Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to an integrated stove and a control method for the integrated stove. Background Art

[0002] An integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the advantages of saving space, good fume extraction effect, energy saving, low consumption and environmental protection.

[0003] When designing existing integrated stoves, in order to save space and ensure that the user's view is not blocked by the pot during use, the size of the top baffle of the stove is shortened as much as possible. In order to prevent the integrated stove from blocking the view and affecting the user experience, some manufacturers have an arc-shaped structure for their products without a top smoke baffle structure. For example, the Chinese utility model "An Integrated Stove" with patent number CN201420241681.6 (application publication number CN203837065U) discloses an integrated stove without a top smoke baffle structure.

[0004] However, if the integrated stove has no smoke shield or the shield is too small, some of the smoke will always escape when the oil smoke rises and spreads, and the oil smoke cannot be completely extracted. If the shield is too small, the negative pressure area is small, and the extraction effect is not particularly ideal, which affects the user experience. In addition, if the shield is too large, it may hit the pot and block the view, which also affects the user experience. Therefore, further improvements are needed to the existing integrated stove. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide an integrated stove that can provide an enhanced smoke collection effect function or a function to avoid pot collision and vision obstruction according to different cooking scenes, in response to the above-mentioned existing technology.

[0006] The second technical problem to be solved by the present invention is to provide an integrated stove that further expands the negative pressure area to improve the smoking effect while enhancing the smoke-collecting effect.

[0007] The third technical problem to be solved by the present invention is to provide a control method for the above-mentioned integrated stove.

[0008] The technical solution adopted by the present invention to solve the first technical problem is: an integrated stove, comprising:

[0009] a cabinet body having a cavity therein;

[0010] The stove is installed on the countertop of the cabinet;

[0011] A smoke collection chamber is provided behind the stove, the interior of which is hollow and has a smoke collection cavity and is connected to the cavity of the cabinet. The front side wall of the smoke collection chamber has an air inlet connected to the smoke collection cavity at a position above the table;

[0012] a smoke shield assembly, located above the air inlet and extending forward;

[0013] It is characterized by: further comprising:

[0014] The first smoke shield is constrained on the smoke shield assembly in a manner capable of forward and backward translation, and at least partially has a first state in which it can be retracted relative to the smoke shield assembly and a second state in which it is exposed relative to the smoke shield assembly;

[0015] The first driving mechanism is used to drive the first smoke shield to move forward and backward.

[0016] In order to achieve smooth movement of the first smoke shield, it also includes a guide rail extending along the front-rear direction of the first smoke shield and a slider slidably arranged in the guide rail, and the first driving mechanism is drivingly connected to the slider.

[0017] To achieve forward and backward translation of the first smoke shield, the first driving mechanism includes a first motor and a screw rod, the screw rod extends along the length direction of the guide rail, the first motor is transmission-connected to the screw rod, and the slider is slidably constrained on the screw rod.

[0018] To solve the second technical problem mentioned above, the system further includes a second smoke deflector and a second driving mechanism. The second smoke deflector is constrained on the second smoke deflector in a manner that allows it to rotate relative to the front end of the first smoke deflector. The second driving mechanism is used to drive the second smoke deflector to rotate.

[0019] In order to simplify the structure of the second driving mechanism and save costs, preferably, the second driving mechanism includes a second motor, a first swing arm and a second swing arm, one end of the first swing arm is connected to the second motor drive, the other end of the first swing arm is hinged to one end of the second swing arm, and the other end of the second swing arm is connected to the wall surface of the second smoke shield.

[0020] In order to achieve the smoke guiding and diversion function according to the actual usage scenario or extend the horizontal distance of the smoke shield to improve the smoke gathering effect, the angle formed between the second smoke shield and the first smoke shield is α, and the value range of α is 20°≤α≤180°.

[0021] In order to make the integrated stove more beautiful as a whole, the smoke shield component is hollow inside and open at the front, and the first smoke shield plate is constrained in the smoke shield component.

[0022] Furthermore, the second smoke shield has at least a third state in which the opening of the smoke shield assembly is closed when the first smoke shield is in the first state, and a fourth state in which the opening of the smoke shield assembly is opened and can be deflected relative to the first smoke shield when the first smoke shield is in the second state.

[0023] In order to expand the negative pressure area, the smoke blocking component is communicated with the smoke collecting chamber.

[0024] In order to realize automatic control of the above-mentioned first smoke shield and the second smoke shield, it also includes a detection element for detecting wind direction information arranged adjacent to the smoke shield component and a controller connected to the detection element. The controller is also connected to the first drive mechanism and the second drive mechanism, and is configured to control the first drive mechanism and the second drive mechanism to perform corresponding actions according to the detection results of the detection element.

