[0012] In some embodiments, one side of the first door body towards the second door body is provided with a first groove, and part of the microphone module is arranged in the first groove, and the sound receiving opening is arranged towards the outside of the first groove.

[0013] By adopting the technical scheme of the embodiment, part of the microphone module is arranged in the first groove, the first groove can accommodate part of the microphone module, the size of the microphone module protruding from the side of the first door body is reduced, so that the distance between the microphone module and the second door body is reduced, the probability of collision between the microphone module and the second door body is reduced, and the influence of the microphone module on the opening and closing of the first door body and the second door body is reduced; in addition, the distance between the first door body and the second door body can also be appropriately reduced, which is helpful to improve the overall appearance effect of the refrigerator; the sound receiving opening is arranged outside the first groove, the sound receiving opening is less blocked by the side wall of the first groove, so that the sound can enter the inside of the microphone module through the sound receiving opening, so that the microphone module can accurately receive the voice instruction of the user.

[0014] In some embodiments, the first groove has a first side wall away from the main body, and the microphone module is in abutment with the first side wall.

[0015] By adopting the technical scheme of the embodiment, in the use process of the refrigerator, the user is usually located on the side of the first door body away from the main body, the microphone module is in abutment with the first side wall, the distance between the microphone module and the user is reduced, so that the microphone module can be closer to the user, and the microphone module can more accurately collect the voice instruction of the user.

[0016] In some embodiments, the microphone module comprises a microphone substrate and a microphone body mounted on the microphone substrate, the microphone substrate has a first side edge and a second side edge arranged along a width direction of the microphone substrate, wherein the first side edge is located between the first door body and the second side edge, and the microphone substrate is arranged obliquely relative to the first door body so that a distance between the second side edge and the first door body is less than a width of the microphone substrate.

[0017] By adopting the technical scheme of the present embodiment, generally, a user usually stands in front of the refrigerator, and the microphone substrate needs to be arranged towards the front of the refrigerator so that the microphone body can receive voice instructions from the front of the refrigerator. Arranging the microphone substrate obliquely relative to the first door body can reduce the relative distance between the side of the microphone substrate away from the first door body and the first door body, thereby helping to reduce the size of the microphone module in the direction in which the first door body points to the second door body, thereby reducing the occupied space of the microphone module in this direction, increasing the relative distance between the microphone module and the second door body, and reducing the probability of collision between the microphone module and the second door body.

[0018] In some embodiments, a first included angle θ is formed between the microphone substrate and the side of the first door body facing the second door body, and 40°≤θ≤50°.

[0019] By adopting the technical scheme of the present embodiment, the greater the value of θ, the greater the relative distance between the side of the microphone substrate away from the first door body and the first door body. By arranging the first included angle between the microphone substrate and the side of the first door body facing the second door body to be not greater than 50°, the relative distance between the side of the microphone substrate away from the first door body and the first door body can be controlled within a suitable range, thereby reducing the size of the microphone module in the direction in which the first door body points to the second door body. It can be understood that the smaller the value of θ, the more the microphone substrate deviates from the front of the refrigerator. Arranging the first included angle between the microphone substrate and the side of the first door body facing the second door body to be not less than 40° can limit the amplitude of the microphone substrate deviating from the front of the refrigerator, thereby helping to improve the sound receiving effect of the microphone module.

[0020] In some embodiments, the microphone module comprises a shell connected with the first door body, and the microphone substrate and the microphone body are arranged in the shell, and the shell is provided with the sound receiving port in communication with the microphone body.

[0022] In some embodiments, the shell has a first plate portion, the first plate portion is arranged obliquely, and a side surface of the microphone substrate is attached to a side surface of the first plate portion.

[0023] By adopting the technical scheme of the embodiment, the first plate portion is arranged obliquely, and the side surface of the microphone substrate is attached to the first plate portion. In this way, the first plate portion can realize installation and positioning of the microphone substrate, so that the microphone substrate can be installed at a preset oblique angle. In addition, the oblique angle of the first plate portion can be the oblique angle of the microphone substrate. Therefore, the oblique angle of the microphone substrate can be adjusted by adjusting the oblique angle of the first plate portion when the shell is processed.

[0024] In some embodiments, the first plate portion is located on a side of the microphone substrate away from the main body, the sound receiving opening is arranged on the first plate portion, the microphone body is arranged on a side of the microphone substrate close to the main body, and the microphone substrate is further provided with a sound receiving channel, and the microphone body communicates with the sound receiving opening through the sound receiving channel.

