Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliance structures, in particular to a household electrical appliance. Background Art

[0002] Conventional household appliances, such as steam ovens, ovens, dishwashers, etc., are usually equipped with handles on their doors. The operation of opening and closing the door requires the user to hold the handle and push and pull the door. Due to the sealing requirements of the appliance itself during operation, the closing force generated by the hinges installed on the door is relatively large, generally 50 to 100N. Customers need to overcome this closing force to open the door smoothly, and the door opening action is relatively laborious.

[0003] In order to solve the problem of laborious door opening, some existing technologies use electric push door to open the door. In this way, the user needs to give the household appliance a signal to trigger the door opening action, usually by touching the display panel, pressing the door opening button, etc. This door opening method requires the user to accurately touch a specific area, and there is a high probability of false triggering during operation. Utility Model Content

[0004] Based on this, it is necessary to provide a household appliance to address the above problem, which can accurately determine the timing of door opening according to the user's actions and reduce the probability of mistaken door opening.

[0005] A household appliance, comprising:

[0006] A main body part, wherein a cooking cavity is disposed in the main body part, and the cooking cavity is formed with an opening on a side surface of the main body part;

[0007] A door body, which is connected to the main body and is used to open or close the opening;

[0008] A sensing component, the sensing component is installed on the main body or the door body, and includes a knocking sensing element, a vibration detection element and a touch detection element, the vibration detection element and the touch detection element are used to detect the vibration generated by knocking the knocking sensing element and the action of touching the knocking sensing element respectively;

[0009] an actuator, the actuator being used to drive the door body to move relative to the main body portion to open the opening;

[0010] A controller is electrically connected to the vibration detection element, the touch detection element and the actuator, and is used to control the actuator to drive the door to open when the sensing component detects vibration and touch actions at the same time.

[0011] In the above household appliances, when the user wants to open the opening of the cooking cavity, he or she can use the hand, elbow or other position to knock the knocking sensor in the sensing component. The vibration detection element and the touch detection element can detect the knocking signal and the touch signal respectively. When both signals are detected, the controller can control the actuator to open the door. Compared with the touch display panel, button opening and other forms, the condition for the controller to control the actuator is to detect the vibration and touch signals at the same time. The user's accidental touch, pressing and other actions will not cause the knocking sensor to vibrate and will not trigger the door opening action. Therefore, the probability of accidental door opening is greatly reduced.

[0012] In one embodiment, the knocking sensor includes a knocking plate, a vibration transmission member and a sensing plate member, the knocking plate is fixedly installed relative to the main body, the sensing plate member is connected to the knocking plate through the vibration transmission member, so that the vibration generated when the sensing plate member is knocked can be transmitted to the knocking plate through the vibration transmission member, the vibration detection element is installed on the knocking plate, and the touch detection element is arranged on the sensing plate member.

[0013] With such arrangement, the action of tapping acts on the sensing plate, so the touch detection element can detect the touch action. At the same time, the vibration generated by tapping the sensing plate is transmitted to the tapping plate through the vibration transmission element and detected by the vibration detection element.

[0014] In one embodiment, the sensing component further includes a sensing bracket, and the knocking plate is fixed to the main body through the sensing bracket.

[0015] With such arrangement, the sensing bracket can ensure that the striking plate is reliably mounted, so as to facilitate the connection between the sensing component and the main body or the structure mounted thereon.

[0016] In one embodiment, the household appliance further comprises a cover plate attached to the main body, and a side of the sensing plate on which the touch detection element is mounted abuts against the cover plate.

[0017] In one of the embodiments, the household appliance further comprises a control panel mounted on the main body, and the sensing component and the control panel are spaced apart from each other on the main body and are both located within the area covered by the cover.

[0018] In this way, the control panel and the sensor component are both hidden and installed in the area covered by the cover, so that the overall appearance of the household appliance can be more neat, and the cover can also prevent the sensor component, control panel and other structures from contacting with external water vapor. At the same time, the sensor component is independently arranged on one side of the control panel to avoid mutual interference between the two.

[0019] In one embodiment, the controller is used to control the actuator to drive the door to open when the sensing component detects two vibrations and a touch action.

