Description

Technical Field

[0001] This invention relates to the field of heater technology, and more particularly to a waste heat utilization radiant heater. Background Technology

[0002] Whether in the north or south, winter is generally difficult to endure. With improved living standards, most modern people have heaters in their homes. In winter, people close doors and windows to prevent cold air from entering. After using heaters for a period of time, indoor humidity decreases, leading to dry air and causing discomfort.

[0003] Chinese Patent No. CN215765342U discloses a heater that uses residual heat from heating for humidification. It includes a shell with a hot air outlet on its upper part and a cold air inlet at its lower end. A humidifying water box is attached to the side wall outside the shell. The humidifying water box is a groove-shaped structure with a closed bottom and an open top. The side wall of the shell conducts residual heat to the water in the humidifying water box, heating and evaporating the water in the humidifying water box.

[0004] There are many types of heaters. The heater mentioned above is a horizontal box heater with a humidifying water box installed directly on it. It uses waste heat to accelerate the evaporation of water in the humidifying water box to replenish the moisture in the room. However, there are a large number of vertical radiant heaters on the market, which are difficult to utilize waste heat.

[0005] In addition, the low temperatures in winter make it difficult for clothes and socks to dry, so people often use the heat from the surface of a horizontal heater to speed up the drying of small items such as socks.

[0006] The above-mentioned functions do not apply to vertical heaters. The structure of a vertical heater is described in Chinese Patent No. CN214581369U, which includes a base, a column fixed on the base, and a heating device on the top of the column. The heating device includes a reflector and a ring-shaped heating element located below the reflector. After the ring-shaped heating element heats up, it reflects the heat into the room through the reflector.

[0007] The heating element of a vertical heater is exposed to the outside and radiates to a certain area through reflection by a reflector. Existing waste heat utilization structures are difficult to apply to vertical heaters, resulting in insufficient waste heat utilization in vertical heaters. Summary of the Invention

[0008] This invention addresses the drawback of existing vertical heaters that cannot utilize waste heat by providing a radiant heater that utilizes waste heat.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0010] A waste heat utilization radiant heater includes a base, a column fixed to the base, and a heating element fixed to the top of the column. A waste heat utilization device is mounted on the column, comprising a folding drying section and a water-holding section. The folding drying section includes a support cylinder fixedly fitted outside the column and a clothesline that can be stored inside the support cylinder or horizontally extended outside the support cylinder. The water-holding section includes a water tank mounted on the base with a water inlet at the top. A waste heat conduction section is mounted on the column. The guide section includes a heat conductor, a heat-conducting column, and a follower heat-conducting part. One end of the heat conductor is clearance-fitted with the heating device, and the other end is inserted into the column. The heat-conducting column is vertically mounted between the support cylinder and the column. After the heat-conducting column descends, its bottom can be inserted into the water tank. After the heat-conducting column rises, it can be completely detached from the water tank. The follower heat-conducting part includes a heat-conducting block vertically mounted on the outer wall of the column. The heat-conducting block is provided with a guide groove for the heat-conducting column to be inserted. The end of the heat-conducting block away from the heat-conducting column passes through the column and is connected to the heat conductor.

[0011] Using the above solution, a folding drying section and a water-collecting section are installed on the column. The waste heat conduction section can simultaneously conduct heat to both the folding drying section and the water-collecting section. The folding drying section can be completely stored inside the support cylinder. When stored, the outside of the support cylinder is smooth and flat. When unfolded, all drying rods are in a horizontally limited position. Socks or clothes can be hung directly on the drying rods or hung on hooks. The unfolded drying rods are located in the middle of the column. After the heating device heats up, the reflected heat can be directly absorbed by the clothes. The moisture evaporated from the clothes can also be returned to the room, reducing indoor dryness. Secondly... Through the absorption of heat by the heat conductor, when the heating device is turned off, the residual heat on the heat conductor can still be conducted to the heat conduction column, then to the clothesline, and finally to the clothes, thus increasing the utilization of residual heat. The temperature of the heat conduction column is conducted downwards to the water in the water tank, which can increase the indoor temperature through the evaporation of water in the tank, or directly heat the water in the tank. In winter, people can remove the water tank and use the hot water inside for washing. The residual heat of this heater can be transferred to the clothesline and water tank through the heat conductor, which can not only accelerate the drying of clothes, but also increase the indoor humidity, thus making significant use of residual heat.

