Description

Technical Field

[0001] This utility model relates to the field of heating equipment, and in particular to the design of a heating chamber with multiple independent working heating elements. Background Technology

[0002] In heating equipment, the heating chamber is the core heating component, which heats the circulating water or water to be heated through heating elements to achieve the function of heating or hot water supply.

[0003] Existing heating chambers generally use a single heating element design. To meet users' demand for "rapid heating," high-power heating elements (typically ≥2000W) are required. However, high-power heating elements generate significant vibration and thermal noise during operation, especially at night, severely impacting user comfort. While using a low-power single heating element to reduce noise can decrease noise levels, it significantly slows down the heating speed, failing to meet heating / hot water supply needs. Furthermore, maintaining the set temperature requires frequent on / off switching of a single high-power heating element (i.e., "start-stop" mode), easily leading to fluctuations in water and room temperature, affecting heating comfort. The frequent switching of high current also accelerates wear and tear on the heating element and its control components, reducing the reliability and lifespan of the entire heating system.

[0004] Therefore, it is necessary to optimize the existing heating chamber structure to achieve rapid and efficient heating while also ensuring low-noise operation, temperature stability, and long-term reliability. Summary of the Invention

[0005] The purpose of this invention is to provide a heating chamber with multiple independent working heating elements to solve the related problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a tank body and a heating cavity formed on the tank body. The tank body is provided with an inlet and an outlet. The heating cavity is provided with a set of independently operating heating elements. The heating elements include a main heating element and an auxiliary heating element. The tank body is also provided with a sealing and fixing assembly for fixing each heating element in the heating cavity. Each heating element is connected to a control module.

[0007] To ensure airtightness, the sealing and fixing assembly includes a first sealing plate adapted to the heating chamber opening, a second sealing plate abutting the first sealing plate, and a locking assembly that locks the chamber body, the first sealing plate, and the second sealing plate together. The first sealing plate is provided with a set of heating element through holes adapted to each heating element, and the second sealing plate is provided with a set of heating element clamping holes adapted to each heating element. A first elastic sealing ring is provided between the first sealing plate and the chamber body to prevent liquid from leaking out from the joint between the first sealing plate and the chamber body, and a second elastic sealing ring is provided between the first sealing plate and the second sealing plate to prevent liquid from leaking out from the joint between the heating element and the heating element through holes.

[0008] Furthermore, a sealing ring fixing groove is provided around the heating chamber opening on the chamber body, and the first elastic sealing ring is fixed in the sealing ring fixing groove; each of the second elastic sealing rings is respectively sleeved on each heating plate, and the heating plate has a chamfered corner at the end facing the second sealing plate through the hole.

[0009] Preferably, both the first elastic sealing ring and the second elastic sealing ring are made of high-temperature resistant silicone material.

[0010] To further ensure sealing, the locking assembly includes a set of first bolts for locking the first sealing plate onto the chamber body, and a set of second bolts for locking the second sealing plate onto the first sealing plate. The first sealing plate is provided with a first bolt hole adapted to the first bolt, the chamber body is provided with a first threaded hole adapted to the first bolt, the second sealing plate is provided with a second bolt hole adapted to the second bolt, the first sealing plate is provided with a second bolt clearance hole adapted to the second bolt, and the chamber body is provided with a second threaded hole adapted to the second bolt.

[0011] Preferably, at least one main heating element and one auxiliary heating element are provided, the power of the main heating element is 1800W, and the power of the auxiliary heating element is 1000W.

[0012] For ease of installation, a pressure switch mounting blind hole is provided on each side of the chamber, and a temperature switch fixing thread hole is provided on one side of the chamber.

[0013] To ensure the structural strength and thermal conductivity of the silo, the silo body is made of die-cast aluminum alloy.

[0014] The beneficial effects of this utility model are: 1. This utility model features an independent working combination design for the main heating element and auxiliary heating elements. During startup, multiple elements work collaboratively, resulting in high total power and meeting rapid heating requirements. It eliminates the need for a single high-power heating element, and the power of a single element is lower than that of traditional 2000W+ high-power heating elements, significantly reducing vibration and noise, making it particularly suitable for quiet nighttime use and improving living comfort. Once the set temperature is reached, only a single auxiliary heating element needs to operate at low power to maintain the temperature, avoiding frequent start-stop cycles from a single high-power heating element. This avoids temperature fluctuations caused by frequent start-stop cycles of a single heating element and reduces wear and tear on the heating elements and control components due to high current switching, extending the service life and operational reliability of the entire heating system.

[0015] 2. The sealing and fixing assembly uses the first sealing ring to block leakage at the joint between the chamber and the sealing plate, and the second sealing ring to fill the gap between the heating plate and the through hole with the chamfer. The sealing ring is made of high-temperature resistant silicone material, which effectively prevents liquid leakage in the heating chamber.