[0025] By adopting the technical scheme of the embodiment, the first plate portion is arranged on a side of the microphone substrate away from the main body, that is, the first plate portion is a part of the shell away from the main body. In this way, the microphone substrate and the microphone body can be closer to the front of the refrigerator, and the distance between the microphone substrate, the microphone body and the user can be shortened. The microphone body is arranged on a side of the microphone substrate close to the main body, that is, the microphone substrate is located between the microphone body and the first plate portion. In this way, the microphone substrate and the first plate portion can be attached, and the assembly difficulty of the microphone module can be reduced.

[0026] In some embodiments, the shell is provided with a limiting piece, and the limiting piece abuts against a side surface of the microphone substrate away from the first plate portion.

[0027] By adopting the technical scheme of the embodiment, the limiting piece is arranged on the shell, and the limiting piece abuts against the side surface of the microphone substrate away from the first plate portion. In this way, the relative movement between the microphone substrate and the first plate portion can be limited, so that the microphone substrate can be attached to the first plate portion.

[0028] In some embodiments, one of the shell and the microphone substrate is provided with a positioning protrusion, the other of the shell and the microphone substrate is provided with a positioning groove, and the positioning protrusion is arranged in the positioning groove.

[0029] By adopting the technical scheme of the embodiment, the positioning protrusion and the positioning groove are arranged on the shell and the microphone substrate.

It can be understood that, in the use of the refrigerator, the user is usually located on a side of the first door body 1 facing away from the main body. By abutting the microphone module 2 against the first side wall 131, the distance between the microphone module 2 and the user can be reduced, so that the microphone module 2 can be closer to the user, thereby making the microphone module 2 more accurately collect the voice instructions of the user.

[0074] In some embodiments, the first slot 13 further has a second side wall 132 parallel to the first side wall 131, and a distance between the first side wall 131 and the second side wall 132 is not less than the size of the microphone module 2. When the distance between the first side wall 131 and the second side wall 132 is equal to the size of the microphone module 2, the microphone module 2 can abut against the second side wall 132. When the distance between the first side wall 131 and the second side wall 132 is greater than the size of the microphone module 2, the microphone module 2 can be spaced apart from the second side wall 132.

[0075] With reference to Figure 5 , Figure 6 and Figure 7 , in some embodiments, the microphone module 2 comprises a microphone substrate 22 and a microphone body 23 mounted on the microphone substrate 22, and the microphone substrate 22 has a first side edge 223 and a second side edge 224 arranged along a width direction of the microphone substrate 22, wherein the first side edge 223 is located between the first door body 1 and the second side edge 224, and the microphone substrate 22 is arranged obliquely relative to the first door body 1, so that a distance between the second side edge 224 and the first door body 1 is less than the width of the microphone substrate 22.

[0076] It should be noted that the microphone substrate 22 can be a circuit board, the microphone body 23 can include a microphone, and the microphone body 23 can convert an audio signal such as a voice into an electrical signal. As an example, the microphone body 23 can be a capacitor type including a diaphragm, the microphone module 2 can include one microphone body 23, or can include a plurality of microphone bodies 23. When the microphone module 2 includes a plurality of microphone bodies 23, noise can be effectively removed, and the sound quality and recognition rate of the microphone module 2 can be improved.

[0077] It can be understood that, in general, a user usually stands in front of the refrigerator, and the microphone substrate 22 needs to be arranged towards the front of the refrigerator so that the microphone body 23 can receive voice instructions from the front of the refrigerator. By arranging the microphone substrate 22 to be inclined relative to the first door body 1, the relative distance between the side of the microphone substrate 22 away from the first door body 1 and the first door body 1 can be reduced. In this way, in the direction in which the first door body 1 points to the second door body, the size of the microphone module 2 can be reduced, thereby reducing the occupied space of the microphone module 2 in this direction, increasing the relative distance between the microphone module 2 and the second door body, and reducing the probability of collision between the microphone module 2 and the second door body.

[0078] In other embodiments, the microphone substrate 22 can also be arranged without inclination. For example, the microphone substrate 22 can be arranged vertically relative to the first door body 1, and the microphone body 23 can be arranged towards the side of the first door body 1 away from the main body. Figure 8 and Figure 9 In this embodiment, the microphone substrate 22 is perpendicular to the side of the first door body 1 facing the second door body. In this way, when a user stands in front of the refrigerator, the microphone substrate 22 can face the user, which helps to improve the sound receiving effect of the microphone module 2.

[0079] It should be noted that the side of the first door body 1 away from the main body is the front of the refrigerator. When a user stands in front of the refrigerator, the first door body 1 will block the main body when it is closed, so that the user cannot see the main body or can only see part of the main body.

