Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, the position of an evaporator in the conventional fan heater in the air industry market is replaced by a PTC heater, but the quality of the PTC heater is far smaller than that of the evaporator, so that the stability of the fan heater is greatly reduced, and the fan heater is easy to fall down. In addition, the high center of gravity of the fan heater further increases the risk of the machine falling over the ground.
Meanwhile, the PTC heater generates heat obviously in the electrifying process, the surface temperature is very high, and the heater shakes or even falls off due to the falling or displacement of the machine, so that the risks of scalding personnel, electric shock and the like are easily caused.
The prior art mainly installs the parts of falling prevention on the electric fan heater, prevents the machine from falling to the ground from the structure, but the machine still has the possibility of falling to the ground in this scheme, namely still has the potential safety hazard.
Therefore, the invention provides a fan heater falling protection system. Fig. 1 is a schematic structural diagram of a fan heater falling-down protection system provided by the present invention, and as shown in fig. 1, the protection system includes a radar module 110 and a controller 120.
Wherein, radar module 110 is connected with the input of controller 120 to can send radar module 110's shut down signal to radar module 110, the output of controller 120 is connected with the actuating mechanism of electric fan heater, thereby controller 120 can control actuating mechanism stop work. The actuator may be a heater, a fan, etc. of a warm air blower, which is not limited in this embodiment of the present invention.
In addition, radar module 110 sets up in the base of electric fan heater to can real-time detection base and the distance between the ground, controller 120 can set up in the fuselage of electric fan heater, also can set up in the base of electric fan heater.
In the monitoring process of the radar module 110, if the distance between any point on the base and the ground is greater than a preset value, it indicates that the fan heater may fall over, or is about to fall over, or has displacement.
If the warm air blower falls down or shifts, the heater in the warm air blower may shake or even fall off to the surface, and at this time, if the heater is in a working state, the surface temperature of the heater is high, which easily causes a scald to a person, and in addition, if the heater contacts with inflammable substances (such as plastic parts and the like) after falling down, the plastic parts are ignited, which brings about a potential safety hazard.
Therefore, in the embodiment of the invention, the distance between the base and the ground is detected in real time through the radar module 110, if the distance between the base and the ground is greater than the preset value, the radar module 110 sends a stop signal to the controller 120, and after the controller 120 receives the stop signal, the controller 110 controls the execution mechanism (such as a heater) of the warm air blower to stop working, so that the problems of scalding of personnel, ignition of plastic parts and the like are avoided after the warm air blower falls down or shifts. The preset value may be specifically set according to an actual situation, and the embodiment of the present invention is not specifically limited to this.
It should be noted that, a bluetooth unit may be disposed on the radar module 110, and performs bluetooth communication with the controller 120; or may be electrically connected to the controller 120 and communicate with the controller 120 via wires; radar module 110 may also enable both bluetooth communication and line communication with controller 120.
As a preferred embodiment, the user may select the communication mode according to actual requirements, or may preferentially select the bluetooth communication mode, and not only may send the shutdown signal to the controller 120, but also may send the shutdown signal to a mobile terminal (e.g., a mobile phone) of the user, so that the user can know the state of the fan heater in time. Under the condition that bluetooth communication has a problem, switch into the line communication mode to can guarantee that controller 120 can in time acquire shutdown signal, and control actuating mechanism stop work, avoid causing personnel to scald scheduling problem.
Although the warm air blower can be prevented from falling to the ground by arranging the anti-falling part in the traditional method, the warm air blower still has the risk of falling to the ground, and if the warm air blower falls to the ground, the safety risk to personnel cannot be controlled. Therefore, the distance between the base and the ground is detected through the radar module, and if the distance is larger than the preset value, the executing mechanism is controlled to be powered off and stop working, so that the problems that a user is scalded and the like can be avoided after the fan heater falls down on the ground.
According to the warm air blower falling protection system provided by the embodiment of the invention, the distance between the base of the warm air blower and the ground is detected through the radar module, and if the distance is greater than a preset value, a stop signal is sent to the controller, so that the controller controls the execution mechanism to stop working, and the problem of potential safety hazard to personnel after the warm air blower falls to the ground can be avoided.
