Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of heating equipment, and specifically provides a skirting line warmer. BACKGROUND

[0002] The skirting line electric heater is a heating device in the form of a skirting line (ground line). The skirting line electric heater combines the skirting line and the electric heater organically, occupies no space, and achieves the purpose of heating.

[0003] The existing skirting line warmer generally sets the air inlet at the bottom side and the air outlet at the top side, so as to utilize the natural convection phenomenon of hot air floating up and cold air sinking down, make indoor air flow, and achieve the effect of overall heating. When the cold air enters the skirting line warmer from the air inlet of the skirting line warmer, and exchanges heat with the heating device in the skirting line warmer, hot air is generated and flows out from the air outlet of the skirting line warmer. The hot air rises along the periphery of the room, forming a hot curtain effect, so as to uniformly raise the temperature of the entire room. This design enables the skirting line warmer to quickly heat the room, and the temperature distribution is uniform, and the temperature difference at each point in the room is small.

[0004] However, the air outlet of the existing skirting line warmer is generally fixed in opening degree, and cannot be flexibly adjusted according to the actual use scene and user demand. In this way, when the indoor space is small, the temperature is high, or the user has a low demand for heat emission, the air outlet with fixed opening degree continuously emits a large amount of heat, so that the indoor temperature is too high, not only causing energy waste, but also making the user feel uncomfortable. In addition, when the indoor space is large and the temperature is low, the air outlet with fixed opening degree may not be able to provide enough heat, and it is difficult to quickly and effectively raise the indoor temperature to a comfortable level. At the same time, the air outlet of the existing skirting line warmer is directly exposed, lacks a protection structure, is easy to accumulate dust, and affects the service life and heat dissipation effect of the warmer. SUMMARY

[0005] One purpose of the utility model is to solve the problem that the existing skirting line warmer cannot flexibly adjust the opening degree of the air outlet according to the actual use scene and demand of the user.

[0014] Optionally, the arc-shaped baffle is provided with a second plug-in hole, and the track frame further comprises a second fixing portion located at the other end of the arc-shaped portion, the second fixing portion being inserted into the second plug-in hole to prevent the part of the track frame away from the first fixing portion from shaking.

[0015] Optionally, the second fixing portion is perpendicular to the first fixing portion and located outside the radial direction of the arc-shaped portion.

[0016] Optionally, the arc-shaped baffle is provided with a plurality of connecting holes; the shell is provided with a plurality of mounting holes on one side in the width direction of the whole air outlet, the mounting holes corresponding to the connecting holes one by one; and the toe-kick heater further comprises a connecting member, the connecting member passing through the connecting holes and the mounting holes to fix the arc-shaped baffle to the shell.

[0017] Optionally, the shielding cover is in a sheet structure made of flexible material; the shielding cover comprises at least one track sleeve penetrated by the track frame, each track sleeve corresponding to one track frame so that the shielding cover is sleeved on the track frame through the track sleeve.

[0018] Optionally, a heat reflection layer is arranged on the side of the shielding cover close to the air outlet to reflect heat at the air outlet; and a dustproof layer is arranged on the side of the shielding cover away from the air outlet.

[0019] Optionally, the heat reflection layer is made of aluminum foil material; and the dustproof layer is made of wear-resistant cloth.

[0020] Based on the foregoing description, those skilled in the art can understand that, in the technical solutions of the baseboard heater described above, at least one track frame is arranged across the air outlet, a shielding cover is installed on the track frame, and the shielding cover is capable of sliding in the extension direction of the track frame, so that the opening degree of the air outlet can be controlled, and the baseboard heater can be flexibly adjusted according to actual use scenarios and requirements. In addition, the air outlet with a smaller opening degree can also increase the flow rate of air, so that dust accumulation at the air outlet can be effectively avoided when the baseboard heater is working.

[0021] Further, the track frame has an arc-shaped portion, and the shielding cover is guided to slide by the arc-shaped portion, so that the flow direction of hot air at the air outlet can be changed, and users in the corresponding direction can quickly feel the temperature rise.

[0022] Further, the arc-shaped baffle is arranged to clamp the shielding cover together with the track frame, so as to prevent the shielding cover from sliding under the action of its own elasticity, and the stability of the opening degree of the air outlet is ensured.

[0023] Further, the first fixing portion and the second fixing portion of the track frame are perpendicular to each other, the first fixing portion is inserted into the shell, and the second fixing portion is inserted into the arc-shaped baffle, so that the track frame and the arc-shaped baffle can be fixed and supported to each other, and the structure is more firm. In addition, compared with the case that the first fixing portion and the second fixing portion of the track frame are fixed to the shell respectively, and the arc-shaped baffle and the track frame are fixed to the shell respectively, this fixing mode is simpler as a whole.

[0024] Further, on the basis of the insertion of the arc-shaped baffle into the second fixing portion of the track frame, the arc-shaped baffle and the shell are further fixed together by the connecting member, and the distance between the arc-shaped baffle and the track frame is also limited, so as to avoid that the distance is too large or too small.

[0025] Further, the heat reflection layer is arranged on the side of the shielding cover close to the air outlet to reflect heat at the air outlet, so as to improve the user's heating experience.

[0067] Furthermore, in other embodiments of this utility model, those skilled in the art will understand that the second fixing part 313 is omitted.

