Description

Technical Field

[0001] This utility model relates to the field of steam garment steamer technology, specifically to a water pump supply device for a steam garment steamer. Background Technology

[0002] Garment steamers, a common household ironing device, use heated water to generate steam for smoothing and conditioning clothing. However, existing garment steamers have several technical flaws in their design and use, seriously affecting user experience and posing safety hazards. First, ordinary garment steamers generally suffer from slow steam output and poor steam stability. Second, in daily use, under unfavorable conditions, condensation from the steam in the pipe can block the steam outlet, preventing steam from escaping. This causes the internal pressure of the steam generator to rise, leading to water flowing back into the water tank, resulting in steam interruption and circuit breaker tripping. Third, the backflow of hot water from the generator into the water tank can severely damage the tank. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a water pump supply device for a steam garment steamer, so as to solve the problems of slow and unstable steam output, easy dry burning, water pump backflow and steam interruption, and abnormal water level detection in existing garment steamers.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] A water pump supply device for a steam garment steamer includes a large water tank, a storage tank, a boiler, and a water pump. The large water tank has a cover on top. The outlet of the large water tank is connected to the inlet of the water pump via a water pipe, and the outlet of the water pump is connected to the inlet of the storage tank via a water pipe. The outlet of the storage tank is connected to the inlet of the boiler via a water pipe. The boiler has an outlet for outputting steam. The installation height of the water pump is higher than the maximum water level of the large water tank. The storage tank has PCB microcomputer-controlled sensing electrodes and a conical inclined surface on the inner wall of the top.

[0006] The basic framework of the steam garment steamer's water tank and pump is constructed through a series structure of "large water tank - water pump - water storage tank - boiler," combined with a high-level pump installation design. This fundamentally solves the core problems of slow steam output, water pump backflow interruption, and dry-burning hazards in existing technologies: Dual-tank staged water supply avoids the low heating efficiency of a single-tank system; the high-level pump installation prevents backflow-induced "steam interruption"; the continuous water supply from the water storage tank to the boiler reduces the risk of boiler dry-burning due to water shortage; and the boiler's outlet structure ensures stable steam output. The conical slope on the top inner wall guides the backflow of steam condensate, reducing condensate buildup and scale formation at the top, while also preventing condensate from dripping directly onto the water level detection area and affecting detection accuracy.

[0007] Optionally, the large water tank has a volume of 4L, is made of food-grade ABS material, and has a vent valve on the lid for balancing the air pressure inside the tank.

[0008] The 4L large capacity design meets the water storage needs of the garment steamer for long-term continuous use, avoiding frequent water replenishment by users; the food-grade ABS material ensures that no harmful substances are released when the water tank comes into contact with water, ensuring safe use; the vent valve on the lid solves the problem of "negative pressure interruption" caused by the decrease in internal air pressure when water is discharged from the large water tank, maintaining the stability of water supply.

[0009] Optionally, the water storage tank has a volume of 80-120ML and is made of PP material.

[0010] The small capacity of 80-120ML is compatible with the boiler capacity, ensuring that only a small amount of water is heated in the boiler at any given time, achieving rapid vaporization to solve the problem of slow steam output; the PP material is corrosion-resistant and high-temperature resistant, which can prevent rusting or release of impurities after long-term contact with water and heating.

[0011] Optionally, the angle between the conical inclined surface and the top plane of the water storage tank is 15°-45°.

[0012] An angle range of 15°-45° ensures efficient condensate return: if the angle is too small, water droplets will easily stagnate on the slope, and if the angle is too large, the slope will occupy too much space inside the water tank.

[0013] Optionally, the system also includes at least two waterless detection chips, one of which is disposed on the lower part of the inner wall of the large water tank for detecting the water level in the large water tank; the other of which is disposed on the lower part of the inner wall of the storage tank for detecting the water level in the storage tank.

[0014] By setting up dual waterless detection chips, the water levels of the large water tank and the storage tank can be monitored separately: the detection chip of the large water tank can remind the user to add water in time to avoid the water supply to the storage tank being interrupted due to the large water tank being short of water; the detection chip of the storage tank is directly linked to the anti-dry burning protection to prevent the boiler from burning dry when the storage tank is short of water. This solves the problem of the single water level detection system and the easy false alarm in the existing technology, and improves the safety and continuity of equipment use.

[0015] Optionally, the waterless detection chip is a capacitive non-contact water level detection chip; the water level detection threshold of the waterless detection chip installed in the large water tank is 10% of the volume of the large water tank, and the water level detection threshold of the waterless detection chip installed in the storage tank is 20% of the volume of the storage tank.

