[0087] The invention provides a household appliance.

[0088] In the embodiment of the present invention, Figure 1 and Figure 2 As shown, the household appliance 10 includes a housing 12 and a sound receiving device 14. The sound receiving device 14 is arranged on the inner side of the housing 12. In this way, when the user knocks on the outer side of the housing 12, the vibration of the housing 12 (solid vibration) can make the air around the sound receiving device 14 vibrate and generate sound waves including the user's knocking information. After the sound receiving device 14 receives the sound wave including the user's knocking information, the customer's knocking information can be obtained. The household appliance 10 can be controlled to perform related operations according to the customer's knocking information. For example, when the household appliance 10 is in the off state, when the user knocks on the outer side of the housing 12 once or twice, the household appliance 10 automatically turns on; and when the household appliance 10 is in the on state, when the user knocks on the outer side of the housing 12 once or twice, the household appliance 10 automatically turns off. Controlling the household appliance 10 to perform related operations according to the customer's knocking information is very convenient and quick to control the household appliance.

[0089] In this embodiment, when the housing 12 is tapped, the portion of the housing 12 corresponding to the sound receiving device 14 is tapped. In this way, it is more conducive to the sound receiving device 14 to receive the sound waves. It is understood that in other embodiments, other portions of the housing 12 may also be tapped, as long as the sound waves including the user's tapping information can be received by the sound receiving device 14.

[0090] In this embodiment, the housing 12 includes a front panel 12 a. The sound receiving device 14 is disposed on the inner side of the front panel 12 a. In this way, it is more convenient for the user to knock on the housing 12 corresponding to the sound receiving device 14.

[0091] In this embodiment, if Figure 3-Figure 6 As shown, the sound receiving device 14 includes a vibration conducting component 14a and a sound wave receiving component 14b. The vibration conducting component 14a is used to conduct the vibration generated by the knocking, and makes the air located on the knocking sound transmission path vibrate to generate sound waves received by the sound wave receiving component 14b. When the part of the shell 12 corresponding to the sound receiving device 14 is knocked, the knocking direction is the same as the knocking sound transmission path, and when the other parts of the shell 12 are knocked, the knocking direction is different from the knocking sound transmission path.

[0092] In actual applications, the abnormal sound of the household appliance 10 itself, the noisy sound of the environment around the household appliance 10, and other sounds other than those generated by knocking on the household appliance may also trigger the household appliance to operate, resulting in the "over-sensitivity" phenomenon in the method of controlling the household appliance by knocking on the household appliance; and in the "non-sensitive" case, knocking on the household appliance may not trigger the household appliance to operate. That is, in actual applications, the method of controlling the household appliance by knocking on the household appliance is prone to "over-sensitivity" or "non-sensitivity", resulting in low accuracy in controlling the household appliance.

[0093] In the present embodiment, a vibration transmission component 14a is provided, and the vibration generated by the knocking is transmitted through the vibration transmission component 14a. The solid conduction mode of "the vibration transmission component 14a transmits the vibration generated by the knocking" makes the acoustic loss coefficient of the sound generated by the knocking household appliance much smaller than the acoustic loss coefficient of the sound generated by the non-knocking household appliance, so that the sound waves generated by the knocking household appliance on the knocking sound transmission path can be effectively transmitted to the sound wave receiving component 14b, while the sound waves of the sound generated by the non-knocking household appliance are difficult to be transmitted to the sound wave receiving component 14b, thereby effectively improving the "over-sensitivity" or "insensitivity" phenomenon, thereby improving the accuracy of household appliance control. That is, in the present embodiment, by planning the transmission path of the sound waves generated by the knocking to the sound wave receiving component 14b, the acoustic loss coefficients of the knocking sound transmission path and the non-knocking sound transmission path are different, thereby effectively improving the "over-sensitivity" and "insensitivity" phenomenon, thereby improving the accuracy of household appliance control.

[0094] In this embodiment, the side of the vibration conducting component 14a away from the sound wave receiving component 14b is used to be in close contact with the struck piece. The vibration conducting component 14a is in close contact with the struck piece, which is very convenient for the vibration conducting component 14a to receive the vibration generated by the striking.

[0095] In this embodiment, if Figure 7-Figure 10 As shown, the vibration conducting component 14a includes a vibration conducting plate 200. The vibration conducting plate 200 is used to conduct the vibration generated by the knocking, and make the air located on the knocking sound transmission path vibrate to generate sound waves for the sound wave receiving component 14b to receive. The side of the vibration conducting plate 200 away from the sound wave receiving component 14b is used to be in close contact with the knocked part.

