Description

Technical Field

[0001] The invention relates to the technical field of boilers, and in particular to a heating structure of a low-energy electromagnetic heating boiler. Background Art

[0002] A boiler is an energy conversion device that can convert various chemical energies into heat energy for external output. The boiler uses an insulation layer to insulate the hot water inside. The higher the temperature of the hot water in the boiler, the greater the temperature difference between it and the external environment. The greater the temperature difference, the faster the heat energy of the hot water in the boiler will dissipate, resulting in increased energy consumption. Although reducing the temperature difference can reduce energy consumption, the reduced temperature difference will cause the hot water in the boiler to not meet the temperature standard when it is needed, making it difficult to use immediately.

[0003] Electric heating boilers convert heat energy through electric current heating resistors. In order to ensure the hot water supply of the boiler, it is often necessary to continuously heat the boiler electrically, which consumes a lot of electricity. In order to reduce energy consumption, existing heating boilers are often insulated by temperature control devices. When the temperature is lower than a certain requirement, the heating device inside the boiler will be automatically turned on for heating. Although this method does not require power supply all the time, it consumes a lot of electricity. However, if the heating of the boiler is not guaranteed, the existing boiler heating structure will cause the inability to quickly provide hot water when hot water is needed to meet the use needs, affecting the use experience of the boiler. Based on this, a low-energy electromagnetic heating boiler heating structure is proposed. Summary of the invention

[0013] Preferably, the torsion shaft is arranged on the U-shaped connecting block, the end of the traction link support rod is provided with a sleeve opening adapted to the torsion shaft, and the torsion shaft is provided with a torsion return spring connected to the traction link support rod.

[0014] Preferably, the water outlet pipeline comprises a water delivery concentrator arranged in the water collecting seat, and the water delivery concentrator is respectively connected to a short-time hot water pipeline and a continuous hot water pipeline;

[0015] The water delivery central pipe is connected to a plurality of shunt pipes, a butt joint half pipe is fixedly connected to the bottom of the semi-heating inner sleeve, and the butt joint half pipe on the semi-heating inner sleeve located on the outside is connected to the shunt pipe.

[0016] Preferably, a linkage cavity is provided on the electromagnetic heating element, and the linkage cavity is provided with a plurality of fan-shaped openings for the resistance heating fan-shaped element to move.

[0017] Preferably, the resistance member includes a damping connecting member arranged in the linkage cavity, the damping connecting member is fixedly connected with a resistance column extending outward through the linkage cavity, the damping connecting member is connected to the inner wall of the linkage cavity through a resistance spring sleeved on the outer wall of the resistance column, and the damping connecting member is connected to the resistance heating fan-shaped member through a linkage resistance rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention designs different heating methods according to different requirements when using electric heating boilers. The user's usage requirements are obtained by flow sensors arranged on the short-time hot water pipeline and the continuous hot water pipeline. The two semi-heating components are connected through a centralized heating device. The liquid flowing in through the semi-outer sleeve, the semi-center guide cover and the semi-heating inner sleeve is centrally heated by two groups of electromagnetic heating elements.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example, see Figures 1 to 6A low-energy electromagnetic heating boiler heating structure comprises a heating furnace body and a control end seat 1 provided with a master control module, the heating furnace body is arranged above the control end seat 1, and a water outlet pipeline connected to the heating furnace body is arranged in the control end seat 1;

[0034] Furthermore, the water outlet pipeline includes a water delivery concentrator 15 disposed in the water collecting seat 2, and the water delivery concentrator 15 is respectively connected to a short-time hot water pipeline 16 and a continuous hot water pipeline 17;

[0035] It is worth noting that when the short-time hot water pipeline 16 is in use, it is in a centralized heating mode when it is powered, and when the continuous hot water pipeline 17 is in a continuous heating mode, it can meet the use under different conditions.

[0036] Flow sensors are provided on both the short-time hot water pipeline 16 and the continuous hot water pipeline 17 to transmit the detected data to the control terminal seat 1. The master control module provided in the control terminal seat 1 will obtain the data and then select different heating modes for heating.

[0037] The water supply central pipe 15 is connected to multiple branch pipes 18, and a docking half pipe 19 is fixedly connected to the bottom of the semi-heating inner sleeve 8, wherein the docking half pipe 19 is trumpet-shaped, which can reduce the conveying flow rate, and the docking half pipe 19 on the outer semi-heating inner sleeve 8 is connected to the branch pipe 18.

