Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The following disclosure provides many different embodiments, or examples, for implementing different features of the utility model. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Some air conditioners in the related art are provided with an electric heating device PTC (Positive Temperature Coefficient thermistor), the connection mode of the PTC is a connector lug led out from a PTC end and is connected with a wire end of an electric control device, an insulating part and a thermal shrinkage sleeve are sequentially sleeved at the connection part of the connector lug and the wire end outside the PTC end, but the PTC end is not completely wrapped, namely the front end of the PTC end is exposed outside and has no fireproof measure, at the moment, peripheral objects close to the PTC end inside the air conditioner need to be additionally provided with fireproof metal plates or the peripheral objects need to be made of fireproof materials in 5VA grade, so that fire prevention is guaranteed. If the PTC tip burns, a significant amount of smoke is carried over, causing a user to be panic and presenting a certain risk.

In short, the PTC of the related art does not have a fire-proof function, when the PTC is used in an air conditioner, fire-proof measures are required to be added around the terminal of the PTC, which increases the design difficulty and cost of the whole air conditioner, and if the terminal of the PTC is on fire, a large amount of smoke is generated, causing panic and certain danger. In order to solve at least one of the above technical problems, the present invention provides an electric heating assembly.

An electric heating assembly 100 according to an embodiment of the first aspect of the present invention will now be described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the electric heating assembly 100 includes a heating body 1, a first end 11 and a second end 12 are respectively arranged at two ends of the length of the heating body 1, and the electric heating body 1 includes a connection terminal 13 led out from the first end 11. The heating body 1 may be PCT (i.e., a Positive Temperature Coefficient thermistor, abbreviated as Positive Temperature Coefficient thermistor). The heating body 1 may include at least two terminals 13, such as a positive terminal and a negative terminal, and at least one terminal 13 is led out from the first end 11, that is, the first end 11 may be led out one or more terminals 13, for example, in a specific example, all the terminals 13 are led out from the first end 11, and for example, in other specific examples, the first end 11 is led out at least one terminal 13, and the second end 12 is also led out at least one terminal 13.

As shown in fig. 3-5, the electric heating assembly 100 further includes a mounting bracket 2 and a fireproof cover 3, the mounting bracket 2 is covered on the first end 11, and the mounting bracket 2 has a threading hole 21 for avoiding the connection terminal 13, so that the connection terminal 13 led out from the first end 11 can pass through the threading hole 21 to the outside of the mounting bracket 2. The fire-proof cover 3 covers the mounting bracket 2, a wire passing channel 101 is formed between the fire-proof cover 3 and the mounting bracket 2, a wire outlet 31 communicated with the wire passing channel 101 is formed on the fire-proof cover 3 or between the fire-proof cover 3 and the mounting bracket 2, and the power line 5 connected with the wiring terminal 13 is suitable for being wired through the wire passing channel 101 and penetrates out of the fire-proof cover 3 through the wire outlet 31.

From this, when binding post 13 is in contact failure with power cord 5, or binding post 13 self quality is bad, when leading to whole generating heat to reach the ignition, fire prevention cover 3 can seal flame inside fire prevention cover 3, because the space between fire prevention cover 3 and installing support 2, the clearance is less relatively (for example fire prevention cover 3 can clearance fit with installing support 2), be equivalent to comparatively inclosed cavity, flame burning will extinguish because of lacking oxygen in the very short time naturally (compare at least in not setting up fire prevention cover 3, can extinguish because of the oxygen deficiency sooner), thereby reach fine putting out a fire, fire prevention effect. It is understood that the fire-proof cover 3 described herein is made of fire-proof material, for example, 5VA fire-proof material, so as to have fire-proof effect.

It should be noted that, after reading the technical solutions of the present invention, it can be obviously understood that, when the second end 12 also leads out the terminal 13, for example, when the second end 12 also leads out the terminal 13, the second end 12 may also be provided with the mounting bracket 2 and the fireproof cover 3, so as to achieve the fireproof effect, that is, when the first end 11 and the second end 12 respectively lead out the terminal 13, in addition to the mounting bracket 2 and the fireproof cover 3 provided at the first end 11, the mounting bracket 2 and the fireproof cover 3 may also be correspondingly provided at the second end 12, so as to enable both ends of the heating body 1 to have the fireproof function.

