Technical Field
[0001] This utility model relates to the field of electric boiler technology, and in particular to an electric boiler that can be used for both heating and bathing. Background Technology
[0002] Electric boilers, also known as electric heating boilers or electric thermal boilers, are, as the name suggests, boiler equipment that uses electricity as its energy source and converts it into heat energy. This heat energy is then converted by the boiler and outputted as steam, high-temperature water, or organic heat carriers. As a new type of heating and hot water supply equipment, electric boilers have many advantages. They do not require fuel combustion, produce no pollutants, and are environmentally friendly. Furthermore, electric boilers operate relatively quietly, unlike gas boilers which produce combustion noise. In addition, electric boilers are easier to install, requiring no complex gas pipeline installation; simply connecting to a power source and water supply is sufficient for operation.
[0003] In existing electric boilers that can be used for both heating and bathing, the water around the heating element absorbs heat and its temperature rises first during use. However, due to the lack of a stirring mechanism, hot and cold water cannot mix fully, resulting in a significant temperature gradient inside the boiler. In some areas, the water temperature is too high, while in other areas the water temperature is too low, which hinders the uniform distribution of heat throughout the water body. Therefore, we have introduced a new electric boiler that can be used for both heating and bathing. Utility Model Content
[0004] The main purpose of this utility model is to provide an electric boiler that can be used for both heating and bathing, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A dual-purpose electric boiler for heating and bathing includes a boiler body. An L-shaped mounting plate is fixedly connected to the upper right side of the boiler body. An agitator is fixedly installed on the upper end of the L-shaped mounting plate. A water inlet pipe is fixedly connected to the upper rear side of the boiler body. A water level mechanism is inserted and connected to the upper left side of the boiler body. A water outlet pipe is fixedly connected to the lower left side of the outer surface of the boiler body. An air outlet pipe is fixedly connected to the upper right side of the outer surface of the boiler body. Four feet are fixedly connected to the lower outer side of the boiler body. A control panel is provided on the upper front center of the outer surface of the boiler body.
[0007] Preferably, the agitation mechanism includes a motor, a rotating rod is fixedly installed at the output end of the motor, a driving gear is fixedly connected to the lower end of the rotating rod, a driven gear is meshed with the outer surface of the driving gear, a rotating column is fixedly connected to the lower end of the driven gear, two connecting rods are fixedly connected to the left and right parts of the outer surface of the rotating column, and agitation plates are fixedly connected to the ends of the two connecting rods in the vertical direction away from the rotating column, and several through slots are opened at the front ends of the two agitation plates.
[0008] Preferably, the motor is fixedly mounted on the upper end of the L-shaped mounting plate, the rotating rod is inserted and connected to the L-shaped mounting plate, and the drive gear does not contact the L-shaped mounting plate.
[0009] By adopting the above technical solution, the motor is mounted on the upper part of the L-shaped mounting plate, which facilitates the maintenance of the motor.
[0010] Preferably, both agitator plates are located inside the electric boiler body, and the plurality of through slots are distributed at equal intervals.
[0011] By adopting the above technical solution, the stirring plate agitates the water inside the electric boiler body, which increases the water's fluidity inside the electric boiler body, allows the water to fully contact the heating elements of the electric boiler, accelerates the heat transfer process, and makes the heat evenly distributed in the water, avoiding local water temperatures that are too high or too low.
[0012] Preferably, the water level mechanism includes an L-shaped connecting bar and a movable rod. An alarm and a touch sensor are fixedly installed on the upper end of the L-shaped connecting bar, a contact bar is fixedly connected to the upper end of the movable rod, and a float is fixedly connected to the lower end of the movable rod.
[0013] Preferably, the inner right wall of the L-shaped connecting strip is fixedly connected to the electric boiler body, and the alarm is located to the left of the touch sensor.
[0014] By adopting the above technical solution, when the touch sensor comes into contact with the contact strip, an alarm can be triggered, allowing the operator to know immediately that the water level in the electric boiler has dropped to a dangerous level, so that measures can be taken in time to replenish the water source.
[0015] Preferably, the movable rod is movably connected to the electric boiler body, the float is located inside the electric boiler body, and the contact strip corresponds to the vertical position of the touch sensor.
[0016] By adopting the above technical solution, the float will descend with the liquid surface to determine the changes in water level.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. By setting up an agitation mechanism and starting the motor, the motor drives the drive gear to rotate via a rotating rod. The drive gear drives the driven gear that meshes with it, thereby causing the rotating column to drive two agitator plates to agitate the water inside the electric boiler body. This increases the water's fluidity inside the electric boiler body, allowing the water to fully contact the heating elements of the electric boiler, accelerating the heat transfer process, and ensuring that the heat is evenly distributed in the water. This avoids localized excessively high or low water temperatures, thereby improving heating efficiency. The agitator plates are equipped with through grooves, which allow the water to flow through during agitation, reducing the contact area between the agitator plates and the water, thus reducing the resistance during agitation. This helps to reduce the load on the motor and reduce energy consumption. In addition to increasing the fluidity of the water, the agitation process also accelerates the airflow inside the electric boiler, allowing hot air to enter the heating pipes from the air outlet pipe more quickly for heating, thereby improving heating efficiency.
[0019] 2. By setting a water level mechanism, when the water level inside the electric boiler drops, the float ball will drop with the liquid level. When the contact strip touches the touch sensor, the alarm will sound, allowing the operator to know immediately that the water level inside the electric boiler has dropped to a dangerous level, so that measures can be taken in time to replenish the water source, prevent the electric boiler from burning dry due to low water level, and avoid equipment damage or even safety accidents. It can also make the entire heating system more stable, reduce the number of unexpected shutdowns caused by water level problems, and ensure the continuity and stability of heating.