[0038] It is worth noting that the water supply central pipe 15 and the diversion pipe 18 are both arranged inside the water collecting seat 2. When the half pipe 19 is docked, the effect of centralized hot water supply can be achieved, thereby ensuring that in the process of external water supply, the hot water is heated by the centralized heating device and then flows out.

[0039] The heating furnace body is composed of a water collecting seat 2 installed above the control end seat 1 and a heat preservation furnace 3 connected to the water collecting seat 2. A water inlet column 4 is arranged at the center of the heat preservation furnace 3. The water inlet column 4 is externally connected to a water inlet pipe. Water flows out from the opening inside the water inlet column 4. The water inlet column 4 is connected to a magnetic linkage disk 5 through an electromagnetic control component.

[0040] Furthermore, the electromagnetic control component includes an electromagnetic disk 11 fixedly arranged at the center of the water inlet column 4. There are two magnetic linkage disks 5, which are respectively arranged on both sides of the electromagnetic disk 11 and are magnetically attracted to the electromagnetic disk 11. In the process of supplying power to the electromagnetic disk 11, the electromagnetic disk 11 is electrically generated magnetism, which will cause the magnetic linkage disks 5 originally on both sides to move closer to the middle, thereby achieving the effect of bringing the semi-heating components close to each other for centralized heating.

[0041] The magnetic linkage disk 5 is connected to a centralized heating device through a connecting rod assembly, and the connecting rod assembly includes a U-shaped connecting block 12 fixedly connected to the side wall of the inner semi-outer sleeve 6. The outer side wall of the magnetic linkage disk 5 is rotatably connected to a traction connecting rod support rod 13, and the other end of the traction connecting rod support rod 13 is connected to the U-shaped connecting block 12 through a torsion shaft 14.

[0042] Furthermore, the torsion shaft 14 is arranged on the U-shaped connecting block 12 , and a sleeve opening adapted to the torsion shaft 14 is provided at the end of the traction link support rod 13 , and the torsion shaft 14 is provided with a torsion return spring connected to the traction link support rod 13 .

[0043] A further advantage of adopting the above method is that, in the process of powering the electromagnetic disk 11, the magnetic linkage disks 5 originally on both sides will be brought closer together. In this process, the semi-heating assembly connected to it through the traction link support rod 13 and the U-shaped connecting block 12 will be driven to move outward, so as to close with the semi-heating assembly arranged in the groove of the insulation furnace 3. When the electromagnetic disk 11 loses power, the traction link support rod 13 will drive the magnetic linkage disk 5 to move away under the action of the torsion reset spring, so as to achieve the reset effect.

[0044] The centralized heating device comprises two sets of semi-heating components arranged opposite to each other, the semi-heating components located on the inner side are connected to the connecting rod components to achieve horizontal movement, and the semi-heating components located on the outer side are located in a groove provided in the heat preservation furnace 3, and the semi-heating components are composed of a semi-outer sleeve 6, a semi-central guide cover 7, a semi-heating inner sleeve 8 and an electromagnetic heating element 9 arranged in the semi-heating inner sleeve 8;

[0045] Furthermore, the half outer sleeve 6, the half middle guide cover 7 and the half heating inner sleeve 8 are arranged in sequence from the outside to the inside, and are connected to each other through a fixing block;

[0046] Among them, by arranging the semi-outer sleeve 6, the semi-central guide cover 7 and the semi-heating inner sleeve 8, the hot water entering the internal electromagnetic heating element 9 flows through the space between the outer semi-outer sleeve 6 and the semi-central guide cover 7 first, and then passes through the space between the semi-central guide cover 7 and the semi-heating inner sleeve 8, and finally enters the innermost semi-heating inner sleeve 8. In this process, it can be ensured that the flowing hot water in the heated state does not have the possibility of overflowing into the insulation furnace 3, and the multiple settings concentrate the heat in the innermost semi-heating inner sleeve 8, and the surrounding heated water will be preheated, and the preheated water will flow into the innermost water inlet column 4, thereby ensuring the high utilization of thermal energy.

[0047] A plurality of retractable resistance heating fan-shaped members 10 are evenly arranged on the electromagnetic heating member 9, and mutually offset abutment members are arranged between the electromagnetic heating members 9 that are arranged opposite to each other.

[0048] It should be noted that an electromagnetic coil is arranged inside the electromagnetic heating element 9, and a resistance heating fan-shaped element 10 is arranged at the coil spacing. A resistive heating material is arranged outside the resistance heating fan-shaped element 10, and the interior is an electromagnetic heating metal material. During the insulation stage, electric energy is converted into high-frequency alternating current, and an alternating magnetic field is generated through the electromagnetic coil. In the magnetic field, an induced current, i.e., eddy current, is generated in the resistance heating fan-shaped element 10. These eddy currents generate heat in the conductor, and their function is achieved by heating the heated object. When centralized heating is required, the effect of rapid centralized heating can be achieved through electromagnetic heating and resistance heating.

