Abstract
Description
Technical Field
[0001] This invention relates to a sterilization washing machine. Background Technology
[0002] The sterilization technologies commonly used in washing machines in daily life include the following three:
[0003] 1. Silver ion sterilization technology: Generally, it has a built-in "silver ion generator". During the water intake process, it uses the principle of electrolysis to decompose silver ions from silver sheets with a purity of 99.9%. The silver ions are then carried into the washing tub with the water flow, attracting bacteria in the stains of clothes and destroying their cell walls, leading to the death of the bacteria.
[0004] 2. Ozone technology: Ozone is one of the strongest known oxidants. It is a broad-spectrum, efficient, and fast bactericide. It has a strong killing effect on bacteria, viruses, and microorganisms that cause diseases in humans and animals.
[0005] 3. High-temperature sterilization technology: Heating water to above 90℃ uses high temperature to coagulate or denature the proteins and enzymes of microorganisms, thus killing them and eliminating bacteria and viruses in clothing. This is the most widespread and easiest sterilization method, and most washing machines currently have a high-temperature washing mode.
[0006] However, the above sterilization technologies have various drawbacks:
[0007] 1. Silver ion sterilization technology: Silver ions cannot kill all bacterial cells in laundry solutions, especially those with thick cell walls.
[0008] 2. Ozone Technology: The most fatal problem with ozone is that only 5% is soluble in water, with 95% escaping into the air. In a home environment, increased ozone levels can damage the body's mucous membranes, such as the nasal mucosa, oral mucosa, and respiratory system, causing significant harm over time. Furthermore, while ozone has bactericidal properties, its strong oxidizing properties can cause colored clothing to fade. Therefore, dark-colored clothes should not be washed for extended periods in washing machines with ozone sterilization functions, otherwise they will gradually lose their color and become unsightly.
[0009] 3. High-temperature sterilization technology: First, this method can only kill common bacteria. For bacteria with spores, boiling for at least 1-2 hours daily for 3 consecutive days is required to meet sterilization requirements, which is impractical for washing machines. Second, to achieve sterilization, the water in the washing machine's outer drum needs to be electrically heated to over 90°C. Due to the large volume of water in washing machines and their poor heat retention, this results in significant energy consumption.
[0010] Therefore, the applicant's prior patent CN20793902U discloses a simple water catalyst sterilization washing machine, which comprises a washing machine body, a water catalyst generator and a control panel, wherein the washing machine body comprises a washing machine outer cylinder and a washing machine inner cylinder, the water catalyst generator is arranged on the washing machine outer cylinder, the water catalyst generator must be arranged below the liquid level of washing water, water molecules are decomposed by the water catalyst generator to release strong oxidizing substances for sterilization and disinfection of washing objects in the washing machine, a drain port is connected with the bottom of the water catalyst generator box to remove dirt around the water catalyst generator through the suction of the water outlet, and the control panel controls the washing process of the whole washing machine. The washing machine directly fixes and installs the water catalyst generator at the bottom of the outer barrel wall of the washing machine. On the one hand, water and dirt will accumulate at the bottom of the generator box, and the water outlet needs to be arranged at the bottom of the generator box and connected with the drain port of the washing machine to drain the accumulated water in the generator during drainage. This not only increases the installation of the drain pipe of the generator, but also makes the corner of the bottom of the generator cabin a dead angle, which is easy to hide dirt. At the same time, the water flow passing through the generator box is hindered, the sterilization device is affected, and the sterilization effect is affected.
[0011] Therefore, a washing machine which can fully save space, has good sterilization effect, does not need to add a drain pipe, and has no sewage and dirt in the cabin body becomes the goal of those skilled in the art. SUMMARY
[0012] The first object of the present application is to solve the problem that the sterilization device of the existing washing machine needs to be provided with a drain port and a drain pipe, and to achieve the purpose of self-drainage.
[0013] The second object of the present application is to solve the problem that the sterilization device of the existing washing machine has poor water flow in the box body, resulting in poor sterilization effect.
