Description

Technical Field

[0001] The invention relates to the field of kitchen appliances, and in particular to a water tank pushing mechanism of a cooking appliance with a steaming function and a steaming and baking all-in-one machine equipped with the water tank pushing mechanism. Background Art

[0002] Cooking appliances with steaming function can use steam heating technology to lock in the original flavor of food. Such cooking appliances all include a water tank for generating steam, and the water tank is mainly installed in two ways: external and internal.

[0003] Taking the steam oven as an example, the external water tank is mainly installed on the top of the steam oven. A small opening is opened on the control panel a so that the water tank b can be pushed in and out from the glass of the control panel a. Figure 1 As shown. This installation method causes the glass of the control panel to crack, affecting the aesthetics and integrity of the control panel. The built-in water tank structure hides the water tank inside the steam-bake machine, mainly behind the door or behind the control panel; the built-in water tank is mainly hidden behind the door. If the machine alarms for water shortage during cooking, the user needs to pause cooking and open the door to take out the water tank to add water, which will affect the effect and taste of the food being cooked. Placing the water tank behind the control panel and adding water during cooking can avoid the problem of a large amount of steam escaping during cooking and affecting the cooking effect. However, the existing water tank ejection mechanism installed behind the control panel usually adopts a motor-driven gear rack structure. The gear rack structure will produce large jitters during movement, causing the water in the water tank to shake violently. It will also produce large noise, low working stability, and poor user experience.

[0004] In summary, the water tank ejection mechanism installed behind the control panel needs to be further optimized and improved. Summary of the invention

[0005] In view of the problems existing in the prior art, the first purpose of the present invention is to provide a water tank push-out mechanism for a cooking appliance with a steaming function, which ensures the aesthetics and integrity of the control panel while enabling the water tank push-out mechanism to work stably and improve user experience.

[0033] In order to more clearly explain the technical solution in the present invention, the present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Example

[0034] like Figure 2-3 As shown, this embodiment provides a water tank pushing mechanism of a cooking appliance with a steaming function of the present invention, including a crank driving mechanism, which is respectively connected to a control panel and a water tank located at the rear side of the control panel; the crank driving mechanism is used to drive the control panel to flip open and push the water tank out of the cooking appliance at the same time.

[0035] The water tank pushing mechanism of the present embodiment can drive the control panel to open and push the water tank out of the cooking appliance at the same time, so as to add water into the water tank. The water tank pushing mechanism enables the water tank to be installed on the rear side of the entire control panel, thereby ensuring the integrity of the control panel. In addition, the crank drive mechanism is used to execute the pushing out of the water tank and the flipping of the control panel, which can make the water tank pushing out and pushing in process smoother, without generating loud noise, thereby improving the user experience.

[0036] It should be noted that after adding water to the water tank, the control panel and the water tank can be manually reset, and the crank drive mechanism can also drive the water tank into the cooking appliance and reset the electric control panel. The cooking appliance with steaming function in this embodiment can be a steamer, a steam-bake integrated machine, a steam-bake micro integrated machine, etc.

[0037] In this embodiment, the crank drive mechanism includes: a rotating arm 4, a first swing arm 6 having one end rotatably connected to the rotating arm 4, a slide groove structure 7 installed on the cooking appliance, and a slider 10 installed in the slide groove of the slide groove structure 7; the other end of the first swing arm 6 is rotatably connected to the slider 10; and the slider 10 is connected to the water tank.

[0038] The first swing arm 6 is driven by the rotating arm 4 to drive the slider 10 to slide in the slide groove, thereby driving the water tank to be pushed out and into the cooking appliance.

[0039] In this embodiment, the two ends of the first swing arm 6 are respectively connected to the rotating arm 4 and the slider 10 in the form of a rotating pair, and the rotating pair contact middle piece adopts a bearing; the slider 10 is connected to the slide groove structure 7 in the form of a moving pair, and the moving pair contact middle piece adopts a slide groove track. In other embodiments, the two ends of the first swing arm 6 can be respectively hingedly connected to the rotating arm 4 and the slider 10.

[0040] In this embodiment, the crank drive mechanism further includes a second swing arm 11; one end of the second swing arm 11 is rotatably connected to the slider 10, and the other end of the second swing arm 11 is connected to the control panel. When the slider 10 slides to drive the water tank to move, the second swing arm 11 can be driven to drive the control panel to flip.

[0041] Similarly, the second swing arm 11 is connected to the slider 10 in the form of a revolute pair, and the revolute pair contact intermediate piece adopts a bearing. In other embodiments, the second swing arm 11 can be hingedly connected to the slider 10.

[0042] Preferably, the other end of the first swing arm 6 and one end of the second swing arm 11 are coaxially rotatably connected to the slider 10 .

[0043] The first swing arm 6 and the second swing arm 11 are coaxially connected to the slider 10 for rotation. When the slider 10 is driven to move, the second swing arm 11 is synchronously moved to synchronously complete the pushing in or pushing out of the water tank and the flipping open or flipping reset of the control panel, thereby reducing the driving distance of the second swing arm 11 and avoiding driving delay or drive jam of the second swing arm 11.

[0044] See also Figure 2 The slider 10 is an L-shaped structure with a first swing arm 6 and a second swing arm 11 protruding from the side ends.

[0045] The portion of the slide block 10 protruding from the first swing arm 6 and the second swing arm 11 is used for mounting a water tank.