[0012] Preferably, a movable hinge is provided between the clothes drying rod and the support cylinder. The movable hinge includes a hinge shaft at one end of the clothes drying rod, guide bars vertically arranged on the inner wall of the support cylinder and located on both sides of the clothes drying rod, and a movable groove recessed from the bottom of the guide bars upwards, which allows the hinge shaft to be inserted and move vertically. A clearance groove is recessed at the upper end of the support cylinder, which allows the clothes drying rod to be turned outwards by 90° to abut against it.

[0013] By adopting the above scheme, an additional movable hinge is added. When the hinge shaft moves up to the highest point, the clothes drying rod and guide bar switch from the guiding state to the hinged state and can be flipped outward. When the hinge shaft moves down, the clothes drying rod and guide bar move in a guiding motion until they are stored in the support tube. The above configuration realizes the storage of the clothes drying rod inside the support tube and its unfolding outside the support tube.

[0014] Preferably, the clothes drying rod is arranged in several sets at circumferential intervals around the support cylinder.

[0015] Preferably, the heat-conducting column includes a clothes-drying heat-conducting rod that is arranged one-to-one with the clothes-drying rod, and an elastic heat-conducting component is provided inside the clothes-drying rod that elastically abuts against the clothes-drying heat-conducting rod when the clothes-drying rod is unfolded.

[0016] Using the above solution, the elastic heat-conducting component can make contact with the heat-conducting column, and can conduct the heat on the heat-conducting column to the clothes drying rod.

[0017] Preferably, the elastic heat-conducting component includes a fixed heat-conducting block embedded along the length of the clothesline, a movable heat-conducting block disposed at one end of the fixed heat-conducting block near the hinge end, and a heat-conducting elastic element fixedly connected to both of them at both ends.

[0018] Using the above solution, the setting of the elastic heat-conducting component can realize the elastic extension and retraction of the movable heat-conducting block. When the clothes drying rod is in a horizontal state, the elastic force of the heat-conducting elastic element can be used to drive the movable heat-conducting block to elastically abut against the heat-conducting column, thereby absorbing the heat from the heat-conducting column. When the clothes drying rod needs to be folded and stored, it can retract to avoid the space, so that the clothes drying rod can be stored in the support cylinder.

[0019] Preferably, the end of the clothes drying rod away from the hinge axis is provided with a heat-insulating and anti-scalding section. When the clothes drying rod is stored in the support tube, the heat-insulating and anti-scalding section is located outside the upper end of the support tube.

[0020] With the above solution, the heat-insulating and anti-scalding section extends beyond the support tube when the clothes drying rod is stored, making it easier for people to hold the clothes drying rod and lift and flip it outwards.

[0021] Preferably, the heat-conducting column includes a water-conducting rod, which is located below the clothes-drying heat-conducting rod and connected by a heat-conducting connecting ring. At least one water-conducting rod is distributed circumferentially around the heat-conducting connecting ring.

[0022] Using the above method, the heat-conducting rod conducts heat to the clothes drying rod on one side and to the water tank on the other.

[0023] Preferably, a limiting mechanism is provided between the clothes drying heat-conducting rod and the column to keep the water heat-conducting rod detached from the water tank. The limiting mechanism includes a heat-insulating lifting member provided on the upper end face of the heat-conducting column and a hanging ring provided on the upper end of the column. When the water heat-conducting rod is detached from the water tank, the heat-insulating lifting member is suspended on the hanging ring.

[0024] With the above scheme, the function of the limiting mechanism is to drive the heat-conducting column to remain in an upward and stationary state, making it easy to put the water tank in and out.

[0025] Preferably, the heating device includes a reflector, a heating element disposed below the reflector, and a mesh cover disposed below the heating element and fixed to the reflector.

[0026] Using the above solution, the heating element dissipates heat, the reflector reflects the heat into the room, and the mesh cover is used to protect the heating component and prevent people or flying insects from touching the heating element and causing safety hazards.

[0027] Preferably, a slot for inserting a column is provided on one side of the water tank, and a spray assembly for spraying water in a mist form is provided on the water tank.

[0028] Using the above solution, the water tank itself can provide indoor humidity by evaporating warm water, or it can be used directly with the spray unit. The warm water mist sprayed by the spray unit can relieve the discomfort of some rhinitis patients.

