Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a steam generator and an integrated stove. Background Technology

[0002] Integrated cooktops are common kitchen appliances, widely favored by consumers for integrating multiple functions such as range hoods, gas stoves, disinfection cabinets, and storage cabinets. Among them, integrated cooktops generally also integrate the function of steam ovens. During the use of steam ovens, water needs to be added to the water-receiving section inside the inner tank. The water inside the water-receiving section is evaporated by heating the outer wall of the water-receiving section. In the current technology, an electromagnetic coil is placed outside the water-receiving section to heat the water inside the inner tank. This solution has a gap between the electromagnetic coil and the water-receiving section, resulting in low efficiency in heat transfer and energy waste.

[0003] Therefore, there is an urgent need to design a steam generator and an integrated stove to solve the above problems. Utility Model Content

The connecting part passes through the first hole and at least part of the second heat-conducting element in sequence. The second locking member is connected to the connecting part so that the second heat-conducting element abuts against the first heat-conducting element.

[0014] As an alternative, the second heat-conducting member has a connected second hole and a third hole, the connecting part passes through the second hole and extends into the third hole, and the second locking member is accommodated in the third hole.

[0040] Example 1

[0041] This embodiment provides a steam generator that can concentrate heat to the water container 12, saving energy. For example... Figures 1-4 As shown, the steam generator includes an inner tank 10 and a heating assembly 20. The bottom plate of the inner tank 10 is recessed outward to form a water-holding portion 12, wherein the recessed portion of the water-holding portion 12 is used to hold a certain volume of water. The heating assembly 20 includes a heating element 21 and a heat-conducting component 22. The upper side of the heat-conducting component 22 abuts against the water-holding portion 12. The heating element 21 is an electromagnetic coil and is disposed around at least a portion of the heat-conducting component 22. It should be noted that the heating element 21 can be powered by alternating current or direct current, as long as it can heat the heat-conducting component 22.

[0042] The aforementioned steam generator, by abutting the lower side of the heat-conducting component 22 against the water-containing section 12, and with the heating element 21 being an electromagnetic coil sleeved around the heat-conducting component 22, conducts heat through the heat-conducting component 22 after the electromagnetic coil is energized with alternating current. Because the heat-conducting component 22 is tightly fitted to the water-containing section 12, heat can be conducted to the water-containing section 12 rapidly and to the maximum extent to heat the water inside. Heat loss during heat conduction is minimal, resulting in greater energy savings. The heating element 21 can be positioned around a portion of the heat-conducting component 22 or around the entire heat-conducting component 22.

[0043] Compared to the traditional solution of welding the heating element to the water container 12, this solution does not require welding the heating element 21 to the water container 12, thus avoiding the problem of weld penetration. In order to prevent the water container 12 from being welded through, the bottom plate of the inner liner 10 and the water container 12 must be manufactured separately, and a sealing element must be added at the joint to prevent water leakage. In contrast, the inner liner 10 of this solution is an integral structure, which facilitates the manufacturing of the inner liner 10 and can prevent water leakage.

[0044] Optionally, such as Figure 2 and Figure 4 As shown, a first connecting member 11 protrudes from the lower side of the water-containing portion 12. The heat-conducting assembly 22 includes a first heat-conducting element 221 and a second heat-conducting element 222. The first connecting member 11 passes through the first heat-conducting element 221. A first locking member 30 is connected to the first connecting member 11 so that the first heat-conducting element 221 abuts against the water-containing portion 12. The second heat-conducting element 222 is columnar and abuts against the side of the first heat-conducting element 221 opposite to the water-containing portion 12. The heating element 21 surrounds the second heat-conducting element 222. With the above arrangement, after the electromagnetic coil is energized with alternating current, the heat passes through the columnar second heat-conducting element 222 and is then conducted to the first heat-conducting element 221. The first heat-conducting element 221 has a larger contact area with the water-containing portion 12, resulting in more uniform and sufficient heat conduction.

[0045] In this embodiment, the first connecting member 11 is a bolt, and the first locking member 30 is a nut, which are threaded together. In another optional embodiment, the first connecting member 11 can also be a rod with a slot, and the first locking member 30 can be a buckle, which engages with the slot.

[0046] That is, the size of the second heat-conducting element 222 is smaller than that of the first heat-conducting element 221, which not only makes it easier for the heating element 21 to be wrapped around the second heat-conducting element 222, but also ensures that the first heat-conducting element 221 and the water-containing part 12 have a large contact area.

[0047] Specifically, the cross-sections of the first heat-conducting element 221 and the second heat-conducting element 222 are both circular, and the cross-sectional diameter of the second heat-conducting element 222 is smaller than the cross-sectional diameter of the first heat-conducting element 221.

[0048] Optionally, such as Figure 2 and Figure 4 As shown, the heating assembly 20 also includes a second connector 23. The first heat-conducting element 221 has a first receiving groove 22111 and a first hole 22112 connected to each other on the side facing the water-containing portion 12. The second connector 23 includes a limiting part 231 and a connecting part 232 connected to each other. The limiting part 231 is accommodated within the first receiving groove 22111 and limited to the bottom of the groove. The connecting part 232 passes through the first hole 22112 and at least a portion of the second heat-conducting element 222 in sequence. A second locking member 24 is connected to the connecting part 232 to make the second heat-conducting element 222 abut against the first heat-conducting element 221. With this configuration, since the limiting part 231 is accommodated within the first receiving groove 22111, it does not affect the state of the first heat-conducting element 221 abutting against the water-containing portion 12, and the second locking member 24 locks it on the other side.

