Abstract
Description
Technical Field
[0001] This utility model relates to the field of charcoal water boiler technology, and in particular to a dust-free electric charcoal water boiler for boiling water and making tea. Background Technology
[0002] Charcoal-fired tea stoves are popular among tea lovers and outdoor enthusiasts. Traditional charcoal-fired tea stoves are mostly made of red clay, which has the following problems: 1. The stove is heavy and difficult to carry; the open burner causes ash to fall everywhere during combustion, which is unsanitary. 2. Because it is made of red clay, the stove may crack after prolonged use, affecting its lifespan. 3. It is slow to ignite initially, sometimes requiring manual ventilation; the fire intensity is also difficult to control during combustion; due to the lack of a combustion aid, the charcoal may not burn completely, producing smoke and resulting in low thermal efficiency. 4. The stove gets extremely hot when boiling water, so it cannot be placed on wooden tables or other heat-sensitive surfaces, and the entire stove should not be touched to avoid burns. Utility Model Content
[0003] The purpose of this invention is to provide a dust-free electric charcoal tea stove. When it is working and burning, the charcoal ash will not be discharged to the outside, but will only fall inside the stove body, ensuring a clean and hygienic environment. Through the heat dissipation device, the temperature of the outer layer of the stove body is greatly reduced.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0005] A dust-free electric charcoal tea stove includes a stove body, a stove core, a diversion air duct assembly, a heat insulation lining, a dust baffle plate, a stove top cover plate, a power supply, a printed circuit board, and a control panel.
[0006] The furnace body is made of metal and is a cylindrical body (shell) with an opening at the top and an inner cavity in the middle; the furnace core, dust baffle, heat insulation lining, and diversion air duct assembly are located inside the inner cavity of the furnace body;
[0007] The furnace core is open at the top, has a combustion chamber in the middle, has several air outlets along its top edge, and has an air inlet at its bottom.
[0008] The furnace core is also equipped with a horizontally arranged grate, and a strip-shaped cavity is provided in the middle of the grate. An electric heating tube is horizontally arranged in the strip-shaped cavity, and one end of the electric heating tube passes through the installation through hole of the furnace core, furnace body and heat insulation lining.
[0009] The diversion air duct assembly includes a blower, a main air duct, a combustion air duct, and a heat dissipation vent. The main air duct is a conduit with a cavity in the middle, with an air inlet at one end and an air outlet at the other end; the air inlet is connected to the blower; one end of the combustion air duct is inserted into the air outlet, and the other end is located at the bottom of the furnace core and communicates with the air inlet; a heat dissipation vent is also provided between the air outlet and the outer wall of the combustion air duct. The airflow blown by the blower is divided into two parts: one part enters the furnace core through the combustion air duct to aid combustion, and the other part enters the area between the furnace body and the heat insulation lining through the heat dissipation vent to dissipate heat and cool the furnace body (outer wall of the furnace body).
[0010] The heat insulation lining is a cylindrical body with openings at both the top and bottom and a cavity in the middle; the heat insulation lining is located between the furnace body and the furnace core, with an inner heat insulation cavity between it and the furnace core and an outer heat dissipation cavity between it and the furnace body.
[0011] The furnace top cover is located on the top surface of the furnace body, furnace core, and heat insulation lining. A teapot heating port is provided in the middle of the cover, and several strip-shaped heat dissipation holes are provided on the outer edge of the teapot heating port.
[0012] The dust baffle is a ring-shaped piece with openings at both ends and a cavity in the middle. It is located between the furnace core and the heat insulation lining, and its top is fixed to the bottom of the furnace top cover. The air outlet is connected to the inner heat insulation cavity. When the hot air flow and dust from the burning charcoal are blocked by the teapot heating port, the hot air flow mixed with dust flows from the air outlet to the inner heat insulation cavity. After the dust baffle turns the hot air flow (causing it to flow downward) and slows down, the dust in the hot air flow will fall to the bottom of the furnace body under the downward push of gravity and air flow. The hot air flow will flow out of the furnace body through the strip-shaped heat dissipation holes of the furnace top cover.
