Detailed Description

In order that the utility model described herein may be more fully understood, the following examples are set forth. It should be understood that these examples are for illustrative purposes only and are not to be construed as limiting the invention in any way.

Example one

As shown in fig. 1 to 5, a bottom cover structure having a turbidity sensor 16 is provided in a cabinet of a home appliance such as a refrigerator or a freezer that needs to maintain a certain storage environment. The structure specifically includes: a bottom cover 10 disposed on the household appliance inner container 200, wherein the bottom cover 10 and the top cover 12 together form a holding space for volatile matter for sterilization (the volatile matter refers to sterilization gas or gel or liquid containing the sterilization gas) or reactant for preparing the volatile matter for sterilization, and specifically, chlorine dioxide gas or raw material for preparing chlorine dioxide gas can be placed in the holding space; the bottom lid 10 is close to the household electrical appliances inner bag side and is equipped with the first cavity 103 of holding turbidity sensor 16, and it is from the bottom lid 10 toward being close to the household electrical appliances inner bag side or toward keeping away from the sunken of the extension of household electrical appliances inner bag side direction, and at least part of first cavity 103 is made by transparent material to make turbidity sensor 16 detect the colour change in the accommodation space through the transparent part of first cavity 103, with the surplus change of the interior volatile thing of perception household electrical appliances sterilization module. Specifically, the bottom cover 10 includes a first cavity 103 on a side close to the household appliance inner container 200, the first cavity 103 is a recess extending from the bottom cover 10 to a side close to the household appliance inner container 200 or to a side far from the household appliance inner container 200 to form a cavity for accommodating the turbidity sensor 16, and the turbidity sensor 16 is inserted into the plug wire terminal on the inner container 200; at least the first cavity 103 of the bottom cover 10 is made of a transparent material, so that the turbidity sensor 16 detects a color change in the accommodating space through the first cavity 103 to obtain a residual amount change of the volatile in the home appliance sterilization module 100.

In order to ensure the detection accuracy of the turbidity sensor 16 and ensure that the turbidity sensor 16 maximally contacts the volatile matter in the accommodating space, the first chamber 103 is preferably set as a recess extending from the bottom cover 10 to the side away from the household appliance inner container 200, at this time, the first chamber 103 is located in the accommodating space formed by the bottom cover 10 and the top cover 12, that is, the substance in the accommodating space is set around the turbidity sensor 16, so as to ensure that the turbidity sensor 16 rapidly detects the color change in the accommodating space. When volatile chlorine dioxide gas for sterilization is contained in the containing space, the chlorine dioxide gas needs to be loaded in the gel substances, and at the moment, the turbidity sensor 16 detects the change of the color of the gel in the containing space to obtain the residual amount of the chlorine dioxide gas; when the accommodating space is filled with raw materials for preparing volatile matters, the color change of liquid or gel in the accommodating space is detected by the turbidity sensor 16 so as to obtain the residual amount of the volatile matters.

For convenience of processing, the bottom cover 10 may be directly made of a transparent material so that the turbidity sensor 16 detects a color change in the accommodating space.

When the accommodating space only stores volatile matters, the storage amount is limited, and the volatile matters need to be frequently replaced by a user during use, so that the volatile matters need to be prepared in real time to obtain a large amount of volatile matters in real time, and at the moment, reactants for preparing the volatile matters need to be isolated in different independent spaces before being activated; in some embodiments, the side of the bottom cover 10 facing away from the inner container 200 of the household appliance cabinet comprises a second chamber 101 for storing a first reactant; the second chamber 101 has a certain depth for storing a first reactant, the second chamber 101 may be configured in any shape, and in some embodiments, the second chamber 101 extends to a side away from the household appliance cabinet inner container 200; since the second chamber 101 is used for accommodating the first reactant, the space outside the second chamber 101 on the bottom cover 10 is used for accommodating the second reactant, i.e. the second chamber 101 is used for separating the two reactants into two spaces.