[0029] This invention, employing the above technical solutions, achieves significant technical effects: A folding drying section and a water-receiving section are installed on the column; the residual heat conduction section can simultaneously conduct heat to both sections. The folding drying section can be completely retracted into the support cylinder, resulting in a smooth and flat exterior when retracted. When unfolded, it remains in a horizontally controlled position. Socks or clothes can be hung directly on the clothesline or via hooks. The unfolded clothesline is located in the center of the column. After the heating device generates heat, the reflected heat is directly absorbed by the clothes, and the evaporated moisture from the clothes can also be returned to the room, reducing indoor humidity. Firstly, the heater absorbs heat through the heat conductor. After the heating device is turned off, the residual heat on the heat conductor can be conducted to the heat-conducting column, then to the clothesline, and finally to the clothes, thus increasing the utilization of residual heat. The temperature of the heat-conducting column is conducted downwards to the water in the tank, which can increase the indoor temperature through the evaporation of water in the tank, or directly heat the water in the tank. In winter, people can remove the water tank and use the hot water inside. The residual heat of the heater can be transferred to the clothesline and the water tank through the heat conductor, which can not only accelerate the drying of clothes, but also reduce indoor dryness, and the residual heat is significantly utilized.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0046] Example 1

[0047] A waste heat utilization radiant heater, referring to Figures 1-3 As shown, the device includes a base 7, a column 1 fixed on the base 7, and a heating device fixed on the top of the column 1. The heating device includes a reflector 2 and a heating element 10 disposed below the reflector 2. A mesh cover 3 fixed to the reflector 2 is disposed below the heating element 10. A mounting cover 101 fixed to the mesh cover 3 is disposed at the top of the column 1. A main control circuit module is disposed inside the mounting cover 101. The heating element 10 is electrically connected to the main control circuit module. The above is the prior art.

[0048] A waste heat utilization device is installed on column 1. The waste heat utilization device includes a folding drying section, a water holding section, and a waste heat conduction section. Excess heat is transferred to the folding drying section and the water holding section through the waste heat conduction section.

[0049] Combination Figures 6-9 As shown, the folding drying section includes a support cylinder 4 fixedly sleeved outside the column 1. The support cylinder 4 is made of high-temperature resistant polymer material, which can be engineering plastic, and has a rubber layer on the outside to further reduce heat loss and provide heat insulation and anti-scalding effect. A fixing flange 17 is fixed at the bottom of the support cylinder 4. The fixing flange 17 is interference-fitted onto the column 1. A clothes drying rod 5 is provided on the support cylinder 4, which can be stored inside the support cylinder 4 or horizontally unfolded outside the support cylinder 4. Several sets of clothes drying rods 5 are arranged around the support cylinder 4 at intervals. In this embodiment, eight sets are provided.

[0050] The clothesline 5 and the support cylinder 4 are connected by a movable hinge. This movable hinge includes a hinge shaft 53 at one end of the clothesline 5. Guide bars 42 are vertically arranged on the inner wall of the support cylinder 4 and on two other vertically arranged sections of the clothesline 5 for vertical lifting and lowering. A movable groove 43 is recessed upwards at the bottom of the guide bars 42, allowing the hinge shaft 53 to be inserted and move vertically. A clearance groove 41 is recessed at the upper end of the support cylinder 4, allowing the clothesline 5 to be tilted outwards by 90°. The end of the clothesline 5 furthest from the hinge shaft 53 is provided with… The clothes drying rod 5 is equipped with a heat-insulating and anti-scalding section 51 made of rubber. When the clothes drying rod 5 is stored in the support tube 4, the heat-insulating and anti-scalding section 51 is located outside the upper end of the support tube 4. The clothes drying rod 5 is made of aluminum alloy or stainless steel, preferably aluminum alloy. Aluminum alloy has the effect of slow heat absorption and fast heat dissipation, and the surface will not retain heat for a long time. When the clothes drying rod 5 is pulled out, it will quickly cool down to a temperature that is acceptable to the human body and will not easily cause burns. The heat-insulating and anti-scalding section 51 is designed to prevent hands from coming into contact with high temperature when lifting and flipping the clothes drying rod 5.