For simplicity of description, only specific embodiments of the mounting bracket 2 and the fire-proof cover 3 mounted on the first end 11 will be described, and it is obvious to those skilled in the art that the specific embodiments of the mounting bracket 2 and the fire-proof cover 3 mounted on the second end 12 can be understood after reading the technical solution of the present invention. Of course, the utility model is not limited thereto, and all the terminals 13 of the heating body 1 may be led out from the first end 11, and in this case, the second end 12 may be provided with the mounting base 4 to facilitate the mounting of the electric heating assembly 100, as shown in fig. 2 and 6, for example.

In summary, according to the electric heating assembly 100 of the embodiment of the present invention, the fireproof cover 3 is covered outside the mounting bracket 2, and the gap space between the mounting bracket 2 and the fireproof cover 3 is utilized to achieve effective fire extinguishing and preventing effects, so that the electric heating assembly 100 of the embodiment of the present invention has a fireproof function, and peripheral objects thereof do not need to be provided with fireproof measures or adopt fireproof materials, thereby reducing the overall cost. Moreover, as the electric heating component 100 does not have fire protection requirements on peripheral objects any more, the design constraint of the peripheral objects is reduced, the overall design quality is improved, and the design difficulty of the whole machine is reduced. In addition, because the electric heating component 100 has a good fireproof function, the fire can be quickly extinguished, so that a large amount of smoke is not generated, panic is not caused to a user, and danger can be reduced.

When the electric heating equipment provided by the embodiment of the utility model is applied to household equipment, such as an air conditioner and the like, the electric heating equipment has better fireproof performance, so that objects around the wiring terminal 13 of the heating body 1 do not need to be added with fireproof measures, the whole machine can achieve a good fireproof effect, the design difficulty and the cost of the whole machine are reduced, the problem that a large amount of smoke is caused by burning of the wiring terminal 13 due to fire is solved, and the reliability and the use safety of the household equipment are improved.

In some embodiments of the present invention, as shown in fig. 3 to 5, the fireproof cover 3 includes a surrounding wall 32 disposed around the circumferential side surface of the first end 11, the wiring passage 101 is formed between the surrounding wall 32 and the mounting bracket 2, and the surrounding wall 32 is in clearance fit or sealing fit with the mounting bracket 2 at a position where the wiring passage 101 is not formed. Therefore, by stopping the relation between the surrounding wall 32 of the fireproof cover 3 and the mounting bracket 2 as described above, the wiring requirement can be met at the position of the wire passing channel 101, the relatively closed fireproof requirement can be met at the position where the wire passing channel 101 is not formed, and when the wiring terminal 13 is on fire, flame combustion can be naturally extinguished due to the lack of oxygen between the surrounding wall 32 and the mounting bracket 2 in a short time, so that good fire extinguishing and fireproof effects are achieved.

In short, by arranging the surrounding wall 32 of the fire-proof cover 3 to pass only the power line 5 and to have the rest in sealing fit or clearance fit with the mounting bracket 2, the terminal 13 can be located in a relatively sealed cavity defined by the fire-proof cover 3, thereby having good fire-proof performance. It should be noted that both end surfaces of the heating body 1 in the length direction are end surfaces of the heating body 1, a peripheral side surface of the heating body 1 is located between the two end surfaces of the heating body 1, and the peripheral side surface of the heating body 1 includes a plurality of side surfaces.

Further, in some alternative examples, as shown in fig. 3-5, outlet 31 is formed in wall 32 and is disposed adjacent second end 12 relative to terminal 13, and passageway 101 is located on a side of outlet 31 remote from second end 12. It should be noted that although the wire-passing channel 101 is located on the side of the outlet 31 far from the second end 12, the wire-passing channels 101 are not required to be located on the same side wall of the surrounding wall 32 as the outlet 31, and may be designed according to actual situations.

Thus, the power cord 5 connected to the connection terminal 13 led out from the first end 11 can be led through the wire passage 101 in the direction from the first end 11 to the second end 12 and then led out through the outlet 31, so that when the connection terminal 13 is on fire, the flame direction is opposite to the extending direction of the power cord 5, and the risk of the flame running out from the outlet 31 along the power cord 5 can be reduced. In short, according to the fire-proof cover 3 of some embodiments of the present invention, by the above-mentioned design of the positions of the outlet 31 and the wire-passing channel 101, the problem that the flame from the terminal 13 is emitted from the outlet 31 along the power line 5 can be effectively improved, so as to further improve the fire-proof performance and the safety performance.