[0020] With this arrangement, using two vibrations as one of the signals for determining the timing of door opening can further reduce the probability of mistaken door opening.

[0021] In one embodiment, the actuator includes a driving source, a transmission assembly and a push rod, wherein: the driving source is used to output rotational motion outward, the transmission assembly is connected between the driving source and the push rod, and is used to convert the rotational motion into a telescopic motion of the push rod, and the push rod can push the door body to open when extended.

[0022] In one embodiment, the transmission assembly includes a worm connected to the motion output end of the driving source, a worm wheel meshing with the worm, and a lead screw coaxially fixed to the worm wheel. One end of the push rod is provided with a transmission part that cooperates with the lead screw.

[0023] With this arrangement, the rotational motion output by the driving source drives the worm to rotate, and the worm and the worm gear cooperate to form a worm gear and worm matching structure, realizing the spatial transmission of motion and facilitating the flexible arrangement of the driving source. At the same time, the rotation of the worm gear can drive the screw to rotate, and the transmission part at one end of the push rod and the screw form a screw nut kinematic pair, so that the push rod can translate and retract with the rotation of the screw, and finally push the door body to flip open through the other end of the screw.

[0024] In one embodiment, the actuator also includes a first sleeve mounted outside the screw rod, and a second sleeve arranged along the telescopic movement direction of the push rod and connected to or integrally formed with the first sleeve. The transmission part cooperates with the screw rod in transmission within the first sleeve, and the other end of the push rod can extend out of the second sleeve to push the door body to flip open.

[0025] With such arrangement, the first sleeve and the second sleeve can conceal and cover at least part of the rod body of the screw rod and the push rod. When the operating temperature of the household appliance is high, the two sleeves can protect some components in the actuator from being affected by temperature and environment.

[0026] In one of the embodiments, the main body portion includes a partition plate, and the partition plate divides the main body portion to form a heat-insulating installation cavity located on the upper side of the cooking cavity, and the driving source is disposed in the heat-insulating installation cavity.

[0027] In this way, the partition separates a heat-insulating installation cavity independent of the cooking cavity in the main body, and the driving source is arranged in the heat-insulating installation cavity, so that when the operating temperature of the household appliance is high, the driving source can be prevented from being affected by the temperature. In addition, some high-temperature sensitive structural parts in the main body, such as PCB boards, can also be arranged in the heat-insulating installation cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] See also Figure 1 and Figure 2 , Figure 1 The structure diagram of the household appliance in one embodiment of the utility model is shown in a closed state. Figure 2 It is shown in Figure 1 The household appliance shown in the figure is in an open door state. The household appliance provided by one embodiment of the utility model mainly includes a main body 100, a door body 200, a sensing component 300, an actuator 400 and a controller (not marked in the figure). Wherein: a cooking cavity 121 is arranged in the main body 100, and the cooking cavity 121 has an opening formed on a side of the main body 100. The door body 200 is connected to the main body 100 and is used to open or close the opening. In the illustrated embodiment, the lower end of the door body 200 is pivotally connected to the main body 100, that is, the door opening action refers to the door body 200 flipping open relative to the main body 100.

[0051] The sensing component 300 is mounted on the main body 100 or the door 200, and includes a knocking sensing element 31, a vibration detection element, and a touch detection element, wherein the vibration detection element and the touch detection element are respectively used to detect the vibration generated by knocking the knocking sensing element 31 and the action of touching the knocking sensing element 31. In the illustrated embodiment, the sensing component 300 is mounted on the main body 100 so as to be mechanically or electrically connected to other structures of the main body 100.

[0052] The actuator 400 is used to drive the door body 200 to move relative to the main body 100 to open the opening and complete the door opening action. It can be understood that when the door body 200 is pivotally connected to the main body 100 as shown in the figure, the actuator 400 is used to push the door body 200 to flip a certain angle. When the door body 200 is slidably connected to the main body 100, the actuator 400 is adapted to push the door body 200 to slide a certain distance. It can be understood that the actuator 400 can only push the door body 200 to move a certain distance to overcome the initial closing force, but does not necessarily push the door body 200 to move to the angle desired by the user. After slightly opening to a certain extent, the user can still further open the door body 200 to the angle he or she desires.

