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 mounting structure for a sterilization module of a home appliance, such as a refrigerator, a freezer, or the like, which stores food for a long time and needs sterilization. The mounting structure comprises a bottom cover 10, which is arranged on the household appliance inner container 200 and is used for being fixedly connected with a top cover 12 and forming corresponding accommodating spaces inside the top cover 12 and the bottom cover 10, wherein the bottom cover 10 and the top cover 12 can be welded by ultrasonic waves; in addition, the bottom cover 10 and the top cover 12 can be fixed by clamping, sleeving, screwing, bonding and other modes, namely the fixed connection mode of the top cover 12 and the bottom cover 10 comprises detachable connection and non-detachable connection, and when the non-detachable connection is adopted, the sealing performance of the household appliance sterilization module can be ensured; the bottom cover 10 includes a first chamber 101 for accommodating a first reactant, the first chamber 101 has a certain depth for storing the first reactant, the first chamber 101 may be configured in any shape, and in some embodiments, the first chamber 101 extends to the side away from the inner container of the appliance casing. The mounting structure further comprises a first box body 11 which is fixedly connected with the bottom cover 10; before the household appliance sterilization module 100 is activated, the first box body 11 encloses the first reactant in the first chamber 101 to prevent the first reactant from flowing out of the first chamber 101. Specifically, the first container 11 is detachably connected to the bottom cover 10, the detachable connection is different from the fixed connection between the bottom cover 10 and the top cover 12, and the fixed connection between the bottom cover 10 and the first container is easily removed under the action of external force. The space formed by the top cover 12 and the first case 11 contains the second reactant, i.e. the second reactant is sealed in the sealed space formed by the bottom cover 10 and the top cover 12, meanwhile, the first case 11 separates the first reactant from the second reactant in two independent spaces, i.e. before the home sterilization module 100 is used, the first reactant exists in the sealed space formed by the bottom cover 10 and the first case 11, and the second reactant exists in the sealed space formed by the bottom cover 10, the first case 11 and the top cover 12. After the household appliance sterilization module 100 is activated, the first box body 11 is at least partially separated from the bottom cover 10 under the action of external force, so that the first reactant and the second reactant are mixed to generate volatile matters for sterilization; it should be understood that "at least partially detached" means that the first container 11 is partially detached from the bottom cover 10, i.e., there is a gap between the first container 11 and the bottom cover 10, but the first container 11 is not detached from the bottom cover 10; the term "at least partially detached" may also mean that the first container 11 is completely detached from the bottom cover 10, i.e. the first container 11 falls into the space formed by the bottom cover 10 and the top cover 12. In some embodiments, the first container 11 is lifted by an external force and then falls off the bottom cover 10, so that the second reactant is rapidly mixed with the first reactant. In other embodiments, the first casing 11 forms a gap with the first chamber 101 under the action of an external force, so that the first reactant and the second reactant are mixed. Specifically, under the action of the external force, the first container 11 moves away from the bottom cover 10 and forms a gap with the first chamber 101, and the gap can allow the second reactant in the top cover 12 to flow into the first chamber 101 and/or the first reactant in the first chamber 101 to flow out of the first chamber 101 to mix with the second reactant, it should be noted that although the first container 11 moves away from the bottom cover 10, it is not completely separated from the bottom cover 10, i.e. the first container 11 still keeps connected with the bottom cover 10. The first container 11 forms a gap with the first cavity 101 under the action of external force, and in some embodiments, the first container 11 is hung in the first cavity 101 of the bottom cover 10 under the action of external force. That is, when the first container 11 is acted by external force, the first container 11 will move relative to the bottom cover 10, but the first container 11 will not be separated from the bottom cover 10 and still be attached to the bottom cover 10. This embodiment is applicable to the condition that needs detect in the top cap after the reaction, prevents that first box body 11 from falling the back influence and to the appraisal of first reactant, the second reactant result after the reaction or the appraisal of the state after the reaction.

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 first reactant and the second reactant can be any substance that can combine to generate chlorine dioxide, and the state of the substance is not limited, such as: solid, solid powder and liquid.

In other embodiments, the sealing portion 102 is disposed at the peripheral edge (not shown) of the first chamber 101, the shape and size of the sealing portion 102 are similar to the shape and size of the rod 15, and the sealing portion 102 extends toward the extending direction of the first 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.

The size of the sealing portion needs to be able to accommodate the top rod 15, the end of the top rod 15 accommodated in the sealing portion keeps a distance from the first box 11 in an initial state, and after the top rod 15 moves towards the first box 11, the end of the top rod 15 abuts against the first box 11 so that the first box 11 is at least partially separated from the bottom cover 10. The end of the top rod 15 has a gap with the first container 11 in the initial state, the gap is generally set between 2mm-8mm, so that the top rod 15 can abut against the first container 11 after being subjected to an external force by a small distance, and a gap is formed between the first container 11 and the bottom cover 10.

In order to ensure that the first box body 11 does not fall, the first box body 11 includes a first protrusion 111, the first protrusion 111 extends toward the side departing from the household appliance inner container 200 or toward the side close to the household appliance inner container 200, and the first protrusion 111 is hung on or sleeved on the sealing portion 102 before and after the household appliance sterilization module 100 is started. The opening size of the first protrusion 111 is larger than the opening size of the sealing part 102 and the first protrusion 111 may be in any shape or the opening size of the first protrusion 111 is smaller than the opening size of the sealing part 102 and the first protrusion 111 may be in any shape. In some embodiments, the first protrusion 111 extends away from the household appliance liner 200, and the opening of the first protrusion 111 is larger than the opening of the sealing portion 102, and the first protrusion 111 initially hangs on the sealing portion 102. In other embodiments, the first protrusion 111 extends toward the side close to the household appliance liner 200, at this time, the opening of the first protrusion 111 is smaller than the opening of the sealing portion 102, and the first protrusion 111 is initially sleeved on the sealing portion 102. When the first container 11 is stressed, the first container 11 is lifted, but the first container 11 still can be kept on the bottom cover 10 and will not fall down due to the existence of the first protrusion 111, and at this time, the reactant can slowly react through the gap between the first container 11 and the bottom cover 10; or when the home appliance sterilization module includes the turbidity sensor 16, the first container 11 is prevented from falling to affect the detection accuracy of the turbidity sensor.

In some embodiments, in order to make the first container 11 form a gap with the bottom cover 10 after being stressed, the first container 11 can be a flip structure disposed on the bottom cover 10, and the flip structure is initially sealed with the bottom cover 10, and the top rod 15 pushes up the flip structure to mix the second reactant with the first reactant.
