Description

Technical Field

[0001] This utility model relates to the field of water tanks, and in particular to a defrosting water tank that can shield against interference. Background Technology

[0002] The defrosting tank uses ultrasonic transducers to defrost frozen foods. Since these transducers require circuit control and continuous power, their accompanying circuit board is typically installed together with the transducer. This layout makes it easy for the radiation and electromagnetic interference signals generated by the ultrasonic waves to be transmitted to the circuit board. This can not only significantly increase ultrasonic noise but also interfere with the normal operation of the circuit, potentially damaging the circuit board and affecting the stability and lifespan of the equipment.

[0003] Based on the above, the existing thawing tanks need further improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a defrosting water tank that can shield interference. The ultrasonic transducer is installed on the lower side of the water tank through the mounting base, and the circuit board is installed on one side of the mounting base through the outer shell. This can effectively prevent the radiation and electromagnetic interference signals generated during ultrasonic operation from being transmitted to the circuit board, thereby extending the stability and service life of the equipment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a thawing water tank capable of shielding interference, comprising a tank body; a water outlet assembly disposed on one side of the tank body; a drainage assembly disposed on the lower side of the tank body and communicating with the tank body; and a thawing assembly comprising an ultrasonic transducer, a mounting base, and an electrical control structure. The ultrasonic transducer is disposed on the lower side of the tank body, the mounting base is configured as an open cavity surrounding the ultrasonic transducer, and the electrical control structure is disposed on one side of the mounting base, comprising a housing and a circuit board, the circuit board being installed inside the housing.

[0006] This invention uses a mounting base to fix the ultrasonic transducer to the bottom of the water tank, while placing the circuit board inside the housing and mounting it on one side of the mounting base. This structure effectively shields the circuit board from radiation and electromagnetic interference signals generated during ultrasonic operation, thus preventing interference or damage to the circuit board. Compared with existing technologies, the interference-shielding thawing water tank used in this invention significantly improves the circuit board's anti-interference capability, helping to extend the equipment's service life and operational stability.

[0007] Preferably, the mounting base has a stepped first mounting part on the side near the electronic control structure. The first mounting part and the side wall of the mounting base form a first mounting position, and the electronic control structure is disposed at the first mounting position. The first mounting position makes the contact surface between the mounting base and the electronic control structure larger, so that there is more space between the two for connection, fixation and communication.

[0008] Preferably, the electronic control structure has a mounting hole on the side near the mounting base, and the electronic control structure is connected to the mounting base by screws; during assembly, the screws pass through the mounting hole, making the connection between the electronic control structure and the mounting base more stable.

[0010] Preferably, the edge of the second housing is provided with a "┖"-shaped extension, which forms a slot with the outer wall of the second housing, and the edge of the first housing is inserted into the slot; the slot allows the first housing and the second housing to be quickly aligned.

[0011] Preferably, the first housing is provided with a fixed base, and the circuit board is provided with a fixing pin on the side near the first housing. The fixing pin is inserted into the fixed base. The fixed base and the fixing pin fix the circuit board on the first housing, preventing the circuit board from tilting and causing the connecting wires to become taut or bent, which could lead to wire breakage or wear.

[0012] Preferably, the mounting base has a stepped second mounting part on the side opposite to the mounting part, and the first and second mounting parts are provided with positioning holes for connection with the slot screws; the positioning holes are located at the four corners of the mounting base.

[0013] Preferably, the groove body has a transducer mounting area protruding into the inner cavity, and the ultrasonic transducer is mounted on the lower side of the transducer mounting area via a mounting plate.

[0014] Preferably, the first housing is provided with a first positioning groove, and the second housing is provided with a second positioning groove, with the first positioning groove corresponding to the second positioning groove; the first positioning groove and the second positioning groove are used to install fastening screws, so that the fastening screws are hidden inside the first housing and the second housing, and the fastening screws do not affect the overall aesthetics of the housing.

[0015] Preferably, the outer side of the first housing is provided with a protrusion, which is correspondingly provided with the fixed base or provided in the middle of the first housing; the fixing pin passes through the side wall of the first housing to the protrusion corresponding to the fixed base, so that the circuit board is more firmly connected to the first housing, and the protrusion provided in the middle of the first housing is used to connect with the circuit board.

[0016] Preferably, the fixing base is designed in the shape of an "I"; the fixing base is arranged on the four sides close to the side wall of the first housing. The "I" shape design can prevent the fixing base from rotating and causing the fixing pin to loosen, which in turn leads to unstable circuit board connection.

[0017] Preferably, the mounting hole is strip-shaped, allowing for fine-tuning of the electrical control structure's installation position by adjusting the screws on the mounting hole during installation, thus ensuring more accurate installation of the electrical control structure.

Detailed Implementation

[0029] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "horizontal", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0030] See Figures 1 to 7 This embodiment discloses a thawing water tank 1 capable of shielding interference, including a tank body 7; a water outlet assembly 11, which is disposed on one side of the tank body 7; a drainage assembly 9, which is disposed on the lower side of the tank body 7 and communicates with the tank body 7; and a thawing assembly 1, which includes an ultrasonic transducer 8, a mounting base 2, and an electrical control structure 3. The ultrasonic transducer 8 is disposed on the lower side of the tank body 7, and the mounting base 2 is a concave cavity with an open top that surrounds the ultrasonic transducer 8. The electrical control structure 3 is disposed on one side of the mounting base 2 and includes a housing 4 and a circuit board 5, with the circuit board 5 installed inside the housing 4.

