Description

Technical Field

[0001] The present application relates to a heating device and a heating device kit. Background Art

[0002] The prior art includes portable heating devices such as cassette stoves or photovoltaic stoves, which can be used outdoors to heat food, for example. However, since cassette stoves use liquefied gas tanks to heat with an open flame, there may be certain safety risks. For example, in the event of improper operation or leakage of the liquefied gas tank, the cassette stove may explode, causing serious personal injury and property damage. In addition, the use of open flames for heating may also cause a fire due to improper use. Photovoltaic stoves generally rely on solar panels to convert light energy into electrical energy, and then use the obtained electrical energy for heating. Due to the limited photoelectric conversion efficiency, the actual heating power of the photovoltaic stove may be low, and the use of the photovoltaic stove is strongly affected by weather conditions. It may be difficult to meet the use requirements on cloudy days, overcast days or at night.

[0028] The present application will be described below with reference to the accompanying drawings, which illustrate several embodiments of the present application. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and to fully illustrate the scope of protection of the present application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments.

[0029] It should be understood that the terms used in this specification are intended only to describe specific embodiments and are not intended to limit this application.

[0033] Figure 1A perspective view of a heating device 1 according to one embodiment of the present application is schematically shown. The heating device 1 can be used as a portable heating device. Specifically, a portable heating device in the present application can be understood as a heating device that can be used without being connected (for example, via a pipeline) to a fixed energy source such as a natural gas grid or a household power grid. For example, the heating device 1 can be used as a kitchen appliance, for example, outdoors or in a restaurant, for keeping food warm, heating, or cooking. In addition, the heating device 1 can also have other diverse usage scenarios. For example, the heating device 1 can be used in a laboratory for water bath heating or sterilizing laboratory equipment.

[0034] The heating device 1 may include a heating device 2, a base 3, and a rechargeable battery pack 4 separate from the heating device 2 and the base 3. The heating device 2 and the base 3 may be passive, and the heating device 1 may be powered by the rechargeable battery pack 4 separate from the heating device 2 and the base 3.

[0035] like Figure 3 As shown, the heating device 2 may include a container 21 and a heating assembly 20, wherein the heating assembly 20 is configured to at least partially heat the container 21. The container 21 may be configured in the form of a kettle, a frying pan, a soup pot, a crucible, etc., depending on the use requirements. Figure 3 In the embodiment, the container 21 is exemplarily configured in the form of a soup pot and has two lugs 212 extending radially outward from the container body 211. A heat-insulating grip (not shown) may be provided on the lugs 212, which may be gripped by a user's hand to move the heating device 2.

[0036] The heating component 20 can be configured as an electric heating component, especially a DC heating component, which can generate heat by the principles of resistance heating, induction heating, arc heating, electron beam heating, infrared heating or dielectric heating. Here, the heating component 20 can be configured as a heating wire, a heating tube, a heating plate, a carbon fiber heating film, an enamel heating film, a graphene heating film, etc. Figure 3 As shown, the heating assembly 20 can be disposed in the lower portion 22 of the heating device 2 and configured as a heating plate that rests against the bottom region of the container 21. Alternatively, in some embodiments, the heating assembly 20 itself can form the bottom region of the container 21 and thus exist as a part of the container 21. The heating assembly 20 can be constructed integrally with the container 21. In other embodiments, the heating assembly 20 and the container 21 can be configured to be detachable or separable.

[0037] The lower portion 22 of the heating device 2 may have a flat bottom surface 221 , so that the heating device 2 can be placed on, for example, a table or the ground with the flat bottom surface without tipping over.

[0038] In order to power the heating device 1 , in particular the heating assembly 20 , via the rechargeable battery pack 4 , the base 3 may comprise a first electrical connection 31 (see Figure 2 ), the rechargeable battery pack 4 may include a second electrical interface 41 (see Figure 1 and Figure 7 In addition, the heating device 1 may include a power supply cable (not shown), via which the first electrical interface 31 and the second electrical interface 41 can be electrically connected to each other. Thus, electrical energy can be supplied from the rechargeable battery pack 4 to the base 3 via the power supply cable. In some embodiments, the power supply cable can exist independently of the rechargeable battery pack 4 and the base 3, such that the power supply cable can be plugged into or unplugged from the corresponding first electrical interface 31 or second electrical interface 41. In other embodiments, the power supply cable can remain connected to one of the first electrical interface 31 and the second electrical interface 41, such that the power supply cable can be an integral component of the base 3 or the rechargeable battery pack 4. The power supply cable can have a suitable length, for example, 1 to 3 meters, such as 1.8 meters. The relative positions of the base 3 and the rechargeable battery pack 4 can be flexibly selected during use. For example, in some usage scenarios, the base 3 can be located on a tabletop, while the rechargeable battery pack 4 can be placed below the tabletop.

