Abstract
The utility model discloses a condensed water anti-clogging safety control device for a condensing type gas water heater, which is arranged on a condensed water tank. The utility model is characterized in that a water level safety control device is electrically connected with the control device for a condensing type gas water heater. Th ea water level safety control device is composed of a floating ball in the condensed water tank and a microswitch arranged on the upper part of the floating ball; the microswitch is electrically connected with the control device for the condensing type gas water heater; the safety control device can also be composed of a water level inductor in the condensed water tank. The utility model has the advantages of simple structure, safe use assurance, etc.
Description
Technical field
The utility model relates to a kind of condensing type water heater technical field, more particularly relates to a kind of condensing type water heater condensed water and collects safety control.
Background technology
The condensed type combustion gas fast water heater receives increasing concern owing to it has than the high characteristics more than 15% of the general gas fast water heater thermal efficiency, and the condensed type combustion gas fast water heater is owing in use can produce the condensed water that contains corrosion component, this condensed water to environment and water heater can cause certain pollution and and corrosion, therefore the collection emission problem that adopts condensed water collecting device to solve condensed water is necessary.The condensed water collecting device of prior art has the condensed water of employing collector groove, the frame mode outside the condensed water comb is discharged housing; The defective of said structure is when drip pipe or floss hole stop up because of foreign material etc., condensed water will be put aside in the condensed water collector groove, thereby purpose is collected in the discharging that can not reach condensed water, therefore will corrode water heater and environment, thereby water heater can't be worked, and cause potential safety hazard.
The utility model content
The utility model provides a kind of simple in structure in order to solve the prior art deficiency, ensures the safe and reliable condensed type combustion gas water heater anti-blocking safety control of condensed water.
The technical scheme that the utility model adopts in order to solve the problems of the technologies described above is as follows:
This condensed type combustion gas water heater is arranged on the condensate draining with the anti-blocking safety control of condensed water, it is characterized in that, is provided with the water level safety control in condensate draining, and this water level safety control is electrically connected with the condensing type water heater control device.
As further specifying of such scheme, described water level safety control is made of ball float in the condensate draining and the microswitch that is arranged on ball float top, and microswitch is electrically connected with the condensing type water heater control device.
Described water level safety control can also have other embodiment, and as being made of the water level sensor in the condensate draining, this inductor is electrically connected with the condensing type water heater control device.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: when discharging did not occur stopping up, the ball float height in the condensate draining did not reach the microswitch position, and condensed water flows out from floss hole; When drip pipe or floss hole stop up because of foreign material etc., condensed water will put aside in the condensed water collector groove, and ball float rises, and causes the microswitch interlock, and microswitch cuts off lights a fire, and can guarantee safe in utilization.
Description of drawings
Fig. 1 implements the status architecture schematic diagram for condensing type water heater of the present utility model is housed;
Fig. 2 is above-mentioned enforcement condensed water blocked state structural representation.
The specific embodiment
By Fig. 1, shown in Figure 2, this condensing type water heater is arranged on up and down between the first heat exchanger a and the second heat exchanger b with condensed water collecting device, water heater produces about 1500 ℃ high-temperature flue gas in burner part c burning back, behind the first heat exchanger a, absorb about 80% heat, flue gas drops to about 200 ℃, this cooling flue gas passes condensed water collecting device and enters the second heat exchanger part b, carry out secondary heat exchange, absorb about 15% heat, the flue-gas temperature of last discharge is reached below 80 ℃.Wherein in the second heat exchanger b, because being reduced in to produce after its surface condensation of cigarette institute temperature necessarily has corrosive condensed water, if condensed water flows on the first heat exchanger a and the burner c, will cause the corrosion of this part, water heater is damaged, can't operate as normal.
Condensed water collecting device is made of condensed water catch tray and condensate draining 3-1; The condensed water catch tray is fixed on the top of condensing type water heater outside framework, and it is provided with the stretching pyramidal structure of passage for the bottom low level, and condensate draining 3-1 is arranged on condensed water catch tray passage bottom, and condensate draining 3-1 area is greater than the passage area; Condensate draining 3-1 bottom is the height inclined-plane, also is connected with condensed water discharge outlet 3-2 on the condensate draining 3-1, and condensed water discharge outlet 3-2 is arranged on low level place, condensate draining 3-1 bottom.
As shown in Figure 1, condensed water of the present utility model is collected safety control and is made of ball float in the condensate draining 3-1 1 and the microswitch 2 that is arranged on ball float 1 top, and microswitch 2 is electrically connected with condensing type water heater control device 4.The convex shell fragment of one activity is set on the microswitch 2, and the shell fragment left side is positioned at directly over the control device 4, and shell fragment the right is positioned at directly over the ball float 1, and the centre is fixed by axle.
When discharging did not occur stopping up, as shown in Figure 1, the ball float 1 in the condensate draining did not reach microswitch 2 positions at control line place, and with the shell fragment interval, condensed water flows out from floss hole 3-2, the water heater operate as normal; When drip pipe or floss hole stop up because of foreign material etc., as shown in Figure 2, condensed water will be put aside in condensate draining 3-1, the water liquid level raises, ball float 1 also rises, and is connected with shell fragment to ball float 1, causes the interlock of microswitch 2, microswitch 2 cuts off igniting with condensing type water heater control device 4, can guarantee safe in utilization.
Described water level safety control can also have another kind of embodiment, promptly is made of the water level sensor in the condensate draining 3-1, and this inductor is electrically connected with the condensing type water heater control device.Its principle and microswitch are approximate, do not describe in detail at this.
