Description

TECHNICAL FIELD

[0001] The utility model relates to electric hot water bucket technical field, concretely is a temperature controller temperature sensing probe fixing structure for electric hot water bucket. BACKGROUND

[0002] The temperature sensing probe fixing structure of electric hot water bucket ensures that the temperature sensor can accurately and stably measure water temperature, thereby realizing real-time monitoring and adjustment of water temperature, which is generally arranged on the inner wall of the inner container of the water bucket or the bottom of the bucket, and comprises a fixing seat, a probe support, a sealing ring, a connecting line and a mounting hole, the fixing seat is made of high-temperature-resistant and corrosion-resistant material (such as stainless steel or high-heat-resistant plastic) as the basis of the temperature sensing probe, which ensures that it can be stably installed inside the water bucket. The contact mode of the fixing seat and the water bucket must be scientific to maintain the firmness and good contact of the probe and avoid the interference of temperature measurement caused by water flow or bubbles generated during the heating process. The probe support serves to connect the probe and the fixing seat, and is usually made of metal or high-strength plastic, and the design needs to ensure that the probe can freely stretch in water without hindering water flow. However, the temperature sensing probe fixing structure at the present stage is generally a single-probe support structure, which is applied to large-specification electric hot water buckets, and the volume of the water body is large, so the single-fixed-position temperature sensing probe is prone to being too close or too far from the heat source. If the probe is installed too close to the heat source, the temperature measured by the probe will be higher than the actual average temperature of the water body, thereby causing the control system to stop heating too early, resulting in that the water temperature does not reach the ideal temperature set by the user. On the contrary, if the probe is too far from the heat source, the measured temperature may be lower than the actual water temperature, resulting in prolonged heating time and affecting the user's experience.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] Please refer to Figures 1-5 , the utility model provides an embodiment: a temperature sensing probe fixing structure for temperature controller of electric hot water bucket, including cover bottom cover 1 and bottom setting hollow part 2, both sides of cover bottom cover 1 bottom wall are rotatably installed with reference shaft 3, two reference shafts 3 are installed with gear transmission part 4 for keeping power transmission, one end of reference shaft 3 surface is fixed with right angle arm 6, the opposite side outer wall of two right angle arms 6 is fixed with temperature sensing head rod sleeve 7, temperature sensing head rod sleeve 7 is for temperature controller temperature sensing probe sleeve, the central position at temperature sensing head rod sleeve 7 bottom end is provided with the through hole 703 for temperature controller temperature sensing probe to go out, the inner wall on one side of cover bottom cover 1 is installed with rotary self-locking driving mechanism 5 for driving one reference shaft 3 rotation;

[0019] The outer edge at cover bottom cover 1 top end is fixed with flange plate 101, and cover bottom cover 1 is bolted with electric hot water bucket barrel top wall through flange plate 101;

[0020] The rotating self-locking driving mechanism 5 comprises a lug plate installed on the inner wall of one side of the cover bottom cover 1 and a worm gear reduction motor installed on the top end of the lug plate. The output end of the worm gear reduction motor is fixedly connected with the top end of one of the reference shafts 3. The gear transmission member 4 comprises gear plates fixed on the two reference shafts 3. The two gear plates are in mesh with each other. When the rotating self-locking driving mechanism 5 is started, the rotating force is transmitted to the two reference shafts 3 through the cooperation of the gear transmission member 4, so that the right-angle arm 6 can be deflected around the reference shaft 3.

[0021] The rotating self-locking driving mechanism 5 can automatically lock the right-angle arm 6 when the temperature sensing probe reaches the required position, ensuring the stability of the probe position. The self-locking mechanism avoids accidental changes in the probe position caused by vibration or external interference, ensuring the reliability of the temperature measurement process.

[0022] One end of the surface of the temperature sensing head rod sleeve 7 is fixedly provided with a convex edge 701. The lower surface of the convex edge 701 is in contact with the upper surface of the right-angle arm 6. The upper surface of the convex edge 701 is provided with a plurality of internally threaded holes 702 which are completely penetrated downward. An arc-shaped recess for embedding the temperature sensing head rod sleeve 7 is arranged on the outer wall of one side of the right-angle arm 6. The diameter of the arc-shaped recess is equal to the outer diameter of the temperature sensing head rod sleeve 7. The reference shaft 3 serves as a support point to provide support for the subsequent rotation of the right-angle arm 6 and the temperature sensing head rod sleeve 7. When the temperature sensing head rod sleeve 7 is installed with the right-angle arm 6, the lower surface of the convex edge 701 is in contact with the upper surface of the right-angle arm 6. The convex edge 701 and the right-angle arm 6 are connected by bolts. In this way, the right-angle arm 6 and the temperature sensing head rod sleeve 7 can rotate around the reference shaft 3.

[0023] A vertically arranged wiring structure 8 is arranged on the outer wall of the side of the temperature sensing head rod sleeve 7 away from the right-angle arm 6. The vertically arranged wiring structure 8 comprises a wire outlet pipe 801 integrally formed on the outer wall of one side of the temperature sensing head rod sleeve 7 and an annular through portion 802 arranged inside the wire outlet pipe 801. The annular through portion 802 allows the temperature sensing head rod sleeve 7 and the wire outlet pipe 801 to communicate with each other. The probe can freely adjust its position in the water under the guidance of the temperature sensing head rod sleeve 7. The wire outlet pipe 801 communicates with the temperature sensing head rod sleeve 7 through the annular through portion 802. At this time, the guide at the top end of the probe can be introduced into the wire outlet pipe 801 to facilitate wiring.

[0024] In use, the staff first takes out the fixing structure, so that the temperature controller temperature sensing probe is placed inside the temperature sensing head sleeve 7, and the temperature controller temperature sensing probe needs to be inserted a distance from the through hole 703 to ensure that the temperature controller temperature sensing probe can contact the bottom of the electric hot water bucket, and both temperature controller temperature sensing probes are completed inside the temperature sensing head sleeve 7. After that, the staff fixes the cover bottom cover 1 on the top wall of the electric hot water bucket in a bolted manner. At this time, a cavity region is formed between the cover bottom cover 1 and the top wall of the electric hot water bucket, and the temperature controller temperature sensing probe is located inside the temperature sensing head sleeve 7. Then, the staff can adjust the operation of the rotary self-locking drive mechanism 5 through an external control device, such as a knob or an electronic control panel, so that the rotary power of the rotary self-locking drive mechanism 5 is transmitted to the two reference shafts 3 through the gear transmission 4. The two reference shafts 3 rotate synchronously and reversely, and then the right-angle arm 6 rotates around the reference shaft 3 as the central axis to adjust the position of the temperature sensing head sleeve 7 and the temperature controller temperature sensing probe in the electric hot water bucket, so that the probe is always in the optimal temperature measurement position and can more accurately capture the average temperature of the water body. By flexibly adjusting the position of the temperature sensing probe, the risk of overheating or dry burning is effectively reduced.
