The cooking range a furnace body, a furnace head and a water tank, wherein the furnace body is combined by an inner furnace wall and an outer furnace wall; a hollow region surrounded by the inner furnace wall is a hearth; a plurality of tubular fire bars are uniformly arranged below the hearth at intervals in the furnace body; the furnace head comprises an outer furnace ring, an inner furnace ring and a pot body supporting ring; the lower end of the inner furnace ring is connected to the inner furnace wall; the lower end of the pot body supporting ring is connected to the outer furnace wall; a cavity among the inner wall furnace, the outer wall furnace and the furnace head is a heating cavity; a coil surrounding the hearth is arranged in the heating cavity; a steam pipe communicating with the top of the heating cavity is arranged in the upper part of the water tank; a water outlet pipe communicating with the bottom of the heating cavity is arranged in the lower part of the water tank; a gas outlet pipe is arranged on the top of the water tank; a water inlet is formed between the steam pipe and the water outlet pipe on the water tank; and a float ball water inlet valve is arranged on the water inlet. The cooking range provided by the invention realizes efficient recovery of smoke heat and automatic control of water inflow in a stove using process.

The invention discloses an anti-freeze ultra-low temperature refrigeration system and its use method. The anti-freeze ultra-low temperature refrigeration system includes a first refrigeration assembly and a second refrigeration assembly, and both the first refrigeration assembly and the second refrigeration assembly include a compressor , a condenser, an evaporator, and a capillary tube, the evaporator of the first refrigeration assembly and the condenser of the second refrigeration assembly are arranged correspondingly; the antifreeze ultra-low temperature refrigeration system also includes a heating assembly, and the heating The assembly is arranged on the first refrigeration assembly; in the present invention, the capillary of the second refrigeration assembly is preheated through the heating assembly communicated with the first refrigeration assembly, so as to avoid low temperature of lubricating oil in the capillary Blockage caused by precipitation and solidification.

The invention relates to a flat freezing plate, comprising: an end plate, on which an upper through hole and a lower through hole are arranged; an end sealing plate, on which a vertical connection hole is arranged on the end sealing plate; a number of The middle sealing plate is provided with an upper horizontal connecting hole and a lower horizontal connecting hole; a plate assembly, the plate assembly is composed of several sub-plates connected, each of which is provided with an upper channel and a lower channel. The invention realizes the effective reorganization of the channel in the flat freezing plate, fully guarantees the heat exchange between the goods on the surface of the whole flat freezing plate and the refrigerant; the heat exchange between the goods and the refrigerant is sufficient, the freezing effect of the goods is good, the freezing efficiency is high, and the refrigerant Charge less.

The invention discloses an automatic dedusting device for an outdoor unit of an air conditioner, and relates to the technical field of cleaning and dedusting heat exchangers for air conditioners, including an outdoor machine cover, slide rails, a mobile cleaner, a swing arm, a water guide pipe, a connecting pipe, a water pump, Steering gear and sewage tank; slide rails are connected to both sides of the outdoor machine cover, and sewage tanks are connected to the bottom of the slide rails; both ends of the mobile cleaner are connected to the slide rails, the connecting pipe is connected to the mobile cleaner, and the water guide pipe The first end is connected with the connecting pipe, and the second end of the water guide pipe is connected with the water pump; the mobile cleaner is also movably connected with the swing arm, and the second end of the swing arm is connected with the steering gear. The working mode of the present invention includes the normal working mode of the heat exchanger when the dust removing device is not started and the automatic dust removing working mode of the heat exchanger when the dust removing device is started. The invention can remove the granular dust and catkin fiber accumulated on the windward surface of the heat exchanger together, and significantly improve the dust removal effect on the surface of the heat exchanger of the outdoor unit.

The invention relates to the technical field of electronic products, and discloses a heat dissipation and dustproof device for projectors that is beneficial to the principle of centrifugal force. Air intake holes, the two sides of the inner casing are provided with air outlet holes, the inside of the outer casing is fixedly connected with a suction fan, the top of the suction fan is fixedly connected with an air inlet channel, and the top of the air inlet channel is fixed An adsorption layer is connected, the outside of the adsorption layer is fixedly connected with an air inlet partition, the two sides of the suction fan are fixedly connected with an air outlet, and the outside of the air outlet is fixedly connected with a liquid storage box, and the liquid storage The inside of the box is fixedly connected with a partition net, which can achieve the effect of preliminary dust removal through the cooperation of the air inlet net and the adsorption layer, and prevent the fan from inhaling large particles of dust in the air, so as to remove dust from the air entering the projector. Effect.
