Description

Technical Field

[0001] This utility model belongs to the technical field of heating equipment, and specifically provides a heater. Background Technology

[0002] In the field of heating equipment technology, to improve the radiant heating effect of heaters, some existing heaters are equipped with radiant heating devices and heat reflection components. The heat reflection components can reflect the heat generated by the radiant heating device out of the radiant heat dissipation vents, thereby enhancing the radiant heating performance. However, in actual use, it has been found that the heat reflection components absorb some heat themselves when reflecting heat, causing the temperature to rise. This excess heat is usually not effectively utilized, resulting in low heat utilization rate of the heating equipment. Utility Model Content

[0003] One objective of this invention is to solve the problem of low heat utilization rate in existing heaters.

[0004] To achieve the above objectives, this utility model provides a heater, comprising:

[0005] The housing includes an air inlet at its bottom, an air outlet at its top, and an airflow channel connecting the air inlet and the air outlet; the housing also includes a radiant heat dissipation vent located on its front side.

[0006] A contact heating device is arranged in the air flow channel and comes into contact with the air in the air flow channel to heat the air in the air flow channel and force the air to flow from the air inlet to the air outlet.

[0007] A radiant heating device is aligned with the radiant heat dissipation port;

[0008] A heat-reflecting component is arranged in the airflow channel and located between the contact heating device and the air inlet. The heat-reflecting component is used to reflect the heat generated by the radiant heating device out of the radiant heat dissipation port.

[0009] Optionally, the radiant heating device is a light radiation heating tube;

[0010] The heat reflective component includes an arc-shaped plate that protrudes towards the rear of the heater to increase the contact area between the arc-shaped plate and the airflow channel.

[0011] Optionally, the housing is provided with air inlets on the bottom side of the arc-shaped plate and on the rear side of the arc-shaped plate, respectively.

[0012] Optionally, the airflow channel has a constriction section at the arc-shaped plate;

[0013] The distance between the contact heating device and the rear panel of the housing is smaller than the distance between the contact heating device and the front panel of the housing, so that the contact heating device is aligned with the contraction section.

[0014] Optionally, the axial direction of the radiant heating tube is parallel to the lateral direction of the heater.

[0015] Optionally, the heat reflector further includes an upper mounting plate and a lower mounting plate, which are respectively disposed on the upper and lower edges of the radiant heat dissipation port and extend toward the rear side of the heater. The upper mounting plate and the lower mounting plate are respectively fixedly connected to the arc-shaped plate.

[0016] Optionally, the lower mounting plate is spaced apart from the air inlet located on the bottom side of the arc-shaped plate to avoid obstructing the air inlet located on the bottom side of the arc-shaped plate.

[0017] Optionally, the heater further includes a support leg disposed at the bottom of the housing.

[0018] Optionally, the air outlet is tilted towards the upper front of the heater, and the angle between the air outlet and the horizontal plane is selected from any value between 10 degrees and 30 degrees.

[0019] Optionally, the heater may also include a clothes rack.

[0020] Optionally, the clothes rack is configured in a U-shape, so that the clothes rack has a clothes drying rod and two opposing cantilever arms. The clothes rack is rotatably connected to the left and right side walls of the housing through the two cantilever arms, so that the clothes drying rod can be flipped to the front and rear sides of the housing.

[0021] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by setting the heat reflection component for reflecting the heat of the radiant heating device in the airflow channel and placing it between the contact heating device and the air inlet, the residual heat on the heat reflection component is used to preheat the air flowing towards the contact heating device, thereby significantly improving the heat utilization rate.

[0022] Furthermore, by setting an arc-shaped plate that bulges towards the rear of the heater, the contact area between the arc-shaped plate and the airflow channel is increased, allowing the air to more fully absorb the residual heat on the arc-shaped plate as it flows through, thus enhancing the preheating effect.

[0023] Furthermore, by setting air inlets on the bottom and rear sides of the curved plate, the curved plate can fully contact the air flowing in from the air inlets, making full use of the residual heat on the curved plate and further improving the heat utilization rate.

[0040] like Figures 1 to 3 As shown, the heater 001 includes a housing 100, a contact heating device 200, a radiant heating device 300, and a heat reflector 400.

[0041] The casing 100 includes an air inlet 110 at its bottom, an air outlet 120 at its top, and an airflow channel 130 connecting the air inlet 110 and the air outlet 120. The casing 100 also includes a radiant heat dissipation vent 140 on its front side, with a radiant heating device 300 aligned with the radiant heat dissipation vent 140. The heat from the radiant heating device 300 (such as a heating wire or halogen tube) propagates in the form of electromagnetic waves (infrared radiation) and is directional. Aligning the heat dissipation vent with the heating device reduces the casing 100's obstruction of radiation, allowing heat to be directly directed to the target area (such as a human body or object), avoiding energy loss due to reflection within the casing 100.

[0042] The contact heating device 200 is arranged in the air flow channel 130 and comes into contact with the air in the air flow channel 130 to heat the air in the air flow channel 130 and force the air to flow from the air inlet 110 to the air outlet 120.

