[0002] The working principle of ironing equipment is mainly to clean through steam. It uses saturated steam under high temperature and high pressure to dissolve the oil particles on the surface to be cleaned, and vaporize and evaporate them, which can effectively peel off and remove stains and residues. Generally, ironing equipment is equipped with a steam generation system with a water pump and a water tank, which can quickly convert clean water into high-temperature and high-pressure strong steam within 30 seconds. At the same time, various bacteria, mites, microorganisms and pathogens attached to objects are completely eliminated.

[0031] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the accompanying drawings to explain the present invention in detail. Figure 7 The top-down direction shown in the middle paper is the top-down direction in this embodiment.

[0032] See also Figures 1 to 7 As shown in , the double-water-inlet double-cavity independent temperature-controlled steam boiler provided in this embodiment includes:

[0033] The main body 1 has two upper vaporization chambers 7 and lower vaporization chambers 8 arranged vertically and isolated from each other, and the main body 1 is provided with a first heating body 23 for controlling the vaporization temperature in the upper vaporization chamber 7 and a second heating body 24 for controlling the vaporization temperature in the lower vaporization chamber 8;

[0034] In addition, the main body 1 is also formed with a first liquid inlet 3 connected to the upper vaporization chamber 7, and a second liquid inlet 4 connected to the lower vaporization chamber 8, which are used to inject liquid into the upper vaporization chamber 7 and the lower vaporization chamber 8, respectively; the outer wall of the main body 1 is also formed with at least one first steam outlet 14 connected to the upper vaporization chamber 7, and at least one second steam outlet 15 connected to the lower vaporization chamber 8, which are used to flow out the steam in the upper vaporization chamber 7 and the lower vaporization chamber 8, respectively.

[0035] Based on the above technical solution, a double-water-inlet double-chamber independently temperature-controlled steam boiler includes a main body 1, in which an upper vaporization chamber 7, a lower vaporization chamber 8, a first heating body 23, a second heating body 24, a first steam outlet 14, a second steam outlet 15, a first liquid inlet 3, and a second liquid inlet 4 are provided, so that the purpose of double water inlet double chamber and independent temperature control can be achieved, and the vaporization degree in the vaporization chamber can be effectively improved.

[0036] In a preferred embodiment, specifically as Figures 3 to 5 As shown in the figure, the main body 1 includes an upper furnace body 5 and a lower furnace body 6 which are assembled into one body, an upper vaporization chamber 7 is formed in the upper furnace body 5, and a lower vaporization chamber 8 is formed between the lower furnace body 6 and the upper furnace body 5. Further, the upper furnace body 5 is open and detachably equipped with an end cover 2, and the end cover 2 is provided with a first liquid inlet 3 and a second liquid inlet 4. A flow guide hole 11 connecting the lower vaporization chamber 8 and the second liquid inlet 4 is formed in the upper furnace body 5, and a first liquid inlet assembly 25 is assembled in the first liquid inlet 3, and a second liquid inlet assembly 26 is assembled in the second liquid inlet 4.

[0037] As a further preferred embodiment, a first labyrinth flow channel 21 is formed by a plurality of first isolation ribs 19 in the upper vaporization chamber 7, and the first liquid inlet 3 is adjacent to the starting position of the first labyrinth flow channel 21 and the first steam outlet 14 is adjacent to the end position of the first labyrinth flow channel 21. Further, a second labyrinth flow channel 22 is formed by a plurality of second isolation ribs 20 in the lower vaporization chamber 8, and the second liquid inlet 4 is adjacent to the starting position of the second labyrinth flow channel 22 and the second steam outlet 15 is adjacent to the end position of the second labyrinth flow channel 22. The use of a labyrinth flow channel can effectively increase the vaporization time of the liquid flow in the vaporization chamber, so that the vaporization degree of the steam flowing out of the steam outlet is higher.

