Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a heater. Background Art

[0002] As an important branch of household heating equipment, skirting heaters have won the favor of consumers with their unique design and efficient heating performance in winter. Heaters not only provide people with a warm and comfortable living environment, help people resist the invasion of cold weather, but also greatly improve people's quality of life. However, with the continuous advancement of technology and consumers' increasing requirements for the performance of heating equipment, traditional skirting heaters have gradually exposed some problems and limitations.

[0003] On the one hand, traditional skirting heaters dissipate heat slowly and are not energy-efficient. Traditional skirting heaters generally use a design with multiple heating elements arranged in parallel. These heating elements have the same power, which simplifies the manufacturing process but also brings about the problem of slow heat dissipation. Because the heating elements are stacked on top of each other, the heat is greatly hindered during the transfer process, resulting in the heater being inefficient in raising the ambient temperature. This not only prolongs the time it takes to raise the indoor temperature and increases the user's waiting time, but also causes unnecessary energy waste, which does not meet the urgent needs of modern families for efficient and energy-saving heating equipment.

[0004] On the other hand, traditional baseboard heaters have some safety hazards. Since the heating element is usually heated to a high temperature when working, even exceeding 100°C, or even reaching above 200°C, there is a great safety hazard when the heating element directly dissipates heat to the outside. For users, especially children or elderly people with limited mobility, since they lack sufficient self-protection awareness or mobility, once they accidentally come into contact with the high-temperature gas output by the heater, they are likely to suffer high-temperature burns, and may even cause serious scalding accidents. In addition, long-term high-temperature operation may also cause serious consequences such as fire, posing a great threat to the safety of users' lives and property. Utility Model Content

[0005] The primary purpose of the present invention is to solve at least one of the above problems and provide a heater.

[0006] In order to meet the various purposes of the utility model, the utility model adopts the following technical solutions:

[0007] A heater is provided to meet one of the purposes of the utility model, including a control unit, a shell, and a plurality of heating components installed in the shell and controlled by the control unit. The plurality of heating components are stacked along the heat rise direction, and the control unit controls the heating components located one layer lower in the heat rise direction to operate at a higher heating power relative to the heating components located one layer higher in the heat rise direction.

[0008] Furthermore, the heat generating component of the lower layer includes a first heat generating component, and the heat generating component of the higher layer includes a second heat generating component, and the first heat generating component and at least one second heat generating component are arranged adjacent to each other up and down.

[0009] In one embodiment, in the projection direction of the horizontal plane, the projection of the first heat-generating component and the projection of the second heat-generating component are overlapped.

[0010] In a further embodiment, the first heat generating component and two second heat generating components are disposed adjacent to each other up and down, and the projections of the two second heat generating components are symmetrical about the central axis of the projection of the first heat generating component.

[0011] Specifically, in the heat rising direction, the distance between the heat generating component on the lower layer and the heat generating component on the higher side is 10-200 mm.

[0012] Specifically, the multiple heating components are arranged in parallel.

[0013] In one embodiment, a pair of support plates are provided in the housing, the heating component includes a heating rod and a plurality of heat sinks connected in series to the heating rod, and two ends of the heating rod of the heating component are respectively inserted into the pair of support plates.

[0014] Specifically, the shell includes a bottom plate, a top plate and a plurality of side plates, the bottom plate is arranged opposite to the top plate, the plurality of side plates are arranged around the bottom plate, and a plurality of ventilation holes are respectively provided on the bottom plate, the top plate and at least one side plate.

[0015] In one embodiment, the multiple side panels include a front panel and a rear panel, the front panel and the rear panel are arranged opposite to each other, and a plurality of ventilation holes are provided on the front panel and the rear panel, respectively, the front panel and the rear panel are recessed to form recessed portions corresponding to the areas where the first heating component is located.

[0016] Specifically, a plurality of supporting feet are provided on the bottom surface of the bottom plate, and an air inlet space is formed between the supporting feet and the bottom plate.

[0017] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0018] On the one hand, in the heater of the present invention, the heating component of the lower layer operates at a higher heating power than the heating component of the higher layer. The heat emitted by the heating component of the lower layer is higher than the heat emitted by the heating component of the higher layer. Due to the difference in heat, air convection is formed between the two layers of heating components, so that the heater can quickly dissipate heat to the outside and quickly increase the indoor temperature.