[0014] In order to achieve the above-mentioned first object, the technical scheme adopted by the present application is as follows: a sterilization washing machine, which comprises a shell, an outer barrel and a rolling barrel, characterized in that at least one sterilization component cabin is arranged on the outer wall of the outer barrel, a sterilization component is arranged in the sterilization component cabin, and the sterilization component cabin and the sterilization component are located below the water level line of the washing machine; the installation position of the outer barrel wall corresponding to the sterilization component cabin is in an open shape or has a plurality of water passing holes; the sterilization component cabin comprises a bottom plate located at the bottom, the bottom plate is arranged downwardly inclined from the inside of the cabin body to the cabin opening direction, and the lowest position of the bottom plate is higher than the lowest position of the outer barrel of the washing machine.
[0015] As two preferred solutions, the sterilization washing machine comprises two side plates, i.e., a first side plate and a second side plate, and at least two back plates, i.e., a first back plate and a second back plate; the sterilization component cabin is formed by the first back plate, the second back plate, the first side plate and the second side plate into a columnar shell with an open front end surface, a three-sided or polygonal cross section perpendicular to the center line direction of the outer drum of the washing machine; and the bottom plate at the bottom of the sterilization component cabin is the first back plate or the first side plate. When the first back plate is the bottom plate, it is suitable for a drum washing machine, and when the first side plate is the bottom plate, it is suitable for a pulsator washing machine.
[0016] In order to achieve the second object, the first back plate and the second back plate of the sterilization component cabin are arranged at an angle greater than 90°, and when there are multiple back plates, the included angle between the back plates is greater than 90°, so that when the water flows through the sterilization component cabin, no dead angle is formed, the water flow is smooth, no obstruction is formed, and the water flow is fully contacted with the sterilization components, thereby promoting the sterilization effect.
[0017] In order to make the inner end of the sterilization component cabin not store dirt, as a preferred solution, the included angle between the bottom plate and the back plate is an obtuse angle greater than 90°, and the included angle between the bottom plate and the back plate is an obtuse angle, which is more conducive to the discharge of sewage and dirt and is not easy to cause the accumulation of foreign matters.
[0018] As a preferred way, the sterilization components kill bacteria by generating hydroxyl radicals (·OH) through splitting water. That is, a water catalyst purification device (water catalyst generator) is used, and the working principle is that water generates hydroxyl radicals under the action of electrodes, which are formed by losing an electron from hydroxyl radicals, have a strong ability to obtain electrons, and react with organic matter to oxidize the organic matter into stable oxygen, carbon dioxide, water, mineral salts and the like harmless to the human body, and at the same time, can destroy the structure of bacteria and the genetic material of viruses, so that the bacteria cannot survive and the viruses cannot reproduce, thereby playing a role in sterilization and disinfection.
[0019] The sterilization washing machine adopts the above technical solutions, the bottom plate of the sterilization component cabin is designed to be inclined from low outside to high inside, i.e., the inner end of the cabin body is high and the outlet of the cabin body (close to the barrel wall of the outer drum of the washing machine) is low, and the lowest point of the bottom plate is higher than the lowest point of the outer drum of the washing machine, so that the water in the sterilization component cabin can flow back into the outer drum of the washing machine, achieving the purpose of self-drainage, thereby ensuring that there is no water and dirt in the sterilization component cabin, keeping the sterilization component cabin dry and clean, and avoiding pollution; and further, there is no need to set a water outlet and a drainage pipeline at the bottom of the cabin body, thereby greatly saving the cost and installation space.
[0020] The shape of the sterilization component cabin is designed as a columnar shell with an open front end surface, a three-sided or polygonal cross section perpendicular to the center line direction of the outer barrel of the washing machine, and formed by at least two back plates and two side plates, and by setting the included angle between the back plates of the sterilization component cabin to an obtuse angle greater than 90°, there is no dead angle, the flow of water is facilitated, and the water flows smoothly through the sterilization component, increases the cracking of the sterilization component to water, and can improve the sterilization effect.

DETAILED DESCRIPTION
[0034] The preferred embodiments of the present application are described in detail below with reference to the accompanying drawings, but the protection scope of the present application should not be limited by the preferred embodiments.
