[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model discloses a tea bar machine for improving voice recognition rate, comprising a cabinet and a back plate arranged on the top of the cabinet, a voice module is arranged on the back plate, the voice module comprises a sound receiving device for collecting voice information, a high-power heating area is arranged on the cabinet, an installation area for installing and fixing the sound receiving device is also arranged in the back plate, and the installation area is located on a side of the back plate away from the high-power heating area.

[0030] In the above, the tea bar machine includes a cabinet for accommodating a water storage container, and a back panel arranged on the top of the cabinet. The voice module is arranged on the back panel for collecting voice information, wherein the setting height of the back panel relative to the cabinet is relatively close to the user's voice position, so as to facilitate the recognition of the voice information emitted by the user. The voice module includes a sound receiving device for collecting voice information. An installation area is arranged inside the back panel, and the sound receiving device is installed and fixed in the installation area. A high-power heating area is arranged on the cabinet for heating the water collection container placed therein. During the water collection and heating process, the water storage container in the high-power heating area will generate certain noise when taking in water and boiling water. This noise will interfere with the sound receiving device installed on the back panel, resulting in the presence of some useless interference signals in the voice received by the sound receiving device, reducing its recognition rate of the user's voice, causing processing delays or even misoperation, and affecting the user's experience. In this embodiment, the sound receiving device is fixed in the installation area, and the installation area is set on the side away from the high-power heating area to reduce noise interference and improve the recognition accuracy of the user's voice information by the sound receiving device, so that the voice module can more clearly identify the work instructions in the voice information, execute the work process required by the user, and improve the user's experience.

[0031] In detail, Figure 1As shown, the utility model provides a tea bar machine for improving voice recognition rate, including a back panel 1 and a cabinet 2, the back panel 1 is installed on the rear side of the top of the cabinet 2, and a high-power heating area 21 is provided on one side of the top of the cabinet 2 for placing a water storage container 3, a first installation area 11 is provided on the back panel 1, and a sound receiving device for receiving user commands is provided in the first installation area 11, wherein the first installation area 11 is distributed on a side away from the high-power heating area 21. Specifically, if the high-power heating area 21 is provided on the right side of the top of the cabinet 1, the first installation area 11 is provided on the left side of the top of the back panel 1, and the position is away from the high-power heating area 2 1 and the needs of the water storage container 3 at work, which reduces the influence of the noise and steam generated by the water storage container 3 during the process of adding water and boiling water on the radio device. On the contrary, if the high-power heating area 21 is set on the left side of the top of the cabinet 1, the first installation area 11 can be set on the right side of the top of the back plate 1. If the high-power heating area 21 is set in the middle position of the top of the cabinet 1, the first installation area 11 can be set on the left or right side of the top of the back plate 1. The first installation area 11 in this embodiment is set away from the high-power heating area 21. The specific setting position is determined according to the location of the high-power heating area 21 on the tea bar machine, and is not limited in this embodiment.

[0032] In this embodiment, Figure 2 As shown, a mounting bracket 12 is provided on the front side of the back panel 1, and the mounting bracket 12 is provided below the mounting area. The mounting bracket 12 protrudes toward the outside of the back panel 1 to cut off the connection between the high-power heating area 11 and the mounting area. Specifically, the mounting bracket 12 is provided on the front side of the back panel 1 near the top, and the mounting area is distributed near the mounting bracket 12. The high-power heating area 11 is located at a relatively far position below the mounting bracket 12. The high-power heating area 11 and the mounting area are separated by the protruding mounting bracket 12. The steam generated during the boiling water process is blocked by the mounting bracket to prevent it from entering the radio device and affecting the life of the device. At the same time, it can isolate some noise, further improving the recognition rate of the tea bar machine to the user's voice commands.

[0033] In detail, Figure 2As shown, the mounting bracket 12 includes a blocking portion 121 protruding toward the outside of the back panel, and the blocking portion cooperates with the back panel 1 to form a soundproof cavity, wherein the blocking portion is used to block the connection line between the high-power heating area 11 and the mounting area, and the blocking portion 121 partially overlaps with the high-power heating area 11 in the vertical projection, so as to achieve partial coverage of the water storage container 3, and reduce the influence of the water storage container 3 on the sound receiving device when working. At the same time, the blocking portion 121 is a hollow structure design to cooperate with the back panel to form a soundproof cavity. In this embodiment, a cavity layer is formed between the high-power heating area 11 and the mounting area through the setting of the soundproof cavity. Based on the fact that sound energy propagates in different media, namely "solid-gas-solid", the propagation will greatly consume its own energy, thereby achieving further weakening of the noise generated by the water storage container 3. At the same time, the hollow design of the mounting bracket 12 reduces the overall weight of the back panel, can reduce the shaking of the back panel, and enhance the stability of the tea bar machine.