[0031] See Figures 3 to 9 The mounting base 2 has a stepped first mounting portion 21 on the side near the electronic control structure 3. The first mounting portion 21 and the side wall of the mounting base 2 form a first mounting position 22, and the electronic control structure 3 is mounted on the first mounting position 22. In this design, the first mounting portion 21 makes the contact surface between the mounting base 2 and the electronic control structure 3 "L"-shaped, increasing the contact area between the two and providing a larger area for connection and communication, resulting in a more stable connection.

[0032] See Figure 8 The electronic control structure 3 has a mounting hole 31 on the side near the mounting base, and the electronic control structure 3 is connected to the mounting base 2 by screws. The mounting hole 31 is strip-shaped. The mounting hole 31 in this design allows the electronic control structure 3 to be finely adjusted on the mounting base 2 during installation by adjusting the position of the screws in the mounting hole 31, so that the position of the electronic control structure 3 is more in line with the first installation position 22.

[0033] See Figure 5 To enable rapid assembly of the outer casing 4, the outer casing 4 includes a first housing 41 and a second housing 42. Both the first housing 41 and the second housing 42 are recessed cavities, and together they form a control cavity 43. The mounting hole 31 is provided on the first housing 41, and the circuit board 5 is disposed within the control cavity 43. In this design, the outer casing 4 separates the circuit board 5 from the ultrasonic transducer 8 by two sidewalls, preventing the radiation and electromagnetic wave signals from the ultrasonic transducer 8 from interfering with the circuit board 5, thus ensuring stable operation of the circuit board 5.

[0034] See Figures 1 to 7The second housing 42 has a "┖"-shaped extension 421 along its edge, which forms a slot 422 with the outer wall of the second housing 42. The edge of the first housing 41 is inserted into the slot 422. The slot 422 in this design allows for quick alignment of the first housing 41 and the second housing 42, making installation convenient.

[0035] See Figure 8 The first housing 41 contains a fixed base 412, and the circuit board 5 has a fixing pin 5 on the side near the first housing 41. The fixing pin 51 is inserted into the fixed base 412. The fixed base 412 is in the shape of an "I". Specifically, the fixed base 412 is distributed around the perimeter of the side wall of the first housing 41. The "I"-shaped fixed base 412 in this design is restricted by the surface connected to the side wall, preventing it from rotating at a large angle, effectively preventing the circuit board 5 from becoming loose due to loosening between the fixed base 412 and the fixing pin 51.

[0036] See Figure 4 and Figure 9 The mounting base 2 has a stepped second mounting portion 23 on the side opposite to the first mounting portion 21. The first mounting portion 21 and the second mounting portion 23 are provided with positioning holes 24, which are used for screw connection with the groove body 7. Specifically, the positioning holes 24 are located at the four corners of the mounting base 2.

[0037] See Figures 2 to 3 The groove 7 has a transducer mounting area 71 protruding into the inner cavity, and the ultrasonic transducer 8 is mounted on the lower side of the transducer mounting area 71 via the mounting plate 10.

[0038] See Figures 5 to 8 The first housing 41 has a first positioning groove 411, and the second housing 42 has a second positioning groove 423, with the first positioning groove 411 and the second positioning groove 423 corresponding to each other. Specifically, the first positioning groove 411 and the second positioning groove 423 extend along the width direction of the first housing 41 and the second housing 42, respectively. In this design, the first housing 41 and the second housing 42 are connected by fastening screws, which are hidden within the first positioning grooves 411 and the second positioning grooves 423, achieving a concealed installation effect and maintaining the overall uniformity of the outer shell 4.

[0039] See Figures 6 to 8 The first housing 41 has a protrusion 413 on its outer side. The protrusion 413 is correspondingly provided with the fixed base 412, or is provided in the middle of the first housing 41. In this design, the protrusion 413 corresponding to the fixed base 412 allows the fixing pin 51 to pass through the side wall of the first housing 41, making the connection with the first housing 41 more secure. The protrusion 413 in the middle of the first housing 41 is used to connect with the circuit board 5.

[0040] See Figures 4 to 9 In order to enable the circuit board 5 to be powered, the first mounting part 21 and the top wall of the first housing 41 are provided with a through hole 6.

[0041] This invention uses a mounting base 2 to fix the ultrasonic transducer to the bottom of the water tank, while placing the circuit board 5 inside the outer casing 4 and mounting it on one side of the mounting base 2. This structure effectively shields the radiation and electromagnetic interference signals generated during ultrasonic operation from being transmitted to the circuit board 5, thereby preventing the circuit board 5 from being interfered with or damaged. Compared with the prior art, the interference-shielding thawing water tank 1 used in this invention significantly improves the anti-interference capability of the circuit board 5, helping to extend the service life and operational stability of the equipment.
