Description

Technical Field

[0001] The present invention relates to the technical field of heaters, and in particular to a whole-house electric heater. Background Art

[0002] At present, there are four common methods of electric heaters: the first is to heat through a built-in electric heating device, and rely on a fan to blow out the hot air to achieve heat dissipation; the second is to use heating wires or infrared heating tubes to achieve heat radiation; the third is to heat with a built-in electric heater for natural convection heat dissipation; the fourth is to heat the thermal oil through an electric heating element, and then use a fan to convectively dissipate the heat. The first two methods can achieve rapid heating at close range, but the heating range is small and the whole house heating capacity is slightly inferior; the third method dissipates heat through natural convection, and the heating at close range is relatively slow, but the convection method can expand the heating range and achieve whole house heating; the fourth method is a product with a better overall experience. The heating effect at close range is between the first two and third methods, and it can take into account the heating of the entire environment. However, because it needs to heat the oil first and then dissipate it through the heat sink, the heating is also relatively slow, the volume and weight are large, and the heat is retained for a period of time after the power is cut off, resulting in a waste of resources. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the heater in the prior art cannot take into account both short-range and whole-house heating, thereby providing a whole-house electric heater that can take into account both short-range and whole-house heating.

[0004] In order to solve the above technical problems, the present invention provides a whole-house electric heater, comprising:

[0005] The shell has an air inlet at the bottom and an air outlet at the top;

[0006] a convection heating source mounted on the inner side of the bottom of the housing;

[0007] A radiation heating source is installed on the inner side of the upper portion of the shell, and a radiation heat outlet is provided on the side wall of the shell corresponding to the radiation heating source.

[0008] Optionally, also include:

[0009] The radiation structure is suitable for forming a radiation area with an opening toward the radiation heat opening. The radiation heating source is located in the radiation area. The radiation structure is provided with air holes.

[0010] Optionally, also include:

[0011] A reflective baffle faces the radiation heating source and covers a portion of the radiation heat outlet.

[0012] Optionally, also include:

[0013] The humidification module is arranged on the inner side of the shell and below the convection heating source.

[0014] Optionally, also include:

[0015] The guide pipe is arranged vertically, and its lower end is connected to the mist outlet of the humidification module, and its upper end is connected to the air outlet.

[0016] Optionally, also include:

[0017] A fan is fixed on the outer side wall of the shell, and the fan is suitable for blowing air into the interior of the shell.

[0018] Optionally, also include

[0019] The air duct is connected to the fan and is suitable for blowing air upward from below the convection heating source.

[0020] Optionally, the air duct is arranged horizontally and located below the convection heating source, and an air outlet is provided at the top of the air duct, and the air outlet is a strip-shaped opening arranged along the length direction of the air duct or a plurality of through holes spaced apart along the length direction of the air duct.

[0021] Optionally, when the air outlet is a plurality of through holes distributed at intervals, the areas of the through holes increase gradually in the direction away from the fan.

[0022] Optionally, it further includes: a temperature sensor, suitable for detecting the ambient temperature;

[0023] The controller is electrically connected to the temperature sensor, the convection heating source and the radiation heating source. The controller is suitable for controlling the convection heating source and / or the radiation heating source to reduce power when the temperature value fed back by the temperature sensor is greater than a preset value.

[0024] Optionally, the convection heating source is a graphene heating module.

[0025] Optionally, the radiation heating source is an infrared radiation module.

[0026] The technical solution of the present invention has the following advantages:

[0027] 1. The whole-house electric heater provided by the present invention has a convection heating source installed on the inner bottom side of the shell, and an air inlet and outlet are respectively provided at the bottom and top of the shell. When the convection heating source is in operation, the heated gas moves upward to form an airflow, which spreads throughout the house in the form of convection, achieving whole-house heating. In addition, a radiation heating source is provided on the inner upper side of the shell, and a radiation heat outlet is provided on the side wall of the shell. When the radiation heating source is in operation, the radiant heat is dissipated to the outside through the radiation heat outlet, which can achieve close-range rapid heating. When both modes are turned on at the same time, both close-range rapid heating and whole-house heating can be achieved. Alternatively, a single mode can be selected to achieve close-range rapid heating or whole-house heating, which can cater to a wider range of people and is significantly better than an electric oil heater in terms of effect, and the volume and weight are also greatly reduced.

