The indoor temperature rise time is prolonged, the waiting time of a user is prolonged, unnecessary energy waste is caused, and the urgent requirements of modern families on efficient and energy-saving heating equipment are not met. And a plurality of heating elements of arranging side by side will lead to heat to concentrate in inside the room heater for the shell of room heater is overheated, when the user contacts the shell, scalds the user.

On the other hand, the traditional skirting line type warmer has some potential safety hazards. Because the heating body is usually heated to a higher temperature even exceeding 100 ℃ and even reaching more than 200 ℃ during operation, the heating body has great potential safety hazard when directly radiating outside. For users, especially children or elderly people with inconvenient movements, because of the lack of enough self-protection consciousness or mobility, once the users carelessly contact with the high-temperature gas output by the warmer, the users are easily suffered from high-temperature burn, and even serious scalding accidents can be caused. In addition, the long-time high-temperature operation can cause serious consequences such as fire disaster and the like, and the life and property safety of users is greatly threatened.

And because the at least two heating components generate different temperatures during working, the heating component with larger heating power can transfer heat to the heating component with lower heating power, and the heating component with lower heating power balances the heat generated by the heating component with larger heating power, so that the warmer is prevented from outputting high-temperature airflow to the outside, and the user is protected.

In an exemplary embodiment of the present utility model, referring to fig. 1 and 4, the heater 100 includes a control unit (not shown), a housing 110, and a plurality of heat generating components 130, wherein the plurality of heat generating components 130 are disposed in the housing 110, and the control unit is electrically connected to the heat generating components 130, respectively.

The control unit controls the operation of the heating element 130, the heating element 130 will generate heat when operated, the ambient air is heated by the heat to generate hot air, the hot air is dispersed or flowed out of the heater 100 to change the temperature of the environment outside the heater 100, and generally, the heater 100 is disposed in a room, and the environment where the heater 100 is disposed is an indoor environment for convenience of description, but should not be construed as limiting the utility model.

The plurality of heat generating components 130 are stacked in the heat rising direction and divided into a plurality of layers, each layer being provided with one or more heat generating components 130. In this embodiment, a first layer and a second layer are provided, and the second layer is disposed on an upper side of the first layer, that is, the first layer and the second layer are disposed up and down along the heat rising direction.

In this embodiment, referring to fig. 4, a first heating element 131 and a third heating element 133 are disposed in the first layer, a second heating element 132 is disposed in the second layer, and under the control of the control unit, the heating power of the first heating element 131 is respectively greater than the heating power of the second heating element 132 and the heating power of the third heating element 133, and it can be understood that, in operation, the heat generated by the first heating element 131 is respectively greater than the heat generated by the second heating element 132 and the heat generated by the third heating element 133.

Because the heating power of the first heating element 131 is higher than that of the second heating element 132, the temperature of the hot air (referred to as the first hot air) heated by the first heating element 131 is higher than that of the hot air (referred to as the second hot air) heated by the second heating element 132, so that a temperature difference exists between the first hot air and the second hot air.

The first heating component 131 and the second heating component 132 are arranged up and down, the first hot air is heated and expanded to reduce the density, so that the first hot air rises along the rising direction, and the second hot air is lower in temperature than the first hot air, so that the second hot air is higher in density than the first hot air, and air convection is formed between the first hot air and the second hot air, that is, air convection is formed between the first heating component 131 and the second heating component 132, and the first hot air and the second hot air can flow out of the heater 100 in an accelerating way due to the air convection, so that the rising rate of the indoor temperature is improved.

The first heat generating component 131 and the second heat generating component 132 are arranged vertically adjacent to each other along the heat rising direction, so that strong convection is formed between the first heat generating component 131 and the second heat generating component 132 and heat transfer is facilitated. In particular, in the projection direction of the horizontal plane, the projection of the first heat generating component 131 and the projection of the second heat generating component 132 are overlapped or overlapped, so that strong air convection can be quickly formed between the first heat generating component 131 and the second heat generating component 132, and heat transfer between the first heat generating component 131 and the second heat generating component 132 is facilitated. In this embodiment, the horizontal plane is perpendicular to the direction of the heat rise, and the horizontal plane is parallel to the sea level.

In one embodiment, the distance between the first heat generating component 131 and the second heat generating component 132 in the heat rising direction is 10-200mm so that there is a sufficient distance between the first heat generating component 131 and the second heat generating component 132 to form convection. In the present embodiment, the distance between the first heat generating component 131 and the second heat generating component 132 in the heat rising direction is recommended to be 10-100mm.

