Description

Technical Field

[0001] This invention relates to the field of gas heaters, and particularly to vertical heaters. Background Technology

[0002] A vertical gas heater ignites the combustion grille of the gas-fired burner, and the heated air inside the heater flows outwards, dispersing to the outside and raising the ambient temperature. Currently, because heated air is less dense and rises, existing vertical gas heaters typically have a reflector at the top. This reflector changes the direction of the hot air flow and reflects far-infrared radiation from the combustion grille to the outside. However, because the reflector and combustion grille at the top of the vertical gas heater need to be exposed, it occupies a significant amount of space in the vertical direction, which is inconvenient for transportation and storage. Summary of the Invention

[0003] The purpose of this invention is to provide a vertical heater to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0005] A standing heater, comprising:

[0006] The base includes an upper part and a lower part that are connected vertically;

[0007] A burner, which is located at the top of the upper part;

[0008] A reflector is disposed on top of the burner;

[0009] The base has a top-open gas cylinder receiving cavity;

[0010] The connection between the base and the base includes a first connection state and a second connection state. In the first connection state, the lower part is detachably connected to the top of the base. In the second connection state, the base, the burner, and the reflector are inverted and inserted into the gas tank receiving cavity.

[0011] The beneficial effects of this invention are as follows: When the vertical heater is in normal use, the base and the base are connected in a first connection state, with the lower part of the base connected to the top of the base, so that the base supports the base, and the burner and reflector on the top of the base work normally; when the vertical heater needs to be transported or stored, the base and the base are connected in a second connection state, that is, the lower part of the base is detached from the top of the base, and then the base, burner, and reflector are inverted and inserted into the gas cylinder receiving cavity of the base, so that the exposed burner and reflector are stored in the gas cylinder receiving cavity of the base, thereby reducing the space occupied by the vertical heater in the height direction, which is beneficial to the transportation and storage of the vertical heater.

[0012] As a further improvement to the above technical solution, the base is provided with a through-hole, and the outer side wall of the base is provided with a step. In the first connection state, the top of the base is inserted into the through-hole, and the bottom end of the lower part abuts against the step.

[0013] When the base and the base are in the first connection state, the receiving hole at the bottom of the base fits onto the top of the base, and the lower end abuts against the step on the outer side wall of the base, making the connection between the base and the base more convenient and making it easier to switch the base and the base from the second connection state to the first connection state.

[0014] As a further improvement to the above technical solution, the vertical heater also includes:

[0015] A hinged frame, which is connected to the lower part;

[0016] A hinged base is hinged to the hinge frame, and the hinged base rotates about a horizontal axis relative to the hinge frame. In the first connection state, the hinged base is detachably connected to the base.

[0017] When the base and the base are in the first connection state, the lower part is detachably connected to the base via the hinge bracket and the hinge seat. Rotate the base along the horizontal axis to expose the gas cylinder receiving cavity of the base, so that the user can put the gas cylinder into the gas cylinder receiving cavity. Then the user connects the gas cylinder to the burner on the base. Finally, rotate the base to close the top of the gas cylinder receiving cavity.

[0018] As a further improvement to the above technical solution, the vertical heater also includes:

[0019] A housing, which is disposed in the receiving hole and divides the receiving hole into upper and lower sides;

[0020] An air supply assembly is located on the upper side of the housing.

[0021] The housing divides the receiving hole into upper and lower sides. When the base and the base are in the first connection state, the gas supply component on the upper side of the housing is connected to the gas tank in the gas tank receiving cavity of the base, and the gas supply component provides the gas source for the burner. When the base and the base are in the second connection state, since the base is upside down, the housing closes the receiving hole. The housing, the receiving hole, and the gas tank receiving cavity form a protective space, and the burner, reflector, and gas supply component are all set in the protective space, reducing damage to the burner, reflector, and gas supply component during the transportation or storage of the vertical heater.

[0022] As a further improvement to the above technical solution, the burner includes:

[0023] A drainage tube, which is connected to the top of the upper part, the top of the drainage tube being open;

[0024] A combustion net is provided around the outer periphery of the diversion tube;

[0025] A top cover, which is placed on top of the combustion net;

[0026] An ejector tube is connected to the bottom of the drainage tube.

