The drive gear 360 meshes with the movable slide rail 320, enabling the drive assembly 300 to drive the movable slide rail 320 to rise or fall.

[0061] In one implementation, the drive gear 360 is mounted at both ends of the transmission shaft 350, and the sidewall of the movable slide rail 320 meshes with the drive gear 360.

[0062] As another implementation method, see Figure 2 The drive assembly 300 also includes two reversing gear sets 370, which are respectively mounted on both ends of the drive shaft 350. The reversing gear sets 370 include a first bevel gear 371 and a second bevel gear 372 that mesh with each other. The first bevel gear 371 is mounted on the drive shaft 350, and the second bevel gear 372 is connected to the drive gear 360.

[0063] Specifically, both the second bevel gear 372 and the drive gear 360 are mounted on the fixed shaft 380. The axis of the fixed shaft 380 is on the same horizontal plane as the axis of the transmission shaft 350 and is perpendicular to it. The movable slide rail 320 meshes with the drive gear 360 on the side wall facing the cooking chamber 100. The following explanation is based on the clockwise rotation of the drive member 310: When the drive member 310 rotates clockwise, it drives the transmission shaft 350 to rotate counterclockwise through the transmission assembly 340. The transmission shaft 350 drives the first bevel gear 371 to rotate counterclockwise. The first bevel gear 371 drives the second bevel gear 372 to rotate clockwise. The second bevel gear 372 drives the drive gear 360 to rotate clockwise. The drive gear 360 then moves the movable slide rail 320 downward.

[0064] The first bevel gear 371 and the second bevel gear 372 cooperate to change the direction of rotation, thereby enabling the movable slide rail 320 to mesh with the drive gear 360 towards the inner wall of the cooking chamber 100, which facilitates the installation of the fixed track 330.

[0065] Furthermore, see Figure 3 As one embodiment of the transmission assembly 340, the transmission assembly 340 includes a first spur gear 341 and a second spur gear 342 that mesh with each other. The first spur gear 341 is connected to the drive member 310, and the second spur gear 342 is mounted on the transmission shaft 350.

[0066] The first spur gear 341 and the second spur gear 342 mesh to achieve the transmission connection between the drive component 310 and the transmission shaft 350.

[0067] As another embodiment of the transmission assembly 340, the transmission assembly 340 includes a driving pulley, a driven pulley and a timing belt. The driving pulley is connected to the driving member 310, the driven pulley is mounted on the transmission shaft 350, and the driving pulley and the driven pulley are connected by the timing belt.

[0068] The driving wheel and the driven wheel are connected by a synchronous belt to realize the transmission connection between the driving component 310 and the transmission shaft 350.

[0069] In an optional embodiment of this utility model, the cooking appliance further includes a rangefinder 400, which is installed on the top wall of the cooking chamber 100 to measure the position of the heat source component 200; the rangefinder 400 is signal-connected to the drive component 300.

[0070] Specifically, the rangefinder 400 is configured as a displacement sensor to detect the position of the heat source assembly 200, and thus detect the vertical distance between the food and the heat source assembly 200. Furthermore, a temperature sensor is also installed inside the cooking chamber 100, and the temperature sensor is signal-connected to the drive unit 310.

[0071] The rangefinder 400 measures the distance between the heat source component 200 and the food, thereby enabling intelligent control of the food's temperature.

[0072] In an optional embodiment of this utility model, the cooking appliance further includes a controller 500, which is installed on the outer wall of the housing 110, and the rangefinder 400, temperature sensor and drive unit 310 are all connected to the controller 500 via signal.

[0073] The controller 500 serves as the main control unit for controlling the heat source component 200, and controls the specific location and temperature of the heat source component 200.

[0074] In an optional embodiment of this utility model, the heat source assembly 200 includes a heat source shelf 210 and a heating tube 220, with the heating tube 220 mounted on the heat source shelf 210 and connected to the drive assembly 300 via transmission.

[0075] Specifically, the heating element 220 is connected to the power supply via a ribbon cable, which can be partially hidden in the sliding rail 320 or partially hidden in the side wall of the housing 110 to realize the heating function of the heating element 220. The heat source shelf 210 is formed by bending a tubular structure, which reduces the weight of the heat source shelf 210 and reduces the power required by the drive component 310.

[0076] The heat source shelf 210 serves to support and fix the heating tube 220.

[0077] The following describes the working process of cooking utensils:

[0078] S1: Set the working mode and corresponding parameters on the controller 500, and start working;

[0079] S2: According to the set parameters, the controller 500 starts different heating elements (multiple heating elements are installed in the cooking appliance, including the heat source component 200 mentioned above) to work alternately or synchronously, so that the temperature of the center of the cooking cavity is heated to the target temperature.

[0080] S3: If the set target temperature is higher than the normal temperature range (35~250℃); at this time, after the controller 500 detects that the temperature at the center of the cavity has risen to 250℃, it starts the drive unit 310 to rotate forward, driving the heat source component 200 to descend and approach the food for heating, so that the temperature rises to exceed the target temperature of 250℃, and at this time the controller 500 sets the timer T0.

[0081] S4: When the temperature reaches the target temperature or the timer ends, the drive unit 310 reverses, causing the heat source component 200 to rise and move away from the food; (Note: S3 and S4 can cycle multiple times, depending on the cooking method and characteristics of the food being cooked).

[0082] S5: The height to which the heat source component 200 descends is determined by measuring the distance between the food and the original position of the heat source using a vertical rangefinder 400, as detailed below:

[0083] a: When it is detected that the drive unit 310 is to be activated to move the heat source component 200 downward, the controller 500 sends a command to the vertical rangefinder 400 to test the distance L1.

[0084] b: Compare the distances L1 and L0 detected in step a (L0: the rated maximum distance between the heat source component 200 and the vertical rangefinder 400); if: L1-L0<0; it means that the distance between the heat source component 200 and the food meets the descent requirement, start the drive component 310, and move the heat source component 200 downward; if: L1-L0=0; it means that the distance between the heat source component 200 and the food is too close and cannot meet the descent requirement; stop the drive component 310 from rotating.

[0085] S6: After the cooking process is completed, the controller 500 shuts off the heating element and stops the load; the operation ends.

[0086] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0087] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
