Description

Technical Field

[0001] This application relates to the field of household water heater equipment, and in particular to an integrated ultrasonic dual flow meter. Background Technology

[0002] An ultrasonic heat meter is a device used to accurately measure the heat energy consumption in a heat exchange system. It is widely used for measuring hot water consumption and monitoring energy efficiency in household water heaters.

[0003] Chinese invention patent application CN102706485A discloses a dual-flowmeter ultrasonic heat meter, including an inlet water flow sensor, a return water flow sensor, an inlet water temperature sensor, a return water temperature sensor, and an integrator. When the dual-flowmeter ultrasonic heat meter is working, the inlet water flow sensor transmits the flow rate at the inlet pipe to the integrator as an electrical signal, and simultaneously, the outlet water flow sensor transmits the flow rate at the outlet pipe to the integrator as an electrical signal. The integrator collects, compares, and calculates the electrical signals, and the difference indicates the amount of water lost by the user. The inlet water flow sensor, the return water flow sensor, the inlet water temperature sensor, and the return water temperature sensor are all connected to the integrator via data cables.

[0004] Regarding the aforementioned technologies, the inventors believe that the exposed data cables used to connect the sensor and the integrator are rather messy. Utility Model Content

[0005] To address the issue of messy exposed data cables used to connect the sensor and integrator, this application provides an integrated ultrasonic dual flow meter.

[0006] The integrated ultrasonic dual flow meter provided in this application adopts the following technical solution:

[0007] An integrated ultrasonic dual flow meter includes two ultrasonic flow meters and an integrator electrically connected to the ultrasonic flow meters; it also includes a mounting housing having a mounting chamber for arranging the integrator; the bottom of the mounting housing has mounting slots corresponding one-to-one with the ultrasonic flow meters for arranging the ultrasonic flow meters; the mounting housing is also provided with a locking plate for covering the opening of the mounting slots; and the bottom surface of the mounting slots has a communication through hole communicating with the mounting chamber.

[0008] By adopting the above technical solution, when the integrated ultrasonic dual flow meter is working, the two ultrasonic flow meters will transmit the flow rate in the form of electrical signals to the integrator installed in the installation chamber. The integrator will process the electrical signals, and the difference obtained can indicate the user's water loss. The setting of the communication through hole realizes the electrical connection between the ultrasonic flow meter and the integrator, and at the same time helps to arrange the data cable inside the installation chamber, thereby improving the problem of the data cable being exposed and messy.

[0009] Optionally, the outer wall of the locking plate is provided with first buckles on both sides for locking the locking plate into the mounting slot, and the mounting slot has first slots on both sides for locking by the first buckles.

[0010] By adopting the above technical solution, a first buckle is set on the outside of the locking plate, and a first slot that cooperates with the first buckle is set on both sides of the groove of the mounting through groove, which helps to clamp and lock the ultrasonic flow meter between the mounting through groove and the locking plate.

[0011] Optionally, the number of the first buckles is four, and they are symmetrically arranged in pairs on both sides of the outer wall of the locking plate; the mounting slot has four first slots that cooperate with the four first buckles one by one.

[0012] By adopting the above technical solution, the first buckles are symmetrically arranged in pairs on the outer wall of the locking plate, and four first slots corresponding to the first buckles are set on the side wall of the mounting through groove. This helps to further improve the installation firmness between the mounting through groove and the locking plate, thereby helping to reduce the probability of ultrasonic flow meter axial movement.

[0013] Optionally, the mounting housing includes a main housing for arranging the mounting chamber and an upper cover plate arranged on top of the main housing for covering the mounting chamber. The mating surface of the upper cover plate has a second buckle for locking the upper cover plate to the main housing, and the surface of the main housing is provided with a second slot for locking by the second buckle.

[0014] By adopting the above technical solution, an upper cover plate is arranged on the top of the main housing, and a second buckle is set on the mating surface of the upper cover plate. A second slot that cooperates with the second buckle to lock is set on the surface of the main housing. This realizes that the upper cover plate can cover the installation chamber as a whole, which helps to improve the installation firmness between the main housing and the upper housing.

