Household technologies

In this section, antiquities related to work in the household are collected, primarily devices for washing and ironing, sewing, cleaning, food preparation and storage, as well as body care. The objects come mainly from the interwar period and the second half of the twentieth century.
The most interesting exhibits include:
- a New World stove, produced ca. 1930 by Radiation Ltd. (Great Britain)
- a "Husch - Husch" laundry device, made in Germany ca. 1900.
- an ice refrigerator Hochner, produced in Austria in the late nineteenth/early twentieth century.
- "Frequenta" electrotherapy device, produced in the years 1928-1929 by Velmag Leipzig (Germany)
- "Protos" vacuum cleaner, produced in the 1930s by Siemens-Schuckert (Germany)
- Gamma II vacuum cleaner, produced in 1960 by the Rzeszów Household Equipment Factory

"Husch – Husch" laundry device, Germany, ca. 1900.
In practice it is a manual washing machine. It consists of two cups and a metal rod. Both cups are open at the bottom. The smaller, bottom one is inserted into the second, larger, and fixed centrally with a screw to a spring-mounted disc. Upper cup, the larger one, has a vertical sheetplate sleeve on the top with a rigidly embedded rod. Under the upper end of the rod, there is a small hole in a horizontal channel, and under the hole there is a circumferential indentation on the rod – to tie a loop of string.
The device was used for washing in a bucket or a tub, eliminating some effort necessary for hand washing. After immersion in a washing tube with soap water and laundry, the rod was pushed down with a series of repetitive movements, causing insertion of the bottom cup into the upper one, then pressure was released, allowing the bottom cup to automatically slide out to the starting position, due to a spring. These movements caused laundry mixing. The device performed functions similar to those of the manual or electric rotary washing machine rotor. It was designed mainly for households or small laundry services, whereas rotary hand washing machines, rare at that time, were complex, larger and utilised more in hotel laundry rooms and larger services; these were devices eliminated during the twentieth century by household and industrial electric washing machine. The "Husch-Husch" brand name came probably from the sound produced during operation.

Gamma II vacuum cleaner, Poland, 1960.
It is a small and lightweight household vacuum cleaner with electric drive and an equipment set: a flexible hose (wire and cloth, with plastic ends, one to attach by pushing into the body, the other to the attach the pipes), pipes (from ginger-red plastic) and a set of brushes (mounted on the pipe; brushes in various shapes, most of plastic and a wooden one, with artificial hair). The body of the vacuum cleaner has the shape of a horizontal cylinder made of a blue mottled plastic, closed at both ends with black plastic cups; one is mounted with screws, and under it there is an electric motor. The second cup is mounted on brackets, and underneath there is a fabric bag for garbage sucked with the air current generated by the motor-driven fan – through an opening in the cover, suitable for hose mounting. It has been a standard technical solution for vacuum cleaners since the nineteenth century to this day. The form of the device is characteristic of design and material changes at the time of creation: the cylindrical body shape replicates pre-war patterns, but the material (plastic replacing previously used sheet metal, e.g. from the earlier model, gamma) is a new trend of approx. 1960. Polish-designed and produced, it was widespread in the era (RFSG: later "Zelmer").
