The utility model provides a high-efficiency energy-saving ice-making device, which relates to the technical field of ice making and comprises a base, a main shell is fixedly connected onto the base, an auxiliary shell is fixedly connected onto the base, a high-efficiency compressor is mounted and connected inside the main shell, a condenser is arranged on one side of the high-efficiency compressor, and a condenser is arranged on the other side of the high-efficiency compressor. And a heat exchanger is mounted and connected to the rear side of the condenser. The motor drives the driving shaft to rotate to drive the moving block and the right-angle water outlet piece to move, so that each partition groove in the multi-groove partition plate can store water equivalently, uniformly distributed water flow can be in full contact with an evaporator, and the time for converting water into ice is greatly shortened; the pushing block is pushed to move through the electric cylinder, the protruding plate at one end of the multi-groove partition plate is in linkage with the cover plate, ice blocks are smoothly pushed into the trapezoidal collecting bin, the gravity principle is utilized in the design of the trapezoidal bin, the ice blocks naturally slide down and accumulate, and blockage and disorder of the ice blocks in the collecting process are avoided.

The application discloses a bearing retainer with slot type through cavities, each cross beam of the bearing retainer is provided with two slot type through cavities which are distributed along the radial direction of the retainer body; one slot type through cavity is used for connecting the converging area on one side of the cross beam with the diverging area on the other side, and the other slot type through cavity is used for connecting the diverging area on one side of the cross beam with the converging area on the other side. The bearing retainer can realize the stable lubricating oil flow self-enhancement effect near the friction surface through the slot type through cavities, effectively reduces the extrusion flow and the oil film cavitation degree near the friction surface between the rolling body and the retainer, makes the lubricating oil near the friction surface more efficient, reduces the friction resistance and the wear condition, improves the heat dissipation capacity of the bearing, and collects the bearing abrasion through the slot type through cavities, avoids the abrasion from entering the contact area of the friction surface in the flowing process, and makes the bearing appear more serious wear problems.

The present application relates to the cultivation technology field of Paeonia lactiflora, and specifically provides a commercial full-promoting cultivation technology of Paeonia lactiflora. The present application provides a method for Paeonia lactiflora to bloom in off-season. After dwarfing treatment at the Paeonia lactiflora budding stage in April, the swollen flower buds are removed, and the Paeonia lactiflora is subjected to gradient low-temperature treatment in August. The conditions of the gradient low-temperature treatment are as follows: the temperature is controlled at 5-7 DEG C in the first week; the temperature is controlled at 1-5 DEG C in the second week; the temperature is controlled at 0-5 DEG C in the third week; the temperature is controlled at -3-8 DEG C in the fourth week; the temperature is controlled at -10 DEG C in the fifth week; the temperature is controlled at -3-5 DEG C in the sixth week; the temperature is controlled at 0-5 DEG C in the seventh to eleventh weeks, and the Paeonia lactiflora is harvested in December. The method provided by the present application can obtain Paeonia lactiflora fresh flowers in winter, effectively increases the types of fresh flowers in winter, and enriches the winter flower market.

The utility model provides a kettle type electric water heater heating pipe group and an electric water heater, the heating pipe group comprises a plurality of heating pipes, and a kettle type heating space is defined by the plurality of heating pipes; part of the heating pipes are arranged at the kettle bottom of the kettle-shaped heating space to form a kettle bottom heating area; part of the heating pipes are arranged on the kettle wall of the kettle-shaped heating space to form a kettle wall heating area; the kettle bottom heating area is arranged on a convective heat exchange path of the electric water heater, and the kettle wall heating area encircles the convective heat exchange path; the convective heat exchange path is located between a water inlet and a water outlet of the electric water heater, and on the convective heat exchange path, hot water tends to flow to the water outlet, and cold water tends to flow to the water inlet.