[0027] After the gas ejected from the ejector tube is blocked by the top cover, it diffuses outward from the top of the diversion tube to the combustion net, so that the gas can be ignited on the combustion net. The top cover blocks the gas ejected from the ejector tube to prevent the gas flow rate from being too fast and to ensure that the gas is fully burned.

[0028] As a further improvement to the above technical solution, the burner also includes a flow baffle, which is connected to the top of the top cover, extends into the flow guide tube, has an open bottom, and the inlet of the ejector tube extends into the flow baffle.

[0029] The gas ejected from the ejector tube flows upward into the baffle shroud. After being obstructed by the baffle shroud, the gas flows downward and towards the space between the inner wall of the ejector tube and the outer wall of the baffle shroud. Then, the gas flows upward along the inner wall of the ejector tube towards the top cover. Finally, after being blocked by the top cover, the gas diffuses outward to the combustion mesh. Thus, a tortuous airflow channel is formed between the ejector tube, the baffle shroud, the ejector tube, and the top cover, which slows down the gas flow rate ejected from the ejector tube, allowing the gas to mix fully with the air, ensuring complete combustion of the gas, and improving the heating efficiency of the gas.

[0030] As a further improvement to the above technical solution, the top of the drainage tube has a tapered hole that is smaller at the top and larger at the bottom.

[0031] When the gas flows upward from the inner wall of the diversion tube and the outer wall of the baffle, the gas converges through the conical hole and then impacts the bottom wall of the top cover, which helps the top cover to diffuse the gas and prevents the gas from escaping directly to the outside from the top of the diversion tube.

[0032] As a further improvement to the above technical solution, the vertical heater also includes a support rod, the upper and lower ends of which are respectively connected to the bottom of the reflector and the top of the upper part.

[0033] Because there are a first connection state and a second connection state between the base and the pedestal; in the first connection state, the support rod supports the bottom of the reflector and the top of the upper part of the base, improving the structural strength of the reflector and the burner, and preventing the reflector from pressing the burner for a long time and causing the burner to deform; in the second connection state, since the reflector, the burner and the base are upside down, the support rod connects the reflector and the base, preventing the reflector from pulling the burner for a long time and causing the burner to deform.

[0034] As a further improvement to the above technical solution, the reflector includes:

[0035] Top cover;

[0036] The lower cover is connected to the bottom of the upper cover, and a heat dissipation cavity is formed between the lower cover and the upper cover;

[0037] The middle cover is disposed in the heat dissipation cavity and is connected to the upper cover, forming a heat insulation cavity between the middle cover and the upper cover.

[0038] A heat dissipation cavity is formed between the top and bottom covers, and a heat insulation cavity is formed between the middle cover and the top cover. This helps to reduce the temperature of the top cover and prevent users from accidentally touching the top cover and getting burned.

[0039] As a further improvement to the above technical solution, the top of the upper part is tapered, with a smaller top and a larger bottom. In the second connection state, the outer side wall of the upper part abuts against the top of the gas tank receiving cavity.

[0040] In the second connection state, the reflector, burner, and base are inverted and inserted into the gas tank receiving cavity of the base. The upper outer wall abuts against the top of the gas tank receiving cavity, preventing the inverted base from pressing on the reflector and burner. Attached Figure Description

[0065] There are four support rods 260, which are distributed circumferentially along the through hole of the bottom cover. The four support rods 260 support the top cover 230 and the bottom cover, thereby increasing the structural strength of the bottom cover, the diversion tube 210, the combustion net 220, and the top cover 230, and preventing the burner 200 from being deformed by pressure.

The upper and lower ends of the support column 340 are respectively inserted into the upper and lower central holes. The lower end of the support column 340 abuts against the lower cover 320. The outer side wall of the support column 340 is provided with external threads. A nut is fitted on the upper and lower ends of the support column 340. The upper cover 310 and the middle cover 330 are located between the two nuts. The support column 340 fixes the relative position of the middle cover 330 and the upper cover 310.