[0019] On the other hand, in the heater of the present invention, the heating component of the lower layer operates at a higher heating power than the heating component of the higher layer. The heat emitted by the heating component of the lower layer is higher than the heat emitted by the heating component of the higher layer. The heating component of the lower layer will transfer heat to the heating component of the higher layer, so that the temperature of the air heated by the heating component of the lower layer is reduced. The heat of the two layers of heating components merges with each other, so that the heater outputs a heat flow with an appropriate temperature to the outside, so as to avoid burning the user and preventing the occurrence of fire.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and cannot be interpreted as limiting the present invention.

[0027] Those skilled in the art will understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of ordinary technicians in the field to which the utility model belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as the meaning in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0028] The utility model provides a heater, wherein at least two of the multiple heating components of the heater have different heating powers, so that the at least two heating components generate different temperatures when working, resulting in a temperature difference, and convection is formed due to the temperature difference, thereby accelerating the efficiency of heat dissipation of the heater to the outside. Moreover, because the at least two heating components generate different temperatures when working, the heating component with a larger heating power will transfer heat to the heating component with a lower heating power, and the heat generated by the heating component with a larger heating power is balanced by the heating component with a lower heating power, so as to avoid the heater from outputting high-temperature airflow to the outside, thereby protecting the user.

[0029] In a typical embodiment of the present invention, Figure 1 and Figure 4 The heater 100 includes a control unit (not shown), a shell 120 and a plurality of heating components 130 . The plurality of heating components 130 are disposed in the shell 120 , and the control unit is electrically connected to the heating components 130 , respectively.

[0030] The plurality of heating components 130 are stacked in a heat rising direction, wherein the control unit controls the heating component located one layer lower in the heat rising direction to work at a higher heating power than the heating component 130 located one layer higher. Specifically, the heating component located one layer lower is called the first heating component 131, and the heating component located one layer higher is called the second heating component 132. The first heating component 131 and the second heating component 132 are arranged up and down in the heat rising direction, and the heating power of the first heating component 131 is greater than the heating power of the second heating component 132.

[0031] The control unit controls the operation of the heating component 130. The heating component 130 generates heat when working, and heats the surrounding air through the heat to generate hot air. The hot air radiates or flows outside the heater 100 to change the temperature of the environment outside the heater 100. Generally speaking, the heater 100 is set indoors. For the convenience of description, the environment in which the heater 100 is located is assumed to be an indoor environment, but this should not be construed as a limitation to the present invention.

[0032] Combination Figure 4 Because the heating power of the first heating component 131 is higher than that of the second heating component 132, the temperature of the hot air heated by the first heating component 131 (the hot air is called the first hot air) is greater than the temperature of the hot air heated by the second heating component 132 (the hot air is called the second hot air), so that there is a temperature difference between the first hot air and the second hot air.

[0033] The first hot air expands due to the heat and its density decreases, so it rises along the heat rising direction; and the temperature of the second hot air is lower than that of the first hot air, so that the density of the second hot air is higher than that of the first hot air, thereby forming air convection between the first hot air and the second hot air, that is to say, air convection is formed between the first heating component 131 and the second heating component 132. Due to the air convection, the first hot air and the second hot air can be accelerated to flow outside the heater 100, thereby increasing the rate of increase of indoor temperature.

[0034] The control unit controls the first heating component 131 to heat to a first temperature, and the control unit controls the second heating component 132 to heat to a second temperature, wherein the first temperature is greater than the second temperature. When the first temperature of the first heating component 131 is higher than the second temperature of the second heating component 132, heat transfer occurs between the first heating component 131 and the second heating component 132.

[0035] Heat transfer is the process of heat flowing from a hot object to a cold object. According to the second law of thermodynamics, heat always spontaneously transfers from a hotter object to a colder object until the two reach thermal equilibrium, that is, their temperatures are equal. In this process, the hot object transfers heat to the cold object through radiation, conduction or convection until the temperatures of the two become the same.

[0036] In order to quickly raise the indoor temperature, traditional heaters usually control the heating components to heat to above 100°C or even above 200°C, so as to quickly raise the indoor temperature. However, when users get close to traditional heaters, they are easily burned by the high-temperature gas output by traditional heaters, and even fires may occur.