[0025] The technical solution adopted by the present invention to solve the third technical problem is: a control method using the above integrated stove, characterized by comprising the following steps:

[0026] Step 1: Collect wind direction information T1 near the front side of the smoke shield assembly;

[0027] Step 2: Determine whether the wind direction information T1 is less than a preset threshold value Tk. If so, maintain the current positions of the first and second smoke shields and proceed to step 1; if not, proceed to step 3.

[0028] Step 3: Adjust the second smoke deflector plate to a maximum initial angle αm with the first smoke deflector plate;

[0029] Step 4: Collect the wind direction information T1 near the front of the smoke barrier component and determine whether the wind direction information T1 has changed significantly. If so, proceed to step 2; if not, proceed to step 5.

[0030] Step 5: Determine whether the angle α at this time is greater than or equal to the minimum threshold α0. If so, reduce the angle α between the second smoke shield and the first smoke shield, and proceed to step 4; if not, proceed to step 2.

[0031] In order to determine the included angle between the second smoke deflector and the first smoke deflector more accurately, the included angle α between the second smoke deflector and the first smoke deflector is reduced by the same fixed preset value α3 each time in step 5.

[0032] Compared with existing technologies, the present invention offers the following advantages: by constraining the first smoke deflector to the smoke deflector assembly so that it can translate forward and backward, the amount of translation of the first smoke deflector can be adjusted to suit different cooking scenarios. This enhances smoke containment when using larger cookware, while preventing it from colliding with the pot or obstructing vision when using smaller cookware. Consequently, the integrated stove is highly versatile, has a wide range of applications, and offers a high smoke extraction efficiency, providing a superior user experience.

[0039] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0040] like Figures 1 to 6 As shown, the integrated stove in this embodiment includes a cabinet 1, a cooker 2, a smoke collection chamber 3, and a smoke barrier assembly 4. The cabinet 1 has a cavity within it, which houses other cooking equipment, such as a fan system. For details, please refer to the structure of existing integrated stoves and will not be described in detail here. The cooker 2 is mounted on the countertop 11 of the cabinet 1. The smoke collection chamber 3 is located behind the cooker 2 and has a hollow interior with a smoke collection cavity 31 that communicates with the cavity of the cabinet 1. The front side wall of the smoke collection chamber 3 has an air inlet 32 located above the countertop 11, which communicates with the smoke collection cavity 31. The smoke barrier assembly 4 is located above the air inlet 32 and extends forward.

[0041] The integrated stove in this embodiment further includes a first smoke shield 5 constrained on the smoke shield assembly 4 in a manner capable of translationally moving forward and backward, and a first driving mechanism 6 for driving the first smoke shield 5 to translate forward and backward. The first smoke shield 5 has at least a portion thereof in a first state capable of retracting relative to the smoke shield assembly 4 (e.g., Figure 2 As shown) and the second state relative to the smoke shield assembly 4 exposed (as shown Figure 1 shown).

[0042] like Figure 3 and Figure 5 As shown, to achieve forward and backward translation of the first smoke deflector 5, this embodiment further includes a guide rail 51 extending along the forward and backward direction of the first smoke deflector 5 and a slider 52 slidably disposed within the guide rail 51. A first drive mechanism 6 is drivingly connected to the slider 52. Specifically, the first drive mechanism 6 includes a first motor 61 and a screw rod 62. The screw rod 62 extends along the length of the guide rail 51. The first motor 61 is drivingly connected to the screw rod 62, and the slider 52 is slidably constrained on the screw rod 62. The structure and specific operating principle of the screw rod 62 and the first motor 61 can be referenced in the prior art and will not be elaborated here. Of course, the first drive mechanism 6 described above can also adopt other drive mechanisms in the prior art that can achieve forward and backward translation.

[0043] like Figures 3-5 As shown, the integrated stove also includes a second smoke deflector 7 and a second drive mechanism 8. The second smoke deflector 7 is constrained to the second smoke deflector 7 so that it can rotate relative to the front end of the first smoke deflector 5. The second drive mechanism 8 is used to drive the second smoke deflector 7 to rotate. In this embodiment, the second drive mechanism 8 includes a second motor 81, a first swing arm 82, and a second swing arm 83. One end of the first swing arm 82 is drivingly connected to the second motor 81, and the other end of the first swing arm 82 is hinged to one end of the second swing arm 83. The other end of the second swing arm 83 is connected to the wall surface of the second smoke deflector 7. Of course, the second drive mechanism 8 described above can also adopt other drive mechanisms known in the art.