[0068] Continue reading Figure 7 In some embodiments of this utility model, the first fixing part 312 extends along the tangent of the arc-shaped part 311 with its connection point with the arc-shaped part 311 as the tangent point, and a pin hole 3121 is provided on the first fixing part 312. The first fixing part 312 is adapted to the first insertion hole 1201 and is inserted into the first insertion hole 1201 so that the pin hole 3121 is located inside the housing 100.

[0069] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the skirting board heater 001 further includes a fixing pin 320 adapted to the pin hole 3121. The fixing pin 320 is inserted into the pin hole 3121 to fix the first fixing part 312 to the housing 100.

[0070] from Figure 1As can be seen, the fixing pin 320 can be a tapered pin. Of course, the fixing pin 320 can also be provided as a cylindrical pin or replaced by a combination of a bolt and a nut according to the needs of those skilled in the art.

[0071] As shown in Figure 8 some embodiments of the present application, the shielding cover 400 is a sheet structure made of a flexible material. Moreover, the shielding cover 400 comprises at least one track sleeve 401 penetrated by the track frame 310, each track sleeve 401 corresponding to one track frame 310, so that the shielding cover 400 is sleeved on the track frame 310 through the track sleeve 401, specifically, on the outer side of the arc-shaped portion 311.

[0072] As shown in Figure 9 some embodiments of the present application, the shielding cover 400 is provided with a heat reflection layer 410 on the side close to the air outlet 101 to reflect the heat at the air outlet 101.

[0076] Referring back to Figure 3 and Figure 4 , in some embodiments of the present application, the arc-shaped baffle 510 is fixedly connected to the housing 100 at the end away from the first fixed portion 312. The arc-shaped baffle 510 shields a part of the track frame 310 and clamps the shielding cover 400 together with the track frame 310 to prevent the shielding cover 400 from stretching and sliding under the action of its own elasticity.

[0077] As shown in Figure 10 some embodiments of the present application, the arc-shaped baffle 510 is provided with a second plug-in hole 511, which is adapted to the second fixed portion 313 of the track frame 310, so that the second fixed portion 313 is inserted into the second plug-in hole 511, thereby preventing the part of the track frame 310 away from the first fixed portion 312 from shaking.

[0078] As can be seen from Figure 10 , in some embodiments of the present application, the second fixed portion 313 is perpendicular to the first fixed portion 312 and located on the outer side in the radial direction of the arc-shaped portion 311.

[0079] It should be noted that the vertical between the second fixing part 313 and the first fixing part 312 is not the mathematical vertical. The vertical here aims to indicate that the second fixing part 313 and the first fixing part 312 have an included angle, and the included angle is large enough to prevent the fixed rail frame 310 from shaking.

[0080] Continuing to refer to Figure 10 , the arc-shaped baffle 510 is provided with a plurality of connecting holes 512, which correspond one-to-one with the mounting holes 1202 on the shell 100.

[0083] Further, the connecting member 520 can be a bolt, a screw, a rivet or the like.

[0084] Exemplarily, the connecting member 520 is a bolt, and the mounting hole 1202 on the top cover 120 is a threaded hole, so that the bolt is screwed into the mounting hole 1202 after penetrating the connecting hole 512.

[0085] In the process of assembling the skirting line heater 001 of the utility model, the arc-shaped baffle 510 can be first fixed to the top cover 120 through the connecting member 520. Then, the rail frame 310 passes through the rail sleeve 401 of the shielding cover 400, and the second fixing part 313 of the rail frame 310 is inserted into the second plug-in hole 511 of the arc-shaped baffle 510. Subsequently, the rail frame 310 is rotated, and the first fixing part 312 of the rail frame 310 passes through the first plug-in hole 1201. Then, the fixing pin 320 is installed into the pin hole 3121 of the first fixing part 312. Finally, the top cover 120 is installed onto the shell body 110.

[0086] When the skirting line heater 001 of the utility model is used, the user can adjust the shielding degree of the shielding cover 400 to the air outlet 101, i.e. the opening degree of the air outlet 101, according to the need. When the shielding cover 400 is contracted, the user can push the excess part of the shielding cover 400 into the space between the arc-shaped baffle 510 and the rail frame 310, and the shielding cover 400 is clamped by the arc-shaped baffle 510 and the rail frame 310, preventing the shielding cover 400 from sliding under the action of its own elasticity and affecting the opening degree of the air outlet 101.

[0087] When the skirting line heater 001 of the utility model is not used, the user can completely shield the air outlet 101 with the shielding cover 400 to prevent dust from falling on the air outlet 101.

[0088] Based on the foregoing description, those skilled in the art can understand that the skirting line heater 001 of the utility model not only can be flexibly adjusted according to the actual use scene and the needs of the user, but also the smaller opening degree of the air outlet 101 can increase the flow rate of the air, so that dust can be effectively avoided at the air outlet 101 when the skirting line heater 001 is working. Moreover, the skirting line heater 001 of the utility model can completely shield the air outlet 101 with the shielding cover 400 when not in use, preventing dust from falling on the air outlet 101.

[0089] So far, the technical scheme of the utility model has been described in combination with the foregoing multiple embodiments, but those skilled in the art can easily understand that the protection scope of the utility model is not limited to these specific embodiments. Without deviating from the technical principles of the utility model, those skilled in the art can split and combine the technical schemes in the above-mentioned embodiments, or make equivalent changes or replacements to the related technical features, and any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the utility model will fall within the protection scope of the utility model.