[0013] The furnace body has a base at its bottom, and the base has an inner cavity with an ash collection hopper inside. Ash inlets are provided on the base between the furnace core and the bottom of the heat-insulating inner lining.
[0014] The combustion chamber, air outlet, internal heat insulation chamber, ash inlet, and ash collection hopper are connected in sequence.
[0015] The base has a return port in the middle, so that the hot air can enter the combustion chamber from the bottom of the furnace core after circulating around.
[0016] The power supply, control panel, blower, and printed circuit board are electrically connected; the control panel is equipped with several adjustment buttons (or knobs).
[0017] Preferably, it also includes a housing, which is located on the outside of the furnace body, and the printed circuit board and control panel are fixed on the housing.
[0018] Briefly describe its working principle:
[0019] The blower blows air into the main air duct, and the airflow enters the combustion chamber of the furnace core through the combustion air duct to aid combustion; the airflow flowing out from the heat dissipation air vent enters the outer heat insulation chamber, absorbs the heat from the furnace body and the heat insulation lining, and then is discharged from the strip heat dissipation holes on the furnace top cover plate to keep the outer wall of the furnace at a safe temperature.
[0020] Meanwhile, the cavity between the furnace body and the heat insulation lining also reduces heat conduction to a certain extent, preventing the furnace body from reaching high temperatures.
[0021] This application has the following characteristics:
[0022] The stove body is made of metal, which is much lighter and stronger than a mud stove, making it easy to carry and durable.
[0023] It has a built-in power supply and blower. The blower delivers air to increase oxygen and aid combustion, resulting in more complete combustion and saving fuel. The fire intensity can be controlled by adjusting the airflow. It also shortens the initial ignition time.
[0024] When boiling water, the blower sends air into the main air duct. Part of the air in the main air duct is sent to the combustion chamber through the combustion air duct to aid combustion, and part is sent into the outer heat dissipation chamber through the heat dissipation vent. This dissipates the heat radiating from the furnace core upwards and outwards. This not only prevents heat from being conducted to the lower part of the furnace body, ensuring the safety of the electrical components inside, but also significantly reduces the temperature of the outer layer of the furnace body, especially the lower part inside and outside of the furnace body. It is kept at a normal temperature for a long time, so it can be touched and moved by hand without burning people. It can also be placed on wooden tables or other places that are not resistant to high temperatures, thus improving the safety factor.
[0025] The kettle features a large, flat heating spout with a flat inner edge and three concentric rings of strip-shaped ventilation holes along its outer and middle edges. A dust baffle and an insulating lining surround the furnace core. When boiling water, the flat-bottomed kettle is placed on the heating spout, ensuring a tight seal between the kettle, the spout, and the ventilation holes. This prevents the exhaust gas and ash from being directly discharged from the heating spout and ventilation holes. Instead, the gas flows from the furnace core's outlet to the dust baffle and insulating lining. The ash is slowed by the dust baffle and insulating lining, causing it to fall below the lining. Because the exhaust gas is lighter, it continues upward through the insulating lining and exits through the ventilation holes at the heating spout. This design effectively discharges only exhaust gas, not ash.
[0026] The beneficial effects of this utility model are:
[0027] When it is burning, the ash will not be discharged outside, but will only fall inside the furnace, ensuring a clean and hygienic environment.
[0028] The drawer-type charcoal ash collection box makes cleaning charcoal ash easy, convenient, and hygienic.
[0029] Its overall design is lightweight and sturdy, making it easy to carry and extending its service life.
[0030] It is easy to use, starts up quickly, boils water quickly, and has a high thermal efficiency in charcoal combustion, thus saving fuel.
[0031] The heat dissipation device ensures the safety of electrical components inside the furnace and significantly reduces the temperature of the outer layer of the furnace, keeping the lower part of the furnace at a constant temperature so that it will not burn your hands when touched, thus improving the safety factor.