Alternatively, as shown in fig. 3 and 5, the outlet 31 may also penetrate through one side end face of the surrounding wall 32 close to the second end 12, that is, the outlet 31 may penetrate through the surrounding wall 32 in a direction away from the routing channel, so that the outlet 31 can be very easily processed and formed, and the outlet 31 is designed to easily realize the outlet of the power line 5.

Alternatively, in some embodiments, as shown in fig. 3 to 5, an outwardly concave first groove 33 is formed on an inner wall surface of the surrounding wall 32, an inwardly concave second groove 22 is formed on an outer wall surface of the mounting bracket 2, and the second groove 22 and the first groove 33 correspond to define the wire passage 101 together. From this, can guarantee simply and effectively that the area of crossing wire duct 101 is enough for cross the width of wire duct 101 on the circumference of bounding wall 32 and need not too big, thereby can improve and form clearance fit or sealed complex area between bounding wall 32 and installing support 2, further improve fire behavior.

Optionally, as shown in fig. 3 to 5, an outwardly protruding first protrusion 34 is formed on the surrounding wall 32, and a first groove 33 is formed on the inner surface of the surrounding wall 32 corresponding to the first protrusion 34, so as to ensure that the thickness of the surrounding wall 32 is relatively uniform, and a large wall thickness reduction phenomenon cannot be formed at the first groove 33, so that the overall fire-proof performance of the fire-proof cover 3 can be improved.

In some embodiments of the present invention, as shown in fig. 2, 3 and 5, the outer surface of the surrounding wall 32 is formed with a retaining structure 35, the retaining structure 35 is located on the side of the outlet 31 away from the second end 12, and the retaining structure 35 is adapted to limit the wire harness tie 6. It should be noted that although the latching structure 35 is located on the side of the outlet 31 away from the second end 12, the latching structure 35 and the outlet 31 are not required to be located on the same side wall of the surrounding wall 32, and may be designed according to actual circumstances. For example, in the example shown in fig. 5, when the outlet 31 is provided on the first sidewall 321, the detent structure 35 may be provided on at least one of the first sidewall 321, the second sidewall 322, and the third sidewall 323.

Thus, after the power cord 5 is drawn out from the outlet 31, the cord can be stroked outside the fire-proof cover 3 in the direction from the second end 12 to the first end 11, and then the power cord 5 can be bound to the fire-proof cover 3 by using the harness binding band 6, so that the stability of the power cord 5 is improved, and the connection reliability of the power cord 5 is further improved. And, carry on spacingly to pencil ribbon 6 through setting up screens structure 35 to can improve the reliability and the stability that power cord 5 was binded to pencil ribbon 6.

In some embodiments of the present invention, as shown in fig. 3 and 5, the fire-proof cover 3 includes a first sidewall 321 located at a side of the first end 11, the outlet 31 penetrates through two side surfaces of a thickness of the first sidewall 321 and is disposed close to the second end 12 relative to the terminal 13, and the wire passage 101 is formed between the first sidewall 321 and the mounting bracket 2 and located at a side of the outlet 31 away from the second end 12. Therefore, the power line 5 connected to the connection terminal 13 led out from the first end 11 can be led through the wire passage 101 along the direction from the first end 11 to the second end 12 and then led out through the outlet 31, so that when the connection terminal 13 is on fire, the flame direction is opposite to the extending direction of the power line 5, and the risk that the flame is blown out from the outlet 31 along the power line 5 can be reduced. In short, by the design of the outlet 31 and the wire passage 101, the problem that the flame of the terminal 13 is flaming out from the outlet 31 along the power line 5 can be effectively improved, so that the fireproof performance and the safety performance are further improved.

Further, as shown in fig. 3 and fig. 5, the outlet 31 may also penetrate through a side end surface of the first side wall 321 near the second end 12, that is, the outlet 31 may penetrate through the first side wall 321 in a direction away from the routing channel, so that the outlet 31 can be very easily machined and formed, and the outlet 31 is designed to easily realize the outlet of the power line 5.

Of course, the utility model is not limited thereto, for example, in other embodiments of the utility model, the outlet 31 may also be processed by providing a circular or other through hole on the first sidewall 321, which is not described herein again. For example, in other embodiments of the present invention, the outlet 31 may also be defined between an end surface of the first sidewall 321 near the second end 12 and the mounting bracket 2, so that it is not necessary to directly machine an opening on the first sidewall 321, and details thereof are not described herein.