[0038] As a further preferred embodiment, the starting position of the second labyrinth flow channel 22 also protrudes upward to form a conical column 27, which is used to guide the liquid flow entering the lower vaporization chamber 8 from the second liquid inlet component 26, thereby avoiding the problem of liquid splashing due to the excessive longitudinal drop between the starting position of the second labyrinth flow channel 22 in the lower vaporization chamber 8 and the second liquid inlet 4.

[0039] As a further preferred embodiment, the first labyrinth flow channel 21 includes two branch flow channels that are mirror-symmetrical, and the starting position of the first labyrinth flow channel 21 is divided into two parts by a rib plate 28 formed in the upper vaporization chamber 7, and the lower end of the first liquid inlet component 25 has two liquid outlet pipes 29 corresponding to the two branch flow channels of the first labyrinth flow channel 21, so that the first liquid inlet component 25 can divert the liquid flow to the two branch flow channels of the first labyrinth flow channel 21, and vaporize along the extension direction of the first labyrinth flow channel 21, so that the vaporization degree is higher.

[0040] It is worth pointing out that a labyrinth-like flow channel is designed in the vaporization chamber, that is, the design of the ribs and partitions in the vaporization chamber makes the flow length of the liquid flow from the starting position to the end position longer, so that the vaporization time is longer, which is beneficial to improving the vaporization rate. This is a conventional choice in this field, but in this embodiment, for the upper vaporization chamber, the flow is diverted from the time the liquid enters, and for the lower vaporization chamber, due to the large height difference, a conical column 27 is designed to guide the liquid flow flowing in from a relatively high place. Its structure is an improvement on the existing labyrinth-like flow channel and also has its practical significance.

[0041] As a further preferred embodiment, the upper furnace body 5 is formed with a first heating channel 10 arranged around the first labyrinth flow channel 21, and the first heating body 23 is contained in the first heating channel 10, which is used to conduct the heat of the first heating body 23 through the wall of the first heating channel 10 to the liquid flow or steam flowing in the first labyrinth flow channel 21 to vaporize the liquid flow. Further, the lower furnace body 6 is formed with a second heating channel 9 arranged around the second labyrinth flow channel 22, and the second heating body 24 is contained in the second heating channel 9, which is used to conduct the heat of the second heating body 24 through the wall of the second heating channel 9 to the liquid flow or steam flowing in the second labyrinth flow channel 22 to vaporize the liquid flow. That is, the purpose of independently controlling the vaporization temperature in the two vaporization chambers can be achieved. Specifically, the two heating bodies can be selected as electric heating tubes and electrically connected to the external main control circuit board to achieve the purpose of temperature control. At the same time, the shape of the two heating channels can be U-shaped, S-shaped, or even a mosquito coil-shaped disc structure, but is not limited thereto.

[0042] In a preferred embodiment, the first isolation rib 19 is integrally formed on the upper end surface of the upper furnace body 5, and the first isolation rib 19 has a plurality of positioning protrusions, and the end cover 2 has positioning holes 16 of the same number and opposite positions as the positioning protrusions, so as to facilitate the detachable connection of the end cover 2. Further, the second isolation rib 20 is integrally formed on the upper end surface of the lower furnace body 6, and the lower end surface of the upper furnace body 5 is formed with a snap-in groove 17 matching the shape of the second isolation rib 20, and the upper end of the second isolation rib 20 is inserted into the snap-in groove 17. This ensures that the two labyrinth-like flow channels will not have a gap on the end surface due to being assembled from top to bottom. At the same time, both sets of grooves are formed with a downwardly protruding structure, but can also be a concave structure, and are not limited to this.

[0043] As a further preferred embodiment, in this embodiment, the number of the first steam outlet 14 and the second steam outlet 15 are both two and they are opened on the same side wall of the upper furnace body 5, and the two first steam outlets 14 and the two second steam outlets 15 are arranged in parallel, and the lower end surface of the upper furnace body 5 is also formed with a guide groove 18 that is recessed upward and connects the second steam outlet 15 and the lower vaporization chamber 8. This makes the steam outlet directions of the two vaporization chambers consistent, so that the steam boiler can be easily configured in the ironing device.

