Technical Field

The invention relates to the field of living appliances, in particular to a warmer.

Background

The electric oil heater is a common household heating appliance, and the working principle is that an electric heating device heats heating oil in the heater body, and after the temperature of the heating oil and the heating plate is increased, the heating oil and air are subjected to heat exchange to achieve the purposes of environmental temperature rise and heating for users.

The internal temperature of the heater sheets on the existing electric oil heater is high, the edge temperature is low, the heater sheets are in a row and are arranged in parallel, wherein adjacent heater sheets are connected through oil pockets arranged at the upper end and the lower end of the heater sheets, and the oil pockets are communicated with oil guide grooves on the heater sheets. The heater sheets arranged in a row can lead heat to be concentrated between the heater sheets and be difficult to spread, so that the heating effect is poor, and the heating efficiency can not be fully exerted. In addition, the arrangement of the upper and lower oil pockets also impedes air convection, so that the air convection rate becomes smaller, and the heat exchange rate becomes lower. Most oil-filled heaters increase heating effect by increasing power in order to increase heating effect, which results in waste of electricity.

Disclosure of Invention

Therefore, the invention aims to overcome the defects that heat is concentrated between the heater sheets and is difficult to be emitted due to unreasonable arrangement mode of the heater sheets in the prior art, thereby providing the heater with good heat dissipation effect and low energy consumption.

In order to solve the technical problems, the warmer comprises a plurality of cooling fins, wherein the cooling fins are connected in series only through the middle parts of the cooling fins, and the cooling fins after being connected in series are at least divided into two rows.

The radiating fins are divided into two rows and are arranged in an X shape.

The cooling fins in the first row and the cooling fins in the second row are arranged at intervals.

The included angle a of the X-shaped is 40-50 degrees.

The included angle a is 45 degrees.

The heat radiating fin comprises a heat radiating fin body, an oil pocket arranged at the middle part of the heat radiating fin body, and an oil guide groove arranged in the heat radiating fin body and communicated with the oil pocket, wherein two adjacent heat radiating fins are connected in series in a butt joint mode of the oil pocket and the oil pocket.

The oil pocket is disposed at the center of the fin body.

The warmer is an electric heating oil heater.

The technical scheme of the invention has the following advantages:

1. in the invention, the radiating fins of the warmer are connected in series only through the middle parts of the radiating fins, so compared with the warmer with the existing radiating fins connected in series at the end parts of both ends, the serial parts are reduced, the obstruction of the serial parts to air convection is reduced, the radiating fins after being connected in series are at least divided into two rows, thus the area of the radiating fins and the air convection is increased, the heat in the middle high-temperature area of the radiating fins can be better utilized, the heating effect is increased, and the oil heater can achieve the effect of heating by using a low-power heating body, and the electric quantity waste is reduced.

2. In the invention, the radiating fins are divided into two rows and are arranged in an X shape. The warmer with the structure has the advantages of high heat exchange rate, good heating effect, small occupied space and easy manufacture. In addition, the radiating fins are arranged in an X shape, so that the contact area between the radiating fins and the ground is increased, the radiating fins are more stable to mount, a user can use the warmer without installing casters, and the trouble of installing the casters is eliminated.

Detailed Description

The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.

Example 1

As shown in fig. 1-3, the warmer of the present invention includes a plurality of cooling fins 4, wherein the cooling fins 4 are connected in series only through the middle part of the cooling fins 4, and the cooling fins 4 after being connected in series are arranged in at least two rows.

Because the radiating fins 4 are connected in series only through the middle parts of the radiating fins 4, compared with the radiating fins 4 connected in series at the end parts of the two ends in the prior art, the number of the connecting parts is reduced, so that the obstruction of the connecting parts to air convection is reduced, the radiating fins 4 connected in series are at least divided into two rows, the area of the radiating fins and the area of the air convection are increased, the heat in a high-temperature area in the middle of the radiating fins can be better utilized, the heating effect is improved, and the oil heater can achieve the heating effect of a high-power heater by using a low-power heater, and reduces the electric quantity waste.

The radiating fins 4 are divided into two rows and are arranged in an X shape. The heat sinks 4 may be arranged in three or four rows, and the number of rows may be set as needed. In this embodiment, the heat sink is preferably divided into two rows and arranged in an "X" shape. The warmer with the structure has the advantages of high heat exchange rate, good heating effect, small occupied space and easy manufacture. In addition, the radiating fins 4 are arranged in an X shape, so that the contact area between the radiating fins 4 and the ground is increased, the radiating fins 4 are placed more stably, a user can use the warmer without installing casters, and the trouble of installing casters is avoided.

Further, the heat sink 4 in the first row and the heat sink 4 in the second row are spaced from each other. Therefore, the space between two adjacent cooling fins 4 in each row of cooling fins 4 is increased, so that the heat exchange rate of the warmer is higher, and the warming effect is better.

As shown in FIG. 2, in the specific arrangement, the included angle a of the X-shaped is 40-50 degrees.

In this embodiment, the angle a is preferably 45 °. By the angle, the area increment of the radiating fins 4 is large, and the stability of the radiator body formed by serially connecting the radiating fins 4 is good.