[0096] In this embodiment, the vibration conducting plate 200 has a receiving side 202 and a conducting side 204 located on the knocking sound transmission path. The receiving side 202 is used to be in close contact with the knocked part. In this embodiment, the knocked part is the housing 12 of the air conditioner indoor unit. It can be understood that in other embodiments, when the above-mentioned vibration conducting component 14a is applied to household appliances 10 such as washing machines and ovens, the knocked part can be the housing of each household appliance 10.

[0097] In this embodiment, the thickness of the vibration conduction plate 200 is 0.5-5.0 mm. If the thickness of the vibration conduction plate 200 is too small, the vibration conduction plate 200 is easy to vibrate, resulting in the "over-sensitivity" phenomenon of the method of controlling the household appliance by knocking the household appliance. If the thickness of the vibration conduction plate 200 is too large, the vibration conduction plate 200 is not easy to vibrate, resulting in the "insensitivity" phenomenon of the method of controlling the household appliance by knocking the household appliance. Taking the above factors into consideration, the thickness of the vibration conduction plate 200 is set to 0.5-5.0 mm.

[0098] In this embodiment, the area of ​​the vibration conducting plate 200 is 5-50 cm 2 If the area of ​​the vibration conduction plate 200 is too large, the vibration conduction component 14a will be too large. If the area of ​​the vibration conduction plate 200 is too small, the vibration conduction effect of the vibration conduction plate 200 will be poor, and it will not be easy to knock the part of the housing 12 corresponding to the vibration conduction plate 200. Taking the above factors into consideration, the area of ​​the vibration conduction plate 200 is set to 5-50cm 2 .

[0099] In this embodiment, the vibration conducting plate 200 is rectangular. Compared with a circular or square shape, a rectangular vibration conducting plate 200 is more conducive to conducting the vibration generated by knocking.

[0100] In this embodiment, the width of the vibration conducting plate 200 is 0.5-0.8 times the length of the vibration conducting plate 200. In this way, it is more conducive for the vibration conducting plate 200 to conduct the vibration generated by the knocking.

[0101] In this embodiment, the material of the vibration conduction plate 200 is plastic or metal, so that the vibration conduction plate 200 is more conducive to conducting the vibration generated by the knocking.

[0102] In this embodiment, the vibration conduction component 14a also includes a sound insulation ring 300. The sound insulation ring 300 is provided on the conduction side 204, and is used to be plugged with the sound wave receiving component 14b on the percussion sound transmission path to isolate the sound waves of the sound wave receiving component 14b in the circumferential direction of the percussion sound transmission path. That is, when the sound wave receiving component 14b is plugged into the sound insulation ring 300, the sound waves on the non-percussion sound transmission path are isolated by the sound insulation ring 300 and cannot be received by the sound wave receiving component 14b. In this way, the phenomenon of "oversensitivity" or "insensitivity" can be further improved, thereby improving the accuracy of household appliance control.

[0103] In this embodiment, the sound insulation ring 300 is made of a plastic damping material or an elastic material (eg, rubber).

[0104] In this embodiment, the sound insulation ring 300 has a receiving cavity 302. The receiving cavity 302 is used to receive the sound wave receiving component 14b plugged into the sound insulation ring 300 on the percussion sound transmission path. The vibration transmission component 14a and the sound wave receiving component 14b close to the end of the vibration transmission plate 200 can cooperate to form an air cavity 304 isolated from the outside world, and the vibration transmission component 14a can make the air in the air cavity 304 vibrate to generate sound waves for the sound wave receiving component 14b to receive.

[0105] In some embodiments, Figure 7-Figure 10 As shown, the vibration conducting component 14a further includes a boss 400, which is disposed on the conducting side 204. The sound insulation ring 300 is disposed on the boss 400. The sound insulation ring 300, the boss 400 and one end of the sound wave receiving component 14b close to the vibration conducting plate 200 can cooperate to form an air cavity 304. By providing the boss 400 to install the sound insulation ring 300, it is more convenient to position and assemble the sound insulation ring 300, and it is convenient to form the air cavity 304. In this way, when the housing 12 is struck, the vibration of the housing 12 is transmitted to the vibration conducting plate 200, and the vibration conducting plate 200 and the boss 400 vibrate accordingly.

[0106] In this embodiment, the boss 400 is integrally formed with the vibration conducting plate 200. This makes it easier to manufacture the vibration conducting component 14a.