[0034] In the specific implementation of this embodiment, Figure 2 As shown, a mounting bevel 122 for mounting the panel assembly 4 is provided on the front side of the mounting bracket 12, so that the panel assembly is tilted toward the high-power heating area, wherein the mounting bracket 12 is also used to mount the panel assembly 4, and the panel assembly 4 includes functions such as display and user manual operation, wherein a plurality of mounting holes 123 are provided on the mounting bevel 122, which cooperate with the mounting structure provided on the panel assembly 4 to fix the panel assembly 4. In this embodiment, the mounting surface on the front side of the mounting bracket 12 is designed as a bevel, so that the panel assembly 4 is fixed as a tilted design toward one side, which is convenient for user observation and operation, and avoids the steam generated by the hot water in the water storage container 3 directly blowing the panel assembly 4 and affecting the display clarity. At the same time, the tilted design toward the high-power heating area 11 expands the coverage area of ​​the mounting bracket 12 on the high-power heating area 11, strengthens the blocking ability of the mounting bracket 12, and further reduces the noise generated by the water storage container 3 during the process of adding water and boiling water.

[0035] In another implementation of this embodiment, Figure 3As shown, a low-power heating area 22 is also provided on the cabinet, and the high-power heating area 11 and the low-power heating area 22 are located on both sides of the top of the cabinet 2. At this time, the installation area is set in the middle position of the top of the back panel 1, that is, a second installation area 13 is set in the middle position of the top of the back panel 1. The left or right side of the top of the back panel 1 is too close to one of the high-power heating area 11 and the low-power heating area 22, and is easily disturbed by noise. In order to take into account the heating areas on the left and right sides, the middle position of the top of the back panel 1 becomes the farthest position away from the two heating areas at the same time. In this embodiment, the second installation area 13 is set at this position to minimize the influence of the noise generated in the two heating areas on the sound receiving effect of the sound receiving device. Specifically, since heating areas are provided on both sides of the top of the cabinet 2, the mounting bracket 12 needs to simultaneously block the connection line between the high-power heating area 11, the low-power heating area 22 and the second mounting area 13, that is, the blocking portion 121 partially overlaps with the high-power heating area 11 and the low-power heating area 22 in the vertical projection, so as to achieve partial coverage of multiple water storage containers 3, and at the same time reduce the influence of the water storage containers 3 distributed on both sides of the top of the cabinet 2 on the sound receiving device when working.

[0036] In this embodiment, Figure 4 As shown, the back panel 1 includes a back panel front shell 14 and a back panel rear shell 15. The sound receiving device is arranged on the back panel rear shell. At least one sound receiving hole corresponding to the sound receiving device is arranged on the back panel front shell. Specifically, the sound receiving device and the sound receiving hole are both arranged in the installation area. The sound receiving device can be a microphone installed inside the back panel 1. The microphone obtains the user's voice information through the sound receiving hole and processes it. In this embodiment, by setting the sound receiving hole, the sensitivity and speed of the sound receiving device in receiving voice commands are improved, and the sound receiving effect is improved. In a specific implementation of this embodiment, the back panel front shell is provided with a plurality of sound receiving holes, and the sound receiving holes are arranged in a dot matrix to form a circular or polygonal sound receiving area. By setting a plurality of sound receiving holes, the sound receiving effect of the sound receiving device is further improved. At the same time, the number of microphones can be increased, and the collection effect, collection range and recognition accuracy of voice information can be improved.

[0037] In a specific implementation of this embodiment, the aperture of the sound receiving hole is set to 1.5mm-3mm. In order to prevent foreign objects or mosquitoes and other factors from clogging the sound receiving hole and causing the sound receiving function to fail, the aperture of the sound receiving hole should not be too large. In this implementation, the aperture is limited to within 3mm. At the same time, if the aperture of the sound receiving hole is too small, it will affect the sound receiving effect, resulting in the sound receiving device being unable to collect the user's complete voice information. To ensure the sound receiving effect, the minimum aperture is limited to above 1.5mm.

[0038] In this embodiment, refer to Figure 5, an annular convex rib is also provided in the installation area, the annular convex rib is provided on the back plate front shell 15, and extends toward the back plate rear shell 15 to form an installation groove 16, the installation groove 16 cooperates with the back plate rear shell 15 to form a receiving cavity, wherein the sound receiving device is embedded in the receiving cavity, and the sound receiving device can be fixed in the installation groove 16 by a detachable connection method such as interference plugging, gluing, snap connection, screw connection, etc. In this embodiment, by providing the installation groove 16, the sound receiving device is fixed inside the back plate 1, its installation reliability is enhanced, and it is convenient to collect the user's voice information.

[0039] In this embodiment, the voice module also includes a sound output component and an electronic control board. The sound output component and the sound receiving device are both electrically connected to the electronic control board. The electronic control board is installed inside the back panel 1, wherein the sound output component is used to broadcast the corresponding voice prompts of the tea bar machine so that the user can obtain information feedback, and the electronic control board is used to process the voice instructions of the sound receiving device and send voice broadcast information to the sound output component. The electronic control board and the sound output component are both arranged inside the back panel 1, and the sound output component is arranged on the side away from the sound receiving device, that is, on the rear side of the back panel 1, so as to prevent the voice broadcast emitted by the sound output component from affecting the voice information acquisition of the sound receiving device.
