Referring to FIGS. 1 to 9, this embodiment provides a heater for a pool, which comprises a topple sensor 1, a heating assembly 2, a body 3 and a controller for driving the heating assembly 2 to heat or stop heating. The body 3 is provided with a water inlet 31 and a water outlet 32, and the heating assembly 2 is arranged in the body 3 for convection heating of water flowing through the body 3;
The topple sensor 1 comprises a moving member 11, a fixing member 12 and a sensor 13. The fixing member 12 has a chamber for accommodating the moving member 11, and the chamber has a taper; the sensor 13 is used to sense whether the relative position of the moving member 11 and the fixing member 12 have changed; when the fixing member 12 topples over, the moving member 11 moves relative to the fixing member 12, and the sensor 13 outputs a topple signal to the controller, so that the controller drives the heating assembly 2 to stop heating.
The heater for the pool outputs the topple signal through the change of the position of the topple sensor 1 when the body 3 topples over or not, and then controls the heater to stop heating after the body 3 is topple.
In order to achieve the above anti toppling effect, the moving member 11 is a magnet assembly, and the sensor 13 is a magnetic sensor and is arranged at the bottom of the chamber corresponding to the fixing member 12; when the fixing member 12 does not topple over, the moving member 11 contacts the bottom of the chamber of the fixing member 12, and the magnetic sensor receives a first magnetic field strength signal; when the fixing member 12 topples over, the moving member 11 is separated from the bottom of the chamber of the fixing member 12, and the magnetic sensor receives a second magnetic field strength signal; the strength of the first magnetic field strength signal is greater than the second magnetic field strength signal.
More specifically, the magnet assembly comprises a magnet fixing base 111 and a magnet 112; the magnet 112 is arranged at the bottom of the magnet fixing base 111. The magnet fixing base 111 is in the shape of a cone.
This embodiment further comprises an anti dry heating assembly 4, which is connected to the controller; when the water level in the body 3 is lower than a set threshold value, the anti dry heating assembly 4 outputs an anti dry heating signal to the controller, so that the controller drives the heating assembly 2 to stop heating.
Specifically, the anti dry heating assembly 4 is a float switch; when the water level is lower than a set threshold value, the float switch is disconnected.
In addition, during the use of the heater, it is better to keep the water temperature stable within a set threshold value, so that users will not have a bad experience because of the sudden cold and hot. Therefore, it further comprises a temperature sensor 5, which is connected to the controller; the temperature sensor 5 is used to detect the temperature in the body 3. When the temperature exceeds a set threshold value, the temperature sensor 5 outputs a temperature limiting signal to the controller so that the controller drives the heating assembly 2 to stop heating. Similarly, when the temperature is lower than a set threshold value, the temperature sensor 5 outputs a temperature limiting signal to the controller so that the controller drives the heating assembly 2 to start heating. In this way, the water temperature can be maintained within a range. In this embodiment, the heating assembly 2 and the temperature sensor 5 are fixed on the same metal support 21, so that the temperature sensor 5 can sense the water temperature more quickly and accurately during normal operation, and can collect more heat in the air in a larger area during dry heating, so as to achieve quick tripping response.
When the heating assembly 2 works, the hot air moves upward. Therefore, the temperature sensor 5 is set above the heating assembly 2 along the height direction of the body 3 to detect the temperature change more accurately and timely.
In addition, the outer side of the heating assembly 2 is provided with an anti-corrosion metal block 20.
The anti-corrosion metal block 20 is conductive to the heated liquid, and the chemical property of the anti-corrosion metal block 20 is more active than that of the heating assembly 2. The heating assembly 2 can be protected from corrosion by sacrificing the anti-corrosion metal block 20, and the anti-corrosion metal block 20 can be replaced regularly. The anti-corrosion metal block 20 can be made of zinc alloy, magnesium alloy, aluminum alloy, etc.
The water inlet 31 is arranged at the lower end of the body 3 along the height direction, and the water outlet 32 is arranged at the upper end of the body 3 along the height direction. This is good for exhaust.
Moreover, in this embodiment, in order to avoid the problem of water leakage inside the heater caused by the pulling of the power wire 6 of the heater, the power line 6 is first clamped by the wire clip. The wire clip is made of hard material, which plays a fixing role and does not participate in the sealing. Therefore, the sealing structure will not be affected during the pulling of the power line 6, and the leakage will not be caused by insufficient interference due to excessive deformation of the wire clip.
The sealing structure is realized through a sealing ring 7 and a fixing cover plate 8, so the number of parts involved in the sealing is relatively small, the cumulative tolerance is lower, and the production tolerance is improved.
Referring to FIG. 9, this embodiment further provides a pool with heating function, which comprises a pool body 9, a water pump 10 and the heater as described above; the water pump 10 is connected between the water outlet of the pool body 9 and the water inlet of the heater, and the water outlet of the heater is connected to the water inlet of the pool body 9.
It will be apparent to those skilled in the art that various modifications and variation can be made in the present disclosure without departing from the spirit or scope of the disclosure. Thus, it is intended that the present disclosure cover the modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents.