[0016] The capacitive contactless design solves the problem of false alarms caused by scale buildup in traditional contact detection chips, and is compatible with both purified water and tap water (avoiding the failure of contact chip detection due to the low conductivity of purified water); specific detection thresholds (10% for the large water tank and 20% for the storage tank) balance "early warning" and "avoiding false alarms": the 10% threshold for the large water tank allows users time to replenish water, and the 20% threshold for the storage tank allows reaction time for anti-dry burning protection.

[0017] Optionally, a waterless detection chip installed in the water storage tank is electrically connected to the boiler's heating circuit; when the waterless detection chip detects that the water level in the water storage tank is lower than a preset threshold, the boiler's heating circuit is automatically disconnected; a waterless detection chip installed in the large water tank is electrically connected to the garment steamer's panel prompt module; when the large water tank detects that the water level is lower than a preset threshold, the panel prompt module displays a low water level alarm message.

[0018] A linkage mechanism is established between the waterless detection chip, the equipment circuit, and the prompt module to achieve intelligent control of "anti-dry burning" and "water replenishment reminder": the water storage tank detection chip is linked with the boiler heating circuit to cut off the risk of dry burning at the source; the large water tank detection chip is linked with the panel prompt module to provide users with intuitive water replenishment guidance, solving the problems of untimely dry burning protection and unclear water replenishment reminders in the existing technology, and improving the safety and convenience of equipment use.

[0019] Alternatively, the boiler may be a one-piece copper structure, and the volume of the boiler may be adapted to the volume of the water storage tank.

[0020] The one-piece copper structure utilizes copper's excellent thermal conductivity to improve boiler heating efficiency and solve the problem of slow heating in existing garment steamers.

[0021] Optionally, the water pipes between the large water tank and the water pump, the water pipes between the water pump and the water storage tank, and the water pipes between the water storage tank and the boiler are all high-temperature resistant silicone pipes.

[0022] High-temperature resistant silicone tubing can withstand the temperature changes of the water inside the tubing during garment steamer operation (from room temperature to near boiling point), preventing low-temperature brittleness or high-temperature aging.

[0023] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0024] Rapid and stable steam output: The dual-tank design of "4L large water tank + 80-120ML small storage tank" combined with a copper boiler ensures that only a small amount of water is heated in the boiler at any given time, significantly shortening the preheating time (20-30 seconds faster than the traditional single water tank); at the same time, the large water tank continuously replenishes water to the storage tank, avoiding water temperature fluctuations caused by mid-process water replenishment, and solving the problems of unstable steam and nozzle condensate overflow.

[0025] Safer by preventing dry burning: The small-capacity design of the water storage tank reduces the risk of dry burning from the source. Combined with the linkage between the waterless detection chip in the water storage tank and the boiler heating circuit, heating can be cut off immediately when water is insufficient, completely eliminating dry burning accidents.

[0026] No backflow steam cut-off: The water pump is installed at a height higher than the maximum water level of the large water tank. The gravity difference is used to prevent water from flowing back into the pipes, ensuring continuous steam generation and extending the service life of the water pump.

[0027] Reliable water level detection: The conical slope on the top of the water tank can guide the condensation of water vapor into water droplets and reduce the accumulation of scale in the detection area; combined with the capacitive non-contact waterless detection chip, it not only avoids false alarms caused by scale adhesion, but also enables the use of both purified water and tap water, improving the equipment's adaptability.

[0028] Sealed and durable: High-temperature resistant sealing pipes and sealing rings are used in all connection parts to prevent water leakage and heat loss, thereby improving the overall durability of the equipment. Attached Figure Description

[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0033] Example 1

[0034] Combined with appendix Figure 1-2A water pump supply device for a steam garment steamer includes a large water tank 1, a storage tank 2, a boiler 3, and a water pump 4. The large water tank 1 is equipped with a cover 11 on top. The outlet of the large water tank 1 is connected to the inlet of the water pump 4 through a water pipe. The outlet of the water pump 4 is connected to the inlet of the storage tank 2 through a water pipe. The outlet of the storage tank 2 is connected to the inlet of the boiler 3 through a water pipe. The boiler 3 is equipped with an outlet 31 for outputting steam. The installation height of the water pump 4 is higher than the maximum water level of the large water tank 1. The storage tank 2 has PCB microcomputer control sensing electrodes and a conical inclined surface 21 on the inner wall of the top. The large water tank 1 serves as the basic water storage unit, and water is transported to the water pump 4 through water pipes. Since the installation height of the water pump 4 is higher than the maximum water level of the large water tank 1, the gravity difference is used to prevent the water flow in the water pipe from flowing back due to the water level difference, ensuring the stability of the water pump 4's pumping direction. The water pump 4 pressurizes the water and delivers it to the water storage tank 2. The water storage tank 2 serves as a transfer unit, continuously supplying water to be heated to the boiler 3, preventing the boiler 3 from heating slowly due to excessive water volume. The boiler 3 heats and vaporizes the input water, and the generated steam is delivered to the nozzle through the outlet 31 to achieve continuous steam production. At the same time, the buffering effect of the water storage tank 2 reduces the temperature fluctuation of the boiler 3 caused by sudden water replenishment.