[0046] In this embodiment, the crank drive mechanism also includes: a support shaft 8 installed on the side panel of the cooking appliance, a bearing 12 installed on the support shaft 8, and a guide groove 1101 opened along the side of the second swing arm 11; the guide groove 1101 can be a through groove or a blind groove, and the bearing 12 is installed in the guide groove 1101, and driven by the rotating arm 4 and the first swing arm 6, the guide groove 1101 slides on the bearing 12.

[0047] The guide groove 1101 is disposed near the side panel of the cooking appliance. In the present embodiment, the guide groove 1101 is disposed through the second swing arm 11 . In other embodiments, the guide groove 1101 may also be disposed without penetrating the second swing arm 11 .

[0048] In this embodiment, the guide groove 1101 is opened from the middle of the second swing arm 11 to the end connected to the control panel. Through the cooperation of the guide groove 1101 and the bearing 12, it can guide the swing of the second swing arm 11 and the end connected to the control panel, thereby guiding the flipping of the control panel.

[0049] In this embodiment, the water tank ejection mechanism also includes: a motor drive device, an output rod 9 connected to the motor drive device, a balance rod 3, and a fixed base 5; the fixed base 5 and the crank drive mechanism are both in two groups and are arranged side by side at intervals, and the two ends of the rotating arm 4 are respectively fixedly connected to the output rod 9 and one end of the balance rod 3, and the connecting end of the rotating arm 4 after being fixedly connected to the output rod 9 is rotatably connected to the fixed base 5; of course, one end of the rotating arm 4 can also be connected to the output rod 9 by gear meshing, and any connection method that can achieve power transmission between the output rod 9 and the rotating arm 4 can be adopted; as an optional method, the two ends of the balance rod 3 can also be connected to the first swing arms 6 on both sides; the connection between the balance rod 3 and the rotating arm 4 or the first swing arm 6 can be either a fixed connection, a rolling connection, or a rotational connection, as long as the rotating arms 4 and / or the first swing arms 6 on both sides can be moved synchronously.

[0050] See also Figure 2The lower end of the fixed base 5 is fixed to the cooking appliance, both ends of the output rod 9 and the balance rod 3 are connected to the rotating arm 4, and the two rotating arms 4 are installed close to two opposite side panels of the cooking appliance, and the water tank is installed between the sliders 10 on both sides.

[0051] The electric drive device of the present invention comprises: a drive motor 2, a reducer 1 connected to the drive motor 2, and the reducer 1 is connected to an output rod 9, wherein the reducer 1 of the present embodiment is a gear reducer.

[0052] In this embodiment, the two ends of the rotating arm 4 are provided with polygonal fixing holes such as hexagons, triangles or quadrilaterals, and can also be special-shaped fixing holes such as semicircular holes. The output rod 9 and the balance rod 3 are respectively transitionally matched with the fixing holes; a circular mounting hole is provided on the fixed base 5, and the end of the output rod 9 is matched with the mounting hole and can rotate in the mounting hole. Preferably, the cross section of the output rod of this embodiment is a regular hexagon, so that the output rod 9 can be driven to rotate by the gear reducer. At the same time, regular hexagonal fixing holes are provided at both ends of the rotating arm 4, and regular hexagonal prisms that are transitionally matched with the fixing holes of the rotating arm 4 are provided at both ends of the output rod 9. Similarly, regular hexagonal prisms are also provided at both ends of the balance rod 3, so that the two ends of the balance rod 3 are transitionally matched with the fixing holes of the rotating arm 4. A cylinder is also provided at the end of the regular hexagonal prism of the output rod 9, so that the cylinder is matched with the mounting hole on the fixed base 5, so that the fixed output rod 9, the rotating arm 4 and the balance rod 3 can rotate around the mounting hole under the action of the driving motor 2. In order to enable the end of the output rod 9 to be smoothly inserted into the fixing hole on the rotating arm 4, the outer diameter of the cylindrical cross section is smaller than or equal to the diameter of the inscribed circle of the regular hexagonal prism cross section.

[0053] In other embodiments, a cylinder that cooperates with the fixing hole on the fixed base 5 can also be set on the rotating arm 4, which can also enable the fixed output rod 9, the rotating arm 4 and the balance rod 3 to rotate around the mounting hole under the action of the drive motor 2.

[0054] like Figure 3 As shown, the action process of the water tank pushing mechanism in this embodiment can be:

[0055] 1) The driving motor 2 rotates and then decelerates through the reducer 1 to drive the output rod 9 to drive the rotating arm 4 to rotate;

[0056] 2) The rotating arm 4 drives the first swinging rod 6 to move, and the rotation of the rotating arm 4 is converted into the horizontal movement of the slider 10, thereby driving the water tank to move horizontally;

[0057] 3) The guide groove 1101 of the second swing arm 11 swings along the bearing 12, and the connection end between the second swing arm 11 and the control panel swings, causing the control panel to flip over;

[0058] 4) The schematic diagram of the water tank ejection mechanism before (shown by the solid line) and after (shown by the dotted line) ejection is shown in Figure 3 As shown, when the water tank is pushed out of the cooking appliance, the slider 10 drives the water tank to produce an outward horizontal displacement, and the second swing arm 11 drives the control panel to flip outward and upward, leaving a gap for the water tank to be pulled out so as to add water to the water tank; when the water tank is pushed into the cooking appliance, the water tank returns to the inside of the cooking appliance, the control panel flips back to its original position to cover the internal structure above the cooking appliance, and the water tank is hidden behind the control panel again.
