For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise specified, "a plurality of" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] To solve the above problems, please refer to Figures 1 to 3 , this application proposes a kitchen appliance 1, which can be a dishwasher or a disinfection cabinet. The dishwasher can automatically clean tableware such as bowls, chopsticks, knives, and forks placed therein, reducing the labor intensity of users and improving the work efficiency of cleaning tableware; the disinfection cabinet refers to a tool that dries, sterilizes, and disinfects, and keeps warm and dehumidifies the tableware placed therein through ultraviolet rays, far-infrared rays, high temperature, ozone, etc., and can improve the cleaning and sanitation effect.

[0031] In the embodiment of this application, the kitchen appliance 1 includes a cabinet body 10, a cabinet door 20, an image acquisition component 30, and a transmission device 40 (see Figure 3)。The cabinet body 10 is for carrying tableware and other functional structures placed therein and needs to have strong structural strength. Therefore, the cabinet body 10 can be made of materials such as stainless steel and aluminum alloy. The cabinet body 10 has a receiving cavity 11 for placing tableware, and the receiving cavity 11 has an access opening 12 for taking in and out tableware; the cabinet door 20 is rotatably connected to the cabinet body 10 to open or close the access opening 12; the image acquisition member 30 is arranged in the receiving cavity 11; the transmission device 40 connects the image acquisition member 30 and the cabinet door 20.

[0032] In the process of the cabinet door 20 of the kitchen appliance 1 according to the technical solution of the present application opening or closing the access opening 12, the cabinet door 20 drives the image acquisition member 30 to move in the receiving cavity 11 through the transmission device 40, so that the image acquisition member 30 can acquire multiple images of the tableware in the receiving cavity 11 from multiple positions. In this way, three-dimensional image reconstruction and other operations can be performed on the tableware placed in the receiving cavity 11 based on the obtained multiple images, so as to more comprehensively and clearly judge the specific placement situation or cleaning status of the tableware, facilitating the kitchen appliance 1 to perform automated work more accurately and efficiently. For example, when the kitchen appliance 1 is a dishwasher, through three-dimensional image reconstruction, the dishwasher can obtain information such as the cleanliness status and position of the tableware, and then adjust the water spraying amount, water spraying intensity, and detergent dosage for spraying.

[0033] When the kitchen appliance 1 in the embodiment of the present application is a dishwasher, the rotation connection direction between the cabinet door 20 and the cabinet body 10 is usually that the cabinet door 20 is rotationally connected in the up-and-down direction of the cabinet body 10, that is, the cabinet door 20 flips up and down relative to the cabinet body 10 (as Figure 4 shown, the rotation axis of the cabinet door 20 is a horizontal axis), so that the cabinet door 20 can open or close the access opening 12; when the kitchen appliance 1 in the embodiment of the present application is a disinfection cabinet, the rotation connection direction between the cabinet door 20 and the cabinet body 10 is usually that the cabinet door 20 is rotationally connected in the side direction of the cabinet body 10, that is, the cabinet door 20 flips left and right relative to the cabinet body 10 (as Figure 1 and Figure 2 shown, the rotation axis of the cabinet door 20 is a vertical axis), so that the cabinet door 20 can open or close the access opening 12.

[0034] Please refer to Figure 3 , a slide rail 13 is arranged on the inner wall of the cabinet body 10, and the transmission device 40 includes a sliding member 41 and a transmission member 42. The sliding member 41 is slidably connected to the slide rail 13, the image acquisition member 30 is arranged on the sliding member 41, and the transmission member 42 connects the sliding member 41 and the cabinet door 20. Among them, in the process of the cabinet door 20 opening or closing the access opening 12, the transmission member 42 drives the sliding member 41 to slide relative to the slide rail 13, so that the image acquisition member 30 arranged on the sliding member 41 can move inside the cabinet body 10 and acquire multiple images of the tableware placed in the cabinet body 10.

[0035] Please refer to Figure 1 In a specific embodiment, the transmission member 42 includes a transmission rod 421. One end of the transmission rod 421 is rotatably connected to the cabinet door 20, and the other end is rotatably connected to the sliding member 41. The rotational connection method can be, for example: both ends of the transmission rod 421 are hinged to the cabinet door 20 and the sliding member 41 respectively. The transmission rod 421 can be connected to the edge of the cabinet door 20, such as near the upper edge or the lower edge of the cabinet door 20, and extend from the edge of the cabinet door 20 towards the access opening 12 and extend into the interior of the cabinet body 10 to be connected to the sliding member 41, so as to avoid the transmission rod 421 causing obstruction at the access opening 12, facilitating the user to place or take tableware at the access opening 12. During the process of the user opening or closing the cabinet door 20, the transmission rod 421 can pull or push the sliding member 41 to slide inside the cabinet body 10.

