Description

Technical Field

[0001] This utility model relates to the technical field of household heating equipment, and in particular to an anti-tipping oil-filled radiator. Background Technology

[0002] An oil-filled radiator is a type of space heater, generally consisting of an oil-filled body, heat-conducting oil, heating elements, temperature control elements, and a power supply. The oil-filled body has a connected oil cavity filled with highly heat-conducting oil, and the heating elements are immersed in the oil. When powered on, the oil heated by the heating elements flows through the inner cavity of the radiator due to the gravity difference caused by the density difference, transferring the acquired heat to all parts of the radiator. Through heat conduction from the radiator shell and natural convection of the surrounding air, the space is heated.

[0003] The heating element of an oil-filled radiator is usually located at the bottom of the radiator body and is immersed in heat-conducting oil. During use and storage, the radiator body must be kept vertical to avoid the heating element being exposed to the heat-conducting oil, which could lead to overheating and explosion.

[0004] The current solution involves installing a tilt switch or infrared sensor on the side of the oil-filled radiator to detect whether it is tilting. When tilting is detected, an alarm is triggered and the heating element is shut off to avoid risks. However, sensors are prone to false alarms, affecting normal use. Moreover, although this method can cut off the power in time after the oil-filled radiator tilts, the plate structure of the radiator still poses a risk of tipping, affecting the user experience. In addition, since the oil-filled radiator can only be placed upright, its height results in a large space occupation, making it very inconvenient for home storage. Utility Model Content

[0040] 1. Control switch. Detailed Implementation

[0041] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0042] like Figure 1-7 As shown in the following embodiments, an anti-tipping oil heater is disclosed.

[0043] Example 1

[0044] An anti-tipping oil heater includes,

[0045] A control module includes a control switch 1 disposed on the housing 100, and a temperature controller and circuit board located inside the housing 100.

[0046] A heat dissipation module includes a plurality of heat sink units arranged sequentially along a first direction, and a heat dissipation channel is provided between the plurality of heat sink units;

[0047] A base module is located at the bottom of the control module and the heating module to support the control module and the heating module and keep them above the ground;

[0048] The base module includes a front base 110 and at least one rear base 300. The front base 110 is located at the bottom of the housing 100 of the control module and supports the control module. The rear base 300 is located at the bottom of the heat sink unit and supports the heat sink unit.

[0049] The rear base 300 is configured as an anti-tipping base.

[0050] The above is the basic scheme of this embodiment.

[0051] The heat sink unit includes two plates that are in close contact with each other, and a heat dissipation channel is provided between the two plates. The heat transfer oil flows in the heat dissipation channel to transfer heat. The plates absorb the heat of the heat transfer oil and dissipate it into the air, thereby heating the external space.

[0052] The heat dissipation channels between adjacent heat sink units are connected, and heating tubes are provided to heat the heat transfer oil. The usage method is the same as that of existing electric oil heaters, so it will not be described in detail here.

[0053] The control module is equipped with a control switch 1, which supplies power to the heating element through the circuit board inside the housing 100, causing the heating element to heat up. At the same time, the control module is equipped with a temperature controller to detect the temperature of the heat sink unit and feed it back to the circuit board, so that the circuit board can adjust the heating level of the heating element.

[0054] Preferably, in this embodiment, the first direction is along the length of the oil heater.

[0055] The instability of oil-filled radiators lies in the fact that the heat sink unit occupies most of the space in the radiator, and the outer periphery of the heat sink unit is a heat source. During use, it is easy to come into contact with the high temperature of the heat sink unit, which can cause burns. At the same time, if the oil-filled radiator is accidentally knocked over during use, the heat sink unit on the radiator can also come into contact with the human body, resulting in burns.

[0056] Therefore, when using an oil-filled radiator, in addition to the consumer's own control over the contact between the radiators, it is also necessary to ensure the stability of the radiator's placement so that it will not easily tip over with minor touches.