[0037] The first temperature of the first heating component 131 of the heater 100 of the present invention is greater than the second temperature of the second heating component 132, so that the first heating component 131 and the second heating component 132 will generate heat transfer, that is, the temperature of the first hot air output by the first heating component 131 is reduced by the second heating component 132, and the temperature of the second hot air is also increased by the first hot air. It can be understood that the first hot air and the second hot air are mutually integrated to form hot air of suitable temperature, so that the user will not be burned even if he is close to the heater 100. In this embodiment, it is recommended that the first temperature of the first heating component 131 is above 100°C and the second temperature of the second heating component 132 is below 100°C, but this should not be understood as a limitation of the present invention.

[0038] In addition, multiple heating components of traditional heaters are stacked on each other to increase indoor temperature and improve efficiency more quickly. When the heater is working, since the power of each heating component is consistent, the temperature of each heating component is the same, so that convection cannot be formed between the heating components. Moreover, because multiple heating components are stacked on each other, heat is greatly hindered during the transfer process, resulting in the heater being inefficient in raising the temperature of the external environment. This not only prolongs the time it takes to raise the indoor temperature and increases the waiting time for users, but also causes unnecessary energy waste, which does not meet the urgent needs of modern families for efficient and energy-saving heating equipment.

[0039] However, in the heater 100 of the present invention, since the heating power of the first heating component 131 is different from the heating power of the second heating component 132, air convection is formed between the first heating component 131 and the second heating component 132, so that the first hot air and the second hot air can be quickly dissipated to change the indoor temperature. Although the heating power of the first heating component 131 is relatively high, the heating power of the second heating component 132 is relatively low, so that the first heating component 131 and the second heating component 132 can cooperate to output hot air at a suitable temperature. Compared with a traditional heater with multiple heating components of the same power, the heater 100 of the present invention is more energy-efficient than a traditional heater, and the indoor temperature rises quickly, so as to meet the public's demand for environmentally friendly green life.

[0040] In a typical embodiment of the utility model, the first heating component 131 and the second heating component 132 are arranged adjacent to each other in the vertical direction along the heat rising direction, so as to form a strong convection between the first heating component 131 and the second heating component 132 and facilitate heat transfer. Specifically, in the projection direction of the horizontal plane, the projection of the first heating component 131 and the projection of the second heating component 132 are arranged to overlap, so that a strong air convection can be quickly formed between the first heating component 131 and the second heating component 132, and heat transfer between the first heating component 131 and the second heating component 132 is facilitated. In this embodiment, the horizontal plane is perpendicular to the heat rising direction, and the horizontal plane is parallel to the sea level.

[0041] In a further embodiment, the heater 100 includes two second heating components 132, and the two second heating components 132 are arranged adjacent to the first heating component 131. In the projection direction of the horizontal plane, the projections of the two second heating components 132 are arranged to overlap with the projection of the first heating component 131, so that the first heating component 131 can form strong air convection between the two second heating components 132, and the first heating component 131 and the two second heating components 132 are evenly heat-transferred, thereby increasing the rate of outputting hot air outside the heater 100, so that the indoor temperature can be quickly increased. Moreover, the two second heating components 132 can cooperate with the first heating component 131 at the same time to further reduce the temperature of the first hot air generated by the first heating component 131 to avoid burning the user.

[0042] In a further embodiment, in the projection direction of the horizontal plane, the projections of the two second heating components 132 are symmetrical about the central axis of the projection of the first heating component 131, that is, the first heating component 131 generates the same heat transfer to the two second heating components 132, thereby avoiding local overheating, protecting the heater 100, and making the rate of hot air output by the heater 100 approach to consistency, thereby avoiding local rates that are too fast or too slow, and improving the user experience.

[0043] In one embodiment, in the heat rise direction, the distance between the first heat generating component 131 and the second heat generating component 132 is 10-200 mm, so that there is enough space between the first heat generating component 131 and the second heat generating component 132 to form convection. In this embodiment, in the heat rise direction, it is recommended that the distance between the first heat generating component 131 and the second heat generating component 132 is 10-100 mm.

[0044] Combination Figure 1 and Figure 2 The housing 120 includes a bottom plate 121, a top plate 122, and a plurality of side plates 123. The bottom plate 121 and the top plate 122 are arranged opposite to each other along the heat rising direction. The plurality of side plates 123 are arranged around the bottom plate 121. The bottom plate 121, the top plate 122, and the plurality of side plates 123 are arranged to form a closed structure of the housing 120. In this embodiment, a plurality of ventilation holes 126 are respectively provided on the bottom plate 121, the top plate 122, and at least one side plate 123, so that the plurality of heating components 130 can output hot air to the outside through the plurality of ventilation holes 126 to increase the indoor temperature.