[0043] The heat reflection component 400 is arranged in the air flow channel 130 and located between the contact heating device 200 and the air inlet 110. The heat reflection component 400 is used to reflect the heat generated by the radiant heating device 300 out of the radiant heat dissipation port 140.

[0044] Those skilled in the art will understand that the heat reflector 400 is arranged in the airflow channel 130 and located between the contact heating device 200 and the air inlet 110. On the one hand, it can reflect the heat generated by the radiant heating device 300 out of the radiant heat dissipation port 140, thereby improving the utilization rate of radiant heat. On the other hand, after absorbing heat, the heat reflector 400 increases in temperature and can preheat the air flowing towards the contact heating device 200, thereby further improving the heat utilization rate and air heating efficiency.

[0045] Furthermore, the traditional convection heater 001 utilizes natural air convection. After the air near the heating device is heated, the airflow rises, and the cold air at the bottom is drawn in. The hot air rises directly to the top of the heater 001. If a person stands in front of the heater 001, the heating effect will be poor.

[0046] In contrast, the contact heating device 200 of this invention distributes heat evenly throughout the room via natural convection, ensuring large-area heating; simultaneously, the radiant heating device 300 directly radiates heat to the human body, achieving rapid heating. When used in combination, these two methods significantly improve overall heating efficiency. The radiant heating device 300 can quickly provide localized warmth, making it particularly suitable for immediate needs in cold environments.

[0047] like Figure 2 , 3 As shown, in some embodiments of this utility model, the radiant heating device 300 is a light radiation heating tube 310. The heat reflection component 400 includes an arc-shaped plate 410, which protrudes towards the rear side of the heater 001 to increase the contact area between the arc-shaped plate 410 and the air flow channel 130, so that the air can more fully absorb the residual heat on the arc-shaped plate 410 when it flows through, thereby enhancing the preheating effect.

[0048] Furthermore, the cross-section of the arc plate 410 can be C-shaped, which surrounds the light radiation heating tube 310 in a semi-enclosed form. The opening of the C-shape faces the radiation heat dissipation port 140, which can better collect and reflect the heat generated by the light radiation heating tube 310, reduce heat loss, and improve the reflection efficiency of radiant heat.

[0049] In some embodiments of this invention, the arc-shaped plate 410 is made of aluminum alloy. A highly reflective aluminum film is coated on the side of the arc-shaped plate 410 closest to the radiant heating tube 310, which can reflect the light from the radiant heating tube 310 forward. The aluminum alloy material has good thermal conductivity and strength, which facilitates heat transfer and ensures the structural stability of the arc-shaped plate 410. After being coated with a highly reflective aluminum film, the reflectivity of the arc-shaped plate 410 is greatly improved, which can reflect the light from the radiant heating tube 310 forward more efficiently and enhance the radiant heating effect.

[0050] As those skilled in the art will understand, since the curved plate 410 is made of aluminum alloy, while reflecting the light from the radiant heating tube 310, the curved plate 410 absorbs heat due to its low temperature. This invention utilizes this heat from the curved plate 410 to preheat the air in the airflow channel 130.

[0051] In some embodiments of this utility model, the light radiation heating tube 310 can be an infrared light radiation heating tube 310, or it can be a halogen light heating tube.

[0052] In some embodiments of this utility model, the contact heating device 200 can be any type of device that achieves heating through natural air convection (e.g., heating wire, PTC element). It utilizes the characteristic that the density of air decreases and flows upward after being heated to drive heat circulation, without the need for forced convection components such as fans.

[0053] Continue reading Figures 1 to 3 In some embodiments of this utility model, the casing 100 is provided with air inlets 110 on the bottom side and the rear side of the arc-shaped plate 410, respectively, which increases the air intake area, can draw in more cold air, increase air flow, and improve air heating efficiency and heating effect. Moreover, both air inlets 110 are positioned directly opposite the arc-shaped plate 410, so that the incoming air directly contacts the arc-shaped plate 410, making full use of the residual heat on the arc-shaped plate 410 and further improving the heat utilization rate.

[0054] like Figure 3As shown, the airflow channel 130 has a constriction section 131 at the arc-shaped plate 410. The distance between the contact heating device 200 and the rear side plate 160 of the housing 100 is smaller than the distance between the contact heating device 200 and the front side plate 150 of the housing 100, so that the contact heating device 200 is aligned with the constriction section 131, ensuring that the airflow makes full contact with the contact heating device 200. The constriction section 131 at the arc-shaped plate 410 reduces the cross-sectional area of ​​the flow channel. According to Bernoulli's equation, the airflow velocity increases significantly when passing through the constriction section 131.

[0055] like Figure 2 , 3 As shown, in some embodiments of this utility model, the axial direction of the light radiation heating tube 310 is parallel to the transverse direction of the heater 001.