[0036] Please refer to Figure 2 In another specific embodiment, the transmission member 42 includes a transmission rope 422. The transmission rope 422 has a certain extensibility, which can be an elastic rope or a steel cable structure. One end of the transmission rope 422 is connected to the cabinet door 20, and the other end is connected to the sliding member 41. The transmission rope 422 can be connected to the edge of the cabinet door 20 and arranged along the periphery of the access opening 12. For example, the transmission rope 422 can be arranged along the upper edge or the lower edge of the access opening 12 and extend into the interior of the cabinet body 10 to be connected to the sliding member 41. Similarly, it can avoid the transmission rope 422 causing obstruction at the access opening 12, facilitating the user to place or take tableware at the access opening 12. When the user opens the cabinet door 20, the transmission rope 422 can drive the sliding member 41 to slide inside the cabinet body 10, so that the image acquisition member 30 provided on the sliding member 41 can move inside the cabinet body 10 and acquire the image information inside the cabinet body 10.

[0037] Please refer to Figure 3 In addition, the transmission device 40 further includes a reset member 43. The reset member 43 can be a compression spring, a spring and other structures. One end of the reset member 43 is connected to the cabinet body 10, and the other end is connected to the sliding member 41. The user opens the cabinet door 20, so that the transmission rope 422 drives the sliding member 41 to slide inside the cabinet body 10 and stretches the reset member 43. However, the sliding member 41 is always located on the slide rail 13. During the process of the user closing the cabinet door 20, through the elastic force of the reset member 43 itself, the position of the sliding member 41 is reset, so that the image acquisition member 30 is reset, and the above process can be repeated multiple times to achieve sustainable operation.

[0038] In some embodiments, the image acquisition member 30 may be a device such as a camera, a radar, etc. When the image acquisition member 30 is a camera, it may be a wide-angle camera (e.g., a 180° wide-angle lens), so that the internal situation of the accommodation cavity 11 can be photographed more comprehensively and clearly, and the cost is relatively low. A radar is an electronic device that uses electromagnetic waves to detect targets. The radar emits electromagnetic waves to irradiate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, altitude, etc. Its accuracy is relatively high, the response speed is relatively fast, and it can obtain more comprehensive specific images of the tableware placed inside the accommodation cavity 11.

[0039] In some embodiments, the sliding direction of the image acquisition member 30 may be along the horizontal direction of the cabinet body 10. At this time, the image acquisition member 30 can slide in the horizontal direction of the cabinet body 10, for example, in the depth direction of the cabinet body 10, so that specific images of the part of the cabinet body 10 away from the access opening 12 can be obtained, making the image acquisition more comprehensive.

[0040] Of course, the sliding direction of the image acquisition member 30 may also have an angle with the horizontal direction of the cabinet body 10. This angle can be 0 to 90°, that is, the angle between the sliding direction of the image acquisition member 30 and the horizontal direction of the cabinet body 10 can be 30°, 45°, 60° or 80°. At this time, the sliding direction of the image acquisition member 30 is an oblique line movement. When the angle between the sliding direction of the image acquisition member 30 and the horizontal direction of the cabinet body 10 is 90°, the image acquisition member 30 slides in the up and down direction of the cabinet body 10.

[0041] Alternatively, the sliding path of the image acquisition member 30 is an arc. At this time, by setting the track of the slide rail 13 as an arc, the transmission device 40 drives the image acquisition member 30 to slide on the slide rail 13, and the sliding path of the image acquisition member 30 can be an arc. The sliding direction of the image acquisition member 30 can be adaptively adjusted according to the specific structure inside the cabinet body 10 and the placement position of the tableware in the accommodation cavity 11. This application does not limit this.

[0042] In some embodiments, the image acquisition member 30 is movably arranged between the cavity side wall and the cavity top wall of the accommodation cavity 11. Being relatively high with respect to the placement position of the tableware, it can effectively prevent liquid from splashing onto the image acquisition member 30 during the process of washing the tableware, which affects the clarity of the image acquired by the image acquisition member 30. While improving the waterproof effect, it can also extend the service life of the image acquisition member 30, reduce losses, and save costs. Of course, the image acquisition member 30 can also be arranged on the cavity top wall, which can also achieve the above waterproof effect, and can effectively avoid the tableware placed in the accommodation cavity 11, preventing the image acquisition member 30 from bumping into the tableware during the sliding process and damaging the tableware or the image acquisition member 30. Moreover, this can also enable the image acquisition member 30 to have a larger movement range, so as to be able to acquire multiple images of the tableware placed in the accommodation cavity 11 more comprehensively.