In some embodiments, the apparatus further comprises a sealing part 102 forming a moving space of the plunger 15, the sealing part 102 is disposed near the second chamber 101, the plunger 15 collides with the isolation structure sealing the second chamber 101 after moving in the sealing part 102 and partially separates the isolation structure from the second chamber 101 (i.e. the isolation structure is still retained on the second chamber 101), so that two reactants in an isolated state in the accommodating space are mixed with each other to generate a volatile for sterilization; at this time, the sealing part 102, the plunger 15 and the sealing member (e.g., a sealing ring fitted on the plunger 15) together form a sealed space to prevent the raw material for preparing volatile or the product of the raw material from flowing out of the sealing part 102. The isolation structure can be a first box body 11, and the fixed connection mode of the first box body 11 and the bottom cover 10 includes but is not limited to detachable connection modes such as clamping, sleeving, screwing, covering and the like; the two are fixedly connected to form an accommodating space for accommodating reactants, and the reactants can be solid or liquid. The sealing part 102 is located near the second chamber 101, and the plunger 15 abuts against the first container 11 after moving a distance in the sealing part 102 to partially separate the first container 11 from the bottom cover 10; in some embodiments, the sealing portion 102 is disposed inside the second chamber 101, and a space for accommodating the first reactant is formed between the sealing portion 102 and the second chamber 101, and the sealing portion 102 extends along the extending direction of the second chamber 101 to the side away from the tank liner 200. The shape and size of the sealing part 102 are similar to those of the top rod 15, and a gap exists between the end of the top rod 15 and the first box body 11 in an initial state, so that the top rod 15 can abut against the first box body 11 after being subjected to an external force by a small movement distance, and a gap is formed between the first box body 11 and the bottom cover 10. In other embodiments, the sealing portion 102 is disposed at the outer peripheral edge (not shown) of the second chamber 101, the shape and size of the sealing portion 102 are similar to those of the lift pin 15, and the sealing portion 102 extends in the extending direction of the second chamber 101; the end of the top bar 15 has a gap with the outer contour of the first container 11 initially, and after the top bar 15 is stressed, the end of the top bar 15 abuts against the outer contour of the first container 11, so that the first container 11 is partially separated from the bottom cover 10 after being stressed. In order to make the top rod 15 easily contact with and lift up the first box 11, at this time, a contact part matching with the top rod 15 may be disposed on the outer contour of the first box 11, so as to lift up the first box 11. In addition, the first container 11 can be a hinge structure or a flip structure, so that the first container 11 initially forms a closed space with the bottom cover 10, when an external force is applied, the first container 11 and the bottom cover 10 form a gap for the reactants to flow in or out, and at this time, the first container 11 is kept on the bottom cover 10, and the measurement accuracy of the turbidity sensor 16 cannot be affected by the falling.

In some embodiments, there is a gap between the first casing 11 and the end of the device for driving the first casing 11 before the household appliance sterilization module is not activated. Specifically, a gap exists between the first container 11 and the top rod 15 for driving the first container 11, that is, after the top rod 15 is driven by a driving force and moves for a certain distance, the end of the top rod 15 will abut against the first container 11 to make the first container 11 partially separate from the bottom cover 10, so as to mix the two reactants; the gap provides a corresponding buffer space for the ejector rod 15, and the household appliance sterilization module 100 is prevented from being accidentally collided to trigger the first box body 11 to jack up. It should be understood that the end of the top bar 15 may initially abut against the first container 11 but the abutting force is not enough to prevent the first container 11 from separating from the bottom cover 10, but in order to prevent the household appliance sterilization module 100 from shaking during transportation and prevent the first container 11 from separating from the bottom cover 10, a gap is preferably formed between the top bar 15 and the first container 11.

In some embodiments, the sealing portion 102 includes a first protrusion (not shown) corresponding to a stop structure, the first protrusion extending along the inner wall of the sealing portion 102 toward the center of the stem 15 to form a sealing portion 102 with a smaller diameter in the sealing portion 102 to accommodate the main body of the stem 15. The end of the jack 15 can be located at the entrance of the sealing part 102 or in the sealing part, when the end of the jack 15 is located at the entrance of the sealing part 102, the end of the jack 15 forms an integral contour with the contour of the bottom cover 10; when the end of the top bar 15 is located in the sealing part 102 and the sealing part 102 includes the first protrusion, the end of the top bar 15 abuts against the first protrusion to provide support for the top bar 15, and at the same time, the first protrusion can prevent the top bar 15 from moving excessively to completely separate the first container 11 from the bottom cover 10; in addition, the household appliance sterilization module can be prevented from being damaged by excessive movement of the ejector rod 15.