[0056] Continue reading Figure 2 and Figure 3 In some embodiments of this utility model, the heat reflector 400 further includes an upper mounting plate 420 and a lower mounting plate 430. The upper mounting plate 420 and the lower mounting plate 430 are respectively disposed on the upper edge and lower edge of the radiant heat dissipation port 140 and extend toward the rear side of the heater 001. The upper mounting plate 420 and the lower mounting plate 430 are respectively fixedly connected to the arc-shaped plate 410. The upper mounting plate 420 and the lower mounting plate 430 can be fixed to the arc-shaped plate 410 by any feasible method such as screw connection, welding, or snap-fit.

[0057] Those skilled in the art will understand that the upper mounting plate 420 and the lower mounting plate 430 are respectively disposed on the upper edge and lower edge of the radiant heat dissipation port 140 and fixedly connected to the arc plate 410, providing a stable mounting structure for the arc plate 410, ensuring the stability of the heat reflection component 400 during the operation of the heater 001, and enabling it to continuously and effectively perform the functions of heat reflection and waste heat utilization.

[0058] Continue reading Figure 3 In some embodiments of this utility model, the lower mounting plate 430 and the air inlet 110 located on the bottom side of the arc plate 410 are spaced apart to avoid blocking the air inlet 110 located on the bottom side of the arc plate 410, thereby maximizing the area of ​​the air inlet 110 and increasing the air intake volume.

[0059] like Figure 1 , 2 As shown, in some embodiments of this utility model, the heater 001 further includes a support leg 500, which is disposed at the bottom of the housing 100. The support leg 500 at the bottom of the housing 100 keeps the heater 001 at a certain distance from the ground, which on the one hand prevents the bottom of the housing 100 from getting damp, and on the other hand facilitates the smooth entry of air from the air inlet 110, and also makes it convenient for the user to adjust the position of the heater 001.

[0060] like Figure 3 As shown, in some embodiments of this utility model, the air outlet 120 is inclined towards the upper front of the heater 001, and the angle between the direction of the air outlet 120 and the horizontal plane is selected from any value between 10 degrees and 30 degrees. For example, the angle between the direction of the air outlet 120 and the horizontal plane can be 10 degrees, 12 degrees, 15 degrees, 20 degrees, 25 degrees, and 30 degrees, etc.

[0061] In this embodiment, by setting the air outlet 120 within the aforementioned tilt angle range, the heated air can be blown out in a suitable direction and angle, expanding the air diffusion range and allowing the heat to be distributed more evenly in the indoor space, thereby improving heating comfort.

[0062] Furthermore, the angle between the orientation of the air outlet 120 and the horizontal plane is selected from any value between 15 degrees and 25 degrees. For example, the angle between the orientation of the air outlet 120 and the horizontal plane can be 16 degrees, 18 degrees, 21 degrees, 23 degrees, and 24 degrees.

[0063] like Figure 1 and Figure 3 As shown, in some embodiments of this utility model, the heater 001 also includes a clothes rack 600.

[0064] Continue reading Figure 1 , 3 In some embodiments of this utility model, the clothes rack 600 is U-shaped, so that the clothes rack 600 has a clothes rod 610 and two opposing cantilever arms 620. The clothes rack 600 is rotatably connected to the left and right side walls 170 of the housing 100 through the two cantilever arms 620, so that the clothes rod 610 can be flipped to the front and rear sides of the housing 100. This design expands the function of the heater 001, allowing users to use the heat emitted by the heater 001 to dry clothes, achieving multiple uses in one machine and improving the practicality of the product.

[0065] In some embodiments of this invention, the contact heating device 200 can be turned on independently to maintain the overall room temperature for a long time, suitable for energy-saving scenarios; the radiant heating device 300 can be turned on independently to achieve rapid localized heating, suitable for immediate needs in cold environments; or the contact heating device 200 and the radiant heating device 300 can be turned on simultaneously to achieve a rapid and uniform heating effect. Therefore, users can selectively turn on the heating mode according to their actual needs, avoiding unnecessary energy waste. For example, when only localized heating is needed, only the radiant heating device 300 needs to be turned on. When air convection heating and thermal radiation are used in combination, the same heating effect can be achieved with lower power, thereby reducing energy consumption.

[0066] In some embodiments of this utility model, the heater 001 is equipped with temperature monitoring and overheat protection functions. When the device temperature exceeds a set threshold, the system will automatically cut off the power to avoid safety hazards caused by high temperatures. The combined use of convection heating and radiant heating can reduce the risk of a single heating device operating for extended periods and lower the possibility of localized overheating.

[0067] In summary, this utility model improves the heat utilization rate by placing a heat reflection component 400 for reflecting the heat of the radiative heating device 300 in the air flow channel 130 and between the contact heating device 200 and the air inlet 110, and using the residual heat on the heat reflection component 400 to preheat the air flowing towards the contact heating device 200.

[0068] Furthermore, it should be noted that in the description of this utility model, the terms "coldness" and "heat" are two descriptions of the same physical state. That is, the higher the "coldness" of a target object (e.g., evaporator, air, condenser, etc.), the lower its "heat," and vice versa. A target object absorbs "coldness" while releasing "heat," and releases "coldness" while absorbing "heat." A target object retains "coldness" or "heat" to maintain its current temperature. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon; that is, a target object (e.g., evaporator) absorbs heat while refrigerating.

[0069] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.