[0035] Embodiment one, see Figure 1 , a sterilization washing machine is shown in the figure, which comprises a shell 203, an outer barrel 201 and an inner barrel 202; a sterilization component cabin 2 is arranged on the outer wall of the outer barrel 201, and a sterilization component 1 is arranged in the sterilization component cabin 2; the sterilization component cabin 2 and the sterilization component 1 constitute a sterilization device 100; the barrel wall of the outer barrel 201 of the washing machine is open at the mounting position corresponding to the sterilization component cabin 2, obviously, it can also be a grid with a plurality of holes, so that the washing cavity of the outer barrel 201 is communicated with the sterilization component cabin 2, so that the water in the barrel of the washing machine can directly enter the sterilization component cabin 2, and the sterilization component cabin 2 is located below the water level line L of the washing machine, so as to ensure that the sterilization component is fully contacted with the water in the washing machine; the sterilization component cabin 2 comprises a bottom plate located at the bottom of the cabin body, and the bottom plate is arranged downwardly inclined from the inside of the cabin body to the direction of the hatch, obviously, the bottom plate can be a straight plate arranged in an inclined manner, or can be arc-shaped; and the lowest position of the bottom plate is higher than the lowest position of the outer barrel 201 of the washing machine, so as to ensure that the water flows back to the outer barrel 201 of the washing machine, so that the sterilization component cabin 2 does not store water, and the cleanliness of the sterilization component cabin 2 is maintained. Since the sterilization component cabin 2 of the present application adopts the inclined bottom plate, it does not need to additionally arrange a water outlet and a drain pipe at the bottom of the cabin body, thereby saving the space occupied by the sterilization component cabin in the washing machine, achieving the purpose of automatic drainage, and completely solving the problem of water storage in the sterilization component cabin 2.
[0036] See Figure 1 , 3, 4, the figure shows the sterilization part cabin 2 described in the embodiment, in order to make the water flow through the sterilization part cabin 2, so as to improve the sterilization effect, the specific structure of the sterilization part cabin 2 is: it includes two side plates and at least two back plates, two back plates in this embodiment: the first back plate 21 and the second back plate 22, two side plates: the first side plate 231 and the second side plate 232, the sterilization part cabin 2 is surrounded by the first back plate 21 and the second back plate 22, the first side plate 231 and the second side plate 232 to form a columnar shell with an open front end, which is perpendicular to the center line direction of the outer barrel of the washing machine, and the cross section is a triangle, that is: the first back plate 21 and the second back plate 22 are flat plates, in this embodiment, the first back plate 21 is used as the bottom plate located at the bottom of the sterilization part cabin. The included angle between the first back plate 21 and the second back plate 22 is greater than 90°. By setting the included angle between the first back plate 21 and the second back plate 22 as obtuse, that is, the included angle between the bottom plate and the second back plate 22 is obtuse, so that the end of the sterilization part cabin 2 does not form a dead angle, which is not easy to cause foreign matter accumulation, which is beneficial to the discharge of foreign matter, helps the water flow smoothly, and does not form resistance, which is beneficial to the contact between water and sterilization part, promotes the generation of hydroxyl radical (·OH) to kill bacteria, and improves the sterilization effect. At the same time, since the sterilization part cabin 2 is located below the water level line of the washing machine, the lowest position of the bottom plate 22 is higher than the lowest position of the outer barrel 201 of the washing machine, so that the sterilization part cabin 2 is installed at the lower right corner of the washing machine, therefore, the sterilization part cabin 2 adopts the columnar shell shape with a triangular cross section in this embodiment, which can just use the space of the outer barrel at the lower right corner or the lower left corner of the washing machine, so it can greatly save the space occupied by the installation of the sterilization part cabin.
[0037] The front edge of the first side plate 231 and the second side plate 232 has a shape matched with the barrel wall of the washing machine, so that it is installed in the outer barrel 201. Specifically, the front end face of the sterilization part cabin 2 has a mounting flange 24, that is, the mounting flange 24 is arranged at the front edge of the first side plate 231, the second side plate 232, the first back plate 21 and the second back plate 22, a plurality of mounting holes 25 are arranged on the mounting flange 24, and the sterilization part cabin 2 is fixed on the side wall of the outer barrel 201 of the washing machine by screws. Further, a sealing groove 26 is arranged around the end face of the mounting flange 24, and a sealing rubber strip 4 is embedded in the sealing groove 26 to realize the end face sealing of the sterilization part cabin 2. The second back plate 22 is provided with a fixing hole 27 of the sterilization part 1, and the sterilization part 1 is fixed and installed on the second back plate 22 by bolts and other fixing members.