In one embodiment, in the heat rising direction, the third heat generating component 133 and the second heat generating component 132 are disposed up and down along the heat rising direction, and the heat generating power of the third heat generating component 133 is the same as or similar to the heat generating power of the second heat generating component 132, so as to prevent the second heat generating component 132 from blocking the third heat generating component 133 from outputting hot air to the outside, and in the projection direction of the horizontal plane, the projection of the third heat generating component 133 is not intersected with the projection of the second heat generating component 132, so as to prevent the second heat generating component 132 from blocking the third heat generating component 133 from outputting hot air to the outside.

In this embodiment, the first heat generating component 131 and the third heat generating component 133 are disposed in the same layer, the first heat generating component 131 and the third heat generating component 133 are disposed adjacent to each other, and the heat generating power of the first heat generating component 131 is greater than the heat generating power of the third heat generating component 133.

Because the heating power of the first heating element 131 is higher than that of the third heating element 133, the temperature of the first hot air heated by the first heating element 131 is higher than that of the hot air heated by the third heating element 133 (referred to as third hot air), so that there is a temperature difference between the first hot air and the third hot air.

The first hot air is heated and expanded to reduce the density, the temperature of the third hot air is lower than that of the first hot air, the density of the third hot air is higher than that of the first hot air, and the third hot air with higher density diffuses to the first hot air with lower density, so that air convection is formed between the first hot air and the third hot air, that is, air convection is formed between the first heating component 131 and the third heating component 133, and the first hot air and the third hot air can accelerate to flow out of the warmer 100 due to air convection, so that the lifting rate of the indoor temperature is improved.

In this embodiment, the first heating element 131 and the third heating element 133 are disposed side by side on the same layer, and the first heating element 131 and the third heating element 133 are disposed adjacently, so that strong convection is formed between the first heating element 131 and the third heating element 133 and heat transfer is facilitated.

In one embodiment, the distance between the first heat generating component 131 and the third heat generating component 133 is 10-200mm in the arrangement direction between the plurality of heat generating components 130 of the first layer so that there is a sufficient space between the first heat generating component 131 and the third heat generating component 133 to form convection. In the present embodiment, in the arrangement direction, it is recommended that the distance between the first heat generating component 131 and the third heat generating component 133 is 10 to 100mm.

Therefore, the air convection between the first hot air and the second hot air and the air convection between the first hot air and the third hot air are mutually overlapped, so that the air convection inside the warmer 100 is further improved, and the heat generated by the first heating component 131, the second heating component 132 and the third heating component 133 can be rapidly dispersed outside the warmer 100, so that the indoor temperature is rapidly improved.

A plurality of heating elements of traditional room heater pile up each other and set up to the indoor temperature of promotion efficiency of faster. When the warmer works, the power of each heating component is consistent, so that the temperatures of the heating components are the same, and convection cannot be formed among the heating components. And, because a plurality of heating element stacks up the setting each other, the heat has received great hindrance at the transmission in-process, leads to the room heater inefficiency when promoting external environment temperature. The indoor temperature rise time is prolonged, the waiting time of a user is prolonged, unnecessary energy waste is caused, and the urgent requirements of modern families on efficient and energy-saving heating equipment are not met.

In the warmer 100 of the present utility model, the heating power of the first heating element 131 is different from the heating power of the second heating element 132 and the heating power of the third heating element 133, so that air convection is formed between the first heating element 131 and the second heating element 132 and between the first heating element 131 and the third heating element 133, respectively, so that the first hot air, the second hot air and the third hot air can be rapidly dispersed, and the indoor temperature is changed, so that the warmer 100 of the present utility model is more power-saving than the conventional warmer, and the indoor temperature is rapidly raised, and the demands of the public for environment-friendly and green life are satisfied.

Heat transfer is the process of heat flowing from a high temperature object to a low temperature object. According to the second law of thermodynamics, heat is always spontaneously transferred from a higher temperature object to a lower temperature object until the two reach thermal equilibrium, i.e. their temperatures are equal. In this process, the high temperature object transfers heat to the low temperature object by radiation, conduction or convection until the temperatures of the two tend to be consistent.

The control unit controls the first heating component 131 to heat to a first temperature, the control unit controls the second heating component 132 to heat to a second temperature, the control unit controls the third heating component 133 to heat to a third temperature, and the first temperature is respectively greater than the second temperature and the third temperature. When the heater 100 is operated, the first heat generating component 131 generates heat transfer with the second heat generating component 132 and the third heat generating component 133 due to the fact that the first temperature is higher than the second temperature and the third temperature, respectively.

