Description

Condensate collector for flue pipes of gas appliances

technical field

The utility model relates to a condensing gas heating water heater or a gas instant water heater. the

Background technique

Existing condensing gas heating water heaters or gas instant water heaters usually have a smoke exhaust device, which is mainly used as a passage for the flue gas after secondary heat exchange in the main heat exchanger, through which the flue gas is finally led to At the smoke exhaust port, it is discharged to the outside through the inner sleeve of the coaxial smoke pipe. the

Due to the influence of the outdoor environment, the smoke exhaust device used in the existing condensing gas heating water heater, when it rains, the rainwater will enter through the air inlet hole of the coaxial smoke pipe and pour into the furnace; sometimes the inner layer of the smoke exhaust Condensation will also occur in the pipe and flow back into the furnace through the coaxial smoke pipe. the

Rainwater or condensed water entering the furnace directly corrodes the main heat exchanger, seriously affecting the heat exchange efficiency and service life of the main heat exchanger. the

Contents of the invention

The purpose of this utility model is to design a condensed water collecting device for the smoke pipe of a gas appliance, which can solve the problem that the rainwater or condensed water of the smoke pipe is poured into the furnace. the

The technical scheme of the utility model is:

A condensed water collection device for the smoke pipe of a gas appliance, comprising a water receiving tray and a water receiving pipe, the water receiving tray has a connecting ring and a tray, the inner diameter of the connecting ring is adapted to the exhaust pipe end of the gas appliance, The outlet end of the exhaust pipe of the gas appliance can be inserted into the inner hole of the connecting ring, and the outer diameter of the connecting ring is suitable for the mouth end of the smoke exhaust pipe, so that the mouth end of the exhaust pipe can be inserted into the connecting ring for connection, and the middle part of the tray has a perforation , the outer edge of the tray has a water-retaining edge, and one end of the connecting ring is connected to the edge in the middle of the tray; the connecting ring, the tray and the water-retaining edge form a water-receiving ring groove, and the water-retaining edge has a drain port and is connected to a drain pipe joint ; One end of the water receiving pipe is connected to the drain pipe joint of the water receiving tray.

When in use, use the utility model to connect the smoke exhaust device of the condensing gas heating water heater with the smoke exhaust pipe: insert the connecting ring sleeve of the utility model into the exhaust pipe mouth of the gas appliance (make the water ring groove upward) , so that the mouth end of the smoke exhaust pipe is inserted into the connecting ring of the utility model, that is, the smoke exhaust pipe is connected with the exhaust pipe mouth end of the gas appliance through the connecting ring of the utility model, and the other end of the water receiving pipe of the utility model is connected onto the drip tray. the

When there is rainwater or condensed water flowing backwards on the smoke exhaust pipe, the returning rainwater or condensed water is intercepted on the tray of the utility model and discharged from the water receiving pipe, which effectively prevents the rainwater or condensed water from the exhaust of the gas appliance The problem that the nozzle is poured into the furnace. the

The features of this utility model are:

1. The utility model can effectively prevent rainwater or condensed water from being poured into the furnace from the exhaust pipe of the gas appliance;

2. The utility model has the advantages of simple structure and convenient use.

Detailed ways

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a condensed water collection device for a smoke pipe of a gas appliance includes a water receiving tray 1 and a water receiving pipe 2, the water receiving tray 1 has a connecting ring 11 and a tray 12, connected The inner diameter of the ring 11 is compatible with the exhaust pipe mouth end 3 of the gas appliance, so that the exhaust pipe mouth end 3 of the gas appliance can be inserted into the inner hole of the connecting ring 11, and the outer diameter of the connecting ring 11 is matched with the exhaust pipe mouth end. 4 phase matching, so that the mouth end of the smoke exhaust pipe 4 can be inserted into the connecting ring 11 for connection. The middle part of the tray 12 has a perforation, and the outer edge of the tray 12 has a water retaining edge 13. One end of the connecting ring 11 is connected to the middle part of the tray 12 The perforated edge; the connecting ring 11, the tray 12 and the water retaining edge 13 constitute the water receiving ring groove 10, and the water retaining edge 13 has a drain port and is connected to the drain pipe joint 14; one end of the water receiving pipe 2 is connected to the drain of the water receiving tray 1 on the pipe joint 14. the

Referring to Fig. 4, as an application example of the present utility model, first insert the connecting ring 11 of the present utility model into the exhaust pipe mouth end 3 of the gas appliance (making the water receiving ring groove 10 upward), and then insert the exhaust pipe 40 4 sets of smoke exhaust pipe mouth ends are inserted on the connecting ring 11 of the present utility model, so that the smoke exhaust pipe 40 is connected with the exhaust pipe mouth end 3 of the gas water heater 6 through the connecting ring 11 of the present utility model, and exhaust The nozzle end 3 is connected to the fan 5 exhaust nozzle of the gas water heater 6, and the other end of the water receiving pipe 2 of the present utility model is connected to the water receiving tray (not shown). the

When there is rainwater or condensed water pouring back on the smoke exhaust pipe 40, the rainwater or condensed water that flows back is intercepted on the tray 11 of the present utility model and discharged from the water receiving pipe 2, which effectively prevents rainwater or condensed water from being heated by the gas. The problem that the exhaust nozzle 3 of the water heater 6 is poured into the furnace. the