[0049] Scale is formed when salts such as calcium and magnesium contained in boiler feed water precipitate and adhere to the metal surface after being heated. The thermal conductivity of scale is very small. Scale forms on the heating surface of the boiler, which will greatly deteriorate the heat transfer effect and affect the efficiency of the boiler. It should be noted that the resistance heating fan-shaped element 10 can effectively scrape off the scale generated during the heating process during the expansion and contraction process in the electromagnetic heating element 9, and can ensure that the electromagnetic heating element 9 will not be covered with scale when in use, thereby ensuring the effective use of electrical energy and the heating efficiency of hot water.

[0050] Further, the resistance member includes a damping connector 20 arranged in the linkage cavity, the damping connector 20 is fixedly connected with a resistance column 21 extending outward through the linkage cavity, the damping connector 20 is connected to the inner wall of the linkage cavity through a resistance spring sleeved on the outer wall of the resistance column 21, the damping connector 20 is connected to the resistance heating sector 10 through a linkage resistance rod 22, both ends of the linkage resistance rod 22 are connected to the resistance heating sector 10 through the shaft and the hole to achieve the effect of rotational docking, the electromagnetic heating element 9 is provided with a linkage cavity, and the linkage cavity is provided with a plurality of sector openings for the resistance heating sector 10 to move;

[0051] It is worth noting that when the electromagnetic heating elements 9 approach each other, the offset resistance columns 21 thereon will squeeze each other, causing the resistance columns 21 to move into the linkage cavity. The inward movement of the resistance columns 21 will drive the damping connection 20 to move, thereby causing the resistance heating fan-shaped element 10 connected by the linkage resistance rod 22 to move outward, thereby achieving the effect of outward expansion of the resistance heating fan-shaped element 10, increasing the contact surface with the water flow, increasing the heating area, and improving the heating effect.

[0052] The boiler heating structure proposed in the present invention can be divided into a centralized heating mode and a continuous heating mode according to the use requirements of short-term hot water supply and continuous hot water supply. The specific process includes the following:

[0053] When the short-time hot water pipe 16 is discharging water, the flow sensor arranged thereon will obtain a signal. At this time, the master control module will supply power to the electromagnetic disk 11. The electromagnetic disk 11 will generate magnetic force when it is supplied with power, so that the two magnetic linkage disks 5 arranged on the water inlet column 4 will move closer to the middle. In the process of approaching, the semi-heating component originally in the middle and capable of horizontal movement will be moved to the outside, and finally, the semi-outer sleeve 6, the semi-central guide cover 7 and the semi-heating inner sleeve 8 will be connected in pairs.

[0054] After docking, the electromagnetic heating elements 9 arranged in the semi-heating inner sleeve 8 will conflict with each other, so that the resistance heating fan-shaped elements 10 originally contained in the electromagnetic heating elements 9 will move outward under the action of the conflicting pillars 21. The resistance heating fan-shaped elements 10 moved out will decelerate the water flowing therethrough, and at the same time increase the contact area, improve the heat exchange effect of the water flow, ensure effective heating of the water flowing through the semi-heating inner sleeve 8, ensure rapid heating of the water flow, and the hot water supplied can meet the temperature requirements. Compared with heating the water in the entire insulation furnace 3, it can significantly reduce the consumption of electric energy, shorten the heating time, realize centralized heating, and reduce heat loss, that is, ensure short-term hot water supply, and avoid electric energy loss.

[0055] When the continuous hot water pipeline 17 is discharging water, the flow sensor arranged thereon will obtain a signal. At this time, the master control module will first turn on the electromagnetic disk 11 and delay the power supply. During the power supply process, the outflowing water flow can be centrally heated by combining the semi-heating components. During the centralized heating process, the temperature will be gradually absorbed by the water flow in the heating furnace body. At this time, the magnetic force of the electromagnetic disk 11 can be weakened, so that the two electromagnetic heating elements 9 that were originally concentrated for heating can be gradually dispersed to both sides. In the process of gradual dispersion, the heating area in the insulation furnace 3 will be gradually increased, and finally the water flow in the entire furnace body can be heated, so as to meet the demand for continuous water discharge. In the process of ensuring the rapid provision of hot water, the water flow in the furnace body can be gradually heated, and the centralized utilization of heat can be realized. The water supply demand can be met without insulation, thereby ensuring the normal use of the boiler.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