[0051] The water-receiving part is located below the support cylinder 4, combined with Figure 5 As shown, the water-containing part includes a water tank 6 with an upward-facing opening. The side wall of the water tank 6 has a recessed slot 61 for inserting a column 1. The upper end of the water tank 6 is provided with a water inlet 63, and a cap 64 is threaded onto the water inlet 63.

[0052] Combination Figures 10-13 As shown, the waste heat conduction section includes a heat conductor 11, a heat conduction column, and a follow-up heat conduction section. The heat conductor 11 is a copper wire. One end of the heat conductor 11 is wound around the mesh cover 3 and the end extends into the mesh cover 3 to fit with the heating element 10 with a gap. Several heat conductors 11 are arranged circumferentially around the column 1. In this embodiment, four heat conductors are arranged. A heat insulation layer, preferably a rubber heat insulation layer, is provided on the outer wall of the mounting cover 101. A protective member 12 is also provided outside the mounting cover 101. The number of protective members 12 is the same as that of the heat conductors 11. The protective members 12 are fixed outside the mounting cover 101 and there is a gap between the protective members 12 and the mounting cover 101 that allows the heat conductor 11 to pass through. A space is provided between the protective members 12 and the mounting cover 101. To prevent the heat conductor 11 from touching the wire block 21 of both, the heat conductor 11 and the wire block 21 are plugged into each other. A through hole 102 is provided in the protective component 12 on the column 1, through which the heat conductor 11 can pass. For ease of installation, the column 1 is preferably formed by two sections of round rods connected by threads. Fixed guide blocks 22 and fixed support blocks 23 are distributed vertically inside the column 1. The lower end of the heat conductor 11 passes through the fixed guide block 22 and connects with the heat-conducting column after connecting with the fixed support block 23. The setting of the protective component can reduce the loss of heat from the heat conductor and reduce the risk of accidental contact by the human body. The heat insulation layer is used to isolate heat conduction to the mounting cover, avoid the impact on the internal main control circuit module and prevent heat loss.

[0053] The heat-conducting column is lifted and positioned between the support cylinder 4 and the column 1, combined with... Figure 5 As shown, the heat-conducting column is made entirely of copper. The heat-conducting column includes a clothes-drying heat-conducting rod 13 that corresponds one-to-one with the clothes-drying rod 5. The number of clothes-drying heat-conducting rods 13 is the same as that of the clothes-drying rod 5. They are connected as one unit by heat-insulating connecting rings 16 and heat-conducting connecting rings 15 at both ends. The heat-insulating connecting ring 16 is located at the end closer to the heating device, and the heat-conducting connecting ring 15 is located at the end closer to the water tank 6.

[0054] After the clothes drying rod 5 is turned outward by 90°, a groove 52 communicating with the support cylinder 4 is recessed along the length direction at the upper end. An elastic heat-conducting component is provided inside the clothes drying rod 5, which elastically abuts against the clothes drying heat-conducting rod 13 when the clothes drying rod 5 is unfolded. Figure 8As shown, the elastic heat-conducting assembly includes a fixed heat-conducting block 18 fixed in the groove 52 along the length of the clothes drying rod 5, a movable heat-conducting block 19 disposed at one end of the fixed heat-conducting block 18 near the support cylinder 4, and a heat-conducting elastic element 20 fixedly disposed between the fixed heat-conducting block 18 and the movable heat-conducting block 19 for driving the movable heat-conducting block 19 to elastically abut against the clothes drying heat-conducting rod 13. The heat-conducting elastic element 20 is a spring. The fixed heat-conducting block 18, the movable heat-conducting block 19 and the spring are all made of copper. The end of the movable heat-conducting block 19 that abuts against the clothes drying heat-conducting rod 13 is set in a concave arc shape. When the clothes drying rod 5 is turned outward by 90° and limited, the movable heat-conducting block 19 automatically and elastically abuts against the clothes drying heat-conducting rod 13. The clothes drying heat-conducting rod 13 absorbs the heat radiated by the heating device and the heat of the heat conductor 11 and transfers the heat to the movable heat-conducting block 19, the heat-conducting elastic element 20 and the fixed heat-conducting block 18. When towels, clothes and socks are hung on the clothes drying rod 5, these residual heat can be used to achieve the effect of rapid drying.