[0057] In this embodiment, a base module is provided to provide stable support for the oil-filled radiator. The front base 110 supports the control module, and the rear base 300 supports the heating module. In order to ensure the support strength, in this embodiment, the front base 110 can be integrally formed at the bottom of the housing 100 of the control module, or it can be fixed to the bottom of the housing 100 by connection. The rear base 300 is set at the bottom of the heating module, preferably at the bottom of the heat sink unit furthest from the control module. In addition to providing stable support for the heat sink unit, it also makes the lower end of the heating module higher than the ground, avoiding direct contact between the heat source and the ground, thus preventing damage to the ground.

[0058] Preferably, in this embodiment, the rear base 300 is configured as an anti-tipping base, which can at least ensure that the position of the heating module will not easily tip over when a collision occurs, thereby ensuring the stability of the entire oil heater.

[0059] Specifically, the rear base 300 has a trapezoidal cross-sectional profile in the second direction, and has a first support point 310 and a second support point 320 on the same horizontal line, as well as a third support point 330 and a fourth support point 340 on the same horizontal line.

[0060] The horizontal distance between the first support point 310 and the second support point 320 is less than the horizontal distance between the third support point 330 and the fourth support point 340.

[0061] Reference Figure 2 As shown, the first support point 310 and the second support point 320 are located above the third support point 330 and the fourth support point 340, and the horizontal distance between the first support point 310 and the second support point 320 is smaller than the horizontal distance between the third support point 330 and the fourth support point 340, so that the four support points form a trapezoidal outline when connected.

[0062] Compared to other quadrilaterals, trapezoids have better stability, thus providing good stability support for the heating module.

[0063] Preferably, in this embodiment, the second direction is the width direction of the oil heater, which is perpendicular to the first direction.

[0064] In order for the rear base 300 to connect and support the heat sink unit, in this embodiment, the upper end surface of the rear base 300 is provided with a U-shaped groove and a plate groove 301 is provided, and the lower end of the heat sink unit is disposed in the plate groove 301.

[0065] Reference Figure 3 As shown, the U-shaped groove is set between the first support point 310 and the second support point 320, and the plate groove 301 is opened along the U-shaped path of the U-shaped groove. At the same time, the structure of the U-shaped groove matches the lower end shape of the heat sink unit, so that the outer edge of the lower end of the heat sink unit can be inserted into the plate groove 301 for fixation.

[0066] It should be noted that the two ends of the slot 301 extend to the upper surface of the rear base 300. When the heat sink unit is installed in the U-shaped slot, the first support point 310 and the second support point 320 located at both ends of the U-shaped slot are located on both sides of the heat sink unit, and preferably on both sides of the heat sink unit in the vertical direction. That is, the upper part of the rear base 300 holds the lower part of the heat sink unit tightly in place.

[0067] In this embodiment, in order to ensure the center of gravity position of the rear base 300 and further ensure the stability of the rear base 300, a recess is provided on the lower end surface of the rear base 300, and a counterweight structure 350 is provided in the recess.

[0068] Reference Figure 3 As shown, the recess is located on the lower end face of the rear base 300 and corresponds to the position of the U-shaped groove. Preferably, the opening at the lower end of the recess is smaller than the opening at the upper end of the U-shaped groove, thereby ensuring that the cross-sections of the third support point 330 and the fourth support point 340 are larger than the cross-sections of the first support point 310 and the second support point 320, thus ensuring the support strength and stability of the trapezoidal structure.

[0069] A counterweight structure 350 is provided in the recess to increase the weight of the lower part of the rear base 300, thereby lowering the center of gravity of the rear base 300 and further ensuring the stability of the rear base 300.

[0070] Preferably, in this embodiment, the counterweight structure 350 is an extension plate 351 and a counterweight plate 352 arranged perpendicularly to the extension plate 351.

[0071] Reference Figure 3As shown, in order to reduce the weight of the rear base 300 and lower its center of gravity as much as possible, the extension plate 351 in this embodiment is a thin plate in the vertical direction, while the counterweight plate 352 is a thin plate in the horizontal direction.

[0072] Preferably, to further lower the center of gravity of the rear base 300, the two side edges of the rear base 300 in the second direction are set as symmetrical arcs.