[0080] For example, the microphone substrate 22 can be arranged to be inclined relative to the first door body 1, and the microphone body 23 can be arranged towards the side of the first door body 1 away from the main body. Figure 6In some embodiments, the first angle θ is formed between the microphone substrate 22 and the side of the first door body 1 facing the second door body, and 40°≤θ≤50°. It can be understood that the greater the value of θ, the greater the relative distance between the side of the microphone substrate 22 away from the first door body 1 and the first door body 1. By setting the first angle θ between the microphone substrate 22 and the side of the first door body 1 facing the second door body to be no greater than 50°, the relative distance between the side of the microphone substrate 22 away from the first door body 1 and the first door body 1 can be controlled within an appropriate range, thereby reducing the size of the microphone module 2 in the direction in which the first door body 1 points to the second door body. It can be understood that the smaller the value of θ, the more the microphone substrate 22 deviates from the front of the refrigerator. By setting the first angle θ between the microphone substrate 22 and the side of the first door body 1 facing the second door body to be no less than 40°, the extent to which the microphone substrate 22 deviates from the front of the refrigerator can be limited, which helps to improve the sound collection effect of the microphone module 2.

[0081] In some embodiments, the value of the first angle θ can be 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, or 50°.

[0082] For example, the width of the microphone substrate 22 is H3. Referring to Figure 9 When the microphone substrate 22 is not inclined, the size of the microphone substrate 22 in the direction in which the first door body 1 points to the second door body is H3. Referring to Figure 10 When the microphone substrate 22 is inclined, the size H4 of the microphone substrate 22 in the direction in which the first door body 1 points to the second door body is H3*sinθ. When the value of θ is 45°, H4≈0.71*H3.

[0083] Continuing to refer to Figure 5 In some embodiments, the microphone module 2 further includes a housing 21 connected to the first door body 1, the microphone substrate 22 and the microphone body 23 are arranged in the housing 21, and the housing 21 is provided with a sound collection opening 213 in communication with the microphone body 23. By arranging the housing 21, the microphone substrate 22 and the microphone body 23 can be installed in the housing 21. In this way, the housing 21 can integrate the microphone module 2 as a whole, facilitating the installation of the microphone module 2.

[0084] In some embodiments, the shell 21 has a first plate portion 211, which is arranged obliquely, and the side surface of the microphone substrate 22 is attached to the side surface of the first plate portion 211. By arranging the first plate portion 211 obliquely and attaching the side surface of the microphone substrate 22 to the first plate portion 211, the first plate portion 211 can realize the installation and positioning of the microphone substrate 22, so that the microphone substrate 22 can be installed at a preset oblique angle. In addition, the oblique angle of the first plate portion 211 can be the oblique angle of the microphone substrate 22, so that the oblique angle of the microphone substrate 22 can be adjusted by adjusting the oblique angle of the first plate portion 211 when the shell 21 is processed.

[0085] With reference to Figure 5 and Figure 8 , the first plate portion 211 is located on the side of the microphone substrate 22 away from the main body, the sound receiving opening 213 is arranged on the first plate portion 211, the microphone body 23 is arranged on the side of the microphone substrate 22 close to the main body, the microphone substrate 22 is further provided with a sound receiving channel 221, and the microphone body 23 is in communication with the sound receiving opening 213 through the sound receiving channel 221. By arranging the first plate portion 211 on the side of the microphone substrate 22 away from the main body, that is, the first plate portion 211 is part of the shell 21 away from the main body, so that the microphone substrate 22 and the microphone body 23 can be closer to the front of the refrigerator, and the distance between the microphone substrate 22 and the microphone body 23 and the user can be shortened. By arranging the microphone body 23 on the side of the microphone substrate 22 close to the main body, that is, the microphone substrate 22 is located between the microphone body 23 and the first plate portion 211, the microphone substrate 22 and the first plate portion 211 can be easily attached, thereby reducing the assembly difficulty of the microphone module.

[0086] In some embodiments, the sound receiving channel 221 is arranged at the middle portion of the microphone substrate 22, and the diameter of the sound receiving channel 221 can be 2 mm.

[0087] With reference to Figure 10 In some embodiments, the shell 21 is provided with a limiting piece 214, and the limiting piece 214 abuts against the side surface of the microphone substrate 22 away from the first plate portion 211. By arranging the limiting piece 214 on the shell 21 and abutting the limiting piece 214 against the side surface of the microphone substrate 22 away from the first plate portion 211, the relative movement between the microphone substrate 22 and the first plate portion 211 can be limited, so that the microphone substrate 22 can be kept attached to the first plate portion 211.

[0088] In some embodiments, the microphone substrate 22 and the first plate portion 211 can also be bonded by glue, so as to reduce the shaking between the microphone substrate 22 and the shell 21. In other embodiments, the microphone substrate 22 and the shell 21 can also be connected by screws.