[0043] Furthermore, the image acquisition member 30 takes pictures at least at three different positions, and inputs the multiple pictures obtained from different angles into the three-dimensional reconstruction model, so as to obtain the three-dimensional reconstruction image inside the cabinet body 10 to support subsequent development work. For example, it can present the internal scene to the user more vividly, giving the user a strong intuitive impression. It can also better locate the placement positions of various tableware according to the three-dimensional reconstructed scene, bringing greater convenience to the automatic dishwashing process.

[0044] Please refer to Figures 3 to 5 , in some embodiments, the kitchen appliance 1 further includes a trigger device 50 and a control device 60. The trigger device 50 is arranged on the movement path of the image acquisition member 30, and the control device 60 is electrically connected to the trigger device 50. When the image acquisition member 30 passes by the trigger device 50, the trigger device 50 sends a detection signal to the control device 60, so that the control device 60 controls the image acquisition member 30 to take pictures. In this way, automatic shooting can be realized, and the shooting position is relatively fixed, and the obtained image information is more accurate, improving the use convenience.

[0045] Please refer to Figures 3 to 4 , the trigger device 50 includes multiple groups of electrical contact groups 51. Each group of electrical contact groups 51 includes two electrical contacts 511 arranged at intervals. A conductive member 31 is arranged at the bottom of the image acquisition member 30. During the movement of the image acquisition member 30, the conductive member 31 sequentially conducts the two electrical contacts 511 in multiple groups of electrical contact groups 51 to send out a detection signal, so that the control device 60 controls the image acquisition member 30 to take pictures and obtain multiple images. Since the image acquisition member 30 needs to take pictures at least at three different positions, the number of electrical contact groups 51 is at least three groups, that is, the number of electrical contact groups 51 can be three groups, five groups, six groups, etc. The present application does not limit the number of electrical contact groups 51.

[0046] Furthermore, multiple groups of electrical contact groups 51 are arranged at equal intervals. As a result, the position intervals for obtaining images are equal, enabling more comprehensive acquisition of images at multiple positions and angles, reducing the omission of image information, and thus ensuring the accuracy of subsequent three-dimensional image reconstruction work. It should be noted that the intervals between multiple groups of electrical contact groups 51 can be, for example, 3 cm, 5 cm, 8 cm, etc. The specific values of the intervals between multiple groups of electrical contact groups 51 can be adaptively adjusted according to the volume of the accommodation cavity 11 of the kitchen appliance 1, and this application does not limit it.

[0047] It can be understood that the triggering device 50 can also be at least one of a pressure sensor, a photoelectric sensor, and a magnetic sensor, that is, multiple sensors mentioned above can be set together, or only one of the sensors can be set.

[0048] The pressure sensor mainly measures the pressure generated by an object under force and converts it into a corresponding electrical signal. Generally speaking, a pressure sensor usually includes two parts: a sensing element and a signal processing circuit. The sensing element can sense the pressure change in the surrounding environment and convert it into an electrical signal. The signal processing circuit then amplifies, filters, and converts the electrical signal, and finally outputs the value of the measured pressure.

[0049] The photoelectric sensor realizes control by converting the change in light intensity into a change in electrical signal. Generally, a photoelectric sensor consists of three parts: a transmitter, a receiver, and a detection circuit. The transmitter aims the light beam at the target, and the emitted light beam generally comes from semiconductor light sources, such as light-emitting diodes (LEDs), laser diodes, and infrared emitting diodes. The light beam is emitted continuously or the pulse width is changed. The receiver is composed of a photodiode, a phototransistor, and a photovoltaic cell. In front of the receiver, optical elements such as lenses and apertures are set, and behind it is the detection circuit, which can filter out the effective signal and apply the signal.

[0050] The magnetic sensor converts the change in the magnetic properties of a sensitive element caused by external factors such as magnetic fields, currents, stress and strain, temperature, and light into an electrical signal, and detects the corresponding physical quantity in this way. Magnetic sensors are divided into three categories: compasses, magnetic field sensors, and position sensors. Among them, the working principle of the position sensor is as follows: if there is a position change between a magnet and a magnetic sensor, and this position change is linear, it is a linear sensor; if it rotates, it is a rotational sensor. In addition, current sensors also belong to magnetic field sensors, and they can be used in household appliances, smart grids, electric vehicles, wind power generation, etc.

This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the accompanying drawings are only for illustrative purposes and should not be construed as a limitation of the present application. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.