[0073] Reference Figure 3 As shown, the connecting surfaces of the first support point 310 and the third support point 330, as well as the connecting surfaces of the second support point 320 and the fourth support point 340, are set as arc-shaped surfaces, and the arc curvature of the upper part is less than that of the lower part, so that the weight is concentrated in the lower part of the rear base 300.

[0074] Example 2

[0075] This embodiment is an improvement upon Embodiment 1, the purpose of which is to increase the stability of the rear base 300, thereby ensuring the anti-tipping function of the oil-filled heater. The specific implementation method is as follows:

[0076] An anti-tipping bracket 400 is provided on the rear base 300. The anti-tipping bracket 400 is located on the third support point 330 and the fourth support point 340 of the rear base 300, and provides stable support for the third support point 330 and the fourth support point 340.

[0077] In this embodiment, there are two anti-tipping brackets 400, which support the third support point 330 and the fourth support point 340 on the rear base 300 respectively, thereby ensuring the stability of the third support point 330 and the fourth support point 340.

[0078] Specifically, the anti-tipping bracket 400 includes an annular ring, one side of which is configured as a rotating arm 410 and passes through the rear base 300; the side opposite to the rotating arm 410 is a support arm 420, which can rotate to the outside of the rear base 300 to support the ground.

[0079] Reference Figure 4 As shown, in this embodiment, the anti-tipping bracket 400 is configured as a quadrilateral annular ring, with one side extending through and connecting to the rear base 300, forming a rotating arm 410; the side opposite the rotating arm 410 is a support arm 420; when the anti-tipping bracket 400 rotates around the rotating arm 410 to the supported state, the support arm 420 contacts the ground, forming support. When the support arm 420 is in the supported position, it is located outside the third support point 330 or the fourth support point 340.

[0080] Preferably, in this embodiment, the anti-tipping bracket 400 is configured as a trapezoidal ring structure, and the length of the rotating arm 410 is less than the length of the support arm 420.

[0081] Specific reference Figure 7 As shown, the two side arms 430 connecting the support arm 420 and the rotating arm 410 are set to an inclined state. In the supported state, the length of the upper rotating arm 410 is greater than the length of the lower support arm 420, so that the anti-tipping bracket 400 supports the third support point 330 or the fourth support point 340. Compared with square or rectangular supports, the trapezoidal support has greater strength and better stability.

[0082] Furthermore, the anti-tipping bracket 400 is formed by bending a cylindrical strip, and the support arm 420 forms a line contact with the ground. In order to increase the friction between the support arm 420 and the ground, in this embodiment, the support arm 420 is provided with an anti-slip sleeve 440.

[0083] Specific reference Figure 5 As shown, in this embodiment, an anti-slip sleeve 440 is provided on the support arm 420, and the lower end face of the anti-slip sleeve 440, that is, the end face in contact with the ground, is set as a plane, thereby increasing the contact area between the anti-slip sleeve 440 and the ground, increasing the friction, and ensuring the anti-slip performance of the anti-tipping bracket 400.

[0084] Preferably, in this embodiment, the anti-slip sleeve 440 is made of rubber, and anti-slip texture can be provided on the bottom.

[0085] Preferably, in this embodiment, one end of the bottom of the anti-slip sleeve 440 is configured with an arc-shaped transition and is located on the side close to the rear base 300, as shown in the following figure. Figure 6 As shown, when the anti-tipping bracket 400 is rotated to the support position, the end of the anti-slip sleeve 440 slides against the ground first through the arc surface, which reduces the resistance during rotation compared to sliding directly through the tip.

[0086] When moving the oil heater, the anti-tipping bracket 400 needs to be retracted so that the support arm 420 is detached from the ground. In this embodiment, a damping ring 450 is fitted on the rotating arm 410.

[0087] Specific reference Figure 5 As shown, in this embodiment, the diameter of the rotating arm 410 is smaller than the inner diameter of the through hole on the rear base 300. A damping ring 450 is fitted on the rotating arm 410. When the anti-tipping bracket 400 is rotated, damping is formed between the rotating arm 410 and the inner wall of the through hole, so that the support arm 420 can stop at any position and thus detach from the ground.

[0088] Preferably, in this embodiment, the damping ring 450 is a rubber sleeve.

[0089] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