[0045] A plurality of supporting legs 127 are also provided on the bottom surface of the bottom plate 121, and the housing 120 is supported by the plurality of supporting legs 127, so that a gap (the gap is referred to as an air inlet space) is formed between the bottom plate 121 and the ground or work surface. Since hot air rises along the heat rising direction, when the first heating component 131 is working, after entering the air inlet space, the external air enters the area where the first heating component 131 and / or the second heating component 132 are located through the ventilation holes 126 on the bottom plate 121 along the heat rising direction, so as to increase the rate of heating air of the first heating component 131 and the second heating component 132, and increase the rate of outputting the hot air heated by the first heating component 131 and the second heating component 132 to the outside.

[0046] In one embodiment, the plurality of side panels 123 include a front panel 124 and a rear panel 125, the front panel 124 and the rear panel 125 are arranged parallel to the axis of the heating component 130, and the front panel 124 and the rear panel 125 are arranged front to back oppositely. Since the first heating component 131 and the two second heating components 132 are arranged adjacent to each other up and down along the heat rising direction, the space occupied by the first heating component 131 is smaller than the space occupied by the two heating components 130 together, the front panel 124 is concave toward the first heating component 131 to form a concave portion (the concave portion is referred to as the first concave portion 1241), and the rear panel 125 is concave toward the second heating component 132 to form a concave portion (the concave portion is referred to as the second concave portion 1251).

[0047] A plurality of ventilation holes 126 are provided on the first recessed portion 1241 and the second recessed portion 1251 to shorten the distance between the first heating component 131 and the external air in the front-to-back direction, so that the external air can quickly enter the position of the first heating component 131, so that the first heating component 131 heats the external air and accelerates the output of the first hot air of the first heating component 131 to the outside.

[0048] In one embodiment, in combination Figure 4 , the heating component 130 includes a heating rod 133 and a plurality of heat sinks 134, and the plurality of heat sinks 134 are connected in series to the heating rod 133. When the heating rod 133 is powered on, the heating rod 133 generates heat, and the heat on the heating rod 133 is transferred to the plurality of heat sinks 134, so as to quickly dissipate the heat through the plurality of heat sinks 134. In this embodiment, the heating component 130 is provided with two heating rods 133, and the two heating rods 133 are arranged in parallel, and the plurality of heat sinks 134 are simultaneously passed through the two heating rods 133, so as to quickly increase the indoor temperature through the two heating rods 133. In this embodiment, the structures of the heating components 130 of the heater 100 are the same. In one embodiment, the heat sink 134 is made of copper metal material or aluminum metal material.

[0049] Combination Figure 3 and Figure 4 A pair of support plates 128 are further disposed in the housing 120. The pair of support plates 128 are disposed at two ends of the axial direction of the heating rod 133. The two ends of the heating rod 133 are respectively inserted into the pair of support plates 128 to support the heating component 130. In this embodiment, the plurality of heating components 130 share the pair of support plates 128.

[0050] In one embodiment, the multiple heating components 130 are arranged in parallel, and the parallel arrangement of multiple heating components 130 can significantly improve the heating efficiency of the heater 100. Each heating component 130 works independently, and multiple heating components 130 generate heat at the same time and quickly dissipate the heat to the surrounding environment, which can maximize the use of electrical energy and reduce the loss of heat during the transfer process, thereby quickly increasing the indoor temperature. In addition, due to the parallel arrangement, the working number of the heating components 130 can also be adjusted according to actual needs, realizing flexible power adjustment to meet the heating needs in different scenarios.

[0051] In one embodiment, in combination Figure 3 The heater 100 is further provided with a control box 140, the control unit is arranged in the control box 140, a power supply is further provided in the control box 140, the power supply is electrically connected to the control unit, and the power supply supplies power to the plurality of heating components 130. The power supply is further provided with a power supply line 141, the power supply line 141 is led out to the outside through the control box 140 and the housing 120, so as to be connected to an external power supply.

[0052] To sum up, the heating power of the first heating component of the heater of the present invention is higher than the heating power of the second heating component. The first heating component and the second heating component cooperate with each other to simultaneously form air convection and heat transfer, so that the heater can quickly output hot air of suitable temperature outside the heater to increase the indoor temperature.