[0035] The large water tank 1 has a capacity of 4L and is made of food-grade ABS material. The lid 11 is equipped with a vent valve to balance the internal air pressure. The 4L capacity can store a sufficient amount of water to be heated, supporting the garment steamer's continuous operation for several hours with minimal need for refills. The food-grade ABS material has excellent high-temperature resistance and chemical stability. Even when exposed to small amounts of heat conducted through the water pipes during operation, it will not deform or release toxic substances, meeting household appliance safety standards. When water in the large water tank 1 flows through the water pipes to the water pump 4, the internal space increases, and the vent valve automatically opens, allowing outside air to enter the tank, balancing the internal and external air pressure. This prevents a decrease or interruption in water flow due to pressure differences, ensuring a stable water supply to the water pump 4.

[0036] The water storage tank 2 has a volume of 80-120ml and is made of PP material. The small volume of 80-120ml allows the water in the water storage tank 2 to be quickly filled by the water pump 4 and transported to the boiler 3. The boiler 3 can quickly reach the vaporization temperature without heating a large amount of water, shortening the steam production time. The PP material will not oxidize or rust when in contact with water and when subjected to the heat conducted by the boiler 3, avoiding rust from mixing into the water and clogging the water pipes or contaminating the steam. The small amount of water vapor generated by the heating of the water in the water storage tank 2 rises to the top and condenses into water droplets after contacting the cooler inner wall. The inclined structure of the conical slope 21 causes the water droplets to flow back to the bottom of the water storage tank 2 under the action of gravity, and re-participate in the heating cycle, which reduces water accumulation at the top and reduces the probability of scale adhering to the top.

[0037] The angle between the conical inclined surface 21 and the top plane of the water storage tank 2 is 15°-45°, and the surface of the conical inclined surface 21 is polished. The 15°-45° angle ensures that the gravitational component of the condensate on the inclined surface is greater than the adhesion force between the water droplet and the inclined surface, ensuring that the water droplet can smoothly slide down the inclined surface to the bottom of the water storage tank 2, avoiding water accumulation due to improper angle. The polishing treatment reduces the surface roughness of the inclined surface, making it difficult for scale particles to adhere to the smooth surface. Even if a small amount of scale is formed, it is easy to fall off with the condensate, reducing the risk of scale accumulating on the inclined surface and forming hard lumps over a long period of time. At the same time, the smooth surface reduces the flow resistance of condensate, further improving the return flow efficiency.

[0038] The structure of this embodiment also includes at least two waterless detection chips 5. One waterless detection chip 5 is disposed on the lower inner wall of the large water tank 1 to detect the water level in the large water tank 1; the other waterless detection chip 5 is disposed on the lower inner wall of the storage tank 2 to detect the water level in the storage tank 2. The two waterless detection chips 5 are respectively installed on the lower inner walls of the large water tank 1 and the storage tank 2. This position can detect the water level dropping to the critical value as early as possible: when the water level in the large water tank 1 drops to the lower inner wall due to continuous water supply, the corresponding detection chip triggers a water level signal, indicating that the water volume in the large water tank 1 is insufficient; when the water level in the storage tank 2 drops to the lower inner wall due to water supply to the boiler 3, the corresponding detection chip triggers a signal simultaneously, promptly reporting the water shortage status of the storage tank 2, providing basic data for subsequent linkage heating circuits or water replenishment mechanisms, and avoiding misjudgment caused by a single detection chip being unable to distinguish the water levels of the two water tanks.