[0049] In this embodiment, the connecting part 232 is provided with external threads on its periphery, and the second locking member 24 is a nut, and the two are threadedly connected. In another optional embodiment, the second connecting member 23 can also be a rod with a groove, and the second locking member 24 is a buckle, which engages with the groove.

[0050] Optionally, such as Figure 5 As shown, the first receiving groove 22111 is a non-circular groove, and the limiting part 231 has a polygonal cross-section, which prevents the second connecting member 23 from rotating when the second locking member 24 is turned. For example, the cross-sections of the first receiving groove 22111 and the limiting part 231 are both hexagonal.

[0051] In an alternative embodiment, the second locking member 24 can directly abut against the side of the second heat conductor 222 away from the first heat conductor 221. However, in this case, the second locking member 24 will protrude from the second heat conductor 222, occupying a certain amount of space.

[0052] In this embodiment, as Figure 4 As shown, the second heat-conducting element 222 has a connected second hole 2221 and a third hole 2222. The connecting portion 232 passes through the second hole 2221 and extends into the third hole 2222. The second locking member 24 is accommodated in the third hole 2222. Thus, the second locking member 24 does not protrude from the second heat-conducting element 222 because it is accommodated in the third hole 2222, reducing the space occupied.

[0053] Optionally, to ensure the stability of the connection, at least two first connectors 11 are provided, and four are provided in this embodiment; at least two second connectors 23 are provided, and two are provided in this embodiment.

[0054] Optionally, the first heat-conducting element 221 is made of aluminum or iron. Aluminum is preferred because these materials have high thermal conductivity, thus achieving efficient heat distribution and conduction.

[0055] Optionally, the second heat-conducting element 222 is made of cast iron or iron, which are materials that are more likely to generate electromagnetic eddy currents.

[0056] Optionally, such as Figure 4 As shown, the size of the first heat-conducting element 221 is greater than or equal to the size of the water-containing part 12, ensuring that the heating surface of the water-containing part 12 is covered and that heat transfer is uniform.

[0057] Specifically, the cross-sections of the first heat-conducting element 221 and the water-receiving part 12 are both circular, and the diameter of the first heat-conducting element 221 is greater than or equal to the diameter of the water-receiving part 12.

[0058] In other embodiments, the cross-sectional shapes of the first heat-conducting element 221, the second heat-conducting element 222, and the water-receiving part 12 can be set as needed, for example, set as a rectangle, a triangle, etc.

[0059] Optionally, such as Figure 4 and Figure 5 As shown, the first heat-conducting component 221 includes a body 2211 and a heat-conducting medium 2212. A second receiving groove 22113 is formed on the side of the body 2211 facing the water-containing part 12. The heat-conducting medium 2212 is contained in the second receiving groove 22113. The first connecting member 11 passes through the heat-conducting medium 2212 and the second receiving groove 22113 in sequence. Both the body 2211 and the heat-conducting medium 2212 abut against the water-containing part 12. The heat-conducting medium 2212 fills the second receiving groove 22113, and the heat-conducting medium 2212 can better fit with the water-containing part 12, thereby increasing the uniformity of heat conduction and effectively avoiding the problem of local yellowing of the inner liner 10 caused by uneven heat.

[0060] Optionally, the thermal conductive medium 2212 is a soft material with a certain degree of fluidity, such as thermal conductive silicone grease. It does not deteriorate or solidify at high temperatures and maintains a non-cured and non-sticky state throughout the product's life cycle. It will not stick during disassembly and is relatively convenient and easy to replace and clean. In this solution, the thickness of the thermal conductive medium 2212 is 0.1-2mm, and the thickness depends on the depth of the second receiving groove 22113.

[0061] Optionally, such as Figure 1 and Figure 2 As shown, the steam generator also includes a temperature sensor 40, connected to the lower side of the water container 12 and used to monitor the temperature of the water container 12. The heating assembly 20 is disposed away from the temperature sensor 40 so that the temperature sensor 40 contacts the water container 12. Specifically, as Figure 2As shown, both the first heat-conducting element 221 and the heat-conducting medium 2212 have clearance holes that match the shape of the temperature sensor 40, so that the temperature sensor 40 can directly contact the water-receiving part 12 after installation. In other embodiments, the temperature sensor 40 can also be waterproofed and then directly installed inside the water-receiving part 12.

[0062] Optionally, such as Figure 1 and Figure 2 As shown, the steam generator also includes a resettable thermostat 50. Two resettable thermostats 50 are provided, and their main function is to prevent the temperature of the first heat-conducting element 221 from becoming too high due to abnormal heat transfer. When the temperature of the first heat-conducting element 221 becomes abnormal and reaches the operating temperature of the resettable thermostat 50, the resettable thermostat 50 will disconnect, cutting off the current to the electromagnetic coil and achieving abnormal over-temperature protection. This part is a conventional safety protection feature in existing technology, and the specific principle will not be elaborated further.

[0063] Optionally, such as Figure 2 As shown, the lower side of the water-containing section 12 also has a protruding connector for mounting the temperature sensor 40 and the resettable thermostat 50. See also... Figure 1 Each temperature sensor 40 corresponds to one connector, and each resettable thermostat 50 corresponds to two connectors. The connectors can be bolts, which are locked by locking nuts.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