[0039] In addition, in order to provide electrical energy to the heating device 2, the heating device 2 can be detachably electrically coupled to the base 3 via a coupler. The coupler may include a first coupling member (not shown) provided on the heating device 2 and a second coupling member 32 (see FIG. Figure 4 ). By placing the heating device 2 on the base 3, the first coupling member of the heating device 2 and the second coupling member 31 of the base 3 can be conveniently electrically coupled, thereby achieving electrical coupling between the heating device 2 and the base 3. The design in which the heating device 2 and the base 3 can be separated from each other facilitates cleaning and, if necessary, replacement of the heating device 2. In some embodiments, the coupler may include two pairs of electrical contacts connected in parallel. The electrical contacts may be configured as silver contacts. As a result, the coupler can stably and reliably transmit high current and high power, which is particularly advantageous for heating components with high current or high power requirements.

[0040] like Figure 4 As shown, the base 3 may include a recess 34, and the second coupling member 32 may be arranged in the recess 34. The shape of the recess 34 may correspond to the shape of the lower part 22 of the heating device 2, and the first coupling member may be arranged in the lower part 22 of the heating device 2, in particular in the area of ​​the bottom surface 221 (see Figure 3The position of the first coupling member in the lower portion 22 of the heating device 2 can correspond to the position of the second coupling member 32 in the recess 34 of the base 3, so that the heating device 2 can be securely mounted on the base 3 with its lower portion 22 accommodated in the recess 34 of the base 3 and at the same time establish an electrical connection between the first coupling member and the second coupling member 32. Figure 5 As shown, an anti-slip pad 35, here four anti-slip pads 35, can be provided at the bottom of the base 3. Here, each anti-slip pad 35 is arranged at a distance from each other along the circumferential direction.

[0041] See also Figure 1 、 Figure 4 and Figure 5 The base 3 may include an operation panel 33. The operation panel 33 may be, for example, disposed on a side wall of the base 3 and radially opposite to the first electrical interface 31 of the base 3. The operation panel 33 may be configured as a human-machine interaction device, for example, to display the working gear of the heating device 1 to the user and to allow the user to adjust the working gear of the heating device 1. Specifically, in some embodiments, such as Figure 6 As shown, the operating panel 33 may include a digital tube assembly 331 for displaying the working gear. The light-emitting element 337 of the digital tube assembly 331, such as an LED element, may be arranged on the circuit board 333 of the base 3. The operating panel 33 may include a light guide bracket 335 for guiding the light emitted by the light-emitting element 337 to the operating surface 334. Here, an input device for adjusting the working gear, such as a button 332, may be provided on both sides of the digital tube assembly 331. The button 332 may be configured as a spring button. The light guide bracket 335 may include a hole 336 corresponding to the spring button. Alternatively, the button 332 may also be configured as an infrared sensor button or a membrane button, etc. In other embodiments, the operating panel 33 may also be configured as a display screen, in particular a touch display screen, for displaying and adjusting the working gear of the heating device 1.

[0042] The circuit board 333 can constitute the controller of the heating device 1, or the circuit board 333 can be connected to another controller, which is configured to adjust the working gear of the heating device 1 according to the operation of the button 332, for example, adjusting the output power of the rechargeable battery pack 4 and / or the heating power of the heating component 20.

[0043] In some embodiments, the heating device 1, in particular the heating device 2, may include a temperature sensor and / or a pressure sensor. The temperature sensor may, for example, be arranged near the heating component 20 of the heating device 2 and / or on the first coupling member of the heating device 2. The pressure sensor may, for example, be arranged in the container 21 of the heating device 2 in order to measure the pressure in the container 21. The controller can be connected to the temperature sensor and / or pressure sensor signal via a coupler between the heating device 2 and the base 3. The controller can be configured to adjust the output power of the rechargeable battery pack 4 or the heating power of the heating component 20 according to the sensor signal of the temperature sensor and / or pressure sensor. Thus, on the one hand, the heating temperature of the heating device 1 can be controlled in a targeted manner to achieve different functions. On the other hand, dry burning can be prevented, thereby improving the safety of use of the heating device 1.