Based on the above embodiment, further include: at least one counterweight, the counterweight sets up in the base.
In particular, since the warm air blower employs the PTC heater instead of the evaporator, and the mass of the PTC heater is smaller than that of the evaporator, the bottom structure of the warm air blower is unstable and tends to fall down due to vibration and the like. In addition, the high gravity center of the fan heater is also one of the factors causing the risk of falling down.
Therefore, the counterweight is arranged on the base, so that the gravity center height of the warm air blower can be reduced, the stability of the bottom of the warm air blower is improved, and the warm air blower is prevented from falling on the ground. The weight member may be an iron block with a relatively high density, a stainless steel block, or the like, which is not particularly limited in this embodiment of the present invention.
Therefore, according to the warm air blower falling protection system provided by the embodiment of the invention, the base is provided with the weight piece, so that the center height of the warm air blower can be reduced, the stability of the warm air blower on the ground is ensured, and the warm air blower is prevented from falling to the ground.

Specifically, if the warm air blower protection system of falling to the ground includes a weight, then set up the weight in the center of base to can make the base keep balanced stable state, and then reduce the central height of warm air blower, guarantee the stability of warm air blower on ground, prevent that the warm air blower from falling to the ground.
Therefore, the counterweight is arranged in the center of the base, so that the weight of the base can be increased, the balance of the base can be ensured, and the fan heater can be further prevented from falling to the ground.
Based on any embodiment, if the warm air blower falling protection system comprises at least two weight members, the weight members are distributed along the central array of the base.
Specifically, if the warm air blower falling protection system comprises at least two weight members, the weight members are distributed along the central array of the base. For example, if the protection system comprises two weight members, the two weight members may be respectively disposed at both ends of a line segment passing through the center of the base; if the protection system comprises four accessories, a circle can be determined by taking the center of the base as the center of a circle and taking the preset length as the radius (the radius is smaller than the radius or the length of the base), and the four accessories are respectively arranged on four equal division points of the circle.
Therefore, the warm air blower falling protection system provided by the embodiment of the invention has the advantages that the balance of the warm air blower can be kept by increasing the weight of the base of the warm air blower by distributing the weight parts along the central array of the base, and the warm air blower is prevented from falling.
Based on any one of the above embodiments, the mass of the weight member is greater than a preset mass, which is determined based on the center of gravity of the fan heater.
Specifically, the larger the mass of the weight member is, the larger the mass added to the base of the fan heater is, so that the bottom of the fan heater is more stable. In addition, if the weight member has too large mass, although the stability of the bottom of the fan heater can be ensured, the cost of parts required to be consumed is higher.
Therefore, the preset quality is determined based on the center of the fan heater, so that the material cost of the counterweight part can be saved on the basis of ensuring the stability of the bottom of the fan heater, the fan heater can be prevented from falling to the ground, and the cost of a fan heater falling to the ground protection system can be reduced.
Based on any of the above embodiments, the radar module 110 further includes a start-up sub-module, and the start-up sub-module is configured to send a start-up signal to the controller 120 when the distance between the base and the ground is less than or equal to a preset value, so that the controller 120 controls the execution mechanism to start working.
Specifically, if the distance between the base and the ground is less than or equal to the preset value, it indicates that the fan heater is in a normal state (i.e., there is no risk of falling down), and therefore the radar module 110 sends a start-up signal to the controller 120, so that the controller 120 controls the execution mechanism to start working, and thus the fan heater can be guaranteed to start working in time when in a normal state.
Therefore, when the distance between the base and the ground is smaller than or equal to the preset value, the radar module sends a starting signal to the controller, and therefore the fan heater can start to work in time when the fan heater is recovered to a normal state.
Based on any one of the above embodiments, the warm air blower falling protection system further includes: the anti-falling component is arranged on the body of the warm air blower.