In order to quickly raise the indoor temperature, the conventional heater generally controls a plurality of heating components to heat to above 100 ℃ and even above 200 ℃ so as to quickly raise the indoor temperature. However, when a user approaches the conventional warmer, the user is easily burned by the high-temperature gas output from the conventional warmer, and even a fire is easily caused.

The first temperature of the first heating component 131 of the warmer 100 of the present utility model is greater than the second temperature of the second heating component 132 and the third temperature of the third heating component 133, respectively, so that heat transfer occurs between the first heating component 131 and the second heating component 132 and the third heating component 133, respectively, 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 third heating component 133, and the temperature of the second hot air and the third hot air is also increased by the first hot air, so that it can be understood that the first hot air, the second hot air and the third hot air are mutually fused to form hot air with proper temperature, so that a user cannot be burned even if the user approaches the warmer 100.

Although the heating power of the first heating element 131 is higher, the heating power of the second heating element 132 and the third heating element 133 is lower, so that the first heating element 131, the second heating element 132 and the third heating element 133 cooperate to output hot air with a proper temperature. Compared with a plurality of heating components with the same power of the traditional warmer, the warmer 100 of the utility model saves electricity compared with the traditional warmer, has fast indoor temperature rise, and meets the requirements of the public on environment-friendly and green life.

In the present embodiment, it is recommended that the first temperature of the first heat generating component 131 is above 100 ℃, the second temperature of the second heat generating component 132 is below 100 ℃, and the third temperature of the third heat generating component 133 is below 100 ℃, but this should not be construed as limiting the present utility model.

In this embodiment, the bottom plate 111, the top plate 112, and at least one side plate 113 are respectively provided with a plurality of ventilation holes 114, so that the plurality of heat generating components 130 can output hot air to the outside through the plurality of ventilation holes 114, thereby increasing the indoor temperature.

The bottom surface of the bottom plate 111 is further provided with a plurality of supporting feet 115, and the housing 110 is supported by the plurality of supporting feet 115, so that a gap (referred to as an air inlet space) is formed between the bottom plate 111 and the ground or the working surface. Because the hot air rises along the rising direction, when the first heating component 131 works, the external air enters the air inlet space, and then enters the areas where the first heating component 131 and the third heating component 133 are located through the ventilation holes 114 on the bottom plate 111 along the rising direction, so as to increase the rate of heating the air by the first heating component 131 and the third heating component 133, and increase the rate of outputting the hot air formed by heating the first heating component 131 and the third heating component 133.

In one embodiment, referring to fig. 4, the heat generating component 130 includes a heat generating rod 134 and a plurality of heat dissipating fins 135, and the plurality of heat dissipating fins 135 are connected to the heat generating rod 134 in series. When the heat bar 134 is energized, the heat bar 134 generates heat, and the heat on the heat bar 134 is transferred to the plurality of heat sinks 135 to rapidly dissipate the heat through the plurality of heat sinks 135. In this embodiment, the heat generating component 130 is provided with two heat generating rods 134, the two heat generating rods 134 are arranged in parallel, and the plurality of heat dissipating fins 135 simultaneously penetrate through the two heat generating rods 134, so as to rapidly raise the indoor temperature through the two heat generating rods 134. In this embodiment, the heat generating components 130 of the heater 100 have the same structure. In one embodiment, the heat sink 135 is made of a copper metal material or an aluminum metal material.

In the present embodiment, the plurality of heat generating components 130 share the pair of support plates 116.

In one embodiment, the plurality of heat generating components 130 are arranged in parallel, and the plurality of heat generating components 130 are arranged in parallel, so that the heating efficiency of the heater 100 can be significantly improved. Each heating component 130 works independently, and the plurality of heating components 130 generate heat at the same time and rapidly emit the heat to the surrounding environment, so that the electric energy can be utilized to the maximum extent, the loss of the heat in the transmission process is reduced, and the indoor temperature is rapidly increased. In addition, due to the parallel connection, the working quantity of the heating components 130 can be adjusted according to actual needs, so that flexible power adjustment is realized, and heating requirements under different scenes are met.

In one embodiment, referring to fig. 3, the heater 100 is further provided with a control box 141, the control unit is disposed in the control box 141, and a power source is further disposed in the control box 141, and is electrically connected to the control unit, and the power source supplies power to the plurality of heating components 130.
