The present disclosure relates to a method for controlling a laundry dryer, the method comprising: a steam supplying step for supplying steam to a heat exchange unit; a cleaning step for controlling a cleaning unit after the steam supplying step, and thereby spraying cleaning water to the heat exchange unit according to preset spraying criteria; and a drying step for drying the heat exchange unit after the cleaning step. The present invention has the effect of eliminating and sterilizing foreign substances, microorganisms, and the like present in the heat exchange unit.

The invention relates to method of filling a medical washer/disinfector. A desired pump speed of a circulation pump is determined. A predefined filling level associated with the desired pump speed is identified. Liquid is fed into a washing chamber while the circulation pump is running at less than said desired pump speed. While the liquid is continued to be fed so that the liquid level rises, the pump speed is increased based on the rising liquid level until said desired pump speed is reached. When the pump is running at said desired pump speed, it is detected when the liquid has been filled to the predefined filling level, and upon such detection the feeding of the liquid into the washing chamber is interrupted. Then invention also relates to a method of operating a medical washer/disinfector, a control unit and a medical washer/disinfector.

Sanitizing devices may be configured to emit sanitizing light into an environment in order to sanitize air, objects, and/or surfaces in the environment. The sanitizing light may be of a wavelength, or set of wavelengths, that deactivates, kills, or neutralizes, pathogens such as bacteria and viruses but, is not harmful to human or animal tissue. The sanitizing devices may be configured to be able to communicate with each other and/or a user over, for example, the Internet, a wireless communication network, a mesh network, and/or a near-field communication protocol in order to, for example, provide operation information and/or receive operation instructions.

A cleaning unit for cleaning a housing of a medical imaging apparatus surrounding a patient receiving area, including at least one cleaning element, wherein the at least one cleaning element has an annular carrier structure, and a diameter of the cleaning element comprises at least one value of a diameter of the housing surrounding the patient receiving area.

Plug for high-pressure processing machines with a bag, comprising a duct for the passage of a pressure-transmitting fluid to the bag, another duct for filling and emptying of a product to be pressurized and a valve. The plug is further provided with a rod for opening and closing the valve. Said rod is located in the duct for the product and has its own inner duct joined to a cleaning agent chamber for the passage of the cleaning agent through the product duct. The invention also relates to a machine incorporating said plug and a method for the processing of pumpable substances. Hygienic design and very high pressure sealing requirements are met by the invention.

The present invention is a transportable autonomous robotic merchandise dispensing drive thru wherein merchandise is loaded into said facility and dispensed to a customer through an ordering app downloaded on a mobile device or ordered at a facility site. Said drive thru facility is unmanned and completely computer and robotically operated utilizing no humans within said facility. Said facility is operated via computer processor and requires internet but no utility connections such as water, sewage, electric or gas. The current invention has a three part sanitizing system: interiorly, in each serving compartment and at each exterior touchscreen.

A shopping cart washing assembly includes a tunnel that is positionable in a location which employs shopping carts wherein the tunnel is configured to have the shopping carts moved through the tunnel. A plurality of lower spray nozzles and a plurality of upper spray nozzles is each integrated into the tunnel to spray a liquid for washing shopping carts. A first drive unit and a second drive unit is each movably integrated into the tunnel. A plurality of grappling units each extends between the first drive unit and the second drive unit. Each of the grapping units engages a handle of a respective shopping cart to transport the respective shopping cart through the tunnel.

A sanitary washing device includes a nozzle, a casing, an illuminator, and a controller. The nozzle discharges water toward a private part of a user in a state of the nozzle is advanced into a toilet. The casing includes a nozzle storage part configured to store an entirety of the nozzle in a state of the nozzle is retracted. The illuminator irradiates sterilizing light into the nozzle storage part. The sterilizing light has a sterilizing action. The controller controls the illuminator. The controller includes a first irradiation mode of causing sterilizing light irradiated from the illuminator to be irradiated toward an outer circumferential surface of the nozzle. The controller includes a second irradiation mode of causing sterilizing light irradiated from the same illuminator as the first irradiation mode to be irradiated toward an inner wall of the nozzle storage part.

A method and apparatus for sterilizing medical instruments, including a device for controlling specific humidity, SH, of flow of a gas or gas mixture. The device includes a tank for storing a volume of water. The tank has an inflow port for receiving the gas or gas mixture, and an outflow port for allowing humidified gas or gas mixture at the required SH to exit the tank. The temperature of the water and/or the pressure of the supplied gas or gas mixture are controlled for the required SH.

A reusable apparatus, such as a medical instrument or tool, is decontaminated by applying pressure waves with direct contact of the pressure wave applicator to the reusable apparatus in an open bath in a sufficient dosage to remove contamination but without adversely affecting the ability to reuse the apparatus.