[0053] In addition, the actuator 400 is used to drive the door body 200. It is not necessary to install the actuator 400 on the main body 100 and directly push the door body 200. The actuator 400 can also be installed on the door body 200 and push the door body 200 in the opposite direction through contact with the main body 100 to achieve the door opening action. In addition, the actuator 400 can also be installed on the main body 100 and the door body 200 respectively according to actual needs.

[0054] The vibration detection element, the touch detection element and the actuator 400 in the controller sensing component 300 are all electrically connected, and are used to control the actuator 400 to drive the door body 200 to move when the sensing component 300 detects vibration and touch actions at the same time. The controller mentioned here can be a master controller in a household appliance, or an independent controller equipped for a door opening action alone.

[0055] Compared with detecting vibration signals alone, such as installing the vibration detection device at the door body shaft of the household appliance in some solutions, the sensing component in the utility model also detects the touch action at the same time. Even if the household appliance accidentally vibrates with a large amplitude, such as a large door closing action, the touch detection element cannot detect the touch action, so the controller will not control the actuator 400 to move. In particular, in previous solutions, in order to improve the sensitivity when knocking to open the door, it is often necessary to arrange the vibration detection device at a position where vibration is easily detected, which is why the door body shaft is selected as the installation position. However, although this improves the detection sensitivity to a certain extent, the probability of false triggering of the door opening action is also increased. In the utility model, it is precisely considering the problem of false triggering that a knocking sensor is separately set to receive the user's knocking, and the vibration and touch actions during knocking are used to comprehensively judge the timing of opening the door, which can well avoid the problem of accidental opening of the door when the household appliance itself vibrates or shakes.

[0056] In order to better avoid false triggering, the controller can only control the actuator 400 to act when the vibration detection element detects two consecutive tapping actions and touch actions. In other words, if the user taps twice in a row, the controller will judge it as a tapping action. If the touch detection element detects a touch action at the same time, the controller will control the actuator 400 to perform the door opening action.

[0057] exist Figure 1 and Figure 2 Based on Figure 5 and Figure 6 As shown in the embodiment shown in the figure, the knocking sensing member 31 includes a knocking plate 311, a vibration transmission member 312 and a sensing plate member 313, wherein: the knocking plate 311 is fixedly installed relative to the main body 100, and the sensing plate member 313 is connected to the knocking plate 311 through the vibration transmission member 312. At the same time, the vibration detection element is installed on the knocking plate 311, and the touch detection element is arranged on the sensing plate member 313. In this way, when the user knocks the sensing plate member 313, the touch detection element installed on the sensing plate member 313 can detect the touch action, and at the same time, the vibration generated by the knocking can be transmitted to the knocking plate 311 through the vibration transmission member 312, and detected by the vibration detection element installed on the knocking plate 311.

[0058] In order to facilitate the fixation between the sensing component 300 and the main body 100 , the sensing component 300 may further include a sensing bracket 32 ​​, and the knocking plate 311 is fixedly connected to the main body 100 through the sensing bracket 32 ​​.

[0059] In one embodiment, the sensing plate 313 is configured as a stainless steel spring, and the vibration transmission member 312 is configured as a spring. In this way, the spring gives the stainless steel spring greater flexibility, so that it can sensitively generate vibration when struck, and reliably transmit it to the striking plate 311 through the spring, ultimately ensuring that the vibration detection element can accurately detect the vibration input to the sensing component 300.

[0060] Combination Figure 3 and Figure 5 As shown in the figure, the main body 100 may include an outer box 11, an inner box 12 and a partition 13, wherein the aforementioned cooking cavity 121 is formed in the inner box 12. The partition 13 separates a heat-insulating installation cavity 111 located on the upper side of the cooking cavity 121 between the inner and outer boxes, and the heat-insulating installation cavity 111 may be used to install electrical components in the household appliance, such as the driving source 41 in the actuator 400 mentioned later. In some embodiments, a fan or other structure for heat dissipation may be configured in the heat-insulating installation cavity 111.