[0089] With reference toFigure 10 And Figure 11 In some embodiments, the shell 21 is provided with positioning protrusions 215, and the microphone substrate 22 is provided with positioning grooves 222. In other embodiments, the shell 21 is provided with positioning grooves 222, and the microphone substrate 22 is provided with positioning protrusions 215, and the positioning protrusions 215 are arranged in the positioning grooves 222. By arranging the positioning protrusions 215 and the positioning grooves 222 on the shell 21 and the microphone substrate 22, the shell 21 and the microphone substrate 22 can be positioned when the positioning protrusions 215 and the positioning grooves 222 are inserted, thereby facilitating the installation of the shell 21 and the microphone substrate 22 and reducing the assembly difficulty of the microphone module 2.

[0090] Referring to Figure 12 And Figure 13 In some embodiments, the microphone module 2 can be fixed to the first door body 1 by screws. For example, the first door body 1 can be provided with threaded holes 16, and the shell 21 can be provided with mounting holes 216. The screws can be screwed into the threaded holes 16 through the mounting holes 216. The connection between the microphone module 2 and the first door body 1 can be stable by using screws.

[0091] In the present embodiment, the shell 21 further comprises a second plate portion 212. For example, the shell 21 can be provided with four second plate portions 212, and one first plate portion 211 and the four second plate portions 212 are connected to form the shell 21 with an opening. When the shell 21 is connected to the first door body 1, the first door body 1 can block the opening of the shell 21. In other embodiments, the shell 21 can further comprise a third plate portion (not shown in the figure). The third plate portion can be connected to the first plate portion 211 and the second plate portion 212 to block the opening of the shell 21.

[0092] In some embodiments, the thickness of the shell 21 is K, and the diameter of the sound collecting channel 221 can be 2 mm. The first door body 1 and the second door body are arranged in the vertical direction. Referring to Figure 9 , the microphone substrate 22 is vertically placed. In the vertical direction, the size of the microphone module 2 protruding from the first groove 13 can be 0.5*H3+1 mm+K. When the shell 21 does not comprise a third plate portion, and the microphone substrate 22 abuts against the groove bottom of the first groove 13, the size of the microphone module 2 embedded in the first groove 13 can be 0.5*H3-1 mm. When the shell 21 comprises a third plate portion, and the two sides of the third plate portion abut against the groove bottom of the first groove 13 and the microphone substrate 22 respectively, the size of the microphone module 22 embedded in the first groove 13 can be 0.5*H3-1 mm+K. Figure 6, the microphone substrate 22 is placed obliquely relative to the vertical direction, and in the vertical direction, the size of the microphone module 2 protruding from the first slot 13 can be (0.5*H3+1mm)*sinθ+K, when θ=45°, the size of the microphone module 2 protruding from the first slot 13 is about 0.71*(0.5*H3+1mm)+K.

[0093] In some embodiments, the first door body 1 includes an end plate 12, and the microphone module 2 can be fixed to the end plate of the first door body by screws.

[0094] Continuing to refer to Figure 12 and Figure 13 In some embodiments, the first door body 1 further includes a second slot 14 on the side facing the empty area, and a voice module 3 is arranged in the second slot 14, and the voice module 3 is in communication connection with the microphone module 2.

[0095] It should be noted that the voice module 3 can further convert the electrical signal generated by the microphone module 2 into an input readable by the controller, such as a binary code or a character sequence, so that the controller of the refrigerator can extract the relevant information of the user's voice instruction and generate a corresponding response action.

[0096] It should be noted that the voice module 3 is in communication connection with the microphone module 2, and the communication connection can be achieved by wired means such as wires, or by wireless means such as Bluetooth, Wi-Fi, mobile network, etc. The electrical signal generated by the microphone module 2 can be transmitted to the voice module 3, and the voice module 3 can process the electrical signal after receiving the electrical signal from the microphone module 2, and generate a signal that can be recognized by the controller of the refrigerator.

[0097] In some embodiments, the side wall or the slot bottom of the second slot 14 can further be provided with a through hole 141, and the signal line of the voice module 3 can extend into the interior of the first door body 1 through the through hole 141, so that the voice module 3 can be connected with the controller arranged in the first door body 1.

[0098] In some embodiments, the second slot 14 can be in communication with the first slot 13, the wire harness of the microphone module 2 can extend into the second slot 14 and be connected with the voice module 3 arranged in the second slot 14, and in addition, the wire harness of the microphone module 2 can also extend into the interior of the first door body 1 through the through hole 141 and be connected with the controller arranged in the first door body 1.