[0044] In some embodiments, the heating device 1 may include a heat recovery device. The heat recovery device may be configured to charge the rechargeable battery pack 4 by recovering dissipated heat energy during use of the heating device 1. To this end, the heat recovery device may be provided in the heating device 2, for example, near the heating assembly 20. Alternatively, the heat recovery device may also be provided in the base 3, for example, in an area of ​​the base 3 near the heating assembly 20 of the heating device 2. The heat recovery device may, for example, convert the temperature difference into voltage through the thermoelectric effect, and the generated voltage may be used to charge the rechargeable battery pack 4 or directly used to power the heating device 1. In some embodiments, the heat recovery device may, for example, include thermoelectric semiconductors and / or thermocouples. As a result, the energy utilization rate of the heating device 1 can be advantageously improved, and the endurance of the heating device 1 can be increased.

[0045] In some embodiments, the heating apparatus may include a thermal insulation device disposed within the base 3 and / or the heating device 2. The thermal insulation device may be implemented, for example, as an insulating pad, vacuum insulation layer, reflective insulation layer, or the like made of insulating material. Specifically, the lower portion 22 of the heating device 2, for example, the area of ​​the heating assembly 20 facing away from the container 21, may be filled with insulating materials such as ceramic fiber, mineral wool, or calcium silicate board. Alternatively or additionally, the base 3 may be filled with insulating material surrounding the recess 34. This can further improve the heating efficiency of the heating apparatus 1.

[0046] In some embodiments, the first electrical interface 31 of the base 3 may also be configured to be connected to an external power source so as to provide power via the external power source as an alternative to the rechargeable battery pack 4. The external power source is typically a relatively immobile, fixed power source, such as a vehicle electrical system or a household electrical system.

[0047] In some embodiments, as Figure 8Most clearly, the rechargeable battery pack 4 can include a housing 42 and a lithium battery pack 40 located therein. Lithium batteries have the advantages of high energy density, low self-discharge rate, no memory effect, light weight, high charging efficiency, long service life, and environmental friendliness. Advantageously, the rechargeable battery pack 4 can include six lithium battery packs connected in parallel, each of which can include six lithium battery cells connected in parallel. In some embodiments, the rechargeable battery pack 4 can have a power of 400W to 1000W, particularly 480W to 800W. This is particularly suitable for the heating device 1's intended use as a kitchen appliance.

[0048] In some embodiments, the first electrical interface 31 and the second electrical interface 41 can be interfaces suitable for transmitting high currents, such as XT60 interfaces. To ensure safe use of the heating device 1, the first electrical interface 31 and the second electrical interface 41 can both be female connectors. Accordingly, male connectors can be provided at both ends of the power supply cable.

[0049] In some embodiments, the rechargeable battery pack 4 may include a charging interface for charging the rechargeable battery pack. Advantageously, the second electrical interface 41 may additionally function as the charging interface, allowing the rechargeable battery pack 4 to be charged and discharged via the second electrical interface 41. To charge the rechargeable battery pack 4 via the second electrical interface 41, the heating device 1 may include a charging cable. Unlike a power supply cable, the charging cable may have a connector corresponding to the second electrical interface 41 at one end and a connector for connecting to, for example, a household electrical network at the other end.

[0050] In some embodiments, as Figure 7 As can be seen most clearly, the rechargeable battery pack 4 may include at least one third electrical interface 43, which may be configured to charge a mobile device, such as a mobile phone, camera, wireless headset, tablet computer, laptop computer, etc. The third electrical interface 43 may be configured, for example, as a USB interface, a Micro USB interface, or a Type-C interface. Figure 7 In the embodiment, the rechargeable battery pack 4 may include, for example, two USB interfaces and one Type-C interface.

[0051] Continue to refer to Figure 7 The rechargeable battery pack 4 may include a display device 44, which may be configured to display the battery pack's power level. Furthermore, the display device 44 may also be configured to display the battery pack's operating status, such as a power-on state, a low-power state, and the like. Specifically, the display device 44 may include a display screen, a digital tube, and / or an LED light-emitting element. Figure 7In the embodiment, the display device 44 may include a display screen 441 for displaying the power level of the battery pack and a lamp bead 442, such as an LED light emitting element, for indicating the operating status of the battery pack.

[0052] like Figure 8 As shown, the second electrical interface 41, the third electrical interface 43, and the display device 44 can be located on or electrically connected to the circuit board 49. The circuit board 49 can be connected to a battery protection board, particularly a lithium battery protection board, which can implement functions such as overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, temperature protection, balancing, and status detection for the battery. Alternatively, the circuit board 49 itself can include a battery protection circuit, particularly a lithium battery protection circuit.