[0044] In addition, if Figure 5 As shown in the figure, the first labyrinth flow channel 21 is constructed into two steam flow channels by the first isolation ribs 19 and corresponds to the two first steam outlets 14 respectively, and the second labyrinth flow channel 22 is also constructed into two steam flow channels by the second isolation ribs 20 and flows to the two second steam outlets 15 respectively through the guide grooves 18 at the tail end. The specific directions of the two groups of isolation ribs are not limited, and the vaporization chamber can be constructed into a labyrinth flow channel. Therefore, its specific direction and arrangement are omitted here, and it is not limited to the shape shown in the figure.

[0045] Refer to Table 1 below, which is a comparison between the double-water inlet double-cavity independent temperature-controlled steam boiler provided by the present application, the upper and lower double-layer boiler with a single electric heating tube as disclosed in Patent No. CN212714192U, and the conventional single-electric heating tube single-layer boiler. The boiler volumes and test voltage powers of the three are basically the same. The former two have a double-cavity design, so that the cavity capacity area of ​​the vaporization cavity is twice that of the latter. The test found that under this condition, the steam volume (proportional to the vaporization rate) of the double-water inlet double-cavity steam boiler provided by the present application is much larger than that of the latter two. At the same time, under the same test voltage and power, the overall boiler temperature of the former is slightly lower than that of the latter two.

[0046]

[0047] (Table 1)

[0048] In addition, the power of the above-mentioned scheme A (i.e., the double-water inlet double-chamber independent temperature-controlled steam boiler provided by this application) can be very large to meet the different needs of different customers. The maximum voltage power can be 230V; 3000W. Under the premise of meeting the vaporization rate requirements, the minimum power can be 120V; 1800W. At the same time, the design of double-chamber double electric heating pipes makes the overall heat distribution of the boiler uniform, while increasing the evaporation contact area of ​​water, greatly increasing the amount of steam per unit time, so that the vaporization rate is higher. The double water inlet design has double water discharge points, so that the water in the boiler is distributed as evenly as possible in the boiler, balancing the ambient temperature of the entire boiler. At present, the overall boiler temperature is tested to be within 210°. The uniform distribution of water can also maximize the use of the heat of the boiler, and under the same conditions, the steam volume can be increased.

[0049] Another example is Solution B, which is a handheld steam brush. Due to its appearance, the boiler cannot be infinitely enlarged, that is, the electric heating tube cannot be enlarged, and the power will be affected. Under normal circumstances, the maximum power can only be 230V; 1600W, and the minimum power that meets the vaporization requirements is 120V; 1400W. Due to the limited volume of the electric heating tube, it cannot provide more energy for the boiler, so the steam cannot be enlarged. In addition, this product has a single point of water discharge, a long boiler channel, a very low water discharge point temperature, and a high ambient temperature of 235°.

[0050] Finally, as in the above solution C, this product is a handheld steam brush. Due to the appearance, the boiler cannot be infinitely enlarged, that is, the electric heating tube cannot be enlarged, and the power will be affected. Under normal circumstances, the maximum can only be 230V; 1600W. The minimum power that meets the vaporization requirements is 120V; 1400W. Due to the inability to increase the overall product power, it is impossible to provide enough energy for the boiler, so the steam cannot be enlarged.

[0051] In summary, compared with the existing double-cavity single electric heat tube solution and the single-cavity single electric heat tube solution, the present application can adopt a higher voltage power, and under the same voltage and power conditions, the steam volume is larger. Based on the basic logic that the greater the power, the higher the vaporization rate, the present application can obtain a higher vaporization rate.

[0052] It is worth pointing out that the double-chamber design arranged up and down provided in the present application can also be set as a double-chamber design arranged side by side left and right or front and back, which can be achieved by simply adjusting the positions of the components. At the same time, it can also be considered to be designed as a three-layer or more layer design up and down, and it only needs to design additional water inlet components, water inlets, water inlet channels and steam outlets accordingly, which can also achieve the technical purpose of improving the vaporization rate.

[0053] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