[0028] 2. The whole-house electric heater provided by the present invention is provided with a humidification module on the inner side of the bottom of the shell. The water mist generated by the humidification module rises together with the hot air inside the shell, and in the process of rising, the small droplets are heated to evaporate into gaseous water vapor, and the gaseous water vapor can flow with the hot air. The water mist generated by the existing humidifier is composed of multiple small droplets. The water mist is a visible fog group, but because the small droplets have a certain weight, they tend to gather in a certain range after generation and cannot fully diffuse into the indoor space, resulting in a significant increase in the air humidity in the room near the humidifier, while the humidity increase in the area far from the humidifier is not obvious. The humidity distribution in the room is uneven, and it is difficult for users to experience the humidification effect. Compared with the existing humidification method, the water mist of the present invention is converted into gaseous water vapor by heating, flows with the hot air flow, and can be fully and evenly diffused into the indoor space, so that the overall humidity distribution in the room is uniformly increased, and the user experience is significantly improved.

[0029] 3. The whole-house electric heater provided by the present invention is provided with an air duct below the convection heating source, and the air duct is connected to a fan. When in use, the fan can be turned on to improve the convection efficiency, thereby improving the heating efficiency.

[0030] 4. The whole-house electric heater provided by the present invention is provided with a reflective baffle and a radiation structure. The radiant heat emitted by the radiant heating source can be reflected to the radiation structure through the reflective baffle, and then discharged from the radiant heat outlet through reflection. The irradiation angle can be adjusted, the radiation range can be increased, and the uniformity of heat radiation can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Example

[0043] Combine Figure 1-Figure 2 As shown, the whole-house electric heater provided in this embodiment includes:

[0044] The housing 1 has an air inlet 11 at its bottom and an air outlet 12 at its top. The heated gas in the housing 1 rises to form an airflow, and the air pressure inside the bottom of the housing 1 decreases. Under the action of the pressure difference, the gas is sucked into the housing 1 through the air inlet 11 and is discharged from the air outlet 12 after rising, thus forming an airflow.

[0045] A convection heating source is installed on the inner bottom side of the housing 1. The convection heating source can be a commonly used heating element such as a heating wire, a heating rod, or a graphene heating module 2. Preferably, a graphene heating module 2 is used. An air duct 5 is formed inside the graphene heating module 2 to facilitate air convection.

[0046] A radiation heating source is installed on the inner side of the upper part of the shell 1, and a radiation heat outlet 13 is provided on the side wall of the shell 1 corresponding to the radiation heating source; the convection heating source can adopt commonly used heating elements such as electric heating wires, heating rods, graphene heating modules 2, etc., and preferably adopts an infrared radiation module 3, specifically an infrared heating tube, which occupies a smaller space and has more concentrated heat; the radiation heat outlet can be a structure that dissipates heat, such as a mesh structure or a hollow sheet structure.

[0047] The whole-house electric heater provided in this embodiment can select convection mode, radiation mode, or both modes at the same time according to user needs. When both modes are turned on at the same time, the two requirements of close-range rapid heating and whole-house heating can be met, and the user experience is better.

[0048] Reference Figure 2 , as an improved structure of the above technical solution, further comprising:

[0049] The radiation structure 6 is suitable for forming a radiation zone with an opening toward the radiation heat opening, the radiation heat source is located in the radiation zone, and the radiation structure 6 is provided with an air vent 61. Preferably, the radiation structure 6 is a V-shaped radiation plate, the opening of which is toward the radiation heat opening, and the radiation heat source is located in the area surrounded by the V-shaped radiation plate. The V-shaped radiation plate is a folded plate structure with a V-shaped cross section formed by two flat plates connected at a certain angle. Of course, in other embodiments, the radiation structure 6 can also be a C-shaped radiation plate, a W-shaped radiation plate or other conventional replacement shapes. Furthermore, it also includes a reflective baffle 7, which is opposite to the radiation heat source and covers a partial area of ​​the radiation heat outlet 13; here, the reflective baffle 7 is limited to cover a partial area of ​​the radiation heat outlet 13 because the radiation heat outlet 13 still needs to leave an area for the radiation heat to be discharged.