[0053] exist Figure 7 In the embodiment, the rechargeable battery pack 4 has a rectangular parallelepiped housing 42. The second electrical interface 41, the third electrical interface 43, and the display device 44 of the rechargeable battery pack 4 can all be provided on the same (first) side surface 45 of the housing 42, which facilitates intuitive operation of the rechargeable battery pack 4 by the user. Furthermore, an on / off button 46 for the rechargeable battery pack 4 can also be provided on the first side surface 45 of the housing 42.

[0054] A second side surface 47 of the housing 42, perpendicular to the first side surface 45, may be provided with a recess 48 suitable for inserting a user's fingers. The user can, for example, insert four fingers other than the thumb, particularly the tips and pads of the fingers, into the recess 48 to conveniently move, for example, carry, the rechargeable battery pack 4. Advantageously, the recess 48 may be provided on both opposing side surfaces of the housing 42.

[0055] like Figure 8 As shown, the housing 42 may be composed of an upper housing portion 421 and a bottom plate 422. The upper housing portion 421 may form the four side surfaces and a top surface of the rectangular parallelepiped housing 42, while the bottom surface of the rectangular parallelepiped housing 42 is formed by the bottom plate 422. The upper housing portion 421 and the bottom plate 422 may be connected to each other, for example, via screws, and together define an interior space of the housing 42 relative to the surrounding environment. The lithium battery pack 40 may be accommodated in this interior space.

[0056] Figure 9 and Figure 10 The bottom plate 422 is shown separately and may include strips 424 rising from the bottom surface 423 of the bottom plate 422. The strips 424 extend parallel to the short sides of the bottom plate 422 and are arranged in two rows along the long sides of the bottom plate 422. Figure 9 and Figure 10 For the sake of clarity, only some of the strips 424 are provided with reference numerals. Figure 10As seen in the cross-sectional view of FIG, each slat 424 together with the bottom surface 423 of the bottom plate 422 can have a substantially Z-shaped cross section, so that a channel 425 communicating with the surrounding environment can be formed between two adjacent slats 67. The channel 425 can be used, for example, to dissipate heat or to drain liquid that has undesirably entered the housing 42. Here, each slat 424 can be oriented with respect to the center line M (see FIG. 4 ) of the bottom plate 422 in the longitudinal direction. Figure 9 , the center line M extends parallel to the short side of the bottom plate 422) is constructed in a mirror-symmetrical manner, that is, the individual slats 424 located on one side of the center line M can be mirror-symmetrical to the individual slats 424 located on the other side of the center line M.

[0057] like Figure 9 As shown, a holding structure 426 for the circuit board 49 may be formed on the base plate 422. The holding structure 426 may be configured as two holding plates extending upward from the bottom surface 423 of the base plate 422. The two holding plates may be spaced apart from each other and may each have a corresponding recess 427, into which the circuit board 49 may be inserted and thereby held on the base plate 422.

[0058] The heating device 1 according to the present application does not require a pipeline connection to the natural gas grid or the household power grid, but instead advantageously uses a rechargeable battery pack 4 as an energy source, thereby having good portability, environmental friendliness, flexibility in use, and safety in use. In addition, the heating device 1 according to the present application operates in an electric heating mode, does not require the use of an open flame, and is not affected by weather conditions. It can stably and reliably perform the heating function even in rainy or windy weather. Therefore, the heating device 1 according to the present application is also particularly suitable for use in outdoor environments. Furthermore, in the heating device 1 according to the present application, the independent heating device 2, base 3, and rechargeable battery pack 4 can be carried and stored separately, thereby advantageously improving the portability and flexibility of the heating device 1. Since the electrical connection between the base 3 and the rechargeable battery pack 4 is achieved through a power supply cable, during the use of the heating device 1, the rechargeable battery pack 4 can be placed relatively far away from the heat source, thereby improving the overall safety of the heating device 1.

[0059] The present application also relates to a heating device kit, which may include the aforementioned heating device 1 and at least one additional heating appliance. The at least one additional heating appliance may, for example, comprise a container 21 of a different type or form than the heating appliance 2 of the heating device 1 shown in the accompanying drawings. For example, the container of the at least one additional heating appliance may be configured as a kettle or a pan. The at least one additional heating appliance may be used on a base 3 as an alternative to the heating appliance 2 shown in the accompanying drawings.

[0060] The exemplary embodiments of the present application have been described above with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and modifications may be made to the exemplary embodiments of the present application without departing from the spirit and scope of the present disclosure. All such changes and modifications are intended to be within the scope of protection of the present application as defined by the claims. The present application is defined by the appended claims, and equivalents of these claims are intended to be included therein.