[0015] Optionally, the bottom of the mounting housing is provided with a lower cover plate for integrally covering the locking plate and the mounting housing. The mating surface of the lower cover plate has a third buckle for locking the lower cover plate to the mounting housing. The surface of the mounting housing is provided with a third slot for locking the third buckle. The lower cover plate and the upper cover plate are fixed together by bolts.

[0016] By adopting the above technical solution, a lower cover plate is provided at the bottom of the mounting housing, and a third buckle is provided on the mating surface of the lower cover plate. A third slot for locking the third buckle is provided at the bottom of the mounting housing, so as to achieve the integral covering of the locking plate and the mounting housing, which helps to improve the connection between the mounting housing and the locking plate. The upper cover plate and the lower cover plate are locked by bolts, which helps to further improve the installation firmness between the main housing and the upper cover plate.

[0017] Optionally, the outer wall of the ultrasonic flow meter has an ultrasonic mounting base facing the bottom of the mounting slot. The ultrasonic mounting base is arranged opposite the communication through hole. The outer wall of the ultrasonic flow meter has a positioning screw for cooperating with the ultrasonic mounting base. The bottom of the mounting chamber has a positioning through hole that cooperates with the positioning screw. The positioning screw is also equipped with a positioning nut for locking with the mounting housing.

[0018] By adopting the above technical solution, when installing the ultrasonic flow meter into the installation slot, first insert the positioning screw into the positioning through hole at the bottom of the installation chamber. At this time, the ultrasonic mounting base is aligned with the communication through hole. Then, install the positioning nut onto the positioning screw and lock it in place. This achieves the cooperative installation of the ultrasonic flow meter and the mounting housing, which helps to further prevent the ultrasonic flow meter from moving around in the installation slot.

[0019] Optionally, each ultrasonic mounting base has two positioning screws, which are arranged symmetrically about the ultrasonic mounting base.

[0020] By adopting the above technical solution, two corresponding positioning screws are set on both sides of each ultrasonic mounting base, and the two positioning screws are arranged symmetrically from left to right, which helps to further improve the installation stability of the ultrasonic flow meter in the mounting groove.

[0021] Optionally, the housing of the integrator is provided with a limiting hole, and the bottom of the mounting chamber has a limiting post for accommodating the limiting hole.

[0022] By adopting the above technical solution, a limiting hole is provided in the outer shell of the integrator, and a limiting post is provided in the installation chamber for the arrangement of the limiting hole, thus realizing the fixed installation of the integrator in the installation chamber.

[0023] Optionally, the number of limiting holes is four and they are symmetrically arranged on both sides of the integrator, and the bottom of the mounting chamber has four limiting posts that are directly opposite the four limiting holes.

[0024] By adopting the above technical solution, four limiting holes are symmetrically arranged around the outer shell of the integrator, and four limiting posts are symmetrically arranged at the bottom of the installation chamber, each corresponding to one of the four limiting holes. This helps to improve the installation stability of the integrator in the installation chamber.

[0025] Optionally, the upper cover plate has a square opening facing the integrator for display on the integrator's screen, and a transparent cover plate is fitted into the square opening.

[0026] By adopting the above technical solution, a square opening is made at the top of the upper cover plate and a transparent cover plate that matches it is installed at the square opening. This helps the upper cover plate to seal the installation chamber without affecting the display function of the integrator.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the integrated ultrasonic dual flow meter is working, the two ultrasonic flow meters will transmit the flow rate in the form of electrical signals to the integrator installed in the installation chamber. The integrator will process the electrical signals, and the difference obtained can indicate the user's water loss. The communication through hole realizes the electrical connection between the ultrasonic flow meter and the integrator, and at the same time helps to arrange the data cable inside the installation chamber, improving the problem of the data cable being exposed and messy.

[0029] 2. By setting a first buckle on the outside of the locking plate and setting a first slot on both sides of the groove of the mounting groove to cooperate with the first buckle, it is helpful to clamp and lock the ultrasonic flow meter between the mounting groove and the locking plate.

[0030] 3. By setting two corresponding positioning screws on both sides of each ultrasonic mounting base and arranging the two positioning screws symmetrically, the installation stability of the ultrasonic flow meter in the mounting slot can be further improved. Attached Figure Description