[0050] This improved structure can collect the heat emitted by the radiation heating source and then emit it in a larger range, thereby increasing the radiation range and improving the uniformity of heat radiation.

[0051] Reference Figure 1 and Figure 3 As a further improvement of the above technical solution, it also includes:

[0052] The humidification module 8 is arranged on the inner side of the shell 1 and below the convection heating source. In specific implementation, the humidification module 8 can adopt a common humidifier structure such as an ultrasonic humidifier, an electric heating humidifier, or a pure humidifier.

[0053] In this improved structure, the water mist generated by the humidification module 8 turns into water vapor under the heating effect inside the shell 1, and diffuses into the whole house in the form of gas along with the air flow. It can be fully and evenly diffused into the indoor space, so as to achieve a uniform increase in the overall humidity distribution in the room.

[0054] Reference Figure 3 Specifically, it also includes a vertically arranged flow guide 9, with its lower end connected to the mist outlet of the humidification module 8 and its upper end connected to the air outlet 12. The water mist generated by the humidification module 8 is transported to the air outlet 12 through the flow guide 9, where it is convected with the air flow. This arrangement prevents the water mist from soaking the heating source and causing structural damage.

[0055] Reference Figure 3 and Figure 4 As an improvement to the above technical solution, the whole-house electric heater further includes:

[0056] The fan 4 is fixed on the outer wall of the housing 1 and is suitable for blowing air into the interior of the housing 1 .

[0057] The improved mechanism can speed up the gas flow by turning on the fan, thereby improving the heating efficiency.

[0058] Furthermore, the device further includes an air duct 5, which is connected to the fan 4 and is suitable for blowing air upward from the bottom of the convection heating source. The specific structure of the air duct 5 can be a horizontally arranged tube with multiple air holes at the top of the tube wall facing the bottom of the convection heating source. The fan 4 blows air into the air duct 5, and the air blows from the air holes to the convection heating component, thereby improving the convection efficiency. The air duct 5 can also be multiple vertically arranged tubes, with the upper ends of the tubes facing the bottom of the convection heating source, and the lower ends of the multiple tubes are connected and connected to the fan 4. The fan 4 blows air into the air duct 5, and the air enters the multiple tubes and then blows from their upper ends to the convection heating component.

[0059] Reference Figure 4Preferably, the air duct 5 is arranged horizontally and below the convection heating source. An air outlet is formed at the top of the air duct 5. The air outlet is a strip-shaped opening arranged along the length of the air duct or multiple through-holes spaced apart along the length of the air duct. Specifically, when the air outlet is a plurality of spaced apart through-holes, the area of ​​the through-holes increases in a direction away from the fan 4, thereby ensuring uniform air flow from different air outlets.

[0060] As a further improvement of the above technical solution, the whole-house electric heater also includes:

[0061] Temperature sensor, suitable for detecting ambient temperature; specifically, commonly used temperature sensors such as NTC, RTD or thermocouple sensors can be used;

[0062] The controller is electrically connected to the temperature sensor, the convection heating source and the radiation heating source. The controller is suitable for controlling the convection heating source and / or the radiation heating source to reduce power when the temperature value fed back by the temperature sensor is greater than a preset value.

[0063] Preferably, the ambient temperature is detected by NTC, and when the preset temperature is reached by heating, the thyristor is maintained by reducing the power, thereby achieving a constant temperature.

[0064] As a specific implementation form, the working process of the whole-house electric heater of this application is as follows:

[0065] After power is turned on, the graphene heating module 2, infrared heat radiation module, and humidification module 8 work together to achieve both whole-room heating and rapid heating at close range. When the ambient temperature detected by the NTC exceeds a preset value, the controller drives the graphene heating module 2 and infrared heat radiation module to reduce power, and the thyristor reduces power to maintain a constant temperature. Simultaneously, the power of the humidification module 8 is also reduced to prevent excessive humidification power from preventing some water mist from evaporating into water vapor, causing it to circulate as droplets, affecting the humidification range and uniformity.

[0066] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
