BRIEF DESCRIPTION OF THE DRAWINGS
The features of the invention will be more readily understood and appreciated from the following detailed description when read in conjunction with the accompanying drawings of the preferred embodiment of the present invention, in which:
Figure 1 is a drawing of a perspective view of a portable cooling and heating device.
DETAILED DESCRIPTION OF THE INVENTION
The above mentioned and other features and objects of this invention will become more apparent and better understood by reference to the following detailed description. It should be understood that the detailed description made known below is not intended to be exhaustive or limit the invention to the precise disclosed form as the invention may assume various alternative forms. On the contrary, the detailed description covers all the relevant modifications and alterations made to the present invention, unless the claims expressly state otherwise.
The present invention relates to a portable cooling and heating device that is designed for personal use. It is constructed to be lightweight and small enough to be carried around in pockets and bags. The portable cooling and heating device works by cooling at one end the device and heating at the other end of the device simultaneously. It is up to a user to choose which end of the device to use according to his or her desire to be cooled or heated based on his or her surrounding, environment, or circumstances.
We now refer to Figure 1. In a main embodiment of the present invention, the portable cooling and heating device comprises at least one Peltier element (101) that acts as the main component, at least one means of dissipating heat (102), at least two fans (103), a power supply (104), and a switch.
The Peltier element (101) further comprises a cooling side, which is able to generate a cooling effect with a temperature ranging from -50 °C to 29 °C.
In addition to the above, the Peltier element (101) further comprises a heating side, which is able to generate a heating effect with a temperature ranging from 30 °C to 100 °C.
The Peltier element (101) works by the principle of thermoelectric. When an electric current is passed through the Peltier element (101), a heat energy is produced. The heat energy is then transferred from one surface of the Peltier element (101) to another surface of the Peltier element (101), thereby resulting in a low temperature surface at one side, /.e., the cooling side, and a high temperature surface at the other side, /.e., the heating side. Due to this unique characteristic, the portable cooling and heating device of the present invention is therefore able to cool and heat simultaneously. When this Peltier element (101) is combined with other essential components and features of the present invention through a unique assembly, only then the teaching of the present invention will be attained.
In a preferred embodiment of the present invention, the Peltier element (101) comprises a TEC1 -12706 Peltier element, or the like.
As previously mentioned, there will be at least one means of dissipating heat (102). The means of dissipating heat (102) is positioned on the surface of the heating side of the Peltier element (101). It is also possible to supply and position another means of dissipating heat (102) on the surface of the cooling side of the Peltier element (101), in addition to the existing one on the heating side of the Peltier element (101). As the heat generated by the Peltier element (101) can be very high, it is crucial to ensure that the excess heat is well dissipated to the environment. Otherwise, the present device will not work as intended. Additionally, the means of dissipating heat (102) at the cooling side causes the cooling effect to be even more effective; and the means of dissipating heat (102) at the heating side ensures that the heating effect is not too extreme.
In a preferred embodiment of the present invention, the means of dissipating heat (102) comprises heat sinks.
Still referring to Figure 1 , there are at least two fans (103). One of the fans (103) is positioned on the surface of the cooling side of the Peltier element (101), and the other fan (103) is positioned on the means of dissipating heat (102) of the heating side of the Peltier element (101). In the above-described embodiment where there are two means of dissipating heat (102), one on each side of the Peltier element (101), the fan (103) of the cooling side of the Peltier element (101) is positioned on the means of dissipating heat (102) of the cooling side of the Peltier element (101), instead of being directly positioned on the surface of the cooling side of the Peltier element (101). The primary role of the fans (103) is to blow and direct the cold air of the cooling side, and the hot air of the heating side to the user, depending on which side of the present device the user desires to use. The portable cooling and heating device of the present invention is encompassed by a casing comprising a plurality of openings. In detail, the openings are situated at the positions of the means of dissipating heat. This is to ensure that the excess heat is dissipated to the environment in the most efficient manner. Also, the openings are situated at the locations of the fans, ensuring maximum output of cold air and hot air are directed to the user.
In a preferred embodiment of the present invention, the fans (103) comprise a multiple speeds setting, which can be adjusted and controlled by a controller. This allows the user to choose his or her desire fan speed. In a further preferred embodiment of the present invention, the multiple speeds setting is adjustable within the range of 60 rounds per minute to 30000 rounds per minute.
The controller is also used to adjust and control the temperature of the cooling effect, and the temperature of the heating effect. This is achieved by receiving an input of desired temperature from the user, which then the controller will employ to regulate the electric current passing through the Peltier element (101), thereby attaining the desired temperature. If the user wishes to have a lower temperature of cooling effect or a higher temperature of heating effect, the controller will allow higher electric current to pass through the Peltier element (101). On the contrary, if the user wishes to have a more moderate temperature of cooling effect that is not too low or a more moderate temperature of heating effect that is not too high, the controller will allow lower electric current to pass through the Peltier element (101).
In an embodiment of the present invention, the controller comprises a user interface for allowing the user to input the desired fan speed and temperature, thereby allowing the controller to adjust and control the multiple speeds setting of the fans (103), the temperature of the cooling side, and the temperature of the heating side.
In an embodiment of the present invention, the controller is a digital form controller.
In an embodiment of the present invention, the controller is an analogue form controller. The power supply (104) of the present invention is portable. It may comprise a battery, a power bank, a solar powered battery, a solar powered power bank, or any combination thereof. Preferably, the power supply (104) is able to deliver a power of within the range of 5 W to 1000 W.
Although the present invention has been described with reference to specific embodiments, it will be apparent for those skilled in the art that many variations and modifications can be done within the scope of the invention as described in the specification and defined in the following claims.