[0039] The waterless detection chip 5 is a capacitive non-contact water level detection chip. The water level detection threshold of the waterless detection chip 5, located in the large water tank 1, is 10% of the volume of the large water tank 1, while the water level detection threshold of the waterless detection chip 5, located in the storage tank 2, is 20% of the volume of the storage tank 2. The capacitive non-contact detection chip determines the water level by detecting changes in capacitance between the chip and the water in the tank. It does not require direct contact with the water, thus preventing scale buildup on the chip's sensing surface and avoiding detection anomalies caused by scale buildup in traditional contact chips. This type of chip has low requirements for water conductivity; it can accurately identify the water level through capacitance changes, whether using tap water (which has higher conductivity) or purified water (which has lower conductivity), achieving water quality adaptability. When the water level in the large water tank 1 drops to 10% of its volume, the chip's capacitance value reaches the preset threshold, triggering a low water level signal. When the water level in the storage tank 2 drops to 20% of its volume, the chip also triggers the threshold signal, ensuring timely feedback before the tanks are completely empty.

[0040] The waterless detection chip 5, located in the water storage tank 2, is electrically connected to the heating circuit of the boiler 3. When the waterless detection chip 5 detects that the water level in the water storage tank 2 is lower than a preset threshold, the heating circuit of the boiler 3 automatically disconnects. The waterless detection chip 5, located in the large water tank 1, is electrically connected to the panel prompt module of the garment steamer. When the water level in the large water tank 1 is detected to be lower than a preset threshold, the panel prompt module displays a low water level alarm message. When the waterless detection chip 5 in the water storage tank 2 detects that the water level is lower than the preset threshold (20% of the volume), the chip sends an electrical signal to the heating circuit of the boiler 3, triggering the relay of the heating circuit to disconnect, causing the heating wire to stop working, thus preventing the boiler 3 from continuing to heat in a water-deficient state, which could lead to component damage or safety accidents. When the waterless detection chip 5 in the large water tank 1 detects that the water level is lower than the preset threshold (10% of the volume), the chip sends a signal to the panel prompt module of the garment steamer (such as an LED display or indicator light). After receiving the signal, the prompt module reminds the user to add water to the large water tank 1 by displaying the text "low water level" or illuminating the alarm light, ensuring the continuous and stable operation of the equipment.

[0041] Boiler 3 is a one-piece copper structure, and its volume is matched with that of water tank 2. Copper has a much higher thermal conductivity than materials such as stainless steel, allowing the heat generated by the heating wire to be quickly transferred to the water inside through the copper boiler 3 wall, shortening the time it takes for the water to rise from room temperature to boiling point. The volume of boiler 3 is matched with that of water tank 2 (80-120ML), ensuring that the water supplied by water tank 2 at one time can just fill or nearly fill boiler 3, avoiding localized overheating due to insufficient water or prolonged heating time due to excessive water. The 2200W heating wire power is matched with the volume of boiler 3, and the heat generated per unit time can quickly bring the water inside boiler 3 to the vaporization temperature. The generated steam is continuously output through outlet 31, avoiding problems such as low steam pressure and weak steam output due to insufficient heating power.

[0042] The water pipes between the large water tank 1 and the water pump 4, the water pipes between the water pump 4 and the water storage tank 2, and the water pipes between the water storage tank 2 and the boiler 3 are all made of high-temperature resistant silicone tubing. When the garment steamer is working, water in the tubing is transported from the large water tank 1 (at room temperature) to the water storage tank 2, and then enters the boiler 3 (near boiling point). The high-temperature resistant silicone tubing, with a temperature range of -40℃ to 200℃, can adapt to this temperature fluctuation. It will not soften or deform due to increased water temperature, nor will it crack due to low-temperature storage. The 6-10mm diameter is matched with the flow rate of the water pump 4. When the water pump 4 pumps water, the water flow speed in the tubing is stable. It will not cause high water flow resistance and low pumping efficiency due to too small a pipe diameter, nor will it cause excessive residual water in the tubing due to too large a pipe diameter, resulting in a drop in water temperature during the water replenishment interval and affecting the heating efficiency of the boiler 3.

[0043] Workflow: Open the cover 11 to fill the large water tank 1 with water, close the cover 11 and start the equipment; the water pump 4 pumps the water in the large water tank 1 to the storage tank 2. When the water level in the storage tank 2 reaches 80ML (80% full capacity), the water pump 4 stops; the water in the storage tank 2 flows naturally into the boiler 3, the heating wire of the boiler 3 starts, and the water is heated to vaporization within 15 seconds. The steam is output from the outlet 31 through the air guide pipe to the nozzle; when the water level in the storage tank 2 drops to 20ML, the waterless detection chip 5 sends a signal, the water pump 4 restarts to replenish water, and if the water level continues to be lower than 20ML (such as when the large water tank is short of water), the heating wire of the boiler 3 is immediately de-energized; when the water level in the large water tank 1 is lower than 400ML, the equipment panel displays a low water level prompt to remind the user to replenish water.

[0044] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
