Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to water supply to a housing during presoak cleaning and shower rinsing.

<Prior art> Equipment that automatically cleans and sterilizes instruments contaminated with dirt and bacteria is used for the purpose of preventing nosocomial infections by preventing bacteria and viruses from being taken out of the surgical department, surrounding area, or hospital ward. be done.

This device normally performs cleaning and sterilization operations in the order of presoak cleaning, shower rinsing, and sterilization.
Generally, detergent is used during pre-soak cleaning to make it easier to remove dirt from the object to be cleaned, but if water is supplied to the case from the same water inlet as used for shower rinsing, the water and detergent will diffuse due to the shower effect and foam will form. becomes large, often causing malfunctions in detecting the water level inside the housing. In other words, the water level is insufficient and the object to be cleaned is not completely immersed. Further, there were drawbacks such as affecting the rinsing effect in the next step of shower rinsing.

<Purpose> In view of these points, the present invention aims to provide an automatic cleaning/sterilization device that suppresses foaming during pre-soak cleaning and performs the desired pre-soak cleaning and shower rinsing.

<Example> The present invention will be described below using an example with reference to the drawings.

Figure 1 is a structural diagram of the case of the automatic cleaning/sterilization device. 1 is the door for taking out and putting the basket containing the items to be cleaned in the can, and 2 is the door for cleaning from the door when door 1 is closed. A door gasket that prevents leakage of water and steam, 3 a housing that holds cleaning water and steam, 4 a detergent injection case that stores detergent and injects the detergent into the housing 3 by closing the door 1, and 5 a housing that holds cleaning water and steam; A drainboard frame on which the basket is placed, 6 a drain filter for removing dust and the like when washing water is drained, and 7 an electrode for detecting the upper limit water level in the housing 3. Reference numeral 9 denotes a water supply port through which the electromagnetic valve 12 opens during pre-soak cleaning and injects water sent by the pump 11 into the case 3. On the front side thereof, there is a water supply port along the inner surface of the case 3 as shown in Fig. 2. A guide plate 10 is provided so that water can be supplied thereto. 8 is a shower nozzle, and during shower rinsing, a solenoid valve 13 opens and water sent by a pump 11 is sprayed to rinse the object to be washed.

In this way, during presoak cleaning, water is supplied from the water supply port 9 without a shower nozzle, and the cleaning water is filled along the inner surface of the housing 3, so that the detergent dissolves in the cleaning water without foaming, and the can is filled with water. There is no effect on the electrode 7 that detects the water level of the body, and the object to be cleaned can be reliably immersed.

<Effects> According to the present invention as described above, the water supply ports for pre-soak cleaning and shower rinse are provided separately, so foaming during pre-soak cleaning using detergent is suppressed and the desired results are achieved. Pre-soak cleaning and shower rinsing are now possible.

Claims (1)

[Scope of Claim for Utility Model Registration] A pre-soak water inlet and a shower water inlet in a device that automatically cleans and sterilizes objects to be cleaned by introducing cleaning water and steam into a housing containing the objects to be cleaned. A valve-controlled pre-soaking water supply pipe and a shower water supply pipe are connected to the housing so that they are separated from each other at the upper part of the housing, and the water discharged from the water supply port is provided in front of the pre-soaking water supply port. An automatic cleaning and sterilization device comprising: a guide plate for guiding detergent to flow along the inner wall of the housing; and means for injecting detergent into the housing during pre-soak cleaning.