[0107] In this embodiment, the height of the boss 400 is less than or equal to 5 cm. In this way, it is possible to avoid the gap between the sound wave receiving component 14 b and the vibration conducting plate 200 being too large, which would lead to excessive sound wave loss.

[0108] In this embodiment, the outer diameter of the boss 400 gradually decreases in the direction from the receiving side 202 to the conducting side 204. This is more conducive to the vibration of the boss 400.

[0109] In this embodiment, the boss 400 includes a plurality of stacked bosses 410, the outer diameter of which gradually decreases from the receiving side 202 to the conducting side 204, and the plurality of bosses 410 are coaxially arranged, so that a step surface is formed between adjacent plurality of bosses 410. In this way, not only the positioning and assembly of the sound insulation ring 300 is facilitated, but also the vibration of the boss 400 is facilitated.

[0110] In some embodiments, Fig.11 As shown, the sound insulation ring 300 is directly arranged on the conduction side 204. In this case, the boss 400 can be omitted. In this embodiment, the sound insulation ring 300 has a receiving cavity 302 and an air cavity 304 that are connected to each other. The receiving cavity 302 is used to receive the sound wave receiving component 14b plugged with the sound insulation ring 300 on the percussion sound transmission path. The air cavity 304 is closer to the vibration conduction plate 200 than the receiving cavity 302. In this way, when the shell 12 is knocked, the vibration of the shell 12 is transmitted to the vibration conduction plate 200, and the vibration conduction plate 200 vibrates accordingly, and the air in the air cavity 304 vibrates to generate sound waves for the sound wave receiving component 14b to receive.

[0111] exist Fig.10 and Figure 12-14 In the illustrated embodiment, the sound insulation ring 300 has a receiving cavity 302. The receiving cavity 302 is used to receive the sound wave receiving component 14b plugged into the sound insulation ring 300 on the percussion sound transmission path. A groove 402 is provided at one end of the boss 400 away from the vibration conduction plate 200, and the groove 402 is connected to the receiving cavity 302. The bottom of the groove 402 can be spaced from the sound wave receiving component 14b to form an air cavity 304. The air cavity 304 is closer to the vibration conduction plate 200 than the receiving cavity 302. In this way, when the housing 12 is struck, the vibration of the housing 12 is transmitted to the vibration conduction plate 200, and the vibration conduction plate 200 and the boss 400 vibrate accordingly, and the air in the air cavity 304 vibrates to generate sound waves received by the sound wave receiving component 14b.

[0112] exist Fig.10 and Figure 12-14 In the illustrated embodiment, the wall thickness of the groove 402 is 0.3-3.0 mm. If the wall thickness of the groove 402 is too small, the boss 400 is easy to vibrate, resulting in the "over-sensitivity" phenomenon of the method of controlling the household appliance by knocking the household appliance. If the wall thickness of the groove 402 is too large, the boss 400 is not easy to vibrate, resulting in the "insensitivity" phenomenon of the method of controlling the household appliance by knocking the household appliance.

[0140] In this embodiment, the distance between the vibration conduction plate 200 and the circuit board 700 is 1-5 cm. In this way, an air resonance cavity can be formed between the vibration conduction plate 200 and the circuit board 700 to amplify the sound transmitted by the vibration conduction plate 200, thereby improving the sensitivity of the sound receiving device 14 to the sound waves generated by the knocking.

[0141] In this embodiment, the sound wave receiving module 600 and the vibration conducting component 14a are both located at one end in the length direction of the circuit board 700.

In this embodiment, when the mounting base 800 is connected with the housing 12, the receiving side 202 of the vibration conducting plate 200 is in close contact with the inner wall of the housing 12.

[0144] It can be understood that when the shape of the receiving side 202 matches the shape of the inner wall of the housing 12, the receiving side 202 can be better fitted to the inner wall of the housing 12. The shape of the receiving side 202 can be designed according to the shape of the inner wall of the housing 12. Figure 2-Figure 6 In the illustrated embodiment, the vibration conducting plate 200 is rectangular and the receiving side 202 is planar.

In this embodiment, the material of the mounting base 800 is a metal material, a damping material or a composite material, wherein the composite material includes at least two of a metal material, a damping material and a plastic.

[0148] In this embodiment, the wall thickness of the mounting base 800 is 1-10 mm. If the wall thickness of the mounting base 800 is too small, the sound insulation effect is limited, and the strength of the mounting base 800 is limited, while if the wall thickness of the mounting base 800 is too large, the volume of the sound receiving device 14 will be too large. Taking the above factors into consideration, the wall thickness of the mounting base 800 is set to 1-10 mm.