Example two

As shown in fig. 1 to 5, a household appliance sterilization module 100 includes a bottom cover structure having a turbidity sensor 16 as in the above embodiments, and further includes: a first cartridge 11 for enclosing a first reactant in the second chamber 101; the top cover 12 is fixedly connected with the bottom cover 10, and an accommodating space for storing a second reactant is formed in the top cover 12 and the first box body 11; a turbidity sensor 16 for detecting a color change in the accommodating space; under the action of external force, the first box body 11 is at least partially separated from the bottom cover 10 to mix the first reactant and the second reactant to generate volatile matters for sterilization; the turbidity sensor 16 detects the color change in the accommodating space to obtain the remaining amount of the volatile matter. In some embodiments, the bottom cover 10 may be ultrasonically welded to the top cover 12; in other embodiments, the bottom cover 10 and the top cover 12 may be fixed by clamping, sleeving, screwing, bonding, or the like, that is, the top cover 12 and the bottom cover 10 may be fixed in a detachable or non-detachable manner, and when non-detachable connection is adopted, the sealing performance of the household appliance sterilization module 100 may be ensured; the top cover 12 stores a second reactant therein; the first box body 11 is used for packaging a first reactant in the second chamber 101, that is, the first box body 11 is combined with the second chamber 101 to prevent the first reactant and the second reactant from flowing before the home appliance sterilization module 100 is started, and the first box body 11 can be initially covered or sleeved on the bottom cover 10 or the first box body 11 is in a flip structure or a hinge structure; the first container 11 is partially separated from the bottom cover 10 by an external force so that the first reactant is mixed with the second reactant and a sterilizing gas is generated to flow out through the vent holes on the top cover 12, it being understood that vent holes may be formed on the bottom cover 10. The external force, which may be provided by a user or other external structure, causes the first container 11 to be partially separated from the bottom cover 10 to allow the second reactant to be mixed with the first reactant.

In order to ensure that the first container 11 is partially separated from the bottom cover 10, the first container 11 further includes a second protrusion 111 protruding from the first container 11, so that the first container 11 is retained on the bottom cover 10 by the second protrusion 111 after the electric home sterilization module is activated, and in particular, when the sealing part 102 is included, the second protrusion 111 is hung on the sealing part 102. Specifically, the second protrusion 111 extends away from the household appliance liner 200 or extends close to the household appliance liner 200, the opening size of the second protrusion 111 is larger than the opening size of the sealing portion 102, and the second protrusion 111 may be in any shape, or the opening size of the second protrusion 111 is smaller than the opening size of the sealing portion 102, and the second protrusion 111 may be in any shape. In some embodiments, the second protrusion 111 extends away from the household appliance liner 200, in which case the opening of the second protrusion 111 is larger than the opening of the sealing portion 102, and the second protrusion 111 initially hangs on the sealing portion 102. In other embodiments, the second protrusion 111 extends toward the side close to the household appliance liner 200, at this time, the opening of the second protrusion 111 is smaller than the opening of the sealing portion 102, and the second protrusion 111 is initially sleeved on the sealing portion 102. When the first container 11 is forced, the first container 11 is lifted, but the first container 11 is still maintained on the bottom cover 10 without falling down due to the second protrusion 111.

In order to control the ventilation amount of the volatile matters in the household appliance sterilization module 100, the household appliance sterilization module further comprises a ventilation film 13, and the ventilation film 13 is hermetically covered on a ventilation part of the household appliance sterilization module, and the ventilation part can be arranged at any position. In some embodiments, the air permeable membrane 13 is hermetically covered on the vent hole of the top cover 12 along the contour of the top cover 12, and the vent hole can be arranged in any shape and any position; the setting of ventilated membrane 13 along the profile of top cap 12 has been promptly guaranteed the leakproofness between ventilated membrane 13 and the top cap 12, prevents to have the gap between ventilated membrane 13 and the top cap 12, leads to the volatile substance not to get into the household electrical appliances inner bag promptly through ventilated membrane 13. The air permeable membrane 13 is made of air permeable and water impermeable material, such as PE membrane, PUW membrane, silica gel, and non-woven fabric. To prevent the outflow of reactants and/or reactant products, in this embodiment, processing is convenient and gas and water permeation is ensured. Because the breathable film is soft and easy to damage, in some embodiments, the second case 14 is further included, and the breathable film 13 is pressed on the ventilation portion of the household appliance sterilization module 100 by the second case 14. In some embodiments, when the top cover 12 includes a plurality of vent holes, the second container 14 presses the gas-permeable membrane 13 onto the top cover 12, and at this time, the second container 14, the top cover 12 and the bottom cover 10 form a consistent overall contour, which can ensure the integrity and the aesthetic property of the household appliance sterilization module; in addition, the second container 14 presses the air permeable membrane 13 on the top cover 12, which can prevent the air permeable membrane 13 from decreasing in sealing property after long-term use and forming a gap with the top cover 12. The second box 14 further comprises a plurality of air holes to facilitate air entering the household appliance box. The turbidity sensor 16 is accommodated in the first chamber 103 of the bottom cover 10 close to the household appliance inner container 200 side; the first chamber 103 is shaped and sized according to the size and shape of the turbidity sensor 16 so that the turbidity sensor 16 can be stably placed in the first chamber 103. The bottom cover 10 is fixedly connected with the top cover 12, and a containing cavity is formed between the bottom cover 10 and the top cover 12 to contain reactants, before the first reactant and the second reactant are not mixed, the second reactant is stored in the top cover 12, and the second reactant and the first reactant are separated in two independent spaces through an isolation structure (for example, through separately arranging a box body cover in the second cavity 101).