Alternatively, as shown in fig. 3 and 5, the first sidewall 321 is formed with a first protrusion 34 protruding outward, the first protrusion 34 is located on a side of the outlet 31 away from the second end 12, a first groove 33 is formed on an inner surface of the first sidewall 321 corresponding to the first protrusion 34, and the first groove 33 forms at least a part of the wire passing channel 101. From this, can guarantee simply and effectively that the area of wire passing channel 101 is comparatively enough, the power cord 5 of being convenient for walks the line, reduces power cord 5 by extruded risk to, can guarantee that the thickness of leg 32 is comparatively even, can not form great wall thickness attenuate phenomenon in first recess 33 department, thereby can improve the holistic fire behavior of fire prevention cover 3.

Further, as shown in fig. 3 to 5, a second groove 22 recessed inward is formed at a position of the mounting bracket 2 opposite to the first projection 34, and the second groove 22 corresponds to the first groove 33 to define the wire passage 101 together. Therefore, the enough area of the wire passing channel 101 can be better ensured, the width of the wire passing channel 101 in the circumferential direction of the first side wall 321 does not need to be too large, and the first side wall 321 and the mounting bracket 2 can form relatively large-area clearance fit or sealing fit at the position where the wire passing channel 101 is not formed, so that the fireproof performance is further improved.

In some embodiments of the present invention, as shown in fig. 3 and 5, the fire-proof cover 3 includes a second side wall 322 disposed opposite to the first side wall 321, an outer surface of the first side wall 321 and an outer surface of the second side wall 322 are respectively formed with a retaining structure 35, the retaining structure 35 is located on a side of the outlet 31 far from the second end 12, and the retaining structure 35 is adapted to retain the wire harness tying band 6. Thus, after the power cord 5 is drawn out from the outlet 31, the cord can be stroked outside the fire-proof cover 3 in the direction from the second end 12 to the first end 11, and then the power cord 5 can be bound to the fire-proof cover 3 by using the harness binding band 6, so that the stability of the power cord 5 is improved, and the connection reliability of the power cord 5 is further improved. And, carry on spacingly to pencil ribbon 6 through setting up screens structure 35 to can improve the reliability and the stability that power cord 5 was binded to pencil ribbon 6. In addition, because the screens structure 35 sets up on relative first lateral wall 321 and second lateral wall 322, can further improve the restraint reliability to pencil ribbon 6 to, set up outlet 31 and screens structure 35 simultaneously on first lateral wall 321, be convenient for operate at the same side of fire prevention cover 3, improve the convenience of operation.

Therefore, the mounting bracket 2 and the heating body 1 are connected from two opposite sides, and the connection reliability of the mounting bracket 2 and the heating body 1 can be improved. Moreover, the connecting piece on one side can be simultaneously connected with the fireproof cover 3, so that the connecting piece arranged at other positions is omitted, the integral structure is simplified, and the assembly efficiency is improved.

For example, in some specific examples, a plurality of first connection holes are formed in the first frame wall 23, a plurality of first screw holes are formed in a side of the heating body 1 facing the first frame wall 23, a plurality of second connection holes 241 are formed in the second frame wall 24, a plurality of second screw holes are formed in a side of the heating body 1 facing the second frame wall 24, a plurality of matching holes 3221 are formed in the second side wall 322, the plurality of first connection holes correspond to the plurality of first screw holes one to one, the first connection members are first screws, the first screws penetrate through the first connection holes and are in threaded connection with the first screw holes, the plurality of second connection holes 241 correspond to the plurality of second screw holes one to one, the plurality of matching holes 3221 also correspond to the plurality of second connection holes 241 one to one, the second connection members are second screws, and the second screws penetrate through the matching holes 3221 and the second connection holes 241 and are in threaded connection with the second screw holes.

For example, the first connecting structure 41 may be a connecting hole, and the second connecting structure 42 may also be a connecting hole, so that the mounting base 4 can be connected to the heating body 1 and the corresponding structural member of the household appliance by a screw penetrating through the connecting hole.

Next, an air conditioning apparatus according to an embodiment of the second aspect of the present invention is described.