Specifically, in order to prevent the warm air blower from falling down, the anti-falling component is arranged on the body of the warm air blower, so that the warm air blower can be prevented from falling down, and the problems of scalding of personnel and the like are avoided. The anti-falling component may be an anti-falling bracket, an anti-falling fixer, etc., and the embodiment of the present invention is not particularly limited to this.
Therefore, according to the embodiment of the invention, the anti-falling component is arranged on the body of the warm air blower, and the working state of the executing mechanism is controlled by combining the radar module to detect the distance between the base and the ground, namely, the electric control logic is added to control the working state of the executing mechanism, so that the warm air blower can be prevented from falling on the ground, and the executing mechanism can be controlled to stop working after the warm air blower falls on the ground, so that the problems of scalding of personnel and the like are avoided.

Therefore, the embodiment of the invention alarms when the distance between the base and the ground is larger than the preset value by arranging the alarm module, so that the fan heater can remind nearby people of the falling risk, the people can evacuate timely, and the safety of the people is ensured.
Therefore, when the distance between the base and the ground is larger than the preset value, the alarm module gives an alarm, so that nearby people can evacuate timely, and the safety of the people is guaranteed.
The alarm may be an alarm in a sound form or an audible and visual alarm, which is not specifically limited in the embodiment of the present invention.
Based on any embodiment above, still include: and the communication module is connected with the radar module and used for sending a signal of falling to the ground to the background server when the distance between the base and the ground is greater than a preset value.
Specifically, when the distance between the base and the ground is larger than a preset value, the fact that the fan heater falls down or is about to fall down is indicated. If the fan heater falls down for a long time, other parts may be damaged, and maintenance cost is increased.
Therefore, when the distance between the base and the ground is larger than the preset value, the embodiment of the invention sends a falling signal to the background server through the communication module, so that related personnel can know the state of the fan heater in time and maintain the fan heater in time, and the problem that other parts are damaged due to falling for a long time is avoided.

Based on any one of the above embodiments, the present invention further provides a method for protecting a fan heater from falling over a floor, which is based on any one of the above embodiments, and as shown in fig. 2, the method includes:
and step 220, after the controller receives the stop signal, controlling the execution mechanism to stop working through the controller.
Specifically, the radar module is arranged on a base of the fan heater, the distance between the base and the ground can be detected in real time, and in the monitoring process of the radar module, if the distance between any point on the base and the ground is larger than a preset value, it is indicated that the fan heater possibly falls over at the moment, or is about to fall over, or shifts.
If the warm air blower falls down or shifts, the heater in the warm air blower may shake or even fall off to the surface, and at this time, if the heater is in a working state, the surface temperature of the heater is high, which easily causes a scald to a person, and in addition, if the heater contacts with inflammable substances (such as plastic parts and the like) after falling down, the plastic parts are ignited, which brings about a potential safety hazard.
Therefore, the distance between the base and the ground is detected in real time through the radar module, if the distance between the base and the ground is larger than the preset value, the radar module can send a stop signal to the controller, and after the controller receives the stop signal, the controller controls the execution mechanism (such as a heater) of the warm air blower to stop working, so that the problems that personnel scald and plastic parts are ignited after the warm air blower falls down or shifts are solved. The preset value may be specifically set according to an actual situation, and the embodiment of the present invention is not specifically limited to this.
It can be understood that after the controller controls the execution mechanism to stop working, if the radar module detects that the distance between the base and the ground is less than or equal to a preset value, it indicates that the state of the fan heater is recovered to be normal at the moment, and the radar module sends a starting signal to the controller so that the controller controls the execution mechanism to start working, and therefore the fan heater can start working in time after the normal state is recovered.
Although the warm air blower can be prevented from falling to the ground by arranging the anti-falling part in the traditional method, the warm air blower still has the risk of falling to the ground, and if the warm air blower falls to the ground, the safety risk to personnel cannot be controlled. Therefore, the distance between the base and the ground is detected through the radar module, and if the distance is larger than the preset value, the executing mechanism is controlled to be powered off and stop working, so that the problems that a user is scalded and the like can be avoided after the fan heater falls down on the ground.