Specifically, the gas permeable membrane 13 is made of a gas permeable and water impermeable material, which may be a gas permeable membrane (such as a PE membrane, a PUW membrane, etc.), a silica gel, a non-woven fabric, etc., on one hand, which is capable of facilitating the gas of the volatile matter to pass through, and on the other hand, which is capable of blocking the liquid from overflowing the household appliance sterilization module 100, and in addition, the gas permeable membrane 13 may prevent the dust outside the sterilization module 100 from entering the household appliance sterilization module. Because different breathable films 13 have different breathable rates, the breathable films 13 can be selected according to the volume of the household appliance, so as to adjust the breathable amount of the volatile matters in the same time period.

In some embodiments, the first chamber 103 is located remotely from the second chamber 101 such that when the second reactant is mixed with the first reactant, the turbidity sensor 16 is in a region of uniform concentration of the mixed reactants; specifically, since the turbidity sensor 16 is disposed away from the second chamber 101 storing the first reactant, when the second reactant is mixed with the first reactant, the liquid or gel in the second chamber 101 and the space near the second chamber 101 has a darker color, and the color far from the second chamber 101 is weaker; after the sterilizing gas is diffused for a period of time, the color of the liquid or gel in the accommodating space tends to be balanced. Therefore, in order to ensure the accuracy of the measured concentration of the sterilizing gas, the turbidity sensor 16 is located remotely from the second chamber 101.

The first reactant and the second reactant can be any raw materials capable of producing a gas for disinfection, and in some embodiments, the second reactant is an acidic liquid, such as hypochlorous acid and/or hydrochloric acid, and the first reactant is a solid or a solid powder (in order to mix the first reactant with the second reactant after the home sterilization module 100 is activated, the solid or solid powder fills the second chamber 101 as much as possible or the liquid level of the second reactant reaches the position of the chamber where the first reactant is located), and the fixed powder is generally a chlorate or chlorite powder, so as to mix to generate chlorine dioxide gas; in other embodiments, the first reactant may be provided as an acidic liquid and the second reactant may be provided as a solid powder, which facilitates the mixing of the liquid reactant flowing from the second chamber 101 with the second reactant. In other embodiments, the first reactant and the second reactant may both be liquids, and only the reaction of the two reactants to generate the sterilizing gas is required. It should be noted that the substance formed by the reaction of the first reactant and the second reactant preferably does not contain a precipitate, so as to prevent the detection accuracy of the turbidity sensor 16 from being affected when the turbidity sensor 16 is included.

It should be understood that the sterilizing gas in this embodiment is a gas having a distinct color, such as chlorine dioxide gas, which is yellowish green at a high concentration and fades in color with a distinct difference in color when the concentration becomes lighter. At this time, the change in the color of the sterilizing gas is detected by the turbidity sensor 16 to reflect the concentration of the sterilizing gas (i.e., whether the remaining amount of the sterilizing gas is sufficient).

The bottom cover 10 includes a sealing portion 102 for receiving the lift pin 15, at this time, the lift pin 15 is directly mounted on the bottom cover 10, and the lift pin 15 moves in the sealing portion 102 to partially separate the first container 11 from the bottom cover 10; in some embodiments, the bottom cover 10 may be ultrasonically welded to the top cover 12; in other embodiments, the bottom cover 10 and the top cover 12 may be fixed by clamping, sleeving, screwing, bonding, or the like, that is, the top cover 12 and the bottom cover 10 may be fixed by detachable connection or non-detachable connection, and when non-detachable connection is adopted, the sealing performance of the household appliance sterilization module 100 may be ensured. The closed space formed by the bottom cover 10 and the first box body 11 is used for storing a first reactant, and the first reactant is solid or liquid; the first box body 11 and the top cover 12 form a closed space for storing a second reactant, wherein the second reactant is liquid or solid powder; the ejector pin 15 ejects the first box body 11 to mix the first reactant and the second reactant to generate the sterilizing gas. In other embodiments, the bottom cover 10 includes only a sealing portion 102, and in this case, a boss is provided on the inner container of the home appliance, and the boss is movable within the sealing portion 102 to partially separate the first container 11 from the bottom cover 10.