It should be noted that the specific type of the air conditioning apparatus is not limited, and the air conditioning function is not limited. For example, it may be an air temperature conditioning device, such as an air conditioner; also for example, it may be an air cleaning apparatus such as an air cleaner; for another example, the air humidifying device may be an air humidifying device, such as a humidifier, etc., which is not limited or described herein. For simplicity of description, the air conditioning device is only described as an air conditioner, and it is obvious to those skilled in the art after reading the technical solutions of the present application that the air conditioning device is a specific embodiment of other types of air conditioning devices besides an air conditioner. It should be noted that the air conditioner according to the embodiment of the present invention is not limited in function, and may have, for example, only a function of adjusting the air temperature, and may further have, in addition to the function of adjusting the air temperature, at least one auxiliary function of adjusting the air cleanliness (i.e., a cleaning function), the air humidity (i.e., a humidifying function), the air freshness (i.e., a fresh air function), and the like, and is not limited herein.

In some embodiments of the present invention, an air conditioning apparatus may include: a ventilation component for inducing a flow of air to exchange heat with a heat exchange component, and a heat exchange component comprising an electrical heating assembly 100 according to an embodiment of the first aspect of the utility model. Thereby, the air flow circulation and the heating of the air flow can be realized. The type of the ventilation component is not limited, and may include an axial flow fan, a cross flow fan, a centrifugal fan, and the like. In addition, the relative positions of the ventilation member and the heat exchange member are not limited, and the ventilation member may be located upstream and/or downstream of the heat exchange member. In addition, the heat exchange component may only include the electric heating assembly 100 according to the embodiment of the first aspect of the present invention, or the heat exchange component may include a heat exchange device such as a heat exchanger in addition to the electric heating assembly 100 according to the embodiment of the first aspect of the present invention.

Therefore, according to the air conditioning equipment of the embodiment of the utility model, when the connection terminal 13 of the electric heating component 100 is in poor contact with the power line 5 or the connection terminal 13 has poor quality, and the whole heat generation reaches the ignition point, the fire-proof cover 3 can seal the flame inside the fire-proof cover 3, and because the space and the gap between the fire-proof cover 3 and the mounting bracket 2 are relatively small (for example, the fire-proof cover 3 and the mounting bracket 2 can be in clearance fit), which is equivalent to a relatively closed cavity, the flame can be naturally extinguished due to lack of oxygen in a short time after burning (at least, compared with the case of not arranging the fire-proof cover 3, the flame can be extinguished due to lack of oxygen), so that good fire-extinguishing and fire-proof effects are achieved. It can be understood that the fire-proof cover 3 described herein is made of a fire-proof material, so as to have a fire-proof effect, thereby improving the reliability and fire-proof performance of the air conditioning equipment.

Some air conditioners in the related art are provided with an electric heating device PTC (Positive Temperature Coefficient thermistor), the connection mode of the PTC is a connector lug led out from a PTC end and is connected with a wire end of an electric control device, an insulating part and a thermal shrinkage sleeve are sequentially sleeved at the connection part of the connector lug and the wire end outside the PTC end, but the PTC end is not completely wrapped, namely the front end of the PTC end is exposed outside and has no fireproof measure, at the moment, peripheral objects close to the PTC end inside the air conditioner need to be additionally provided with fireproof metal plates or the peripheral objects need to be made of fireproof materials in 5VA grade, so that fire prevention is guaranteed. If the PTC tip burns, a significant amount of smoke is carried over, causing a user to be panic and presenting a certain risk. According to the air conditioning device of the present invention, when being an air conditioner, the above technical problem can be solved more effectively by providing the electric heating assembly 100 according to the embodiment of the present invention.

Other configurations of air conditioning apparatus according to embodiments of the present invention, such as air deflectors, etc., and operations thereof, are known to those of ordinary skill in the art and will not be described in detail herein.

The fire-proof cover 3 is fixed to the mounting bracket 2 by screws through the fitting holes 3221 and to the heating body 1 by the screws so that the connection terminals 13 are enclosed in the fire-proof cover 3. The wiring terminal 13 is connected with the power line 5, and the power line 5 is led out through the outlet 31, so that the fireproof cover 3 and the mounting bracket 2 form a relatively closed space. When the wiring terminal 13 is bad to cause heating combustion, the fire-proof cover 3 can prevent the flame from spraying out, and the closed space can extinguish the flame quickly, so that the electric heating assembly 100 achieves the fire-proof effect.