[0016] 3. The chamber body is made of die-cast aluminum alloy, balancing high thermal conductivity and structural strength to ensure the accuracy and lifespan of the temperature switch. It also features optional blind holes for installing the pressure switch to avoid installation interference. Furthermore, both pressure and temperature switches can be installed simultaneously for dual safety protection. Attached Figure Description

[0023] Examples, such as Figure 1-6As shown, a heating chamber with multiple independently operating heating elements includes a rectangular chamber body 1 and a heating cavity 2 disposed on the chamber body 1. The chamber body 1 is provided with a water inlet 3 and a water outlet 4. A set of independently operating heating elements 5 are disposed within the heating cavity 2. Each heating element 5 includes a main heating element 51 and an auxiliary heating element 52. The chamber body 1 is also provided with a sealing and fixing assembly 6 for fixing each heating element 5 within the heating cavity 2. Each heating element 5 is connected to a control module 10. At least one main heating element 51 and one auxiliary heating element 52 are provided. The power of the main heating element 51 is 1800W, and the power of the auxiliary heating element 52 is 1000W.

[0024] The working principle of this utility model is as follows: When the heating device is first started, the main heating element 51 and the auxiliary heating element 52 are controlled by the control module 10 to work together. At this time, the heating efficiency is the highest and the heating speed is the fastest. When the set temperature is reached, the control module 10 controls only one 1000W auxiliary heating element 52 to work to maintain the temperature.

[0025] To facilitate the fixing of the heating element 5, the sealing and fixing assembly 6 includes a first sealing plate 61 adapted to the opening of the heating chamber 2, a second sealing plate 62 abutting against the first sealing plate 61, and a locking assembly 9 that locks the chamber 1, the first sealing plate 61, and the second sealing plate 62 together. The first sealing plate 61 is provided with a set of heating element through holes 611 adapted to each heating element 5, and the second sealing plate 62 is provided with a set of heating element clamping holes 621 adapted to each heating element 5. The heating element 5 and the heating element clamping holes 621 are interference fit. During assembly, one end of the heating element 5 is clamped through the heating element clamping holes 621, and the other end passes through the heating element through holes 611 and extends into the heating chamber 2. Finally, the locking assembly 9 locks the first sealing plate 61, the second sealing plate 62, and the chamber 1 together.

[0026] To ensure airtightness, a first elastic sealing ring 7 is provided between the first sealing plate 61 and the chamber 1, and a set of second elastic sealing rings 8 is provided between the first sealing plate 61 and the second sealing plate 62 to prevent liquid from leaking out from the joint between the heating element 5 and the heating element through hole 611. A sealing ring fixing groove 11 is provided around the opening of the heating chamber 2 on the chamber body 1. The first elastic sealing ring 7 is fixed in the sealing ring fixing groove 11. When the locking component 9 is locked, the first elastic sealing ring 7 is compressed to form a seal, ensuring that the liquid in the heating chamber 2 will not leak out from the joint between the first sealing plate 61 and the chamber body 1. Each second elastic sealing ring 8 is respectively sleeved on each heating element 5. The heating element through hole 611 has a relief chamfer 612 at the end facing the second sealing plate 62. When the locking component 9 is locked, the second elastic sealing ring 8 is compressed and squeezed into the relief chamfer 612, thereby filling the relief chamfer 612 and ensuring that the liquid does not leak out from the joint between the heating element 5 and the heating element through hole 611. Preferably, both the first elastic sealing ring 7 and the second elastic sealing ring 8 are made of high-temperature resistant silicone material to ensure sealing stability.

[0027] The locking assembly 9 includes a set of first bolts 91 for locking the first sealing plate 61 onto the chamber 1. The first bolts 91 are tapered bolts. The second bolts 92 are used to lock the second sealing plate 62 onto the first sealing plate 61. The first sealing plate 61 is provided with a first bolt hole 613 that matches the first bolts 91. The first bolt hole 613 is also tapered to ensure that the first bolts 91 do not interfere with the second sealing plate 62 during assembly. The chamber 1 is provided with a first threaded hole 12 that matches the first bolts 91. The second sealing plate 62 is provided with a second bolt hole 622 that matches the second bolts 92. The first sealing plate 61 is provided with a second bolt clearance hole 614 that matches the second bolts 92. The chamber 1 is provided with a second threaded hole 13 that matches the second bolts 92. During assembly, the first sealing plate 61 is first locked onto the chamber 1 by the first bolt 91, then the heating element 5 is passed through the heating element through hole 611, and then the second sealing plate 62 is locked onto the first sealing plate 61 by the second bolt 92. The first bolt 91 and the second bolt 92 are locked together to ensure a firm lock and further ensure the sealing performance.

[0028] To ensure safety, each side of the chamber 1 has a pressure switch mounting blind hole 14 for fixing the pressure switch 20, and one side of the chamber 1 has a temperature switch fixing threaded hole 15 for fixing the temperature switch 30. This dual installation of the pressure switch 20 and temperature switch 30 provides enhanced safety and reliability. Both the pressure switch 20 and temperature switch 30 are also connected to the control module 10. During assembly, due to the relatively tall shape of the pressure switch 20, interference may occur depending on the location of the chamber 1 on the heating equipment, preventing its installation. Therefore, depending on the actual situation, one of the pressure switch mounting blind holes 14 can be opened to connect with the heating cavity 2, and threads can be tapped into the inner wall of this hole to fix the pressure switch 20 to the chamber 1 using threaded engagement. Since the temperature switch 30 detects temperature through conduction, the chamber 1 is made of die-cast aluminum alloy, which not only has good thermal conductivity but also excellent strength.