[0055] A water-conducting rod 14 extends downward from the lower end of the heat-conducting connecting ring 15, combined with... Figures 4-5 As shown, at least one water-conducting rod 14 is distributed circumferentially around the heat-conducting connecting ring 15. In this embodiment, three rods are provided. The upper end face of the water tank 6 is provided with a funnel-shaped guide member 62 that is larger at the top and smaller at the bottom. The guide member 62 allows the water-conducting rod 14 to be inserted and extend to the bottom of the water tank 6. In order to facilitate the removal of the water tank 6, the entire heat-conducting column is raised and lowered on the column. The aforementioned heat-insulating connecting ring 16 and heat-conducting connecting ring 15 are sleeved on the column 1. A limiting mechanism is provided between the heat-insulating connecting ring 16 and the mounting cover 101 to limit the heat-conducting column when it rises until the water-conducting rod 14 is removed from the water tank 6. The limiting mechanism includes a heat-insulating lifting member 9 provided on the upper end face of the clothes-drying heat-conducting rod and a hanging ring 8 provided on the lower end of the mounting cover. There are two hanging rings symmetrically arranged. The heat-insulating lifting member 9 includes two insert rods that can be inserted into the hanging ring 8 respectively.

[0056] The column 1 is also provided with a follow-up heat conduction part that maintains good heat conduction performance as the clothes drying heat conduction rod 13 rises and falls. Several sets of follow-up heat conduction parts are distributed around the column. In this embodiment, four sets are provided. The follow-up heat conduction part includes a heat conduction block 24 that is vertically set outside the column 1. The heat conduction block 24 is made of copper. One end of the heat conduction block 24 inserted into the column 1 is connected to the heat conductor 11. The end of the heat conduction block 24 located outside the column 1 is provided with a guide groove 25 through which the clothes drying heat conduction rod 13 can pass. As the clothes drying heat conduction rod 13 rises and falls, the clothes drying heat conduction rod 13 is always in a sliding guide state with the heat conduction block 24. Therefore, the heat on the heat conductor 11 can always be conducted to the clothes drying heat conduction rod 13, and then transferred by the clothes drying heat conduction rod 13 to the clothes drying rod 5 and the water heat conduction rod 14 respectively.

[0057] The water in the water tank 6 can be directly removed for cleaning. In winter, hot or warm water can be obtained directly to avoid cold hands. The cover 64 can also be opened directly to allow the water inside to evaporate and provide indoor moisture. When replacing the water tank 6, the heat-insulating pull piece 9 can be pulled up directly until it contacts the hanging ring 8 and then the water tank 6 can be pulled out directly to fill with water. Alternatively, the cover 64 can be opened directly to fill with water.

[0058] The support cylinder 4 itself has good heat insulation effect, which can delay the dissipation of heat from the heat-conducting column. Even after the heating device is turned off, it can still provide heat to the clothes drying rod 5 and the water tank 6 for a certain period of time, further improving the utilization efficiency of waste heat. The distance between the heat conductor 11 and the heating element 10 can be adjusted by using tools such as hooks or tweezers, thereby adjusting the temperature of the heat conductor 11.

[0059] When in use, if there is no need to dry clothes, the clothes drying rod 5 can be stored in the support tube 4. At this time, it is only necessary to ensure that there is enough water in the water tank 6. Insert the water heat conduction rod 14 into the water tank 6. When the heating device is working, the heat conductor 11 absorbs heat and conducts it to the water in the water tank 6 in sequence through the clothes drying heat conduction rod 13 and the water heat conduction rod 14, thereby increasing the temperature of the water inside. If clothes need to be dried, more than one clothes drying rod 5 can be selected according to the number of clothes to be dried. By pulling up and flipping the clothes drying rod 5 outward, the movable heat conduction block 19 inside the clothes drying rod 5 can be driven to automatically contact the clothes drying heat conduction rod 13 to achieve heat conduction. Clothes placed directly on the clothes drying rod 5 can simultaneously absorb the heat emitted by the heating device and the heat conducted by the heat conductor 11 to achieve a rapid drying effect. The evaporation process of the clothes can also alleviate the dryness of the indoor air.

[0060] Example 2

[0061] Based on Example 1, this embodiment adds a spray assembly 26 to the water inlet 63, as shown in the reference. Figure 14 As shown, the spray assembly 26 can directly use a wireless humidifier, such as the Jisu donut humidifier. By inserting the humidifier into the water inlet 63, the warm water in the water tank 6 can be directly sprayed out as a mist.