[0044] The angle formed between the second smoke deflector 7 and the first smoke deflector 5 is α. In this embodiment, the value range of α is preferably 20°≤α≤180°. The specific angle needs to be set according to the actual usage scenario.

[0045] like Figure 6 As shown, in this embodiment, the smoke shield assembly 4 is hollow inside and open at the front, and the first smoke shield plate 5 is constrained in the smoke shield assembly 4; the second smoke shield plate 7 has at least a third state (such as Figure 2 ) and a fourth state (as shown) in which the smoke shield assembly 4 is opened and can be deflected relative to the first smoke shield 5 in the second state. Figure 1 The smoke shield assembly 4 is connected to the smoke collecting chamber 31, so that the negative pressure area can be expanded.

[0046] In addition, the integrated stove further includes a detection element (not shown in the figure) disposed adjacent to the smoke shield assembly 4 for detecting wind direction information, and a controller (not shown in the figure) connected to the detection element. The controller is further connected to the first drive mechanism 6 and the second drive mechanism 8, and is configured to control the first drive mechanism 6 and the second drive mechanism 8 to perform corresponding operations based on the detection results of the detection element. The detection element is a wind sensor for detecting wind direction information, such as an electromagnetic wind direction sensor or a photoelectric wind direction sensor, which obtains the angle of the wind direction. Preferably, it is an ultrasonic wind speed sensor that can simultaneously obtain wind speed and wind direction.

[0047] The control method of the integrated stove comprises the following steps:

[0048] Step 1: Collect wind direction information T1 near the front side of the smoke shield assembly;

[0049] Step 2: Determine whether the wind direction information T1 is less than a preset threshold value Tk. If so, maintain the current positions of the first and second smoke shields and proceed to step 1; if not, proceed to step 3.

[0050] The above-mentioned preset threshold value Tk is the critical value for the occurrence of airflow turbulence, which corresponds to the value used to determine whether turbulence will be generated in the oil smoke airflow in front of the smoke shield component, thereby affecting the oil smoke airflow entering the smoke collecting chamber, causing the integrated stove to affect the exhaust effect; when the airflow turbulence occurs, it means that the integrated stove is leaking smoke; when the airflow does not turbulent (i.e., the airflow is stable), it means that the integrated stove is not leaking smoke;

[0051] Step 3: Adjust the second smoke deflector plate to a maximum initial angle αm with the first smoke deflector plate;

[0052] In this embodiment, αm=180°;

[0053] Step 4: Collect the wind direction information T1 near the front of the smoke barrier component and determine whether the wind direction information T1 has changed significantly. If so, proceed to step 2; if not, proceed to step 5.

[0054] In this embodiment, the significant change may be: if the change value of the wind direction information T1 is greater than a certain preset value, it is determined that there is a significant change; otherwise, it is determined that there is no significant change;

[0055] Step 5: Determine whether the angle α at this time is greater than or equal to the minimum threshold α0. If so, reduce the angle α between the second smoke deflector and the first smoke deflector, and proceed to step 4; if not, proceed to step 2;

[0056] In this embodiment, α0=20°; in step 5, the included angle α between the second smoke deflector and the first smoke deflector is reduced by the same fixed preset value α3 each time, for example: α3=5°.

[0057] The working process of the integrated stove in this embodiment is as follows: when the integrated stove is in a non-working state, the second smoke baffle 7 is in a third state (such as Figure 2 As shown), the second smoke baffle 7 plays a sealing and beautifying role, ensuring the consistency of the smoke barrier component 4. When the integrated stove is in working condition, the first smoke baffle 5 can move back and forth, while meeting the function of placing objects on the surface of the smoke barrier component 4, ensuring the smoke-collecting effect of the smoke barrier component 4. After the first smoke baffle 5 is opened, the negative pressure area is increased to solve the problem that the oil smoke cannot be completely absorbed when the front and rear depths of the smoke barrier component 4 are small; of course, the front and rear movement of the first smoke baffle 5 can avoid the situation that the smoke barrier component is too large and touches the pot and blocks the line of sight; at the same time, the second smoke baffle 7 is in the fourth state (as shown). Figure 1 When the angle α formed between the second smoke baffle 7 and the first smoke baffle 5 is 180°, the horizontal distance of the smoke baffle 4 is extended to the maximum extent, which has a good smoke collection effect for super-large cookers.