[0038] Embodiment two, see Figure 2 , which shows a sterilization washing machine, which is different from the last embodiment: it is installed with two sterilization part cabins, two sterilization parts, which are respectively located at the left and right lower corners of the outer barrel of the washing machine.
[0039] Embodiment three, seeFigure 5 Figure 1 shows another washing machine, which is different from the first and second embodiments in that it is a pulsator washing machine, which is provided with two sterilization devices on the wall of the outer barrel 201, which are located in the upper left corner and the lower right corner in the top view, respectively. The sterilization device 100 in this embodiment is different from the sterilization device in the first embodiment in that, when installed, the second side plate 232 of the sterilization component cabin 2 is the bottom plate, which is installed below, and the first side plate 231 is above, specifically, see Figure 9 、 10 , 11, Figure 1 shows the sterilization component cabin 2 in this embodiment, which also includes two back plates: the first back plate 21 and the second back plate 22, two side plates: the first side plate 231 and the second side plate 232, and a three-edged columnar shell with an open front end face and a center line direction perpendicular to the washing machine outer barrel, which is surrounded by the first back plate 21 and the second back plate 22, the first side plate 231 and the second side plate 232. In this embodiment, the second side plate 232 is the bottom plate, which is inclined at this time, from inside to outside, and is inclined downward, i.e. the circular arc edge of the second side plate 232 near the hatch is lower than the intersection point of the two straight edges (the inner end of the cabin). At the same time, the angle between the first back plate 21 and the second back plate 22 is obtuse, which is beneficial to the smooth flow of water, and at the same time, the angle between the first side plate 231 as the bottom plate and the first back plate 21 and the second back plate 22 is also obtuse, which is beneficial to the discharge of dirt and prevents the accumulation of foreign matter.
[0040] Embodiment four, see Figure 6 , which is different from the previous embodiment in that the two sterilization devices 100 are located in the upper right corner and the lower left corner, respectively.
[0041] Embodiment five, see Figure 7 、 8 , which is different from the previous embodiment in that it is provided with four sterilization devices 100, which are located in the four corners, respectively. It is the best solution to place the sterilization device 100 in the corner, which can make full use of the space of the pulsator washing machine in the four corners of the shell without the need to increase the space for installing the sterilization device of the washing machine. See Figure 8 , Figure 1 shows a side view of the sterilization component cabin 2 installed on the washing machine outer barrel 201, which is inclined downward from inside to outside.
[0042] See Figure 12, the structure of another sterilization component cabin 2 is shown in the figure, which transforms the columnar shell with triangular cross section into the columnar shell with quadrilateral cross section, the front end is also open and arc-shaped, and an additional back plate is added: the third back plate 23, that is, with three back plates, this shape is more conducive to water flow and does not form vortex, so that the water flow is smoother. However, the disadvantage is that it occupies more space. Therefore, in the above embodiment, the sterilization component cabin is designed as follows: a columnar shell with an open front end and a longitudinal cross section of a triangular shape that is adapted to the shape of the anode and cathode plates is surrounded by the first back plate 21, the second back plate 22, the first side plate 231 and the second side plate 232, so that the space of the corner of the washing machine can be fully utilized, and the installation space of the sterilization device can be saved.
[0043] The above description is only illustrative and not limiting, and the present application aims to provide a sterilization washing machine, which sets the sterilization component cabin on the outer barrel wall and below the water level, and at the same time, the bottom plate of the sterilization component cabin is inclined downward from inside to outside, so that a separate drain port is not needed, and those skilled in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined in the claims, for example: changing the shape of the sterilization component cabin, increasing or decreasing the number of back plates, and making it into a columnar shell shape with a polygonal cross section, but all will fall within the protection scope of the present application.