[0028] Please see Figure 1-4 This utility model provides a technical solution:
[0029] A dual-purpose electric boiler for heating and bathing includes a boiler body 1. An L-shaped mounting plate 2 is fixedly connected to the upper right side of the boiler body 1. An agitator 3 is fixedly installed on the upper end of the L-shaped mounting plate 2. A water inlet pipe 4 is fixedly connected to the upper rear side of the boiler body 1. A water level mechanism 5 is inserted and connected to the upper left side of the boiler body 1. A water outlet pipe 6 is fixedly connected to the lower left side of the outer surface of the boiler body 1. An air outlet pipe 7 is fixedly connected to the upper right side of the outer surface of the boiler body 1. Four foot supports 8 are fixedly connected to the lower outer side of the boiler body 1. A control panel 9 is provided on the upper front center of the outer surface of the boiler body 1.
[0030] In this embodiment, the stirring mechanism 3 includes a motor 31. A rotating rod 32 is fixedly installed at the output end of the motor 31. A driving gear 33 is fixedly connected to the lower end of the rotating rod 32. A driven gear 34 is meshed with the outer surface of the driving gear 33. A rotating column 35 is fixedly connected to the lower end of the driven gear 34. Two connecting rods 36 are fixedly connected to the left and right sides of the outer surface of the rotating column 35. A stirring plate 37 is fixedly connected to the ends of the two vertical connecting rods 36 away from the rotating column 35. Several through slots 38 are opened at the front ends of the two stirring plates 37. The motor 31 is fixedly installed on the upper end of the L-shaped mounting plate 2. The rotating rod 32 is inserted into the L-shaped mounting plate 2. The driving gear 33 does not contact the L-shaped mounting plate 2. The two stirring plates 37 are located inside the electric boiler body 1. The several through slots 38 are distributed at equal distances.
[0031] The above scheme involves starting the motor 31, which drives the drive gear 33 to rotate via the rotating rod 32. The drive gear 33 then drives the driven gear 34, which meshes with it, to rotate. This causes the rotating column 35 to carry the two agitator plates 37 to agitate the water inside the electric boiler body 1, increasing the water's flow within the boiler body 1. The agitator plates 37 are provided with through grooves 38, allowing water to flow through them during agitation, thus reducing the contact area between the agitator plates 37 and the water, and consequently reducing the resistance during agitation.
[0032] In this embodiment, the water level mechanism 5 includes an L-shaped connecting bar 51 and a movable rod 52. An alarm 53 and a touch sensor 54 are fixedly installed on the upper end of the L-shaped connecting bar 51. A contact bar 55 is fixedly connected to the upper end of the movable rod 52, and a float ball 56 is fixedly connected to the lower end of the movable rod 52. The inner right wall of the L-shaped connecting bar 51 is fixedly connected to the electric boiler body 1. The alarm 53 is located to the left of the touch sensor 54. The movable rod 52 is interlocked and movably connected to the electric boiler body 1. The float ball 56 is located inside the electric boiler body 1. The vertical position of the contact bar 55 corresponds to that of the touch sensor 54.
[0033] With the above scheme: when the water level inside the electric boiler body 1 drops, the float ball 56 will drop with the liquid level. When the contact strip 55 touches the touch sensor 54, the alarm 53 will sound an alarm, so that the operator can know immediately that the water level inside the electric boiler body 1 has dropped to a dangerous level, so as to take timely measures to replenish the water source and prevent the electric boiler body 1 from dry burning due to the low water level.
[0034] It should be noted that this utility model is a dual-purpose electric boiler for heating and bathing. During use, an external water pipe is connected to the inlet pipe 4, and the outlet pipe 6 is connected to the bathing system piping. The steam outlet pipe 7 is connected to the heating system piping. Water can be injected into the electric boiler body 1 through the inlet pipe 4. Then, the heating function of the electric boiler body 1 is activated, and the motor 31 is started simultaneously. The motor 31 drives the rotating rod 32 to rotate, which in turn drives the drive gear 33 to rotate. The drive gear 33 then drives the driven gear 34, which meshes with it, to rotate. This causes the rotating column 35 to drive two agitator plates 37 to agitate the water inside the electric boiler body 1, enhancing water flow. The agitator plates 37 are designed with through grooves 38, allowing water to flow through them during agitation, reducing the contact area between the agitator plates 37 and the water, thereby reducing resistance during agitation. This helps reduce the load on the motor 31 and save energy. In addition, the agitation of the water not only improves the fluidity of the water but also accelerates the airflow inside the electric boiler body 1, allowing hot air to enter the heating pipe more quickly through the air outlet 7, thus improving heating efficiency. When the water level in the electric boiler body 1 drops, the float ball 56 will drop along with the liquid level. Once the contact strip 55 touches the touch sensor 54, the alarm 53 will immediately sound an alarm. In this way, the operator can quickly know that the water level in the electric boiler body 1 has dropped to a dangerous level, so as to take timely measures to replenish the water source and prevent the electric boiler body 1 from burning dry due to low water level, avoiding equipment damage or even safety accidents. At the same time, it also makes the entire heating system more stable and reliable, reduces the number of unexpected shutdowns caused by water level problems, and ensures the continuity and stability of heating.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
