Abstract
The utility model relates to an inner circulation air duct structure of an indoor heater, which mainly consists of a scroll casing, a centrifugal fan, an air inlet, an air outlet and an electrical heating block. The centrifugal fan is arranged in the middle of the scroll casing; the electrical heating block is positioned at least at two symmetric air outlets which are arranged uniformly or in an air exhausting channel corresponding with the air outlet around the scroll casing; four air exhausting channels which are communicated with the corresponding air outlets are arranged around the scroll casing; the electrical heating blocks which consist of PTC heating components are positioned at the positions of the four outlets; the front side of the scroll casing is provided with a panel component and is respectively equipped with ventilation openings and air outlets; thus the convection type inner circulation is formed in the scroll casing; at least four sides of the panel component on the front side of the scroll casing; at least four air outlets are arranged on the front side of the scroll casing; and each air outlet corresponds with a PTC heating component which is positioned at the air outlet. The utility model has the advantages of simple structure, convenient and reliable operation, energy conservation, uniform air supply, good operating effect, high thermal efficiency, provision of more comfort for people and the like.
Description
Technical field
The utility model relates to a kind of interior circulation air path structure that is exclusively used in household heater, belong to the ventilation technical field of heating.
Background technology
At present, the technology of bathroom heating device is quite ripe, can see bathroom heating device product that be made up of different structure, all size and model on market; On the Chinese patent communique, also can inquire a lot of similarly bathroom heating device patented technologies.Along with the quickening of bathroom heating device model change trend, the multi-functional bathroom warmer that single bathroom heating device will be integrated heating, take a breath, throw light on substitutes, and the efficient of warmer is more and more higher, and the effect of heating is become better and better; But because the heating of warmer product be unable to do without exothermal infrared and the electrical heating heating, therefore, on the basis of at present existing mature structure, to further improve heating efficiency, obtain result of use better, more comfortable some difficulty that seems, its main cause is to be difficult on the structure to break through the circle of the existing mature technology of existing bathroom heating device.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, and is easy to use, reliable, can realize the interior circulation air path structure of the household heater of circulation in four sides air-out and the convection type.
The purpose of this utility model is finished by following technical solution, it is mainly by spiral case, centrifugal blower, inlet and outlet, compositions such as electrical heating piece, centrifugal fan is installed in the middle of the described spiral case, in air outlet place that at least two symmetries around it are uniform or the air-out passage electrical heating piece is installed corresponding to air outlet.
Be equipped with four around the described spiral case and be communicated with the air-out passage of air outlet separately, and the electrical heating piece that the PTC heater element constitutes is installed at four air outlet places.
Described spiral case front is equipped with panel assembly, and the spiral case front is respectively arranged with ventilating opening and air outlet, and forms in the convection type in spiral case and circulate.
Described spiral case front panel assembly is provided with four sides air-out mouth at least, and every air outlet is to there being a PTC heater element that is installed in the air outlet place.
The utility model belongs to a kind of improvement to prior art, and it has simple in structure, and is easy to use, reliable, energy-conservation, and air-supply is even, and result of use is good, thermal efficiency height, and people use characteristics such as more comfortable.
Description of drawings
Fig. 1 is a side structure schematic diagram of the present utility model.
Fig. 2 is a Facad structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 1,2, the utility model is mainly by spiral case 3, centrifugal blower, inlet and outlet, electrical heating piece 4 compositions such as grade, in the middle of the described spiral case 3 centrifugal fan is installed, it is made of motor 1 and wind wheel 2, and the symmetrical at least all around of spiral case 3 is evenly equipped with two air outlets by the air-out passage, in described air outlet place or the air-out passage 6 corresponding to air outlet electrical heating piece 4 is installed.
Be equipped with four around the spiral case 3 shown in the accompanying drawing and be communicated with the air-out passage 6 of air outlet separately, and the electrical heating piece 4 that the PTC heater element constitutes is installed at four air outlet places; The air outlet air-out that the wind that described centrifugal fan produced is provided with by spiral case 3 four sides so that produce heat under the situation of equilibrium blowing, has avoided the heat transition to concentrate cause uneven in temperature.
Spiral case described in the utility model 3 fronts are equipped with panel assembly 5, and spiral case 3 fronts are respectively arranged with ventilating opening and air outlet, and form in the convection type in spiral case 3 and circulate.Described spiral case 3 front panel assemblies 5 are provided with four sides air-out mouth at least, and every air outlet is to there being a PTC heater element that is installed in the air outlet place.
The utility model is a kind of improvement to prior art, and therefore except the said structure content, other technology contents of not addressing is known technology, and those skilled in the art is understanding on the basis of the present utility model and can implement easily.