[0061] The household appliance may further include a cover plate 600 attached to the main body 100, and a side of the sensing plate 313 equipped with a touch detection element abuts against the cover plate 600. In this way, the touch action generated by the user's tapping can be detected by the touch detection element through the cover plate 600, and when the cover plate 600 is tapped, the cover plate 600 can directly transmit the vibration to the sensing plate 313 abutting against it. In this way, the cover plate 600 can protect the sensing component 300. At the same time, the sensing plate 313 abuts against the cover plate 600, so that the sensing plate 313 remains stable to a certain extent, and will not produce vibration-like actions with the shaking of the main body 100, etc., further reducing the probability of false triggering.

[0062] The household appliance further comprises a control panel 500 mounted on the main body 100. Figure 5 As shown in , the sensing component 300 and the control panel 500 are arranged at intervals on the main body 100, and are both located in the area covered by the cover plate 600. In other words, the cover plate 600 originally used to cover the control panel 500 on the household appliance also serves as a protective structure for the sensing component 300, and the sensing component 300 and the control panel 500 remain relatively independent and do not interfere with each other. In some embodiments, a door opening button for touch can be provided on the control panel 500, and the door opening action can also be realized by touching the door opening button alone.

[0063] In addition, the household appliance in the utility model can be set as an oven, a steam oven, a microwave oven and the like.

[0064] like Figure 4 , Figure 7 , Figure 8 and Fig. 9As shown in the figure, the actuator 400 includes a driving source 41, a transmission component 42 and a push rod 43, wherein: the driving source 41 is used to output rotational motion outward, and it can be selected from a servo motor or a stepper motor, etc. The transmission component 42 is connected between the driving source 41 and the push rod 43, and is used to convert the rotational motion into the telescopic motion of the push rod 43. When the push rod 43 is extended, it can push the door body 200 to move.

[0065] In the illustrated embodiment, the transmission assembly 42 includes a worm 421 connected to the motion output end of the driving source 41, a worm wheel 422 meshing with the worm 421, a screw 423 coaxially fixed with the worm wheel 422, and a transmission part 431 that cooperates with the screw 423 is provided at one end of the push rod 43. The worm 421 and the worm wheel 422 form a spatial gear transmission structure, so that the driving source 41 can be perpendicular to the arrangement direction of the screw 423, which is convenient for the installation and arrangement of the driving source 41. In some embodiments, a reduction motor can be directly selected as the driving source 41. Since the reduction motor has a reduction gear box structure, the worm gear transmission structure can be eliminated, or it is only used to change the direction of motion transmission.

[0066] Further integration Fig.10 As shown in the figure, in order to realize the circumferential linkage between the screw rod 423 and the worm wheel 422, a circumferential connecting member 4231 is provided at one end of the screw rod 423, and correspondingly, a circumferential connecting hole 4221 is provided at the rotation center of the worm wheel 422. The circumferential connecting member 4231 and the circumferential connecting hole 4221 are non-rotating structures with matching shapes, so that the screw rod 423 can be driven to rotate synchronously when the worm wheel 422 rotates.

[0067] Return to reference Figure 7 , Figure 8 and Fig. 9 As shown in the embodiment shown in the figure, the transmission part 431 at one end of the push rod 43 cooperates with the screw rod 423 to form the screw nut pair. The transmission part 431 is equivalent to the screw nut in the screw nut pair, and is used to convert the rotation of the screw rod 423 into translational motion, so that the push rod 43 can reciprocate and telescopic motion. In other embodiments, the transmission part 431 can also be a structure independent of the screw rod 423, and is fixedly connected to one end of the screw rod 423 in the assembled state.

[0068] In addition, the actuator 400 may also include a first sleeve 44 sleeved outside the screw rod 423, and a second sleeve 45 arranged along the telescopic movement direction of the push rod 43 and connected to or integrally arranged with the first sleeve 44. The transmission part 431 and the screw rod 423 are transmission-coordinated in the first sleeve 44, and the other end of the push rod 43 can extend out of the second sleeve 45 to push the door body 200. As mentioned above, the driving source 41 in the actuator 400 is installed in the heat-insulating installation cavity 111. In order to ensure that the door body 200 can be pushed by the push rod 43, other structures in the actuator 400 need to be arranged in the space between the inner and outer boxes. The arrangement of the first sleeve 44 and the second sleeve 45 can protect the internal structure from being affected by the space temperature.

[0069] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
